#1
Hwa-Jung Choi
Human rhinoviruses and enteroviruses (family Picornaviridae) infect millions of people worldwide each year, but little is known about effective therapeutical treatment for the infection caused by these viruses. We sought to determine whether or not Zanthoxylum (Rutaceae) species can exhibit antiviral activity against picornaviruses. The leaf parts of four Zanthoxylum species were extracted with methanol, and the extracts were investigated for their antiviral activity against picornaviruses using cytopathic effects by cytopathic effect reduction...

OBJECTIVES: To understand the illness experience of patients with chronic hepatitis C participating in clinical trials in the sociocultural context of Korea in an in-depth and comprehensive manner. METHODS: A focused ethnography approach was used to discover the pattern of illness experience of patients with chronic hepatitis C in the cultural background of Korea. Interviews were conducted with 11 patients with chronic hepatitis C participating in clinical trials and the collected data were analyzed with the domain analysis, taxonomical analysis, componential analysis, and theme analysis proposed by Spradley...

OBJECTIVES: The purpose of this study was to quantify the time-varying changes in pulmonary function with exposure to prolonged sitting. METHODS: Twenty-one healthy volunteers were recruited. The pulmonary function of all participants was measured three times in order to assess changes over time; pulmonary function was measured before sitting, after participants had been seated for 1 hour, and after they had been seated for 2 hours. A spirometer was used to measure pulmonary function...

OBJECTIVES: The purpose of this study was to determine whether obesity is associated with less postural stability in young adults, and whether it is influenced by anterior pelvic tilt angle and sensory dysfunction. METHODS: Center of gravity (COG) velocity and total sway distance with eyes open or eyes closed on firm or foam floors were determined in 12 obese individuals and 12 individuals with normal weight. RESULTS: On firm and foam floors with eyes closed, center of gravity velocity and total sway distance were significantly greater in the obese group than in the normal-weight group...

OBJECTIVES: One of the most common head and neck cancers is nasopharynx cancer. Knowledge about the incidence and mortality of this disease and its distribution in terms of geographical areas is necessary for further study and better planning. Therefore, this study was conducted with the aim of determining the incidence and mortality rates of nasopharynx cancer and its relationship with the Human Development Index (HDI) in Asia in 2012. METHODS: The aim of this ecologic study was to assess the correlation between age-specific incidence rate (ASIR) and age-specific mortality rate (ASMR) with HDI and its components, which include the following: life expectancy at birth, mean years of schooling, and gross national income per capita...

OBJECTIVES: High-risk human papillomavirus (hrHPV) is known to be a representative cancer-causing agent in the genital and head and neck regions. Many studies have detected hrHPV DNA in nonsmall cell lung carcinoma. However, hrHPV-etiologic correlation in nonsmall cell lung carcinoma remains unclear. This study is designed to determine the prevalence of episomal or integrated hrHPV DNA in nonsmall cell lung carcinoma among the Korean population. METHODS: Surgically resected nonsmall cell lung carcinoma tissues, including 134 cases of squamous cell carcinoma (SqCC) and 99 cases of adenocarcinoma (ADC), were examined...

OBJECTIVES: Progastrin-releasing peptide (proGRP) is a promising biomarker for small cell lung cancer. However, not much is known about how sample processing and storage conditions affect the stability of proGRP. Here, we examined the effects of repeated freeze-thaw cycles on the stability of proGRP in plasma and serum. METHODS: Concentrations of proGRP were measured in plasma and serum samples exposed to two, three, or four freeze-thaw cycles and these were compared with values of corresponding samples exposed to one cycle (baseline)...

OBJECTIVES: Identification of the causal impact of self-esteem on smoking stages faces seemingly insurmountable problems in observational data, where self-esteem is not manipulable by the researcher and cannot be assigned randomly. The aim of this study was to find out if weaker self-esteem in adolescence is a risk factor of cigarette smoking in a longitudinal study in Iran. METHODS: In this longitudinal study, 4,853 students (14-18 years) completed a self-administered multiple-choice anonym questionnaire...

OBJECTIVES: Fishermen are among the most vulnerable groups for human immunodeficiency virus (HIV)/AIDS with reported high prevalence. Poor knowledge base has been evidenced by a few studies. The present study was conducted to assess the knowledge regarding HIV/AIDS among fishermen of the Kutch coast, Gujarat, India. METHODS: A descriptive cross-sectional study was conducted among 950 fishermen of the Kutch coast, in the months of January-February 2015. Knowledge of HIV/AIDS of fishermen was assessed using structured interview schedules with 12 questions...

OBJECTIVES: Keloid and hypertrophic scars are abnormal manifestations of wounds that occur following skin injuries in the form of local proliferation of fibroblasts and increased production of collagen. There are several ways to cure these scars; treatment must be selected based on the nature of the scars. In this clinical trial, two methods-cryotherapy and intense pulsed light (IPL)-are compared in the treatment of scars, and the results are presented in terms of improvement level, complications, and patient satisfaction...

OBJECTIVES: Escherichia coli is regarded as the most important etiological agent of urinary tract infections. Fluoroquinolones are routinely used in the treatment of these infections; however, in recent years, a growing rate of resistance to these drugs has been reported globally. The aims of this study were to detect plasmid-mediated qnrA, qnrB, and qnrS genes among the quinolone-nonsusceptible E. coli isolates and to investigate their clonal relatedness in Qazvin and Zanjan Provinces, Iran...

OBJECTIVES: Production of carbapenemase, especially Klebsiella pneumoniae carbapenemases (KPC), is one of the antibiotic resistance mechanisms of Enterobacteriaceae such as Klebsiella oxytoca. This study aimed to investigate and identify KPC-producing K. oxytoca isolates using molecular and phenotypic methods. METHODS: A total of 75 isolates of K. oxytoca were isolated from various clinical samples, and were verified as K. oxytoca after performing standard microbiological tests and using a polymerase chain reaction (PCR) method...

OBJECTIVES: To determine the prevalence of retinopathy and its associated factors in diabetic patients referred to a diabetes center in an Iranian city. METHODS: This was a cross-sectional, descriptive-analytical study in which a researcher-made checklist was used to collect the data of patients with type 2 diabetes in 2015. The statistical population consisted of 11,770 health records of diabetic patients registered in a second-level diabetes center.

OBJECTIVES: The aim of this study was to identify the correlation between adequate water intake and the prevalence of metabolic/heart diseases. METHODS: We analyzed the data from the 2012 Korea National Health and Nutrition Examination Survey. All participants were divided into Group Above Adequate Intake (n = 736) and Group Below Adequate Intake (n = 4,819) according to water intake. The thresholds were 1.8 L for men and 1.4 L for women based on the World Health Organization report findings...
