Triatoma infestans (Hemiptera: Reduviidae) Population Genetics: What Have We Learned from Microsatellites?
AbstractPurpose of ReviewThe genetic structure of insect vectors offers valuable insights for identifying panmictic units, reinfestation sources, and minimal intervention units in vector control programs. This review highlights key findings on the genetic structure ofTriatoma infestans populations using microsatellites across various geographic scales and landscapes.Recent FindingsMicrosatellites have been employed to explore the genetic structure ofT. infestans across Argentina, Bolivia, Paraguay, Brazil, and Peru. Research has focused on understanding genetic structure, assessing the impacts of short and long-distance mi...

Impacts of horticultural environments on Rhinella arenarum (Anura, Bufonidae) populations: exploring genocytotoxic damage and demographic life history traits
This study aimed to assess genocytotoxic damage and demographic life history traits of R. arenarum inhabiting horticultural environments. Sampling was conducted in suburban sites in central Argentina: H1 and H2 (sites associated with horticultural activity) and a reference site, RS. Environmental parameters were recorded, and the frequency of micronuclei (Mn), nuclear abnormalities (ENA), and indicators of cytotoxic damage were determined in tadpoles and adults. Demographic variables (age at maturity, longevity, potential reproductive lifespan, size at maturity, modal lifespan) were calculated. The highest nitrate and phos...

Online ahead of print.ABSTRACTBACKGROUND: Exacerbation frequency strongly influences treatment choices in patients with severe asthma.RESEARCH QUESTION: What is the extent of the variability of exacerbations rate across countries and its implications in disease management?STUDY DESIGN AND METHODS: We retrieved data from the International Severe Asthma Registry, an international observational cohort of patients with a clinical diagnosis of severe asthma. We identified patients aged ≥18 years who did not initiate any biologics prior to baseline vis...

Effect of acute cadmium exposure on oxidative stress and antioxidant system of the scallop Aequipecten tehuelchus
This study aimed to assess the impact of acute exposure (96 h) to Cd in gills, digestive gland and muscle of the Tehuelche scallop Aequipecten tehuelchus from San José gulf in Patagonia, Argentina. Scallops were exposed to Cd concentrations of 0, 25, 50, 100, 150, 204, 275, 371, and 500 μg/L, and mortality rates were recorded after 96 h of exposure. Surviving organisms were analyzed for the biochemical response through reactive oxygen and nitrogen species (RONS), activities of catalase (CAT) and glutathione-S-transferase (GST), metallothioneins (MT), lipid peroxidation (LPO) and liposoluble antioxidants α-tocopherol (α...
