Assessment of tumour vascularity may characterize malignancy as well as predict responsiveness to anti-angiogenic therapy. Non-invasive measurement of tumour perfusion and blood vessel permeability assessed as the transfer constant, K(trans), can be provided by dynamic contrast-enhanced magnetic

Basic fibroblast growth factor (FGF) and alpha-thrombin can stimulate DNA synthesis in Chinese hamster fibroblasts (CCL39) by two separate signaling pathways (Chambard, J.C., Paris, S., L'Allemain, G., and Pouysségur, J. (1987) Nature 326, 800-803) but can also act synergistically. We have examined

We studied the possible involvement of ten candidate genes in autism: proenkephalin, prodynorphin, and proprotein convertase subtilisin/kexin type 2 (opioid metabolism); tyrosine hydroxylase, dopamine receptors D2 and D5, monoamine oxidases A and B (monoaminergic system); brain-derived neurotrophic

The hyposensibilisation therapy was realized in a population of 72 adult asthma patients allergic to house dust, feathers and molds. In this number 52 patients were treated by aqueous extracts of allergens produced by Pasteur Institute in Paris (20 patients by house dust extract only) and 20

Parkinson's disease (PD) is an insidious onset neurodegenerative disease affecting approximately 1% of the population over the age of 65. So far available therapies for PD have only aimed at improving or alleviating symptoms, but not at slowing, preventing, and reversing the course of PD. Recently,

c-Abl is activated in the brain of Parkinson's disease (PD) patients and in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-intoxicated mice where it inhibits parkin through tyrosine phosphorylation leading to the accumulation of parkin substrates, and neuronal cell death. In the present study,

Lesch-Nyhan (LN) disease is a severe X-linked recessive neurological disorder associated with a loss of hypoxanthine guanine phosphoribosyltransferase activity (HPRT, EC 2.4.2.8). We have studied the second example of a female patient with LN disease. The molecular basis of HPRT deficiency in this

While the anti-apoptotic effect of paricalcitol has been demonstrated in various animal models, it is not yet clear whether paricalcitol attenuates the apoptosis in gentamicin (GM)-induced kidney injury. We investigated the effect of paricalcitol on apoptotic pathways in rat kidneys damaged by GM.

Acquired resistance to epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) is the most important limiting factor for treatment efficiency in EGFR-mutant non-small cell lung cancer (NSCLC). Much work has linked the epithelial-mesenchymal transition (EMT) to the emergence of drug

EGFR tyrosine kinase inhibitors (TKIs) are widely used for advanced nonsmall cell lung cancer (NSCLC) patients with a sensitizing EGFR mutation and provide a promising treatment strategy. However, acquired resistance to EGFR-TKIs restricts their application. The mechanisms underlying acquired

Intrinsic tyrosines, as monitored by fluorescence spectroscopy, are sensitive reporters of local, Ca(2+)-induced conformational changes in troponin C (TnC). Rabbit skeletal TnC contains two tyrosines (Y10 in the N-helix, and Y109 in site 3 in the C-terminal domain) in distinct microenvironments:

This retrospective study evaluated the efficiency and tolerance of rituximab in the management of resistant myasthenia gravis (MG). All patients who received rituximab for the treatment of MG between 2004 and 2015 at Pitié-Salpétrière University Hospital (Paris, France) were included. The efficacy

Non-small-cell lung cancer (NSCLC) is the most common non-acquired immune deficiency syndrome-related malignancy responsible for death. Mutational status is crucial for choosing treatment of advanced NSCLC, yet no data is available on the frequency of epidermal growth factor receptor (EGFR) and
