gallium arsenide (GaAs)

11/01/2016 - "In this study, it is demonstrated that the simultaneous combination of the CO2 wavelength (10600 nm) and GaAs wavelength (1540 nm) reduced the downtime, reduced pain during the treatment, and produced better results on fine wrinkles reduction and almost the same results on pigmentation as seen with 3D analysis by Antera (Miravex)."
01/01/2004 - "Efficacy of 904 nm gallium arsenide low level laser therapy in the management of chronic myofascial pain in the neck: a double-blind and randomize-controlled trial."
09/01/2012 - "As one of physical modalities, gallium-arsenide low-power laser combined with conventional physiotherapy has superiority over routine physiotherapy from the view of decreasing pain and improving the patient's function, but no additional advantages were detected in increasing shoulder joint range of motion in comparison to other physical agents."
06/01/2010 - "The aim of this study was to investigate the efficacy of gallium-arsenide (GaAs) laser therapy, which was performed with the dose regimen recommended by the World Association for Laser Therapy, in relieving pain and improving functional activities in patients with LE. "
02/01/1999 - "The semiconductor or laser diode (GaAs, 904 nm) is the most appropriate choice in pain reduction therapy. "

06/01/2017 - "The studies included patients with 20 to 50 inflammatory and 30 to 100 noninflammatory facial lesions, and a Global Acne Assessment Score (GAAS) of 3 (moderate). "
02/01/2023 - "The GAAS meaning global acne assessment scale did not change after 4-8 weeks of treatment. "
02/01/2023 - "There were 15 females and 5 males in group B: 24.4 ±3.7 years old and weighing 56.4 ±8.46 kg. After 12 weeks, group A shows better global acne assessment scale (GAAS) outcomes than group B than group B. "
06/01/2018 - "An independent rater assessed Global Acne Assessment Score (GAAS) at baseline and at 12 weeks based on photographs. "
02/01/2018 - "Efficacy was evaluated using the Global Acne Assessment Score (GAAS), lesion counts, and Acne Symptom and Impact Scale (ASIS); adverse events (AEs) and tolerability were also assessed. "

01/01/2023 - "Results from this study suggested that GaAs-based spectral mammography could serve as a non-invasive measure for ruling out malignancy of calcifications found in the breast. "
05/01/2013 - "In 2-year inhalation studies, GaAs increased the incidence of lung tumors in female rats, but not in male rats or male and female mice. "
06/01/2010 - "This study, including 361 GAAs and 616 controls without any evidence of tumors, was designed to evaluate the association between the polymorphisms of DNA repair genes XPC Ala499Val (RS#2228000) and Lys939Gln (RS#2228001), XPD Lys751Gln (RS#13181), and XRCC4 Ala247Ser (RS#3734091) and Ser298Asn (RS#1805377), and GAA risk for Guangxi population by means of TaqMan-PCR analysis. "
01/01/2020 - "We found that GaAs-induced abnormal gene expression was mainly related to the cellular response to chemical stimuli, the regulation of signalling, cell differentiation and the cell cycle, which are involved in transcriptional misregulation in cancer, the MAPK signalling pathway, the TGF-β signalling pathway and pulmonary disease-related pathways. "
11/01/1989 - "Treated mice demonstrated a significantly decreased resistance to the B16F10 melanoma with a sevenfold increase in tumor burden at 200 mg/kg. GaAs affects both humoral and cellular immune parameters in mice and impairs the ability of the immune system to protect against B16F10 tumor challenge."

01/01/2022 - "Clinical and functional efficacy of gallium-arsenide super pulsed laser therapy on temporo mandibular joint pain with orofacial myalgia following healed unilateral cervicofacial burn - A randomized trial."
01/01/2022 - "However, clinical studies are lacking in investigating the effects of gallium-arsenide (Ga-As) super pulsed laser therapy on temporomandibular joint pain and orofacial myalgia following healed cervicofacial burn patients. "

01/01/2003 - "A prospective, double-blind, randomized, and controlled trial was conducted in patients with knee osteoarthritis (OA) to evaluate the efficacy of infrared low-power Gallium-Arsenide (Ga-As) laser therapy (LPLT) and compared two different laser therapy regimes. "
