Abstract
Improved tools are required to study immunopathogenesis of tuberculosis (TB). Mycobacterium tuberculosis antigen-stimulated T cell-based assays can detect TB but are less effective when responses are compromised such as in severe disease. We investigated immune responses to M. tuberculosis whole sonicate (MTBs), recombinant antigens ESAT6 and CFP10 in whole blood cells of healthy endemic controls (EC, n = 42) and patients with pulmonary (PTB, n = 36) or extrapulmonary (ETB, n = 41) disease. Biomarkers of T cell activation (IFNγ) or modulation (IL10) and chemokines, CXCL9, CXCL10 and CCL2, secretion were measured. MTBs, ESAT6 and CFP10 all induced IFNγ responses in TB. ESAT6-induced IFNγ was elevated in TB as compared with EC. MTBs stimulated the highest IFNγ levels but did not differentiate between TB and EC. However, MTBs-induced CXCL10 (P = 0.004) was reduced, while IL10 (P < 0.001) was raised in TB as compared with EC. Between sites, MTBs-induced CCL2 (P = 0.001) and IL10 secretion was higher in PTB than ETB (P < 0.001). In comparison of disease severity, MTBs-induced IFNγ (P = 0.014) and CXCL10 (P = 0.022) levels were raised in moderate as compared with far advanced PTB. In ETB, MTBs-induced IL10 levels were greater in less-severe (L-ETB) than in severe disseminated (D-ETB) cases, P = 0.035. Within the L-ETB group, MTBs-induced IFNγ was greater in patients with tuberculous lymphadenitis than those with pleural TB (P = 0.002). As immune responses to MTBs were differentially activated in TB of different sites and severity, we propose the utility of MTBs-induced IFNγ, CXCL10 and IL10 as biomarkers in TB.

Abstract
Biomaterials, which can contain appropriate biomechanical and/or biochemical cues, are increasingly being investigated as potential scaffolds for tissue regeneration and/or repair for treating myocardial infarction, heart failure, and peripheral artery disease. Specifically, injectable hydrogels are touted for their minimally invasive delivery, ability to self-assemble in situ, and capacity to encourage host tissue regeneration. Here we present detailed methods for fabricating and characterizing decellularized injectable cardiac and skeletal muscle extracellular matrix (ECM) hydrogels. The ECM derived hydrogels have low cellular and DNA content, retain sulfated glycosaminoglycans and other extracellular matrix proteins such as collagen, gel at physiologic temperature and pH, and assume a nanofibrous architecture. These injectable hydrogels are amenable to minimally invasive, tissue specific biomaterial therapies for treating myocardial infarction and peripheral artery disease.

Abstract
Serum levels of the inflammatory C-X-C motif chemokine 10 (CXCL10) are raised in tuberculosis (TB). CXCL10 gene expression is downregulated in monocytes by metabolically active vitamin D3 (1,25dihydroxy vitamin D). Stratification of patients by serum 25hydroxyvitamin D (25[OH]D) levels at baseline showed that treatment-induced decrease in CXCL10 occurred in those with 'insufficient' and 'deficient' but not in those with 'optimal' levels. In the deficient group, 25(OH)D showed an inverse correlation with CXCL10 levels. CXCL10 may thus be a useful biomarker for the follow-up of response to treatment. However, CXCL10 levels should be interpreted taking into account the baseline serum vitamin D levels of the TB patients.

Abstract
Essential genes are those genes that are needed by organisms at any time and under any conditions. It is very important for us to identify essential genes from bacterial genomes because of their vital role in synthetic biology and biomedical practices. In this paper, we developed a support vector machine (SVM)-based method to predict essential genes of bacterial genomes using only compositional features. These features are all derived from the primary sequences, i.e., nucleotide sequences and protein sequences. After training on the multiple samplings of the labeled (essential or not essential) features using a library for SVM, we obtained an average area under the ROC curve (AUC) of about 0.82 in a 5-fold cross-validation for Escherichia coli and about 0.74 for Mycoplasma pulmonis. We further evaluated the performance of the method proposed using the dataset consisting of 16 bacterial genomes, and an average AUC of 0.76 was achieved. Based on this training dataset, a model for essential gene prediction was established. Another two independent genomes, Shewanella oneidensis RW1 and Salmonella enterica serovar Typhimurium SL1344 were used to evalutate the model. Results showed that the AUC sores were 0.77 and 0.81, respectively. For the convenience of the vast majority of experimental scientists, a web server has been constructed, which is freely available at http://cefg.uestc.edu.cn:9999/egp.

Abstract
BK viral infection is an important cause of renal transplant dysfunction and failure. Current strategies utilize surveillance for infection with DNA polymerase chain reaction assays and modulation of immunosuppression. Many viruses including polyomaviruses encode microRNAs (miRNAs). We have detected BK virus (BKV) encoded miRNAs in the blood of infected renal transplant recipients, and see a strong correlation between BKV encoded miRNA and BKV DNA in blood and a relationship between levels of bkv-miR-B1-5p and the presence of biopsy-proven BK viral nephropathy. Further research is needed to determine whether the detection of this and other virally encoded miRNAs may be useful in the diagnosis of active viral replication.

Abstract
Suppressors of cytokine signalling (SOCS) molecules inhibit cytokine signalling and may regulate protective immunity in tuberculosis (TB). We investigated the association of SOCS with disease progression in patients with pulmonary TB. For this purpose, we studied peripheral blood mononuclear cells (PBMCs) and T cells from patients with pulmonary TB (TB, n=33) and healthy endemic controls (EC, n=15). Cases were stratified into those with moderately advanced (Mod-PTB) or far advanced disease (Adv-PTB). Interferon-gamma (IFN-γ), SOCS1 and SOCS3 gene expression was determined by RT-PCR. Statistical analysis was performed using the Mann-Whitney test. Levels of IL6 (P=0.018) and IL10 (P=0.013) were found to be elevated in PBMC supernatants from patients with TB as compared with EC. SOCS1 mRNA gene expression in T cells from patients with TB was increased as compared with that of EC (P=0.02). In addition, levels of SOCS1 mRNA transcripts were found to be elevated in PBMCs of Adv-PTB as compared with Mod-PTB (P=0.008) cases. Our data show that raised SOCS1 levels are associated with increased disease severity in TB. As SOCS1 regulates IFN-γ-driven immunity and SOCS1 can be further upregulated by IL6 levels, the increase in SOCS1 in severe disease indicates a mechanism by which mycobacteria impede disease control in TB.

Abstract
Horizontal gene transfer is an important mechanism for the evolution of microbial genomes, and many horizontal gene transfer events are facilitated by genomic islands (GIs). Until now, few reports have provided evidence for the co-evolution of horizontally transferred genes and their hosts. We obtained 17 groups of homologous GIs, all of which appear in 8 or more bacterial strains of the same species or genus. Using phylogenetic analyses, we found that the topological structure of a distance tree based on the proteins of each group of homologous GIs was consistent with that based on the complete proteomes of the hosts. This result clearly indicates that GIs and their bacterial hosts have co-evolved. In addition to presenting and providing evidence for a novel concept, i.e., the co-evolution of GIs and their bacterial hosts, we also describe a new and interesting detail for the phylogenetic analysis of horizontally transferred genes: consistent phylogenetic trees can be obtained by focusing on homologous GIs despite the commonly accepted theory that the phylogenies of horizontally transferred sequences and host organisms should be inconsistent.

Abstract
Cryoglobulinaemia is a systemic inflammatory condition characterised by immune complex-mediated small-to-medium-sized vasculitis. It has a wide variety of presentations ranging from bruising, neuropathy, and hepatosplenomegaly to acute renal failure. Mixed cryoglobulinaemia is the most common type and is strongly associated with hepatitis C. Management approaches include use of cyclophosphamide, prednisolone, and plasmapheresis, with differing views on alternative treatments in resistant cases. Rituximab has emerged as an attractive option in resistant cases on account of its potent immunosuppressive effects on B cells. We describe a case of type 2 mixed cryoglobulinaemia in association with non-Hodgkin's lymphoma resistant to standard treatments which responded well to rituximab. This case is remarkable as mixed cryoglobulinaemia associated with non-Hodgkin's lymphoma presenting with nephritis is unusual, and, contrary to the high rate of recurrence in lymphoma-related cryoglobulinaemia, our patient has not shown any recurrence over 24 months. This highlights an alternative treatment modality which can be used in patients not responsive to existing managements for this condition with benefits of minimal side effects and no oncogenetic potential.

Abstract
AIMS South Asians in the UK have high cardiovascular disease (CVD) mortality. Therefore, this population is likely to benefit from screening programmes. To address this issue, an initiative was set up between the Royal Free Hampstead NHS Trust, H.E.A.R.T. UK and two Hindu temples in North London to provide screening for CVD risk factors in the community. METHODS A total of 434 individuals of Gujarati Indian origin were screened. Measurements included anthropometry, blood pressure and lipid profiles. Three different scoring systems: Framingham, Joint British Societies' 2 and QRISK2 were used to estimate CVD risk. RESULTS At least one modifiable CVD risk factor was present in 92% of the individuals screened; 52% were hypertensive, 40% were obese, 75% had central adiposity and 10% had total cholesterol/high density lipoprotein cholesterol ratio > 6. In addition, 37% of a subset of 104 individuals with a fasting sample fulfilled the diagnostic criteria for metabolic syndrome. Overall, 15% of participants screened had a 10-year CV risk score > 20% using QRISK2. The three risk score calculators showed moderate agreement: QRISK2 and JBS2 (kappa 0.61, 95% CI 0.54-0.67), QRISK2 and Framingham (kappa 0.63, 95% CI 0.57-0.70) and JBS2 and Framingham (kappa 0.70, 95% CI 0.64-0.75). CONCLUSIONS A high prevalence of modifiable risk factors for CVD was detected in the population screened.
