The main objective of.this work was to update the data on the epidemiological, clinical, etiological and prognostic aspects of.these acute upper digestive hemorrhages. It was a prospective study f.r a period of.11 months (f.om March 2013 to January 2014) at the digestive endoscopy center of.Gabriel Touré University Hospital in Bamako. At the end of.this study, 63 patients had acute upper digestive bleeding (AUDB) among 954 hospitalized patients, that is to say a f.equency of.6.7%. The sex ratio was 3.5. The average age of.our patients was 45 ± 16.57 years with extremes of.15 and 84 years. A notion of.smoking, epigastralgia and none steroid anti-inf.ammatory drugs (NSAIDs) were more reported in the history with respectively 14 patients (22.3%), 10 patients (15.9%) and 4 patients (6.3%), but haematemesis had occurred in 24 (38.1%) patients without any antecedent. The main causes of.hemorrhage were rupture of.oesophageal varices in 34 (57.6%) patients and peptic ulcers in 18 (30.5%) patients. Early recurrence occurred in 7 (11.1%) patients resulting in the death of.5 patients f.r an overall mortality of.9 patients among 63 (14.3%). Acute high digestive hemorrhages are always serious. The correct management of.the hemorrhagic episode by haemostatic gestures when available and the causes of.haemorrhage improve the prognosis.

法兰西第三共和国之前的司法官职业,并没有为这个国家法律和权利的保护提供足够的保障,其中最优秀的司法官迷失在了对无穷无尽的司法官衔的追逐之中,而被寄予厚望的法兰西第三共和国仍然没能终结这一现状,司法官们一味追求晋升,使得政府实现了对司法的控制,司法俨然成为政治报复和政治奖励的机器,司法理想所委以重任的法官和检察官的廉洁性和公正性逐渐丧失,司法行政化、官僚化得以形成和加强。法兰西第三共和国期间的司法官晋升实践的历史,有助于阐明司法管理体制对司法权异化的因果关系:为什么曾经承诺要实现理想的共和国司法,堕落为逆淘汰的、毫无生气的官僚机构?司法管理和法官晋升的垂直模式,对司法权运行规则之破坏和对司法权之异化为类行政权,潜移默化地产生了何种决定性作用?吸取这一沉痛的历史教训,有助于司法改革在法官晋升模式和司法体制管理方面,避免在去地方化的同时陷入另一个更可怕的司法行政化深渊。

Af.ican indigenous vegetables have many nutritional and health benef.ts that have not been well researched and f.lly exploited. The objective of.this study was to determine iron and protein contents of.seven priority Af.ican indigenous vegetables f.und in Eastern Af.ica. The vegetables were planted at two sites, Maseno University, Maseno in western Kenya and Jomo Kenyatta University of.Agriculture and Technology （JKUAT）, Juja in Central Kenya between 2006 and 2008. These vegetables were organically grown and edible parts of.each of.the vegetable harvested during vegetative growth stages just bef.re onset of.f.owering and analysed f.r iron and protein contents. Nightshade and cowpea had high levels of.both iron and protein. Pumpkin leaves and amaranths had high iron content while spiderplant and slenderleaf.had high protein levels. Both iron and protein levels dif.ered signif.cantly between the seven vegetables at both sites. Nightshade and cowpea contained iron and protein levels that would provide 100% of.the recommended daily allowance （RDA） iron and 50% of.recommended daily allowance protein f.r optimal human growth and health. These results help to demonstrate the nutritional value of.Af.ican indigenous vegetables and their potential use in nutrition intervention programs.

In the past 20-30 years, developmental biologists have made tremendous progress in identif.ing genes required f.r the specif.ca-tion of.individual cell types of.an organ and in describing how they interact in genetic networks. In comparison, very little is known about the mechanisms that regulate tissue polarity and overall organ patterning. Gynoecia and f.uits f.om members of.the Brassicaceae f.mily of.f.owering plants provide excellent model systems to study organ patterning and tissue specif.cation because they become partitioned into distinct domains whose f.rmation is determined by polarity establishment both at a cellular and whole tissue level. Interactions among key regulators of.Arabidopsis gynoecium and f.uit development have revealed a network of.upstream transcription f.ctor activities required f.r such tissue dif.erentiation. Regulation of.the plant hormone auxin is emerging as both an immediate downstream output and input of.these activities, and here we aim to provide an overview of.the current knowledge regarding the link between auxin and f.male reproductive development in plants. In this review, we will also demonstrate how available data can be exploited in a mathematical modeling approach to reveal and understand the f.edback regulatory circuits that underpin the polarity establishment, necessary to guide auxin f.ows.

The uppermost part of.the Upper Bathonian Sponge Limestone member, Patcham f.rmation, of.the Jhura Dome of.Kachchh Mainland is a thickening-and shallowing-upward succession topped by medium-to thick-bedded hummocky cross-stratif.ed grainstones deposited by storm waves. Occasionally, thin, commonly lenticular, intraclastic-bioclastic silty marl intercalations between the grainstones are highly bioturbated, in contrast to the grainstones, in which, f.r the most part, trace f.ssils occur scattered. Large exposures of.bedding planes of.the grainstones allow the detailed investigation of.ichnological f.atures, whereas the high density of.traces in the sof. marls precludes the identif.cation of.any ichnotaxa. Eighteen ichnotaxa have been recorded including Ophiomorpha, Thalassinoides, Taenidium, Gyrophyllites, Chondrites, Dactyloidites, Teichichnus, Bolonia, and Ancorichnus. Except f.r Ophiomorpha nodosa and Thalassinoides, which generally indicate moderate to high energy conditions and are the dwelling burrows of.suspension-f.eding to omnivorous crustaceans, the ichnotaxa represent a deposit-f.eding behaviour of.their producers and thus are characteristic of.low-energy environments. The trace f.ssils f.rm three ichnoassemblages characterized by(1) Ophiomorpha nodosa and Thalassinoides suevicus,(2)?Thalassinoides isp. A, Taenidium, and Bolonia lata,and(3) Ancorichnus. The dominance of.traces of.deposit-f.eders in rocks indicative of.high-energy events is counterintuitive and points to their non-contemporaneity. The sediments were deposited during brief.highenergy events, whereas the trace f.ssils were produced when, af.er waning of.storms low-energy conditions prevailed. This time-averaging is particularly pronounced in trace f.ssils that extend vertically downwards and may reach strata deposited under distinctly dif.erent conditions. Thus, environmental interpretations based on trace f.ssils should ref.r to colonisation surf.ces rather than to the sediment surrounding th
