Objectives: A deficiency in superoxide dismutase (SOD) activity in preeclamptic placentas can lead to an excess of superoxide radicals and may be responsible for the development and the severity of preeclampsia (PE).
Design: Our studies were undertaken in order to determine placental SOD activity and to investigate their association with the development and the severity of PE.
Materials And Methods: The activity of SOD was determined using a spectrophotometric method in 22 placentas from normal term pregnancies (group K), 24 placentas from pregnancies complicated by severe PE (group PE), and 21 placentas from pregnancies complicated by severe PE and intrauterine growth retardation (IUGR) (group PEI).
Results: Mean activity of SOD (MSOD) in 45 preeclamptic placentas 3.89 +/- 1.32 (M +/- SD) was significantly lower (P = 0.008) as compared to MSOD in the group K (6.75 +/- 1.96). MSOD in the PEI group (3.5 +/- 1.29) was significantly lower (P = 0.03) as compared to MSOD in the group K. MSOD in the PE group (4.23 +/- 1.25) was lower than MSOD in the group K, but this difference was not statistically significant (P = 0.11). MSOD in the group PEI was lower as compared to MSOD in the PE group, however this difference was not statistically significant (P = 0.23).
Conclusions: The studies revealed decreased SOD activity in preeclamptic placentas in comparison to normal placentas.

Objective: To evaluate the responsiveness of three cone-beam computed tomography (CBCT) transverse analyses (University of the Pennsylvania [UPenn] analysis, Boston University analysis and Yonsei University [YU] analysis).
Materials And Methods: A consecutive cohort sample of patients was retrospectively reviewed for eligibility. CBCT records before treatment (T0) and immediately after maxillary expansion (T1) of 71 patients receiving tooth-supported rapid maxillary expansion (RME) and 57 patients receiving mini-screw-assisted RME (MARME) were finally analyzed.

Numerous studies have been investigated the toxic effects of silver nanoparticle (Ag-NPs) on algae; however, little attention has been paid to the defense pathways of algae cells to Ag-NPs. In the study, Chlamydomonas reinhardtii (C. reinhardtii) was selected as a model organism to investigate the defense mechanisms to Ag-NPs exposure.

Background: Cultural competency or the ongoing capacity of health care systems to provide for high-quality care to diverse patient populations (National Quality Forum, 2008) has been proposed as an organizational strategy to address disparities in quality of care, patient experience, and workforce representation. But far too many health care organizations still do not treat cultural competency as a business imperative and driver of strategy.
Purposes: The aim of the study was to examine the impact of a systematic, multifaceted, and organizational level cultural competency initiative on hospital performance metrics at the organizational and individual levels.

Background: Oxidative stress has been reported as a key pathogenic factor in many human liver diseases and in experimental models of cirrhosis related to hepatotoxin administration. The aim of this study was to verify the hypothesis that prehepatic portal hypertension aggravates the enterohepatic redox imbalance in thioacetamide-cirrhotic rats.
Materials And Methods: Wistar male rats were used: Control (n=9); rats with prehepatic portal hypertension by triple partial portal vein ligation (TPVL; n=9); thioacetamide-cirrhotic rats (TAA; n=9) and TPVL-rats associated to TAA administration (TPVL+TAA; n=9).
