A technique for mass-labeling was developed to study sex pheromone biosynthesis in the red-banded leafroller moth,Argyrotaenia velutinana. With this technique, the pheromone components and all fatty acyl groups in the pheromone gland were analyzed for incorporation of label in the same analytic ran with gas chromatography-mass spectrometry, using chemical ionization and selected ion monitoring GC-SIM-CI-MS. Sex pheromone glands were incubated with fatty acids or triacylglycerols labeled with at least three deuterium atoms or carbon atoms. The results of these incubations support an interpretation in which hexadecanoate is chain shortened to tetradecanoate, which is desaturated to produce E - and Z tetradecenoate precursors for the sex pheromone components E - and Z tetradecenyl acetate. Labeled E - and Z tetradecenoyl groups in synthetic triacylglycerols were not incorporated into the sex pheromone components, perhaps indicating that this lipid class is not a donor of the immediate fatty acyl precursors in sex pheromone biosynthesis.

The so-called "rough sex gone wrong" defence will be outlawed in new domestic abuse legislation, a justice minister has told MPs. Alex Chalk said it was "unconscionable" that the defence can be used in court to justify or excuse the death of a woman "simply because she consented". He said it would be made "crystal clear" in the Domestic Abuse Bill that it was not acceptable. Jess Phillips, Labour's shadow minister for domestic violence and safeguarding, spoke on an amendment proposed by Labour MP Harriet Harman and Conservative MP Mark Garnier to the legislation, to prevent lawyers from using the defence, but withdrew it following assurances from Mr Chalk. The campaign group We Can't Consent To This, which wants the defence outlawed, said the minister's response was "a big step forward". Campaigners want to make it the expectation that murder charges are brought against those suspected of killing a person during sex. As it stands, if someone kills another person during sexual activity they could be charged with manslaughter alone.

In the s, San Francisco, and the American West generally, was a hotbed of anti-Chinese sentiment. Spurred by racism, exacerbated by the economic uncertainty of an ongoing recession, the xenophobia manifested itself in discriminatory legislation and violent physical intimidation against Chinese men and women. Anti-miscegenation laws and restrictive policies that prohibited Chinese women from immigrating to the U. Motivated by their Christian faith, a group of white women set out to offer the immigrant women a path out of slavery and sex trafficking and, ideally, into what they viewed as good Christian marriages.
