The incidence of tuberculosis (TB) in China is high, according to the Nationwide Random Survey for the Epidemiology of Tuberculosis, 1990, conducted by the Beijing Tuberculosis and Thoracic Tumor Research Institute (Tongzhou, Beijing, China). It is important to obtain fundamental data about drugresistant TB in China to enable successful treatment of this disease. In 1994, WHO launched the globa...

Mammalian placentation is dependent upon the action of trophoblast cells at the time of implantation. Appropriate fetal growth, regulated by maternal nutrition and nutrient transport across the placenta, is a critical factor for adult offspring long-term health. We have demonstrated that a mouse maternal low-protein diet (LPD) fed exclusively during preimplantation development (Emb-LPD) increas...

OBJECTIVES To evaluate the incidence of, and risk factors for, complications of endomyocardial biopsy in children. BACKGROUND Endomyocardial biopsy (EMB) is a low risk procedure in adults, but there is a paucity of data with regard to performing this procedure in children. METHODS Retrospective review of the morbidity and mortality of 1,000 consecutive EMB procedures. RESULTS One thousand...

Type IV collagen is a major component of basement membranes. We have characterized 11 mutations in emb-9, the alpha1(IV) collagen gene of Caenorhabditis elegans, that result in a spectrum of phenotypes. Five are substitutions of glycines in the Gly-X-Y domain and cause semidominant, temperature-sensitive lethality at the twofold stage of embryogenesis. One is a glycine substitution that causes ...

s of papers 9 The objective of this experiment was to determine differences between 10 breed crosses with regards to eggshell properties and embryo metabolism. Eggs from the flocks (51 to 54 weeks of age) were incubated in a single machine, moisture loss measurements were recorded. Additionally, embryo weight with out yolk (EMB) and residual yolk weight (YLK) were determined at 15, 18 and 21 d....

In this article we examine the effects of public self-consciousness (PSC) and a cross-situational reactivity to embarrassing encounters (EMB) on college students' levels of alcohol consumption by levels of perceived peer drinking. The analysis of self-report data from two undergraduate samples (n = 118 and n = 195) yielded virtually identical results and suggests that PSC and EMB affect alcohol...

This paper proposes a sensor-less robust force control method for improving the control performance of an electro-mechanical brake (EMB) which is applicable to commercial city buses. The EMB generates the accurate clamping force commanded by a driver through an independent motor control at each wheel instead of using existing mechanical components. In general, an EMB undergoes parameter variati...

The purpose of this project was to identify large numbers of Arabidopsis genes with essential functions during seed development. More than 120,000 T-DNA insertion lines were generated following Agrobacterium-mediated transformation. Transgenic plants were screened for defective seeds and putative mutants were subjected to detailed analysis in subsequent generations. Plasmid rescue and TAIL-PCR ...

SETTING Initial isolates should be tested for drug susceptibility to confirm the anticipated effectiveness of chemotherapy. OBJECTIVE To evaluate E-test strips for susceptibility testing of Mycobacterium tuberculosis. DESIGN A proportion method using Lowenstein-Jensen medium and the Bactec radiometric system were compared with the E-test (isoniazid [INH], rifampicin [RMP], ethambutol [EMB] ...

Introduction. Mesenchymal stromal cells (MSC) have immunomodulatory features. The aim of this study was to investigate the migration and homing potential of endogenous circulating MSC in virus negative inflammatory cardiomyopathy (CMi). Methods. In 29 patients with (n = 23) or without (n = 6) CMi undergoing endomyocardial biopsies (EMB), transcardiac gradients (TCGs) of circulating MSC were mea...
