Abstract
Intellectual disability (ID) is a measurable phenotypic consequence of genetic and environmental factors. In this study, we prospectively assessed the diagnostic yield of genomic tools (molecular karyotyping, multi-gene panel and exome sequencing) in a cohort of 337 ID subjects as a first-tier test and compared it with a standard clinical evaluation performed in parallel. Standard clinical evaluation suggested a diagnosis in 16% of cases (54/337) but only 70% of these (38/54) were subsequently confirmed. On the other hand, the genomic approach revealed a likely diagnosis in 58% (n=196). These included copy number variants in 14% (n=54, 15% are novel), and point mutations revealed by multi-gene panel and exome sequencing in the remaining 43% (1% were found to have Fragile-X). The identified point mutations were mostly recessive (n=117, 81%), consistent with the high consanguinity of the study cohort, but also X-linked (n=8, 6%) and de novo dominant (n=19, 13%). When applied directly on all cases with negative molecular karyotyping, the diagnostic yield of exome sequencing was 60% (77/129). Exome sequencing also identified likely pathogenic variants in three novel candidate genes (DENND5A, NEMF and DNHD1) each of which harbored independent homozygous mutations in patients with overlapping phenotypes. In addition, exome sequencing revealed de novo and recessive variants in 32 genes (MAMDC2, TUBAL3, CPNE6, KLHL24, USP2, PIP5K1A, UBE4A, TP53TG5, ATOH1, C16ORF90, SLC39A14, TRERF1, RGL1, CDH11, SYDE2, HIRA, FEZF2, PROCA1, PIANP, PLK2, QRFPR, AP3B2, NUDT2, UFC1, BTN3A2, TADA1, ARFGEF3, FAM160B1, ZMYM5, SLC45A1, ARHGAP33 and CAPS2), which we highlight as potential candidates on the basis of several lines of evidence, and one of these genes (SLC39A14) was biallelically inactivated in a potentially treatable form of hypermanganesemia and neurodegeneration. Finally, likely causal variants in previously published candidate genes were identified (ASTN1, HELZ, THOC6, WDR45B, ADRA2B and CLIP1), thus supporting their involvement in ID pathogenesis. Our results expand the morbid genome of ID and support the adoption of genomics as a first-tier test for individuals with ID.

Abstract
This study was designed to perform biological and molecular characterization of avian adenoviruses (AAVs) recovered from suspected cases of hydropericardium-hepatitis syndrome (HHS) in commercial poultry. Initially the samples were screened by Agar Gel Precipitation Test (AGPT) for the presence of AAVs followed by its confirmation and typing through polymerase chain reaction (PCR) focusing on already reported serotypes AAV-4, AAV-8 and AAV-10 elsewhere. These PCR-positive samples were further subjected to amplification of fiber gene, followed by conducting restriction fragment length polymorphism (RFLP) using restriction enzyme Alu. The selected isolates were further propagated through cell culture and pathogenic potential of selected isolates was determined by infecting chickens. In this study, out of a total 190 samples, 57.8% of suspected cases were found positive for AAV presence through AGPT while sub-type identification using PCR revealed 46.3% for these viruses belonging to AAV-4, 41.8% to AAV-8 and 11.8% showed co-infection of AAV-4 and AAV-8. AAV-10 was not detected in any of the tested samples. On the basis of RFLP pattern, AAV-4 isolates were further divided into four sub-groups (A-D) while AAV-8 isolates had identical RFLP pattern. To further evaluate the pathogenic potential of these sub-groups of AAV-4 isolates, specific pathogen free (SPF) chicks were challenged with selected isolates belonging to each of the sub-groups, resulting in variable pattern of pathogenicity. It is concluded that any variation in the fiber gene of AAV-4 isolates may affect its pathogenicity and eventually specificity of the vaccines used against such infections. Therefore, regular monitoring of the circulating AAV serotypes may be helpful in understanding the pathogenic potential of emerging AAVs, which may lead to development of more effective response strategies accordingly.

Abstract
Outcome of children with nephrotic syndrome has continued to improve over time. However minimal data exist to describe health-related quality of life in children with nephrotic syndrome. This cross sectional study was conducted over a period of six months to assess the health related quality of life in children with nephrotic syndrome in the Department of Pediatric Nephrology, Dhaka Medical College Hospital, Bangladesh. Fifty children (age ranged 2-12 years) with nephrotic syndrome who had three or more relapses diagnosed at least one year back receiving treatment and on follow up were included in this study. Quality of Life scores were collected using Bengali translated instruments- the Pediatric Quality of Life Inventory™ (PedsQL™) version 4.0 Generic Scale and the Pediatric Quality of Life Questionnaire for Nephrotic Syndrome proxy-report from parents. Medical data and Demographic data were collected from medical records, and from parents in outpatient department or hospital ward. Interviews of eligible guardians were performed individually to collect quality of life (QoL) scores. Among 50 children, mean±SD age of the children was 7±2.92 years. Most children were male (58%). Female parents respondent during interview were 62%, most parents (48%) were very poor in socioeconomic condition. Most children had frequent relapses (60%). Median time since diagnosis was 2 years. Regarding PedsQL scores, child age with physical summary score (p value <0.001), child age with social summary score (p value 0.003), frequent relapse with kidney disease summary score (p value 0.04) and time since diagnosis (p value <0.001) were statistically significant. In conclusion physical and social summary score were worst. Frequent relapse found to be an important factor in impaired QoL. Prolonged duration of the disease activity was associated with significant impairment of QoL.

Abstract
The role of the nitric oxide(NO) radicalin systemic lupus erythematosus(SLE) pathogenesishas been investigated in the present study. The binding characteristics of SLE autoantibodies with native calf thymus DNA, native and NO-modified plasmid DNA were assessed. Binding characteristics and specificity of antibodies were analysed by direct binding and inhibition ELISA, gel retardation assay and quantitativeprecipitin titration.The data shows preferentialbinding of SLE autoantibodiesto NO-modified plasmid DNA (NO-DNA) in comparison with native plasmid DNA. Inhibition ELISA reiterates the direct binding results. Gel retardation assay further substantiated the enhanced recognition of NO-DNA by anti-DNA autoantibodies. The binding affinity of modified and native plasmid DNA with one of the SLE IgGs was calculated, using the Langmuir plot. The apparent association constant for NO-plasmid DNA was found to be highest, followed by native calf thymus DNA and native plasmid DNA. The results suggest that the NO radical modification of plasmid DNA causes perturbations, resulting in the generation of neo-epitopes, and making it a potential immunogen. The DNA modified with the NO radical may be one of the factors for the induction of circulating SLE anti-DNA autoantibodies.

Naringenin is a naturally occurring flavanones and has been found to exhibit free radical scavenging, enzyme inhibition, antioxidants, anti-inflammatory, and anticancer activities. Present study was designed to evaluate the protective role of naringenin against benzo[a]pyrene (B[a]P)-induced oxidative stress and pulmonary toxicity. Rats were treated with naringenin at a dose of 100 mg/kg body weight (b. wt.), by oral gavage. B[a]P in a single dose of 50 mg/kg b. wt. was given intraperitoneally. Total protein, total cell counts, lactate dehydrogenase, lipid peroxidation, reduced glutathione, antioxidant enzymes activities, lung histology and expression of nuclear factor kappa B (NF-κB), and cyclo-oxygenase-2 (COX-2) was assessed to evaluate protective effects of naringenin. Histopathological and immunohistochemical studies were also carried out to observe lung toxicity and inflammation. B[a]P administration enhanced the levels of lung injury markers and reduced antioxidant enzymes activities. Naringenin treatment attenuated the levels of oxidative stress by restoring antioxidant enzymes, further improved lung histological damage and significant decrease in inflammatory responses. Naringenin also effectively decreased the expression of NF-κB, and COX-2 induced by B[a]P. These findings suggest that naringenin supplementation is beneficial in maintaining the integrity of alveoli and the epithelium that may be used as a protective agent in B[a]P-induced oxidative stress and lung damage. However, further studies are warranted to elucidate the potential mechanism of action of naringenin.

Abstract
Conventional catheter-based systems used for ambulatory esophageal pH monitoring have been reported to affect patient behavior. As physical activity has been associated with gastroesophageal reflux disease (GERD), there is a risk that abnormal behavior will degrade the value of this diagnostic investigation and consequent management strategies. The aim of this study was to quantify the effect of conventional pH monitoring on behavior and to investigate the temporal association between activity and reflux. A total of 20 patients listed for 24 hours pH monitoring underwent activity monitoring using a lightweight ear-worn accelerometer (e-AR sensor, Imperial College London) 2 days prior to, and during their investigation. PH was measured and recorded using a conventional nasogastric catheter and waist-worn receiver. Daily activity levels, including subject-specific activity intensity quartiles, were calculated and compared. Physical activity was added to the standard pH output to supplement interpretation. Average patient activity levels decreased by 26.5% during pH monitoring (range -4.5 to 51.0%, P = 0.036). High-intensity activity decreased by 24.4% (range -4.0 to 75.6%, P = 0.036), and restful activity increased on average by 34% although this failed to reach statistical significance (-24.0 to 289.2%, P = 0.161). Some patients exhibited consistent associations between bouts of activity and acidic episodes. The results of this study support the previously reported reduction in activity during ambulatory esophageal pH monitoring, with the added reliability of objective data. In the absence of more pervasive pH monitoring systems (e.g. wireless), quantifying activity changes in the setting of activity-induced reflux might guide the physicians' interpretation of patient DeMeester scores resulting in more appropriate management of GERD.

Abstract
Intron retention in transcripts and the presence of 5' and 3' splice sites within these introns mediate alternate splicing, which is widely observed in animals and plants. Here, functional characterisation of the K(+) transporter, HvHKT2;1, with stably retained introns from barley (Hordeum vulgare) in yeast (Saccharomyces cerevisiae), and transcript profiling in yeast and transgenic tobacco (Nicotiana tabacum) is presented. Expression of intron-retaining HvHKT2;1 cDNA (HvHKT2;1-i) in trk1, trk2 yeast strain defective in K(+) uptake restored growth in medium containing hygromycin in the presence of different concentrations of K(+) and mediated hypersensitivity to Na(+) . HvHKT2;1-i produces multiple transcripts via alternate splicing of two regular introns and three exons in different compositions. HKT isoforms with retained introns and exon skipping variants were detected in relative expression analysis of (i) HvHKT2;1-i in barley under native conditions, (ii) in transgenic tobacco plants constitutively expressing HvHKT2;1-i, and (iii) in trk1, trk2 yeast expressing HvHKT2;1-i under control of an inducible promoter. Mixed proportions of three HKT transcripts: HvHKT2;1-e (first exon region), HvHKT2;1-i1 (first intron) and HvHKT2;1-i2 (second intron) were observed. The variation in transcript accumulation in response to changing K(+) and Na(+) concentrations was observed in both heterologous and plant systems. These findings suggest a link between intron-retaining transcripts and different splice variants to ion homeostasis, and their possible role in salt stress.

Abstract
Several β cell antigens recognized by T cells in the non-obese diabetic (NOD) mouse model of type 1 diabetes (T1D) are also T cell targets in the human disease. While numerous antigen-specific therapies prevent diabetes in NOD mice, successful translation of rodent findings to patients has been difficult. A human leucocyte antigen (HLA)-transgenic mouse model incorporating human β cell-specific T cells might provide a better platform for evaluating antigen-specific therapies. The ability to study such T cells is limited by their low frequency in peripheral blood and the difficulty in obtaining islet-infiltrating T cells from patients. We have worked to overcome this limitation by using lentiviral transduction to 'reprogram' primary human CD8 T cells to express three T cell receptors (TCRs) specific for a peptide derived from the β cell antigen islet-specific glucose-6-phosphatase catalytic subunit-related protein (IGRP265-273 ) and recognized in the context of the human class I major histocompatibility complex (MHC) molecule HLA-A2. The TCRs bound peptide/MHC multimers with a range of avidities, but all bound with at least 10-fold lower avidity than the anti-viral TCR used for comparison. One exhibited antigenic recognition promiscuity. The β cell-specific human CD8 T cells generated by lentiviral transduction with one of the TCRs released interferon (IFN)-γ in response to antigen and exhibited cytotoxic activity against peptide-pulsed target cells. The cells engrafted in HLA-A2-transgenic NOD-scid IL2rγ(null) mice and could be detected in the blood, spleen and pancreas up to 5 weeks post-transfer, suggesting the utility of this approach for the evaluation of T cell-modulatory therapies for T1D and other T cell-mediated autoimmune diseases.

Abstract
INTRODUCTION In 2013 the Department of Health specified eligibility for bariatric surgery funded by the National Health Service. This included a mandatory specification that patients first complete a Tier 3 medical weight management programme. The clinical effectiveness of this recommendation has not been evaluated previously. Our bariatric centre has provided a Tier 3 programme six months prior to bariatric surgery since 2009. The aim of our retrospective study was to compare weight loss in two cohorts: Roux-en-Y gastric bypass only (RYGB only cohort) versus Tier 3 weight management followed by RYGB (Tier 3 cohort). METHODS A total of 110 patients were selected for the study: 66 in the RYGB only cohort and 44 in the Tier 3 cohort. Patients in both cohorts were matched for age, sex, preoperative body mass index and pre-existing co-morbidities. The principal variable was therefore whether they undertook the weight management programme prior to RYGB. Patients from both cohorts were followed up at 6 and 12 months to assess weight loss. RESULTS The mean weight loss at 6 months for the Tier 3 cohort was 31% (range: 18-69%, standard deviation [SD]: 0.10 percentage points) compared with 23% (range: 4-93%, SD: 0.12 percentage points) for the RYGB only cohort (p=0.0002). The mean weight loss at 12 months for the Tier 3 cohort was 34% (range: 17-51%, SD: 0.09 percentage points) compared with 27% (range: 14-48%, SD: 0.87 percentage points) in the RYGB only cohort (p=0.0037). CONCLUSIONS Our study revealed that in our matched cohorts, patients receiving Tier 3 specialist medical weight management input prior to RYGB lost significantly more weight at 6 and 12 months than RYGB only patients. This confirms the clinical efficacy of such a weight management programme prior to gastric bypass surgery and supports its inclusion in eligibility criteria for bariatric surgery.

Abstract
The use of day case surgery is on the rise. In order to improve efficiency and reduce cost, it has been proposed that tonsillectomy could be undertaken as a day-case procedure in Ireland. A retrospective, chart-based study was carried out. The medical and social criteria of all patients who underwent tonsillectomy during a twelve-month period were evaluated. Individual, local and national factors were identified and international comparisons were made. Of 161 patients included, 43 (27%) were considered suitable for day case tonsillectomy (DCT). The distance/time criteria from hospital excluded 64% of patients. The diagnosis of obstructive sleep apnoea was the single most common medical reason for exclusion. Support structures were deficient. Local factors must be considered before any policy or targets are developed for DCT. Patient safety is the fundamental tenet. Currently, the infrastructure and the support required for a patient-focused, safe efficient DCT are deficient, and need investment.

Abstract
Many alternative tobacco products (ATPs), such as hookahs, have grown in popularity and use beyond their locale of origin and are therefore becoming a significant global public health concern. This article provides an overview of an under-reported and understudied ATP, dokha, which is smoked in a midwakh pipe. It describes the state of tobacco control in the Arabian Gulf region where midwakh smoking appears to be most common, the history of midwakh and dokha use, and what is known about midwakh smoking from the published literature. On the basis of the stark lack of data on midwakh use, we suggest priority areas to focus future research. Preliminary data and observations from health providers and the public health sector suggest that midwakh smoking may pose challenges to the tobacco control efforts in the Arabian Gulf region. If it is emerging as a new ATP outside this region, there could be a significant impact on tobacco control strategies globally.

Abstract
The objective of this novel catalyst development is to achieve both low temperature and high conversion of sour gases. Supported mixed metal oxide catalysts were prepared by impregnating the catalysts on alumina beads for the in-situ reactions of H2S desulfurization and CO2 methanation from room temperature up to 200oC. The results showed that the 100% conversion of H2S to elemental sulfur for all of the potential catalysts was achieved at 100oC. However, methanation of CO2 in the presence of H2S yielded 0.4% CH4 over Fe/Zn/Cu/Ti-Al2O3 catalyst and 0.7% CH4 over Fe/Zn/Cu-Al2O3 catalyst at maximum studied temperature of 200oC. XPS results indicated that spinel compounds of CuFe2O4 and Fe3O4 act as the active sites on the Fe/Zn/Cu-Al2O3 and Fe/Zn/Cu/Ti-Al2O3 catalysts. The appearance of Fe3+-OH on Fe/Zn/Cu/Ti-Al2O3 catalyst increased its H2S desulfurization activity. N2 adsorption-desorption analysis illustrated that 34% of the surface area of Fe/Zn/Cu-Al2O3 catalyst was reduced while Fe/Zn/Cu/Ti-Al2O3 catalyst showedreduction of 17% after catalytic testing, which indicated the deactivation of the catalysts resulted from sulfur poisoning.

Abstract
BACKGROUND Thyroid cancer incidence is increasing worldwide, but with large variations in incidence that may reflect either diagnostic bias or true ethnic differences. We sought to determine the effect of ethnicity on the incidence of thyroid cancer in England, a multiethnic population with a single health-care system. METHODS We analysed 11,263 thyroid cancer registrations with ethnicity obtained by linkage to the Hospital Episodes Statistics database. Incidence rate ratios (RRs) adjusted for age, sex and income were calculated for the six main non-White ethnic groups in England compared with Whites and to each other. RESULTS Thyroid cancer incidence was higher in all ethnic groups, except Indians, compared with Whites: in Pakistanis (RR 1.79, 99% floating confidence interval (FCI) 1.47-2.19); Bangladeshis (RR 1.99, 99% FCI 1.46-2.71); Black Africans (RR 1.69, 99% FCI 1.34-2.13); Black Caribbeans (RR 1.56, 99% FCI 1.25-1.93); and Chinese (RR 2.14, 99% FCI 1.63-2.80). CONCLUSION The risk of thyroid cancer in England varies significantly by ethnicity. The elevated incidence in most ethnic minorities is unlikely to be due to diagnostic bias and warrants further investigation.

Abstract
BACKGROUND In the United Kingdom, breast cancer incidence is lower in South Asian and Black women than in White women, but the extent to which this is due to known risk factors is unknown. In a large prospective study, we describe breast cancer incidence by ethnicity, before and after adjustment for known risk factors for the disease. METHODS Women were recruited into the Million Women Study in 1996-2001, when information on reproductive and lifestyle factors known to influence the risk of breast cancer was obtained. Ethnicity was determined from study questionnaires and hospital admission data. Cox regression models were used to calculate adjusted relative risks (RR) for incident breast cancer in South Asians and Blacks compared with Whites. RESULTS Analyses included 5877 South Asian, 4919 Black, and 1,038,144 White women in England. The prevalence of 8 out of the 9 risk factors for breast cancer examined, differed substantially by ethnicity (P<0.001 for each), such that South Asian and Black women were at a lower risk of the disease than White women. During 12.2 years of follow-up incident breast cancer occurred in 217 South Asians, 180 Blacks, and 45,191 Whites. As expected, breast cancer incidence was lower in South Asians (RR=0.82, 95% CI 0.72-0.94) and Blacks (RR=0.85, 0.73-0.98) than in Whites when the analyses were adjusted only for age and region of residence. However, after additional adjustment for the known risk factors for the disease, breast cancer incidence was similar to that of Whites, both in South Asians (0.95, 0.83-1.09) and in Blacks (0.91, 0.78-1.05). CONCLUSION South Asian and Black women in England have lower incidence rates of breast cancer than White women, but this is largely, if not wholly, because of differences in known risk factors for the disease.

Abstract
Whole exome sequencing (WES) has greatly facilitated the identification of causal mutations for diverse human genetic disorders. We applied WES as a molecular diagnostic tool to identify disease-causing genes in consanguineous families in Qatar. Seventeen consanguineous families with diverse disorders were recruited. Initial mutation screening of known genes related to the clinical diagnoses did not reveal the causative mutations. Using WES approach, we identified the definitive disease-causing mutations in four families: (i) a novel nonsense homozygous (c.1034C>G) in PHKG2 causing glycogen storage disease type 9C (GSD9C) in a male with initial diagnosis of GSD3; (ii) a novel homozygous 1-bp deletion (c.915del) in NSUN2 in a male proband with Noonan-like syndrome; (iii) a homozygous SNV (c.1598C>G) in exon 11 of IDUA causing Hurler syndrome in a female proband with unknown clinical diagnosis; (iv) a de novo known splicing mutation (c.1645+1G>A) in PHEX in a female proband with initial diagnosis of autosomal recessive hypophosphatemic rickets. Applying WES as a diagnostic tool led to the unambiguous identification of disease-causing mutations in phenotypically complex disorders or correction of the initial clinical diagnosis in ˜25% of our cases.

Abstract
Hypoxia-specific cytotoxins have long exhibited considerable promise for treating hypoxic tumors, however recent negative results in large scale clinical trials have highlighted the importance of selecting patients who are most likely to respond using hypoxia imaging methods. This review looks at the available hypoxia-specific cytotoxins and describes how existing hypoxia imaging methods can be best used to predict which tumors will respond. It then surveys prior studies which combine hypoxia-selective cytotoxin treatment with hypoxia imaging, and finally concludes with a discussion of what lessons can be learnt from previous experiences in order to improve the use of these cytotoxic agents in future clinical evaluations.

Abstract
Embryonic neural tumors are responsible for a disproportionate number of cancer deaths in children. Although dramatic improvements in survival for pediatric malignancy has been achieved in previous years advancements seem to be slowing down. For the development of new enhanced therapy and an increased understanding of the disease, pre-clinical models better capturing the neoplastic niche are essential. Tumors of early childhood present in this respect a particular challenge. Here, we explore how components of the embryonic process in stem‑cell induced mature teratoma can function as an experimental in vivo microenvironment instigating the growth of injected childhood neuroblastoma (NB) cell lines. Three human NB cell lines, IMR-32, Kelly and SK-N-BE(2), were injected into mature pluripotent stem cell‑induced teratoma (PSCT) and compared to xenografts of the same cell lines. Proliferative NB cells from all lines were readily detected in both models with a typical histology of a poorly differentiated NB tumor with a variable amount of fibrovascular stroma. Uniquely in the PSCT microenvironment, NB cells were found integrated in a non‑random fashion. Neuroblastoma cells were never observed in areas with well-differentiated somatic tissue i.e. bone, muscle, gut or areas of other easily identifiable tissue types. Instead, the three cell lines all showed initial growth exclusively occurring in the embryonic loose mesenchymal stroma, resulting in a histology recapitulating NB native presentation in vivo. Whether this reflects the 'open' nature of loose mesenchyme more easily giving space to new cells compared to other more dense tissues, the rigidity of matrix providing physical cues modulating NB characteristics, or if embryonic loose mesenchyme may supply developmental cues that attracted or promoted the integration of NB, remains to be tested. We tentatively hypothesize that mature PSCT provide an embryonic niche well suited for in vivo studies on NB.

Abstract
Yersinia pestis is a facultative bacterium that can survive and proliferate inside host macrophages and cause bubonic, pneumonic and systemic infection. Apart from humoral response, cell-mediated protection plays a major role in combating the disease. Fraction 1 capsular antigen (F1-Ag) of Y. pestis has long been exploited as a vaccine candidate. In this study, F1-multiple antigenic peptide (F1-MAP or MAP)-specific cell-mediated and cytokine responses were studied in murine model. MAP consisting of three B and one T cell epitopes of F1-antigen with one palmitoyl residue was synthesized using Fmoc chemistry. Mice were immunized with different formulations of MAP in poly DL-lactide-co-glycolide (PLGA) microspheres. F1-MAP with CpG oligodeoxynucleotide (CpG-ODN) as an adjuvant showed enhanced in vitro T cell proliferation and Th1 (IL-2, IFN-γ and TNF-α) and Th17 (IL-17A) cytokine secretion. Similar formulation also showed significantly higher numbers of cytokine (IL-2, IFN-γ)-secreting cells. Moreover, F1-MAP with CpG formulation showed significantly high (P < 0.001) percentage of CD4(+) IFN-γ(+) cells as compared to CD8(+) IFN-γ(+) cells, and also more (CD4- IFN-γ)(+) cells secrete perforin and granzyme as compared to (CD8- IFN-γ)(+) showing Th1 response. Thus, the study highlights the importance of Th1 cytokine and existence of CD4(+) and CD8(+) immune response. This study proposes a new perspective for the development of vaccination strategies for Y. pestis that trigger T cell immune response.
