In biology the term 'condensation' is used much more broadly and can also refer to liquid–liquid phase separation to form colloidal emulsions or liquid crystals within cells, and liquid–solid phase separation to form gels, [1] sols, or suspensions within cells as well as liquid-to-solid phase transitions such as DNA condensation during ...
In human tissue culture cells, the two condensin complexes are regulated differently during the mitotic cell cycle (Figure 4). [ 55 ] [ 56 ] Condensin II is present within the cell nucleus during interphase and participates in an early stage of chromosome condensation within the prophase nucleus.
English: Scanning electron microscopy reveals that sister-chromatid pairs first condense into single rod-like structures during prophase. As mitosis proceeds, chromatid arms are gradually resolved and become almost completely distinct by the end of metaphase.
The human body and even its individual body fluids may be conceptually divided into various fluid compartments, which, although not literally anatomic compartments, do represent a real division in terms of how portions of the body's water, solutes, and suspended elements are segregated. The two main fluid compartments are the intracellular and ...
Homologous recombination is the principal mechanism of DNA repair acting during meiosis. From the leptotene to early pachytene stages of meiosis exogenous damage triggered the massive presence of gamma H2AX (which forms when DNA double-strand breaks appear), H2AX was present throughout the nucleus, and this was associated with DNA repair ...
President Joe Biden signed the Social Security Fairness Act into law Sunday afternoon, marking what is expected to be one of the last major pieces of legislation of his presidency. Prior to ...

The purpose of microneedling for hair loss is to stimulate growth factors in the dermal papilla, or the stem cells in your hair follicles. This encouraged them to activate and start growing more hair.
