TL;DR: In this paper, Dibenzylidene sorbitol (DBS) was chosen as an in situ forming nucleating agent to study ultrahigh molecular weight polyethylene (UHMWPE)/liquid paraffin (LP) physical gel and complex phase separation.
Abstract: Dibenzylidene sorbitol (DBS) was chosen as an in situ forming nucleating agent to study ultrahigh molecular weight polyethylene (UHMWPE)/liquid paraffin (LP) physical gel and complex phase separation. The experimental results indicated that DBS self-assembled into fibrils first and the solution became a physical gel before liquid–liquid phase separation (LLPS) and crystallization during thermally induced phase separation (TIPS) of UHMWPE/LP/DBS solution. The temperature of DBS self-assembly and viscoelasticity of UHMWPE/LP/DBS gel show a strong dependence on DBS concentration, temperature, and time. By controlling the relative quenching depth and annealing time, the grow rate of the characteristic length showed a crossover from LLPS to crystallization, which was further justified by differential scanning calorimetry (DSC) and wide-angle X-ray diffraction (WAXD). With decreasing temperature further, crystallization occurred with the aid of DBS fibrils. Those interactions were affected mutually, showed comp...

TL;DR: The results showed that both hypertrophy and hyperplasia occur in turpentine-treated hamster cheek pouch epithelium, showing that at the histological level stereological techniques can be employed to detect quantitative similarities and differences between normal and pathological epithelia.

TL;DR: In this article, the composite material includes substrate and boundary layer, the substrate material powder after being ball ground and mixed is compounded with PVA solution as adhesive, liquid paraffin as lubricant and glycerine as plasticizer.
Abstract: The composite material includes substrate and boundary layer, the material for the substrate includes Si3N4, baking assistant and flexibilizer, and the material for the boundary layer is BN. The substrate material powder after being ball ground and mixed is compounded with PVA solution as adhesive, liquid paraffin as lubricant and glycerine as plasticizer. The ceramic blank with formed boundary layer is placed into graphite mold to exhaust glue and sintered so as to result in the silicon nitride-based composite material of the present invention. The composite material of the present inventionhas high tenacity, high temperature resistance and good mechanical impact resistance and other advantages.

TL;DR: The chemopreventive potential of andrographolide in DMBA-induced hamster buccal pouch carcinogenesis is demonstrated, which is probably due to its antioxidant potential as well as modulating effect on xenobiotic metabolising enzymes during DMBA -induced oral carcinogenesis.
Abstract: The aim of the study was to investigate the chemopreventive potential of andrographolide in 7,12-dimethylbenz(a) anthracene (DMBA)-induced hamster buccal pouch carcinogenesis. Oral tumors developed in the buccal pouch of golden Syrian hamsters at a 100% incidence on painting with 0.5% DMBA in liquid paraffin three times a week for 14 weeks. Marked abnormalities in the status of detoxification enzymes, lipid perxodiation and antioxidants were noticed in hamsters treated with DMBA alone. Oral administration of andrographolide at a dose of 50 mg/ kg bw to hamsters treated with DMBA not only completely prevented the tumor formation but also restored the status of the above mentioned biomarkers. The present study thus demonstrates the chemopreventive potential of andrographolide in DMBA-induced hamster buccal pouch carcinogenesis, which is probably due to its antioxidant potential as well as modulating effect on xenobiotic metabolising enzymes during DMBA-induced oral carcinogenesis.
