Article
‘Sugars Will Eventually be Exported Transporters’ (SWEETs) are a group of sugar transporters that play crucial roles in various biological processes, particularly plant stress responses. However, no information is available yet for the CaSWEET family in chickpea. Here, we identified all putative CaSWEET members in chickpea, and obtained their major...

Bacterial blight is one of the most devastating rice diseases that cause huge economic loss worldwide. The cause of rice blight is Gram negative bacteria Xanthomonas oryzae pv. oryzae (X. oryzae pv. Oryzae). Since both silver nanoparticles and chitosan have antibacterial, antifungal and growth-stimulating effect, this work has focused on synthesizi...

Nảy mầm sớm trên cây (Pre-harvest sprouting - PHS) là một trong những yếu tố gây tác động xấu đến năng suất và chất lượng ngũ cốc trên toàn thế giới. Bản chất của hiện tượng này là do sự thay đổi về nồng độ hormone abscisic acid (ABA) và gibberellic acid (GA) trong phôi, từ đó hạt nảy mầm ngay trên cây mẹ. Các chiến lược chọn giống trên thế giới hi...

A disposable card incorporating specific DNA probes targeting the 16 S rRNA gene of Streptococcus suis was developed for magnetically labeled target DNA detection. A single-stranded target DNA was hybridized with the DNA probe on the SPA/APTES/PDMS/Si as-prepared card, which was subsequently magnetically labeled with superparamagnetic beads for det...

Wheatstone bridges incorporating a serially connected ensemble of simple AMR elements of Ni80Fe20 film were produced, targeting an application of a pinned magnetic field along the sensing magnetoresistor length. For the optimal dimension, the magnetoresistive element with length l = 4 mm, width w = 150 μm and thickness t = 5 nm still shows a rather...

This review focuses on methods of designing photocontrolled proteins and nucleic acids. Data on preparation and modification of proteins and nucleic acids with azobenzene derivatives are summarized. Examples of using photoswitchable proteins, their substrates, inhibitors and ligands containing azobenzene, as well as azobenzene derivatives of nuclei...
Conference Paper
With the aim to use a "flat film-like shape" excitation source in the opto-biomedical analysis system (OBMAS), a deep-blue organic light emitting diodes (OLED) with 240 mm2 in size and an emission wavelength of 455 nm were fabricated by vacuum evaporation of low-molecular-weight polymers. In the devices N, N-Bis(naphthalen-1-yl)-. N, N-bis(phenyl)...
Article
A novel method for regulating the activity of homodimeric proteins--"molecular gate" approach--was proposed and its usefulness illustrated for the type II restriction endonuclease SsoII (R.SsoII) as a model. The "molecular gate" approach is based on the modification of R.SsoII with azobenzene derivatives, which allows regulating DNA binding and cle...

For many applications it would be desirable to be able to control the activity of proteins by using an external signal. In the present study, we have explored the possibility of modulating the activity of a restriction enzyme with light. By cross-linking two suitably located cysteine residues with a bifunctional azobenzene derivative, which can ado...

Derivatives of azobenzene which contained a maleimide group in one of the benzene rings (for binding to a protein cysteine residue) and maleimide, hydroxyl, or carboxyl substitutes in another benzene ring were synthesized. The reactivity of these compounds towards a cysteine residue of a protein and their optical properties in a free form and after...

The adsorption of a basic dye (Methylene Blue; MB) and an acidic dye (Acid Orange; AO) has been studied on three activated carbons (ACs; FAS, SKD, and BAU) significantly differing in their porous structures and surface concentrations of ion-exchange groups and on graphitic thermal carbon black (GTCB). The effective specific surface area of FAS, SKD...
