Cationic compounds with quaternary ammonium functional groups are used extensively in personal care product applications. One important class of such quaternary ammonium compounds is cationically charge-modified polymers derived from various animal and plant sources, including guar gum, cellulose, proteins, polypeptides, chitosan, lanolin, starches and amino silicones. These polymers have a dem...

Evaluative conditioning (EC) procedures can be used to form and change attitudes toward a wide variety of objects. The current study examined the effects of a negative EC procedure on attitudes toward chocolate, and whether it influenced chocolate evaluation and consumption. Participants were randomly assigned to the experimental condition in which chocolate images were paired with negative sti...

Colchicine, a potent neurotoxin derived from plants, has been recently introduced as a degenerative toxin of small pyramidal cells in the cortical area 1 of the hippocampus (CA1). In this study, the effect of the alkaloid in CA1 on the behaviors in the conditioning task was measured. Injections of colchicine (1,5 μg/rat, intra-CA1) was performed in the male Wistar rats, while the animals were s...

As physical sensing becomes more and more pervasive, the need for accurate and efficient wireless sensors and communication nodes become important. A Wireless Sensor node is a platform which has basic components like a sensor, conditioning circuit and data communication. A set of such nodes spatially distributed in order to co-operatively sense and pass the data forms a Wireless Sensor Network ...

OBJECTIVE To identify factors associated with the minimal clinically important difference (MCID) for health-related quality of life (HRQoL) after physical conditioning in patients with COPD. METHODS Thirty-five patients were submitted to a 12-week program of physical conditioning (strength training plus low-intensity aerobic exercise). Body composition, incremental treadmill test results, end...

introduction: one of the hallmark symptoms of posttraumatic stress disorder (ptsd) is the impaired extinction of traumatic memory. single prolonged stress (sps) has been suggested as an animal model of ptsd, since sps rats exhibited the impaired fear extinction. oxytocin (oxt) has been recently suggested as a potential pharmacotherapy for treatment of ptsd. in this study, using sps rats we inve...

introduction: biological effects of magnetic fields have been investigated by scientists for many years and a vast amount of research using different frequencies and intensities have been performed on humans and laboratory animals. the results of these studies, which have mostly been done by applying high frequencies, have shown that electromagnetic fields are effective on structure and functio...

statement of problem: the achievement of a good and durable dentin/composite resin bond is an important task in restorative dentistry. the application of acid conditioners and dentin bonding agents is an accepted method to enhance this bond strength. pretreating of dentin surface by laser irradiation seems to be a supplemental way to obtain better results, since lased dentin is more roughened a...
