Differential Efficacy of Advanced Therapies in Inducing Remission in Ulcerative Colitis Based on Prior Exposure to TNF Antagonists.

Background And Aims: We sought to ascertain how prior exposure to TNF antagonists impacts treatment response with various classes of advanced therapies in patients with ulcerative colitis (UC), through a systematic review and meta-analysis.

Methods: Through a systematic review of multiple databases through June 30, 2024, we identified 17 RCTs in 8871 adults with moderate-severe UC who were treated with different advanced therapies vs. placebo, and reported efficacy in induction of clinical remission, stratified by prior exposure to TNF antagonists.

Pseudo-linkage or real-linkage of rust resistance genes in a wheat-Thinopyrum intermedium translocation line.

We analysed the chromosomal structures of two wheat-Thinopyrum intermedium addition lines Z4 and Z5 and resolved the linkage relationship between the leaf rust and stripe rust resistance genes in Z4. Wheat addition lines Z4 and Z5 carrying rust resistance genes from Thinopyrum intermedium (JJJJStSt, 2n = 6x = 42) together with three wheat lines involved in the production of these addition lines were analysed by rust response, 90K SNP genotyping, and molecular cytogenetic analysis. Seedling leaf rust (LR) responses to five diverse pathotypes indicated that the LR resistance gene(s) was located in translocation chromosome T3DS-3AS.

Green synthesis and characterization of CuO/PANI nanocomposite for efficient Pb (II) adsorption from contaminated water.

This study presents the synthesis of a green polymer-based nanocomposite by incorporating green CuO nanoparticles into polyaniline (PANI) for the adsorption of Pb (II) ions from contaminated water. The nanocomposite was extensively characterized using FTIR, XRD, BET, SEM-EDX, XPS, and Raman spectroscopy, both before and after Pb(II) adsorption. Optimization studies were performed to assess the effects of key parameters, including pH, adsorbent dosage, and initial ion concentration on the adsorption process.

Biodegradation of plasticizers by novel strains of bacteria isolated from plastic waste near Juhu Beach, Mumbai, India.

Phthalic acid esters are pivotal plasticizers in various applications, including cosmetics, packaging materials, and medical devices. They have garnered significant attention from the scientific community due to their persistence in ecosystems. The multifaceted aspects of PAEs, encompassing leaching, transformation, and toxicity, underscore their prominence as primary components of anthropogenic waste.

Role of centchroman in regression of fibroadenoma: A 2-arm randomized control trial.

Background: Fibroadenomas are common benign breast lumps that can cause anxiety due to malignancy concerns, and Centchroman, a selective estrogen receptor modulator, has shown promise in reducing their size. This study aimed to evaluate the efficacy of Centchroman in reducing fibroadenoma size, mastalgia, anxiety, and depression in affected patients.

Methodology: A parallel-arm randomized controlled trial was conducted at a tertiary care Breast Clinic with 104 patients aged 18‒45 years having fibroadenomas ≤ 3 cm.
