Abortion-seeking behaviour among Nigerian women

This study used data from a community-based survey to examine women's experiences of abortion in Nigeria. Fourteen percent of respondents reported that they had ever tried to terminate a pregnancy, and 10% had obtained an abortion. The majority of women who sought an abortion did so early in the pregnancy. Forty-two percent of women who obtained an abortion used the services of a non-professional provider, a quarter experienced complications and 9% sought treatment for complications from their abortions. Roughly half of the women who obtained an abortion used a method other than D&C or MVA. The abortion prevalence and conditions under which women sought abortions varied by women's socio-demographic characteristics. Because abortion is illegal in Nigeria except to save the woman's life, many women take significant risks to terminate unwanted pregnancies. Reducing the incidence of unwanted pregnancy and unsafe abortion can significantly impact the reproductive health of women in Nigeria.     

印度地鼠的性成熟和窝仔数

为有效地进行有害脊椎动物的控制 ,研究了栖息于巴基斯坦Punjab中部的 348只印度地鼠的繁殖模式。在所捕捉到的 10 7雄鼠和 2 4 1只雌鼠中 ,分别有 75只和 179只是性成熟的个体。性比偏雌。使用被捕个体标本的体重和体长作为指标 ,发现最小的性成熟的雄性个体体重为 70 - 89g ,体长 13 1- 14 0cm ;一窝仔里面的平均胚胎数为 2 74± 0 15 (范围 ,1- 5 ) ,而平均胎斑数为 4 2 9± 0 19(1- 11) .体重似乎对窝仔数有显著影响 ,而体长和估计的年龄对窝仔数没影响。当老鼠繁殖不活跃和不繁殖时 ,控制害兽最有效     

Plasmodium chabaudi: Expression of active recombinant chabaupain-1 and localization studies in Anopheles sp.

Plasmodium cysteine proteases have been shown to be immunogenic and are being used as malaria potential serodiagnostic markers and vaccine targets. Genes encoding two Plasmodium chabaudi cysteine proteases chabaupain-1 (CP-1) and chabaupain-2 (CP-2) were identified and further expressed in Escherichia coli. Solubilisation of recombinant CP-1 and CP-2 was achieved by decreasing the temperature of induction.Anopheles gambiae tissues infected with Plasmodium were analyzed by Western blotting using the anti-CP-1 antibody showing that CP-1 is only present in the A. gambiae midguts being absent from other infected mosquito biological material. Anti-CP-1 anti-serum recognized a 30 kDa band in P. chabaudi, Plasmodium berghei and Plasmodium yoelii lysates but does not recognize the recombinant CP-2 extracts suggesting high antibody specificity.     

Modification of Anti-Glycan IgG and IgM Profiles in Allergic Inflammation

Glycans and anti-glycan antibodies (AGAs) are essential for infiltration of inflammatory cells in various allergies. The glycocalyx structure of the cells is modified during disease progression, and this modification is possible to evaluate by assessment of AGAs. A printed glycan array with 55 immobilized glycans and immobilized antibodies to IgG, IgA, and IgM was used to study the changes in AGA profiles in bronchial asthma (BA). Levels of antibodies to certain glycans in BA patients statistically differed from levels in healthy donors (p < 0.0007 by the Mann–Whitney test); the glycan set included 6Su-6`-SiaLec, Sia LeX, Sia6Htype2; Tαα, Manβ1-4GlcNAc, and Manα1-4Manβ. The obtained results help to better understand the mechanisms of the cell-mediated immune response in bronchial asthma and other types of allergic reactions.     

Exosomal surface protein markers in diagnosis of colorectal cancer

Colorectal cancer (CRC) is one of the most common primary malignancies. Early stages of the disease are asymptomatic in the majority of cases, leading to late detection and high mortality. Available noninvasive diagnostic techniques are limited in sensitivity and specificity, and designing new ones is still a pressing problem. Exosomes are membrane-derived microvesicles secreted into human biological fluids and provide a novel way to assess the course of an oncology disease. The review describes the repertoire of exosomal surface biomarkers found in the blood of CRC patients and the prospects of employing multiplexed tests for exosomal markers in early noninvasive diagnosis of cancer.     

T-cadherin activates Rac1 and Cdc42 and changes endothelial permeability

In the present study, expression of T-cadherin was shown to induce intracellular signaling in NIH3T3 fibroblasts: it activated Rac1 and Cdc42 (p < 0.01) but not RhoA. T-Cadherin overexpression in human umbilical vein endothelial cells (HUVEC) using adenoviral constructs induced disassembly of microtubules and polymerization of actin stress fibers, whereas down-regulation of endogenous T-cadherin expression in HUVEC using lentiviral constructs resulted in micro-tubule polymerization and a decrease in the number of actin stress fibers. Moreover, suppression of the T-cadherin expression significantly decreased the endothelial monolayer permeability as compared to the control (p < 0.001).     

Left-ventricular heart aneurism as a new source of resident cardiac stem cells

In the past few years, it has been established that the heart contains a reservoir of stem and progenitor cells. These cells are able to differentiate in cardiomyogenic, endothelial, and smooth muscle lineages in vitro and in vivo and, following injection into an infarcted myocardium, these cells prevent the remodeling of the left ventricle and improve cardiac function. The aim of the present study was the immunophenotypic characterization of resident stem cells in the tissue of a chronic left aneurism, an analysis of their localization, and distribution in various aneurism areas.
