Intrinsically photosensitive polyimide photoresist and its double crosslinking mechanism.

A new negative-working photoinitiator-free polyimide was developed for photolithographic processes. The polyimide introduced a photosensitive benzophenone unit into the backbone and a cross-linking group (methacrylate) into the side chains. A novel pre-functionalized diamine monomer was designed to avoid using corrosive sulfonyl chloride in the polyimide side-chain introduction step.

Dental Pulp Stem Cell Lysate-Based Hydrogel Improves Diabetic Wound Healing via the Regulation of Anti-Inflammatory Macrophages and Keratinocytes.

The prolonged existence of chronic wounds heightens the risk of patients experiencing chronic pain, necrosis, and amputation. Dental pulp stem cells (DPSCs) have garnered attention due to their potential immunomodulatory and tissue repair regenerative effects in the management of chronic wounds. However, stem-cell-based therapy faces challenges such as malignant differentiation, immune rejection, and long-term effectiveness.

Photonic Microbead Array Digital Time-Resolved Fluorescence Ultrasensitive Platform for Simultaneous Detection of Multiple Mycotoxins.

Limitations in the sensitivity, linear detection range, and cross-reaction of lateral flow immunoassays mainly hamper their application in rapid screening for multiple targets. In this work, we designed a new time-resolved fluorescence immunoassay (TRFIA) platform to overcome these limitations. This platform uses europium chelate polystyrene (PS@Eu) nanoparticles conjugated with monoclonal antibodies to sense multiple mycotoxins.

Methods: A case-control investigation was conducted in Anhui Province from March 2021 to December 2022.

Imaging findings of type I neurofibromatosis with outcome of malignant peripheral nerve sheath tumor in the right lower extremity.

Neurofibromatosis type 1 (NF1) is an autosomal dominant disorder caused by mutations of the NF1 tumor suppressor gene, characterized by café-au-lait spots, neurofibromas, and Lisch nodules. Malignant peripheral nerve sheath tumor (MPNST) is an extremely rare malignancy with neural differentiation potential. The lifetime risk of developing MPNST in NF-1 patients is 8%-13%.

Enhancing biofilm formation with powder carriers for efficient nitrogen and phosphorus removal.

This study assesses the improvement in nitrogen and phosphorus removal from wastewater achieved through the integration of zeolite and attapulgite carrier materials into the activated sludge (AS) process. It was found that the addition of these materials significantly enhanced the processing performance of the reactor. Specifically, the use of zeolite and attapulgite powders increased sludge particle sizes to averages of 231.

Pharmacological effects and the related mechanism of scutellarin on inflammation-related diseases: a review.

Inflammation is a biological response of multicellular organisms caused by injuries, pathogens or irritants. An excessive inflammatory response can lead to tissue damage and various chronic diseases. Chronic inflammation is a common feature of many diseases, making the search for drugs to treat inflammation-related diseases urgent.

Exploring the antimicrobial activity of rare ginsenosides and the progress of their related pharmacological effects.

Background: Panax ginseng C. A. Mey is a precious medicinal resource that could be used to treat a variety of diseases.

Injectable citrate-based polyurethane-urea as a tug-of-war-inspired bioactive self-expansive and planar-fixing screw augmented bone-tendon healing.

Inspired by tug-of-war, a game-changing bone-tendon fixation paradigm was developed. Specifically, injectable citrate-based bioactive self-expansive and planar-fixing screw (iCSP-Scr) consisting of reactive isocyanate (NCO) terminalized citrate-based polyurethane, proanthocyanidin modified hydroxyapatite (HAp) and water (with/without porogen) was developed and administrated in the bone-tendon gap. Instead of the "point to point" tendon fixation by traditional interface screws, along with the moisture-induced crosslinking and expansion of iCSP-Scr within the confined space of the irregularly shaped bone-tendon gap, the tendon graft was evenly squeezed into the bone tunnel in a "surface to surface" manner to realize strong and stable bone-tendon fixation via physical expansion, mechanical interlocking and chemical bonding (between -NCO and the -NH, -SH groups on bone matrix).

Improved therapeutic index of the liposomal docetaxel-glutathione prepared by active click loading.

The clinical usage of docetaxel (DTX) is severely hindered by the dose-limiting neutropenia and peripheral neurotoxicity of polysorbate 80-solubilized DTX injection, and there are no alternative formulations until now. In this study, we developed a new liposomal formulation of DTX to reduce its toxicities, accompanying with the greatly improved antitumor activity. The DTX was encapsulated into liposomes in the form of hydrophilic glutathione (GSH)-conjugated prodrugs using a click drug loading method, which achieved a high encapsulation efficiency (∼95 %) and loading capacity (∼30 % wt).

Nano-enabled regulation of DNA damage in tumor cells to enhance neoantigen-based pancreatic cancer immunotherapy.

Low-expression antigens, especially neoantigens, pose a significant challenge in immunotherapy for low immunogenicity pancreatic cancer. Increasing the tumor mutation burden is crucial to enhance the expression of tumor antigens and improve tumor immunogenicity. However, the incomplete intervention in DNA stability hampers effective elevation of the tumor mutation burden, thus reducing the probability of neoantigen.

Staphylococcal enterotoxin B exposed to pregnant rats inhibits the hedgehog signaling pathway in thymic T lymphocytes of the offspring.

The Hedgehog (Hh) signaling pathway is involved in T cell differentiation and development and plays a major regulatory part in different stages of T cell development. A previous study by us suggested that prenatal exposure to staphylococcal enterotoxin B (SEB) changed the percentages of T cell subpopulation in the offspring thymus. However, it is unclear whether prenatal SEB exposure impacts the Hh signaling pathway in thymic T cells.
