چکیده سابقه و هدف بازسازی ضایعات استخوانی از اهداف ایده آل درمان های پریو دنتال و ایمپلنتهای دندانی می باشد.بیومتریالهای مختلفی به منظور دستیابی به این هدف استفاده شده و مطالعات زیادی سعی در مقایسه ومعرفی بهترین آن ها داشته است. تحقیق حاضر با هدف بررسی هیستولوژیک و هیستومورفومتریک کاربرد nanocrystalline hydroxyapatite silica gel ، fdba و pdfdb در بازسازی نقائص استخوانی کالواریای خرگوش انجام ...
introduction: the pagat polymer gel dosimeter melts at 30 ˚c and even at room temperature during the summer, so it needs to be kept in a cool place such as a refrigerator. to increase the stability of the pagat gel, different amounts of agarose were added to the pagat gel composition and the pagata gel was manufactured. material and methods: the pagata gel vials were irradiated using a co-60 ma...
conclusions our successful extraction of purified lps from e. coli isolates of uti patients’ urine samples can be an important step to understand the uti disease conditions. results the silver-stained gel demonstrated both smooth and rough type lps by showing trail-like band patterns with the presence and lacking o-antigen region, respectively. coomassie blue staining showed no band assuring th...
background: total body irradiation (tbi) is different from standard radiotherapy in many aspects, so it is not easy to predict the delivered dose to the patient under tbi treatment. diode dosimetry procedures for surface dose reading can help to define variations of the actually delivered dose from the prescribed one. the aim of this study was to describe the measurements made to calibrate diod...
food safety is considered as an important world concern. the detection of pathogen and toxic materials in food has an important role in public health care. in recent years, the applications of microbial biosensor have been developed as a new approach for toxicity control. luminescent microbial biosensor is an appropriate biological tool for protection of natural environment. this type of biosen...
hot-wire spirometer uses a constant temperature anemometer (cta) for its operation. the working principle of cta, used for the measurement of fluid velocity and flow turbulence, is based on convective heat transfer from a hot-wire sensor to a fluid being measured. the calibration curve of a cta is nonlinear and cannot be easily extrapolated beyond its calibration range. therefore, a method for ...
The cobalt glycyl-leucine dipeptide is a model system for studying the effects of Karplus equation calibration, molecular mechanics accuracy, backbone conformation, and thermal motions on the measurability of side chain rotational isomer populations. We analyze measurements of 8 vicinal coupling constants about the α to β-carbon and β to γ-carbon bonds of the leucine side chain and of 10 NOESY ...
A specific, precise and stability indicating high-performance thin-layer chromatographic method for simultaneous estimation of pantoprazole sodium and itopride hydrochloride in pharmaceutical formulations was developed and validated. The method employed TLC aluminium plates precoated with silica gel 60F254 as the stationary phase. The solvent system consisted of methanol:water:ammonium acetate;...
When carbonaceous pitches are used as raw materials for advanced carbon products, the molecular composition of the pitch acquires special importance. Not only does molecular composition affect the physical properties (e.g., softening point and viscosity) of the pitch, but it also affects the final properties, such as the strength and thermal conductivity, of the resultant carbon products. Unfor...
