Oxidative stress and apoptosis in preeclampsia.

Abstract: We aimed to determine the oxidative stress and antioxidant status in preeclamptic placenta. Also, we investigated the apoptotic index of villous trophoblast and proliferation index of cytotrophoblasts. The study included 32 pregnant with preeclampsia and 31 normotensive healthy pregnant women. Malondialdehyde (MDA) and total antioxidant status (TAS) levels were measured in the placenta. For detection of apoptosis and proliferation in trophoblast, apoptosis protease activating factor 1 (APAF-1) and Ki-67 were used. Placental MDA levels in preeclamptic women were significantly higher than normal pregnancies (p = 0.002). There was no significant difference between the groups in the TAS levels of placenta (p = 0.773). Also, the apoptotic index in villous trophoblasts increased (p

Anomalous quartic ZZγγ couplings in γp collision at the LHC

Abstract: We investigate the constraints on the anomalous quartic $ZZ\ensuremath{\gamma}\ensuremath{\gamma}$ couplings through the process $pp\ensuremath{\rightarrow}p\ensuremath{\gamma}p\ensuremath{\rightarrow}p\ensuremath{\gamma}qZX$ at the LHC. Taking into consideration various forward detector acceptances and integrated LHC luminosities, we find 95% confidence level bounds on the anomalous coupling parameters. We show that the bounds on these couplings are at the order of ${10}^{\ensuremath{-}6}\text{ }\text{ }{\mathrm{GeV}}^{\ensuremath{-}2}$ which are about four orders of magnitude more restricted with respect to current experimental bounds.
