Mycoplasma infections pose significant challenges in the poultry industry, necessitating effective therapeutic interventions. Tiamulin, a veterinary antibiotic, has demonstrated efficacy against species. However, emergence of resistant species could dramatically reduce potential, contributing to economic losses. Optimizing tiamulin’s pharmacokinetic profile via nanocarrier incorporation enhance its potential and administration frequency, ultimately reducing strain emergence. Niosomes, type self-assembled non-ionic surfactant-based nanocarrier, have emerged as promising drug delivery system, offering improved stability, sustained release, enhanced bioavailability. In this study, niosomal nanocarriers encapsulating tiamulin were prepared, characterized assessed Mycoplasma-inoculated broilers following oral administration. Differential scanning colorimetry (DSC) confirmed alterations crystalline state components integration into structures formed during formulation procedure. Transmission electron microscopy (TEM) showed spherical nanostructure niosomes. The formulated exhibited zeta average hydrodynamic diameter −10.65 ± 1.37 mV 339.67 30.88 nm, respectively. Assessment parameters gallisepticum-infected revealed ability increase bioavailability systemic exposure, marked by significantly higher area under curve (AUC) (p < 0.01) prolonged elimination half-life (T1/2) 0.05). Enhanced residence time are crucial factors maintaining concentrations at reduced doses frequencies. This approach provides viable strategy decrease risk subtherapeutic levels, thereby mitigating development antibiotic resistance. findings presented herein offer sustainable for efficient use antibiotics medicine.

Abstract Chemoresistance and severe toxicities represent major drawbacks of chemotherapy. Natural extracts, including the essential oils Pistacia lentiscus (PLEO), exhibit substantial anticancer anti-inflammatory activities where different cancers are reported to dramatically recess following targeting with PLEO. PLEO has promising antimicrobial, anticancer, properties. However, therapeutic properties restricted by limited stability, bioavailability, ability. nanoformulation can maximize their physicochemical properties, overcoming shortcomings. Hence, was extracted its chemical composition determined GC–MS. 5-Fluorouracil (5FU) were electrospun into poly-ε-caprolactone nanofibers (PCL-NFs), 290.71 nm 680.95 diameter, investigate potential synergistic against triple-negative breast cancer cells (MDA-MB-231), human adenocarcinoma (MCF-7), skin melanoma cell line (A375). The prepared (NFs) showed enhanced thermal stability remarkable physical integrity tensile strength. Biodegradability studies prolonged over 42 days, supporting NFs use as a localized therapy tissues (postmastectomy) or melanoma.

Cancer is a global health burden and one of the leading causes death. Photodynamic therapy (PDT) considered an alternative approach to conventional cancer treatment. PDT utilizes light-sensitive compound, photosensitizers (PSs), light irradiation, molecular oxygen (O2). This generates cytotoxic reactive species (ROS), which can trigger necrosis and/ or apoptosis, cell death in intended tissues. Classical impose limitations that hinder their clinical applications, such as long-term skin photosensitivity, hydrophobic nature, nonspecific targeting, toxic cumulative effects. Thus, nanotechnology emerged unorthodox solution for improving hydrophilicity targeting efficiency PSs. Among nanocarriers, mesoporous silica nanoparticles (MSNs) have gained increasing attention due high surface area, defined pore size structure, ease modification, stable aqueous dispersions, good biocompatibility, optical transparency, are vital PDT. The advancement integrated MSNs/PDT has led inspiring multimodal nanosystem effectively treating malignancies. review gives overview main components mechanisms process, effect on tumor cells, most recent studies reported benefits incorporating PSs into integration with against different cells.
