• On an interesting note, when the temperatures get higher fleas do not have their proventriculus blocked, and only those that are blocked can transmit the disease. (kenyon.edu)
  • Since the dve -expressing anterior-most midgut constitutes the outer layer of the proventriculus, this dve phenotype suggests that dve activity is required for the functional development of outer layer cells and the consequent retention of the internal portion of the proventriculus.

  • Histopathological lesions were observed in the esophagus, proventriculus, ventriculus, and duodenum of SAMW-treated mallards, with the most distinctive being erosion and ulceration of the kaolin of the ventriculus, ventricular hemorrhage and/or congestion, and duodenal hemorrhage. (usgs.gov)
  • They are cytosolic and expressed throughout the parasite cycle with the exception of the stages found in the tsetse fly proventriculus, as shown by both immunofluorescence and live cell analysis upon endogenous tagging with YFP. (uni-wuerzburg.de)
  • Knock-down of both proteins in the developmental stage preceding these forms leads to striking modifications: cell elongation, cell cycle arrest and relocalization of the nucleus in a posterior position, all typical of processes acting in parasites found in the proventriculus region.
