Non-shockable rhythms represent an increasing proportion of reported cases of out-of-hospital cardiac arrest but with an associated poor prognosis. In the present study, we investigated the effects of hydrogen inhalation on cardiac and neurological function after cardiopulmonary resuscitation and compared the therapeutic benefit with hypothermia in an asphyxial rat model of cardiac arrest.', 'Cardiopulmonary resuscitation was initiated after 5 min of untreated asphyxial cardiac arrest. Animals were randomly assigned to three experimental groups immediately after successful resuscitation: ventilation with 2% hydrogen/98% oxygen under normothermia (H2 inhalation), ventilation with 2% nitrogen/98% oxygen under normothermia (Control), and ventilation with 2% nitrogen/98% oxygen under hypothermia (TH). Mixed gas inhalation continued for 1 h while hypothermia continued for 2\u200ah. Animals were observed up to 96\u200ah for assessment of survival and neurologic recovery.', 'No statistical differences in baseline measurements were observed among groups and all the animals were successfully resuscitated. Serum cardiac troponin T and S100B measured during earlier post-resuscitation period were markedly reduced in both H2 inhalation and hypothermic groups. However, significantly better left ventricular ejection fraction, cardiac work, and neurological deficit score were observed in the H2 inhalation group. Ninety-six hours survival rate was significantly higher in the H2 inhalation group (75.0%), either compared with TH (45.8%) or compared with Control (33.3%). But there was no statistical difference between TH and Control.

Our previous in-vivo and in-vitro studies demonstrated that inflammation accelerated the progression of atherosclerosis via the dysregulation of the low-density lipoprotein receptor (LDLr) pathway. The current study aimed to investigate the effects and their underlying mechanisms of inflammation on lipid accumulation in the radial arteries of endstage renal disease (ESRD) patients with arteriovenostomy.', '30 ESRD patients with arteriovenostomy were included. The patients were divided into two groups based on their plasma levels of C-reactive protein: a control (n = 16) and an inflamed group (n = 14). The expression of tumor necrosis factor-alpha (TNF-alpha) and monocyte chemotactic protein-1 of the radial arteries were increased in the inflamed group. Foam cell formation and lipid droplet accumulation were examined by hematoxylin and eosin (H & E) and Oil Red O staining. Intracellular cholesterol trafficking-related proteins were examined by immunohistochemistry and immunofluorescent staining.', 'There was significant lipid accumulation in the radial arteries of the inflamed group compared with the control. Further analysis demonstrated that this accumulation was correlated with the increased protein expression of LDLr, sterol regulatory element-binding protein-2 (SREBP-2), and SREBP cleavageactivating protein (SCAP). Confocal microscopy showed that inflammation enhanced the translocation of SCAP escorting SREBP-2 from the endoplasmic reticulum to the Golgi, thereby activating LDLr gene transcription. Interestingly, upregulated LDLr expression was positively associated with the increased protein expression of mammalian target of rapamycin (mTOR), which had enhanced coexpression with SREBP-2. This finding suggests that the activation of mTOR may be involved in LDLr pathway disruption through the upregulation of SREBP-2 expression.

Sublethal doses of photon irradiation (IR) are suspected to increase tumor cell migration and support locoregional recurrence of disease, which has already been shown in other cell lines. This manuscript describes the effect of photon and carbon-ion IR on WHO class I meningioma cell migration and provides an approach to the underlying cellular mechanisms.', "Meningioma cells were gained operatively at the university hospital in Homburg/Saar, Germany. For migration, membranes (8-µm pore sizes) were coated with collagen I, with collagen IV, and with fibronectin. Cells were analyzed in migration experiments with or without serum stimulation, with or without photon and carbon IR 24\xa0h prior to experiments, and with or without integrin antibodies. Fluorescence-activated cell sorting (FACS) analyses of the integrins ανβ1, ανβ3, and ανβ5 were performed without IR and 6, 12 and 24\xa0h after IR. Enzyme-linked immunosorbent assay (ELISA) analyses of matrix metalloproteinases (MMP)-2 and MMP-9 were realized with and without IR after cells were cultured on collagen I, collagen IV, or fibronectin for 24\xa0h. Cells and supernatants for FACS and ELISA were stored at -\u200918\u2009°C. The significance level was set at 5\u2009% using both Student's t test and two-way ANOVA.", 'Migration of meningioma cells was serum-inducible (p\u2009<\u20090.001). It could be increased by photon IR (p\u2009<\u20090.02). The integrins ανβ1 and ανβ5 showed a 21 and 11\u2009% higher expression after serum stimulation (not significant), respectively, and ανβ1 expression was raised by 14\u2009% (p\u2009=\u20090.0057) after photon IR. Antibody blockage of the integrins ανβ1 and ανβ5 inhibited serum- and photon-induced migration. Expression of MMP-2 and MMP-9 remained unchanged after both IR and fetal bovine serum (FBS). Carbon-ion IR left both integrin expression and meningioma cell migration unaffected.
