statement of the problem: t cells have been shown to play a role in the etiopathogenesis of periodontal disease. b7-h3, a costimulatory molecule, is found to be associated with regulation of t cell function in some tumoral tissues, as well as autoimmune and inflammatory diseases. purpose: the aim of this study was to investigate the expression of b7-h3 molecule in healthy and diseased gingival ...

hydatidosis is a zoonosis disease caused by the larva of echinococcus granulosus parasite in man and animals. the proteases enzymes are necessary for nutrition, migration and evasion of immunity of parasite into host. the aim of this study was to determine the protease activity of hydatid cyst protoscolices (psc), healthy and cystic liver tissues in order to compare of this biomarker for host a...

raditional radiation therapy (RT) typically delivers radiation to a wide target field within the body resulting in the treatment of both the tumor and a significant volume of surrounding healthy tissue. This technology is ideal for tumors that invade the surrounding tissue and when tumor margins are not well defined. In an effort to protect the healthy tissue, traditional RT is delivered in sma...

paecilomyces sp . are saprophytic fungi, which have rarely been pathogen for human. herein, we report a case of cutaneous infection with paecilomyces lilacinus with unusual presentations in a healthy young woman. a biopsy provided an initial diagnosis of fungal elements in the tissue. multiple positive fungal cultures were obtained from the biopsied tissue. microscopic and macroscopic examinati...

introduction: hydatid cyst disease is caused by the protoscolices of echinococcus granulosus. alkaline phosphatase (alp) enzyme is required for metabolism, physiology, immunology, and nutrients absorption in parasite. the aim of this study was to compare the level of alp activity (as a pathological biomarker) in hydatid cyst protoscolices (hcp) with that of sheep liver tissue and to determine t...

BACKGROUND Socioeconomic factors are associated with disparities in oral health among adolescents; however, the underlying reasons are not clear. The authors conducted a study to determine if known indicators of oral health can explain such disparities. METHODS The authors examined data from a 2007 California Health Interview Survey of adolescents. The outcome of interest was self-reported co...

Background Although ovarian tissue cryopreservation and transplantation is used for fertility preservation in patient undergoing cytotoxic treatments but obtaining good quality oocyte is still a debate. Xenotransplantation has been introduced as a reliable technique for better understanding of the transplantation conditions, but to achieve healthy embryos, the quality of obtained oocytes need t...
