Urbanisation stands as a primary driver of biodiversity loss globally, reshaping natural landscapes and imposing novel environmental conditions upon organisms. This ecological novelty poses challenges, and species capable of thriving in urban environments are considered tolerant. Among vertebrates, anurans are the most susceptible to land-use changes, mainly due to their life history and morphological traits.

The aim of this study was to analyze the effectiveness of colonoscopy within an opportunistic screening program using nested case-control study.
Methods: Subjects who received a diagnosis of CRC (CG) between the ages of 50 and 90 years were included and matched by age and gender in a 1:5 ratio with patients without CRC diagnosis (COG) during the period 2015 to 2023.
Background: Different diets have emerged as potential therapeutic options for patients with irritable bowel syndrome (IBS).
Objective: To identify predictors of improvement after a low-FODMAP, low-starch and low-sucrose diet among patients with IBS.
Methods: We performed a descriptive cross-sectional study including patients with IBS according to Rome IV criteria undertaking a social-media based program with a two-week dietary intervention.
Article Synopsis
- Mitochondria and lysosomes are interdependent organelles that affect each other's functions, where defects in one lead to issues in the other.
- Recent research using RNA sequencing has revealed that mitochondrial defects lead to downregulation of cholesterol synthesis pathways, while lysosomal defects lead to their upregulation.
- The study also identified the role of the transcription factor SREBF1 in this regulation and demonstrated that balancing calcium levels in lysosomes can alleviate some developmental issues linked to mitochondrial dysfunction in a model organism, C. elegans.
Background: Irritable bowel syndrome (IBS) is a functional disorder commonly associated with extra-intestinal symptoms. However, the prevalence of these symptoms according to IBS subtype is not well established.
Aim: To compare the prevalence of extra-intestinal symptoms among patients with different subtypes of IBS.
