Effect of receptor specificity of A/Hong Kong/1/68 (H3N2) influenza virus variants on replication and transmission in pigs.

Background: Several arguments plead for an important role of pigs in human influenza ecology, including the similar receptor expression pattern in the respiratory tract of both species. How virus receptor binding specificity affects transmission in pigs, on the other hand, has not been studied so far.

Objectives:   Using recombinant viruses R1-HK, which harbored all genes from the original pandemic virus A/Hong Kong/1/68 (H3N2), and R2-HK, which differed by L226Q and S228G mutations in the hemagglutinin and conversion to an avian-virus-like receptor specificity, we assessed the role of receptor specificity on (i) replication in porcine respiratory explants, (ii) pig-to-pig transmission, and (iii) replication and organ tropism in pigs.

Randomized adjuvant study comparing two schemes of 5-fluorouracil and leucovorin in stage B2 and C colon adenocarcinoma: study design and preliminary safety results. Groupe d'Etude et de Recherche Clinique en Oncologie Radiotherapies.

The aim of this randomized open-label study was to compare a bimonthly with a monthly regimen of 5-fluorouracil (5-FU) and leucovorin for the adjuvant treatment of colon and high-rectum adenocarcinoma. The bimonthly regimen was administered for 2 consecutive days every 14 days as d,L-leucovorin 200 mg/m2 or L-leucovorin 100 mg/m2 as a 2-hour infusion followed by 5-FU bolus of 400 mg/m2 and a 600 mg/m2 5-FU 22-hour continuous infusion (LVSFU2). In the monthly regimen, d,L-leucovorin 200 mg/m2 or L-leucovorin 100 mg/m2 15-minute infusion followed by a 400 mg/m2 15 minute 5-FU bolus was administered for 5 consecutive days every 28 days (FUFOL).

[Cardiac hydatidosis: contribution of magnetic resonance imaging. Report of a case].

Cardiac hydatid cyst is a rare condition. The diagnosis is difficult and is based on a series of findings amongst which hydatid serology and cardiac imaging play important parts. The values and limitations of echocardiography, coronary angiography and CT scanning are well known.

Nosocomial infections associated with long-term radial artery cannulation.

From January 1987 to December 1987, 193 radial artery cannulations were performed in 112 patients (87 males, 25 females; mean age = 57.5 years). The mean duration of cannulation was 6.

[Enterobacter, Serratia, Acinetobacter or Pseudomonas septicemias].

During 1985 and 1986, 48 bacteremias due to Enterobacter spp, Acinetobacter spp, Serratia spp or Pseudomonas spp were collected by the SES Group. The mortality rate of those infections due to multiresistant organisms appeared high (27.9%).
