Abstract
Neural correlates of intentionally induced human emotions may offer alternative imagery strategies to control brain-computer interface (BCI) applications. In this paper, a novel BCI control strategy i.e., imagining fictional or recalling mnemonic sad and happy events, emotion-inducing imagery (EII), is compared to motor imagery (MI) in a study involving multiple sessions using a two-class electroencephalogram (EEG)-based BCI paradigm with 12 participants. The BCI setup enabled online continuous visual feedback presentation in a game involving one-dimensional control of a game character. MI and EII are compared across different signal-processing frameworks which are based on neural-time-series-prediction-preprocessing (NTSPP), filter bank common spatial patterns (FBCSP) and hemispheric asymmetry (ASYM). Online single-trial classification accuracies (CA) results indicate that MI performance across all participants is 77.54% compared to EII performance of 68.78% ( ). The results show that an ensemble of the NTSPP, FBCSP and ASYM frameworks maximizes performance for EII with average CA of 71.64% across all participants. Furthermore, the participants' subjective responses indicate that they preferred MI over emotion-inducing imagery (EII) in controlling the game character, and MI was perceived to offer most control over the game character. The results suggest that EII is not a viable alternative to MI for the majority of participants in this study but may be an alternative imagery for a subset of BCI users based on acceptable EII performance (CA >70%) observed for some participants.

Abstract
SUMMARY We present three cases of acute diabetic neuropathy and highlight a potentially underappreciated link between tightening of glycaemic control and acute neuropathies in patients with diabetes. Case 1: A 56-year-old male with poorly controlled type 2 diabetes (T2DM) was commenced on basal-bolus insulin. He presented 6 weeks later with a diffuse painful sensory neuropathy and postural hypotension. He was diagnosed with treatment-induced neuropathy (TIN, insulin neuritis) and obtained symptomatic relief from pregabalin. Case 2: A 67-year-old male with T2DM and chronic hyperglycaemia presented with left lower limb pain, weakness and weight loss shortly after achieving target glycaemia with oral anti-hyperglycaemics. Neurological examination and neuro-electrophysiological studies suggested diabetic lumbosacral radiculo-plexus neuropathy (DLPRN, diabetic amyotrophy). Pain and weakness resolved over time. Case 3: A 58-year-old male was admitted with blurred vision diplopia and complete ptosis of the right eye, with intact pupillary reflexes, shortly after intensification of glucose-lowering treatment with an SGLT2 inhibitor as adjunct to metformin. He was diagnosed with a pupil-sparing third nerve palsy secondary to diabetic mononeuritis which improved over time. While all three acute neuropathies have been previously well described, all are rare and require a high index of clinical suspicion as they are essentially a diagnosis of exclusion. Interestingly, all three of our cases are linked by the development of acute neuropathy following a significant improvement in glycaemic control. This phenomenon is well described in TIN, but not previously highlighted in other acute neuropathies. LEARNING POINTS A link between acute tightening of glycaemic control and acute neuropathies has not been well described in literature. Clinicians caring for patients with diabetes who develop otherwise unexplained neurologic symptoms following a tightening of glycaemic control should consider the possibility of an acute diabetic neuropathy. Early recognition of these neuropathies can obviate the need for detailed and expensive investigations and allow for early institution of appropriate pain-relieving medications.

Abstract
Three dimensional (3D) limb motion trajectory is predictable with a non-invasive brain-computer interface (BCI). To date, most non-invasive motion trajectory prediction BCIs use potential values of electroencephalographic (EEG) signals as the input to a multiple linear regression (mLR) based kinetic data estimator. We investigated the possible improvement in accuracy of 3D hand movement prediction (i.e., the correlation of registered and reconstructed hand velocities) by replacing raw EEG potentials with spectrum power values of specific EEG bands. We also investigated if a non-linear neural network based estimator outperformed the mLR approach. The spectrum power model provided significantly higher accuracy (R~0.60) compared to the similar EEG potentials based approach (R~0.45). Additionally, when replacing the mLR based kinetic data estimation module with a feed-forward neural network (NN) we found the NN based spectrum power model provided higher accuracy (R~0.70) compared to the similar mLR based approach (R~0.60).

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
A motion trajectory prediction (MTP) - based brain-computer interface (BCI) aims to reconstruct the three-dimensional (3D) trajectory of upper limb movement using electroencephalography (EEG). The most common MTP BCI employs a time series of bandpass-filtered EEG potentials (referred to here as the potential time-series, PTS, model) for reconstructing the trajectory of a 3D limb movement using multiple linear regression. These studies report the best accuracy when a 0.5-2Hz bandpass filter is applied to the EEG. In the present study, we show that spatiotemporal power distribution of theta (4-8Hz), mu (8-12Hz), and beta (12-28Hz) bands are more robust for movement trajectory decoding when the standard PTS approach is replaced with time-varying bandpower values of a specified EEG band, ie, with a bandpower time-series (BTS) model. A comprehensive analysis comprising of three subjects performing pointing movements with the dominant right arm toward six targets is presented. Our results show that the BTS model produces significantly higher MTP accuracy (R~0.45) compared to the standard PTS model (R~0.2). In the case of the BTS model, the highest accuracy was achieved across the three subjects typically in the mu (8-12Hz) and low-beta (12-18Hz) bands. Additionally, we highlight a limitation of the commonly used PTS model and illustrate how this model may be suboptimal for decoding motion trajectory relevant information. Although our results, showing that the mu and beta bands are prominent for MTP, are not in line with other MTP studies, they are consistent with the extensive literature on classical multiclass sensorimotor rhythm-based BCI studies (classification of limbs as opposed to motion trajectory prediction), which report the best accuracy of imagined limb movement classification using power values of mu and beta frequency bands. The methods proposed here provide a positive step toward noninvasive decoding of imagined 3D hand movements for movement-free BCIs.

Abstract
BACKGROUND 5-Amino salicylate (5-ASA) medications may rarely be associated with a significant decline in renal function and interstitial nephritis. British Society of Gastroenterology guidelines advise regular renal function monitoring for patients taking these drugs. AIM To assess whether gastroenterologists in Kent were following best practice guidelines regarding the monitoring of their patients on 5-ASA therapy. METHODS Using longitudinal community and regional pathology databases for the Kent population, our renal unit regularly screens a total population of 300 000 for evidence of renal disease. The data extracted are analysed using an automated computerised system to identify patients requiring intervention for kidney disease. All patients taking 5-ASA medication were identified from a population of 300 000. The pathology database was studied to identify the patients on 5-ASA treatment and whether they had had renal function tests. RESULTS 800 adult patients were identified taking 5-ASA therapy. 612 patients received 5-ASAs for 3 months or more, and these were included in the final analysis. 293 patients had no renal function checks while on treatment. 79 patients had renal function tests less than once every 4 years and 36 patients once every 2-4 years. 204 patients had renal function measurements in 50% or more of years of treatment, of whom 116 were checked every year. Some patients were started on treatment with abnormal results at baseline and some with identified kidney disease continued on their 5-ASAs. CONCLUSIONS The majority of patients receiving 5-ASA compounds do not have regular renal function monitoring. Clinicians are failing to follow best practice guidelines.

Abstract
During routine avian influenza surveillance in Pakistan, a low-pathogenic avian influenza virus (LPAI) subtype H3N1 was isolated for the first time from domestic chickens. The higher seroprevalence of H3N1 was recorded in both commercial and domestic poultry in ecological zones of Pakistan where the geographical proximity with neighboring countries and attractive birding sites provide better opportunities for frequent movements of wild and migratory birds, and their intermingling with the local domestic and commercial poultry. Subsequent whole genome sequencing of this virus revealed a new introduction of a reassortant Eurasian avian strain, which was distinguishable from corresponding human and swine strains isolated elsewhere. Phylogenetically, the HA gene was mostly clustered with Nordic (Scandinavian) strains of influenza viruses, whereas the NA and PB1 genes showed a maximum nucleotide sequence homology with the Indian H11N1, and the PB2 gene was found to be closely related to the Altai H5N2. The Matrix and NP genes of H3N1 mostly clustered with the European avian influenza viruses (AIV), whereas its NS and PA genes showed maximum nucleotide homologies with the African (Egypt) AIV strains. A sequence and amino acid analysis revealed an LP motif, avian-like receptor specificity, potential glycosylation sites, and sensitivities to oseltamivir, zanamivir, and amantadine. Some point mutations possessed by this Pakistani AIV H3N1 were also found in human, equine, and swine H3 influenza viruses. This H3N1 isolate showed less nucleotide sequence homology with the previously known Pakistani AIV as compared with other Eurasian AIV strains.

Abstract
OBJECTIVE Amyotrophic lateral sclerosis (ALS) is a progressive paralytic disorder caused by degeneration of motor neurons. Mutations in the FUS gene were identified in patients with familial ALS (FALS) and patients with sporadic ALS (SALS) from a variety of genetic backgrounds. This work further explores the spectrum of FUS mutations in patients with FALS and patients with FALS with features of frontotemporal dementia (FALS/FTD) or parkinsonism and dementia (FALS/PD/DE). METHODS All exons of the FUS gene were sequenced in 476 FALS index cases negative for mutations in SOD1 and TARDBP. A total of 561-726 controls were analyzed for genetic variants observed. Clinical data from patients with FUS mutations were compared to those of patients with known SOD1 and TARDBP mutations. RESULTS We identified 17 FUS mutations in 22 FALS families, 2 FALS/FTD families, and 1 FALS/PD/DE family from diverse genetic backgrounds; 11 mutations were novel. There were 4 frameshift, 1 nonsense, and 1 possible alternate splicing mutation. Patients with FUS mutations appeared to have earlier symptom onset, a higher rate of bulbar onset, and shorter duration of symptoms than those with SOD1 mutations. CONCLUSIONS FUS gene mutations are not an uncommon cause in patients with FALS from diverse genetic backgrounds, and have a prevalence of 5.6% in non-SOD1 and non-TARDBP FALS, and approximately 4.79% in all FALS. The pathogenicity of some of these novel mutations awaits further studies. Patients with FUS mutations manifest earlier symptom onset, a higher rate of bulbar onset, and shorter duration of symptoms.

Abstract
Five nuts, namely almond, cashew nuts, peanuts, pine nuts and pistachio, commonly consumed in Pakistan, were analyzed for their inorganic element contents. Instrumental neutron activation analysis (INAA) methodology, using different irradiation, cooling and counting protocols, was adopted to determine Al, Br, Ca, Cl, Co, Cs, Eu, Fe, Hg, K, La, Mg, Mn, Mo, Na, Rb, Sc, Se, Sr and Zn. The investigated nuts were found to contain substantial amounts of Ca, Cl, Fe, Mg, K, Na and Zn. Dietary intake of the essential inorganic elements present in these nuts, as compared to the recommended dietary allowance, has also been calculated. This has further substantiated the nutrient role of nuts in the prevention of cardiovascular disease, as in addition to their established efficacy in improving the lipid profile, they are a rich source of cardioprotective trace elements such as magnesium, zinc, iron and calcium. Toxic elements were present in very low concentrations in nuts.

Abstract
BACKGROUND The alanine to valine mutation at codon 4 (A4V) of SOD1 causes a rapidly progressive dominant form of amyotrophic lateral sclerosis (ALS) with exclusively lower motor neuron disease and is responsible for 50% of SOD1 mutations associated with familial ALS in North America. This mutation is rare in Europe. The authors investigated the origin (geographic and time) of the A4V mutation. METHODS Several cohorts were genotyped: North American patients with confirmed A4V mutation (n = 54), Swedish (n = 3) and Italian (n = 6) A4V patients, patients with ALS with SOD1 non-A4V mutations (n = 66) and patients with sporadic ALS (n = 96), healthy white (n = 96), African American (n = 17), Chinese (n = 53), Amerindian (n = 11), and Hispanic (n = 12) subjects. High-throughput SNP genotyping was performed using Taqman assay in 384-well format. A novel biallelic CA repeat in exon 5 of SOD1, tightly linked to A4V, was genotyped on sequencing gels. Association statistics were estimated using Haploview. p Values less than 0.05 were considered significant. Age of A4V was estimated using a novel method based on r(2) degeneration with genetic distance and a Bayesian method incorporated in DMLE+. RESULTS A single haplotype of 10 polymorphisms across a 5.86-cM region was associated with A4V (p = 3.0e-11) when white controls were used, suggesting a founder effect. The strength of association of this haplotype progressively decreased when African American, Chinese, Hispanic, and Amerindian subjects were used as controls. The associated European haplotype was different from the North American haplotype, indicating two founder effects for A4V (Amerindian and European). The estimated age of A4V with the r(2) degeneration method was 458 +/- 59 years (range 398-569) and in agreement with the Bayesian method (554-734 years with 80-90% posterior probability). CONCLUSIONS North American SOD1 alanine to valine mutation at codon 4 descended from two founders (Amerindian and European) 400-500 years ago.

Abstract
This guidance for the management of patients with allergic and non‐allergic rhinitis has been prepared by the Standards of Care Committee (SOCC) of the British Society for Allergy and Clinical Immunology (BSACI). The guideline is based on evidence as well as on expert opinion and is for use by both adult physicians and paediatricians practicing in allergy. The recommendations are evidence graded. During the development of these guidelines, all BSACI members were included in the consultation process using a web‐based system. Their comments and suggestions were carefully considered by the SOCC. Where evidence was lacking, consensus was reached by the experts on the committee. Included in this guideline are clinical classification of rhinitis, aetiology, diagnosis, investigations and management including subcutaneous and sublingual immunotherapy. There are also special sections for children, co‐morbid associations and pregnancy. Finally, we have made recommendations for potential areas of future research.

Abstract
From November 2003 to June 2004 an epidemic of high pathogenicity avian influenza (HPAI) virus of subtype H7N3 affected the major layer and broiler-breeder raising areas of the country. This was accompanied by an outbreak of low pathogenicity avian influenza (LPAI) virus of type H9N2 in broilers and layers, which continued during 2005. Subsequently, in February 2006 avian influenza virus (AIV) subtype H5N1 was for the first time found in two isolated commercial flocks in this country. The HPAI outbreak of 2003-2004 was eventually overcome by enforcing biosecurity measures, controlling poultry movements, using inactivated vaccines, and introducing a comprehensive AI surveillance network throughout the country. However, similar measures undertaken to control H9N2 outbreaks have not been successful in the affected areas, with continuing increased mortality and heavy production losses in broilers and layers, respectively. A similar strategy has been devised to combat the spread of newly introduced H5N1 HPAIV. The description of these outbreaks and the results of the control strategy are reported here.

Abstract
The authors tested the association of three vascular endothelial growth factor (VEGF) promoter polymorphisms with sporadic ALS (SALS) to verify the results of a previous study and to investigate their modifier effects on the subphenotypes of SALS in a large family-based and case-control cohort of North American white subjects (N = 1,603). They did not find any association of the VEGF promoter polymorphisms with SALS or its subphenotypes, suggesting that they do not have a direct causal role in ALS.

Abstract
BACKGROUND Paraoxonases (PONs) are involved in the detoxification of organophosphate pesticides and chemical nerve agents. Due to a reported possible twofold increased risk of ALS in Gulf War veterans and the associations of PON1 polymorphisms with the neurologic symptom complex of the Gulf War syndrome, the authors investigated the association between sporadic ALS (SALS) and PON gene cluster variants in a large North American Caucasian family-based and case-control cohort (N = 1,891). METHODS Clinically definite and probable ALS was diagnosed according to the revised El Escorial criteria, exclusion of family history of ALS, and SOD1 mutation analysis. Single nucleotide polymorphism (SNP) genotyping was done using TaqMan assays on ABI7900HT. Data were analyzed using SPSS, Haploview, FBAT, and THESIAS. RESULTS A haploblock of high linkage disequilibrium (LD) spanning PON2 and PON3 was associated with SALS. The SNPs rs10487132 and rs11981433 were in strong LD and associated with SALS in the trio (parents-affected child triad) model. The association of rs10487132 was replicated in 450 nuclear pedigrees comprising trios and discordant sibpairs. No association was found in case-control models, and their haplostructure was different from that of the trios with overall reduced LD. Resequencing identified an intronic variant (rs17876088) that differentiated between detrimental and protective SALS haplotypes. CONCLUSION This study demonstrates evidence of significant association of variants in the Paraoxonase gene cluster with sporadic ALS and is compatible with the hypothesis that environmental toxicity in a susceptible host may precipitate ALS.

Abstract
The first outbreak of highly pathogenic avian influenza (HPAI) virus caused by subtype H7N3 appeared in Pakistan in 1995. A homologous aqueous-based vaccine prepared from the field isolate employed as ring vaccination around the epicentre of the outbreak helped in controlling the disease. Later, in 1998, an outbreak of avian influenza virus (AIV) subtype H9N2, particularly affecting the broilers and broiler-breeders, was dealt with using the same vaccination approach. However, this time, the virus could not be successfully contained in the affected areas. Later on, low pathogenic avian influenza (LPAI) virus subtype H7N3 re-emerged in the broiler-breeder flocks in different poultry estates of the northern area of the country during 2000. This prompted the introduction of a vaccine strategy, whereby both aqueous and oil emulsion vaccines were routinely employed in and around the affected areas. This helped in the control of disease in this region. However, no AI monitoring and control strategy could be launched on a sustainable basis in these areas. In November 2003, new outbreaks of HPAI subtype H7N3 occurred specifically in commercial layers in the southern part of the country, which were never vaccinated against AI in the past. In many cases, subtype H9N2 was also recovered from the diseased flocks, with or without the presence of subtype H7N3. The disease caused heavy losses in the south. An emergency plan to control this outbreak was developed with the help of FAO in this regard. Under this plan, a nationwide AIV monitoring and vaccination strategy was developed. This paper discusses the role of vaccine type and vaccination schedule in the control of HPAI in this country.

Abstract
Amyotrophic lateral sclerosis (ALS) is a neuro-degenerative disorder with both sporadic and familial forms. Approximately 20% of autosomal dominant ALS is caused by mutations in the Cu/Zn superoxide dismutase (SOD1) gene. The causes of the remaining forms of ALS are unknown. The apolipoprotein E (APOE) gene is a known genetic risk factor for Alzheimer disease (AD), another neuro-degenerative disease. The APOE-4 allele increases risk and decreases age at onset in AD. Studies examining ALS and APOE have failed to show a significant effect of APOE on overall risk in ALS. Studies examining the effect of APOE-4 on site of onset in ALS (bulbar or limb) have been contradictory, with some studies showing an APOE association with bulbar onset and others showing no effect. Sample size was limited in these previous reports, particularly with respect to the number of bulbar onset cases (n = 33, 34 and 53). The present study examines a large collaborative data set of ALS patients (n = 363; 95 with bulbar onset) and age-matched neurologically normal controls. The results for these data showed no significant differences in the percentage of subjects with the APOE-4/4 and APOE-4/X genotypes (X = APOE-2 or APOE-3) when comparing cases and controls in both the overall data set or in the data set stratified by site of onset. Similarly, logistic regression analysis in the overall and stratified data set while controlling for sex showed no increase or decrease in risk of ALS associated with the APOE-4 allele. In addition, there were no significant differences in age at onset between patients with APOE-X/X, and APOE-4/4 or APOE-4/X genotypes, overall or stratified by site of onset. We conclude based on these data that the APOE gene is not a major genetic risk factor for site of onset in ALS.
