The Relationship between Metabolic Syndrome and Smoking and Alcohol Experiences in Adolescents from Low-Income Households.

Metabolic syndrome (MetS) in children and adolescents is increasing globally and the age of onset is gradually decreasing. MetS is associated with serious health problems and presents an early risk for adult morbidity and mortality. From 2014-2019, we investigated the relationship between MetS and health behaviors such as smoking, alcohol consumption, and nutrition education in Korean adolescents (boys: 1235, girls: 1087, age: 13-18 years) based on household income; the relationship with hand grip strength was also evaluated.

Comparison of Health Awareness in South Korean Middle School Students According to Type of Online Physical Education Classes during the COVID-19 Pandemic.

Coronavirus disease 2019 popularized online classes to prevent educational deficits affected by the pandemic. This study aimed to assess the differences in the importance and performance of health awareness in Korean middle school students according to the types of online physical education classes they attended during the coronavirus disease 2019 pandemic. Overall, 583 participants were selected using a convenience sampling method; the data were obtained through an online survey using Google forms.

Role of physical exercise in modulating the insulin-like growth factor system for improving breast cancer outcomes: A meta-analysis.

Background: Physical activity prevents cancer and improves cancer outcomes. Insulin-like growth factor (IGF) signaling plays a significant role in cancer development and progression. However, there are heterogeneous results regarding physical activity and its effect on the IGF system.

Transcranial Direct Current Stimulation of motor cortex enhances running performance.

Transcranial direct current stimulation (tDCS) is a technique used to modulate neuronal excitability through non-invasive brain stimulation that can enhance exercise performance. We hypothesize that tDCS would improve submaximal running time to exhaustion (TTE) and delay the increase in the rating of perceived exertion (RPE) over time. We also hypothesize that tDCS would not lead to difference in cardiorespiratory responses.

A case of bilateral revision total knee arthroplasty using distal femoral allograft-prosthesis composite and femoral head allografting at the tibial site with a varus-valgus constrained prosthesis: ten-year follow up.

Background: We report the successful use of allograft-prosthesis composite (APC) and structural femoral head allografting in the bilateral reconstruction of large femoral and tibial uncontained defects during revision total knee arthroplasty (RTKA).

Case Presentation: A 67-year-old female with degenerative arthritis underwent bilateral total knee arthroplasty (TKA) using the Press Fit Condylar (PFC) modular knee system at our clinic in March, 1996. At 8 years postoperatively, the patient presented with painful, bilateral varus knees, with swelling, limited passive range of motion (ROM), and severe instability.

Risedronate directly inhibits osteoclast differentiation and inflammatory bone loss.

Risedronate, a nitrogen-containing bisphosphonate, is widely used in the clinical field for the treatment of osteoporosis. Risedronate is known to exert its effects through binding to hydroxyapatite in bone tissue, inhibiting osteoclastic activity, and inducing apoptosis of osteoclasts. The purpose of this study was to determine the effects of risedronate on osteoclast differentiation in vitro and on an inflammatory bone loss model in vivo.

Ammonium glycyrrhizinate protects gastric epithelial cells from hydrogen peroxide-induced cell death.

Glycyrrhiza uralensis has a potential for preventing or ameliorating gastric mucosal ulceration. To understand the molecular mechanism about the medicinal effect of G. uralensis, we isolated four single compounds from G.

Active Video Games and Energy Expenditure in Overweight Children.

The prevalence of overweight in children has increased significantly in recent years. Frequent television viewing and the playing of video games have often been linked to the high prevalence of overweight. The purpose of this study was to determine if overweight children, given access to active video games, will play them at an intensity that will significantly increase energy expenditure.
