Cells need backward motor to move forward
Cells need backward motor to move forward ytoplasmic dynein associates with a variety of intracellular cargos and pulls them toward the minus ends of microubules. But this retrograde motor protein is also essential for forward cell migration, as Dujardin et al. demonstrate on page 1205. After observing dynein and its associated regulatory proteins at the leading edges of migrating cells in a mo...
متن کاملWave fronts may move upstream in semiconductor superlattices
In weakly coupled, current biased, doped semiconductor superlattices, domain walls may move upstream against the flow of electrons. For appropriate doping values, a domain wall separating two electric-field domains moves downstream below a first critical current, it remains stationary between this value and a second critical current, and then moves upstream above. These conclusions are reached ...
متن کاملLibyan National Health Services The Need to Move to Management-by-Objectives
In the last four decades, there has been a substantial horizontal expansion of health services in Libya. This resulted in improvement in morbidity and mortality, in particularly those related to infectious disease. However, measures such as the national performance gap indicator reveal an underperforming health system. In this article, we discuss aspects related to the Libyan health system and ...
متن کاملRationale for multiple risk intervention: The need to move from theory to practice
Incidence of cardiovascular (CV) and metabolic disease is increasing, in parallel with associated risk factors. These factors, such as low-density lipoprotein (LDL)-cholesterol, elevated blood pressure, obesity, and insulin resistance have a continuous, progressive impact on total CV risk, with higher levels and numbers of factors translating into greater risk. Evaluation of all known modifiabl...
متن کاملThe need to move from 6-minute walk distance to outcome trials in pulmonary arterial hypertension.
Assessment of change in exercise capacity using the 6-min walk distance (6MWD) test has been the primary end-point in the majority of pulmonary arterial hypertension (PAH) clinical trials. The 6MWD has some advantages as an end-point in such studies. It is simple and inexpensive to perform, reproducible and validated. In short-term studies with small patient numbers, as is typical in a rare dis...
