Involvement of the transcription factor E75 in adult cuticular formation in the red flour beetle Tribolium castaneum.

Insect adult metamorphosis generally proceeds with undetectable levels of juvenile hormone (JH). In adult development of the red flour beetle Tribolium castaneum, biosynthesis of adult cuticle followed by its pigmentation and sclerotization occurs, and dark coloration of the cuticle becomes visible in pharate adults. Here, we examined the molecular mechanism of adult cuticular formation in more detail.

[Antibiotic resistance of Helicobacter pylori in Reunion Island: therapeutic consequences].

The aims of this paper were to assess resistance of Helicobacter pylori to antibiotics included in the so-called French triple regimens and to identify the possible causes of therapeutic failure in Reunion island. Antibiotic resistance was determined for 109 strains. All the strains were sensitive to amoxicillin and tetracycline, 93.

[Seasonal trends of respiratory syncytial virus infections on Réunion Island gathering data among hospitalized children].

Little is known about the epidemiology of respiratory syncytial virus (RSV) infections in tropical countries and in particular in tropical islands of the Indian Ocean. Our study reviewed all cases of RSV infections diagnosed among hospitalized children in the Hospital de Saint Pierre de la Réunion, from January 1993 to December 1999. 849 cases were identified of which 67.

Comparison of three non-nested RT-PCR for the detection of influenza A viruses.

Background: The viral isolation technique (VIT) is largely used as a gold standard for the detection of influenza A and B viruses in respiratory samples. Some recent studies have pointed out that the polymerase chain reaction (PCR) assays allow sensitive and rapid detection of influenza viruses, also providing excellent correlation with traditional methods.

Objectives And Design Study: The aim of this study was to evaluate the efficiency of three non-nested PCR, two PCR-hybridization assays using primers defined in M and NS genes, and one PCR which uses primers defined in NP, NS and HA genes and combines the detection of H3N2 and H1N1 hemagglutinin genes using defined primers in NP, NS and HA genes (PCR3), in comparison with an IF assay (IFA) and viral isolation technique (VIT).

[Clinical study of white atrophy: the viewpoint of the phlebologist].

After giving a clinical description of Millian's white atrophy, its preferred locations and the area in which it develops (post-phlebitic or non-post-phlebitic chronic venous deficiency), the author distinguishes: a benign, non-evolutive form; forms of pseudo white atrophy, of identical morphology, of different development in which a tableau of acute inflamed hypodermititis develops towards hyperalgic ulceration; intermediate forms of more chronic development; non-evolutive forms, such as certain ulcer scars. If it is impossible to predict the developmental capacity of a plaque of white atrophy, it is nevertheless crucial to prescribe in all cases a well adapted elastic support, as this is the only way to avoid the majority of complications and, sometimes, to obtain a certain degree of reversibility.
