Abstract:
... 24-Epibrassinolide (EBL) is considered the most probable brassinosteroid (BR) candidate that could be used for practical application in agriculture. EBL-induced stress-protective properties were evaluated in in vitro-grown tomato (Solanum lycopersicum L.) varieties Pusa Ruby (susceptible to nematodes) and PNR-7 (resistant to nematodes) during nematode pathogenesis. Sterilized tomato seeds treated ...

Abstract:
... Novel multimetallic copper pyrazolate complexes, inaccessible using simple pyrazole ligands due to competing, alternative structural motifs, can be obtained by locking pairs of pyrazole ligands together with ethylene tethers. Nanojars based on this tethered pyrazole ligand display unexpected total selectivity for the carbonate over the sulfate ion. ...

However, effective measures for preventing such abnormalities have not been developed for this species. Silver nitrate (AgNO₃) has been shown to revert hyperhydric plantlets to a normal state. Nevertheless, the effec ...

Abstract:
... Allyl borates, a new class of monofunctional polyhomologation initiators, are reported. These monofunctional initiators are less sensitive and more effective towards polymethylene-based architectures. As an example, the synthesis of α-vinyl-ω-hydroxypolymethylenes is given. By designing/synthesizing different allylic borate initiators, and using ¹H and ¹¹B NMR spectroscopy, the initiation mechanis ...

Abstract:
... Тhe DNA testing of autosomal recessive deafness type 1A (DFNB1A, MIM 220290) is complicated when deaf patients have only monoallelic (heterozygous) recessive mutations in the GJB2 (Сх26) gene that is uninformative for establishment of diagnosis. Such patients may be “random” heterozygous carriers of GJB2 mutations as well as have the mutant allele in a cis-regulatory region of GJB2 gene, in elemen ...

Abstract:
... Recent articles have provided estimates of evaporative flux from water tables in deserts that span 5 orders of magnitude. In this paper, we present an analytical calculation that indicates aquifer vapor flux to be limited to 0.01 mm/yr for sites where there is negligible recharge and the water table is well over 20 m below the surface. This value arises from the geothermal gradient, and therefore, ...
