Algae a Potential Source in Cosmetics: Current Status, Challenges, and Economic Implications.

Recently, many studies have revealed the association between environmental stresses and skin disorders. Skin protects the inner body organs as a first line of defence against various environmental detriments. The physical, chemical, biological, and environmental stresses and internal factors, including reactive oxygen species, can lead to skin aging, laxity, wrinkles, dryness, and coarse texture.

Molecular patterns of evolutionary changes throughout the whole nervous system of multiple nematode species.

One avenue to better understand brain evolution is to map molecular patterns of evolutionary changes in neuronal cell types across entire nervous systems of distantly related species. Generating whole-animal single-cell transcriptomes of three nematode species from the genus, we observed a remarkable stability of neuronal cell type identities over more than 45 million years of evolution. Conserved patterns of combinatorial expression of homeodomain transcription factors are among the best classifiers of homologous neuron classes.

The Clinical Profile of Heatstroke Patients Admitted to the Intensive Care Unit: A Case Series From a Tertiary Care Center in New Delhi, India.

Heat-related illnesses include a spectrum of disorders ranging from heat syncope, muscle cramps, and heat exhaustion to heat emergencies such as heatstroke. Severe heatwaves can lead to extremely high environmental temperatures and a spurt of cases of heat-related illnesses and heatstroke. The incidence of such heat-related medical emergencies was much higher in 2024 compared to previous years throughout North and Central India.

Case report: Single gene testing and comprehensive genomic profiling in non-small cell lung cancer-a case series of divergent results from a large reference laboratory.

Clinical management of non-small cell lung cancer (NSCLC) requires accurate identification of tumor-specific genetic alterations to inform treatment options. Historically, providers have relied on single-gene testing (SGT) for actionable variants due to a perception of cost-effectiveness and/or efficient turnaround time compared to next-generation sequencing (NGS). However, not all actionable variants may be evaluated through SGT modalities, and an SGT approach can exhaust valuable tissue needed for more comprehensive analyses.
