Mitigation of photoreceptors abnormalities after low-level laser therapy and chia seeds supplementation in experimental diabetic retinopathy.

Background: This study aimed to assess the effect of low-level laser therapy (LLLT) and chia seeds on the mitigation of photoreceptors abnormalities in experimental diabetic retinopathy (DR).

Materials And Methods: A total of 65 female Wistar rats, 5 rats were served as a control group and 60 rats were injected intraperitoneally with one dose of 55 mg/kg of streptozotocin (STZ) to induce DR after 6-8 weeks. The rats were divided into ( = 20 rats each): (a) DR group: did not receive any treatment, (b) DR+ LLLT group was exposed to 670-nm LLLT for 6 weeks (two sessions/week), and (c) DR+ LLLT+ chia seed group, in which rats were exposed to LLLT and administrated with 250 mg/kg/day of chia seeds flour for 2 weeks before STZ injection and continued to the end of the experiment.

Low-Level Laser Therapy with 670 nm Alleviates Diabetic Retinopathy in an Experimental Model.

Purpose: To evaluate the effects of low-level laser therapy (LLLT) on the retina with diabetic retinopathy (DR).

Methods: Eight Wistar rats were used as a control group, and 64 rats were injected intraperitoneally with 55 mg/kg of streptozotocin to induce diabetes and served as a diabetic group. After the establishment of the DR, the rats were separated into (a) 32 rats with DR; did not receive any treatment, (b) 32 rats with DR were exposed to 670 nm LLLT for 6 successive weeks (2 sessions/week).

Innovative application of helium-neon laser: enhancing the germination of Adansonia digitata and evaluating the hepatoprotective activities in mice.

The laser pretreatment of seed is drawing pronounced attention from the scientific community for its positive impact in boosting germination, seedling , and growth of plants. In this study, the laser pretreatment of Adansonia digitata (A. digitata) seeds was evaluated.

The Synergistic Cytotoxic Effect of Laser-Irradiated Gold Nanoparticles and Sorafenib Against the Growth of a Human Hepatocellular Carcinoma Cell Line.

Gold nanoparticles are the most promising candidate in cancer treatment due to their physiochemical properties
and increased use in photothermal therapy (PTT). In the present study, spherical gold nanoparticles (AuNPs) were
synthesized using citrate reduction method. The particles were then characterized using UV-VIS spectroscopy and
transmission electron microscope.

Has the time come to include low-level laser photobiomodulation as an adjuvant therapy in the treatment of impaired endometrial receptivity?

Low-level laser therapy (LLLT) has been used in photobiomodulation to promote healing, regenerate, and restore tissue function. Women with persistent thin endometrium were assumed to encounter diminished activity in the regenerative and functional capacity of their endometrium. The aim of this study was to examine the ability of LLLT in 635 nm wavelength to enhance the proliferation and gene expression of in vitro cultured endometrial cells.

A novel management of streptococcal pharyngotonsillar infections by laser-activated silver nanoparticles and methylene blue conjugate, in vitro study.

Introduction: Species of Streptococcus are classified based on their hemolytic properties into alpha and beta types. And, since antimicrobial drug resistance is an increasingly problematic issue, the efforts to develop modalities that would overcome this obstacle and avoid antibiotic side effects is an ongoing challenge.

Methods And Materials: 20 patients from both sexes were selected.

An exploration of experts' perceptions on the use of interprofessional education to support collaborative practice in the care of community-living older adults.

Globally, as older adults are living longer and with more chronic conditions, there is a need to support their ability to age optimally in their homes and communities. Community-based interprofessional teams working closely with these older adults, their families, and informal caregivers will be instrumental in achieving this goal. Interprofessional education (IPE) is the means through which these teams can develop expertise in collaboratively working together with older adults.

Photodecomposition, photomutagenicity and photocytotoxicity of retinyl palmitate under He-Ne laser photoirradiation and its effects on photodynamic therapy of cancer cells in vitro.

Objective: Our aim was to study photodecomposition, photomutagenicity and cytotoxicity of retinyl palmitate (RP), a principal storage form of vitamin A in humans and animals, under He-Ne laser photoirradiation. Moreover, the effect of different concentrations and timing protocol of antioxidants on photodynamic therapy (PDT) is contradictory, so the effect of RP (as antioxidant) on the PDT cytotoxicity was studied.

Methods: Photomutagenicity was tested by Ames test.

Photodynamic antibacterial enhanced effect of methylene blue-gold nanoparticles conjugate on Staphylococcal aureus isolated from impetigo lesions in vitro study.

Background: Staphylococcal aureus is the most common organism which has been encountered in impetigo infection. Gold nanoparticles can be used as a tool to deliver antimicrobials or to enhance photodynamic destruction of bacteria.

Objective: To evaluate the photodynamic effect of methylene blue gold nanoparticles (MB-gold nanoparticles conjugate) on S.
