Caffeine, the main component of coffee and energy drinks, is the most widely used psychoactive drug in the world. While caffeine can improve cognitive abilities and alertness, its health risks, especially in energy drinks, have been a cause for concern. However, research suggests that moderate coffee consumption can have various health benefits, such as improved mood, lower risk of depression and Parkinson's disease, and potential heart health benefits. On the other hand, excessive consumption of caffeine, particularly in energy drinks, can lead to adverse effects on health, including increased heart rate and blood pressure. It is recommended to consume caffeine in moderation and consult a doctor if there are any concerns. [Extracted from the article]

A large variety of natural plants are widely produced and utilised because of their remarkable pharmacological effects. In this study, two phenolic glycosides were isolated for the first time from Vanilla pompona Schiede (Orchidaceae) from Kyushu, Japan: bis [4-(β -D – O-glucopyranosyloxy)-benzyl] (S)-2-isopropylmalate (1) and bis 4-[ β -D- O -glucopyranosyloxy)-benzyl]-(2 R ,3 S)-2-isopropyl tartrate (2). We have discovered that the crude extract of V. pompona leaves and stems and its two phenolic glycosides (compounds 1 – 2) are highly effective in reversing skin senescence. V. pompona and compounds 1 – 2 were found to promote the synthesis of collagen, hyaluronic acid, and elastin in skin fibroblasts in a normal skin cell model; in a replicative senescence model, V. pompona and compounds 1 – 2 significantly reduced the ageing phenotype in skin fibroblasts. These compounds also demonstrated a significant protective effect in a UV-induced photo-senescence model; the possible mechanisms of this effect were investigated in this study. To the best of our knowledge, this study is the first to develop V. pompona leaves and stems as new sources of bioactive compounds and to examine their therapeutic potential for skin senescence.

Vines are highly responsive to agricultural management techniques, such as training systems. Three training systems, i.e., conventional, high, and double training, for the 'Niagara Rosada' vine were studied considering aspects related to the yield, physicochemical, and antioxidant characteristics of the grapes. The experiment was carried out during two seasons (2017 and 2018), and the vines grafted on IAC 572 Jales. The training systems did not influence the fruit production per vine and yield of the 'Niagara Rosada' table grape, but some improvements were observed, such as a greater number of berries per bunch in vines managed in the conventional training systems and a higher fresh mass of berries when cultivated in the high and double training systems. Grapes from the double training system had higher soluble solids contents, an important sensorial characteristic in table grapes. The high training system, in turn, provided 'Niagara Rosada' table grapes with a greater content of bioactive compounds (e.g., phenolic compounds, flavonoids, and anthocyanins) and antioxidant activity.
