Disruption of growth

In most cases, artificial destratification is carried out throughout the summer. However, work in the Lund Tubes in Blelham Tarn suggests that intermittent destratification could provide further enhancement to this method of control by creating an unstable environment. This instability causes disruption of growth patterns of the algal community and, consequently, no species becomes dominant.

The first reports on rickets in infants originate from Soranus of Ephesus, a Greek physician, who practiced in Alexandria and subsequently in Rome at about 100 AD. As we know nowadays, rickets predominant cause is a deficiency or impaired metabolism of Vitamin D. Partiorlarly in malnourished children, this results in the disruption of growth and softening and deformation of the bones, as a consequence of insufficient mineralisation of the coUagen matrix (Fig. 7.37). 

Cisplatin, Pt (NH3)2Cl2, is a chemotherapeutic agent that disrupts die growth of DNA. If die current cost of Pt is 1118.0/troy ounce (1 troy oz = 31.10 g), how many grams of cisplatin can you make with three thousand dollars worth of platinum How many pounds ... 

State of deviation of plasma pH (systemic acidosis) or tissue extracellular pH (tissue or local acidosis) from normal (ca. pH 7.4) towards lower values. Deviation of 0.1 pH units is significant. Systemic acidosis can be caused by lung or kidney failure. Local acidosis can be the consequence of injury, inflammation, or tumor growth, due to disruption of blood supply. Local acidosis is normally associated with hypoxia. 

Paget s disease is a chronic bone disorder characterized by abnormal bone remodeling. The disease disrupts the growth of new bone tissue causing the bone to thicken and become soft. This weakens the bone, which increases susceptibility of fracture even with slight trauma or collapse of the bone (eg, the vertebrae).
