Taste receptor polymorphisms and longevity: a systematic review and meta-analysis
2020
AbstractBitter taste receptors (TAS2R) are involved in a variety of non-tasting physiological processes, including immune-inflammatory ones. Therefore, their genetic variations might influence various traits. In particular, in different populations of South Italy (Calabria, Cilento, and Sardinia), polymorphisms of TAS2R16 and TAS238 have been analysed in association with longevity with inconsistent results. A meta-analytic approach to quantitatively synthesize the possible effect of the previous variants and, possibly, to reconcile the inconsistencies has been used in the present paper. TAS2R38 variants in the Cilento population were also analysed for their possible association with longevi…
Sobre cerámicas Helenísticas en Iberia / Hispania. Significado y funcionalidad
2012
In this work we are going to take a chronological and typological tour by studying the iconography that appears in the Hellenistic wares imported from the Central and Oriental Mediterranean between 3rd and 2nd centuries BC in Hispania Citerior, in particular from Cartagena. We are going to analyze its functionality in the places of origin, and with the help of the Hispanic contexts we will conclude whether its presence here is a consequence of a certain commercial dynamic, or if it answers to a decorative preference, of taste or trend; even if the images are significant related to ritual or convivial uses, public or private, by the local inhabitant who acquires and uses them.
The role of contact chemoreception in the host location process of an egg parasitoid
2016
Taste allows insects to detect palatable or toxic foods, identify a mate, and select appropriate oviposition sites. The gustatory system strongly contributes to the survival and reproductive success of many species, yet it is rarely studied in insect parasitoids. In order to locate and assess a host in which they will lay their eggs, female wasps actively search for chemical cues using their sensory organs present mainly on the antennae. In this paper, we studied the role of antennal taste sensilla chaetica in the perception of contact semiochemicals in Trissolcus brochymenae (Hymenoptera: Platygastridae), an egg parasitoid of the brassicaceae pest Murgantia histrionica (Heteroptera: Pentat…
De la visión y el espanto : el tacto suspendido y la experiencia ante el límite
2017
En la pintura del pintor bogotano Epifanio Garay (1849-1903), “La mujer del Levita”, la fascinación y el espanto entran en escena. El acto representado da pie para formular un diálogo con lo que sugería Pascal Quignard cuando decía que para los romanos “el sexo estaba ligado al espanto”. A partir de esta premisa, las próximas páginas se proponen dialogar con todo aquello que para los antiguos prefiguraba la interdicción ante todo cadáver: “no tocar”. Sin embargo, se verá que todo se juega en el momento en que, en la escena de la pintura, el tacto se suspende y la prohibición es puesta en suspenso. La mirada del horror, la mirada tautológica, los ojos del éxtasis, son algunos de los canales …
Vidzemes Lielais Zviedru Kadastrs kā saimniecības vēstures avots
1942
Kadastrs - sistematizēti kādu zemes vai ūdens nogabalu vai citu objektu dati; ar nodokļiem apliekamo zemju saraksts un novērtējums pilsētās un laukos. Zemes kadastru sāka ar zemes uzmērīšanu un vērtēšanu, vienlaikus veicot muižu redukciju, atsavinot lielāko daļu muižas zemju, kuras nodeva Zviedrijas valsts pārziņā. Tas bija labi izstrādāts kadastrs, un to izmantoja no 1691. līdz 1911. gadam, t. i., 220 gadus. Tas pasaulē ir samērā mazpazīstams, un tagadējās Latvijas un Igaunijas teritorijā tam bija tikai lokāla nozīme. Muižu redukcija .17. gs. 2. pusē, pieaugot absolūtisma tendencēm Eiropā, Zviedrijas karalis Kārlis XI (Karl XI) centās nostiprināt varu visā valstī. Viens no pasākumiem bija …
Variability in bitter taste perception and correlation with SNP in TAS2R38 gene in different student population
2007
People vary widely in their sensitivities to bitter compounds. The PTC gene, TAS2R38 on chromosome 7, consists a single coding exon which encodes a G-protein-coupled receptor. The taster subject contains a proline at position 49, an alanine at position 262. and a valine at position 296 (PAV form), while the no taster contains an alanine, a valine, and an isoleucine at these 3 positions, respectively (AVI form).These two forms depend on three single nucleotide polymorphisms (SNP). By providing students with paper soaked in different solutions of PTC it was been possible to assess the individual threshold of bitterness sensitivity. DNA was extracted from saliva, and following PCR amplification…
Asperuloside Enhances Taste Perception and Prevents Weight Gain in High-Fat Fed Mice
2021
Asperuloside is an iridoid glycoside found in many medicinal plants that has produced promising anti-obesity results in animal models. In previous studies, three months of asperuloside administration reduced food intake, body weight, and adipose masses in rats consuming a high fat diet (HFD). However, the mechanisms by which asperuloside exerts its anti-obesity properties were not clarified. Here, we investigated homeostatic and nutrient-sensing mechanisms regulating food intake in mice consuming HFD. We confirmed the anti-obesity properties of asperuloside and, importantly, we identified some mechanisms that could be responsible for its therapeutic effect. Asperuloside reduced body weight …
Bile acid receptor TGR5 is critically involved in preference for dietary lipids and obesity
2020
International audience; We investigated the implication of Takeda G protein-coupled receptor 5 (TGR5) in fat preference and fat sensing in taste bud cells (TBC) in C57BL/6 wild-type (WT) and TGR5 knock out (TGR5-/-) male mice maintained for 20 weeks on a high-fat diet (HFD). We also assessed the implication of TGR5 single nucleotide polymorphism (SNP) in young obese humans. The high-fat diet (HFD)-fed TGR5-/- mice were more obese, marked with higher liver weight, lipidemia and steatosis than WT obese mice. The TGR5-/- obese mice exhibited high daily food/energy intake, fat mass and inflammatory status. WT obese mice lost the preference for dietary fat, but the TGR5-/- obese mice exhibited n…
Obesity interferes with the orosensory detection of long-chain fatty acids in humans
2014
Background: The association between the orosensory detection of lipids, preference for fatty foods, and body mass index (BMI; in kg/m 2 ) is controversial in humans. Objective: We explored the oral lipid-sensing system and the orosensory-induced autonomic reflex system in lean and obese subjects. Design: Lean (BMI: 19 to ,25; n = 30) and obese (BMI .30; n = 29) age-matched men were enrolled. Their oral threshold sensitivity to linoleic acid (LA) was determined by using a 3-alternative forced-choice ascending procedure, and their eating habits were established by the analysis of 4 consecutive 24-h food-consumption diaries. The effect of brief oral lipid stimulations on plasma triglyceride [(…
Evolution of microbiological and chemical parameters during red wine making with extended post-fermentation maceration.
2014
Abstract The aim of the present work was to investigate the microbiological, chemical, and sensory characteristics of red wine subjected to post-fermentation maceration that was extended to 90 days. For this purpose, the ‘Aglianico di Taurasi’ grape was used as a case study. The total yeast concentration increased until day 40 of maceration and decreased thereafter, whereas the concentration of lactic acid bacteria slightly increased. Dekkera/Brettanomyces spp. and acetic acid bacteria were not detected. The yeast community was composed of Saccharomyces cerevisiae, Zygosaccharomyces bisporus, Metschnikowia pulcherrima, Hanseniaspora guilliermondii, Hanseniaspora uvarum, Pichia guilliermondi…
