The effects of orthodontic movement on a subepithelial connective tissue graft in the treatment of gingival recession.

Aim: The purpose of this article is to report on the five-year follow-up of a case involving treatment of gingival recession with a subepithelial connective tissue graft prior to orthodontic tooth movement.

Background: Gingival recession has a global prevalence that varies from 3 to 100 percent depending on the population studied and the method of analysis. In addition, the frequency of recession seems to be positively correlated with age.

Exhaustive computational identification of pathogen sequences far-distant from background genomes: Identification and experimental verification of human-blind dengue PCR primers.

We recently developed novel algorithms for exhaustive identification of all nucleotide subsequences present in a pathogen genome which differ by at least a chosen number of mismatches from the sequences of host/background organisms. This type of exhaustive computational analysis will be useful in reducing false positives and cross-reactivity in PCR and hybridization assays. We present the first experimental test of the method by showing that the subsequences identified when used as 18-mer PCR primers can detect the presence of dengue virus (DENV) even in the presence of a large excess of complex human genomic DNA.

[Upper digestive hemorrhage in patients older than 60 years of age].

We reviewed 286 records of patients older than 60 years with upper GI bleeding from 1985 to 1990. The average age was 72.7 +/- 8.

[Indomethacin in the treatment of acute cholecystitis and biliary colic].

Prostaglandins GE2 produces on the gallbladder a rise in intraluminal pressure, an increase in in intraluminal secretion, improves gallbladder contraction and decreases its absorption capacity. In this study, patients who received indomethacin twice a day by rectum, showed a significant reduction in volume and area of gallbladder after 24 and 48 hours (P < 0.05).
