TL;DR: In this paper, a hair dye composition with hardly any effects on human bodies and irritant smell even if ammonia is contained for providing hair dyeing treatment effects was obtained by adding an oily ingredient and surfactant to an alkaline agent containing ammonia and ammonium salt, water and an oxidation dye intermediate.
Abstract: PURPOSE:To obtain the title composition with hardly any effects on human bodies and irritant smell even if ammonia is contained for providing hair dyeing treatment effects, by adding an oily ingredient and surfactant to an alkaline agent containing ammonia and ammonium salt, water and oxidation dye intermediate. CONSTITUTION:A creamy hair dye composition containing an alkaline agent containing ammonia and an ammonium salt (especially preferably ammonium salts of hydrochloric acid, nitric acid, sulfuric acid, bisulfuric acid, phosphoric acid, acetic acid, oxalic acid and citric acid), water, an oxidation dye intermediate, an oily ingredient (especially preferably paraffin, liquid paraffin, bees wax, squalane, vaseline, lanolin, silicone derivative, higher fatty acid and higher alcohol) and a surfactant (e.g., alkyltrimethylammonium salt). The above- mentioned composition especially preferably contains 1-10wt.% aqueous ammonia in 28% concentration and 0.1-10wt.% ammonium salt and is adjusted to pH8-12.

TL;DR: The mammographic, sonographic, and MRI features of the early complications of breast augmentation by direct injection of liquid paraffin are presented and multiple cystic masses within the breast parenchymal and retroglandular fluid collections are revealed.
Abstract: OBJECTIVE. We present the mammographic, sonographic, and MRI features of the early complications of breast augmentation by direct injection of liquid paraffin. We also examined the imaging features in patients with paraffinoma, a later complication of these injections.CONCLUSION. Early complications of breast augmentation by direct injection of liquid paraffin differ in appearance from paraffinoma, which is a late complication of the same procedure. On mammography, early lesions appear as multiple circumscribed, noncalcified masses in the retroglandular and subpectoral regions. Sonography reveals multiple cystic masses within the breast parenchyma, retroglandular region, ipsilateral axilla, and pectoral muscle. MRI shows parenchymal and retroglandular fluid collections, which are hypointense on T1-weighted images and hyperintense on T2-weighted and fat-suppressed T2-weighted images, that do not enhance.

TL;DR: Smooth and solid WS2 submicrospheres were prepared by a laser irradiation induced fragmentation and morphological reshaping process using bulk-slice WS2 particles as targets in solution to show remarkably enhanced friction reduction and anti-wear properties in comparison with raw WS2 slices.

TL;DR: A modified oil-in-oil (o/o) emulsion solvent evaporation technique was adopted and microspheres with various particle sizes could be produced with a high 5-Fu entrapment efficiency and an ameliorated burst effect.
Abstract: A modified oil-in-oil (o/o) emulsion solvent evaporation technique was adopted to prepare 5-fluorouracil (5-Fu)-loaded poly (L-lactide) (PLLA) or its carbonate copolymer microspheres. The disperse phase was a drug:polymer solution using a solvent mixture of N, N-dimethylformamide (DMF) and acetonitrile and the continuous phase was liquid paraffin containing 1–10% (w/v) Span 80®. The effects of preparative parameters, such as the composition of the inner oil phase, drug:polymer ratio, polymer concentration and agitation rate, on 5-Fu entrapment efficiency and microsphere characteristics were investigated. By introducing 25% (v/v) DMF into the inner oil phase, microspheres with high drug entrapment efficiency and an ameliorated burst effect were achieved. Using this modified method, microspheres with various particle sizes could be produced with a high 5-Fu entrapment efficiency (about 80%). In vitro drug release tests showed a burst release of 5-Fu from PLLA microspheres, followed by a sustained release ov...
