Dendrimer-modified carbon nanotubes for the removal and recovery of heavy metal ions from water.

Effective removal of trace heavy metal ions from aqueous bodies is a pressing problem and requires significant improvement in the area of absorbent material in terms of removal efficiency and sustainability. We propose an efficient strategy to enhance the adsorption efficiency of carbon nanotubes (CNTs) by growing dendrimers on their surface. First, CNTs were pre-functionalized with maleic acid (MA) via Diels-Alder reaction in presence of a deep eutectic solvent under ultrasonication.

Contamination profile and potential human health risks of radon in groundwater of southwest region of Punjab, India.

Radon (Rn) is a naturally occurring radioactive gas produced by the decay of uranium-bearing minerals in rocks and soils. Long-term exposure to elevated radon levels in drinking water is associated with an increased risk of stomach and lung cancers. This study aims to assess the concentration of radon in groundwater and evaluate its potential health risks in six cancer-affected districts, i.

Efficacy and safety of protamine sulfate following carotid artery stenting.

Background: protamine sulfate is used to reduce bleeding risk after Carotid Artery Stenting (CAS), but its efficacy in personalized patient settings remains underexplored. This study aims to identify factors associated with greater benefits from protamine sulfate following CAS.

Methods: A retrospective review of Vascular Quality Initiative (VQI) data (2016-2022) identified patients undergoing CAS, divided into Transfemoral CAS (TF-CAS) and Transcarotid artery revascularization (TCAR) groups.

Targeting protein misfolding in Alzheimer's disease: The emerging role of molecular chaperones.

Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterised by cognitive decline and the accumulation of misfolded proteins, including amyloid-beta and hyperphosphorylated tau, which impair neuronal function and promote cell death. These misfolded proteins disrupt proteostasis by forming toxic aggregates that exacerbate disease progression. Molecular chaperones, such as heat shock proteins, actively maintain protein homeostasis by assisting in proper folding, preventing aggregation, and promoting the clearance of misfolded proteins.
