in the present work the magnitudes of pigments in the synthetic leather, were measured by means of scanner. initially synthetic leather samples pigmented by three different pigments of yellow, blue and red colors were prepared. then the pigmented samples were scanned, and the values of rgb of images were calculated. the artificial neural network (ann) method used to make relation between rgb va...

A unifying theory of general anesthetic-induced unconsciousness must explain the common mechanism through which various anesthetic agents produce unconsciousness. Functional-brain-imaging data obtained from 11 volunteers during general anesthesia showed specific suppression of regional thalamic and midbrain reticular formation activity across two different commonly used volatile agents. These f...

Dowling-Degos disease is one of the genodermatoses presenting with acquired reticulate pigmentation flexures, black-dot papules, and pitted scars. Numerous associated conditions multiple variants have been reported in literature. Several gene mutations play a role pathogenesis giving rise to phenotypic expressions. Herein, we discuss case three generations family affected shed light on associat...

In this paper we focus on the problem of automatic classification of melanocytic lesions, aiming at identifying the presence of reticular patterns. The recognition of reticular lesions is an important step in the description of the pigmented network, in order to obtain meaningful diagnostic information. Parameters like color, size or symmetry could benefit from the knowledge of having a reticul...

Introduction: Hedera helix is an evergreen plant used in treatment of wounds in the Iranian folk medicine. One of the main stages in wound healing process is, the proliferative phase in which fibroblasts proliferate within the wounds and produce extracellular matrix. Collagen is the main constituent of extracellular matrix. So the aim of this study was to evaluate the effect of Hedera helix alc...

Neuronal response synchronization with millisecond precision has been proposed to serve feature binding in vision and should therefore, like visual experience, depend on central states. Here we test this hypothesis by examining the occurrence and strength of response synchronization in areas 17 and 18 of anesthetized cats as a function of central states. These were assessed from the frequency c...

Acute experiments on cats under chloralose anesthesia were designed to study the role of the brain stem in the transmission of the interhemispheric delayed response (IDR). Experiments on interaction of potentials recorded in brain stem and at cortex led to the conclusion that the IDR is relayed to the contra-lateral hemisphere via routes which pass through the general area of the mesencephalic ...

We used laser scanning photostimulation through a focused UV laser of caged glutamate in an in vitro slice preparation through the rat's somatosensory thalamus to study topography and connectivity between the thalamic reticular nucleus and ventral posterior lateral nucleus. This enabled us to focally stimulate the soma or dendrites of reticular neurons. We were thus able to confirm and extend p...
