-A new species ofaxiid, Eutrichocheles pindatyba, is described from Santa Cruz, south-central Brazil. The species is characterized by possessing a laterally dentate rostrum, unarmed median and submedian carinae of the carapace, spinose ischia and meri and tuberculate propodi of the first pereopods. The genus Eutrichocheles was erected by Wood Mason (1876), to accommodate Cancer modestus Herbst,...

PURPOSE The aim of this study was to analyze the oncologic outcomes and the risk factors for recurrence after a tumor-specific mesorectal excision (TSME) of resectable rectal cancer in a single institution. METHODS A total of 782 patients who underwent a TSME for resectable rectal cancer between February 1995 and December 2005 were enrolled retrospectively. Oncologic outcomes included 5-year ...

Uridine 5'-triphosphate (UTP) increases chloride secretion followed by fluid movement into the proximal airspaces. However, little is known about whether UTP affects fluid movement in the distal airspaces. We studied the effect of UTP on basal and stimulated alveolar fluid clearance in the isolated rat lungs. Isosmotic 5% albumin solution was instilled into the alveolar spaces of isolated rat l...

BACKGROUND AND OBJECTIVES Gitelman syndrome (GS) is a salt-wasting tubulopathy that results from the inactivation of the human thiazide-sensitive sodium chloride cotransporter located in the distal convoluted tubule. Tubular adaptation to renal sodium loss has been described and localized in the distal tubule in experimental models of GS but not in humans with GS. DESIGN, SETTING, PARTICIPANT...

Type 2 diabetes causes structural and functional changes in the myocardium, which is called cardiomyopathy. Diabetic cardiomyopathy (DCM) is a distinct primary disorder process, independent of coronary artery disease, which leads to heart failure in diabetic patients. Also, DCM is a multifaceted disorder that is one of the leading causes of death in elderly and postmenopausal women. Menopause i...

tracheomegaly or tracheobronchomegaly is a rare syndrome which is characterized by dramatic dilatation of the trachea and the major bronchi. this syndorme is usually associated with chronic respiratory infection and airway obstruction. in this paper, a case with tracheomegaly and bronchiectasis was scrutinized.

conclusions the castings fabricated from the ringless technique with non-precious alloy are acceptable. this investing system is useable for the fabrication of fixed restorations. results after statistical evaluation, the following results were obtained: the mean vertical margin discrepancy for conventional investing was 156.72 ± 64.67µ; for the ringless technique it was 117.3 ± 26.77µ; and for...

Cardiovascular disease is a leading cause of death in both humans and dogs. Dilated cardiomyopathy (DCM) accounts for a large number of these cases, reported to be the third most common form of cardiac disease in humans and the second most common in dogs. In human studies of DCM there are more than 50 genetic loci associated with the disease. Despite canine DCM having similar disease progressio...

The angiographic appearance of the coronary arteries during successful thrombolysis with urokinase was determined in 35 patients with acute myocardial infarction. The lysing process passed through several phases: (a) total coronary occlusion with a convex or irregular distal margin (phase 0); (b) increasing patency of the lumen (phase 1); (c) re-establishment of flow but with intraluminal filli...

To explain the effect of tip leakage flow on performance an axial-flow transonic compressor, compressors with different rotor clearances were studied numerically. The results show that as clearance increases, intensity is increased, shock wave position moved backward, and interaction between vortex intensified, while boundary layer weakened. Most all, stall mechanisms varying are different. mai...
