UDP-N-acetyl-D-glucosamine (UDP-GlcNAc) is an essential precursor of peptidoglycan and the rhamnose-GlcNAc linker region of mycobacterial cell wall. In Mycobacterium tuberculosis H37Rv genome, Rv1018c shows strong homology to the GlmU protein involved in the formation of UDP-GlcNAc from other bacteria. GlmU is a bifunctional enzyme that catalyzes two sequential steps in ...

The female reproductive tract is amongst the main routes for Human Immunodeficiency Virus (HIV) transmission. Cervical mucus however is known to protect the female reproductive tract from bacterial invasion and fluid loss and regulates and facilitates sperm transport to the upper reproductive tract. The purpose of this study was to ...

Clinical observation shows pregnant women under antiretroviral therapy present bleeding episodes at delivery, although this therapy promotes a decrease in fibrinolysis in nonpregnant patients, suggesting a prothrombotic state in the former. Since these drugs provoke hepatic disorders, they can cause bleeding disturbances. We investigated effects of antiretroviral therapy on hemostasis ...

Circadian clocks rhythmically coordinate biological processes in resonance with the environmental cycle. The clock function relies on negative feedback loops that generate 24-h rhythms in multiple outputs. In Arabidopsis thaliana, the clock component TIMING OF CAB EXPRESSION1 (TOC1) integrates the environmental information to coordinate circadian responses. Here, we use chromatin ...

The plasma metalloprotease ADAMTS13 (A Disintegrin And Metalloprotease with ThromboSpondin type 1 motif 13) cleaves prothrombotic ultralarge multimers of the platelet-adhesive protein von Willebrand factor (ULVWF) into less active multimers that promote haemostasis in injured blood vessels. When the enzyme is dysfunctional or undetectable, circulating ULVWF may cause massive intravascular ...

Sixteen linear ethoxylated alcohol surfactants (AEOs) were studied to determine their contact insecticidal activity to adult German cockroaches, Blattella germanica (L.) (Blattodea: Blattellidae). Within groups of AEOs of equal carbon chain length, insecticidal activity, measured as LT50 values (in minutes) and 24-h mortality after treatment, was inversely related to the ...

We investigated the serial changes in blood protein S (PS) and related proteins in 11 normal pregnant women. The PS activity decreased significantly in the third trimester and reached minimum levels (23.3%) one hour after delivery. Although the PS activity was reduced markedly below the normal limits, all the women ...

Parturition at term, the end stage of a successful pregnancy, occurs as a result of powerful, co-ordinated and periodic contractions of uterine smooth muscle (myometrium). To occur in a propitious manner, a high degree of control over the activation of a myometrial cell is required. We review the molecular mechanisms ...

Few studies document longitudinal changes in physical activity from prepregnancy to the postpartum period. This study estimated change in self-reported leisure-time physical activity in 1442 women before pregnancy, during the second trimester, and at 6 months postpartum. In addition, it also examined predictors of becoming insufficiently active during or after ...

BACKGROUND: Maternal serum concentrations of pregnancy-associated plasma protein-A (PAPP-A, pappalysin-1, EC 3.4.24.79) are used to predict the occurrence of Down syndrome. In pregnancy, PAPP-A primarily circulates as a covalent 2:2 complex with the proform of eosinophil major basic protein (proMBP), which inhibits the proteolytic activity of PAPP-A. At term, however, ...

Numerous studies have observed and analyzed the external electrical activity of the uterus, the so-called electrohysterogram (EHG), associated with contractions during pregnancy and labor. The EHG is mainly composed of two distinct frequency components, FWL (Fast Wave Low, low frequency component) and FWH (Fast Wave High, high frequency component). It ...

Burn injury is rare during pregnancy. However, severe burn injury during pregnancy is very dangerous for both mother and foetus. Maternal and foetal outcome depends on the mother's total body surface area (TBSA) burned. In women with more than 50% TBSA burned, foetal and maternal complications are considerable. Our study ...

The ongoing interest in very efficient systems for the imitation of cytochrome P-450-dependent monooxygenase reactions, consisting of metalloporphyrin and oxygen donor, prompted us to develop a method to compare the catalytic activity of soluble metalloporphyrins with those which have been immobilised on different silica surfaces. In this article, we describe ...

We evaluated the impact of peroxisome proliferator-activated receptor (PPAR)alpha activation and dexamethasone treatment on islet adaptations to the distinct metabolic challenges of fasting and pregnancy, situations where lipid handling is modified to conserve glucose. PPARalpha activation (24 h) in vivo did not affect glucose-stimulated insulin secretion (GSIS) in nonpregnant female ...

BACKGROUND: Pregnancy is associated with changes in the immune system. Although previous studies have focussed mainly on adaptive immunity, there are indications that components of innate immunity, such as mannose-binding lectin (MBL), are associated with pregnancy outcome. Although this would suggest that pregnancy also involves adaptations in innate immunity, there ...

Fluid and HCO(3)(-) secretion are vital functions of the pancreatic duct and other secretory epithelia. CFTR and Cl(-)/HCO(3)(-) exchange activity at the luminal membrane are required for these functions. The molecular identity of the Cl(-)/HCO(3)(-) exchangers and their relationship with CFTR in determining fluid and HCO(3)(-) secretion are not known. ...

Previous studies indicate that noise induced hearing loss (NIHL) involves a decrease in glutathione peroxidase (GPx) activity and a subsequent loss of outer hair cells (OHC). However, the cellular localization of this GPx decrease and the link to OHC loss are still poorly understood. In this report, we examined the ...

BACKGROUND: Participation in physical activity during pregnancy may reduce the risk of gestational diabetes mellitus and preeclampsia and help prevent excess maternal weight gain. However, studies describing patterns and correlates of activity during pregnancy are sparse. The purpose of this cross-sectional study was to describe total physical activity (household/caregiving, occupational, ...

Leprosy responds very slowly to the current multidrug therapy, and hence there is a need for novel drugs with potent bactericidal activity. PA-824 is a 4-nitroimidazo-oxazine that is currently undergoing phase I clinical trials for the treatment of tuberculosis. The activity of PA-824 against Mycobacterium leprae was tested and compared ...

It has been shown previously in a number of systems that after an extended block of activity, synaptic strength is increased. We found that an extended block of synaptic activity at the mouse neuromuscular junction, using a tetrodotoxin cuff in vivo, increased synaptic strength by prolonging the evoked endplate current ...
