Gold Nanoparticles

Turmeric has been reported to reduce brain volume in mice models, TB positive and intestinal inflammation in mice models. The purpose of the study was to develop and optimize the curcumin-loaded nanostructured lipid carriers (NLCs) by hot high-pressure homogenization method in order to increase its oral bioavailability. The optimized formulation displayed the following properties, a particle size of 165.9 nm, and high entrapment efficiency, strong zeta potential providing physical stability. Sustained release was observed in vitro and in vivo pharmacokinetic analysis showed strongly increased systemic exposure and extended circulation half-life with respect to free curcumin. The study findings validate the findings that NLCs offer a potential delivery vehicle to facilitate enhanced bioavailability of poorly bioavailable bioactives and that NLCs have prospects in pharmaceutical and nutraceutical fields.

Analytical method validation (AMV) in the veterinary field forms an important aspect of quality control in pharmaceutical companies in which drugs are used to treat various species of animals to guarantees safety, efficacy and regulatory actions are adhered to. This review points to the significance of the species-based approaches in pharmacokinetics of drug absorption, distribution, metabolism, and residue detection with a focus on the issues of physiological diversity, complex biological samples and ethical requirement. Modern methods such as HPLC, UPLC, GC, LC-MS/MS, UV-Vis, and FTIR are characterized by sensitivity, specificity, and reproducibility and newer techniques such as capillary electrophoresis and microfluidic-based technology, high-resolution mass spectrometry and bioinformatics-directed validation incorporates enhanced sensitivity, specificity, reproducibility, reduced sample volumes, and increased throughput. Future methodological advances in multi-dimensional platforms, green analytical chemistry, chemometrics, and machine learning offer new ways of addressing matrix effects and resource limitations and regulatory limitations. Taken together, these strategies can contribute to effective veterinary drug monitoring, food safety, and sustainable and species-specific AMV practices and direct future research at achieving harmonized and technologically more advanced validation processes.
