Article Synopsis
  • Cyanobacteria, specifically the Neowestiellopsis persica A1387 strain, show promise as an eco-friendly method for removing heavy metals like nickel when treated with plasma-activated water (PAW).
  • The study found that a 15-minute exposure to plasma yielded the best results in terms of biomass, polysaccharide content, and nickel removal efficiency, based on statistical analysis.
  • Further analysis revealed that longer plasma treatment increased certain chemical compounds in the cyanobacteria and contributed to unique structural changes, although excessive treatment durations led to decreased efficiency due to increased reactive oxygen species.

Background: Freezing is a crucial technique in reproductive science utilized for the preservation of sperm samples. However, the process of freezing and thawing sperm can result in detrimental effects on sperm quality. One of the major mechanisms underlying this decline in sperm quality is the generation of reactive oxygen species during the freeze process.

Developing a suitable index for Waste Load Allocation (WLA) is essential for both industrial polluters and environmental organizations. Identifying the index that best describes the quality conditions of the river is the main concern of this study. To achieve this purpose, a novel framework incorporating a regret-based index and a bankruptcy-based approach to address the impacts of low water quality and pollutant locations within the WLA are introduced.

Diagnosis of diseases with low facilities, speed, accuracy and sensitivity is an important matter in treatment. Bioprobes based on iron oxide nanoparticles are a good candidate for early detection of deadly and infectious diseases such as tetanus due to their high reactivity, biocompatibility, low production cost and sample separation under a magnetic field. In this study, silane groups were coated on surface of iron oxide nanoparticles using tetraethoxysilane (TEOS) hydrolysis.

Celiac disease (CD) is a complex disorder influenced by genetic and environmental factors. When people with a genetic predisposition to CD consume gluten, an inflammatory response is triggered in the small intestine, and this reaction can be alleviated by the elimination of gluten from the diet. The clinical manifestations of CD vary greatly from person to person and begin at a young age or in adulthood.

Background: Lung cancer is a major cause of cancer-related mortality worldwide, with a 5-year survival rate of approximately 22%. Cisplatin is one of the standard first-line chemotherapeutic agents for non-small cell lung cancer (NSCLC), but its efficacy is often limited by the development of resistance. Despite extensive research on the molecular mechanisms of chemoresistance, the underlying causes remain elusive and complex.

Photodynamic therapy (PDT) is an innovative, non-invasive method of treating cancer that uses light-activated photosensitizers to create reactive oxygen species (ROS). However, challenges associated with the limited penetration depth of light and the need for precise control over photosensitizer activation have hindered its clinical translation. Nanomedicine, particularly gold nanobiostructures, offers promising solutions to overcome these limitations.
