Central Taxa Are Keystone Microbes During Early Succession.

Microorganisms underpin numerous ecosystem processes and support biodiversity globally. Yet, we understand surprisingly little about what structures environmental microbiomes, including how to efficiently identify key players. Microbiome network theory predicts that highly connected hubs act as keystones, but this has never been empirically tested in nature.

A Rare Case of a Malignant Proliferating Trichilemmal Tumor: A Molecular Study Harboring Potential Therapeutic Significance and a Review of Literature.

Malignant proliferating trichilemmal tumors (MPTTs), arising from the external root sheath of hair follicles, are exceptionally rare, with limited documentation of their genetic alterations. We present a case of a 64-year-old African American woman who initially presented with a gradually enlarging nodule on her posterior scalp. An initial biopsy at an outside hospital suggested metastatic adenocarcinoma or squamous cell carcinoma (SCC) of an uncertain origin.

Metabolic syndrome, non-alcoholic fatty liver disease and graft inflammation: an unaddressed pathogenic link after kidney transplantation.

Kidney transplantation (KT) is the treatment of choice for chronic kidney disease (CKD) patients, but there is a continued loss of grafts in the long-term (50% at 10 years) due to either patient 's death or chronic allograft dysfunction. Metabolic syndrome (MS) is very prevalent after KT (30-40%) and its components contribute to the appearance of non-alcoholic fatty liver disease/metabolic dysfunction-associated fatty liver disease (NAFLD/MAFLD) and non-alcoholic steatohepatitis (NASH), which represents the hepatic component of MS. Furthermore, about 20-40% of KT recipients present early graft inflammation, including subclinical inflammation.

Stable isotope tempestology of tropical cyclones across the North Atlantic and Eastern Pacific Ocean basins.

Tropical cyclones (TCs) are one of the major natural hazards to island and coastal communities and ecosystems. However, isotopic compositions of TC-derived precipitation (P) in surface water (SW) and groundwater (GW) reservoirs are still lacking. We tested the three main assumptions of the isotope storm "spike" hypothesis (sudden spikes in isotopic ratios).

Associations of smoke-free policies in multi-unit housing with smoking behavior and second-hand smoke exposure: A systematic review.

Background And Aim: Although considerable progress has been made regarding the implementation of smoke-free policies (SFPs), many people continue to be exposed to second-hand smoke (SHS) in the home environment. The aim of this study was to conduct a systematic review on the association of SFPs in multi-unit housing (MUH) with smoking behavior and SHS exposure.

Methods: In August 2022, we searched five online databases: PubMed, Embase, Web of Science, PsycINFO and CENTRAL.
