Appropriate Resistance Intensity and Effective Exercise for Activation of Infraspinatus.

We investigated the muscle activities of the infraspinatus and posterior deltoid, as well as the ratio of the infraspinatus to posterior deltoid muscle activities, in response to 3 resistance intensities during prone external rotation (PER) and sitting external rotation (SITER) exercises. Fifteen healthy males participated; the subjects performed two exercises randomly at three resistance intensity levels: 1) low intensity (10-20%); 2) medium intensity (45-55%); 3) high intensity (60-70%). Surface electromyography was used to measure the activities of the infraspinatus and posterior deltoid muscles.

The effects of prism glasses and intensive upper limb exercise on hemineglect, upper limb function, and activities of daily living in stroke patients: a case series.

[Purpose] This study aimed to examine the effects of visual field with prism glasses, and intensive upper limb functional training on reduction of hemineglect and improvement in upper limb function and activities of daily living in three stroke patients with hemineglect. [Subjects] This study included three stroke patients hospitalized in a sanatorium. [Methods] Intervention treatment involving prism glass use for 12 hours and 30 minutes and paretic side upper limb training was conducted 5 days a week for 15 weeks.

Long QT syndrome: a Korean single center study.

The long QT syndrome (LQTS) is a rare hereditary disorder in which affected individuals have a possibility of ventricular tachyarrhythmia and sudden cardiac death. We investigated 62 LQTS (QTc ≥ 0.47 sec) and 19 family members whose genetic study revealed mutation of LQT gene.

Oscillating pressure treatment upregulates connexin43 expression in skeletal myoblasts and enhances therapeutic efficacy for myocardial infarction.

Transplantation of autologous skeletal myoblasts (SMBs) is a potential therapeutic approach for myocardial infarction. However, their clinical efficacy and safety is still controversial. Electrical coupling through gap junction between SMBs and host myocardium is essential for synchronized contraction and electrical stability.

Analysis of genetic and non-genetic factors that affect the QTc interval in a Mongolian population: the GENDISCAN study.

The QTc interval is a complex quantitative trait and a strong prognostic indicator of cardiovascular mortality in general, healthy people. The aim of this study was to identify non-genetic factors and quantitative trait loci that govern the QTc interval in an isolated Mongolian population. We used multiple regression analysis to determine the relationship between the QTc interval and non-genetic factors including height, blood pressure, and the plasma lipid level.

[The long-term follow-up results after steroid treatment in patients with autoimmune chronic pancreatitis].

Background/aims: Autoimmune chronic pancreatitis (AIP) is a clinically attractive entity because of its dramatic response to steroid therapy. But the long-term results after steroid therapy have not been reported yet in Korea. The purpose of this study was to assess the long-term results and prognosis after steroid therapy in patients with AIP.

[Clinical features of fulminant hepatic failure in a tertiary hospital with a liver transplant center in Korea].

Background/aims: Striking geographic differences have been noted in the etiology of fulminant hepatic failure (FHF). The prognosis of patients with FHF who do not receive liver transplantation in a timely manner is quite dismal. This study intended to identify the etiology and outcome of FHF in Korean adults and to examine the role of urgent living-donor liver transplantation (LDLT) for treating this unique situation.
