زمینه و هدف: با توجه به اینکه هنوز علت اصلی مرگ و میر در اکثر نقاط دنیا بیماریهای قلبی- عروقی است، پیشگیری و درمان این بیماریها با توجه به مکانیسم های جدید ارائه شده قابل توجه است. این پروژه با تکیه بر مکانیسم جدید بیماریهای عروقی مبنی بر یک بیماری التهابی در صدد یافتن ترکیبات خاص در پیشگیری از تشکیل و پیشرفت رگه های چربی (fatty streak) در آترواسکلروز بوده است. روش مطالعه: در یک مطالعه مداخله ...
A number of studies were conducted to determine whether motion-streaks assist motion extraction, and whether a purely motion-based model could account for any observed facilitation. A 3-frame global-motion stimulus was used. Signal dots were manipulated in order to control the strength of the motion-streak. In the long-streak condition, the same dots carried the global-motion signal over succes...
We have used a computer simulation system to examine formation of the chick primitive streak and to test the proposal (Wei and Mikawa Development 127 (2000) 87) that oriented cell division could account for primitive streak elongation. We find that this proposal is inadequate to explain elongation of the streak. In contrast, a correctly patterned model streak can be generated if two putative me...
[1] Slope streaks on Mars represent a currently active geological process. Various theories for slope streak formation have suggested that slope streaks form by disturbing only a thin surface veneer, or by staining of the surface, preserving pre-existing topography within the streak. Theories also vary as to whether the formation mechanism requires the presence of water or another liquid. We pr...
Dietary Antioxidants Inhibit Development of Fatty Streak Lesions in the LDL Receptor–Deficient Mouse
We have investigated the patterns of tissue flow underlying the formation of the primitive streak in the chick embryo. Analysis of time-lapse sequences of brightfield images to extract the tissue velocity field and of fluorescence images of small groups of DiI-labelled cells have shown that epiblast cells move in two large-scale counter-rotating streams, which merge at the site of streak format...
