Dead Zone Measurement Of The P-Selectin/PSGL-1 Interaction
PEI 10 nm INTRODUCTION Induced on activated endothelial cells and platelets, P-selectin is a cell adhesion molecule that plays a critical role in the inflammatory and thrombotic processes. P-selectin glycoprotein ligand 1 (PSGL-1) is expressed on leukocytes, and its interaction with P-selectin mediates the flowing cells tethering to and rolling on the blood vessel wall [1]. In this dynamic envi...

Viruses can swap DNA between bacteria that live in regions of the oceans with little or no oxygen.
متن کاملBringing new life to the dead zone.
The Gulf of Mexico “dead zone” reached a record 7,700 square miles in the summer of 1999. That year, heavier flow in the Mississippi River brought an abundance of nutrients to the Gulf, resulting in hypoxia, or inadequate dissolved oxygen in bottom waters that forces bottom-dwelling animals to either flee or die. With the year 2001 have come legislative efforts to reduce the dead zone—if not ki...
متن کاملDead Zone Compensation in Pneumatic Servo Systems
This paper presents an approach for dead zone compensation in pneumatic position servo systems. The dead zone is an inherent nonlinearity in pneumatic servovalves, where for a range of input control values, the valve gives no output flow. Although pneumatic actuators are very common in industry, they have limitations in servo pneumatic applications that are caused by typical non-linearities of ...
متن کاملEnvironmental factors affecting the levels of legacy pesticides in the airshed of Delaware and Chesapeake Bays, USA.
Organochlorine insecticides and their degradation products contribute to toxicity in Chesapeake Bay, USA, sediments and affect the reproductive health of avian species in the region; however, little is known of atmospheric sources or temporal trends in concentrations of these chemicals. Weekly air (n = 265) and daily rain samples (n = 494) were collected over 2000 to 2003 from three locations i...
