Both basic and clinical research support the use of tactile stimulation to rescue several neurobiobehavioral consequences that follow early life stress including. Here, using a translational rodent model of the neonatal intensive care unit (NICU), we tested the individual prophylactic potential of a variety of sensory interventions including tactile (brushing pups with a paint brush to mimic maternal licking), auditory (a simulated lactating rat dam heart beat), and olfactory (a series of aroma therapy scents) stimulation...

Exercising at the maximal lactate steady state (MLSS) results in increased but stable metabolic responses. We tested the hypothesis that even a slight increase above MLSS (10 W), by altering the metabolic steady-state, would reduce exercise performance capacity. Eleven trained men in our study performed: one ramp-incremental tests; two to four 30-min constant-load cycling exercise trials to determine the PO at MLSS (MLSSp ), and ten watts above MLSS (MLSSp+10 ), which were immediately followed by a time-to-exhaustion test; and a time-to-exhaustion test with no-prior exercise...

Dysfunction of mitochondrial activity is often associated with the onset and progress of neurodegenerative diseases. Membrane depolarization induced by Na+ influx increases intracellular Ca2+ levels in neurons, which upregulates mitochondrial activity. However, overlimit of Na+ influx and its prolonged retention ultimately cause excitotoxicity leading to neuronal cell death. To return the membrane potential to the normal level, Na+ /K+ -ATPase exchanges intracellular Na+ with extracellular K+ by consuming a large amount of ATP...

Pump thrombosis remains a serious complication of implantable ventricular assist device therapy and is associated with increased risk of morbidity and mortality. Optimal management strategies remain controversial and are guided largely by limited literature and expert opinion. Medical management of pump thrombosis, including the use of direct thrombin inhibitors, has been associated with mixed results. The purpose of this study is to report the outcomes associated with bivalirudin therapy in LVAD patients with suspected pump thrombosis...

We report here the identification of α1 Na/K-ATPase as a major regulator of the proto-oncogene Src kinase and the role of this regulation in control of Warburg effect and tumor growth. Specifically, we discovered Y260 in α1 Na/K-ATPase as a Src-specific phosphorylation and binding site and that Y260 phosphorylation is required for Src-mediated signal transduction in response to a number of stimuli including EGF. As such, it enables a dynamic control of aerobic glycolysis. However, such regulation appears to be lost or attenuated in human cancers as the expression of Na/K-ATPase α1 was significantly decreased in prostate, breast and kidney cancers, and further reduced in corresponding metastatic lesions in patient samples...

Patients with sickle cell disease (SCD) display puzzling inter-individual phenotypic heterogeneity, conceivably related to inherent differences in antioxidant protection, hemoglobin binding, bilirubin catabolism and methyl group handling. Therefore, we explored putative associations between clinically important phenotypic measures and functional polymorphisms within specific candidate genes encoding glutathione S-transferase, haptoglobin, uridine 5'-diphospho-glucuronosyltransferase 1A1, methyl tetrahydrofolate reductase, 5-methyltetrahydrofolate-homocysteine methyltransferase, and cystathionine beta-synthase...

Oxidative stress has been regarded as the leading mechanism of the hepatotoxicity of clofibrate (CF). To achieve multifunctional novel hypolipidemic agents with hypolipidemia, antioxidant, and ameliorating liver injury, clofibric acid derivative hydroxytyrosol-clofibrate (CF-HT) was synthesized by molecular hybridization. CF-HT exhibited significant hypolipidemia, reducing serum triglyceride (TG), total cholesterol (TC), and malonaldehyde (MDA) by 30%, 33%, and 29% in hyperlipidemic mice induced by Triton WR 1339...

Atherosclerosis is a chronic inflammatory disease involved in endothelial dysfunction. Pyroptosis is a pro-inflammatory form of cell death and plays pivotal roles in atherosclerosis. MicroRNAs (miRNAs) are implicated in atherosclerosis, however the mechanisms that underlie miR-30c-5p is required for endothelial cell pyroptosis remain elusive. In the present study, we probed the interaction of miR-30c-5p with forkhead box O3 (FOXO3) and investigated the effect of miR-30c-5p and FOXO3 on NLRP3 inflammasome and endothelial cell pyroptosis...

OBJECTIVE: Early hemorrhage control before the operating room is essential to reduce the significant mortality associated with traumatic injuries of the vena cava. Conventional approaches present logistical challenges on the battlefield or in the trauma bay. A retrievable stent graft would allow rapid hemorrhage control in the preoperative setting when endovascular expertise is not immediately available and without committing a patient to the limitations of current permanent stents. This study details a refined retrievable Rescue stent for percutaneous delivery that was examined in a porcine survival model of penetrating caval hemorrhage...

The application of iodinated contrast medium has become a risk factor for metformin-associated lactic acidosis (MALA), which leads to the accumulation of metformin in vivo is one of the principal reasons for MALA. However, the molecular mechanism of the adverse event is not yet clear. In this study, iohexol injection was used as a model drug. The contrast agent acute kidney injury rat model, in vivo rat pharmacokinetic study, kidney slices and HK-2 cells were performed to elucidate the pharmacokinetic molecular mechanism of accumulation of metformin caused by contrast-induced nephropathy (CIN)...

An imbalance between excitatory and inhibitory neurotransmitters is known to induce neuronal excitotoxicity which is a major cause of neurodegenerative disorders. Excessive glutamate concentration leads to the neuronal death by increasing oxidative stress and affecting the apoptotic signaling pathway. We investigated the anti-excitotoxic effects and associated working mechanisms of 30% ethanol extract of Aquilariae Lignum (ALE) against hippocampal neuronal death by glutamate. HT22 cells were treated with glutamate (20 mM) for 24 h following pretreatment with ALE (5, 10, 25 μg/mL)...

The eusocial Damaraland mole-rat (Fukomys damarensis) represents an extreme example of reproductive skew, in that reproduction is completely blocked in female subordinate group members. It is thought that in these animals normal GnRH secretion from the hypothalamus is disrupted. Prolactin, a peptide hormone secreted from the anterior pituitary gland, has been implicated in a wide variety of functions. Well documented in rodents is its role in mediating lactational infertility. Elevated circulating prolactin levels, such as during lactation, are associated with reduced GnRH release into the portal blood and with a reduction in the frequency and amplitude of LH pulses...
