TL;DR: In this paper, four kinds of polytetrafluoroethylene (PTFE)-based composite, pure PTFE, PTFB+30vol.%Cu, PBF+, PBF, and PBF+30v.%Ni composite, were prepared and examined using an MHK-500 ring-block wear test.

TL;DR: TPEt has potent chemopreventive efficacy and significant antilipidperoxidative effect, in DMBA-induced oral carcinogenesis, in hamster buccal pouch carcinoma.
Abstract: Objectives: To investigate the chemopreventive potential and antilipidperoxidative effects of ethanolic root extract of Tephrosia purpurea (Linn.) Pers. (TpEt) on 7,12-dimethylbenz(a)anthracene (DMBA)- induced hamster buccal pouch carcinoma. Materials and Methods: Oral squamous cell carcinoma was developed in the buccal pouch of Syrian golden hamsters, by painting with 0.5% DMBA in liquid paraffin, thrice a week, for 14 weeks. The tumor incidence, volume and burden were determined. Oral administration of TpEt at a dose of 300 mg/kg, b.w., to DMBA (on alternate days for 14 weeks)- painted animals significantly prevented the incidence, volume and burden of the tumor. Results: TpEt showed potent antilipidperoxidative effect, as well as enhanced the antioxidant status in DMBA- painted animals. Conclusion: TpEt has potent chemopreventive efficacy and significant antilipidperoxidative effect, in DMBA-induced oral carcinogenesis. Further studies are needed to isolate and characterize the bioactive principle.

TL;DR: Results indicate the beneficial role of phenylbutazone, ibuprofen and fraction "A" of gum-guggul in experimental arthritis.
Abstract: In the present investigation a method of induction of experimental arthritis in animals was modified to provide a better model replica of human arthritis. Inflammatory syndrome, resembling rheumatoid arthritis in man, was induced in the right hock joint of albino rabbits by intra-articular injection of the killed mycobacterial adjuvant in liquid paraffin. Development of this arthritic syndrome was studied from a period of five months with and without drugs. Anti-inflammatory agents such as phenylbutazone, ibuprofen and fraction "A" of gum-guggual from Commiphora mukkul were administered orally at a daily dose of 100, 100 and 500 mg/kg, respectively, for a period of five months. All three drugs decreased the thickness of the joint swelling during the course of drug treatment. These results indicate the beneficial role of phenylbutazone, ibuprofen and fraction "A" of gum-guggul in experimental arthritis.

TL;DR: In this article, a high-pressure wet-type jet mill and a motionless mixer called the Ramond Supermixer were used to generate submicrometer emulsions.
Abstract: Submicrometer emulsions were generated by a high-pressure wet-type jet mill and a motionless mixer called the Ramond Supermixer. Kerosene and liquid paraffin were used as the dispersed phase, aqueous sucrose and poly(ethylene glycol) solutions of PEG 400 to PEG 20000 were used as the continuous phase, and sodium dodecyl sulfate was used as a surfactant. The droplet size distribution, the Sauter mean diameter (d32), and the geometric standard deviation of the droplet size distribution (σg) were investigated under various combinations of the operating variables. The analysis of time-scale parameters contributed to an understanding of droplet deformation and possible re-coalescence. The relationship between the maximum droplet diameter and d32 was determined to be a function of the ratio of the viscosity of the dispersed phase to the viscosity of the continuous phase (K). Empirical correlations were constructed for d32 and σg, and a larger similarity was determined to exist within the correlations, irrespect...
