Low levels of G17 and Barrett esophagus: a clinical relationship

Clinical Chemistry and Laboratory Medicine, 2022
Background & Aims: In clinical practice, most patients with symptoms suggestive of gastroesophageal reflux disease (GERD) undergo esophago-gastro-duodenoscopy (EGD), despite its low sensitivity in detecting reflux stigmata. Gastrin 17 (G-17) has been proposed to be related with GERD, due to the negative feedback between acid secretion and this hormone.

Ozonolysis of Asphaltenes from Semicoking Tar of G17 Coal

Russian Journal of Applied Chemistry, 2003
Liquid-phase ozonolysis of asphaltenes from the semicoking tar of G17 coal was studied. In structural studies of asphaltenes, ozone is of particular interest as a specific agent cleaving double bonds [139]. Identification of low-molecular-weight (water-soluble) and high-molecular-weight (waterinsoluble) products of asphaltene ozonolysis by 1H and 13C ...

Effects of pentagastrin, G17, and G34 on the electrical and mechanical activities of canine antral smooth muscle

Gastroenterology, 1978
Intracellular microelectrode technique and standard organ bath technique were used to investigate the effects of pentagastrin, G17, and G34 on the electrical and mechanical activities of canine antral circular muscle. All three molecular forms increased the amplitude and duration of the plateau of the gastric action potential and the frequency of ...

ELKONITES G17, G18, 7065, 7165

Alloy Digest, 2001
Abstract ELKONITE G17, G18, 7065, and 7165 silver silver alloys contain molybdenum as the refractory metal. Molybdenum has a lower density than tungsten and is less resistant to arc erosion. Molybdenum-silver Elkonites exhibit self-cleaning properties when subjected to arching during switching. The arc breaks down the molybdenum oxide at

Hb Madrid [β115(G17)Ala→Pro] in a Korean Family with Chronic Hemolytic Anemia

Hemoglobin, 2000
Hb Madrid, in which the alanine residue at beta115 (G17) is replaced by proline, results in a moderately severe hemolytic anemia due to the disruption of an alpha helical region and the weakening of an alpha1 beta1 contact (1,2). It was first discovered in a single Spanish patient, by protein structural analysis, whose parents did not carry the ...

Haemoglobin Madrid β115 (G17) Alanine→Proline: an Unstable Variant Associated with Haemolytic Anaemia

Acta Haematologica, 2009
A new unstable haemoglobin, Hb Madrid (β115 [G17] Ala →·Pro), has been found in a Spanish boy suffering from a moderately severe haemolytic anaemia. This haemoglobin is the eighth example of haemoglobin instability resulting from insertion of a proline residue into a helical segment of the globin chain.
