1. Simultaneous dehydration and infiltration with (2-hydroxyethyl)-methacrylate (HEMA) for lipid preservation in plant tissues
Although this study aims to develop an improved method for the preservation of reserve lipids in plant tissues for different uses in plant anatomy, it mostly aims to develop an improved method for the identification of lipid reserves where synthesis or storage occurs. The proposed procedures entail only the utilization of (2-hydroxyethyl)-methacrylate (HEMA)

2. Comparative proteomical analysis of zygotic embryo and endosperm from coffea arabica seeds.
During coffee seed development, proteins are predominantly deposited in cotyledons and in the endosperm. Reserve proteins of the 11S family are the most abundant globulins in coffee seeds, acting as a nitrogen source during roasting and guaranteeing flavor and aroma. The aim of the present study was to compare the protein profiles of endosperm and zygotic em

4. Variação sazonal de amido em tecidos de reserva do cafeeiro arábica na fase reprodutiva / Seasonal variation of starch in reserve tissues of arabica coffee in the reproductive stage
O café é a mais importante mercadoria no comércio agrícola internacional, representando uma significante fonte de renda para diversos países, incluindo o Brasil. A formação de gemas florais é um importante processo fisiológico em plantas superiores e o período de florescimento é influenciado pelas condições ambientais. Em Coffea arabica L. estud

5. Conexão entre os processos de degradação das reservas de proteinas e carboidratos e o edfeito dos hormonios e açucares em sementes de Sesbania virgata (Cav.) Pers / Connection between storage proteins and carbohydrates degradation and the effects of hormones and sugars in seeds of Sesbania virgata (Cav.) Pers
Seeds of Sesbania virgata (Cav.) Pers. have an endosperm which accumulates galactomannan as a storage polysaccharide in the cell walls that is hydrolysed after germination by three enzymes (a-galactosidase, endo-ß-mannanase and exo-ß-mannosidase). Besides the storage of carbon, there is a great amount of protein bodies in the cytoplasm of endospermic cells

6. Biology of Attenuated Modified Vaccinia Virus Ankara Recombinant Vector in Mice: Virus Fate and Activation of B- and T-Cell Immune Responses in Comparison with the Western Reserve Strain and Advantages as a Vaccine
The modified vaccinia virus Ankara (MVA) strain is a candidate vector for vaccination against pathogens and tumors, due to safety concerns and the proven ability of recombinants based on this vector to trigger protection against pathogens in animals. In this study we addressed the fate of the MVA vector in BALB/c mice after intraperitoneal inoculation in com

7. Constitutive telomerase expression promotes mammary carcinomas in aging mice
Telomerase is up-regulated in the vast majority of human cancers and serves to halt the progressive telomere shortening that ultimately blocks would-be cancer cells from achieving a full malignant phenotype. In contrast to humans, the laboratory mouse possesses long telomeres and, even in early generation telomerase-deficient mice, the level of telomere rese

8. An Antibody to the Castor Bean Glyoxysomal Lipase (62 kD) also Binds to a 62 kD Protein in Extracts from Many Young Oilseed Plants 1
An antibody raised against purified glyoxysomal lipase (triacylglycerol hydrolase EC 3.1.1.3.) from castor bean (relative molecular weight of 62,000) also binds to a protein with a relative molecular weight of 62,000 in extracts of food reserve tissues from many young oilseed plants. These plants include Brassica napus L., Zea mays L., Arachis hypogaea L., G

9. Enzymic Mechanism of Starch Breakdown in Germinating Rice Seeds II. Scutellum as the Site of Sucrose Synthesis1
In a close parallel to the developmental pattern of α-amylase activity, a rapid increase of maltase activity occurred in the endosperm tissue of germinating rice seeds after about 4 days of the seed imbibition. The overall pattern of the 2 hydrolytic enzyme activities strongly suggest that amylolytic breakdown is the major metabolic route of starch utilizat

10. Influence of Cotyledons upon α-Amylase Activity in Pea Embryonic Axes
α-Amylase activity remained relatively low in the axes of intact etiolated pea seedlings; the activity was predominantly confined to the epicotyl. Starch accumulated slightly. When the cotyledons were removed and the axes cultured on medium containing no carbon source, the starch reserve in the axes disappeared within a few days. This was accompanied by a 1

11. Abnormal Cardiac Development in the Absence of Heart Glycogen
Glycogen serves as a repository of glucose in many mammalian tissues. Mice lacking this glucose reserve in muscle, heart, and several other tissues were generated by disruption of the GYS1 gene, which encodes an isoform of glycogen synthase. Crossing mice heterozygous for the GYS1 disruption resulted in a significant underrepresentation of GYS1-null mice in

12. Nitrogen Reserve Mobilization during Regrowth of Medicago sativa L. (Relationships between Availability and Regrowth Yield).
An experiment was designed to study the role of N and C reserves on regrowth of the shoots following defoliation of forage species. Starch and N accumulation in root and crown tissue of nonnodulated Medicago sativa L. were modified during regrowth by applying different levels of N and different cutting heights. Plants were obtained with similar crown and roo
