Article Synopsis
  • A study investigated the effects of simple renal cysts (SRC) on thoracic aortic aneurysm (TAA) treatment outcomes after thoracic endovascular aortic repair (TEVAR).
  • Among 103 patients, those with SRC experienced significantly less shrinkage of aneurysm sacs one year post-surgery compared to those without SRC (23.9% vs 59.6%).
  • The findings suggest that having SRC may be a predictor of poor aneurysm sac shrinkage outcomes after TEVAR, indicating a need for careful monitoring in these patients.

The combined effect of green tea and α-glucosyl hesperidin in preventing obesity: a randomized placebo-controlled clinical trial.

Sci Rep

September 2021

Division of Applied Biological Chemistry, Department of Bioscience and Biotechnology, Faculty of Agriculture, Kyushu University, 744 Motooka, Nishi-ku, Fukuoka, 819-0395, Japan.

Green tea, a widely consumed beverage in Asia, contains green tea catechins effective against obesity, especially epigallocatechin-3-O-gallate (EGCG), but must be consumed in an impractically huge amount daily to elicit its biological effect. Meanwhile, citrus polyphenols have various physiological effects that could enhance EGCG functionality. Here we investigated the antiobesity effect of a combination of EGCG and α-glucosyl hesperidin, a citrus polyphenol, at doses that have not been previously reported to exert antiobesity effects by themselves in any clinical trial.

Although Venus is a terrestrial planet similar to Earth, its atmospheric circulation is much different and poorly characterized. Winds at the cloud top have been measured predominantly on the dayside. Prominent poleward drifts have been observed with dayside cloud tracking and interpreted to be caused by thermal tides and a Hadley circulation; however, the lack of nightside measurements over broad latitudes has prevented the unambiguous characterization of these components.

Terrestrial exoplanets orbiting within or near their host stars' habitable zone are potentially apt for life. It has been proposed that time-series measurements of reflected starlight from such planets will reveal their rotational period, main surface features and some atmospheric information. From imagery obtained with the Akatsuki spacecraft, here we show that Venus' brightness at 283, 365, and 2020 nm is modulated by one or both of two periods of 3.
