[Purpose] The aim of this study was to evaluate the effect of high-power Nd:YAG laser on and bacterial growth. [Materials and Methods] Seven samples of and seven samples of were prepared in the microbiology lab, one used as a control sample and the remaining six samples used as experimental samples, which were irradiated by a high-power laser (LASERSIX ME, 15W) with a total dose of 500 and 700 J. The primary measure was the semi-qualitative assessment of turbidity and bacterial count; the turbidity was assessed 24 h after laser application. [Results] There was a significant decrease in turbidity in all experimental samples of and after 24 h of high-power laser application for 500 and 700 J and a significant decrease in the colony-forming unit (CFU) value in both types, and there were no significant differences in turbidity and CFU when comparing 500 and 700 J. [Conclusion] A high power Nd:YAG laser was found to be an effective modality for inhibition of and growth.

Article Synopsis
- Melasma is a common, chronic skin condition that mainly affects women, presenting as dark patches on the face and is often perceived as a serious cosmetic issue.
- A survey conducted among 199 dermatologists in Turkiye revealed that the majority of patients with melasma are females between the ages of 30 to 40, with mixed melasma being the most common type.
- The study found that topical treatments, particularly Kligman's formula, are most frequently used, while oral treatments like tranexamic acid are less common, and there's a significant recurrence rate of 41%-60%, suggesting the need for better management strategies.
Anion photoelectron spectroscopy and chemical bonding of ThS2- and ThSO.

Department of Chemistry, Johns Hopkins University, Baltimore, Maryland 21218, USA.
Anion photoelectron spectra of ThSO- and ThS2- were recorded using the third (355 nm) harmonic of an Nd-YAG laser; these provided the measured vertical detachment energies of each anion. The experiments are supported by extensive coupled cluster calculations on ThSO, ThSO-, ThS2, and ThS2-, as well as the oxygen congeners ThO2 and ThO2-. The ab initio calculations, which included complete basis set extrapolations, spin-orbit effects using four-component coupled cluster, and higher-order correlation contributions through CCSDT(Q), yielded an adiabatic electron affinity for ThO2 that was within 0.

Plasma focus devices represent a class of hot and dense plasma sources that serve a dual role in fundamental plasma research and practical applications. These devices allow the observation of various phenomena, including the z-pinch effect, nuclear fusion reactions, plasma filaments, bursts, shocks, jets, X-rays, neutron pulses, ions, and electron beams. In recent years, considerable efforts have been directed toward miniaturizing plasma focus devices, driven by the pursuit of both basic studies and technological advancements.

Article Synopsis
- The study looked at the risks of retinal detachment (RD) after a specific eye surgery called Boston Type 1 Keratoprosthesis (B1KPro) during the first year and beyond.
- They found that 29% of patients experienced RD, with most cases happening within the first year (21%) and fewer later (7%).
- Important risk factors for early RD included low eye pressure (hypotony), previous eye surgeries, and certain eye conditions, while changes in the retina before surgery were linked to later RD.
