Non-specific effect of double-stranded RNAs on Egyptian broomrape (Phelipanche aegyptiaca) seed germination

open access: yesFrontiers in Plant Science
Obligate root parasitic plants of the Orobanchaceae family exhibit an intricate germination behavior. The host-dependent germination process of these parasites has prompted extensive research into effective control methods.

A machine learning-based strategy to elucidate the identification of antibiotic resistance in bacteria

open access: yesFrontiers in Antibiotics
Microorganisms, crucial for environmental equilibrium, could be destructive, resulting in detrimental pathophysiology to the human host. Moreover, with the emergence of antibiotic resistance (ABR), the microbial communities pose the century’s largest ...

ROLE OF PURINERGIC RECEPTORS IN IMMUNE RESPONSE

open access: yesЖурнал микробиологии, эпидемиологии и иммунобиологии, 2016
Purine receptors are located on immune and somatic cells of animal and human organisms. Summation of signals from purine and TOLL-like receptors takes place on the level of inflammasome formation and results in summation of the first and second signals ...

Single molecule DNA sequencing via transverse electronic transport using a graphene nanopore: A tight-binding approach

open access: yes, 2016
We report a tight-binding model study of two-terminal graphene nanopore based device, for sequential determination of DNA bases. Using Greens function approach we calculate conductance spectra, I-V response and also the changes in local density of states

Symmetry and Minimum Principle at the Basis of the Genetic Code

open access: yes, 2017
The importance of the notion of symmetry in physics is well established: could it also be the case for the genetic code? In this spirit, a model for the Genetic Code based on continuous symmetries and entitled the "Crystal Basis Model" has been proposed ...
