2. Biomass Accumulation, Photosynthetic Pigments, Osmotic Adjustments and Antioxidant Activities of Leymus chinensis in Response to BA, BR, and GA
RESUMO: Estresses abióticos e baixo acúmulo de biomassa são as principais restrições para se atingir o potencial de rendimento de Leymus chinensis. Foi conduzido um experimento para melhorar a biomassa e a correlação de atributos de acúmulo de biomassa com pigmentos fotossintéticos, substâncias osmóticas e antioxidantes sob aplicação foliar de d

3. Effects of Arbuscular Mycorrhiza on Osmotic Adjustment and Photosynthetic Physiology of Maize Seedlings in Black Soils Region of Northeast China
ABSTRACT To investigate the effect of arbuscular mycorrhiza fungi on maize growth, osmoregulation substances and photosynthetic physiology, a popular maize variety ZD 958 was measured under potted condition. Arbuscular mycorrhiza (AM) symbiosis promoted plant growth, and enhanced plant height, leaf length, mean leaf width and dry weight. Higher soluble sugar

4. Behavior of industrial strains of Saccharomyces front inhibitory compunds present in sugarcane molasses in the production of biothenol / Comportamento de linhagens industriais de Saccharomyces frente a compostos inibitorios presentes no melaço de cana-de-açucar na produção de bioetanol
The general objective of this project was the evaluation of the effects of some organic substances present in molasses, sugar cane on strains of yeast for industrial use. Chapter I refer to a brief introduction and history of alcoholic fermentation. In Chapter II, samples of industrial molasses were examined, from 10 units producing sugar, located in the sta

5. Efeitos de um extrato aquoso de buzhong yi qi wan (fórmula magistral chinesa) na marcação de constituintes sanguíneos com tecnécio-99m, na morfologia e na fragilidade osmótica de hemácias de ratos Wistar
Technetium-99m (99mTc) has been used to obtain several radiobiocomplexes utilized to aid in the diagnosis of diseases. Blood constituents, as red blood cells (RBC) and plasma proteins, have been labeled with 99mTc. Natural and synthetic drugs can alter the labeling of these constituents. The aim of this work was to investigate the possibility of a Bu

6. Influência da preparação do licor de jabuticaba (Myrciaria jaboticaba Vell berg) no teor de compostos fenólicos
Epidemologist researches suggest that an association with the consumption of foods and drinks with a great concentration of phenolic compounds and the prevention of some diseases is possible. The medicinal aspect of these compounds is due to their antioxidant substances. The jabuticaba ( Myrciaria jaboticaba Vell berg) a native Brazilian fruit has a great co

7. CARACTERIZAÇÃO MOLECULAR E BIOQUÍMICA DE CEPAS DE Saccharomyces cerevisiae UTILIZADAS NA CARACTERIZAÇÃO MOLECULAR E BIOQUÍMICA
Aiming the molecular characterization of Saccharomyces cerevisiae LBCM 427 strain, selected from fermentations vats of a cachaça distillery, several analysis using polymorphism analysis of DNA for the characterization/discrimination of this and the selvagem strains present in the origin place was used. Results showed that RAPD-PCR, mtDNA, and PCR using comp

9. Effect of Water on the Ripening of Pericarp Disks from Tomato Fruits 1
Color change, a measure of the ripening of pericarp disks of tomato fruits (Lycopersicon esculentum Mill. cv. Moneymaker), was delayed by osmotic water uptake. An even greater delay occurred when substances from the disks were allowed to leach out or to diffuse into agar, indicating the existence of a water-soluble substance(s) necessary for the ripening pro

10. The Na/K pump, Cl ion, and osmotic stabilization of cells
An equation for membrane voltage is derived that takes into account the electrogenicity of the Na/K pump and is valid dynamically, as well as in the steady state. This equation is incorporated into a model for the osmotic stabilization of cells. The results emphasize the role of the pump and membrane voltage in lowering internal Cl− concentration, thus mak

11. A Magnetic Suspension Osmometer
The magnetic suspension balance is used for the measurement of very small osmotic pressures. The apparatus is essentially the same as that previously used for the measurement of the density and viscosity of protein solutions except that the magnetically suspended buoy is modified to make it pressure sensitive. The method is especially useful for the measurem

12. Osmotic regulation of L-proline transport in Salmonella typhimurium.
The transport of proline is important for the adaptation of Salmonella typhimurium to osmotic stress because exogenous proline permits the growth of the organism in media of elevated osmotic strength that would otherwise be toxic. Measurements of the rate of [3H]proline transport in S. typhimurium indicated that the organism has two distinct proline permease
