Abstract
An in-house multiplex PCR designed for differential detection of M. bovis, M. avium paratuberculosis (MAP) and M. smegmatis in tissue samples, besides PCR and TaqMan real-time PCR targeting esxA (ESAT-6) and esxB (CFP-10) gene of M. tuberculosis complex (MTC) and IS900 gene targeting MAP were carried out in the present study. Tissue samples comprising of lung, mediastinal lymph node, intestine and mesenteric lymph node from cattle and buffaloes (n=16) suspected to have died of tuberculosis (TB) or paratuberculosis (JD) were collected at post-mortem. Out of 16 animals, only 4 (25%) cases were positive for M. bovis by in-house designed multiplex PCR, where as 9 (56.25%) cases were positive for MTC by both conventional and real-time PCR targeting esxA (ESAT-6) and esxB (CFP-10) genes. Out of 9 TB positive animals, 2 (22.22%) had co-infection with MAP as confirmed by IS900 PCR, real-time PCR and also by in-house multiplex PCR. No samples were found positive for M. smegmatis by the in-house multiplex PCR. Analytical sensitivity of in-house multiplex primers targeting M. bovis, MAP and M. smegmatis were 170 fg/µl, 300 fg/µl and 51 fg/µl of genomic DNA respectively. Analytical sensitivity of primers for both conventional and real time PCR tareting esxA were 8 pg/µl and 800 fg/µl, esxB were 800 fg/µl and 80 fg/µl and IS900 were 30 fg/µl and 3 fg/µl of M. tuberculosis and MAP genomic DNA respectively. The tissue samples were also subjected to histopathology and Immunohistochemical (IHC) staining using ESAT-6 and CFP-10 antibodies for TB and anti-JD anti-serum (raised in rabbit) for JD. All the animals positive for TB (9 of 9) and JD (2 of 2) in PCR and real-time PCR were also positive in histopathology and IHC. Thus, combination of molecular, histopathology and IHC techniques increased the accuracy of TB and JD diagnosis, all of which had same sensitivity and specificity except the in-house multiplex PCR which was comparatively less sensitive in M. bovis detection. However, the molecular methods were found to be more convenient and rapid, capable of making the diagnosis within 6 hours. The study indicated that Real-time PCR was ten times more sensitive than the conventional PCR.

Abstract
Background The job demand-control-social support model has been widely studied in western countries but has not been theoretically addressed on health workers of sub-Saharan African countries. Therefore, this study investigates the relationship between Job Demand-Control-Support Model and job satisfaction in specialized teaching hospitals in Ethiopia. Method A cross-sectional survey was conducted from September 2014 to May 2015 in three public specialized teaching hospitals in Ethiopia. Among 1371 nurses, 360 were selected as sample. Data was collected using Job Content Questionnaire and Job Satisfaction Survey Questionnaire. After the data was collected, it was analyzed using SPSS version16.0 statistical software. The results were analyzed using of descriptive statistics followed by inferential statistics on the variables. Results The result revealed that control variables (gender, age, educational qualification, and work experience) accounted for a significant increment explaining 2.1 percent of the variance in job satisfaction. Job demand and social support together explained 24.5 percent of job satisfaction. Job demand(β=−0.152; p<0.01) had significant but negative relationship with job satisfaction and social support (β=0.458; p<0.01) had significant and positive relationship with job satisfaction. On the other hand, job control (β=0.042; p>0.05) did not have a significant relationship with job satisfaction. Furthermore, there was no straight three-way interaction effect among job demand, job control and social support (β=0.05, p>0.05). Conclusion Job demand and social support are related to nurses' job satisfaction, but job control neither related to nor moderated the relationship between job demands and job satisfaction. Furthermore, there was no joint three-way interaction effect among job demand, job control and social support.

Abstract
Background Recruitment to randomised controlled trials with children is challenging. It is imperative to understand the factors that boost or hinder recruitment of children to clinical trials. We conducted a survey of facilitators and barriers to recruitment to the MAGNETIC trial, using a previously developed web-based tool. Methods MAGNETIC is a multicentre randomised trial of nebulised magnesium in acute severe asthma, recruiting 508 children from 30 UK sites. Recruiters were asked to grade a list of factors from –3 to +3 depending on whether the factor was perceived as a strong, intermediate or weak barrier (–3 to –1) or facilitator (+1 to + 3), and using (0) if it was thought to be not applicable. Free text responses were invited on strategies applied to counter the identified barriers. Results The commonly identified facilitators were motivation and experience of study teams, effective communication and coordination between teams at site and between sites and the Clinical Trials Unit, the presence of designated research nurses, good trial management, clinical trial publicity, simple inclusion criteria, effective communication with parents and presentation of trial information in a simple and clear manner. The commonly identified barriers were heavy clinical workload, shift patterns of work, Good Clinical Practice (GCP) training, inadequate number of trained staff, time and setting of consent seeking, non-availability of research staff out of hours and parents' concerns about their child taking an experimental medicine. Having a designated research nurse, arranging GCP training and trial-related training sessions for staff were the most commonly reported interventions. Conclusions This study highlights important generic and trial-specific facilitators and barriers to recruitment to a paediatric trial in the acute setting and provides information on the recruitment strategies or interventions that were applied to overcome these barriers. This information can be very useful in informing the design and conduct of future clinical trials with children, particularly in the acute or emergency setting. Trial registration ISRCTN, ISRCTN81456894. Registered on 15 November 2007.

Abstract
Polyhydroxyalkanoate (PHA) is a microbial polymer that has been at the forefront of many attempts at tissue engineering. However, the surface of poly(3-hydroxybutyrate-co-4-hydroxybutyrate) (P(3HB-co-4HB)) is hydrophobic with few recognition sites for cell attachment. Various concentrations of fish-scale collagen peptides (FSCPs) were incorporated into P(3HB-co-4HB) copolymer by aminolysis. Later, FSCPs were introduced onto the aminolyzed P(3HB-co-4HB) scaffolds. Introduction of the FSCP groups was verified using Fourier transform infrared spectroscopy and the ninhydrin method. The effect of the incorporation of FSCPs on hydrophilicity was investigated using the water contact angle. As the concentration of FSCPs increased, the water contact angle decreased. In vitro study demonstrated that P(3HB-co-4HB)/FSCP scaffolds provided better cell attachment and growth of L929 mouse fibroblast cells and better cell proliferation. In vivo study showed that P(3HB-co-4HB)/1.5 wt% FSCPs had a significant effect on wound contractions, with the highest percentage of wound closure (61%) in 7 d.

Abstract
Quality of clinical trials has improved steadily over last two decades, but certain areas in trial methodology still require special attention like in sample size calculation. The sample size is one of the basic steps in planning any clinical trial and any negligence in its calculation may lead to rejection of true findings and false results may get approval. Although statisticians play a major role in sample size estimation basic knowledge regarding sample size calculation is very sparse among most of the anesthesiologists related to research including under trainee doctors. In this review, we will discuss how important sample size calculation is for research studies and the effects of underestimation or overestimation of sample size on project's results. We have highlighted the basic concepts regarding various parameters needed to calculate the sample size along with examples.

Abstract
Canine parvovirus (CPV) causes hemorrhagic enteritis, especially in young dogs, leading to high morbidity and mortality. It has four main antigenic types CPV-2, CPV-2a, CPV-2b and CPV-2c. Virus protein 2 (VP2) is the main capsid protein and mutations affecting VP2 gene are responsible for the evolution of various antigenic types of CPV. Full length VP2 gene from field isolates was amplified and cloned for sequence analysis. The sequences were submitted to the GenBank and were assigned Acc. Nos., viz. KP406928.1 for P12, KP406927.1 for P15, KP406930.1 for P32, KP406926.1 for Megavac-6 and KP406929.1 for NobivacDHPPi. Phylogenetic analysis indicated that the samples were forming a separate clad with vaccine strains. When the samples were compared with the world and Indian isolates, it was observed that samples formed a separate node indicating regional genetic variation in CPV.

Abstract
The main focus of this study is the incorporation of collagen peptides to fabricate P(3-hydroxybutyrate-co-4-hydroxybutyrate) [P(3HB-co-4HB)] nano-fiber construct to further enhance surface wettability and support cell growth while harbouring desired properties for biodegradable wound dressing. Simultaneous electrospinning of nanofiber P(3HB-co-4HB)/collagen peptides construct was carried out using dual syringe system. The wettability of the constructs increased with the increase in 4HB molar fraction from 20mol% 4HB [53.2°], P(3HB-co-35mol%4HB)[48.9°], P(3HB-co-50mol%4HB)[44.5°] and P(3HB-co-82mol%4HB) [37.7°]. In vitro study carried out using mouse fibroblast cells (L929) grown on nanofiber P(3HB-co-4HB)/collagen peptides construct showed an increase in cell proliferation. In vivo study using animal model (Sprague Dawley rats) showed that nanofibrous P(3HB-co-4HB)/collagen peptides construct had a significant effect on wound contractions with the highest percentage of wound closure of 79%. Hence, P(3HB-co-4HB)/collagen peptides construct suitable for wound dressing have been developed using nano-fabrication technique.

Abstract
Pregnancy is associated with various ocular changes which can be either physiological or pathological or modification in pre existing conditions. These changes are mostly transient, however some can become permanent. Physiological ocular changes include change in ocular adenexa, tear film composition, cornea, refraction and intraocular pressure. Pathological ocular changes occur as a result of pregnancy induced hypertension, pseudotumour cerebri, vascular occlusive disorders and amniotic fluid embolism. Some of the pre-existing ocular conditions worsen during pregnancy which include diabetic retinopathy, grave’s disease, toxoplasmosis, pituitary tumours, meningioma and uveal tumours. Others show improvement in pregnancy such as uveitis, optic neuritis and multiple sclerosis. Yet others are associated with exacerbations during postpartum period as optic neuritis. Knowledge of these changes is important for both ophthalmologists and gynaecologists for proper management of these patients. Also the treatment modalities for various disorders differ between pregnant and non pregnant females. The ophthalmic medications should be used cautiously during pregnancy and lactation to avoid harmful effects in the mother and the fetus. The materials published in Pubmed, Google Scholar webpages and standard books have been used for preparing this paper.
