Engineering Stable Lentiviral Vector Producer Cells Improves LVV Production
Biotechnology and Bioengineering, EarlyView.ABSTRACT Stable lentiviral vector producer cell lines represent a promising platform for scalable and cost‐efficient vector manufacturing, yet their productivity is often limited by intrinsic host‐cell constraints. In this study, we aimed to identify cellular factors restricting LVV production in stable doxycycline‐inducible GPRTG producer cell lines ...

Absence of spermine in filamentous fungi [PDF]
Journal of Bacteriology, 1977 Polyamines were examined in several yeasts and filamentous fungi. Whereas putrescine, spermidine, and spermine were present in the yeasts, spermine was not detected in any of the filamentous fungi.

Food Safety and Health, EarlyView.This review elucidates the formation pathways and detection technologies for ethyl carbamate, biogenic amines, and higher alcohols in Huangjiu. It concludes that integrated control frameworks are essential to decouple safety risks from the metabolic processes responsible for flavor development.

Revisiting small‐molecule fluorescent probes in food freshness detection
Smart Molecules, EarlyView.Fluorescent probes serve as versatile tools for food freshness monitoring. This review summarizes recent advances in probes targeting biogenic amines, hydrogen sulfide, pH values, and other key spoilage markers, highlighting their design principles, sensing mechanisms, and practical applications in food quality monitoring. Abstract Food spoilage driven

The Chemical Record, EarlyView.Nickel foam—one material, two faces, and several versatile roles depending on electrolytic conditions. For more than 50 years, nickel foam electrodes have served in electrosynthesis as powerful and readily available electrode materials. Due to their inexpensive nature and easy handling, they have been widely employed.

Difluoromethylornithine rebalances aberrant polyamine ratios in Snyder–Robinson syndrome
EMBO Molecular Medicine, 2023 Snyder–Robinson syndrome (SRS) results from mutations in spermine synthase (SMS), which converts the polyamine spermidine into spermine. Affecting primarily males, common manifestations of SRS include intellectual disability, osteoporosis, hypotonia, and

The interaction of spermine and pentamines with DNA [PDF]
Biochemical Journal, 1987 We studied the effects of spermine, two naturally-occurring pentamines isolated from the thermophile Thermus thermophilus and one synthetic pentamine on the aggregation and ‘melting’ temperature of calf-thymus DNA and on the B-to-Z transition of poly(dG-me5dC). All pentamines caused aggregation of DNA at much lower concentrations than that of spermine.
