BACKGROUND This study aimed to evaluate and compare the efficacy of three desensitizing dentifrices on dentinal hypersensitivity (DH) and salivary biochemical characteristics. MATERIALS AND METHODS A randomized, parallel arm, triple-blinded, clinical trial was conducted over a period of 12 weeks, with a total of three visits: baseline, 6 weeks, and 12 weeks. Calcium sodium phosphosilicate, po...

Histochemical methods have been devised Lo demonstrate certain metabolic activities of cells. By these techniques certain structures in a particular tissue are made to stand out in contrast to the other constituents. We have applied the methods for demonstrating alkaline and acid phosphatase activity to the study of the skin in leprosy. Pearse (5) has pointed out that these methods depend on in...

Conventional process of nitrating phenolic compounds involves the use excess corrosive reagents that impose environmental threats. Rapid and environmentally friendly microwave-assisted nitration phenol has been employed to limit nitric acid sulfuric acid. In this study, is reacted calcium nitrate acetic acid, which served as agents. The solution irradiated under microwave complete process. This...

A 30 year old man had an acute anterolateral myocardial infarction following which he developed unstable angina requiring percutaneous transluminal coronary angioplasty. He subsequently developed further angina with recurrence of coronary artery lesions that were reversed by intracoronary nitrate. A diagnosis of prinzmetal (vasospastic) angina was made and this had been the apparent cause of hi...

The production of thermostable extracellular protease by Bacillus stearothermophilus F1 was influenced by the composition of culture medium. Peptone iv derived from soybean was the best organic compound for enzyme production. Sodium nitrate, ammonium salts and amino acids as sole nitrogen sources interfered with protease formation. The addition of most carbon sources to the peptone medium faile...

Abstract This study was done to identify some characteristics of chemical, physical, and the concentrations nutritious salts nitrate, phosphates in groundwater on six wells selected district Al-Shinafiyah during period from June August 2022. The results obtained for temperatures were almost equal between with rates ranging 23-25 C°. pH values ranged (7-7.23). Electrical conductivity (4250-6350)...
