Aims: evaluate the differences of infiltration by apical surface after apicoectomy and different kinds root finishing. Materials method: Sixty human cuspids were endodontically treated received apicoectomy, divided in three alleatory groups. Group I no finishing apicoectomy. II standard multifluted bur III same group II, plus brunishing bur. Root surfaces canal coated with nail polishing except...

soil infiltration characteristics affect the design, evaluation and management of furrow irrigation over afield. on the other hand, different variables influence furrow infiltration, making infiltration modeling for afield a complex process. this study was conducted to investigate the direct and indirect effects of allvariables affecting furrow infiltration. the blocked furrow method was used t...

Objective(s): This study was conducted to evaluate the cerebroprotective effect of methanolic leaf extract of Punica granatum (MePG) in Wistar rats.Materials and Methods: The MePG was initially assessed for in vitro antioxidant activity, and later evaluated on LPS-induced RAW 264.7 cell line assay. Finally, the MePG was evaluated against ischemia-reperfusion (I/R) induced brain injury in Wistar...

OBJECTIVE To assess muscle expression of MHC Class I complexes (heavy chain and beta2-microglobulin) and to analyze the composition of infiltrating mononuclear cells, specifically cells that bear receptors for class I MHC molecules, in the muscles of children with early juvenile dermatomyositis (JDM). METHODS Light microscopic and immunohistochemical analysis of muscle biopsies from 10 patien...

Surgical excision of submandibular salivary glands (sialoadenectomy) alters cell turnover in mice liver. Here we show that the liver of adult mice contained scattered leukocyte infiltration foci whose size was in the range of the diameter of hepatocytes. The number of infiltration foci in the liver increased soon after sialoadenectomy and remained high for several weeks. Neutrophils were recrui...

The objective of this study was to directly study a role for mast cells in ischemia-reperfusion (I/R)-induced mucosal and microvascular dysfunction. I/R was induced in the intestine and skeletal muscle (gastrocnemius and cremaster muscle) of wild-type mice and mast cell-deficient mice ( W/ Wv ). Changes in mucosal permeability (blood-to-lumen clearance of51Cr-EDTA), leukocyte infiltration (myel...

Type 1 diabetic patients are diagnosed when beta-cell destruction is almost complete. Reversal of type 1 diabetes will require beta-cell regeneration from islet cell precursors and prevention of recurring autoimmunity. IGF-I expression in beta-cells of streptozotocin (STZ)-treated transgenic mice regenerates the endocrine pancreas by increasing beta-cell replication and neogenesis. Here, we exa...
