The Humoral Immunity Response of Dog Vaccinated with Oral Sag2 and Parenteral Rabisin and Rabivet Supra92

This research aims to determine whether SAG2 oral vaccine induced antibody response as high as that of parenteral vaccine (Rabisin and Rabivet Supra 92). The experimental design applied was randomized pre and post control group design with 4 treatments (oral SAG2 vaccine, parenteral rabisin, parenteral Rabivet Supra 92 and control without vaccination) and with 9 replication. As many as 36 kampung dogs used and the anti rabies antibody was determined by enzyme-linked immunosorbent assay (ELISA) at day 0, 21, 56, 84, 119, and 147 post vaccination. The antibody titer induced by oral SAG2 vaccine raised more slowly but persisted longer than parenteral vaccine. On day 21 after vaccination, the average antibody titers induced by oral SAG2 vaccines (0.501 IU/ml) was still significantly lower than those induced by parenteral Rabisin (3.504 IU/ml) and Rabivet Supra92 (2.545 IU/ml). However, by day 119 after vaccination the average antibody titer induced by SAG2 oral vaccine (0.889 IU/ml) was significantly higher (p <0.05) as compared to those of parenteral Rabisin (0.625 IU/ml) and Rabivet Supra 92 (0.223 IU/ml). The antibody response induced by SAG2 oral vaccine appears to persist longer than parenteral vaccines and it can therefore be used as an alternative vaccine to combat rabies in animals, especially for dogs kept in free range

The High Plasma Retinol Binding Protein 4 Level as a Risk Factor Consequently of Type 2 Diabetes Mellitus of Abdominal Obesity

Abdominal obesity (Ab-Ob) related to cardiometabolic risk, that is riskfactor constellation for succeeded cardiovasculer disease and type 2 DiabetesMellitus (DM). That factors such as atherogenic dislipidemia, hypertension,hyperglycemia, protrombotic state, and proinflammation state. Type 2 DMcharacterised by insulin resistance (IR). Plasma levels of retinol binding protein 4(RBP4) that is secreted by adipocytes are increased in insulin resistance (IR) state.Experiment in mice suggest that elevated RBP4 level cause IR. Although theunderlying mechanism is not clearly understood, RBP4 considered playimportance role consequently of type 2 DM in Ab-Ob.This research was carried out to determine the role of high plasma RBP4level as a risk factor consequently of type 2 DM in Ab-Ob. The research wasconducted by cross sectional analytic in 81 patients with Ab-Ob and case controlstudy with matching on 33 patients with Ab-Ob type 2 DM as cases and 33patients with Ab-Ob non type 2 DM as control. The plasma of TNF-?, sTNFR1,and RBP4 levels was measured by ELISA. IR status of the patients wasdetermined by HOMA-IR, whereas the ?-cell function was determined byHOMA-B. Ab-Ob was defined by using criteria for Asian peoples (male WC ? 90cm; female WC ? 80 cm). The result of 81 patients with Ab-Ob showed that bothplasma of TNF-? and sTNFR1 levels were significant positive correlated withplasma RBP4 level (coeficient correlation r = 0,294; p = 0,008 dan r = 0,458; p =<0,001 respectively). In addition, the plasma of RBP4 level significantly positivecorrelation with HOMA-IR (r = 0,450; p = 0,000) and significantly negativecorrelation with HOMA-B (r = -0,564; p = <0,001). In the matched case-controlstudy, it was shown that mean plasma of RBP4 level of type 2 DM group (76,08 ±16,84 ?g/ml) statistically higher than that without type 2 DM group (41,13 ±14,75 ?g/ml) (p = <0,001). The odds ratio higher plasma of RBP4 level was 5,426(CI 95%; 1,343 – 21, 928) statistically significant for increases risk type 2 DM (p= < 0,05). It has been proven that RBP4 was a dominant and consisten risk factor(66.9%, p = < 0.001) which influenced the incidence of type 2 DM in Ab-Ob. It can be concluded that high plasma of RBP4 level have a greater risk tosuffered from type 2 DM compared to low plasma of RBP4 in Ab-Ob. The highplasma of RBP4 level is most dominant and consistent risk factor consequently oftype 2 DM. These mechanism could behind the association between high plasmaof RBP4 level and type 2 DM

Interleukin -2 ( Il-2 ) and Gamma Interferon ( Ifn ? ) of Lymphocyte Culture Supernatant in Iron Deficiency Anemia Patients with Infection

Iron is an essential nutrient for every living cells because of it role as molecule fortransport of oxygen, as well as DNA synthesis through synthesis of ribonucleotidereductase. Iron deficiency anemia patients, especially pregnant women and children aremore susceptible to infection because of deterioration of their immune response. This wassupported by findings of decreased in phagocytic activities of white blood cells and Tcelllymphocyte proliferation impairment. Iron deficiency anemia (IDA) patients alsoaffect working capacities hence diminishing working outcomes. Although the underlyingmechanism of immune defect in iron deficiency anemia is not clearly understood,multifactor events considered play their contributing roles such as abnormality ofribonucleotide reductase enzym, impairment of T-cell proliferation and activities, alteredcytokine production of IL-2 and IFN?.The study was done to asses the relationship of IL-2 and gamma IFN withinfection in IDA patients on lymphocyte culture supernatant of IDA patients. Study wasconducted on cross-sectional analytic design. Sixty-four iron deficiency anemia patientstreated in Sanglah General Teaching Hospital were recruited, and 31 (48.4%) out of 64IDA patients were man and 33 (51.6%) women, have been selected for the study. Thisstudy found 17 (26.7%) IDA patients with infection, aged 38 ± 14.48 years and 47(73.3%) IDA patients without infection, with age average of 40.5 ± 14.4 years. Allvariables of data characteristics examined did not indicate any statistical significantdifference between group of IDA patients with infection and those without infection. Theaverage level of hemoglobin between the two groups did not differ statistically. Similarresult was obtained if samples were differentiated into severe (Hb< 7g/dl) and mildanemia. The study also revealed that there were no differences of cytokine level observedbetween older and younger age (upper and below 44.5 years) in IDA patients withinfection and without infection. Furthermore, no differences of cytokine level were foundbased on gender between IDA male 10.9 (8.60 – 12,65) (pg/l) patients and IDA femalepatients 10.6 (7.50 – 13.43) (pg/l) with Z -0.490, p =0.624. Nevertheless, significantdifferences were noted between supernatant of IL-2 and IFN? in IDA patients withinfection when compared to IDA patients without infection (Z= - 2.509, p= 0.012 forsupernatant IL-2; and Z= -2.569, p= 0.010 for supernatant IFN?).The study conclusion is that level of IL-2 and IFN? from lymphocyte culturesupernatant of patient suffered from IDA with infection is significantly lower whencompared to IDA patient without infection. It therefore summarized that lower level ofIL-2 and gamma IFN in patients suffered from iron deficiency impaired their immune response to certain infections therefore this findings support the theory that IDA patientsmore susceptible to get infected

Triethylphosphite as a network forming agent enhances in-vitro biocompatibility and corrosion protection of hybrid organic-inorganic sol-gel coatings for Ti6Al4V alloys

The biocompatibility and life of metallic implants can be enhanced through improving the biocompatibility and corrosion protection characteristics of the coatings used with these materials. In this study, triethylphosphite (TEP) was used to introduce phosphorus into organic-inorganic hybrid silica based sol gel coatings prepared using γ-methacryloxypropyltrimethoxysilane and tetramethylorthosilicate. Addition of TEP dramatically increased the rate of intermolecular condensation and resulted in materials showing greater cross linking. Protein (fibrinogen) uptake, osteoblast in vitro biocompatibility and corrosion resistance was enhanced in coatings containing TEP. Although higher concentrations of phosphorus supported the greatest improvement in biocompatibility, a compromise in the phosphorus concentration used would be required if corrosion resistance was most desirable parameter for optimisation. Films prepared by dip coating on Ti6Al4V alloys from these sols offer a promising alternative to wholly metallic prostheses

Konsekvenser for Ellingsen Seafood ved at ferjesambandet Skutvik-Svolvær via Skrova har blitt redusert

1.1.2008 ble Lofotens fastlandsforbindelse (LOFAST) åpnet og som en konsekvens av dette ble ferjetilbudet mellom Skutvik- Svolvær via Skrova redusert. Hovedårsaken til dette, var at større andeler av trafikken som da gikk med Skutviksambandet nå skulle genereres gjennom ferjesambandene Bodø- Moskenes i sør og Lødingen- Bognes i nord. På bakgrunn av dette har vi i denne oppgaven belyst hva som blir konsekvensene for fiskeribedriften Ellingsen Seafood lokalisert på Skrova. Ut fra dette har vi drøftet følgende hovedproblemstilling: Hvilke konsekvenser har det reduserte ferjetilbudet hatt for Ellingsen Seafood? Våre funn viser at Ellingsen Seafood har fått relativt store kostnadsøkninger som følger av det reduserte ferjetilbudet. De største kostnadsøkningene kommer som følger av at transportøren av fiskekasser har måttet lagt om transportruten sin. Dette har ført til en markant økning i prisen på fiskekasser. Den nye transportruten til transportøren har også ført til økte lønnskostnader, som følger av sene leveringer. Videre har det reduserte ferjetilbudet ført til økt usikkerhet for leveringer, noe som har gjort at Ellingsen Seafood har økt lageret på fiskekasser. I tillegg til hovedproblemstillingen, har vi redegjort i to underproblemstillinger, hvilke konsekvenser det reduserte ferjetilbudet har hatt for det øvrige næringslivet på Skrova, samt hvilke konsekvenser lokalbefolkningen har hatt. Våre funn viser her at det er blitt vanskeligere for kundene å komme seg til Skrova. Dette på grunn av at mange kunder kommer sørfra og den reduserte frekvensen på strekningen gjør at Skrova blir mindre tilgjengelig. Turistnæringen har merket en viss nedgang i omsetning. Dette skyldes hovedsakelig at færre kommer innom Skrova på snarvisitter. For lokalbefolkningen har det reduserte ferjetilbudet ført til færre valgmuligheter for transport hvis de skal sørover. Den lave frekvensen fører derfor til at lokalbefolkningen må velge alternative reiseruter, noe som medfører lengre reisetid og høyere betalbare kostnader

Designing programs for eliminating canine rabies from islands: Bali, Indonesia as a case study

<p>Background: Canine rabies is one of the most important and feared zoonotic diseases in the world. In some regions rabies elimination is being successfully coordinated, whereas in others rabies is endemic and continues to spread to uninfected areas. As epidemics emerge, both accepted and contentious control methods are used, as questions remain over the most effective strategy to eliminate rabies. The Indonesian island of Bali was rabies-free until 2008 when an epidemic in domestic dogs began, resulting in the deaths of over 100 people. Here we analyze data from the epidemic and compare the effectiveness of control methods at eliminating rabies.</p> <p>Methodology/Principal Findings: Using data from Bali, we estimated the basic reproductive number, R0, of rabies in dogs, to be ~1·2, almost identical to that obtained in ten–fold less dense dog populations and suggesting rabies will not be effectively controlled by reducing dog density. We then developed a model to compare options for mass dog vaccination. Comprehensive high coverage was the single most important factor for achieving elimination, with omission of even small areas (<0.5% of the dog population) jeopardizing success. Parameterizing the model with data from the 2010 and 2011 vaccination campaigns, we show that a comprehensive high coverage campaign in 2012 would likely result in elimination, saving ~550 human lives and ~$15 million in prophylaxis costs over the next ten years.</p> <p>Conclusions/Significance: The elimination of rabies from Bali will not be achieved through achievable reductions in dog density. To ensure elimination, concerted high coverage, repeated, mass dog vaccination campaigns are necessary and the cooperation of all regions of the island is critical. Momentum is building towards development of a strategy for the global elimination of canine rabies, and this study offers valuable new insights about the dynamics and control of this disease, with immediate practical relevance.</p&gt

Molecular genetics of hemophilia A: Clinical perspectives

Since the publication of the sequence of the factor VIII (F8) gene in 1984, a large number of mutations that cause hemophilia A have been identified and a significant progress has been made in translating this knowledge for clinical diagnostic and therapeutic purposes. Molecular genetic testing is used to determine the carrier status, for prenatal diagnosis, for prediction of the likelihood of inhibitor development, and even can be possibly used to predict responsiveness to immune tolerance induction. Phenotypic heterogeneity of hemophilia is multifactorial, mainly related to F8 mutation but other factors contribute especially to coinheritance of prothrombotic genes. Inhibitordevelopment is mainly related to F8 null mutations, but other genetic and non genetic factors could contribute. This review will focus on the genetic aspects of hemophilia A and their application in the clinical setting and the care of patients and their familie

Review: Cytokines in Gaucher disease: Role in the pathogenesis of bone and pulmonary disease

Gaucher disease (GD) is the most frequently encountered lysosomal storage disease causedby inborn defects of themembrane-bound lysosomal enzyme, acid b-glucosidase or glucocerebrosidase. This defective activity causes an accumulation of glucocerebroside (glucosylceramide) in the lysosomes of cells derived from the monocyte/macrophage lineage. Glucocerebroside-engorged cells, termed Gaucher cells, infiltrate various organs, leading to multisystemic abnormalities. The mechanisms by which systemic and organ-specific involvement is propagated or initiated remain unclear. Studies are increasingly recognizing the role of immune dysregulation and inflammation in the pathogenesis of Gaucher disease. Many cytokines have been reported as mediators of tissue damage in Gaucher disease. Bone and lung disease are serious causes of morbidity in non neuronopathic Gaucher disease. The progress in the understanding of the pathogenesis or relevant mechanism(s) of Gaucher disease is providing insights into additional therapeutic targets, enabling the potential for optimized patient outcomes with the use of adjunctive or supplemental agents.KEYWORDS : Cytokines; Gaucher disease; Pathogenesis; Bone disease; Pulmonary diseas

Forecasting Global Energy Commodity Prices: A Systematic Approach to Forecast Combination

Masteroppgave(MSc) in Master of Science in Business, Economics - Handelshøyskolen BI, 2024We investigate the accuracy of different forecasts of the global real price of oil and natural gas, on a monthly basis. In particular, we investigate whether combinations of forecasts including newer models are more accurate than those using only older state-of-the-art models from the literature. Our new model combinations outperform previous state-of-the-art models when predicting both real oil and natural gas prices. For oil, the new combinations reduce MSPE ratios relative to the no-change forecast by an average of 4 percentage points compared to the old combinations. For natural gas, the reductions are on average 6 percentage points. Additionally, we find that using equal weights provide the highest accuracy for real oil price forecasts. On the other hand, for the real price of natural gas, the lowest MSPEs are achieved with performance-based weights derived from forecast errors from the past 24 months. We also examine how using different indicators of global activity in our VAR and BVAR models impacts the combined forecasts. We find that the most accurate forecasts are obtained using the real commodity price factor (RCPF) for the real price of oil and world industrial production (WIP) for the real price of natural gas. Moreover, we find that using production-based VAR and BVAR models in our combination has the overall best performance for the real price of oil. In contrast, using consumption-based VAR and BVAR models is best for the combined forecasts of the real price of natural gas

Effectiveness and cost effectiveness of pharmacist input at the ward level: a systematic review and meta-analysis

Background Pharmacists play important role in ensuring timely care delivery at the ward level. The optimal level of pharmacist input, however, is not clearly defined. Objective To systematically review the evidence that assessed the outcomes of ward pharmacist input for people admitted with acute or emergent illness. Methods The protocol and search strategies were developed with input from clinicians. Medline, EMBASE, Centre for Reviews and Dissemination, The Cochrane Library, NHS Economic Evaluations, Health Technology Assessment and Health Economic Evaluations databases were searched. Inclusion criteria specified the population as adults and young people (age >16 years) who are admitted to hospital with suspected or confirmed acute or emergent illness. Only randomised controlled trials (RCTs) published in English were eligible for inclusion in the effectiveness review. Economic studies were limited to full economic evaluations and comparative cost analysis. Included studies were quality-assessed. Data were extracted, summarised. and meta-analysed, where appropriate. Results Eighteen RCTs and 7 economic studies were included. The RCTs were from USA (n=3), Sweden (n=2), Belgium (n=2), China (n=2), Australia (n=2), Denmark (n=2), Northern Ireland, Norway, Canada, UK and Netherlands. The economic studies were from UK (n=2), Sweden (n=2), Belgium and Netherlands. The results showed that regular pharmacist input was most cost effective. It reduced length-of-stay (mean= -1.74 days [95% CI: -2.76, -0.72], and increased patient and/or carer satisfaction (Relative Risk (RR) =1.49 [1.09, 2.03] at discharge). At £20,000 per quality-adjusted life-year (QALY)-gained cost-effectiveness threshold, it was either cost-saving or cost-effective (Incremental Cost Effectiveness Ratio (ICER) =£632/ QALY-gained). No evidence was found for 7-day pharmacist presence. Conclusions Pharmacist inclusion in the ward multidisciplinary team improves patient safety and satisfaction and is cost-effective when regularly provided throughout the ward stay. Research is needed to determine whether the provision of 7-day service is cost-effective.Peer reviewe
