The role of tetrahydroxyquinone solubility on apoptosis induction in human colorectal cells.

Tetrahydroxy-1,4-benzoquinone (THQ) is a highly redox-active substance that generates reactive oxygen species (ROS), which can induce apoptosis in cell culture experiments. The underlying mechanism for ROS production has previously been postulated to be the autoxidation of THQ to rhodizonic acid (RhA). However, our results suggest that the cells detoxify THQ by reducing it to hexahydroxybenzene (HHB), catalyzed by the NADPH-quinone-oxidoreductase (NQO1).

Deep brain stimulation for chronic refractory cluster headache: A case series about long-term outcomes and connectivity analysis.

Objective: The aim of this study was to provide long-term clinical results-including "sweet spot" identification and connectomic imaging analysis-in a series of patients treated with deep brain stimulation for refractory chronic cluster headache.

Background: Deep brain stimulation is a relatively recent indication for the treatment of refractory chronic cluster headache. This indication has generated substantial debate in recent years due to uncertainty surrounding the mechanism of action and the lack of long-term efficacy data.

Cognitive phenotyping of GBA1-Parkinson's disease: A study on deep brain stimulation outcomes.

Background: Heterozygous variants in the glucocerebrosidase (GBA1) gene are the most common genetic risk factor for Parkinson's Disease (PD). GBA1-PD patients exhibit earlier disease onset, severe motor impairment, and heightened cognitive decline. Deep Brain Stimulation (DBS) offers motor improvement for PD patients, but its cognitive effects, particularly in GBA1-PD, are debated.
