[The fighting for history of medicine].

Probl Sotsialnoi Gig Zdravookhranenniiai Istor Med 2021 Jul;29(4):998-1004

The Federal State Budget Scientific Institution "The N. A. Semashko National Research Institute of Public Health" of the Minobrnauka of Russia, 105064, Moscow, Russia,

The article considers issues of actual discussion about "death of history of medicine". For a long time, history of medicine was set out the task to substantiate triumph of one national model and tradition over another one and "to place the past at the service of the future". For example, Richard Horton, the editor-in-chief of The Lancet, believes that historians of medicine in no way respond to such problems of today as commercialization of medicine, drug abuse, paralysis in public health, catastrophic failures in patient care.

Modelling and parameter estimation of diethyl phthalate partitioning behaviour on glass and aluminum surfaces.

Chemosphere 2021 Jul 3;285:131414. Epub 2021 Jul 3.

UCL Institute for Sustainable Heritage, University College London, 14 Upper Woburn Place, London, WC1H 0NN, United Kingdom. Electronic address:

The knowledge of the partitioning behaviour of semi-volatile organic compounds (SVOCs), such as phthalates, between different materials and their surrounding air is of extreme importance for quantifying levels of human exposure to these compounds, which have been associated with adverse health effects. Phthalates' partitioning behaviour also represents a key property for modelling and assessing polymer degradation mechanisms associated with plasticiser loss. However, the characterisation of phthalates partitioning behaviour has been reported only for a limited number of compounds, mainly involving di-2-ethylhexyl phthalate (DEHP), di-isononyl phthalate (DINP) and di-isodecyl phtahalate (DIDP), while the characterisation of diethyl phthalate (DEP) partitioning has been overlooked.
