Brain tissue is metabolically expensive. Consequently, the evolution of humans’ large brains must have occurred via concomitant shifts in energy expenditure and intake. Proposed mechanisms include dietary shifts such as cooking. Importantly, though, any
For respiratory motion correction, we used the DDG algorithm (MOTIONFREE, GE Healthcare) in combination with a motion correction algorithm (Q.STATIC, GE Healthcare), using a phase offset of 30% and a phase window width of 50%, which are the default parameters supplied by the vendor: 1. ...
In an electron-free environment, the operation at room temperature contributes to a more efficient ion extraction. The field produced by the grounded extraction electrode penetrates into the anode volume and decreases the potential near the outlet aperture. Ions created in this region are guided ...

Reliable prognostic biomarkers to distinguish indolent from aggressive prostate cancer (PCa) are lacking. Many studies investigated microRNAs (miRs) as PCa prognostic biomarkers, often reporting inconsistent findings. We present a systematic review of th
It is generally thought that these antioxidants affect certain oxidative and free radical processes involved with some types of tumor promotion. Additionally, some plant polyphenolic compounds that have been shown to be anticarcinogenic, also possess substantial antioxidant activity (Ho et al., 1992; ...
