Breast cancer ranks among the most prevalent cancers. Enhancing the effectiveness of chemotherapy and patient survival is the objective of many studies. In the literature, no study has investigated the combined effect of vitamin c and curcumin with chemotherapy drugs on cell viability in the MCF-7 cell line, nor the mechanism of inflammation induced by cancer drugs, both in vitro and in silico.

Objectives: Mechano-sensitive odontoblast cells, which sense mechanical loading and various stresses in the tooth structure, synthesize early signaling molecules such as prostaglandin E2 (PGE2) and nitric oxide (NO) as an adaptive response. It is thought that these synthesized molecules can be used for the diagnosis and treatment of periodontal and periapical diseases. The aim of this study was to investigate the relationship between the severity of apical periodontitis (AP) and chronic periodontitis (CP) and serum (s) TNF-α, IL-10, PGE2 and NO levels, as well as PGE2 and NO levels in gingival crevicular fluid (GCF) samples.

This study aims to determine the phenological characteristics of thermal responses in the larvae of a Culex pipiens complex field population at the individual level under the influence of thermal regime of its habitat. The analysis is based on a structured population model quantifying the thermal responses of development time and survival under variable conditions and characterising the variety between the larvae (interindividual variety). During the study performed in Turkish Thrace on a monthly basis between May 2021 and June 2022, a total of 3744 larvae were reared as peer larval cohorts and 2330 larvae as siblings in artificial containers to be fully exposed to the natural thermal condition that was recorded hourly.

Bacterial products, host immune cells and cytokines have been reported to play an important role in the pathogenesis of apical periodontitis (AP). This study aimed to determine the main bacterial species in the microbiota as gram positive and negative and to compare the relationship between matrix metalloproteinase (MMP)-9 and tumor necrosis factor (TNF)-α with controlled patient groups. 60 patients with AP and extraction indication were included in the study.

The purpose of this study is to investigate the effects of different root canal irrigation protocols applied to the dentin and artificial aging procedures on the micro pushout bond strength (mPBS) between dentin and hybrid ceramic posts. Seventy-five single-rooted mandibular premolar teeth were divided into 5 groups (Gr1-5). 50 of the teeth were used for the mPBS tests (n = 10), whereas 25 were used for the smear layer examinations (n = 5).

To investigate the relationship between apical periodontitis [AP] severity and inflammatory markers [interleukin (IL)-12, tumor necrosis factor-alpha (TNF-α), and Mid-Regional Pro Adrenomedullin (MR-proADM)] in patients with AP. A total of 162 subjects were divided into three categories: AP group (n = 80), periodontitis (P) group (n = 42), healthy control group (n = 40). The scoring of disease severity in 80 AP patients without any periodontal disease, using dental radiographs, was based on "The Abscess Score" (AS), as those having at least 1 tooth with AP and severity of PAI 3-4 were classified as AS 1 (mild); those with only1 tooth and severity of PAI 5 as AS 2 (moderate) and those having > 2 tooth with severity of PAI 5 as AS 3 (severe).

Several animal species, including ants, have been reported to be capable of predation on ticks. However, determining factors in most interactions between ticks and predators have not yet been fully deciphered. We hypothesized that the ant species Lasius alienus, which is unknown whether it has any impact on ticks, may exhibit predation on the eggs of tick species Hyalomma marginatum, H.

In addition to alloantibodies, alloreactive memory B cell (mBC) evaluation has a potential for immunological risk assessment during transplantation processes. For the alloreactive mBCs evaluation currently, direct Flow Cytometric (FC) analysis using the HLA tetramer staining is an option. Evaluation of alloantibodies produced by the polyclonally stimulated alloreactive mBCs in in vitro culture system seems to be another useful approach, but this needs further downstream applications.

Aim: To evaluate the effects of favipiravir (FVP) on cell viability and cytotoxicity in human degenerated primary intervertebral disc (IVD) tissue cell cultures. Furthermore, the protein expressions of hypoxia-inducible factor 1 alpha (HIF-1α), nuclear factor-kappa-b (NF-kB), and interleukin-1 beta (IL-1β) were also examined.

Material And Methods: Untreated cell cultures served as the control group, named group 1.

Aim: To investigate the supplementation of alpha-lipoic acid (ALA) at the molecular level to determine its effect on primary cell cultures prepared from human intervertebral disc (IVD) tissue in an in vitro environment.

Material And Methods: Human primary cell cultures were prepared from IVD tissue resected during surgery. While cell cultures without ALA supplementation formed the control group, those with ALA supplementation formed the study group.

Objective: COVID-19 causes severe complications particularly in respiratory system especially in the elderly and those with poor general health. General and oral health are closely related to the course of such viral diseases. This study aims to reveal the relationship between the Dental Damage Stage (DD Stg) and the severity of COVID-19 disease.

Article Synopsis
  • The study investigates the effectiveness of using IL-6 and PAPP-A alongside imaging methods to assess the severity of apical periodontitis (AP) in 121 patients.
  • The patients were classified into three grades of AP severity based on dental radiographs, with a control group of 45 healthy volunteers (grade 0) also analyzed.
  • Findings showed that higher levels of IL-6 and PAPP-A in patients with severe AP (grade 3) correlated with disease severity and indicated a greater risk of developing AP, emphasizing the potential role of these biomarkers in evaluation and diagnosis.

Seventeen endemic and three sub-endemic species belonging to three subfamilies of Tettigoniidae (Orthoptera: Bradyporinae, Phaneropterinae and Tettigoniinae) were sampled during field trips throughout different regions of Anatolia between 2015 and 2018 (except one taxon). Acoustic parameters of these 20 bush-cricket species affiliated to 12 genera (Apholidoptera, Bradyporus, Decticus, Eupholidoptera, Parapholidoptera, Pezodrymadusa, Pholidoptera, Polysarcus, Psorodonotus, Squamiana, Uvarovistia and Yalvaciana) have been described for the first time in this study. Bioacoustical analysis shows that male calling songs are species-specific for the genera Bradyporus, Parapholidoptera, Pholidoptera, Apholidoptera, Uvarovistia and Psorodonotus.
