Seed longevity and cryobiotechnology in the orchid genus cattleya.

Background: Orchid seeds are reputed to be relatively short-lived, although comparative studies across a wide range of storage temperatures and moisture contents are few.

Objective: To explore how a wide range of temperature and moisture contents affects seed longevity in the orchid genus Cattleya.

Materials And Methods: Seeds of three Brazilian orchid species in the genus Cattleya (C.

A preliminary study of the concentration of metallic elements in the blood of patients with multiple sclerosis as measured by ICP-MS.

It is estimated that multiple sclerosis (MS) affects 35,000 Brazilians and 2.5 million individuals worldwide. Many studies have suggested a possible role of metallic elements in the etiology of MS, but their concentration in the blood of MS patients is nonetheless little investigated in Brazil.

Nutritional value and antioxidant compounds during the ripening and after domestic cooking of bananas and plantains.

Genotypes of bananas and plantains have been studied for biofortification purposes, mainly due to content of resistant starch (RS) and polyphenols. This study aims to identify banana and plantain genotypes with a high content of resistant starch, phenolic compounds and minerals, and to evaluate the impact of the ripening stage and domestic thermal processing to select superior genotypes with high levels of functional compounds. In this study, it was used bunches of bananas and plantain genotypes.
