Insights Into the Conformational Dynamics of the Cytoplasmic Domain of Metal-Sensing Sensor Histidine Kinase ZraS.

ZraS is a metal sensor integral to ZraPSR, a two-component signaling system found in enterobacters. It belongs to a family of bifunctional sensor histidine kinases (SHKs) and is speculated to sense zinc-induced stress on the bacterial envelope. Information on the structure-function relationship of sensor kinases is elusive due to the lack of full-length structures, intrinsically dynamic behavior, and difficulty trapping them in active state conformations.

Anesthetic Management of Cesarean Sections in Parturients with Valvular Heart Disease.

Valvular heart disease during pregnancy and labor poses a significant threat to maternal and fetal outcomes, increasing morbidity. The physiological changes of pregnancy in a parturient with stenotic and regurgitant lesions increases the risk of cardiac decompensation. Moderate-to-severe stenotic lesions can deteriorate in pregnancy due to an increase in workload on the heart, leading to complications such as congestive heart failure, atrial fibrillation, and thromboembolism.

A Contemporary Insight Into the Seroepidemiology of Herpes Simplex Virus Infection in the Sub-Himalayan Region: Seroepidemiology of HSV Infection in North India.

Infection by human herpes simplex virus type 1 and type 2 (HSV-1/2) is common globally though with wide regional variability. Seroepidemiology of HSV-1/2 infections is of utmost importance in formulating control strategies, but there is a paucity of data from many regions of India. This study aimed to determine the prevalence of anti-HSV-1/2 antibodies in Uttarakhand and adjoining areas and to study its pattern and distribution in different subgroups.

Does induction or augmentation of labor increase the risk of postpartum hemorrhage in pregnant women with anemia? A multicenter prospective cohort study in India.

Objective: To investigate whether induction/augmentation of labor in pregnant women with anemia increases the risk of postpartum hemorrhage (PPH) and whether this risk varied by indications for labor induction/augmentation and by anemia severity in pregnancy.

Methods: In a prospective cohort study of 9420 pregnant women from 13 hospitals across India, we measured hemoglobin concentrations at recruitment (≥28 weeks of gestation) and blood loss after childbirth during follow-up and collected clinical information about PPH. Clinical obstetric and childbirth information at both visits were extracted from medical records.

Haematological Profile in Patients With Acute Falciparum Malaria: A Hospital-Based Study.

Introduction Malaria is the most common parasitic disease affecting humans. Haematological alterations in malaria are expected, and these changes play a significant role in fatal complications. The present study aims to assess the clinical and haematological profile in patients with acute falciparum malaria and the significance of various haematological and coagulation alterations with the clinical severity of malaria.
