Abstract
Haemonchus contortus is an economically important gastrointestinal parasite that infects primarily sheep and goats. To survive inside the host, the parasite must overcome the host immune response. In this study, we have identified and characterized a complement-C3-binding protein (H.c-C3BP) from this parasite employing biochemical and molecular biology tools. Initially, a truncated form of the protein was isolated from the excretory-secretory products of the parasite using C3-Sepharose column that facilitated its identification by mass spectroscopy. Subsequently, the parent molecule was generated in E. coli, and sequence analysis confirmed it as glyceraldehyde-3-phosphate dehydrogenase (GAPDH). GAPDH reacted with the antiserum raised against the truncated protein, and the truncated protein reacted with anti-GAPDH antiserum. The protein inhibited complement function as measured by haemolytic assay and membrane attack complex (MAC) formation. Sera from H. contortus-infected animals reacted with GAPDH as well as the truncated form of the protein, which further lend support to protein secretion. Thus, the C3-binding property of H. contortus GAPDH is a new function, and it represents a new entity of complement-binding protein. Identification and characterization of H.c-C3BP should facilitate development of new therapeutics considering a key role of this protein in immune modulation.

Abstract
Alzheimer's disease (AD) is characterized by extracellular amyloid-β (Aβ) deposition, which activates microglia, induces neuroinflammation and drives neurodegeneration. Recent evidence indicates that soluble pre-fibrillar Aβ species, rather than insoluble fibrils, are the most toxic forms of Aβ. Preventing soluble Aβ formation represents, therefore, a major goal in AD. We investigated whether microvesicles (MVs) released extracellularly by reactive microglia may contribute to AD degeneration. We found that production of myeloid MVs, likely of microglial origin, is strikingly high in AD patients and in subjects with mild cognitive impairment and that AD MVs are toxic for cultured neurons. The mechanism responsible for MV neurotoxicity was defined in vitro using MVs produced by primary microglia. We demonstrated that neurotoxicity of MVs results from (i) the capability of MV lipids to promote formation of soluble Aβ species from extracellular insoluble aggregates and (ii) from the presence of neurotoxic Aβ forms trafficked to MVs after Aβ internalization into microglia. MV neurotoxicity was neutralized by the Aβ-interacting protein PrP and anti-Aβ antibodies, which prevented binding to neurons of neurotoxic soluble Aβ species. This study identifies microglia-derived MVs as a novel mechanism by which microglia participate in AD degeneration, and suggest new therapeutic strategies for the treatment of the disease.

Abstract
Ghrelin, a novel motilin-related endogenous ligand for growth hormone secretagouge receptor, is implicated in various biological functions, including regulation of female reproduction. But the presence of ghrelin and its role in reproductive functions in buffalo, a species with poor reproductive efficiency, is not known. In the present study full-length ghrelin cDNA was isolated from bubaline abomasum, which encodes the entire prepropeptide of 116 amino acids. The deduced amino acid sequence of ghrelin of buffalo showed >95% and 31% identity with that of ruminants (cattle, sheep, and goat) and humans, respectively. Analysis of synonymous and nonsynonymous nucleotide substitutions in the coding region of ghrelin indicated that these sequences of different species have been under purifying selection. The 3995-bp amplicon of ghrelin gene consisting of 4 exons and 3 introns was cloned with genomic DNA from buffalo. Further, ghrelin expression was determined by quantitative real-time PCR, in situ hybridization, and immunohistochemistry in bubaline endometrial tissues at different stages of the estrous cycle and early pregnancy. Our results indicated the persistent expression of ghrelin mRNA and protein in the endometrium during stage I (day 3-5), stage II (day 6-15), and stage III (day 16-21) of the estrous cycle and also during early (~day 30-40) pregnancy. Immunohistochemistry and quantitative real-time PCR experiments indicated the relatively higher expression of ghrelin in the endometrium during stage II (day 6-15) of the estrous cycle and early pregnancy than during stage I (day 3-5) and stage III (day 16-21) of the estrous cycle, but no statistically significant difference in ghrelin expression was observed among stages. To conclude, the results of the present study indicate the persistent expression of ghrelin in the uterine endometrium throughout the estrous cycle and in early pregnancy which might be helpful in determining its role in buffalo reproduction.

Abstract
Lipomas are the most commonly encountered benign mesenchymal tumour, arising in any location where fat is normally present. Lipomas in the head and neck are rare in all age groups. Cases of vascular sheath lipomas in the femoral region have only been reported in adults. In children, vascular sheath lipomas have not been described to date. We report the first case of a carotid sheath lipoma in a seven-year-old boy. He had a non-tender soft mass with ill defined borders occupying the left upper part of the neck. Magnetic resonance imaging showed a mass at the bifurcation of the left common carotid artery without involving the same. The mass was hyperintense on T1 and T2 weighted sequences, suggestive of a lipoma. The lipoma was enucleated after incising the carotid sheath, safeguarding its contents. Histopathology confirmed it as a lipoma.

Abstract
INTRODUCTION The purpose of this study is to estimate the current lifetime economic burden of traumatic spinal cord injury (tSCI) in Canada from a societal perspective, including both direct and indirect costs, using an incidence-based approach. METHODS Available resource use and cost information for complete/incomplete tetraplegia and paraplegia was applied to the estimated annual incidence of tSCI, by severity, in Canada. RESULTS The estimated lifetime economic burden per individual with tSCI ranges from $1.5 million for incomplete paraplegia to $3.0 million for complete tetraplegia. The annual economic burden associated with 1389 new persons with tSCI surviving their initial hospitalization is estimated at $2.67 billion. CONCLUSION While the number of injuries per year in Canada is relatively small, the annual economic burden is substantial.

Abstract
BACKGROUND Coverage of health in Nepali print media is quite a recent phenomenon despite readers' ample appetite for it. Dominated by politics, Nepal's print media has been marginally publishing news pieces, features, editorials and op-ed articles, photographs and cartoons on health, though marginally. But the media did not wake up to the issues of human resources for health until lately. METHODS We content analysed the coverage of health issues including, human resources for health in select Nepali print media Kantipur, Nagarik and Annapurna Post of select three months in 2012 April, August and December. News pieces and their placements, Op-eds, editorials, features, letters to the editor, photos and cartoons were subjected to analysis. RESULTS Over the study period, the papers covered 544 health news pieces, 44% of political news pieces. Health workforce news pieces contributed 24% to it. However, only 10% of the health news made to the front pages. Coverage of health in editorials, features, Op-eds, photographs, cartoons and letters to the editor is even more meager. For example, only 7% of the editorials are relating to health. CONCLUSIONS Health is prioritized far less by the print media than politics despite the reader's appetite for it. Print media should give health a top priority, particularly in those areas that relate to health systems like human resources for health, for their massive impact on the lives of the people.

Abstract
The past few years have seen significant advances in the use of modern proteomics approaches for biological discoveries. Among the fields impacted by proteomics is that of epigenetics, as mass spectrometry-based approaches have allowed the identification and characterization of transcriptional regulators, epigenetic marks, and the constantly evolving epigenetic landscape of a cell in health and disease states. These studies have substantially expanded our understanding of critical genes that mediate cell processes, such as differentiation, cell cycle regulation, and apoptosis. Not surprisingly, a great emphasis has been placed on defining factors that are de-regulated in cancers, in an attempt to define new and specific targets for therapeutic design. Differential gene expression observed during carcinogenesis can be induced by aberrant activities of transcription factors and chromatin remodeling enzymes. Through a series of recent mass spectrometry studies of histone deacetylases and nuclear receptors, Deleted in Breast Cancer 1 (DBC1) has emerged as a master regulator of transcriptional processes. DBC1 acts as a modulator of cellular epigenetic mechanisms and is frequently associated with human metastasis. Through its negative regulation of SIRT1 and HDAC3 deacetylation activities, DBC1 has a broad impact on gene expression, downstream cellular pathways, and associated human diseases. Here, we review the identified roles of DBC1, highlighting the critical contribution of mass spectrometry to these findings. Additionally, we provide a perspective of integrative proteomics approaches that can continue to shed light on the interplay between DBC1 and its protein targets, helping to further define its role in epigenetic modifications and to identify novel targets for cancer therapy.

Abstract
PURPOSE To investigate enlargement of prostate volume by edema during brachytherapy seed implantation and develop a nomogram model to calculate air-kerma strength (AKS) required for implantation of the enlarged transient prostatic volume. MATERIALS AND METHODS The prostate volume was measured prior and after seed implantation using trans-rectal ultrasound imaging in the operating room to obtain volume enlargement. A nomogram model was developed that calculates AKS required for implantation of the enlarged transient prostate volume with optimal dose coverage. RESULTS The measured prostate enlargement in this study was up to 60% of the initial volume. The effective prostatic volume enlargement was calculated for three isotopes: 125I, 103Pd and 131Cs. The effective volume enlargement for 125I implants was relatively small (< 10%) because of its long half-life. For 103Pd and 131Cs with short half-lives, additional AKS up to 20% and 30%, respectively, might be required to provide appropriate dose coverage of possible enlarged prostatic volumes. CONCLUSIONS Prostate volume enlargement should be considered to obtain optimal dose coverage particularly for short half-life isotopes such as 131Cs and 103Pd. The nomogram model developed in this work provides the AKS required for implants with a wide range of prostatic volume enlargements (5-100%) for three isotopes.

Abstract
BACKGROUND This paper aims to demonstrate how an online planning intervention to enhance contraceptive and condom use among adolescents was viewed by sexual health professionals. It identifies feedback that has facilitated improvement of the intervention both in terms of potential effectiveness and sustainability in practice. The data illustrate how professionals' feedback can enhance intervention development. METHOD Ten practitioners (two male; eight female) representing a range of roles in sexual health education and healthcare were given electronic copies of the prototype intervention. Interviews were conducted to elicit feedback. Transcripts of the interviews were subjected to thematic analysis. RESULTS Practitioners provided positive feedback about the intervention content, use of on-line media, the validity of planning techniques and the inclusion of males in contraceptive planning. Issues with rapport building, trust, privacy, motivation, and time and resources were raised, however, and the promotion of condom carrying was contentious. CONCLUSIONS Professionals' feedback provided scope for developing the intervention to meet practitioners' concerns, thus enhancing likely feasibility and acceptability in practice. Ways in which particular feedback was generalisable to wider theory-based and online intervention development are explored. Some responses indicated that health practitioners would benefit from training to embed theory-based interventions into sexual health education and healthcare.

Abstract
Introduction: There is no published data in Nepal regarding the use of gefi tinib in patients with non-small cell lung cancer (NSCLC). Therefore, a retrospective analysis was conducted to evaluate the response and toxicity profi le of Gefi tinib alone in patients with advanced NSCLC and unknown epidermal growth factor receptor (EGFR) status.
Methods: A single institutional retrospective study was conducted for the period from January 2004 to December 2006 involving patients with locally advanced or metastatic NSCLC who received gefi tinib as monotherapy Primary objective was to evaluate the objective tumor response rate.
Results: A total of 36 patients with advanced NSCLC who received gefi tinib 250 mg orally once daily as 1st, 2nd, 3rd, and 4th line treatment in 7, 14, 9, and 6 patients respectively were included in the analysis. Comparable number of patients pertaining to sex, smoking status, and tumor histology were included. The overall response rate at 3 months was 60% including 47% in males and 68% in females. After one month 38% and 6.6% patients with adenocarcinoma and squamous histology respectively responded to gefi tinib therapy. The median progression-free survival was 5.7 months. Toxicities were generally mild with diarrhea, rash and pruritus being the most commonly observed side effects.
Conclusion: In this single-center experience, gefi tinib demonstrated clinically signifi cant response in overall population and provided good palliation in pretreated patients.
