Departing from standard practices: Strategic application of value engineering in the anatomy laboratory to enhance formaldehyde extraction using high‐impact, low‐cost, and low‐maintenance solutions

open access: yesAnatomical Sciences Education, Volume 18, Issue 3, Page 241-253, March 2025.
Abstract This study describes the process of developing a high‐impact, low‐cost, and low‐maintenance air ventilation system for anatomy facilities. It employed the strategic application of Value Engineering (VE), assuring that the air ventilation system meets contemporary threshold limit values (TLVs) for formaldehyde in the working zone of dissection ...

Pss knockdown in the midgut causes growth retardation in Drosophila similar to that in human LMHD

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Phosphatidylserine synthase (PSS), localized in the mitochondrial membrane, synthesizes phosphatidylserine. In humans, mutations in Pss lead to Lenz–Majewski hyperostotic dwarfism, a disorder affecting growth and development. The effects of Pss mutations on the growth of Drosophila melanogaster are not fully known. Hence, this study

Capillary Zone Electrophoresis for the Analysis of Phenolic Preservatives in Plasma and Insulin Formulations Using Salting‐Out Assisted Liquid–Liquid Extraction

open access: yesELECTROPHORESIS, EarlyView.
A rapid and reliable SALLE–CZE–UV method was developed for the determination of phenolic preservatives in insulin formulations and human plasma. The approach provides efficient extraction, fast separation (< 6 min), and excellent sensitivity, precision, and recovery, meeting regulatory requirements for accurate quantification.

GC × GC‐TOF MS and Sensory Profiling of Aroma Compounds in Magnolia Species: Effects of Processing Methods on Volatile Retention in M. wufengensis

open access: yesFlavour and Fragrance Journal, EarlyView.
The first comparative analysis of Magnolia scents reveals that M. wufengensis is characterised by a high aldehyde content, exhibiting a fresh, sweet, and fruity fragrance profile. Furthermore, freeze‐drying preserves 6.7 times more 2‐nonenal compared to shade‐drying, highlighting its superior efficacy in retaining key volatile compounds.
