Ganglioside GD3 shedding by human malignant melanoma cells

1989

Gangliosides appear to be important target molecules for immunological effector mechanisms on neuro-ectodermal tumors. Therefore in vitro studies were performed to examine whether ganglioside GD3, which is highly expressed on the cell surface of cultured human melanoma cells, is being shed into the culture medium. Measurable quantities of gangliosides GM3 and in particular GD3 were shed by the melanoma cells we have tested as detected on thin-layer chromatograms (TLC) stained with orcinol. Ganglioside GD3 was also evidenced by immunostaining with anti-GD3 MAb and by ELISA. The concentration of GD3 in the supernatant of human melanoma cells depended on the ganglioside pattern of the cell lin…

Immunorecognition of different ganglioside epitopes on human normal and melanoma tissues.

1992

There is increasing evidence that cell-surface gangliosides play a role in tumor growth, progression and metastases. In order to determine the frequency of ganglioside GD3 in patients with metastatic malignant melanoma for further therapeutic trials, GD3 ganglioside expression was determined in 119 tissue samples. Of these melanomas, 93% (111/119) were R-24-positive, which indicates the value of this diagnostic marker for melanoma. To study the structural epitopes of gangliosides, 10 ganglioside antibodies with defined specificities and affinities were tested on over 100 fresh-frozen tissue specimens of human normal and melanoma tissues. All the antibodies tested recognize the ganglioside G…

The association between extremely low-frequency electromagnetic fields and childhood leukaemia in epidemiology: enough is enough?

2010

Background: Previous pooled analyses have reported an association between magnetic fields and childhood leukaemia. We present a pooled analysis based on primary data from studies on residential magnetic fields and childhood leukaemia published after 2000. Methods: Seven studies with a total of 10 865 cases and 12 853 controls were included. The main analysis focused on 24-h magnetic field measurements or calculated fields in residences. Results: In the combined results, risk increased with increase in exposure, but the estimates were imprecise. The odds ratios for exposure categories of 0.1–0.2 μT, 0.2–0.3 μT and ⩾0.3 μT, compared with <0.1 μT, were 1.07 (95% CI 0.81–1.41), 1.16 (0.69–1.93)…

GD3 ganglioside: A marker for the diagnosis and treatment of neuroectodermal tumors?

Incidence, Medical Resource Utilisation and Costs of Hyperuricemia and Tumour Lysis Syndrome in Patients with Acute Leukaemia and Non-Hodgkin's Lymph…

2003

Hyperuricemia (HU) and tumour lysis syndrome (TLS) are complications of acute leukaemia and non-Hodgkin lymphoma (NHL) leading to increased morbidity and mortality. The objective of this study was to define incidence and calculate health care cost associated with HU and TLS. 788 acute leukaemia and NHL patients from Belgium, The Netherlands, Spain and UK were screened retrospectively for HU and TLS. Resource use related to HU and TLS was recorded and costs were calculated applying local unit costs. Results showed that HU occurred in 18.9% of patients, and 27.8% of them fulfilled TLS criteria. The cost of HU without TLS was 672 euros (SE 181), the cost of TLS 7,342 euros (SE 1,412). TLS requ…

Continuous cardiac index trending (ProAQT) via a radial arterial line versus standard care in general surgical patients

2015

Introduction Several single-center studies and meta-analyses have shown that perioperative goal-directed therapy may significantly improve outcomes in general surgical patients. We hypothesized that using a treatment algorithm based on pulse pressure variation, cardiac index trending by radial artery pulse contour analysis, and mean arterial pressure in a study group, would result in reduced complications, reduced length of hospital stay and quicker return of bowel movement postoperatively in abdominal surgical patients, when compared to a control group. Methods 160 patients undergoing elective major abdominal surgery were randomized to the Study Group (79 patients) or to the Control Group …

Growth and differentiation factor 15 (GDF15) belongs to the transforming growth factor-β (TGF-β) superfamily of proteins. Glial-derived neurotrophic factor (GDNF) family receptor α-like (GFRAL) is an endogenous receptor for GDF15 detected selectively in the brain. GDF15 is not normally expressed in the tissue but is prominently induced by “injury”. Serum levels of GDF15 are also increased by aging and in response to cellular stress and mitochondrial dysfunction. It acts as an inflammatory marker and plays a role in the pathogenesis of cardiovascular diseases, metabolic disorders, and neurodegenerative processes. Identified as a new heart-derived endocrine hormone that regulates body growth,…

I candidati cattolici siciliani alle elezioni del primo Parlamento unitario

2012

With the use of newspapers, manuscripts, letters and speeches, the article analyses the admission of Sicilian Catholic deputies in the first national Parliament, like Emerico Amari, Vito d’Ondes Reggio and Gregorio Ugdulena. It underlines their political programs, beliefs and the idea of political representation as an action that was in the best interest of the represented people. In the background there was a steady claim to Legazia Apostolica that could have continued to exist only in a system of regional autonomy. According to the Sicilian deputies, the national deputy’s mandate had to be based on administrative freedom and there was a need for institutional solutions to ensure the prosp…

Invariant natural killer T cells act as an extravascular cytotoxic barrier for joint-invading Lyme Borrelia

2014

CXCR6-GFP(+) cells, which encompass 70% invariant natural killer T cells (iNKT cells), have been found primarily patrolling inside blood vessels in the liver. Although the iNKT cells fail to interact with live pathogens, they do respond to bacterial glycolipids presented by CD1d on liver macrophage that have caught the microbe. In contrast, in this study using dual laser multichannel spinning-disk intravital microscopy of joints, the CXCR6-GFP, which also made up 60-70% iNKT cells, were not found in the vasculature but rather closely apposed to and surrounding the outside of blood vessels, and to a lesser extent throughout the extravascular space. These iNKT cells also differed in behavior,…

Strategic quantitative easing: Stimulating investment to rebalance the economy

2013

The Bank of England’s programmes of Quantitative Easing (QE) and Funding for Lending (FLS) are failing to stimulate GDP and rebalance the economy. Both policies falsely assume that the UK’s risk-averse capital markets, corporate sector and constrained banking system can be nudged into supporting the productive economy. We propose a new approach: one that channels investment directly into new housing, infrastructure and SME lending, boosting productivity and exports. QE must become less scattergun and more strategic, with reformed governance structures to match.
