Extreme climatic activities, such as typhoons, are widely known to disrupt our natural environment. In particular, studies have revealed that typhoon-induced perturbations can result in several long-term effects on various ecosystems. In this study, we have conducted a 2-year metagenomic survey to investigate the microbial and viral community dynamics(More)
BACKGROUND This study aimed to investigate the risk factors associated with post-traumatic stress disorder (PTSD) symptoms in a mid- and old-age population who experienced Typhoon Morakot in Taiwan. METHODS One hundred and twenty people, who were mostly Taiwanese aboriginal people aged 55 years and above, were invited to participate in this study. PTSD(More)
OBJECTIVE This study was designed to investigate the relationship between the treatment effect of olanzapine and the serum prolactin level in schizophrenia and to investigate the factors that may act as predictors of response for olanzapine treatment. METHOD Sixty patients who met the DSM-IV criteria for schizophrenia were included in the study. None of(More)
This longitudinal study investigated the prevalence, predictors, and related factors for Internet addiction among elementary and junior high school students in Taiwan. A convenient sample of grades 3, 5, and 8 students (n = 1153) was recruited from six elementary and one junior high schools. They were assessed during the beginning and the end of the spring(More)
Although the literature has documented associations between sleep problems and internet addiction, the temporal direction of these relationships has not been established. The purpose of this study is to evaluate the bidirectional relationships between sleep problems and internet addiction among children and adolescents longitudinally. A four-wave(More)
Analysis of urinary N7-(benzo[a]pyren-6-yl)guanine (BP-6-N7Gua), a DNA adduct induced by benzo[a]pyrene, may serve as a risk-associated biomarker for exposure to polyaromatic hydrocarbons (PAHs). In this study a highly sensitive and specific analytical method, incorporating on-line sample preparation coupled with isotope-dilution liquid chromatography and(More)
Prokaryotic microbes, the most abundant organisms in the ocean, are remarkably diverse. Despite numerous studies of marine prokaryotes, the zonation of their communities in pelagic zones has been poorly delineated. By exploiting the persistent stratification of the South China Sea (SCS), we performed a 2-year, large spatial scale (10, 100, 1000, and 3000 m)(More)
Steroid hormones, such as androgens, are common surface-water contaminants. However, literature on the ecophysiological relevance of steroid-degrading organisms in the environment, particularly in anoxic ecosystems, is extremely limited. We previously reported that Steroidobacter denitrificans anaerobically degrades androgens through the 2,3-seco pathway.(More)
