TLDR
Caffeine is the most widely consumed behaviorally active substance in the world and almost all caffeine comes from dietary sources (beverages and food).Abstract:
Caffeine is the most widely consumed behaviorally active substance in the world. Almost all caffeine comes from dietary sources (beverages and food), most of it from coffee and tea. Acute and, especially, chronic caffeine intake appear to have only minor negative consequences on health. For thisread more

International Union of Pharmacology. XXV. Nomenclature and Classification of Adenosine Receptors
TL;DR: Experiments with receptor antagonists and mice with targeted disruption of adenosine A(1), A(2A), and A(3) expression reveal roles for these receptors under physiological and particularly pathophysiological conditions.

The Role and Regulation of Adenosine in the Central Nervous System
TL;DR: A role for adenosine in a diverse array of neural phenomena, which include regulation of sleep and the level of arousal, neuroprotection, regulation of seizure susceptibility, locomotor effects, analgesia, mediation of the effects of ethanol, and chronic drug use, is established.

Control of Sleep and Wakefulness
TL;DR: Genetic studies suggest that brain mechanisms controlling waking and NREM sleep are strongly conserved throughout evolution, underscoring their enormous importance for brain function.

The neurobiology and control of anxious states
TL;DR: The present article focuses in particular upon the multifarious and complex roles of individual modulators, often as a function of the specific receptor type and neuronal substrate involved in their actions; novel targets for the management of anxiety disorders; the influence of neurotransmitters and other agents upon performance in the VCT; data acquired from complementary pharmacological and genetic strategies and, finally, several open questions likely to orientate future experimental- and clinical-research.

TL;DR: Although using the hypoxia→adenosine→A2AR pathway inhibitors may improve antitumor immunity, the recruitment of this pathway by selective drugs is expected to attenuate the autoimmune tissue damage.

Physical dependence increases the relative reinforcing effects of caffeine versus placebo
TL;DR: Findings provide the strongest evidence to date indicating that caffeine physical dependence increases the relative reinforcing effects of caffeine versus placebo.

Effect of decaffeinated versus regular coffee on blood pressure. A 12-week, double-blind trial.
TL;DR: It is concluded that in normotensive adults replacement of regular by decaffeinated coffee leads to a real but small fall in blood pressure, however, it remains to be established whether a mass switch from regular to decaffinated coffee would significantly reduce the total incidence of hypertension-related disorders.

Tea: the plant and its manufacture; chemistry and consumption of the beverage.
TL;DR: In this paper, a complete understanding of the chemistry of the mass of oxidized phenolic material, commonly known as thearubigens but better classified as unknown polyphenols, is presented.

Behavioral and physiological effects of xanthines in nonhuman primates.
TL;DR: Converging lines of evidence suggest that adenosine A2 and cAMP-specific PDE mechanisms play especially prominent roles in mediating the behavioral and physiological effects of xanthines in nonhuman primates.
