The eukaryotic elongation factor-1 (EF-1) consists of four subunits, EF-1 alpha, EF-1 beta, EF-1 gamma and EF-1 delta which induce efficient transfer of aminoacyl-tRNA to the ribosome. In this process EF-1 alpha.GTP acts as the carrier of the aminoacyl-tRNA on its way to the ribosome. After release of aminoacyl-tRNA to the ribosome under concomitant(More)
In addition to the lysosomal glucocerebrosidase, a distinct beta-glucosidase that is also active towards glucosylceramide could be demonstrated in various human tissues and cell types. Subcellular fractionation analysis revealed that the hitherto undescribed glucocerebrosidase is not located in lysosomes but in compartments with a considerably lower(More)
In quiescent embryos of the brine shrimp Artemia, the level of aminoacylation of transfer RNAs is low. During resumption of development the charging level of transfer RNAs increases, concomitant with the activation of protein synthesis. The total level of charging rises dramatically from an average of 4% to 50% within a period of 24 h of development. The(More)
Cold intolerance is a serious long-term problem after injury to the ulnar and median nerves, and its pathophysiology is unclear. We investigated the use of infrared thermography for the analysis of thermoregulation after injury to peripheral nerves. Four patients with injuries to the ulnar nerve and four with injuries to the median nerve (4-12 years after(More)
Glucagon-like peptide-1 (GLP-1) is a small peptide hormone with potent insulinotropic activity and represents a promising new therapeutic tool for the treatment of diabetes. Like many other therapeutic peptides, GLP-1 is commonly produced using chemical synthesis methods, but is limited by product quantity and cost. The advent of recombinant DNA technology(More)
Two components of the protein biosynthetic machinery, valyl-transfer RNA synthetase (VRS) and elongation factor 1 (EF-1), have been isolated as a complex from several mammalian tissues. However, yeast VRS, which lacks an amino-terminal extension, does not associated with EF-1. We purified VRS from the brine shrimp Artemia and investigated its interaction(More)
Patients who acquired an upper extremity nerve injury often complain about cold intolerance, reduced sensitivity and decreased task performance. This study tried to quantify these complaints and look in more detail at the thermal reaction to local cold exposure of the affected limb. We found that 36% of 107 subjects could be classified as cold intolerant.(More)
The case is presented of a patient who delivered an immature infant after an intrauterine candidial infection in the presence of an intrauterine contraceptive device (IUD). 8 other cases of intrauterine Candida infection leading to immature deliveries were gathered from the literature. On the basis of the pathologic findings, the medium of infection is(More)
