OBJECTIVE To elucidate the value of early computed tomographic (CT) signs of stroke in predicting the occlusion site in the cerebral arteries. PATIENTS 105 consecutive patients with acute embolic stroke affecting the anterior circulation. METHODS Four early signs were evaluated on cranial CT within six hours of stroke onset: loss of the insular ribbon (LIR); attenuation of the lentiform nuc...

We consider vector-valued solutions to a linear transmission problem, and we prove that Lipschitz-regularity on one phase is transmitted the next phase. More exactly, given solution u:B1⊂Rn→Rm elliptic system div((A+(B−A)χD)∇u)=0inB1,where A B are Dini continuous, uniformly matrices, if ∇u∈L∞(D) then u Lipschitz in B1/2. similar result also derived for parabolic counterpart of this problem.

We study a system of nonlinear partial differential equations resulting from the traditional modelling of oil engineering within the framework of the mechanics of a continuous medium. Existence and regularity of the optimal solutions for this system is established. Mathematics Subject Classification 2000: 49J20, 35K55.

INTRODUCTION We aimed to understand the changes in cartilage lubricin expression and immunolocalisation in responsed to treadmill running with different intensities in a rat model. METHODS A total of 24 male Wistar rats were randomly assigned into groups of control (CON), low-intensity running (LIR), moderate-intensity running (MIR), and high-intensity running (HIR). Rats in LIR, MIR, and HIR...

A modern biomedical research project can easily contain hundreds of analysis steps and lack of reproducibility of the analyses has been recognized as a severe issue. While thorough documentation enables reproducibility, the number of analysis programs used can be so large that in reality reproducibility cannot be easily achieved. Literate programming is an approach to present computer programs ...

The nonclassical class I MHC molecule HLA-G is selectively expressed on extravillous cytotrophoblast cells at the maternal-fetal interface during pregnancy. HLA-G can inhibit the killing mediated by NK cells via interaction with the inhibitory NK cell receptor, leukocyte Ig-like receptor-1 (LIR-1). Comparison of the sequence of the HLA-G molecule to other class I MHC proteins revealed two uniqu...

Immunoglobulin (Ig) function varies by isotype and antibody activity is best mediated by isotypes most able to control the inciting infection. In pigs, a high ratio of IgG1:IgG2 is associated with resistance to disease caused by the extra-cellular bacterium Actinobacillus pleuropneumoniae. This ratio is controlled by type 1/type 2 cytokines in vitro, reflecting cell- (CMI) or antibody-mediated ...
