Define the term diffusion. What is its importance? Describe the clinical presentations of pneumonia. What is an infarct? Define the numerical aperture of a microscope. Explain how to make 100 ml of a 10% solution of a concentrated beet extract (liquid). Explain density-dependent and density-in...
Define diffusion. Define the term silent mutation. Define classification. Define gnathostomes. Give a definition of osmosis. What is diffusion? Give a definition. Define the term frequency as it relates to genetics. Define science and biology. Define Atelectasis. Identify key words that define wha...
Here we combine diffusion limitation with the geometric sizes of extracellular enzymes, polymer particles, monomers, and bacterial cells to derive testable relationships of SOM kinetic parameters, including (1) maximum reaction rates and (2) binding half saturation constants (also known as substrate ...
A septin diffusion barrier at the base of the primary cilium maintains ciliary membrane protein distribution. Science 329, 436–439 (2010). 50. Tong, C. K. et al. Axonal control of the adult neural stem cell niche. Cell Stem Cell 14, 500–511 (2014). 51. Mirzadeh, Z., Doetsch, F...
RNA splicing shapes the gene regulatory programs that underlie various physiological and disease processes. Here, we present the SCASL (single-cell clustering based on alternative splicing landscapes) method for interrogating the heterogeneity of RNA spl
In sum, a whole new field has emerged, devoted to the investigation of the molecular mechanisms, the cell biology, the physiological and pathological implications of contact sites. While it is now obvious that such appositions are central to the structure and function of any eukaryotic cell and...
Solute diffusion and interactions in cross-linked poly(ethylene glycol) hydrogels studied by Fluorescence Correlation Spectroscopy Controlled diffusion and release of soluble molecules is one of the key challenges in developing three-dimensional (3D) scaffolds for tissue engineering an...

Similarly, cells migrate into adjacent vacant lattice nodes with equal probability to simulate random walks and cell diffusion (Brownian motion). The ability of the tumor cell to proliferate and move is temporarily lost due to contact inhibition, and this quiescent state is abandoned as soon as ...
Although peptide neurotransmitters are traditionally viewed as slow-acting neuromodulators released from perisynaptic sites in response to Ca2+ diffusion during high-frequency bursting15, their release has been demonstrated to occur over a wide range of firing frequencies16,17,18. Peptidergic large dense...
