The Nlrp3 Inflammasome: A New Player In Neurological Diseases, Eli̇f Eren, Nesri̇n Özören
Turkish Journal of Biology
Inflammasomes are supramolecular protein complexes implicated in the detection of pathogens or danger-associated molecules and are responsible for mounting the first line of innate immune response to counteract these signals and restore tissue homeostasis. Among different inflammasomes identified so far, NLRP3 is of main interest since mutations in Nlrp3 gene are associated with autoinflammatory diseases such as Muckle-Wells syndrome, neonatal onset multisystem inflammatory disease, and familial cold urticaria/autoinflammatory syndrome. On the other hand, whereas other inflammasomes are mainly detectors of specific molecular motifs, NLRP3 is acting as a general sensor of cellular perturbations including potassium efflux, lysosomal damage, and ROS …

Pore Length- And Ion Concentration-Dependent Ionic Current In Cylindrical Nanopores: An Atomistic Molecular Dynamics Study, Nazar İleri̇ Ercan
Pore Length- And Ion Concentration-Dependent Ionic Current In Cylindrical Nanopores: An Atomistic Molecular Dynamics Study, Nazar İleri̇ Ercan
Turkish Journal of Chemistry
The sensing of individual molecules as they pass through nanopores under an external field is a popular research field. The approach is simply based on the detectable temporary blockades in the ionic current as the molecules pass through the nanopores. These signatures of the current have been shown to be a function of nanoparticle and nanopore size and geometry as well as the external electric field. However, models developed in this context fail to predict the experimentally observed behavior in technologically important shorter nanopores. Here we present atomistic molecular dynamics simulation results from colloidal nanoparticle translocation through mid-to-low aspect ratio …

Novel Voltammetric Investigation Of Dipyridamole At A Disposable Pencil Graphite Electrode, Iulia Gabriela David, Lorelei Iordache, Dana Elena Popa, Mihaela Buleandra, Victor David, Emilia-Elena Iorgulescu
Turkish Journal of Chemistry
The present paper describes the voltammetric analysis of dipyridamole (DIP) at a cheap, disposable pencil graphite electrode (PGE). The working conditions were optimized with regard to the electrode material and the supporting electrolyte. Cyclic voltammetric investigations emphasized that DIP is irreversibly oxidized at the PGE. The electrode process is pH-dependent and controlled by both diffusion and adsorption. For DIP quantitative determination a differential pulse voltammetric (DPV) method in phosphate buffer solution pH 7.00 was developed. DIP's oxidation peak current varied linearly with the analyte concentration, presenting two linear ranges, namely 5.00 $\times $ 10$^{-7}$-2.50 $\times $ 10$^{-5}$ M and 2.50 …

Genetic Diversity, Phylogeography And Population Gene Flow Of Tunisian Pistacia Vera L., Sarra Choulak, Zined Marzouk, Khaled Chatti̇, Soumaya Rhouma-Chatti̇, Rim Ouni̇, Noureddine Chatti
Turkish Journal of Botany
The aim of this paper was to determine how the pistachio trees evolve, and the evolving factors that influence pistachio population establishment. For that, we investigated pistachio genetic structure from some regions of Tunisia, by sequencing two noncoding chloroplastic regions (trnL (UAA) and trnL-trnF intergenic spacer). We found strong genetic diversity among groups, with the absence of high differentiation between population pairs. A deep phylogeographical break separated two major clusters: "El-Guetar and "Gafsa/Sidi-Bouzid. This conclusion is proved by the haplotype networks, the phylogenetic trees, and the molecular variance analysis. Different interpretations were proposed to explain this cytoplasm dimorphism, based on …

Characterizing Microsatellite Polymorphisms Using Assembly-Based Andmapping-Based Tools, Gülfem Demi̇r, Can Alkan
Turkish Journal of Biology
Microsatellite polymorphism has always been a challenge for genome assembly and sequence alignment due to sequencing errors, short read lengths, and high incidence of polymerase slippage in microsatellite regions. Despite the information they carry being very valuable, microsatellite variations have not gained enough attention to be a routine step in genome sequence analysis pipelines. After the completion of the 1000 Genomes Project, which aimed to establish the most detailed genetic variation catalog for humans, the consortium released only two microsatellite prediction sets generated by two tools. Many other large research efforts have failed to shed light on microsatellite variations. We …
