Cryopreservation of seeds of Neonotonia wightii Wight and Arn: a strategy for conservation, dormancy breaking and preservation of nutritional status.

Background: N. wightii (Leguminosae) is valued as a cover crop and as a potential source of protein in food insecure countries. However, plantlet establishment is limited by physical dormancy.

Ce/Pumice and Ni/Pumice as heterogeneous catalysts for syngas production from biomass gasification.

This work presents a study of synthesis and characterization of catalysts-based cerium and nickel supported on the pumice stone (Ce/Pumice and Ni/Pumice) to be used in the gasification process of an invasive species present in the Canary Islands, such as Pennisetum setaceum to obtain syngas. Specifically, the effect of the metal impregnated on the pumice, and the effect of catalyst on the gasification process was studied. For this purpose, the composition of the gas was determined and the results obtained were compared with those obtained in non-catalytic thermochemical processes.

Parameterization and Application of the General Amber Force Field to Model Fluoro Substituted Furanose Moieties and Nucleosides.

Molecular mechanics force field calculations have historically shown significant limitations in modeling the energetic and conformational interconversions of highly substituted furanose rings. This is primarily due to the gauche effect that is not easily captured using pairwise energy potentials. In this study, we present a refinement to the set of torsional parameters in the General Amber Force Field () used to calculate the potential energy of , , and -fluorinated nucleosides.

Workup and Management of Thyroid Nodules.

Thyroid nodules are extremely common findings with a low likelihood of harboring a clinically significant malignancy. Ultrasound is highly sensitive at identifying which nodules warrant further workup with fine needle aspiration (FNA) biopsy. FNA should be performed based on US findings and risk categories.

Exposure of Teramnus labialis (L.F.) Spreng Seeds to Liquid Nitrogen Does Not Affect Nutritional Status of Field Grown Adult Plants.

Background: Teramnus labialis (L.f.) Spreng is a potentially important legume species, and can be used as an animal feed and to enhance soil physicochemical characteristics.
