Cardiac arrest (CA) is a sudden interruption in the effective blood flow due to heart failure. The current research aimed to conduct the pathophysiological and histopathological analysis in the kidney in asphyxial cardiac arrest rat model. Cardiac arrest was induced by intravenous injection of vecuronium bromide (2 mg/kg), following stop of mechanical ventilation. Rats were kept on the CA condition for 5 minutes. After that, cardiopulmonary resuscitation (CPR) was done to achieve return of spontaneous circulation (ROSC) following intravenous injection of epinephrine bolus (0.005 mg/kg), sodium bicarbonate (1 mEq/kg) and turn on mechanical ventilation. Then Rats were sacrificed after cardiopulmonary resuscitation (CPR) following asphyxial CA at 6 hrs, 12 hrs, 1 day, 2 days, and 5 days. The intensity of renal injury measured by the serum levels of blood urea nitrogen (BUN), creatinine (Crtn). Moreover, Hematoxylin & eosin, and Periodic Acid Schiff staining in the kidney was done for evaluating the renal histopathological changes. Furthermore, COX-2 immunoreactivity and western analysis were performed in the kidney. Survival rate declined following ROSC compared to the sham group, it showed 80% at 6 hrs and decreased time-dependently to 8% at 5 days. In this study, serum BUN and Crtn levels and renal histopathological scores significantly increased after ROSC in CA. Moreover, COX-2 expression also increased after ROSC in comparison to the sham group with its peak level at 5 days following CA. Renal histological damage score and COX-2 expression were upregulated after ROSC following CA. These results direct that COX-2 takes part in the asphyxial CA-induced ischemic renal injury

The antibiotic resistance is creating a serious challenge to treat diseases especially against multidrug resistant (MDR) E. coli. The present study was conducted to evaluate the antibacterial activity of seven different flowers ethanolic extracts named as Achillea millefolium, Bombax ceiba, Chrysanthemum cinerarifolium, Hyssopus officinalis, Rosa damascena Miller, Taraxacum officinale Weber and Woodfordia fruticosa against MDR E. coli through spot test and minimum inhibitory concentrations (MIC) test. The results showed all the seven extracts have significant antibacterial activity against MDR E. coli and control. The MIC of Rosa damascena Miller, Bombax ceiba was 3.125 mg/ml and Taraxacum officinale Weber was 12.5 mg/ml for MDR E. coli. Similarly, Achillea millefolium, Hyssopus officinalis, Chrysanthemum cinerarifolium MIC value was 25 mg/ml and 12.5 mg/ml for Woodfordia fruticosa Kurtz. The current study reveals that these flowers possess strong antibacterial activity and thus can be used as potential antimicrobial agent against various resistant bacterial pathogens

The study was aimed to isolate BoHV-1 circulating in Lahore, Pakistan and its genetic characterization. For this purpose, blood samples were collected from different areas of district Lahore through convenient sampling technique. Out of 100 blood samples, 69 (69%, 95% CI: 58.86-77.66) samples have shown seropositivity against BoHV-1 through ELISA. For the isolation of BoHV-1, nasal swab samples were collected from 69 seropositive cattle and buffalo. Out of 69 nasal swab samples, only 6 samples have shown the visible cytopathic effect and confirmed through nested polymerase chain reaction by targeting glycoprotein B (gB). The phylogenetic analysis showed that local isolates showed similarity to subtype 1.1 of BoHV-1 and had 99-100% homology with Cooper strain. It was concluded that BoHV-1.1 is being circulating in Pakistan and further studies are needed which will help for clear understanding of virus characterization and development of effective local vaccine

Colistin is an important drug of last resort against lethal infections with multidrugresistant gram-negative bacteria, this antibiotic interacts on phosphate groups of lipopolysaccharides present on the outer membrane of gram-negative bacteria. This first mechanism of transferable colistin resistance involves a gene called mcr-1. Here, we described different tools such as Colistin susceptibility test, Minimal Inhibitory Concentration to find the colistin profiles of Mannheimia haemolytica and Pasteurella multocida serogroup A Moroccan strain isolated from nasal swabs and lung taken from sheep, goat and cattle with respiratory diseases during January 2015 to December 2017 in six different regions, in addition, we investigated either real time PCR to detect mcr-1 gene. Antimicrobial sensitivity test, was achieved for Fortyone isolates, the resistance rates of isolates from Pasteurellaceae species were between 59 and 71%, which respectively correspond to Mannheimia haemolytica and Pasteurella multocida segroup A. The sensitive ratios were between 29 and 41% which respectively correspond to Pasteurella multocida segroup A and Mannheimia haemolytica. Also, the MIC test was done against colistin, the results showed a resistant profile with a MIC >=64 μg/ml except for 3 strains from ruminants which have a value <2 μg/ml. The real time PCR screening test was detected with ct values ranging from 23 to 31 and confirmed the results obtained by MIC test. To our knowledge the present study is the first study which reports the resistance to colistin in Pasteurellaceae species strains isolated from ruminants in Morocco, our results suggest the necessity and the urgency for establishing a national program for monitoring antibacterial resistance against colistin

Pulmonary vascular remodeling (PVR) is the main characteristic lesion of ascites syndrome (AS) in broilers. JAZF1 plays an important role in PVR, but there is no study on its protein function and structure. In this study, the physical and chemical properties, hydrophilicity/hydrophobicity and transmembrane domain, phosphorylation site and glycosylation site, subcellular localization and signal peptide, secondary and tertiary structure, antigen peptide and conserved domain and phylogenetic relationship of JAZF1 protein were predicted online by bioinformatics tools. The results showed that the number of amino acids of JAZF1 was 243aa, the theoretical isoelectric point was 8.63, the instability index was 58.1, and the average coefficient of hydrophilicity was -0.674. It was found to be a hydrophilic protein having 35 phosphorylation sites and a N-glycosylation site with no transmembrane domain. The protein is expressed in the nucleus, there is no signal peptide distribution in the whole sequence and the secondary structure is mainly composed of random coil and α- helix. There were 7 B cell epitopes, 7 conserved domains and compared with other birds, JAZF1 is 95.61% similar. In summary, from the analysis we came to conclude that the amino acid sequence 64-80aa, 91-108aa, 136-151aa and 179-187aa can be selected as antigen sites and among which 136-151aa may be the best. This study lays a good foundation for follow-up experiments, which then provides powerful conditions for pathological detection of pulmonary vascular remodeling and gene drug therapy of ascites syndrome in broilers.

Nigella sativa and Piper nigrum are implicated in the treatment of various disorders, especially in the management of metabolic, infectious and hepatorenal ailments. However, data on the mechanism behind therapeutic potential of N. sativa and P. nigrum in liver diseases is scarce. The present study investigated the hepatoprotective potential of 70% methanolic extract of N. sativa (NSE) and P. nigrum (PNE) at varying dose levels (100 to 400 mg/kg body weight) against concanavalin A (conA)-induced liver injury. Qualitative phytochemical analysis of plant extracts was performed. Acute hepatic injury was induced by administering intraperitoneally 12mg/kg conA in Balb/c mice. The extent of hepatic injury was measured by analysing serum biochemical parameters, liver antioxidant stress assay and histopathology. Data were analysed statistically. NSE and PNE showed dosedependent hepatoprotective efficacy by lowering the conA-dependent rise in liver transaminase level. Treatment with NSE (400 mg/Kg) and PNE (400 mg/Kg) ameliorated conA-induced alterations in serum oxidative stress markers, biochemical parameters, liver function markers and histopathology. NSE indicated greater effectiveness to ameliorate the acute hepatic injury in comparison with PNE at the same dose. Collectively, pretreatment with NSE and PNE attenuated the liver injury induced by conA, might be through alleviating the antioxidant capacity of experimental mice

Tetramethyl thiuram disulfide (thiram) is an important dithiocarbamate bactericide; it has been widely used for the control of various diseases in fruits, vegetables, seeds and food grains. However, it also causes environmental pollution problems and poses a threat to human health to a certain extent. Thiram induces tibial dyschondroplasia (TD) by causing oxidative stress and antioxidants imbalance in tibial growth plate in poultry. TD is a skeletal abnormality in fastgrowing poultry birds. It has been considered an economically important disease in poultry that affects poultry industry by carcass loss at meat processing plant due to decrease in disease resistance, production performance, and carcass quality and induces breast cysts and osteomyelitis worldwide. Oxidative stress is developed due to the imbalance of free radical oxygen, which disrupts the equilibrium state of oxidant and antioxidant tending to oxidation. This review is based on the current research, mainly to explore the relationship and mechanism between tibial dyschondroplasia and oxidative stress induced by thiram, which provides a new theoretical foundation for the further research of the related mechanism.

A 3-year-old intact female Old English Bulldog and 5-month-old spayed female Chow Chow were diagnosed with entropion. Instead of surgery, hyaluronic acid (HA) filler injections were performed to correct the entropion and relieve the associated symptoms. We used the layered feathering technique, which was effective for the administration of the HA into the tissues for the correction of canine entropion. The eyelid positions were maintained for 6-8 months after the procedures. These cases demonstrate that HA filler injections relieve clinical signs quickly and effectively, though temporarily, in patients with entropion

Avian influenza subtype H9 is epizootic in backyard poultry population of Pakistan. A cross-sectional study was conducted in two districts of Pakistan from two different agro-ecological zones selected as strata to estimate H9 seroprevalence, virus prevalence and to identify risk factors associated with H9 seroprevalence in backyard poultry. A stratified two-stage cluster sampling method was applied to collect samples (n=420) from two strata (agroecological zone). A total of 210 birds were selected as elementary units from 30 clusters (7x30) in each district from each stratum. Blood and oropharyngeal swab samples were collected from each bird. Sera samples were tested by Hemagglutination Inhibition Test (HI) to detect anti-H9 antibodies and swabs samples were tested by RT-PCR for H9. Overall seroprevalence of H9 in two strata was 57.88% (95% CI 34.88-80.87%), while virus prevalence was calculated to be 3.33%. Four factors were identified to be significantly associated (P<0.05) with H9 seroprevalence in the multivariable logistic regression analysis. The odds for H9 seropositivity were 9.43 times higher in flocks with fighting cockerel compared to those having no fighting cockerel (95% CI 4.68 -18.96). Existence of any pond, canal or any other water body near home premises also enhanced likelihood of H9 seroprevalence (OR: 10.04; 95% CI 3.27- 30.83). Backyard chicken raised with other bird species (like ducks, pigeons, or captive wild birds) had higher chances of H9 seropositivity than chicken raised alone (OR 4.12, 95% CI 1.35-12.56). Visit of any farm vehicle to the village had odds ratio of 20.96 (95% CI 5.74-76.51). Future surveillance is recommended to check the level of disease throughout the country
H9亚型禽流感在巴基斯坦后院家禽种群中流行。在巴基斯坦的两个地区进行了一项横断面研究，选取了两个不同的农业生态区作为分层，以估计后院家禽中H9血清阳性率、病毒流行率并确定与H9血清阳性率相关的危险因素。采用分层两阶段整群抽样方法，从两个层(农业生态区)采集样本(n=420)。从每个地区每个地层的30个集群(7x30)中选取210只鸟作为基本单位。采集了每只鸟的血液和口咽拭子样本。采用血凝抑制试验(HI)检测血清中抗H9抗体，RT-PCR检测拭子中H9抗体。两层人群H9总体血清阳性率为57.88% (95% CI 34.88 ~ 80.87%)，病毒流行率为3.33%。多变量logistic回归分析发现4个因素与H9血清阳性率显著相关(P<0.05)。有斗鸡的鸡群H9血清阳性的几率是无斗鸡的9.43倍(95% CI 4.68 ~ 18.96)。在住家附近存在任何池塘、运河或任何其他水体也会增加H9血清阳性率的可能性(or: 10.04;95% ci 3.27- 30.83)。与其他鸟类(如鸭子、鸽子或圈养野鸟)一起饲养的后院鸡比单独饲养的鸡有更高的H9血清阳性几率(or 4.12, 95% CI 1.35-12.56)。任何农用车辆访问村庄的优势比为20.96 (95% CI 5.74-76.51)。建议今后进行监测，以检查全国的疾病水平
