Chemical Syntheses of 3′ and 5′ Phosphorylated Oligonucleotides: An Overview

European Journal of Organic Chemistry, EarlyView.
This review provides an overview of the various chemical methods employed in the synthesis of oligonucleotides bearing a phosphate group at their 3′ or 5′ end. Notably, it presents modified phosphoramidites and supports developed for this purpose. Oligonucleotides (ON) with a phosphate monoester group at their 3′ or 5′ end have applications in many ...

Nonthermal Food Processing Technologies: A Comprehensive Review

Future Postharvest and Food, EarlyView.
The graphical abstract illustrates the shift from traditional thermal food preservation methods to advanced nonthermal technologies. Traditional methods, represented by heating, often compromise the nutritional and sensory quality of foods. In contrast, nonthermal approaches such as high‐pressure processing (HPP), pulsed electric field (PEF ...

Isolation of acetylcholinesterase gene from Egyptian Anopheles pharoensis (Theobald)

Journal of Basic and Applied Zoology, 2012
Acetylcholinesterase (ACE) is the target of two major insecticide families, organophosphates (OPS) and carbamates. Acetylcholinesterase is a frequent resistance mechanism in insects and responsible mutations were identified in many dipteran species.

Thymine Incorporation and Metabolism by Various Classes of Thymine-less Bacteria [PDF]

Journal of General Microbiology, 1965
SUMMARY: Escherichia coli strain 15T- yielded 109 organisms from 1 μg. thymine and growth was continuous, not diphasic. Aminopterin-selected thymine-less bacteria, on the other hand, required 20-25 μg. thymine/ml. to sustain growth, although thymine incorporation was the same as for strain 15T-, approximately 10-9 μg./bacterium.

Joining Nanotubes Comprising Nucleobase-carrying Amphiphilic Polypeptides

CHIMIA, 2018
Three kinds of amphiphilic polypeptides, X-poly(sarcosine)-b-(L-Leu-Aib)6 (X = adenine, thymine, glycolic acid), were synthesized and self-assembled in a tris buffer to take on nanotube morphology.

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 ...

Interactions of some metal ions with Nitrogenous bases present in Nucleotides

مجلة بغداد للعلوم, 2007
Acidity constants at 30co and 0.125 ionic strength have been determined for the Nitrogous bases of nucleic acid; cytocine, uarcil and thymine, and found to be 3.55 x10-19 , 1.44 x10 -19 and 7.24 x10 -20 respectively.
