万建民 水稻褐飞虱 基因
2023/10/28
褐飞虱是水稻生产中最严重的害虫。褐飞虱通过针状口器刺入水稻叶鞘组织吸食韧皮部汁液，造成水稻严重减产甚至绝收。种植抗性品种是综合防控褐飞虱的基础。然而植物抗病虫性通常受光照、温度和湿度等环境因素的影响，在一定程度上制约了抗性基因的有效利用。如采用密植的栽培方式是当前许多作物增加单位面积产量的重要途径，但是密植通常会导致冠层以下的植株部分光照不足而产生庇荫反应，易滋生各类病虫害，虽然这种现象普遍存在，...

Anabolic sensitivity of postprandial muscle protein synthesis to the ingestion of a protein-dense food is reduced in overweight and obese young adults
insulin resistance leucine muscle mass inflammation amino acid transporters mTORC1
2018/12/14
Background: Excess body fat diminishes muscle protein synthesis rates in response to hyperinsulinemic-hyperaminoacidemic clamps. However, muscle protein synthetic responses after the ingestion of a pr...

High intake of regular-fat cheese compared with reduced-fat cheese does not affect LDL cholesterol or risk markers of the metabolic syndrome: a randomized controlled trial
saturated fat dairy triglycerides insulin glucose blood lipids
2018/12/14
Background: Regular-fat cheese contains a high amount of saturated fat. Therefore, dietary guidelines in many countries recommend the consumption of reduced-fat cheese as opposed to regular-fat cheese...

Exercise-induced muscle damage is reduced in resistance-trained males by branched chain amino acids: a randomized, double-blind, placebo controlled study
Recovery, BCAA Muscle damage Resistance training
2015/7/23
It is well documented that exercise-induced muscle damage (EIMD) decreases muscle function and
causes soreness and discomfort. Branched-chain amino acid (BCAA) supplementation has been shown to incre...
Blame smartphone alerts, constant connectivity and a deluge of media for our society’s sleep deprivation. But the root cause of why we get less sleep now than our ancestors did could come down to a mu...
