Differential vitellin polypeptide processing in insect embryos
Abstract This review focuses on the current status of knowledge regarding the process of vitellogenin (Vg) uptake and vitellin (Vt) storage in insect oocytes. We also consider the overall morphologyExpand

Paired Activation of Two Components within Muscarinic M3 Receptor Dimers Is Required for Recruitment of β-Arrestin-1 to the Plasma Membrane*
β-Arrestins regulate the functioning of G protein-coupled receptors in a variety of cellular processes including receptor-mediated endocytosis and activation of signaling molecules such as ERK. A keyExpand

Resting smooth muscle cells as a model for studying vascular cell activation.
Vascular smooth muscle (VSM) cells constitute the main structural components of tunica media. Under physiological conditions, these cells display a contractile phenotype and a low proliferativeExpand

  • 1 December 2015
We introduce a framework that considers the heterarchical embeddedness of different layers of physiological, behavioral, affective, cognitive, technological and socio-cultural levels implicit in networks of interacting minds, considering the dynamic complementarity of bottom-up and top-down causal links.

Thyroid disruptor 1,1,1-trichloro-2,2-bis(p-chlorophenyl)ethane (DDT) prevents internalization of TSH receptor
The thyroid-stimulating hormone (TSH) receptor (TSHr) was made specifically fluorescent by insertion of a tetracysteine motif (TSHr-FlAsH) into the C-terminal end and transiently transfected intoExpand

Development of gap junctions in normal and mutant ovaries of Drosophila melanogaster
An ovarian follicle of Drosophila consists of an oocyte, 15 nurse cells, and hundreds of follicular epithelial cells. A freeze‐fracture analysis of the surfaces between glutaraldehyde‐fixed ovarianExpand

Presence of a putative steroidal allosteric site on glycoprotein hormone receptors.
In a previous work we found that the insecticide 1,1,1-trichloro-2,2-bis(p-chlorophenyl)ethane (DDT), inhibits the accumulation of cAMP as induced by the bovine thyroid stimulating hormone (bTSH) inExpand

Yolk granules are differentially acidified during embryo development in the stick insect Carausius morosus
Abstract. Newly laid eggs of stick insects comprise a unique fluid ooplasm that is gradually partitioned into a number of yolk granules by invasion of secondary vitellophages. This study aimed atExpand

Microvesicles shed from fibroblasts act as metalloproteinase carriers in a 3-D collagen matrix
This study shows that fibroblasts migrating into a collagen matrix release numerous microvesicles into the surrounding medium. By spreading in regions of the matrix far distant from cells of origin,Expand
