Age-realted dementia in Kazahstan: adaptation of the 10/66 dementia research group population -based study protocol
Background. The prevalence of dementia is increasing worldwide as the population ages and affects
10 % of the population over 65 years old and 40 % of people over the age of 80.[1] In Kazakhstan, as well
as in other countries around the world, the population of aged people has been increasing over the past
decades. According to available statistics, by the end of 2013, the percentage of people aged 65 and older
in Kazakhstan was 6.7% [2]. Given the fact that Kazakhstan's current population is about 17,221 million
people [2], and based on data from the global statistics, it can be assumed that at least 115,000 elderly
people could be suffering from age-related dementia. Nevertheless, such pathology is currently may not
being diagnosed in Kazakhstan; consequently giving no accurate statistical data on the number of people
suffering from this age-related pathology. Thus, the aim of this study is to estimate true prevalence of
dementia and assess the risk factors associated with the disease

Astroprotective potential of extract from limonium gmelinii for stroke therapy
It's known that proinflammatory cytokines, such asTNF-a, produced by injured
neurons and infiltrated leukocytes, involved in every aspect of stroke. Cytokines promote
activation of astroglia, induce oxidative stress thereby exacerbating brain tissue damage. There
is a number of data indicating that polyphenols can provide protection against neurodegenerative
changes. It has been reported previously, that reach with polyphenols extract of Limonium
gmelinii exerts a wide range of therapeutic actions. Here, we aimed to study antioxidant and
anti-inflammatory potential of L. gmelinii under exposure of TNF-a in vitro
Research of microstructure and microbiological indicators of pasta products from non-traditional raw materials
Modern trends in the development of pasta production are based on the use of starch-containing raw materials for the production of medicinal and preventive pasta products. In this connection, an important observation is the state of protein and starch in pasta flour, which can be achieved by electron microscopy of the microstructure of macaroni products. Therefore, the study of microstructures and microbiological indicators of pasta from non-traditional raw materials will be relevant. The practical value of the research is characterized by improved consumer properties of pasta made from non-traditional raw materials. The novelty of the research is the development of scientific and technological bases for the production of pasta from non-traditional polycereal raw materials. The results obtained: the analysis of the obtained electronic micro-drawings showed that the microstructure of pasta from non-traditional raw materials corresponds to the standards in comparison with the control sample. The following types of mycotoxins were found in pasta from non-traditional raw materials in permitted quantities: aflatoxin B1, aflatoxin M1, zearalenone, deoxynivalenol, ochratoxin A, fumonisin, patulin, T-2. For example, the amount of zearalenone (mg/kg): in pasta according to recipe No. 1 – 0.0637, according to recipe No. 2 – 0.0251 and according to recipe No. 3 – 0.0758; in flour raw materials – according to recipe No. 1 – 0.1485, according to recipe No. 2 – 0.0261 and according to recipe No. 3 – 0.2
Small molecule targeting of the p38/Mk2 stress signaling pathways to improve cancer treatment
Purpose: Although a long-term goal of cancer therapy always has been the development of agents that selectively destroy cancer cells, more recent trends have been to seek secondary agents that sensitize cancer cells to existing treatment regimens. In this regard, the present study explored the possibility of using small molecule inhibitors of p38MAPK/MK2 stress signaling pathways as potential agents to enhance the sensitivity of cancer cells with abrogated G1 checkpoint to the DNA damaging agent etoposide by specifically targeting the DNA damage-induced G2 cell cycle checkpoint. Methods: We have applied CCK8 and FACS-based viability assays and cell cycle analysis to investigate the effect of small molecules SB203580 and MK2.III on the sensitivity of small cell lung cancer cells (SCLC) that lack the G1 checkpoint to the DNA damaging agent Etoposide when used in combination. We have also assessed the effectiveness of combination chemotherapy on tumor xenograft suppression with etoposide and MK2.III in immunosuppressed mice. In addition, additional CCK8 cell viability analysis of the MDA-MB-231 breast cancer cell line, and SW620, and SW480 colorectal cancer cell lines was performed. Results: Results suggest that etoposide produces a profound effect on the cell cycle profile of cells in a manner that is consistent with the degree of cell viability that is seen using the viable cell assay. Results of the co-treatment experiments revealed that the p38/MK2 kinase inhibitors SB203580 and MK2.III both enhanced the DNA-damaging effects of etoposide on NCI-H69 cell viability in vitro. Results revealed that in vivo MK2.III was able to act as a chemosensitizer when used in combination with etoposide making NCI-H69 lung cancer cells sensitive to chemotherapeutic drug by 45% compared to single usage of the drug. We also report that MK2.III sensitizes metastatic cell lines SW-620 and MDA-MB-231 to etoposide but does not increase the sensitivity of non-metastasizing SW-480 colorectal cells to DNA damaging agent in vitro. Conclusion: Findings reported in this study provide evidence that specific inhibitors of MK2 may indeed improve overall cancer therapy; however, their effectiveness depends on cell types
