CYTOKINESIS IN VERTEBRATE CELLS INITIATES BY CONTRACTION OF AN EQUATORIAL ACTOMYOSIN NETWORK COMPOSED OF RANDOMLY ORIENTED FILAMENTS

Cytokinesis in vertebrate cells initiates by contraction of an equatorial actomyosin network composed of randomly oriented filaments

The actomyosin ring generates force to ingress the cytokinetic cleavage furrow in animal cells, yet its Drum Cooling Fan filament organization and the mechanism of contractility is not well understood.We quantified actin filament order in human cells using fluorescence polarization microscopy and found that cleavage furrow ingression initiates by c

Systolic anterior motion of mitral valve following resection of subaortic membrane and intracardiac repair of tetralogy of fallot

Drum Cooling Fan Systolic anterior motion (SAM) of the mitral valve is commonly observed in patients with hypertrophic obstructive cardiomyopathy and in few patients after mitral valve repair or aortic valve replacement.It may cause significant hemodynamic instability due to left ventricular outflow tract (LVOT) obstruction and resulting mitral reg

High-energy-density electron beam from interaction of two successive laser pulses with subcritical-density plasma

It is shown by particle-in-cell simulations that a narrow electron beam with high energy and charge density can be generated in a subcritical-density plasma by two Mat Insert consecutive laser pulses.Although the first laser pulse dissipates rapidly, the second pulse can propagate for a long distance in the thin wake channel created by the first pu

Detection of multiple etiologies and comparison and investigation of pathological changes in small and large intestine lesions of dogs

Aim: This study was conducted for the purposes of investigating pathological changes in intestines of dogs, detecting prevalence of Dollhouses them and determining their role in being the cause of death.Materials and Methods: The intestines of 100 dead stray dogs were examined in macroscopic, histopathologic, microbiologic, and parasitic aspects.Im
