“…Regarding all these opinions, it seems that the main attributes that consumers look for are colour, fat 294 content and price. As will be discussed later, this is in agreement with the results obtained in the 295 face-to-face surveys at butcheries and is in line with attributes discussed in literature (Font i Furnols 296 and Guerrero, 2014; Kallas et al, 2012). 297…”

“…Other 384 questions in the survey showed that butchers prefer and buy mostly meat from female pigs, and that 385 fat content (intramuscular fat content in particular) and colour of the meat are also important for 386 butchers and consumers. Previous studies by Kallas et al (2012) showed the relative importance of 387 pig meat attributes for Spanish consumers: taste and odour (56.76%), price (20.96%), origin (16.32%) 388 and pig gender (5.90%). Regarding these results, the relative importance of origin was similar for 389 both, butchers and consumers, but there was a difference of criteria about pig gender, it is important 390 for butchers whilst it seems that consumers did not take so much care about it.…”

“…To tackle this issue, we first relied on prior 142 research performed on fresh pig meat (Font i Furnols and Guerrero, 2014; Kallas et al, 2012). The 143 attributes identified from the literature were discussed in the applied focus groups.…”

“…Previous studies have assessed consumers' opinion and the relative 75 importance of pig castration (Kallas et al, 2013;Kallas et al, 2012). In order to evaluate whether 76 commercialization of boar meat would be a problem, it was considered useful to know if the meat 77 industry, retailers, consumers and exportation would be able to accept the change from meat from 78 castrated pigs to meat from entire males.…”

19Castration in pig production is mainly performed to avoid boar taint and for management purposes. 20The European Commission plans to end voluntarily surgical piglet castration by 2018. The aim of this 21 study was to assess the opinions and attitudes of Spanish stakeholders from the whole pork chain 22 regarding this plan. Two methodologies were used: focus groups with 26 participants (qualitative 23 method) were carried out with representatives of farmers, the meat industry, government 24 institutions, retailers (including butchers), HORECA and consumers; and 127 face-to-face surveys to 25 butcheries (quantitative method) were carried out, including an analytical hierarchical process to 26 assess the determining factors when purchasing fresh pig meat. Results showed that a potential end 27 of pig castration in Europe is not considered to have an effect on conventional pig production in 28

Odorant Receptor 7D4 Activation Dynamics

et al. 2018

Deciphering how an odorant activates an odorant receptor (OR) and how changes in specific OR residues affect its responsiveness are central to understanding our sense of smell. Aj oint approach combining site-directed mutagenesis and functional assays with computational modeling has been used to explore the signaling mechanics of OR7D4. In this OR, ag enetic polymorphism affects our perception of androstenone.M olecular simulations totaling 0.12 ms predicted that, similarly to observations for other G-protein-coupled receptors with knowne xperimental structures,a na ctivation pathway connects the ligand and the G-protein binding site.T he 3D model activation mechanism correlates with in vitro data and notably predicts that the OR7D4 WM variant is not activated. Upon activation, an OR-specific sequence motif is the convergence point of the mechanism. Our study suggests that robust homology modeling can serve as ap owerful tool to capture OR dynamics related to smell perception.Our sense of smell is triggered by the activation of odorant receptors (ORs) expressed on the surface of olfactory sensory neurons.Smelling relies on aso-called combinatorial code of OR activations. [1] Our approximately 400 ORs endow us with spectacular discriminatory power. ORs represent more than 3% of our protein-coding genes and belong to the class AGprotein-coupled receptor (GPCR) family.S tructurally, class AGPCRs are made up of seven transmembrane helices (TMs), named TM1 to TM7, which form abundle within the cell membrane.U pon activation, an allosteric signal is transmitted from the ligand to the G-protein binding site over ad istance of more than 20 (ca. 5h elix turns). [2] The intracellular part of TM6 then tilts outward with respect to its position in the inactive state. [3] Mammalian OR sequences show ah ighly conserved and OR-specific RxKAFSTCxSH motif in the intracellular part of TM6, suggesting acrucial role in the control of OR activation. In non-olfactory class AG PCRs,o nly the second lysine residue is conserved. [4] Odorant-receptor-activation dynamics still remain to be uncovered, but as ignificant body of work has focused on the molecular details of OR activation, especially concerning the interaction between ORs and ligands. [5] Thes trength of molecular-modeling approaches on GPCRs was demonstrated by ag roundbreaking study based on homology modeling and virtual screening, which deorphanized GPR68 and GPR65. [6] By applying this approach to ORs,w er ecently demonstrated how certain mutations alter receptor function or dynamics. [4,7] Human OR7D4, which is narrowly tuned to detect the testosterone metabolites androstadienone and androstenone, is as pectacular example of how natural sequence variations can affect activation and subsequent odor perception. People with two copies of the most common genetic variant (OR7D4-RTorw ild type,w t) tend to describe the androstenone smell as sickening,putrid, foul, or urine-like.However, people who possess the unresponsive R88W/T133M variant (OR7D4-WM) tend to report the smell to...
