Introduction: In men, several factors cause infertility, among which we can mention damage to sperm due to high temperature. So far, various treatments have been proposed for it, but they have not been highly effective. The current study aimed to evaluate the effect of exosome therapy (EXO) and photobiomodulation therapy (PBMT) on spermatogenesis arrest in male mice after scrotum hyperthermia. Methods: In this experimental study, the animals were divided into four groups: control, scrotal hyperthermia, scrotal hyperthermia+EXO (100 μL/d) (mice were treated for 30 days), scrotal hyperthermia+PBMT (laser of 0...

Introduction: The preference for endovascular techniques in treating varicose veins, particularly in the great saphenous vein (GSV), has increased due to their minimally invasive nature and reduced complications. Post-operative care, especially involving compression therapy, remains crucial to improve outcomes, prevent varicose vein recurrence, and enhance overall recovery. This study aimed to evaluate the efficacy of eccentric compression therapy compared to alternative post-operative care methods following endovenous laser treatment (EVLT) for GSV insufficiency...

Introduction: Endodontic treatment of teeth with periapical lesions presents more clinical difficulty. Various lasers in several methods are used in endodontics, and most of them are utilized as an adjunctive protocol in order to reduce the bacterial load of the root canal system. Improved disinfection plays a crucial role in enhanced and accelerated healing of periapical lesions. This review aims to summarize studies assessing the effect of lasers on periapical lesion healing. Methods: PubMed/MEDLINE, Scopus, Embase, and Web of Science (ISI) online databases were searched, with no publication year or status restriction, for relevant articles on April 2023...

Introduction: Dental hard and soft tissues have been successfully removed by using the Er,Cr:YSGG laser, but there is a controversy about using lasers over conventional tooth surface preparation for bonding aesthetic restoration. Surface roughness and wettability in response to Er,Cr:YSGG laser irradiation are essential properties for restoration longevity. Methods: Fifty-one intact human premolars removed in orthodontic treatment were included in this study and divided into three groups (n=17). The first group (G1) was the control without surface treatment, (G2) was treated with 37% phosphoric acid for 15 seconds, and (G3) was treated with the Er,Cr:YSGG laser using the following parameters: 2 W or 3 W at 20 Hz, 10% air and water ratio using the MZ6 laser tip...

Introduction: Biophoton emission, the spontaneous release of photons from living cells, has emerged as an attractive field of research in the study of biological systems. Scientists have recently discovered that changes in biophoton emission could serve as potential indicators of pathological conditions. This intriguing phenomenon suggests that cells might communicate and interact with each other through the exchange of these faint but significant light signals. Therefore, the present study introduces intercellular relationships with biophoton release to detect normal and abnormal cell functions to further achieve cellular interactions by focusing on cell and cell arrangement in disease conditions...

Introduction: The immune response to laser tattoo removal poses a significant challenge in its management, primarily due to its unpredictable nature, which can range from mild hypersensitivity reactions to severe anaphylaxis. Such responses can potentially hinder the effectiveness of laser tattoo removal procedures. Therefore, gaining a comprehensive understanding of the immune response to tattoo removal using laser techniques is of utmost importance to develop more efficient management strategies. This study aims to address this need by analyzing eight carefully selected articles obtained through a thorough literature review...

Introduction: Photodynamic therapy (PDT) is a combined method of light and light-activated chemicals that are called photosensitizers (PSs). PDT is recommended as a high cure rate method with fewer side effects and a noninvasive tool to treat cancer. This study aimed to evaluate PDT efficacy as a therapeutic method against actinic keratoses in patients via protein-protein interaction (PPI) network analysis by using the gene expression profiles of Gene Expression Omnibus (GEO). Methods: Twenty-one gene expression profiles were extracted from GEO and analyzed by GEO2R to determine the significant differentially expressed genes (DEGs)...
