Magnetic resonance-based assessment of quadriceps muscle fat has been proposed as surrogate marker in sarcopenia, osteoarthritis, and neuromuscular disorders. We presently investigated the association of quadriceps muscle fat with isometric strength measurements in healthy males using chemical shift encoding-based water-fat magnetic resonance imaging. Intermuscular adipose tissue fraction and i...
introduction: biofilm forming staphylococcus epidermidis is a main causative agent of infections related to medical devices. purification and evaluation of gly-ta polysaccharide from a biofilm-forming s. epidermidis as a putative vaccine candidate were the main goals of the current study. methods: taking advantage of size exclusion chromatography procedure, glycerol teichoic acid (gly-ta) was p...
INTRODUCTION High resolution magnetic resonance imaging of the temporal lobe shows most cases of mesial temporal lobe sclerosis, the most common cause of temporal lobe epilepsy (TLE). In combination with EEG it yields lateralizing results in approx. 90 % of the patients. Several clinical studies on adult patients as well as on children (1,2,3) have demonstrated that proton magnetic resonance sp...
Circulatory, respiratory, and digestive motions in Manduca sexta pupae were observed using proton-density weighted and fast-imaging with steady-state free procession magnetic resonance microscopy. Proton-density weighted images clearly differentiated pupal air sacs from the hemolymph and organs because, as expected, the air sacs appeared dark in these images. Steady-state free procession imagin...

We discuss procedures for error-tolerant spin control in environments that permit transient, large-angle reorientation of a magnetic bias field. Short sequences nonresonant magnetic-field pulses laboratory-frame meridional plane are derived. These shown to have band-pass excitation properties comparable established amplitude-modulated, resonant used static, high-field resonance. Using these pul...
