Randomized controlled trial on the efficacy of forest walking compared to urban walking in enhancing mucosal immunity.

Scientific research on forest therapy's preventive medical and mental health effects has advanced, but the need for clear evidence for practical applications remains. We conducted an unblinded randomized controlled trial involving healthy men aged 40-70 to compare the physiological and psychological effects of forest and urban walking. Eighty-four participants were randomly assigned to either the forest or urban group, with 78 completing 90-min walks and analysis.

Background/objectives: The effect of maternal macronutrient composition on the risk of large for gestational age (LGA) neonates among women with gestational diabetes mellitus (GDM) is not well understood. This study aimed to investigate these associations in a pregnant cohort in Northern Greece, considering both pre-pregnancy and early pregnancy dietary intake, and stratifying women by pre-pregnancy body mass index (BMI).
Methods: From a total of 797 eligible pregnant women, the 117 (14.
Resolving spatiotemporal dynamics in bacterial multicellular populations: approaches and challenges.

SUMMARYThe development of multicellularity represents a key evolutionary transition that is crucial for the emergence of complex life forms. Although multicellularity has traditionally been studied in eukaryotes, it originates in prokaryotes. Coordinated aggregation of individual cells within the confines of a colony results in emerging, higher-level functions that benefit the population as a whole.

Greenhouse gas (GHG) emissions are creating unprecedented climate-driven extreme weather, with levels of heat and humidity surpassing human physiological tolerance for heat stress. These conditions create a risk of mass casualties, with some populations particularly vulnerable due to physiological, behavioural and socioeconomic conditions (eg, lack of adequate shelter, limited healthcare infrastructure, sparse air conditioning access and electrical grid vulnerabilities). Children, especially young children, are uniquely vulnerable to extreme heat-related morbidity and mortality due to factors including low body mass, high metabolism, suboptimal thermoregulatory mechanisms and behavioural vulnerabilities.

Botulinum neurotoxins (BoNTs) rank among the most potent toxins and many of them are produced by bacteria carrying the orfX gene cluster that also encodes four nontoxic proteins (OrfX1, OrfX2, OrfX3 and P47). The orfX gene cluster is also found in the genomes of many non-BoNT-producing bacteria, often alongside genes encoding oral insecticidal toxins. However, the functions of these OrfXs and P47 remain elusive.
