The (pro)renin receptor [(P)RR, ATP6AP2] is a multifunctional transmembrane protein that activates local renin-angiotensin systems, but also interacts with Wnt pathways and vacuolar H(+) -ATPase (V-ATPase) during organogenesis. The aim of this study was to characterize the role of ATP6AP2 in the cell cycle in more detail. ATP6AP2 down-regulation by siRNA in renal As4.1 cells resulted in a reduction in the rate of proliferation and a G0/G1 phase cell cycle arrest. We identified a number of novel target genes downstream of ATP6AP2 knock-down that were related to the primary cilium (Bbs-1, Bbs-3, Bbs-7, Rabl5, Ttc26, Mks-11, Mks-5, Mks-2, Tctn2, Nme7) and the cell cycle (Pierce1, Clock, Ppif)...

BACKGROUND: To know the objective methods of the effects of the brachial plexus block, we studied the changes in percutaneous oxygen pressure (tcPO₂) with the hypothesis that tcPO₂ increases significantly on the blocked arm in comparison with the non-blocked arm, a phenomenon which is connected with vasodilation following the brachial plexus block. METHODS: Fifteen patients scheduled for upper extremity surgery, aged 20 to 70 years, with ASA physical status I or II were included...

Platelets are crucial to the hemostatic response. Their role in coagulation is well documented and they have been considered for some time to promote resistance of thrombi to fibrinolysis. Platelets confer resistance to lysis by promoting clot retraction of the immediate fibrin network and through release of plasminogen activator inhibitor-1 from their α-granules. However, recent developments in the field indicate that the role of platelets in fibrinolysis is much more diverse. Indeed, novel studies suggest that platelets form different subpopulations upon activation that play varied roles in regulating hemostasis...

The primary purpose of this study was to assess the serum levels of homocysteine (HCY) at admission to the presence of post-stroke depression (PSD). From September 2014 to December 2015, first-ever acute ischemic stroke patients within the first 24 h after stroke onset were consecutively recruited and followed-up for 3 months. Based on the symptoms, diagnoses of depression were made in accordance with DSM-IV criteria for depression. By the time of 3 month after stroke, 238 had finished the follow-up and included in our study...

Paraquat can result in dysfunction of multiple organs after ingestion in human. However, the mechanisms of nucleotide-binding domain and leucine-rich repeat containing protein 3 (NLRP3) inflammasome activation in acute kidney injury have not been clearly demonstrated. The aim of this study was to determine the effect of NLRP3 inflammasome activation and its regulation by nuclear factor-kappa B (NF-κB) and death-associated protein kinase (DAPK). Male Wistar rats were treated with intraperitoneal injection of paraquat at 20 mg/kg, and NF-κB inhibitor BAY 11-7082 was pretreated at 10 mg/kg 1 h before paraquat exposure...

Macrocyclic glycopeptide based liquid chromatography stationary phases are known for their highly selective peptide separations. Fast and ultrafast (t R < 1 min) high-efficiency separations were achieved with superficially porous particle (SPP)-based stationary phases. Separations of pharmaceutically important classes of peptides such as enkephalins and bradykinins have been achieved in less than 5 min in isocratic elution modes. Selectivity for peptides structurally similar to one another was increased with use of teicoplanin-based stationary phases compared with commercial C18 stationary phases...

Climate change is likely to be one of the most important factors affecting our future food security. To mitigate negative impacts, we will require our crops to be more genetically diverse. Such diversity is available in crop wild relatives (CWRs), the wild taxa relatively closely related to crops and from which diverse traits can be transferred to the crop. Conservation of such genetic resources resides within the nation where they are found; therefore, national-level conservation recommendations are fundamental to global food security...

PURPOSE: Electromagnetic (EM) catheter tracking has recently been introduced in order to enable prompt and uncomplicated reconstruction of catheter paths in various clinical interventions. However, EM tracking is prone to measurement errors which can compromise the outcome of the procedure. Minimizing catheter tracking errors is therefore paramount to improve the path reconstruction accuracy. METHODS: An extended Kalman filter (EKF) was employed to combine the nonlinear kinematic model of an EM sensor inside the catheter, with both its position and orientation measurements...

Clinical studies demonstrated a positive correlation between hypertension and cognitive decline. Beneficial effects of angiotensin II receptor blockers on cognitive functions have also been reported earlier; however, its role in chronic neuroinflammation-induced memory impairment in the hypertensive state is not well understood. Therefore, in the present study, we investigated the effect of angiotensin II receptor blockers on memory impairment induced by lipopolysaccharide (LPS) in spontaneously hypertensive rats (SHRs)...

E6ap is a known transcriptional coregulator for estrogen receptor alpha (Er, Erα) in the presence of estrogen. Protein kinase A (PKA) contains two regulatory subunits derived from four genes. Recent evidence demonstrates that PKA regulates E6ap activity. Data generated in our lab indicated estrogen dependent regulation of Pkar2a levels. Our project sets to investigate a possible feedback mechanism constituting of Erα and E6ap transcriptional regulation of Pkar2a expression. Western blot evaluated protein regulation correlations with E2 in mouse neuroblastoma lines...

Patients scheduled for primary care appointments often cancel or no show. For diabetic patients, nonattendance can affect continuity of care and result in higher emergency department (ED) and hospital use. Nonattendance also impacts appointment scheduling, patient access, and clinic work load. While no show has received significant attention, little research has addressed the prevalence and impact of appointment cancellation. Data on 46,710 appointments for 7586 adult diabetic patients was used to conduct a prospective cohort study examining primary care appointment behavior...

The Jimpy mouse illustrates the importance of interactions between astrocytes and oligodendrocytes. It has a mutation in Plp coding for proteolipid protein and DM20. Its behavior is normal at birth but from the age of ~2 weeks it shows severe convulsions associated with oligodendrocyte/myelination deficits and early death. A normally occurring increase in oxygen consumption by highly elevated K(+) concentrations is absent in Jimpy brain slices and cultured astrocytes, reflecting that Plp at early embryonic stages affects common precursors as also shown by the ability of conditioned medium from normal astrocytes to counteract histological abnormalities...

The present study was aimed to evaluate the neuroprotective effects of NBP in the mice models of TBI, as well as the possible role of Nrf2-ARE pathways in the assumptive neuroprotection. In mice,a modified Marmarou's weight-drop model was employed to induce TBI. ICR mice were randomly assigned to four experimental groups: sham, TBI, TBI+vehicle(V) and TBI+NBP. NBP (100 mg/kg) was administered via an intraperitoneal (i.p.) injection at 1 h following TBI. The administration of NBP significantly ameliorated the effects of the brain injury, including neurological deficits, brain water content, and cortical neuronal apoptosis...

Interferon-α (IFNα) was the first effective drug therapy for hairy cell leukemia (HCL). Nowadays, it is used as an alternative treatment in selected patients. Due to unlimited treatment time, monitoring and early prediction of response are important. Moreover, IFNα is used in the therapy of chronic hepatitis C, where a single nucleotide polymorphism of interleukin-28B gene (IL28B) correlates with therapy response. The role of this polymorphism in therapy response of IFNα-treated patients with HCL is unknown...

The CIBMTR chronic graft-versus-host disease (cGVHD) risk score can be refined and improved for better prognostic stratification. Three hundred and seven consecutive patients diagnosed with cGVHD by the NIH consensus criteria were retrospectively reviewed and had the CIBMTR risk score applied and analyzed. The CIBMTR risk score was successfully validated in our cohort (n = 307). The 3-year overall survival (OS) rates in each risk group (RG) were 82.5 ± 11.3% (RG1), 79.4 ± 3.0% (RG2), 71.8 ± 6.3% (RG3), and 27...

Hyperglycemia and mitochondrial ROS overproduction have been identified as key factors involved in the development of diabetic nephropathy. This has encouraged the search for strategies decreasing glucose levels and long-term improvement of redox status of glutathione, the main antioxidant counteracting mitochondrial damage. Previously, we have shown that avocado oil improves redox status of glutathione in liver and brain mitochondria from streptozotocin-induced diabetic rats; however, the long-term effects of avocado oil and its hypoglycemic effect cannot be evaluated because this model displays low survival and insulin depletion...
