Recurrence Rate of Herpes Zoster and Its Risk Factors: a Population-based Cohort Study.

Background: Herpes zoster (HZ) is generally thought to occur once in a lifetime and recurrence is considered to be limited to immunocompromised individuals. Although HZ recurrence rates seem to be increasing, there have been few studies exploring these rates in the general population. We investigated the recurrence rate and associated risk factors in the general population.

Repeated Glucose Deprivation/Reperfusion Induced PC-12 Cell Death through the Involvement of FOXO Transcription Factor.

Background: Cognitive impairment and brain damage in diabetes is suggested to be associated with hypoglycemia. The mechanisms of hypoglycemia-induced neural death and apoptosis are not clear and reperfusion injury may be involved. Recent studies show that glucose deprivation/reperfusion induced more neuronal cell death than glucose deprivation itself.

A comparative study of the electromyographic activities of lower extremity muscles during level walking and Pedalo riding.

[Purpose] To analyze the electromyographic (EMG) activities of several lower extremity muscles during ground walking and pedaling using the Pedalo Reha-Bar device. [Subjects and Methods] Fifteen healthy adults aged 20-29 year participated in this study. The subjects' surface EMG signals while walking and Pedalo Reha-Bar riding were recorded.

Ginsenoside Rg3 prevents INS-1 cell death from intermittent high glucose stress.

Background: Ginsenoside Rg3 has been proposed to mediate anti-diabetic effects, but their direct effect on pancreatic β cell viability and mechanisms are not clearly understood. Recent studies suggest that intermittent high glucose (IHG) could be more harmful to pancreatic β cells than sustained high glucose. There are few reports about the effect of the ginsenosideRg3 to β cell apoptosis and proliferation against IHG.

Population-based study of the epidemiology of herpes zoster in Korea.

General epidemiological data regarding herpes zoster (HZ) are necessary for treatment and prevention of this disease. In addition, epidemiological data can play an important role in evaluating the efficacy and impact of vaccination. Though several epidemiological studies of HZ in Korea have been conducted, they usually depend on hospital-based data and may not be representative of HZ characteristics all over Korea.

Co-Culture of α TC-6 Cells and β TC-1 Cells: Morphology and Function.

Background: In vitro experiments using only β-cell lines instead of islets are limited because pancreatic islets are composed of four different types of endocrine cells. Several recent studies have focused on cellular interactions among these cell types, especially α- and β-cells. Because islet isolation needs time and experience, we tested a simple co-culture system with α- and β-cells.

The effect of proton pump inhibitors on glycated hemoglobin levels in patients with type 2 diabetes mellitus.

Objective: Gastrin increases the growth and neogenesis of the islets of Langerhans. Oral proton pump inhibitors (PPIs) increase the circulating gastrin level in animals and humans, but the therapeutic benefit of PPIs for diabetes mellitus has not been resolved. We examined whether treatment with a PPI for ≥2 months affected the glycated hemoglobin (A1C) level in patients with type 2 diabetes.

Diabetic myonecrosis in a patient with hepatitis B-induced liver cirrhosis.

Diabetic myonecrosis-a rare complication of long-standing, poorly controlled diabetes mellitus-typically presents with acute-onset muscle pain, is self-limiting, and responds well to conservative management. We report a case of diabetic myonecrosis in a 33-year-old man with hepatitis B-induced liver cirrhosis and type 2 diabetes who presented with abdominal distension and pain in the left thigh. Diabetic myonecrosis was diagnosed based on clinical presentation, radiological findings, magnetic resonance imaging and histopathological investigations; he was successfully treated conservatively with insulin and analgesics.

Association of low muscle mass and combined low muscle mass and visceral obesity with low cardiorespiratory fitness.

Objective: Previous studies have shown that low cardiorespiratory fitness (CRF), visceral obesity and low muscle mass may share pathophysiological mechanisms, such as insulin resistance and chronic inflammation. In this study, we investigated whether low CRF is associated with low muscle mass, visceral obesity, and visceral obesity combined with low muscle mass.

Research Design And Methods: The associations between CRF and low muscle mass and combined low muscle mass and visceral obesity were examined in 298 apparently healthy adults aged 20-70 years.

A1c variability can predict coronary artery disease in patients with type 2 diabetes with mean a1c levels greater than 7.

Background: Recent studies suggested that the association of acute glucose variability and diabetic complications was not consistent, and that A1c variability representing long term glucose fluctuation may be related to coronary atherosclerosis in patients with type 1 diabetes. In this study, we attempt to determine whether or not A1c variability can predict coronary artery disease (CAD) in patients with type 2 diabetes.

Methods: We reviewed data of patients with type 2 diabetes who had undergone coronary angiography (CAG) and had been followed up with for 5 years.

Pregnancy in postpartum estrus induces inflammatory milk production and catagen specific pup skin inflammation in interleukin-10 deficient mice.

Background: The interleukin 10 deficient mice (IL-10(-/-)) showed high incidence of pup alopecia compared to other strains, and pup alopecia was caused by skin inflammation and was recoverable. Pup alopecia of B6.IL-10(-/-) might be related with maternal factor and interleukin-10 deficient phenotype.

Serum adipocyte fatty acid-binding protein levels are independently associated with sarcopenic obesity.

Aims: Adipocyte fatty acid-binding protein (A-FABP) plays a key role in obesity-related insulin resistance and inflammation which may be involved in the pathogenesis of sarcopenic obesity (SO). This study examined the association of SO with serum A-FABP levels in Korean adults.

Methods: Two hundred ninety eight adults aged 20-70 years were examined using dual X-ray absorptiometry and computed tomography and measuring serum A-FABP levels.

A simple separation method with a microfluidic channel based on alternating current potential modulation.

A simple separation and detection system based on an electrochemical potential modulated microchannel (EPMM) device was developed for the first time. The application of alternating current (AC) potential to the microfluidic separation channel walls, which were composed of screen printed carbon electrodes, resulted in the oscillation and fluctuation of analytes and in the formation of a perfect flat flow front. These events resulted in an increase in the effective concentration and in the fine separation of samples.

Perforated Mitral Valve Aneurysm in the Posterior Leaflet without Infective Endocarditis.

Aneurysm of the mitral valve, although uncommon, occurs most commonly in association with infective endocarditis of the aortic valve and true mitral valve aneurysm is a rare cause of mitral regurgitation. We report a case with perforated mitral valve aneurysm in the posterior leaflet without concurrent infective endocarditis initially mistaken diagnosis of cystic mass, which was confirmed at operation with successful mitral valve annuloplasty.

Effects of Q-switched and long-pulsed 1064 nm Nd:YAG laser on enlarged facial pores.

'Enlarged facial pore' is a subjective term, which is not clearly defined but often complained by many. A diverse range of treatments are used though evidence of efficacy remains largely anecdotal. We report a series of nine patients who underwent a split face trial with Q-switched 1064 nm Nd:YAG and long-pulsed 1064 nm Nd:YAG laser to treat enlarged facial pores.
