The study investigated the effect of caffeine on physical performance in healthy citizens aged over 70 years following eight hours of abstinence from caffeine containing drinks and foods. ...
It is often assumed that levels of caffeine found in ‘decaffeinated’ beverages are below any psychopharmacological threshold. However, recent findings indicate that caffeine doses as l...
The purpose of this study determine the difference in hemodynamic effects of synthetic and natural caffeine consumption in healthy individuals through blood pressure (central and periphera...
Caffeine is the most widely consumed drinking nutrient in the world. Caffeine effects various organs and the vascular system. It decreases ocular blood flow due to vasoconstriction.
The study investigated the effect of caffeine on physical performance in healthy citizens aged over 70 years. The main hypothesis was that 6 mg/kg caffeine would improve cycling endurance ...
Highly efficient, visible light-driven and a novel ternary hybrid photocatalyst WO-TiO-g-CN with robust stabilities and versatile properties has been synthesized through facile hydrothermal method. Th...
Animal studies suggest that caffeine may interfere with acupuncture analgesia. This study investigated the modulation effect of daily caffeine intake on acupuncture analgesia in 27 healthy subjects us...
Cocoa beans and cocoa products contain considerable amounts of bioactive compounds. Harvesting cocoa fruit too early or too late may have effects on the phenolic and alkaloid concentrations of the coc...
Caffeine has been considered a neuroprotective agent against Parkinson's disease (PD). Recent metabolomic analysis showed that levels of caffeine and its metabolites were decreased in sera from patien...
We investigated the effects of a single instance of caffeine intake on neurocognitive functions and driving performance in healthy subjects using an established cognitive battery and a driving simulat...
A purine base found in most body tissues and fluids, certain plants, and some urinary calculi. It is an intermediate in the degradation of adenosine monophosphate to uric acid, being formed by oxidation of hypoxanthine. The methylated xanthine compounds caffeine, theobromine, and theophylline and their derivatives are used in medicine for their bronchodilator effects. (Dorland, 28th ed)
A methylxanthine naturally occurring in some beverages and also used as a pharmacological agent. Caffeine's most notable pharmacological effect is as a central nervous system stimulant, increasing alertness and producing agitation. It also relaxes SMOOTH MUSCLE, stimulates CARDIAC MUSCLE, stimulates DIURESIS, and appears to be useful in the treatment of some types of headache. Several cellular actions of caffeine have been observed, but it is not entirely clear how each contributes to its pharmacological profile. Among the most important are inhibition of cyclic nucleotide PHOSPHODIESTERASES, antagonism of ADENOSINE RECEPTORS, and modulation of intracellular calcium handling.
Healthy People Programs are a set of health objectives to be used by governments, communities, professional organizations, and others to help develop programs to improve health. It builds on initiatives pursued over the past two decades beginning with the 1979 Surgeon General's Report, Healthy People, Healthy People 2000: National Health Promotion and Disease Prevention Objectives, and Healthy People 2010. These established national health objectives and served as the basis for the development of state and community plans. These are administered by the Office of Disease Prevention and Health Promotion (ODPHP). Similar programs are conducted by other national governments.
Governmental guidelines and objectives pertaining to public food supply and nutrition including recommendations for healthy diet and changes in food habits to ensure healthy diet.
Surgical reinnervation of a denervated peripheral target using a healthy donor nerve and/or its proximal stump. The direct connection is usually made to a healthy postlesional distal portion of a non-functioning nerve or implanted directly into denervated muscle or insensitive skin. Nerve sprouts will grow from the transferred nerve into the denervated elements and establish contact between them and the neurons that formerly controlled another area.
