< em > HLA-G < /em > 14 bp Ins/Del (rs66554220) Variant Is Not Associated with Breast Cancer in Women from Western Mexico
In conclusion, the 14-bp Ins/Del (rs66554220) variant of HLA-G is not associated with BC in the Mexican population, but might be related to advanced breast tumors. Further studies are required.PMID:37623251 | PMC:PMC10453716 | DOI:10.3390/cimb45080432

Growing Feminization of Migration in Cuba Poses New Challenges
By Luis BrizuelaHAVANA, Aug 25 2023 (IPS) Emigrating from Cuba was an agonizing decision for Ana Iraida. She left behind family and friends; in her backpack she carried many hopes, but also the fear of facing dangers on the journey to the United States.
“My salary and that of my second job, as an editor, were insufficient. I wanted to prosper and help my parents. Nor did I want to have a child in a country where it is an ordeal to buy everything from disposable diapers to soap, not to mention food,” the 33-year-old philologist who, like the others interviewed for this story, asked to withhold her last name, tol...

Plant growth-promoting and heavy metal-resistant Priestia and Bacillus strains associated with pioneer plants from mine tailings
Arch Microbiol. 2023 Aug 24;205(9):318. doi: 10.1007/s00203-023-03650-5.ABSTRACTOpen mine tailings dams are extreme artificial environments containing sizeable potentially toxic elements (PTEs), including heavy metals (HMs), transition metals, and metalloids. Furthermore, these tailings have nutritional deficiencies, including assimilable phosphorus sources, organic carbon, and combined nitrogen, preventing plant colonization. Bacteria, that colonize these environments, have mechanisms to tolerate the selective pressures of PTEs. In this work, several Priestia megaterium (formerly Bacillus megaterium), Bacillus mojavensis,...

Global squid contamination by halogenated polycyclic aromatic hydrocarbons and its trade induced risk transfer
Environ Int. 2023 Aug 19;179:108163. doi: 10.1016/j.envint.2023.108163. Online ahead of print.ABSTRACTSquid is traded globally as an important food resource. However, the occurrence of carcinogenic halogenated polycyclic aromatic hydrocarbons (HPAHs) in squid and the risk of their transfer through trade is little understood or recognized. Here, we comprehensively evaluated the occurrence and risk transfer by quantifying the congener-specific concentrations of HPAHs in 121 squid samples collected from the Pacific, Atlantic and Indian oceans. This was the first time that nine of the 36 target chlorinated and brominated PAH c...

White adipose tissue: Distribution, molecular insights of impaired expandability, and its implication in fatty liver disease
Biochim Biophys Acta Mol Basis Dis. 2023 Aug 21:166853. doi: 10.1016/j.bbadis.2023.166853. Online ahead of print.ABSTRACTWe are far behind the 2025 World Health Organization (WHO) goal of a zero increase in obesity. Close to 360 million people in Latin America and the Caribbean are overweight, with the highest rates observed in the Bahamas, Mexico, and Chile. To achieve relevant progress against the obesity epidemic, scientific research is essential to establish uniform practices in the study of obesity pathophysiology (using pre-clinical and clinical models) that ensure accuracy, reproducibility, and transcendent outcomes...

Coupled Oscillators in an Agroecosystem: Integrating Direct and Indirect Effects
Am Nat. 2023 Sep;202(3):288-301. doi: 10.1086/725439. Epub 2023 Jul 20.ABSTRACTAbstractAgricultural pests are increasingly appreciated as subjects of ecology. One particular case, a pest in coffee production, is analyzed here using the conceptual framework of complex systems, increasingly acknowledged as having an obvious home in the field of ecology, notorious for its complex structures. The particular case analyzed here arguably falls under the control of the complexity of the ecological system rather than of a simple magic bullet of population regulation. The system, which has been under study in southern Mexico for the...

Maternal exposure to metal components of PM < sub > 2.5 < /sub > and low birth weight in New Mexico, USA
This study identified the associations between maternal exposure to 10 metal components of PM2.5 and LBW in offspring based on small area (divided by population size) level data in New Mexico, USA, from 2012 to 2016. This study used a pruned feed-forward neural network (pruned-FNN) approach to estimate the annual average exposure index to each metal component in each small area. The linear regression model was employed to examine the association between maternal PM2.5 metal exposures and LBW rate in small areas, adjusting for the female percentage and race/ethnicity compositions, marriage status, and educational level in t...

Changes in the abundance and diversity of bacterial and archaeal communities at different depths in a eutrophic freshwater lake in southwestern Mexico
In this study, 3 sites were evaluated; samples were collected using 0-15 m deep water columns and analyzed using Illumina MiSeq sequencing technology based on the 16S rRNA gene. The physical parameters of pH, temperature, dissolved oxygen, electrolytic conductivity, and PO-4 were determined. The results revealed clear differences in the microbial composition of the water throughout the column; the most abundant phyla in bacterial communities were Proteobacteria (23.2%), Cyanobacteria (17.3%), and Bacteroidetes (17.2%), and for archaea were Crenarchaeota (35.9%) and Euryarchaeota (33.2%). PICRUSt metabolic inference analysi...
