introduction: purkinje cell (pc) output displays a complex firing pattern consisting of high frequency sodium spikes and low frequency calcium spikes, and disruption in this firing behavior may contribute to cerebellar ataxia. riluzole, neuroprotective agent, has been demonstrated to have neuroprotective effects in cerebellar ataxia. here, the spectral analysis of pcs firing in control, 3-acety...

In the present study, the interaction between water-soluble cationic asymmetric porphyrin, 5-(1-Hexadecyl pyridinium-4-yl)-10, 15, 20-tris (1-Butyl pyridinium-4-yl) Porphyrin Chloride, and its copper (II) derivative with calf thymus DNA (CT-DNA) were studied by means of spectroscopic techniques, viscosity measurements and molecular docking. The monitoring of the changes in visible absorbance sp...

Based on the accumulated data, FTIR spectroscopy seems to be a highly sensitive tool in cervical cancer diagnosis. We, therefore, employed this technique in a screening type of research here in Tehran. The purpose of this study was to look for the spectral pattern differences between normal and malignant cervix samples in Iranian women. Through formal and informal announcements, all gynecology ...

Discussion: A large part of both clinical and subclinical lesions found in our daily work are benign and correspond with fibrocystic changes (FCC). This entity is complex and part exhibit traits that define characteristically in MRI and diagnose correctly, but there is another small group of changes that can take the image aspect of cancer. From a complex case, we review the main aspects of the...

Nowadays, remote sensing and GIS technologies are used as a key element in monitoring of land use and vegetation changes. Using this method as one the main sources receiving and updating information on the Earth's surface changes, plays an important role in the management of ecosystems. The present study aims to investigate land use change, vegetation dynamics and trend of Hamoun wetland betwee...

Extended abstract 1- Introduction Land use reflects the interactive characteristics of humans and the environment and describes how human exploitation works for one or more targets on the ground. Land use is usually defined based on human use of the land, with an emphasis on the functional role of land in economic activities. Land use, which is associated with human activity, is changing over...
