Wetlands are a major source of methane emissions and contribute to the observed increase in atmospheric methane over the last 20 years. Methane production in wetlands is the final step of carbon decomposition performed by anaerobic archaea. Although hydrogen/carbon dioxide and acetate are the substrates most often attributed to methanogenesis, other substrates - such as methylated compounds - may additionally play important roles in driving methane production in wetland systems.

Introduction: The superficial musculoaponeurotic system (SMAS) is an acronym describing a facial subcutaneous anchored three-dimensional (3D) fibro-adipose-muscular tissue network connected to mimic muscles. SMAS transfers, distributes and reinforces mimic facial muscles contractions to the skin determining mimic expression and facial fold formation. The aim of this study was the histomorphological analysis of prenatal SMAS (pre-SMAS) development in analogy to the adult SMAS typology.

Despite significant advances in microbiome research across various environments, the microbiome of Earth's largest biomass reservoir-the wood of living trees-remains largely unexplored. Here, we illuminate the microbiome inhabiting and adapted to wood and further specialized to individual host tree species, revealing that wood is a harbour of biodiversity and potential key players in tree health and forest ecosystem functions. We demonstrate that a single tree hosts approximately one trillion bacteria in its woody tissues, with microbial communities distinctly partitioned between heartwood and sapwood, each maintaining unique microbiomes with minimal similarity to other plant tissues or ecosystem components.

Amyotrophic lateral sclerosis (ALS) is a progressive motor neuron disease that causes loss of upper and lower motor neurons, leading to muscle weakness and ultimately death. This review highlights recent advancements in Neuromuscular Medicine and Physical Medicine and Rehabilitation (PM&R), emphasizing innovations in the diagnosis, treatment, and care delivery for ALS. The field of PM&R emphasizes a multidisciplinary, patient-centered approach, incorporating advanced diagnostic tools, therapeutic strategies, adaptive equipment, and telerehabilitation to optimize function.

Background: A large proportion of prostate cancer (PCa) patients also report being anxious, which can impede their recovery and adversely influence their personal relationships.

Aims: In order to better understand the relationships between symptoms of anxiety in these men, with a view towards more informed treatments for anxiety, the network structure of the symptomatology for Generalised Anxiety Disorder (GAD) was examined in this study.

Methods: A total of 425 PCa patients completed the GAD-7 and an extended version of that inventory (the GAD-10).
