Dual-targeting CRISPR-CasRx reduces C9orf72 ALS/FTD sense and antisense repeat RNAs in vitro and in vivo.

The most common genetic cause of frontotemporal dementia (FTD) and amyotrophic lateral sclerosis (ALS) is an intronic GC repeat expansion in C9orf72. The repeats undergo bidirectional transcription to produce sense and antisense repeat RNA species, which are translated into dipeptide repeat proteins (DPRs). As toxicity has been associated with both sense and antisense repeat-derived RNA and DPRs, targeting both strands may provide the most effective therapeutic strategy.

Longitudinal Follow-Up of Clinical Superficial Ovine Caseous Lymphadenitis.

Caseous lymphadenitis is an infectious disease that has a significant economic impact on sheep breeding. The objectives of this study were to evaluate the effect of season, animals' age, sex, body score and shearing on the clinical incidence of caseous lymphadenitis, relapses and abscess location in sheep from Settat province, Morocco. In this longitudinal study, 274 clinically healthy sheep were recruited in six flocks among 1451 inspected sheep and followed during 12 months to cover four seasons.

Diagnostic Challenges in Rhino-Orbito-Cerebral Mucormycosis With Diabetes Mellitus, Hypertensive Emergency, and Excess Alcohol Consumption.

A 72-year-old male with a history of excessive alcohol intake (35+ units of alcohol daily) presented to the emergency department with bilateral vision loss, periorbital swelling, headache, and sinus congestion with bloody nasal discharge. He was newly diagnosed with diabetes mellitus and presented with severe diabetic ketoacidosis and a hypertensive emergency (blood pressure of 240/90 mmHg). Despite initial normal brain and orbital imaging, the clinical presentation was complicated by multiple life-threatening conditions and a prior immunocompetent status, thereby delaying the early suspicion of mucormycosis.

Potential Role of the Tie2/ Angiopoietin System in Hepatitis C Virus- Induced Hepatocellular Carcinoma.

Background: The Tie2/Ang pathway was found to be involved in forming tumor blood vessels in various tumors. The goal of this study was to evaluate the value of Tie2/Ang pathway as a novel biomarkers for the early detection of chronic hepatitis C virus (CHC)-related hepatocellular carcinoma (HCC). And the possibility of their future application in HCC treatment.

Determination of optimum probiotic dosage for the culture of whiteleg shrimp, in an indoor system.

Determining the optimum application dosage of probiotic in biofloc system is often challenging because the microbial community seems to exert similar effects irrespective of their dosages. It is however noted that certain dosages promote higher yield in shrimp culture more effectively. Principal component analysis was adopted to identify these optimum dosages where 1-way ANOVA could not clearly identify due to the effects of microbial community.
