  Objective: The study aimed to molecular characterization of Pasteurella multocida local strain using Enterobacterial Repetitive Intergenic Consensus (ERIC), 13 virulence genes and the outer membrane protein (OmpH) gene. Also, development of diagnostic markers by multiplex PCR from investigated genes. Methodology: The ERIC-PCR was used for the detection of the finger print of Pasteurella multocida local strain isolated from rabbits. Polymerase Chain Reaction (PCR) with specific primers of the virulence genes and OmpH gene was used for molecular characterization of Pasteurella multocida local strain. The multiplex-PCR protocol was used to develop diagnostic genes markers. Results: Pasteurella multocida ERIC pattern was identified as seven DNA bands ranging from less than 100-850 bp. The results determined the molecular sizes of toxA, pfhA, soda, nanB, nanH, fimA, hsf-1, hsf-2, hgbA, hgbB, ptfA, oma87, tbpA and OmpH genes. Four multiplex-PCR were configured from investigated genes. Multiplex 1 amplified both of hgbB and oma87 genes. Multiplex 2 included fimA and ptfA genes. Multiplex 3 used nanB and hgbB genes. Multiplex 4 amplified nanB and ptfA genes. Conclusion: Molecular characterization of P. multocida local strain using Enterobacterial Repetitive Intergenic Consensus (ERIC), 13 virulence genes and the outer membrane protein (OmpH) gene provided data information that could be used as diagnostic tool, epidemiological markers and in vaccine development.

  The present study attempts to examine the scenario of buffalo production in SAARC countries. The buffalo plays a very important role in the SAARC countries which constitutes 73.77% of world buffalo population. The SAARC region has a great biodiversity of buffalo germplasm, including the world famous buffaloes Murrah and Nili-Ravi-renowned for high milk production potential. The SAARC countries share 93.19% of world buffalo milk production where India and Pakistan contributes 67.99 and 23.96%, respectively. About 71.4% of world buffalo meat is produced in South Asian countries. Although, buffalo is an essential part of livestock in SAARC countries, it has never been addressed in Bangladesh and always neglected despite their important role in the national economy. In Bangladesh, the total buffalo population are 1.457 million heads that are managed in household subsistance farming and extensive bathan farming in saline coastal region that are used as a draught animal and partially for milk and meat production. This study has tried to unreath the present scenario of buffalo production in SAARC countries and find out the constraints of buffalo production and recommendations of buffalo development in Bangladesh. This study has also explored the further development of buffalo in SAARC countries as well as in Bangladesh.

  The present study attempts to examine the scenario of poultry industry and the role of private sector for its development in Bangladesh. In Bangladesh, more than half of the people is based on agricultural and livestock farming. The poultry sector is an integral part of farming systems and has created both direct and indirect employment opportunity, improved food security and enhanced supply of quality protein to people’s meals, contributing country’s economic growth and reducing poverty level in rural and urban areas of Bangladesh. The present meat and egg production can meet only 68 and 64% of the national demand. The demand for meat, egg and meat and egg products have been expanding dramatically with income growth, population growth, urbanization and dietary changes. Recognizing this fact, the government and the private sector are working together to solve the problem in poultry industry through various development activities. Apart from this, government is encouraging private sectors and NGOs to undertake steps for the development of poultry by liberalizing its present policy. This review study has tried to unearth the present scenario of poultry industry in Bangladesh, contribution of private enterprises for the development of poultry sectors, marketing of poultry and poultry products, problems and constraints of poultry industry and explores the scope and opportunity of poultry industry of Bangladesh. This study has also explored the status of poultry business development through various programs designed and implemented by private sectors.

  Aims  Wolfram syndrome, also known as DIDMOAD, is a relatively rare inherited neurodegenerative disorder, first evident in childhood as an association of juvenile-onset diabetes mellitus and optic atrophy, followed by diabetes insipidus and deafness. The aim of the study was to examine the clinical profile of patients with DIDMOAD syndrome presenting to a tertiary care hospital in north India.

Methods  Clinical presentation of juvenile-onset diabetes mellitus fulfilling the diagnosis of Wolfram syndrome was studied using a prepared standardized form.

Results  Subjects with juvenile-onset non-autoimmune diabetes mellitus attending the diabetic clinic at a tertiary care centre in north India were followed for 10 years and a diagnosis of fully developed Wolfram syndrome was confirmed in seven individuals. The series consisted of five male and two female patients with a mean age of 17.5 ± 7.34 years. Two subjects had consanguinity and none had any other family member affected. Optic atrophy was present in all, sensorineural hearing loss in 4/7, central diabetes insipidus in 4/7 and nephrogenic diabetes insipidus in 2/7 subjects. The new associations found were: spastic myoclonus, short stature with pancreatic malabsorption, nephrogenic diabetes insipidus, cyanotic heart disease and choledocholithiasis with cholangitis. Genetic analysis revealed mutation in exon 8 of the WFS1 gene in all the cases studied.

Conclusions  The present clinical series of Wolfram syndrome reveals a varied clinical presentation of the syndrome and some new associations.

  Reducing time and efficient project execution is an objective in many industries and project management is one of the important keys for lead the company to this allegation. The project manager needs some tools for lead the firm to the success. Collaboration is one way to success and collaboration has many types, one kind is electronic collaboration. On the other hand, small and Medium Size Enterprises (SMEs) are a part of manufacturing industries. Combining a literature review with our empirical experience we found that relationship between the project manager and related departments for production is essential for reducing time and cost in new product development. In this study, we describe about some definition of project management, E-collaboration, SMEs and new product and review some articles around this area.

  Liquid Chromatographic Mass Spectrometric System (LCMSMS) method was developed and validated in shrimp matrix for determination of nitrofuran metabolites in the laboratory of fish inspection and quality control, Department of Fisheries, Matshya Bhaban, Dhaka, Bangladesh. This confirmatory method was used for testing samples for residues of the metabolites of the following nitrofuran compounds, furazolidone (3-amino-2-oxazolidinone, AOZ); furaltadone (5-methyl-morpholino-3-amino-2-oxazolidinone, AMOZ); nitrofurazone (semicarbazide, SEM) and nitrofurantoin (1-aminohydantoin, AHD) in shrimp. The data were generated (3 levels and seven replicates per level) on each of three days for shrimp. The mean recoveries from the tissues were 88-110%, the decision limits (CCα) were 0.12-0.23 ppb and the detection capabilities (CCα) 0.21-0.38 ppb. CCα and CCβ were calculated using the procedure set out in ISO Guide 11843. Nevertheless, CCα value for all nitrofuran metabolites can be investigated and meet the specified easily met the specified EU MRPL of 1 μg kg-1 ranged from 0.12-0.23 μg kg-1 and suitable for routine quality control operations.

  This study presents a design of dielectric resonator antenna with filtering capability at C-band. The antenna design consists of dielectric substrate on which a dielectric material with permittivity of 10 is designed to work as radiated element. A pair of separated aperture coupling slots are etched on the ground plane to couple the microstip feed line to the top dielectric material. Open stub with microstip feedline is designed for filtering function. The proposed antenna can achieve a wide bandwidth of 456.5 MHz in the range from 4.8911-5.3476 GHz. High order harmonic suppression and low order harmonic suppression are achieved which improve the antenna filtering response. The antenna can achieve a gain of 6.34 dBi, return loss <-25 dB and VSWR of 1.1 dB. The proposed dielectric resonator antenna has high performance with good filtering response which is useful feature in modern wireless communication systems.
