AI Article Synopsis
- The study aimed to assess the effectiveness of a 5 mW laser in treating chronic tinnitus through a double-blind, randomized format involving 66 ears from 45 patients.
- Patients received either the active laser treatment or a placebo for one week, with symptoms rated on a five-point scale before and after treatment.
- Results showed significant improvement in loudness, duration, and annoyance of tinnitus in nearly half of those receiving the active laser, while no improvement was noted in the placebo group, indicating the laser's potential effectiveness.
Article Abstract
Objective: To evaluate effectiveness of 5 mW laser irradiation in the treatment of chronic tinnitus.
Study Design: Prospective, randomised, double-blind study.
Methods: This investigation included 66 ears in 45 patients with chronic unilateral or bilateral tinnitus. A 5 mW laser with a wavelength of 650 nm, or placebo laser, was applied transmeatally for 15 minutes, once daily for a week. A questionnaire was administered which asked patients to score their symptoms on a five-point scale, before and two weeks after laser irradiation. A decrease of one scale point, regarding the loudness, duration and degree of annoyance of tinnitus, was accepted to represent an improvement.
Results: The loudness, duration and degree of annoyance of tinnitus were improved, respectively, in up to 48.8, 57.7 and 55.5 per cent of the patients in the active laser group. No significant improvement was observed in the placebo laser group.
Conclusion: Transmeatal, low power (5 mW) laser irradiation was found to be useful for the treatment of chronic tinnitus.

Radiation-Induced Wavelength Shifts in Fiber Bragg Gratings Exposed to Gamma Rays and Neutrons in a Nuclear Reactor.

Soreq NRC, Yavne 81800, Israel.
Fiber Bragg gratings (FBGs) inscribed by UV light and different femtosecond laser techniques (phase mask, point-by-point, and plane-by-plane) were exposed-in several irradiation cycles-to accumulated high doses of gamma rays (up to 124 MGy) and neutron fluence (8.7 × 10/cm) in a research-grade nuclear reactor. The FBG peak wavelengths were measured continuously in order to monitor radiation-induced shifts.

Laser powder bed fusion (LPBF) is an additive manufacturing process that has gained interest for its material fabrication due to multiple advantages, such as the ability to print parts with small feature sizes, good mechanical properties, reduced material waste, etc. However, variations in the key process parameters in LPBF may result in the instantiation of porosity defects and variation in build rate. Particularly, volumetric energy density (VED) is a variable that encapsulates a number of those parameters and represents the amount of energy input from the laser source to the feedstock.

The use of very high energy electron (VHEE) beams, with energies between 50 and 400 MeV, has drawn considerable interest in radiotherapy due to their deep tissue penetration, sharp beam edges, and low sensitivity to tissue density. VHEE beams can be precisely steered with magnetic components, positioning VHEE therapy as a cost-effective option between photon and proton therapies. However, the clinical implementation of VHEE therapy (VHEET) requires advances in several areas: developing compact, stable, and efficient accelerators; creating sophisticated treatment planning software; and establishing clinically validated protocols.

The aim of this study was to evaluate the effectiveness of an aquatic progressive resistance exercise (APRE) and PBM (associated or not) on morphology of skeletal muscle and biochemical markers using an experimental model of knee osteoarthritis (OA). Fifty male Wistar rats were randomly distributed into 5 groups: control group (CG); OA control (OAC); OA submitted to APRE (OAE); OA submitted to PBM (OAL); OA submitted to APRE and PBM (OAEL). Trained rats performed a water-jumping program carrying a load equivalent to 50-80% of their body mass strapped to their chest.

Photothermal therapy (PTT) using thermal and tumor microenvironment-responsive reagents is promising for cancer treatment. This study demonstrates an effective PTT nanodrug consisting of hollow-structured, thermally sensitive polydopamine nanobowls (HPDA NB), molybdenum sulfide (MoS) nanozyme, and tirapazamine (TPZ; a hypoxia-responsive drug), with a structure of HPDA@TPZ/MoS NBs which is hereafter denoted as HPTZMoS NBs. With the Fenton-like activity, the HPTZMoS NBs in the presence of HO catalyze the formation of hydroxyl radicals, providing chemodynamic therapy (CDT) effect and deactivating glutathione.
