OBJECTIVE The purpose of the current study was to evaluate the differences in hearing results and complications between the conventional technique (CT) and potassium titanyl phosphate laser (KTP) laser-assisted stapes surgery that does not involve the manipulation of the foot plate. METHODS Ninety-eight ears with conductive or mixed hearing loss due to otosclerosis were operated on by using t...

Background: Irritative symptoms including prolonged urgency and dysuria after GreenLight laser photoselective vaporization (PVP) of benign prostatic hyperplasia (BPH) are common complication. We aimed to compare the incidence of postoperative irritative symptoms of GreenLight XPS (GL-XPS) 180W laser system with GreenLight KTP (GL-KTP) 80W laser system for the treatment of BPH and evaluate the r...

BACKGROUND Bleaching of traumatized discolored teeth is considered an important issue in esthetic dentistry. Various methods have been introduced for bleaching, some of which may have adverse effects on soft or hard tissues of the tooth. OBJECTIVES The objective of the study was to evaluate the effects of KTP laser bleaching on enamel of traumatized teeth. MATERIALS AND METHODS A square of ...

In Alzheimer's disease (AD), besides the characteristic deterioration of memory, studies also point to a higher pain tolerance in spite of sensibility preservation. A change in the normal tau protein phosphorylation is also characteristic of AD, which contributes to the pathogenesis of the disease and is useful in early diagnosis. Kyotorphin (KTP) is an endogenous analgesic dipeptide (Tyr-Arg) ...

CONTEXT AND OBJECTIVE Lasers are widely used in treating symptomatic benign prostatic hyperplasia. In current practice, potassium titanyl phosphate (KTP) lasers are the most common type of laser systems used. The aim here was to evaluate the rapid effect of high-power laser systems after application of hypericin. DESIGN AND SETTING Experimental animal study conducted in the Department of Urol...

This paper reflects on a Knowledge Transfer Partnership (KTP) at Construction Youth Trust (the Trust) with London South Bank University (LSBU) that aims to provide the Trust with a comprehensive and internal process that will result in Social Return on Investment (SROI) being embedded within the organisation. The aims of this paper are twofold, firstly to examine the development and growth of K...

Femto-second laser writing was used to fabricate waveguides in KTP with losses below 0.8 dB/cm. They were used for efficient broad bandwidth, Type II frequency doubling of cw Ti-sapphire laser radiation at 1080.4 nm. Keywords; laser written waveguides, low loss, broad bandwidth, KTP, type II frequency doubling

Absolute magnitudes of the effective nonlinearity, deff, were measured for seven KTP and six BBO crystals. The d(eff), were derived from the parametric gain of an 800-nm signal wave in the sample crystals when they were pumped by the frequency-doubled, spatially filtered light from an injectionseeded, Q-switched Nd:YAG laser. The KTP crystals, all type II phase matched with propagation in the X...

Kudingcha is a traditional Chinese tea, and insect tea is a special drink produced by the metabolism of insect larvae using the raw Kuding tea. Insect tea polyphenols (ITP) and its raw tea (Kuding tea) polyphenols (KTP) are high-purity polyphenols extracted by centrifuge precipitation. The present study was designed to compare the antioxidative effects of insect tea polyphenols (ITP) and its ra...
