Abstract
Posterior cerebral aneurysms are rare vascular lesions and usually present as non-saccular or dissecting in nature. We present a retrospective review of our experience in the deliberate parent artery occlusion of posterior cerebral artery (PCA) aneurysms.From June 2006 to June 2010, 12 patients (seven men, five women) with posterior cerebral artery non-saccular aneurysms presented to our department and were treated by parent artery occlusion. There were eight (66.7%) aneurysms located at the P2 segment, two (16.7%) at the P2-3 junction, one (8.3%) at the P1-2 junction and one (8.3%) at the P3 segment. Ten of the 12 patients were treated by aneurysm together with parent artery occlusion and two were treated by proximal occlusion.The procedure was technically successful in all cases. Angiography was performed immediately after the procedure in all patients and showed occlusion of the parent vessel with no filling of the aneurysm. Only one patient (8.3%) developed procedure-related transient hemianopsia and recovered within one month. The other 11 patients showed no additional neurological symptoms after procedure. Deliberate parent artery occlusion by detachable coils appears to be well tolerated for P2 or distal segment of PCA in our limited case series. We propose that this technique could be a good treatment option in treating non-saccular aneurysms in this location.

Abstract
UNLABELLED The scientific literature through 2005 on the effects of ventilation rates on health in indoor environments has been reviewed by a multidisciplinary group. The group judged 27 papers published in peer-reviewed scientific journals as providing sufficient information on both ventilation rates and health effects to inform the relationship. Consistency was found across multiple investigations and different epidemiologic designs for different populations. Multiple health endpoints show similar relationships with ventilation rate. There is biological plausibility for an association of health outcomes with ventilation rates, although the literature does not provide clear evidence on particular agent(s) for the effects. Higher ventilation rates in offices, up to about 25 l/s per person, are associated with reduced prevalence of sick building syndrome (SBS) symptoms. The limited available data suggest that inflammation, respiratory infections, asthma symptoms and short-term sick leave increase with lower ventilation rates. Home ventilation rates above 0.5 air changes per hour (h(-1)) have been associated with a reduced risk of allergic manifestations among children in a Nordic climate. The need remains for more studies of the relationship between ventilation rates and health, especially in diverse climates, in locations with polluted outdoor air and in buildings other than offices. PRACTICAL IMPLICATIONS Ventilation with outdoor air plays an important role influencing human exposures to indoor pollutants. This review and assessment indicates that increasing ventilation rates above currently adopted standards and guidelines should result in reduced prevalence of negative health outcomes. Building operators and designers should avoid low ventilation rates unless alternative effective measures, such as source control or air cleaning, are employed to limit indoor pollutant levels.

Abstract
Based on the importance of exercise and crucial role of liver in metabolism, the aim of this study was to determine whether the expression of peroxisome proliferator-activated receptor (PPAR)-α, γ and adiponectin receptor 2 in OLETF rat liver were altered in conjunction with improved metabolism with exercise training. OLETF rats were randomly assigned to 2 groups: sedentary control group (n=26), and long-term exercise-trained group (n=26). Full data were available on 32 OLETF rats (16 for each group). Adiponectin, glucose, insulin, triglyceride and cholesterol were assessed. Livers were taken to determine the expression of PPAR-α, γ and adiponectin receptor 2. Compared with sedentary control group, fasting glucose (9.38 ± 2.99 mmol/L vs. 7.32 ± 1.76 mmol/L, P<0.05), triglyceride (1.73 ± 0.34 mmol/L vs. 0.89 ± 0.12 mmol/L, P<0.05) and cholesterol (4.41 ± 0.75 mmol/L vs. 2.13 ± 0.32 mmol/L, P<0.05) were substantially reduced after exercise, which significantly correlated with increased PPAR-α (P<0.05) in liver. The expression of PPAR-α upstream and target genes, including hepatocyte nuclear factor-4 (HNF4), carnitine palmitoyl transferase 1 (CPT-1), catalase (CAT) and ATPbinding cassette transporter A1 (ABCA1) also increased significantly. Therefore, our findings suggest that increased PPAR-α expression in OLETF rats liver is a contributory factor to the exercise-related improvements in whole-body metabolism.

Abstract
A critical function of cells is the maintenance of their genomic integrity. A family of phosphoinositide-3-kinase-related protein kinases, which includes ataxia telangiectasia mutated (ATM) and ataxia telangiectasia and Rad3 related (ATR) kinases, play key roles in sensing DNA damage. ATM and ATR were demonstrated in the cleavage stages of mouse embryo development. Genotoxic stress was imposed by exposure to ultraviolet (UV) radiation (causes DNA strand breaks) or cisplatin (causes strand cross-links). UV irradiation or cisplatin treatment of 2-cell embryos in the G(2) phase of the cell cycle caused DNA damage as defined by increased phosphorylation of the H2A histone family, member X (H2AFX; previously H2AX) variant. UV irradiation caused a stable G(2)-M arrest, and cisplatin treatment allowed progression through mitosis followed by activation of a G(1)-S checkpoint. Both checkpoints were transformation-related protein 53-independent. Caffeine (inhibits both ATM and ATR), but not KU55933 (ATM-selective inhibitor), reversed the G(2)-M block induced by UV, inferring a primary role for ATR in sensing this form of DNA damage. Caffeine and KU55933 were equally effective in reversing the cisplatin-induced G(1)-S block, implicating ATM as the primary sensing enzyme. Breaching of either checkpoint by treatment with caffeine or KU55933 allowed embryos to progress through several further cell cycles, yet none developed to blastocysts. The results show, to our knowledge for the first time, that the G(2)-M and G(1)-S cell-cycle checkpoints in the early embryo are differentially regulated by ATM and ATR in response to genotoxic stress and that they act as an initial point for containment of genomic damage. Under conditions of extensive or persistent DNA damage, the demise of the embryo is the ultimate method of protecting genomic integrity.

Abstract
This study assessed cardiac diastolic dysfunction (DD) in HIV-infected subjects without cardiovascular symptoms in China. Eighty-four HIV-infected patients without cardiovascular symptoms were recruited and compared with 30 HIV-negative control subjects. Cardiac DD was evaluated using echocardiography including tissue Doppler imaging. DD was detected in 47.6% of AIDS patients and 42.8% of HIV-positive patients, which was significantly higher than in HIV-negative controls. After logistic regression analysis, HIV infection was independently correlated with cardiac DD (P < 0.05). Among HIV-positive subjects, logistic regression analysis showed that zidovudine exposure was associated with higher prevalence of DD (P < 0.05). Asymptomatic cardiac DD was observed frequently in HIV-infected subjects. HIV infection itself and zidovudine exposure were correlated with a higher prevalence of cardiac DD.

Abstract
OBJECTIVES The purpose of this study was to correlate 2-dimensional magnetic resonance (MR) measurements of lateral ventricular width and 3-dimensional measurements of lateral ventricular and supratentorial parenchymal volumes to postnatal outcomes in fetuses with ventriculomegaly. METHODS A total of 307 fetuses (mean gestational age, 26.0 weeks; range, 15.7-39.4 weeks) had MR volumetry after referral for ventriculomegaly. Fetuses were grouped into those with (n = 114) and without (n = 193) other central nervous system (CNS) anomalies. Pregnancy and postnatal neurodevelopmental outcomes up to 3 years of age were obtained. A subgroup analysis was performed excluding fetuses with other CNS anomalies. Logistic regression analysis was performed to assess which measurement was most predictive of outcomes. RESULTS There were 50 terminations, 2 stillbirths, and 255 live births. Seventy-five cases were lost to follow-up. Among 180 live-born neonates with follow-up, 140 had abnormal and 40 had normal outcomes. Atrial diameter (P < .0001), frontal horn diameter (P < .0001), and ventricular volume (P = .04) were predictive of live birth, with 92% specificity at 60% sensitivity. Among fetuses without other CNS anomalies, 180 of 193 pregnancies (93%) resulted in live deliveries, with atrial diameter (P < .0001), frontal horn diameter (P = .003), and ventricular volume (P = .008) associated with live birth and atrial diameter having the highest specificity (>99% at 60% sensitivity). Parenchymal volume was not associated with normal or abnormal outcomes (either live birth versus death or normal versus abnormal neurodevelopmental outcome). Among live-born neonates, no age-adjusted threshold for any of the measurements reliably distinguished between normal and abnormal neurodevelopmental outcomes. CONCLUSIONS Ventricular volume and diameter, but not parenchymal volume, correlate with live birth in fetuses with ventriculomegaly. However, once live born, neither 2- nor 3-dimensional measurements can distinguish a fetus that will have a normal outcome.
