Assessment of Barriers and Enablers for Implementing a Population-Based Childhood Cancer Registry in Chennai, India.

Background: Despite most childhood cancer cases being diagnosed in low- and middle-income countries, there is a significant deficit of population-based childhood cancer registries (PBCCRs) in these regions. To address this critical gap, we established India's first dedicated PBCCR in Chennai on October 4, 2022, covering children aged 0-19. This study aims to identify the barriers and enablers to implementing the Chennai PBCCR.

Toxicity optimization of green zinc oxide quantum dots in zebrafish using Box-Behnken design: a novel approach for safer nanoparticle synthesis.

Zinc oxide quantum dots, also known as ZnO QDs, are highly desirable due to their numerous favorable characteristics, such as their beneficial photoluminescence, solubility in water, along with sunlight absorption. They are well-suited for use in biomedical applications, drugs, and bioimaging. However, study on the toxicology of these QDs is needed before they can be used in humans.

Errors in diabetic insulin therapy and the vitality of proper precautions in Bangladesh: Real-life insights from the developing world.

Background: Insulin therapy errors can have life-threatening consequences in patients with diabetes. Given the increasing prevalence of diabetes and insulin therapy in Bangladesh, it is crucial to identify and prevent these errors. This study uses case-based clinical experiences to thematically analyze insulin therapy errors and propose preventive measures.

Pmu1a, a novel spider toxin with dual inhibitory activity at pain targets hNa 1.7 and hCa 3 voltage-gated channels.

Venom-derived peptides targeting ion channels involved in pain are regarded as a promising alternative to current, and often ineffective, chronic pain treatments. Many peptide toxins are known to specifically and potently block established therapeutic targets, among which the voltage-gated sodium and calcium channels are major contributors. Here, we report on the discovery and characterization of a novel spider toxin isolated from the crude venom of Pterinochilus murinus that shows inhibitory activity at both hNa 1.

The Cytotoxic Effectiveness of Thiourea-Reduced Graphene Oxide on Human Lung Cancer Cells and Fungi.

This study demonstrated the effective reduction of graphene oxide (GO) by employing thiourea as a reducing and stabilizing agent. Two fungi ( and ) were used for anti-fungal assay. Cell viability, cell cycle analysis, DNA fragmentation, and cell morphology were assessed to determine the toxicity of thiourea-reduced graphene oxide (T-rGO) on human lung cancer cells.
