Pro-enkephalin opioid peptides are abundant in porcine and bovine splenic nerves, but absent from nerves of rat, mouse, hamster, and guinea-pig spleen

1995

The opioidergic innervation of the mammalian spleen and possible species differences were investigated. Light-microscopic immunohistochemistry revealed that splenic nerves of bovine and porcine spleen, but not of rat, mouse, hamster and guinea-pig spleen contained proenkephalin-derived opioidergic innervation. Immunoreactivity to both prodynorphin and pro-opiomelanocortin was absent from splenic nerves. In bovine and porcine spleen, fibers immunoreactive for met-enkephalin, met-enkephalin-Arg-Phe, met-enkephalin-Arg-Gly-Leu, leu-enkephalin and peptide F formed perivascular plexus, traveled in trabecular connective tissue, and extended into the capsule. Spatial relationships with immune cell…

Recovery of Endogenous β-Cell Function in Nonhuman Primates After Chemical Diabetes Induction and Islet Transplantation

2008

OBJECTIVE—To describe the ability of nonhuman primate endocrine pancreata to reestablish endogenous insulin production after chemical β-cell destruction. RESEARCH DESIGN AND METHODS—Eleven monkeys (Macaca fascicularis) were rendered diabetic with streptozotocin. Eight diabetic monkeys received intraportal porcine islet transplantation. RESULTS—Two monkeys transplanted after 75 days of type 1 diabetes showed recovery of endogenous C-peptide production a few weeks after transplantation, concomitant with graft failure. Histological analysis of the pancreas of these monkeys showed insulin-positive cells, single or in small aggregates, scattered in the pancreas and adjacent to ducts. Interesting…

L'impact de l'information sur le résultat d'une vente aux enchères expérimentale de vin

2005

This paper reports the results of an experimental wine auction. Participants of the experiment were randomly assigned to three rooms. In each room four wines had to be evaluated, but the level of information to which participants had access differed across rooms. After the evaluations, the wines were sold sequentially, by four separate Vickrey auctions with secret reservation prices. We fi nd that certain socio-economic characteristics such as gender, income and consumption habits, have a signifi cant impact on the willingness to pay for wine, while others such as age and nationality, do not. We also fi nd that once individuals have read the label characteristics and extracts from wine guid…

La Route des Vins et l’émergence d’un tourisme viticole en Bourgogne dans l’entre-deux-guerres

2014

À la fin du XIXe siècle, les guides excluent totalement la gastronomie et la vigne des visites qu’ils proposent aux touristes de passage en Bourgogne. Seuls les sites naturels et les monuments historiques attirent l’attention des voyageurs. La gastronomie et le vin sont alors perçus et vendus comme des produits de luxe aristocratiques et internationaux – c’est-à-dire territorialement désincarnés. Le poids du négoce et sa liberté en termes de vinification (capacité d’assemblages de vins d’origines géographiques différentes) conditionnent amplement cette réalité. À la fin des années 1930, la transformation des normes de production et de commercialisation des vins en faveur d’un système d’appe…

Self-reported consumption of wine and other alcoholic beverages in a German wine area

2013

Petra Fronk,1 Maria Blettner,2 Heinz Decker1 1Institute for Molecular Biophysics, Johannes Gutenberg University of Mainz, Mainz, Germany; 2Institute for Medical Biostatistics, Epidemiology and Informatics, Johannes Gutenberg University of Mainz, Mainz, Germany Purpose: To describe the consumption of alcoholic beverages in a German wine area, with special attention to the number of people drinking more than the tolerable upper alcohol intake level (TUAL). Methods: A cross-sectional study was conducted using a mailed questionnaire, to investigate the weekly consumption of wine, beer, and spirits during the preceding 12 months in Mainz, the state capital of Rhineland-Palatinate, Germany. The a…

Non-Botrytis grape-rotting fungi responsible for earthy and moldy off-flavors and mycotoxins

2012

Abstract The grape microflora is complex and includes filamentous fungi, yeasts and bacteria with different physiological characteristics and effects on wine production. Most studies have focused on the wine microbiota, but a few studies have reported the ecology of grape microorganisms. Some of these organisms — such as non-Botrytis bunch rotting fungi, which greatly influence the safety or sensory quality of wine, due to the production of mycotoxins and off-flavors, respectively — are considered to be spoilage agents. We review here the diversity of filamentous fungi on grapes and the factors influencing their development, such as grape ripening stage, environmental factors (climate, rain…

Phytochemical Evaluation of Tinctures and Essential Oil Obtained from Satureja montana Herb

2020

Winter Savory (Satureja montana L.) has been used in traditional medicine and as a spice or natural food preservative in the Mediterranean region for centuries. In this paper, some technological and analytical aspects of the S. montana tinctures development and an evaluation of the essential oil composition are provided. The total phenolic and flavonoid contents and phenolic compounds profile analyzed spectrophotometrically and by high-performance thin-layer chromatography (HPTLC), respectively, were evaluated in the developed tinctures. The results showed that the tinctures prepared from the S. montana herb by maceration or remaceration are rich in polyphenols, and there is an influence of…

Teschoviruses and sapeloviruses in faecal samples from wild boar in Spain

2013

Teschovirus and Sapelovirus are two genera of the Picornaviridae family, comprising highly variable and heterogeneous enteric viruses, commonly found in faecal samples from domestic pigs. Although both of them are also known to infect wild boar, studies on their presence in these wild suids are scarce. The present study aimed at determining the presence of porcine teschovirus (PTV) and sapelovirus (PSV) in free-living wild boar populations, as well as to study their relationships with similar viruses present in pigs. Fresh faecal samples (n = 63) from wild boar were collected in Doñana Biological Reserve (SW Spain) during 2007 and 2011, and analysed using multiplex RT-PCR for the simultaneo…
