SUMO2 rescues neuronal and glial cells from the toxicity of P301L Tau mutant.

Introduction: Abnormal intracellular accumulation of Tau aggregates is a hallmark of Alzheimer's disease (AD) and other Tauopathies, such as Frontotemporal dementia (FTD). Tau deposits primarily affect neurons, but evidence indicates that glial cells may also be affected and contribute distinctively to disease progression. Cells can respond to toxic insults by orchestrating global changes in posttranslational modifications of their proteome.

Effects of transcutaneous electrical nerve stimulation on acute postoperative breast augmentation pain: study protocol.

The aim of this study is to describe a protocol for evaluating the effects of transcutaneous electrical nerve stimulation (TENS) on pain following breast augmentation surgery. Fifty-four women will be randomly allocated into two groups: active TENS and placebo. Pain will be assessed at rest and during movement, before and immediately after TENS application.

Sol-Gel Pt-VO Films as Selective Chemoresistive and Optical H Gas Sensors.

In this work, VO (M1/R) thin films were exploited as H gas sensors. A flat film morphology, obtained by furnace annealing, was compared with a laser-induced nanostructured one. The combination of the environmentally friendly sol-gel approach with the ultrafast laser crystallization allows for significant reductions in energy consumption and related emissions during the fabrication of VO sensors.

SARS-CoV-2 Nucleocapsid Protein Induces Tau Pathological Changes That Can Be Counteracted by SUMO2.

Neurologic manifestations are an immediate consequence of SARS-CoV-2 infection, the etiologic agent of COVID-19, which, however, may also trigger long-term neurological effects. Notably, COVID-19 patients with neurological symptoms show elevated levels of biomarkers associated with brain injury, including Tau proteins linked to Alzheimer's pathology. Studies in brain organoids revealed that SARS-CoV-2 alters the phosphorylation and distribution of Tau in infected neurons, but the mechanisms are currently unknown.
