The QT interval, apart from clinical implications is crucial for safety assessment of new drugs under development. A QTc prolongation of even 10 msec in a study group is a warning signal for a new drug. There are various issues involved in the measurement of the QT interval especially regarding the ending of the T wave and different morphological pattern of T-U complex. The other issue is signi...

Prey size is an important factor in food consumption. In studies of feeding ecology, prey items are usually measured individually using calipers or ocular micrometers. Among amphibians and reptiles, there are species that feed on large numbers of small prey items (e.g. ants, termites). This high intake makes it difficult to estimate prey size consumed by these animals. We addressed this problem...

Background: One of the most significant factors in the success of dental implant procedures, can be mentioned by the quality and quantity of jaw bone. The occurrence of some problems such as trauma, infection, pathological lesions and the long-term absence of teeth in patients, it causes irregularities in the jaw bone and can get bone resorption. Sever defects after trauma or tumor resection ne...

Introduction: Gold standard for alveolar cleft bone grafting is autogenous bone. Advantage of adding the growth factors to the bone is established, so adding PRF to the autogenous bone may have beneficial effects. Methods:  Platelet-rich plasma admixed with autogenous bone and as a biologic membrane over the bone grafted alveolar cleft was used. Results:  Autogenous bone in all (four cases...

Background Trapidil is an antiplatelet drug with specific platelet-derived growth factor antagonism and antiproliferative effects in the rat and rabbit models after balloon angioplasty. Methods and Results The Studio Trapidil versus Aspirin nella Restenosi Coronarica (STARC) is a multicentric, randomized, double-blind trial to assess the effects of trapidil in angiographic restenosis prevention...

Transplants of tumors were made in the lower right hind leg, and treatment was begun when the tumor volume was 150-200 mm.3 For lymphosarcoma, this was 12 to 16 days; for mammary carcinoma A ? 179955, 10 to 15 days; for mammary carcinoma 5769, 10 to 15 days; and for solid Erlich ascites tumor, 6 to 8 days after inoculation. Both mammary carcinomas were spontaneous in Strain A mice obtained from...

The contribution of software to the uncertainty of measurements is an important but often overlooked aspect of uncertainty evaluations. In coordinate metrology, software is often relied upon for complicated fitting of data, filtering, calibrations, and statistical calculations. Metrology equipment using software can range from hand-held digital calipers to coordinate measurement machines spanni...

A method for measuring canine heart size in radiographs was developed on the basis that there is a good correlation between heart size and body length regardless of the conformation of the thorax. The lengths of the long and short axes of the heart of 100 clinically normal dogs were determined with calipers, and the dimensions were scaled against the length of vertebrae dorsal to the heart begi...
