Navigating transition shock: The role of system thinking in enhancing nursing process competency among early career nurses.

Background: Building nursing process competency among beginner nurses is a pivotal need in contemporary, complex, fast-paced nursing practice. However, transitioning from the educational phase to practicing as a nurse can be a significant adjustment. New practitioners often experience a period of shock, which may present challenges in developing nurse competency.

The Relationship Between Defensive Pessimism, Goal Orientation, and Self-Esteem Among Nursing Students.

Introduction: Academic achievement in nursing students is significantly influenced by their self-esteem and goal orientation. Defensive pessimism, a strategy where students set low expectations to prepare for potential failure, helps them stay motivated and focused. While this cognitive strategy can boost effort and performance, its relationship with self-esteem and goal orientation remains underexplored among nursing students, revealing a gap in understanding how these factors interact to influence academic success.

Hence, there is increasing interest for the application of ammonia as fuel in various energy storage devices, specifically solid oxide fuel cells (SOFCs), as it has the potential to be efficient and environmentally friendly. In addition, compared to other fuel cells, SOFCs fed with ammonia offer various benefits such as such as sustainability and safety.

The role of Empathy in the relationship between emotional support and caring behavior towards patients among intern nursing students.

Background: The empathic relationship between nursing students and patients allows them to understand and address caring behavior for patients. Appropriate emotional support equips them to overcome the complexities and difficulties inherent in patient care. This support cultivates resilience and self-awareness, enabling students to manage their emotions effectively and establish meaningful connections and caring with their patients.

The mediating role of cardiac patients' perception of nursing care on the relationship between kinesiophobia, anxiety and depression in rural hospitals: a cross-sectional study.

Background: Kinesiophobia could act as a significant barrier against physical activity following cardiac procedures worsening cardiovascular health problems and potentially leading to conditions like hospital-acquired anxiety and depression among patients with cardiovascular disease (CVD). Nurses are the vanguard health care team who can aid patients in taking proactive steps to overcome fear of movement following cardiac procedures.

Aim: The overarching aim is to investigate the relationship between kinesiophobia, anxiety and depression, and patients' perception of nursing care.

Hooked on technology: examining the co-occurrence of nomophobia and impulsive sensation seeking among nursing students.

Background: Nomophobia, the crippling fear of being disconnected from mobile devices, is a burgeoning global concern. Given the critical nature of the profession of nursing students, understanding nomophobia's prevalence and potential impacts on patient care and professional conductors becomes even more crucial.

Aim: This study explores the relationship between nomophobia and impulsive sensation-seeking among nursing students in Egypt.

Relationship between digital capabilities and academic performance: the mediating effect of self-efficacy.

Aims: To assess digital capabilities and academic performance among nursing students and investigate the mediating role of students' self-efficacy.

Background: In the context of education and technology, digital capabilities, self-efficacy, and academic performance among nursing students are interconnected concepts. Students who use their digital capabilities and competencies combined with their belief in the ability to efficiently perform learning tasks could improve their academic endeavors.

Determination of rivaroxaban by utilizing its quenching effect on acetoxymercuric fluorescein reagent in pharmaceutical preparations and in spiked biological matrices.

A simple, precise and inexpensive spectrofluorimetric method has been developed for assay of rivaroxaban raw material and its tablets. The method depends on the quenching effect of rivaroxaban on the fluorescence intensity of acetoxymercuric fluorescein (AMF). Parameters that may affect the reaction such as pH, AMF solution concentration, reaction time and diluting solvents were studied and optimized.

Structural, Magnetic, and AC Measurements of Nanoferrites/Graphene Composites.

As a contribution to the graphene-based nanoferrite composites, this article is intended to present Mn, Co, and Co-Mn nanoferrites for the preparation and investigation of such samples. Nanoparticles of Co ferrite, Mn ferrite, and Co-Mn ferrite were chemically synthesized by the coprecipitation method. The composites of ferrite/graphene were made by incorporating weight ratios of 25% graphene to 75% ferrite.

One pot synthesis of new cross-linked chitosan-Schiff' base: Characterization, and anti-proliferative activities.

Four novel chitosan hydrogels were successfully synthesized through the cross-linking reaction of chitosan with different concentrations of ethyl 5-(3,5-dihydroxy-1,4-dioxan-2-yl)-2-methylfuran-3-carboxylate. Their structures were confirmed by Fourier transform infrared spectroscopy (FT-IR), C Cross polarization magic angle spinning nuclear magnetic resonance spectroscopy (CP/MAS C NMR), ultraviolet-visible spectroscopy, thermogravimetric analysis (TGA, DTA), and X-ray diffraction (XRD). Cytotoxicity on hepatocellular carcinoma (HepG-2) cell line and a normal African green monkey kidney (Vero) cell line were studied using the MTT assay.

Kruppel-Like Factor 4 represses osteoblast differentiation via ciliary Hedgehog signaling.

Primary cilia are appendages observed in most types of cells, and serve as cellular antennae for sensing environmental signals. Evidence is accumulating that correct ciliogenesis and ciliary functions are indispensable for normal skeletal development by regulating signaling pathways important for bone development. However, whether ciliogenesis is regulated by bone-related factors in osteoblasts is largely unknown.

Kruppel-like factor 4 regulates matrix metalloproteinase and aggrecanase gene expression in chondrocytes.

Kruppel-like factor 4 (KLF4) is a zinc finger transcription factor that plays crucial roles during the development and maintenance of multiple organs. We and others have previously shown that KLF4 is involved in bone modeling and remodeling but roles played by KLF4 during skeletogenesis are still not fully understood. Here, we show that KLF4 is expressed in the epiphyseal growth plate and articular chondrocytes.

Fate mapping of Trps1 daughter cells during cardiac development using novel Trps1-Cre mice.

Tricho-rhino-phalangeal syndrome (TRPS) is a rare congenital disorder that is characterized by abnormal hair growth and skeletal deformities. These result in sparse hair, short stature, and early onset of joint problems. Recent reports have shown that a relatively high proportion of patients with TRPS exhibit a broad range of congenital heart defects.
