Bone wound healing is a highly dynamic and precisely controlled process through which damaged bone undergoes repair and complete regeneration. External factors can alter this process, leading to delayed or failed bone wound healing. The findings of recent studies suggest that the use of selective serotonin reuptake inhibitors(SSRIs) can reduce bone mass, precipitate osteoporotic fractures and increase the rate of dental implant failure. With 10% of Americans prescribed antidepressants, the potential of SSRIs to impair bone healing may adversely affect millions of patients’ ability to heal after sustaining trauma. Here, we investigate the effect of the SSRI sertraline on bone healing through pre-treatment with(10 mg·kg-1sertraline in drinking water, n = 26) or without(control, n = 30) SSRI followed by the creation of a 5-mm calvarial defect. Animals were randomized into three surgical groups:(a) empty/sham,(b) implanted with a dermaMatrix scaffold soak-loaded with sterile PBS or(c) dermaMatrix soak-loaded with542.5 ng BMP2. SSRI exposure continued until sacrifice in the exposed groups at 4 weeks after surgery. Sertraline exposure resulted in decreased bone healing with significant decreases in trabecular thickness, trabecular number and osteoclast dysfunction while significantly increasing mature collagen fiber formation. These findings indicate that sertraline exposure can impair bone wound healing through disruption of bone repair and regeneration while promoting or defaulting to scar formation within the defect site.

A brief account of our studies on the hurricane forecast problem is presented here. This covers recent prediction results from the Florida State University (FSU) regional and global numerical weather prediction models. The regions covered are the Indian and the Pacific Oceans. The life cycle of the onset vortex (a hurricane) of the summer monsoon, typhoons over the western Pacific Ocean and tropical cyclones over the Bay of Bengal (Andhra Pradesh and the Bangladesh storms) are covered here. The essential elements in the storm formaton are the strong horizontal shear in the cyclogenetic areas, a lack of vertical shear and warn sea surface temperatures. The storm motion has a steering component largely described by the advection of vorticity by a vertically averaged layer mean wind, the recurvature of a storm appears to invoke physical processes via the advection of divergence by the divergent part of the wind especially in the outflow layers of the storm. Very high resolution global models seem to be able to handle the motion and structure during the entire life of typhoons quite reasonably. The scope for better diagnosis of the storms life cycle appears very promising in view of the realistic simulation of the life cycle.

为有效地利用cray-1计算机,我们提出了某些适用于模型问题块迭代法的收敛速度的分析法。其中一种有趣方法是P×P个点块的松弛法。Cholesky分解用于较小型的问题。其主要的一种分析法是修改早期Parter讨论过的方法。该分析法易于扩展用于更为普遍的二阶椭园问题。在解很大的线性代数方程组时,人们经常要考虑一些“迭代方法”。在这些方法中,人们要选取第一次估计值,比如说U0,然后逐次计算其它估算值U2,U2,…。关于这种方法的主要问题是: 1.这种方法可行吗?即,假如我能完成这个过程的运算,那么UR是否接近于真正的答数U呢? 2.采用这种方法的花费划算吗?即,如果我能估算出每一次迭代的开支,那么需要进行多少次迭代才能使初始误差|U-U0|降低某一固定的小倍数,比如δ。上述两问题要通过与迭代法有关的量ρ的计算来解决。本报告讨论了解重要二阶椭园偏微分方程问题中某些获得ρ的理想近似估算方法。
