RNA extraction is a critical step in gene expression analysis. While numerous RNA extraction kits are commercially available, most kits cannot be utilized for RNA extraction from rice endosperm that contains abundant starch. Here, I describe a three-step RNA extraction from rice starchy endosperm. The process involves phenol/chloroform extraction, ethanol precipitation, and lithium chloride precipitation. This method yields an abundant and high-quality total RNA even from a single starchy endosperm.

Crimean-Congo haemorrhagic fever virus (CCHFV), a Biosafety level 4 pathogen transmitted by ticks, causes severe haemorrhagic diseases in humans but remains clinically silent in animals. Over the past forty years, Nigeria lacks comprehensive genetic data on CCHFV in livestock and ticks. This study aimed to identify and characterize CCHFV strains in cattle and their Hyalomma ticks, the primary vector, in Kwara State, Nigeria.

Glucocorticosteroids remain the most common pharmaceutical approach for the treatment of equine asthma but can be associated with significant side effects, including respiratory microbiome alterations. The goal of the study was to assess the impact of 2% lidocaine nebulization, a projected alternative treatment of equine asthma, on the healthy equine respiratory microbiota. A prospective, randomized, controlled, blinded, 2-way crossover study was performed, to assess the effect of 1 mg/kg 2% lidocaine (7 treatments over 4 days) on the equine respiratory microbiota compared to control horses (saline and no treatment).

Background: Multiplex genetic testing is recommended when treating nonsmall cell lung cancer. A certain percentage of test failures in RNA assays owing to poor surgical specimen quality have been documented, and fixation failure is a possible cause. At our institution, sheet-like fixation is performed to reduce fixation time.

spp. are common zoonotic intestinal protozoa, which can lead to serious intestinal diseases in both humans and animals through fecal-oral transmission, leading to significant economic losses and public health challenges. To reveal the prevalence of in sheep and cattle in Shanxi Province, North China, fecal samples were collected from 311 sheep, 392 dairy cattle, and 393 beef cattle from three representative counties in the northern, central, and southern regions of Shanxi Province.
