Diagnosis of gastrointestinal parasites in reptiles: comparison of two coprological methods
Exotic reptiles have become increasingly common domestic pets worldwide and are well known to be carriers of different parasites including some with zoonotic potential. The need of accurate diagnosis of gastrointestinal endoparasite infections in domestic reptiles is therefore essential, not only for the well-being of captive reptiles but also for the owners. Here, two different approaches for ...


Nodules from Fynbos legume Virgilia divaricata have high functional plasticity under variable P supply levels
Legumes have the unique ability to fix atmospheric nitrogen (N2) via symbiotic bacteria in their nodules but depend heavily on phosphorus (P), which affects nodulation, and the carbon costs and energy costs of N2 fixation. Consequently, legumes growing in nutrient-poor ecosystems (e.g. sandstone derived soils) have to enhance P recycling and/or acquisition in order to maintain N2 fixation. In t...
A proteomic approach to Physcomitrella patens rhizoid exudates
The interaction between plants and the surrounding environment has been widely studied, specially the defence reactions and the plant-plant interactions. One of the most remarkable metabolic features of plant roots is the ability to secrete a vast array of compounds into the rhizosphere, not only of low molecular weight but also polysaccharides and proteins. Here, we took advantage of proteomic...


Comparative analysis of zygospore transcripts during early germination in Chlamydomonas reinhardtii
The unicellular green alga Chlamydomonas reinhardtii has a haplontic life cycle, and forms diploid zygotes for reproduction. The zygospore, a sporulating zygote, begins germination in response to light signals, generating haploid progenies and inducing several cell-biological events; e.g., DNA synthesis and meiotic division, successively. Their regulatory mechanisms remain largely unknown, so w...
Biological Activities of Origanum, Satureja, Thymbra and Thymus Species Grown in Turkey
In the present study, seven thyme species Origanum onites, O. vulgare var. hirtum, O. vulgare var. gracile, O. syriacum, Satureja hortensis, Thymbra spicata, and Thymus vulgaris were used. The essential oils of these plants were obtained by the hydrodistillation method. Antimicrobial activities of the essential oils against microorganisms, including multiple antibiotic-resistant bacteria, were ...


Chemical Composition and Biological Activity of Haplophyllum tuberculatum Juss. Essential Oil
The essential oil of Haplophyllum tuberculatumwas prepared by hydrodistillation of the fresh flowering aerial parts of the plant collected from Saudi Arabia. The oil was subsequently analyzed by GC and GC-MS. Thirty seven compounds, accounting for 96.4 % of the oil composition were identified. The major components were trans-p-menth-2-en-1-ol (19.2 %), cis-p-menth-2-en-1-ol (13.2 %), myrcene (1...
Comparison of computed tomographic and pathologic findings in 17 dogs with primary adrenal neoplasia
The CT appearance of canine adrenal masses has been reported, but associations between imaging features and pathologic features of these lesions have not been investigated in detail. The purpose of this study was to test associations between different types of adrenal neoplasia and their CT and pathologic features. A retrospective cross-sectional study was performed and inclusion criteria were ...

Prevalence and characterization of small tympanic bone spicules and drumstick-like hyperostotic tympanic bone spicules in the middle ear cavity of dogs
Rounded, sessile, hyperattenuating structures detected in computed tomography (CT) studies of canine tympanic bullae have been termed “otoliths.” These have been proposed to represent dystrophic mineralizations or heterotopic bone formations in the middle ear that are potentially related to chronic otitis media. of the current study were to describe the prevalence, macroscopic, and histolog...
Imaging diagnosis—urinary bladder duplication in a cat
A female kitten presented for chronic, intermittent, antibiotic-responsive urinary incontinence and chronic kidney disease. Abdominal ultrasound identified bilateral pelvic/ureteral dilation and three closely apposed thin-walled fluid-filled structures in the caudal abdomen, extending toward the pelvic inlet. Excretory urography and negative contrast cystography identified contrast medium accum...

Initial influence of right versus left lateral recumbency on the radiographic finding of duodenal gas on subsequent survey ventrodorsal projections of the canine abdomen
Identification of the duodenum and potential abnormalities on survey abdominal radiographs is often difficult unless it contains gas. This study investigated the effect of patient positioning on the presence of duodenal gas in survey abdominal radiographs. One hundred dogs receiving a three-view survey abdominal radiographic study were enrolled in a prospective, randomized study where all dogs ...
Changes in silica in litterfall and available silica in the soil of forests invaded by bamboo species (Phyllostachys pubescens and P. bambusoides) in western Japan
In Japan, the total area covered by bamboo species has been increasing in recent years. A limited number of studies have been conducted to elucidate the changes in nutrient dynamics in forests invaded by bamboo species. Bamboo species are silica accumulators, taking up silica actively from the soil and accumulating most of the absorbed silica in the leaves. Therefore, it could be assumed that b...

New and unusual forms of calcium oxalate raphide crystals in the plant kingdom
Calcium oxalate crystals in higher plants occur in five major forms namely raphides, styloids, prisms, druses and crystal sand. The form, shape and occurrence of calcium oxalate crystals in plants are species- and tissue-specific, hence the presence or absence of a particular type of crystal can be used as a taxonomic character. So far, four different types of needle-like raphide crystals have ...
Selective induction of putative iron transporters, OPT8a and OPT8b, in maize by mycorrhizal colonization
Arbuscular mycorrhizas support nutrient uptake from the soil. Here we demonstrated Iron-59 (59Fe) uptake in maize (Zea mays L.) through the mycorrhizal roots. Arbuscular mycorrhizal colonization did not strongly induce Strategy II-related genes, but the putative iron transporter genes, OPT8a and OPT8b, were induced by more than 50-fold. Our data provide a previously undescribed gene expressi...
Essential Oil of Solanum juglandifolium Humb. & Bonpl. ex Dunal Leaves from Colombia
The essential oil from leaves of Solanum juglandifolium Humb. & Bonpl. ex Dunal grown in Colombia was analyzed by GC and GC-MS. Ninety-four compounds were identified, of which the most prominent were the sesquiterpenes germacrene-D-4-ol (26.6 %), α-cadinol (21.7 %), junenol (13.4 %), and δ-cadinene (11.7 %).
Chemical Composition Antioxidant and Antimicrobial Activities of the Essential Oils of Matricaria aurea Loefl. Growing in Tunisia
The present study describes the chemical composition, antibacterial, antifungal and antioxidant activities of essential oils isolated by steam distillation from the aerial parts and roots of the Tunisian Matricaria aurea Loefl. The chemical composition of essential oils was analyzed by gas chromatography/mass spectrometry (GC-MS). 105 components were identified, of which 1,5 bis (dicyclohexylph...
