Eastern oyster (Crassostrea virginica) abundance has declined severely over the past century along the Atlantic and Gulf coasts of the United States. For varied reasons, overfishing among the foremost, bivalves no longer make up considerable reefs as was common. While discourse continues on oyster restoration and augmentation, gaps in knowledge of C. virginica and regional environmental interactions remain. Our primary aim was to examine the C. virginica filter feeding of phytoplankton in the Hudson River Estuary, New York City. Secondarily, this study examined the filtration of these oysters in relation to environmental attributes. Chlorophyll-a, the predominant photosynthesizing pigment in red and green algae, is an indicator of phytoplankton productivity in aquatic settings. Crassostrea virginica consumes first-tier plankton from the water column’s seston;thus analysis of chlorophyll-a content allows estimating phytoplankton concentrations, from which oyster filtration efficiency (FE) was quantified. Water conditions (temperature, dissolved oxygen, pH, salinity, turbidity, tide and flow rate) also were recorded. Spectrophotometric determination of chlorophyll-a concentration methodology was derived from the Standard Methods text favored by the US EPA. This project compared real-time Hudson River Estuary (HRE) water samples prior to passing through a contained oyster reef and samples of water post-filtration. This sampling scenario was unique as the contained reef used was fed by HRE water. Most studies on oyster filtration have been laboratory-based, and few assessed oysters in the field. This study took place at Pier 40, the River Project Wetlab, lower Hudson River along Manhattan. The FE of this reef was calculated for two months during various environmental states which can be the basis of future investigations. Statistically significant differences were found between pre- and post-filtration water samples (Z = 4.620, p < 0.001). This study provides a glimpse

Amoxicillin/clavulanate is associated with liver injury, mostly of a cholestatic pattern. While outcomes are usually benign, progression to cirrhosis and death has been reported. The role of immunosuppressive therapy for patients with a protracted course is unclear. We report the case of an elderly patient who developed prolonged cholestasis secondary to amoxicillin/clavulanate. Vanishing bile duct syndrome was confirmed by sequential liver biopsies. The patient responded to prednisone treatment, but could not be weaned off corticosteroids, even when azathioprine was added. Complete withdrawal of both prednisone and azathioprine was possible by using mycophenolate mofetil, an inosine monophosphate dehydrogenase inhibitor. Sustained remission has been maintained for more than 3 years with low-dose mycophenolate mofetil.

With the prediction of climate change-induced increases in drought frequency and severity in the southeastern USA, it is important to better understand the risks that drought may pose to NO3 accumulation in bermudagrass [Cynodon dactylon (L.) Pers.] forage. This report offers observations of NO3 concentration in Bermudagrass forage samples submitted to the University of Georgia’s Feed and Environmental Water Lab (FEWL) during the extreme to exceptional drought of 2007, the severe drought of 2008, and the four preceding seasons when drought stress was minimal or absent. The probability (P) of a sample being at high risk for nitrate toxicosis was the greatest for the extreme to exceptional drought of 2007 (P = 0.160), slightly lower in the severe drought year of 2008 (P = 0.105), and the lowest for samples from the 2003-2006 growing seasons (P = 0.082) when drought stress was minimal or absent.

大容量并行处理机除应用于解决三维叠前深度偏移问题之外,目前还用来降低不太复杂的目的在于进行剩余速度分析的三维叠前时间偏移和三维叠后深度偏移问题的整个运算时间。许多研究人员强调的显式褶积技术,在大多数MPP中所用的标量处理机上运行有很高的失败率。本文讨论两种共炮检距时间偏移和一种叠后深度偏移在Cray T3D并行机上的实施过程。每种方法都努力在保持详细的速度模型和陡倾角的高成象精度的同时尽可能快地完成。为此应用了多种并行和标量优化算法以获得这些算法的高性能,同时在各处理机之间合理地均衡分配工作量。

提高HA涂层的晶体含量能够使得它们在体内的耐降解能力比低结晶度的HA涂层高很多,但更高的结晶度也降低了表面可浸润性,这可能对组织附着和长期临床结果有不利的影响。本前瞻性研究的开展是为了确定在之前报道的浸润性降低的前提下,是否高结晶度HA涂层种植体能够符合最低85%的5年种植体成功率标准。研究对象是在3家大学牙科诊所和1家私人牙科诊所就诊,上颌和/或下颌有1或多个缺失牙齿的连续病人,共有120位病人按方案进行了治疗并且成功的用种植体支持修复体进行了修复。3位病人的4个种植体失败并从此研究中排除。没有出现其他无法解决的不良事件。5年时的累积成功率是97%(n=88位病人的184个种植体),超过了5年临床使用后种植体成功率85%的标准。
