Abstract
The Hodgkin/Reed-Sternberg cells of classical Hodgkin lymphoma (HL) are characterised by the aberrant activation of multiple signalling pathways. Here we show that a subset of HL displays altered expression of sphingosine-1-phosphate (S1P) receptors (S1PR)s. S1P activates phosphatidylinositide 3-kinase (PI3-K) in these cells that is mediated by the increased expression of S1PR1 and the decreased expression of S1PR2. We also showed that genes regulated by the PI3-K signalling pathway in HL cell lines significantly overlap with the transcriptional programme of primary HRS cells. Genes upregulated by the PI3-K pathway included the basic leucine zipper transcription factor, ATF-like 3 (BATF3), which is normally associated with the development of dendritic cells. Immunohistochemistry confirmed that BATF3 was expressed in HRS cells of most HL cases. In contrast, in normal lymphoid tissues, BATF3 expression was confined to a small fraction of CD30-positive immunoblasts. Knockdown of BATF3 in HL cell lines revealed that BATF3 contributed to the transcriptional programme of primary HRS cells, including the upregulation of S1PR1. Our data suggest that disruption of this potentially oncogenic feedforward S1P signalling loop could provide novel therapeutic opportunities for patients with HL.

Abstract
Diltiazem hydrochloride (DTZ) is a calcium channel antagonist depicted by extensive first pass metabolism and low oral bioavailability. The aim of this work was to develop niosomes for potential nasal delivery of DTZ. Niosomes protect hydrophilic drugs inside their core while nasal route offers both rapid onset and evasion of first-pass metabolism. Niosomes were prepared using a combination of Span 60 or Brij-52 with cholesterol (CHOL) in different molar ratios followed by determination of entrapment efficiency, particle size and in vitro drug release. A parallel design was adopted to evaluate the pharmacokinetic performance of DTZ-loaded niosomes in male Wistar rats. Non-compartmental analysis was performed where Cmax, Tmax, t1/2, MRT, area under the release curve (AUC) and Ke were assessed. The prepared niosomes were spherical with mean particle size 0.82-1.59 μm. Span 60-cholesterol niosomes (1:1 molar ratio) showed the highest entrapment and release efficiencies. In vivo study revealed an increase in MRT, t1/2 and AUC with a decrease in Ke. In conclusion, nasal niosomal formulation of DTZ expressed suitable pharmacokinetic parameters and bioavailability through prolonged duration of action inside the body as well as low rate of elimination depicting a promising alternate to the conventional oral route.

Abstract
BACKGROUND The Nigerian transplantation program is evolving but is currently over-reliant on living donors. If deceased donation is to be viable in Nigeria, it is important to ascertain the views of the public. The objective of the study was to explore the knowledge, attitudes, and behavior of Nigerian international students toward organ donation. METHODS A cross-sectional study was conducted among Nigerian international students of the University of Bedfordshire through the use of a modified self-administered questionnaire. The participants were recruited by means of purposive sampling. RESULTS Of the 110 questionnaires distributed, 103 were returned fully completed (response rate = 93.6%). A significant majority (93.2%) of the participants are aware of organ donation, and 76.7% have a good knowledge on the subject. Furthermore, more than half (52.8%) of the participants have a positive attitude toward organ donation, and less than half (42.8%) have favorable behavior toward it. Higher knowledge does not correlate to either positive attitude or behavior, but a positive attitude is correlated with favorable behavior toward donation. CONCLUSIONS The attitudes and behavior of the respondents toward organ donation is not commensurate with the level of knowledge they possess. This highlights the urgent need for well-structured educational programs on deceased organ donation.

Abstract
Animal diseases and zoonoses abound among pastoralist livestock, which is composed of cattle, sheep, goats, yak, camels, llamas, reindeer, horses and donkeys. There is endemic and, periodically, epidemic transmission of highly contagious viral and bacterial diseases in Africa, Asia and Latin America. Pastoralist livestock is often multiparasitised with endo- and ectoparasites, as well as being affected by vectorborne viral and protozoal diseases. Pastoral livestock can be a reservoir of such diseases and can also, conversely, be at risk from exposure to wildlife reservoirs. Public and private animal health services currently underperform in almost all pastoral areas due to structural reforms and lack of income, as indicated in assessments of national Veterinary Services by the World Organisation for Animal Health. Control of infectious disease in industrialised countries has been achieved through large-scale public funding of control measures and compensation for culled stock. Such means are not available in pastoralist areas of most low- and middle-income countries (LMICs). While the cost-effectiveness and profitability of the control of animal diseases and zoonoses is less of a consideration for industrialised countries, in the experience of the authors, understanding the economic implications of a control programme is a prerequisite for successful attempts to improve animal health in LMICs. The incremental costs of animal disease control can potentially be shared using crosssector assessments, integrated control, and regional coordination efforts to mitigate transboundary disease risks. In this paper, the authors discuss cost-effective animal disease and zoonoses control in LMICs. It illustrates frameworks and examples of integrated control and cross-sector economics, showing conditions under which these diseases could be controlled in a cost-effective way.

Abstract
Respiratory diseases represent a major healthcare burden worldwide. Lung transplantation (LTx) is the "gold standard" for end-stage patients, strongly limited by shortage of available/suitable donor lungs. Normothermic ex vivo lung perfusion (EVLP) has significantly increased the number of lungs suitable for transplantation. Steen solution is used for EVLP, but the mechanisms involved in its beneficial properties remain to be clarified. We investigated the effects of Steen solution in an in vitro protocol of cold starvation and normothermic recovery on human lung spheroids, named pneumospheres (PSs), containing epithelial/basal cells, and on endothelial human umbilical vein endothelial cells (HUVEC). Steen solution significantly preserved the viability of PSs, reduced reactive oxygen species (ROS) release by PSs and HUVECs, decreased NADPH-oxidase (NOX) activity in PSs, and reduced inflammatory cytokines expression levels in HUVECs. Steen solution was able to specifically reduce NADPH oxidase 2 (NOX2) isoform activation, particularly in PSs, as detected by soluble-NOX2 peptide and p47-phosphorylation. Interestingly, a specific NOX2 inhibitor could partly mimic the pro-survival effect of Steen on PSs. We provide the first evidence that Steen solution can preserve lung epithelial/progenitor cells viability partially through NOX2 downregulation, and exert antioxidant effects on parenchymal cells, with consequent ROS reduction. These results suggest that NOX2 inhibition might be an additional strategy to reduce cellular damage during LTx procedures.

Abstract
<p>Layered double hydroxide of Mg-Al-nitrate system (LDH) was prepared and its heat<strong>-</strong>treated products (LDHTs) were obtained by calcining the LDH at 250–750 °C, for 5 hours at atmospheric condition. The LDH and the LDHTs were used as an inorganic host for the intercalation of AQ2 via ion exchange or memory effect property by exposing the LDH and LDHTs in aqueous solution containing an anion, anthraquinone-2-sulfonate (AQ2) for the formation of an organic-inorganic layered nanohybrid materials. X-ray diffractograms showed that the layered structure of LDH collapsed when it was heated at around 350 °C, and an oxide phase, MgAl<sub>2</sub>O<sub>4</sub> appeared. Due to the memory effect property, the regeneration of LDH from LDHT was observed and at the same time the AQ2 was intercalated when LDHT was treated with the aqueous solution containing AQ2. As a result, formation of an organic-inorganic layered nanohybrid material was also observed. Similarly, the same material can be formed by ion exchange of LDH with AQ2. The basal spacing of LDH was found expanded from 8.1 Å to around 20 Å in the resulting nanohybrid. This is to accommodate a bigger size of the AQ2 moiety with specific orientation inside the interlamella of the inorganic layered structure that warrants the layer expansion. Incomplete intercalation and ion exchange process resulted in a mixed LDH and a nanohybrid phase as observed in the PXRD pattern of the resulting material.</p>

Abstract
INTRODUCTION The Rehabilitation and Exercise Oncology model of care (ActivOnco) was established to optimize cancer survivorship through exercise prescription and active lifestyle promotion, providing a transition of care from hospital to community. Patients having any cancer diagnosis, stage of disease, and treatment were eligible for evaluation and exercise prescription upon deterioration of performance status. The team of professionals included hospital-based physiotherapists proactively screening for rehabilitation needs, loss of functional independence, and exercise eligibility, plus exercise specialists in a community-based Wellness Centre to provide follow-up or direct access for post-treatment or non-complex patients. METHODS From January 2011 to December 2015, the hospital team assessed 1635 patients representing all major cancer sites, and the Wellness Centre team evaluated and prescribed exercise for 1066 participants. Primary interventions provided were education about fatigue management, physical activity promotion, exercise prescription, fracture risk reduction, referral to specialized follow-up services (for example, occupational therapy, lymphedema clinic), and coordination for mobility aids and paratransit services. RESULTS AND CONCLUSIONS Implementation of the ActivOnco model of care showed that exercise alone is not a panacea for all functional deterioration associated with the cancer trajectory and its treatment. However, screening to identify rehabilitation needs combined with exercise prescription can effectively improve the quality of survivorship in cancer patients. Program developments are limited by the cost of human resources, lack of hospital-based physical resources, and lack of public funding, all of which significantly limit the scope and development of appropriate services.

Abstract
Hereditary Protein S (PS) deficiency is a rare coagulation disorder associated with an increased risk of venous thrombosis (VT). The PS Heerlen (PSH) mutation is a rare S501P mutation that was initially considered to be a neutral polymorphism. However, it has been later shown that PSH has a reduced half-life in vivo which may explain the association of PSH heterozygosity with mildly reduced levels of plasma free PS (FPS). Whether the risk of VT is increased in PSH carriers remains unknown. We analyzed the association of PSH (rs121918472 A/G) with VT in 4,173 VT patients and 5,970 healthy individuals from four independent case-control studies. Quantitative determination of FPS levels was performed in a subsample of 1257 VT patients. In the investigated populations, the AG genotype was associated with an increased VT risk of 6.57 [4.06–10.64] (p = 1.73 10−14). In VT patients in whom PS deficiency was excluded, plasma FPS levels were significantly lower in individuals with PSH when compared to those without [72 + 13 vs 91 + 21 UI/dL; p = 1.86 10−6, mean + SD for PSH carriers (n = 21) or controls (n = 1236) respectively]. We provide strong evidence that the rare PSH variant is associated with VT in unselected individuals.

Abstract
The ultra-bright femtosecond X-ray pulses provided by X-ray Free Electron Lasers (XFELs) open capabilities for studying the structure and dynamics of a wide variety of biological and inorganic systems beyond what is possible at synchrotron sources. Although the structure and chemistry at the catalytic sites have been studied intensively in both biological and inorganic systems, a full understanding of the atomic-scale chemistry requires new approaches beyond the steady state X-ray crystallography and X-ray spectroscopy at cryogenic temperatures. Following the dynamic changes in the geometric and electronic structure at ambient conditions, while overcoming X-ray damage to the redox active catalytic center, is key for deriving reaction mechanisms. Such studies become possible by using the intense and ultra-short femtosecond X-ray pulses from an XFEL, where sample is probed before it is damaged. We have developed methodology for simultaneously collecting X-ray diffraction data and X-ray emission spectra, using an energy dispersive spectrometer, at ambient conditions, and used this approach to study the room temperature structure and intermediate states of the photosynthetic water oxidizing metallo-protein, photosystem II. Moreover, we have also used this setup to simultaneously collect the X-ray emission spectra from multiple metals to follow the ultrafast dynamics of light-induced charge transfer between multiple metal sites. A Mn-Ti containing system was studied at an XFEL to demonstrate the efficacy and potential of this method.

Abstract
Identifying women at risk of venous thrombosis (VT) under combined oral contraceptives (COC) is a major public health issue. The aim of this study was to investigate in COC users the impact on disease of genetic polymorphisms recently identified to associate with VT risk in the general population. Nine polymorphisms located on KNG1, F11, F5, F2, PROCR, FGG, TSPAN and SLC44A2 genes were genotyped in a sample of 766 patients and 464 controls as part of the PILGRIM (PILl Genetic Risk Monitoring) study. Cases were women who experienced an episode of documented VT during COC use, while controls were women with no history of VT using COC at the time of inclusion. Among the studied polymorphisms, only F11 rs2289252 was significantly associated with VT. The F11 rs2289252-A allele was associated with a 1.6-fold increased risk of VT (p < 0.0001). Besides, the combination of the rs2289252-A allele with non-O blood group, present in 52% of the cohort, was associated with an odds ratio of 4.00 (2.49-6.47; p < 10-4 ). The consideration of this genetic risk factor could help to better assess the risk of VT in COC users.

Abstract
BACKGROUND Leak after laparoscopic sleeve gastrectomy (LSG) is a serious complication. No clear algorithm has been described for management. METHODS We reviewed our prospective database for all leaks after LSG treated at the Bariatric and Metabolic Institute (BMI) Abu Dhabi from 2010 to 2014. Our management algorithm is based on the timing of the LSG leak, nutritional status of the patient, and the presence of stenosis or peritonitis. Acute leaks with or without peritonitis are treated by operatively or utilizing endoscopic stenting, respectively. LSG leaks with stenosis not amenable to endoscopic stenting are treated with laparoscopic Roux en Y esophagojejunostomy (LRYEJ). RESULTS We performed 236 LSG without a leak, and 14 LSG leaks were referred to our unit. Mean age was 35.6 years, and 50 % of patients were males. Mean BMI was 37 kg/m(2). The patients presented on average 13.9 weeks after LSG. Enteral feeding was used as the primary nutrition route in 85.5 % of patients. Our management strategy was operative in 78.4 % of patients (jejunostomy feeding in 57 % and LRYEJ in 21.4 % of patients) and conservative with or without stents in 21.6 % of patients. Mean in hospital length of stay (LOS) was 5.6 weeks. Our reoperation rate was 7 %. There were no mortalities and one patient 7 % developed pulmonary embolism. None of the patients treated returned with a leak or collection after a mean follow up of 23.6 months. CONCLUSION Treating leaks following LSG based on the timing of presentation, presence of stricture, and malnutrition is safe and effective.
