To infect its host, the respiratory pathogen. Pseudomonas aeruginosa takes an ordinary protein usually involved in protein synthesis and adds three small molecules to turn it into a key virulence factor according to a study in mbio this week, economically employing one protein in two different ways. Scientists at Emory University School of Medicine, the University of Virginia, and Universidad de las Islas Baleares in Mallorca, spain, uncover this previously unknown virulence factor. Aeruginosa, one of the most common causes of hospital-acquired pneumonia.

Through a series of biochemical tests, the three discovered that the patient had a cerebrospinal fluid deficiency in biopterin, a protein involved in the synthesis of several neurotransmitters. After receiving an analogue of biopterin to correct the deficiency, the patients depression symptoms largely disappeared; today he is a thriving college student. The success prompted the researchers to examine other young adults with depression who were not responding to treatment, explained Pan. In the published trial, the researchers looked for metabolic abnormalities in 33 adolescents and young adults with treatment-resistant depression and 16 healthy people. Although the specific metabolites affected differed among patients, the researchers found that 64 percent of the patients had a deficiency in neurotransmitter metabolism, compared with none of the control group. In almost all of these patients, treating the underlying deficiency improved their depression symptoms, and some patients even experienced complete remission. In addition, the further along the patients progress in the treatment, the better they are getting, pan reported. Its really exciting that we now have another avenue to pursue for patients for whom our currently getting available treatments have failed, she said. This is a potentially transformative finding for certain groups of people with depression. The study was published in the.

Moderate amount of whey proteins actually do not show any adverse effects on us but side effects occur when whey protein is consumed in substantial amounts. If you are allergic to cow milk, you most probably will also be allergic to whey protein. The allergy is most often caused by beta-lactoglobulin. Very high doses of whey protein can also cause stomach pains and cramps, reduced appetite, tiredness, headache, and nausea. Identifying and treating metabolic deficiencies in patients with treatment-resistant depression can improve symptoms and in some cases even lead to remission, according to new research. Whats really promising about these new findings is that they indicate that there may be physiological mechanisms underlying depression that we can use to improve the quality of life in patients with this disabling illness, said david Lewis,. D., a professor and chair of the University of Pittsburgh School of Medicines Department of Psychiatry (upmc). Major depressive disorder, usually referred to simply as depression, affects nearly 15 million American adults and is one of the most common mental disorders. Unfortunately, at least 15 percent of patients dont find relief from conventional treatments, such as antidepressant medications and psychotherapy, said lead study investigator Lisa pan,.

A study published in the journal of dairy Sciences indicated that consuming fermented milk with whey protein concentrate can significantly increase hdl cholesterol, lower triglycerides, and lower systolic blood pressure. Prevents or Lowers Risk of Diseases / Disorders Whey proteins contain number writing of bioactive components that help prevent or lower risk of certain diseases. For example, whey protein stimulates immunity and detoxifies potential carcinogens, thus preventing cancers. Similarly, research has shown that whey protein supplementation for 8 weeks had variable effects of hepatitis virus infection. Glutathione deficiency is one of the problems associated with hiv infection. Research has shown that 2-week oral supplementation of 45g of whey protein daily significantly increased glutathione levels in hiv infected people.

Whey protein increases bone mineral density and thus prevents osteoporosis. Studies handwriting have also shown that whey protein improves cognitive function and coping ability in highly stressed individuals. Last but not the least, whey protein has a protective effect on stomach lining. Studies have shown that alpha-lactalbumin in whey protein significantly reduces ulcerative lesions. Side effects of Whey protein Whey protein maybe a super food with numerous health benefits but it certainly does have its share of side effects.

Builds Muscle mass Body builders and athletes are known to take whey protein shakes or supplements as part of their customized diet. This is because the branched-chain amino acid leucine (as already mentioned earlier) acts as a signaling molecule to initiate protein synthesis and improve bmi in those who exercise. Although studies on effect of whey proteins on muscle size and strength are limited, studies show that men engaged in resistance training improved their strength when they were given whey protein supplementation. For example, a study showed that muscular performance in men improved significantly when they were given 10g of whey protein supplements twice daily for 3 months. Prevents Obesity Whey protein isolates are very high in proteins (approximately 95 percent) and contain almost no fat and sugars or lactose. This makes it an ideal food if you want to avoid putting on weight.

Further, scientists believe that whey contains calcium which along with other bioactive components in whey increase breakdown of fat cells and reduce formation of fat cells. Unfortunately, whey proteins with or without calcium can only prevent obesity but do not really have any impact on those who are already obese or overweight. Prevents Colds Interestingly, new studies on whey protein show that inclusion of whey protein in the diet significantly decreases the incidence of colds and cold-related symptoms. Researchers from University of queensland, australia, suggested a combination of lactoferrin and whey protein Ig fraction (LF /IgF) to be used as preventive supplement for colds. Reduces Risk of Cardiovascular Disease high fat diet and the preference for processed foods makes us prone to cardiovascular disease. We also know that milk must always be a part of a healthy diet.

Improves Gastrointestinal Immunity evernote in Infants Whey protein infant formula is a good option for babies that cannot be breastfed for some reason. Studies have indicated that whey fed infants (less than 2 weeks old) had richer beneficial gut microbes as compared to those on cow-milk formula. These microbes could possibly provide two important benefits: They improved gastrointestinal immunity by reducing colonization homework of harmful bacteria in the stomach and gut. They also decreased the risk of developing atopic disease. Another study published in the journal Pediatrics indicated that whey formula could reduce infantile colic. Infantile colic is described when an infant cries for 3 hours at least 3 times a week for at least 3 weeks. The study showed that babies given whey formula cried at least one hour less per day as compared with babies given cows milk.

This nursery rhyme indicates that over the centuries people have known and accepted the importance of milk components - casein and whey, as part of the healthy diet. The health benefits of whey protein range from muscle building to reducing obesity to preventing many chronic diseases and disorders. Increases Life Span, reduced appetite and impaired nutrient absorption leads to inadequate nourishment in the elderly, which means they dont get sufficient quality protein. And this is the reason why their muscle mass and bone mass decreases. They have low immunity and their cognitive ability declines. This called frailty syndrome. Given the fact that intake of insufficient protein increases the risk of mortality in the aged, whey protein could be a possible solution to preventing frailty. Whey protein contains leucine, isoleucine the and valine that help prevent protein breakdown and stimulate protein synthesis.

form of whey protein contains almost no fat and lactose, and their protein content ranges from 90 to 95 percent. It is a rapidly digestible form of whey protein. hydrolysate - this is the most digestible form of whey protein because hydrolysates are formed by breaking down the amino acids further into peptides. This is the fastest way we can provide our muscles with amino acids. Whey protein Benefits, little miss Muffet, sat on a tuffet. Eating her curds (casein) and whey.

Alpha-lactalbumin - this protein paper is essential for milk synthesis. Other whey proteins include : Immunoglobulins - these are antibodies especially high in colostrum, serum proteins, whey is a rich source of amino acids leucine, isoleucine and valine. These amino acids help in the process of protein synthesis; consequently, they help in repair and growth of muscle tissue. Thats why whey protein is so popular with bodybuilders and athletes. Another important amino acid in whey is cysteine. This amino acid helps boost the immune system. Apart from the above mentioned, whey proteins also have many enzymes, hormones, growth factors, disease resistance factors, and other important components. Another plus point for whey protein is that our body absorbs more whey protein than most other forms of protein, that is, they have high bioavailability. This is the reason infants and seniors alike can digest this protein easily.

What food is popular with those who want to add muscle mass as well with those who want to lose weight? Which type of protein is equally important for infants as also for older adults? You guessed it right, it is whey protein. Milk contains a number of specific proteins, primary protein being the casein. Basically, when casein is removed from milk, the protein left in the milk is whey protein. Whey is the watery portion of milk that separates from the curds when making cheese or when making paneer. Whey protein contains all nine essential amino acids and it is also low in lactose content. So it is the ideal source of protein for the young and old, the thin and the fat, as well as for those who are healthy or those who are recuperating from a disease. Whey proteins in Milk, major whey proteins in milk are: beta-lactoglobulin - although no definitive function is attributed to this protein, scientists believe it functions primarily for binding fatty acids and retinol.
