Environmental factors, including abiotic conditions such as temperature, humidity, pH levels, light availability, and nutrient availability can influence population growth and distribution. Fluctuations (abrupt change) or extremes in these factors can limit population size and impact the ability of individua...
While paracellular permeability is elevated in the small intestine epithelium, reflecting its physiological role in nutrient absorption and establishment of food tolerance, the colonic epithelium exhibits limited paracellular permeability (Gitter et al., 2000). This helps the colonic epithelium to resist ...
Ser is implicated in a broad range of essential cellular functions such as antioxidant defense, one-carbon metabolism, and de novo nucleotide biosynthesis which make it a key nutrient supporting tumor cell proliferation [16]. Coherently, both SSP inhibition [17] and Ser dietary limitation [18, ...
The growth rate in a continuous culture does not depend on other factors such as nutrient concentration in the medium. Varying the culture medium concentration will increase or reduce cell abundance in the culture but the growth rate of the cells should remain constant. Continuous cultures can be...
