前不久,在哈维·阿隆索率领勒沃库森队史首次加冕德甲冠军后,我看到了一个有趣的数据统计。即所有转型成为主教练的退役球员中,有42%的人在球员时代踢的是中场的位置,而这其中后腰位置的球员又占据了大多数。同样是踢球,为什么中场和后腰能够产出更多的名帅?球员时期同样踢后腰,去年率曼城夺得三冠王的瓜迪奥拉给出了这样的解答,“当你是一名前锋,主要考虑的事情就是进球。但当你是一名中场,必须随时知道整个球场上发生着什么,自己的位置应该在哪里,这些会让你对比赛有着更多的了解。”

Hexoses accumulate to high concentrations （-200 mM） in storage parenchyma cells of tomato fruit. Hexoses are sourced from the fruit apoplasm as hydrolysis products of phloem-imported sucrose. Three hexose transporters （LeHT1, LeHT2, LeHT3）, expressed in fruit storage parenchyma ceils, may contribute to hexose uptake by these cells. An analysis of their full-length sequences demonstrated that all three transporters belong to the STP subfamily of monosaccharide transporters that localize to plasma membranes. Heterologous expression of LeHT1 （and previously LeHT2, Gear et al., 2000）, but not LeHT3, rescued a hexose transportimpaired yeast mutant w.en raised on glucose or fructose as the sole carbon source. Biochemically, LeHT1, similarly to LeHT2, exhibited transport properties consistent w.th a high- affinity glucose/H^＋ symporter. Significantly, LeHT1 and LeHT2 also functioned as low.affinity fructose/H^＋ symporters w.th apparent Km values commensurate w.th those of fruit tissues. A substantial reduction （80-90%） in fruit expression levels of all LeHT genes by RNAi-mediated knockdow. caused a 55% decrease in fruit hexose accumulation. In contrast, photoassimilate production by source leaves and phloem transport capacity to fruit w.re unaffected by transporter knockdow.. Collectively, these findings demonstrate that LeHTs play key roles in driving accumulation of hexoses into storage parenchyma cells during tomato fruit development.

This paper provides an analytical approach to determine the optimum pitch by utilizing a thermal resistance netw.rk, under the assumption of constant luminous efficiency. This w.rk allow. an LED array design w.ich is mounted on a printed circuit board （PCB） attached w.th a heat sink subject to the natural convection cooling. Being validated by finite element （FE） models, the current approach can be show. as an effective method for the determination of optimal component spacing in an LED array assembly for SSL.

A potency-enhanced polyanionic phyto-saccharide of elm mucilage (PEPPS) w.s prescribed by 197 small animal veterinarians in an open-labeled field trial. Clients provided informed consent to veterinarians to prescribe PEPPS to 3952 dogs and 2248 cats. A 2 day/4 dose response rate, determined by veterinarians’ consensus, provided clinical threshold for a significant clinical outcome. Data w.s collected through phone interview. conducted over a period of 3.5 years from June 2003 through December 2006. 82% of 1928 vomiting dogs and 77% of 1064 vomiting cats responded to PEPPS w.thin 2 days or four doses. 93% of 2024 dogs and 79% of 1184 cats w.th diarrhea responded to PEPPS w.thin 2 days or four doses. PEPPS appears useful for managing vomiting and diarrhea in dogs and cats. How.ver, a randomized blinded placebo controlled trial is needed to quantify true clinical efficacy.
