Article Synopsis
  • COVID-19 patients showed increased rates of delirium, prompting a study to evaluate the impact of structured nursing interventions on reducing this incidence.
  • In a study involving 168 COVID-19 patients, those receiving multidimensional interventions experienced a significantly lower rate of delirium (10.50%) compared to the control group (25.30%).
  • Overall, the findings indicate that tailored nursing measures can effectively decrease delirium among COVID-19 patients, although the duration of delirium and hospital stay did not show significant differences between groups.

The neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR), derived neutrophil-to-lymphocyte ratio (dNLR), neutrophil-to-lymphocyte and platelet ratio (N/LP ratio), aggregate index of systemic inflammation (AISI), systemic inflammation response index (SIRI), and systemic inflammation index (SII) have emerged as noteworthy determinants in evaluating the severity and mortality prognosis of inflammatory diseases. In order to predict mortality rate, this study aimed to assess the impact of systemic inflammatory markers on both men and women who were admitted to the hospital due to SARS-CoV-2 infection. The laboratory parameters of the 2007 COVID-19 patients were analyzed in a retrospective study (men = 1145 and women = 862).

Titanium dioxide nanoparticles: a promising candidate for wound healing applications.

Burns Trauma

January 2025

Research Group of Immune Cell Communication, Department of Immune Medicine, Universitätsklinikum Regensburg | UKR, Franz-Josef-Strauss-Allee 11, 93053, Regensburg, Germany.

Effective wound management and treatment are crucial in clinical practice, yet existing strategies often fall short in fully addressing the complexities of skin wound healing. Recent advancements in tissue engineering have introduced innovative approaches, particularly through the use of nanobiomaterials, to enhance the healing process. In this context, titanium dioxide nanoparticles (TiO NPs) have garnered attention due to their excellent biological properties, including antioxidant, anti-inflammatory, and antimicrobial properties.

Uncertain choices with asymmetric information: how clear evidence and ambiguity interact?

Front Psychol

December 2024

Control and Intelligent Processing Centre of Excellence, School of Electrical and Computer Engineering, College of Engineering, University of Tehran, Tehran, Iran.

Real-world decisions often involve partial ambiguity, where the complete picture of potential risks is unclear. In such situations, individuals must make choices by balancing the value of available information against the uncertainty of unknown risks. Our study investigates this challenge by examining how people navigate the trade-off between the favorability of limited evidence and the degree of ambiguity when making decisions under partial ambiguity.

Article Synopsis
  • The study focused on dissimilar laser welding of AISI 1060 carbon steel and Duplex Stainless Steel 2205, using both experimental and numerical methods to analyze the impact of welding parameters.
  • The increase in laser power significantly influenced the melt pool depth, which rose from 0.4 mm to 1.4 mm when power was ramped up from 250 to 450 W, and the resultant microstructure varied between the two materials with distinct solidification patterns.
  • Tensile test results indicated that the carbon steel side exhibited brittle fracture, while the Duplex Stainless Steel showed a ductile fracture, highlighting the differing mechanical properties due to their respective microstructures and the transition towards ductility with increased laser energy density.

A magnetic nano-composite coagulant has been designed, originally applied in a specific industrial waste-water treatment, and statistically investigated using Central Composite Design (CCD). The generated polynomial models were utilized to achieve a comprehensive understanding of the impact of each ingredient of PolyAluminum Chloride (PAC), PolyAcrylAmide (PAM), and Iron (III) oxide magnetic nano particles (MNP) regarding optimum limits and conditions. The concentration of each of those components has been considered as the main effective factors, which are found to be significantly correlated, affecting the Total Dissolved Solid (TDS) removal (%), the Total Suspended Solid (TSS) removal (%), and the Turbidity Reduction Rate (TRR) NTU/min.

In this article, the propagation of high-frequency (HF) plane electromagnetic waves through the lower ionosphere is numerically investigated using the real geometry of the Earth's magnetic field in the northern hemisphere. For this purpose, the profiles of electron density and the collision frequency in the layers of the lower ionosphere (D- and E-region) are considered using the reported experimental data for day and night. The reflection, transmission, and absorption coefficients of HF radio waves in the frequency range of 3 to 30 MHz are calculated in the ionosphere plasma.
