Introduction: Pulmonary hypertension has been associated with a significant increase in morbidity and mortality. The pulmonary artery diameter measurement from CT scan is routinely used to predict possible evidence of hypertension. However, no data available as reference for the normal range, especially Thai Population. primary purpose this study was determine main (MPA) ascending aorta (AAo) r...

turbulent mixed convection of a nanofluid (water/al2o3, φ=.02) has been studied numerically. two-phase mixture model has been used to investigate the effects of nanoparticles mean diameter on the flow parameters. nanoparticles distribution at the tube cross section shows that the particles are uniformly dispersed. the non-uniformity of the particles distribution occurs in the case of large nano...

the geometric mean particle diameter (dg) and lime are two of the most important properties from the viewpoint of soil management. nowadays remote sensing technology which has emerged walking with science development throughout the world, has made soil study faster, more facile and more cost-efficient. an investigation of soil dg and lime was performed in pol-e-dokhtar area by use of four sets ...

Normal values of the antero-posterior diameter of the head of the pancreas are of utmost value in radiological practice. With more than 60% of diseases and tumours of the pancreas occurring in its head, knowledge of its normal size is essential to the clinician. Computed tomography (CT) is the most effective technique for the diagnosis and staging of pancreatic carcinoma and magnetic resonance ...

OBJECTIVE The aim of the study reported here was to investigate the protective effect of gonadotropin-releasing hormone analog (GnRHa) against cyclophosphamide (CTX)-induced gonadotoxicity. METHODS Eighty Fischer 344 rats were divided randomly into four groups (20 per group). One group received normal saline, one GnRHa, one CTX, and one GnRHa+CTX. Several parameters were used to observe the o...

This study technically assessed the WHO-621 periodontal probe made in Brazil as well as its dimensional and weight stability after sterilization. The following characteristics were measured in one hundred (100) new probes: diameter and linear area of tip sphere and beginning and ending references of its colored band by means of indirect computerized morphometric method, and weight, by means of ...

BACKGROUND Craniofacial abnormalities and increased pharyngeal collapsibility due to abnormal connective tissue suggest the possibility of an increased prevalence of obstructive sleep apnoea (OSA) in patients with Marfan's syndrome but the actual prevalence is uncertain. Aortic dilatation and dissection are life threatening manifestations of Marfan's syndrome and case reports have suggested a p...

we collected the specimens of turcinoemacheilus hafezi throughout the spawning season (january to july, 2012) in beshar river (south-west iran) and investigated its age, growth, and reproductive characteristics. the maximum age was 2 + years. total length and weight of the specimens ranged from 29 to 61 mm and 0.17 to 1.39 g, respectively. length-weight relationship was estimated as w = 3e-05tl...
