AIMS To delineate the entire Zinn-Haller arterial ring angiographically in vivo. METHODS 382 highly myopic eyes (210 patients) with refractive errors greater than -8.25 D were examined using indocyanine green (ICG) videoangiography. A control group of 80 eyes (40 patients) had refractive errors within plano +/- 3D. RESULTS The Zinn-Haller ring was visible in 206 of 382 highly myopic eyes (5...

Local cerebral metabolic rate for glucose was studied utilizing 18F-2-fluoro-2-deoxy-D-glucose and positron emission tomography (PET) in 14 chronically alcohol-dependent patients and 8 normal control subjects of similar age and sex. Nine of the 14 patients (Group A) had clinical signs of alcoholic cerebellar degeneration, and the remaining 5 (Group B) did not have signs of alcoholic cerebellar ...

The habit-forming effects of abused drugs depend on the mesocorticolimbic dopamine system innervating the nucleus accumbens (NAcc). To examine whether different NAcc subterritories (core and medial shell) exhibit a differential distribution of neurons showing phasic firing patterns correlated with drug-seeking behavior, rats were trained to self-administer cocaine, and activity of single NAcc n...

Two patients-one with a terrible triad fracture dislocation and one with an anterior olecranon fracture dislocation—weretreated for maltracking of the elbow (medial subluxation). The radial head articulated with the lateral trochlea while theulnar trochlear notch was perched over the medial trochlea. The late revision surgery could not correct the subluxationbecause the joints were accustomed t...

PURPOSE To evaluate the treatment results of intraarticular injection according to the frequency of hyaluronic acid with mesenchymal stem cells on the osteochondral defect of rabbits' medial femoral condyles. MATERIALS AND METHODS A 5 mm diameter and 4 mm depth osteochondral defect was made on the medial femoral condyles of 18 rabbits, divided into six groups. One week after osteochondral def...

Estrogen receptor (ER)beta is present in hypothalamic and limbic neurons of female rat brains, but little is known about its regulation under physiological conditions. To determine whether ER beta expression varies during physiological conditions in which sex steroid hormone profiles are significantly different, we used in situ hybridization to assess ER beta mRNA expression in the periventricu...

Pause plays important roles for the intelligibility, naturalness and fluency of speech. This paper reported the effect of native (L1) Bengali speakers’ fluency of English on occurrence probability and duration of sentencemedial pauses with respect to three factors: phrase type, phrase length (l), distance (d). In this analysis, 40 nonnative (L2) English (L1 Bengali) speakers’ data was divided i...
