Monosaccharide‐Based Macrocyclic Receptors—History and Recent Applications

Helvetica Chimica Acta, EarlyView.
This perspective provides an overview of most common applications of monosaccharide‐based macrocycles in molecular recognition over the past four decades. The most recent achievements, such as fluorescent ion sensing and selective amino acid binding in aqueous media, including the work from the author's lab, are highlighted. Potential future directions

Ornithine enhances common bean growth and defense against white mold disease via interfering with SsOAH and diminishing the biosynthesis of oxalic acid in Sclerotinia sclerotiorum

Frontiers in Plant Science
The necrotrophic fungal phytopathogen, Sclerotinia sclerotiorum (Lib.) de Bary, employs a multilayered strategy to infect a wide range of host plants. The current study proposed the diamine L-ornithine, a non-proteinogenic amino acid that promotes the ...

Second‐trimester multimetabolite panel for early preeclampsia rule‐out

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective We aimed to establish a high‐sensitivity, multimetabolite rule‐out model for the development of preeclampsia (PE), prioritizing minimizing false negatives to exclude low‐risk individuals from intensive surveillance confidently. Methods In this prospective, nested case–control study, maternal serum samples were collected between 20+0 ...

Evaluating the Role of Analogies in Biochemistry Education: Lessons Learned From Pre‐ and Post‐Pandemic Dental Student Perceptions

Journal of Dental Education, EarlyView.
ABSTRACT Biochemistry forms the foundation for understanding biomolecules and molecular processes crucial to dental and oral biology. However, it is often perceived as a challenging subject for dental students with diverse educational backgrounds. Analogies are a pedagogical tool that helps explain new and abstract concepts in biochemistry.

Association between specialized nutrition support and 90‐day mortality relative to standard of care in malnourished adults with decompensated cirrhosis: A retrospective cohort study

Journal of Parenteral and Enteral Nutrition, EarlyView.
Abstract Background Malnutrition is common among patients with decompensated liver cirrhosis and linked to poor prognosis. Guidelines recommend intensified nutrition support e.g. parenteral nutrition, but evidence regarding safety and effectiveness is scarce. We aimed to investigate the impact of nutrition support, specifically parenteral nutrition, on

Salt‐induced nutritional and metabolic shifts in halophytes: implications for food security

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Plant species vary in their response to salinity: some crops show a degree of salt tolerance, while halophytes – whether wild or cultivated – are characterized by a high capacity to thrive under saline conditions. Halophytes are considered a source of valuable secondary metabolites with potential economic value, yet they might also produce ...

The ornithine cycle in Neurospora and its genetic control [PDF]

, 1944
It has been emphasized by Haldane (1) that for studies of intermediary metabolism "the new science of genetics furnishes a very powerful method." Such a method is founded upon the general premises that genes control many of the chemical reactions within ...

Main effects of ascorbic acid levels and organic acid type on physicochemical properties, microbial populations, texture, and biogenic amine formation in sucuk

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Sucuk is a traditional Turkish dry fermented sausage, the quality and safety of which depend on physicochemical, microbiological, and biochemical changes during fermentation and ripening. Organic acids, their salts, and antioxidants such as ascorbic acid (AA) are widely used in fermented meat products; however, information about ...

Current Insight into Human Ornithine Aminotransferase: A Review

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Human ornithine aminotransferase (hOAT) is a mitochondrial matrix pyridoxal‐5′‐phosphate enzyme (PLP) that catalyzes the reversible transfer of the δ‐amino group of L‐ornithine (L‐Orn) to α‐ketoglutarate (α‐KG) yielding glutamate‐5‐semialdehyde (GSA) and glutamate. GSA is prone to cyclize to Δ1‐pyrroline‐5‐carboxylate.
