OBJECTIVE: Photovaporization of prostate (PVP) is a newer surgical modality of benign prostatic hyperplasia (BPH) which is gaining importance recently. There are a few randomized controlled trials that showed safety and efficacy of PVP in comparison with transurethral resection of prostate (TURP) with limited follow-up period (<2 years). Here, we are presenting a comparative study performed on potassium titanyl phosphate (KTP) PVP laser versus TURP for the treatment of BPH with long-term follow-up period...

Barbara Hachuła
The influence of hydrogen-bonding interactions in the solid phase on the IR spectroscopic pattern of the νOH band of nonsteroidal anti-inflammatory drugs (NSAIDs) was studied experimentally by IR spectroscopy with the use of polarized light at two temperatures (293K and 77K) and in isotopic dilution. The neat and deuterated crystals of (S)-naproxen ((S)-NPX), (R)-flurbiprofen ((R)-FBP), (RS)-flurbiprofen ((RS)-FBP) and (RS)-ketoprofen ((RS)-KTP) were obtained by melt crystallization between the two squeezed CaF2 plates...

Two new barium gold iodates, namely, BaAu(IO3)5 and HBa4Au(IO3)12, have been prepared. BaAu(IO3)5 crystallizes in the polar space group Pca21, whereas HBa4Au(IO3)12 crystallizes in the centrosymmetric space group P21/c. BaAu(IO3)5 consists of unique polar [Au(IO3)4](-) anions whose four iodate groups are located at both sides of the AuO4 plane and the polarity points in the [001̅] direction. BaAu(IO3)5 displays strong second-harmonic-generation (SHG) effects about 0.6KTiOPO4 (KTP) and is phase-matchable. Thermal properties, optical spectra analyses, and theoretical calculations are also reported...

Mid-infrared (MIR) nonlinear optical crystals of LiInSe<sub>2</sub> (LISe) were grown by a modified Bridgman technique on a (001)-seed. A 7-12 μm widely tunable picosecond (ps) MIR optical parametric amplifier (OPA) based on a LISe crystal was demonstrated for the first time, to the best of our knowledge. The MIR OPA was pumped by a 30 ps 1064 nm Nd:YAG laser and injected by a KTiOPO<sub>4</sub> (KTP)-based widely tunable near-infrared seed. The idler operating at 7.5 μm with the highest pulse energy of 170 μJ was obtained under a pump energy of 14 mJ...

We investigated the subjective, long-term, patient-reported symptom control after endoscopic potassium titanyl phosphate (KTP) laser reduction of the inferior turbinates. Symptoms were listed preoperatively and patients were asked, via telephone interview, the status of their symptoms. Chi-square analysis was used to assess statistical significance of the surgical intervention. Thirty-six patients (male:female ratio: 5:4) aged 13 to 80 years (mean: 37.2) were available for follow-up. The mean follow-up time was 68...

Neuropeptide kyotorphin (KTP) is a potent analgesic if administered directly into the brain. In contrast, KTP-amide (KTP-NH2) is analgesic, neuroprotective, and anti-inflammatory following systemic administration, albeit its mechanism of action is unknown. The aim of this study was to shed light on the mechanism of action of KTP-NH2 at the molecular level. KTP-NH2 does not inhibit the enkephalinases angiotensin-converting-enzyme and dipeptidyl-peptidase 3. Intravital microscopy showed that KTP-NH2 decreased the number of rolling leukocytes in a mouse model of inflammation induced by lipopolysaccharide (LPS)...

BACKGROUND: Indications for laser therapy for slow-flow vascular malformations in the oral and maxillofacial regions have not been clearly documented. The authors aimed to estimate the frequency of resolution of slow-flow vascular malformations and to identify risk and prognostic factors associated with resolution in potassium titanyl phosphate (KTP) laser treatment. METHODS: This study was designed as a prospective cohort study. Patients who had diagnosed slow-flow vascular malformations were continuously assigned to receive KTP laser therapy...

The spin-polarized second harmonic generation (SHG) of the recently synthesized CaCoSO single crystal is performed based on the calculated electronic band structure. The calculation reveals that the spin-up (↑) channel of CaCoSO possesses a direct energy gap (Γ(v)-Γ(c)) of about 2.187 eV, 1.187 eV (K(v)-K(c)) for the spin-down (↓) channel and an indirect gap (Γ(v)-K(c)) of about 0.4 eV for the spin-polarized CaCoSO single crystal. The linear optical properties obtained reveal that the recently synthesized crystal exhibits considerable anisotropy with negative uniaxial anisotropy and birefringence favor to enhance the SHG...

OBJECTIVES/HYPOTHESIS: Cranial nerve transection during head and neck surgery is conventionally repaired with microsuture. Previous studies have demonstrated recovery with laser nerve welding (LNW), a novel alternative to microsuture. LNW has been reported to have poorer tensile strength, however. Laser-activated chitosan, an adhesive biopolymer, may promote nerve recovery while enhancing the tensile strength of the repair. Using a rat posterior tibial nerve injury model, we compared four different methods of nerve repair in this pilot study...

The low-temperature modification of Sr3(O3C3N3)2 was prepared and assigned as α-SCY after the high-temperature phase (now called β-SCY) and its frequency-doubling properties were reported recently. The crystal structure of α-SCY was solved and refined by single-crystal X-ray diffraction. Both modifications of SCY crystallize in noncentrosymmetric space groups, with the low-temperature phase (α-SCY) adopting the lower symmetry structure (Cc). Atomic positions in α-SCY (Cc) reveal only small deviations in comparison to those in the structure of β-SCY (R3c)...

Two-dimensional (2D) materials, especially transition-metal dichalcogenides, such as molybdenum disulfide (MoS<sub>2</sub>) and tungsten disulfide (WS<sub>2</sub>), have attracted great interests due to their exceptional optical properties as saturable absorbers in laser systems. In this work, at first, we presented a diode-pumped passively Q-switched laser with MoS<sub>2</sub> saturable absorber (MoS<sub>2</sub>-SA). At an incident pump power of 6.54 W, a maximum output power of 1...

We demonstrate a monolithic frequency converter incorporating up to four tuning degrees of freedom, three temperature and one strain, allowing resonance of pump and generated wavelengths simultaneous with optimal phase-matching. With a Rb-doped periodically-poled potassium titanyl phosphate (KTP) implementation, we demonstrate efficient continuous-wave second harmonic generation from 795 to 397, with low-power efficiency of 72% and high-power slope efficiency of 4.5%. The measured performance shows good agreement with theoretical modeling of the device...

INTRODUCTION: Open prostatectomy (OP) and transurethral resection of the prostate (TURP) have traditionally been the most common surgical approaches for the treatment of benign prostatic hyperplasia causing bladder outlet obstruction and have certainly passed the test of time. In time, many endoscopic surgical procedures have been described as an alternative mini-invasive treatment. Holmium laser enucleation (HoLEP) guaranteed functional outcomes similar to OP and TURP with lower peri-operative complication rates for any prostate size...

Laser therapies have been shown to provide symptom improvement in patients with erythema and telangiectasia of rosacea; however, they are associated with side effects such as erythema. Combinatorial treatment with pharmacological agents and laser have demonstrated better efficacy, fewer side effects and continued long-term remission compared with monotherapies. A case of moderate facial erythema that responded well to combination treatment with brimonidine 3 mg/g gel and a treatment course of potassium-titanyl phosphate (KTP) laser therapy is presented, showing a reduction from baseline, maintained after final laser session, by applying brimonidine 3 mg/g gel daily...

The first metal iodate fluoride, Bi(IO3 )F2 , with a strong second harmonic generation (SHG) effect has been prepared. Bi(IO3 )F2 crystallizes in the polar space group C2 and features a three-dimensional [BiF2 ](+) cationic framework with IO3 groups capping the inner walls of the one-dimensional tunnels. This [BiF2 ](+) cationic framework acts as a template for the assembly of the polar IO3 units in a favorable superposed fashion, which leads to the polar structure of the material. Bi(IO3 )F2 displays a rather wide transmittance window (0...

Non-steroidal anti-inflammatory drugs (NSAIDs) are the most frequently used group of pharmaceuticals. The high consumption and the uncontrolled disposal of unused drugs into municipal waste or their deposit in landfills can result in an increased concentration of these compounds in soils. Moreover, these drugs can affect the microbial activity. However, there is a lack of knowledge about these effects or it is very limited. Therefore, the objective of this study was to compare the impact of selected commercially available NSAIDs, i...

Sino-nasal smooth muscle tumours of uncertain malignant potential (SMTUMP) are very rare neoplasms of mesenchymal origin with features in between a benign leiomyoma and a leiomyosarcoma. We report a rare case of SMTUMP in a 44-year-old woman, who presented with vague symptoms of pharyngitis. Nasal endoscopy revealed a smooth mass in left nasal cavity. Contrast-enhanced CT and MRI scans showed features likely to be inverted papilloma or olfactory neuroblastoma or meningioma. Excision was planned and intraoperatively, frozen section revealed a probable spindle cell lesion...
