The presence of a food-entrainable oscillator (FEO) independent from the SCN is now well established, but until now its location and characterization have been elusive. Because its expression requires priming of the animal's metabolism toward a catabolic state, it is possible that metabolic rhythms may be related to FEO. The present study was designed to determine whether metabolic rhythms pers...
A major challenge limiting the practical applications of nanomaterials is that the activities of nanostructures (NSs) increase with reduced size, often sacrificing their stability in the chemical environment. Under oxidative conditions, NSs with smaller sizes and higher defect densities are commonly expected to oxidize more easily, since high-concentration defects can facilitate oxidation by en...
Mammals exhibit daily anticipatory activity to cycles of food availability. Studies on such food anticipatory activity (FAA) have been conducted mainly in nocturnal rodents. They have identified FAA as the behavioral output of a food entrained oscillator (FEO), separate of the known light entrained oscillator (LEO) located in the suprachiasmatic nucleus (SCN) of hypothalamus. Here we briefly re...
The spatial distribution of single Au atoms on a thin FeO film has been investigated by low-temperature scanning tunneling microscopy and spectroscopy. The adatoms preferentially adsorb on distinct sites of the Moiré cell formed by the oxide layer and the Pt(111) support and arrange into a well-ordered hexagonal superlattice with 25 angstroms lattice constant. The self-organization is the conse...
effect of fruit essential oil on ephedrine induced manic like behavior: evidence from a new protocol
introduction: estimating ephedrine’s effect on animal’s locomotor activity and evaluation of cumin fruit essential oil (feo) effect and mechanism of ephedrine-induced hyper-locomotion. methods: a new protocol developed for evaluation of manic behavior induced by ephedrine in a dose and time dependent manner. following the suppressive effects of cumin feo on acquisition and expression of ephedri...
CONTEXT Hemiparesia changes quality of life of patients with stroke making difficult a normal life. OBJECTIVE To evaluate the effect of Functional Eletric Orthesis (FEO) applied over the paretic leg in the quality of life of stroke patients. METHOD The quality of life of 50 stroke patients of Associacao de Assistencia a Crianca Deficiente (AACD) was evaluated with SF-36 questionnaire before...
Daily scheduled feeding is a potent time cue that elicits anticipatory activity in rodents. This food-anticipatory activity (FAA) is controlled by a food-entrainable oscillator (FEO) that is distinct from light-entrained oscillators of the suprachiasmatic nucleus (SCN). Circadian rhythms within the SCN depend on transcription-translation feedback loops in which CLOCK protein is a key positive r...
introduction: nitric oxide (no) is a neuronal messenger molecule in the central nervous system, which is generated from l-arginine by nitric oxide synthase (nos) and involves in many important opioid-induced effects. our previous studies revealed that cuminum cyminum interestingly reduces morphine sensitization, tolerance and dependency in male mice. therefore, in the present study, the effect ...
Reactions of the free radical nitrogen monoxide (NO) with metal–oxygen species of metalloproteins are relevant to NO metabolism and detoxification. For example, oxyhemoglobin and oxymyoglobin react with NO to form nitrate. The ferryl state of these globins also reacts with NO to reduce them to the Fe state, forming nitrite. This has led to the suggestion that the role of NO could be that of an ...
The dissociative recombination (DR) of FeO(+) ions with electrons has been studied in a flowing afterglow reactor. FeO(+) was generated by the pulsed laser ablation of a solid Fe target, and then entrained in an Ar(+) ion/electron plasma where the absolute electron density was measured using a Langmuir probe. A kinetic model describing gas-phase chemistry and diffusion to the reactor walls was ...
