Identification and structural elucidation of ozonation transformation products of estrone

BACKGROUND Quantitative methods for the analysis of contaminants of emerging concern (CECs) are abundant in the scientific literature. However, there are few reports on systematic methods of identification and structural identification of transformation products. For this reason, a new method based on high-resolution mass spectrometry and differential analysis was developed in order to facilita...

compactifications and representations of transformation semigroups

this thesis deals essentially (but not from all aspects) with the extension of the notion of semigroup compactification and the construction of a general theory of semitopological nonaffine (affine) transformation semigroup compactifications. it determines those compactification which are universal with respect to some algebric or topological properties. as an application of the theory, it is i...

isolation and structural elucidation of natural products in euphorbia erythradenia

Structural elucidation of rabeprazole sodium photodegradation products.

Rabeprazole sodium is a proton pump inhibitor, used in acid-related disorders, like peptic ulcers and gastroesophageal reflux. It is known to be an acid-labile drug, however, few data about its stability under other factors are available. The aim of this work was to study the photodegradation of rabeprazole, to determine its kinetics and to elucidate the structures of the main degradation produ...

functional study of p0 proteins of two cereal yellow dwarf viruses (cydv-rpv and cydv-rps) and identification of their cellular partner

نقش سرکوبگری پروتئین p0 در دو پولروویروس کوتولگی زردی غلات cydv-rpv) و (cydv-rps، متفاوت در شدت بیماریزایی، مورد مطالعه قرار گرفت. نتایج نشان داد که هر دو پروتئین p0 p0cy-rpv) و (p0cy-rps قادر به سرکوب خاموشی آر ان ای ایجاد شده توسط ترادف های تراژن سنس و تکرار معکوس در n. benthamiana هستند. نشان داده شد که هر دو پروتئین p0 می توانند تخریب پروتئین argonaute-1 را تسهیل کنند. علاوه بر این، تمایل م...
