Brain damage sustained from repeated blows in boxing, wrestling, and other combat sports has serious physical and mental health consequences. The degenerative brain disease, chronic traumatic encephalopathy (CTE), presents clinically with memory loss, aggression, difficulty in rational thinking and other cognitive problems. This spectrum, which mimics Alzheimer’s disease, is diagnosed post-mortem through a brain biopsy in many professional athletes. However, little is known about the process of development and how to identify vulnerable individuals who may be on course for developing CTE. Boxing is a sport that has a severe toll on athletes’ health, primarily on their brain health and function. This review addresses the concerns of brain injury, describes the pathologies that manifest in multiple scales, e.g., molecular and cognitive, and also proposes possible diagnostic and prognostic markers to characterize the early onset of CTE along with the aim to identify a starting point for future precautions and interventions.

结肠息肉的冷套扎切除

世界核心医学期刊文摘（胃肠病学分册） 2005年第11期1卷 45-45页

作者： Deenadayalu V.P. rex D.K. 陈云茹 Indiana University Hospital # 4100 550 N. University Blvd Indianapolis IN 46202 United States Dr.

Background: The removal of small colon polyps by cold snare transection without electrocautery effectively eliminates polyps, and anecdotal reports indicate a lowrisk of bleeding and perforation. Concerns about using cold snaring have centered on the risk of immediate bleeding and the difficulty in retrieving the polyp. The objective was to determine the retrieval rates of polyps after cold snaring after two different methods of resection and retrieval. Methods: Consecutive polyps were identified by a single colonoscopist who chose the technique of polypectomy (hot snare, cold snare, or cold forceps). If cold snaring was chosen, an independent observer assigned the polyp to method A (cold resection of polyp without tenting and then suction of the transected polyp into a trap) or method B (ensnare the polyp, pull it into the colonoscope channel, and then transect it while suctioning). The size and the approximate location of all polyps were recorded and all collected specimens were sent separately for histologic examination. Results: Of 519 consecutively encountered polyps, 400 were removed by cold snare: 197 were assigned to method A and 203 to method B. The mean size of polyps that were cold snared was 3.5 mm. The mean time to remove and to retrieve polyps with method A was 14.5 seconds (n = 58) and with method B was 18.1 seconds (n = 60) (p = 0.03). There were no complications from cold snaring. The rate of successful retrieval with method A was 100% (197 of 197 polyps) and with method B was 98% (199 of 203 polyps) (p = 0.04). Conclusions: Cold snare remov-al of colon polyps is associated with a high polyp retrieval rate. Each of two methods of polyp retrieval was effective. Snare transection without tenting of the polyp, followed by suctioning of the specimen off the polyp site, was more efficient, though the difference in efficiency was minimal. Difficulty or failure to retrieve polyps should not be a concern with regard to cold snare polypectomy.

Plugs are crucial for initiating crop production in greenhouses, soil, and controlled environment agriculture (CEA). Vegetable, fruiting, ornamental, and other horticultural crops that utilize plugs for production have demonstrated superior transplant establishment rate, plant health, and total yield. The APS laboratory for Sustainable Food at Florida Gulf Coast University investigated the quality of plugs grown based on different concentrations and fertigation sources using synthetic and organic sources. We carried out the growth of “rex Butterhead” lettuce (latuca sativa) plugs with five different fertigation treatments, 1) full-strength synthetic starter fertilizer solution;2) half-strength synthetic starter fertilizer solution;3) full-strength organic starter fertilizer solution;4) half-strength organic starter fertilizer solution, and 5) no fertilizer for control. Fertilizer treatments were formulated following manufacturer recommendations. The seeds were sown in Oasis® Horticubes and saturated every day with the different fertilizer treatments. The plugs were cultivated for 15 days in a controlled environment until two leaves after the cotyledons had developed. After 15 days, we collected data which included wet weight (g), dry weight (g), leaf area (cm2), and chlorophyll concentration (mg/cm2). In addition, we derived data including the leaf Area Index (lAI, cm2/cm2) and Specific leaf Area (SlA, cm2/g). Descriptive statistics were used to describe the biomass data. A Tukey’s HSD test was carried out to understand the differences between the fertilizer sources. We determined there was a statistically significant difference (P = 7.34E−29) in the measured plug growth parameters due to the various fertigation sources. We found that all fertilizer treatments produced viable plugs except for the control treatment. Of all the treatments, we concluded the half-strength organic treatment produced the mo

为了了解紧密纺普梳纱与传统环锭纺精梳纱成纱性能的差异,在相同配棉、相同开清和梳棉工艺、同一粗纱定量条件下,利用DTM129型细纱机纺制了CJ 14.5 tex精梳纱,并加装Suessen公司E lite紧密纺装置纺制了C 14.5 tex普梳纱。通过测试对比两品种的成纱性能,结果表明:C 14.5 tex紧密纺普梳纱成纱细节、粗节和棉结指标较CJ 14.5 tex传统环锭纱差一些,但强伸性能指标较好,毛羽较少。生产中可通过加大梳棉落棉率等措施改善紧密纺普梳纱粗细节。认为紧密纺采用普梳工艺流程,相对于传统环锭纺精梳流程生产效率提高,在满足成纱质量要求的情况下紧密纺采用普梳纺纱工艺可降低生产成本。
