Lower Respiratory Tract Infection with Human Metapneumovirus: Chest CT Imaging Features and Comparison with Other Viruses.

Purpose: Human metapneumovirus has been increasingly identified as a cause of lower respiratory tract infection in adults worldwide. The CT imaging features of human metapneumovirus in adults have not been characterized. The purpose of this paper is to determine the imaging features of human metapneumovirus and to compare them with features of other viruses.

Pain during and after-hernioplasty in raquidian or locorregional anesthesia by locking peripheral nerves.

Purpose: To analyze pain scores after surgery in a group of patients submitted to inguinal hernia repair under peripheral nerve block with local or spinal anesthesia.

Methods: Fifty patients were divided into two groups (both with 25 patients each). In the first group the patients were submitted to herniorrhaphy under peripheral block and local anesthesia (LG) and in the other group the patients were submitted to the same procedure under spinal anesthesia (RG).

Small pulmonary artery defects are not reliable indicators of pulmonary embolism.

Objectives: To evaluate the rate of agreement of pulmonary embolism diagnosis in computed tomography (CT) pulmonary angiogram studies and to evaluate the rate of inaccurate interpretations in the community hospital setting.

Methods: Using the keywords "pulmonary embolism/embolus/emboli," the radiology information system was searched for CT pulmonary angiograms performed over a 3-year period at three U.S.

WY-50,295 tromethamine, a novel, orally active 5-lipoxygenase inhibitor: biochemical characterization and antiallergic activity.

WY-50,295 tromethamine demonstrates significant 5-lipoxygenase inhibitory activity with IC50 values ranging from 0.055 microM in rat peritoneal exudate cells, to 0.16 microM in mouse macrophages, 1.

Characterization and pharmacological modulation of soluble phospholipase A2 generated during glycogen-induced rat peritonitis.

Soluble phospholipase A2 (PLA2) activity was assessed in rat peritoneal lavage fluid after an intraperitoneal injection of 6% glycogen. Enzyme activity immediately increased 5-fold above basal by 4 h. Activity decreased by only 30% at 18 h and remained at this elevated level through 72 h.
