CONT

Mucopolysaccharidosis type II(MPS II; Hunter syndrome) is a rare X-linked recessive disease caused by deficiency of the lysosomal enzyme iduronate-2-sulphatase, leading to progressive accumulation of glycosaminoglycans in nearly all cell types, tissues and organs. Clinical manifestations include severe airway obstruction, skeletal deformities, cardiomyopathy and, in most patients, neurological decline.

DEF

[A pneumatic flotation machine consisting] of a long trough in the bottom of which is a longitudinal cylindrical rotor, covered with a porous medium, revolving slowly at about 15 revolutions per minute. The rotor is mounted at each end on hollow shafts extending out of the cell at each end through packing glands or through specially designed gland eliminators. Low-pressure air is introduced through the shaft at either end, or, for better control of aeration in various parts of the cell, the rotor may be divided into two sections and air introduced at both ends. The rotor is fitted with two longitudinal angle-iron scraper bars, which prevent settling and accumulation below it and thus protect the mat. The pulp enters at one end and is subjected to thorough aeration in passing through the machine. Froth overflows the sides, and tailings are discharged at the end by means of an adjustable weir overflow.

Record 4 2014-04-10

English

Subject field(s)
  • Microbiology and Parasitology
DEF

The regulation of gene expression in response to fluctuations in cell-population density.

CONT

The discovery that bacteria are able to communicate with each other changed our general perception of many single, simple organisms inhabiting our world. Instead of language, bacteria use signalling molecules which are released into the environment. As well as releasing the signalling molecules, bacteria are also able to measure the number(concentration) of the molecules within a population. Nowadays we use the term ’Quorum Sensing’(QS) to describe the phenomenon whereby the accumulation of signalling molecules enable a single cell to sense the number of bacteria(cell density). In the natural environment, there are many different bacteria living together which use various classes of signalling molecules. As they employ different languages they cannot necessarily talk to all other bacteria.

CONT

In the absence of sufficient alpha-galactosidase,... lipids, particularly globotriaosylceramide(GL-3; also known as Gb3, ceramide trihexoside, and CTH), accumulate progressively in the lysosomes of many cell types throughout the body. GL-3 accumulation in renal endothelial cells may play a role in renal failure.... Studies... demonstrate that [the] treatment results in significant GL-3 reduction from the vascular endothelium of the kidney, heart, and skin and from certain other cell types.

Record 8 2000-04-10

English

Subject field(s)
  • Biochemistry
DEF

Method for the large-scale purification of enzymes. The method involves placing a protein solution into a cell containing a number of semipermeable membranes. The pH of the solution is adjusted to the isoelectric point of the protein to be purified. A current is passed through the solution by two sloping electrodes. Because the required protein is at its isoelectric point it remains stationary in the electric field; all other proteins, being charged, will move either towards the cathode or the anode. This movement will cease when the migrating proteins meet the semipermeable membranes. The accumulation of protein at the membrane surface will cause an increase in density, thus it will move to the bottom of the cell.

Domaine(s)
  • Biochimie
DEF

Technique d'électrophorèse utilisée pour la séparation des protéines.
