PURPOSE To examine the effect of free insulin-like growth factor (IGF) binding protein-3 (IGFBP-3), independent of the effect of insulin-like growth factors, in modulating retinal vascular permeability. METHODS We assessed the ability of a form of IGFBP-3 that does not bind IGF-1 (IGFBP-3NB), to regulate the blood retinal barrier (BRB) using two distinct experimental mouse models, laser-induc...
Using a laser trap, we have studied the properties of erythrocytes from a sickle cell anemia patient (SCA) after receiving an intravenous blood transfusion, and a normal adult individual carrying normal adult hemoglobin. The hemoglobin type and quantitation assessment was carried out by high performance liquid chromatography (HPLC). We conducted an analysis of the size distributions of the cell...
Introduction: Low-energy helium-neon (He-Ne) laser beam lightis used in combination with sodium hypochlorite (Na2HOCl3) for clinical purposes. Regarding this, the present study aimed to investigate the effect of He-Ne laser (632.8 nm) and sodium hypochlorite on the calf thymus double-stranded deoxyribonucleic acid (ctdsDNA) molecule. Materials and Methods: For the purpose of the study, ctdsDNA...
SUMMARY We have discussed in this article, about usages of Laser (Cortype) In Neurological - Surgery, In the beginning of the article, historical considerations have been written, then specifications of laser light have been noted, including the functions of laser. In this article, types of laser have been matched. In the another part of article, advantages of Co2 . laser have been mentioned,...
Difficult intravenous (IV) access may be a concern encountered by anaesthesiologists in everyday practice. Peripheral venous catheter placement may be difficult, especially at the extremes of age or if the patient is obese, dark skinned, an IV drug abuser, hypotensive [1]. Currently the methods such as ultrasound, laser rod and local hot compress are adopted to deal with the difficulties but th...
Neovascularization after vein stripping is well recognized as a contributory cause of varicose vein recurrence. Treatment is challenging because of segment tortuosity and fibrous web formation. Surgical re-exploration is practiced, but foam sclerotherapy is becoming preferred. We suggest an alternative method using thermoablation with a technique originally intended for treatment of perforator ...
Background and Aim: Diode laser is a great choice for soft tissue surgery. The diode laser is partially absorbed by hard dental tissues, making it safe for soft tissue surgery. This study aimed to compare the tissue thermal changes induced by three types of diode lasers at 810, 940, and 980nm wavelengths. Materials and Methods: In this in-vitro experimental study, using a diode laser device (c...
Background and Aim: Bleaching can improve the color of restorative materials and resolve problems related to discoloration or color mismatch. This study evaluated the effect of in-office bleaching method in conjunction with two different laser wavelengths on color change of two types of glass-ionomer restorative materials (light-cure and self-cure). Materials and Methods: In this experimenta...
Nowadays, Erbium: YAG laser resurfacing of periorbital skin has become a very popular method of wrinkle reduction. Seven patients with Fitzpatrick skin phototypes of II to V were treated with a 2940 nm Erbium: YAG laser system for resurfacing of periorbital wrinkles. Photographic evalution performed before and after treatment. Patients were visited at 1,2,3,5,7,14,30 and 60 days after laser res...
