TL;DR: In this paper, the authors proposed a method to obtain the titled composition for ship, etc., stable for a long period and having excellent antifouling property by compounding a silicone rubber curable by chemical reaction, a petrolatum or a mixture of petrolatum and liquid paraffin and a silicone oil having low viscosity.
Abstract: PURPOSE: To obtain the titled composition for ship, etc., stable for a long period and having excellent antifouling property, by compounding a silicone rubber curable by chemical reaction, a petrolatum or a mixture of petrolatum and liquid paraffin and a silicone oil having low viscosity. CONSTITUTION: The objective composition can be produced by uniformly mixing (A) 100pts.(wt.) of a silicone rubber curable by chemical reaction (preferably a one-pack type rubber curable at normal temperature) with (B) preferably 5W80pts. of a petrolatum (preferably semisolid at normal temperature) or a mixture of petrolatum and liquid paraffin (the kinetic viscosity of the mixture is preferably 5,000W12,000cst at 25°C) and (C) preferably 60W20pts. of a low- viscosity silicone oil (methyl silicone oil and/or methylphenyl silicone oil preferably having a kinetic viscosity of 0.65W20cst at 25°C).

TL;DR: The percutaneous absorption and retention of salicylic acid and carbinoxamine from four oily vehicles were studied by employing a recirculation apparatus, and higher absorption rate constants were observed for damaged skin than intact skin.

TL;DR: The effects of oil on aphid settling and larviposition suggest that spraying crops with oil may not only reduce the incidence of aphid-transmitted viruses in them but may also diminish the population of potential vectors present in them.
Abstract: Experiments in the glasshouse have confirmed that spraying virus-source leaves or test plants with mineral oil (liquid paraffin) inhibits transmission of beet yellows virus (BYV) to sugar-beet by Myzus persicae (Sulz.). Spraying M. persicae with oil after feeding on BYV-infected leaves and before transfer to virus-free beet seedlings also inhibited their transmission of BYV. The appearance of systemic symptoms of BYV was not delayed by treatment of the test plants or the aphids with oil. The effects of oil on virus transmission were reflected in adverse effects of oil on the settling behaviour and larviposition of the vector on test plants. It is suggested that coating the stylets with oil inhibits the feeding of aphids in the phloem thereby decreasing the efficiency of BYV transmission. The effects of oil on aphid settling and larviposition suggest that spraying crops with oil may not only reduce the incidence of aphid-transmitted viruses in them but may also diminish the population of potential vectors present in them.

TL;DR: In this paper, the authors proposed a titled composition consisting of a sterol, emulsifying agent and dispersing agent, which can be used in many fields, e.g. prevention of water separation of margarine, etc., other humectant effect, sticking prevention effect, glossing effect, etc.
Abstract: PURPOSE: The titled composition consisting of a sterol, emulsifying agent and dispersing agent or the titled hydrous composition obtained by homogenizing the titled composition with water while stirring. CONSTITUTION: A sterol-containing composition obtained by dissolving 5W60wt% sterol, e.g. cholesterol, β-sitosterol, stigmasterol, etc., 2W80wt% emulsifying agent, e.g. water gel type; glycerol ester or sorbitan ester of a fatty acid, etc., which is a lipophilic emulsifying agent having <8 HLB; water-dispersible type; sorbitan ester or polyglycerol ester of a fatty acid, lecithin, etc., having ≥8 HLB and 0W80wt% dispersing agent, e.g. fat or oil which is liquid at ordinary temperature, medium-chain triglyceride, squalene, squalane or liquid paraffin, while heating. For a hydrous composition, 30W3,500pts.wt. water may by used in 100pts.wt. above-mentioned composition. The above-mentioned composition can be used in many fields, e.g. prevention of water separation of margarine, etc., other humectant effect, sticking prevention effect, glossing effect, etc. COPYRIGHT: (C)1987,JPO&Japio

TL;DR: Pooled human plasma (JHB 001) was employed as the inoculum, which was positive for HBsAg, HBeAg and DNA polymerase, and neutralized by dilution in 200 ml of saline solution to determine the susceptibility of HB virus to heat.
