Corticosteroid-free immunosuppression in liver transplantation: a meta-analysis and meta-regression of outcomes.
2009
To examine the impact of steroid withdrawal from the immunosuppression protocols in liver transplantation. The electronic databases Medline, Embase, Pubmed and the Cochrane Library were searched. Meta-analysis pooled the effects of outcomes of a total of 2590 patients enrolled into 21 randomized controlled trials (RCTs), using classic and modern meta-analytic methods. Meta-analysis of RCTs addressing patients transplanted for any indication showed no differences between corticosteroid-free immunosuppression and steroid-based protocols in most of the analyzed outcomes. More importantly, steroid-free cohorts appeared to benefit in terms of de novo diabetes mellitus development [R.R = 1.86 (1.…
Preclinical report on allogeneic uterus transplantation in non-human primates
2013
Study question Is it possible to perform allogeneic uterus transplantation (UTx) with a donation from a live donor in a non-human primate species and what immunosuppression is needed to prevent rejection? Summary answer Allogeneic UTx in the baboon is a donor- and recipient-safe surgical procedure; immunosuppression with induction therapy and a triple protocol should be used. What is known already UTx may become a treatment for absolute uterine factor infertility. Autologous UTx models have been developed in non-human primates with reports on long-term survival of the uterine grafts. STUDY DESIGN, SIZEAND DURATION: This experimental study included 18 female baboons as uterus donors and 18 f…
Bilaterale Nierenrindennekrosen im Rahmen eines Sanarelli-Shwartzman-Ph�nomens nach Pneumokokkenmeningitis bei chronisch-essentieller Erythroblastope…
1966
Es wird uber den Verlauf einer chronisch-essentiellen Erythroblastopenie (sog. Blackfan-Diamond-Anamie) bei einem 4 Jahre, 11 Monate alten Madchen berichtet. Dabei erweckten die lange Verlaufsdauer, die Therapie sowie deren Komplikationen besonderes Interesse, wobei wir der interkurrenten Meningokokken-Meningitis sowie der todlichen Pneumokokkenmeningitis in Verbindung mit Anurie, hamorrhagischer Diathese und Kreislaufkollaps besondere Bedeutung beimasen. Pathologisch-anatomisch wurden Organveranderungen gefunden, die sich einem Sanarelli-Shwartzman-Phanomen zuordnen liesen. Dabei standen bilaterale Nierenrindennekrosen, die Verstopfung kleiner Nierenrindengefase sowie der Glomeruluscapilla…
Endotheliotropic (hemolytic) nephroangiopathy and its various manifestation forms (thrombotic microangiopathy, primary malignant nephrosclerosis, hem…
1980
In hemolytic-uremic syndrome (HUS) various lesion types in the kidneys are observed in childhood. These are designated as the “glomerular type=G type” (essentially identical with thrombotic microangiopathy), as “arterial type=A type” (essentially identical with primary malignant nephrosclerosis (PMN)) or as “mixed type=G/A type”. With reference to characteristic cases, the most important morphological findings are described. In adults, in whom other diagnostic terms are used besides HUS, the same nephropathological types are observed. In the two phases of life, there occurs in addition renal cortical necrosis in subtotal nephroangiothrombosis. The G type and A type also have a different cli…
Zinc-positive boutons in the cerebral cortex of lizards show glutamate immunoreactivity
1991
Zinc-positive boutons, originating in the medial cortex of lizards, exhibit glutamate immunoreactivity. This finding supports the presumed homology between lizard zinc-positive boutons and the hippocampal mossy fibres of mammals, which are also glutamate-immunoreactive and zinc-positive. Zinc-positive boutons of lizards contain a chelatable pool of zinc located in the hippocampal mossy fibres of mammals. These synaptic systems also contain glutamate, which indicates a possible simultaneous action of zinc and glutamate during synaptic transmission.
Timm-staining intensity is correlated with the density of Timm-positive presynaptic structures in the cerebral cortex of lizards
1987
In cortical areas of the lizard, Podarcis hispanica, Timm staining reveals a distinct pattern of lamination. At the electron-microscope level, virtually all of the reaction product is located in the synaptic vesicles of Timm-positive boutons. Using linear-regression analysis, the area density of Timm-positive bouton profiles as well as the numerical and volume density of stained vesicles were found to be closely correlated with the light-microscopic densitometric values obtained for each Timm-positive cortical zone. We discuss the possibility of estimating stereological electron-microscopic data parameters from densitometric measurements at the light-microscope level.
Effects of the Enriched Sports Activities-Program on Executive Functions in Italian Children.
2020
Physical activity (PA) during childhood plays an important role in brain development. This role is played in both the structural domain, prefrontal cortex area, and in the functional domain, involving the higher cognitive functions, including the executive functions (EF). Working memory (WM), inhibition, and switching as fundamental EF were investigated in an Italian children sample before and after four months of an Enriched Sports Activities-Program (ESA-Program). EFs were assessed at pre-test and post-test using, respectively, the digit span test, the color word Stroop test, and the trail making test derived from Millisecond Software. The Italian sample was composed of 141 children aged …
Hsp70 localizes differently from chaperone Hsc70 in mouse mesoangioblasts under physiological growth conditions
2008
Mouse A6 mesoangioblasts express Hsp70 even in the absence of cellular stress. Its expression and its intracellular localization were investigated under normal growth conditions and under hyperthermic stress. Immunofluorescence assays indicated that without any stress a fraction of Hsp70 co-localized with actin microfilaments, in the cell cortex and in the contractile ring of dividing cells, while the Hsc70 chaperone did not. Hsp70 immunoprecipitation assays confirmed that a portion of Hsp70 binds actin. Immunoblot assays showed that both proteins were present in the nucleus. After heat treatment Hsp70 and actin continued to co-localize in the leading edge of A6 cells but not on microfilame…
Behavioural and neurochemical effects after repeated administration of N-ethylpentylone (ephylone) in mice
2022
N-ethyl-pentylone (NEP), also known as "ephylone" and N-ethylnorpentylone, has been identified as one of the most recent novel psychostimulants to emerge into the illicit drug market and it has been associated with some intoxications and even fatalities. However, little is known about the consequences of its repeated consumption as well as the role of the monoaminergic system in such consequences. Thus, the aim of our study was to investigate the neurochemical profile and the behavioural effects after both acute and repeated NEP exposure. Male OF1 mice were acutely (1, 3, 10 mg/kg, i.p.) or repeatedly (1, 3, 10 mg/kg, i.p., 5 days, twice/day) exposed to NEP, and anxiety-like behaviour, aggr…
Increased cerebrospinal fluid albumin and immunoglobulin A fractions forecast cortical atrophy and longitudinal functional deterioration in relapsing…
2017
Background: Currently, no unequivocal predictors of disease evolution exist in patients with multiple sclerosis (MS). Cortical atrophy measurements are, however, closely associated with cumulative disability. Objective: Here, we aim to forecast longitudinal magnetic resonance imaging (MRI)-driven cortical atrophy and clinical disability from cerebrospinal fluid (CSF) markers. Methods: We analyzed CSF fractions of albumin and immunoglobulins (Ig) A, G, and M and their CSF to serum quotients. Results: Widespread atrophy was highly associated with increased baseline CSF concentrations and quotients of albumin and IgA. Patients with increased CSFIgA and CSFIgM showed higher functional disabilit…
