Introduction Male hypogonadism, including age-related and functional forms, is characterized by insufficient testosterone production often associated with obesity and metabolic comorbidities. Testosterone replacement therapy (TRT) increases serum testosterone but suppresses spermatogenesis and may cause adverse effects. Selective estrogen receptor modulators (SERMs), such as clomiphene citrate, have emerged as an alternative a...

Aim We investigate the distribution of dispersal modes — endozoochory (via animal ingestion), synzoochory (via animal seed accumulation) and anemochory (via wind)—and seed mass of woody plants across Brazilian ecosystems, testing whether their relative abundance in local plant communities could be predicted by climate, edaphic factors and dispersal agents (e.g., the main vectors moving seeds). We expected climate to be the mai...

Hepatitis E virus (HEV) is currently recognized as an emerging problem and a growing concern for public health in developed countries, with HEV infections mainly attributable to foodborne transmission of HEV-3. The zoonotic HEV genotype 3 infects a wide range of mammalian hosts, with swine considered as the primary host. This study investigates the occurrence of HEV among small ruminants in Portugal. The primary aim of the pre...
