Exposure to DNA damaging agents is known to induce an adaptive response in a variety of eukaryotic cells. Cells can become radioresistant to the damaging effects of ionizing radiation when pretreated with a lower, conditioning radiation dose [l]. An adaptive response has been described for a variety of eukaryotic cells exposed to numerous chemical and physical agents, in particular ioinizing ra...

This research was designed to study sexual differences in place conditioning induced by morphine in offspring born of female Wistar rats mated with drug-naïve males. Mothers were exposed to morphine during the 14th-16th days of gestational. Control dams were simply saline-injected. Female and male virgin offspring born of morphine-treated or saline-treated mothers were separately housed until b...

Infrared lasers are ideally suited for the selective and precise removal of carious dental hard tissue while minimizing the healthy tissue loss. Since the initial investigations of Stern[1] over 30 years ago, several unique laser applications have evolved for dentistry, namely laser ablation of dental hard tissue, caries inhibition treatments by localized surface heating, and surface conditioni...

A local so-called laser-micro-annealing (LMA) conditioning technology, which is suitable for the fabrication of a large range hybrid nano-optoelectronic devices, was applied to III-nitride-based nano-light emitting diodes (LEDs). The LEDs with diameter ∼100 nm were fabricated in area arrays and designed optoelectronic applications. LMA process developed precise LED nano-structures. Photolumines...

the purpose of the present study was to determine the role of medial prefrontal cortex (mpfc) dopaminergic system in fear conditioning response considering individual differences. animals were initially counterbalanced and classified based on open field test, and then were given a single infusion of the dopamine agonist, amphetamine (amph) and antagonist, clozapine (clz) into the medial prefron...

This paper deals with the experimental results of a xenon flash-lamp pumped passively Q-switched Nd:YAG laser using Cr4+:YAG saturable absorber. The need of a laser cavity to be integrated into a time-of-flight laser range finder is of great interest as an experimental investigation of several laser resonators. Two types of laser resonator, with different lengths, have been studied: the flat-fl...

Nowadays laser is extensively used in various industrial, communicative, medical, and other fields. Using laser in medicine has enabled physicians to perform the most accurate and finest operations within few minutes. Non-observance of safety points during laser performance could be seriously harmful for the medical staff and the patient. Therefore, in order to prevent the possible damage of th...
