METHODS. In this retrospective case series, 72 eyes of 57 consecutive patients who underwent vitrectomy for DME were included. Retinal images dissecting the fovea horizontally were obtained using OCT before and after vitrectomy. After identification of the disc margin and the presumed foveal center, the papillofoveal distance was measured on the OCT images. The association of the distance with ...

We present an approach for learning an anisotropic RBF kernel in a game theoretical setting where the value of the game is the degree of separation between positive and negative training examples. The method extends a previously proposed method (KOMD) to perform feature re-weighting and distance metric learning in a kernel-based classification setting. Experiments on several benchmark datasets ...

Background: Neck roots lesion is one of the reasons for cervical and arm pain. A detailed patient evaluation could improve diagnose, reduce imaging requests, and speedy treatment of cervical pain. We tried to estimate the utility of pronator teres reflex in C6 and C7 roots irritation. Methods: Present study is composed of 118 participants including 56 with C6 and C7 lesion and 62 normal contro...

the purpose of this study was to investigate the validity of the modified ashworth scale (mas) by using both the conventional (hmax/mmax ratio) and the new indicators (hslp/mslp) of motoneuron excitability. this research was a correlational study on twenty post-stroke patients. main outcome measures were the mas and electrophysiologic assessments. the latter was performed using both conventiona...

Abstract Introduction Agricultural intensification results in biodiversity loss through land conversion and management practices which negatively impact arthropods. The abundance diversity of ground-dwelling predators, e.g. ground beetles (Coleoptera: Carabidae) spiders (Araneae), are affected by soil disturbances such as tillage. Reducing can potentially conserve arthropod populations the fiel...

the purpose of the this study was to investigate the effect of direct current on montoneuron reflex exitability. thirty six subjects (18 males, 18 females) 19.36 years of age ( x= 24.06, sd= 3.63) participated in this study. the reflex excitability of soleus motoneruons was assessed by measuring the amount of change in the peak to peak ampitude of the h-reflex before and after direct current wa...

purpose: to evaluate the incidence of the oculo-cardiac reflex (ocr) and its associated risk factors during strabismus surgeries performed at a tertiary referral center between 1390 and 1392. methods: over a 2-year period, all strabismus surgery candidates were enrolled in the study after obtaining consent from the patients or their parents. vital signs were recorded before the initiation of th...

BACKGROUND AND OBJECTIVES Epidural approach angle is one of the determining factors for needle traveling length to reach the epidural space. Likewise, the margin of safety against accidental dural puncture should be affected by epidural approach angle because the space available for epidural needle tip movement in the epidural space is depending on the inserting angle to the epidural space. The...
