Membrane traffic control by cytoskeletal and molecular machines

control of the optical properties of nanoparticles by laser fields

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...

Membrane Traffic: Controlling Membrane Fusion by Modifying NSF

Recent studies show that NSF, isolated over 15 years ago as a protein required for membrane fusion in vitro, can be reversibly inactivated by both S-nitrosylation and tyrosine phosphorylation. Different cell types use distinct post-translational modifications of NSF for localized regulation of membrane fusion.

Dual control of caveolar membrane traffic by microtubules and the actin cytoskeleton.

Live cell, time-lapse microscopy was used to study trafficking of caveolin-1-GFP in stably expressing CHO cells. Multiple cytological and biochemical tests verified that caveolin-1-GFP was a reliable marker for endogenous caveolin-1. At steady state, most caveolin-1-GFP was either at the cell surface associated with invaginated caveolae or near the centrosome in caveosomes. Live cell fluorescen...

Damage control by hypoxia-inhibited AK.

design of additional anti-LSC agents. Most interestingly, these compounds have been identified using a gene-expression signature derived from primitive AML CD34 ϩ cells to search through a broad spectrum of expression data obtained from several treatments performed on different nonhematopoi-etic cell types. This raises 2 important points. First, there may be no need to look at specific cancer s...
