Asthma is prevalent in children and cats, and needs means of noninvasive diagnosis. We sought to distinguish noninvasively the differences in 53 cats before and soon after induction of allergic asthma, using NMR spectra of exhaled breath condensate (EBC). Statistical pattern recognition was improved considerably by preprocessing the spectra with probabilistic quotient normalization and glog transformation. Classification of the 106 preprocessed spectra by principal component analysis and partial least squares with discriminant analysis (PLS-DA) appears to be impaired by variances unrelated to eosinophilic asthma...

The trematodes belonging to the genus Platynosomum are biliary parasites of birds and mammals (domestic and wildlife) in tropical and subtropical areas of the globe. Despite several reports on platynosomosis in captive nonhuman primates, mainly in South America, the taxonomy of species of Platynosomum that infect these hosts remains confused, and it is not clear whether the species found in cats is the same that infects nonhuman primates. Because a detailed morphological study of Platynosomum from nonhuman primates is lacking, in this study we analyzed specimens of Platynosomum recovered from the biliary system of Callithrix penicillata kept in captivity in an animal facility...

Despite their medical and veterinary importance, some tick species are so poorly studied, that their role within pathogen vector transmission cycles is difficult to assess. The tick Ixodes ventalloi is one such species, and its biology and phylogenetic status remain an issue of debate. In the present study, specimens of adult I. ventalloi (n = 65 females; n = 31 males) infesting cats in the Lipari Island (Aeolian archipelago, Sicily, southern Italy) were characterized morphologically and molecularly, the latter based on mitochondrial 16S rRNA and cytochrome c oxidase subunit 1 (cox1) genes...

Naphthoquinones are secondary metabolites widely distributed in nature and produced by bacteria, fungi and higher plants. Their biological activity may result from induction of oxidative stress, caused by redox cycling, or direct interaction with cellular macromolecules, in which quinones act as electrophiles. The redox homeostasis is known as one of factors involved in auxin-mediated plant growth regulation. To date, however, little is known about the crosstalk between reactive oxygen species (ROS) produced by quinones and the plant growth hormone auxin (IAA)...

Artificial light at night (ALAN), termed light pollution, is an increasingly important anthropogenic environmental pressure on wildlife. Exposure to unnatural lighting environments may have profound effects on animal physiology, particularly during early life. Here, we experimentally investigated for the first time the impact of ALAN on body mass and oxidative status during development, using nestlings of a free-living songbird, the great tit (Parus major), an important model species. Body mass and blood oxidative status were determined at baseline (=13 days after hatching) and again after a two night exposure to ALAN...

Tramadol is widely used to manage mild to moderately painful conditions in dogs. However, this use is controversial since clinical efficacy studies in dogs showed conflicting results, while pharmacokinetic studies demonstrated relatively low circulating concentrations of O-desmethyltramadol (M1). Analgesia has been attributed to the opioid effects of M1, while tramadol and the other major metabolite (N-desmethyltramadol, M2) are considered inactive at opioid receptors. The aims of this study were to determine whether cytochrome P450 (CYP) dependent M1 formation by dog liver microsomes is slower compared with cat and human liver microsomes; and identify the CYPs responsible for M1 and M2 formation in canine liver...

During the last decade, analysis of anti-Müllerian hormone (AMH), highly conserved between mammalian species, has contributed to new information in reproductive endocrinology, due to clinically available diagnostic assays. AMH is produced solely in the gonads, in the Sertoli cells of testes and granulosa cells of the ovary, and thus offers possibilities to diagnose physiologic and pathologic conditions involving these organs. This article reviews indications for AMH analysis in cats and dogs, including diagnosing the presence of gonads, and granulosa or Sertoli cell tumours...

Ovarian tissue cryopreservation followed by tissue culture is a promising approach to preserving the fertility of biomedical models and endangered species. The objective of this study was to investigate the impact of exposure time to vitrification solution and presence of sucrose using different exposure temperatures and base media on intra-ovarian follicle integrity. Peripubertal ovarian cortical pieces were obtained by isolating the cortex and dissecting it into 1 × 1 × 0.2 mm(3) pieces. The cortical pieces were then exposed to equilibration solution and then vitrification solutions (VS) in one of the conditions mentioned above, plunged directly into liquid nitrogen and stored for ≥24 hr in liquid nitrogen...

Caliciviruses are contagious pathogens of humans and various animals. They are the most common cause of viral gastroenteritis in humans, and can cause lethal diseases in domestic animals such as cats, rabbits and immunocompromised mice. In this study, we conducted cytopathic effect-based screening of 2080 selected compounds from our in-house library to find antiviral compounds against three culturable caliciviruses: feline calicivirus, murine norovirus (MNV) and porcine sapovirus (PoSaV). We identified active six compounds, of which two compounds, both related to theaflavins, showed broad antiviral activities against all three caliciviruses; three compounds (abamectin, a mixture of avermectin B1a and B1b; avermectin B1a; and (-)-epigallocatechin gallate hydrate) were effective against PoSaV only; and a heterocyclic carboxamide derivative (BFTC) specifically inhibited MNV infectivity in cell cultures...

Ethanol abuse is a serious public health problem that is associated with several stages of alcoholic liver disease (ALD) and a high incidence of morbidity and mortality. Alcoholic fatty liver disease (AFLD), the earliest stage of ALD, is a multifactorial injury that involves oxidative stress and disruptions of lipid metabolism. Although benign and reversible, no pharmacological treatments are available for this condition. In the present study, we induced AFLD in mice with 10% ethanol and a low-protein diet and then orally treated them with a hydroethanolic extract of Baccharis trimera (HEBT; 30 mg kg(-1))...

To clarify the interaction between different antioxidant enzymes for monitoring oxidative stress and ROS burst in rice senescent leaves, we investigated the genotype-dependent alteration in temporal patterns of the O2(•-) production rate, H2O2 content, and ROS-scavenging enzyme activities during leaf senescence in two rice genotypes, namely, the premature senescence of flag leaf (psf) mutant and its wild type. Results showed that the psf mutant differed obviously from its wild type in leaf O2(•-) generation rate and H2O2 content accumulation, and the decreased activities of SOD, CAT, and APX in the psf leaves were strongly responsible for the increased ROS level and the accelerated leaf senescence...
