BACKGROUND Several studies of spontaneous intracerebral hemorrhage(SICH)patients have shown apoptotic changes in brain samples after hematoma ***,there have been no data on the association between blood concentrations of soluble fas(sFas)(the main surface death receptor of the extrinsic apoptosis pathway)and the prognosis of spontaneous intracranial hypotension(SIH)*** To determine whether there is an association between blood sFas concentrations and SICH patient *** We included patients with severe and supratentorial *** was defined as having Glasgow Coma Scale<*** determined serum sFas concentrations at the time of severe SICH *** We found that non-surviving patients(n=36)compared to surviving patients(n=39)had higher ICH score(P=0.001),higher midline shift(P=0.004),higher serum sFas concentrations(P<0.001),and lower rate of early hematoma evacuation(P=0.04).Multiple logistic regression analysis showed an association between serum sFas concentrations and 30-d mortality(odds ratio=1.070;95%confidence interval=1.014-1.129;P=0.01)controlling for ICH score,midline shift,and early hematoma *** The association of blood sFas concentrations and SICH patient mortality is a novel finding in our study.

Background Protamination and condensation of sperm chromatin as well as DNA integrity play an essential role during fertilization and embryo *** some mammals,like pigs,ejaculates are emitted in three separate fractions:pre-sperm,sperm-rich(SRF)and post sperm-rich(PSRF).These fractions are known to vary in volume,sperm concentration and quality,as well as in the origin and composition of seminal plasma(SP),with differences being also observed within the SRF ***,whether disparities in the DNA integrity and chromatin condensation and pro-tamination of their sperm exist has not been *** This study determined chromatin protamination(Chromomycin A3 test,CMA_(3)),condensation(Dibromobi-mane test,DBB),and DNA integrity(Comet assay)in the pig sperm contained in the first 10 m L of the SRF(SRF-P1),the remaining portion of the sperm-rich fraction(SRF-P2),and the post sperm-rich fraction(PSRF).While chromatin protamination was found to be similar between the different ejaculate fractions(P>0.05),chromatin condensation was seen to be greater in SRF-P1 and SRF-P2 than in the PSRF(P=0.018 and P=0.004,respectively).Regarding DNA integrity,no differences between fractions were observed(P>0.05).As the SRF-P1 has the highest sperm concentra-tion and ejaculate fractions are known to differ in antioxidant composition,the oxidative stress index(OSi)in SP,calcu-lated as total oxidant activity divided by total antioxidant capacity,was tested and confirmed to be higher in the SRF-P1 than in SRF-P2 and PSRF(0.42±0.06 vs.0.23±0.09 and 0.08±0.00,respectively;P<0.01);this index,in addition,was observed to be correlated to the sperm concentration of each fraction(Rs=0.973;P<0.001).Conclusion While sperm DNA integrity was not found to differ between ejaculate fractions,SRF-P1 and SRF-P2 were observed to exhibit greater chromatin condensation than the *** could be related to the OSi of each fraction.

The high voltage required to overcome the thermodynamic threshold and the complicated kinetics of the water splitting reaction limit the efficiency of single semiconductor-based photoelectrochemistry.A semiconductor/solar cell tandem structure has been theoretically demonstrated as a viable path to achieve an efficient direct transformation of sunlight into chemical energy.
