INTRODUCTION The aim of this study was to analyse whether patients with occupational asthma (OA) caused by low molecular weight (LMW) agents differed from patients with OA caused by high molecular weight (HMW) with regard to risk factors, asthma presentation and severity, and response to various diagnostic tests. METHODS Seventy-eight patients with OA diagnosed by positive specific inhalation...

Urinary protein obtained from a patient with a highly malignant brain tumor (astrocytoma, grade IV) was adsorbed to trimethylsilyl controlled-pore glass beads and selectively eluted with acetonitrile to yield a high molecular weight (HMW) human transforming growth factor (hTGF). This HMW hTGF promoted clonogenic cell growth in soft agar and competed for membrane receptors with mouse epidermal g...

high molecular weight (hmw) subunits of wheat glutenin are generally considered as playing a key role in gluten formation and structure, as well as to be closely related to wheat quality. the endosperm storage proteins of 80 synthetic lines and wheat cultivars (triticum aestivum) were fractionated through sodium dodecyl sulfate polyacrylamide gel electrophoresis to determine their high-molecula...

B-Raf mutations are identified in 40-50% of patients with melanoma and among them, the substitution of valine for glutamic acid at position 600 ((V600E)B-Raf) is the most frequent. Treatment of these patients with B-Raf inhibitors has been associated with a clear clinical benefit. Unfortunately, multiple resistance mechanisms have been identified and new potent and selective inhibitors are curr...
