[The methodological approaches to evaluation of effect of tuberculosis as socially significant infection on decreasing of public health quality].

The study reveals main methodological approaches in monitoring and evaluating role of socially significant infectious diseases in reducing quality of public health in the Russian Federation. The article proposes at population level the grouping of main risk factors affecting quality of public health, exemplified by epidemiology of tuberculosis. The purpose of the study is to develop methodology of exploration of impact of socially significant infections on decreasing of quality of public health exemplified by epidemiology of tuberculosis as infectious disease that is well studied in medical social aspects and having fully functioning TB control and high level monitoring system.

A Survival Analysis of Patients with Recurrent Epithelial Ovarian Cancer Based on Relapse Type: A Multi-Institutional Retrospective Study in Armenia.

Background: Annually, approximately 200 new ovarian cancer cases are diagnosed in Armenia, which is considered an upper-middle-income country. This study aimed to summarize the survival outcomes of patients with relapsed ovarian cancer in Armenia based on the type of recurrence, risk factors, and choice of systemic treatment.

Methods: This retrospective case-control study included 228 patients with relapsed ovarian cancer from three different institutions.

Toll like receptors TLR1/2, TLR6 and MUC5B as binding interaction partners with cytostatic proline rich polypeptide 1 in human chondrosarcoma.

Metastatic chondrosarcoma is a bone malignancy not responsive to conventional therapies; new approaches and therapies are urgently needed. We have previously reported that mTORC1 inhibitor, antitumorigenic cytostatic proline rich polypeptide 1 (PRP-1), galarmin caused a significant upregulation of tumor suppressors including TET1/2 and SOCS3 (known to be involved in inflammatory processes), downregulation of oncoproteins and embryonic stem cell marker miR-302C and its targets Nanog, c-Myc and Bmi-1 in human chondrosarcoma. To understand better the mechanism of PRP-1 action it was very important to identify the receptor it binds to.

HIV Blocks Interferon Induction in Human Dendritic Cells and Macrophages by Dysregulation of TBK1.

Unlabelled: Dendritic cells (DCs) and macrophages are present in the tissues of the anogenital tract, where HIV-1 transmission occurs in almost all cases. These cells are both target cells for HIV-1 and represent the first opportunity for the virus to interfere with innate recognition. Previously we have shown that both cell types fail to produce type I interferons (IFNs) in response to HIV-1 but that, unlike T cells, the virus does not block IFN induction by targeting IFN regulatory factor 3 (IRF3) for cellular degradation.

Vitamin B-complex initiates growth and development of human embryonic brain cells in vitro.

We studied a combined effect of subcomponents of vitamin B complex on the growth, development, and death of human embryonic brain-derived cells (E90) cultured using a modified method of Matson. Cell death was detected by trypan blue staining. According to our results, vitamin B-complex in low-doses promote the development, maturation, and enlargement of human embryonic brain cells, on the one hand, and increases the percent of cell death, which attests to accelerated maturation and metabolism, on the other.
