Article Synopsis
  • Bone tissue engineering is being explored as an alternative to traditional bone grafting, and this study focuses on using graphene quantum dots (GQDs) to enhance the process.
  • Human Wharton's jelly-derived mesenchymal stem cells (hWJ-MSCs) were combined with a fibrin hydrogel scaffold containing varying concentrations of GQDs.

The burgeoning field of nano-bone regeneration is yet to establish a definitive optimal particle size for nanocarriers. This study investigated the impacts of nanocarrier's particle size on the bone regeneration efficacy of fingolimod (FTY720)-loaded nanoemulsions. Two distinct particle sizes (60 and 190 nm, designated as NF60 and NF190, respectively) were produced using low-energy and high-energy emulsion techniques, maintaining a consistent surfactant, co-surfactant, and oil.

Oil transformers are one of the most widely used and vital equipment in power distribution networks. Therefore, in order to maintain the service of the electricity distribution system, special attention should be paid to the health and repairs of these equipment's in order to avoid possible costs due to their failure. Since the mineral oil used in these transformers is one of the strongest insulators, it needs a series of maintenance and periodic tests to increase the lifespan of the transformer.

This research introduces a new "turn-on mode" fluorescence sensor for the detection of fenitrothion (FNT) pesticide in various samples. The sensor is constructed using a porous metal-organic framework (Fe-BTC) as a template to locate silver nanoparticles (AgNPs) and methionine amino acid (Meth). Methionine acts as a bridge, facilitating the interaction between FNT and AgNPs, which subsequently results in the release of AgNPs from the composite structure.

Biopolymers offer significant advantages in water treatment applications. This study investigates polyethersulfone (PES) membranes enhanced with TiO₂ and Fe₃O₄ nanoparticles modified by sodium alginate (NaAlg), abbreviated as NaAlg@TiO₂ and NaAlg@Fe₃O₄, for the removal of diclofenac sodium salt (DCF) from water. The NaAlg biopolymer modification was achieved by wrapping the metal oxide nanoparticles.

Neural sensitization can cause neuroinflammation, which is a type of inflammation that occurs in both the peripheral nervous system and central nervous system. The purpose of this study was to investigate the effect of dimethyl itaconate (DMI) on the expression of NGFI-A and NGFI-B and inflammatory cytokines in the spinal cord in the formalin test. The rats were divided into five groups: control, formalin, DMI 10 mg/kg + formalin, DMI 20 mg/kg + formalin and diclofenac sodium 10 mg/kg + formalin.

Introduction: Self-assembling peptide nanofibers have emerged as promising biomaterials in the realm of bone tissue engineering due to their biocompatibility, biodegradability, and ability to mimic the native extracellular matrix. This study delved into the comparative efficacy of two distinct self-assembling peptide nanofibers, RADA-BMHP1 and KSL-BMHP1, both incorporating the biological motif of BMHP1, but differing in their core peptide sequences.

Methods: Cell viability and osteogenic differentiation in rat mesenchymal stem cells (rMSCs), and bone regeneration in rat were compared.

Background: Over the past few years, the sport psychology literature has established that gender stereotype threat (ST) is one of the factors that can impair girls' performance. However, few studies have attempted to annihilate these negative effects. The purpose of the current study was to investigate whether questioning gender ST can mitigate the classical decline in girls' standing long jump (SLJ) performance.

Article Synopsis
  • Future climate changes will lead to more extreme weather, negatively affecting crop yields and quality, particularly due to heat stress, which is less understood for grain quality.
  • A study on safflower plants with different heat tolerances revealed that extreme heat reduced seed yield by 53-57% and altered fatty acid composition, with increases in saturated fatty acids and varying effects on unsaturated fatty acids over two years.
  • Heat stress impacted the physicochemical properties of safflower oil more significantly than the fatty acid profile, showing that certain parameters fluctuated based on environmental conditions and genetic tolerance.

Background: An importance of tillage, inorganic and organic nutrient sources in the mustard - soybean cropping system lies in their ability to enhance soil fertility, improve nutrient availability, optimize crop growth and yield, and promote sustainable agricultural practices. Any cropping system's sustainability could be increased by implementing better management techniques like zero and reduced tillage with residue retention and better nutrient sources.

Results: A field experiment was conducted for four consecutive seasons (Winter 2019 to Rainy 2021) to compare the two enhanced management practices, zero and reduced tillage to conventional tillage across four levels of nutrient sources: 75 and 100% recommended dose of nitrogen through FYM and 75 and 100% recommended dose of fertilizers through urea, single super phosphate and muriate of potash in a two years experiment.

Autophagy, the lysosome-driven breakdown of intracellular components, is pivotal in regulating eukaryotic cellular processes and maintaining homeostasis, making it physiologically important even under normal conditions. Cellular mechanisms involving autophagy include the response to nutrient deprivation, intracellular quality control, early development, and cell differentiation. Despite its established health significance, the role of autophagy in cancer and other diseases remains complex and not fully understood.

Monolayer jacutingaite (PtHgSe) exhibits remarkable properties, including significant spin-orbit coupling (SOC) and a tunable band gap, attributed to its buckled honeycomb geometry and the presence of heavy atoms. In this study, we explore the spin- and valley-dependent anomalous Nernst effect (ANE) in jacutingaite under the influence of a vertical electric field, off-resonance circularly polarized light (OCPL), and an antiferromagnetic exchange field. Our findings, within the low-energy approximation, reveal the emergence of a perfectly spin-polarized ANE with the application of appropriate OCPL and a perfectly valley-polarized ANE under an antiferromagnetic exchange field.
