Quorum quenching (QQ) has effectively prevented biofouling in membrane bioreactors (MBRs) employing isolated QQ bacterial strains. However, the influence of QQ on the microbial population still needs to be fully understood. This research aims to analyze the microbial population in MBRs over an extended period (>250 days) under different conditions, such as varying aeration intensities and doses of QQ bacteria, QQ media, and types of feed.

A strictly anaerobic hyperthermophilic archaeon, designated strain IOH2, was isolated from a deep-sea hydrothermal vent (Onnuri vent field) area on the Central Indian Ocean Ridge. Strain IOH2 showed high 16S rRNA gene sequence similarity to MM 739 (99.42 %), DSM 10322 (99.

Spinach has been suggested as a potential rotation crop for increasing crop yield by enhancing beneficial fungal microbes in continuous monocropping. However, no research on the use of spinach as a green manure has been reported. Thus, we tested the effects of spinach and Korean mustard cultivars (green and red mustards) (10 g pot ) as green manure on soil chemical properties, pepper productivity, and soil microbiome of long-year pepper-monocropped soil.

Article Synopsis
  • Downer cows can result from various issues like paralysis, neurological damage, or infections, but those with unknown causes pose challenges due to undetectable bacterial agents.
  • This study compares the bacterial communities in the brain tissues of downer cattle (with unknown etiology) and healthy cattle, finding significant differences in bacterial diversity and specific genera between the two groups.
  • The research also identifies functional gene variations related to important biological processes in the microbiota, suggesting these microbial differences could help identify potential bacterial causes of downer cow syndrome.

Owing to the emergence and improvement of high-throughput technology and the associated reduction in costs, next-generation sequencing (NGS) technology has made large-scale sampling and sequencing possible. With the large volume of data produced, the processing and downstream analysis of data are important for ensuring meaningful results and interpretation. Problems in data analysis may be encountered if researchers have little experience in using programming languages, especially if they are clinicians and beginners in the field.

Type 2 diabetes (T2D) and T2D-associated comorbidities, such as obesity, are serious universally prevalent health issues among post-menopausal women. Menopause is an unavoidable condition characterized by the depletion of estrogen, a gonadotropic hormone responsible for secondary sexual characteristics in women. In addition to sexual dimorphism, estrogen also participates in glucose-lipid homeostasis, and estrogen depletion is associated with insulin resistance in the female body.

  • The dataset includes microbial data from spontaneously fermented Ethiopian honey wine collected from three locations, analyzed using culture-independent amplicon sequencing.
  • The analysis revealed lower diversity and richness in both bacterial and fungal communities across all samples, with samples from Debre Markos showing significant differences in their microbial compositions.
  • This information could aid in improving the fermentation process by transitioning to a directed inoculated fermentation approach.

Ethiopian honey wine, Tej, is spontaneously fermented traditional alcoholic beverage, usually made from honey and "gesho" (Rhamnus prinoides). Till now, limited amount of information is available on the characterization of Tej. Thus, the aim of this paper is to reveal the microbiological diversity and physicochemical properties of Tej samples collected from different areas of Ethiopia.

Photolytic quorum quenching by ultraviolet A (UVA) irradiation is an effective strategy for controlling membrane bioreactor (MBR) biofouling; however, its effects on MBR microbial communities and functional genes have not yet been explored. Here, we report on the effects of the UVA irradiation, which mitigates membrane biofouling, on the microbial community structures, alpha and beta diversities, and functional gene expressions in the MBR mixed liquor and biocake (membrane fouling layer) for the first time. The results show that the microbial communities become less diversified when alternating UVA is applied to the MBRs.

Conceptualization to utilize microbial composition as a prediction tool has been widely applied in human cohorts, yet the potential capacity of soil microbiota as a diagnostic tool to predict plant phenotype remains unknown. Here, we collected 130 soil samples which are 54 healthy controls and 76 ginseng rusty roots (GRRs). Alpha diversities including Shannon, Simpson, Chao1, and phylogenetic diversity were significantly decreased in GRR ( < 0.

The skin microbiome, especially the axillary microbiome, consists of odor-causing bacteria that decompose odorless sweat into malodor compounds, which contributes to the formation of body odor. Plant-derived products are a cheap source of bioactive compounds that are common ingredients in cosmetics. Microbial bioconversion of natural products is an ecofriendly and economical method for production of new or improved biologically active compounds.

  • The Korean endemic slender catfish has not had its complete mitochondrial genome sequenced, despite its importance as a biological resource.
  • The complete mitochondrial genome is 16,524 base pairs long and includes 22 tRNAs, 2 rRNAs, 13 protein-coding genes, and an A+T rich region.
  • The genome has a base composition of 56.1% A+T and 43.9% C+G, indicating a slight A+T bias, and phylogenetic analysis shows it is closely related to another unspecified species.

  • Emerging evidence suggests that the gut microbiome can predict certain cancers or illnesses, but the role of vaginal microbiome in predicting CIN severity is still unclear.
  • In this study, vaginal swab samples from 66 participants were analyzed, revealing no significant microbial diversity difference between CIN 1- and CIN 2+ groups, but identifying a unique dominant type.
  • A random forest model identified 33 bacterial species that could effectively distinguish CIN 2+ from CIN 1- with high accuracy, indicating the potential of vaginal microbiome as a biomarker for CIN severity.

Background: The transoral endoscopic thyroidectomy vestibular approach (TOETVA) has been the subject of increasing interest from several institutions around the world over the last 2 years. Recently, we successfully performed TOETVA in live human patients without CO gas using our newly designed retractable blade.

Methods: We reviewed the medical records of 15 consecutive patients who underwent gasless TOETVA using a self-retaining retractor.

Background: : Transoral thyroid surgery represented by the da Vinci system is attracted attention and performed by several institutions. However, the current available da Vinci system still has some limitations to be improved for transoral thyroid surgery including high cost of equipment and expendables, larger diameter scope and instruments and no tactile sensation. It triggered us interest in more easily available robotic scope holder.

[Purpose] The purpose of this study was to evaluate the effect of physical therapy on elasticity of muscles quantitatively by using sonoelastography equipment in infrared and ultrasound treatment commonly used in hospital physical therapy rooms. [Participants and Methods] We also investigated correlations among various variables such as height, weight, BMI (Body Mass Index), body fat mass, muscle mass, and basal metabolic rate. From July 30th 2017 to August 30th, 2017, muscular elasticity ratio was measured in 10 males in their 20s by comparing muscles of the upper and lower extremities before and after ultrasound and infrared therapy.
