An approach to membrane computing under inexactitude [PDF]
arXiv, 2004 In this paper we introduce a fuzzy version of symport/antiport membrane systems. Our fuzzy membrane systems handle possibly inexact copies of reactives and their rules are endowed with threshold functions that determine whether a rule can be applied or not to a given set of objects, depending of the degree of accuracy of these objects to the reactives ...

Frontiers in Physiology, 2017 The peptide transporter (PepT) systems are well-known for their importance to protein absorption in all vertebrate species. These symporters use H+ gradient at the apical membrane of the intestinal epithelial cells to mediate the absorption of small ...

Photochemistry and Photobiology, EarlyView.Through mRNA sequencing, proteomics, and flow cytometry, we identified potential cell surface targets toward tumor‐targeted, activatable photoimmunotherapy (taPIT) in advanced high‐grade serous ovarian cancers (HGSOCs) with low EGFR expression. The reliance on EGFR overexpression has been a major limitation of taPIT, which this study seeks to address ...

Quantum Theory on Glucose Transport Across Membrane [PDF]
arXiv, 2014 After a brief review of the protein folding quantum theory and a short discussion on its experimental evidences the mechanism of glucose transport across membrane is studied from the point of quantum conformational transition. The structural variations among four kinds of conformations of the human glucose transporter GLUT1 (ligand free occluded ...

Dapagliflozin stimulates glucagon secretion at high glucose: experiments and mathematical simulations of human A-cells. [PDF]
, 2016 Glucagon is one of the main regulators of blood glucose levels and dysfunctional stimulus secretion coupling in pancreatic A-cells is believed to be an important factor during development of diabetes.

A comparative study of structures and structural transitions of secondary transporters with the LeuT fold [PDF]
, 2018 Secondary active transporters from several protein families share a core of two five-helix inverted repeats that has become known as the LeuT fold. The known high-resolution protein structures with this fold were analyzed by structural superposition of ...

Molecular Dynamics Simulations of a Putative Novel Mechanism for UCP1‐Assisted FA Anion Transport
Acta Physiologica, Volume 241, Issue 7, July 2025.ABSTRACT Background Mitochondrial energy can be stored as ATP or released as heat by uncoupling protein 1 (UCP1) during non‐shivering thermogenesis in brown adipose tissue. UCP1, located in the inner mitochondrial membrane, reduces the proton gradient in the presence of long‐chain fatty acids (FA).

Identification of a sodium-bicarbonate symport in human platelets
Biochimica et Biophysica Acta (BBA) - Biomembranes, 1996 Intracellular pH (pH(i)) was measured in human platelets using fluorescent probes. Basal pH(i) was higher in HC(O3-)- buffered solutions (7(7.33 +/- 0.01) than in nominally HCO3- free, Hepes buffered solutions (7.16 +/- 0.01, P < 0.05). Addition of EIPA caused to fall in Hepes, but did not inhibit the increase of pH(i) when platelets maintained in ...

MFS transportome of the human pathogenic yeast
BMC Genomics, 2008 Background The major facilitator superfamily (MFS) is one of the two largest superfamilies of membrane transporters present ubiquitously in bacteria, archaea, and eukarya and includes members that function as uniporters, symporters or antiporters.
