The in vitro osteoclastic degradation of nacre

Biomaterials, 2007
Osteoclast activity was studied on nacre, the mother of pearl (MOP) in order to assess the plasticity of bone resorbing cells and their capacity to adapt to a biomineralized material with a different organic and mineral composition from that of its natural substrate, bone.

In vitro degradation of silk fibroin

Biomaterials, 2005
A significant need exists for long-term degradable biomaterials which can slowly and predictably transfer a load-bearing burden to developing biological tissue. In this study Bombyx mori silk fibroin yarns were incubated in 1mg/ml Protease XIV at 37 degrees C to create an in vitro model system of proteolytic degradation.

The in vitro degradation of the herbicide bromoxynil

Canadian Journal of Microbiology, 1974
The in vitro degradation of the herbicide bromoxynil at the 25 ppm level by a flexibacterium, strain BR4, was investigated. The degradation was monitored using gas-chromatographic and spectrophotometric analytical procedures. Breakdown was rapid with only 5% of the original herbicide remaining after 5 weeks.

In vitro quantitative study of the degradation of endomorphins

Peptides, 2002
The catabolism of the endomorphins was investigated in detail. The endomorphins were degraded relatively slowly in the rat brain homogenate (t1/2(endomorphin-1)=4.94 min; t1/2(endomorphin-2)=3.81 min). The inhibition of metalloproteases and aminopeptidases stabilised the endomorphins to the greatest extent.

Degradation of rat liver metallothioneins in vitro

Biochimica et Biophysica Acta (BBA) - General Subjects, 1978
The degradation of zinc and cadmium-induced hepatic metallothionineins was investigated in vitro. Both zinc-thionein and cadmium-thionein were labeled in vivo with [35S]cystine. The labeled proteins were isolated and purified by gel filtration and DEAE-ion exchange chromatography. Purified zinc[35S]thionein and cadmium-[35S]thionein were incubated with

The enzymatic degradation of polymers in vitro

Journal of Biomedical Materials Research, 1987
AbstractSpecimens of 14C‐labeled poly(ethylene terephthalate), nylon 66, and poly(methyl methacrylate) have been synthesized and exposed, in vitro, to a number of enzyme solutions. Poly(ethylene terephthalate) was found to be affected by esterase and papain, although in different ways, but not by trypsin or chymotrypsin.

In Vitro Model of Cartilage Degradation

2010
This 14-day model of cartilage breakdown involves stimulation of bovine nasal cartilage with a combination of interleukin-1 and oncostatin M. Media is harvested on days 7 and 14 and the conditioned media and remaining cartilage at day 14 assayed for the levels of proteoglycan and collagen fragments using biochemical assays.

Degradation and Aggregation of Human Calcitonin In Vitro

Pharmaceutical Research, 1999
To investigate the degradation of human calcitonin (hCT) by enzymes or mucosa from different gastrointestinal (GI) compartments and evaluate the stabilization effect of a synthetic ionizable copolymer on the stability of hCT in an aqueous solution. These data are a prerequisite for the development of a hydrogel based colon-specific hCT delivery system ...

Degradation of collagen suture in vitro and in vivo

Biomaterials, 1992
In vitro and in vivo degradation of collagen suture was investigated focussing on the change in the mechanical properties and weight. The in vitro hydrolysis was carried out for catguts using collagenase (pH 7.4) and pepsin (pH 1.6), simulating the in vivo environments.

In vitro degradation of zearalenone by Bacillus subtilis

Biotechnology Letters, 2010
Zearalenone (ZEN) is a non-steroidal estrogen produced by many Fusarium species in cereals and other plants, and is frequently implicated in safety of foods and feeds. A ZEN-degrading microorganism has been isolated and identified as a Bacillus subtilis subspecies.
