VALIDATION OF SPECTROPHOTOMETRIC METHOD TO QUANTIFY QUERCETIN IN THE IN VITRO DISSOLUTION STUDY OF SELF NANO-EMULSIFYING DRUG DELIVERY SYSTEM (SNEDDS)

Jurnal Farmasi Sains dan Praktis, 2022
Quercetin possesses low solubility and decreases oral bioavailability. One way to increase the bioavailability of quercetin is by formulating a self-nanoemulsifying drug delivery system (SNEDDS).

Improving detection limit of non-dispersive infrared gas sensor with high precision by matched filtering

International Journal of Optomechatronics
Non-dispersive infrared (NDIR) gas sensors have the disadvantage of high limit of detection (LOD), and the signal-to-noise ratio (SNR) has a significant impact on LOD.

Longitudinal circulating tumor DNA profiling in patients with advanced endometrial cancer using an off‐the‐shelf targeted NGS panel

Molecular Oncology, EarlyView.
Intratumour heterogeneity complicates precision management of advanced endometrial cancer. Circulating tumor DNA (ctDNA) offers a minimally invasive strategy to capture tumor evolution and therapeutic resistance. Here, we compare tumor‐agnostic NGS with tumor‐informed ddPCR, outlining their relative sensitivity, concordance, and clinical implications ...

Double Competitive Immunodetection of Small Analyte: Realization for Highly Sensitive Lateral Flow Immunoassay of Chloramphenicol

Biosensors, 2022
A new scheme of reagents interaction for lateral flow immunoassay (LFIA) is proposed, which combines the features of competitive and sandwich assay and provides highly sensitive detection of low-molecular-weight analytes.

Dual-pulse laser induced breakdown spectroscopy in the vacuum ultraviolet with ambient gas: spectroscopic analysis and optimization of limit of detection of carbon and sulfur in steel [PDF]

, 2012
Laser Induced Breakdown Spectroscopy (LIBS) in the vacuum ultraviolet (VUV) spectral region was applied to standard steel samples in dual-pulse excitation mode with an ambient gas. Two lasers were employed in collinear geometry, one as an ablation laser (

Limit of detection values in data analysis: Do they matter? [PDF]

, 2011
Data sets containing values below the limit of detection (LOD) are known as ‘censored data sets’. Such data sets are encountered regularly in most fields of environmental contaminant research.

Clinical performance of the urine‐based TERT promoter AbsoluteQ Digital PCR for non‐invasive detection of bladder cancer

Molecular Oncology, EarlyView.
A urine‐based digital PCR assay targeting two hotspot TERT promoter variants detected bladder cancer with high sensitivity and no false positives in this case–control cohort. The streamlined AbsoluteQ workflow outperformed Sanger sequencing and supports non‐invasive molecular testing for bladder cancer detection.
