Diabetes alters the involvement of myofibroblasts during periodontal wound healing.

Objectives: Myofibroblasts constitute a specific cell phenotype involved in connective tissue healing. Diabetes alters the wound healing response. However, it is not clear whether diabetes modifies the involvement of myofibroblasts in periodontal wounds.

Posology adjustments of oral antineoplastic agents for special populations: patients with renal impairment, hepatic impairment and hematologic toxicities.

Background: Oral antineoplastic agents (OAA) have reached 30-50% of all antineoplastic treatments. Although they seem safer than parenteral therapy, many severe problems can occur if the dose is not adequately adjusted in special situations. Our objective is to create a comprehensive guide with dosage adjustment recommendations for OAA in cases of renal and hepatic impairment and hematologic toxicities.

[Pediatric cardiovascular surgical data base registry in México. First report].

Introduction: Current world tendency is the detection of health problems in order to offer solution alternatives by means of the development of computarized data bases.

Objective: To present the results of a computerized data base developed for the registry of pediatric cardiac surgery with the support of Asociación Mexicana de Especialistas en Cardiopatías Congénitas (AMECC, A.C.

Mexican registry of pediatric cardiac surgery. First report.

Background: Currently, there is a spreading worldwide tendency to characterize health issues and to propose alternative solutions via the creation of computerized databases. The aim of this study was to present the results in a computerized database of pediatric cardiac surgeries developed under the auspices of the Mexican Association of Specialists in Congenital Heart Diseases (Asociación Mexicana de Especialistas en Cardiopatías Congénitas A.C) and coordinated by the collegiate group of Pediatric Cardiology and Surgery as petitioned by the National Institutes of Health and High Specialty Hospitals Coordinating Commission.

Innate immunity modulation by the IL-33/ST2 system in intestinal mucosa.

Innate immunity prevents pathogens from entering and spreading within the body. This function is especially important in the gastrointestinal tract and skin, as these organs have a large surface contact area with the outside environment. In the intestine, luminal commensal bacteria are necessary for adequate food digestion and play a crucial role in tolerance to benign antigens.

Echinococcus granulosus protoscolex formation in natural infections.

Echinococcus granulosus is a parasitic platyhelminth that is responsible for cystic hydatid disease. From the inner, germinal layer of hydatid cysts protoscoleces are generated, which are are the infective forms to the dog. Systematic studies on the cell biology of E.

Changes in the content and distribution of sialic acid on the basal surface of isoproterenol-stimulated mouse parotid acinar cells.

The presence, distribution and content of sialic acid on the cell surface in collagenase-dispersed acini obtained both from unstimulated as well as from in vivo isoproterenol-stimulated mouse parotid have been studied. To this end, sialic acid residues have been qualitatively and quantitatively analyzed by 1) cytochemical labeling by wheat germ agglutinin (WGA), 2) biochemical procedures and 3) isotopic labeling by [3H]WGA (WGA-N-[acetyl-3H]-acetylated). Electron microscopy revealed striking differences in the binding of ferritin-conjugated WGA at the basal, lateral and apical cell surface.
