Evaluating the impact of the combined acute toxicity of iron (Fe) and microplastics on Namalycastis jaya.

The rising concern over heavy metals (HMs) and microplastics (MPs) pollution in marine ecosystems, primarily driven by anthropogenic activities, poses significant threats to ecological health. Understanding the combined exposure of HMs and MPs aids in toxicity assessment. In this study, we examined the combined effects of polystyrene microplastics (MPs) and iron (Fe) on oxidative stress, bioaccumulation, histopathology, and genotoxicity in Namalycastis jaya.

Perceptual Constancy in the Speed Dependence of Friction During Active Tactile Exploration.

Fingertip friction is a key component of tactile perception. In active tactile exploration, friction forces depend on the applied normal force and on the sliding speed chosen. We have investigated whether humans perceive the speed dependence of friction for textured surfaces of materials, which show either increase or decrease of the friction coefficient with speed.

Progression of diabetic retinopathy following uncomplicated phacoemulsification: A prospective study from South India.

Aim: The aim of this study was to study the progression of diabetic retinopathy (DR) and macular edema in uncomplicated phacoemulsification in patients with diabetes mellitus with a follow-up of 6 months.

Methods: A prospective, nonrandomized study was conducted on patients with established or no DR in a known case of diabetes mellitus undergoing cataract surgery by phacoemulsification, with no intraoperative complications. Detailed ophthalmic evaluation including fundus examination was done in all cases, and DR staging was done.

Trophic transfer and their impact of microplastics on estuarine food chain model.

Microplastic contamination in marine ecosystems, and its negative effects through trophic transfer among marine organisms, remains a growing concern. Our study investigates the trophic transfer and individual impacts of polystyrene microplastics (MPs) in an estuarine food chain model, comprising Artemia salina as primary organism, Litopenaeus vanamei as secondary organism, and Oreochromis niloticus as tertiary organism. A.

Netarsudil monotherapy as the initial treatment for open-angle glaucoma and ocular hypertension in Indian patients: A real-world evaluation of efficacy and safety.

Purpose: Glaucoma is the second leading cause of blindness worldwide, affecting more than 64 million people aged 40-80. The best way to manage primary open-angle glaucoma (POAG) is by lowering the intraocular pressure (IOP). Netarsudil is a Rho kinase inhibitor, the only class of antiglaucoma medications that reorganizes the extracellular matrix to improve the aqueous outflow through the trabecular pathway.
