Benzothiazole-2-sulfonate (BTSO3) is one of the side products occurring in 2-mercaptobenzothiazole (MBT) production wastewater. We are the first to isolate an axenic culture capable of BTSO3 degradation. The isolate was identified as a Rhodococcus erythropolis strain and also degraded 2-hydroxybenzothiazole (OBT) and benzothiazole (BT), but not MBT, which was found to inhibit the biodegradation of OBT, BT, and BTSO3. In anaerobic resting cell assays, BTSO3 was transformed into OBT in stoichiometric amounts. Under aerobic conditions, OBT was observed as an intermediate in BT breakdown and an unknown compound transiently accumulated in several assays. This product was identified as a dihydroxybenzothiazole. Benzothiazole degradation pathways seem to converge into OBT, which is then transformed further into the dihydroxy derivative.

Water contamination by polycyclic aromatic hydrocarbons (PAHs), particularly naphthalene, is a serious environmental concern due to its persistence, bioaccumulation, and toxicity. This study explores the adsorption behavior of naphthalene using organobentonite (OBt), synthesized by intercalating cetyltrimethylammonium bromide (CTAB) into sodium bentonite (SBt) with varying cation exchange capacities (CECs). The effectiveness of OBt in naphthalene adsorption was evaluated by analyzing key parameters, including CEC, contaminant concentration, and contact time.

Aim: To explore the potential roles of mitochondrial dysfunction in the initiation of inflammation in periodontal macrophages and to determine the mechanism underlying the involvement of dynamin-related protein 1 (Drp1) in macrophage inflammatory responses through its interaction with hexokinase 1 (HK1).
Materials And Methods: Gingival tissues were collected from patients diagnosed with periodontitis or from healthy volunteers. Drp1 tetramer formation and phosphorylation were analysed using western blot.

Objective: The aim of this study was to assess the precision and safety of targeted microwave ablation (TMA) using organ-based tracking (OBT) fusion, in patients with intermediate risk prostate cancer.
Patients And Method: We conducted a prospective, multicentric trial. Eligible patients had a prostate-specific antigen (PSA) < 20 ng/mL, a magnetic resonance imaging (MRI)-visible index tumour of Gleason score 3 + 4, with largest axis ≤15 mm and distant of at least 5 mm from the rectum and apex.
Gastrointestinal pathology in patients presenting with iron deficiency anaemia: A single-centre cross-sectional study.

Background: About a third of the world's population is estimated to suffer from anaemia, and iron deficiency is expected to account for about half of all anaemia cases. This study was designed to get an estimate of the proportion of patients with iron deficiency anaemia (IDA) who have a significant gastrointestinal (GI) pathology, in particular a GI malignancy, and to identify any risk factors or predictors for the same.
Methods: This cross-sectional study was conducted at a hospital in Eastern India.

Article Synopsis
- * Findings indicate that elevated temperatures combined with tritium exposure lead to cell damage, reduced photosynthetic efficiency, and disruptions in key metabolic pathways, exacerbating genetic damage in the algae.
- * The research highlights the importance of re-evaluating potential ecological risks linked to low-level tritium waste discharge in the context of global warming and rising sea temperatures.
