Machine learning models for predicting indoor airborne fungal concentrations in public facilities utilizing environmental variables.

Airborne fungi are major contributors to substandard indoor air quality, with potential implications for public health, especially in public facilities. The risk of chronic exposure can be significantly reduced by accurately predicting airborne fungal concentrations. To manage indoor air quality, we developed machine learning (ML) models that predict airborne fungal concentrations in public facilities by utilizing environmental variables, such as facility type, floor, month, air temperature, relative humidity, coarse particulate matter (PM), and 2-day accumulated precipitation.

Development of analytical methods for the determination of 3-hydroxy fatty acids and muramic acid as bacterial markers in airborne particles and settled dust.

Inhalation of airborne bacteria in indoor environments is known to be associated with respiratory diseases. Analytical methods for the determination of 3-hydroxy fatty acids (3-OHFAs) and muramic acid (MA) as chemical markers of gram-negative and gram-positive bacteria, respectively, were developed for airborne particle and dust samples in this study. 3-OHFAs as markers of endotoxin were released and esterified during the hydrolysis process under methanolic acid conditions, and their hydrolysates, i.

Airborne fungal and bacterial microbiome in classrooms of elementary schools during the COVID-19 pandemic period: Effects of school disinfection and other environmental factors.

The aim of the study was to examine the effects of environmental factors including disinfection on airborne microbiome during the coronavirus disease 2019 pandemic, we evaluated indoor and outdoor air collected from 19 classrooms regularly disinfected. Extracted bacterial and fungal DNA samples were sequenced using the Illumina MiSeq™ platform. Using bacterial DNA copy number concentrations from qPCR analysis, multiple linear regressions including environmental factors as predictors were performed.

Anti-colitic effects of the modified Bojanggunbi-tang on dextran sulfate sodium-induced mouse colitis model.

Bojanggunbi-tang (BGT) is a well-known and widely used herbal prescription in Korea for colon diseases, with well-documented pharmacological effects on the digestive system. The current study aimed to develop a new simple and effective prescription using the original prescription. mBGT, a modified BGT, was developed by mixing the extracts of Lonicera japonica Thunb.

Clinical characteristics and pathogens in percutaneous endoscopic gastrostomy site infection in patients with head and neck cancer: A 16-year retrospective study.

Objectives: Wound infection is the most common complication associated with percutaneous endoscopic gastrostomy (PEG) placement, with an incidence between 4% and 30%. In this study, we compared the characteristics of PEG site infection between the head and neck cancer (HNC) group and the non-HNC group.

Methods: This study was conducted at Kangdong Sacred Heart Hospital at the Ilsong Head and Neck Cancer Center.

Investigation of bacterial and fungal communities in indoor and outdoor air of elementary school classrooms by 16S rRNA gene and ITS region sequencing.

The advent of high-throughput sequencing methods allowed researchers to fully characterize microbial community in environmental samples, which is crucial to better understand their health effects upon exposures. In our study, we investigated bacterial and fungal community in indoor and outdoor air of nine classrooms in three elementary schools in Seoul, Korea. The extracted bacterial 16S rRNA gene and fungal ITS regions were sequenced, and their taxa were identified.

Agastache rugosa ethanol extract suppresses bone loss via induction of osteoblast differentiation with alteration of gut microbiota.

Purpose: Osteoporosis is a metabolic skeletal disease characterized by bone loss and an increased risk of fractures. This study aimed to investigate the therapeutic effect of Agastache rugosa on postmenopausal osteoporosis and elucidate its mechanisms in modulating the bone status.

Methods And Results: In the osteoblast differentiation process with MC3T3-E1 pre-osteoblasts, ethanol extract of Agastache rugosa (EEAR) and its compounds increased the expression of the proteins and genes of the osteoblast differentiation-related markers such as Runt-related transcription factor 2 (RUNX2) and β-catenin along with the elevation of calcium deposits.
