Although airway patency is partially maintained by parenchymal tethering, this structural support is often ignored in many discussions of asthma. However, agonists that induce smooth muscle contraction also stiffen the parenchyma, so such parenchymal stiffening may serve as a defense mechanism to prevent airway narrowing or closure. To quantify this effect, specifically how changes in parenchym...

BACKGROUND Breast augmentation by cell-assisted lipotransfer (CAL) may achieve a more natural breast contour than silicone implants. Moreover, certain complications associated with these prosthetic devices can be avoided with CAL. Few prospective studies of CAL have been performed to examine long-term volume changes, effects on breast parenchymal tissue, and the effect of stromal vascular fract...

the correlation of vesicoureteral reflux (vur), urinary tract infection (uti) and renal scarring is well known. several risk factors for renal parenchymal lesions have been reported previously. we determine the incidence of renal parenchymal damage and outcome in the siblings of children with primary vur. a total of 96 siblings of patients with vur, were evaluated with direct voiding cystograph...

The uptake of cadmium in vivo into parenchymal and non-parenchymal (sinusoidal) cells of the liver was studied by a cell-separation technique. Liver parenchymal cells accumulate cadmium more readily than do non-parenchymal cells and synthesize metallothionein. It is proposed that cadmium uptake and metabolism from injected CdCl2, is restricted almost exclusively to the liver parenchymal cells.

Studies were made of the effects of diamphenethide-amine on glucose transport, glycogen breakdown, adenine nucleotides, metabolites and excretory products in both parenchymal and bile duct flukes in vitro and in bile duct flukes in vivo. The most consistent and pronounced effect observed was an elevation of malate levels. There appeared to be no differences between responses of parenchymal and ...

Cerebral venous thrombosis is a relatively uncommon but serious neurologic disorder that is potentially reversible with prompt diagnosis and appropriate medical care. Because the possible causal factors and clinical manifestations of this disorder are many and varied, imaging plays a primary role in the diagnosis. Magnetic resonance (MR) imaging, un-enhanced computed tomography (CT), unenhanced...

INTRODUCTION This study aimed to evaluate parenchymal and functional lung changes following stereotactic body radiotherapy (SBRT) for early-stage non-small cell lung cancer (NSCLC) patients and to correlate radiological and functional findings with patient and treatment characteristics as well as survival. MATERIALS AND METHODS Seventy patients with early-stage NSCLC treated with SBRT from 20...

Biliary lipids, faecal steroids, and serum bile acids were studied in patients with chronic active hepatitis and primary biliary cirrhosis. The results were correlated with excretory and parenchymal liver function tests and with the presence or absence of orcein-positive copper-protein complexes in histological liver specimens. In general, faecal bile acids, but not neutral and total sterols, c...
