TL;DR: The real and exciting possibility that caffeine consumption might be a prophylactic strategy and A2A receptor antagonists may be a novel therapeutic option to manage memory dysfunction both in AD and in other chronic neurodegenerative disorders where memory deficits occur is opened.
Abstract: Caffeine, the most widely consumed psychoactive drug, enhances attention/vigilance, stabilizes mood, and might also independently enhance cognitive performance. Notably, caffeine displays clearer and more robust beneficial effects on memory performance when memory is perturbed by stressful or noxious stimuli either in human or animal studies. Thus, caffeine restores memory performance in sleep-deprived or aged human individuals, a finding replicated in rodent animal models. Likewise, in animal models of Alzheimer's disease (AD), caffeine alleviates memory dysfunction, which is in accordance with the tentative inverse correlation between caffeine intake and the incidence of AD in different (but not all) cohorts. Caffeine also affords beneficial effects in animal models of conditions expected to impair memory performance such as Parkinson's disease, chronic stress, type 2 diabetes, attention deficit and hyperactivity disorder, early life convulsions, or alcohol-induced amnesia. Thus, caffeine should not be viewed as a cognitive enhancer but instead as a cognitive normalizer. Interestingly, these beneficial effects of caffeine on stress-induced memory disturbance are mimicked by antagonists of adenosine A2A receptors. This prominent role of A2A receptors in preventing memory deterioration is probably related to the synaptic localization of this receptor in limbic areas and its ability to control glutamatergic transmission, especially NMDA receptor-dependent plasticity, and to control apoptosis, brain metabolism, and the burden of neuroinflammation. This opens the real and exciting possibility that caffeine consumption might be a prophylactic strategy and A2A receptor antagonists may be a novel therapeutic option to manage memory dysfunction both in AD and in other chronic neurodegenerative disorders where memory deficits occur.

TL;DR: In this paper, the microstructure and mechanical properties of friction stir welds were analyzed and compared with two different tools, and the results showed that the hot welds, obtained with the maximum tool rotational speed and the minimum traverse speed, have improved mechanical properties relative to the cold welds that were in undermatch condition relative to a base material.

18 Apr 2005TL;DR: A feature detection system for real-time identification of lines, circles and people legs from laser range data is developed and a new method suitable for arc/circle detection is proposed: the Inscribed Angle Variance (IAV).
Abstract: A feature detection system has been developed for real-time identification of lines, circles and people legs from laser range data. A new method suitable for arc/circle detection is proposed: the Inscribed Angle Variance (IAV). Lines are detected using a recursive line fitting method. The people leg detection is based on geometrical relations. The system was implemented as a plugin driver in Player, a mobile robot server. Real results are presented to verify the effectiveness of the proposed algorithms in indoor environment with moving objects.

11 Jul 2017TL;DR: In this article, the advantages and disadvantages of teleworking are outlined, as well as its effects on the health of the worker. And the overall conclusion is that telework is likely to yield more good than bad for individual health.
Abstract: Telework is an increasingly popular flexible working arrangement. The aim of this article is to describe the features that characterize telework. The advantages and disadvantages of teleworking are outlined, as well as its effects on the health of the worker. The method used was a literature review. The outputs of this search show that in general, empirical evidence favours a positive association between telework and worker health. However, there are also negative impacts on health such as stress and depression. The overall conclusion is that telework is likely to yield more good than bad for individual health.
