Secretory activity of gastroduodenal zone before and after cholecystectomia

Вивчено функціональні особливості секреторної активності гастродуоденальної зони до та піс­ля холецистектомії. Встановлено пригнічення ферментовидільної функції шлунка у хворих із постхолецистектомічним синдромом. З’ясовано, що наявність дуодено-гастрального рефлюксу свідчить про дуоденостаз і недостатність замикальної функції пілоричного сфінктера. У хворих видалення жовчного міхура призводить до аритмії циркадних і ультрадіадних ритмів усієї травної системи й, у тому числі, до порушень активності секреторних залоз шлунка.Изучены функциональные особенности секреторной активности гастродуоденальной зоны до и пис¬ля холецистэктомии. Установлено угнетение ферментовыводящей функции желудка у больных с постхолецистэктомический синдромом. Выяснено, что наличие дуодено- гастральной рефлюкса свидетельствует о дуоденостаз и недостаточность замыкательной функции пилорического сфинктера. У больных удаление желчного пузыря приводит к аритмии циркадных и ультрадиадних ритмов всей пищеварительной системы и, в том числе, к нарушениям активности секреторных желез желудка.Functional features of the gastroduodenal zone secretory activity before and after cholecystectomia were studied. The oppression of the stomach enzymatic secretion in patients with postcholecystectomia syndrome was established. The presence of duodeno-gastral reflux testifies to the duodenostasis and incompetence of closing function of the pyloric sphincter. Cholecystectomia entails the arrhythmia of circadian and ultradian rhythms of the whole digestive apparatus, including the derangements of the stomach secretory glands

Influence of the left rotation vortical impulsive magnetic field on the bioelectric activity of rats’ hypothalamus in physiologycal and stress conditions

Досліджено динаміку спектральної композиції електричної активності егротропної та трофо­тропної зон гіпоталамуса щурів за умов тривалого стресу (21 тиждень) і дії лівонапрямленого вихрового імпульсного магнітного поля (МП). Виявлено, що ефекти впливу вихрового МП залежать від вихідного стану дослідженої мозкової структури та терміну впливу. За фізіологічних умов під впливом МП у спек­тральній композиції електрогіпоталамограми спостерігається синхронізація, яка виражається у підвищенні потужності тета-ритму. Під комбінованим впливом стресу та МП спостерігається формування двофазної електрогіпоталамограми у вигляді послідовної зміни явища десинхронізації синхронізацією електричної активності за рахунок представленості високочастотних компонентів. Исследована динамика спектральной композиции электрической активности егротропнои и трофо¬тропнои зон гипоталамуса крыс в условиях длительного стресса (21 неделя) и действия ливонапрямленого вихревого импульсного магнитного поля (МП). Выявлено, что эффекты воздействия вихревого МП зависят от исходного состояния исследованной мозговой структуры и срока действия. При физиологических условиях под влиянием МП в спек¬тральний композиции електрогипоталамограмы наблюдается синхронизация, которая выражается в повышении мощности тета-ритма. Под комбинированным воздействием стресса и МП наблюдается формирование двухфазной електрогипоталамограмы в виде последовательной смены явления десинхронизации синхронизацией электрической активности за счет представленности высокочастотных компонентовThe dynamics of spectral composition of electric activity in the trophotropic and ergotropic areas of the rat hypothalamus during long time stress (21 week) and action of the left directed vortical impulsive magnetic field (MF) were investigated. It was discovered that effects of vortical MF influence depend both on the initial state of studied cerebral structure and the period of influence. Under physiological condition the MP influence leads to synchronization in spectral composition of electrohypotalamogramme (EGtG) that was expressed by theta-rhythm increasing. The formation of diphasic EGtG as a successive replacement of the desynchronization by synchronization of electric activity due to high-frequency components was observed under the combined influence of stress and MF

LEETECH facility as a flexible source of low energy electrons

A new versatile facility LEETECH for detector R&D, tests and calibration is designed and constructed. It uses electrons produced by the photoinjector PHIL at LAL, Orsay and provides a powerful tool for wide range R&D studies of different detector concepts delivering "mono-chromatic" samples of low energy electrons with adjustable energy and intensity. Among other innovative instrumentation techniques, LEETECH will be used for testing various gaseous tracking detectors and studying new Micromegas/InGrid concept which has very promising characteristics of spatial resolution and can be a good candidate for particle tracking and identification. In this paper the importance and expected characteristics of such facility based on detailed simulation studies are addressed

Challenges in QCD matter physics --The scientific programme of the Compressed Baryonic Matter experiment at FAIR

Substantial experimental and theoretical efforts worldwide are devoted to explore the phase diagram of strongly interacting matter. At LHC and top RHIC energies, QCD matter is studied at very high temperatures and nearly vanishing net-baryon densities. There is evidence that a Quark-Gluon-Plasma (QGP) was created at experiments at RHIC and LHC. The transition from the QGP back to the hadron gas is found to be a smooth cross over. For larger net-baryon densities and lower temperatures, it is expected that the QCD phase diagram exhibits a rich structure, such as a first-order phase transition between hadronic and partonic matter which terminates in a critical point, or exotic phases like quarkyonic matter. The discovery of these landmarks would be a breakthrough in our understanding of the strong interaction and is therefore in the focus of various high-energy heavy-ion research programs. The Compressed Baryonic Matter (CBM) experiment at FAIR will play a unique role in the exploration of the QCD phase diagram in the region of high net-baryon densities, because it is designed to run at unprecedented interaction rates. High-rate operation is the key prerequisite for high-precision measurements of multi-differential observables and of rare diagnostic probes which are sensitive to the dense phase of the nuclear fireball. The goal of the CBM experiment at SIS100 (sNN= 2.7--4.9 GeV) is to discover fundamental properties of QCD matter: the phase structure at large baryon-chemical potentials (μB> 500 MeV), effects of chiral symmetry, and the equation of state at high density as it is expected to occur in the core of neutron stars. In this article, we review the motivation for and the physics programme of CBM, including activities before the start of data taking in 2024, in the context of the worldwide efforts to explore high-density QCD matter
