Authors have emphasized the need for previous care in order to perform reliable bioimpedance acquisition. Despite of this need some authors have reported that intense physical training has little effect on Bioimpedance Analysis (BIA), while other ones have observed significant effects on bioimpedance parameters in the same condition, leading to body composition estimates considered incompatible with human physiology. The aim of this work was to quantify the changes in bioimpedance parameters, as well as in body fluids estimates by BIA, after four hours of intense physical activity with free water replacement in young males. Xitron Hydra 4200 equipment was used to acquire bioimpedance data before and immediately after the physical training. After data acquisition body fluids were estimates from bioimpedance parameters. Height and weight of all subjects were also acquired to the nearest 0.1 cm and 0.1 kg, respectively. Results point that among the bioimpedance parameter, extracellular resistance presented the most coherent behavior, leading to reliable estimates of the extracellular fluid and part of the total body water. Results also show decreases in height and weight of the participants, which were associated to the decrease in body hydration and in intervertebral discs.

The pandemic has shown viral capacity in massive spreading and environmental adaptability for years. It has infected millions of people with several symptoms leading to millions of mortality worldwide. Its fast-spreading capacity, unpredictability prognosis and variants appearance are leading big threats, particularly to the health facilities. Therefore, appropriate health protection equipment, including adequate and safe decontamination procedures, is required to support the facilities in overcoming potential future contaminating pathogens. Unfortunately, only a few studies evaluated the utilization of medical decontamination devices. Rapid and massive manufacturing of decontamination devices without further and adequate post-monitoring may have several side effects. Therefore, careful and continuing consideration and evaluation studies are necessary to maintain the devices’ quality and performance. This study aims to evaluate the ability of UV lights as laboratory devices to impair viral components. Clinical RNA samples were provided by the COVID-19 laboratory examiner as blinded samples without any subject information. SARS-CoV2 RNA (a viral representative RNA material) extract was exposed to 5 different UV lights, with different distances and exposure duration. The exposed RNA was then sequentially used as a cDNA template and DNA amplification. Amplification products were visualized by electrophoresis and densitometry analysis. Visualization and densitometry analysis showed that the UV-LED Nichia NCSU 334 had the most significant disruptive ability among the tested lights. The exposure duration and distance altered the effectiveness of UV light in damaging viral genetic material. UV-LED Nichia NCSU 334 could be suggested as an alternative UV source in a UV light-based disinfection system. This study proposed direct evidence for evaluating decontamination devices to ensure the effectiveness of the decontamination process.

Objectives: To prospectively investigate associations of frailty and other predictor variables with functional recovery and health outcomes in middle-aged and older patients with trauma. Design: Single-center prospective cohort study. Setting: Emergency department of Wan Fang Hospital in Taiwan. Participants: Trauma patients aged 45 and older. Measurements: Frailty was assessed with the Clinical Frailty Scale (CFS). Injury mechanisms, pre-existing diseases, and fracture locations were recorded at baseline. The primary outcome was functional recovery assessed using the Barthel Index (BI). Secondary outcomes were new care needs, unscheduled return visits, and falls 3 months postinjury. Results: A total of 588 participants were included in the final analysis. For every one-point increase in the CFS, the multivariable-adjusted odds ratio (OR, 95% confidence interval [CI]) of failure to retain the preinjury BI was 1.34 (1.16–1.55);associations were consistent across levels of age and injury severities. Significant joint associations of frailty and age with poor functional recovery were observed. CFS was also associated with new care needs (OR for every one-point increase, 1.36, 95% CI, 1.17–1.58), unscheduled return visits (OR 1.26, 95% CI, 1.04–1.51), and falls (OR 1.23, 95% CI, 1.01–1.51). Other variables associated with failure to retain preinjury BI included road traffic accident and presence of hip fracture. Conclusion: Frailty was significantly associated with poor functional and health outcomes regardless of injury severity in middle-aged and older patients with trauma. Injury mechanisms and fracture locations were also significant predictors of functional recovery postinjury. © 2023 American Association for Geriatric Psychiatry

BACKGROUND:The progressive deterioration of tissue-tissue crosstalk with aging causes a striking impairment of tissue homeostasis and functionality, particularly in the musculoskeletal system. Rejuvenation of the systemic and local milieu via interventions such as heterochronic parabiosis and exercise has been reported to improve musculoskeletal homeostasis in aged organisms. We have shown that Ginkgolide B (GB), a small molecule from Ginkgo biloba, improves bone homeostasis in aged mice by restoring local and systemic communication, implying a potential for maintaining skeletal muscle homeostasis and enhancing regeneration. In this study, we investigated the therapeutic efficacy of GB on skeletal muscle regeneration in aged mice. METHODS:Muscle injury models were established by barium chloride induction into the hind limb of 20-month-old mice (aged mice) and into C2C12-derived myotubes. Therapeutic efficacy of daily administrated GB (12 mg/kg body weight) and osteocalcin (50 μg/kg body weight) on muscle regeneration was assessed by histochemical staining, gene expression, flow cytometry, ex vivo muscle function test and rotarod test. RNA sequencing was used to explore the mechanism of GB on muscle regeneration, with subsequent in vitro and in vivo experiments validating these findings. RESULTS:GB administration in aged mice improved muscle regeneration (muscle mass, P = 0.0374; myofiber number/field, P = 0.0001; centre nucleus, embryonic myosin heavy chain-positive myofiber area, P = 0.0144), facilitated the recovery of muscle contractile properties (tetanic force, P = 0.0002; twitch force, P = 0.0005) and exercise performance (rotarod performance, P = 0.002), and reduced muscular fibrosis (collagen deposition, P < 0.0001) and inflammation (macrophage infiltration, P = 0.03). GB reversed the aging-related decrease in the expression of osteocalcin (P < 0.0001), an osteoblast-specific hormone, to promote muscle regeneration. Exogenous osteocalcin supplementation was

Bacterial cellulose (BC) is a biodegradable nanoscale film produced by microorganisms, which possesses great mechanical properties and biocompatibility. In this study, we produced foaming BC (FBC) utilizing foam medium with different concentrations of agar. In addition, carvacrol was loaded into the agar/FBC to establish active packaging material. Evaluation by characterization tests indicated that agar/FBC provided lower crystallinity (59.8%∼71.4%) and a high swelling ability (94.7%∼97.9%) compared to BC (92.2% and 96.1%). The 1.5% agar/FBC with carvacrol group exhibited the significantly highest antimicrobial properties against Escherichia coli and Staphylococcus aureus. Moreover, release measurements showed that greater agar addition contributed to higher protein and carvacrol release extents out of the film. Finally, a sea bass packaging test indicated that carvacrol with 1.5% agar/FBC presented a higher antimicrobial ability against Shewanella putrefaciens, great inhibition of lipid oxidation (67.5%), and a slower spoilage degree (49.8%) which suggested that agar/FBC with carvacrol has potential for active food packaging. © 2024 Elsevier Ltd

Psoriasis classification requires the accurate identification of the lesional types for the early and effective diagnosis and it is worth interesting that the normal and psoriasis cell tissues exhibit different gene expression. Therefore, gene expression data is an effective source for psoriasis classification and there is a challenge regarding the selection of suitable gene signatures for its purpose. In this present study, the gene expression-based microarray data were used and 35 expression features linked with psoriasis were utilized to feed into our machine learning model. Overall, the performance of our model based on 35 mentioned-above features surpassed that of other state-of-the-art classifiers with an average accuracy of 98.3%, recall of 98.6%, and precision of 98% in 5-fold cross-validation tests. We also validate our model on two different sets of psoriasis and the performance results are significant. These results have suggested that our 35 expression signatures have been identified as key features for classifying samples between lesion and non-lesion. More specifically, the expression levels of few genes i.e., FABP5 , TGM1 , or BCAR3 are discovered as newly potential biomarkers for psoriasis classification and treatment with high confidence. This study, therefore, could shed light on developing the prediction models for psoriasis classification and treatment using gene expression profiles.

Cordyceps militaris (C. militaris) is a unique medicinal fungus of the genus Cordyceps. It has high economic value due to various biological functions from the extracellular polysaccharides (EPSs) it produces. The aim of this study was to establish a mycelium-immobilization system for EPS production in a bubble column system. First, EPS production was optimized by 90.2% (from 0.72 to 1.37 g/L) using response surface methodology under an alginate-immobilized mycelium system with 6 days of cultivation. The highest EPS production was obtained (5.3 g/L) in a flask system through elongation to 15 days of cultivation. EPS production subsequently further increased to 10.42 g/L utilizing a bubble column reactor. Furthermore, the system can be reused for at least three rounds. In the EPS characteristics analysis, the produced EPSs were mainly composed of glucose and galactose. They presented strong antibacterial activity against Staphylococcus aureus. In terms of antioxidant activity, respective the EPS concentration that caused 50% scavenging of DPPH and ABTS free radicals values (IC50) were 4.65 and 7.92 mg/mL. In summary, these findings should be helpful for establishing a suitable industrial fermentation system for C. militaris and can be studied in the food and medical industries in future work. © 2024 The Authors
