HIV-related Differences in Placental Immunology: Data From the PRACHITi Cohort in Pune, India.

Background: Maternal HIV infection can affect placental immunology and expression of the neonatal crystallizable fragment receptor (FcRn), which allows transplacental antibody transfer. This study delineated differences in placental FcRn and T-cell expression by HIV status, with or without viral suppression.

Methods: This observational cohort study in Pune, India, followed pregnant women with and without HIV through 1 year postpartum; 42 had placenta collected, stratified by HIV status.

A randomised controlled non-inferiority trial to compare the efficacy of 'HPV screen, triage and treat' with 'HPV screen and treat' approach for cervical cancer prevention among women living with HIV.

We report results of a randomized controlled trial to compare 'HPV screen and treat' (Arm 1) and 'HPV screen, triage and treat' (Arm 2) in women living with HIV (WLHIV), using visual inspection with acetic acid (VIA) as the triaging test. Treatment was offered to all HPV-positive women in Arm 1 and to VIA-positive women in Arm 2 with either thermal ablation or large loop excision. All women underwent a repeat HPV test one year after randomization.

ABA-auxin cascade regulates crop root angle in response to drought.

Enhancing drought resistance through the manipulation of root system architecture (RSA) in crops represents a crucial strategy for addressing food insecurity challenges. Abscisic acid (ABA) plays important roles in drought tolerance; yet, its molecular mechanisms in regulating RSA, especially in cereal crops, remain unclear. In this study, we report a new mechanism whereby ABA mediates local auxin biosynthesis to regulate root gravitropic response, thereby controlling the alteration of RSA in response to drought in cereal crops.

Discordance of 3rd and 4th generation QuantiFERON-TB Gold assays by pregnancy stages in India.

Methods: We screened 516 pregnant women for TB infection (TBI) with IGRA.

Current Advances in Lipid-Based Drug Delivery Systems as Nanocarriers for the Management of Female Genital Tuberculosis.

Female genital tuberculosis (FGTB) arises from infection and can rarely be caused by or atypical mycobacteria. FGTB usually arises from tuberculosis (TB) that affects the lungs or other organs. The infection can enter the vaginal tract directly from abdominal TB or by hematogenous or lymphatic pathways.

Auxin-dependent post-translational regulation of MONOPTEROS in the Arabidopsis root.

Auxin plays a pivotal role in plant development by activating AUXIN RESPONSE FACTORs (ARFs). Under low auxin levels, ARF activity is inhibited by interacting with Aux/IAAs. Aux/IAAs are degraded when the cellular auxin concentration increases, causing the release of ARF inhibition.

The first intron of ARF7 is required for expression in root tips.

Auxin regulates plant growth and development through the transcription factors of the AUXIN RESPONSE FACTOR (ARF) gene family. ARF7 is one of five activators that bind DNA and elicit downstream transcriptional responses. In roots, ARF7 regulates growth, gravitropism and redundantly with ARF19, lateral root organogenesis.

Integrating cryo-OrbiSIMS with computational modelling and metadynamics simulations enhances RNA structure prediction at atomic resolution.

The 3D architecture of RNAs governs their molecular interactions, chemical reactions, and biological functions. However, a large number of RNAs and their protein complexes remain poorly understood due to the limitations of conventional structural biology techniques in deciphering their complex structures and dynamic interactions. To address this limitation, we have benchmarked an integrated approach that combines cryogenic OrbiSIMS, a state-of-the-art solid-state mass spectrometry technique, with computational methods for modelling RNA structures at atomic resolution with enhanced precision.

Synthesis, Molecular Docking Studies and Biological Evaluation of Thiazolyl Hydrazone Derivatives of Chromone-3-carbaldehyde as Potent Anti-Oxidant and Anti-Inflammatory Agents.

Introduction: A series of 15 thiazolyl hydrazone derivatives of chromone-3- carbaldehyde have been designed and synthesized by the cyclization of thiosemicarbazone derivatives of chromone-3-carbaldehydes with 4'-substituted-2-bromo acetophenones.

Ethylene regulates auxin-mediated root gravitropic machinery and controls root angle in cereal crops.

Root angle is a critical factor in optimizing the acquisition of essential resources from different soil depths. The regulation of root angle relies on the auxin-mediated root gravitropism machinery. While the influence of ethylene on auxin levels is known, its specific role in governing root gravitropism and angle remains uncertain, particularly when Arabidopsis (Arabidopsis thaliana) core ethylene signaling mutants show no gravitropic defects.

Reviving grain quality in wheat through non-destructive phenotyping techniques like hyperspectral imaging.

A long-term goal of breeders and researchers is to develop crop varieties that can resist environmental stressors and produce high yields. However, prioritising yield often compromises improvement of other key traits, including grain quality, which is tedious and time-consuming to measure because of the frequent involvement of destructive phenotyping methods. Recently, non-destructive methods such as hyperspectral imaging (HSI) have gained attention in the food industry for studying wheat grain quality.
