Talin is a large flexible rod-shaped protein that activates the integrin family of cell adhesion molecules and couples them to cytoskeletal actin. It exists in both globular and extended conformations, and an intramolecular interaction between the N-terminal F3 FERM subdomain and the C-terminal part of the talin rod contributes to an autoinhibited form of the molecule. Here, we report the solut...

Bambusoideae is a diverse subfamily that includes herbaceous (Olyreae) and woody (Arundinarieae and Bambuseae) bamboos. Species within Bambusae are particularly difficult to identify due to their monocarpic lifecycle and the often long durations between mass flowering events; whereas the herbaceous bamboos are pluricarpic, but often are found with no reproductive structures. The leaf blade anat...

The direction of rotation of the Escherichia coli flagellum is controlled by an assembly called the switch complex formed from multiple subunits of the proteins FliG, FliM, and FliN. Structurally, the switch complex corresponds to a drum-shaped feature at the bottom of the basal body, termed the C-ring. Stimulus-regulated reversals in flagellar motor rotation are the basis for directed movement...

Abstract Fluid blobs in an immiscible Newtonian fluid flowing a capillary tube with varying radius show highly nonlinear behavior. We consider here generalization of previously obtained results to non-Newtonian fluids. compute the yield pressure drop and mean flow rate two cases: (i) When single blob is injected, (ii) many are randomly injected into tube. find that effects emerge from non-unifo...

conclusions the intervention bundle prompted increased administration of psdivc and documentation. similar centres may benefit from an intervention to improve compliance. results sixty-four patients in group a underwent turbt prior to introduction of the intervention bundle. fifty-four patients had non-muscle invasive bladder cancer (nmibc), which would have been eligible for psdivc. fifteen (2...

horse shoe shaped lipoma of the upper extremity is a very rare entity. we present a case of 45 years old female who presented with painless progressive swelling over the distal forearm and tingling and numbness over the ulnar nerve territory. mri and surgical exploration showed a horse shoe shaped multilobulated lipoma encasing the distal ulna. the mass was excised in toto, and the sensory alte...

acute yew (taxus baccata) intoxication was induced in 7 adult sheep by oral administration of the plant materials at the dose of 2.5g/kg body weight. blood samples for hematology and serum biochemistry were collected before and after the induced intoxication.electrocardiography was performed using a base-apex lead. intoxicated animals displayed lethargy, depression, bradycardia and varying inte...

The two universally required components of the intracellular membrane fusion machinery, SNARE and SM (Sec1/Munc18-like) proteins, play complementary roles in fusion. Vesicular and target membrane-localized SNARE proteins zipper up into an alpha-helical bundle that pulls the two membranes tightly together to exert the force required for fusion. SM proteins, shaped like clasps, bind to trans-SNAR...
