    Reaction of Trichloro(o-phenylenedioxy)phosphorane with Four-Coordinate Phosphorus Esters

    Get PDF
    Reactions of trialkyl phosphates and dialkyl alkenylphosphonates with trichloro(o-phenylenedioxy)phosphorane result in selective replacement of one alkoxy group on the phosphorus by a chlorine atom. Alkylphosphonates react with trichloro(o-phenylenedioxy)phosphorane to give alkyl alkylphosphonochloridates as the major products and small amounts of alkylphosphonic dichlorides

    Trichloro(o-phenylenedioxy)phosphorane reacts with 1,2-alkadienylphosphonates with selective replacement of the alkoxy group in the phosphinoyl moiety, yielding the corresponding 1,2-alkadienylchlorophosphonates and o-phenylene chlorophosphate

    Reactions of Phosphorylsulfenyl Chlorides with 2H-1,2,3-Diazaphospholes

    Get PDF
    Formation of a quasiphosphonium salt in reaction of phosphorylsulfenyl chlorides with 1,2,3-diazaphospholes was established by dynamic 31P NMR spectroscopy. The salt is formed by addition of 2 mol of phosphorylsulfenyl chloride to the Οƒ2Ξ»3P=C endocyclic fragment by the 1,1- and 1,2-addition schemes. Decomposition of the salt yields mainly O,O-dialkyl phosphothiochloridate and, to a lesser extent, dialkyl phosphochloridate

    Synthesis of Ξ²-aminophosphonates and study of their acid-base properties and phase distribution in water-organic solvent systems

    Get PDF
    New and previously known Ξ²-aminoethylphosphonates were synthesized by addition of primary and secondary amines to vinylphosphonates, and their IR and NMR spectra were examined. Diethyl 2-diethyl-aminoethylphosphonate and diethyl 2-morpholinoethylphosphonate were found to be stronger bases than the corresponding aminomethylphosphonates, but all these are weaker bases than their precursors, nonphosphorylated amines. Distribution constants of Ξ²-aminophosphonates between water and some organic solvents were determined and compared with those of their Ξ±-amino homologs. Β© 2005 Pleiades Publishing, Inc

    The article is dedicated to Professor L.L. Fofanof’s scientific activity. He headed the faculty therapeutic clinic of Kazan Imperial University in 1915-1920. Being a student L.L. Fofanov was interested in pathological anatomy and physiology. His dissertation Β«To physiology of n. depressorisΒ» was dedicated to studying the vasomotor center. During his visit in Germany he worked a lot. In Charite together with Professor His he studied gout and its treatment with Radium emanation. In Halle clinic under Professor Schmidt’s supervision he studied assimilation of starch in normal and pathological digestion. L.L. Fofanov also made a contribution to tuberculosis treatment: with professor V.F. Orlovskiy he studied treatment of tuberculosis with simulated pneumothorax. In his research professor L.L. Fofanov paid great attention to the issues of pathogenesis and pathogenetic substantiation of the clinical manifestation and treatment. During the World War I and Civil War he fought against typhus epidemies: he saw patients, gave lectures, studied the features of myocardial involvement. He died in 1920 from typhus

    The paper presents a comparative analysis of the incidence Russian and Serbian citizens arrived in the receiving department TSGKB β„– 6 Ekaterinburg. Revealed that the local population Leninsky district of Yekaterinburg was therapeutic pathology of hereditary nature, as well as stress-related, adverse environmental conditions and bad habits. The citizens of Serbia have a pathology associated with hypothermia, physical activities, violation of the regime and the composition of food. Emergency services in the emergency department has the same efficiently and as residents of Ekaterinburg, as well as foreign nationals.Π’ Ρ€Π°Π±ΠΎΡ‚Π΅ прСдставлСны Π΄Π°Π½Π½Ρ‹Π΅ ΡΡ€Π°Π²Π½ΠΈΡ‚Π΅Π»ΡŒΠ½ΠΎΠ³ΠΎ Π°Π½Π°Π»ΠΈΠ·Π° заболСваСмости российских ΠΈ сСрбских Π³Ρ€Π°ΠΆΠ΄Π°Π½, ΠΏΠΎΡΡ‚ΡƒΠΏΠΈΠ²ΡˆΠΈΡ… Π² ΠΏΡ€ΠΈΠ΅ΠΌΠ½ΠΎΠ΅ ΠΎΡ‚Π΄Π΅Π»Π΅Π½ΠΈΠ΅ Π¦Π“ΠšΠ‘ β„– 6 Π³.

    Diagnostic Algorithm for Joint Pain in Patients with Inflammatory Bowel Disorders

    Aim. An algorithm development for joint pain differential diagnosis in patients with inflammatory bowel disorders (IBD) and its validation in clinical practice.Materials and methods. A total of 349 IBD patients hospitalised for gastroenterological complaints at the Chelyabinsk Regional Clinical Hospital during 2017–2020 have been examined.Results. Upon survey, 97 (27.8%) IBD patients complained of joint pain. Ulcerative colitis (UC) predominated (79 patients; 81.4%), Crohn’s disease (CD) had a 18.6% incidence. In survey, 27% UC and 32.1% CD patients reported joint pain (p = 0.26). Among IBD patients, 52.6% had mechanical, and 47.4% β€” inflammatory pain. The inflammatory back pain (IBP) rate in survey cohort was 23.7%. Use of a diagnostic algorithm allowed concomitant rheumatic disease detection in 7 (7.2%) patients from the IBD–joint pain cohort: 2 patients were diagnosed with psoriatic spondyloarthritis, 2 β€” rheumatoid arthritis, 1 β€” gout and 2 β€” with ankylosing spondylitis. IBD-associated arthritis was diagnosed in 41 (42.3%) cases, osteoarthritis β€” in 38 (39.2%) IBD patients with joint pain, arthralgia with no objective inflammation, impaired joint function or lesions in X-ray and/or ultrasound β€” in 13 (13.4%) patients.Conclusion. Joint pain complaints are common in IBD patients and require a multispecialty rheumatologists-involving approach to proceed with differential diagnosis and opting for treatment tactics. A clinically verified algorithm coupled with laboratory tests and instrumental imaging facilitates diagnosis and optimal therapy selection in IBD patients with complaints of joint pain

    The paper describes a rare clinical case of ankylosing spondylitis (AS) with concurrent with Takayasu arteritis (AT). It considers the common immunopathogenetic mechanisms that can link these two diseases. Taking into account that there may be common triggering factors for AS and AT, it is necessary to make an examination to diagnose AT when a patient with AS is found to have fever, an increase in the indicators of acute phase inflammation, and the objective signs of cardiovascular disease characteristic of large-vessel vasculitis.ΠŸΡ€Π΅Π΄ΡΡ‚Π°Π²Π»Π΅Π½ΠΎ клиничСскоС наблюдСниС Ρ€Π΅Π΄ΠΊΠΎΠ³ΠΎ сочСтания Π°Π½ΠΊΠΈΠ»ΠΎΠ·ΠΈΡ€ΡƒΡŽΡ‰Π΅Π³ΠΎ спондилита (АБ) с Π°Ρ€Ρ‚Π΅Ρ€ΠΈΠΈΡ‚ΠΎΠΌ Вакаясу (АВ).
