هدف: این مطالعه به منظور بررسی میزان اثربخشی fractional co2 laser در درمان اسکار انجام شده است. روش مطالعه: این مطالعه به صورت یک clinical case series انجام شده است. حجم نمونه مورد بررسی شامل 81 بیمار مبتلا به اسکار بود که طی سال 1388 جهت درمان به کلینیک های درماتولوژی در سطح شهر تهران مراجعه نموده بودند.یافته ها: میانگین میزان پاسخ به درمان در هر جلسه لیزردرمانی 26/29 درصد بود. 20 نفر (7/24 د...
Abstract: Jean Mandler proposes an original and richly detailed theory of how concepts relate to sensory and motor capacities. I focus on her claims about conceptual representations and the processes that produce them. On her view, concepts are declarative representations of object kind information. First, I argue that since sensorimotor representations may be declarative, there is no bar to pe...
In this paper, the event-triggered strategy in the case of finite-horizon model predictive control (MPC) is studied and its advantages over the input to state stability (ISS) Lyapunov based triggering rule is discussed. In the MPC triggering rule, all the state trajectories in the receding horizon are considered to obtain the triggering rule. Clearly, the finite horizon MPC is sub-optimal with ...
OBJECTIVE Although recent experience suggests that transmyocardial laser revascularisation (TMLR) relieves angina, its mechanism of action remains undefined. We examined its functional effects and analysed its morphological features in an animal model of acute ischaemia. METHODS A total of 15 pigs were randomised to ligation of left marginal arteries (infarction group, n = 5), to TMLR of the ...
Ultrafast photoresponse of dc-biased optically-thick YBa2Cu3O7−δ microbridges at T < Tc triggered with 100 fs optical pulses of high fluence was investigated by means of sampling oscilloscope and approach of a S-(1.5– 4 GHz) & C-(4–7 GHz) frequency-band antenna radiation, excited by the photoresponse. A superposition of ultrafast(photokinetic) and slow(bolometric) components of the photorespons...
The collapse of a cavitation bubble is always associated with the radiation intense shock waves, which are highly relevant in variety applications. To radiate strong wave, it necessary to converge energy at collapse, and understanding generation processes multiple waves key issue. In present study, we investigated formation generated by laser-induced bubble. We used high-speed imaging system un...
Coronary artery bypass graft (CABG) surgery is a common treatment for patients with coronary artery disease. A potential complication of CABG is myocardial ischemia or infarction. In this thesis, a method — based on laser Doppler flowmetry (LDF) — for detection of intraand postoperative ischemia by myocardial perfusion monitoring is evaluated. LDF is sensitive to motion artifacts. In previous s...
BACKGROUND The diffuse noxious inhibitory control (DNIC) effect is the neurophysiological basis for the phenomenon that heterotopic "pain inhibits pain" in remote areas of the body. The effect of DNIC is mediated by spino-bulbo-spinal loops and a final postsynaptic inhibitory mechanism. The DNIC effect depends on intensity, duration, quality, and application site of conditioning stimulation and...
