Accumulating evidence suggests that repeated seizures could induce endoplasmic reticulum (ER) stress. Inositol-requiring protein 1α (IRE1α) is a vital pro-apoptotic molecule in ER stress, but it remains unclear whether the signaling pathway mediated by IRE1α is involved in human temporal lobe epilepsy. In this report, we investigated IRE1α-mediated ER stress ...

To ensure respiratory stability and flexibility, healthy breathing shows balanced variability consisting of considerable correlated variability (parameters of each breath are correlated to parameters of adjoining breaths) and some random variability. Sighing resets this balance when respiration lacks variability or becomes excessively irregular. The present study aimed to investigate the ...

Obesity and overweight are often defined by the body mass index (BMI), which associates with metabolic and cardiovascular disease, and possibly with dementia as well as variations in brain volume. However, body fat distribution and abdominal obesity (as measured by waist circumference) is more strongly correlated with cardiovascular and metabolic ...
