联合纵队

怎样的队伍才能称之为梦之队呢?狭义上的梦之队通常是指那支在1992年巴塞罗那夏季奥运会上最终夺得金牌的美国男子篮球队。如今俄罗斯女子网球队已经可以进入梦之队大军了,虽然她们没有网罗女子网坛所有的顶尖选手,但是她们是女子网坛最有深度,最不可战胜的整体。     

Diagnosis and Treatment of Foot Infections

The equine foot is a prime candidate for bacterial and fungal infections. The majority of infections are abscess based and generally are easily managed. Prolonged infections can result in chronic lameness and in severe cases they can be life threatening. A systematic approach to evaluation of the equine hoof can expedite the diagnosis and treatment of foot infections.

Future Veterinary Diagnostics

The development of rapid, accurate, and sensitive diagnostic methods for detecting pathogens is the basis for treating, controlling, and eradicating infectious diseases of veterinary importance. Scientific and technological advancements have revolutionized the field of veterinary diagnostics. Genome sequencing has allowed efficient, sensitive, and specific diagnostic assays to be developed based on the detection of nucleic acids. The integration of advances in biochemistry, proteomics, engineering, and medicine offers enormous potential for the rapid and accurate diagnosis of viral, microbial, genetic, and metabolic disease. In the future, polymerase chain reaction assays, microarray testing, genomic analysis, and metabolic profiling will be accomplished in a rapid, portable, sensitive, and cost-efficient manner.

Triggering a cell shape change by exploiting preexisting actomyosin contractions

Apical constriction changes cell shapes, driving critical morphogenetic events, including gastrulation in diverse organisms and neural tube closure in vertebrates. Apical constriction is thought to be triggered by contraction of apical actomyosin networks. We found that apical actomyosin contractions began before cell shape changes in both Caenorhabitis elegans and Drosophila. In C. elegans, actomyosin networks were initially dynamic, contracting and generating cortical tension without substantial shrinking of apical surfaces. Apical cell-cell contact zones and actomyosin only later moved increasingly in concert, with no detectable change in actomyosin dynamics or cortical tension. Thus, apical constriction appears to be triggered not by a change in cortical tension, but by dynamic linking of apical cell-cell contact zones to an already contractile apical cortex.
