2. Stress conditions in the host induce persister cells and influence biofilm formation by Staphylococcus epidermidis RP62A
Abstract INTRODUCTION: Studies have demonstrated that pathogens react to the harsh conditions in human tissues by inducing mechanisms that promote survival. METHODS: Persistence and biofilm-forming ability were evaluated during stress conditions that mimic those in the host. RESULTS: Carbon-source availability had a positive effect on Staphylococcus epide

3. Adubação com potássio e cálcio na nutrição e produção de goiabeira 'Paluma'
RESUMO A goiabeira é uma frutífera cultivada mundialmente, destacando-se pela grande aceitação no mercado consumidor. Entretanto, para que a cultura explore o seu máximo potencial produtivo e mantenha a qualidade dos frutos, é necessária a adequada adubação mineral para elevar a disponibilidade de nutrientes no solo e aumentar sua absorção pelas p

4. A Multi-Pumping Flow System with Pulsed Fluidization to Evaluate Soil Capacity for Phosphate Adsorption
Soils with high levels of iron and aluminum, thus negatively the phosphorous availability, affecting crop yields. A prior determination of the soil capacity to adsorb phosphate is relevant to attaining good agricultural performance. To this end, a multi-pumping flow system with pulsed fluidization is proposed. The procedure takes into account the amount of r

5. Iron deficiency in cancer patients
ABSTRACT Anemia is a frequent complication in cancer patients, both at diagnosis and during treatment, with a multifactorial etiology in most cases. Iron deficiency is among the most common causes of anemia in this setting and can develop in nearly half of patients with solid tumors and hematologic malignancies. Surprisingly, this fact is usually neglected b

6. Iron Availability in Tropical Soils and Iron Uptake by Plants
ABSTRACT Given the increase in crop yields and the expansion of agriculture in low fertility soils, deficiency of micronutrients, such as iron, in plants grown in tropical soils has been observed. The aim of this study was to evaluate Fe availability and Fe uptake by corn (Zea mays L.) plants in 13 different soils, at two depths. Iron was extracted by Mehlic

7. Evaluation of the technological, nutritional and sensory qualities of bakery products produced with partial substitution of the wheat flour by whole rice flour
Summary The objective of this work was to determine the technological, nutritional and sensory characteristics of bread produced by substituting 25 and 50% of conventional wheat flour by whole rice flour (Oryza sativa L). The final products were evaluated in terms of specific loaf volume, appearance of the central slice, crumb firmness, moisture content, die

8. Oxidative damage and photosynthetic impairment in tropical rice cultivars upon exposure to excess iron
ABSTRACT Iron plays a pivotal role in the redox reactions of photosynthesis and metabolic processes such as chlorophyll synthesis. Iron availability in waterlogged soils can reach toxic levels and promote oxidative stress. Fe toxicity is the most concerning of stresses for rice in many lowland environments around the world and may cause severe impairments in

9. Modulatory effect of iron chelators on adenosine deaminase activity and gene expression in Trichomonas vaginalis
Trichomonas vaginalis is a flagellate protozoan that parasitises the urogenital human tract and causes trichomoniasis. During the infection, the acquisition of nutrients, such as iron and purine and pyrimidine nucleosides, is essential for the survival of the parasite. The enzymes for purinergic signalling, including adenosine deaminase (ADA), which degrades

10. Nutritional characteristics of biofortified common beans
Iron and zinc deficiency can cause anemia and alterations in the immune response and impair work capacity. To minimize this problem, biofortification has been developed to improve and/or maintain the nutritional status of the population. Beans are an important source of carbohydrates, proteins, and minerals. The objective of this study is to characterize bio

11. Estado nutricional e disponibilidade de nutrientes e carotenóides para a população brasileira / Nutritional status and availability of nutrients and carotenoids for the Brazilian population
The study aimed to analyze the household availability of energy, nutrients and carotenoids to Brazilian families living in rural and urban areas, the Major Geographic Regions, as well as the nutritional status of adults belonging to this population. The individual information from the Household Budget Survey (POF 2008-2009) from the Brazilian Institute of Ge

12. Increased hepcidin expression in multibacillary leprosy
Iron is essential for all organisms and its availability can control the growth of microorganisms; therefore, we examined the role of iron metabolism in multibacillary (MB) leprosy, focusing on the involvement of hepcidin. Erythrograms, iron metabolism parameters, pro-inflammatory cytokines and urinary hepcidin levels were evaluated in patients with MB and m
