There is a scarcity of work examining the relationship between culture and pain-related caregiver behaviors. Moreover, no pediatric pain studies have examined the relationship between caregiver cultural values and pain-related caregiver behaviors nor discern if this process is mediated by caregiver parenting styles and moderated by ecosocial context. Based on cross-cultural developmental theories,

In this work, we propose to utilize a recently developed covariance matrix interpolation technique in order to improve noise reduction in multi-microphone setups in the presence of a moving, localized noise source. Based on the concept of optimal mass transport, the proposed method induces matrix interpolants implying smooth spatial displacement of the noise source, allowing for physically reasona

The human B1 bradykinin (BK) receptor (B1R) is more efficacious than the human B2 BK receptor (B2R) in both ligand-independent and agonist-dependent coupling to Gq/11-mediated phospholipase Cβ activity. In fact, B1R is constitutively active, whereas B2R exhibits little if any constitutive activity. To evaluate the role of the C-terminal domain in receptor Gq/11 coupling, we constructed chimeric an

In this report, we show that desensitization regulates ligand- independent, spontaneous activity of the human B2 bradykinin (BK) receptor, and the level of spontaneous receptor activity determines the action of the BK antagonists and partial receptor agonists NPC17731 and HOE140 as agonists or inverse agonists. Spontaneous receptor activity was monitored by measuring basal cellular phosphoinositid

Elevated formation of bradykinin (BK) and Lys-BK or kallidin (KD) and their carboxypeptidase metabolites desArg9BK and desArg10KD is evident at sites of inflammation. Moreover, B2 receptors (B2R) which mediate the action of BK and KD, participates in the acute stage of the inflammatory and pain response, whereas B1 receptors (B1R), through which desArg9BK and desArg10KD act, partake in the chronic

In order to identify agonist- and antagonist-binding epitopes in the human B1 and B2 bradykinin (BK) receptors, we exploited the ability of these receptors to discriminate between peptide ligands that differ only by the absence (B1) grid presence (B2) of a C-terminal Arg. This was done by constructing chimeric proteins in which specific domains were exchanged between these receptors as recently de

The B1 and B2 bradykinin (BK) receptor subtypes belong to the GPCR faro ily, and they discriminate between peptides that differ only by the absence and presence of a C-terminal Arg, To identify receptor residues conferring tigand spe.cificity, chimeric constructs in which TM-III were exchanged between the receptors were expressed and assayed by radioligand binding and fluorescence Ca2+ imaging in

Caveolae are small flask-like invaginations on the plasma membrane that contain both G-proteins aim G-protein coupled receptors. Consequently, these structures have been implicated to serve a role in transmembrane signaling. Bradykinin (BK) is a potent vasoactive peptide that acts through B2 BK receptors to stimulate both Gaq and Gai. DDT1 MF2 smooth muscle cells were used to show that eaveolae co

In order to investigate the molecular basis for the ability of the human B1 and B2 bradykinin (BK) receptor subtypes to discriminate between subtype- selective ligands, we constructed chimeric proteins in which the sixth transmembrane domains (TM-VI) of these receptors were exchanged. The pharmacological profiles of the constructs were analyzed by radioligand binding in particulate preparations of

In this report, we show that the vasoactive peptide agonist bradykinin (BK) when bound to B2 BK receptors on DDT1 MF-2 smooth muscle cells promotes the recruitment and sequestration of the occupied receptors and the receptor- coupled G-protein α subunits Gα(q) and Gα(i) in caveolae. Association of ligand receptor complexes and Gα subunits with caveolae was indicated by their co-enrichment on densi

Artificiell intelligens bryter med invanda sätt att tänka kring å ena sidan objekt, ting, teknologiska artefakter och, å andra sidan, handlande subjekt. Somliga tänker rent av på artificiell intelligens som en ny form av liv. En sfär där artificiell intelligens står inför ett genombrott är i krig. Av förklarliga skäl finns starka åsikter om detta. Utvecklingen förkastas som innebärandes slutet på

The objective of this study was to probe the molecular mechanisms underlying the increase in sensitivity of cells to bradykinin (BK) following expression of a transforming Ha-ras oncogene. We used native NIH3T3 fibroblast (3T3) cells and 3T3 cells transfected with a glucocorticoid-sensitive oncogenic Ha-ras construct (DT cells). DT cells incubated in the presence of 1 μM dexamethasone (DEX) for 24
