Given a passage, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

Enhanced activation of the mineralocorticoid receptors (MRs) in cardiovascular tissues increases oxidative stress, maladaptive immune responses, and inflammation with associated functional vascular abnormalities. We previously demonstrated that consumption of a Western diet (WD) for 16 weeks results in aortic stiffening, and that these abnormalities were prevented by systemic MR blockade in female mice. However, the cell-specific role of endothelial cell MR (ECMR) in these maladaptive vascular effects has not been explored.', 'We hypothesized that specific deletion of the ECMR would prevent WD-induced increases in endothelial sodium channel activation, reductions in bioavailable nitric oxide, increased vascular remodeling, and associated increases in vascular stiffness in females.', 'Four-week-old female ECMR knockout and wild-type mice were fed either mouse chow or WD for 16 weeks. WD feeding resulted in aortic stiffness and endothelial dysfunction as determined in vivo by pulse wave velocity and ex vivo by atomic force microscopy, and wire and pressure myography. The WD-induced aortic stiffness was associated with enhanced endothelial sodium channel activation, attenuated endothelial nitric oxide synthase activation, increased oxidative stress, a proinflammatory immune response and fibrosis. Conversely, cell-specific ECMR deficiency prevented WD-induced aortic fibrosis and stiffness in conjunction with reductions in endothelial sodium channel activation, oxidative stress and macrophage proinflammatory polarization, restoration of endothelial nitric oxide synthase activation.

Sigma-1 receptors are involved in the pathophysiological process of several neuropsychiatric diseases such as epilepsy, depression. Allosteric modulation represents an important mechanism for receptor functional regulation. In this study, we examined antidepressant activity of the latest identified novel and selective allosteric modulator of sigma-1 receptor 3-methyl-phenyl-2, 3, 4, 5-tetrahydro-1H-benzo[d]azepin-7-ol (SOMCL-668).', 'A single administration of SOMCL-668 decreased the immobility time in the forced swimming test (FST) and tailing suspended test in mice, which were abolished by pretreatment of sigma-1 receptor antagonist BD1047. In the chronic unpredicted mild stress (CUMS) model, chronic application of SOMCL-668 rapidly ameliorated anhedonia-like behavior (within a week), accompanying with the enhanced expression of brain-derived neurotrophic factor (BDNF) and phosphorylation of glycogen synthase kinase 3β (GSK3β) (Ser-9) in the hippocampus. SOMCL-668 also rapidly promoted the phosphorylation of GSK3β (Ser-9) in an allosteric manner in vitro. In the cultured primary neurons, SOMCL-668 enhanced the sigma-1 receptor agonist-induced neurite outgrowth and the secretion of BDNF.

Ex Input:
To assess whether zoledronic acid (ZOL) adds to the effect of combined androgen blockade (CAB) in patients with hormone-naive bone metastatic prostate cancer.', 'Patients were treated with either a combination of CAB (luteinizing hormone-releasing hormone agonist and bicalutamide) and ZOL (CAB-Z group) or CAB-alone (historical control patients, CAB-C group). ZOL was injected intravenously at 4 mg every 4 weeks. One hundred and five and 100 patients among 205 enrolled patients were assigned to the CAB-Z group and CAB-C group, respectively. The time to prostate-specific antigen (PSA) failure in patients in the CAB-Z group was compared to that in the CAB-C group. The primary end-point of the study was the time-to-PSA failure.', 'PSA and serum N-telopeptide of type I collagen (NTx) levels were examined before treatment and every 3 months after treatment. PSA failure occurred in 42 (40.0%) patients in the CAB-Z group and 48 (48.0%) patients in the CAB-C group. The biochemical recurrence-free rate was significantly lower in patients in the CAB-C group (p=0.004, by log-rank test). The categorical biopsy Gleason score pre-treatment serum NTx and treatment with ZOL were shown to be independent predictors of PSA failure-free survival time (p=0.040, p=0.005 and p=0.026, respectively).
