The radio millisecond pulsar PSR B1620−26 is part of an extraordinary triple star system in the globular cluster M4. The inner companion to the neutron star is thought to be a white dwarf of mass m1 ≃ 0.3M⊙ in an orbit of period ≃ 0.5 yr. The nature and orbital characteristics of the second, more distant companion, have remained a mystery for many years. A theoretical analysis of the latest ava...

The lateral packing of a collagen-like molecule, CHJO(Gly-L-Pro-L-Pro),NHCH,, has been examined by energy minimization with the ECEPPN force jield. Two current packing models, the Smith collagen microjibril twisted equilateral pentagonal model and the quasi-hexagonal packing model, have been extensively investigated. In treating the Smith microjibril model, energy minimization was carried out o...

The sequence-specific recognition of double-helical DNA by oligodeoxyribonucleotide-directed triple-helix formation is limited mostly to purine tracts. Within the geometric constraints of the phosphate-deoxyribose position of a purine-purine-pyrimidine triple-helical structure, model building studies suggested that the deoxyribonucleoside 2'-deoxynebularine (dN) might form one specific hydrogen...

Few interventions for Postnatal Depression (PND) have focused on parenting difficulties; the aim of this research was to investigate the feasibility and evaluate a parenting intervention (Baby Triple P) in women with PND. This was a pilot randomised controlled trial (RCT) to evaluate and determine the feasibility of the newly developed Baby Triple P compared with treatment as usual (TAU) in wom...

Abstract The chemical processes occurring during the interaction of carbon (diamond) with silicon are experimentally investigated. Thermal analysis diamond is carried out. This made it possible to determine mechanism synthesis carbide and subsequent reaction sintering particles based on Turing’s reaction-diffusion process formation a microstructure consisting triple periodic surfaces minimal en...

The helical junction region of a -1 frameshift stimulating hairpin-type mRNA pseudoknot from sugarcane yellow leaf virus (ScYLV) is characterized by a novel C27.(G7-C14) loop 2-stem 1 minor groove base triple, which is stacked on a C8+.(G12-C28) loop 1-stem 2 major groove base triple. Substitution of C27 with adenosine reduces frameshifting efficiency to a level just twofold above the slip-site...

We report the radio continuum structure of the barred galaxy NGC 3367 with an angular resolution of ∼ 4 ′′ .5. The radio structure indicates emission from the disk and from a triple source consisting of the nucleus straddled by two extended sources (the lobes). The triple source shows an excess of radio continuum emission compared to the emission expected from the total radio-Hα correlation, su...

The presence of a suitable substrate(s) in soil may release physiologically active concentration of a plant hormone ethylene (C2H4) as a result of microbial activity. We isolated three strains of fungi (Aspergillus clavatus, Penicillium commure and Thamridium elegans), from the maize rhizosphere soil, capable of producing C2H4 in the soil from L-methionine (10 mmol l). The plate and soil inocul...

Summary: Long (>200bps) non-coding RNAs (lncRNA) can act as a scaffold promoting the interaction of several proteins, RNA and DNA. Some lncRNAs interact with the DNA via a triple helix formation. Triple helices are formed by a single stranded RNA/DNA molecule, which binds to the major groove of a double helix following a canonical code. Recently, sequence analysis methods have been proposed to ...
