Summary: Electrospun nanofibers have emerged as a promising option for wound dressings, with their high porosity, good mechanical properties, and excellent biocompatibility. They can promote wound healing by moisturizing the wound, facilitating cell respiration, and regenerating damaged skin. Furthermore, their ability to encapsulate active substances or incorporate them into their structural design allows them to meet the diverse requirements of wound therapy. This review article provides an overview of the recent developments in electrospun nanofibers as wound dressings, including the use of different polymer materials, their structural characteristics, and their role in promoting wound healing. The article also explores the future prospects of electrospinning in the development of wound dressings.

Summary: Injuries to the nervous system have significant impact worldwide. Artificial nerve guidance conduits (NGCs) provide a promising solution for nerve reconstruction but need to replicate the in vivo microenvironment. This study developed heparin/growth factors (GFs)-immobilized artificial NGCs, which showed successful retention and bioactivity of nerve growth factor (NGF). The NGCs demonstrated good stability and biocompatibility in vivo, suggesting their potential in nerve regeneration and tissue engineering.

Summary: A pyrolysis-free approach was used to create a catalyst with dual Ni/Fe atomic active sites, which exhibited efficient electrochemical water splitting in both acidic and alkaline electrolytes at low overpotentials. Catalysts capable of electrochemical overall water splitting in acidic, neutral, and alkaline solution are important materials. This work developed bifunctional catalysts with single atom active sites through a pyrolysis-free route, enhancing catalytic performance and providing insights into the catalytic processes. The as-prepared catalyst showed efficient catalytic capability for electrochemical water splitting in both acidic and alkaline electrolytes, making it a promising model catalyst for mechanistic studies.

Summary: This study investigated the intracellular delivery of fibronectin (FN) using phenylboronic acid (PBA)-functionalized generation 5 (G5) poly(amidoamine) dendrimers (G5.NH2-PBA) as nanocarriers. It was found that this method effectively guided macrophages towards anti-inflammatory M2 polarization. Mechanistic studies revealed that the dendrimer-mediated FN delivery suppressed the nuclear factor-κB pathway, resulting in reduced pro-inflammatory cytokine secretion and enhanced reactive oxygen species depletion. Furthermore, in vivo experiments demonstrated the potential of dendrimer-mediated FN delivery in alleviating lung inflammation and oxidative stress in acute lung injury.

Summary: Small interfering RNA (siRNA) shows potential in treating rheumatoid arthritis by inhibiting major cytokines like tumor necrosis factor-alpha (TNF-alpha). Researchers have developed original cationic amphiphilic phosphorus dendrons that can form dendriplexes with TNF-alpha siRNA. These dendriplexes protect siRNA from degradation and enhance macrophage uptake, leading to significant inhibition of TNF-alpha expression and anti-inflammatory effects in in vitro and in vivo models. This opens up important perspectives for using these original amphiphilic dendrons in chronic inflammatory diseases.

Summary: Dendrimers, including neutral, cationic or anionic phosphorus dendrimers, have a wide range of applications in nano sciences, biology, polymer science, catalysis, and nanomaterial formation. Their activity is highly dependent on their internal structure and the nature of their end groups. We have reported a novel multistep synthesis method with high yield to produce stable and hydrolysis-resistant neutral or anionic phosphorus dendrimers, opening up new possibilities for various applications including therapeutic use in areas such as cancer, inflammation, tuberculosis, and osteoclastogenesis.

Summary: ALV-J-SD1005 strain caused severe growth retardation, viremia, and subcutaneous fibrosarcomas in 1-day-old HY-Line Brown chickens. It increased the expressions of TRIM25, P53, etc., but decreased the expressions of 14-3-3a, etc. Overexpression of chTRIM25 promoted cell proliferation and improved the expressions of tumor factors P53, CDC2, and CDK2, while knockdown of chTRIM25 had the opposite effects. chTRIM25 can recognize and bind 14-3-3a protein in ALV-J-SD1005-infected cells, contributing to fibrous tissue hyperplasia.

Summary: Ultrasound-triggered sonodynamic therapy (SDT) has gained significant attention as a non-invasive and deep tissue penetration alternative for cancer treatment. However, the efficacy of SDT alone is limited by the hypoxic nature of solid tumors. Therefore, this study develops an intelligent theranostic nanoplatform that combines SDT and nitric oxide (NO) therapy to enhance cancer treatment.

Summary: This is a case of a patient with SLE complicated with cryptococcal meningitis. Due to the lack of specificity of clinical symptoms, it is easily misdiagnosed as neuropsychiatric lupus or tuberculous meningitis, leading to delayed treatment. Through this case, the early improvement of India ink stain of cerebrospinal fluid and metagenomic next generation sequences to identify microbial infection is suggested, along with early empirical anti-infection therapy.

Summary: In this study, PANI-ZnFe2O4/FAC composites were formed by coating zinc ferrate (ZnFe2O4) and polyaniline (PANI) on the surface of fly ash cenospheres (FAC) through hydrothermal and in situ polymerization using the floating property of FAC. Compared with other reference materials, the PANI-ZnFe2O4/FAC material not only solves the problem of less easy recycling, but also exhibits significantly enhanced photocatalytic activity for methylene blue (MB).
