Laser is considered basically effective for treating periodontal diseases because of its excellent physical properties namely ablation, hemostasis, bacterial killing and cell stimulation. The current laser application mainly used for the treatment of periodontitis is high-power laser ablation (HLLT). Laser ablation of diseased periodontal tissues using the HLLT is widely performed, partly expec...
We have demonstrated an innovative ability of mechanoluminescent (ML) material as a light source for the first time. By appropriate smart size control and nondestructive mechanical stimulation, the ML particle can be considered a promising candidate of in situ light source for bio-imaging and photo-therapy even in a human body.
A spiropyran-based amphiphilic random copolymer was synthesized and self-assembled into photo-, pH-, and thermo-responsive micellar nanoparticles. The triple-stimuli triggered morphological changes of the nanoparticles were revealed by TEM and DLS. Highly efficient controlled release of encapsulated molecules, coumarin 102, from the nanoparticles under stimulation of UV light, acid and the comb...
In this paper, a technique is presented to detect micro-cracks on photo-voltaic cells by infrared thermography. The originality of the system comes from the thermoelectric stimulation used to generate thermal transients at micro-crack locations. These thermal transient are picked-up by an infrared cameras for further detection.
Synchronized bursting is found in many brain areas and has also been implicated in the pathophysiology of neuropsychiatric disorders such as epilepsy, Parkinson's disease, and schizophrenia. Despite extensive studies of network burst synchronization, it is insufficiently understood how this type of network wide synchronization can be strengthened, reduced, or even abolished. We combined electri...
Optoelectrical manipulation has recently gained attention for cellular engineering; however, few material platforms can be used to efficiently regulate stem cell behaviors via optoelectrical stimulation. In this study, we developed nanoweb substrates composed of photoactive polymer poly(3-hexylthiophene) (P3HT) to enhance the neurogenesis of human fetal neural stem cells (hfNSCs) through photo-...
بهره برداری های بی رویه و چند جانبه از منابع معدنی و گیاهی و طبیعت سلسله جبال زاگرس، لطمات جبران ناپذیری به این زیستگاه ها وارد کرده است. با توجه به وجود فلور و فون غنی منطقه دنا، و توان و استعداد تخریب و فرسایش بالای این ناحیه به حفاظت و حراست از این منابع با ارزش توسط مسئولین منطقه نیاز می باشد و لازمه این حراست داشتن شناخت و اطلاعات کافی از وضعیت موجود و توان منطقه می باشد. شهرستان سمیرم واق...
Olfactory stimulation induces an odor-guided crawling behavior of Drosophila melanogaster larvae characterized by either an attractive or a repellent reaction. In order to understand the underlying processes leading to these orientations we stimulated single olfactory receptor neurons (ORNs) through photo-activation within an intact neuronal network. Using the Gal4-UAS system two light inducibl...
Indroduction: The novel model of a non-local elastic semiconductor material that is microelongated created. process photothermal transfer responsible for the stimulation material. Photo-thermoelastic theories are used when thermal conductivity changed medium. Under influence laser pulses, effective framework describes nanoscale microelongation instance as well interference between photo-thermoe...
in this paper, calcium stannate nanoparticles were synthesized by a fast and simple co-precipitation procedure. for casno3 preparation ammonia was used as precipitation agent. the effect of various surfactants such as cationic, anionic and neutral on the morphology of the products was investigated. by changing in ca(sal)2 as a new precursor different morphologies were obtained. ligand as a capp...
