Changes in gut microbiota signatures associated with the epidemiological dynamics of wild European rabbits facing haemorrhagic disease outbreaks.

The new variant of rabbit haemorrhagic disease virus (RHDV2 or RHDVb) is responsible for a lethal, emerging infectious disease in several species of lagomorphs, and is globally threatening wild rabbit populations. It is known that the gut microbiota plays a crucial role in modulating host health, including immune responses and disease susceptibility. We hypothesize potential association of gut microbiota with the epidemiological dynamics of RHDV2 outbreaks that may provide key insights into how this lethal, emerging pathogen impacts wild rabbit populations.

The Role of Myxoma Virus Immune Modulators and Host Range Factors in Pathogenesis and Species Leaping.

Myxoma virus (MYXV) is a leporipoxvirus that causes lethal disease in Leporids. Hares and rabbits belong to the Leporidae family and are believed to have had a common ancestor 12 million years ago. After seventy years of contact with European hares without causing mortalities or disease manifestation, a recombinant MYXV infected Iberian hares () causing high mortalities.

Phytochemical Profile, Antioxidant Capacity, and Photoprotective Potential of Brazilian .

: The cultivation of has been encouraged in Brazil, despite the country's climate generally being unfavorable for its development. This study aimed to evaluate the chemical composition, antioxidant activity, and photoprotective potential of four varieties, Cascade, Columbus, Comet, and Nugget, cultivated in the northwestern region of Paraná State, Brazil. : The varieties were grown in experimental plots.

A Resistance Training Program on Patients with Liver Cirrhosis: A Randomized Clinical Trial.

Background: Cirrhosis represents an advanced stage of hepatic fibrosis, and the metabolic changes resulting from liver dysfunction can cause impairment in physical capacity and quality of life. This study aimed to evaluate the effect of 12 weeks of resistance exercise on inflammatory markers, oxidative stress, physical conditioning, and quality of life in patients with liver cirrhosis.

Methods: A total of 38 patients paired in the exercise (EG) and control (CG) groups participated in this study.

Epidemiological assessment of the first year of mandatory notification of chronic Chagas disease in Alagoas, Northeast Brazil.

Chagas disease (CD), caused by the protozoan parasite Trypanosoma cruzi, affects >7 million individuals worldwide. The disease progresses from an acute phase to a chronic phase, which may manifest as indeterminate, cardiac, digestive or cardiodigestive forms. Although CD is endemic in Brazil, only acute cases were subject to mandatory notification.
