A STUDY ON THE LONG-TERM MONITORING OF SPORTS ACTIVITIES
INTRODUCTION: Lots of studies to analyze and classify human movement patterns using various sensors have been carried out (Mathie, 2004; Allen, 2006) because accurate information of body activity is required to provide promotion of health and health plan. Thus this study was conducted to study the classification and monitoring of various sports activities in real-time environment using single waist mounted tri-axial accelerometer
Improved osseointegration of dental titanium implants by TiO2 nanotube arrays with recombinant human bone morphogenetic protein-2: a pilot in vivo study
In-situ fabrication of cobalt-doped SrFe2As2 thin films by using pulsed laser deposition with excimer laser
The remarkably high superconducting transition temperature and upper critical
field of iron(Fe)-based layered superconductors, despite ferromagnetic material
base, open the prospect for superconducting electronics. However, success in
superconducting electronics has been limited because of difficulties in
fabricating high-quality thin films. We report the growth of high-quality
c-axis-oriented cobalt(Co)-doped SrFe2As2 thin films with bulk
superconductivity by using an in-situ pulsed laser deposition technique with a
248-nm-wavelength KrF excimer laser and an arsenic(As)-rich phase target. The
temperature and field dependences of the magnetization showing strong
diamagnetism and transport critical current density with superior Jc-H
performance are reported. These results provide necessary information for
practical applications of Fe-based superconductors.Comment: 8 pages, 3figures. to be published at Appl. Phys. Let
Effect of rutin from tartary buckwheat sprout on serum glucose-lowering in animal model of type 2 diabetes
This study investigates the anti-diabetic effects of rutin from tartary buckwheat sprout in type 2 diabetes mouse model. The rutin content in tartary buckwheat sprout (TBS) is five times higher than that found in common buckwheat sprout (CBS) as evident from high-performance liquid chromatography analysis. Administration of either rutin or TBS ethanolic extract to diabetes mice decreased the serum glucose level significantly. Rutin down-regulated the expression levels of protein-tyrosine phosphatase 1B; negative regulator of insulin pathway, both transcriptionally and translationally in myocyte C2C12 in a dose-dependent manner. In conclusion, rutin can play a critical role in down-regulation of serum glucose level in type 2 diabetes
How Much Do Older Adults Living Alone in Rural South Korea Know About Dementia?
Objectives This study aimed to examine the level of dementia knowledge of older Korean adults living alone in rural areas and to identify related factors. Methods A cross-sectional descriptive design was applied. The participants were 231 older adults living alone who were recruited from 12 of the 13 primary health care posts in the rural area of Chuncheon. Participantsā level of dementia knowledge was assessed using the Dementia Knowledge Scale. Data were analyzed using descriptive statistics, and the t-test, analysis of variance, chi-square test, and Mann-Whitney test were applied. Results Participantsā mean age was 77.3Ā±5.4 years, and women comprised 79.7% of the sample. Over half of the participants (61.9%) had no formal education, and all the participants were enrolled in Medical Aid. The participantsā average percentage of correct answers was 61.6%. The highest rate (94.4%) was for the item āDementia can change oneās personal character.ā The item with the lowest proportion of correct answers was āDementia is not treatableā (23.4%). Dementia knowledge was significantly associated with age, education, health coverage, source of living expenses, and dementia risk. Conclusions Dementia knowledge among Korean rural older adults living alone was relatively low. Participantsā misconceptions about symptoms and treatment could hinder them from seeking early treatment. The results of this study suggest the need for active outreach and health care delivery for rural older adults living alone in South Korea
Immunoglobulin G Subclass Deficiency is the Major Phenotype of Primary Immunodeficiency in a Korean Adult Cohort
Primary immunodeficiency disease (PID) is a rare disorder in adults. Most often, serious forms are detected during infancy or childhood. However, mild forms of PID may not be diagnosed until later in life, and some types of humoral immunodeficiency may occur in adulthood. The purpose of this study was to identify clinical features of PID in Korean adults. A retrospective study was performed on 55 adult patients who were diagnosed as PID between January 1998 and January 2009 at a single tertiary medical center in Korea. IgG subclass deficiency was the most common phenotype (67%, 37/55), followed by total IgG deficiency (20%, 11/55), IgM deficiency (7%, 4/55), common variable immunodeficiency (2%, 1/55), and X-linked agammaglobulinemia (2%, 1/55). IgG3 and IgG4 were the most affected subclasses. Upper and lower respiratory tract infections (76%) were the most frequently observed symptoms, followed by multiple site infection (11%), urinary tract infection, and colitis. Bronchial asthma, rhinitis, and several autoimmune diseases were common associated diseases. IgG and IgG subclass deficiency should be considered in adult patients presenting with recurrent upper and lower respiratory infections, particularly in those with respiratory allergies or autoimmune diseases
Cell typeādependent variation in paracrine potency determines therapeutic efficacy against neonatal hyperoxic lung injury
AbstractBackground aimsThe aim of this study was to determine the optimal cell type for transplantation to protect against neonatal hyperoxic lung injury. To this end, the inĀ vitro and inĀ vivo therapeutic efficacies and paracrine potencies of human umbilical cord bloodāderived mesenchymal stromal cells (HUMs), human adipose tissueāderived mesenchymal stromal cells (HAMs) and human umbilical cord blood mononuclear cells (HMNs) were compared.MethodsHyperoxic injury was induced inĀ vitro in A549 cells by challenge with H2O2. Alternatively, hyperoxic injury was induced in newborn Sprague-Dawley rats inĀ vivo by exposure to hyperoxia (90% oxygen) for 14 days. HUMs, HAMs or HMNs (5Ā Ć 105 cells) were given intratracheally at postnatal dayĀ 5.ResultsHyperoxia-induced increases in inĀ vitro cell death and inĀ vivo impaired alveolarization were significantly attenuated in both the HUM and HAM groups but not in the HMN group. Hyperoxia impaired angiogenesis, increased the cell death and pulmonary macrophages and elevated inflammatory cytokine levels. These effects were significantly decreased in the HUM group but not in the HAM or HMN groups. The levels of human vascular endothelial growth factor and hepatocyte growth factor produced by donor cells were highest in HUM group, followed by HAM group and then HMN group.ConclusionsHUMs exhibited the best therapeutic efficacy and paracrine potency than HAMs or HMNs in protecting against neonatal hyperoxic lung injury. These cell type-dependent variations in therapeutic efficacy might be associated or mediated with the paracrine potency of the transplanted donor cells
