In the in vitro models, the extract scavenged stable free radical (1, 1-diphenyl-2-picrylhydrazyl; DPPH) in a concentration-dependent manner with an IC50 of 20.10+/-0.78 mu g/ml. The extract protected the erythrocytes from free radical (2, 2′-azobis (2-amidinopropane) dihydrochloride; AAPH)-induced hemolysis
with an IC50 of 74.22+/-9.87 mu g/ml. Additionally, the extract significantly prevented the gastric mucosal injury induced by ischemia-reperfusion (PR) in rats when given orally at doses of 0.25 and 0.50 g/kg/day for 3 consecutive days (p<0.05; n=7). However, this effect was not found when the higher doses (1 and 2 g/kg/day) of the extract were tested. In conclusion, these results indicate that the MA leaf extract possesses the cytoprotective activity against free radical-induced Citarinostat cell injury. Therefore, when given at the appropriate dose range, the mulberry leaf may potentially be used as a food supplement in patients with certain diseases in which the oxidative stress-induced cellular injury is pathologically involved.”
“Background:The detection of a 14-3-3 elevated level in cerebrospinal fluid (CSF) is a part of the diagnostic criteria
for Crenigacestat price probable sporadic Creutzfeldt-Jakob disease (sCJD), as defined by the WHO. However, some pathological conditions associated with acute neuronal damage may result in a positive 14-3-3 test and thereby reduce test specificity in sCJD. Objective: Desmoplakin has been previously identified as up-regulated CSF protein in sCJD and these studies aimed to investigate its diagnostic utility and compare it with two known CSF markers, 14-3-3 and tau. Methods and Results: We tested CSF levels of 14-3-3, tau and desmoplakin in 58 sCJD patients and 81 control patients including 45 cases with an elevated 14-3-3 level due to other disease than sCJD. We detected an elevated CSF level of desmoplakin in 78%
learn more of the sCJD patients, while 14-3-3 (88%) and tau (91%) showed a higher positive rate. However, the false positive rate of newly tested desmoplakin was significantly lower in comparison to 14-3-3 and tau, and it accounted for only 11% versus 56% and 35%, respectively. Further reduction of false positive rates was achieved by combination of elevated tau level with a positive desmoplakin test. Moreover, in the non-sCJD group, desmoplakin level did not correlate with the level of both above-mentioned CSF markers, whereas a clear correlation was observed in the sCJD group. Conclusion: Desmoplakin showed a low positive rate accompanied by a very low false positive rate. Thus, we conclude that desmoplakin is a promising candidate for supportive CSF marker to rule out 14-3-3 false positive cases in sCJD differential diagnosis. Copyright (C) 2011 S. Karger AG, Basel”
