A 9-month-old Belgian shepherd dog was evaluated for chronic nasal discharge. Oral examination revealed the absence of the left upper canine tooth. Radiographs showed impaction of this tooth into the left nasal cavity with caudal displacement of the tooth root. Rhinoscopy demonstrated the presence of fungal colonies. The impacted tooth was surgically removed and the nasal cavity flushed with enilconazole 1%. No recurrence was observed during a follow-up period of two years. [less ▲]

Minimum viable site networks are crucial for many threatened species but their design is always a difficult procedure. The present study investigated methods to estimate habitat quality of patches, in an ecological network for five butterfly species (Brenthis ino, Clossiana selene, Lycaena helle, Lycaena hippothoe, Proclossiana eunomia) inhabiting wet meadows. Abundance predictions were performed on the basis of botanical relevés with a multiple-species approach combining canonical correspondence analysis and multiple regression. Models are defined on a reference site set and are evaluated on a test site set. All the fitted models predicted the abundance of the butterfly species considerably well (from 61 to 86% of the variation). We evaluated the potential consequences of isolation on local populations, by comparing predicted and observed abundance. It was expected that greater differences would be observed when sites were more isolated. On the test set, differences between predicted and observed abundance were largely correlated to site isolation for L. helle and P. eunomia. The most isolated sites had greater chances to be empty, even if they had high-quality habitat. Reciprocally, when the sites were less isolated, the abundance observed was always greater than predicted, seeming to confirm the role of rescue effects. © 2003 Éditions scientifiques et médicales Elsevier SAS.

La préservation de la santé des consommateurs est devenue une préoccupation majeure en ce début de nouveau millénaire marqué par le poids de la société civile en général et des ligues de consommateurs en particulier. Les exigences en termes de qualité sanitaire et de traçabilité, qui figurent non seulement dans des réglementations toujours plus strictes mais aussi dans des référentiels de qualité ou des cahiers de charge imposés aux producteurs, traduisent la volonté des consommateurs européens de savoir où, comment et quand les aliments qu'ils ont dans leur assiette ont été produits.

Since the 1st April 2002, the European Union has extended the Transmissible Spongiform Encephalopathy testing in ruminants by including sheep and goats in the survey studies. In small ruminants, presence of the agent of Bovine Spongiform Encephalopathy was demonstrated in tonsils, so these are considered as specified risk materials. This article gives an overview of the anatomical localisation and histological structure of the tonsils in small ruminants. Anatomically, 6 different tonsils can be distinguished: 3 are located in the oropharyngeal tract (tonsilla palatina, tonsilla lingualis, tonsilla veli palatini), 2 in the nasopharyngeal tract (tonsilla pharyngea and tonsilla tubaria), and one in the laryngopharyngeal tract (tonsilla paraepiglottica). Several tonsils show a cryptic overlying epithelium (cryptic tonsil) whereas other don't (non-cryptic tonsil). Several immunological features of the tonsils are described. [less ▲]

Fully biodegradable and surface-functionalized poly(D,L-lactide) (PLA) nanoparticles have been prepared by a co-precipitation technique. Novel amphiphilic random copolyesters P(CL-co-gamma XCL) were synthesized by controlled copolymerization of epsilon-caprolactone and epsilon-caprolactone substituted in the gamma-position by a hydrophilic X group, where X is either a cationic pyridinium (gamma-Py-CL) or a non-ionic hydroxyl (gamma-OH-CL). Nanoparticles were prepared by co-precipitation of PLA with the P(CL-co-gamma-XCL) copolyester from a DMSO solution. Small amounts of cationic P(CL-co-gamma-Py-CL) copolymers are needed to quantitatively form stable nanoparticles (ca. 10 mg/100 mg PLA), although larger amounts of non-ionic P(CL-co-gamma-OH-CL) copolymers are needed (ges12.5 mg/100 mg PLA). Copolymers with a low degree of polymerization (ca. 40) are more efficient stabilizers, probably because of faster migration towards the nanoparticle-water interface. The nanoparticle diameter decreases with the polymer concentration in DMSO, e.g. from ca. 160 nm (16 mg/ml) to ca. 100 nm (2 mg/ml) for PLA/P(CL-co-gamma-Py-CL) nanoparticles. Migration of the P(CL-co-gamma-XCL) copolyesters to the nanoparticle surface was confirmed by measurement of the zeta potential, i.e. ca. +65 mV for P(CL-co-gamma-Py-CL) and -7 mV for P(CL-co-gamma-OH-CL). The polyamphiphilic copolyesters stabilize PLA nanoparticles by electrostatic or steric repulsions, depending on whether they are charged or not. They also impart functionality and reactivity to the surface, which opens up new opportunities for labelling and targeting purposes. [less ▲]

We herein report on our efforts to improve the mapping resolution of a QTL with major effect on milk yield and composition that was previously mapped to bovine chromosome 20. By using a denser chromosome 20 marker map and by exploiting linkage disequilibrium using two distinct approaches, we provide strong evidence that a chromosome segment including the gene coding for the growth hormone receptor accounts for at least part of the chromosome 20 QTL effect. By sequencing individuals with known QTL genotype, we identify an F to Y substitution in the transmembrane domain of the growth hormone receptor gene that is associated with a strong effect on milk yield and composition in the general population.

The technology of reproduction progressed considerably during the last decade, leading to a certain availability of in vitro methods for fertilisation, oocyte maturation and embryo culture. The most spectacular manipulations are cloning and transgenesis. This review focuses on the early appearance of germinal cell precursors and the long-standing fate of gametes in mammals. The evident complexity and long-term programming of events in gametes and early embryos explain part of the difficulties encountered during the development of in vitro and in vivo methods such as multiple Ovulation and embryo transfer (MOET), oestrus synchronisation, ovulation induction, superovulation, in vitro maturation and fertilisation, cryopreservation, transgenesis, nuclear transfer and cloning) and the occurrence of unexpected alterations of development, e.g. embryonic or fetal mortality, large-weight newborn syndrome and other dysregulations ill imprinting or DNA transmission.
