Toxoplasma gondii, an obligate intracellular parasite, is the aetiological agent of toxoplasmosis, a disease that affects approximately 25% – 30% of the world’s population. At present, no safe and effective vaccine exists for the prevention of toxoplasmosis. Current treatment options for toxoplasmosis are active only against tachyzoites and may also cause bone marrow toxicity. To contribute to the global search for novel agents for the treatment of toxoplasmosis, we herein report the in vitro activities of previously synthesised benzyltriazole derivatives. The effects of these compounds against T. gondii in vitro were evaluated by using a expressing green fluorescent protein (GFP) type I strain parasite (RH-GFP) and a type II cyst-forming strain of parasite (PruΔku80Δhxgprt). The frontline antitubercular drug isoniazid, designated as Frans J. Smit -isoniazid (FJS-INH), was also included in the screening as a preliminary test in view of future repurposing of this agent. Of the compounds screened, FJS-302, FJS-303, FJS-403 and FJS-INH demonstrated 80% parasite growth inhibition with IC50 values of 5.6 µg/mL, 6.8 µg/µL, 7.0 µg/mL and 19.8 µg/mL, respectively. FJS-302, FJS-303 and FJS-403 inhibited parasite invasion and replication, whereas, sulphadiazine (SFZ), the positive control, was only effective against parasite replication. In addition, SFZ induced bradyzoite differentiation in vitro, whilst FJS-302, FJS-303 and FJS-403 did not increase the bradyzoite number. These results indicate that FJS-302, FJS-303 and FJS-403 have the potential to act as a viable source of antiparasitic therapeutic agents.

The cross-pin technique for the treatment of distal femoral physis fractures (specifically, Salter-Harris Type I fractures) was investigated using femurs collected from beagle cadavers. The pin was inserted from the medial surface of the femur at an inclination of approximately 30 to 45° relative to the long axis of the femur in the anteroposterior direction; the pin exit was set proximal to the origin of the long digital extensor tendon. Digital and radiographic images of the femur in the anteroposterior and lateral directions were obtained. In both types of images, the insertion angle of the pin relative to the long axis was measured. Results suggest that when inserting a pin proximal to the fracture line, the ideal position can be achieved by inclining the pin approximately 20° cranially relative to the long axis of the lateral direction of the femur, in addition to the previously described criteria.

It was aimed to investigate the effects of ketamine combination administered with xylazine used for general anesthesia in dogs on arterial blood pressure, heart rate, and body temperature. Materials and Methods: In the study, a total of 20 dogs, 14 females and 6 males, from various breeds and ages 1 to 5, which undergone elective ovariohysterectomy or castration according to body weights. 1 mg/kg xylazine (xylazine hydrochloride, 23.3mg/ml, Xylazinbio 2% Bioveta®, Czechia) and 10 mg/kg ketamine (ketamine hydrochloride, 100 mg/ml, Ketasol 10% Richter® Pharma Ag, Austria) combination within a single injection with 21G needle were applied intramuscularly. The food and water access were ceased 12 hours before drug administration. Systolic and diastolic blood pressures, pulse measurements, and body temperatures were measured 3 times before and 5 times during anesthesia (at the 15th, 30th, 45th, 60th and 120th minutes of anesthesia) by using the AM6100 veterinary bedside monitor. Muff was placed to cover 1/3 of the proximal leg and for the artery to be recognizable by the microprocessor. Pulse rates were measured with electrodes connected to the device. Body temperature was measured by a rectal thermometer which was a part of the device. Measurements were taken before anesthesia was considered as control measurements.In systolic blood pressure, the recordings at 0, 15th, 30th mins have been found as statistically significant in relation to 45th, 60th, and 120th (p<0.05). In diastolic blood pressure, there were no significant differences recorded. The change between the preintervention and post-application has been found significant (p<0.001). Body temperature has shown a meaningful change in comparison to the starting point after the readings (p<0.001).Eventually, decreases in blood pressure, heartbeat, and body temperature were observed for the dogs that have been anesthetized with the combination of xylazine-ketamine.

This study was conducted with the purpose of investigating the distribution of the Activating Transcription Factor 6 (ATF6) and the Nerve Growth Factor (NGF) in the duodenum tissue of diabetic and non-diabetic rats. Eighteen female Sprague dawley rats were randomly divided into three groups as thecontrol, sham and diabetes groups. Routine histological and immunohistochemical methods were appliedon the duodenum tissues collected at the end of the study.Results: It was determined that the villus length measurements showed a statistically significant differencebetween the control and diabetes groups. There was NGF immunoreactivity which was moderate anddiffuse cytoplasmic in the villus intestinalis and muscularis layer in all groups, weak in the crypts andglands in the control and sham groups and moderate and diffuse cytoplasmic in the diabetes group. ATF6immunoreactivity was determined moderate in the villus intestinalis, crypts, glands and muscularis layerin the control and sham groups and strong diffuse cytoplasmic in the diabetes group. It wasdetermined that both NGF and ATF6 immunoreactivity increased in the duodenum tissue of the rats onwhich diabetes was induced experimentally.

This study; It was aimed to compare serum and rumen content, trace element and serum vitamin levels and rumen content in indigestion cattle with healthy animals. Materials and Methods: The study was conducted on a total of 30 cattle, 10 healthy (control group) and 20 indigestion group. Indigestion diagnosis in animals was determined by anamnesis information, clinical and rumen content examination.Hematologically, there was no statistical difference between indigestion and control groups. Serum magnesium (Mg), calcium (Ca), zinc (Zn) levels of the measured trace elements decreased in the group with indigestion (p<0.05), while the levels of cobalt (Co) increased significantly (p<0.01). While there was a significant increase (p<0.5) in cattle with indigestion in rumen content Ca values compared to healthy cattle, serum levels were decreased (p<0.05). A positive correlation (p<0.01) was determined between rumen content levels of indigestion cattle and serum Mg levels of control group and rumen content of control group. In addition, a negative correlation was found between serum Ca and rumen content values of cattle with indigestion. In serum vitamin levels, Vitamin B1 (Vit B1) decreased statistically (p<0.05), while Vitamin B12 (Vit B12) was found to increase non-statistically (p>0.05).As a result, it was concluded that the decrease in serum Mg, Ca and Zn values in indigestion animals is important and these trace elements should be used in treatment.

Indiscriminate use of antibiotics in poultry farms increases the chance of antibiotic resistant and extended-spectrum β-lactamase (ESBL) producing bacteria in Bangladesh. Therefore, the study was under taken to detect ESBL producing Escherichia coli (E. coli) in chickens. Materials and methods: A total of 60 cloacal swab samples (20 from commercial layer, 20 from commercial broiler and 20 from commercial sonali chickens) were collected from Rajshahi district of Bangladesh. The E. coli was isolated from these samples and identified based on cultural, staining, and biochemical characteristics. The disk diffusion method was used to assay the antibiotic resistant/sensitivity patterns of the isolated E. coli. Phenotypc detection of ESBL producing E. coli was also done.The prevalence of E. coli in chickens was 61.67% in Rajshahi district of Bangladesh, where the prevalence was 60%, 60%, and 65% in commercial layer, commercial broiler, and commercial sonali chickens, respectively. The antibiotic sensitivity assay of E. coli isolated from commercial layer chickens showed 100%, 80%, 50%, 40%, and 40% resistant to amoxicillin, tetracycline, cefotaxime, ciprofloxacin, and ceftazidime, respectively. E. coli isolated from commercial broiler chickens showed 100%, 100%, 60%, 50%, and 40% resistant to amoxicillin, tetracycline, cefotaxime, ceftazidime, and ciprofloxacin, respectively. E. coli isolated from commercial sonali chickens showed 90%, 70%, 50%, 50%, and 40% resistant to amoxicillin, tetracycline, cefotaxime, ciprofloxacin, and ceftazidime, respectively. In phenotypic detection, the overall prevalence of ESBL producing E. coli was 43.33%, where 40%, 50%, and 40% in the commercial layer, commercial broiler, and commercial sonali chickens, respectively in Rajshahi district of Bangladesh.These results indicated that chickens are a potential reservoir for ESBL producing E. coli and their antibiotic resistances are obviously significant. These findings will help us to make proper guideline for the treatment, prevention and control of E. coli prevalent in chickens in Bangladesh.

The present study was carried out to investigate the possibility of using different levels of bee pollen and apigenin extract in beef meatballs to evaluate shelf-life, nutritional and quality properties of beef meatballs under different storage conditions. It was determined, using the HPLC method, that bee pollen contains a high level of apigenin under optimal conditions. Bee pollen and apigenin were added to meatballs at different concentrations in five groups. Meatballs were made with control, 1-2% bee pollens/apigenin. Quality and safety evaluation of meatballs were determined by sensory, physicochemical, biochemical and microbiological tests. The analyses were conducted at 1st, 3rd, 7th and 14th days of interval. A statistically significant decrease was found in FFA, POV and TBARS levels of meatballs on different days of storage (p<0.05). When compared to the control group, the bioactive compounds preserved the microbiological and chemical properties of meatballs during frozen storage (14 days).It was concluded that the extracts with 2% bee pollen concentrations can be used as biopreservative agents for meat and meat products.

The aim of the current study was to evaluate the effect of different levels of Curcuma longa on some physiological and biochemical parameters, as well as some egg productive and quality characters and the intestinal microflora of local quail. 240 one-day-old quail were distributed randomly into 4 groups (60 birds/group) with 3 replicates. The groups were as follows: 1st group (control) birds were reared on standard ration, the 2nd, 3rd and 4th groups birds were reared on standard ration supplemented with 3, 6 and 9 gm turmeric/kg ration respectively. The results revealed that the turmeric improve blood picture as represented by the significant increase of RBCs, Hb and PCV% specially in 3rd and 4th treatments. Also, the turmeric reduced significantly triglycerides and cholesterol compared with the control. Curcuma longa treatment improved the intestinal microflora represented by the significant decrease in the number of pathogenic flora (Salmonella and E. coli), and significant increase in the benefit flora (Lactobacillus). On the other hands treatments reduced significantly the age of 1st egg production and enhance the age of 50% egg production. In conclusion, Curcuma longa treatment induced ameliorative effects on some of physiological and productive performance of quail.
