Objectives: The purpose of the study was to investigate the effect of calcium concentration in saliva on dental caries activity after consuming calcium. Methods: A total of 59 adult women aged 20 to 40 years were surveyed for calcium intake. The daily average calcium intake was analyzed through dietary records of the subjects. The subjects were divided into two groups based on daily average calcium intake. Salivary pH and concentrations of minerals in the saliva were obtained from A group and B group. Calcium ($Ca^{2+}$) and magnesium ($Mg^{2+}$) concentrations in saliva were measured by HPLC-Ion chromatography using 15 mM sulfuric acid. The dental caries activity test was quantified by salivary buffer capacity test and plaque pH test. Results: The mean $Ca^{2+}$ concentrations of A group was $12.75{\mu}g/m$, the mean $Ca^{2+}$ concentrations in the B group was $16.30{\mu}g/mL$ (p<0.05) and respectively, $Mg^{2+}$ concentrations were found to be $0.48{\mu}g/mL$ and $0.51{\mu}g/mL$. Calcium intake and calcium concentration in saliva showed a significant correlation (r=0.380). Conclusions: The mean $Ca^{2+}$ concentrations in saliva was higher in the high calcium intake group. Therefore, calcium intake in saliva was correlated with dental caries.

This retrospective case series assessed the effectiveness of commercially available oral fecal microbiota transplantation (FMT) for treating chronic enteropathies in eight animals, five dogs, and three cats, between 2020 and 2023 at the Seoul National University Veterinary Medical Teaching Hospital. Chronic enteropathies, often resistant to conventional therapies, present a significant challenge in veterinary medicine. To assess oral capsule FMT's effectiveness (Doggybiome^® one capsule daily for dogs and Kittybiome^® one capsule daily for cats) as a universal adjunctive therapy for chronic enteropathies across species not responding to traditional treatments. This retrospective case series applied a uniform evaluation of gastrointestinal symptoms and treatment efficacy, utilizing established scoring systems (Canine Inflammatory Bowel Disease Activity Index [CIBDAI] and Canine Chronic Enteropathy Clinical Activity Index [CCECAI] for dogs, Feline Chronic Enteropathy Activity Index [FCEAI] for cats) before and one month after FMT. This approach ensured consistency in hypothesis testing across the study population. Results revealed significant improvements in clinical indices post-FMT, with notable reductions in the CIBDAI, CCECAI, and FCEAI scores (p < 0.05). Additionally, symptoms such as anorexia, lethargy, diarrhea, vomiting, and weight loss showed marked improvement, with normalization of appetite and activity levels observed in most cases. No adverse effects were reported, indicating the safety and tolerability of this treatment. This study highlights the potential of oral capsule FMT as a viable therapeutic option for dogs and cats with chronic enteropathies unresponsive to conventional treatments, providing a new avenue for clinical management. Further research is warranted to expand these findings and explore the microbiome changes associated with FMT in veterinary patients.

This study was undertaken to evaluate whether peroxisome proliferator-activated-receptor-gamma $(PPAR-{\gamma})$ agonist-rosiglitazone (ROSI) induces postischemic functional recovery in Langendorf heart model. Hearts isolated from normal rats were subjected to 20 min of normoxia or 25 min zero-flow ischemia followed by 50 min reperfusion. In this acute protocol, ROSI $(20\;{\mu}g/ml)$ administered 10 min before ischemia had no effect on hemodynamic cardiac function, but had protective effect on lipid peroxidation in in vitro experiments. In chronic protocol in which ROSI was given by daily gavage (4 mg/kg) for three consecutive days, ROSI could not prevent the hemodynamic alteration on cardiac performance, but has protective effect on the activity of superoxide dismutase (SOD). There was no significant difference in the contents of reduced glutathione (GSH) and catalase activity between ischemia-reperfusion (IR) and ROSI treated IR hearts. Although ROSI had no effect on hemodynamic factor, it had effect on antioxidant activity. Our results indicate that ROSI provides partial beneficial effects by inhibiting lipid peroxidation and/or recovering normal level of SOD activity in the ischemic reperfused heart.

For elderly people, an advanced training machine that uses actuator and can adjust load according to muscle activity is proposed. The proposed machine allows users to have a safe and effective training through exercise close to ordinal motion appears in daily life such as stretching or stooping motion. A muscle activity sensor real-timely monitors the activation level of user's muscle during the exercise and the training load is adjusted based on the measured data. The training load is exerted and continuously controlled by electric/pneumatic actuator.

This study was intended to investigate the effects of nutritional, physical and environmental conditions on the bone status of 102 pre and post menopausal women living in Ulsan area. The results of this study are summarized as follows : when subjects were classified into two groups by bone status, there were significant differences in age, calcium index, serum estrogen and physical activity between two groups. Average daily calcium intake of subjects was 682.9 (149.2)mg, which is almost same as RDA, but 41.1% of the subjects consumed calcium below RDA. Calcium index(p<0.05), serum estrogen(p<0.001), physical activity(p<0.001) of poor bone group were significantly lower than those of good bone group. Although there was not a significant difference between bone status and other influential factors, such as family type, skip meal, alcohol drinking, smoking and BMI, each has been shown to have an effect, if slight, on the bone status.

Effects of quercetin on the specific and non-specific immune responses were studied in vivo. Quercetin at a dose of 2.5, 5, 10, 20 and 40 mg/kg were orally administered to ICR male mice once daily for 28 consecutive days. Cyclophosphamide was injected intraperitoneally to ICR mice with a single dose of 5 mg/kg 2 days before secondary immunization. Mice were sensitized and challenged with sheep red blood cells (S-RBC). Immune responses were evaluated by humoral and cellular immune reponses and non-specific immune response. The results of this study were summarized as followings; 1. Quercetin significantly decreased the body weight, and introduced the atrophy of liver, spleen and thymus gland dose-dependently, but increased the numbers of white blood cell. 2. Querectin significantly depressed the hemagglutination titer, Arthus reaction and hemolytic plaque forming cell. 3. Quercetin significantly depressed the delayed type hypersensitivity and rosette forming cell. 4. Quercetin at a dose of 2.5, 5 and 40 mg/kg significantly depressed phagocytic activity. 5. Quercetin at a dose of 10 and 20 mg/kg significantly increased natural killer cell activity.

Changes in a person's health affect one's lifestyle and work activities. According to the World Health Organization (WHO), abnormal activity is growing faster in people aged 60 or more than any other age group in almost every country. This trend steadily continues and expected to increase further in the near future. Abnormal activity put these people at high risk of expected incidents since most of these people live alone. Human abnormal activity analysis is a challenging, useful and interesting problem among the researchers and its particularly crucial task in life and health care areas. In this paper, we discuss the problem of abnormal activities of old people lives alone at home. We propose Convolutional Neural Network (CNN) based model to detect the abnormal behaviors of elderlies by utilizing six simulated action data from daily life actions.
