Bimatoprost (lUMIGAN) is a novel synthetic prostamide that potently lowers intraocular pressure in dogs, primates and humans. Bimatoprost is functionally and pharmacologically distinct from PGF2alpha, potently exhibits prostamide-like activities and works directly to lower IOP. In this series of studies, confocal fluorescence microscopy was employed to compare the effects

First-year seedling survival impacts all subsequent management planning in plantation forestry. Descriptive statistics of first-year seedling survival data from the louisiana Department of Agriculture and Forestry (lDAF) indicated that survival success reaches a plateau at between 79% - 85% under normal weather conditions. We provide an explanation for this plateau based on an analysis of seedling and microsite qualities involved in operational pine plantations by: 1) using a conceptual model demonstrating how variation in seedling quality and microsite quality interact to determine plantation survival, 2) presenting an example to characterize quality distributions of seedling and microsite qualities, and 3) comparing model outcomes based on measured distributions to realistic values of first-year survival. Simulation results indicated that consistent survival could result from random pairings of initial seedling and site quality distributions. lDAF data analysis indicated that 72% of seedlings were associated with the most frequent quality class that comprised seedlings with stem caliper between 3.2 to 4.7 mm and average stem height and volume of 25.75 cm and 3.43 cm3, respectively. Similarly, assessment of microsites at planting sites in Southeast louisiana indicated that 48% of planted seedlings were associated with the most frequent microsite quality class which supported first-year height increment between 9 to 29 cm. Modelling of current operational practice indicated that using seedlings with larger caliper size would increase first year survival, but would result in higher establishment costs. The conceptual model could be modified to for use in other regions regardless of species types involved.

Purpose: The oxidative stress (OS) hypothesis of overtraining syndrome argues that increased production of free radicals through exercise cause muscle fatigue and damage resulting in lower athletic performance. Several studies have investigated OS immediately before and after exercise bouts in a training macrocycle. Our study aimed to compare OS of endurance athletes between a competition macrocycle and the immediate post-season recovery macrocycle. In addition, we aimed to identify athletes who experienced an unexplainable drop in athletic performance during the competition season in order to compare their OS to those who experienced no drop in performance. Methods: Fifteen members of the University of Alaska Fairbanks cross country ski team volunteered for this study. Blood samples were taken in early February (“mid-season”) and late April (“post-season”). Participants completed questionnaires regarding physical activity and athletic performance at the time of the blood draws. Plasma was analyzed for 4-hydroxynonenal (HNE), nitrotyrosine, nitric oxide (NOX), and superoxide dismutase (SOD). Significance was determined by Wilcoxon and Mann-Whitney tests. Results: Participants displayed significantly higher (p Conclusion: Signs of oxidative stress and mitigation during the post-season recovery macrocycle were higher in athletes who reported experiencing a drop in athletic performance during the competition season macrocycle.

得克萨斯西南部的瓦尔沃德盆地当前一个最重要的勘探目标是沿奥奇塔(Ouachita)前山带前缘分布的逆冲的宾夕法尼亚系(德莫因期)碳酸盐岩。这些储层从裂缝性石灰岩中产出高产天然气及凝析油,储层沉积在多变的环境中,以后在逆冲作用时期形成复杂的并置。地震图象能力的改进,特别是随着二维测带(2—D Swath)和三维勘探的引进,可以作出逆冲带前缘的精确图幅,以及修订盆地构造史的解释成果。这些数据明确地显示出不同构造部位多储层的存在,本文讨论涉及特里尔(Terrell)县西北帕金哈姆气田区的斯特朗储层。
