Simple RP-HPLC method for Aceclofenac quantitative analysis in pharmaceutical tablets [PDF]

Pharmacia, 2020
A reverse phase liquid chromatographic method for estimation of Aceclofenac in bulk drug and tablet dosage form was developed and validated. The chromatographic conditions to achieve the highest performance parameters using octylsilyl column with guard filter were optimized. The separation was carried out using a mobile phase containing 10 mM Phosphate

Quantification of DNA Products Using Ion-Pair Reverse Phase Liquid Chromatography [PDF]

, 2017
The transcription of DNA via RNA polymerases is a fundamental process in cellular systems. In eukaryotic cells, we observe transcription in the nucleus (via genomic DNA) as well as in the mitochondria (via mitochondrial DNA).

Systemic dysregulation of apolipoproteins in amyotrophic lateral sclerosis serum

FEBS Open Bio, EarlyView.
Amyotrophic lateral sclerosis (ALS) is a fatal disease that damages motor neurons. This study found that people with ALS show significant changes in blood fats and the proteins that carry them. Several apolipoproteins were higher, lipid balances were altered, and normal protein–lipid relationships were disrupted.

BNB/NBN‐Phenalenyl‐2'‐deoxyuridines as a Fluorophore–Quencher Pair in DNA

Angewandte Chemie, EarlyView.
Two BN‐chromophore‐extended nucleosides containing electronically complementary BNB‐ and NBN‐doped phenalenyls were synthesised and incorporated into deoxyribonucleic acid (DNA) oligonucleotides. These chromophores act as an efficient fluorophore–quencher pair under aqueous conditions.
