Automated laboratory light source for colorimetric research

Представлен лабораторный источник света, спектральный состав которого близок к стандартным осветителям серии D, состоящий из галогенной лампы с интерференционным фильтром и светодиодных излучателей, рабочие значения коррелированной цветовой температуры (CCT) которого могут варьироваться от 5000 до 6500 К. Описаны автоматизированная система управления световыми потоками на основе показателя GFC (Goodness Fitting Coefficient) и полученные характеристики источника.Presents laboratory light source, the spectral composition of which is similar to the standard lighting D-series consisting of halogen lamp with an interference filter and led emitters, operating values correlated color temperature (CCT) which can vary from 5000 to 6500 K. Described automated control system of light flows on the basis of average GFC (Goodness Fitting Coefficient) and the resulting characteristics of the source

Production of IFN-β during Listeria monocytogenes Infection Is Restricted to Monocyte/Macrophage Lineage

The family of type I interferons (IFN), which consists of several IFN-α and one IFN-β, are produced not only after stimulation by viruses, but also after infection with non-viral pathogens. In the course of bacterial infections, these cytokines could be beneficial or detrimental. IFN-β is the primary member of type I IFN that initiates a cascade of IFN-α production. Here we addressed the question which cells are responsible for IFN-β expression after infection with the intracellular pathogen Listeria monocytogenes by using a genetic approach. By means of newly established reporter mice, maximum of IFN-β expression was observed at 24 hours post infection in spleen and, surprisingly, 48 hours post infection in colonized cervical and inguinal lymph nodes. Colonization of lymph nodes was independent of the type I IFN signaling, as well as bacterial dose and strain. Using cell specific reporter function and conditional deletions we could define cells expressing LysM as the major IFN-β producers, with cells formerly defined as Tip-DCs being the highest. Neutrophilic granulocytes, dendritic cells and plasmacytoid dendritic cells did not significantly contribute to type I IFN production

Inkjet printing of organic light-emitting diodes based on alcohol-soluble polyfluorenes

Ink compositions for inkjet printing based on poly(9.9-dioctylfluorene) and its alcohol-soluble analog are created. Current–voltage, brightness–voltage, and spectral characteristics are compared for one- and twolayer polymer structures of organic light-emitting diodes. It is shown that the efficiency of the alcohol-soluble polyfluorene analog is higher compared to poly(9.9-dioctylfluorene), and the possibility of viscosity optimization is higher compared to aromatic chlorinated solvents

TO THE 95TH ANNIVERSARY OF THE DEPARTMENT OF PROPEDEUTICS OF INTERNAL DISEASES

Aim. To show the significance of the department of propedeutics of internal diseases in the structure of higher medical education and its role in the education of medical personnel in Kuban Medical University since its establishment. The article is devoted to the work of one of the oldest departments of Kuban State Medical University − department of propedeutics of internal diseases, − which was founded in 1922. The discipline taught in the department is one of the key stages of internal diseases studying. During the existence of the department, such prominent figures of medical science of the Kuban worked there: N.N. Niyibizi, K.M. Rutkevich, P.I. Budarin, K.A. Patsevich. The historical path of the department in many ways reflects the history of the University, the region and the country.Conclusion. The staff of the department has made a significant contribution to the development of healthcare of Krasnodar region and continues work on the training of doctors
