خلاصه: سابقه و هدف: کاندیدیازیس یک بیماری قارچی شایع دهان است. اقدام مناسب جهت درمان کاندیدیازیس استفاده از داروهای ضد قارچ میباشد. با توجه به مقاومت دارویی و عوارض شناخته شده داروها، تمایل به استفاده از گیاهان دارویی رو به افزایش است. سیر به عنوان یک ضد باکتریایی قوی شناسایی شده است. لذا در این تحقیق اثر عصاره آبی سیر و نیستاتین بر روی کاندیدا آلبیکنس بررسی گردید. مواد و روش ها: تحقیق به روش ...
Objectives: The purpose of this study was to investigate the effect of restriction sleep treatment on the quality of sleep in the elders. Methods & Materials: The study was a quasi-experimental research. The study population consisted of 5000 elders who were members of jahandidegan center of Shiraz. Sample included 50 elder’s who were selected according to inclusion and exclusion criteria. F...
Objective: To evaluate the capacity of artificial neural network modeling in quantification relative contribution various factors towards happiness index university faculty members and to adjudge degree agreement with results descriptive statistical analysis under hard societal situation. Methods: A relational-research is conducted by statistics ANN 93 variables, grouped into 24 major variables...
Multiple kernel learning (MKL) aims at learning a combination of different kernels, instead of using a single fixed kernel, in order to better match the underlying problem. In this paper, we propose the Empirical Optimal Kernel for convex combination MKL. The Empirical Optimal Kernel is based on the theory of kernel polarization, and is the one with the best generalization ability which can be ...
OBJECTIVE To evaluate the reproducibility of the modified sphygmomanometer compared to hand dynamometer to measure muscle strength of the flexor muscles of fingers. METHODS We assessed 40 healthy volunteers of both genders, aged between 20 and 55 years, who underwent the muscle strength test in the finger flexor muscles on both hands using two instruments for which the comparison was made bet...
We have compared the degree of tetanic fade relative to twitch depression occurring after isolated forearm block with vecuronium and that after systemic i.v. injection. Fifteen patients received either vecuronium 0.3 mg into an isolated forearm or vecuronium 0.05 mg kg-1 systemically. Adductor pollicis mechanomyography was used to monitor recovery of twitch height at 0.2 Hz. At 25, 50, 75 and 1...
The present study was conducted to assess the types of coping styles among the spouses of patients with psychotic disorders like schizophrenia, schizophreniform disorder and schizoaffective disorder. One hundred and sixteen (116 out of which 58 male and 58 female) spouses of diagnosed patients as per the DSM IV TR criteria with psychotic disorders were selected through purposive sampling. The C...
We start this paper by an introduction to evolutionary algorithms and to their biological background. We present a survey of the most important evolutionary schemes found in the literature. We then describe niche search, a genetic-based optimisation approach that we have designed and implemented. It is characterised by an evolutionary search on two layers: the individual layer (which is compara...
Automatic model search procedures aim at identifying the model that maximises a given +tness function, thereby treating model selection as an optimisation problem. However, it is unrealistic to believe that the +ttest model represents the best solution to the search problem. In fact, even if it is possible to score all of the candidate models, it hardly happens that there exists an unequivocal ...
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
