A bienzymatic sensor for the determination of phosphate was constructed by coimmobilization of xanthine oxidase (EC 1.2.3.22) and nucleoside phosphorylase (EC 2.4.2.1) on a polycarbonate membrane mounted on the tips of amperometric hydrogen peroxide and oxygen electrodes. The sensor response was linear to phosphate concentrations in the range 10-250 microM.

Objective: Caveolae are closely linked to the onset and progression of atherosclerosis. The pivotal involvement of caveolin-1 (CAV1) within the caveolae in atherosclerosis development has been consistently supported. However, the potential contributions of additional caveolae proteins to atherosclerosis necessitate further exploration.

The COVID-19 pandemic has led to significant societal disruptions, prompting the Indonesian government to implement various measures, including partial lockdowns or Community Activities Restrictions Enforcement (CARE), to curb the virus's spread. This research aims to assess the impact of various environmental parameters on Cirebon's estuaries, focusing on physical components (such as temperature, total solids [TS], and turbidity), chemical components (including pH, biochemical oxygen demand (BOD), dissolved oxygen (DO), nitrate, and phosphate), and microbiology components (specifically total coliforms). These comprehensive components have notably impacted environmental parameters during pre-, during, and post-COVID-19 pandemic based on the Water Quality Index (WQI) assessment in Cirebon's estuaries.

The most common mechanism of the development of cardiovascular diseases is atherosclerosis, caused by genetic predisposition, hyperlipidemia, inflammation and metabolic disorders. Statins used in medicine inhibit endogenous cholesterol synthesis, but are characterized by diabetogenic effect, development of intolerance in 9.1%, and muscle symptoms in 10-25% of patients.

Polyamines are key signalling and substrate molecules that are made by all organisms. The polyamine known as spermidine is typically made by spermidine synthase, but in many bacterial species, including 70% of human gut microbes, carboxyspermidine decarboxylase (CASDC) performs the terminal step in the production of spermidine. An X-ray crystal structure of CASDC from the human gut microbe Clostridium leptum has been solved by molecular replacement at a resolution of 1.
