Occurrence of histone H1° protein in rat alveolar macrophages

Histone H1 of rat alveolar macrophages, neutrophilic granulocytes and monocytes extracted with 5% (v/v) perchloric acid was studied in order to see whether a protein similar to histone H1° of rat liver exists in these specialized cells. The biochemical methods used involved SDS and acid-urea polyacrylamide gel electrophoresis, gel filtration on BioGel P100 and raising antisera against chromatographically purified rat liver H1° and histone H1. The antiserum was applied for further characterization of the presumptive H1° fraction using ELISA and Western blot analysis.The results from our studies showed that histone H1° protein is present in rat alveolar macrophages, monocytes and neutrophilic granulocytes, but its quantity in neutrophilic granulocytes is very much less than macrophages and monocytes.     

Current Perspectives on Plant Growth-Promoting Rhizobacteria

The rhizosphere of plant species is an inimitable ecosystem that harbors an extensive range of microbes. Research in the wide areas of rhizosphere biotechnology highlighting new bioinoculants has received ample attention during recent past, and suitable expertises have been developed. However, the global recognition of such technologies by farmers is still overwhelmed with doubts owing to limited shelf-life and efficiency of the products which demonstrate discrepancies. This review illustrates plant growth-promoting rhizobacteria with detailed emphasis on nutrient acquisition and potential roles in conferring tolerance against abiotic stresses. The review demonstrates the recent research in the field of genomic and proteomic analysis, where systematic characterization of potentially effective rhizobacteria is being carried out by screening the extensive bacterial gene pool based on modern molecular tools. The review concludes by emphasizing the efforts made in the proteomics field which could compensate for understanding of prompt evolution in microbe-derived and plant-derived protein and metabolite substitute that activates vulnerability or resistance.

     

First report on the life history of the marine amphipod Ceradocus mizani and its implication for aquaculture

The search for alternative live feed for aquaculture stocks has inspired research into marine amphipods. In this study, the life history of Ceradocus mizani was evaluated to better understand how this amphipod might be used in aquaculture as an alternative feed. The amphipods did not display copulatory behavior during the study period. The females were multivoltine and attained sexual maturity on average in 23.6 days at a mean length of 4.64 mm. The incubation period lasted 8.8 days, and the mean number of juveniles produced per brood during that incubation period was relatively low (7.58). Females produced a mean of 5.2 consecutive broods and 39.4 total juveniles over the life span. (i.e., 0.33 juveniles/day). Sex ratio was female skewed (1.55:1). Female size and the number of juveniles produced per brood were positively correlated (R² = 0.63). The mean life span for females and males was 119.4 and 91.2 days, respectively. Mean maximum length was 9.26 mm for males and 8.18 mm for females. This is the first account of the life history of C. mizani and forms the basis for future studies of this marine amphipod.     

山黧豆属作物在土耳其的栽培与利用状况北大核心CSCD

众所周知,山黧豆起源于巴尔干半岛并传播到世界各地。在土耳其,山黧豆属作物有73个分类群(约1/3为地方特有种),在全国各地均有分布种植,但主要集中在黑海中部、东南部和安纳托利亚东部地区。该文介绍了山黧豆属作物在土耳其全国的分布和在局部地区的食用、观赏等资源利用和保存情况。通常,不同国家人民会因为文化差异形成不同的饮食习惯,但山黧豆大多被用于制作汤、面包或其他咸点。山黧豆的栽培技术则因地制宜,土耳其在边缘土地上进行旱作种植,中国和印度部分地区多采用轮作种植方法等。作为一种极“小众”的作物,山黧豆研究工作的从业人员极少,而且缺乏大型联合研究项目。因此,需要联合化学、表型和分子分析等方法,以保护世界各地包括土耳其在内的地方种质资源,尤其是培育适合土耳其、中国等世界各国的食饲兼用型低β-ODAP品种。总之,选育低β-ODAP或不含β-ODAP的山黧豆品种将有助于丰富人类在食用、饲用和观赏等方面的物种资源利用。

Control of a highly pathogenic H5N1 avian influenza outbreak in the GB poultry flock

The identification of H5N1 in domestic poultry in Europe has increased the risk of infection reaching most industrialized poultry populations. Here, using detailed data on the poultry population in Great Britain (GB), we show that currently planned interventions based on movement restrictions can be expected to control the majority of outbreaks. The probability that controls fail to keep an outbreak small only rises to significant levels if most transmission occurs via mechanisms which are both untraceable and largely independent of the local density of premises. We show that a predictor of the need to intensify control efforts in GB is whether an outbreak exceeds 20 infected premises. In such a scenario neither localized reactive vaccination nor localized culling are likely to have a substantial impact. The most effective of these contingent interventions are large radius (10 km) localized culling and national vaccination. However, the modest impact of these approaches must be balanced against their substantial inconvenience and cost.
