We present a comprehensive study of the gas kinematics associated with density structures at different spatial scales in filamentary infrared dark cloud, G034.43+00.24 (G34). This makes use H13CO+ (1-0) molecular line data from ALMA Three-millimeter Observations Massive Star-forming regions (ATOMS) survey, which has and velocity resolution 0.04 pc 0.2 km/s, respectively. Several tens dendrogram...

The M2 protein of influenza A virus forms a transmembrane proton channel important for viral infection and replication. Amantadine blocks this channel, thus inhibiting viral replication. Elucidating the high-resolution structure of the M2 protein and its change upon amantadine binding is crucial for designing antiviral drugs to combat the growing resistance of influenza A viruses against amanta...

. This paper tests the hypothesis that the threat of a contested takeover improves corporate performance. This is done by a cross-sectional analysis of listed Danish firms with and without effective takeover defenses. Takeover defenses adopted by Danish firms mainly consist of dual class voting rights often in combination with foundation ownership. Using simultaneous equation estimation to deal...

The article studies how takeover defenses influence managerial incentives with respect to long term investments, excess liquidity and the amount of debt relative to equity. The article conducts a cross-sectional regression based on a sample of Danish listed firms, dealing explicitly with the problem of causation between the variables. Takeover defenses adopted by Danish firms mainly consist of ...

BACKGROUND Gastric acid is the most important pathophysiologic determinant in the development of peptic ulcer diseases, and gastrin and somatostatin are believed to be physiologic hormonal regulators in gastric acid secretion. The aim of this study is to investigate patterns of these peptides, both in serum and in tissue, and to correlate with numbers of their secretory cells in the antral and ...

Helicobacter pylon infection increases the serum concentration of gastrin, and this may be one of the mechanisms by which it predisposes to duodenal ulceration. Different forms of circulating gastrin were studied both basally and postprandially in 13 duodenal ulcer patients before and one month after eradication of H pylon. Three antisera that are specific for particular regions of the gastrin ...

Recent studies on the gene sequence encoding the human pyloric antral hormone, gastrin, indicate a precursor of 101 residues. We have now raised antibodies to a synthetic analogue corresponding to (Tyr)-human progastrin COOH-terminal pentapeptide. The antibodies could be used in radioimmunoassay to measure this peptide, but they did not react with corresponding fragments of procholecystokinin, ...
