Minimally Invasive Sacroiliac Fusion; Current Insights And A Comprehensive Literature Review, Aydin Apaydin, Mehmet Yurtluk, Khoi̇ Than

Turkish Journal of Medical Sciences

The sacroiliac joint (SIJ) is an easily dismissable cause of lower back pain (LBP). Recently has gained attention as the source of pain and surgeries addressing this issue have gained attention among surgeons. Classically open fusion surgery was used for the pelvic and sacral fractures to stabilize the structure and then open SIJ fusion surgery started to be used for pain management until the discovery of minimally invasive surgery (MIS). MIS offered fast and effective pain relief with significantly less risk of adverse events following the surgery. Therefore gaining more and more attention each day among surgeons. Our literature review …

Oral Small Molecule Agents In Management Of Ulcerative Colitis: Fact Or Fancy, Benan Kasapoğlu, Ati̇lla Ertan Dec 2023

Oral Small Molecule Agents In Management Of Ulcerative Colitis: Fact Or Fancy, Benan Kasapoğlu, Ati̇lla Ertan

Turkish Journal of Medical Sciences

Ulcerative colitis is a chronic, immune-mediated disease characterized by recurring episodes of mucosal inflammation in the colon and rectum. The primary pathogenic mechanism of ulcerative colitis is the dysregulation of the mucosal immune response. The disease follows a relapsing-remitting course, and the goal of management is to successfully induce and then maintain remission. Effectively managing this chronic disease requires addressing all aspects of it. Currently, we have various antitumor necrosis factor agents and novel biologics available for treating ulcerative colitis patients with moderate-to-severe disease. However, none of the existing treatments are considered entirely satisfactory or ideal in these cases. After …


Long Noncoding Rnas In Pancreas Cancer: From Biomarkers To Therapeutic Targets, Esra Güzel Tanoğlu, Seyfure Adigüzel, Alpaslan Tanoğlu, Zehra Betül Aydin, Güli̇zar Hocaoğlu, Samet Ebi̇nç Dec 2023

Long Noncoding Rnas In Pancreas Cancer: From Biomarkers To Therapeutic Targets, Esra Güzel Tanoğlu, Seyfure Adigüzel, Alpaslan Tanoğlu, Zehra Betül Aydin, Güli̇zar Hocaoğlu, Samet Ebi̇nç

Turkish Journal of Medical Sciences

Long noncoding RNAs (lncRNAs) are noncoding RNA molecules with a heterogeneous structure consisting of 200 or more nucleotides. Because these noncoding RNAs are transcribed by RNA polymerase II, they have properties similar to messenger RNA (mRNA). Contrary to popular belief, the term "ncRNA" originated before the discovery of microRNAs. LncRNA genes are more numerous than protein-coding genes. They are the focus of current molecular research because of their pivotal roles in cancer-related processes such as cell proliferation, differentiation, and migration. The incidence of pancreatic cancer (PC) is increasing around the world and research on the molecular aspects of PC are …


Expression Of Pfkfb Isoenzymes During In Vitro Differentiation Of Mouse Embryonic Stem Cells Into Insulin-Producing Cells, Sai̇me Güzel, Abdullah Yalçin, Yunus Gürpinar, Sabi̇re Güler Dec 2023

Expression Of Pfkfb Isoenzymes During In Vitro Differentiation Of Mouse Embryonic Stem Cells Into Insulin-Producing Cells, Sai̇me Güzel, Abdullah Yalçin, Yunus Gürpinar, Sabi̇re Güler

Turkish Journal of Medical Sciences

Background/aim: Type 1 diabetes mellitus (T1DM) is caused by the autoimmune-mediated destruction of insulin-producing cells (IPCs) and still has no effective cure. Better understanding of the molecular mechanisms involved in the differentiation of embryonic stem cells (ESCs) into IPCs may help us improve the therapeutic strategies for treating T1DM. 6-phosphofructo-2-kinase/fructose-2,6- bisphosphatases (Pfkfb1-4) are key regulators of glucose metabolism. Although Pfkfb3 has been shown to be required for the growth of early differentiated mouse ESCs (mESCs), more studies are needed to further assess the roles of Pfkfb isoenzymes in embryonic development and differentiation, particularly into specific cell types. In this study, …

Evaluation Of The Cytotoxic Effect Of Titanium Dioxide Nanoparticles In Human Embryonic Lung Cells, Olkan Afşar, Çağatay Oltulu Dec 2023

Evaluation Of The Cytotoxic Effect Of Titanium Dioxide Nanoparticles In Human Embryonic Lung Cells, Olkan Afşar, Çağatay Oltulu

Turkish Journal of Medical Sciences

Background/aim: Titanium dioxide nanoparticles are widely used in a variety of products, including sunscreens, paints, and ceramics. However, their increasing use has raised concerns about their potential health risks. Titanium dioxide nanoparticles have been shown to have the ability to enter the bloodstream and accumulate in various tissues, reaching the fetus via the placenta. The aim of this study was to investigate the cytotoxic effects of titanium dioxide nanoparticles on a human embryonic lung cell line (HEL 299/An1) and the formation of oxidative DNA damage. Materials and methods: The cytotoxic effects of brookite-based titanium dioxide nanoparticles (<100 nm) were assessed using the 3-(4,5-dimethyldiazol-2-yl)-2,5 diphenyl tetrazolium bromide (MTT) assay for 24 and 48 h. Cell titanium levels were determined using inductively coupled plasma mass spectrometry. Oxidative DNA damage was assessed by measuring the levels of 8-hydroxy-2- deoxyguanosine (8-OHdG) as a biomarker. Results: Titanium dioxide nanoparticles caused dose-dependent cytotoxicity in HEL 299/An1 cells. The IC50 values were 25.93 μM and 0.054 μM after 24 h and 48 h of exposure, respectively. Cell titanium levels were found to be 25,967 ppb after 24 h and 210,353 ppb after 48 h (p < 0.01). 8-OHdG was detected at 32.96 ng/mL after 24 h of exposure and 17.89 ng/mL after 48 h of exposure. Conclusion: In our study, it was shown that titanium nanoparticles caused dose-dependent cytotoxicity and oxidative DNA damage in human embryonic lung cells. The nanoparticles also accumulated in cells and were taken up in higher amounts after 48 h of exposure. These findings suggest that titanium dioxide nanoparticles may pose a health risk, especially for pregnant women who may not be aware of their pregnancy. Therefore, it is important to take preventive measures to reduce exposure to these nanoparticles.

Different Roles Of Endothelial Cell-Derived Fibronectin And Plasma Fibronectin In Endothelial Dysfunction, Xiaoxin Luo, Weixiong Jian Dec 2023

Different Roles Of Endothelial Cell-Derived Fibronectin And Plasma Fibronectin In Endothelial Dysfunction, Xiaoxin Luo, Weixiong Jian

Turkish Journal of Medical Sciences

MDABackground/ aim: Atherosclerosis is significantly influenced by endothelial cell activation and dysfunction. Studies have demonstrated the substantial presence of fibronectin (Fn) within atherosclerotic plaques, promoting endothelial inflammation and activation. However, cellular Fn (cFn) secreted by various cell types, including endothelial cells and smooth muscle cells, and plasma Fn (pFn) produced by hepatocytes. They are distinct forms of Fn that differ in both structure and function. The specific contribution of different types of Fn in promoting endothelial cell activation and dysfunction remain uncertain. Therefore, this study aimed to investigate the respective roles of pFn and endothelial cell-derived Fn (FnEC) in promoting …
