December 2024
Introduction: The prevalence of germline pathogenic/likely pathogenic variants (P/LP) in high and moderate penetrance (HMP) genes is approximately 7%-10% among breast cancer (BC) patients. The prevalence and spectrum of BC P/LP variants are affected by several factors. There are limited genetic data from Brazilian patients with BC.

Nonetheless, it is crucial to understand how environmental degradation affects nest site selection and parental behaviour in female crocodilians. Therefore, our objective was to evaluate the relationship between anthropogenic disturbances and nesting behaviour in free-living broad-snouted caiman ().

- The study discovered a new genomic island (pddGI-1) in the marine pathogen Photobacterium damselae, located on chromosome II.
- This genomic island shares features with other islands in Vibrio species and consists of genes for antioxidant defense, energy metabolism, and systems that modify DNA.
- The pddGI-1 also includes a complete system for vibroferrin, which helps the bacteria thrive in low-iron environments, suggesting that strains with this island have a growth advantage in such conditions.
Article Synopsis
- Salt stress negatively impacts plant growth, prompting researchers to explore Ca-complex sources as a way to mitigate these effects in sour passion fruit seedlings.
- The study involved a randomized block design with different cultivars, salinity levels, and Ca-complex sources to assess their impact on various physiological traits over 60 days.
- Results indicated that using Ca-complex sources, particularly those with amino acids, significantly improved water use efficiency and reduced cell membrane damage, suggesting their effectiveness in supporting plant health under moderate salinity stress.
Unlabelled: The gut microbiome has the potential to buffer temporal variations in resource availability and consumption, which may play a key role in the ability of animals to adapt to a broad range of habitats. We investigated the temporal composition and function of the gut microbiomes of wild common marmosets () exploiting a hot, dry environment-Caatinga-in northeastern Brazil. We collected fecal samples during two time periods (July-August and February-March) for 2 years from marmosets belonging to eight social groups.
