Improved protocol for high-quality co-extraction of DNA and RNA from rumen digesta

We report an improved method for total nucleic acids extraction from rumen content samples. The method employs bead beating, and phenol-chloroform extraction followed by saline-alcohol precipitation. Total nucleic acids and RNA yield and purity were assessed by spectrophotometric measurements; RNA integrity was estimated using Agilent RNA 6000 Nano Kit on an Agilent 2100 Bioanalyzer. The method provided total nucleic acids and RNA extracts of good quantity and quality. The extraction is not time consuming and it is valuable for ecological studies of rumen microbial community structure and gene expression.

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

HLA Genetic Variation

HLA genetic variation has been found to confer risk for a wide variety of diseases. Identifying these associations and understanding their molecular mechanisms is ongoing and holds promise for the development of therapeutics. Find the latest research on HLA genetic variation here.

Super-resolution Microscopy

Super-resolution microscopy is the term commonly given to fluorescence microscopy techniques with resolutions that are not limited by the diffraction of light. Here are the latest discoveries pertaining to super-resolution microscopy.
