Induction and Enhancement of Bacteriocin Production (Review)

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Conventionally, bacteriocins are produced by microorganisms on complex substrates, released as semi‐purified preparations or crude fermentates. These bacteriocin‐containing products often exhibit unsatisfactory purity, low active‐substance content, and high production costs, limiting their commercialization and use. This review aims to analyze

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.

Conical Intersections in Thymine

, 2016
The mechanisms which are responsible for the radiationless deactivation of the nπ* and ππ* excited singlet states of thymine have been investigated with multireference ab initio methods (the complete-active-space self-consistent-field (CASSCF) method and

A Cytosine‑Bulged (3+1) Hybrid G‑Quadruplex Formed by the Chicken DNA Replication Origin

Chemistry – A European Journal, EarlyView.
The first high‐resolution structure of an OGRE‐derived G‐quadruplex from the chicken β‐globin replication origin reveals an intramolecular three‐layer (3+1) hybrid fold with a cytosine bulge and an unprecedented 5'‐outer‐quartet anti guanine, creating a distinctive surface for molecular recognition.

Multivalent RNA‐Cleaving Agents on a Cubic Octameric Silsesquioxane Core

Chemistry – A European Journal, EarlyView.
RNA‐cleaving agents on a cubic octameric silsesquioxane core were synthesized and characterized. Several catalytic systems of these structures were screened using hexaribonucleotide models. The best systems were then further used to study their catalytic efficiency in cleaving a HER2 mRNA model sequence. The induced cleavage sites were also determined.

Laser flash photolysis and magnetic-field-effect studies on interaction of thymine and thymidine with menadione: role of sugar in controlling reaction pattern

Science and Technology of Advanced Materials, 2008
The magnetic field effect (MFE) in conjunction with laser flash photolysis has been used for the study of the interaction of one of the small drug like quinone molecules, 2-methyl, 1,4-naphthoquinone, commonly known as menadione (MQ), with one of the DNA

Pulsed Light Technology in Food Safety and Preservation: Principles, Applications, and Future Directions

Food Chemistry International, EarlyView.
Pulsed light technology uses short high‐intensity broad‐spectrum flashes (200–1100 nm) to inactivate microbes via DNA damage. It preserves food quality, extends shelf life, and works on liquids, meats, and produce, often combined with other hurdles for enhanced efficacy.

Uso da 99mTc-Timina na identificação de metástases de tumor venéreo transmissível canino com apresentação cutânea The use of 99mTc-Thymine to identify metastatic disease in dogs presenting the cutaneous form of canine transmissible venereal tumor

Pesquisa Veterinária Brasileira, 2008
O tumor venéreo transmissível canino (TVTC) é descrito na literatura como raramente metastático. Entretanto, métodos acurados para verificação dessa afirmativa não estão disponíveis na rotina veterinária.
