A thermophilic, spore-forming rod isolated from hay compost in Korea was subjected to a taxonomic study. The micro-organism, designated strain SK-1(T), was identified as being aerobic, Gram-positive, motile and rod-shaped. Growth of the isolate was observed at 45-70 degrees C (optimum 60 degrees C) and pH 6.0-9.0 (optimum pH 7.5). The G+C content of the genomic DNA was 43.9 mol%. Chemotaxonomic...

Generalized knot groups Gn(K) were introduced first by Wada and Kelly independently. The classical knot group is the first one G1(K) in this series of finitely presented groups. For each natural number n, G1(K) is a subgroup of Gn(K) so the generalized knot groups can be thought of as extensions of the classical knot group. For the square knot SK and the granny knot GK, we have an isomorphism G...

Bacterial two-component systems (TCS) are key signal transduction networks regulating global responses to environmental change. Environmental signals may modulate the phosphorylation state of sensor kinases (SK). The phosphorylated SK transfers the phosphate to its cognate response regulator (RR), which causes physiological response to the signal. Frequently, the SK is bifunctional and, when un...

We evaluated the properties of recombinant staphylokinase in comparison with those of tissue-type plasminogen activator (t-PA) and streptokinase (SK). The presence of fibrin(ogen) fragment FCB-2 in the reaction mixture increased plasminogen activation by staphylokinase more than 20-fold. Such characteristics are similar to those of t-PA. On the other hand, SK was not affected by the presence of...

1 Problem mathematical formulation Let us consider a time-varying system described by k, θ, Sk, Zk, where k is the time index, θ is a vector of parameters, Sk is a random vector corresponding to the time-varying state at time k (with the corresponding realization denoted by sk), and Zk is a random vector corresponding to the observation process at time k (with the corresponding realization deno...

A wideband spectrometer of 500 MHz instantaneous bandwidth is described that includes an implementation of the Spectral Kurtosis (SK) algorithm for automatic radio frequency interference (RFI) detection. An SK spectrometer accumulates both power and power-squared, which are then used to develop the SK estimator. The SK spectrometer of the Korean Solar Radio Burst Locator (KSRBL) has a 2 GHz ins...

Furuno General Atomics, Photonics Division, 10240 Flanders Court, San Diego, California 92121 {naiel.askar, susan.lin, henry.pfister, gerald.rogerson, david.furuno}@gat.com Abstract. Spectral Keying (SK) is a novel UWB modulation scheme that combines properties of both Frequency Shift Keying and Pulse Position Modulation. An SK symbol...

UNLABELLED Atrial fibrillation (AF) is the most common sustained and most important arrhythmia in clinical practice. The mechanisms underlying AF initiation and maintenance are known to be complex and heterogeneous. The general understanding of the detailed molecular basis of AF is still incomplete. Recently, these is increasing evidence that small conductance calcium-activated potassium (SK) c...

This Review summarizes our current state of knowledge of the functional role of TRPC channels in health and disease, with particular emphasis on current advancements in the field. Additionally, this Review provides an up-to-date summary of SKF-96365 acting on TRPC channels, and discusses strategies to further investigate the potential of these channels for therapeutic intervention.

OBJECTIVE Heparin (HEP) is used in the post-thrombolytic state to prevent vessel reocclusion, thereby aiding myocardial salvage. Side effects limit its benefits, but besides anticoagulant activity HEP has diffuse actions that may be potentially beneficial to jeopardized reperfused myocardium. This study compares the effect of therapeutic doses of HEP and enoxaparin (ENOX), a low molecular weigh...
