The objective of this systematic review and meta-analysis was elucidating the association of VDR SNPs (FokI, TaqI, BsmI, BgII, and ApaI) with neonatal sepsis. Literature search was performed to retrieve records published until August 2nd, 2023 (PROSPERO registration: CRD42023451355). Meta-analysis was carried out to determine the pooled estimates for Odds Ratio (OR).

This study introduces a novel and simple way to suppress the self-absorption effect in laser-induced breakdown spectroscopy (LIBS) by utilizing a defocusing laser irradiation technique. For this purpose, a Nd:YAG laser with a wavelength of 1,064 nm and repetition rate of 10 Hz with energy in the range of 10 mJ-50 mJ was used. The laser irradiation was focused by using a 150-mm-focal-length plano-convex lens onto the sample surface under defocusing of approximately -6 mm.

Article Synopsis
  • * Traditional detection methods like gas chromatography are offline and damaging to the samples; this study introduces a new technique using laser-induced breakdown spectroscopy (LIBS) for real-time detection.
  • * The novel method, which incorporates metastable helium, achieves high-quality emission spectra with an impressive detection limit of 0.51 mg/kg for hydrogen, allowing for efficient analysis even at low concentrations.
