honey contains a wide variety of vitamins, minerals, amino acids and antioxidants. the vitamins found in honey include niacin, riboflavin and pantothenic acid; minerals present include calcium, copper, iron, magnesium, manganese, phosphorus, potassium and zinc. in addition honey contains a variety of flavonoids and phenolic acids which act as antioxidants, scavenging and eliminating free radica...

The role of the minerals in epidermal methylcholanthrene carcinogenesis in mice has been described (1), and the integration of the chemical, physical, and histological changes has been reviewed recently by Cowdry (3). The present study was undertaken to compare the calcium, copper, and zinc content of mouse and human epidermis with that in squamous cell carcinomas from mouse and man respectivel...

Skeletal biomineralisation by microbial eukaryotes significantly affects the global biogeochemical cycles of carbon, silicon and calcium. Non-skeletal biomineralisation by eukaryotic cells, with precipitates retained within the cell interior, can duplicate some of the functions of skeletal minerals, e.g. increased cell density, but not the mechanical and antibiophage functions of extracellular ...

Proximate (live mass, water, lipid, ash, non-fat organic), caloric, nitrogen, and mineral (sodium, potassium, calcium, magnesium, and iron) concentrations and total body content of individuals of 24 species of Neotropical and Paleotropical bats were determined. Mass-related, concentration patterns were found for all measured variables, except iron. Concentrations increase with size for nitrogen...

The formation of intricately shaped crystalline minerals by organisms is orchestrated by specialized biomacromolecules. The macromolecules associated with coccoliths, nanometer-sized calcite crystal arrays produced by marine microalgae, can form a distinct calcium-rich phase via macromolecular recognition. Here, we show that this calcium-rich phase can be mineralized into a thin film of single-...

Dietary deficiency of trace elements, minerals and vitamins has been associated with severe malnutrition among young children. Although levels of severe malnutrition among children are high in developing countries, data on dietary intake of trace elements, minerals, vitamins and other nutrients by severely malnourished (SMN) children are limited. The present prospective study was conducted for ...

The nutrient composition of “Nduduagworagwo” a traditional food of the Akokwa people was investigated. The recipe showed high crude fats, high carbohydrate and appreciable energy value. Minerals such as sodium, potassium, calcium, magnesium, phosphorus, zinc, and iron were detected in the studied food.The sodium/potassium ratio and calcium/phosphorus ratio were normal as stipulated by National ...

During embryonic and fetal development much of the skeleton initiates as a cartilaginous scaffold, which is progressively resorbed and replaced by bone. Endochondral bone formation continues until the growth plates fuse during puberty. At all life stages adequate delivery of mineral is required for the skeleton to achieve and maintain appropriate mineral content and strength. During fetal devel...

Carbonated hydroxyapatite is the mineral found in vertebrate bones and teeth, whereas invertebrates utilize calcium carbonate in their mineralized organs. In particular, stable amorphous calcium carbonate is found in many crustaceans. Here we report on an unusual, crystalline enamel-like apatite layer found in the mandibles of the arthropod Cherax quadricarinatus (freshwater crayfish). Despite ...

“Stickies” are tacky species, present in recycled paper and coated broke, derived from coating formulations, adhesives etc. They impact negatively on paper quality and cause web runnability problems by deposit build-up. To sustain recycling, stickies are controlled by adsorbing them onto minerals added to the recycled stock. We report isotherms for a fatty acid ester defoamer and an acrylic aci...
