The straightforward identification of impurity signals in nuclear magnetic resonance (NMR) spectra is imperative for the structure elucidation and signal assignment synthetic products intermediates. To keep pace with emergence novel green solvents auxiliary compounds (e.g., acids bases), NMR tables databases must be regularly updated. This study reports residual 1H 13C chemical shifts 42 solven...

We construct new families of $\text{AdS}_2 \times S^2 S^2$ solutions with 4 supercharges in Type II supergravities. show that subclasses these can be interpreted terms defect branes embedded 4d $\mathcal{N} = $ SYM, or orbifolds thereof. This is explicitly realised by showing the asymptote locally to $\text{AdS}_5 S^5/\mathbb{Z}_n$, IIB, its T-dual background, IIA. The latter a Gaiotto-Maldacen...

Abstract Study question Is there an association between mitochondrial DNA (mtDNA) content and Ongoing Pregnancy Rate (OPR) in D5 or D6 euploid blastocyst? Summary answer Day6 OPR is decreased high mtDNA blastocyst. Day5 levels are independent of maternal age standard morphology. What known already Preimplantation development energy-demanding process ATP production crucial for cellular activity ...

We obtain a supergravity solution arising when D6-branes are wrapped on coassociative four-cycles of constant curvature in seven manifolds of G2 holonomy. The solutions preserve two supercharges and thus represent supergravity duals of three dimensional Yang-Mills with N = 1 supersymmetry. When uplifted to eleven dimensions our solution describes M-theory on the background of an eight manifold ...

PURPOSE the aim of our study was to assess the potential of combined intratendinous injection of an anti-angiogenic drug: bevacizumab (AA) and Platelet Rich Plasma (PRP) to treat tendinopathy in a murine model of patellar and Achilles tendinopathy, and to evaluate its local toxicity. MATERIAL AND METHOD twenty rats (80 patellar and Achilles tendons) were used for the study. We induced tendino...

Vangueria infausta burch subsp. infausta (Rubiaceae) produces fruits eaten by humans and animals. The leaf, fruit, stem bark and root bark are used as a remedy for many ailments and the roots are used to treat malaria. In this study, concentrations of fractions of the V. infausta root bark extract that produce 50% inhibition (IC50) are determined using the ability of the extract to inhibit the ...

The organosilicon compounds octamethylcyclotetrasiloxane (D4), decamethylcyclopentasiloxane (D5), and dodecamethylcyclohexasiloxane (D6) are high production volume chemicals that are widely used in household goods and personal care products. Due to their prevalence and chemical characteristics, cyclic siloxanes are being assessed as possible persistent organic pollutants. D4, D5, and D6 were me...

We discuss the lift of certain D6-antiD6-brane systems to M-theory. These are purely gravitational configurations with a bolt singularity. When reduced along a trivial circle, and for large bolt radius, the bolt is related to a nonsupersymmetric orbifold type of singularity where some closed string tachyons are expected in the twisted sectors. This is a kind of open-closed string duality that r...

We present our searches for the tubular bound states of a D2-brane with m D0-brane and n fundamental strings in the NS5-brane, Dp-brane or macroscopic strings backgrounds by solving the Dirac-Born-Infeld equation. The geometry of tubular configurations we considered are taken to be parallel to the background branes or macroscopic strings. The n fundamental strings therein may be the circular st...
