Validity and Reliability of the Turkish Version of the Patient-Reported Impact of Spasticity Measure in Multiple Sclerosis.

Background: We aimed to evaluate the validity and reliability of the Turkish version of the Patient-Reported Impact of Spasticity Measure (PRISM-TR).

Methods: Expert opinions and the forward-back translation method were used for linguistic validation. Cronbach α and test-retest analysis were performed for reliability analysis.

A machine learning approach to determine the risk factors for fall in multiple sclerosis.

Background: Falls in multiple sclerosis can result in numerous problems, including injuries and functional loss. Therefore, determining the factors contributing to falls in people with Multiple Sclerosis (PwMS) is crucial. This study aims to investigate the contributing factors to falls in multiple sclerosis using a machine learning approach.

Differential synergistic effects of palbociclib and doxorubicin on doxorubicin-resistant cancer cells with diverse tumor origins.

Palbociclib is a dual inhibitor of cyclin-dependent kinases 4 and 6 (CDK4/6). Palbociclib has frequently been studied in breast cancer cells and has also been linked to function of P-glycoprotein (P-gp), main protein responsible for cancer drug resistance. However, the effect of Palbociclib on cancer drug resistance and specifically doxorubicin-resistant cells overexpressing P-gp have limitedly been studied in the literature.

Investigation of evolutionary dynamics for drug resistance in 3D spheroid model system using cellular barcoding technology.

Complex evolutionary dynamics governing the drug resistance is one of the major challenges in cancer treatment. Understanding these mechanisms requires a sequencing technology with higher resolution to delineate whether pre-existing or de novo drug mechanisms are behind the drug resistance. Combining this technology with clinically very relevant model system, namely 3D spheroids, better mimicking tumorigenesis and drug resistance have so far been lacking.

In-vitro determination of inhibitory effects of probiotic strains on Clostridioides difficile.

Commercial probiotic strains inhibited C. difficile, and other Clostridium cultures with zones 14.2-78.

The Regulation of GLT-1 Degradation Pathway by SIRT4.

Glial cells give rise to glioblastoma multiform as a primary brain tumor. In glioblastomas, neurons are destroyed via excitotoxicity which is the accumulation of excess glutamate in synaptic cavity. Glutamate Transporter 1 (GLT-1) is the main transporter that absorbs the excessive glutamate.

Perceptions of Justice By Algorithms.

Unlabelled: Artificial Intelligence and algorithms are increasingly able to replace human workers in cognitively sophisticated tasks, including ones related to justice. Many governments and international organizations are discussing policies related to the application of algorithmic judges in courts. In this paper, we investigate the public perceptions of algorithmic judges.

Early postnatal metabolic profile in neonates with critical CHDs.

Background: Cyanotic CHD is a life-threatening condition that presents with low oxygen saturation in the newborn period. Hypoxemia might cause alterations in the metabolic pathways. In the present study, we aimed to evaluate the early postnatal amino acid and carnitine/acylcarnitine profiles of newborn infants with cyanotic CHD.

The interaction of SIRT4 and Calreticulin during ER stress in glia cells.

Endoplasmic Reticulum (ER) stress is the response that occurs after the dysfunction of ER and its structure. Activated UPR triggers a stress response using ER membrane proteins such as PERK, IRE-1, GRP78, ATF5 ve ATF6. Sirtuins are enzymes that carry out post-translational modifications such as deacetylation and ADP-ribosylation.

The expression of glutamate metabolism modulators in the intracranial tumors and glioblastoma cell line.

Background: The accumulation of excess glutamate in the synapse leads to excitotoxicity, which is the underlying reason of neuronal death in intracranial tumors.

Methods And Results: We identified the expression levels of glutamate dehydrogenase, glutamine synthetase and sirtuin 4 in U87 cell line and various intracranial tumors. mRNA expressions of glutamate dehydrogenase (GDH), glutamine synthetase (GS) and sirtuin 4 (SIRT4) were analyzed in various intracranial tumors using qPCR.

Impact of chemerin, lipid profile, and insulin resistance on disease parameters in patients with multiple sclerosis.

Introduction: Plasma chemerin, which has chemotactic and adipogenic functions, is increased in several inflammatory diseases. However, its relationship with multiple sclerosis (MS) has not been explored yet. In this study, we aimed to determine chemerin levels and their possible role in MS.

Systems Biology and Experimental Model Systems of Cancer.

Over the past decade, we have witnessed an increasing number of large-scale studies that have provided multi-omics data by high-throughput sequencing approaches. This has particularly helped with identifying key (epi)genetic alterations in cancers. Importantly, aberrations that lead to the activation of signaling networks through the disruption of normal cellular homeostasis is seen both in cancer cells and also in the neighboring tumor microenvironment.

15-LOX-1 has diverse roles in the resensitization of resistant cancer cell lines to doxorubicin.

Lipoxygenases (LOXs) are a family of enzymes that can oxygenate polyunsaturated fatty acids. As a member of the family, 15-lipoxygenase-1 (15-LOX-1) specifically metabolizes arachidonic acid and linoleic acid. 15-LOX-1 can affect physiological and pathophysiological events via regulation of the protein-lipid interactome, alterations in intracellular redox state and production of lipid metabolites that are involved in the induction and resolution of inflammation.

Programmed cell death ligand-1 expression in gastroenteropancreatic neuroendocrine tumors.

Purpose: Gastroenteropancreatic tumors (GEPNETs) is a heterogeneous disease with variable clinical course. While promising therapeutic options exist for other adult cancers, there are no new molecular-based treatments developed for GEPNETs. One of the main targets of cancer immunotherapy is the Programmed Cell Death Ligand-1 (PD-L1) pathway.
