Proactive anti-inflammatory therapy with colchicine in the treatment of advanced stages of new coronavirus infection. The first results of the COLORIT study.

Actuality The course of the novel coronavirus disease (COVID-19) is unpredictable. It manifests in some cases as increasing inflammation to even the onset of a cytokine storm and irreversible progression of acute respiratory syndrome, which is associated with the risk of death in patients. Thus, proactive anti-inflammatory therapy remains an open serious question in patients with COVID-19 and pneumonia, who still have signs of inflammation on days 7-9 of the disease: elevated C-reactive protein (CRP)>60 mg/dL and at least two of the four clinical signs: fever >37.

[Combination therapy at an early stage of the novel coronavirus infection (COVID-19). Case series and design of the clinical trial "BromhexIne and Spironolactone for CoronаvirUs Infection requiring hospiTalization (BISCUIT)"].

The article focuses on effective treatment of the novel coronavirus infection (COVID-19) at early stages and substantiates the requirement for antiviral therapy and for decreasing the viral load to prevent the infection progression. The absence of a specific antiviral therapy for the SARS-CoV-2 virus is stated. The authors analyzed results of early randomized studies using lopinavir/ritonavir, remdesivir, and favipiravir in COVID-19 and their potential for the treatment of novel coronavirus infection.

[Proactive anti-inflammatory and anticoagulant therapy in the treatment of advanced stages of novel coronavirus infection (COVID-19). Case Series and Study Design: COLchicine versus ruxolitinib and secukinumab in open prospective randomIzed trial (COLORIT)].

The article is devoted to the treatment of the new coronavirus infection (COVID-19) in the advanced stages of the disease. The types of response of the immune system to the viral load of SARS-CoV-2 with the start of the inflammation process are considered. The situation is analyzed in detail in which the growing autoimmune inflammation (up to the development of a "cytokine storm") affects not only the pulmonary parenchyma, but also the endothelium of the small vessels of the lungs.

AVIFAVIR for Treatment of Patients With Moderate Coronavirus Disease 2019 (COVID-19): Interim Results of a Phase II/III Multicenter Randomized Clinical Trial.

In May 2020 the Russian Ministry of Health granted fast-track marketing authorization to RNA polymerase inhibitor AVIFAVIR (favipiravir) for the treatment of COVID-19 patients.

Steroid pulse -therapy in patients With coronAvirus Pneumonia (COVID-19), sYstemic inFlammation And Risk of vEnous thRombosis and thromboembolism (WAYFARER Study).

Introduction Coronavirus pneumonia not only severely affects the lung tissue but is also associated with systemic autoimmune inflammation, rapid overactivation of cytokines and chemokines known as "cytokine storm", and a high risk of thrombosis and thromboembolism. Since there is no specific therapy for this new coronavirus infection (COVID-19), searching for an effective and safe anti-inflammatory therapy is critical.Materials and methods This study evaluated efficacy and safety of pulse therapy with high doses of glucocorticosteroids (GCS), methylprednisolone 1,000 mg for 3 days plus dexamethasone 8 mg for another 3-5 days, in 17 patients with severe coronavirus pneumonia as a part of retrospective comparative analysis (17 patients in control group).

Chemometric deconvolution of gas chromatographic unresolved conjugated linoleic acid isomers triplet in milk samples.

A generally known problem of GC separation of trans-7;cis-9; cis-9,trans-11; and trans-8,cis-10 CLA (conjugated linoleic acid) isomers was studied by GC-MS on 100m capillary column coated with cyanopropyl silicone phase at isothermal column temperatures in a range of 140-170 degrees C. The resolution of these CLA isomers obtained at given conditions was not high enough for direct quantitative analysis, but it was, however, sufficient for the determination of their peak areas by commercial deconvolution software. Resolution factors of overlapped CLA isomers determined by the separation of a model CLA mixture prepared by mixing of a commercial CLA mixture and CLA isomer fraction obtained by the HPLC semi-preparative separation of milk fatty acids methyl esters were used to validate the deconvolution procedure.

[Hepatobiliscintigraphy in the diagnosis of obstructive jaundice].

The authors show the role of hepatobiliscintigraphy (HBSG) in cholelithiasis as a screening technique in evaluating the patency of the common bile duct, which allows cholecystectomy to be performed if there are normal values, without resorting to additional studies. They have reprospectively analyzed the results of clinical and instrumental studies in 101 patients with cholelithiasis and obstructive jaundice of various etiology in whom the diagnosis was verified by endoscopic cholangiopancreatography (ERCPG). The sensitivity, specificity, and diagnostic efficiency of the scintigraphic technique were 96.

[Our experience with the sentinel lymph node detection].

Background: Axillary lymph node staging is the most powerful predictor of survival in breast cancer women. Sentinel lymph node biopsy (SLNB) is more accurate method in evaluation of axillary lymph node staging than complete axillary lymph node dissection (CALND) because of more precious histological and imunohistochemical assessment of the first draining lymph nodes. Furthermore, SLNB eliminates complications resulting from CALND.

[Characteristics of borderline modulation frequencies in the differentiation of tonal and amplitude-modulated stimuli following the removal of the inferior colliculus in rats].

Elaboration of differentiation between sound stimuli was carried out in 15 laboratory rats. After bilateral ablations of auditory inferior colliculi the border frequency of stimulus amplitude modulation was determined for all rats when they still could differentiate between tonal and amplitude-modulated stimuli. Decrease in frequency of modulation by 2 Hz and more from the border frequency caused a complete loss of ability to differentiate.

Improvement of the basidiomycete Coprinus sp.

Coprinus sp. C-1 (obtained from uranium mines) was subjected to improvement procedures with the aim of preparing a strain that could degrade cellulose in the straw substrate more rapidly and effectively. The original C-1 strain was highly resistant to UV and X radiation but it was rather sensitive to tris(2-chloroethyl)amine, the effect of which increased when applying simultaneously compounds reacting with mercapto groups of some enzymes.
