introduction: diode laser with wavelengths ranging from 810 to 980 nm in a continuous or pulsed mode was used as a possible instrument for soft tissue surgery in the oral cavity. discussion: diode laser is one of laser systems in which photons are produced by electric current with wavelengths of 810, 940 and 980nm. the application of diode laser in soft tissue oral surgery has been evaluated fr...

background neck reconstruction is considered as one of the most important surgeries in cosmetic and reconstructive surgery. the present study aimed to assess the results of reconstructive surgery of extensive face and neck burning scars using tissue expanders. methods this descriptive prospective study was conducted on 36 patients with extensive burning scars on the neck and face. operation for...

objective: the aim of this study was to evaluate the effect of sucrose on follicular survival rate and the incidence of apoptosis in rat ovarian tissue following vitrification. methods: ovaries of approximately 5-week-old female wistar rats were divided randomly into three groups: control (non-vitrified), vi (ethylene glycol + dimethyl sulfoxide) and vii (eg + dmso + 0.25 mol/lit sucrose). vit...

leaf and root explants from 10 to 20 day– old seedlings of plantago lanceolata, were cultured on ms, msh, nt and b5 basal media with various concentrations of different plant growth regulators. the best callus induction was obtained with 0.4 mgl-1 2,4-d in msh i with 400 callus index. callus growth was significantly stimulated (p=0.05)with 0.8 mgl-1 2,4-d and 0.1 mgl-1 kin in msh ii, with 7...

introduction: the phenomenon of neglected foreign bodies is a significant cause of morbidity in soft tissue injuries and may present to dermatologists as delayed wound healing, localized cellulitis and inflammation, abscess formation, or foreign body sensation. localization and removal of neglected soft tissue foreign bodies (stfbs) is complex due to possible inflammation, indurations, granulat...

abstract gerbera is one of the most demanded plants in commercial cut flowers plants. optimizing the micro-propagation of new cultivars is therefore important. in this research “red explosion” cultivar was used and capitola (as explants) were directed to a modified solid murashigue and skoog medium with four concentration of tdz (0.25, 0.50, 0.75 and 1.00 mgl-1) for regeneration. three concentr...

objective the aim of this study was to compare the sensitivity and specificity of acid fast and auramine-rhodamine staining and multiplex pcr for the detection of mycobacterium tuberculosiscomplex and non tuberculosis mycobacteria on formalin fixed paraffin embedded tissues (ffpe) materials and methods forty cases of ffpe pleural and bronchial tissue with chronic granulomatous inflammation and ...

Comment about the " Newtonian limit of String-Dilaton Gravity " paper. The objective of this brief comment is to point out several problems associated with the general framework underpinning this paper[1]. For one, analyzing the static, spherically symmetric solution of scalar-tensor, vector-metric as well as string-dilaton theories one can find the following. When the energy-momentum tensor T=...

objective: different cryoprotectants are used for cryopreservation of ovarian tissue in patients at risk of infertility. ethylene glycol (eg), dimethyl sulfoxide (dmso) and propanediol (proh) have been chosen as the basic permeable cryoprotectants due to their decreased glass-formation characteristics compared to other cryoprotectants. in the present study, the effects of two different vitrific...
