Objective: The purpose of this study was to monitor the introduction of the STAN-methodology(Noventa Medical, Moelndal, Sweden). Study design: This was a prospective observational study covering the total population of deliveries at term during 2 years. Four thousand eight hundred and thirty out of 14,687 term pregnancies were monitored using the STAN S 21 fetal heart monitor and the associated clinical guidelines. Cord artery metabolic acidosis, neonatal outcome, and rates of operative deliveries for fetal distress were assessed. Results: The annual rate of STAN usage increased from 28.1%to 37.7%and was associated with a significant reduction in metabolic acidosis rate in the total population from 0.76%to 0.44%(P he compliance with the clinical guidelines increased in cases requiring intervention. The rates for moderate/severe hypoxic neonatal encephalopathy were consistently low, 0.55 and 0.68 per 1000 deliveries, respectively, and corresponding to previous findings. The rate of operative delivery did not change during the 2 years in the total population. Conclusion: Increasing STAN usage provided consistent improvements in fetal outcome equalling those noted in the Swedish randomized controlled trial(RCT) without increasing operative interventions for fetal distress.

Triosephosphate isomerase （TPI） catalyzes the interconversion of glyceraldehyde-3-phosphate to dihydroxyacetone phosphate. Photosynthetic organisms generally contain two isoforms of TPI located in both cytoplasm and chloroplasts. While the cytoplasmic TPI is involved in the glycolysis, the chloroplastic isoform participates in the Calvin-Benson cycle, a key photosynthetic process responsible for carbon fixation. Compared with its cytoplasmic counterpart, the functional features of chloroplastic TPI have been poorly investigated and its three-dimensional structure has not been solved. Recently, several studies proposed TPI as a potential target of different redox modifications including dithiol/disulfide interchanges, glutathionylation, and nitrosylation. however, neither the effects on protein activity nor the molecular mechanisms underlying these redox modifications have been investigated. here, we have produced recombinantly and purified TPI from the unicellular green alga Chlamydomonas reinhardtii （Cr）. The biochemical properties of the enzyme were delineated and its crystallographic structure was determined at a resolution of 1.1 A. CrTPI is a homodimer with subunits containing the typical （β/α）8-barrel fold. Although no evidence for TRX regulation was obtained, CrTPI was found to undergo glutathionylation by oxidized glutathione and trans-nitrosylation by nitrosoglutathione, confirming its sensitivity to multiple redox modifications.

从二倍体细胞大染色体组(Macrochromosomes)的G带特征比较分析,鹤形目的黑水鸡与鸡形目的家鸡带型相似程度很大,标志着这两种鸟类的亲缘关系较近,同时也充分说明了不同目鸟类在进化上染色体变异的保守性。其带型差异仅在于两次臂间倒位、两次臂内倒位和一次着丝点融合。此外,我们采用QM荧光——银染的相继染色法发现黑水鸡的W染色体上有nor存在,这种核仁组织者区域与性染色质发生连锁的现象在鸟类是首次发现。

Mimis Souliotis： A Poet with Balkan historical Coordinates

Journal of Literature and Art Studies 2018年第2期8卷 200-209页

作者： Triantafyllos h. Kotopoulos Angeliki Pechlivani University of Western Macedonia Florina Greece

Mimis Souliotis, who was a poet, belongs to the lyrical generation of the 70＇s, a typically ＂urban＂, literary period in the sense that poetry is part of a neo-realist framework along the lines of its great ancestors, Cavafy and Karyotakis. M. Souliotis deviates from the ＂urban poetry＂ of his prominent fellow-craftsmen. Despite of his having been brought up and nurtured in big cities （Athens, Thessaloniki）, his poetry has northwestern coordinates and focuses on Florina, his long-term domicile. As part of the northwest region of the Balkanian Macedonia, Florina is the main spacial work stream of his poetry, a reference field that is not only geographical but also deeply historical and existential. The provincial heartland of the Balkanian Macedonia enlarges upon his work repeatedly＇either as a geophysical landscape and as a river network, or as a climatic reality, as a historical reference and cultural tradition at times and, more often than not, as a linguistic impact, provided that there are several Slavic place names in his poetry. The Balkanian province is neither M. Soulioti＇s nostalgic reminiscence nor a painful flashback and, simultaneously, a redeeming feature in the past. It is nothing but his vividly experienced era, across his whole space-time fluidity. The ubiquitous use of rural area in M. Soulioti＇s poetry is not either a sightseeing ＂aspect＂ or a self- governed geographic entity but pure history and Language. he is interwoven with historical experiences and linguistic idioms from The Dust of Time＇an ontology and existence, not bound to national geographical lines. It is a perpetual and indissoluble Balkan anthropology experienced as part of an everyday reality

Multivariate analysis and filtering techniques are widely applied to simultaneous and/or selective determination of multicomponent systems. Many methods among them are based on the principle of linear addition, while this principle does not always hold due to various physical and chemical factors. Using quite a different way, neural network (NN) based on a given learning rule, such as back propagation (BP) model, needs neither knowing nor using any form of input/output relationship. Particularly, NN can resolve various problems such as those with casual relation, those with fuzzy backgrounds, and those with uncertain inferential processes. NN was used by us to investigate quantitative struc-
