In this paper, we study the convergence of weak and strong solutions of oscillatory perturbations of the Navier-Stokes equations and in particular the asymptotic behaviour of rotating uids and of slightly compressible uids.
The development of cytotoxic oedema during a stroke consists in cell swelling and shrinking of the extracellular space. This phenomenon is triggered by ion movements through voltage-gated channels, exchangers and pumps. During ischaemia, sodium, calcium and chloride enter the neurons whereas potassium and glutamate are expelled out of the cells. A… (More)
Optimising the delivery of antiangiogenic drugs requires the development of drug-disease models of vascular tumour growth that incorporate histological data indicative of cytostatic action. In this study, we formulated a model to analyse the dynamics of tumour progression in nude mice xenografted with HT29 or HCT116 colorectal cancer cells. In 30 mice,… (More)
Tumor angiogenesis is the process by which new blood vessels are formed and enhance the oxygenation and growth of tumors. As angiogenesis is recognized as being a critical event in cancer development, considerable efforts have been made to identify inhibitors of this process. Cytostatic treatments that target the molecular events of the angiogenesis process… (More)
For the purpose of developing somatic embryogenesis in Prunus avium L., immature zygotic embryos, collected from five donor trees and sorted into two size classes (C1: 2.5–3.5 and C2: 3.6–4.5 mm), received various experimental treatments. When cultured for 10 days on an inductive medium containing 18.1 μM 2,4-dichlorophenoxyacetic acid (2,4-d) and 9.3 μM… (More)
In this paper, we derive rigorously a classical simpliied model of ocean circulation , namely the so called homogeneous model of wind driven ocean circulation (see the monograph of J. Pedlosky 19]) and two of its possible boundary layer behavior, namely Munk layers and Stommel layers.
The astrocytic response to stroke is extremely complex and incompletely understood. On the one hand, astrocytes are known to be neuroprotective when extracellular glutamate or potassium is slightly increased. But, on the other hand, they are considered to contribute to the extracellular glutamate increase during severe ischaemia. A mathematical model is… (More)
With the aim of inhibiting cancer growth and reducing the risk of metastasis, pharmaceutical companies in the early 1990s developed anti-metastatic agents called inhibitors of metalloproteinases (MMPi). Despite the promising results obtained in pre-clinical studies, results of Phase III trials have been somewhat disappointing for late stage cancer patients.… (More)
Indirect somatic embryogenesis was obtained inPrunus avium L. from either somatic or zygotic embryos. An embryogenic line was established by reinduction of embryogenic calluses from somatic embryos. The line was maintained for more than 3 years through 6 generations of embryogenic cultures. In the last 2 generations, more than 50% of the explants were… (More)
