Cytokines Expression and Nitric Oxide Production under Induced Infection to Salmonella Typhimurium in Chicken Lines Divergently Selected for Cutaneous Hypersensitivity. ASIAN-AUSTRALASIAN JOURNAL OF ANIMAL SCIENCES 2014; 25:1038-44.

Abstract
In the present study, the impact of Salmonella Typhimurium on cell-mediated immunity (CMI) was investigated in 5 week-old immuno divergent broiler lines selected for the high and low response to phytohemagglutinin-P. The immune response was assessed in peripheral-blood mononuclear cells (PBMCs) induced with Salmonella Typhimurium at different time intervals (0 h, 0.5 h, 2 h, 4 h, 6 h, 12 h and 24 h). The differential mRNA expression patterns of IFN-γ, IL-2 and iNOS were evaluated by quantitative real time PCR. In-vitro production of nitric oxide (NO) was also estimated in the culture supernatant and correlated with iNOS mRNA expression. Present study showed higher production of NO in the high cell-mediated line (HCMI) as compared to the low cell-mediated line (LCMI) upon stimulation with Salmonella Typhimurium. Correspondingly, higher mRNA expression of iNOS and IFN-γ were observed in high response birds (HCMI); but IL-2 was down regulated in this line compared to the low response birds (LCMI). Significantly (p<0.05) higher expression of iNOS, IFN-γ and higher production of NO in high line indicated that the selection for PHA-P response might be employed for increasing the immune competence against Salmonella Typhimurium in chicken flocks.

In vitro rapid clearance of infectious bursal disease virus in peripheral blood mononuclear cells of chicken lines divergent for antibody response might be related to the enhanced expression of proinflammatory cytokines. Res Vet Sci 2013; 95:957-64. [PMID: 24075224 PMCID: PMC7111768 DOI: 10.1016/j.rvsc.2013.08.018] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2012] [Revised: 07/09/2013] [Accepted: 08/24/2013] [Indexed: 11/21/2022]
Abstract
Infectious bursal disease (IBD) is an acute and highly contagious viral disease of young chickens caused by infectious bursal disease virus (IBDV). An effective way to control IBDV would be to breed chickens with a reduced susceptibility to IBDV infection. In the present work, we used chickens selected for high and low specific responses to sheep red blood cells (SRBC) (H and L, respectively) to assess the susceptibility of differential immune competent animals to IBDV infection. The peripheral blood mononuclear cells (PBMCs) of high SRBC line (HL) and low SRBC line (LL) were infected with IBDV and viral RNA loads were determined at different time post-IBDV infection. Chicken orthologues of the T helper 1 (Th1) cytokines, interferon-γ (IFN-γ) and interleukin-2 (IL-2); a Th2 cytokine, IL-10; a pro inflammatory cytokine, IL-6; the CCL chemokines, chCCLi2, chCCLi4 and chCCLi7; colony stimulating factor, GM-CSF; and a anti-inflammatory cytokine, transforming growth factor β-2 (TGFβ-2) were quantified. The expression of chCCLi2, chCCLi4 and chCCLi7 was significantly higher in L line as compared to H line. However, in H line the viral RNA loads were significantly lower than in L line. Therefore, the upregulated chemokines might be associated with the susceptibility to IBDV. The expression of IFN-γ, IL-2 and IL-6 was significantly higher in H line as compared to L line. We assume that the higher proinflammatory cytokines expression in H line might be related to the rapid clearance of virus from PBMCs. Significantly higher levels of IL-10 and TGFβ-2 mRNAs in L line might be related to the pathogenesis of IBDV. In conclusion, selection for antibody responses appears to influence the expression profiles of chemokines and cytokines against IBDV. Further, the selection for high SRBC response might improve the immuno-competence of chickens against IBDV.

Abstract
The benefits of minimally invasive surgery have led to adoption of laparoscopic assisted robotic surgery across several surgical specialties. Surgeons have acquired considerable expertise in conventional laparoscopic surgery but robotic assistance has allowed performance of similar tasks with greater ease. However, the embracing of minimal invasive surgical techniques demands the rapid acquisition of new skills by surgical trainees and practising surgeons.

Abstract
Abstract
The seismic design of a nuclear power plant includes two levels of design earthquake, the safe shutdown earthquake (SSE) and the operating basis earthquake (OBE). The OBE and SSE are considered in the nuclear power plant design as required by the IAEA safety regulations. A typical piping model for the ETRR-2 core cooling system includes ASME-class 1, 2 and 3 piping and was analyzed with regard to both IAEA safety regimes. A load combination, as stated by the IAEA Safety Guide 50-SG-S2, has been considered. The safety guide requires that the OBE should equal to at least one half SSE and that the plant should be shut down if exposed to earthquake intensity greater than the OBE. The results reflect the requirement for the precise design of a supporting system to accommodate for higher seismic peaks more than 0.2 g and the system needs to be more flexible.

Abstract
Biodegradation of two B-trichothecenes nivalenol (NIV) and deoxynivalenol (DON) have been studied in a RUSITEC (rumen simulation technique) system. The fermentation studies were carried out in vessels containing the rumen fluid. To reach steady state an adaptation period of one week was carried out. The mycotoxin standards were then added into the fermentor in a concentration of 1ppm NIV and 2ppm DON. The kinetics of NIV and DON biodegradability during the fermentation process were monitored by using a rapid HPLC method combined with a mass spectrometer and an atmospheric pressure chemical ionisation (APCI(-)) interface. Also the effect of mycotoxin addition on different parameters such as ammonia production, pH, gas production and volatile fatty acids have been studied.

Abstract
Abstract
The safety evaluation of the primary core cooling system requires an accurate hydraulic analysis of the system during normal and abnormal conditions. A model of the piping components of a common research reactor system is obtained and illustrated using the FE/PIPE Finite Element Package. Different accidents leading to a loss of the system function are investigated, such as pipe rupture and valve failure. The hydraulic-structure interaction and dynamic parameters responded to the accident are obtained during the transient time. The scenario time domain is selected to be very short (2.0 s) to get more conservative calculations and more safety margins in the final design. The results reflect that the natural system frequency should be in the margin greater than 34 Hz otherwise resonance with the generated forces during the accident will happen, that could lead to a system failure.

Abstract
Protein kinase CK2 participates in a wide range of cellular events, including the regulation of cellular morphology and migration, and may be an important mediator of angiogenesis. We previously showed that in the retina, CK2 immunolocalizes mostly to vascular endothelium and astrocytes in association with the cytoskeleton. Additionally, CK2 inhibitors significantly reduced retinal neovascularization and stem cell recruitment in the mouse model of oxygen-induced proliferative retinopathy. We have also shown that CK2 and F-actin co-localized in actin stress fibers in microvascular endothelial cells, and that highly specific CK2 inhibitors caused cell rounding in astrocytes and microvascular endothelial cells, which was alleviated by serum that promotes spreading by Rho/Rho-kinase (RhoK) activation of myosin II. Therefore, we examined a possible role of CK2 in the regulation of actin-myosin II-based contractility. Treatment with CK2 inhibitors correlated with disassembly of actomyosin stress fibers and cell shape changes, including cytoplasmic retraction and process formation that were similar to those occurring during astrocyte stellation. Low doses of specific inhibitors of kinases (RhoK and MLCK) that phosphorylate myosin light chain (MLC) enhanced the effect of suboptimal CK2 inhibition on cell shape. Such striking stellation-like alteration was accompanied by decreased level of phospho-MLC, thus implying a CK2 role in regulation of actomyosin cytoskeleton. Our results suggest an important role of CK2 in the control of cell contractility and motility, which may account for suppressing effect of CK2 inhibition on retinal neovascularization. Together, our data implicate protein kinase CK2 for the first time in stellation-like morphological transformation.

Abstract
Plans to centralise paediatric surgery in Ireland have potentially significant implications for service provision and surgical training. study assesses the workload of paediatric surgery in a district hospital over a five-year period. Paediatric surgical admissions and procedures at Mayo General Hospital from January 2006 - December 2010 were reviewed. Data was obtained from the Hospital inpatient enquiry (HIPE) systems and theatre logbooks. 4,255 surgical procedures were performed in 3981 paediatric patients, accounting for 7.4% of the total surgical workload. 2,578 (65%) of cases were elective and 1403 (35%) of paediatric surgery was performed in the emergency setting; paediatric appendicectomy was the most commonly performed procedure (n = 554) with a complication rate of 2.5%. There were no paediatric surgery related mortalities. Paediatric surgery represents a significant part of the surgical workload. There is a continued need for general paediatric surgical provision in this regional setting, supported by access to specialist centres for complicated paediatric surgery.

Abstract
The metabolic syndrome, which is characterized by a constellation of fasting hyperglycemia, hypertriglyceridemia, low HDL cholesterol, hypertension, and/or abdominal obesity, is a risk factor for the development of coronary artery disease (CAD) and cardiovascular events. We evaluated interrelationships between angiographic CAD and the metabolic syndrome, in 478 patients who were referred for coronary angiography to evaluate suspected myocardial ischemia in the department of cardiology of BSMMU between June 2007 and May 2008. We applied the criteria for the metabolic syndrome proposed by ATP III guideline. Study populations were divided into two groups on the basis of presence or absence of metabolic syndrome. Age was similar in both groups. Body mass index (BMI) was higher (26.22 ± 1.94 vs. 22.07 ± 1.55) in metabolic syndrome group (p ≤ 0.0001). All parameters, waist circumference (103.16 ± 10.21 vs. 91.45 ± 7.61) cm, blood pressure both systolic (141.34 ± 21.49 vs. 127.94 ± 13.01) and diastolic (86.8 5 ± 8.42 vs. 79.28 ± 7.77) mm of Hg, serum triglyceride (248.32 ± 77.88 vs. 128.35 ± 19.00)mg/dl, fasting blood glucose (125.40 ± 22.86 vs. 95.65 ± 10.63)mg/dl were significantly higher in metabolic syndrome group (p value=0.0001), whereas HDL (33.10 ± 6.55 vs. 39.30 ± 6.17)mg/dl was lower (p value = 0.0001). More subjects in metabolic syndrome were having type B (55.60% vs. 31.00%) and type C (9.50% vs. 2.70%) lesion as compared to non-metabolic syndrome group. Involvement of left main artery was more (4.80% vs. 0.90%) in metabolic syndrome group. Metabolic syndrome has primary predictive ability for CAD. A metabolic profile should form part of the risk assessment in all patients with coronary disease, not just those who are obese.

Abstract
OBJECTIVE Procedural outcomes can be used to assess the performance of specialists and trainees. This article establishes a systematic evidence base for the safety of training in the operating theatre. It also explores the possibility of using early, intermediate and late procedural outcomes of cardiac surgical operations to evaluate the performance of the clinicians and the healthcare system. METHODS Medline, EMBASE and PsycINFO databases were searched. Comparative studies evaluating quality indicators of cardiac surgical procedures (coronary artery bypass grafting (CABG) and valve surgery) were included. guidelines from the preferred reporting items for systematic reviews and meta-analyses (PRISMA) were used. RESULTS Fourteen studies met the inclusion criteria. For CABG, meta-analysis of outcomes did not show any significant differences between the technical and non-technical skills of trainees versus specialists apart from bypass time (less for specialists) and intensive care unit (ICU) length of stay (less for trainees). Studies reporting outcomes on valve surgery also did not report any statistically significant differences amongst the outcomes. CONCLUSION This systematic review did not discern any significant differences between the procedural outcomes of trainees and specialists, which indicates that trainees are safe to operate under senior supervision. In addition, this article recommends that various procedural outcomes can be used to evaluate the performance of clinicians and healthcare systems. Prospective studies need to be performed, taking into account the specific contribution of trainees and specialists during the procedure. This will give a clearer indication of safety and performance of trainees and specialists in the operating theatre.

Abstract
This prospective randomized, controlled trial was done to evaluate the efficacy of trimetazidine in the prevention of contrast induced nephropathy in patients with raised serum creatinine levels undergoing coronary angiogram. This study was performed in the Department of Cardiology, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh from April 2009 to March 2010. Contrast-induced nephropathy (CIN) is a serious complication of coronary angiography that is associated with considerably increased mortality and morbidity, including the need for short-term haemodialysis, extended hospitalisation and permanent impairment of renal function. Trimetazidine (TMZ) has been described as a cellular anti-ischaemic agent. This study was trial with 400 patients. Among them 200 patients treated with trimetazidine plus hydration with normal saline and 200 patients (control) given hydration by normal saline only. It was found that the incidence of CIN was significantly (p<0.05) reduced by trimetazidine administration with saline in comparison with saline alone in patients undergoing coronary angiogram (4% vs. 14%).

Abstract
Patients with systemic lupus erythematosus were asked to report their perceptions as to whether stress can trigger disease flares. A total of 54 patients treated at two District General Hospitals in Essex were included in the analysis. They were 4 males and 50 females and were 20 Caucasians, 22 Asians, and 12 Africans/Afro-Caribbean. Thirty-three of 54 patients (61.1%) reported stress to be a trigger for disease flares. Although most (85%) of the Caucasian patients reported that stress triggered their disease flares, only 50% of the African/Afro-Caribbean patients and 45.4% of the Asian patients reported stress as a trigger for disease flares. No correlation was found between reported number of flares per year and characteristics such as age (P = 0.4), age at diagnosis (P = 0.8), age at disease onset (P = 0.6), or disease duration (P = 0.2). A trend towards a significant correlation was observed between the number of reported flares per year and the number of children a patient has (P = 0.07).
