Unabsorbed pump light in passively Q-switched microlasers leads to suboptimal pulse generation by bleaching the saturable absorber. This mechanism increases the effective unsaturated transmission of the absorber, which leads to a change in the system dynamics that results in increased pulse durations and decreased pulse energies. We report experimental evidence of pump-induced bleaching of the ...

Background: Pulse therapy is a type of systemic management in which large amounts of medications are administered to patients in short time and intervals (e.g. weekly) to get the stronger effects of medication sooner and avoid long term use of them. Objective: To determine how therapy-resistant dermatology diseases respond to oral minipulse steroids . Methods: Articles with Mesh terms "pulse th...

Introduction: The authors have carried out a retrospective analysis of data from 26 patients with developing vitiligo who were treated with oral mini-pulse of dexamethasone. Clinical response and side effects were evaluated at monthly intervals. Of the 26 patients included in the study, 12 (46.2%) presented a repigmentation of lesions, 11 (42.3%) stabilized, and 3 (11.5%) experienced a worsenin...

maintaining quality and longevity of cut flowers is one of the critical issues in the floriculture industry, especially in cut flowers; and one of the most important problems in chrysanthemum, as one of the most popular cut flowers. therefore, an experiment was conducted based on completely randomized design as pulse treatment with the three factors: tea extracts with 4 levels (5, 10, 20, and 4...

SIR, in Wegener’s granulomatosis (WG) standard therapy with cyclophosphamide (CYC) is limited by treatment-associated shortand long-term morbidity and mortality as well as insufficient response in about 10% of all cases [1]. Several therapeutic regimes have been used for refractory disease with varied results, including monoclonal antibodies to TNF[2] and different surface markers of T-cells (C...

PURPOSE OF REVIEW Recent advances in pulse oximetry have made it possible to noninvasively measure total hemoglobin, as well as the two most common dyshemoglobins. This review will trace the development and clinical application of multiwavelength pulse oximetry. RECENT FINDINGS Until now, commercially produced pulse oximeters have utilized two wavelengths of light and could measure only the r...

diabetic ketoacidosis (dka) is characterized by excessive production of organic acids leading to a low blood ph. rarely, because of other complicating factors blood ph may be in the alkalemic range and the term diabetic ketoalkalosis has been coined to describe this condition. so far, less than 30 such cases have been reported in the literature. we report a 34-year-old woman who received methyl...

OBJECTIVE To compare the efficacy and cognitive side effects of high-dose unilateral brief pulse electroconvulsive therapy (ECT) with those of high-dose unilateral ultrabrief pulse ECT in the treatment of major depression. METHOD From April 2007 until March 2011, we conducted a prospective, double-blind, randomized multicenter trial in 3 tertiary psychiatric hospitals. All patients with a dep...
