High-resolution MR cisternography performed with 3D fast asymmetric spin-echo imaging (3D fast spin-echo with an ultra-long echo train length and asymmetric Fourier imaging) was optimized in a 0.35-T open MR imaging unit. The 0.35- and 1.5-T images of the two volunteers and three patients with acoustic schwannomas were then compared. The optimal parameters for images obtained by 3D fast asymmet...

PURPOSE To investigate quantitatively the effect of elevated intraocular pressure (IOP) on the microvasculature of the optic nerve with and without topical treatment with two hypotensive drugs, timolol and latanoprost. METHODS Three groups of rats underwent cauterization of three episcleral veins to produce elevated IOP in the right eye. Two of these groups were treated with timolol or latano...

We study statistical tests of uniformity based on the Lp-distances between the m nearest pairs of points, for n points generated uniformly over the k-dimensional unit hypercube or unit torus. The number of distinct pairs at distance no more than t, for t Ä 0, is a stochastic process whose initial part, after an appropriate transformation and as n 3 `, is asymptotically a Poisson process with un...

1. Tamm-Horsfall (T-H) glycoprotein has been measured by a specific radioimmunoassay method in the urine of patients with chronic renal failure, cadmium nephropathy and Lignac-Fanconi syndrome, and in renal and bladder calculi. 2. Total T-H glycoprotein excretion/24 h was markedly reduced in patients with chronic renal failure compared with normals. A highly significant correlation was observed...

Abstract Introduction Holmium laser enucleation of the prostate (HoLEP) is a minimally invasive procedure for management Benign Prostatic Hyperplasia and Bladder Outlet Obstruction. The European Associations Urologists (EAU) recommend HoLEP should be offered to patients with prostates measuring >30cc or who are anticoagulated Aim To review outcomes one-unit procedures. Comparing first th...
