Chelation treatment in sickle-cell-anaemia: much ado about nothing?
2011
Summary Blood transfusions may prevent and treat serious complications related to sickle-cell disease (SCD) when performed according to specific guidelines. However, blood transfusion requirements in SCD inevitably lead to increased body iron burden. An adequate chelation treatment may prevent complications and reduce morbidity and mortality. This review evaluates the effectiveness, safety and costs of chelation treatment. The included trials were examined according to the recommendations of the American College of Cardiology (ACC) and the American Heart Association (AHA). Overall, 14 trials and a total of 502 patients with SCD were included in this review. Deferoxamine alone (s.c. or i.v.)…
Iron Chelation Therapy in thalassaemia major: a sistematic review with meta-analyses of 1520 patients included on randomized clinical trials
2011
The effectiveness of deferoxamine (DFO), deferiprone (DFP), or deferasirox (DFX) in thalassemia major was assessed. Outcomes were reported as means±SD, mean differences with 95% CI, or standardized mean differences. Statistical heterogeneity was tested using χ2 (Q) and I2. Sources of bias and Grading of Recommendations Assessment, Development and Evaluation system (GRADE) were considered. Overall, 1520 patients were included. Only 7.4% of trials were free of bias. Overall measurements suggest low trial quality (GRADE). The meta-analysis suggests lower final liver iron concentrations during associated versus monotherapy treatment (p<0.0001), increases in serum ferritin levels during DFX 5, 1…
On the hemagglutinating and hemolytic activity of measles virus variants.
1967
The hemagglutinating (HA) and hemolytic (HL) activity of two measles virus variants, differing with regard to type of CPE and other characteristics, have been investigated.
EXPERIENCE OF REMOVING BENIGN NEOPLASMS OF SKIN IN CERVICOFACIAL AREA USING THE METHOD OF PLASMA ABLATION
2017
Choosing appropriate methods for removal of benign skin lesions (BSL) in the cervicofacial area has always been an important and challenging issue. Removal of the BSL is indicated and performed for medical and aesthetic reasons. A method with less painful procedures, a short healing period, without noticeable long-lasting traces (such as scars, dyschromia) and, predictably, fewer repeat procedures is preferred. Objectives. Evaluation of the effectiveness, safety and convenience of BSL plasma ablation using Plexr® (GMV, Italy); Comparison of the reparative processes speed after the BSL removal in the cervicofacial area applying the Plexr® device with other instrumental methods (based on lite…

Translation of HTT mRNA with expanded CAG repeats is regulated by the MID1-PP2A protein complex.
2012
Expansion of CAG repeats is a common feature of various neurodegenerative disorders, including Huntington's disease. Here we show that expanded CAG repeats bind to a translation regulatory protein complex containing MID1, protein phosphatase 2A and 40S ribosomal S6 kinase. Binding of the MID1-protein phosphatase 2A protein complex increases with CAG repeat size and stimulates translation of the CAG repeat expansion containing messenger RNA in a MID1-, protein phosphatase 2A- and mammalian target of rapamycin-dependent manner. Our data indicate that pathological CAG repeat expansions upregulate protein translation leading to an overproduction of aberrant protein and suggest that the MID1-com…
The E3 Ubiquitin Ligase MID1 Catalyzes Ubiquitination and Cleavage of Fu
2014
Sonic Hedgehog (SHH)-GLI signalling plays an important role during embryogenesis and in tumorigenesis. The survival and growth of several types of cancer depend on autonomously activated SHH-GLI signalling. A protein complex containing the ubiquitin-ligase MID1 and protein phosphatase 2A (PP2A) regulates the nuclear localization and transcriptional activity of GLI3, a transcriptional effector molecule of SHH, in cancer cell lines with autonomously activated SHH signalling. However, the exact molecular mechanisms that mediate the interaction between MID1 and GLI3 remained unknown. Here, we show that MID1 catalyses the ubiquitination and proteasomal cleavage of the GLI3-regulator Fu. Our data…
Changes of several metabolic parameters of soya inoculated with phytopathogens at application nanochelates
2022
n greenhouse experiments changes in several metabolic parameters soybeans plants after inoculation by P. savastanoi pv. glycinea 9190, X. axonopodis pv. glycines 9192, BCMV, A. laidlawii on background pre-treatment by nanochelates (NHs) of V, Ge, Cu, Mo have been shown. The phenolic compounds content increased in leaves at inoculation by phytopathogens on background pre-treatment by NHs and without it. The content of H2O2 in leaves increased in variants: BCMV (+VNHs, GeNHs, CuNHs), 9192 (+VNHs, CuNHs), 9190 (+GeNHs, CuNHs), A. laidlawii+MoNHs. But it decreased in the variants: BCMV + MoNHs, A. laidlawii + VNHs, 9190 + VNHs, 9192 (+ GeNHs, CuNHs) compared to controls. The peroxidase activity…
Mechanisms of cell death in canine parvovirus-infected cells provide intuitive insights to developing nanotools for medicine
2010
Jonna Nykky, Jenni E Tuusa, Sanna Kirjavainen, Matti Vuento, Leona GilbertNanoscience Center and Department of Biological and Environmental Science, University of Jyv&auml;skyl&auml;, FinlandAbstract: Viruses have great potential as nanotools in medicine for gene transfer, targeted gene delivery, and oncolytic cancer virotherapy. Here we have studied cell death mechanisms of canine parvovirus (CPV) to increase the knowledge on the CPV life cycle in order to facilitate the development of better parvovirus vectors. Morphological studies of CPV-infected Norden laboratory feline kidney (NLFK) cells and canine fibroma cells (A72) displayed characteristic apoptotic events. Apoptosis was f…
