Ferroptosis: The Demise of Cells Through Phospholipid Peroxidation

Advanced Science, EarlyView.
The relative abundance of peroxidation‐resistant monounsaturated fatty acids (MUFAs) vs. peroxidation‐sensitive polyunsaturated fatty acids (PUFAs) incorporated into phospholipid (PL) is a key determinant of ferroptosis sensitivity, as the peroxidation of PL PUFA acyl chains (PUFA‐PL) disrupts membrane integrity, causing ferroptotic cell death ...

Optimized Enzymatic Synthesis of Hesperidin Fatty Acid Esters in a Two-Phase System Containing Ionic Liquid

Molecules, 2011
Response surface methodology (RSM) based on a five-level, three-variable central composite design (CCD) was employed for modeling and optimizing the conversion yield of the enzymatic acylation of hesperidin with decanoic acid using immobilized Candida ...

Nuanced differences in adenylate cyclase toxin production, acylation, and secretion may contribute to the evolution of virulence in Bordetella species

mBio
Bordetella pertussis, which causes the acute human disease whooping cough, evolved from Bordetella bronchiseptica, which causes long-term, chronic infections in a broad range of mammals. Both B. pertussis and B.

Overview of Encapsulated Lysine and Methionine and Their Impacts on Transition Cow Performance and Health

Animal Research and One Health, EarlyView.
The transition period in dairy cows, spanning 3 weeks before and after calving, is a critical phase characterized by increased nutrient demands, reduced dry matter intake (DMI), and elevated risk of metabolic disorders such as negative nutrient balance (NNB), lipolysis, proteolysis, and oxidative stress.

Fasting and Refeeding Mediated Phospholipid Remodeling Plays an Important Role in Improving Meat Quality of Aged Laying Hens

Animal Research and One Health, EarlyView.
ABSTRACT This study explored fasting‐induced physiological remodeling effects on meat quality in aged laying hens. Fasting for 15 days (F15) significantly reduced abdominal fat, intermuscular fat width, subcutaneous fat thickness, and liver index versus pre‐fasting (F0) (p < 0.05), which recovered post‐refeeding.

Synthesis of an Enzyme‐Triggered Chitosan‐Based Drug Delivery System for Peri‐Implantitis Prevention

Chemistry – A European Journal, EarlyView.
ABSTRACT Dental implants have become a leading solution for tooth loss, yet bacterial infections remain a major complication. Antibacterial implant coatings are an important approach to reduce or prevent bacterial infections at the implant. Given the oral cavity's complex microbiome and the importance of some commensal bacteria, it is crucial to ...

Synthesis and Isolation of Bismuth Scorpionate Complexes: Toward Bond Activation via Bismuth‐Ligand Cooperation

Chemistry – A European Journal, EarlyView.
ABSTRACT Over the past twenty years, main group chemistry has significantly expanded its scope to include reactivities once considered the exclusive domain of transition metals. Among the emerging concepts, element‐ligand cooperation has proven to be a powerful strategy for enabling bond activation reactions but remains relatively unexplored for ...
