The classes of anomalous diffusions are classified as follows: α < 1: subdiffusion. This can happen due to crowding or walls. For example, a random walker in a crowded room, or in a maze, is able to move as usual for small random steps, but cannot take large random steps, creating subdiffusion.
Multi-wavelength anomalous diffraction (sometimes Multi-wavelength anomalous dispersion; abbreviated MAD) is a technique used in X-ray crystallography that facilitates the determination of the three-dimensional structure of biological macromolecules (e.g. DNA, drug receptors) via solution of the phase problem.
Amongst patients admitted to intensive care units (ICUs), hypoalbuminemia is specifically associated with ICU-acquired muscle weakness. [14] In chronic kidney disease , hypoalbuminemia is an indicator of frailty , which is itself associated with complications, mental distress , quality of life impairment, resource utilization, and mortality.
Single-wavelength anomalous diffraction (SAD) is a technique used in X-ray crystallography that facilitates the determination of the structure of proteins or other biological macromolecules by allowing the solution of the phase problem.
[43] [44] In those with low risk MDS (designated by an IPSS score less than 3.5), no disease specific treatment has been found to be helpful and treatment is focused on supportive care by maintaining blood counts. [36] Erythrostimulating agents such as darbepoetin alfa or erythropoietin may be used to raise the red blood cell count.
Fick's first law relates the diffusive flux to the gradient of the concentration. It postulates that the flux goes from regions of high concentration to regions of low concentration, with a magnitude that is proportional to the concentration gradient (spatial derivative), or in simplistic terms the concept that a solute will move from a region of high concentration to a region of low ...
In hematology, plasma cell dyscrasias (also termed plasma cell disorders and plasma cell proliferative diseases) are a spectrum of progressively more severe monoclonal gammopathies in which a clone or multiple clones of pre-malignant or malignant plasma cells (sometimes in association with lymphoplasmacytoid cells or B lymphocytes) over-produce and secrete into the blood stream a myeloma ...
The version of R2 encoded by RRM2B is induced by TP53, and is required for normal DNA repair and mtDNA synthesis in non-proliferating cells. The other form of R2 is expressed only in dividing cells. [14] The DGUOK gene encodes for mitochondrial deoxyguanosine kinase (dGK), which catalyzes the phosphorylation of deoxyribonucleosides into ...
