Multifunctional dual-layer wound dressings hold significant promise for comprehensive full-thickness wound management by closely mimicking the native skin structure and features. Herein, we employed an innovative approach utilizing electrospinning techniques to develop a dual-layer dressing comprising a microfibrous Ecoflex®-Vanillin (Ex-Vnil) top layer (TL) and a nanofibrous Soluplus®-Insulin-like growth factor-1 (Sol-IGF1) bottom layer (BL). The tensile properties of dual-layer wound dressings were within the standard range for use in skin tissue regeneration.

January 2025

Department of Food Science and Technology, Faculty of Agriculture, Ferdowsi University of Mashhad, Azadi Sq., Mashhad, Khorasan Razavi P.O. Box 9177948944, Iran. Electronic address:

Protein fibrillation complex mechanisms led to an emerging trend in research for years. The mechanisms behind whey protein isolate (WPI) fibrillation driven by divalent cations remained still a matter of speculation. All cations (Ca, Fe, Mg, and Zn) enhanced the microenvironment polarity through π-π stacking, and the amide I and II shifts confirmed the fibrillation.

Active Learning (AL) represents a transformative instructional approach that departs from traditional methods by immersing students in experiential learning activities such as problem-solving, discussions, role-plays, interactive engagement, and case studies. Despite its widely recognized potential, the effects of AL on psycho-affective constructs in English as a Foreign Language (EFL) contexts remain underexplored. Hence, this study explored the impact of AL on EFL learners' motivation, attitudes, and anxiety in Iran.

Using direct method to estimate calcium digestibility of barley and soybean meal in quail chicks.

Poult Sci

January 2025

Department of Animal Sciences, Faculty of Agriculture, University of Zabol, Sistan 98661-5538, Iran. Electronic address:

The availability of calcium (Ca) in poultry diets is influenced by various factors, such as the feed ingredients used. This study assessed the apparent ileal digestibility (AID) and standardized ileal digestibility (SID) of Ca in barley and soybean meal (SBM) in young quail chicks using a direct method. Three diets were formulated, including a Ca-free basal diet to evaluate ileal endogenous calcium losses (IECaL), and two diets with barley or SBM as the sole Ca sources.

Background: The pathogenesis of colorectal cancer (CRC) is influenced by various risk factors, and genetic alterations in progression of colon polyps. The expression patterns of microRNA-548 (miR-548) in colorectal tissues have been sufficiently characterized. The aim of this study is to clarify the role of miR-548aa in tumorigenesis, gene targeting, predictive value and its expression levels in tumoral versus adjacent marginal tissues in CRC patients.

Aging adversely affects the self-renewal and differentiation capabilities of stem cells, which impairs tissue regeneration as well as the homeostasis. Epigenetic mechanisms, specifically DNA methylation, play a key role in the maintenance of pluripotency in stem cells and regulation of pluripotency-related gene expression. Age-related modifications in methylation patterns could influence the expression of genes critical for stem cell potency maintenance, including transcription factors Nanog and Sox2.

The two-spotted spider mite, Tetranychus urticae Koch (Acari: Tetranychidae), is a major pest of various plants with a worldwide distribution. Extensive use of chemical pesticides has led to the development of resistance in this pest, making biological control agents a viable alternative for its management. The predatory mites, Neoseiulus californicus (McGregor) and Phytoseiulus persimilis Athias-Henriot (Acari: Phytoseiidae) are the most important predators of the two-spotted spider mites.

Department of Horticulture, Agriculture Faculty of Aburaihan, University of Tehran, P.O. Box 11365/4117, Tehran, Iran.

This research was conducted to determine the relationship between plant defense responses and the extent of treatment applied to either the aerial parts or roots of the plant. The experimental treatments included different methods of application (spraying versus soil drenching), varying treatment areas (one-sixth, one-third, half, or all of the plant's aerial parts and roots) with SA, and infecting the plants with root-knot nematodes. Evaluation of plant growth and nematode pathogenicity indices in the greenhouse section, HO accumulation rate, and phenylalanine ammonia lyase enzyme activity (in aerial parts and roots) were carried out in biochemical experiments.

MILs (Materials Institute Lavoisier), as nanocarriers based on metal-organic frameworks (MOFs), are one of the most advanced drug delivery vehicles that are now a major part of cancer treatment research. This review article highlights the key features and components of MIL nanocarriers for the development and improvement of these nanocarriers for drug delivery. Surface coatings are one of the key components of MIL nanocarriers, which play the role of stabilizing the nanocarrier, pH-dependent drug release, increasing the half-life of the drug, and targeting the carrier.

Understanding the neural mechanisms underlying emotional processing is critical for advancing neuroscience and mental health interventions. This study examined these mechanisms by analyzing EEG connectivity patterns across different brain regions while participants evoked various emotions. After applying independent component analysis (ICA) to eliminate non-cortical activity, we assessed frequency-specific connectivity patterns using coherence, Granger causality, and graph theoretical measures to evaluate both functional and effective connectivity.

This paper introduces an analytical method for studying power transmission through an infinite array of helical-shaped metal particles in a lossy dielectric medium. While the assessment of composite slabs' transmitted power has been extensively researched in the electromagnetic interference (EMI) shielding field, many studies lack an adequate problem description. The primary inadequacy of these studies is the need for an analytical framework.

In this study, a series of experiments are done to analyze the effect of bluff body geometry on the NO reduction of a natural gas-air stratified swirl burner. The stratified burner of Cambridge University is chosen to study the mentioned geometrical effect, and the geometry modification of bluff body is used as a simple method for NO reduction, which can be easily applied to the systems using these burners, including gas turbines. The bluff body geometrical change to an annular bluff body is inspired by the fact that the areas in which the edge of the bluff body is in contact with the unburned flow have lower temperatures, which can drastically affect combustion parameters, especially emissions.
