INCREASE OF BRAIN TAURINE CONTENTS OF EL MICEBY PHYSIOLOGICAL STIMULATION

Physiological actions of taurine.

MECHANISMS OF BLOOD FLOW INCREASE INDUCED BY ELECTRICAL STIMULATION

Previous studies have shown that electrical stimulation (ES) increases blood flow, but the exact mechanisms are not clear. The present study was designed to clarify some of the underlying mechanisms involved in this phenomenon. White adult rabbits Lt.-6 months old were used. Animals were anesthetized by sodium pentobarbital (40 mg/kg, IV) and skin blood flow in the thoracic back was recorde...

molecular and physiological characterizations of floral scent production in rosa damascena mill.

گل محمدی (r. damascena mill.)مهمترین گونه ای است که در تولید گلاب، عطر و اسانس، در صنعت عطرسازی و دارویی کاربرد دارد. با وجود اهمیت عطر گل محمدی، پژوهش های مولکولی و بیوشیمیایی عطر گل این گونه هنوز در مراحل ابتدایی است. در این پژوهش، ویژگی های مولکولی و فیزیولوژیکی تولید عطر در گل محمدی در آزمایش های مختلف مورد بررسی قرار گرفتند. در آزمایش اول، پژوهشی به منظور بررسی تنوع شیمیایی اسانس میان 44 ت...

Successful physiological aging and episodic memory: a brain stimulation study.

Functional neuroimaging studies have shown that younger adults tend to asymmetrically recruit specific regions of an hemisphere in an episodic memory task (Hemispheric Encoding Retrieval Asymmetry-HERA model). In older adults, this hemispheric asymmetry is generally reduced as suggested by the Hemispheric Asymmetry Reduction for OLDer Adults-HAROLD-model. Recent works suggest that while low-per...

3. Physiological and therapeutic roles of taurine in the heart

Taurine is the most abundant free amino acid in the heart. However, unlike the classical β-amino acids, taurine is a β-amino acid with the acid moiety being a sulfonic acid group rather than a carboxyl group; the lack of a carboxyl group excludes the involvement of taurine in peptide bond formation. Nonetheless, there is abundant evidence that taurine is an essential nutrient in certain species...
