Effects of foam roller-based combined exercise on functional fitness, balance, and gait in older women.

This study aimed to investigate the effects of a foam roller-based combined exercise program on functional fitness, balance ability, and gait in women aged 65 years and older. Using a 2×2 mixed design, the study compared variables measured before and after a 6-week foam roller-based combined exercise program. A total of 32 old women were randomly assigned to either the foam roller-based exercise group or the control group.

Recurrence-free survival after hepatectomy using propofol-based total intravenous anaesthesia and sevoflurane-based inhalational anaesthesia: a randomised controlled study.

Background: While evidence from preclinical and observational cohort studies have suggested potential disparities in tumour behaviour associated with the choice of intra-operative anaesthetics, clinical evidence of tumour recurrence and metastasis remains inconclusive. We aimed to compare the impact of intra-operative anaesthesia on oncologic outcomes following hepatectomy for hepatocellular carcinoma.

Methods: Adult patients scheduled for elective hepatectomy for hepatocellular carcinoma were assigned randomly (1:1) to either propofol-based total intravenous anaesthesia or sevoflurane-based inhalational anaesthesia.

The risk factors and outcomes associated with persistent bacteremia are not well-defined. This retrospective cohort study analyzed 214 cases of bacteremia diagnosed between 2005 and 2022 at two university hospitals, focusing on the clinical and microbiologic characteristics and outcomes of persistent bacteremia. Persistent bacteremia, defined as the detection of for ≥5 days after the initial blood culture, occurred in 25.

Sodium Phenylbutyrate Attenuates Cisplatin-Induced Acute Kidney Injury Through Inhibition of Pyruvate Dehydrogenase Kinase 4.

Cisplatin nephrotoxicity is a significant clinical issue, and currently, no approved drug exists to prevent cisplatin-induced acute kidney injury (AKI). This study investigated whether sodium phenylbutyrate (4-PBA), a chemical chaperone, can prevent cisplatin-induced AKI. Six consecutive days of intraperitoneal injections of 4-PBA were administered in a murine model before and after the cisplatin challenge.

Influence of orthodontic bracket block-out materials on superimposition errors when substituting scanned dental imaging data onto computed tomography images.

Purpose: The study was performed to examine the error associated with image superimposition when computed tomography (CT) images of the dental region are substituted with dental scan data, according to the block-out material used in dental impressions.

Materials And Methods: A typodont model was created by bonding orthodontic brackets to teeth on plaster dental stones using melted dental base-plate wax. In the experiment, 2 groups were compared: one using wax and the other using putty as the block-out material to prevent tearing of the impression material during the acquisition of dental impressions.

Combined Autologous Breast Reconstruction and Gynecologic Procedures: Does Timing Affect Clinical and Patient-Reported Outcomes?

Background: Patients with or at risk for breast cancer may opt for risk-reducing gynecologic surgeries, including bilateral salpingo-oophorectomies and/or total abdominal hysterectomy. The timing and safety of combining these procedures with autologous breast reconstruction (ABR) are debated. This study assesses the impact of concurrent ABR and gynecologic surgeries on clinical and patient-reported outcomes.

Chemometrics for estimating the fermentation and quality properties of kimchi based on hyperspectral image analysis.

Kimchi is a traditional Korean dish made from fermenting vegetables. The fermentation process is crucial for enhancing its quality and flavor during storage. Approaches such as hyperspectral imaging (HSI) and chemometrics (PLS, partial least square; SVR, support vector regression) including principal component analysis (PCA), and 2-dimensional correlation spectroscopy (2D-COS) can detect key physical and chemical components and changes in total soluble solids (TSS), pH, titratable acidity (TA), salinity, and lactic acid bacteria (LAB).

Background: To evaluates the tendency of South Korean dentists to over-diagnose clinically healthy teeth in pseudo-patients.

Methods: We conducted a pseudo-patient, cross-sectional study in 196 private dental clinics with 58 pseudo-patients in South Korea between August and December 2018. Trained pseudo-patients with no previous oral diseases, including dental caries, diagnosed by two experienced dentists, were sent to each dental clinic.

Evaluating the capacity of magnetic ionic liquids for separation and concentration of non-enveloped viral particles and free viral genomic RNA.

Magnetic ionic liquids (MILs) have proven effective as capture reagents for foodborne bacterial pathogens; however, there are currently no published studies regarding their use with foodborne, non-enveloped viruses. In this study, a protocol was evaluated for capture and recovery of bacteriophage MS2, a human norovirus surrogate, and purified viral genomic single stranded RNA (ssRNA) from an aqueous suspension using MILs. Transition metal-based MILs showed similar capture and recovery efficiency for both targets.

Deoxynivalenol (DON) is a common mycotoxin observed in cereal grains, and feed contamination poses health risks to pigs. Biological antidotes, such as synbiotics (SYNs), have garnered attention for mitigating DON toxicity. This study aimed to assess the efficacy of SYNs by comparing the blood biochemistry, histology, and gut microbiome of weaned piglets.

-3 Fatty Acids in Seafood Influence the Association Between the Composite Dietary Antioxidant Index and Depression: A Community-Based Prospective Cohort Study.

Accumulating evidence suggests that seafood and its components, such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are associated with mental health. However, little is known regarding whether the status of -3 polyunsaturated fatty acids (PUFAs) modify the effect of dietary antioxidants on depression. The main purpose of study is to investigate longitudinal associations between seafood consumption and depression among 2564 participants aged 40-69 years using data from the Korean Genome and Epidemiology Study.

Multi-Scale Characterization of Conventional and Immediate Dental Implant Systems.

We hypothesized that the different post-implantation healing stages between the conventional and immediate implantations produce different amounts and tissue composition of the peri-implant bone. Thus, the objective of the current study was to examine whether the stability of dental implant systems is associated with characteristics of the interfacial bone area at different post-implanation healing periods. Mandibular molars were extracted from each beagle dog.

In Vitro Modeling of Atherosclerosis Using iPSC-Derived Blood Vessel Organoids.

As modeling of atherosclerosis requires recapitulating complex interactions with vasculature and immune cells, previous in vitro models have limitations due to their insufficient 3D vascular structures. However, induced pluripotent stem cell-derived blood vessel organoids (BVOs) are applicable for modeling vascular diseases, containing multiple cell types, including endothelial and vascular smooth muscle cells self-assembled into a blood vessel structure. Atherosclerotic BVOs with a microenvironment associated with atherogenesis, such as shear stress, low-density lipoprotein, pro-inflammatory cytokine, and monocyte co-culture are successfully developed.

Dynamics of blood Taurine concentration and its correlation with nutritional and physiological status during the fattening period of Japanese black cattle.

Taurine, biosynthesized from methionine or cysteine in the liver, plays a crucial regulatory role in bile acid conjugation, antioxidant effects, and glucose and cholesterol metabolism. This may influence the metabolic changes associated with fat accumulation in beef cattle. However, the physiological role of taurine in this species has not been fully elucidated.

Selective denoising autoencoder for classification of noisy gas mixtures using 2D transition metal dichalcogenides.

Electronic nose (E-nose) technology, which is composed of an array of chemical sensors and pattern recognition, has been widely utilized for the quantitative classification of gas mixtures. However, for the practical use of E-nose in real-industry, advanced algorithms are necessary to handle the noise in sensing data caused by various environmental variables. In order to achieve precise measurements even in real-world environments, it is necessary to denoise and classify noisy sensing data.
