Pulp cell

Yeasts tend to dominate the initial phase of the natural fermentation of cocoa pulp [1]. An isolate oiKluyveromyces marxianus (CCT 3172) was found to be the most pectinolytic of 12 yeast strains, resulting in degradation of pulp cell walls [1].

Radioactive Strontium. Osteonecrosis was reported for 2-day-old rats that were injected intraperitoneally with 2 mCi 90Sr/kg of body weight (Hopkins and Casarett 1972). In weanling rabbits, injection of 600 pCi 90Sr/kg resulted in increasing cell death of differentiating odontoblasts and pulp cells of immature teeth and disordered tooth structure (Rushton 1963). Mature teeth in the same animal, or teeth in adults injected at the age of 3 years or older, were not affected as severely.

In one study where Biodentine was placed over dentine, the elements calcium and silicon (in the form of silicate) were found to be transported into the dentine and also tag-like structures were formed [87]. This was similar to the behaviour of ProRoot MTA, despite the much more rapid hardening reaction of Biodentine. The release of calcium by Biodentine appeared to be well accepted by human fibroblast cells in cell culture studies [91]. The material stimulated the release of increased amounts of TGF-pi from pulp cells [92], which is probably associated with increased rates of cell differentiation and of mineralization in vivo.

When testing the viability of pulp cells in the presence of the new cement, the preosteoblast culture showed that GEMOSIL increased cell growth 25% from day 1 to day 5 but decreased cell growth 25% after the day 5. It was not clear by what mechanisms the material affects cell cycles and whether the cells in the preosteoblast ceU culture underwent apoptosis in... 

Fourth, on the antitumor activity) for the tumor cells, the hypophasic orange extract (PM3) and hypophasic apple extract (PM4) showed slightly their higher cytotoxicity against four the human tumor cells such as squamous cell carcinoma HSC-2, HSC-3, submandibular gland carcinoma HSG and human promyelocytic leukemic HL-60 cells when compared to their cytotoxic activity of three normal human oral cells such as gingival fibroblast HGF, pulp cell HPC and periodontal ligament fibroblast HPLF.

Over the past years there has been a strong development towards chitosan-based gels as functional restorative biomaterials. This has favored the inclusion of antioxidant-containing materials, antifungal and pain rehef medication into the chitosan molecule and then into the dental restorative material. However, to include any material before its cytotoxicity is known could be disastrous, as the tooth pulp cells could be temporarily or permanently damaged.

Grape berry consistency depends on skin and pulp cell wall thickness. Generally, table grape varieties produce plump, thin-skinned grapes (the pulp having thick cell walls), whereas winemaking varieties have tough skins and juicy pulp (pulp with thin cell walls).

The distribution of minerals in the grape berry is not insignificant and it has an impact on the composition of must at maturity. Potassium is essentially located in the pulp cell vacuoles, but the skin cells also sometimes contain significant amounts. 

B. cinerea uses little pectocellulosic cell wall residue for its development. As a result, the contaminated grape becomes rich in galacturonic acid derived from the degradation of pectic compounds. It prefers to assimilate glucose and fructose accumulated in the pulp cells, and 50% of the sugars are lost in the production of these noble rot wines.
