Phenol-driven ammonium recovery from coal chemical wastewater in a bioelectrochemical system (BES).

Bioelectrochemical systems (BES) have gained considerable attention in the past decade as a potentially sustainable and cost-effective method for coal chemical wastewater (CCW) treatment. However, a scarcity of studies focusing on the recovery NH-N in the recycling treatment of CCW via BES technology. In this study, a BES-ammonium recovery system (BES-ARS) was proposed to remove phenol and NH-N simultaneously, while NH-N was further recovered in a downstream recovery unit.

Mechanisms of action and adaptive responses to diclofenac and meloxicam during the early life stages of Oryzias melastigma.

Non-steroidal anti-inflammatory drugs (NSAIDs), though designed to target specific molecular pathways, pose significant environmental risks to non-target organisms, particularly marine fish. This study investigated the toxicity mechanisms and adaptive responses to diclofenac (DCF) and meloxicam (MEX) during the early life stages (ELS) of Oryzias melastigma at environmentally relevant concentrations over a 31-day period. Mechanistic investigations of sub-lethal effects were conducted using Enzyme-Linked Immunosorbent Assay (ELISA), RNA sequencing (RNA-Seq) and quantitative PCR (qPCR).

Efficacy and Safety of Low-Dose Lenvatinib and Toripalimab in Patients With Recurrent Platinum-Resistant Ovarian Cancer: Study Protocol of a Multicenter, Open-Label, Single-Arm, Phase II Clinical Trial.

Purpose: Therapeutic options for patients with platinum-resistant ovarian cancer (PROC) remain a major unmet need. PROC patients with multiple recurrences are unable to continue highly toxic treatment after prior multiple lines of systemic therapy. Chemotherapy-free option lenvatinib plus anti-programmed cell death protein-1 (PD-1) combination therapy has shown promising results in several malignancies including ovarian cancer, but the toxicity of a high starting dose of lenvatinib is also notable and needs to be improved.

NEK6 functions as an oncogene to promote the proliferation and metastasis of ovarian cancer.

Ovarian cancer (OC) is a common malignant tumor of the female reproductive organs. The novel serine/threonine kinase NEK6 is highly expressed in various cancers and affects the prognosis of patients. However, the role of NEK6 in OC is still unclear.

Rectifying the Crosstalk between the Skeletal and Immune Systems Improves Osteoporosis Treatment by Core-Shell Nanocapsules.

Contemporary osteoporosis treatment often neglects the intricate interactions among immune cells, signaling proteins, and cytokines within the osteoporotic microenvironment. Here, we developed core-shell nanocapsules composed of a cationized lactoferrin core and an alendronate polymer shell. By tuning the size of these nanocapsules and leveraging the alendronate shell, we enabled precise delivery of small interfering RNA targeting the Semaphorin 4D gene (siSema4D) to specific bone sites.

Microneedle-delivered adeno-associated virus vaccine amplified anti-viral immunity by improving antigen-presenting cells infection.

Adeno-associated viruses (AAV) have significant potential as vaccine carriers due to their excellent biosafety and efficient antigen gene delivery. However, most AAV vaccines show limited capacity to transduce antigen-presenting cells (APCs) following intramuscular injection which may cause inadequate cellular immune responses and undesired side effects due to transducing other tissues or cells. Herein, we developed a soluble microneedle patch for targeting the AAV vaccines to the epidermal and dermal APCs.

A Universal Therapeutic Vaccine Leveraging Autologous Pre-Existing Immunity to Eliminate in Situ Uniformly Engineered Heterogeneous Tumor Cells.

Tumor vaccines that activate the autologous immune system to eliminate tumor cells represent a promising approach in cancer immunotherapy. However, challenges such as tumor heterogeneity, limited antigen selection, insufficient antigen presentation, and the slow onset of de novo immune responses have resulted in poor universality and suboptimal response rates. In contrast, pathogen-specific pre-existing immunity acquired through infection or vaccination, can rapidly generate a more potent and enduring immune response upon re-encounter with the same antigen.

Metalloparticle-Engineered Pickering Emulsion Displaying AAV-Vectored Vaccine for Enhancing Antigen Expression and Immunogenicity Against Pathogens.

Recombinant adeno-associated viruses (rAAVs) have emerged as promising vaccine vectors due to their enduring efficacy with a single dose. However, insufficient cellular immune responses and the random and non-specific distribution of AAVs post-injection may hinder the development of AAV vaccines. Here, a novel Pickering emulsion platform stabilized by biomineralized manganese nanoparticles and aluminum hydroxide, which can rapidly and efficiently load AAVs, is reported.

Antigens and adjuvants co-stabilized Pickering emulsions amplify immune responses of subunit vaccines.

Most subunit antigens often induce suboptimal vaccination efficacy, possibly due to their low immunogenicity and limited ability to migrate to lymph nodes (LNs). Although the emergence of nanovaccine has significantly addressed these challenges, most formulations still require specific biological or chemical modifications to the carrier or antigen for efficient antigen loading. In this study, we report a Pickering emulsion-based nanovaccine that directly utilized antigens and adjuvants as stabilizers, effectively amplifying immune responses without additional physicochemical alterations.

Application of a 3D Fusion Model to Evaluate the Efficacy of Clear Aligner Therapy in Malocclusion Patients: Prospective Observational Study.

Background: Investigating the safe range of orthodontic tooth movement is essential for maintaining oral and maxillofacial stability posttreatment. Although clear aligners rely on pretreatment digital models, their effect on periodontal hard tissues remains uncertain. By integrating cone beam computed tomography-derived cervical and root data with crown data from digital intraoral scans, a 3D fusion model may enhance precision and safety.

Multidisciplinary Approach Improves Eradication Rate and Safety in Refractory Helicobacter pylori Infection.

Introduction: Helicobacter pylori (HP) infection is prevalent worldwide and contributes to various gastrointestinal diseases. Eradication therapy is crucial in managing HP infection, but antibiotic resistance has led to refractory cases, complicating treatment outcomes and increasing the risk of adverse events. This study aimed to evaluate the effectiveness of a multidisciplinary approach, termed HP Multidisciplinary Team (MDT) Clinic, in improving eradication rates and safety in patients with refractory HP infection.
