Mutations in the skeletal muscle voltage-gated calcium channel (CaV1.1) have been associated with hypokalemic periodic paralysis, but how the pathogenesis of this disorder relates to the functional consequences of mutations was unclear. In this issue of the JCI, Wu and colleagues recapitulate the disease by generating a novel knock-in CaV1.1 mutant mouse and use this model to investigate the ce...
One of the puzzling clinical aspects of the metabolism of electrolytes is the genesis of symptoms and signs of potassium depletion and potassium intoxication (1-3). Precipitous flaccid paralysis, sensory disturbances and respiratory failure, altogether analogous to the sequence of events in familial periodic paralysis, may occur in these disturbances of potassium metabolism characterized by eit...
A neural network model that exhibits stochastic population bursting is studied by simulation. First return maps of interburst intervals exhibit recurrent unstable-periodic-orbit(UPO)-like trajectories similar to those found in experiments on hippocampal slices. Applications of various control methods and surrogate analysis for UPO detection also yield results similar to those of experiments. Ou...
This review of the primary familial periodic paralyses (PFPP) summarizes the pertinent clinical and laboratory findings of the three forms of this dis order. The review is intended to highlight diagnostic features of PFPP and to discuss current hypotheses regarding pathogenesis.
A simple and efficient interference method for fabricating highly symmetric two-dimensional (2-D) quasi-periodic structures (QPSs) is theoretically and experimentally demonstrated. With a three-beam interference technique, one can fabricate a periodic 2-D structure having sixfold symmetry. When this structure is multiduplicated into other specific orientations its combination results in a QPS w...
NEITZ, W. 0., BOUGHTON, F. & WALTERS, H. S., 1971. Laboratory investigation on the life-cycle of the Karoo paralysis tick (Ixodes rubicundus Neumann, 1904). Onderstepoort]. vet . Res., 38 (3) 215-224 (1971). Detailed data on the rearing of three groups of Ixodes rubicundus ticks at different temperature and humidity levels are presented in a series of tables and figures . The differences betwee...
The purpose of this study was to establish a sensitive and reliable method of diagnosing diaphragm paralysis by recording the diaphragm compound muscle action potential (CMAP) using a multipair oesophageal electrode and unilateral magnetic phrenic nerve stimulation. An oesophageal electrode catheter was designed containing six coils (1 cm wide and 3 cm apart), creating an array of four sequenti...
BACKGROUND Although the Horn of Africa region has successfully eliminated endemic poliovirus circulation, it remains at risk for reintroduction. International partners assisted Kenya in identifying gaps in the polio surveillance and routine immunization programs, and provided recommendations for improved surveillance and routine immunization during the health system decentralization process. ...
