Self-organizing & stochastic behaviors during the regeneration of hair stem cells [PDF]
, 2011 Stem cells cycle through active and quiescent states. Large populations of stem cells in an organ may cycle randomly or in a coordinated manner. Although stem cell cycling within single hair follicles has been studied, less is known about regenerative ...

Transcriptional activators and activation mechanisms [PDF]
Protein & Cell, 2007 Transcriptional activators are required to turn on the expression of genes in a eukaryotic cell. Activators bound to the enhancer can facilitate either the recruitment of RNA polymerase II to the promoter or its elongation. This article examines a few selected issues in understanding activator functions and activation mechanisms.

Preparation and Oxidation Resistance of Mo-Si-B Coating on Nb-Si Based Alloy Surface
Cailiao gongcheng, 2018 Mo-Si-B coating was prepared on Nb-Si alloys to improve the high-temperature oxidation. The influence of the halide activators (NaF and AlF3) on Si-B co-depositing to obtain Mo-Si-B coating on Nb-Si alloys was analyzed by thermochemical calculations. The

Active colloidal molecules in activity gradients [PDF]
Physical Review E, 2022 We consider a rigid assembly of two active Brownian particles, forming an active colloidal dimer, in a gradient of activity. We show analytically that depending on the relative orientation of the two particles the active dimer accumulates in regions of either high or low activity, corresponding to, respectively, chemotaxis and antichemotaxis.

Journal of Enzyme Inhibition and Medicinal Chemistry, 2017 Identifying possible new biological activities of psychoactive substances belonging to various chemical classes may lead to a better understanding of their mode of action and side effects. We report here that amines structurally related to amphetamine, a

Activation of β- and γ-carbonic anhydrases from pathogenic bacteria with tripeptides
Journal of Enzyme Inhibition and Medicinal Chemistry, 2018 Six tripeptides incorporating acidic amino acid residues were prepared for investigation as activators of β- and γ-carbonic anhydrases (CAs, EC 4.2.1.1) from the pathogenic bacteria Vibrio cholerae, Mycobacterium tuberculosis, and Burkholderia ...

Extensive reuse of soda-lime waste glass in fly ash-based geopolymers [PDF]
, 2018 The possibility of extensive incorporation of soda-lime waste glass in the synthesis of fly ash-based geopolymers was investigated. Using waste glass as silica supplier avoids the use of water glass solution as chemical activator.
