Connective tissue growth factor (CTGF) regulates the fusion of osteoclast precursors by inhibiting Bcl6 in periodontitis.

Connective tissue growth factor (CTGF), an extracellular matrix protein with various biological functions, is known to be upregulated in multiple chronic diseases such as liver fibrosis and congestive heart failure, but the mechanism it undertakes to cause alveolar bone loss in periodontitis remains elusive. The present study therefore investigates the pathways involving CTGF in chronic periodontitis. RNA sequencing revealed a notable increase in the expression of CTGF in chronic periodontitis tissues.

Effects of Searing Cooking on Sensory and Physicochemical Properties of Beef Steak.

The purpose of the present study was to evaluate the sensory and instrumental quality of thawed beef steak prepared by searing and oven cooking. Beef purchased in the local market was divided into two groups; one group was cooked in a 180°C oven until the internal temperature reached 60°C, and the other group was oven cooked until 35°C, then cooked in a 250°C pan until the internal temperature reached 60°C. Despite a noticeable change in appearance due to the high temperature of the searing, there was no significant difference in juiciness, water content, and cooking loss between the searing-cooked and the oven-cooked steaks.

Stemness evaluation of mesenchymal stem cells from placentas according to developmental stage: comparison to those from adult bone marrow.

This study was done to evaluate the stemness of human mesenchymal stem cells (hMSCs) derived from placenta according to the development stage and to compare the results to those from adult bone marrow (BM). Based on the source of hMSCs, three groups were defined: group I included term placentas, group II included first-trimester placentas, and group III included adult BM samples. The stemness was evaluated by the proliferation capacity, immunophenotypic expression, mesoderm differentiation, expression of pluripotency markers including telomerase activity.

Treatment of generalized hyperhidrosis with oxybutynin in post-menopausal patients.

Postmenopausal hyperhidrosis is a form of secondary hyperhidrosis, and hormone-replacement therapy is a commonly used therapeutic option. However, some women do not benefit from this treatment, and oral anticholinergics are a logical alternative for reducing generalized sweating in these patients. Twenty-one patients were medicated with 5 or 10 mg of oxybutynin per day.

Human placenta-derived feeders support prolonged undifferentiated propagation of a human embryonic stem cell line, SNUhES3: comparison with human bone marrow-derived feeders.

Co-culture of human embryonic stem (ES) cells on mouse fibroblast feeders is the commonly used method for in vitro expansion of human ES cells in an undifferentiated state. However, it has potential risks of pathogen transmission from animals; thus, human cell-derived feeders have been employed to minimize this problem. In this study, we compared human placenta-derived feeders with bone marrow to demonstrate its effectiveness as feeders for in vitro long-term culture of human ES cells.

Hematopoietic differentiation of embryoid bodies derived from the human embryonic stem cell line SNUhES3 in co-culture with human bone marrow stromal cells.

Human embryonic stem (ES) cells can be induced to differentiate into hematopoietic precursor cells via two methods: the formation of embryoid bodies (EBs) and co-culture with mouse bone marrow (BM) stromal cells. In this study, the above two methods have been combined by co-culture of human ES-cell-derived EBs with human BM stromal cells. The efficacy of this method was compared with that using EB formation alone.
