  • Human Caliciviruses Are a Significant Pathogen of Acute Sporadic Diarrhea in Children of Santiago, Chile

    Human caliciviruses (HuCVs) are increasingly recognized as common pathogens that cause acute sporadic diarrhea in children; however, regional antigenic and genetic diversity complicate detection techniques. Stool samples from children seeking medical attention in 2 outpatient clinics, a large emergency department, and 2 hospital wards were evaluated for HuCVs by reverse transcription—polymerase chain reaction, using primers based on a conserved sequence of the polymerase region of a previously sequenced Chilean strain. HuCVs were detected in 53 (8%) of 684 children 1 month to 5 years of age (mean, 13 months). Detection occurred year-round without a clear seasonal peak, and detection frequency declined from 16% in 1997 to 2% in 1999. The decline may have been due to a change in virus genotype. HuCVs are a significant pathogen of acute sporadic diarrhea in Chilean children, and continuous characterization of genetic diversity will be crucial for appropriate detection.
    人杯状病毒(HuCVs)作为一种常见的病原体,导致儿童急性散发性腹泻的作用日益受到重视;然而,其抗原性和遗传学的区域多样性复杂化了检测技术。本研究采用逆转录-聚合酶链反应,以基于先前智利分离株的聚合酶区域保守序列设计的引物,对两所门诊诊所、一家大型急诊科和两家医院病房中因病就诊的儿童粪便样本进行了HuCVs检测。在684名1个月至5岁的儿童中(平均年龄13个月),有53名(8%)检出HuCVs。检测全年均有发生,无明显季节高峰,且检出频率从1997年的16%下降至1999年的2%。这种下降可能归因于病毒基因型的改变。HuCVs是智利儿童急性散发性腹泻的重要病原体,而持续对遗传多样性进行表征对于正确检测至关重要。

    The present invention discloses a radioisotope 18 F substituted thiamine, synthesis method, and use thereof in small animal PET/CT imaging. The radioisotope 18 F substituted thiamine has a structure of The synthesis method comprises radiochemical synthesis by using existing precursors. In the present invention, the hydroxyl in the hydroxyethyl on the thiazole cycle of thiamine is replaced by radioisotope 18 F, to prepare a PET tracer. The radioisotope 18 F substituted thiamine of the present invention successfully enters the brains of various strains of mice, and the uptake in the brains of thiamine-deficient mice is obviously greater than that in normal control. The present invention is useful in the preparation of a brain imaging tracer for clinical trials of Alzheimer's disease and tumors.

    Some neuropsychological diseases are associated with abnormal thiamine metabolism, including Korsakoff–Wernicke syndrome and Alzheimer’s disease. However, in vivo detection of the status of brain thiamine metabolism is still unavailable and needs to be developed. A novel PET tracer of 18F-deoxy-thiamine was synthesized using an automated module via a two-step route. The main quality control parameters
