in order to study the effect of rootstock, scion and some methods of grafting and budding to achieve the best methods of grafting in pomegranate, split factorial experiment was conducted in a completely randomized design in march 2013 in greenhouse at the agricultural college of vali-e-asr university of rafsanjan. factors included rootstock, scion, and methods of grafting and time of grafting. ...

BACKGROUND Colorectal carcinogenesis is believed to be a multi-stage process that originates with a localized adenoma, which linearly progresses to an intra-mucosal carcinoma, to an invasive lesion, and finally to metastatic cancer. This progression model is supported by tissue culture and animal model studies, but it is difficult to reconcile with several well-established observations, princip...

In this paper, we consider the evolutionary competition between budding and lytic viral release strategies, using a delay differential equation model with distributed delay. When antibody is not established, the dynamics of competition depends on the respective basic reproductive ratios of the two viruses. If the basic reproductive ratio of budding virus is greater than that of lytic virus and ...

Internalization of biotin-S-S-125I-transferrin (125I-BSST) into semiintact A431 cells were assessed by two different criteria which have allowed us to distinguish partial reactions in the complex overall process of receptor-mediated endocytosis. Early events resulting in the sequestration of ligand into deeply invaginated coated pits were measured by inaccessibility of 125I-BSST to exogenously ...

Membrane budding is a key step in vesicular transport, multivesicular body biogenesis, and enveloped virus release. These events range from those that are primarily protein driven, such as the formation of coated vesicles, to those that are primarily lipid driven, such as microdomain-dependent biogenesis of multivesicular bodies. Other types of budding reside in the middle of this spectrum, inc...

Introducing overseas talents become an important way to solve shortage talent resources. policy introduction in our country different times characteristics historical periods.

Abstract Background The world today is faced with the humongous challenge of removing numerous plastic wastes in our environment. Efforts removal or remediation these materials from ecosystem are presently at budding stage. Some researchers have shown that certain bacterial enzymes ability to hydrolyze and further degrade compounds. In this study, PET hydrolase enzyme polyvinylchloride, polyure...

BACKGROUND Cells release extracellular vesicles (ECVs) that can influence differentiation, modulate the immune response, promote coagulation, and induce metastasis. Many ECVs form by budding outwards from the plasma membrane, but the molecules that regulate budding are unknown. In ECVs, the outer leaflet of the membrane bilayer contains aminophospholipids that are normally sequestered to the in...
