this study sougth to the effect of occ pulp fractionation on produced paper strength properties improvement. using a pressure screen, occ pulp was devided to tow distinct fractions of accept ratio (short fibers) and reject ratio (long fibers) in accordance with optimum condition of fractionation based on the previous studies. in the next stage, long fiber stream was refined and recombined with ...

The effect of the extracting procedures for potato pulp arabinogalactan were investigated on growth gut-microflora by in vitro experiments. Crude saccharides (CS) prepared 50 g dried suspended 1 L pure water. suspensions autoclaved at 1211C 2 h, and filtered a filter paper. filtrate concentrated around 1/4 rotary evaporator, aggregated 4× volume ethanol. Dialyzed (DS) to dialyzed CS dialysis me...

Dental Caries affects approximately 90% of the world's population. At present, the clinical treatment for dental caries is root canal therapy. This treatment results in loss of tooth sensitivity and vitality. Tissue engineering can potentially solve this problem by enabling regeneration of a functional pulp tissue. Dental pulp stem cells (DPSCs) have been shown to be an excellent source for pul...

1. Removal of the hypophysis in adult rats is followed by progressive atrophy of the spleen. At the end of 2 months the ratio of spleen weight to body weight is one-half the normal. The administration of hypophyseal emulsion repairs to a considerable degree the atrophy of the spleen in such animals. 2. Hypophysectomy completely inhibits the regeneration of splenic tissue after partial splenecto...

Pulp stones are usually found in the pulp chamber. Radiographically, they appear as radiopaque structures in the pulp chambers or root canals of individual teeth. Generalized pulp stones throughout the dentition are usually associated with systemic or genetic disorders of the dentine. This report presents an unusual case of a 13-year-old girl with generalized pulp stones with clinically normal ...

Considering the ease of isolation and high expansion potential of pulp stem/progenitor cells isolated from wisdom and primary teeth they have been implicated as the most reliable autologous cell source in dental tissue engineering. Meanwhile, different isolation methods have remarkable impacts on the expansion potential of adult stem cells. In enzymatic digestion method extracted teeth as denta...
