Increased poultry production worldwide has led to higher generation of waste materials. To date, these materials have limited uses and often end up in landfill. Research begun investigate new applications for materials, particularly as fillers functional additives with a range polymers. With oil supplies diminishing, use an otherwise material mitigate depletion rates represents solution that wi...
Osteons, the main organizational components of human compact bone, are cylindrical structures composed layers mineralized collagen fibrils, called lamellae. These lamellae have different orientations, degrees organization, and mineralization where intrafibrillar extrafibrillar minerals intergrown into one continuous network oriented crystals. While cellular activity is clearly source organic ma...
Aim: The aim of the study is to introduce an easy and predictable method for horizontal bone augmentation in maxillary ridge using autologous concentrated growth factors (CGF) enriched graft matrix (sticky bone) versus guided regeneration native collagen membrane Methodology: A total 28 patients presenting with Cawood Class IV classification (2-4mm residual alveolar width) were included study. ...
The desirable physical and physiochemical properties of clay minerals have led them to play a substantial role in pharmaceutical formulations. Clay minerals like kaolin, smectite and palygorskite-sepiolite are among the world's most valuable industrial minerals and of considerable importance. The elemental features of clay minerals which caused them to be used in pharmaceutical formulations are...
Volcanic ash is fragments of magma, and consists of minerals and volcanic glass. These materials in the ash can provide important information on the nature of the magma, because chemical compositions of magma usually show distinct features in each volcano, and because assemblages and compositions of minerals reflect their host melt. Using assemblages and chemical compositions of minerals and gl...
Minerals, as we know them, are locked in the crust of the earth. As land dwellers, our main link with minerals is through a diet of plants, which are able to extract and assimilate metallic minerals from the soil as they grow. Our secondary link is from meats of animals that eat plants. Minerals are extremely important for our well-being, yet they have always been taken for granted, and few of ...
Many postmenopausal women have vitamin D and calcium deficiency. Therefore, vitamin D and calcium supplementation is recommended for all patients with osteopenia and osteoporosis. We used an experimental rat model to test the hypothesis that induction of osteoporosis is more efficiently achieved in peripheral bone through combining ovariectomy with a unique multi-deficiencies diet (vitamin D de...
we assessed the size and composition of the soil seed bank and above-ground vegetation in 52 relevés representing a range of habitats within an old- growth, temperate deciduous forest at hyrcanian region, northern iran. we identified 63 taxa in the seed bank, with an average density of 4202 seeds/spores per m2 by seedling emergence method. hypericum androsaemum, cardamine impatiens, and rub...
Effects of the in ovo injection of organic Mn, Zn, and Cu in association with post-hatch (POH) feed and water restriction on the performance and physical-chemical bone parameters of male Ross × Ross 708 broilers were examined. On 17 d of incubation, a total of 1,872 eggs were subjected to in ovo injection using a commercial multi-egg injector. Treatments (TRT) includingd non-injected and diluen...
