A cold-adapted (ca) influenza B reassortant virus vaccine that contained the six internal RNA segments from influenza B/Ann Arbor/1/66 ca virus and the neuraminidase and hemagglutinin genes from wild-type influenza B/Texas/1/84 virus was evaluated in children ranging in age from 8 months to 14 years. The children were vaccinated intranasally with doses ranging from 10(3.2) to 10(6.2) 50% tissue...

A total of 300 gastric biopsy samples and 50 Helicobacter pylori isolates were collected from Ethiopian adult dyspeptic patients. The vacA and cagA genes were detected in 90 and 79% of biopsy specimens, respectively, and in 100 and 87% of clinical isolates, respectively. Both genes were detected in 84% of the gastric biopsy samples and in 87% of the clinical isolates. Among vacA genotypes, the ...

STUDY OBJECTIVE To determine the ability of emergency department (ED) physicians to diagnose cholelithiasis with bedside ultrasound. METHODS ED gallbladder ultrasounds recorded over 37 months were compared to radiology ultrasound interpretation. RESULTS Of 1,690 ED gallbladder ultrasound scans performed during this period, radiology ultrasound was performed in 575/1690 (34%) cases. ED physi...

The enantioselective synthesis of Anomala osakana pheromone and Janus integer pheromone has been achieved without using any protecting groups. The synthesis involved using an asymmetric alkynylation to obtain gamma-hydroxy-alpha,beta-acetylenic esters with high ee (84%) and yields ( approximately 80%), followed by selective hydrogenation and lactonization in high overall yields (87% and 89%).

The complete genome sequence of a new isolate of squash mosaic virus (SqMV) infecting squash plants in Spain was obtained using deep sequencing of small RNAs. The low nucleotide sequence identities, with only 87 to 88% for RNA1 and 84 to 86% for RNA2 to known SqMV isolates, suggested that this isolate belongs to a novel genotype.

OBJECTIVES To compare the accuracy of transvaginal sonography (TVS) and magnetic resonance imaging (MRI) in the preoperative staging of endometrial carcinoma. METHODS This was a prospective study in which 74 women consecutively diagnosed with endometrial carcinoma were examined using TVS by physicians trained in gynecological sonography and MRI by radiologists with a special interest in gynec...
