Cancer-associated fibroblasts (CAF) attract increasing attention as potential cancer drug targets due to their ability to stimulate, for example, tumor growth, invasion, angiogenesis, and metastasis. However, the molecular mechanisms causing the tumor-promoting properties of CAFs remain poorly understood. Forkhead box F1 (FoxF1) is a mesenchymal target of hedgehog signaling, known to regulate mese

This paper describes a driving simulator trial to evaluate driver reactions to a number of alternative information/ warning modes of a multi-modal system for the “safe speed and safe distance” concept. In 2006, eight Human Machine Interaction alternatives, consisting of a combination of visual, haptic and auditory modes were used alternatively to give information/warning to the driver on safe spee

BACKGROUND: Solutions of iodine contrast media (CM) used for selective coronary arteriography (CA) should have minimal propensity to cause ventricular fibrillation (VF). Commonly used CM for CA are nonionic monomers or dimers. PURPOSE: To compare VF propensity of ready-to-use solutions of one nonionic dimer, iodixanol, and five nonionic monomers, iobitridol, iopamidol, iomeprol, iopromide, and iov

The dynamical theory of X-ray spectra due to Nozieres and De Dominicis (ND, 1969) is evaluated here numerically for numerous model systems including cases where the core-hole potential possesses a bound state. It is shown that the resulting emission spectra obey the final-state rule rather accurately. An approximate but analytical derivation of this rule is given which provides insight into the me

The dysfunction of misplaced or dislodged endovascular endoprostheses, may be a serious complication, and endovascular removal may be attempted in some cases.

Optical absorption spectroscopy is a widely used analytical tool for constituent analysis in many applications. According to the Beer-Lambert law, the transmitted light intensity through a homogeneous medium is an exponential function of the product of the concentration, the total pathlength, and the absorption cross-section of the absorbing substance. By studying the intensity loss at the unique

Popular Abstract in Swedish Denna avhandlings inriktar sig i huvudsak mot utveckling och tillämpning av två nyligen framtagna optiska tekniker för förbränningsstudier. Dessa tekniker kallas mid-infrared polarisationsspektroskopi (IRPS) samt degenererad fyrvågsmixning (IR-DFWM), vilka båda är baserade på infrarött ljus med en våglängd runt 3 mikrometer, samt att teknikernas signalrespons är ickelinThe work reported in this thesis involved the development and application of two novel infrared non-linear laser techniques, namely mid-infrared polarization spectroscopy (IRPS) and mid-infrared degenerate four-wave mixing (IR-DFWM) to combustion diagnostics. These two techniques meet the needs of species concentration detection in combustion environments, especially for those species lacking acce

In a longitudinal study of 297 palliative care patients, 280 patients were followed from inclusion to death. Characteristics and health-related quality of life (HRQL) of the participants and those who later dropped out were compared at inclusion, and 3 and 2 months before their death. At inclusion, the dropouts were older (P = 0.001), had reduced Karnofsky performance score (P < 0.001), received m

Given an electronic wave function, generated by the MCHF program (LS format) or the MCHF_CI program (LSJ format), this program computes the hyperfine interaction constants, A(J) and B(J). In strong experimental magnetic fields, the splitting is also affected by the off-diagonal hyperfine constants A(J,J-1), B(J,J-1), and B(J,J-2) and these are computed as well, depending on the input data.
