Greater male variability in daily energy expenditure develops through puberty
Biol Lett. 2023 Sep;19(9):20230152. doi: 10.1098/rsbl.2023.0152. Epub 2023 Sep 20.ABSTRACTThere is considerably greater variation in metabolic rates between men than between women, in terms of basal, activity and total (daily) energy expenditure (EE). One possible explanation is that EE is associated with male sexual characteristics (which are known to vary more than other traits) such as musculature and athletic capacity. Such traits might be predicted to be most prominent during periods of adolescence and young adulthood, when sexual behaviour develops and peaks. We tested this hypothesis on a large dataset by comparing ...

Phylogenomics of weevils revisited: data curation and modelling compositional heterogeneity
Biol Lett. 2023 Sep;19(9):20230307. doi: 10.1098/rsbl.2023.0307. Epub 2023 Sep 20.ABSTRACTWeevils represent one of the most prolific radiations of beetles and the most diverse group of herbivores on land. The phylogeny of weevils (Curculionoidea) has received extensive attention, and a largely satisfactory framework for their interfamilial relationships has been established. However, a recent phylogenomic study of Curculionoidea based on anchored hybrid enrichment (AHE) data yielded an abnormal placement for the family Belidae (strongly supported as sister to Nemonychidae + Anthribidae). Here we reanalyse the genome-scale ...

The interactome of the UapA transporter reveals putative new players in anterograde membrane cargo trafficking
Fungal Genet Biol. 2023 Sep 18:103840. doi: 10.1016/j.fgb.2023.103840. Online ahead of print.ABSTRACTNeosynthesized plasma membrane (PM) proteins co-translationally translocate to the ER, concentrate at regions called ER-exit sites (ERes) and pack into COPII secretory vesicles which are sorted to the early-Golgi through membrane fusion. Following Golgi maturation, membrane cargoes reach the late-Golgi, from where they exit in clathrin-coated vesicles destined to the PM, directly or through endosomes. Post-Golgi membrane cargo trafficking also involves the cytoskeleton and the exocyst. The Golgi-dependent secretory pathway ...

Exhaustive exercise alters native and site-specific H < sub > 2 < /sub > O < sub > 2 < /sub > emission in red and white skeletal muscle mitochondria
Free Radic Biol Med. 2023 Sep 18:S0891-5849(23)00642-1. doi: 10.1016/j.freeradbiomed.2023.09.018. Online ahead of print.ABSTRACTMitochondrial reactive oxygen species (ROS) homeostasis is intricately linked to energy conversion reactions and entails regulation of the mechanisms of ROS production and removal. However, there is limited understanding of how energy demand modulates ROS balance. Skeletal muscle experiences a wide range of energy demand depending on the intensity and duration of exercise and therefore is an excellent model to probe the effect of altered energy demand on mitochondrial ROS production. Because in mo...

Glutaredoxin proteins from E. coli isoforms were compared in terms of energy frustration
In this study, we have investigated the energy landscape and characterized the pattern of local frustration in different forms and states of the GRX protein ofE. coli.Analysis was done on the conformational alterations, significant changes in the frustration pattern, and different GRXs such as GRX-II, GRX-III, GRX-II-GSH, and GRX-III-GSH complex. We have found the practice of frustration, and structure was quite similar in the same isoform having different states of protein; however, a significant difference was observed between different isoforms. Moreover, oxidation of GRX-I introduced an extra α-helix increasing the de...

Unonopsis guatterioides: morphological and chemical characteristics of its fruits and seeds, and germination processes under experimental conditions
This study aimed to evaluate the morphometry of seeds and fruits, their chemical composition, and the germination at different temperatures using seeds subjected to tegumentary dormancy break from fruits collected in a semi-deciduous seasonal forests in Mato Grosso do Sul, Brazil. The fruits under ripening showed a higher number of secondary metabolites and higher phenolic compounds. Morphometry results indicated that most seeds have length between 3.5 and 5.6 (81.3%), width between 8.1 and 9.0 mm (85.0%) and average weight of 0.28 g. The results indicate that there is a greater number of fruits with length ranging between...

Gill and hepatic histological alterations in Sciades herzbergii resulting from trace element contamination in the Port of S ão Luiz, Brazil
The objective of this study was to evaluate, through changes in the gills and livers of Sciades herzbergii, the environmental contamination to which estuarine organisms are exposed in two areas in São Marcos Bay - MA. Two collection areas located in São Marcos Bay were selected for this study: A1, an area close to the Port Complex, and A2, an area on Caranguejos Island (included in the Environmental Protection Area of Baixada Maranhense). Collections were carried out during rainy and dry periods. Sediments (for trace element analyses), surface water (for physico-chemical analyses), and specimens of S. herzbergii (for bio...

Oysters are animals that filter water to obtain oxygen and nutrients. In this process, they can bioaccumulate microorganisms and chemical substances in their tissues. The growth of mollusk culture in Northeastern Brazil requires the health identification of cultivated oysters through the quantification of the ...

Immunostimulating activity of Uncaria tomentosa in RAW 264.7 macrophages
Braz J Biol. 2023 Sep 15;83:e271339. doi: 10.1590/1519-6984.271339. eCollection 2023.ABSTRACTUncaria tomentosa is a plant native to the Amazon that has immunomodulatory and antitumor properties due to the alkaloids found in the plant, being able to modify the immune response by potentiating or suspending the action of cytokines secreted by macrophages that induce the immune response, either by the classical route (M1) or through the alternative route (M2). Macrophages activated by M1 convert L-arginine into L-citrulline and nitric oxide (NO), whereas macrophages activated by the M2 pathway use the enzymatic activity of arg...

A food interaction network between psittacines and plants in an urban area in the city of S ão Carlos - SP, southeastern Brazil
Braz J Biol. 2023 Sep 15;83:e269353. doi: 10.1590/1519-6984.269353. eCollection 2023.ABSTRACTThe Psittacidae presents a great diversity of species in the Neotropical region performing fundamental ecological functions for ecosystems. These frugivorous birds can occupy different positions in the antagonistic-mutualistic gradient of food interactions, acting as predators and/or as seed dispersers. Little is known about bird-plant ecological interaction networks focusing on psittacines in urban environments, which may compromise the management of natural areas in anthropic landscapes and hinder the planning of conservation str...

The importance of omega-3 polyunsaturated fatty acids as high-quality food in freshwater ecosystems with implications of global change
Biol Rev Camb Philos Soc. 2023 Sep 19. doi: 10.1111/brv.13017. Online ahead of print.ABSTRACTTraditionally, trophic ecology research on aquatic ecosystems has focused more on the quantity of dietary energy flow within food webs rather than food quality and its effects on organisms at various trophic levels. Recent studies emphasize that food quality is central to consumer growth and reproduction, and the importance of food quality for aquatic ecosystems has become increasingly well recognized. It is timely to synthesise these findings and identify potential future research directions. We conducted a systematic review of om...
