Prokaryotes constitute the majority of sedimentary biomass, where they cycle organic carbon and regulate organic matter transformation. The microbes inhabiting sediment are diverse, and the factors controlling microbial community composition are not fully understood. Here, we characterized the prokaryotic community using 16S rRNA gene sequencing in 24 stratigraphic layers within a 89 cm (dated to ~1900 years old) sediment core from an anchialine sinkhole in the Bahamas with a stratified water column and anoxic bottom water. The microbial community was dominated by members of the Alphaproteobac...

Anemia in pregnancy is defined as a hemoglobin level of less than 11g/dl, and is commonly due to iron deficiency.

Therefore, in this educational culture, how to achieve a good educational effect is also a topic worthy of discussion. However, whether students really engage in those tutoring programs provided by cram schools has seldom been studied. To address this gap, this study explored how parents’ hovering attitude toward life and coursework influences their children’s engagement in cram s...

Introduction: Since the beginning of the COVID-19 pandemic, many patients with clinically acute presentations have been approached differently. The fear for viral transmission along with the short period of study made patients delay their hospital visits and doctors to reassess the approach of certain acute situations. This study aimed to assess the changes in the management of patients with acute cholecystitis before and during COVID-19. Methods: A systematic review of the literature using PubMed (Medline), Scopus and ScienceDirect databases was performed until 01 September 2021. Two kinds of...
