Comparison of the effects of laser photobiomodulation at wavelength of 660 nm and 808 nm in full-thickness burns in rats: a pre-clinical study.

Third-degree burns are severe thermal injuries that require prolonged recovery periods and are associated with significant sequelae. Photobiomodulation therapy (PBMT) has emerged as a promising approach for treating skin injuries, although parameter selection remains controversial. This study investigated the effects of PBMT using red (wavelength 660 nm) and infrared (wavelength 808 nm) lasers on tissue repair in third-degree burns in rats.

Chitosan-based structures for skin repair: A literature review.

The use of chitosan in technological and biomedical applications has gained significant relevance due to its functional properties. Among its biological activities, its hemostatic, analgesic, antibacterial and anti-inflammatory activities make this natural biopolymer one of the most promising in the development of structures for skin repair. Its application and effects can be optimized by exploring efficient structuring techniques.

Educational Apps and Dog Behavioural Problem Prevention: Associations Between the Zigzag Dog-Training App and Behavioural Problems.

Behavioural problems in dogs are a major welfare concern for both dogs and owners, which can lead to relinquishment or euthanasia. As such, it is important to find ways to minimize the risk of development or severity of problematic behaviour. Such interventions should ideally occur early in the dog's development and need to be widely and easily accessible.

Safety and efficacy of the unilateral, suture-based, dry-closure technique in percutaneous trans-axillary aortic valve implantation.

Background: Transaxillary transcatheter aortic valve implantation (TAx-TAVI) is the most used alternative access when severe iliofemoral disease renders transfemoral access infeasible. Compared to surgical transaxillary access, a true percutaneous approach using vascular closure devices (VCD) has advantages but can be challenging. Herein, we describe the impact of the "unilateral, suture-mediated, dry-closure technique" on vascular safety and efficacy in patients undergoing true percutaneous TAx-TAVI.

Influence of an aquatic resistance progressive exercise and low-level laser therapy on musculoskeletal atrophy: an experimental model of knee osteoarthritis.

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.
