Methylene blue sorption performance of lignocellulosic peach kernel shells modified with cellulose derivative chitosan as a new bioadsorbent.

In this study, adsorption isotherms (Langmuir, Freundlich, Temkin, and Dubinin-Radushkevich) and thermodynamic properties of cationic methylene blue (MB) dye adsorption onto chitosan-coated peach kernel shell waste (CTS-PKSh) from wastewater were investigated. CTS was cross-linked with citric acid (CA) and glutaraldehyde (GA). The adsorbents were characterized by FE-SEM/EDS, FTIR, and particle size distribution.

Ultrasonic extraction of Inula viscosa: Enhancing antioxidant bioactivity and its application in sunflower oil as an antioxidant.

The objective of this study was to optimize the ultrasound-assisted extraction (UAE) of Inula viscosa, focusing on the extraction yield, total phenolic content (TPC), total flavonoid content (TFC), and antioxidant capacity and to evaluate its antioxidant effect in sunflower oil (SFO) storage. A water-ethanol binary solvent system was applied to extract bioactive components sustainably. Extraction parameters (temperature, time, ethanol concentration, and solvent-to-solid ratio) were optimized using a central composite rotatable design, achieving high accuracy (R > 0.

The Association between the Preoperative Prognostic Nutritional Index and the Controlling Nutritional Status Score on Tumor Stage, Chemotherapeutic Response and Overall Survival in Ovarian Cancer.

This study aimed to investigate the association between preoperative prognostic nutritional index (PNI) and controlling nutritional status (CONUT) scores on the stage of ovarian cancer (OC), chemotherapeutic response, and overall survival (OS) in patients with OC. The data of the patients who operated due to OC between January 2015 and January 2020 in a tertiary referral hospital were recorded. The patients' basic characteristics, preoperative total cholesterol, albumin, lymphocyte count, tumor markers, disease stage, grade, chemotherapeutic response, OS, and progression-free survival were recorded.

Immobilization of arrestin-3 on different biosensor platforms for evaluating GPCR binding.

G protein-coupled receptors (GPCRs) are a large and ubiquitous family of membrane receptors of great pharmacological interest. Cell-based assays are the primary tool for assessing GPCR interactions and activation but their design and intrinsic complexity limit their application. Biosensor-based assays that directly and specifically report GPCR-protein binding (e.

Polymer-Lipid Hybrid Membranes as a Model Platform to Drive Membrane-Cytochrome Interaction and Peroxidase-like Activity.

Controllable attachment of proteins to material surfaces is very attractive for many applications including biosensors, bioengineered scaffolds or drug screening. Especially, redox proteins have received considerable attention as a model system not only to understand the mechanism of electron transfer in biological systems, but also the development of novel biosensors. However, current research attempts suffer from denaturation of the protein after its attachment to solid substrates.

The predictive value of plasma osmolality for in-hospital mortality in patients with acute pulmonary embolism.

Introduction And Objectives: Prior studies demonstrated that plasma osmolality may have a predictive value for in-hospital mortality in patients with heart failure and acute coronary syndrome. In addition, plasma glucose and blood urea nitrogen (BUN) levels, the components of plasma osmolality, have been shown to be an important contributor for in-hospital mortality in acute pulmonary embolism (APE) patients. Hence, the objective of the current study is to evaluate the effect of plasma osmolality upon admission with in-hospital mortality in patients with APE.

Long term evaluation of electromechanical delay in patients with atrial septal defect after transcatheter closure.

Some studies have been showed that electromechanical delay, which may pose an increased tendency to atrial fibrillation, may prolong in patients with various clinical conditions. In addition, the electromechanical delay in patients with secundum type atrial septal defect (ASD) compared to healthy people have been reported previously. Therefore, in the present study, we prospectively evaluated the mid-term and long-term effects of the transcatheter closure of secundum type ASD on the lateral atrial conduction time (PA), septal PA, tricuspid PA, left and right intra-atrial electromechanical delay (ILeft-EMD and IRight-EMD, respectively) and inter-atrial electromechanical delay (IA-EMD) measured by means of Doppler echocardiography.

Acute myocardial infarction associated with clomiphene citrate in a young woman.

Clomiphene citrate is a drug that stimulates ovulation and is commonly used in cases of female infertility. Generally, it is recognized as a safe agent for ovulation induction, but rarely, it is associated with life-threatening conditions. A 36-year-old woman who had been prescribed clomiphene citrate for infertility was admitted to the emergency department for chest pain lasting for 2 hours.

Is Troponin really a reliable marker in patients with acute ischemic stroke?

Background And Purpose: Cardiac troponin I (cTnI) is a reliable marker to diagnose acute myocardial infarction, but the pathophysiological explanation for the increase in cTnI levels in patients with acute ischemic stroke (IS) remains unknown. To overcome this question, we aimed to compare serum cTnI levels in acute coronary syndrome (ACS) concomitant with and without stroke. By doing like this, we thought that we could demonstrate the effect of stroke on TrpI level.

Influence of natural organic matter (NOM) coatings on nanoparticle adsorption onto supported lipid bilayers.

As the worldwide usage of nanoparticles in commercial products continues to increase, there is growing concern about the environmental risks that nanoparticles pose to biological systems, including potential damage to cellular membranes. A detailed understanding of how different types of nanoparticles behave in environmentally relevant conditions is imperative for predicting and mitigating potential membrane-associated toxicities. Herein, we investigated the adsorption of two popular nanoparticles (silver and buckminsterfullerene) onto biomimetic supported lipid bilayers of varying membrane charge (positive and negative).

A novel prognostic indicator for in-hospital and 4-year outcomes in patients with pulmonary embolism: TIMI risk index.

Background: Thrombolysis in Myocardial Infarction (TIMI) risk index (TRI) was recently evaluated in patients with acute myocardial infarction and found as an important prognostic index. In the current study, we evaluated the prognostic value of TRI in patients with moderate-high and high risk pulmonary embolism (PE) who were treated with thrombolytic agents.

Methods: We retrospectively evaluated the in-hospital and long-term (4-year) prognostic impact of TRI in a total number of 456 patients with moderate-high and high risk PE.

Relation of the Number of Parity to Left Ventricular Diastolic Function in Pregnancy.

Left ventricular diastolic dysfunction (LVDD) has been relatively less studied than other cardiac changes during pregnancy. Previous studies revealed a mild diastolic deterioration during pregnancy. However, these studies did not evaluate the long-term effect of parity on left ventricular diastolic function.

Long-Term Antiarrhythmic Effects of Thrombolytic Therapy in Pulmonary Embolism.

Background: The role of thrombolytic therapy in acute pulmonary embolism patients is still controversial considering the occurrence of arrhythmias. Short-term effects of thrombolytics are well-known whereas long-term effects on cardiac electrophysiology have not been reported before. The objective of our study was to assess the arrhythmic differences in pulmonary embolism patients who received thrombolytics followed by anticoagulation or anticoagulation alone.
