Inter-Island Variability in Trace Elements and Trophic Ecology of Brown Booby (Sula leucogaster) in the South Atlantic.

This study investigates essential (Mg, Ca, Fe, Mn, Cu, Zn, Se, Ni) and non-essential (Li, Be, Cr, Rb, Sr, Cs, Cd, Sn, Ba, and Pb) element concentrations and stable isotope (δC, δN, δS) compositions in feathers of Brown Boobies (Sula leucogaster) from three distinct Atlantic islands: the Archipelagos of Saint Peter and Saint Paul (SPSP), Abrolhos, and Cagarras. We aimed to investigate the ecological and environmental factors influencing these seabird populations and assess potential variations in contaminant exposure and dietary habits based on location, sex, and maturity stages. Our finding revealed significant geographical differences in trace element concentrations.

Sleep complaints in individuals with SYNGAP1-associated syndrome.

Neurodevelopmental disorders pose significant clinical challenges related to atypical brain development, often manifesting as learning disabilities, developmental delays, intellectual deficits, behavioral issues, epilepsy, and sleep disturbances. Among genetic neuropsychiatric conditions, synaptopathies are notable for their impact on synaptic function, resulting in varied neuropsychiatric phenotypes. Among these, SYNGAP1-associated syndrome is characterized by intellectual disability, global developmental delay, autism, and epilepsy, primarily due to loss-of-function mutations.

On the parameterized complexity of the median and closest problems under some permutation metrics.

Genome rearrangements are events where large blocks of DNA exchange places during evolution. The analysis of these events is a promising tool for understanding evolutionary genomics, providing data for phylogenetic reconstruction based on genome rearrangement measures. Many pairwise rearrangement distances have been proposed, based on finding the minimum number of rearrangement events to transform one genome into the other, using some predefined operation.

Chronic noncommunicable diseases and absenteeism from work: National Survey of Health, 2019.

Objective: To evaluate the association between burden of disease and multimorbidity and absenteeism in Brazil.

Methods: This is a cross-sectional study using data from the National Survey of Health 2019. The assessed outcome was absenteeism from work.
