A continuous isoelectric electroencephalogram reflects an interruption of endogenously-generated activity in cortical networks and systematically results in a complete dissolution of conscious processes. This electro-cerebral inactivity occurs during various brain disorders, including hypothermia, drug intoxication, long-lasting anoxia and brain trauma. It can also be induced in a therapeutic context, following the administration of high doses of barbiturate-derived compounds, to interrupt a hyper-refractory status epilepticus...

The efficacy of nivolumab is greater than that of other anti-melanoma drugs, so nivolumab-based combined therapies that enhance anti-tumor immune responses in patients with metastatic melanoma are of great interest to dermato-oncologists. As we have previously reported, IFN-β enhances the anti-tumor immune response of anti-PD-1 antibodies against B16F10 melanoma in vivo. To explore the potential of this property of IFN-β as part of a combination therapy for the treatment of metastatic melanoma patients, we performed a phase 1 trial, using a traditional rule-based 3 + 3 design, on patients with advanced melanoma...

BACKGROUND/AIMS: Recent studies provided compelling evidence that stimulation of the calcium sensing receptor (CaSR) exerts direct renoprotective action at the glomerular podocyte level. This protective action may be attributed to the RhoA-dependent stabilization of the actin cytoskeleton. However, the underlying mechanisms remain unclear. METHODS: In the present study, an immortalized human podocyte cell line was used. Fluo-3 fluorescence was utilized to determine intracellular Ca2+ concentration ([Ca2+]i), and western blotting was used to measure canonical transient receptor potential 6 (TRPC6) protein expression and RhoA activity...

Although the eukaryotic translation initiation factor 4E (eIF4E) has been shown to be critically involved in the transformation and progression of various tumors, little is known about the role of eIF4E in retinoblastoma. In this work, we report that ribavirin, a pharmacologic inhibitor of eIF4E function, effectively targets retinoblastoma and angiogenesis. Ribavirin treatment dose-dependently blocked the growth and stimulated apoptosis in various retinoblastoma cell lines, with IC50 values that are within the clinically achievable range...

BACKGROUND: Nutritional rehabilitation in anorexia nervosa (AN) is impeded by fear of food, eating and change leading to treatment resistance. Oxytocin (OT) exerts prosocial effects and modulates trust, fear, anxiety and neuroplasticity. The current placebo-controlled RCT examined the effects of intranasal oxytocin (IN-OT) in AN. The aim was to ascertain whether repeated doses of IN-OT enhance treatment outcomes in AN. METHODS: AN patients self-administered 36 IU IN-OT or placebo daily for 4-6 weeks during hospital treatment...

Purpose: The lens is a radiosensitive organ. Any dose of cephalic irradiation can give rise to radiation-induced cataracts. Contrary to other forms of radiotherapy, proton therapy (PT) can spare all or part of the lens due to accurate dose deposition. We investigated whether a lens-sparing approach was relevant to avoid cataracts in uveal melanoma patients. Methods: Patients were referred for PT from onco-ophthalmologists of private and academic institutions. Patients without preexisting cataracts or implants were entered in a prospective database...

Purpose: Fibroblast activation may play an important role in pterygium progression. Synthetic peroxisome proliferator-activated receptor γ (PPAR-γ) ligands have been shown to be effective antifibrotic agents against transforming growth factor β1 (TGF-β1) induced fibrosis in several tissues. We aimed to investigate the antifibrotic effects of the PPAR-γ ligand rosiglitazone in pterygium fibroblasts and the underlying mechanisms. Methods: Profibrotic activation was induced by TGF-β1 in primary cultured human pterygium fibroblasts and the effect of rosiglitazone treatment on α-smooth muscle actin (α-SMA), and extra cellular matrix proteins synthesis was detected by western blotting, real-time PCR, immunostaining, and flow cytometry...

Microglia activation and associated inflammatory response are involved in the pathogenesis of different neurodegenerative diseases. We have reported that Notch-1 and NF-κB/p65 signalling pathways operate in synergy in regulating the production of proinflammatory mediators in activated microglia. In the latter, there is also evidence by others that glycogen synthase kinase 3β (GSK-3β) mediates the release of proinflammatory cytokines but the interrelationships between the three signalling pathways have not been fully clarified...

Reelin is a large glycoprotein with a dual role in the mammalian brain. It regulates the positioning and differentiation of postmitotic neurons during brain development and modulates neurotransmission and memory formation in the adult brain. Alterations in the Reelin signaling pathway have been described in different psychiatric disorders. Reelin mainly signals by binding to the lipoprotein receptors Vldlr and ApoER2, which induces tyrosine phosphorylation of the adaptor protein Dab1 mediated by Src family kinases (SFKs)...

Chemotherapy is a vital therapeutic strategy for castration-resistant prostate cancer (CRPC). We have previously shown that NSC606985 (NSC), a camptothecin (CPT) analog, induced cell apoptosis via interacting with topoisomerase I (Topo I) in prostate cancer cells. In the present study, the effect and mechanism of CPT analogs in LAPC4 cells were investigated. LAPC-4 cells were treated with NSC, CPT, and topotecan. Cell proliferation, apoptosis, and protein kinase Cδ (PKCδ) subcellular activation were measured at different doses and time-points, with or without PKCδ inhibition or knockdown of PKCδ expression...
