Dual-energy computed tomography of canine uroliths
2017
Nykamp, Stephanie G.
OBJECTIVE To determine whether dual-energy CT (DECT) could accurately differentiate the composition of common canine uroliths in a phantom model. SAMPLE 30 canine uroliths with pure compositions. PROCEDURES Each urolith was composed of ≥ 70% struvite (n = 10), urate (8), cystine (5), calcium oxalate (4), or brushite (3) as determined by standard laboratory methods performed at the Canadian Veterinary Urolith Centre. Uroliths were suspended in an agar phantom, and DECT was performed at low (80 kV) and high (140 kV) energies. The ability of low- and high-energy CT numbers, DECT number, and DECT ratio to distinguish uroliths on the basis of composition was assessed with multivariate ANOVA. RESULTS No single DECT measure differentiated all urolith types. The DECT ratio differentiated urate uroliths from all other types of uroliths. The DECT and low-energy CT numbers were able to differentiate between 8 and 7 pairs of urolith types, respectively. CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that DECT was unable to differentiate common types of canine uroliths in an in vitro model; therefore, it is unlikely to be clinically useful for determining urolith composition in vivo. Given that the primary reasons for determining urolith composition in vivo are to predict response to shock wave lithotripsy and develop a treatment plan, future research should focus on the correlation between DECT measurements and urolith fragility rather than urolith composition.

OBJECTIVE To investigate protein kinase CK2 (CK2) expression in squamous cell carcinoma (SCC) of cats and to examine effects of CK2 downregulation on in vitro apoptosis and viability in SCC. SAMPLE Biopsy specimens of oral mucosa and testis and blood samples from clinically normal cats, biopsy specimens of oral SCC from cats, and feline SCC (SCCF1) and mammary gland carcinoma (K12) cell lines. PROCEDURES Immunohistochemically labeling for CK2α was performed on biopsy specimens. Sequences of the CK2α subunit gene and CK2α’ subunit gene in feline blood and feline cancer cell lines were determined by use of PCR and reverse-transcription PCR assays followed by direct Sanger sequencing. Specific small interfering RNAs (siRNAs) were developed for feline CK2α and CK2α'. The SCCF1 cells were treated with siRNA and assessed 72 hours later for CK2α and CK2α’ expression and markers of apoptosis (via western blot analysis) and for viability (via 3-[4,5-dimethylthiazol-2-yl]-5-[3-carboxymethoxyphenyl]-2-[4-sulfophenyl]-2H-tetrazolium assays). RESULTS CK2α was expressed in all feline oral mucosa samples and 7 of 8 oral SCC samples. Expression of CK2α and CK2α’ was successfully downregulated in SCCF1 cells by use of siRNAs, which resulted in decreased viability and induction of apoptosis. CONCLUSIONS AND CLINICAL RELEVANCE In this study, CK2 appeared to be a promising therapeutic target for SCCs of cats. A possible treatment strategy for SCCs of cats would be RNA interference that targets CK2.

Gani, M. U. | Siddiqui, M. S. I. | Islam, K. | Ahmed, S. | Rashid, M. H. | Moonmoon, S. | Mostofa, M.
The study of alterations of some hematological parameters in a experimentally induced lead toxicosis were carried out on a total of 15 (15 days old) male weaning Long- Evans (ICDDRB strain) rats. The rats were randomly divided in to three equal groups, each consisting of fiverats. Rats of group A were kept as control (without giving any treatment), group B received lead acetate alone @ 6 mg/ml drinking water and group C receivedlead acetate @ 6 mg/ml plus whole milk (Star ship®) 150 mg/ml drinking water. The result showed a most significantly (p< 0.01) decreased TEC, TLC and Hb%observed on day 56 in group B but in group C, these counts decreased significantly (p< 0.05) on days 56 of experiment. From the study, it was concluded that treatment with lead acetate at low doses has harmfuleffects on experimental animals including hematological alterations.

A cross-sectional study was designed to determine the level ofawareness of selected dairy farmers to herd health program (HHP) and compliance in the Program LadangAngkat (PLA). The study also determined the association between farmers’ awareness and compliance in promoting herd health. An open-ended questionnaire was randomlyadministered to five dairy cattle farms within Selangor and Negeri Sembilan as representative dairy farms enlisted into the PLA of Faculty of Veterinary Medicine, Universiti Putra Malaysia. The mean herd size of the farms was 102.20±20.80, with a range of 30-160 heads of dairy cattle, having an average mean number of milking cows at 29.40±11.22. There was a higher (p<0.05) mean herd health awareness level (72.86±5.78%) among the farmers once compared with the mean compliance level (61.2 ± 4.1%) for 10 out of the 14 HHP components; with the lowest compliances being disease monitoring programme(33.20%) and biosecurity (39.9%). There was a significant (p<0.05), direct, weak positive correlation (r = 0.245; p = 0.042) between farmers’ awareness and farmers’ compliance to the 14 components of the HHP. This study highlights an appreciable level of awareness among dairy farmers in the PLA, with a relatively low compliancelevels to the HHP components.

A comprehensive study was conducted on the clinical observationsincluding clinical history, physical examination along with haematobiochemical alteration on 41 naturally occurring cases of canine babesiosis from Punjab state, India. Examination of 964 dogs revealed 4.25 percent (41/964) prevalence of the disease including 3.84 percent (37) B. gibsoni and 0.41 percent (4) B. canis infected cases. Clinical and parasitological diagnosis was finally confirmed by polymerase chain reaction. A large variation of clinical anifestations including rare findings of paraplegia, blindness, ocular bleeding, immune mediated haemolytic anaemia (IMHA), ascites and skin lesions were observed among the affected animals. Bloodfilms showed anisocytosis and nucleated erythrocytes indicating regenerative anaemia. Blood parameters of the affected dogs revealed significant decrease in Hb, TEC, PCV and thrombocytes. Significantdecrease in lymphocytes was found in B. gibsoni affected animals. The affected dogs showed significant increase in serum bilirubin, ALT, AKP, BUN and creatinine. Haemato-biochemical observations wereindicative of severity of babesiosis in dogs.

This paper presents the resultsof an experimental attempt to improve thedrying kinetics for the retention of colourand sialic acid in edible bird’s nest throughheat pump drying. Kinetics of hot air dryingand heat pump drying were studied byperforming various drying trials on ediblebird’s nest. Isothermal drying trials wereconducted in hot air drying and heat pumpdrying at a temperature range of 40 °C-90 °C and 28.6 °C-40.6 °C, respectively.Intermittent drying trials were carried outin heat pump drying with two differentmodes, which are periodic air flow supplyand step-up air temperature. Experimentalresults showed that heat pump drying withlow temperature dehumidified air not onlyenhanced the drying kinetics but alsoproduced a stable final product of ediblebird’s nest. Heat pump-dried edible bird’ssamples retained a high concentration ofsialic acid when an appropriate dryingmode was selected.

A survey of 95 wild rats which were captured from various locations was conducted to determine the diversity and distribution of ectoparasites and endoparasites infesting wild rat population around the city of Ipoh and Kuala Lumpur. The rodents captured were Rat tus norvegicus and post mortem was carried out immediately after capture, with skin and organs examined for parasite infection. Ectoparasites recovered were blood sucking louse (Polyplax spinulosa) and mites (Myocoptes musculinus). Endoparasites recovered were nematodes (Aspiculuris tetraptera, Trichuris sp., and two strongyles, one of which is Strongyloides sp.) And three intestinal protozoan parasites (Blastocystis sp., Trichomonas sp., and a coccidia). Low diversity of ecto- and endoparasites were observed infecting wild rat population caught in Ipoh as compared to Kuala Lumpur.
