Aging-Induced Changes in and Their Effects on Skin Elasticity and Wrinkle Formation.

Skin aging involves biomechanical changes like decreased elasticity, increased wrinkle formation, and altered barrier function. The skin microbiome significantly impacts this process. Here, we investigated the effects of decreased abundance and increase in other skin microorganisms on skin biomechanical properties in 60 healthy Koreans from Seoul, divided into younger (20-29 years) and older (60-75 years) groups.

Effect of extracorporeal shock wave therapy on the microbial community in burn scars: retrospective case-control study.

Background: The effectiveness of extracorporeal shock wave therapy (ESWT) has been demonstrated in various medical fields, including burn medicine. It promotes wound healing, improves blood flow, and modulates the inflammatory responses. The recovery speed and outcomes of skin diseases are influenced by the skin microbiome; however, studies examining the effects of specific treatments on the skin microbiome are lacking.

Anti-Fibrosis Effect of and Formula in Human Pulmonary Fibroblasts.

Meyer and Thunb. are well established in traditional medicine and are known for their therapeutic properties in managing a range of ailments such as diabetes, asthma, and cancer. Although and can alleviate pulmonary fibrosis (PF), the anti-fibrosis effect on PF by the combination of two herbal medicines remains unexplored.

Effects of Factors Influencing Scar Formation on the Scar Microbiome in Patients with Burns.

Skin microbiome dysbiosis has deleterious effects, and the factors influencing burn scar formation, which affects the scar microbiome composition, are unknown. Therefore, we investigated the effects of various factors influencing scar formation on the scar microbiome composition in patients with burns. We collected samples from the burn scar center and margin of 40 patients with burns, subgrouped by factors influencing scar formation.

Does quorum quenching matter to microbial community dynamics in long-term membrane bioreactor operation?

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.

Sex differences in the skin microbiome of burn scars.

Sex differences are observed in various spectrums of skin diseases, and there are differences in wound healing rate. Herein, sex differences were identified for the newly healed skin microbiome of burn patients. Fifty-two skin samples (26 normal skin, 26 burn scars) were collected from 26 burn patients (12 male, 14 female) and microbiota analysis was performed.

Exploration of Potential Gut Microbiota-Derived Biomarkers to Predict the Success of Fecal Microbiota Transplantation in Ulcerative Colitis: A Prospective Cohort in Korea.

Background/aims: Although fecal microbiota transplantation (FMT) has been proven as one of the promising treatments for patients with ulcerative colitis (UC), potential prognostic markers regarding the clinical outcomes of FMT remain elusive.

Methods: We collected fecal samples of 10 participants undergoing FMT to treat UC and those from the corresponding donors. We categorized them into two groups: responders and nonresponders.

Effect of a bioconverted product of Lotus corniculatus seed on the axillary microbiome and body odor.

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.

Quorum Sensing System Affects the Plant Growth Promotion Traits of GS2.

Quorum sensing (QS) enables bacteria to organize gene expression programs, thereby coordinating collective behaviors. It involves the production, release, and population-wide detection of extracellular signaling molecules. The cellular processes regulated by QS in bacteria are diverse and may be used in mutualistic coordination or in response to changing environmental conditions.

Ocean acidification alters bacterial communities on marine plastic debris.

The increasing quantity of plastic waste in the ocean is providing a growing and more widespread novel habitat for microbes. Plastics have taxonomically distinct microbial communities (termed the 'Plastisphere') and can raft these unique communities over great distances. In order to understand the Plastisphere properly it will be important to work out how major ocean changes (such as warming, acidification and deoxygenation) are shaping microbial communities on waste plastics in marine environments.

Modulation of Gut Microbiota in Korean Navy Trainees following a Healthy Lifestyle Change.

Environmental factors can influence the composition of gut microbiota, but understanding the combined effect of lifestyle factors on adult gut microbiota is limited. Here, we investigated whether changes in the modifiable lifestyle factors, such as cigarette smoking, alcohol consumption, sleep duration, physical exercise, and body mass index affected the gut microbiota of Korean navy trainees. The navy trainees were instructed to stop smoking and alcohol consumption and follow a sleep schedule and physical exercise regime for eight weeks.

In Situ Profiling of the Three Dominant Phyla Within the Human Gut Using TaqMan PCR for Pre-Hospital Diagnosis of Gut Dysbiosis.

A microbial imbalance called dysbiosis leads to inflammatory bowel disease (IBD), which can include ulcerative colitis (UC). Fecal microbiota transplantation (FMT), a novel therapy, has recently been successful in treating gut dysbiosis in UC patients. For the FMT technique to be successful, the gut microbiota of both the healthy donors and UC patients must be characterized.

Genome sequencing to develop Paenibacillus donghaensis strain JH8 (KCTC 13049=LMG 23780) as a microbial fertilizer and correlation to its plant growth-promoting phenotype.

Paenibacillus donghaensis JH8 (KCTC 13049=LMG 23780) is a Gram-positive, mesophilic, endospore-forming bacterium isolated from East Sea sediment at depth of 500m in Korea. The strain exhibited plant cell wall hydrolytic and plant growth promoting abilities. The complete genome of P.

The first complete mitochondrial genome sequence of the leucosiid crab (Arthropoda, Decapoda, Leucosiidae).
