Anticancer peptides (ACPs) are a class of molecules that have gained significant attention in the field of cancer research and therapy. ACPs are short chains of amino acids, the building blocks of proteins, and they possess the ability to selectively target and kill cancer cells. One of the key advantages of ACPs is their ability to selectively target cancer cells while sparing healthy cells to a greater extent.

This study presents a tetra-substituted phthalonitrile derivative, namely, diethyl 2-(3,4-dicyano-2,5-bis(hexyloxy)-6-(4-(trifluoromethoxy)phenoxy)phenyl)malonate (), cyclotetramerizing in the presence of some metal salts. The resultant hexadeca-substituted metal phthalocyanines [M= Co, Zn, InCl)] (-) were used for the modification of reduced graphene oxide for the first time. The effect of the phthalonitrile/metal phthalocyanines on biological features of reduced graphene oxide (rGO) was extensively examined by the investigation of antioxidant, antimicrobial, DNA cleavage, cell viability, and antibiofilm activities of nanobioagents (-).

The concentrations of heavy metals in soft sediments of the Manavgat and Lara regions in Antalya, Türkiye were investigated to assess contamination levels and their potential sources, followed by multivariate statistical analysis and generation of spatial distribution maps. Results showed low contamination levels for As, Zn, and Cu, moderate contamination for Pb, Ni, and Mn, and very high accumulation for Co and Cr. Geoaccumulation index (Igeo) and contamination factor (CF) analyses revealed moderate enrichment for Mn and low enrichment for As, indicating no human-induced contamination in Cu, Pb, Zn, Mn, and As, while Ni, Co, and Cr originated mainly from agriculture.

In this study, precipitation; temperature (maximum, minimum, and average temperature) values of Eskişehir, Konya, Afyonkarahisar, Uşak, and Kütahya for years (2007-2018); and protein content, macro sedimentation (MSDS), thousand kernel weight (KW), test weight (TW) relations, and the effect of climate values on quality were investigated. The Kriging method was used by ArcGIS software for creating quality maps of Eskişehir, Konya, Afyonkarahisar, Uşak, and Kütahya provinces in the light of obtained data from these examined quality criteria, yield, and climate factors. The quality of bread wheat, which includes protein content, macro sedimentation, thousand kernel weight, and test weight, is highly affected by the subject precipitation, maximum temperature, minimum temperature, average temperature, and precipitation.

Active food packaging has become attractive because of the possibility to provide a longer shelf-life by loading functional agents into the packages to maintain the quality of food products. Herein, photoluminescent and transparent polyvinyl alcohol (PVA)-based composites embedding multicolor fluorescent carbon dots (CD/PVA) were prepared by the solvent casting method. The prepared CDs emit a strong and stable fluorescence in solution while the CD/PVA composite films were transparent, flexible, and showed UV-blocking activity with a strong fluorescence emission.

In this study, it was aimed to determine the elemental composition of 47 propolis samples collected from different regions of Turkey by X-ray fluorescence spectroscopy. According to the results, the most abundant elements in propolis samples were the Ca, K, and Si with the mean values as 1556, 1383, and 731 mg/kg, respectively. Additionally, there were high degrees of positive and strong correlations of Al with S (0.

The infestation of human and animal tissues or organs by the larvae of flies is collectively termed as myiasis. The occurrence of oral myiasis is analogously low compared with cutaneous myiasis as oral tissues are not habitually exposed to the external environment. Oral myiasis predominantly affects the periodontium, buccal and/or palatal mucosa, lips, and tongue.

Article Synopsis
  • A series of bis- and tetrakis-1,2,3-triazole derivatives were successfully synthesized using copper-catalyzed azide-alkyne cycloaddition, achieving yields between 73-95%, and these compounds showed notable DNA cleavage activity, particularly tetrakis-1,2,3-triazole analog 6g, which completely degraded plasmid DNA.
  • Molecular docking studies indicated that 6g binds to DNA's minor groove through various noncovalent interactions.
  • Additionally, several derivatives demonstrated antibacterial and antifungal properties against specific strains, with compound 4d showing the best antibacterial effects against E. coli, while compound 5 had superior antifungal activity against C. albicans, highlighting

Purpose: The purpose of the study was to evaluate the stress distribution in various miniplates that were used in cases that underwent advancement with total mandibular subapical osteotomy (TMSO) using finite element analysis (FEA).

Material And Method: Cone beam computed tomography (CBCT) images of a patient with appropriate bone tissues were used as a reference for the modeling of the mandible. In all mandibular models, horizontal TMSO was performed in a region 5 mm away from the apex of the teeth and vertical TMSO was performed in the retromolar region, 10 mm posterior to the second molar tooth.

Introduction: Toxoplasma gondii is a protozoan parasite that has a widespread distribution among mammalians and birds. One of the reasons for the high prevalence may be due to ingesting oocyst disseminated by stray cats' feces. In Turkey, most of the citizens are closely associated with stray cats and they love to pet and feed them on the streets.

A series of novel 1,4-naphthoquinone-triazole hybrids, N-(3-amino-1,4-dioxo-1,4-dihydronaphthalen-2-yl)-2-(4-R-1H-1,2,3-triazol-1-yl)acetamide, was synthesized by click chemistry in the presence of sodium ascorbate and copper(II) sulfate pentahydrate in 81-94% yield. Various biological properties of the synthesized compounds including DNA binding/cleavage, antioxidant, antibacterial and antifungal properties were evaluated. The DNA binding study was performed using dsDNA and G-quadruplex DNA.

Article Synopsis
  • The study aimed to explore how the positions of molar roots relate to the occurrence of antral pseudocysts (APs) in patients.
  • Involving 160 patients, the research categorized molar root relationships relative to the maxillary sinus and analyzed how these correlate with AP presence and size, considering gender, side, and age differences.
  • Findings indicated that roots extending into the sinus floor significantly increased the likelihood and size of APs, suggesting that occlusal forces on the Schneiderian membrane could promote their formation.

A magnetic solid-phase extraction (MSPE) method was developed for simultaneous preconcentrations of U(VI) and Th(IV) before their measurements by inductively coupled plasma optical emission spectrometry (ICP-OES). The main idea of this biotechnological application depends on the use of bacteria, thermophilic Bacillus cereus SO-14, as a solid-phase biosorbent. It was immobilized to γ-FeO magnetic nanoparticles and used for MSPE.

The authors report a rare case of intraosseous hemangioma of the mandible in a 14-year-old male. Surgical intervention with embolization is as important as histological and radiological examination to reduce the bleeding complication. Magnetic resonance angiography is paramount of importance in these lesions to detect the supplier arteries.

Focal nodular hyperplasia (FNH) is the second most common benign tumor of the liver and constitutes 4% of all primary hepatic tumors in pediatric population. Imaging characteristics of FNH in adults are well known, but those in children have rarely been reported. Here we describe the natural course of a giant hepatic FNH, which was followed up from childhood to adulthood for 12 years using computed tomography (CT) imaging and liver enzyme tests (LET).
