Highly crystallized Co and CoO nanoparticles embedded in an N-doped amorphous carbon matrix have been successfully fabricated by the molten-salt-assisted method using KClO and zeolitic imidazolate framework-12 (ZIF-12). Pyrolysis of ZIF-12 with different concentrations of KClO leads to embedded Co and CoO nanoparticles in a conductive amorphous carbon network. The impact of salt concentration on the morphology and electrochemical performance of these composites was investigated for electrochemical sensor applications.

Article Synopsis
  • Nurse leaders are under significant pressure, and developing self-leadership skills is crucial for nursing students to succeed before graduation.
  • The study investigated nursing students' self-leadership perceptions and identified factors that influence these perceptions through surveys and focus group interviews.
  • Results indicated that employment, involvement in organizations, and career goals enhance self-leadership, while barriers include comfort zones, overthinking, and procrastination; recommendations were made for nurse educators to create supportive interventions for skill development.

In this work, we report a study examining how different salt concentrations affect the structure and electrochemical performance of two CoO/C materials designed for the fabrication of an easy, cheap, fast, safe, and useful electrochemical sensor for the detection of Palbociclib (PLB). CoO nanoparticles were successfully created by encapsulating them in N-doped amorphous carbon matrices by using the molten salt-assisted approach. In this process, different amounts of potassium iodate and zeolitic imidazolate framework-12 (ZIF-12) were used, followed by pyrolysis at 800 °C.

The successful fabrication is reported of highly crystalline Co nanoparticles interconnected with zeolitic imidazolate framework (ZIF-12) -based amorphous porous carbon using the molten-salt-assisted approach utilizing NaCl. Single crystal diffractometers (XRD), and X-ray photoelectron spectroscopy (XPS) analyses confirm the codoped amorphous carbon structure. Crystallite size was calculated by Scherrer (34 nm) and Williamson-Hall models (42 nm).

Article Synopsis
  • The study investigates the effectiveness of two brain tumor perfusion MRI techniques: dynamic susceptibility contrast-enhanced (DSC) and arterial spin labeling (ASL), focusing on their qualitative and quantitative diagnostic capabilities.
  • A total of 90 patients treated for malignant brain tumors were analyzed, with imaged perfusion data being categorized into treatment-related changes or relapse/residual mass.
  • Results show that DSC and ASL values are generally higher in relapse cases than in treatment-related changes, with strong correlations between the techniques, indicating potential overlapping effectiveness in diagnosis.

Background: Inflammation occurring after vascular endothelial damage plays a role in thrombus formation. Changes in various blood parameters that develop after the inflammatory condition can be used as a marker to predict thrombus.

Aim: This study aimed to investigate the relationship between the neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), and portal vein thrombosis (PVT).

Purpose: Obstructive sleep apnea (OSA) is a common clinical condition in which the upper airway partially or completely narrows or collapses during sleep. The objective of our research was to examine the relation between the abnormal internal carotid artery (ICA) and the pharyngeal wall among individuals suffering from OSA, and to compare it to a group of control subjects.

Methods: In this retrospective study, the closest distances of the ICA to the pharyngeal walls and midlines were measured on CT images and compared between groups.

Practices that strengthen nurse work environments and enable them to have control over nursing practices have gained importance in recent years as they increase nurses' retention and patient care quality. This study aimed to examine the relationships between structural empowerment and nurse and patient-reported outcomes and the mediating role of control over nursing practices in these relationships. This correlational and cross-sectional study was carried out from September 2018 to May 2019 at two public hospitals in Turkey.

Although the etiopathogenesis of Behçet's disease is not known, studies conducted in different populations show that it is a multifactorial disease that is thought to develop as a result of the interaction of environmental and genetic factors. IL-17 is thought to induce the neutrophilic inflammation and the tissue damage mediated by immune response in patients. Polymorphisms in the gene region encoding IL-17 and IL-17R molecules may play a critical role in the pathogenesis of the disease and contribute to the elucidation of disease mechanism.

Non-covalent functionalization of single wall carbon nanotubes (SWCNTs) has been conducted using several binding agents with surface π-interaction forces in recent studies. Herein, we present the first example of non-covalent functionalization of sidewalls of SWCNTs using thienothiophene (TT) derivatives without requiring any binding agents. Synthesized TT derivatives, TT-CN-TPA, TT-CN-TPA2 and TT-COOH-TPA, were attached directly to SWCNTs through non-covalent interactions to obtain new TT-based SWCNT hybrids, HYBRID 1-3.

Actinic lichen planus (ALP) that affects sun-exposed areas of the skin is an uncommon variant of lichen planus. While ALP is commonly triggered by ultraviolet radiation exposure, genetic predisposition may also be important in the pathogenesis of the disease. Herein, we report three patients with ALP from the same family, which supports the genetic etiopathogenetic factors of ALP.
