Moscow doctor A.G. Dreytser – author of "The Notes of an Ambulance physician"
No full textWe have attempted to present the scientific biography of Alexander Grigorievich Dreytser, the author of "The Notes of an Ambulance physician" – a popular documentary work on the life of Moscow and Muscovites during the Great Patriotic War. We have reconstructed the main points of life and activities of A.G. Dreytser and discovered a number of facts in his biography related to his studying at Strasbourg University (1911–1914) and Imperial Moscow University (1915–1917), participation in the First World War and activities in 1918–1941. The analysis of the materials stored in the State Archive of the Russian Federation, the Central State Archive of the City of Moscow, the Russian State Archive of Literature and Art, as well as the personal archive of the Dreytser family, allowed us to clarify many points related to Dreytser's life and activities during the time prior to the creation of The Notes. This article is based upon the results of a comparative analysis of the texts of The Notes and A.G. Dreytser's Ph.D. dissertation "The Material on the Question of Sudden Death: According to the Data of Morgues, Moscow City Emergency Stations and the Department of Clinical Examination of the Central Polyclinic of the People's Commissariat for Health of the USSR". This article considers the hypothesis of the unity of the events that took place in Moscow during the Great Patriotic War and were described in the dissertation and The Notes. More complete historical and biographical data on A.G. Dreytser allowed us to prove the documentary nature of The Notes, expand the scope of known facts about the organisation of medicine during the war and clarify some circumstances of the history of Russian medicine as a whole
A modified Rayleigh conjecture for static problems
No full textAbstractA modified Rayleigh conjecture (MRC) in scattering theory was proposed and justified by the author [A.G. Ramm, Modified Rayleigh conjecture and applications, J. Phys. A 35 (2002) L357–L361]. The MRC allows one to develop efficient numerical algorithms for solving boundary-value problems. It gives an error estimate for solutions. In this paper the MRC is formulated and proved for static problems

Pathological conditions, such as Parkinson's disease and attention deficit
hyperactivity disorder, have been linked to alterations of specific dopamine (DA)
pathways. However, since exogenous DA does not cross the blood-brain barrier, DA
levels can be modulated e.g. by DA precursors or DA reuptake blockers. Hereby
histochemical, analytical and behavioral evidence shows that a galactosylated
form of DA (GAL-DA) carries DA into the brain, thus modulating activity and
nonselective attention in rats. To this aim adult male rats of the Naples
high-excitability (NHE) and random bred controls (NRB) lines were given a single
i.p. injection of GAL-DA (10 or 100 mg/kg). Three hours later the behavior was
videotaped and analyzed for horizontal activity, orienting frequency and scanning
duration. The dose of 100 mglkg of GAL-DA reduced by 25% the horizontal activity
in NHE rats, mainly in the first part of the testing period. No effect was
observed on orienting frequency or on scanning duration. However, GAL-DA 100
mg/kg was associated with longer rearing episodes in the second part of the
testing period in NHE rats. In parallel experiments histochemistry with a
galactose-specific lectin showed 10% increase in galactose residues into the
striatum between 0.5 and 3.0 h. To quantify the level of GAL-DA, its metabolite
DA-succinate and DA in the prefrontal cortex, neostriatum, and cerebellum, rats
were killed 2.0 h after the injection of prodrug. Mass high performance liquid
chromatography (HPLC) was used for analysis of GAL-DA and DA succinate whereas
electrochemical HPLC for DA. Both HPLC techniques demonstrate that GAL-DA carries
and releases DA into the brain. Specifically 100 mg/kg of GAL-DA increased DA
level in the striatum in the NHE rats only. Moreover, DA in the mesencephalon
(MES) was correlated positively with striatal and prefrontal cortex DA in NHE
rats. In contrast DA in the MES was negatively correlated with striatal DA in
NRB. GAL-DA disrupted these correlations in both rat lines. Thus, this new DA
prodrug may modify DA neurotransmission and might have a potential clinical
application.

The influence of steady blowing and roughness on transitional separated boundary layers
No full textThis paper presents the results of a study between two types of forcing, namely steady blowing and a tripwire, on the control of laminar separated boundary layers. The analysis focuses on the differences in the transition process between these two types of forcing. This effect will be studied using direct numerical simulation. The main differences consists in the coherent structures formed during transition and the overall kinetic energy growth
