Abstract

Patulin was tested for stability at pH values of 6.0, 6.5, 7.0, 7.5, and 8.0, using Sörensen's phosphate buffer at 25 degrees C. Patulin was determined by high-performance liquid chromatography. When the percentage of patulin remaining was plotted versus reaction time, apparent first-order reaction plots were obtained. Reaction rate constants for disappearance of patulin ranged from 1.1 x 10(-2) h at pH 8.0-5.3 x 10(-4) h at pH 6.0. Values for half-life were calculated and ranged from 64 h at pH 8.0 to 1310 h at pH 6.0.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Sexual Dimorphism in Neurodegeneration

There exist sex differences in neurodevelopmental and neurodegenerative disorders. For instance, multiple sclerosis is more common in women, whereas Parkinson’s disease is more common in men. Here is the latest research on sexual dimorphism in neurodegeneration
