Interferon α interferes with immunological tolerance.

2013

The ability of regulatory T cells (Tregs) to promote immunological tolerance represents an important obstacle in cancer immunotherapy. We have recently discovered that the clinically established immunotherapeutic agent interferon α (IFNα) inactivates the suppressive functions of human Tregs. Here, we outline the mechanisms whereby IFNα mediates this important function and discuss its therapeutic implications for cancer immunotherapy.

Dealing with the right of way in advanced traffic simulation. A characterization of drivers' behaviours in a multi-agent approach

2017

International audience; With the emergence of ADAS and autonomous vehicle, the need of simulation software to test advanced systems and models is unavoidable. The objective of this work is to characterize, in a multi-agent approach, the traffic vehicles behaviours, and to model them in a versatile traffic simulator, serving as a testing tool for integration in the traffic module of the SCANeR Studio T M simulation software. The algorithm will bring more natural interactions between vehicles in simulation and allow the emergence of new relevant situations for autonomous vehicles, observable in real, such as collision risk situations or even accidents, which have for now to be scripted in sce…

CONSORT compliance in randomized surgical trials assessing the analgesic and anti-inflammatory effectiveness of preoperative drug management of patie…

2022

Investigate methodological quality of clinical trials in mandibular third molar surgery and its compliance with the consort statement. An electronic search was performed in five journal websites, chose the five scientific journals with the greatest impact factor in oral and maxillofacial surgery according to the SCImago Journal Rank. The compliance of studies with the CONSORT statement was assessed. Also, the risk of bias of each study was evaluated. Twenty-nine studies were included. The average CONSORT compliance score was 25.50 (79.68%). Most studies were performed in the Americas (n = 14, 48.3%) and Asia (n = 10, 34.5%). Parallel-group (n=15, 51.7%) and split-mouth RCTs (n=11, 38%) were…

Double copies of blaKPC-3::Tn4401a on an IncX3 plasmid in Klebsiella pneumoniae successful clone ST512 from Italy

2015

ABSTRACT A carbapenem-resistant sequence type 512 (ST512) Klebsiella pneumoniae carbapenemase 3 (KPC-3)-producing K. pneumoniae strain showing a novel variant plasmid content was isolated in Palermo, Italy, in 2014. ST512 is a worldwide successful clone associated with the spread of bla KPC genes located on the IncFIIk pKpQIL plasmid. In our ST512 strain, the bla KPC-3 gene was unusually located on an IncX3 plasmid, whose complete sequence was determined. Two copies of bla KPC-3 ::Tn 4401a caused by intramolecular transposition events were detected in the plasmid.

Dipeptidyl Enoates As Potent Rhodesain Inhibitors That Display a Dual Mode of Action

2015

Dipeptidyl enoates were prepared through a high-yielding two-step synthetic route. They have a dipeptidic structure with a 4-oxoenoate moiety as a warhead with multiple reactive sites. Dipeptidyl enoates were screened against rhodesain and human cathepsins B and L, and were found to be potent and selective inhibitors of rhodesain. Among them (S,E)-ethyl 5-((S)-2-{[(benzyloxy)carbonyl]amino}-3-phenylpropanamido)-7-methyl-4-oxooct-2-enoate (6) was the most potent, with an IC50 value of 16.4 nm and kinact/Ki=1.6×106 m−1 s−1 against rhodesain. These dipeptidyl enoates display a reversible mode of inhibition at very low concentrations and an irreversible mode at higher concentrations. Inhibition…

Pelaaja-agentit jalkapalloilun globalisoitumisen ilmentäjinä Suomessa

2012

Suomalainen jalkapalloilu on globalisoitunut vauhdilla ensimmäisten ulkomaalaisten pelaajien tultua pääsarjaan 1970–luvun lopulla. 80–luku oli vielä varovaista kokeilujen aikaa, mutta 90–luvulla pelaajasiirrot yleistyivät rajojen auettua ja jalkapallomaailmaan tulleen Bosman-säännön myötä. 2000-luvulla Veikkausliigaseuroilla on ollut keskimäärin noin viisi ulkomaalaista pelaajaa seurakohtaisten toimintatapojen ollessa hyvin erilaisia. 2000–luvulla kiinnostus on siirtynyt afrikkalaisiin pelaajiin, joiden määrä Veikkausliigassa on noussut merkittävästi. Vuonna 2010 Veikkausliigan ulkomaalaisista peräti 37 % oli afrikkalaisia pelaajia. 90-luvulla Bosmanpäätöksen myötä lisääntynyt pelaajatarjon…

Neuronal effects of Sugammadex in combination with Rocuronium or Vecuronium.

2017

Rocuronium (ROC) and Vecuronium (VEC) are the most currently used steroidal non-depolarizing neuromuscular blocking (MNB) agents. Sugammadex (SUG) rapidly reverses steroidal NMB agents after anaesthesia. The present study was conducted in order to evaluate neuronal effects of SUG alone and in combination with both ROC and VEC. Using MTT, CASP-3 activity and Western-blot we determined the toxicity of SUG, ROC or VEC in neurons in primary culture. SUG induces apoptosis/necrosis in neurons in primary culture and increases cytochrome C (CytC), apoptosis-inducing factor (AIF), Smac/Diablo and Caspase 3 (CASP-3) protein expression. Our results also demonstrated that both ROC and VEC prevent these…

Antibacterial activity and cytotoxicity of selected Egyptian medicinal plants.

2011

Medicinal plants have been used as a source of remedies since ancient times in Egypt. The present study was designed to investigate the antibacterial activity and the cytotoxicity of the organic extracts from 16 selected medicinal plants of Egypt. The study was also extended to the isolation of the antiproliferative compound jaeschkeanadiol p-hydroxybenzoate (FH-25) from Ferula hermonis. The microbroth dilution was used to determine the minimal inhibitory concentration (MIC) of the samples against twelve bacterial strains belonging to four species, Providencia stuartii, Pseudomonas aeruginosa, Klebsiella pneumoniae, and Escherichia coli, while a resazurin assay was used to assess the cytoto…
