A PROBABILISTIC ASSESSMENT OF SARS-COV-2 HOST INTERACTIONS IN THE CONTEXT OF META-COMMUNITY AND URBAN ECOLOGY

Nehri, Leman Nur
Coronavirus disease 2019 (COVID-19) is an ongoing pandemic that was detected in Wuhan, China, in December 2019 and spread all around the world. COVID-19 is caused by Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which spreads through close contact. Many studies have been conducted on the transmission, virulence, and immune response of SARS-CoV-2. The intracellular mechanism of action of the virus and various host interaction pathways are also known. In addition, there are many studies on the mutant types of the virus. However, no study has been found on the microbial host interactions of the specific mutants of the Spike protein, which is one of the most important structural proteins of the virus. This protein allows the virus to enter the cell and is the main target of the ongoing vaccine studies. In this study, interactions between Spike protein variants and bacteria of gut microbiota were analyzed with a probabilistic programming language (PPL), WebPPL. It is preferred since it is an expressive and generative language that can infer from small data sets. The relationship between the three Spike protein mutants and the two SARS-CoV-2 variants with the intestinal microbiota was also investigated. As a result, it was found that different variants of Spike protein exist in the hosts that have dissimilar intestinal microbial compositions. Because of the fact that the microbe interplays are very dynamic systems, laboratory applications turn to be quite costly, time-consuming, and difficult in microbial interaction studies. This study is expected to be helpful for the applications of interactions between virus variants and microbiomes for laboratory environments.

Snoubar, Yaser; Tanrısever, Oktay Fırat (2019-10-01)
The purpose of this article is to compare the humanitarian relief operations in Van- Turkey earthquake and Tohoku- Japan earthquake 2011. Essentially, this study questions whether the long experiences of Turkey and Japan in the management of natural disasters, especially earthquakes, have affected the development of humanitarian relief operations, what are the humanitarian relief operations of the two countries to overcome the disaster and manage it and what measures should be taken in this regard to prepar...
An analysis of the prevalence of malaria in Turkey over the last 85 years
Piyal, Birgul; Akdur, Recep; Ocaktan, Esin; Yozgatlıgil, Ceylan (Informa UK Limited, 2013-01-01)
Background: Affecting 106 countries, malaria is a major global burden. Though intensive antimalaria efforts in Turkey have been successful in bringing down the number of cases, historically malaria was a serious public health concern.
An analysis of the incidence of measles in Turkey since 1960
Caliskan, Deniz; Piyal, Birgul; Akdur, Recep; Ocaktan, Mine Esin; Yozgatlıgil, Ceylan (2016-01-01)
Background/aim: The aims of this study were to evaluate measles incidence and the effect of elimination strategy interventions on the disease from 1960 to 2014 in Turkey. The administration of measles vaccine started in the rural regions in 1970; it was carried out as a campaign along with the National Vaccine Campaign in 1985, and it has been employed as combined measles, mumps, and rubella under the scope of the Measles Elimination Program (MEP) since 2006 in Turkey. While a dramatic decrease in the repor...
