- Objective: This study analyzed factors associated with injuries to hospitalized victims of nonfatal immersion-related events in Alaska from 1991 through 2000. Data: Alaska Trauma Registry (ATR) records of victims of nonfatal immersion events requiring hospitalization were examined to identify factors associated with injury outcomes. Subjects were divided into two groups: the "immersion only" (IO) group had no additional injuries associated with their immersion-related events, while subjects in the "associated injury" (AI) group incurred additional trauma during injury events. Results: There were 176 ATR records of nonfatal immersion events. In 87 (49.5%) cases, hospitalizations were due to the effects of immersion only (IO group). In 89 (50.5%) cases, hospitalizations were due not only to the effects of immersion, but also due to additional injuries occurring immediately before or while immersion took place (AI group). The final logistic regression model revealed statistically significant relationships between age greater than 12 years, female gender, white ethnicity, and operation of water transport vehicles, and increased risk for associated injury outcomes (p < 0.05). Discussion: This study is the first of its kind to analyze factors associated with the most severe nonfatal immersion-related injuries in Alaska, and identifies target populations for future safety campaigns. © 2005 Elsevier Ltd.

- The use of capillary electrophoresis with laser-induced fluorescence detection (CE-LIF) for the analysis of microdialysate samples from the periaqueductal grey matter (PAG) of freely moving rats is described. By employing 3-(4-carboxybenzoyl)-2-quinoline-carboxaldehyde (CBQCA) as a derivatization agent, we simultaneously monitored the concentrations of 8 amino acids (arginine, glutamine, valine, gamma-amino-n-butyric acid (GABA), alanine, glycine, glutamate, and aspartate), with nanomolar and subnanomolar detection limits. Two of the amino acids (GABA and glutamate) were analysed in parallel by conventional high-performance liquid chromatography (HPLC) in order to directly compare the two analytical methods. Other CE methods for analysis of microdialysate have been previously described, and this improved method offers greater sensitivity, ease of use, and the possibility to monitor several amino acids simultaneously. By using this technique together with an optimised form of microdialysis technique, the tiny sample consumption and the improved detection limits permit the detection of fast and transient transmitter changes.

- The cell nucleus plays an essential role in all aspects of cell function and regulation. Most of the nuclear proteins/peptides are synthesized in the cytoplasm and transported into the nucleus through the nuclear pore complexes. The nuclear proteins/peptides conjugate with each other and interact in transcriptional activation/inactivation. Several of the high molecular mass transcription factors (> 30 kDa) have been identified and characterized. However, the information on the low molecular mass proteins/peptides of the nucleus is limited. We have investigated these low molecular mass proteins/peptides from the nucleus of human peripheral blood lymphocytes using reversed-phase high-performance liquid chromatography (RP-HPLC). The HPLC fractions were further analysed by matrix assisted laser desorption/ionization time of flight (MALDI-TOF) mass spectrometry, electrospray ionization time of flight (ESI-TOF) mass spectrometry and electrospray ionization fourier transform ion cyclotron resonance (ESI-FTICR) mass spectrometry for mass determination. Using this combination of mass spectrometry techniques and microsequence analysis, we have shown that human lymphocyte nuclei contain defensins, a mixture of human neutrophil granule peptide 1, 2 and 3.

Plasma neuropeptides in hyperthyroidism

Tidskriftsartikel (refereegranskat)abstract
- Plasma levels of the neuropeptides, vasoactive intestinal polypeptide (VIP, neuropeptide Y (NPY), calcitonin gene-related peptide (CGRP), substance P, and galanin were determined in 15 hyperthyroid patients before and at 3 occassions during 38 weeks of treatment. Treatment was performed with either 131I alone or with carbimazole, with combination of carbimazole and thyroxine, or with subtotal thyroidectomy. Before and after 11 (+/- 4), 24 (+/- 6) and 38 (+/- 5) weeks of treatment, plasma neuropeptide levels were analysed. A group of 9 premenopausal women served as controls. During hyperthyroidism, mean plasma level of CGRP was higher than in controls (P less than 0.001). In contrast, the mean plasma levels of the other measured neuropeptides did not differ from those in the controls. Mean serum level of tree T4 was lowered from 81.9 +/- 30.1 to 23.9 +/- 8.6 pmol/l and mean serum level of free T3 was lowered from 27.3 +/- 7.9 to 6.7 +/- 2.3 pmol/l during the course of the treatment. After 11 weeks of treatment, mean plasma NPY level was significantly increased (P = 0.004) compared to pretreatment levels. However, after 38 weeks of treatment, mean plasma NPY level had returned to control values. The mean plasma CGRP level was significantly reduced at 11 and 38 weeks of treatment compared to pre-treatment value (P = 0.002 and P = 0.004, respectively). Mean plasma level of neurotensin slowly declined during the treatment (P = 0.003). In contrast, mean plasma level of VIP, of substance P, and of galanin did not differ from control value before or after treatment.(ABSTRACT TRUNCATED AT 250 WORDS)
