Results: Higher total testosterone concentrations were found in alcoholics on the second day of abstinence, as compared to controls (7.1 ± 1.9 vs 5.6 ± 1.4 ng/ml) and throughout the whole observation period. Correspondingly, free testosterone concentrations were increased over control levels on day 2 (40.0 ± 12.1 vs 29.7 ± 8.1 pg/ml) and stayed elevated in the presence of augmented concentrations of LH [4.5 U/l (range 1.6–9.5 U/l) vs 2.0 U/l (range 0.8–8.1 U/l)] for up to 127 days of strictly controlled abstinence.

Although deficits in HC-related functions are among the most commonly reported cognitive sequelae in alcoholism, little and conflicting information is available concerning regeneration upon abstinence. The present study has been designed to evaluate (i) the frequency of measurable dysfunction in so called HC tests and (ii) its predictive value for risk to relapse in a cohort of 50 severely affected chronic alcoholic patients and (iii) to monitor recovery of HC-related functions upon strict abstention from alcohol. Patients underwent a 2-year neuropsychological follow-up including HC-associated tests (Verbal Learning Test, VLT; Nonverbal Learning Test, NVLT; 'City Map Test' of Learning and Memory Test, LGT-3), as well as tests of intelligence and attention in the framework of OLITA (Outpatient Long-Term Intensive Therapy for Alcoholics), a programme with careful abstinence monitoring. At study entry, 30/50 (60%) alcoholics had HC dysfunction which tended to predict a lower long-term abstinence probability (P = 0.058). Of the subgroup that could be followed under conditions of strictly monitored alcohol abstinence (n = 32; age 44.7 +/- 6.2 years; 23 men, 9 women), 53% (17/32) exhibited distinct HC dysfunction at inclusion which returned to normal after 2 years. Patients with initially normal HC function (9/32) and patients with additional brain damage of different aetiologies (6/32) failed to show improvement on HC-related tests. While the former displayed stably normal HC test performance, the latter remained on a performance level below normal. Demonstrating slow but remarkable regeneration of HC functions upon strict abstention from alcohol, our data strongly support abstinence-oriented long-term treatment of alcoholics. The absence of functional recovery in patients with additional causes of brain damage might be explained by the 'dual hit' exhausting the regenerative potential of the HC."],["dc.identifier.doi","10.1093/alcalc/agl104"],["dc.identifier.gro","3150510"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/7282"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.relation.issn","0735-0414"],["dc.title","Recovery of hippocampus-related functions in chronic alcoholics during monitored long-term abstinence"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]

Although EPO has been considered to be a safe and well-tolerated drug over 2 decades, recent studies have identified increased thromboembolic complications and/or mortality risks on EPO administration to patients with cancer or chronic kidney disease. Accordingly, the double-blind, placebo-controlled, randomized German Multicenter EPO Stroke Trial (Phase II/III; ClinicalTrials.gov Identifier: NCT00604630) was designed to evaluate efficacy and safety of EPO in stroke.Methods— This clinical trial enrolled 522 patients with acute ischemic stroke in the middle cerebral artery territory (intent-to-treat population) with 460 patients treated as planned (per-protocol population). Within 6 hours of symptom onset, at 24 and 48 hours, EPO was infused intravenously (40 000 IU each). Systemic thrombolysis with recombinant tissue plasminogen activator was allowed and stratified for.Results— Unexpectedly, a very high number of patients received recombinant tissue plasminogen activator (63.4%). On analysis of total intent-to-treat and per-protocol populations, neither primary outcome Barthel Index on Day 90 (P=0.45) nor any of the other outcome parameters showed favorable effects of EPO. There was an overall death rate of 16.4% (n=42 of 256) in the EPO and 9.0% (n=24 of 266) in the placebo group (OR, 1.98; 95% CI, 1.16 to 3.38; P=0.01) without any particular mechanism of death unexpected after stroke.Conclusions— Based on analysis of total intent-to-treat and per-protocol populations only, this is a negative trial that also raises safety concerns, particularly in patients receiving systemic thrombolysis."],["dc.identifier.doi","10.1161/STROKEAHA.109.564872"],["dc.identifier.gro","3150483"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/7252"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.subject","clinical trial; hematopoietic growth factor; neuroprotection; NIHSS; rtPA"],["dc.title","Recombinant Human Erythropoietin in the Treatment of Acute Ischemic Stroke"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]

Here we used PC12 cells, an established model of neuronal differentiation, to investigate the effects of TPO on neuronal survival and differentiation. These cells expressed TPOR mRNA. TPO increased cell death in neuronally differentiated PC12 cells but had no effect in undifferentiated cells. Surprisingly, TPO inhibited nerve growth factor (NGF)-induced differentiation of PC12 cells in a dose- and time-dependent manner. This inhibition was dependent on the activity of Janus kinase-2 (JAK2). Using phospho-kinase arrays and Western blot we found downregulation of the NGF-stimulated phosphorylation of the extracellular signal-regulated kinase p42ERK by TPO with no effect on phosphorylation of Akt or stress kinases. NGF-induced phosphorylation of ERK-activating kinases, MEK1/2 and C-RAF was also reduced by TPO while NGF-induced RAS activation was not attenuated by TPO treatment. In contrast to its inhibitory effects on NGF signalling, TPO had no effect on epidermal growth factor (EGF)-stimulated ERK phosphorylation or proliferation of PC12 cells. Our data indicate that TPO via activation of its receptor-bound JAK2 delays the NGF-dependent acquisition of neuronal phenotype and decreases neuronal survival by suppressing NGF-induced ERK activity."],["dc.identifier.doi","10.1016/j.cellsig.2007.10.006"],["dc.identifier.gro","3150475"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/7244"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.subject","TPO; NGF; EGF; PC12; RAS; Mitogen-activated protein kinase; Cell death; Neurite outgrowth"],["dc.title","Thrombopoietin inhibits nerve growth factor-induced neuronal differentiation and ERK signalling"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]
