Photoselective vaporisation of the prostate (PVP) is an established treatment option for bladder outlet obstruction (BOO). PVP has demonstrated durable clinical efficacy equivalent to other endoscopic procedures at 5 years [1]. Furthermore, PVP has demonstrated superior haemostatic properties compared with other endoscopic treatments for Benign Prostatic Hyperplasia (BPH) [2]. Despite this many...

In the pursuit of more efficient gas turbine engines, components are required to operate for longer times at elevated temperatures. This increased time in service, together with a complex loading regime, can expose material environmental attack. work has demonstrated that interaction stress, NaCl and sulphur-containing environment is critical cause crack initiation early stages exposure acceler...

Resonance Ionization Spectroscopy (RIS) technique is an ultrasensitive method of detection of atoms and molecules. Application of RIS to material analysis requires an atomization step which is based in our set-up on ion beam sputtering. We present a review of the analytical studies we have performed demonstrating the very attractive potentialities of this method. RIS can be also used to study t...

The advantages offered by lasers compared to older technologies for endoscopic surgery for symptomatic benign prostate hyperplasia (BPH) are reviewed. Laser treatments for the endoscopic management of patients with bladder outlet obstruction (BOO) resulting from BPH can be divided into three basic techniques. These techniques are vaporisation (removal of tissue), resection of tissue (excision o...

The application of programmed temperature vaporisation (PTV) in capillary gas chromatographic analysis is reviewed. The development of the different strategies as well as the state of the art are described. As the analytes are normally enriched in the PTV insert, the quoted papers are subdivided depending on whether the enrichment was carried out from organic solvents, from water or from gaseou...

Aspects of the use of filter paper discs in collecting tear samples for lysozyme tests were studied by serial weighings of bijoux bottles and tear-moistened discs. Blotted discs carried from 1.9 to 3.6 mg tears, but for practical purposes no deposit was left in the bottle. Unblotted discs carried a greater quantity of tear fluid, but the majority deposited a proportion of this in the bottle, an...

Architectural design and design decisions are the key components of architectural knowledge. However, concerns, rationales, and risks should be also captured to prevent knowledge vaporization. So, how to deal with architectural knowledge in incremental knowledge refinement? We believe that usage of the knowledge repository system can support architecture evolution. In this paper, a model of kno...

the aim of this study was to evaluate the effect of replacing progesterone injections by progesterone vaginal inserts on productive and reproductive parameters of lactating cows with reproductive problems after prolonged periods of heat stress. fifteen holstein cows were randomly assigned to one of three treatments: 1) treated with two progesterone vaginal inserts (p4-ins); 2) treated with prog...

INTRODUCTION Pseudodiverticulum of the urinary bladder is mostly a complication of subvesical obstruction (SO). The gold standard of treatment was open diverticulectomy with adenectomy. A more contemporary resolution is endoscopic, in two steps: the first transurethral resection of the prostate (TURP), the second laparoscopic diverticulectomy (LD). AIM To present a one-session procedure - pho...
