Developing a Multi-Directional Lower-Limb Training System Toward Aging in Place Rehabilitation: A Preliminary Feasibility Study on Healthy Individuals.

Not only improving muscle strength but also improving muscle power and neuromuscular control are important factors in improving lower limb function. In this study, a multi-directional lower-limb training system for aging -in-place rehabilitation was developed. The training system offers four distinct modes: muscle power training, pivoting neuromuscular training, muscle strength training using eccentric contractions, and proprioception training with evaluation.

sp. nov. and sp. nov., two bacteria isolated from marine sediment in the East China Sea.

Two Gram-stain-negative, curved-rod-shaped, non-motile and aerobic bacteria W6 and I13 were isolated from marine sediment samples collected from Meishan Island located in the East China Sea. Catalase and oxidase activities and hydrolysis of Tween 40, 60 and 80 were positive for both strains, while nitrate reduction, indole production, methyl red reaction and HS production were negative. Phylogenetic analyses based on 16S rRNA and genome sequences revealed that strains W6 and I13 formed distinct phylogenetic lineages within the genera and , respectively.

Adiponectin Prevents Skin Inflammation in Rosacea by Suppressing S6 Phosphorylation in Keratinocytes.

Numerous recent evidence highlights epidemiological connections between rosacea and metabolic disorders. However, the precise path through which metabolic factors impact rosacea risk is still unclear. Therefore, this study aims to investigate the role of adiponectin, a crucial adipokine that regulates metabolic homeostasis, in the pathogenesis of rosacea.

Functionally similar genes exhibit comparable/similar time-course expression kinetics in the UV-induced photoaged mouse model.

Skin photoaging induced by ultraviolet (UV) irradiation contributes to the formation of thick and coarse wrinkles. Humans are exposed to UV light throughout their lives. Therefore, it is crucial to determine the time-sequential effects of UV on the skin.

sp. nov., a facultative anaerobic bacterium belonging to the family isolated from marine sediment in the East China Sea.

A facultative anaerobic, Gram-strain-negative, rod-shaped bacterium (strain NBU2970) was isolated by using modified ichip cultivation from a marine sediment sample collected from Meishan Island in the East China Sea. Strain NBU2970 grew optimally at 37 °C, with a NaCl concentration of 2.0 % (w/v) and at pH 7.

Microbial Interaction is Among the Key Factors for Isolation of Previous Uncultured Microbes.

Pure cultivation of microbes is still limited by the challenges of microbial uncultivability, with most microbial strains unable to be cultivated under standard laboratory conditions. The experience accumulated from advanced techniques such as in situ cultivation has identified that microbial interactions exist in natural habitats but are absent in laboratory cultures. These microbial interactions are likely one of the key factors in isolating previously uncultured microbes.

Method: This is a randomized controlled trial for patients with type 2 diabetes (glycated hemoglobin ≥ 6.5%), diagnosed by a specialist.

Virtual Reality Exercise Program Effects on Body Mass Index, Depression, Exercise Fun and Exercise Immersion in Overweight Middle-Aged Women: A Randomized Controlled Trial.

Background: This study explored the effects of a virtual reality exercise program on overweight middle-aged women. Methods: This randomized controlled trial included women 40−65 years of age with a body mass index (BMI) of 23 kg/m2 or more living in Daejeon City. The virtual reality environment was set up by attaching an IoT sensor to an indoor bicycle and linking it with a smartphone, enabling exercise in an immersive virtual reality through a head-mounted display.

Construction of full-length infectious cDNA clones of two Korean isolates of turnip mosaic virus breaking resistance in Brassica napus.

In this work, two new turnip mosaic virus (TuMV) strains (Canola-12 and Canola-14) overcoming resistance in canola (Brassica napus) were isolated from a B. napus sample that showed typical TuMV-like symptoms and was collected in the city of Gimcheon, South Korea, in 2020. The complete genome sequence was determined and an infectious clone was made for each isolate.

Reassortment of Infectious Clones of Radish Mosaic Virus Shows that Systemic Necrosis in Is Determined by RNA1.

Three infectious clones of radish mosaic virus (RaMV) were generated from isolates collected in mainland Korea (RaMV-Gg) and Jeju Island (RaMV-Aa and RaMV-Bb). These isolates differed in sequences and pathogenicity. Examination of the wild-type isolates and reassortants between the genomic RNA1 and RNA2 of these three isolates revealed that severe symptoms were associated with RNA1 of isolates Aa or Gg causing systemic necrosis in , or with RNA1 of isolate Bb for induction of veinal necrosis and severe mosaic symptoms in radish.

Aged skeletal stem cells generate an inflammatory degenerative niche.

Loss of skeletal integrity during ageing and disease is associated with an imbalance in the opposing actions of osteoblasts and osteoclasts. Here we show that intrinsic ageing of skeletal stem cells (SSCs) in mice alters signalling in the bone marrow niche and skews the differentiation of bone and blood lineages, leading to fragile bones that regenerate poorly. Functionally, aged SSCs have a decreased bone- and cartilage-forming potential but produce more stromal lineages that express high levels of pro-inflammatory and pro-resorptive cytokines.

Effect of citric acid and heat treatment on the content of less-polar ginsenosides in flower buds of .

Ginseng flower bud (GFB), as an inexpensive part of , attracted significant attention as a beneficial functional food with medicinal potentials due to its high content of ginsenosides. A few studies focused on the utilization of heat treatment and citric acid treatment to process ginseng flowers, converting its polar ginsenosides into rare ginsenosides to improve its biological activities. Thus, in this study, we compared the changes of ginsenosides in GFB after citric acid and heat treatment by HPLC method.

On Training Neural Network Decoders of Rate Compatible Polar Codes via Transfer Learning.

Neural network decoders (NNDs) for rate-compatible polar codes are studied in this paper. We consider a family of rate-compatible polar codes which are constructed from a single polar coding sequence as defined by 5G new radios. We propose a transfer learning technique for training multiple NNDs of the rate-compatible polar codes utilizing their inclusion property.

Full-Length Infectious Clones of Two New Isolates of Tomato Mosaic Virus Induce Distinct Symptoms Associated with Two Differential Amino Acid Residues in 128-kDa Protein.

In 2017, two new tomato mosaic virus (ToMV) isolates were collected from greenhouses in Buyeo, Chungcheongnam-do, South Korea. Full-length cDNAs of the new ToMV isolates were cloned into dual cauliflower mosaic virus 35S and T7 promoter-driven vectors, sequenced and their pathogenicities investigated. The nucleotide sequences of isolates GW1 (MH507165) and GW2 (MH507166) were 99% identical, resulting in only two amino acid differences in nonconserved region II and the helicase domain, Ile668Thr and Val834Ile.

Five Newly Collected Turnip Mosaic Virus (TuMV) Isolates from Jeju Island, Korea are Closely Related to Previously Reported Korean TuMV Isolates but Show Distinctive Symptom Development.

For several years, temperatures in the Korean peninsula have gradually increased due to climate change, resulting in a changing environment for growth of crops and vegetables. An associated consequence is that emerging species of insect vector have caused increased viral transmission. In Jeju Island, Korea, occurrences of viral disease have increased.

Enhancement of lipid content and inflammatory cytokine secretion in SZ95 sebocytes by palmitic acid suggests a potential link between free fatty acids and acne aggravation.

A relationship between acne and free fatty acids (FFAs) has been suggested recently. However, the effects of FFAs on sebaceous glands are still largely unknown. At the same time, the role of FFAs during chronic inflammation is well established.
