Membrane trafficking and vesicle fusion

The functions of the eukaryotic cell rely onmembrane-bound compartments called organelles. Each of these possesses distinct membrane composition and unique function. In the 1970’s, during George Palade’s time, it was unclear how these organelles communicate with each other and perform their biological functions. The elegant research work of James E Rothman, Randy W Schekman and Thomas C Südhof identified the molecular machinery required for membrane trafficking, vesicle fusion and cargo delivery. Further, they also showed the importance of these processes for biological function. Their novel findings helped to explain several biological phenomena such as insulin secretion, neuron communication and other cellular activities. In addition, their work provided clues to cures for several neurological, immunological and metabolic disorders. This research work laid the foundation to the field of molecular cell biology and these post-Palade investigators were awarded the Nobel Prize in Physiology or Medicine in 2013.

关系数据库中关系模式的规范化

关系数据库中的关系模式直接影响了数据库中数据的完整性、准确性和一致性,好的关系模式能避免数据冗余和操作异常。关系规范化是设计关系模式的依据,是围绕函数依赖进行的。其基本思想是一个关系只描述一个主题,遵从"一事一地"原则,不能把彼此没有直接关联的属性放在一起,这将会导致关系数据库性能变坏。关系规范化过程是不断分解关系的过程。根据关系中属性间函数依赖情况规定了若干标准,这就是所谓的1NF、2NF和3NF,还有更高的范式,通常认为3NF在性能、扩展性和数据完整性方面都达到了最好的平衡,故一般关系模式设计要求达到3NF。     

转型时期图书馆知识产权管理战略需求、目标与路径

Association of hyperhomocysteinemia to alcohol withdrawal in chronic alcoholics

This study is conducted in chronic alcoholics to assess the association of an Individual’s level of serum homocysteine with the success of achieving alcohol deaddiction in the patient. The patients’ nutrition status is also assessed. 50 chronic alcoholics admitted to a deaddiction center were inducted into the study. Patients underwent an 8 weeks holistic program to promote rehabilitation from alcoholism. All the patients were addicted to alcohol for 8 – 10 years. Of the 50 patients enrolled, 39 of them completed the 8 weeks program including complete abstinence from alcohol during this period. Fasting blood samples were collected on admission and again after 8 weeks of alcohol abstinence for analyses of serum homocysteine and serum prealbumin, transferrin, total proteins and albumin, gammaglutamyl transferase (GGT) and alanine transaminase (ALT). Of the 50 patients enrolled in the study, 39 completed the 8 weeks rehabilitation program. 11 patients discontinued within 2 weeks of admission. During the 8 weeks of complete alcohol abstinence, patients were given a balanced diet and multivitamin supplements. A significant improvement in their nutritional status was noted by the elevation of serum levels of prealbumin, transferrin, total proteins and albumin. Serum homocysteine levels decreased significantly (p<0.002) to normal levels from previous hyperhomocytenemia. This was accompanied by decrease in serum GGT and ALT levels indicating improved liver functions. Serum estimation of homocysteine in chronic alcoholics is important to assess whether the patient will have a successful rehabilitation. Normal homocysteine levels are achieved after dietary changes and abstinence from alcohol. Timely correction of hyperhomocysteinemia also provides successful rehabilitation.     

关于我国钢铁工业发展的思考

1996年我国粗钢产量首次突破1亿吨,产量跃居当年的世界第一,在我国的冶金史上树立了一块里程碑,圆了多年国人要把中国变为钢铁大国的梦.最近三四年我国已经扭转了从建国以来就一直存在的钢铁供应紧缺的局面,供和需转为大体平衡,钢铁进一步增产的紧迫性已不如从前,但这并不等于市场对钢铁的需求不会随着国民经济的发展进一步增长,事实上,尽管这几年钢铁的供需矛盾趋于缓和,但无论需求和生产仍是逐年增长的,只是增长的幅度不如前几年大.在面临世纪之交,对我国钢铁工业的发展进行分析,找出未来发展的方向是非常必要的.     

New age adjuvants and delivery systems for subunit vaccines

The dramatic advancements in the field of vaccinology has led to the formulation of chemically well defined vaccines composed of synthetic peptides and recombinant proteins derived from the immunologically dominant regions of the pathogens. Though these subunit vaccines are safer compared to the traditional vaccines they are known to be poorly immunogenic. This necessitates the use of adjuvants to enhance the immunogenicity of these vaccine formulations. The most common adjuvant for human use is alum. Research in the past has focused on the development of systemic immunity using conventional immunization protocols. In the present are, the emphasis is on the development and formulation of alternative adjuvants and delivery systems in generating systemic as well as mucosal immunity. This review mainly focuses on a variety of adjuvants (particulate as well as non-particulate) used with protective antigens of HIV, malaria, plague, leprosy using modified delivery vehicles. The experience of our laboratory and other researchers in this field clearly proves that these new age adjuvants and delivery systems undoubtedly generate enhanced immune response-both humoral and cell mediated. The choice of antigens, the nature of adjuvant used and the mode of delivery employed have a profound effect on the type of immune response generated. Besides the quantity, the quality of the antibodies generated also play a vital role in protection against these diseases. Some of the adjuvants and delivery systems used promoted high titre and affinity antibodies, which were shown to be cytophilic in nature, an important criteria in providing protection to the host. Thus the studies on these adjuvants/delivery systems with respect to various infectious diseases indicate their active role in efficient modulation of immune response along with safety and permissibility.
