Estimation of Leptin and Leptin Receptor Concentrations in Seminal Plasma of Primary Infertile Men

open access: yesمجلة كلية الطب, 2017
Background: There are many sources for Leptin secretion, and it is activated by binding with its receptor known as leptin receptor, that play a role in male infertility.

Receptor-Mediated Transcytosis of Leptin through Human Intestinal Cells In Vitro

open access: yesInternational Journal of Cell Biology, 2010
Gastric Leptin is absorbed by duodenal enterocytes and released on the basolateral side towards the bloodstream. We investigated in vitro some of the mechanisms of this transport.

Steroid Receptors and Vertebrate Evolution [PDF]

open access: yesarXiv, 2019
Considering that life on earth evolved about 3.7 billion years ago, vertebrates are young, appearing in the fossil record during the Cambrian explosion about 542 to 515 million years ago. Results from sequence analyses of genomes from bacteria, yeast, plants, invertebrates and vertebrates indicate that receptors for adrenal steroids (aldosterone ...

Cellular mechanisms underlying the effects of an early experience on cognitive abilities and affective states

open access: yesAnnals of General Psychiatry, 2005
In the present study we investigated the effects of neonatal handling, an animal model of early experience, on spatial learning and memory, on hippocampal glucocorticoid (GR), mineralocorticoid (MR) and type 1A serotonin (5-HT1A) receptors, as well as ...

Accuracy of direct gradient sensing by cell-surface receptors [PDF]

open access: yesarXiv, 2009
Chemotactic cells of eukaryotic organisms are able to accurately sense shallow chemical concentration gradients using cell-surface receptors. This sensing ability is remarkable as cells must be able to spatially resolve small fractional differences in the numbers of particles randomly arriving at cell-surface receptors by diffusion.

The Role of Leptin in Antipsychotic-Induced Weight Gain: Genetic and Non-Genetic Factors

open access: yesJournal of Obesity, 2012
Schizophrenia is a chronic and disabling mental illness affecting millions of people worldwide. A greater proportion of people with schizophrenia tends to be overweight.

Chemical sensing by cell-surface chemoreceptor arrays: the roles of receptor cooperativity and adaptation [PDF]

open access: yesarXiv, 2012
Most sensory cells use cross-membrane chemoreceptors to detect chemical signals in the environment. The biochemical properties and spatial organization of chemoreceptors play important roles in achieving and maintaining sensitivity and accuracy of chemical sensing.
