Molecular mechanisms that initiate meiosis have been studied in fungi and mammals, but little is known about the mechanisms directing the meiosis transition in other organisms. To elucidate meiosis initiation in plants, we characterized and cloned the ameiotic1 (am1) gene, which affects the transition to meiosis and progression through the early stages of meiotic prophase in maize. We demonstra...

Indole-3-carbinol (I3C) is a plant compound derived from glucosinolates, found in cruciferous vegetables. Researchers have indicated that I3C shows great promise as a cancer preventative and hormone-balancing agent. HyperChem 7.5 software was used for quantum mechanical calculations. The geometry optimization was carried out using Ab Initio method. QSAR parameters were generated with semi empir...

The conformational stability of hexahydropyridobenzodioxin and related derivatives in both protonated and non-protonated forms have been investigated by means of ab initio molecular orbital methods as well as semi-empirical AM1 and PM3 methods. One of the cis conformers (cis2e) has been found to be most stable due to the formation of an intramolecular hydrogen bond, other conformers including t...

BACKGROUND Increased endocannabinoid tonus by dual-action fatty acid amide hydrolase (FAAH) and substrate selective cyclooxygenase (COX-2) inhibitors is a promising approach for pain-relief. One such compound with this profile is 2-(2-fluorobiphenyl-4-yl)-N-(3-methylpyridin-2-yl)propanamide (Flu-AM1). These activities are shown by Flu-AM1 racemate, but it is not known whether its two single ena...

The nucleotide sequence and deduced amino acid sequence of the cytochrome cL of Methylobacterium extorquens (Pseudomonas AM1; Methylobacterium AM1) shows that this cytochrome c is completely different, except for its haem-binding site, from all other cytochromes.

We have examined the performance of semiempirical quantum mechanical methods in solving the problem of accurately predicting protein-ligand binding energies and geometries. Firstly, AM1 and PM3 geometries and binding enthalpies between small molecules that simulate typical ligand-protein interactions were compared with high level quantum mechanical techniques that include electronic correlation...

We are presenting the results obtained by computing different toxicity indices for some of newest JWH synthetic cannabinoids, using (Q)SAR models, ADME(T) predictions, simulations NMR spectral techniques and other computational dedicated software packages forensic analytical tools. have examined main physical chemical properties evaluated behavioral neurotoxicity pharmacokinetic profile 16 amin...

Among cardiovascular diseases, acute myocardial infarction stands out as the leading threat to human life, especially for men in the developed countries, where the morbidity and mortality attributable to this and other cardiovascular diseases is known reasonably well (1-3). This knowledge has enabled researchers to study other epidemiologic aspects of ischemic heart diseaseincluding those relat...

The doping reaction of truncated boron nitride and carbon nanotubes with aluminium atom wastheoretically investigated. The AM1, PM3, and PM6 semiempirical methods have been used toevaluate the thermochemistry of doping reactions of single walled boron nitride nanotubes andcarbon nanotubes. The enthalpy changes, Gibbs free energy changes, and entropy changes of studieddoping reactions were evalu...
