Both IFN-γ and IL-4 Induce MHC Class II Expression at the Surface of Mouse Pro-B Cells

Pro-B cells are early B-cell progenitors that retain macrophage potential. We have studied MHC class II molecules and invariant chain inducibility on four class II negative mouse pro- B-cell clones. We analyzed the effects of IL-4 and IFN-γ, which represent the major inducers of class II in the B-lymphoid and monocytic/macrophage lineages, respectively. After 48 h of treatment with either cytokine, three pro-B-cell clones (C2.13, A1.5, and F2.2) expressed intracellular invariant chain and cell-surface class II molecules. One clone (D2.1) remained negative. As already reported, more differentiated 70Z/3 pre-B cells were inducible by IL-4 only. These data suggest that the induction of class II and invariant-chain genes are subject to regulation throughout B-cell differentiation

Expression of Functional MHC Class II Molecules By a Mouse Pro-B Cell Clone

We describe here the G12 pro-B cell clone that has been isolated from an IL-7 transgenic mouse. This clone has the phenotype B220+, BP-1+ , HSA +, CD43+ λ5+ , and CD25-, and has its Ig locus in a germline configuration. G12 cells spontaneously express cell-surface MHC class II molecules, although to a much lesser extent than the mature M12.4.1 B-cell lymphoma. G12 cells can process and present the native Hen Egg Lysozyme (HEL) to an MHC class II-restricted T-cell hybridoma. The efficiency of presentation is inferior to that obtained with M12.4.1 cells. This is the first report where a pro-B cell can serve as APC in an MHC class II-restricted presentation

The interrelationship between internal marketing, employee perceived quality and customer satisfaction – a conventional banking perspective

Abstract: This study explores how internal marketing influences employees’ perceived ability to deliver service quality in the conventional banking industry in Oman. The influence of employee perceived service quality on customer satisfaction is also established. Data was obtained from retail banking branch employees at the customer front line of conventional banks in Oman using electronic surveys. A total of 355 responses were obtained for data analysis. The measurement and structural models were measured through structural equation modelling. The findings reveal that internal price, internal promotion, and internal performance management are influencers of service quality, with the latter having a direct relationship with customer satisfaction. In addition, service quality has a positive influence on customer satisfaction in conventional banks in Oman. The findings can guide conventional banking management in Oman on how internal marketing can promote service quality, ultimately leading to positive customer satisfaction experiences

Internal marketing, service quality and customer satisfaction : an Islamic banking perspective

Abstract: Purpose – The study explores the extent to which internal marketing influences employees’ perceived ability to deliver service quality in the Islamic banking industry in Oman. Additionally, the influence of perceived service quality on customer satisfaction is established. Design/methodology/approach – Data was obtained from retail banking branch employees at the customer front line of Islamic banks in Oman using electronic and person-administered surveys, and 272 responses were deemed suitable for data analysis. The measurement and structural models were measured through Structural Equation Modelling. Findings – The findings show that internal promotion, internal process and internal purpose are enablers of employees’ perceived ability to deliver service quality in the Islamic banking industry of Oman. In addition, service quality was found to have a strong positive influence on customer satisfaction in Islamic banks. Research implications – This study demonstrates that internal product, internal price, internal promotion, internal process and internal purpose are influencers of service quality, and the latter has a direct relationship with customer satisfaction in Islamic banking. Managerial implications – The findings can guide the Islamic banking sector in Oman on how internal marketing can foster service quality, ultimately leading to positive customer satisfaction experiences. Originality/value – The internal marketing mix model is predominately a western model, which has been tested primarily in mature western markets. This study reflects on 10 internal marketing mix elements, which have been tested for the enablement of service quality and customer satisfaction in Oman

Hydrotherapy and its effects on chronic pain intensity, physical functionality and quality of life in the elderly

Chronic pain is often associated with impaired muscle strength and limited physical activity and performance, resulting in impaired physical functioning. This study aimed to determine whether voluntary participation in a structured 6-week hydrotherapy exercise programme would improve pain management, functionality and quality of life in an elderly population (n = 22; 77.7 ± 6.6 y)suffering from chronic pain and living in nursing homes in Tshwane. The experimental group (n= 13) attended hydrotherapy classes twice a week for six weeks, while the control group (n = 9)did not. Questionnaires were completed (Chronic Pain Grade, Functional Status Index, and the SF 36), and functional testing performed, in both groups at weeks 0, 3 and 6. The experimental group reported reduced pain intensity at week 3 (p = 0.051); reduced pain-induced disability at week 6 (p = 0.080); reduced assisted help required for activities of daily living (ADL) at week 3 (p = 0.040); reduced difficulty on performing ADL at week 3 (p = 0.012) and reduced pain experienced with ADL at week 3 (p = 0.007) and week 6 (p = 0.014). Improvements in upper body strength and agility were demonstrated. Improvements in sub-scales for quality of life were demonstrated at weeks 3 and 6. The control group showed no statistically significant changes in the above parameters. In conclusion, participation in structured hydrotherapy classes has been shown in this small study to be a beneficial intervention strategy for managing chronic pain in the elderly.http://www.ajol.info/journal_index.php?jid=153&ab=ajpherd2017-12-31am201

Phase II Study of BEZ235 versus Everolimus in Patients with Mammalian Target of Rapamycin Inhibitor‐Naïve Advanced Pancreatic Neuroendocrine Tumors

BACKGROUND: This phase II study investigated whether targeting the phosphatidylinositol 3‐kinase (PI3K)/mammalian target of rapamycin (mTOR) pathway via PI3K, mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2) inhibition using BEZ235 may be more effective than mTORC1 inhibition with everolimus in patients with advanced pancreatic neuroendocrine tumors (pNET) who are naïve to mTOR inhibitor therapy. METHODS: Patients with advanced pNET were randomized (1:1) to oral BEZ235 400 mg twice daily or oral everolimus 10 mg once daily on a continuous dosing schedule. The primary endpoint was progression‐free survival (PFS). Secondary endpoints included safety, overall response rate (ORR), overall survival (OS), and time to treatment failure. RESULTS: Enrollment in this study was terminated early (62 enrolled of the 140 planned). The median PFS was 8.2 months (95% confidence interval [CI]: 5.3 to not evaluable [NE]) with BEZ235 versus 10.8 months (95% CI: 8.1–NE) with everolimus (hazard ratio 1.53; 95% CI: 0.72–3.25). The most commonly reported all‐grade adverse events (>50% of patients regardless of study treatment relationship) with BEZ235 were diarrhea (90.3%), stomatitis (74.2%), and nausea (54.8%). CONCLUSION: BEZ235 treatment in mTOR inhibitor‐naïve patients with advanced pNET did not demonstrate increased efficacy compared with everolimus and may be associated with a poorer tolerability profile

Towards informed and multi-faceted wildlife trade interventions

International trade in wildlife is a key threat to biodiversity conservation. CITES, the Convention on International Trade in Endangered Species of Wild Fauna and Flora, is the primary mechanism for controlling international wildlife trade and seeks to ensure it is sustainable, relying on trade bans and controls. However, there has been little comprehensive review of the effectiveness of CITES. Here, we review typical and atypical approaches taken to regulate wildlife trade in CITES and assert that it boasts few successes. We attribute this to: non-compliance, an over reliance on regulation, lack of knowledge of listed species, ignorance of the reality of market forces, and influence among CITES actors. To more effectively manage trade we argue that interventions need to go beyond regulation and should be multi-faceted, reflecting the complexity of wildlife trade. To inform such interventions we assert an intensive research effort is needed and we outline six key research areas: (1) factors undermining wildlife trade governance at the national level, (2) determining sustainable harvest rates for CITES species, (3) gaining the buy-in of local communities in implementing CITES, (4) supply and demand based market interventions, (5) means of quantifying illicit trade, and (6) political processes and influence within CITES

Mycobacterium avium paratuberculosis infection of calves – The impact of dam infection status

Johne’s disease, caused by Mycobacterium avium subsp. paratuberculosis (MAP), is a chronic condition of dairy cattle, and is endemic in the UK. Lack of understanding of the relative importance of different transmission routes reduces the impact of control scheme recommendations. The long incubation period for Johne’s disease makes evaluation of control schemes difficult, and so this long-term cohort study offers a rare and valuable insight into the disease epidemiology. A longitudinal study was carried out following a cohort of 440 UK dairy cows in 6 herds recruited in 2012-2013. Individuals entering the milking herd were routinely monitored for the presence of MAP using quarterly milk ELISA testing. Using a Cox proportional-hazards regression model the relationship between time until first detection of infection and dam MAP status was investigated. We then compared the magnitude of the effect of dam status with that of other risk factors in order to understand its relative importance. Dam status was found to be the only observed factor that was significantly associated with time to an individual testing MAP-positive (p = 0.012). When compared to negative dams, we found a marginally significant effect of having a positive dam at time of calving, that increased the hazard of an individual testing positive by a factor of 2.6 (95% confidence interval: 0.89–7.79, p = 0.081). Further positive associations were found with dams becoming positive after the birth of the subject; a dam seroconverting within 12 months post parturition being associated with a 3.6 fold increase in hazard (95% confidence interval: 1.32–9.77, p = 0.013), and dams seroconverting more than a year after calving increased the hazard by a factor of 2.8 (95% confidence interval: 1.39–5.76, p = 0.004). These results suggest that cows may be transmitting MAP to their offspring at an earlier stage than had previously been thought, and so raise important questions about how this transmission may be occurring. The results of the study may have important practical implications for the management on-farm of the offspring of MAP-positive animals, with the potential to vastly reduce the time required to eliminate this chronic disease

Precision Measurement of the Proton and Deuteron Spin Structure Functions g2 and Asymmetries A2

We have measured the spin structure functions g2p and g2d and the virtual photon asymmetries A2p and A2d over the kinematic range 0.02 < x < 0.8 and 0.7 < Q^2 < 20 GeV^2 by scattering 29.1 and 32.3 GeV longitudinally polarized electrons from transversely polarized NH3 and 6LiD targets. Our measured g2 approximately follows the twist-2 Wandzura-Wilczek calculation. The twist-3 reduced matrix elements d2p and d2n are less than two standard deviations from zero. The data are inconsistent with the Burkhardt-Cottingham sum rule if there is no pathological behavior as x->0. The Efremov-Leader-Teryaev integral is consistent with zero within our measured kinematic range. The absolute value of A2 is significantly smaller than the sqrt[R(1+A1)/2] limit.Comment: 12 pages, 4 figures, 2 table
