In recent years, the introduction and systematic application of new diagnostic techniques has enormously increased the opportunities to investigate magnetic fields of chemically peculiar (CP) stars. To approach the problem of modelling these fields, in previous papers we set up a theory aimed at describing the magnetic configuration due to the superposition of a dipole with an arbitrary quadrup...

F or approaching the truth about the clinical phenomenon of tinnitus from more and more possible aspects, it is important in the sense of the old Aristotelean systematics of scientific thinking to choose various and alternating directions for regarding the phenomenon. Therefore, today I am also choosing a biochemical angle of view. Our model of good and bad hearing, ear noise or tinnitus , is p...

This paper presents the catalogue and the method of determination of averaged quadratic effective magnetic fields B e for 596 main sequence and giant stars. The catalogue is based on measurements of the stellar effective (or mean longitudinal) magnetic field strengths B e , which were compiled from the existing literature. We analysed the properties of 352 chemically peculiar A and B stars in t...

Background Mammalian cells are used extensively in the production of recombinant proteins, and of monoclonal antibodies (MAbs) in particular. The trend towards avoiding animal-derived components in biopharmaceutical production processes has led to the extensive use of nonanimal origin hydrolysates such as plant hydrolysates or yeast hydrolysates. The source of hydrolysates affects cell growth a...

Oleanolic acid and ursolic acid are triterpenoid compounds that exist widely in food, medicinal herbs and other plants. This review summarizes the pharmacological studies on these two triterpenoids. Both oleanolic acid and ursolic acid are effective in protecting against chemically induced liver injury in laboratory animals. Oleanolic acid has been marketed in China as an oral drug for human li...

The Pedersen-Freed theory for chemically induced dynamic spin polarization CIDN(E)P is generalized to include the effects of anisotropic reactivities and anisotropic exchange interactions on the radical-pair mechanism. Detailed results are given for the simple case in which only one radical exhibits anisotropy that is approximated by a cosine distribution, and the rotational and translational m...

Neural mechanisms underlying the onset and maintenance of epileptic seizures involve alterations in inhibitory and/or excitatory neurotransmitter pathways. Thus, the prospecting of novel molecules from natural products that target both inhibition and excitation systems has deserved interest in the rational design of new anticonvulsants. We isolated the alkaloids (+)-erythravine and (+)-11-α-hyd...
