Dehydrosoyasaponin-I (DHS-I) is a potent activator of high-conductance, calcium-activated potassium (maxi-K) channels. Interaction of DHS-I with maxi-K channels from bovine aortic smooth muscle was studied after incorporating single channels into planar lipid bilayers. Nanomolar amounts of intracellular DHS-I caused the appearance of discrete episodes of high channel open probability interrupte...

Background. Delayed loading is one of the concerns in implant patients. Immediate loading can solve the problem and make patients more satisfied. The present study aimed to compare the removal torque of maxi implants under different loading (immediate and delayed) patterns. Methods. This split-mouth experimental study included 2 dogs. Impressions were made and then all the premolars were extrac...

In this paper, we present a pseudo-collision attack on the compression function of all Twister variants (224,256,384,512) with complexity of about 2 compression function evaluations. Furthermore, we show how the compression function attack can be extended to construct collisions for Twister-512 with complexity of about 2. 1 Description of Twister The hash function Twister is an iterated hash fu...

Large-conductance chloride channels (maxi-Cl channels) were studied in cultured myoblasts (L6 rat muscle cell line); in excised (inside-out) and in cell attached membrane patches using a conventional patch clamp method. The incidence of maxi-Cl channels was substantially higher in proliferating myoballs, then in quiescent (bottom-attached) myoblasts (90% and 50% percent of examined cells, respe...
