Mesenchymal cell migration as exhibited by fibroblasts is distinct from amoeboid cell migration and is characterized by dynamic competition among multiple protrusions, which determines directional persistence and responses to spatial cues. Localization of phosphoinositide 3-kinase (PI3K) signaling is thought to play a broadly important role in cell(More)
The extracellular signal-regulated kinase (ERK) signaling pathway controls cell proliferation and differentiation in metazoans. Two hallmarks of its dynamics are adaptation of ERK phosphorylation, which has been linked to negative feedback, and nucleocytoplasmic shuttling, which allows active ERK to phosphorylate protein substrates in the nucleus and(More)
It has long been appreciated that spatiotemporal dynamics of cell migration are under the control of intracellular signaling pathways, which are mediated by adhesion receptors and other transducers of extracellular cues. Further, there is ample evidence that aspects of cell migration are stochastic: how else could it exhibit directional persistence over(More)
Cell migration is central to physiological responses to injury and infection and in the design of biomaterial implants. The ability to tune the properties of adhesive materials and relate those properties in a quantitative way to the dynamics of intracellular processes remains a definite challenge in the manipulation of cell migration. Here, we propose the(More)
GPRS offers the user can always on connection to Internet and Intranet. Some of the services may require high level of security. This can be financial transaction over the Internet, or exchange of confidential documents from a company’s Intranet to an employee. It is important to have strong focus on the security, so companies and persons that(More)
Food safety is a global concern and Bangladesh is no exception. In last few decades, fruit and fruit processing industries have grown rapidly in Bangladesh. To achieve maximum quality in terms of visual appearance, texture, flavor and nutritional value, fruits must be harvested at proper maturity. However, after harvesting, rapid ripening of fruits is(More)
The paper explores the effect of the quantity of methanol on biodiesel production and its characteristics from Waste Frying Oil (WFO). Based on the results, it progresses to develop a continuous process simulation that can be scaled-up for commercial applications. Pretreatment of WFO was carried out by acidesterification, followed by base-catalyzed(More)
