INTRODUCTION: We conducted a phase 1 clinical trial in nine patients with mild-to-moderate Alzheimer's disease to evaluate the safety and dose-limiting toxicity of stereotactic brain injection of human umbilical cord blood-derived mesenchymal stem cells (hUCB-MSCs). METHODS: cells/60 μL, respectively, into the bilateral hippocampi and right precuneus. RESULTS: No patient showed serious adverse events including fever during the 24-month follow-up period. During the 12-week follow-up period, the m

BACKGROUNDS: Alzheimer's disease is the most common cause of dementia, and currently, there is no disease-modifying treatment. Favorable functional outcomes and reduction of amyloid levels were observed following transplantation of mesenchymal stem cells (MSCs) in animal studies. OBJECTIVES: We conducted a phase I clinical trial in nine patients with mild-to-moderate Alzheimer's disease dementia to evaluate the safety and dose-limiting toxicity of three repeated intracerebroventricular injection

BACKGROUND: Immature platelet fraction (IPF, %) is a measure of reticulated platelets (RPs), which represents the state of thrombopoiesis. The IPF is obtained from an automated hematology analyzer as one of the platelet parameters. This study was performed to establish reference intervals of IPF and its cut-off values for the differential diagnosis of thrombocytopenia. METHODS: Blood samples from 2,039 healthy individuals (1,161 males, 878 females) were obtained to establish reference intervals.

This study compared the effects of di(n-butyl) phthalate (DBP) on the oxidative damage and antioxidant enzymes activity in testes of hyperthyroid rats. Hyperthyroidism was induced in pubertal male rats by intraperitoneal injection of triiodothyronine (T3, 10 microg/kg body weight) for 30 days. An oral dose of DBP (750 mg/kg) was administered simultaneously to normal or hyperthyroid (T3) rats over a 30-day period. No changes in body weight were observed in the hyperthyroid groups (T3, T3 + DBP) c

OBJECTIVES: This study explored whether religiosity/spirituality has a protective role against negative caregiving outcomes, in a large multicenter nationwide sample of caregivers of patients with dementia in South Korea. Additionally, this study was the first to examine whether religiosity/spirituality could affect caregiving outcomes according to the various religious affiliations of caregivers. METHODS: The study was conducted on a sample of 476 caregivers of patients with dementia participat

Tuberculosis is still a serious communicable disease in Korea. The prevalence of tuberculosis had been rapidly decreased in past by the country widely expanded national control program, improvement of nutrition and development of medical services. However, decline of tuberculosis is recently stagnated because of increase of aged population and the prevalence of other chronic disease such as diabetes. The registry number of new tuberculosis patients was 36,305 and 2,365 cases were died of tubercu

Autosomal dominant non-syndromic hearing loss (AD-NSHL) is one of the most common genetic diseases in human and is well-known for the considerable genetic heterogeneity. In this study, we utilized whole exome sequencing (WES) and linkage analysis for direct genetic diagnosis in AD-NSHL. The Korean family had typical AD-NSHL running over 6 generations. Linkage analysis was performed by using genome-wide single nucleotide polymorphism (SNP) chip and pinpointed a genomic region on 5q31 with a signi

Rearrangements of the MLL gene on chromosome 11, band q23, are one of the most common genetic changes in acute leukemia. Reciprocal translocation is the most common form of MLL rearrangement, and the partner genes in MLL translocation are notably diverse. Involvement of the SEPTIN6 gene on Xq24 in MLL rearrangements occurs very rarely, with only six cases having been documented in the literature. Of note, the MLL/SEPTIN6 rearrangements in these cases were cryptic or complex, and it was shown tha

Diamond-Blackfan anemia (DBA) is an inherited bone marrow failure syndrome characterized by pure red cell aplasia, various congenital anomalies, and cancer predisposition. We report a novel mutation in the RPS17 gene in a Korean patient with DBA. The mutation occurred in the translation initiation codon, changing Atg to Gtg (c.1A>G), thus disrupting the natural start of the RPS17 protein biosynthesis. This is the third case of DBA from a RPS17 mutation in the literature and is the second case of

Iron-refractory iron deficiency anemia (IRIDA) is a rare hereditary form of IDA with autosomal recessive inheritance. IRIDA is characterized by hypochromic microcytic anemia unresponsive to oral iron treatment, low transferrin saturation, and a high level of iron-regulated hormone hepcidin. The genetic background of IRIDA is mutations in the TMPRSS6 gene encoding matriptase-2 (TMPRSS6) that prevent inactivation of hemojuvelin, an activator of hepcidin transcription. We herein report a Korean fem

Translocations involving the MLL gene on the chromosome 11 (11q23) are frequently observed in acute leukaemia. The detection of this genetic change has a unique significance as a result of its implication of poor prognosis. To reveal the utility of fluorescence in situ hybridization (FISH) in detecting the MLL translocation, we analysed 289 consecutive Korean patients (children and adults) with acute leukaemias using both conventional cytogenetic analysis (CC) and FISH, placing an emphasis on th
