Efficacy and safety of wet cupping in the treatment of neurodermatitis: a systematic review and meta-analysis.

Background: Neurodermatitis is a chronic skin condition characterized by intense itching and skin thickening due to neurological dysfunction. Its persistent nature poses a challenge to effective treatment, significantly impacting patients' quality of life. Wet cupping therapy is increasingly being used in clinics to manage neurodermatitis, so it is imperative to assess the evidence regarding its effectiveness and safety.

The journey of nanoparticles in the abdominal cavity: Exploring their in vivo fate and impact factors.

Peritoneal carcinomatosis (PC) is caused by metastasis of primary tumor cells from intra-abdominal organs to the peritoneal surface. Intraperitoneal (IP) chemotherapy allows close contact of high concentrations of therapeutic agents with cancer cells in the peritoneal cavity to prolong patient survival. However, conventional IP chemotherapy is prone to rapid elimination from the peritoneal cavity and lacks specificity towards cancer cells.

The role of ESM1 in the lipids metabolic reprogramming and angiogenesis of lung adenocarcinoma cells.

Background: Lung adenocarcinoma (LUAD) is one of the respiratory diseases with high mortality and incidence. As an important angiogenic factor, (Endothelial cell-specific molecule 1) ESM1 plays an important role in the occurrence and development of LUAD. However, the role and molecular mechanism of ESM1 on LUAD metabolic reprogramming and angiogenesis remain unclear.

Sodium glycocholate liposome encapsulated semaglutide increases oral bioavailability by promoting intestinal absorption.

The aim of this study was to prepare sodium glycocholate liposomes (SGC-Lip) encapsulating semaglutide (Sml) to improve oral bioavailability and better exert hypoglycemic effect. In this paper, SGC-Lip was prepared by reverse-phase evaporation method with particle size around 140 nm, potential around -27 mV, rounded morphology and better stability. The hypoglycemic and intestinal uptake effects of SGC-Lip and cholesterol-containing liposomes (CH-Lip) were comparatively investigated in rats, and the oral safety of SGC-Lip was examined by cytotoxicity assay.

Redox-sensitive disulfide-bridged self-assembled nanoparticles of dexamethasone with high drug loading for acute lung injury therapy.

Acute lung injury (ALI) arises from an excessive inflammatory response, usually progressing to acute respiratory distress syndrome (ARDS) if not promptly addressed. There is currently a limited array of effective treatments available for ALI. In this study, we developed disulfide bond-bridged prodrug self-assembled nanoparticles (referred to as DSSS NPs).

Milk Exosome-Liposome Hybrid Vesicles with Self-Adapting Surface Properties Overcome the Sequential Absorption Barriers for Oral Delivery of Peptides.

Milk exosomes (mExos) have demonstrated significant promise as vehicles for the oral administration of protein and peptide drugs owing to their superior capacity to traverse epithelial barriers. Nevertheless, certain challenges persist due to their intrinsic characteristics, including suboptimal drug loading efficiency, inadequate mucus penetration capability, and susceptibility to membrane protein loss. Herein, a hybrid vesicle with self-adaptive surface properties (mExos@DSPE-Hyd-PMPC) was designed by fusing functionalized liposomes with natural mExos, aiming to overcome the limitations associated with mExos and unlock their full potential in oral peptide delivery.

Topologically protected entanglement switching around exceptional points.

The robust operation of quantum entanglement states is crucial for applications in quantum information, computing, and communications. However, it has always been a great challenge to complete such a task because of decoherence and disorder. Here, we propose theoretically and demonstrate experimentally an effective scheme to realize robust operation of quantum entanglement states by designing quadruple degeneracy exceptional points.

Glucocorticoids-based prodrug design: Current strategies and research progress.

Attributing to their broad pharmacological effects encompassing anti-inflammation, antitoxin, and immunosuppression, glucocorticoids (GCs) are extensively utilized in the clinic for the treatment of diverse diseases such as lupus erythematosus, nephritis, arthritis, ulcerative colitis, asthma, keratitis, macular edema, and leukemia. However, long-term use often causes undesirable side effects, including metabolic disorders-induced Cushing's syndrome (buffalo back, full moon face, hyperglycemia, etc.), osteoporosis, aggravated infection, psychosis, glaucoma, and cataract.

Research on the loading and release kinetics of the vincristine sulfate liposomes and its anti-breast cancer activity.

Vincristine (VCR), as a cytotoxic drug, is used clinically to treat acute lymphatic leukemia and breast cancer, and commonly used clinically as vincristine sulfate (VCRS). However, its clinical use is limited by unpredictable pharmacologic characteristics, a narrow therapeutic index, and neurotoxicity. The pH gradient method was used for active drug loading of VCRS, and the process route mainly includes the preparation of blank liposomes and drug-loaded liposomes.

Effect of mPEG-PLGA on Drug Crystallinity and Release of Long-Acting Injection Microspheres: In Vitro and In Vivo Perspectives.

Purpose: Traditional progesterone (PRG) injections require long-term administration, leading to poor patient compliance. The emergence of long-acting injectable microspheres extends the release period to several days or even months. However, these microspheres often face challenges such as burst release and incomplete drug release.

Dual-Targeted Self-Adjuvant Heterocyclic Lipidoid@Polyester Hybrid Nanovaccines for Boosting Cancer Immunotherapy.

Tumor vaccines have demonstrated a modest response rate, primarily attributed to their inefficient delivery to dendritic cells (DCs), low cross-presentation, DC-intrinsic immunosuppressive signals, and an immunosuppressive tumor microenvironment (TME). Here, draining lymph node (DLN)-targeted and tumor-targeted nanovaccines were proposed to address these limitations, and heterocyclic lipidoid (A18) and polyester (BR647) were synthesized to achieve dual-targeted cancer immunotherapy. Meanwhile, oligo hyaluronic acid (HA) and DMG-PEG-Mannose were incorporated to prepare dual-targeted nanovaccines encapsulated with STAT3 siRNA and model antigens.

Aberrant angiogenic signaling pathways: Accomplices in ovarian cancer progression and treatment.

Ovarian cancer is one of the most common malignant tumors in women, and treatment options are limited. Despite efforts to adjust cancer treatment models and develop new methods, including tumor microenvironment (TME) therapy, more theoretical support is needed. Increasing attention is being given to antiangiogenic measures for TME treatment.

ESM1 enhances fatty acid synthesis and vascular mimicry in ovarian cancer by utilizing the PKM2-dependent warburg effect within the hypoxic tumor microenvironment.

Background: The hypoxic tumor microenvironment is a key factor that promotes metabolic reprogramming and vascular mimicry (VM) in ovarian cancer (OC) patients. ESM1, a secreted protein, plays an important role in promoting proliferation and angiogenesis in OC. However, the role of ESM1 in metabolic reprogramming and VM in the hypoxic microenvironment in OC patients has not been determined.

Effect of hydroxyethyl starch on drug stability and release of semaglutide in PLGA microspheres.

The degradation of peptide drugs limits the application of peptide drug microspheres. Structural changes of peptides at the water-oil interface and the destruction of their spatial structure in the complex microenvironment during polymer degradation can affect drug release and in vivo biological activity. This study demonstrates that adding hydroxyethyl starch (HES) to the internal aqueous phase (W) significantly enhances the stability of semaglutide and optimizes its release behavior in PLGA microspheres.

Distribution, Ecological Risk, and Source Identification of Heavy Metal(loid)s in Sediments of a Headwater of Beijiang River Affected by Mining in Southern China.

In this study, the contents of eight heavy metal(loid)s (As, Pb, Zn, Cd, Cr, Cu, Sb and Tl) in 50 sediment samples from a headwater of Beijiang River were studied to understand their pollution, ecological risk and potential sources. Evaluation indexes including sediment quality guidelines (SDGs), enrichment factor (EF), geo-accumulation index (), risk assessment code (RAC) and bioavailable metal index (BMI) were used to evaluate the heavy metal(loid)s pollution and ecological risk in the sediments. Pearson's correlation analysis and principal component analysis were used to identify the sources of heavy metal(loid)s.
