Methane Bubbled Through Seawater Can be Converted to Methanol With High Efficiency.

Partial oxidation of methane (POM) is achieved by forming air-methane microbubbles in saltwater to which an alternating electric field is applied using a copper oxide foam electrode. The solubility of methane is increased by putting it in contact with water containing dissolved KCl or NaCl (3%). Being fully dispersed as microbubbles (20-40 µm in diameter), methane reacts more fully with hydroxyl radicals (OH·) at the gas-water interface.

Aurora kinase A expression in pleomorphic adenoma, adenoid cystic carcinoma, and mucoepidermoid carcinoma of salivary glands: an immunohistochemical study.

Background: Aurora kinase A (AurkA) plays a vital role in mitosis and is therefore critical in tumors development and progression. There are a few studies on AurkA expression in salivary gland tumors. The aim of the present study was to evaluate the expression pattern of AurkA in the most common benign and malignant salivary gland tumors by immunohistochemistry.

Exploring Caspase-3 overexpression in pheochromocytoma cells: Implications for cancer therapy.

Malignant pheochromocytomas are infrequent tumors that have a poorer prognosis compared to their benign counterparts. The administration of chemotherapy to patients with pheochromocytoma can result in adverse side effects and a reduced life quality. Alternative and more targeted treatment strategies, such as gene therapy significantly improve the patients' survival rate and life expectancy.

Handheld portable device for delivering capped silver nanoparticles for antimicrobial applications.

We describe a simple, cost-effective, green method for producing capped silver nanoparticles (Ag NPs) using a handheld portable mesh nebulizer. The precursor solution containing a 1:1 mixture of silver nitrate (AgNO) and ligand (glycerol or sodium alginate) was sprayed using the nebulizer. The Ag NPs were generated in the water microdroplets within a few milliseconds under ambient conditions without any external reducing agent or action of a radiation source.

As air relative humidity increases, infectivity of SARS-CoV-2 decreases within water droplets.

Water droplets containing the SARS-CoV-2 virus, responsible for coronavirus 2019 transmission, were introduced into a controlled-temperature and -humidity chamber. The SARS-CoV-2 virus with green fluorescent protein tag in droplets was used to infect Caco-2 cells, with viability assessed through flow cytometry and microscopic counting. Whereas temperature fluctuations within typical indoor ranges (20°C-30°C) had minimal impact, we observed a notable decrease in infection rate as the surrounding air's relative humidity increased.
