Background: Terbinafine is an allylamine antifungal that is effective against many fungi, dermatophytes and moulds. Analytical methods are required for the determination of terbinafine in biological fluids to perform therapeutic drug monitoring and pharmacokinetic studies. Objective: The aim of this study was to develop and validate a novel and fast method combining dilute and shoot approach and high-performance l Read More

Introduction: The alkyl esters of p-hydroxybenzoic acid at the C-4 position, “the parabens,” including methyl, ethyl, propyl, and butyl, are widely used as antimicrobial preservatives in foods, cosmetics, and pharmaceuticals. Official regulations on the use of these compounds make their analysis essential for the estimation of their exposure. Methods: On this basis, the presented study was realized to develop a simple, sel Read More

Objective: The electrochemical analysis of ephedrine which is a sympathometric drug has been studied using poly(Nile blue A) modified glassy carbon electrodes, cyclic voltammetry, differential pulse voltammetry and square wave voltammetry. Methods: The modified electrodes were prepared by potential cycling electropolymerization of Nile blue A in 0.1 M phosphate buffer solution at pH 6.0. The redox behavior of ep Read More

Background: Electroanalytical methods are very functional to detect drugs in pharmaceuticals (tablets, syrups, suppositories, creams, and ointments) and biological samples. Objective: This study is aimed to make selective, sensitive, simple, fast, and low cost electrochemical analysis of expectorant drug guaifenesin in pharmaceuticals and serum samples. Methods: Differential pulse adsorptive stripping voltammetric met Read More

Introduction: In the present study, a sensitive and selective liquid chromatographytandem mass spectrometry (LC-MS/MS) method was described for the determination of ceftiofur (CEF) in cow milk and pharmaceutical preparations. CEF is an antibiotic compound, which is commonly used in the treatment of animal diseases such as respiratory system, soft tissue, and foot infections, as well as postpartum acute puerperal metritis.

Background: Bronchial asthma and chronic obstructive pulmonary disease (COPD) are among the most common chronic diseases. Roflumilast is a novel, potent, selective, and long-acting phosphodiesterase 4 (PDE-4) inhibitor for the treatment of bronchial asthma and COPD. It has anti-inflammatory effects, and it has been shown to reduce exacerbations and improve pulmonary function in patients with COPD. Although t Read More

Background: Hydrocephalus, a common brain disorder in children, can cause permanent brain damage. A timely diagnosis of this disorder is crucial. Objective: The aim of this study was to evaluate the levels of S-100, CK-18, and NSE brainspecific proteins in patients with hydrocephalus. We examined the levels of these proteins in the blood samples of hydrocephalic patients. Methods: The study was conducted on the hyd Read More

The extracts and the compounds isolated from Phyllanthus amarus Schumm and Thonn (Family: Euphorbiaceae) have shown a wide spectrum of pharmacological activities including antiviral, antibacterial, antiplasmodial, antimalarial, antimicrobial, anticancer, antidiabetic, hypolipidemic, antioxidant, hepatoprotective, nephroprotective and diurectic properties. Background: This investigation was aimed at exploring the anx Read More

Background: Tumor heterogeneity imposes great challenges on cancer treatment. Cancer stem cells (CSCs) are a leading factor contributing to tumor occurrence. However, the mechanisms underlying the growth of thyroid cancer (TCHA) are still unclear. Methods: Key genes regulating the characteristics of THCA, such as stemness were identified by combining gene expressions of samples downloaded from the Cancer Gen Read More

Aim: The aim of this study was to investigate the efficacy of thiol disulfide homeostasis and Ischemia Modified Albumin (IMA) values in predicting the technical difficulties that might be encountered during laparoscopic cholecystectomy. Materials and Methods: The study included 65 patients who underwent laparoscopic cholecystectomy due to cholelithiasis at the General Surgery Clinic of Ankara Numune Training and Research H Read More

Background: Coronavirus Disease 2019 (COVID-19) pandemic continues to threaten patients, societies and healthcare systems around the world. There is an urgent need to search for possible medications. Objective: This article intends to use virtual screening and molecular docking methods to find potential inhibitors from existing drugs that can respond to COVID-19. Methods: To take part in the current research investigation Read More

Background: One of the principal factors in the field of research in green chemistry is to drive chemical reactions using ultrasonication as a versatile synthetic tool. Moreover, nanostructured metal salts occupy an important position as low cost, efficient, heterogeneous, and green catalysts in chemical reactions. Pyrimidine has also acquired significance because it is a core structure in a variety of natural and non-n Read More

Aims & Objective: Armoracia rusticana has high medicinal values and is an excellent source of phytochemicals. This study was aimed to evaluate the antidiabetic potential of bioactive compounds from Armoracia rusticana. Methods: The antidiabetic analysis revealed that Armoracia rusticana was highly active against α glucosidase with IC50 values of 5.6 μg/ml. Furthermore, molecular docking was used to identify the active co Read More

Background: Cervical cancer (CESC), which threatens the health of women, has a very high recurrence rate. Purposes: This study aimed to identify the signature long non-coding RNAs (lncRNAs) associated with the prognosis of CESC and predict the prognostic survival rate with the clinical risk factors. Methods: The CESC gene expression profiling data were downloaded from TCGA database and NCBI Gene Expression Omnibus. Read More
