Analysis of the diet, weight-loss behavior, and nutritional knowledge of athletes and coaches in weightclass sports: influence of a coach's nutritional knowledge on athletes.

Background: This study was conducted to investigate the nutritional knowledge of elite athletes undergoing weight loss and to identify differences in weight-loss strategies according to nutritional knowledge.

Methods: The participants included 22 coaches and 88 elite athletes registered under the same affiliation. The survey involved translating the General Nutrition Knowledge Questionnaire (GNKQ), and interviews were used to confirm the diet and weight loss patterns of the athletes.

Analysis of the relationship between body imbalance characteristics and physical ability in air force cadets: physical function and gravity acceleration resistance.

Air Force pilots and some athletes (e.g., in sledding sports) are frequently exposed to high G-forces.

Nutritional knowledge, eating habits, factors affecting muscle damage, and antioxidant enzyme levels of Korean wrestlers.

Purpose: The aim in this study was to investigate the diet and nutritional knowledge of elite Korean wrestlers and verify the differences in their exercise performance , muscle damage indicators, and antioxidant enzyme levels according to wrestler level.

Methods: A 7-day dietary and nutrition knowledge survey was administered to 30 adult male elite wrestlers (national team: n=11; professional team: n=19). The Wingate test was conducted for 60 seconds to analyze muscle damage indicators and antioxidant levels.

Physical strength, body composition, and G-test results of air force cadets based on nutrition knowledge differences.

The Gravitational Acceleration Test (G-test) is a demanding, and sophisticated high-intensity physical activity, greatly influenced by individual body composition and physical strength. This study analyzed the general nutrition knowledge questionnaire (GNKQ) responses of Air Force cadets to identify the relationship between nutrition knowledge, body composition, physical activity, physical strength, and gravity-induced loss of consciousness. Based on the G-test results, 105 fourth-year Air Force cadets were divided into two groups: GP (G-test pass group) and GF (G-test fail group).

Effect of the COVID-19 pandemic on weight loss of Korean athletes: changes in athletes' physical activity and eating behavior.

Purpose: This study aims to examine the physical activity and eating habits of elite athletes to identify changes in their weight and participation levels in competitions pre- and post-COVID-19, and to establish a database of the abovementioned factors for the post-COVID-19 period.

Methods: This study surveyed 913 elite adult athletes from 22 sports. They were divided into two groups: weight loss athletes' group (WLG) and non-weight loss athletes' group (NWLG).

Gravitational Acceleration Test Results by Lifestyle and Physical Fitness of Air Force Cadets.

The purpose of this study was to analyze G test results according to the Three-Factor Eating Questionnaire (TFEQ), body composition, and physical fitness of fourth-grade air force cadets. This was done to identify the relationship between the TFEQ, body composition, and G resistance, in order to provide basic data for pilots and air force cadets to strengthen G tolerance. From the Republic of Korea Air Force Academy (ROKAFA), 138 fourth-year cadets were assessed using the TFEQ and for body composition and physical fitness.

Functional relationship between the anatomical structures of the calf and athletic ability.

Calf muscle plays an important function in driving the movement of stepping on the ground and moving forward when walking or running. The Achilles tendon has been reported to be closely related to the elasticity of tendons to absorb shock and rebound and convert energy into propulsion. We wanted to determine the effect and correlation of the anatomical structure of the calf region on function.

The c-Abl inhibitor, radotinib induces apoptosis in multiple myeloma cells via mitochondrial-dependent pathway.

Multiple myeloma (MM) is a hematological cancer resulting from accumulated abnormal plasma cells. Unfortunately, MM remains an incurable disease, as relapse is very common. Therefore, there is urgent need to develop new treatment options for MM.

CD45CD34CD38CD133 cells have the potential as leukemic stem cells in acute myeloid leukemia.

Background: Leukemia stem cells (LSCs) in play an important role in the initiation, relapse, and progression of acute myeloid leukemia (AML), and in the development of chemotherapeutic drug resistance in AML. Studies regarding the detection of LSCs and the development of novel therapies for targeting them are extensive. The identification of LSCs and targeting therapies for them has been continuously under investigation.

Radotinib inhibits mitosis entry in acute myeloid leukemia cells via suppression of Aurora kinase A expression.

Aurora kinases play critical roles in regulating several processes pivotal for mitosis. Radotinib, which is approved in South Korea as a second-line treatment for chronic myeloid leukemia, inhibits the tyrosine kinase BCR-ABL and platelet-derived growth factor receptor. However, the effects of radotinib on Aurora kinase expression in acute myeloid leukemia are not well studied.

Effect of Spatone Supplement on Endurance Capacity and Inflammatory Cytokines in a Rapid Weight Control Program in University Wrestlers: A Pilot Study.

In this pilot study, we investigated the effect of spatone, a naturally occurring mineral water supplement, on endurance capacity and inflammatory cytokines in wrestlers undergoing a rapid weight control program. Nine amateur university wrestlers participated and were randomly divided into placebo- and spatone-treated groups. The study used a crossover design, including a 4-week washout period.
