BACKGROUND Large nationwide outbreaks of hand, foot, and mouth disease (HFMD) occurred in China from 2008; most of the cases were in children under 5 years. This study aims to identify the situation of natural human enterovirus 71 (HEV71) and coxsackievirus A16 (CVA16) infections in children before 2008 in China. RESULTS Retrospective seroepidemiologic(More)
The incidence of measles in China from 1991 to 2008 was reviewed, and the nucleotide sequences from 1507 measles viruses (MeV) isolated during 1993 to 2008 were phylogenetically analyzed. The results showed that measles epidemics peaked approximately every 3 to 5 years with the range of measles cases detected between 56,850 and 140,048 per year. The Chinese(More)
Skin lightening among Eurasians is thought to have been a convergence occurring independently in Europe and East Asia as an adaptation to high latitude environments. Among Europeans, several genes responsible for such lightening have been found, but the information available for East Asians is much more limited. Here, a genome-wide comparison between(More)
Parkinson's disease is a neurodegenerative disease characterized by the motor symptoms of bradykinesia, tremor, and rigidity. Current therapies are based mainly on dopaminergic replacement strategies by administration of either dopamine agonists or dopamine precursor levodopa (L-Dopa). These treatments provide symptomatic relief without slowing or stopping(More)
The effects of daily dietary Bacillus subtilis (Bs), and adding L-tryptophan, fructan, or casein to fecal fermentation broths were investigated as means to reduce the production of noxious gas during manure fermentation caused by ammonia, hydrogen sulfide (H2S), and 3-methylindole (skatole). Eighty swine (50.0±0.5 kg) were equally apportioned to an(More)
Muscarinic receptors involved in cholinergic neurotransmission were studied in isolated innervated guinea-pig tracheas using preganglionic (nerve) and postganglionic (field) stimulation, after blocking sympathetic effects with bethanidine (5 microM). Neostigmine (10 nM) significantly increased responses to nerve and field stimulation. The M1 antagonist(More)
Adenosine receptor A2A antagonists have emerged as potential treatment for Parkinson's disease in the past decade. We have recently reported a series of adenosine receptor antagonists using heterocycles as bioisosteres for a potentially unstable acetamide. These compounds, while showing excellent potency and ligand efficiency, suffered from moderate(More)
Analyses of an Asian-specific Y-chromosome lineage (O2a1-M95)--the dominant paternal lineage in Austro-Asiatic (AA) speaking populations, who are found on both sides of the Bay of Bengal--led to two competing hypothesis of this group's geographic origin and migratory routes. One hypothesis posits the origin of the AA speakers in India and an eastward(More)
