玉米深加工热的冷思考

近年来，玉米加工转化能力的年增长率在20％左右，带来了当前玉米加工业的扩张加工的产品包括玉米油、燃料乙醇、变性淀粉、淀粉糖、赖氨酸、生态塑料、柠檬酸等，与国际市场比，我国玉米加工产品专用品种少、技术含量低、企业规模偏小，综合加工能力弱。     

在竞争中求发展在和谐中求共赢

在全球经济一体化、信息资讯透明度、以及产品同质化的程度越来越高的今天,激烈的市场竞争无处不在,最典型的是很多的人还是挥舞着低价竞争这把双刃剑在到处砍杀,既伤了别人也伤了自己.……     

Changes in the mucosa of the small intestine in white rats in the process of digestion

Morphological and morphometric studies of the small intestine of albino rats have shown that its villi undergo cyclic changes. These changes involve the death, growth and maturation of the villi. Digestion intensifies proliferative processes in the small intestinal mucosa. The data obtained support the conception that the death of the villi is a morphological expression of secretion (excretion) and absorption in the small intestine.     

世界主要产棉国标准对比分析

基于不同国家在种植、生产、气候、文化环境方面的差异,世界上主要产棉国棉花标准也存在差异性;而棉花物理性能本身和全球一体化棉花交易规则决定了棉花标准在很多方面必须是相同或相近的。为了有效地管理棉花质量和控制棉花标准,达到或趋近一个公平交易原则,为了优化国际棉花采购,比较并控制混配棉及棉花、棉纱的质量,介绍了棉花标准制定的意义,多方面分析了美国与中国细绒棉质量标准存在的异同点以及两国细绒棉标准发展的趋势,比较了主要长绒棉生产国棉花现行标准的异同点,为未来世界棉花标准制定达成共识提供了基础保证,为全世界棉花贸易纠纷有效处理提供了仲裁依据,有利于促进全世界棉花质量的改进和提高。

Age-associated changes in the amount of subcutaneous tissue in the face evaluated in the ultrasonic B mode

In this study, age-associated changes in facial skin, cosmetologically critical factors, were studied in terms of local subcutaneous fat tissue. The subjects were 98 Japanese females evenly chosen from their teens to 70s. On each subject, the thickness of subcutaneous tissue was determined by the ultrasonic B mode method on four facial sites, forehead, orbit, cheek, and mandible. Age-association of the tissue thickness was facial site-dependent. In the orbit, the subcutaneous tissue became thicker with age, whereas it showed a tendency of thinning in the forehead. No clear age-association was observed in the cheek or the mandible. To analyze the age-association further, the data were stratified into 'lean group' and 'obese group' based on their BMI, and subjected to multiple regression analysis. The age-association in the orbit was much more distinctive in the lean group than in the obese group.

Changes in major proteins in the embryonic capsule during immobilization (fixation) of the conceptus in the third week of pregnancy in the mare

During the third week of pregnancy, the equine conceptus is enclosed within a capsule, the glycan composition of which changes at around day 16 (ovulation = day 0) when the conceptus becomes immobilized (fixed) in the uterine lumen. Our objective was to characterize the process of fixation by identifying changes in major capsule-associated proteins. Individual equine conceptuses (n = 55) were collected transcervically by uterine lavage between days 13.5 and 26.5. Major proteins extracted from capsules were compared with those in fluids from the uterus and yolk sac by SDS-PAGE. Until day 14, a major capsule-associated protein that migrated at approximately 10 kDa was identified by N-terminal sequencing as equine beta2 microglobulin (beta2M). During fixation, beta2M in the capsule underwent limited proteolysis to an approximately 8 kDa form lacking nine amino acids from the N terminus, and was subsequently degraded. Expression of beta2M mRNA was detected in the yolk-sac wall tissues and endometrium between days 13.5 and 17.5. During this period, beta2M in the capsule was evidently not part of a complex with major histocompatibility complex class 1 heavy alpha chain bands because these were undetectable in the capsule and uterine lavage. Uterocalin (p19) was detected in uterine lavage and capsule throughout fixation, but in yolk-sac fluid only before fixation. These studies indicate that intact beta2M is a major protein associated with the embryonic capsule before fixation, after which it undergoes limited proteolysis to a truncated approximately 8 kDa form that remains in the capsule after the conceptus is immobilized.
