Acquired sperm hypomethylation by gestational arsenic exposure is re-established in both the paternal and maternal genomes of post-epigenetic reprogramming embryos.

Background: DNA methylation plays a crucial role in mammalian development. While methylome changes acquired in the parental genomes are believed to be erased by epigenetic reprogramming, accumulating evidence suggests that methylome changes in sperm caused by environmental factors are involved in the disease phenotypes of the offspring. These findings imply that acquired sperm methylome changes are transferred to the embryo after epigenetic reprogramming.

Background: The etiology of depression involves many biological and environmental factors, among which the inflammatory process is an important contributor. However, the role of pro-inflammatory cytokines in postmenopausal depression is unclear. Therefore, we aimed to explore the association between the serum concentrations of four pro-inflammatory cytokines (IL-1β, IL-6, IL-18, and TNF-α) and depressive symptoms in postmenopausal women who had been receiving menopause hormone therapy (MHT) for at least 6 months and postmenopausal women who had not received MHT.

January 2025
Department of Geography, Binghamton University, New York, USA.
Background: The global burden of HIV and AIDS continues to significantly impact public health, particularly in Sub-Saharan Africa. This study investigates the spatial distribution and associated risk factors of HIV prevalence in Botswana using data from the 2021 Botswana AIDS Impact Survey (BAIS V).
Methods: The analysis included 12,653 adults aged 15-64 years and employed chi-square tests, multilevel mixed-effects regression, and spatial analysis techniques.
Comparison of search and rescue operations involving emergency physicians in devastating earthquakes in Turkey: a 24-year experience study.
BMC Emerg Med
January 2025
Department of Emergency Medicine, Kartal Dr. Lutfi Kirdar City Hospital, University of Health Sciences, Istanbul, Turkey.
Background: In the 21st century, disasters (particularly earthquakes, which remain the leading cause of death) continue to be among the foremost issues requiring global emergency response. While the impact of advancing technologies on the environmental and human damage caused by earthquakes is still a subject of debate, search and rescue (SAR) teams and emergency departments (ED), specifically emergency physicians (EPs), play a crucial role in the most acute management of the effects of these earthquakes on human life. This study aims to examine the injury dynamics of two catastrophic earthquakes that occurred in Turkey 24 years apart from the perspective of EPs, utilizing archival records from the SAR teams in which EPs served.

Surface-mediated transmission of pathogens plays a key role in healthcare-associated infections. However, proper techniques for its quantitative analysis are lacking, making it challenging to develop novel antimicrobial and anti-fouling surfaces to reduce pathogen spread via environmental surfaces. This study demonstrates a gelatin hydrogel-based touch transfer test, the HydroTouch test, to evaluate pathogen transmission on high-touch surfaces under semi-dry conditions.
