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. "
01/01/2010 - "The aim of this study was to investigate the effectiveness of 850-nm gallium arsenide aluminum (Ga-As-Al) laser therapy on pain, range of motion and disability in subacromial impingement syndrome. "

01/01/2014 - "The Global Acne Assessment Score (GAAS), the number lesions and side-effects were documented at base line and weeks 4, 8 and 12. "
01/01/2014 - "Treatment outcome was evaluated using physician-scored Global Acne Assessment Scale (GAAS) and patient-reported facial skin condition. "
02/01/2008 - "In the pivotal studies, success based on achieving a Global Acne Assessment Score (GAAS) of 0 (none) or 1 (minimal) at week 12 was significantly greater for the dapsone gel-treated adolescent participants (40.1%; 232/578) compared with the vehicle gel-treated adolescent participants (28.2%; 154/547) (P<.001). "

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. "

12/01/1988 - "A histopathological study of the initial healing of extraction wounds following low-energy laser irradiation, using a gallium-arsenide semi-conductor laser, was carried out in rats. "
02/01/2013 - "Effects of low-level laser therapy (GaAs) in an animal model of muscular damage induced by trauma."
09/18/2008 - "The treatment was carried out by means of laser rays from an aluminum-gallium arsenide diode semiconductor with 9mW applied every other day (total dose=4J/cm2) on the borders of the wound. "
09/01/1994 - "1. Lectins labeled with colloidal gold particles were used for the ultrastructural evaluation of the biological effects of GaAs softlaser irradiation on the healing of dog tendon wounds. "
07/01/1993 - "The impact of various types of low-intensive lasers (He-Ne, copper vapour, ultraviolet, infrared, infrared gallium arsenide) on healing of a wound made by CO2 laser at an output power of 25 W was studied in an experiment on 120 albino Wistar rats. "

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. "
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."
