Enhanced RNAi does not provide efficient innate antiviral immunity in mice.

In RNA interference (RNAi), long double-stranded RNA is cleaved by the Dicer endonuclease into small interfering RNAs (siRNAs), which guide degradation of complementary RNAs. While RNAi mediates antiviral innate immunity in plants and many invertebrates, vertebrates have adopted a sequence-independent response and their Dicer produces siRNAs inefficiently because it is adapted to process small hairpin microRNA precursors in the gene-regulating microRNA pathway. Mammalian endogenous RNAi is thus a rudimentary pathway of unclear significance.

High-resolution whole-genome DNA methylation revealed unique signatures of painful diabetic neuropathy.

The aim of this work was to describe the DNA methylation signature and to identify genes associated with neuropathic pain in type 2 diabetes mellitus. We analyzed two independent diabetic neuropathy cohorts: PROPGER consisting of 72 painful and 67 painless patients recruited at the German Diabetes Center in Düsseldorf (DE), and PROPENG comprising 27 painful and 65 painless diabetic neuropathy patients recruited at the University of Manchester (UK). Genome-wide methylation data was generated using Illumina Infinium Methylation EPIC v1.

Association of corneal endothelial cell morphology with neurodegeneration in mild cognitive impairment and dementia.

Introduction: Corneal confocal microscopy (CCM) detects neurodegeneration in mild cognitive impairment (MCI) and dementia and identifies subjects with MCI who develop dementia. This study assessed whether abnormalities in corneal endothelial cell (CEC) morphology are related to corneal nerve morphology, brain volumetry, cerebral ischemia, and cognitive impairment in MCI and dementia.

Methods: Participants with no cognitive impairment (NCI), MCI, and dementia underwent CCM to quantify corneal endothelial cell density (CECD) and area (CECA), corneal nerve fiber morphology, magnetic resonance imaging (MRI) brain volumetry, and severity of brain ischemia.

Gas gangrene due to Clostridium haemolyticum in a cat with aortic thromboembolism treated using clopidogrel and rivaroxaban.

A 12-year-old Bengal cat with unclassified cardiomyopathy presented for signs consistent with aortic thromboembolism (ATE). It was treated with clopidogrel and rivaroxaban as antithrombotic therapy, combined with narcotic analgesia and frusemide. After initially making a clinical improvement, the cat's condition suddenly deteriorated, with a presumptive diagnosis of clostridial myonecrosis.

Production of sterile trout (Triploids) by chromosome set manipulation using thermal shock treatment in rainbow trout () from Kashmir Himalayas.

Rainbow trout () is a promising cultivable fish species with significant potential for expansion. As a cold-water fish belonging to the Salmonidae family, it requires an optimal temperature range of 10-15°C for optimal growth. This study explores a method for producing sterile rainbow trout with maximum survival rates by using heat shock treatment to enhance growth characteristics and improve aquaculture practices.
