Published: December 2021

ABSTRACT

Background:
The COVID-19 pandemic has led to hundreds of thousands of deaths worldwide.

Aims:
Being a novel viral disease, we sought to evaluate the knowledge and practice of doctors and nurses in a tertiary hospital regarding the disease.

Subjects and Methods:
Using a self-administered questionnaire, respondents were asked questions on the cause, clinical features, and prevention of COVID-19.

Results:
We studied 409 respondents (238 doctors and 171 nurses) with a mean age of 34 ± 7 years and a median length of experience of five (IQR 2-9) years. The mean knowledge score was 9.6 ± 1.2 out of a maximum of 12 points with 337 (82.4%) respondents having good knowledge. The majority of respondents (62.8%) had not been trained on infection prevention and control since the outbreak of the pandemic. Only 95 (23.2%) had seen COVID-19 Standard Operating Procedures (SOP) displayed in the hospital. The use of the personal protective equipment (PPE) kit comprising the N-95 mask, face shield, gown, and shoes was seen by 194 (47.4%) respondents in recent times. A total of 397 (97.0%) respondents felt they were at an increased risk of contracting COVID-19 relative to the general populace. Measures taken to prevent COVID-19 included: wearing of face mask (68.7%), hand gloves (78.2%), frequent use of hand sanitizers (84.1%), frequent hand washing (84.8%), the daily wash of uniforms and ward coats (44.5%), daily cleaning of footwear (31.7%), and avoidance of taking home clothing and footwear worn in the hospital (54.2%).

Conclusion:
Despite having good knowledge of transmission and clinical features of SARS-CoV 2, the utilization of protective measures by HCW in this study is unsatisfactory.

ABSTRACT

Background:
Gastrointestinal tract stromal tumors (GIST) are the most common mesenchymal tumors in the gastrointestinal tract (GIS). GISTs may cause significant morbidity and mortality rates.

Aim:
In this study, it was aimed to evaluate 10 years of gastric GIST cases followed in our hospital, and to analyze the prognostic factors.

Subjects and Methods:
In this single-center retrospective study, a total of 64 patients who were operated between May 2010 and May 2020 due to gastric GIST tumor were reviewed. Clinical and pathological features, risk classifications, overall survival (OS) and disease-free survival (DFS) were evaluated.

Results:
According to the risk classification, 18.8% of the patients were in the high-risk group. The overall 5-year OS and DFS rates were 85.7%. The mean OS of the patients was 47.9 SD36.2 months, and the duration of DFS was 45.5 months. Patients with a 5-year OS rate above 5 cm in diameter (P = 0.024), with a mitotic index above 5/50 high power field (HPF) (P = 0.038), and those with a high-risk group (P = 0.011) were significantly lower than the other group. In the correlation analysis, it was found that tumor diameter correlated significantly with OS (P = 0.034; r = -0.317). Tumor diameter and mitotic index were found to be inversely correlated with DFS duration (P = 0.004; r = -0.425 and P = 0.035; r = -0.316, respectively).

Conclusion:
Our findings showed that in gastric GIST cases, as the primary tumor diameter and mitotic index increase, correlate with survival rates and the mean overall and disease-free survival times decrease.

SPECTRAL PROPERTIES OF A BENZOTHIAZOLE DYE MODIFIED WITH POLYETHYLENE GLYCOL
Authors: Maskevich A. A. 
Published: December 2021

The spectral properties of a new benzothiazole dye modified with polyethylene glycol have been investigated. A strong dependence of the fluorescence quantum yield on the viscosity and polarity of the medium has been shown, i.e. the conjugation of the dye with polyethylene glycol does not lead to the loss of the properties
of the molecular rotor, while significantly reduces its aggregation. When incorporated into amyloid fibrils, the quantum yield of the dye increases by more than 40 times; the new dye can be regarded as an efficient fluorescent probe for amyloid fibrils detection and research. In this case, not only the intensity, but also the position of the absorption spectrum can be used as a sensitive parameter. The presence of blood plasma proteins (albumins) in the solution has practically no effect on the position of the absorption spectrum and has little effect on the fluorescence intensity of the probe.

Published: December 2021

We present a combined experimental and theoretical study of the effect of magnetic field on the luminescence from an ensemble of NV centers in diamond. It was found that the intensity of infrared luminescence associated with transitions between singlet levels of NV centers shows a pronounced increase of a near-zero magnetic field. The influence of the power and polarization of laser radiation on the amplitude and shape of the revealed local maximum in IR-luminescence of NV centers is investigated. An eight-level photophysical model of an NV center in the presence of an arbitrarily directed magnetic field has been constructed
and on its basis the calculation has been performed of the luminescence intensity emitted by an ensemble of NV center, both in the visible and infrared regions of the spectrum. It is shown that the phenomenological allowance for the cross-relaxation of NV centers between each other and with other paramagnetic
centers in a diamond within the framework of this model allows describing the experimentally observed fluorescence features of an ensemble of NV centers in the presence of weak magnetic fields.

COMPARATIVE STUDY OF SPECTRAL CHARACTERISTICS OF COMPLEXES OF HOECHST 33258 AND METHYLENE BLUE WITH BOVINE SERUM ALBUMIN
Authors: Antonyan A. P. , Petrosyan N. H. , Vardevanyan P. O. 
Published: December 2021

The comparative study on interaction of bisbenzimidazole compound Hoechst 33258 and thiazine dye methylene blue (MB) with bovine serum albumin (BSA) was carried out by spectroscopic methods. Denaturation curves as well as absorption spectra and differential absorption spectra of protein-ligand complexes
were obtained. Denaturation temperature of albumin complexes of BSA with Hoechst 33258 was shown to decrease with the growth of concentration ratio of ligand/protein, while for MB, vice versa, denaturation temperature increases. Changes in absorption spectra and differential absorption spectra of the complexes
of ligands with albumin were revealed, which result from the binding of these DNA-specific ligands to protein. It is supposed that at the interaction of Hoechst 33258 with BSA some loosening of protein compact structure occurs due to the partial loss of helicity of α-structures, while for MB an increase of the protein compact structure takes place.

Authors: Rotshteyn V. M. , Ashurov Kh. B. , Ashurov R. Kh. 
Published: December 2021

A technique for the express analysis of the products of technological processes is described, which was developed using the Raman spectroscopy method. The analysis of the Raman spectra includes the interpretation of the spectral bands, taking into account the values of the characteristic frequencies of the vibrational spectra of organic compounds, as well as the determination of the integral intensities of the corresponding spectral ranges. By example of the real time control procedure for the technological process of monosilane synthesis, the express analysis of tetraethoxysilane, which is a by-product of this technological process, is carried out. Significant advantages of using the express analysis method are demonstrated, which provide control over the normal course of the technological process and obtaining results that allow making adjustments
to the process flow diagram in order to optimize it.
