Researchers develop label-free technique to image microtubules
Researchers label-free technique image microtubules
2017/2/16
Imaging very small materials takes not only great skill on the part of the microscopist, but also great instruments and techniques. For a refined microscopic look at biological materials, the challeng...
Leucine supplementation enhances integrative myofibrillar protein synthesis in free-living older men consuming lower- and higher-protein diets: a parallel-group crossover study
aging deuterated water dietary protein leucine muscle protein synthesis
2018/12/19
Background: Leucine co-ingestion with lower-protein (LP)–containing meals may overcome the blunted muscle protein synthetic response to food intake in the elderly but may be effective only in individu...

Some of the world’s most important discoveries – penicillin, vulcanized rubber and Velcro, to name a few – were made by accident. In fact, it’s been said that upward of half of all scientific discover...
A Thermodynamic Framework For Identifying Free Energy Inventories of Enzyme Catalytic Cycles
Steroid Isomerases Catalysis Hydrogen-Ion Concentration Thermodynamics Models, Chemical
2016/5/25
Pauling's suggestion that enzymes are complementary in structure to the activated complexes of the reactions they catalyze has provided the conceptual basis to explain how enzymes obtain their fantast...
Effects of Rice Bran, Flax Seed, and Sunflower Seed on Growth Performance, Carcass Characteristics, Fatty Acid Composition, Free Amino Acid and Peptide Contents, and Sensory Evaluations of Native Korean Cattle (Hanwoo)
Flax Seed Methionine Glutamic Acid α-Aminoadipic Acid Sensory Evaluations Hanwoo

This study was conducted to evaluate the effect of dietary supplementation with rice bran, flax seed, or sunflower seed to finishing native Korean cattle (Hanwoo) on growth performances, carcass chara...
Free 25-hydroxyvitamin D is low in obesity, but there are no adverse associations with bone health
bone density bone turnover half-life obesity vitamin D vitamin D–binding protein
2018/11/30
Background: The mechanism and clinical significance of low circulating 25-hydroxyvitamin D [25(OH)D] in obese people are unknown. Low total 25(OH)D may be due to low vitamin D–binding proteins (DBPs) ...
Whey protein, amino acids, and vitamin D supplementation with physical activity increases fat-free mass and strength, functionality, and quality of life and decreases inflammation in sarcopenic elderly
amino acids dietary supplement elderly insulin-like growth factor I fat-free mass relative skeletal muscle mass sarcopenia vitamin D whey protein
2018/11/28
Background: Interventions to attenuate the adverse effects of age-related loss of skeletal muscle and function include increased physical activity and nutritional supplementation.
Hippocampal Context Processing is Critical for Interference Free Recall of Odor Memories in Rats
hippocampus context interference
2015/8/7
Interference is a critical problem for memory systems and a primary cause of retrieval failure. One strategy for minimizing interference is to associate the items to be remembered with the context in ...
