Diode and DPSS lasers emitting a variety of wavelengths are now commonly incorporated into flow cytometers, greatly increasing our capacity to excite a wide variety of fluorochromes. Until recently, however, virtually no practical technology existed for generating yellow or orange laser light for flow cytometry that was compatible with smaller instrumentation. In this study, we evaluate several...
Purpose: Low level laser therapy is suggested as a new therapeutic method in diabetic wound healing. This survey aimed to evaluate the effects of low level laser on human fibroblasts cultured in high glucose cultures. Materials and Methods: The human skin fibroblasts were cultured under standard condition. The cells were cultured in high glucose culture medium (15mM/L) for a week and two weeks ...
background: laser-tissue interaction on low-level laser therapy (lllt) has widespread medical applications (e.g., improved wound healing). the tensile strength of radiated tissue by lllt is known to be increased mainly because of cross collagen bands developed after radiation. objective: in this work, we studied the instantaneous effect of radiation of polarized laser beam on the viscoelastic t...
vascular lesions rise from abnormalities in blood vessels or endothelial proliferation . capillary hemangiomas are formed by small capillaries surrounded by a layer of endothelial cells in a connective tissue stroma . various treatments are used for these conditions like excisional surgery , sclerotherapy, and recently laser irradiation. in this case study, we report successful treatment of int...
Fluorescence spectra of dentine and enamel illuminated with laser light of wavelengths of 337, 488, 515 and 633 nm respectively were recorded. The fluorescence obtained by illumination with UV laser light at 337 nm had a peak at about 400 nm in dentine as well as enamel. Compared to intact enamel the fluorescence from enamel with initial carious lesions was of lower intensity and had a slight r...
introduction: low-level laser therapy (lllt) is shown effective in healing diabetic foot ulcer when combined with conventional therapy. since; diabetes mellitus is a leading cause of impaired wound healing. the aim of this study is to determine the effect of different diabetic control’s methods on the healing response of diabetic foot ulcer in those patients treated with low level laser therapy...
In this research we measure some of the optical parameters of Barium Titanate crystal (BaTiO3), such as signal beam gain, coupling constant (exponential gain coefficient), change in index refraction and photorefractive sensitivity, which are very significant for optical data storage. In all experiment, two- wave mixing configuration at 632.8 nm (He- Ne laser) were used. Experimental data f...
A new analytical method had been developed to enable high-spatial-resolution (U–Th)/He dating of accessory minerals. It involves the use of a focused ArF excimer to ablate pits in a polished grain surface, with the evolved gases spiked for isotope-dilution measurement of radiogenic He. These data are converted to concentrations by precise measurement of each pit using an optical interferometric...
The patient was a 10-month-old infant with respiratory distress.During clinical examination and radiography we suspected to congenital laryngeal disorder.The infant was examined by direct laryngoscopy under general anesthesia. After laryngoscopy we diagnosed laryngeal ductal cyst and resected by Co2 laser. After several days the symptoms of the patient improved and he left hospital.
