Gastrinoma de localização pilórica numa doente com úlcera péptica recorrente.

open access: yesActa Médica Portuguesa, 1992
We report a clinical case of a woman, 56 years old, with a history of duodenal ulcer and esophagitis, under medication with H2 receptors blockers during 3 years. Plasma basal gastrin was near normal levels. A stimulation test with secretin was compatible

Etiology and pathogenesis of duodenal mucosa lesion in chronic pancreatitis

open access: yesТерапевтический архив, 2009
Aim. To measure content of neuromediators (acetylcholine - Ach, serotonin - 5-NT) and gastrointestinal hormones (cholecystokinine - CCK and secretin) in the blood serum of patients with chronic pancreatitis (CP); to study protective properties of the ...

Assembly of the type II secretion system such as found in Vibrio cholerae depends on the novel Pilotin AspS.

open access: yesPLoS Pathogens, 2013
The Type II Secretion System (T2SS) is a molecular machine that drives the secretion of fully-folded protein substrates across the bacterial outer membrane.

Architecture of the type IVa pilus machine [PDF]

open access: yes, 2016
Many bacteria, including important pathogens, move by projecting grappling-hook–like extensions called type IV pili from their cell bodies. After these pili attach to other cells or objects in their environment, the bacteria retract the pili to pull ...

Structure of a type IV pilus machinery in the open and closed state

open access: yeseLife, 2015
Proteins of the secretin family form large macromolecular complexes, which assemble in the outer membrane of Gram-negative bacteria. Secretins are major components of type II and III secretion systems and are linked to extrusion of type IV pili (T4P) and

Structural and functional divergence of growth hormone-releasing hormone receptors in early sarcopterygians: lungfish and Xenopus [PDF]

open access: yes, 2013
The evolutionary trajectories of growth hormone-releasing hormone (GHRH) receptor remain enigmatic since the discovery of physiologically functional GHRH-GHRH receptor (GHRHR) in non-mammalian vertebrates in 2007.

Biliary Bicarbonate Secretion Constitutes a Protective Mechanism against Bile Acid-Induced Injury in Man [PDF]

open access: yes, 2011
Background: Cholangiocytes expose a striking resistance against bile acids: while other cell types, such as hepatocytes, are susceptible to bile acid-induced toxicity and apoptosis already at micromolar concentrations, cholangiocytes are continuously ...
