Cartilage Callus formation

Callus formation is slower in adults than in children, and in cortical bones than in cancellous bones.

Callus formation is induced from plant tissues after surface sterilization and plating onto in vitro tissue culture medium.

Callus formation may be evident but callus does not bridge across the fracture.

* Callus – A small area of skin, usually on the foot, that has become thick and hard from rubbing or pressure as a result of increased production of surface skin ( i. e., the topmost living cell layer ); the callus itself is the result of this overgrowth and is itself a thickened ' dead cell surface layer '.

He is married to Catherine ( née Callus ); the couple has three children.

Callus cells are not necessarily genetically homogeneous because a callus is often made from structural tissue, not individual cells.

Callus tissue is of particular use in micropropagation where it can be used to grow genetically identical copies of plants with desirable characteristics.

Callus is formed, but the bone fractures have not joined.

Callus tissue initiation has been described for many plant taxonomic divisions: Callus Nicotiana tabacum

Callus induction medium consists of agar and a mixture of macronutrients and micronutrients for the given cell type.

Callus can brown and die during culture, but the causes for callus browning are not well understood.

Working independently under the Bloodlust Software banner, Addis wrote NESticle, Genecyst and Callus ( and also a QSound player ), emulators of the Nintendo Entertainment System, Sega Genesis and CP System respectively, writing his own code for the MOS Technology 6502, Motorola 68000 and Zilog Z80.

Callus cultures are often broadly classified as being either compact or friable.

Callus can directly undergo direct organogenesis and / or embryogenesis where the cells will form an entirely new plant.

Due to the relative quality and speed of these emulators in contrast to other emulators of the time, NESticle, Genecyst and Callus became wildly popular amongst emulation enthusiasts.

Callus means a hardening of a certain object or substance.

Related to micelle formation is the technologically important ability of detergent actives to congregate at oil - water interfaces in such a manner that the polar ( or ionized ) end of the molecule is directed towards the aqueous phase and the hydrocarbon chain towards the oily phase.

Little is known of the synthetic mechanisms for formation of thyroglobulin.

A study of their activity on thyroglobulin has shown that thyroxine is not preferentially released and that the degradation proceeds stepwise with the formation of macromolecular intermediates ( Alpers, Petermann and Rall, 1956 ).

This warns the chartist that the formation in progress is quite likely to be a top.

In the first picture ( 9a ) the knife is just beginning to advance into the inclined surface which was left from the previous chip formation.

( Pp. 228-229 ) in any event, it is obvious that the anti-trust laws did not prevent the formation of some of the greatest financial empires the world has ever known, held together by some of the most fantastic ideas, all based on the fundamental notion that a corporation is an individual who can trade and exchange goods without control by the government ''.

Scientists assume that cholesterol ( from the Greek chole, meaning bile, and sterios, meaning solid ) is somehow necessary for the formation of brain cells, since it accounts for about 2% of the brain's total solid weight.

In simultaneous microsporogenesis, there is no wall formation until all four cell nuclei are present.

It is not concerned with the formation of molecules ( although much of the physics is identical ), nor does it examine atoms in a solid state as condensed matter.

In quantum mechanics, where all particle momenta are associated with waves, it is the formation of such a wave packet which localizes the wave, and thus the particle, in space.

Another example is the formation of hypusine in the translation initiation factor EIF5A, through modification of a lysine residue.

Immediately below this formation is the Bearpaw Shale, a marine formation representing a section of the Western Interior Seaway.

In the formation of an ordinary agate, it is probable that waters containing silica in solution — derived, perhaps, from the decomposition of some of the silicates in the lava itself — percolated through the rock and deposited a siliceous coating on the interior of the vapour-vesicles.

Cytochrome c is also released from mitochondria due to formation of a channel, the mitochondrial apoptosis-induced channel ( MAC ), in the outer mitochondrial membrane, and serves a regulatory function as it precedes morphological change associated with apoptosis.

HPV E6 and E7 are inhibitory proteins expressed by the human papillomavirus, HPV is responsible for the formation of the cervical tumor from which HeLa cells are derived.

Reproduction is thought to take place by formation of swarmer cells ( formerly referred to as " spores "), which may be flagellate.

For more complex alkynes, the Lindlar catalyst is widely recommended to avoid formation of the alkane, for example in the conversion of phenylacetylene to styrene.

The universal aqueous acid – base definition of the Arrhenius concept is described as the formation of water from a proton and hydroxide ions, or hydrogen ions and hydroxide ions from the dissociation of an acid and base in aqueous solution:

A standard solution to this problem is found in Zermelo's set theory, which does not allow the unrestricted formation of sets from arbitrary properties.

The movie is also credited as one of the events that inspired the formation of the " second era " Ku Klux Klan at Stone Mountain, Georgia in the same year.

The precise formation mechanism is not known for certain, but the most widely accepted hypothesis suggests that the edge of the Cathedral Formation reef became detached from the rest of the reef, slumping and being transported some distance — perhaps kilometers — away from the reef edge.
