Root exudation contributes to soil carbon allocation and also to microbial C and energy supply, which subsequently impacts soil aggregation around roots. Biologically-driven soil structural formation is an important driver of soil fertility. Plant genetic determinants of exudation and more generally of factors promoting rhizosphere soil aggregation are largely unknown. Here, we characterized rh...
It is well understood that the extent of red blood cell (RBC) aggregation is determined by both plasmatic and cellular factors [10]. It is also clear that alterations of plasmatic and cellular factors may be related to separate disease processes [1]. For example, plasma composition may change (e.g., fibrinogen concentration increase) due to an acute phase response, thereby altering RBC aggregat...
Loss of protein homeostasis (proteostasis) is a common feature of aging and disease that is characterized by the appearance of nonnative protein aggregates in various tissues. Protein aggregation is routinely suppressed by the proteostasis network (PN), a collection of macromolecular machines that operate in diverse ways to maintain proteome integrity across subcellular compartments and between...
proteomics concerns itself with the characterization and function of all cellular proteins, the ultimate determinants of cellular function. mass spectrometry has emerged as the preferred method for in-depth characterization of the protein components of biological systems. using mass spectrometry, key insights into the composition, regulation and function of molecular complexes and pathways have...
The reversible aggregation of red blood cells (RBC) into linear and three-dimensional structures continues to be of basic science and clinical interest: RBC aggregation affects low shear blood viscosity and microvascular flow dynamics, and can be markedly enhanced in several clinical states. Until fairly recently, most research efforts were focused on relations between suspending medium composi...
Due to the non-polar nature of carbon nanotubes, their use in aqueous environments is limited. Therefore, auxiliary solvents such as dimethyl sulfoxide are used to study the interactions between the amyloid-β peptide and carbon nanotubes. In this work, the interaction of Aβ (1-42), the most effective peptide in the development of Alzheimer's disease, with the carbon nanotube was performed using...
Concave compositions were recently introduced by Andrews[3] in the study of orthogonal polynomials, see also Andrews [4]. A concave composition of even length 2m, is a sum of the form ∑ ai + ∑ bi such that a1 > a2 > · · · > am = bm < bm−1 < · · · < b1, where am ≥ 0, and all ai and bi are integers. Let CE(n) denote the set of concave compositions of even length that sum to n, and ce(n) be the ca...
The normal transmyocardial tissue hematocrit distribution (i.e., subepicardial greater than subendocardial) is known to be affected by red blood cell (RBC) aggregation. Prior studies employing the use of infused large macromolecules to increase erythrocyte aggregation are complicated by both increased plasma viscosity and dilution of plasma. Using a new technique to specifically alter the aggre...
