background: this study sought to assess symphyseal morphology in adolescents with different mandibular growth patterns (mgps) in order to see if a relation exists. materials and methods: in this study the symphyseal parameters (height, depth, and ratio) of normal subjects were compared with four groups with malocclusion (cl iii vertical, cl ii vertical, cl iii horizontal, and cl ii horizontal)....

background to achive natural and harmonic restoration color, shade matching is a commonly used method in dental practice using shade guides. to prevent infection,shade guides are required to be disinfected .using of disinfection solutions gradually affect the color of dental equipment. the aim of this study was to evaluate the effect of three disinfectants sodium hypochlorite solution 5/25%, de...

OBJECTIVE Excessive pressure due to wearing mal-adapting dentures is well known to cause residual bone resorption beneath the denture. X-rays have been commonly utilized to evaluate the changes in the bone beneath the denture. However, X-ray images merely detect bone density and relatively large changes in the bone shape and structure, whereas nuclear medicine imaging can detect functional chan...

Background and Aim: Atherosclerosis is known as a multifactorial inflammatory disease. Trimethylamine N-oxide (TMAO) as a risk factor, has a potential to trigger or enhance the immune inflammatory reactions in atherosclerosis. Yet, The exact mechanism by which TMAO induces inflammation during atherosclerosis is not well understood. The present study was designed to evaluate the expression of IL...

Peptic ulcer is one of the most prevalent gastrointestinal disorder, commonly occurs in developed countries. The present work was carried out to evaluate antiulcer effect of Ipomoea batatas (L) dietary tuberous roots. The Ethanolic extract of Ipomoea batatas (EEIB) was prepared by dynamic maceration for 7 days at room temperature using 70% ethanol (V/V). The antiulcer activity was evaluated...

Background: It is known that acetylation level of the nuclear histones in cloned embryos is lower compare to normally developed embryos. Histone deacetylas inhibitors (HDACi) with improvement of acetylation level in these embryos can affect embryo quality in pre-implantation stage and expression level of different genes especially developmental genes. Materials and Methods: In this research, SA...

Abstract Background Opioid drugs are used to treat pain in inflammatory bowel disease (IBD) but their side effects can cause serious morbidity. Therefore, we tested a novel opioid analgesic, ±)-N-(3-fluoro-1-phenethylpiperidine-4-yl)-N-phenylpropionamide (NFEPP) which selectively activates peripheral µ-opioid receptors at acidic pH, as occurs inflamed tissue. Aims Evaluate whether NFEPP causes ...
