Thermal niches and activity periods in syntopic Phymaturus and Liolaemus lizards from the Andes, Argentina
An Acad Bras Cienc. 2024 Feb 12;96(1):e20191190. doi: 10.1590/0001-3765202320191190. eCollection 2024.ABSTRACTExplanations for differences in thermal biology within and between species of lizards employ concepts of phylogenetic inertia and plasticity. We compared the thermal biology of three liolaemid species in the Andean highlands in Argentina: two allopatric congeners (Phymaturus williamsi and P. aguanegra) each in syntopy with Liolaemus parvus. We predicted intra and inter-generic differences in ecophysiological traits and periods of activity at both sites, ecotypic differences between the (labile) Liolaemus population...

Self-reported clinical features and treatment effectiveness of Papillon-Lef èvre syndrome patients from five Latin American countries: A cross-sectional online survey study
CONCLUSIONS: The study's results align with prior research on PLS, but reveal new insights, including the impact on patients' quality of life and a history of delayed umbilical cord separation. These findings warrant consideration in future research and patient care.PMID:38351550 | DOI:10.1111/ajd.14219 (Source: The Australasian Journal of Dermatology)

First winter record of Latrodectus mirabilis (Araneae: Theridiidae) in arid Patagonia: a consequence of climate change and urbanization?
Acta Trop. 2024 Feb 10:107147. doi: 10.1016/j.actatropica.2024.107147. Online ahead of print.ABSTRACTCases of araneism reported in the province of Chubut (Argentina) have tripled in the last two decades, and almost 80 % of them involve Latrodectus mirabilis (Holmberg) (Araneae: Theridiidae). According to descriptions of the life cycle of this species in Argentina, the low temperatures typical of autumn-winter cause the death of all adult spiders, so that no adult specimens of L. mirabilis are observed in winter. Field samplings, observations by the Grupo de Entomología Patagónica (GENTPAT, IPEEC CCT CENPAT CONICET), and ...

Genetic susceptibility for retinopathy of prematurity and its associated comorbidities
CONCLUSION: We identified three maternal and three perinatal risk factors associated with ROP. Genes EPAS1 and AGTR1, involved in angiogenesis and vascularization, were identified to be of risk for ROP.IMPACT: Genetic and environmental risk factors associated with ROP and its comorbidities are evaluated in a Latin American population. Genes EPAS1 and AGTR1, involved in angiogenesis and vascularization, were identified to be of risk for ROP. Three maternal and three perinatal risk factors associated with ROP were also identified. A matrix of significant relationships among genetic markers and comorbidities is presented. Rep...

Nutrient structure dynamics and microbial communities at the water –sediment interface in an extremely acidic lake in northern Patagonia
Lake Caviahue (37° 50 ‘S and 71° 06’ W; Patagonia, Argentina) is an extreme case of a glacial, naturally acidic, aquatic environment (pH ~ 3). Knowledge of the bacterial communities in the water column of this lake, is incipient, with a basal quantification of the bacterioplankton abundance distribution in the North and South Basins of Lake Caviahue, and the described the presence of sulfur and iron oxidizing bacteria in the lake sediments. The role that bacterioplankton plays in nutrient utilization and recycling in this environment, especially in the phosphorus cycle, has not been studied. In this work, we expl...

IJERPH, Vol. 21, Pages 214: Mental Health Professionals & rsquo; Perception of Respect for Human Rights and Organizational Well-Being in Three Countries of South America
This study assesses the perception of the respect for human rights for users and staff, as well as organizational and job satisfaction among mental health professionals in three South American countries, through the well-being at work and respect for human rights (WWRR) questionnaire and assesses whether there are significant differences. Seven mental health facilities in Argentina, Colombia, and Peru were involved in this observational study. The sample comprised 310 mental health professionals. The three countries exhibited differences in WWRR, particularly in the staff&rsquo;s satisfaction with resources for car...
