Leucine protein synthesis accelerator
Sunday, April 27, 2014
Muscle tension , amino acid levels in the blood, particularly leucine, as well as insulin , are key factors in the development of muscle tissue and metabolic pathways that activate signals inside of cells that promote protein synthesis in muscle and slow degradation , accelerating the remodeling and repair.
Some biochemical substances called ribosomal protein S6 kinase and objetibo rapamycin (mTOR ) are important communicating molecules that are sensitive to changes in energy status and determinants in protein synthesis . Function as biological programs to align the amino acids needed to produce new muscle tissue.
Researchers at the Medical Division of the University of Texas, USA , have concluded that weight training after administration of a high leucine supplement communicating activated protein molecules that promote protein synthesis and muscle growth .
Leucine is an essential branched principal called , BCAA amino acid and theore the use of these is very positive for bodybuilders.
I hope you find it helpful, comment and suggest . And do not forget to share !
Chronic Stress Promotes Protein Brain Tangles and Risk of Alzheimer’s Disease
Wednesday, April 9, 2014
Alzheimer’s disease is characterized by an initial loss of short term memory and the ability to form rational and permanent thoughts. Protein tangles known as tau aggregates strangle neural synapses, blocking the vital flow of neurotransmitter and electrical signals necessary to form memories and personality. Once considered a disease of the aging, this form of dementia is increasing at a startling rate in younger individuals, largely due to a processed and ined food diet, environmental factors and long-term chronic stress.
Researchers from the University of California, San Diego School of Medicine have published the result of a study in the Proceedings of the National Academy of Sciences, explaining the mechanism behind continual exposure to stressors so common in our rapid-paced lifestyle, and the unnatural accumulation of insoluble tau protein aggregates in brain tissue. They explain that neurofibrillary tangles are one of the physical hallmark signs of Alzheimer’s disease, and have been shown to contribute to disease progression in people under chronic stress conditions during the course of past studies.
Chronic Stress is Positively Linked to Physical Brain Changes Leading to Alzheimer’s Dementia
The study team, using a mouse-based model, noted “we found that repeated episodes of emotional stress, which has been demonstrated to be comparable to what humans might experience in ordinary life, resulted in the phosphorylation and altered solubility of tau proteins in neurons… these events are critical in the development of NFT pathology in Alzheimers disease.” Researchers determined that the effect was most pronounced in the hippocampus of the brain, an area linked to the formation, organization and storage of memories.

The scientists are quick to note that the type of stress that is associated with the development of tangles in the brain is not acute stress, defined as a single, passing episode. They determined that chronic, long term stress that never ceases is far more threatening to the brain and promotes tau protein aggregates to accumulate. Acute stress is actually considered useful for brain plasticity and helps to facilitate learning.
Engage in Stress Reduction Techniques to Reduce Stress and Disease Risk
Chronic stress continually stimulates and activates stress pathways in the brain that lead to pathological alteration of stress circuitry in the brain. The researchers describe chronic stress as too much of a good thing gone bad. Lead study author, Dr. Robert Rissman commented on their findings “As people age, perhaps their neuronal circuits do too, becoming less robust and perhaps less capable of completely rebounding from the effects of stress.”

Certainly we cannot entirely eliminate stress from our daily lives, and the results of this study conclude that small amounts of acute stress are important to maintain brain plasticity and for the formation of new memories. The problem arises when the level of stress never abates, and our brain is unable to recover from the massive amount of new stimuli we experience from chronic stress. Reduce your stress level to a minimum, as this will provide yet another crucial lifestyle modification that can help prevent chronic illness and ward off Alzheimer’s disease.
Protein Intake The key for long term weight loss
Tuesday, April 1, 2014
Well, that weight lifter guzzling down a protein shake at your local fitness centre is onto something -- the latest cutting edge analysis reveals that doubling your personal protein consumption, coupled with working out, could be the key to losing fat pounds without losing lean muscle.
We all know a sufficient amount of protein (especially after a workout) is key to building and repairing muscular tissues, yet a recent analysis, circulated in the September issue of The FASEB Journal, suggests that we might not be having enough. The studys investigators placed 39 subjects on a weight-loss routine over 31 calendar days; to begin with, all of the participants were on the same exact diet plan to maintain their current body mass. After ten days, they were separated into 3 groups following calorie-restricted weight loss plans: those people that consumed the US-recommended daily allowance (RDA) of protein, individuals that ingested twice the RDA of required protein, and people who ate 3 times the RDA of necessary protein. The participants exercised accordingly in order to lose an average of a couple of lbs each week. The medical experts established that people that ingested double were likely to drop pounds without decreasing muscle tissue even while training on the weight loss diet. The individuals who ingested triple the quantity of required protein didnt experience any further weight loss than the double group.
If ever youre wanting to burn fat, decreasing lean muscle is precisely what you shouldnt be working at, as muscle burns up extra calories and boosts metabolism. Whilst the group was small, this well-controlled study demonstrates that if youre healthy and active, upping your own protein intake while limiting over-all calories could be the best option for short-term fat loss, the researchers state, even though they note you should still adhere to a well-balanced diet in the long term.
The RDA of necessary protein differs subject to how much you weigh and how active you are, but as an example, the RDA for a 130-pound active individual is 77 grams, meaning in accordance with this investigation you need to strive for 144 grams of protein every day if you are wanting to get in shape.
