Ribonucleoprotein particles are central to numerous cellular pathways, but their study in vitro is often complicated by heterogeneity and aggregation. We describe a new technique to characterize these complexes trapped as homogeneous species in a nondenaturing gel. Using this technique, in conjunction with phosphorothioate footprinting analysis, we identify the proteinbinding site and RNA foldi...

After some preliminary remarks upon pathophysiologic and anatomo-surgical aspects, the main complications of axillary lymph-nodal dissection for breast cancer treatment are reported. The role of surgical technique is particularly underlined and also the importance of proper management of wound and surgical drainage post-operatively are pointed out. Author describes, finally, the necessity of an...

If you are traveling along a space curve, the Cartesian i, j, and k coordinate system for representing the vectors describing your motion are not truly relevant to you. What is meaningful instead are the vectors representative of your forward direction (the unit tangent vector T), the direction in which your path is turning (the unit normal vector N), and the tendency of your motion to “twist” ...

As a particle moves along a smooth curve in the plane, turns as the curve bends. Since T is a unit vector, its length remains constant and only its direction changes as the particle moves along the curve. The rate at which T turns per unit of length along the curve is called the curvature (Figure 13.19). The traditional symbol for the curvature function is the Greek letter (“kappa”). k T = dr>d...

OVERVIEW When a body (or object) travels through space, the equations and that give the body’s coordinates as functions of time serve as parametric equations for the body’s motion and path. With vector notation, we can condense these into a single equation that gives the body’s position as a vector function of time. For an object moving in the xy-plane, the component function h(t) is zero for a...
