The three component hydroxyletherification and hydroxylazidation reactions of (trifluoromethyl)alkenes are reported, providing various useful α-trifluoromethyl β-heteroatom substituted tertiary alcohols in high yields. The ipso-defluorooxylation of (trifluoromethyl)alkenes with oximes is completely inhibited. A pesticidal active compound could be synthesized with our method.

Background: Both air pollution and low socioeconomic status (SES) are associated with worse cognitive function. The extent to which low SES may compound the adverse effect of air pollution on cognitive function remains unclear.
Methods: 7,087 older adults aged 65 and above were included from the Chinese Longitudinal Healthy Longevity Survey (CLHLS) and followed up in 4 waves during 2008-2018.
Development of an eHealth Intervention Including Self-Management for Reducing Sedentary Time in the Transition to Retirement: Participatory Design Study.

Background: Having a great amount of sedentary time is common among older adults and increases with age. There is a strong need for tools to reduce sedentary time and promote adherence to reduced sedentary time, for which eHealth interventions have the potential to be useful. Interventions for reducing sedentary time in older adults have been found to be more effective when elements of self-management are included.

This study examines the acute effects of post-activation performance enhancement (PAPE) with different loads (84% and 60% 1-RM) and exercises (hip thrust; HT and glute bridge; GB) on sprint performance (SP) and horizontal force-velocity (HF-V) profile components in adolescent male soccer players. The participants were randomly assigned to three groups: hip thrust group (HTG; n = 13), glute bridge group (GBG; n = 13), and control group (CG; n = 14). Sprint tests at distances of 10, 20, and 30 m were conducted pre-PAPE and post-PAPE protocols with a 7 min rest period.

Developing an effective vaccine for haemorrhagic septicaemia (HS) in cattle and buffaloes is urgently needed. While preferred for their safety, achieving sufficient, cross-protective, and long-lasting immunity is still challenging when administering inactivated vaccines. This study aimed to assess the efficacy of four inactivating components comprising three inactivating agents: (1) Binary ethylenimine (BEI), (2) Formalin, (3) a combination of BEI and Formalin, and (4) Hydrogen peroxide (HO), in inactivating Pasteurella multocida to enhance HS vaccine potency.
