TL;DR: A nonlinear least squares program (MULTI) for microcomputers was developed and the executions of MULTI are demonstrated for time courses of ampicillin and oxacillin in man.
Abstract: A nonlinear least squares program (MULTI) for microcomputers was developed. The program is written in BASIC programming language. Four algorithms, (1) Gauss-Newton method, (2) damping Gauss-Newton method, (3) modified Marquardt method and (4) simplex method, can be used for nonlinear curve fitting in MULTI. Up to five pharmacokinetic equations, which are voluntarily defined by the user, are simultaneously fitted to observed time courses. The executions of MULTI are demonstrated for time courses of ampicillin and oxacillin in man.

TL;DR: An overview of the current status of research on the prostanoid receptors is given and domains and amino acid residues conferring the specificities of ligand binding and signal transduction are being clarified.
Abstract: Prostanoids are the cyclooxygenase metabolites of arachidonic acid and include prostaglandin (PG) D2, PGE2, PGF2α, PGI2, and thromboxne A2. They are synthesized and released upon cell stimulation and act on cells in the vicinity of their synthesis to exert their actions. Receptors mediating the actions of prostanoids were recently identified and cloned. They are G protein-coupled receptors with seven transmembrane domains. There are eight types and subtypes of prostanoid receptors that are encoded by different genes but as a whole constitute a subfamily in the superfamily of the rhodopsin-type receptors. Each of the receptors was expressed in cultured cells, and its ligand-binding properties and signal transduction pathways were characterized. Moreover, domains and amino acid residues conferring the specificities of ligand binding and signal transduction are being clarified. Information also is accumulating as to the distribution of these receptors in the body. It is also becoming clear for some types of ...

TL;DR: New insights into the molecular architecture of tight junctions allow us to now discuss the structure and functions of this unique cell–cell adhesion apparatus in molecular terms.
Abstract: Tight junctions are one mode of cell-cell adhesion in epithelial and endothelial cellular sheets. They act as a primary barrier to the diffusion of solutes through the intercellular space, create a boundary between the apical and the basolateral plasma membrane domains, and recruit various cytoskeletal as well as signalling molecules at their cytoplasmic surface. New insights into the molecular architecture of tight junctions allow us to now discuss the structure and functions of this unique cell-cell adhesion apparatus in molecular terms.

TL;DR: In this article, a measure of manipulability of robotic mechanisms in positioning and orienting end-effectors has been proposed and the best postures of various types of manipulators are given, and a four degree-of-freedom finger is considered from the viewpoint of the measure.
Abstract: This paper discusses the manipulating ability of robotic mechanisms in positioning and orienting end-effectors and proposes a measure of manipulability. Some properties of this measure are obtained, the best postures of various types of manipulators are given, and a four-degree-of-freedom finger is considered from the viewpoint of the measure. The pos tures somewhat resemble those of human arms and fingers.

TL;DR: This new definition and grading system of postoperative pancreatic Fistula should lead to a more universally consistent evaluation of operative outcomes after pancreatic operation and will allow for a better comparison of techniques used to mitigate the rate and clinical impact of a pancreatic fistula.
