background: this in vitro study investigated the marginal fit of two porcelain laminate veneers to help the selection of more accurate veneers in discolored teeth. materials and methods: thirty impressions of metal master die created from the prepared labial surface of an acrylic maxillary central incisor were made and poured with type iv stone. the dies were distributed into test groups (n = 1...

Objective(s): FOXP3 gene is an X-linked gene that encodes FOXP3 protein, an essential transcription factor in CD4+CD25+FOXP3+ regulatory T (Treg) cells.  We aimed, in the present study, to investigate the association of two FOXP3 polymorphisms, -2383 C/T (rs3761549) and IVS9+459 T/C (rs2280883), with lung cancer. Materials and Methods:  In a case-control study we analyzed genotypes and alleles ...

1. To characterize approaches to fit assessment and identification. 2. To characterize fit maintenance triggers and policies, and factors that should be considered for such decisions.

background and aims. orientation of the occlusal plane is one of the most important clinical procedures in prosthodontic rehabilitation of edentulous patients. the aim of this study was to define the best posterior reference point of ala-tragus line for orientation of occlusal plane for complete denture fabrication. materials and methods. fifty-three dental students (27 females and 26 males) wi...

normal 0 false false false en-us x-none ar-sa previous studies have inspected the associations between adiponectin (adipoq) 276g/t polymorphisms and atherosclerosis, but the results are inconclusive. the aim of this study was to explore the relationship between polymorphism +276 g > t (rs1501299) in adipoq and atherosclerosis. a widespread search was directed to identify all studies on the asso...

background: after lung and prostate cancers, colorectal cancer (crc) is the third most common cancer in men and the second most common cancer in women after breast cancer worldwide. every year, more than one million people are diagnosed with colorectal cancer worldwide and half of these patients die from this disease, making it the fourth leading cause of death in the world. this systematic rev...

Product fit uncertainty (defined as the degree to which a consumer cannot assess whether a product’s attributes match her preferences) is proposed to be a major impediment to online markets with costly product returns and lack of consumer satisfaction. We conceptualize the nature of product fit uncertainty as an information problem and theorize its distinct effect on product returns and consume...

objective(s): foxp3 gene is an x-linked gene that encodes foxp3 protein, an essential transcription factor in cd4+cd25+foxp3+ regulatory t (treg) cells.  we aimed, in the present study, to investigate the association of two foxp3 polymorphisms, -2383 c/t (rs3761549) and ivs9+459 t/c (rs2280883), with lung cancer. materials and methods:  in a case-control study we analyzed genotypes and alleles ...
