What's the difference between membrane and subperitoneal?

Membrane


Definition:

  • (n.) A thin layer or fold of tissue, usually supported by a fibrous network, serving to cover or line some part or organ, and often secreting or absorbing certain fluids.

Example Sentences:

  • (8) Apparently, the irradiation with visible light of a low intensity creates an additional proton gradient and thus stimulates a new replication and division cycle in the population of cells whose membranes do not have delta pH necessary for the initiation of these processes.
  • (9) Using monoclonal antibodies directed against the plasma membrane of Madin-Darby canine kidney (MDCK) cells, we demonstrated previously that a glycoprotein with an Mr = 23,000 (gp23) had a non-polarized cell surface distribution and was observed on both the apical and basolateral membranes (Ojakian, G. K., Romain, R. E., and Herz, R. E. (1987) Am.

  • (11) Together these results suggest that IVC may operate as a selective activator of calpain both in the cytosol and at the membrane level; in the latter case in synergism with the activation induced by association of the proteinase to the cell membrane.
  • (12) The Cole-Moore effect, which was found here only under a specific set of conditions, thus may be a special case rather than the general property of the membrane.
  • (13) We have examined the insertion of bovine 17 alpha-hydroxylase (P45017 alpha) into the endoplasmic reticulum of COS 1 cells to evaluate the functional role of its hydrophobic amino-terminal sequence and membrane insertion.

  • (16) Extensive studies during recent years have shown that the interaction between hormone and membrane-bound receptor can affect the receptor characteristics in at least two ways.
  • (17) Membranes of this material were filled with islets of Langerhans and implanted in the peritoneal cavity of rats.
  • (18) The penicillin-resistant Enterococcus hirae R40 has a typical profile of membrane-bound penicillin-binding proteins (PBPs) except that the 71 kDa PBP5 of low penicillin affinity represents about 50% of all the PBPs present.
  • (19) To investigate the mechanism of enhanced responsiveness of cholesterol-enriched human platelets, we compared stimulation by surface-membrane-receptor (thrombin) and post-receptor (AlF4-) G-protein-directed pathways.
  • (20) Moreover, in DCVC-treated cells the mitochondria could not be stained with rhodamine-123, indicating severe mitochondrial damage and loss of membrane potential.

Subperitoneal


Definition:

  • (a.) Situated under the peritoneal membrane.

Example Sentences:

  • (1) The single space thus created allows the wide implantation of a subperitoneal Mersilene prosthesis which is isolated from the viscera as well as from the skin.

  • (5) The results support the existence of unrecognized subperitoneal and microscopic surface endometriosis.
  • (6) The credit for this specific feature of our short series may be due to an exclusively subperitoneal approach for both the pancreas and the kidney transplantation, thus limiting the seriousness of postoperative infectious complications to a large extent.
  • (7) Today the cause of LPD is seen in a specific hormonal stimulation of the pluripotent subperitoneal mesenchyma of the müllerian duct in the minor pelvis.
  • (8) Twice the cervical portion of the oesophagus was perforated, once the lower thoracic portion and once subperitoneal perforation in hiatus hernia was involved.
  • (9) We believe, in contrast, that LPD is a benign reparative process in which fibroblasts replace subperitoneal decidua.
  • (10) Three cases of traumatic rupture of a subperitoneal hollow viscus are reported : two duodenal lesions and one rectal wound.
  • (11) The authors report about the observation of a subperitoneal pelvic cystic lymphangioma in an adult patient: ultrasound and CT dat had yet never been described for the rare pelvic form, and are the same as with the other locations of cystic lymphangioma in adults.
  • (12) Chronic pelvic congestion syndrome or fibrous congestion is linked with fibrous changes of the subperitoneal cellular tissue after more or less lasting chronic congestion.
