Reexamining Different Factors of the Resonance-Enhanced High-Order Harmonic Generation in Atomic and Nanoparticle Laser-Induced Tin Plasmas
2021
We reexamine the resonance enhancement of a single harmonic emission during the propagation of ultrafast pulses through atomic and nanoparticle tin-containing laser-induced plasma (LIP). We compare the single atomic Sn and Sn nanoparticle plasmas to demonstrate a distinction in the enhancement factor of the single harmonic in the case of fixed and tunable near-infrared pulses. The analysis of the dynamics of Sn LIP shows the range of optimal delays between heating and driving pulses (130–180 ns), at which the maximal harmonic yield can be achieved. The enhancements of the 17th and 18th harmonics of 806 nm pulses were analyzed in the case of single-color and two-color pumps of LIP, showing u…
Leptin plasma levels in patients undergoing prostate biopsy. a preliminary study in 50 patients
2013
Introduction/Aim: To reduce the number of negative prostate biopsies and to detect clinical significant prostate tumors in patients with elevated serum PSA represent major challenges in urological oncology. Prostate tumors diagnosed in patients with elevated Body Mass Index (BMI) show higher Gleason score and more aggressive biological behavior than those diagnosed in normal population (1). Elevated plasma levels of leptin and other adipose tissue derived factors (adipokines), are evident in obese men (2). Many studies have investigated the role of leptin as a putative molecular mediator between obesity and prostate cancer with contradictory results. Also in normal or overweight (BMI <30) m…
