A method for increasing the productivity of ESI LC-MS/MS (electrospray ionization-liquid chromatography-tandem mass spectrometry) was proposed and applied. After IF (isoelectric focusing) of the sample using IPG (immobilized pH gradient) strip, the strip was cut to sections, and every section was treated according to trypsinolysis protocol for MS/MS analysis. The peptides produced were further analyzed by ESI LC-MS/MS. The procedure allows to: •identify many more proteins and proteoforms compared to shotgun analysis of extracts...

An asymmetric total synthesis of (+)-6-hydroxythiobinupharidine (1b) and (-)-6-Hydroxythionuphlutine (2b), a set of hemi-aminal containing dimeric sesquiterpenes isolated from yellow water lilies of the Nuphar genus, is described. The central bis-spirocyclic thiolane was forged through the Stevens rearrangement of a sulfonium ylide, generated in-situ from the coupling of a copper carbenoid with a spirocyclic thietane. This strategy diverges both from the proposed biosynthesis1 and previous syntheses of this family of alkaloids,2,3 all of which employ dimerization of symmetric monomers to form the aforementioned central thiolane...

INTRODUCTION: Adequate blood oxygenation and ventilation/perfusion matching should be main goal of anaesthetic and intensive care management. At present, one of the methods of improving gas exchange restricted by ventilation/perfusion mismatching is independent ventilation with two ventilators. Recently, however, a unique device has been developed, enabling ventilation of independent lungs in 1:1, 2:1, 3:1, and 5:1 proportions. The main goal of the study was to evaluate the device's utility, precision and impact on pulmonary mechanics...

Whole-organ engineering is an innovative field of regenerative medicine with growing translational perspectives. Recent reports suggest the feasibility of decellularization and repopulation of entire human size hearts. However, little is known about the susceptibility of epicardial adipose tissue (EAT) to decellularization. Here, human size hearts of ovine donors were subjected to perfusion-based decellularization using detergent solutions. Upon basic histological evaluation and total DNA measurement myocardial regions prove largely decellularized while EAT demonstrated cellular remnants, further confirmed by transmission electron microscopy...

Host defence peptides (HDPs) derived from the C-terminus of thrombin are proteolytically generated by enzymes released during inflammation and wounding. In this work, we studied the effects of the prototypic peptide GKY25 (GKYGFYTHVFRLKKWIQKVIDQFGE), on neutrophil functions. In vitro, GKY25 was shown to decrease LPS-induced neutrophil activation. In addition, the peptide induced CD62L shedding on neutrophils without inducing their activation. Correspondingly, GKY25-treated neutrophils showed reduced attachment and rolling behaviour on surfaces coated with the CD62L ligand E-selectin...

Greater knowledge is needed of potential predictive factors for suicide in cases of alcohol addiction. Therefore, the aim of the study was to identify the socio-demographic variables and clinical factors associated with alcohol dependence which may have an influence on the occurrence of suicidal thoughts in alcohol-dependent patients. A group of 510 patients (396 male and 114 female) diagnosed with alcohol dependence syndrome were interviewed during the third week of therapy according to the Beck Depression Inventory (BDI), the Penn Alcohol Craving Scale (PACS) and the Short Alcohol Dependence Data Questionnaire (SADD)...

Background: Aescin, a natural mixture of saponins occurring in Aesculus hippocastanum, exhibits important flebotonic properties, being used in the treatment of chronic venous insufficiency in legs. The inclusion of aescin into cyclodextrins (CDs) is a technical solution for its incorporation into the textile of stockings, but details of the physicochemistry of these host-guest systems are lacking. This work investigates the inclusion of aescin into the cavities of two native cyclodextrins, β-CD and γ-CD. Results: The continuous variation method applied to aqueous-phase (1)H nuclear magnetic resonance ((1)H NMR) has demonstrated that the preferred CD/aescin inclusion stoichiometries are 2:1 with β-CD and 1:1 with γ-CD...

Toll-like receptors (TLR) triggering of B cells are known to promote B cell expansion, differentiation of B cells into antibody-producing and memory cells, but the TLR responses of porcine B cells is poorly characterized. Therefore, this study investigated the response pattern of porcine B cell subsets to a large collection of TLR ligands and demonstrates that the TLR2 ligand Pam3Cys-SK4 and the TLR7/8 ligands gardiquimod and resiquimod are particularly efficient at inducing proliferation, CD25 and CCR7. This activation was also determined in B-cell subpopulations including a CD21(+)IgM(+) subset, an IgG(+) subset and two putative B1-like subsets, defined as CD21(-)IgM(high)CD11R1(+)CD11c(+)CD14(+) and CD21(-)IgM(high) CD11R1(-)CD11c(+)CD14(-) B cells...

The most recent European guidelines and task force reports on hospital-acquired pneumonia (HAP) and ventilator-associated pneumonia (VAP) were published almost 10 years ago. Since then, further randomised clinical trials of HAP and VAP have been conducted and new information has become available. Studies of epidemiology, diagnosis, empiric treatment, response to treatment, new antibiotics or new forms of antibiotic administration and disease prevention have changed old paradigms. In addition, important differences between approaches in Europe and the USA have become apparent...
