Under the prospective payment system (PPS), designated sole community hospitals (SCH's), usually smaller than other rural hospitals but offering comparable services, have had higher average cost levels, in part because of underutilization of plant and equipment. This has resulted in negative operating margins on patient revenues, although local financial support and other revenue sources bring ...

Introduction 0.1. Let X be a scheme, reduced and separated, of finite type over Z. For p a prime number, one may consider the set X(Z p) of its Z p-rational points. For every n in N, there is a natural map π n : X(Z p) → X(Z/p n+1) assigning to a Z p-rational point its class modulo p n+1. The image Y n,p of X(Z p) by π n is exactly the set of Z/p n+1-rational points which can be lifted to Z p-r...

1 .1 直肠肛门抑制反射 正常生理情况下 , 直肠扩 张由大脑皮层控制 , 在粪便通过直肠引起直肠扩张 后引起 肛 门内 括 约肌 ( in ternu s anal sphincter , IAS) 反射性舒张。Pfefferkorn 等 [ 1 ] 报道 80 例儿童 在全 麻状 态下 仍然 能测 出直 肠肛 门抑 制反 射 ( rectanal inhibitory reflex , RAIR ) , 由此可推 测 RAIR 可能是低级反射中枢完成的。在一般情况 下 , RAIR 都能测出。国内外目前的标准尚不统一 , 但一般认为气囊 50 ml 仍不能引出 RAIR , 看作 RAIR 消失 ;若 30 ml≤气囊≤50 ml 看作 RAIR 减 弱。在以下 病理情 况下 , RAIR 可 消失 或减弱 : (1 )先天性巨结肠 ( Hirschsprung’s disea...

J Nippon Med Sch 2008; 75 (1) Fig. 1 Diferent concentrations of VEGF generates diferent structures of the vasculature. HUVECs cultured on Cytodex3 beads were embedded in fibrin gel. In the presence of 15.0 or 2.5ng/mL VEGF, HUVEC / Cytodex3 beads were cultured for 7 days. Images were captured with an Olympus IX71 microscope with a×4 objective lens.

A novel nucleoside antibiotic, Sch 36605, has been isolated from the culture filtrate of a Streptomycete sp.;°. All the physico-chemical and spectroscopic data presented herein indicate this compoundis a new blasticidin compound. A second closely related component, Sch 36606, was isolated0 together with Sch 36605. This compoundhas been characterized and identified as leucylblasticidin S2). Sch ...

Pyogenic granuloma (lobular capillary hemangioma) is a common reactive tumour-like lesion of the oral cavity arising in response to various stimuli such as chronic local irritation, drug intake, and hormonal changes. The clinical features are similar other lesions peripheral giant cell (PGCG) therefore definitive diagnosis depends on histopathologic evaluation. We report case three-year-old Ind...

Many studies have shown that women are under-represented in tenured ranks in the sciences. We evaluate whether gender differences in the likelihood of obtaining a tenure track job, promotion to tenure, and promotion to full professor explain these facts using the 1973-2001 Survey of Doctorate Recipients. We find that women are less likely to take tenure track positions in science, but the gende...
