Impact of Menopause on Women Sexual Function Research Paper

Impact of Menopause on Women Sexual Function - Research Paper Example Thus, the menopause topic is timely because the impact the changes have on the life of the woman are challenging and thus worth addressing. In this regard, this paper will evaluate the impact of menopause on women sexual function. The evaluation will be achieved by reviewing five articles with studies conducted about the menopausal effects on sexuality. The review will involve comparing the approaches and methods the researchers use to arrive at their conclusions regarding the menopausal impacts. Key words: Menopause, women, Impact, function, and sex Impact of Menopause on Women Sexual function Different scholars have varying perspectives of approaching the topic on menopausal effects on women sexuality but the overall point that brings them together is that it results into sexuality dysfunction. Menopause changes the life of a woman through altering her biological social aspects (Mattar, Chong, Su, Agarwal, Wong, & Choolani, 2008). The authors continue to point out that it is a time when a woman begins to know the value and function of sexuality. This is because sexuality is important for her health as well as well-being. Menopause according to Mattar et al. (2008) interferes with hormones responsible for sexual response and thus become dysfunctional. The impact of the dysfunction is challenging, devastating, and can result into severe medical issues. In support of Mattar et al. (2008), leventhal (2000) reveals that menopause can reduce libido in women, orgasm as well as reducing coitus frequency. He continues to point out that these impacts result from physiological transformations because of menopause although Levenathal (2000) also adds that depression as well as marital discord could also cause the problems. The author claims that women undergoing menopausal changes experience difficulties in their sexuality, especially if they experience depression or discord. Thus the effects worsen because other hormones are affected and influence the negative effects o r rather ameliorate the transformations. To be more concise, Leventhal (2000) adds that the changes that occur are mediated by estrogen. Orgasm is the most affected sexuality in these women because they experience delays in secretions. This is in agreement with Matter et al. (2008) that inability to reach organism becomes a major challenge in menopausal women. On the impacts, Mattar et al. (2008) argue that the sexual dysfunction can lead to diminished sex drive, inability to arouse, orgasm issues, and pain when performing sex. The authors argue that the condition is complex and is hard to treat. Similarly, Dennerstein, Koochaki, Barton, and Graziottin (2006) survey reveals the challenging impact of menopause on the women’s sexual function. The authors reveal that menopausal women have challenging issues with their sexuality, especially reduced desire for sex. Additionally, the women have complications during sex such as inability for secretion thereby making orgasm a nightma re. According to Dennerstein et al. (2006), the menopausal women develop a Hypoactive sexual desire disorder (HSDD). The HSDD is common in almost all the menopausal women because the root cause is similar. The finding is similar to that of Mattar et al. (2008) and reveals that menopause impacts on women sexuality severely. The sexuality of older women is full of sexual challenges although some women have problems admitting it (Orner, 2005). The women experience some sexual urge although reduced in comparison to their youthful years but

Serum-hepatocyte Growth Factor (S-HGF) in Diagnosis of SPNs

Serum-hepatocyte Growth Factor (S-HGF) in Diagnosis of SPNs Value of hepatocyte growth factor in the differential diagnosis of solitary pulmonary nodules[F1] Haixin Yu, Yan Wang*, Wenduan Ma, Haixiang Yu, Shengtao Shang Abstract Purpose: To evaluate serum-hepatocyte growth factor (S-HGF) in the differentiation of solitary pulmonary nodules(SPNs)[F2].[F3] Methods: The study comprised 42 serum samples from SPN patients and 10 healthy samples as control. The HGF was measured by the commercially available immunoassay[F4].[F5] Serum levels of HGF of 42 patients with SPN was measured by ELISA kit, and compared with the control group of 10 normal subjects. The nodules were diagnosed by operation and pathology. Results: The median level of S-HGF was 180( range from 100 to 300) pg/ ml in the healthy control group, 165( range from 100 to 400) pg/ ml in benign SPNs group and while 395( range from 100 to 1550) pg/ ml in malignant SPNs group, The S-HGF mean level of malignant group was significantly higher than the with significant difference observed between the malignant group and control group(P. Moreover, the malignant group was also significantly higher than the , and between the malignant group and the benign group(Pwhile no significant difference between the benign , but not between the benign group and the control group(Pà ¯Ã‚ ¼Ã… ¾0.05). Furthermore, the S-HGF was also shown no statistically significant difference was observed(Pà ¯Ã‚ ¼Ã… ¾0.05) in different pathologic types of the limited number of lung cancer patients.In addition, when S-HGF in different pathologic types of the limited number of lung cancer patients were compared, no statistically significant difference was observed (Pà ¯Ã‚ ¼Ã… ¾0.05). Conclusion: S-HGF is valuable in the differential diagnosis of solitary pulmonary nodules. It was suggest that the patients with SPNs should consider an operation when the S-HGF level ≠¥250pg/ml, and malignant SPNs are highly suspected while S-HGF level ≠¥400pg/ml, surgical intervention should be taken immediately.S-HGF is valuable in the differential diagnosis of solitary pulmonary nodules. An elevated S-HGF level≠¥250pg/ml in patients with SPNs may strongly speak for malignant nodules and operation is suggested. If S-HGF level ≠¥400pg/ml, malignant SPNs are highly suspected, active surgical intervention should be taken. Key words: diagnosis, hepatocyte growth factor, solitary pulmonary nodule, NSCLClung cancer 1. Introduction The solitary pulmonary nodules (SPNs) is a single mass in the lung less than or equal to 3 cm in diameter, without concomitant pneumonia and atelectasis of involved lung segments and lobes [1]. In the general population, it’s reported that approximately 5% of SPN patients show lung cancer by radiology [2], which is considered one of the most common forms of cancer with a high death incidence ratio in the world [3]. Diagnoses of benign and malignant SPN has been concerned and become a challenge in these decades [4, 5]. Therefore, it is utmost important to improve the method in the characterization of SPNs[6].   With the development of modern medical science and technology, several detecting and monitoring method were used in screening the SPNs and lung cancer [2, 7, 8], Momen[9] et al. have compared three detection methods for identifying malignant SPNs for the sensitivity and specificity. The positron emission tomography (PET) imaging was consistently higher (80 to 100%) for its sensitivity, while was with lower specificity and larger variation (40 to 100%). Also, they found the similar results in dynamic CT with enhancement (sensitivity, 98 to 100%; specificity, 54 to 93%). In studies of CT-guided needle biopsy, sensitivity and specificity performed excellent, but nondiagnostic results were seen approximately 20%. Dalli[8] et al. also showed the similar result in 2013. While Carsten[10] et al. suggested that routine flexible bronchoscopy should be included in the pre-operative work-up of patients with SPNs in his study. Even so, it seems to find a better detection method of long cancer an d characterization of SPNs is still necessary. Serum-hepatocyte growth factor (S-HGF, Serum-HGF) is an important fibroblast-secreted protein that mediates development and progression of cancers[11]. Nagio et al. [12] gave the evidence that the S-HGF levels of patients with small cell lung cancer (SCLC) were significantly higher than those of patients with benign SPNs and healthy subjects. Ujiie et al[13] had proved that the levels of HGF in serum could be used as prognostic indicators of the patients with stage III non-small cell lung cancer (NSCLC) undergoing surgery and chemotherapy. Kasahara et al. [14] found that higher HGF levels were significantly associated with a shorter progression-free survival (PFS) and overall survival (OS) in patients with non-small cell lung adenocarcinoma. The expression level of S-HGF could be a sensitive indicator and an independent biomarker for evaluating the therapeutic effects and the prognosis in patients with lung cancer. Therefore, we give the hypothesis that S-HGF may be a potential targ et in diagnoses of benign and malignant SPNs associated with lung cancer. In our study, we used Enzyme linked immunospot assay (ELISA) method to detect the S-HGF levels between different serum samples from SPNs patients and healthy subjects. The solitary pulmonary nodule(SPN) is defined as a round opacity ≠¤3 cm in diameter surrounded by lung parenchyma[1].There should be no associated with hilar lymphadenopathy, atelectasis, pneumonia or chest wall pathologies. With more importance attached to physical examination and the development of medical imaging examination technology, the detection rate of SPN is on the increase. In the general population, approximately 5% of all SPNs shown by radiology are reported to be carcinomas[2]. In eight large trials of lung cancer screening, Momen et al[3] have compared the sensitivity and specificity in three detection methods for identifying malignant SPNs. The sensitivity of PET imaging was consistently high (80 to 100%), whereas specificity was lower and more variable (40 to 100%). They found similar results in dynamic CT with enhancement(sensitivity, 98 to 100%; specificity, 54 to 93%).In studies of CT-guided needle biopsy, sensitivity and specificity were excellent, but nondiagnostic results were seen approximately 20% of the time. Carsten et al[4], in a study of 225 patients with SPN of unknown origin, observed that the bronchoscopic biopsy results were positive in 84(46.5%) patients with lung cancer. The differential diagnosis between malignant and benign solitary pulmonary nodules (SPNs) is always a difficult point in clinical practice. In this study, we inv estigate the clinical significance of the serum level of hepatocyte growth factor(HGF) in patients with SPNs. 2. Methods 2.1.

(4)Chronic renal failure. (5)Arteriosclerosis. (6)Rheumatoid arthritis and osteoarthritis. (7)Diabetes mellitus. The case group included 42 patients with SPNs, mean age 60.7 years (range, 42 to 72). Besides, 10 healthy adult subjects were chosen as control. 2.2. Specimen collection The morning fasting venous blood of all subjects was collected in sterile polypropylene tubes, containing ethylenediamine tetraacetic acid (EDTA), and immediately centrifuged at 400rpm for 10min. Then, the plasma was stored at -70 °C until the assays were performed. 2.3. Assay for S-HGF We used Sandwich enzyme-linked immunosorbent assay(ELISA) to measure S-HGF. The HGF monoclonal antibody and standard substance for the assays were purchased from American RD systems. Goat-anti-human HGF polyclonal antibody as the primary antibody and donkey-anti-goat IgG polyclonal antibody labeled with horseradish peroxidase as the secondary antibody were both purchased from British biotech company Abcam. 2.4. Pathological diagnoses All the 42 patients with SPNs were pathological diagnosed postoperatively. 12 cases were benign nodules(4/12 were tuberculoma, 6/12 were inflammatory pseudotumor, 2/12 were hamartoma) and 30 cases were malignant nodules(17/30 were adenocarcinoma, 13/30 were squamous carcinoma). 2.5. Statistical methods All data were analyzed by SPSS 19.0. Because the measured data manifested as skewed distribution, geometrical mean Gà ¯Ã‚ ¼Ã‹â€ logG ±sà ¯Ã‚ ¼Ã¢â‚¬ °was calculated in each group after logarithmic transformation had been carried out on each datum.

Discussion Hepatocyte growth factor/scatter factor (HGF/SF) from the serum of hepatectomized rats was first partially purified and described by Nakamura in 1984[15]. HGF receptor encoded by the c-met proto-oncogene is a member of the tyrosine kinase class of cell surface receptors. As a kind of cytokine, the hepatocyte growth factor(HGF) has widely biological activities, including regeneration, antifibrosis, cytoprotection, and differentiation[16]. Moreover, HGF is a predominant fibroblast-derived factor that stimulates mitogenesis, motogenesis, and the invasion and metastasis of human carcinoma cells [17]. The growth and metastasis of tumors depend on angiogenesis which is the result of the imbalance of promoters and inhibitors. The S-HGF levels in patients with acute hepatitis, chronic hepatitis and cirrhosis were found to be slightly higher than those in normal subjects[18]. So the patients with various liver and gall diseases were first excluded. So far, some studies showed the S-HGF levels were significantly increased in patients with Inflammation, infection, underwent surgery or trauma. Therefore, the patients with inflammation or infection within a month and the patients underwent surgery or trauma within 6 months were both excluded. Johanna et al. [19] had concluded that patients with chronic renal failure (CRF) have a systemic HGF profile reflecting a chronic inflammatory condition with high concentration, but low biological activity, of HGF. Therefore, the patient samples with CRF were also excluded. The S-HGF levels in patients with arteriosclerosis, rheumatoid arthritis, osteoarthritis, and diabetes mellitus were reported to be significantly higher than that in healthy population. So, the patients with these diseases were excluded as well. Tsao et al.[20] showed the HGF messenger RNA(mRNA) and protein were predominantly expressed by the tumor cells in a high percentage of primary NSCLC. Our study showed serum of the healthy control group contained trace amounts of S-HGF, the S-HGF levels of the patients with benign SPNs were nearly close to the healthy control group(PHGF levels of the patients with malignant SPNs were significantly higher than the healthy control group(Pà ¯Ã‚ ¼Ã… ¾0.05) and the benign SPNs group(Pà ¯Ã‚ ¼Ã… ¾0.05). It illustrated that the high level of S-HGF was associated with lung cancer. And it was further confirmed that S-HGF could be expressed by the carcinoma cells in NSCLC. The S-HGF levels of part of patients with squamous carcinoma in the malignant SPNs group were observed to be higher(à ¯Ã‚ ¼Ã… ¾700pg/ml) and the S-HGF statistical analysis by the statistical difference between the squamous carcinoma group and adenocarcinoma group, for the S-HGF, the median level of the squamous carcinoma group was 370(100-1500)pg/ml while the adenocarcinoma group was 420(100-1550)pg/ml, no statistically significant difference between the two groups(P>0.05). No further conclusions could be made, in case of the number limitation of the samples. The result confirmation should be amortized awaits further research. Further analysis of the 20 patients with high levels of S-HGF(≠¥250pg/ml), there are 3 patients(15%) with benign SPNs and 17 patients(85%) with malignant SPNs. Furthermore, for the 20 patients, the result shows that 1 patients (6.25%) with benign SPNs and 15 patients (93.75%) with malignant SPNs in the 16 patients with high levels of S-HGF(≠¥400pg/ml), It reveals that an elevated S-HGF level ≠¥250pg/ml in patients with SPNs are more likely to be malignant and when the S-HGF level ≠¥400pg/ml, malignant SPNs are highly suspected. Conclusion In conclusion, our study shows significant in the differential diagnosis between malignant and benign solitary pulmonary nodules (SPNs) for the S-FGF assay. The S-HGF levels of malignant SPNs group are significantly higher than the healthy control group(P SPNs group(Pà ¯Ã‚ ¼Ã…“0.05). The differences between benign SPNs group and healthy control group have no statistically significant(Pà ¯Ã‚ ¼Ã… ¾0.05). An elevated S-HGF level ≠¥250pg/ml in patients with SPNs are more likely to be malignant, surgical therapy should be considered. If S-HGF level ≠¥400pg/ml, malignant SPNs are highly suspected, surgical intervention is recommended without delay. Hepatocyte growth factor/scatter factor (HGF/SF) from the serum of hepatectomized rats was partially purified and described by Nakamura for the first time in 1984. HGF receptor encoded by the c-met proto-oncogene is a member of the tyrosine kinase class of cell surface receptors.

Moreover, HGF is a predominant fibroblast-derived factor that stimulates mitogenesis, motogenesis, and the invasion and metastasis of human carcinoma cells[6]. The growth and metastasis of tumors depend on angiogenesis which is the result of the imbalance of promoters and inhibitors. Sengupta et al[7] had demonstrated that HGF/SF could induce angiogenesis independently of VEGF, possibly through the direct activation of the Akt and ERKs. The S-HGF levels in patients with acute hepatitis, chronic hepatitis and cirrhosis were found to be slightly higher than those in normal subjects[8]. So the patients with various liver and gall diseases were first excluded. So far, some studies have found the S-HGF levels were significantly increased in patients with Inflammation or infection, or underwent surgery or trauma. Therefore, the patients with inflammation or infection within a month and the patients underwent surgery or trauma within 6 months were both excluded.

The S-HGF levels in patients with arteriosclerosis, rheumatoid arthritis, osteoarthritis, and diabetes mellitus were reported to be significantly higher than that in healthy population. So, the patients with these diseases were all excluded. Tsao et al[10] had showed that HGF messenger RNA(mRNA) and protein were predominantly expressed by the tumor cells in a high percentage of primary NSCLC. It indicated in our research that the serum of the healthy control group only contained trace amounts of S-HGF, the levels of S-HGF of the patients with benign SPNs were close to those of the healthy control group(Pà ¯Ã‚ ¼Ã… ¾0.05) and the benign SPNs group(Pà ¯Ã‚ ¼Ã… ¾0.05). It illustrated the fact that high level of S-HGF was associated with lung cancer. And, it was further confirmed that S-HGF could be expressed by the carcinoma cells in NSCLC. In addition, Nagio et al[11] had proved that the levels of S-HGF of patients with SCLC were significantly higher than those of patients with benign SPNs and healthy subjects. The levels of S-HGF of a portion of patients with squamous carcinoma in the malignant SPNs group were observed to be higher(à ¯Ã‚ ¼Ã… ¾700pg/ml) and statistical analysis was conducted to fond the statistical difference of S-HGF between the squamous carcinoma group and the adenocarcinoma group. The S-HGF median of the squamous carcinoma group was 370(100-1500)pg/ml and the adenocarcinoma group was 420(100-1550)pg/ml, no statistically significant difference was found between the two groups(P>0.05). No firm conclusions could be made, possibly due to the limited number of cases. It is of concern and remains to be further studied. Further analysis was taken in 20 patients with high levels of S-HGF(≠¥250pg/ml), 3 patients(15%) had benign SPNs and 17 patients(85%) had malignant SPNs. Further observation was made, among the 20 patients, there were 16 patients with high levels of S-HGF(≠¥400pg/ml), 1 patients(6.25%) had benign SPNs and 15 patients(93.75%) had malignant SPNs. It reveals that an elevated S-HGF level ≠¥250pg/ml in patients with SPNs are more likely to be malignant and if S-HGF level ≠¥400pg/ml, malignant SPNs are highly suspected. Ujiie et al[11] had proved that the levels of HGF in serum could be useful prognostic indicators of the survival of patients with stage III NSCLC undergoing surgery and chemotherapy. Kasahara et al[12] had shown that higher HGF levels were significantly associated with a shorter progression-free survival (PFS) and overall survival (OS) in patients with non-small cell lung adenocarcinoma. The expression level of S-HGF could be a sensitive indicator and an independent judgement standard for evaluating the therapeutic effects and the prognosis in patients with lung cancer. Furthermore, understanding the role of HGF in the tumor progression may help in designing new therapeutic strategies for lung cancer. In conclusion, the assay for S-HGF may be of some significance in the differential diagnosis between malignant and benign solitary pulmonary nodules(SPNs). The S-HGF levels of malignant SPNs group were significantly higher than those of healthy control group(Pà ¯Ã‚ ¼Ã…“0.05). The differences between benign SPNs group and healthy control group had no statistically significant(Pà ¯Ã‚ ¼Ã… ¾0.05). An elevated S-HGF level ≠¥250pg/ml in patients with SPNs are more likely to be malignant, surgical therapy should be suggested. If S-HGF level ≠¥400pg/ml, malignant SPNs are highly suspected, active surgical intervention should be taken.

The Feminine Religious Experience in Victorian Times Essay -- Victoria

The Feminine Religious Experience: Beyond the â€Å"Angel in the House† The conception of the Victorian woman as the pious repository for her family's stockpile of religiosity consistently permeates contemporary notions of the gender roles of the era. However, the idealized role of the â€Å"angel in the house† was often simply that - an ideal rather than a reality. Women's involvement in religion and spirituality varied widely based on class and level of devotion. Though the majority of women's religious duty consisted of assisting charitable works sponsored by parishes (Heeney 330), women were also employed as local missionaries. The era also witnessed the revival of the convent as an alternative avenue for women of all classes. For the Victorian-era upper middle class family of the Pagets of London, the women received a Christian education in terms of learning the Bible and reciting psalms. In adulthood they fulfilled their Christian duty by volunteering for and donating to various charities for the poor and/or feeble-minded (Peterson 692) However, the private letters of the Paget women often indicate that their helping the poor was not inspired by an altruistic love of all God's creatures, as the â€Å"angel the house† myth would lead one to believe. Instead these were societal obligations, on par with social calls to friends: Catherine Paget wrote â€Å"I spent the morning seeing poor people, the afternoon calling on rich ones.† (Peterson 706) Lydia Paget also wrote, â€Å"†¦I always go with such reluctance to visit the poor people under our care; when I once get amongst them I quite enjoy myself, but on setting out I feel inclined to bend my steps in any other direction rather than th e right.† (Peterson 706) Beyond charity work, women also... ...t beyond embodying the moral and spiritual core of the family.

Causation of Crime Essay

The two theories I chose to compare and contrast are the Trait and Choice theories. These two theories explain why people commit crimes but differ in reasoning. I found that the main difference in between the two is that the choice theory states that if people want to commit a crime they will if the benefits outweighs the punishment. The trait theory differs because it deals with testosterone and whether or not people with lower IQ’s are more liable to commit crimes. When looking at the two theories you will see that the first theory is more straightforward and the second one leans more towards taking the blame away from the individual and placing it their traits. I like the fact that the choice theory states that if a person is going to commit a crime they are going to do it. Not only does this theory cover the fact that the person committing the crime weighs his or her options but might also do it out of enjoyment of act. The trait theory takes the responsibility away from the individual and places it on traits such as testosterone. I feel that this theory allows people to commit crimes and later on say that it was due to producing too much testosterone or use their IQ as an excuse to escape the fact that they committed a crime. Making the person accept responsibility for their actions it what should happen and the choice theory seems to lean more towards that as opposed to the trait theory. I would associate the guns and crime trend to the choice theory. The reason for this is because most people who commit crimes with guns already have the intention to use it. This means that they already made up their minds and have chosen to commit the crime. For instance gang crimes that involve guns, these individuals use guns, in their minds, to gain territory or even for retaliation. In a ten year span that covers 1997 -2007 there were 650 homicides (Krueger, 2007), this means that 650 times the people have made the conscious choice to kill someone. Out of those numbers, 290 of them have been by shootings (Krueger, 2007). That is some real food for thought when you add the choice theory into the equation. Gutierrez, K. (2007). Albuquerque metro area saw 54 homicides in 2007. Scripps Newspaper Group. Retrieved from: http://www.abqtrib.com

Animal Nutrition: Distinguish Macronutrients and Micronutrients Essay

There are seven major classes of nutrients: carbohydrates, fats, fiber, minerals, protein, vitamin, and water. These nutrient classes can be categorized as either macronutrients (needed in relatively large amounts) or micronutrients (needed in smaller quantities). The macronutrients are carbohydrates, fats, fiber, proteins, and water. The micronutrients are minerals and vitamins. The macronutrients (excluding fiber and water) provide structural material (amino acids from which proteins are built, and lipids from which cell membranes and some signaling molecules are built) and energy. Some of the structural material can be used to generate energy internally, and in either case it is measured in joules or calories (sometimes called â€Å"kilocalories† and on other rare occasions written with a capital C to distinguish them from little ‘c’ calories). Carbohydrates and proteins provide 17 kJ approximately (4 kcal) of energy per gram, while fats provide 37 kJ (9 kcal) per gram.,[1] though the net energy from either depends on such factors as absorption and digestive effort, which vary substantially from instance to instance. Vitamins, minerals, fiber, and water do not provide energy, but are required for other reasons. A third class dietary material, fiber (i.e., non-digestible material such as cellulose), seems also to be required, for both mechanical and biochemical reasons, though the exact reasons remain unclear. Molecules of carbohydrates and fats consist of carbon, hydrogen, and oxygen atoms. Carbohydrates range from simple monosaccharides (glucose, fructose, galactose) to complex polysaccharides (starch). Fats are triglycerides, made of assorted fatty acid monomers bound to glycerolbackbone. Some fatty acids, but not all, are essential in the diet: they cannot be synthesized in the body. Protein molecules contain nitrogen atoms in addition to carbon, oxygen, and hydrogen. The fundamental components of protein are nitrogen-containing amino acids, some of which areessential in the sense that humans cannot make them internally. Some of the amino acids are convertible (with the expenditure of energy) to glucose and can be used for energy production just as ordinary glucose. By breaking down existing protein, some glucose can be produced internally; the remaining amino acids are discarded, primarily as urea in urine. This occurs normally only during prolonged starvation.

They constitute a large part of foods such as rice, noodles, bread, and other grain-based products. Monosaccharides contain one sugar unit, disaccharides two, and polysaccharides three or more. Polysaccharides are often referred to as complex carbohydrates because they are typically long multiple branched chains of sugar units. The difference is that complex carbohydrates take longer to digest and absorb since their sugar units must be separated from the chain before absorption. The spike in blood glucose levels after ingestion of simple sugars is thought to be related to some of the heart and vascular diseases which have become more frequent in recent times. Simple sugars form a greater part of modern diets than formerly, perhaps leading to more cardiovascular disease. The degree of causation is still not clear, however. Fat A molecule of dietary fat typically consists of several fatty acids (containing long chains of carbon and hydrogen atoms), bonded to a glycerol. They are typically found as triglycerides (three fatty acids attached to one glycerol backbone). Fats may be classified as saturated or unsaturateddepending on the detailed structure of the fatty acids involved. Saturated fats have all of the carbon atoms in their fatty acid chains bonded to hydrogen atoms, whereas unsaturated fats have some of these carbon atoms double-bonded, so their molecules have relatively fewer hydrogen atoms than a saturated fatty acid of the same length. Unsaturated fats may be further classified as monounsaturated (one double-bond) or polyunsaturated (many double-bonds). Furthermore, depending on the location of the double-bond in the fatty acid chain, unsaturated fatty acids are classified as omega-3 or omega-6 fatty acids. Trans fats are a type of unsaturated fat with trans-isomer bonds; these are rare in nature and in foods from natural sources; they are typically created in an industrial process called (partial) hydrogenation. Many studies have shown that unsaturated fats, particularly monounsaturated fats, are best in the human diet. Saturated fats, typically from animal sources, are next, while trans fats are to be avoided. Saturated and some trans fats are typically solid at room temperature (such as butter orlard), while unsaturated fats are typically liquids (such as olive oil or flaxseed oil). Trans fats are very rare in nature, but have properties useful in the food processing industry, such as rancid resistance.[citation needed] Essential fatty acids Most fatty acids are non-essential, meaning the body can produce them as needed, generally from other fatty acids and always by expending energy to do so. However, in humans at least two fatty acids are essential and must be included in the diet. An appropriate balance of essential fatty acids -— omega-3 and omega-6 fatty acids -— seems also important for health, though definitive experimental demonstration has been elusive. Both of these â€Å"omega† long-chain polyunsaturated fatty acids are substrates for a class of eicosanoids known as prostaglandins, which have roles throughout the human body. They are hormones, in some respects. The omega-3 eicosapentaenoic acid (EPA), which can be made in the human body from the omega-3 essential fatty acid alpha-linolenic acid (LNA), or taken in through marine food sources, serves as a building block for series 3 prostaglandins (e.g. weakly inflammatory PGE3). The omega-6 dihomo-gamma-linolenic acid (DGLA) serves as a building block for series 1 prostaglandins (e.g. anti-inflammatory PGE1), whereas arachidonic acid (AA) serves as a building block for series 2 prostaglandins (e.g. pro-inflammatory PGE 2). Both DGLA and AA can be made from the omega-6 linoleic acid (LA) in the human body, or can be taken in directly through food. An appropriately balanced intake of omega-3 and omega-6 partly determines the relative production of different prostaglandins: one reason a balance between omega-3 and omega-6 is believed important for cardiovascular health. In industrialized societies, people typically consume large amounts of processed vegetable oils, which have reduced amounts of the essential fatty acids along with too much of omega-6 fatty acids relative to omega-3 fatty acids. The conversion rate of omega-6 DGLA to AA largely determines the production of the prostaglandins PGE1 and PGE2. Omega-3 EPA prevents AA from being released from membran es, thereby skewing prostaglandin balance away from pro-inflammatory PGE2 (made from AA) toward anti-inflammatory PGE1 (made from DGLA). Moreover, the conversion (desaturation) of DGLA to AA is controlled by the enzyme delta-5-desaturase, which in turn is controlled by hormones such as insulin (up-regulation) and glucagon (down-regulation). The amount and type of carbohydrates consumed, along with some types of amino acid, can influence processes involving insulin, glucagon, and other hormones; therefore the ratio of omega-3 versus omega-6 has wide effects on general health, and specific effects on immune function and inflammation, and mitosis (i.e. cell division). Good sources of essential fatty acids include most vegetables, nuts, seeds, and marine oils,[2] Some of the best sources are fish, flax seed oils, soy beans, pumpkin seeds, sunflower seeds, and walnuts. Fiber Dietary fiber is a carbohydrate (or a polysaccharide) that is incompletely absorbed in humans and in some animals. Like all carbohydrates, when it is metabolized it can produce four calories (kilocalories) of energy per gram. But in most circumstances it accounts for less than that because of its limited absorption and digestibility. Dietary fiber consists mainly of cellulose, a large carbohydrate polymer that is indigestible because humans do not have the required enzymes to disassemble it. There are two subcategories: soluble and insoluble fiber. Whole grains, fruits (especiallyplums, prunes, and figs), and vegetables are good sources of dietary fiber. Fiber is important to digestive health and is thought to reduce the risk of colon cancer.[citation needed] For mechanical reasons it can help in alleviating both constipation and diarrhea. Fiber provides bulk to the intestinal contents, and insoluble fiber especially stimulates peristalsis — the rhythmic muscular contractions of the intestines which move digesta along the digestive tract. Some soluble fibers produce a solution of high viscosity; this is essentially a gel, which slows the movement of food through the intestines. Additionally, fiber, perhaps especially that from whole grains, may help lessen insulin spikes and reduce the risk of type 2 diabetes. Protein Proteins are the basis of many animal body structures (e.g. muscles, skin, and hair). They also form the enyzmes which control chemical reactions throughout the body. Each molecule is composed of amino acids which are characterized by inclusion of nitrogen and sometimes sulphur (these components are responsible for the distinctive smell of burning protein, such as the keratin in hair). The body requires amino acids to produce new proteins (protein retention) and to replace damaged proteins (maintenance). As there is no protein or amino acid storage provision, amino acids must be present in the diet. Excess amino acids are discarded, typically in the urine. For all animals, some amino acids are essential (an animal cannot produce them internally) and some are non-essential (the animal can produce them from other nitrogen-containing compounds). About twenty amino acids are found in the human body, and about ten of these are essential, and therefore must be included in the diet. A diet that contains adequate amounts of amino acids (especially those that are essential) is particularly important in some situations: during early development and maturation, pregnancy, lactation, or injury (a burn, for instance). A complete protein source contains all the essential amino acids; an incomplete protein source lacks one or more of the essential amino acids. It is possible to combine two incomplete protein sources (e.g. rice and beans) to make a complete protein source, and characteristic combinations are the basis of distinct cultural cooking traditions. Sources of dietary protein include meats, tofu and other soy-products, eggs, grains, legumes, and dairy products such as milk and cheese. A few amino acids from protein can be converted into glucose and used for fuel through a process called gluconeogenesis; this is done in quantity only during starvation. The amino acids remaining after such conversion are discarded. Vitamins As with the minerals discussed above, some vitamins are recognized as essential nutrients, necessary in the diet for good health. (Vitamin D is the exception: it can alternatively be synthesized in the skin, in the presence of UVB radiation.) Certain vitamin-like compounds that are recommended in the diet, such as carnitine, are thought useful for survival and health, but these are not â€Å"essential† dietary nutrients because the human body has some capacity to produce them from other compounds. Moreover, thousands of different phytochemicals have recently been discovered in food (particularly in fresh vegetables), which may have desirable properties including antioxidant activity (see below); experimental demonstration has been suggestive but inconclusive. Other essential nutrients not classed as vitamins include essential amino acids (see above),choline, essential fatty acids (see above), and the minerals discussed in the preceding section. Vitamin deficiencies may result in disease conditions: goitre, scurvy, osteoporosis, impaired immune system, disorders of cell metabolism, certain forms of cancer, symptoms of premature aging, and poor psychological health (including eating disorders), among many others.[6] Excess of some vitamins is also dangerous to health (notably vitamin A), and for at least one vitamin, B6, toxicity begins at levels not far above the required amount. Deficiency or excess of minerals can also have serious health consequences. Water About 70% of the non-fat mass of the human body is made of water[7] . Analysis of Adipose Tissue in Relation to Body Weight Loss in Man. Retrieved from Journal of Applied To function properly, the body requires between one and seven liters of water per day to avoid dehydration; the precise amount depends on the level of activity, temperature, humidity, and other factors.[citation needed] With physical exertion and heat exposure, water loss increases and daily fluid needs will eventually increase as well. It is not fully clear how much water intake is needed by healthy people, although some experts assert that 8–10 glasses of water (approximately 2 liters) daily is the minimum to maintain proper hydration.[8] The notion that a person should consume eight glasses of water per day cannot be traced to a credible scientific source.[9] The effect of, greater or lesser, water intake on weight loss and on constipation is also still unclear.[10] The original water intake recommendation in 1945 by the Food and Nutrition Board of the National Research Council read: â€Å"An ordinary standard for diverse persons is 1 milliliter for each calorie of food. Most of this quantity is contained in prepared foods.†[11] The latest dietary reference intake report by theUnited States National Research Council recommended, generally, (including food sources): 2.7 liters of water total for women and 3.7 liters for men.[12] Specifically, pregnant and breastfeeding women need additional fluids to stay hydrated. According to the Institute of Medicine—who recommend that, on average, women consume 2.2 litres and men 3.0 litres—this is recommended to be 2.4 litres (approx. 9 cups) for pregnant women and 3 litres (approx. 12.5 cups) for breastfeeding women since an especially large amount of fluid is lost during nursing.[13] For those who have healthy kidneys, it is somewhat difficult to drink too much water,[citation needed] but (especially in warm humid weather and while exercising) it is dangerous to drink too little. People can drink far more water than necessary while exercising, however, putting them at risk of water intoxication, which can be fatal. In particular large amounts of de-ionized water are dangerous. Normally, about 20 percent of water intake comes in food, while the rest comes from drinking water and assorted beverages (caffeinated included). Water is excreted from the body in multiple forms; including urine and feces, sweating, and by water vapor in the exhaled breath.
