Women tend to have competence doubts for masculine-stereotyped domains (e.g., math), whereas men tend to think they can handle both feminine-stereotyped and masculine-stereotyped domains equally well. We suggest that perhaps women's more frequent experience with stereotype threat can partly explain why. Our results showed that when stereotype threat was primed in high school students (n = 244), th

Photodynamic therapy (PDT) using Photofrin IIR (PII) as a photosensitizer is currently being evaluated as a new treatment modality for superficial bladder cancer. An optimum therapeutic ratio requires uniform illumination of the whole bladder wall and accurate light dosimetry. The first clinical light dosimetry results (16 patients) are reported, obtained using a system which allows in situ measur

We give a sufficient condition for the Fourier dimension of a countable union of sets to equal the supremum of the Fourier dimensions of the sets in the union, and show by example that the Fourier dimension is not countably stable in general. A natural approach to finite stability of the Fourier dimension for sets would be to try to prove that the Fourier dimension for measures is finitely stable,

The aim of this study is to evaluate the existence of a possible relationship between global deuterium-labeled water (HDO) uptake rates and the diffusion geometry of human glioma xenografts in nude mice. HDO diffusion times in the whole extravascular tumor volume were estimated by combining quantitative (1)H-MR diffusion imaging and morphometric analysis of intercapillary distances in two tumor li

The aim of this study was to provide in vivo experimental evidence for the proposed biological significance of the creatine kinase (CK)/phosphocreatine (PCr) system in the energy metabolism of skeletal muscle. As a test system we compared hindlimb muscle of knockout mice lacking the cytosolic M-type (M-CK(-)/(-)), the mitochondrial ScMit-type (ScCKmit(-)/(-)), or both creatine kinase isoenzymes (C

Localized proton MR spectra of mouse skeletal muscle obtained at 7 T show dipole-dipole coupling effects for creatine and putative taurine resonances and for the lactate methine signal. These effects are independent of the presence of creatine kinase. The intensity of the methylene (1)H resonance of creatine is not different between wild-type and creatine kinase deficient mice, which have a lower

31P magnetic resonance spectroscopy (MRS) offers a unique non-invasive window on energy metabolism in skeletal muscle, with possibilities for longitudinal studies and of obtaining important bioenergetic data continuously and with sufficient time resolution during muscle exercise. The present paper provides an introductory overview of the current status of in vivo 31P MRS of skeletal muscle, focusi

A new model-free method is presented that automatically corrects for phase shifts, frequency shifts, and additional lineshape distortions of one single resonance peak across a series of in vivo NMR spectra. All separate phase and frequency variations are quickly and directly derived from the common lineshape in the data set using principal component analysis and linear regression. First, the new a

This introductory article addresses approaches currently in use to process in vivo spectra. First, a brief overview is given of the information content represented by the parameters of MR signals. Subsequently, common steps in the processing of MR spectra such as pre-processing, normalisation and quantification and the use of prior knowledge are described. Finally, some prospects for more advanced

Creatine kinases are important in maintaining cellular-energy homeostasis, and neuroprotective effects have been attributed to the administration of creatine and creatine-like compounds. Herein we examine whether ablation of the cytosolic brain-type creatine kinase (B-CK) in mice has detrimental effects on brain development, physiological integrity or task performance. Mice deficient in B-CK (B-CK

We assessed the relationship between phosphocreatine (PCr) and creatine (Cr) content and creatine kinase (CK) activity in skeletal muscle of mice. The PCr and total Cr (tCr) concentrations, as well as CK activity, in hindlimb muscles of mice, with or without the cytosolic and mitochondrial isoforms of muscle creatine kinase (wild-type or CK--/-- mice), were determined by in vivo magnetic resonance
