Here, we map the cancer research activity from the 29 countries across these regions over a 10-year period (2007-2016), using a standard scientometric approach. Research activity was compared with the countries' wealth and with the disease burden from different cancers, and analyses were also performed by the research domain (e.

Guidance toward the implementation of multicriteria decision analysis framework in developing countries.

Multiple Criteria Decision Analysis (MCDA) is increasingly used in health care mainly because it moves decision-making from ad hoc to an evidence-based and comprehensive process. Developing countries with more restricted financial and human research capacities, however, should consider their own methods of MCDA development and implementation. Areas covered: An MCDA framework to improve procurement decisions of off-patent pharmaceuticals was developed for developing countries and adapted to Indonesia, Kazakhstan and Vietnam during three policy workshops.

Metagenomic analysis of gut microbial communities from a Central Asian population.

Objective: Changes in the gut microbiota are increasingly recognised to be involved in many diseases. This ecosystem is known to be shaped by many factors, including climate, geography, host nutrition, lifestyle and medication. Thus, knowledge of varying populations with different habits is important for a better understanding of the microbiome.

Activated carbon-plasticised agarose composite films for the adsorption of thiol as a model of wound malodour.

Conditions such as diabetes, cardiovascular disease and long-term immobilisation can precipitate the development of chronic dermal ulcers. Such wounds are associated with inflammation and bacterial contamination which in turn can lead to the liberation of offensive odours that cause patient embarrassment and, in some instances, social isolation. Activated carbon-containing dressings have been used to manage the odours from such wounds.

Prevalence, awareness, treatment and control of dyslipidemia in older persons in urban and rural population in the Astana region, Kazakhstan.

Background: Despite high cardiovascular mortality in Central Asian republics of the former Soviet Union, there is limited information about major risk factors, including blood lipids. We investigated the prevalence of impaired concentrations of blood lipids, the awareness, treatment and control of hypercholesterolemia, and factors associated with these indicators in urban and rural populations in Kazakhstan.

Methods: We conducted a cross-sectional study of random urban and rural population samples (the state capital Astana and Akmol village).

Role of the immune system in cardiac tissue damage and repair following myocardial infarction.

Introduction: The immune system plays a crucial role in the initiation, development, and resolution of inflammation following myocardial infarction (MI). The lack of oxygen and nutrients causes the death of cardiomyocytes and leads to the exposure of danger-associated molecular patterns that are recognized by the immune system to initiate inflammation.

Results: At the initial stage of post-MI inflammation, the immune system further damages cardiac tissue to clear cell debris.

Preconditioning of Human Mesenchymal Stem Cells to Enhance Their Regulation of the Immune Response.

Mesenchymal stem cells (MSCs) have attracted the attention of researchers and clinicians for their ability to differentiate into a number of cell types, participate in tissue regeneration, and repair the damaged tissues by producing various growth factors and cytokines, as well as their unique immunoprivilege in alloreactive hosts. The immunomodulatory functions of exogenous MSCs have been widely investigated in immune-mediated inflammatory diseases and transplantation research. However, a harsh environment at the site of tissue injury/inflammation with insufficient oxygen supply, abundance of reactive oxygen species, and presence of other harmful molecules that damage the adoptively transferred cells collectively lead to low survival and engraftment of the transferred cells.

A Comprehensive Review of Topical Odor-Controlling Treatment Options for Chronic Wounds.

The process of wound healing is often accompanied by bacterial infection or critical colonization, resulting in protracted inflammation, delayed reepithelization, and production of pungent odors. The malodor produced by these wounds may lower health-related quality of life and produce psychological discomfort and social isolation. Current management focuses on reducing bacterial activity within the wound site and absorbing malodorous gases.

Aims: The evidence on the prevalence and distribution of diabetes and its determinants in Central Asia is sparse. The aim of the present study was to investigate the prevalence, awareness, treatment, and control of diabetes and factors associated with these characteristics in the population of Astana (capital) city and adjacent rural area in Kazakhstan.

Methods: Participants aged 50-75 years old, residing in Astana city (the capital) and Akmol village were invited to participate in a cross-sectional study.

Suppression of the senescence-associated secretory phenotype (SASP) in human fibroblasts using small molecule inhibitors of p38 MAP kinase and MK2.

Senescent cells show an altered secretome profile termed the senescence-associated secretory phenotype (SASP). There is an increasing body of evidence that suggests that the accumulation of SASP-positive senescent cells in humans is partially causal in the observed shift to a low-level pro-inflammatory state in aged individuals. This in turn suggests the SASP as a possible therapeutic target to ameliorate inflammatory conditions in the elderly, and thus a better understanding of the signalling pathways underlying the SASP are required.

Pharmacokinetic Properties of Cytokines in Their Targeted Delivery Based on Autologous Erythrocyte Pharmacocytes.

Introduction: Using autologous erythrocytes as drug carriers for targeted delivery of cytokines to the sites of inflammation could potentially provide new opportunities for treatment of patients with purulent diseases. The targeted characteristic of erythrocytes is associated with the nature of purulent inflammation, where a large amount of erythrocytes is phagocytized and drugs encapsulated into the erythrocytes could be easily released. On the other hand, autologous erythrocytes meet all the criteria for the ideal drug carrier.
