Repression of SHP-1 expression by p53 leads to trkA tyrosine phosphorylation and suppression of breast cancer cell proliferation.
The nerve growth factor (NGF) receptor, trkA, the tumour suppressor p53 and the phosphatase SHP-1 are critical in cell proliferation and differentiation. SHP-1 is a trkA phosphatase that dephosphorylates trkA at tyrosines ...

GALICS II : The [ α/Fe]-mass relation in elliptical galaxies
Aims. We test whether the mass-and σ-[α/Fe] relations in the stellar populations of early-type galaxies can be reproduced by a cosmologically motivated assembly history for spheroids.Methods. We implement a detailed treatment ...
In this progress report we review recent work which has investigated the process of glaciohydraulic supercooling and its significance for a range of glaciological and geological phenomena. Since our last report (Knight and ...
Measuring atmospheric composition change
Scientific findings from the last decades have clearly highlighted the need for a more comprehensive approach to atmospheric change processes. In fact, observation of atmospheric composition variables has been an important ...
High-accuracy U-233(n, f) cross-section measurement at the white-neutron source n_TOF from near-thermal to 1 MeV neutron energy
The U-233(n, f) cross section has been measured at the white neutron source n_TOF in a wide energy range with a dedicated fission ionization chamber. We report here the results from similar to 30 meV to 1 MeV neutron energy. ...
Large-scale analysis of Influenza A virus sequences reveals potential drug-target sites of non-structural proteins
The non-structural protein 1 (NS1) of the influenza A virus and the NS2 protein, which is also known as nuclear export protein, play important roles in the infectious life cycle of the virus. The objective of this study ...
Observer Variation in Interpreting 18F-FDG PET/CT Findings for Lymphoma Staging
Many studies demonstrate a high accuracy for PET in staging lymphoma, but few assess observer variation. This study quantified agreement for staging lymphoma with PET/CT. Methods: The PET/CT images of 100 patients with ...
Factors related to successful transcatheter closure of atrial septal defects using the Amplatzer septal occluder
The Amplatzer septal occluder (ASO) is used for transcatheter closure of atrial septal defects (ASDs). This study aimed to determine the factors influencing successful closure with the ASO. A retrospective analysis of 69 ...
