Geogenic controls and anthropogenic inputs on the seasonal hydrogeochemical variability of the Paraopeba River basin, Brazil

Abstract This study investigates the combined effects of geology, land use and land cover, hydrological seasonality, and disturbance history on the hydrogeochemistry of surface waters in the Paraopeba River Basin (PRB), located in Minas Gerais State, southeastern Brazil, and form...

Beyond rare gases: Cooling of trapped BN− ions by H2 molecules

Quantum dynamics of collisional cooling of the BN- anion in a cold trap is carried out by using the ortho- and para-H2 molecules as a buffer gas. The calculations are performed using the full four-dimensional interaction potential energy surface in which both BN- and H2 are treat...

Psychiatric morbidity and coping in caregivers of patients with substance use disorder

Background Caregivers of patients with substance use disorders often experience psychological distress, but psychiatric morbidity and coping, including religious coping, remain under-studied in Indian treatment settingsObjective To assess psychiatric morbidity, coping strategies,...

Differential metabolic reprogramming of two potato (Solanum tuberosum L.) cultivars under Alternaria alternata infection and tenuazonic acid exposure using GC–MS and FTIR analyses

Potato ( Solanum tuberosum L.) is highly susceptible to Alternaria alternata and its phytotoxin tenuazonic acid (TeA), which disrupt host metabolism and induce oxidative stress. However, differences between toxin- and pathogen-driven metabolic reprogramming and their cultivar-spe...

Integrative approaches to enhancing abiotic stress tolerance in wheat crop through physiological and molecular strategies

Wheat is one of the world’s most important cereal crops, providing essential calories and nutrients for billions of people and playing a vital role in global food security. Its productivity is increasingly threatened by abiotic stresses, including salinity, drought, heavy metal t...

Cognitive preferences and hemispheric preference: an analysis of learning and thinking styles among undergraduate students

This study examines the influence of brain hemisphere preference on the learning and thinking styles of undergraduate students in the Malappuram district, Kerala, India. The primary aims were to identify students’ hemispheric preference using SOLAT test, assess their learning and...

An Algebraic Approach of Multilayer Color Image Cryptosystems via Permutation-Substitution Groups and Chaotic Maps

In this manuscript, an algebra-based image encryption scheme is presented, in which the application of an S-box derived from quadratic polynomial mappings over the ring ℤ256, chaotic maps, and an algebraically enriched random matrix affine cipher is included. The algebraic founda...

Recent Advances in 1,3‐Thiazinan‐4‐One Hybrids Bearing Diverse Heterocyclic Scaffolds: Synthesis Strategies and Therapeutic Potential

ABSTRACT The 1,3‐thiazinan‐4‐one scaffold is a privileged six‐membered sulphur‐ and nitrogen‐containing heterocyclic framework with distinctive electronic properties, conformational adaptability, and hydrogen‐bonding capabilities, making it an attractive pharmacophore in medicina...

Integrated source apportionment and geochemical background assessment of organic and inorganic components in Amazonian upland lakes: insights from an extensive basin-wide geochemical database

Abstract Purpose This study established reliable natural geochemical backgrounds for Amazonian upland lakes and evaluated how lateritic catchment materials are transferred and transformed in lake sediments across Carajás, Araguaia, and Xingu. Methods Ferruginous duricrusts and la...

Neuroprotective effect of normal and modified mesenchymal stem cell‐derived exosomes by mitigating Alzheimer's‐related oxidative and inflammatory damage via Nrf2/HO‐1 in SH‐SY5Y cells

Abstract Exosome therapy is emerging as a promising neuroprotective strategy for Alzheimer's disease (AD). We evaluated and compared whether normal exosomes (NE) and modified exosomes (ME) derived from AD rat brain extract‐treated rat bone marrow mesenchymal stem cells possess th...

Foreign body–associated maxillary sinus aspergillosis caused by Endomethasone extrusion: diagnostic challenges, biological mechanisms, and surgical management

Extrusion of endodontic sealers into the maxillary sinus is an uncommon but clinically significant complication, particularly when biologically active zinc oxide–eugenol–based materials are involved. Their persistence within the sinus may impair mucociliary clearance and sustain...
