BACKGROUND Vein-graft harvesting with the use of endoscopy (endoscopic harvesting) is a technique that is widely used to reduce postoperative wound complications after coronary-artery bypass grafting (CABG), but the long-term effects on the rate of vein-graft failure and on clinical outcomes are unknown. METHODS We studied the outcomes in patients who underwent endoscopic harvesting (1753 pat...
A simulation study demonstrates how the nonlinear optical response of the Fenna-Matthews-Olson photosynthetic light-harvesting complex may be explored by a sequence of laser pulses specifically designed to probe the correlated dynamics of double excitations. Cross peaks in the 2D correlation plots of the spectra reveal projections of the double-exciton wavefunctions onto a basis of direct produ...
Multienzyme complexes and multifunctional proteins may confer a kinetic advantage by channelling reaction intermediates between consecutive enzymes and reducing the transient time for the establishment of steady states. A general means for quantitatively assessing the contribution of channelling to the reduction of pool size and transient time is presented. Restrictions to the kinetic advantage...
Many of the photosynthetic genes are conserved among all higher plants, indicating that there is strong selective pressure to maintain the genes of each protein. However, mutants of these genes often lack visible growth phenotypes, suggesting that they are important only under certain conditions or have overlapping functions. To assess the importance of specific genes encoding the light-harvest...
میوه خرما از میوه هایی است که بسته به رقم می تواند هم به صورت تازه خوری مصرف شود هم به صورت میوه با رطوبت کم که به مدت طولانی می توان آن را نگهداری کرد. محصول خرما پس از برداشت از درخت به دلیل این که به صورت سنتی و غیر بهداشتی برداشت می شود، غالباً در زمان جمع آوری، حمل و نقل و بسته بندی دچار ضایعات متعددی می شود. چندین تکنولوژی نگهداری، شامل انبار سرد، تابش uv، بسته بندی با اتمسفر تغییر یافته، ...
Replacement of the usual harvesting sugarcane method (burning field before harvesting) by green harvesting method could be the most important factor contributing to the ecological balance and stable sugarcane production in the Khuzestan region. To evaluate the green harvesting sugarcane method and its effects on the agronomic and physiological characteristics of sugarcane cultivars, a field exp...
