Summary: This study aimed to examine the effects of expectations on neurocognitive processes. By manipulating the conditions of coffee consumption, the researchers found that the effects of caffeine on attention and inhibitory control may have been overestimated, and caffeine primarily influences cognitive processes and brain areas responsible for attention allocation.

Summary: This study investigated the relationship between daily coffee intake and vascular function in patients with hypertension. The findings suggest that moderate coffee consumption may have beneficial effects on endothelial function and vascular smooth muscle function in these patients.

Summary: In recent decades, there have been numerous studies investigating the effects of oral caffeine intake on fat oxidation. However, there has been no bibliometric analysis to assess the research activity in this field. This study conducted a bibliometric and visual analysis to assess the scientific output regarding oral caffeine intake and fat oxidation rate. The findings demonstrate that this is a nutrition research area with a strong foundational base of scientific evidence, and future research should focus on the effects of sex and caffeine tolerance on fat burning, as well as translational research in ecologically valid contexts.

Summary: In this study, it was found that extraction under reduced pressure may be the best method for accelerating cold brew coffee extraction, with vacuum cycles and duration of each cycle significantly affecting caffeine concentration and yield. Experimental results indicate that optimal values can be determined to obtain the highest extraction yield and phenol concentration.

Summary: This study examined the caffeine intake of Chinese adults from 2004 to 2018. The average daily caffeine intake was 123 mg for male consumers and 116 mg for female consumers, with traditional tea leaves, coffee, and sodas being the main sources. While most Chinese adults consumed caffeine within the safe level, there has been an increasing trend in caffeine consumption over the past 14 years.

Summary: This study analyzed the 'cold finger effect' as a significant uncertainty contribution in measuring the Seebeck coefficient of thermoelectric materials. Using fundamental laws of thermoelectric circuits, the study explained the influence of this effect and presented results from finite element simulations and practical measurements of an ISOTAN(R) sample under different conditions. It was shown that up to a few percent relative errors in the Seebeck coefficient can occur if measurements are conducted under non-optimum conditions, but the thermal coupling of probes to the sample can minimize the influence of the cold finger effect on the measured coefficient.

Summary: This study evaluates the caffeine intake levels from tea among Chinese adult consumers. The caffeine content in tea was found to be fully soluble in water, with an average intake of 180 mg/day. Green, dark, and black tea were the main sources of caffeine. Males consumed more caffeine on average, but females older than 71 years had the highest intake level. Over 90% of Chinese adult tea drinkers had a caffeine intake below 400 mg/day.

Summary: This study applied EC-SERS spectroscopy to detect caffeine intake from human saliva, showing that low-dose caffeine consumption can be detected by the appearance of characteristic SERS bands of caffeine and paraxanthine at 692 cm(-1). The method proved to be viable for clinical applications with a detection limit of paraxanthine in saliva as low as 15 mu M, which can be further improved.

Summary: This study found that daily caffeine intake leads to a slow elimination of caffeine and an accumulation of its primary metabolite, paraxanthine. Furthermore, acute caffeine deprivation resulted in reduced gray matter intensity and increased cerebral blood flow.
