to the degree of coronary narrowing, 47 consecutive chest pain patients were studied without premedication by analysing selective coronary angiograms before and after glyceryl trinitrate. Proximal coronary diameters were measured in superimposed frames with callipers. Lumen diameter increased after glyceryl trinitrate 15 ± 2 per cent in the left main, 18 ± 2 per cent in the left anterior descen...
Lumbar epidural blockade has been used in 317 subjects to compare the analgesic properties of the hydrochloride salts of lignocaine and prilocaine in 2 per cent and 3 per cent concentrations, with and without 1/200,000 adrenaline. Prilocaine has a slower onset and spread of analgesia than lignocaine. Duration of action and intensity of motor blockade is greater with plain prilocaine than with p...
This paper presents a matrix-analytic solution for second-order Markov fluid models (also known as Markov-modulated Brownian motion) with level-dependent behavior. A set of thresholds is given, that divide the fluid buffer into homogeneous regimes. The generator matrix of the background Markov chain, the fluid rates (drifts) and the variances can be regime dependent. The model allows the mixing...

BACKGROUND Numerous published studies have explored associations between anaemia and adverse outcomes after surgery. However, there are no evidence syntheses describing the impact of preoperative anaemia on postoperative outcomes. METHODS A systematic review and meta-analysis of observational studies exploring associations between preoperative anaemia and postoperative outcomes was performed....
BACKGROUND Minimal access surgery for gastrointestinal cancer has short-term benefits but is associated with a proficiency-gain curve. The aim of this study was to define national proficiency-gain curves for minimal access colorectal and oesophagogastric surgery, and to determine the impact on clinical outcomes. METHODS All adult patients undergoing minimal access oesophageal, colonic and rec...
Glomerular diseases are the leading cause of ESKD worldwide. IgA nephropathy (IgAN), focal segmental glomerulosclerosis (FSGS), Alport syndrome (AS), and diabetic kidney disease (DKD) important glomerular characterized by proteinuria, a predictor progression ESKD. Endothelin A (ETA) receptor activation drives inflammation, fibrosis. Therefore, atrasentan, potent selective ETA antagonist, has po...

Up to not so long ago, Loop-Free Alternates (LFA) was the only viable option for providing fast protection in pure IP and MPLS/LDP networks. Unfortunately, LFA cannot provide protection for all possible failure cases in general. Recently, the IETF has initiated the Remote Loop-Free Alternates (rLFA) technique as a simple extension to LFA, to boost the fraction of failure cases covered by fast p...
