Geranylgeranylacetone (GGA), an anti-ulcer drug, has been reported to induce heat shock protein (HSP) 70 in several animal organs. The present study was performed to determine whether GGA protects mouse liver against acetaminophen (APAP)-induced injury and whether it has potential as a therapeutic agent for APAP overdose. Hepatic damage was induced by(More)
The aim of the present study was to assess the contribution of the level of expression of heat shock protein 25 (HSP25), 60 (HSP60), 70 (HSC70) and 70i (HSP70i) in mouse livers after a lethal dose of acetaminophen (APAP) to their survival. We examined changes in survival ratio, plasma APAP level and alanine aminotransferase (ALT) activity, and hepatic(More)
A growing body of evidence suggests that phosphatidylserine (PS) oxidation is linked with its transmembrane migration from the inner to the outer leaflet of the plasma membrane during apoptosis. However, there is no direct evidence for the presence of oxidized PS (PSox) on the surface of cells undergoing apoptosis. The present study was performed to detect(More)
Hydrogen peroxide (H(2)O(2)) is generated endogenously during execution of both intrinsic as well as extrinsic apoptotic programs suggesting that it may function as a secondary messenger in apoptotic pathways. In the present study, we investigated the role of endogenously generated H(2)O(2) by using two cell lines-HL-60 cells and its subclone, H(2)O(2)(More)
BACKGROUND Genetic diagnoses provide beneficial information to patients and families. However, traditional genetic diagnoses are often difficult even for experienced clinicians and require recognition of characteristic patterns of signs or symptoms to guide targeted genetic testing for the confirmation of diagnoses. Next-generation sequencing (NGS) is a(More)
SYNGAP1 gene mutation has been associated with epilepsy which is often drug resistant, with seizure types including eyelid myoclonia. However, detailed descriptions, including ictal video-EEG, have not been reported. We report the case of a 4-year-old boy who developed recurrent epileptic eyelid twitching at 1 year and 5 months of age. Seizures gradually(More)
