Drug-influenced gingival enlargement (DIGE) is a well-known adverse drug reaction associated with multiple medications. Although a benign condition, DIGE can have a significant impact on patients' aesthetic comfort and function. A surgical resection approach is usually proposed to treat severe and generalized DIGE.

Objectives: We investigated the relationship between the expression patterns and polymorphisms of the ACE2 and TMPRSS2 receptor genes associated with coronavirus disease 2019 (COVID-19) and the clinical course of SARS-CoV-2 infections.
Material And Methods: We examined 147 COVID-19 patients (41 asymptomatic, 53 symptomatic and 53 cases treated in the intensive care unit (ICU)) and 33 healthy controls.
With global demand for 3D printed medical devices on the rise, the search for safer, inexpensive, and sustainable methods is timely. Herein, we assessed the practicality of the material extrusion process for acrylic denture bases of which successful outcomes can be extended to implant surgical guides, orthodontic splints, impression trays, record bases and obturators for cleft palates or other maxillary defects. Representative materials comprising denture prototypes and test samples were designed and built with in-house polymethylmethacrylate filaments using varying print directions (PDs), layer heights (LHs) and reinforcements (RFs) with short glass fiber.

In our study, we aimed to investigate the prevalence of rs12979860, rs8099917 and rs12980275 SNPs in IL28B in patients with hepatitis B (HBV) or hepatitis C Virus (HCV) infection and to determine the relationship of these polymorphisms with plasma IL28B levels. For this purpose, 64 HBV-infected and 66 HCV-infected patients and 70 healthy individuals were included in the study.
View Article and Find Full Text PDFNovel mutations have been emerging in the genome of severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2); consequently, the evolving of more virulent and treatment resistance strains have the potential to increase transmissibility and mortality rates. The characterization of full-length SARS-CoV-2 genomes is critical for understanding the origin and transmission pathways of the virus, as well as identifying mutations that affect the transmissibility and pathogenicity of the virus. We present an analysis of the mutation pattern and clade distribution of full-length SARS-CoV-2 genome sequences obtained from specimens tested at Gazi University Medical Virology Laboratory.

Exercise training, which is incorporated both goal-based training such as task-oriented training (TOT) and aerobic training (AT), has been suggested to induce neuroprotection. However, molecular mechanisms which may underlie exercise-induced neuroprotection are still largely unknown.

The syntheses of 4-[4-(4,4,5,5-tetramethyl-2-imidazoline-3-oxide-1-oxyl-2-yl)phenoxy]phthalonitrile (3, CHNO) and 4-[4-(4,4,5,5-tetramethyl-2-imidazoline-1-oxyl-2-yl)phenoxy]phthalonitrile (4) were carried out by microwave-assisted nucleophilic aromatic substitution of 4-nitrophthalonitrile (2) by the pre-formed 2-(4-hydroxyphenyl)-4,4,5,5-tetramethyl-2-imidazoline-3-oxide-1-oxyl (1). Compounds 3 and 4 were characterized unambiguously by a rich array of analyses, such as melting point, FT-IR, MALDI-TOF MS, elemental analysis, UV-Vis, CV, EPR, magnetic measurements and single-crystal X-ray diffraction. Structural studies demonstrate that the C-H.

We retrospectively investigated the presence of EBV-DNA by real-time PCR in clinical samples of patients diagnosed as having hematologic malignancies while investigating the cause of lymphoproliferative disorders, and investigated its relationship to clinical manifestations.
Patients And Methods: Fifty clinical samples sent to Gazi University's hematology clinics between November 2013 and March 2018 were included.
Objectives: Several studies described single nucleotide polymorphisms (SNPs) on pattern recognition receptor (PRR) such as toll-like receptors (TLRs), dendritic cell-associated C-type lectin-1 (Dectin-1/CLEC7A) genes of patients with invasive fungal infections (IFIs) caused by Candida and Aspergillus. We screened TLR4, Dectin-1 and PTX3 polymorphisms in a Turkish population with invasive aspergillosis (IA) underlying haematological malignancies.
Methods: In this case-control study, a cohort of 59 patients with haematological malignancies were included.
Goal-based training such as task practice combined with aerobic training (AT) has been suggested to improve motor performance and neuroplasticity for people with Parkinson's Disease (PwPD); however, its effect on clinical outcomes is unclear. Therefore, the main aim was to investigate the effects of task-oriented circuit training combined with AT (TOCT-AT) on balance and gait in PwPD. The secondary aim was to investigate the effects of TOCT-AT on functional mobility, balance confidence, disease severity, and quality of life.

Characterization of the double bond conversion of acrylic resins is considered critical in the evaluation of dental materials due to the propensity of end-use devices to accumulate residual monomer and degradation products that can cause local and systemic side effects in high doses. In this study, the authors examine two different acrylic-based photopolymers indicated for 3D printing of dental prostheses using Fourier transform infrared spectroscopy: a denture base material comprising ≥75% ethoxylated bisphenol A dimethacrylate, and a crown-and-bridge material composed of >60% proprietary methacrylic oligomer and 15%-25% 2-hydroxyethyl methacrylate. Infrared spectroscopy data showed a conversion rate (240 s) of 52.

The aim of this study was to determine the prevalence of mixed infections with different HCV genotypes in Turkey and also to evaluate the current HCV genotype and sub-type distributions by a multicentered assessment.

In order to investigate the substitution position effect on the spectroscopic, electrochemical, and magnetic properties of copper phthalocyanines, a detailed structure-property analysis has been performed by examining two copper phthalocyanines that are octasubstituted by hexylsulfanyl chains respectively in the peripheral (Cu-P) and non-peripheral (Cu-NP) positions. Cu-NP showed a marked near-IR maximum absorption compared to Cu-P and, accordingly, a smaller HOMO-LUMO energy gap, calculated via the electrochemical results and simulations in the gas phase, as well as for Cu-NP from its crystallographic data. An electron-spin resonance (ESR) technique is used to extract the g values from the powder spectra that are taken at room temperature.

The simultaneous controlled introduction of preformed nitronyl nitroxide radicals on a cyclotriphosphazene core leads to a novel polyphosphazene monomer which is suitable for both n- and a p-type redox-active material in organic rechargeable batteries as demonstrated by electrochemistry. Additionally, absorption spectra and square-wave voltammetry were utilized to quantify the number of nitronyl nitroxide radical units on the cyclotriphosphazene scaffold.
