Spatial price transmission in the onion markets of Bangladesh: An application of NARDL approach.

As the price of local onions is greatly impacted by the price of imported onions at these two levels of the supply chain, the goal of this study was to ascertain whether onion prices in Bangladesh are transmitted asymmetrically at the wholesale and retail levels. To analyze asymmetry, the study employed the nonlinear autoregressive distributed lag (NARDL) model in the short and long run using monthly time series data from January 2006 to December 2020. The NARDL model captures the effects of both positive and negative shocks in the short as well as in the long run.

Empirical assessment of onion supply chain constraints in Bangladesh: A pre-covid to covid situation.

In Bangladesh, Covid-19 has wrecked devastation on people's livelihoods and economies. It began with supply chain disruptions affecting a variety of agricultural products, particularly perishable ones. Onion, the most consumed species in Bangladesh and Asia is also fallen into that category.

Assessing the factors and constraints for value chain development of dairy food products in Bangladesh.

The dairy sector in Bangladesh has shifted from subsistence to commercial and enterprise-driven due to the increasing demand of milk and milk products. In this context, this study was conducted to explore the different participants in dairy value chains and their role in the production, processing and marketing of dairy products. This study addresses the constraints faced by these participants and the factors influencing the value chain efficiency as a case study from Bogura districts of Bangladesh.

Emergence of colistin-resistant in poultry, house flies, and pond water in Mymensingh, Bangladesh.

Objective: Emergence of colistin-resistant (CREC) has generated a sense of public alarm. The objective of this study was to detect the CREC and identification of the gene responsible for such resistance.

Materials And Methods: A total of 150 samples comprising poultry cloacal swab, house flies (), and pond water were collected randomly from Mymensingh, Bangladesh and analyzed.

Method for isolating pure bovine gonadotrophs from anterior pituitary using magnetic nanoparticles and anti-gonadotropin-releasing hormone receptor antibody.

No methods are currently available for rapidly isolating gonadotrophs from the anterior pituitary (AP) in any species. We developed a method for preparing pure bovine gonadotrophs from a heterogeneous AP cell mixture by magnetic separation and our original antibody against the N terminus of bovine gonadotropin-releasing hormone receptor (GnRHR). A bovine AP cell mixture was incubated with the anti-GnRHR antibody, anti-dextran antibody-conjugated secondary antibody and dextran-coated magnetic nanoparticles for magnetic isolation.
