Physical reactions involved in the formation of or changes in the structure of atoms and molecules and their interactions.
Dentin
The hard portion of the tooth surrounding the pulp, covered by enamel on the crown and cementum on the root, which is harder and denser than bone but softer than enamel, and is thus readily abraded when left unprotected. (From Jablonski, Dictionary of Dentistry, 1992)

Dentinal tubule occlusion with lanthanum fluoride and powdered apatite glass ceramics in vitro. (1/221)

To simulate hypersensitive dentin, the smear layer and dentinal plugs of bovine root dentin specimens were removed by immersion in 10% phosphoric acid, polishing with hydroxyapatite particles, and ultrasonic cleansing. The fluoride-tannic acid-lanthanum-apatite (FTLA) group was treated with acidulated phosphate fluoride (APF) containing tannic acid followed by rubbing with a paste of lanthanum chloride (LaCl3) and powdered apatite glass ceramics. The treated specimens were immersed in a remineralizing solution that mimics saliva for 6 weeks. The SEM observations revealed that the treated surfaces of the FTLA group were completely covered with fine spherical compounds and the dentinal tubules were occluded with plugs to a depth of about 3 microns. Fluoride and lanthanum were detected to a depth of over 20 microns by EPMA observation. After the remineralization, the surface of FTLA-treated specimen did not have any opened tubules and showed a remarkable increase in the number of fine spherical deposits in the dentinal tubules. These results suggest that the reaction products produced by sequential treatment with acidic fluoride and LaCl3 and powdered apatite glass ceramics are able to effectively occlude dentinal tubules.  (+info)

Reversible suppression of in vitro biomineralization by activation of protein kinase A. (2/221)

Parathyroid hormone (PTH-(1-34)) potently suppresses apatite deposition in osteoblastic cultures. These inhibitory effects are mediated through signaling events following PTH receptor binding. Using both selective inhibitors and activators of protein kinase A (PKA), this study shows that a transient activation of PKA is sufficient to account for PTH's inhibition of apatite deposition. This inhibition is not a result of reduced cell proliferation, reduced alkaline phosphatase activity, increased collagenase production, or lowering medium pH. Rather, data suggest a functional relationship between matrix assembly and apatite deposition in vitro. Bone sialoprotein (BSP) and apatite co-localize in the extracellular matrix of mineralizing cultures, with matrix deposition of BSP temporally preceding that of apatite. Transient activation of PKA by either PTH-(1-34) or short term cAMP analog treatment blocks the deposition of BSP in the extracellular matrix without a significant reduction in the total amount of BSP synthesized and secreted. This effect is reversible after allowing the cultures to recover in the absence of PKA activators for several days. Thus, a transient activation of PKA may suppress mineral deposition in vitro as a consequence of altering the assembly of an extracellular matrix permissive for apatite formation.  (+info)

Porous apatite-wollastonite glass-ceramic as an intramedullary plug. (3/221)

We evaluated the efficacy and biocompatibility of porous apatite-wollastonite glass ceramic (AW-GC) as an intramedullary plug in total hip replacement (THR) for up to two years in 22 adult beagle dogs. Cylindrical porous AW-GC rods (70% porosity, mean pore size 200 microm) were prepared. Four dogs were killed at 1, 3, 6 and 12 months each and six at 24 months after implantation. Radiological evaluation confirmed the efficacy of porous AW-CG as an intramedullary plug. Histological evaluation showed osteoconduction at one month and resorption of the porous AW-GC, which was replaced by newly-formed bone, at 24 months. Our findings indicate that porous AW-GC can be used clinically as an intramedullary plug in THR.  (+info)

A bone replaceable artificial bone substitute: morphological and physiochemical characterizations. (4/221)

A composite material consisting of carbonate apatite (CAp) and type I atelocollagen (AtCol) (88/12 in wt/wt%) was designed for use as an artificial bone substitute. CAp was synthesized at 58 degrees C by a solution-precipitation method and then heated at either 980 degrees C or 1,200 degrees C. In this study, type I AtCol was purified from bovine tail skins. A CAp-AtCol mixture was prepared by centirfugation and condensed into composite rods or disks. The scanning electron-microscopic (SEM) characterization indicated that the CAp synthesized at 58 degrees C displayed a crystallinity similar to that of natural bone and had a high porosity (mean pore size: about 3-10 microns in diameter). SEM also revealed that the CAp heated at 980 degrees C was more porous than that sintered at 1,200 degrees C, and the 1,200 degrees C-heated particles were more uniformly encapsulated by the AtCol fibers than the 980 degrees C-heated ones. A Fourier transformed-infrared spectroscopic analysis showed that the bands characteristic of carbonate ions were clearly observed in the 58 degrees C-synthesized CAp. To enhance the intramolecular cross-linking between the collagen molecules, CAp-AtCol composites were irradiated by ultraviolet (UV) ray (wave length 254 nm) for 4 hours or vacuum-dried at 150 degrees C for 2 hours. Compared to the non cross-linked composites, the UV-irradiated or dehydrothermally cross-linked composites showed significantly (p < 0.05) low collagen degradation and swelling ratio. Preliminary mechanical data demonstrated that the compressive strengths of the CAp-AtCol composites were higher than the values reported for bone.  (+info)

Augmentation of (pedicle) screws with calcium apatite cement in patients with severe progressive osteoporotic spinal deformities: an innovative technique. (5/221)

Screw augmentation with calcium apatite cement (CAC) was used in seven patients with a progressive osteoporotic spinal deformity. Thirty-nine spinal segments (64 screws) were augmented: 15 anteriorly (three patients) and 24 posteriorly (five patients). Dorsally, hemilaminectomy was performed at the level of all augmented screws to rule out CAC leakage. Autogenous bone graft was applied in all patients to induce fusion. Screw augmentation failure occurred in only one patient: 1 of the 16 ventral augmented screws (5.5%) was still loose after the augmentation procedure. In three other patients, 4 out of 48 augmented dorsal screws (5.5%) showed CAC leakage at the pedicle corpus vertebra level. Pedicle wall damage was present at two levels, while at two other levels no wall damage was found during visualization. No CAC-related complications were observed perioperatively. No implant migration was observed, and fusion was observed in all cases at follow-up examination performed at a mean of 32 months after surgery.  (+info)

Calcification of rachitic rat cartilage in vitro by extracellular matrix vesicles. (6/221)

Growth plate cartilage from rachitic rats was studied to assess the role in calcification of extracellular matrix vesicles, which are thought to participate in the initial stage of mineralization of connective tissue. The concentration of matrix vesicles and their distribution within the longitudinal septa was found to be normal in rats made rachitic by feeding by a diet low in vitamin D and phosphate for 3 weeks after weaning. Rachitic cartilage matrix did not contain circumvesicular clusters of apatite as does normal cartilage; however, occasional vesicles did enclose one or a few apatite needles. When slices of rachitic cartilage were incubated at 37 C in a metastable calcium phosphate solution ([Ca++] times [PO SEE ARTICLE] equals 3.5 mM identical to 2), apatite formation was initiated in association with matrix vesicles. Under these conditions, mineralization was prominent in the upper hypertrophic cartilage, where matrix vesicles became encrusted with apatite after only 2 to 3 hours of incubation. Vesicular apatite accumulation was inhibited by preheating the cartilage to 60 C for 30 minutes. Measurements of 45Ca uptake by rachitic cartilage slices from metastable calcium phosphates solution also indicated inhibition of calcification by heat. Light microscopic autoradiographs showed 45Ca localization primarily in the matrix of longitudinal septa and substantiated the inhibition site of mineralization in healing rachitic cartilage. The presence of apatite within rachitic vesicles prior to heating and the inhibition of vesicle calcification by heat suggests an active, enzymatically and mediated mechanism of vesicular calcification.  (+info)

Modification of electrochemically deposited apatite using supercritical water. (7/221)

Supercritical water was used as a modification method of electrochemically deposited apatite on pure titanium. The apatites were coated on a commercially pure titanium plate using a hydrothermal-electrochemical method. A constant direct current at 12.5 mA/cm2 was loaded for 1 hr at 25, 60, 100, 150 and 200 degrees C in an electrolyte containing calcium and phosphate ions. The deposited apatite on the titanium substrate was stored in supercritical water at 450 degrees C under 45 MPa for 8 hr. With this treatment, the crystallinity of the apatites increased, sharp edges of the deposited apatites were rounded off, and the bonding strength of the titanium substrate to the deposited apatites significantly increased. On the other hand, weight loss in 0.01 N HCl decreased and the weight gain rate in a simulated body fluid also decreased with this treatment. It is suggested that the modification using supercritical water improved the mechanical strength of the deposited apatite, but worsened its bioactivity.  (+info)

Calcium apatite crystals in synovial fluid rice bodies. (8/221)

BACKGROUND: Rice bodies can occur in the joints in many rheumatic conditions, but they are most common in rheumatoid arthritis. They are generally believed to occur rarely in patients with osteoarthritis, but one study reported rice bodies with apatite crystals. OBJECTIVE: To report on a series of joint fluids with rice bodies containing apatite clumps and examine their clinical pictures. METHODS: All synovial fluid analysis reports for 10 years were reviewed for rice bodies and eight patients were reported on. A series of patients with a variety of diseases with synovial fluid rice bodies found to contain calcific material is described. All were examined by compensated polarised light and alizarin red stain, and four were examined by electron microscopy. RESULTS: The eight patients all had alizarin red S chunks embedded throughout the rice body. Transmission electron microscopy disclosed the presence of a matrix of collagen, fibrin, and amorphous materials containing typical apatite crystals. Clinical diagnoses, radiographic findings, and leucocyte counts varied, but six of the eight patients had had previous repeated corticosteroid injections into the joints. CONCLUSION: Aggregates of apatites may be more common than previously recognised in rice bodies as they are not routinely sought. Whether they are a result of joint damage or depot steroid injections and whether that might contribute to further joint injury now needs to be investigated.  (+info)

Factors controlling sulfur concentrations in volcanic apatiteFactors controlling sulfur concentrations in volcanic apatite
Apatite crystals from two types of samples were analyzed by electron microprobe for 15 major and trace elements: (1) apatite in H2O- and S-saturated experimental charges of the 1982 El Chicho??n trachyandesite and (2) apatite in volcanic rocks erupted from 20 volcanoes. The SO3 contents of the experimental apatite increase with increasing oxygen fugacity (fo2), from ???0.04 wt% in reduced charges buffered by fayalite-magnetite-quartz (FMQ), to 1.0-2.6 wt% in oxidized charges buffered by manganosite-hausmanite (MNH) or magnetite-hematite (MTH). The SO3 contents of MNH- and MTH-buffered apatite also generally increase with increasing pressure from 2 to 4 kbar and decreasing temperature from 950 to 800??C. The partition coefficient for SO3 between apatite and oxidized melt increases with decreasing temperature but appears to be independent of pressure. Apatites in volcanic rocks show a wide range of SO3 contents (|0.04 to 0.63 wt%). Our sample set includes one group known to contain primary...

A biodegradable polymer with surface properties that promotes cell attachment and host integration is widely recognized as a useful three-dimensional construct for bone tissue engineering applications. In this work, studies were carried out to correlate surface properties of modified polycaprolactone (PCL) films with cell-material interactions. PCL film substrates were subjected to various degrees of chemical hydrolysis using different pretreatment solutions to introduce different densities of carboxylate groups onto the surfaces. The extent of hydrolysis on the films was optimized to allow the deposition of a dense and uniform bone-like apatite layer by an alternate soak treatment, followed by subsequent incubation in simulated body fluid (SBF). The hydrolyzed and apatite-coated PCL films were investigated using scanning electron microscopy, thin film X-ray diffractometer (TF-XRD), water contact angle, and Alizarin red staining. Surface wettability, roughness, and chemistry of various PCL ...

Crystallisation in fluorapatite-fluorphlogopite glass ceramics - University of Salford Institutional RepositoryCrystallisation in fluorapatite-fluorphlogopite glass ceramics - University of Salford Institutional Repository
Apatite based glass-ceramics are some of the most bioactive materials found to date. They do not require fibrous encapsulation and bond to bone directly through an apatite layer. Apatite based glass-ceramics exhibit relatively poor biaxial flexural strength, hence limiting their applications to non-load bearing implants. The addition of mica results in a material that is highly machinable, and provided that a suitable interlocking microstructure can be produced, the strength will be increased. The aim of this work is to investigate how altering the heat treatment affects the crystallisation and the final mechanical properties of three different compositions of glass-ceramic. The glass system studied is the ternary glass system; barium fluorphlogopite (Bao.sMgafSiaAlOiojFz), fluorapatite (CaiofPO^eFz) and cordierite (MgzAUSisOis). The three compositions differ by the mol% of fluorapatite forming feedstock in the precursor glass. Glass-ceramics formed by heat-treating a glassy precursor are ...

An adherent bioactive calcium phosphate coating is formed on a titanium or titanium alloy substrate by immersing the substrate in an acidic calcium phosphate solution to form a non-apatitic calcium phosphate coating on the substrate. In a second step the coated substrate can be converted to a less reactive coating by being immersed into a basic or neutral solution to convert the coating into an apatite. However if a relatively reactive coating is desired, the second step can be dispensed with.

Simulated body fluid - WikipediaSimulated body fluid - Wikipedia
A simulated body fluid (SBF) is a solution with an ion concentration close to that of human blood plasma, kept under mild conditions of pH and identical physiological temperature. SBF was first introduced by Kokubo et al. in order to evaluate the changes on a surface of a bioactive glass ceramic. Later, cell culture medium (such as DMEM, MEM, α-MEM, etc.), in combination with some methodologies adopted in cell culture, was suggested as an alternative to conventional SBF in assessing the bioactivity of materials. For an artificial material to bond to living bone, the formation of bonelike apatite layer on the surface of an implant is of significant importance. The SBF can be used as an in vitro testing method to study the formation of apatite layer on the surface of implants so as to predict their in vivo bone bioactivity. The consumption of calcium and phosphate ions, present in the SBF solution, results in the spontaneous growth of bone-like apatite nuclei on the surface of biomaterials in ...

Substitution of sulfate in apatite | American Mineralogist | GeoScienceWorldSubstitution of sulfate in apatite | American Mineralogist | GeoScienceWorld
The substitution of sulfate in apatite is of potential importance in synthetic biomaterials used in bone repair and reconstruction. The counter ion (e.g., Na+, K+, Mg2+, Sr2+) in the sulfate reagent may also be used as a source of medically beneficial ions. An understanding of the structural parameters controlling sulfate substitution is also important in expanding our knowledge beyond the substitution of carbonate in apatites.. The incorporation of sulfate in calcium and strontium hydroxylapatites, prepared in aqueous solution at pH 9, was verified by combustion analysis of sulfate, infrared and Raman spectroscopy, and by determination of unit-cell parameters. Sulfate could not be incorporated into barium hydroxylapatite because of the preferential formation of BaSO4.. The amount of sulfate substituted in the apatite was affected by the mole ratio of sulfate to phosphate in the reaction mixture and by the nature of the counter ion in the sulfate reagent. When sodium is the counter ion in the ...

The name apatite comes from the Greek word apate, which means, "to deceive." It could be said apatite had been deceived into allowing itself to be confused with some of the more valuable gems such as tourmaline, olivine, peridot, topaz and beryl. For crystal healers, apatite is a gemstone to clear away the fog left by negative and toxic emotions, letting the chakra pathways to flow more freely.

A new model for examining fission-track data from natural specimens has been developed on the basis of new laboratory data describing fission-track annealing in a wide variety of apatites and the empirical correction for fission-track length anisotropy presented in earlier papers. Using revised and simplified statistical methods, we examine how well various empirical equations are able to fit the laboratory data and reproduce expected behavior on geological time scales. Based on the latter criterion, we find that so-called fanning Arrhenius models of mean track length are not the best-suited for our data. Instead, we find that fitting c-axis projected lengths with a model that incorporates some curvature on an Arrhenius plot produces results that are in better agreement with the available geological benchmarks. In examining the relative annealing behavior of apatites with different resistance to annealing, we find that the laboratory-time-scale behavior of any two apatites can be reproduced ...

Single-phase ceramic samples of silicate apatites M2Ln8(SiO4)6O2 (M = Mg, Ca, Sr; Ln = Y, La) undoped and doped with Eu3+, Ce3+, or Mn2+ ions were obtained by the high-temperature solid-state reaction technique using precursors synthesized under hydrothermal conditions. The phosphors were characterized by XRD analysis, Raman spectroscopy, and steady-state/time-resolved and site-selective photoluminescence spectroscopy under blue-to-VUV excitation. It is shown that the small-radius Mg2+ ions, which can occupy two types of suitable sites in the apatite structure, strongly influence luminescence properties of apatites, in particular the distribution of Eu3+ ions between these sites. A bright broad-band yellow emission (peaked at 560 nm with t , 1 ms) was obtained from the Mg2La8(SiO4)6O2:Eu apatite after annealing it in a H2(15%)/Ar reducing atmosphere. This emission is due to 5d-4f transitions of Eu2+ and is efficiently excited by near UV-to-blue light (300-450 nm). Silicate apatites co-doped with ...

In vivo biomechanical stability of osseointegrating mesoporous TiO2 implantsIn vivo biomechanical stability of osseointegrating mesoporous TiO2 implants
Mesoporous materials are of high interest as implant coatings to receive an enhanced osseointegration. In this study, titanium implants coated with mesoporous TiO(2) thin films have been evaluated both in vitro and in vivo. Material characterization showed that, with partly crystalline TiO(2) (anatase), long-range-ordered hydrophilic mesoporous thin films with a pore size of 6nm were obtained. Evaluation of the mechanical resistance showed that the films were robust enough to withstand the standard implantation procedure. In vitro apatite formation was studied using simulated body fluids, showing that the pores are accessible for ions and that formation of apatite was increased due to the presence of the mesopores. An in vivo study using a rabbit model was executed in which the removal torque and histomorphometry were evaluated. The results show that the biomechanical stability of the TiO(2) coating was unaffected by the presence of mesopores and that osseointegration was achieved without any signs of

Ecographica: July 2009
For example, carbonate apatite - a primary constituent of both skeletal bones and dentition in vertebrates - is incorporated into organisms through diet and water uptake. Some conservationists use the isotopic signatures recovered from this apatite to better decipher the life histories of contemporary species in expectation of aiding in their continued preservation. As a case in point, remains from the worlds largest cavefish (Milyeringa veritas) have been used by Australian conservationists to better examine and comprehend the environment and ecosystem inhabited by the fish. The cavefish resides in deep water columns that are rich in dissolved limestone. Due to relative densities and variable solubility, different depths in the water column are correlated to specific concentrations of dissolved materials. By examining the isotopic signatures of the cavefishs skeletal apatite, conservationists were able to discover the exact depth the fish occupies ...

Nowadays, titanium-based alloys are among the most attractive metallic materials for biomedical applications (as implants) due to their non-biodegradability, low density, good mechanical properties as well as their good biocompatibility. Hydroxyapatite (Ca10 (PO4)6(OH)2, HA) has been widely used for biomedical applications due to its bioactive, biocompatible and osteoconductive properties. Firstly, Ti-6Al-4V alloy was synthesized by mechanical alloy method with high energy ball milling plantery, HEBM. And then in this work began with preparing hydroxyapatite, HA, from bovine bones and continued with composite in nano clay powder .At the end a hydroxyapatite-clay (HA/Clay) nanocomposite ceramic, 80 wt.% of HA and 20 wt.% nano clay powder, was synthesized through a mechanical method , HEBM. The ability of apatite formation on the produced nanocomposite samples, as a yardstick for evaluation of the bioactivity, was estimated by using simulated body fluid.

DOPED APATITE NANOPARTICLES: CHARACTERIZATION AND BIOMEDICAL RELEVANCE by Jessica Marie GregoryDOPED APATITE NANOPARTICLES: CHARACTERIZATION AND BIOMEDICAL RELEVANCE by Jessica Marie Gregory
There is an impending need for alternatives to traditional antibiotics as bacterial strains become increasingly resistant. In the United States alone, the CDC estimates approximately 2 million people are affected by antibiotic resistant bacteria per year, resulting in 23,000 deaths. As an alternative to traditional antibiotics, viruses that specifically target and kill bacteria have been used to treat human bacterial infection. In this work, a treatment delivery system was created for iron-doped apatite nanoparticles (IDANPs) which significantly enhance bacterial killing by these viruses (bacteriophage or phage). This effect has been demonstrated across gram-positive and gram-negative bacterial species as well as with the use of phage of various tail morphology and genetic material. IDANPs must be prepared under specific conditions (25-45 °C, with 30 % iron-doping, and 5.5 mM citrate) in order to cause these significant increases in bacterial death. The synthesis parameters used during IDANP synthesis

ROCK PHOSPHATE - Egypt GlobeROCK PHOSPHATE - Egypt Globe
Rock Phosphate or Phosphate rock is a non-detrital sedimentary rock which contains high amounts of phosphate bearing minerals. The phosphate content of phosphorite is at least 15 to 20%, which is a large enrichment over the typical sedimentary rock content of less than 0.2%. The phosphate is present as fluorapatite Ca5(PO4)3F (CFA) typically in cryptocrystalline masses (grain sizes , 1 μm) referred to as collophane. It is also present as hydroxyapatite Ca5(PO4)3OH, which is often dissolved from vertebrate bones and teeth, whereas fluorapatite can originate from hydrothermal veins. Other sources also include chemically dissolved phosphate minerals from igneous and metamorphic rocks. Phosphorite deposits often occur in extensive layers, which cumulatively cover tens of thousands of square kilometres of the Earths crust.. Limestones and mudstones are common phosphate bearing rocks. Phosphate rich sedimentary rocks can occur in dark brown to black beds, ranging from centimeter sized laminae to ...

Calcium sulfate-bioactive glass (CSBG) composites doped with 5, 10 and 20 mol% Fe were synthesized using quick alkali sol-gel method. X-ray diffraction (XRD) data of samples heated at 700°C revealed the presence of anhydrite, while field emission scanning electron microscopy (FESEM) and energy dispersive X-ray (EDX) characterization confirmed the formation of nano-sized CSBGs. The UV-vis studies confirmed that the main iron species in 5% Fe and 10% Fe doped CSBGs were tetrahedral Fe(III) whereas that in 20% Fe doped CSBG were extra-framework FeOx oligomers or iron oxide phases. Measurement of magnetic properties of the samples by vibrating sample magnetometer (VSM) showed very narrow hysteresis loop with zero coercivity and remanence for 10% Fe and 20% Fe doped CSBG, indicating that they are superparamagnetic in nature. All samples induced the formation of apatite layer with Ca/P ratio close to the stoichiometric HA in simulated body fluid (SBF) assessment. ...

Synthesis of ion-substitued nanosized apatites and assessment of dispersibility and cell culture behaviourSynthesis of ion-substitued nanosized apatites and assessment of dispersibility and cell culture behaviour
The use of hydroxyapatite (HA) based materials is widely spread in the repair of bone tissue and their great acceptance arises from the close similarity of HA to the mineral phase of bone. In the last years HA has been explored in a new area of application where it, in the form of nanoparticles (NPs), has been used as a carrier for the delivery of drugs and genes inside targeted cells. In spite of the promising results, which have been reported up to day, there are fundamental questions that remain unanswered. The goal of this project is to address one specific aspect: if the addition of doping ions in the formulation of hydroxyapatite NPs affects cell behaviour. For this purpose the first objective was to prepare HA NPs with various types and degree of ion substitution: carbonate (CO3)-, magnesium (Mg)- and CO3-Mg-co-substituted HA NPs. They were prepared via a wet precipitation route involving neutralization of calcium hydroxide with phosphoric acid and were characterised by X-ray diffraction ...

The Northern Norrbotten Ore Province in northernmost Sweden includes the type localities for Kiruna-type apatite iron deposits and has been the focus for intense exploration and research related to Fe oxide-Cu-Au mineralisation during the last decades. Several different types of Fe-oxide and Cu-Au ± Fe oxide mineralisation occur in the region and include: stratiform Cu ± Zn ± Pb ± Fe oxide type, iron formations (including BIFs), Kiruna-type apatite iron ore, and epigenetic Cu ± Au ± Fe oxide type which may be further subdivided into different styles of mineralisation, some of them with typical IOCG (Iron Oxide-Copper-Gold) characteristics. Generally, the formation of Fe oxide ± Cu ± Au mineralisation is directly or indirectly dated between ~ 2.1 and 1.75 Ga, thus spanning about 350 m.y. of geological evolution.The current paper will present in more detail the characteristics of certain key deposits, and aims to put the global concepts of Fe-oxide Cu-Au mineralisations into a regional ...

Even the structurally simplest of biological tissues are composite materials: soft tissues are composed of proteins, sugars and water while mineralized (hard) tissues are composed of these components plus a large volume fraction of mineral (a carbonated apatite or dahllite). In mammals the ubiquitous fibrillar protein collagen is the dominant protein present. Due to the composite nature of tissues, there has been considerable recent interest in modeling the structure-properties relationships (particularly in mineralized tissues) in a manner analogous to that used for study of traditional engineering composites.. ...

In order to shed some light on DNA preservation over time in skeletal remains from a physicochemicalviewpoint, adsorption and desorption of DNA on a well characterized synthetic apatite mimicking boneand dentin biominerals were studied. Batch adsorption experiments have been carried out to determinethe effect of contact time (kinetics), DNA concentration (isotherms) and environmentally relevant factorssuch as temperature, ionic strength and pH on the adsorption behavior. The analogy of the nanocrystallinecarbonated apatite used in this work with biological apatite was first demonstrated by XRD, FTIR, andchemical analyses. Then, DNA adsorption kinetics was fitted with the pseudo-first order, pseudo-secondorder, Elovich, Ritchie and double exponential models. The best results were achieved with the Elovichkinetic model. The adsorption isotherms of partially sheared calf thymus DNA conformed satisfacto-rily to Temkins equation which is often used to describe heterogeneous adsorption behavior ...

Basic calcium phosphate (BCP) crystals, including hydroxyapatite, octacalcium phosphate (OCP) and carbonate-apatite, have been associated with severe osteoarthritis and several degenerative arthropathies. Most studies have considered the chondrocyte to be a bystander in the pathogenesis of calcium crystal deposition disease, assuming that synovial cell cytokines were the only triggers of chondrocyte activation. In the present study we identified direct activation of articular chondrocytes by OCP crystals, which are the BCP crystals with the greatest potential for inducing inflammation. OCP crystals induced nitric oxide (NO) production and inducible nitric oxide synthase (NOS) mRNA expression by isolated articular chondrocytes and cartilage fragments, in a dose-dependent manner and with variations over time. OCP crystals also induced IL-1beta mRNA expression. Using pharmacological and cytokine inhibitors, we observed that OCP crystals induced NO production and inducible NOS mRNA activation were regulated

N2 - Fibronectin (Fn) and type I collagen (Col) were immobilized on a surface of a hydroxyapatite (HAP) ceramic by coprecipitation with calcium phosphate in a supersaturated calcium phosphate solution prepared by mixing clinically approved infusion fluids. These proteins and the calcium phosphate precipitate formed a composite surface layer. As a result, the proteins were immobilized firmly as not to be released completely for 3 d in a physiological salt solution. When human mesenchymal stem cells (hMSCs) were cultured on a HAP ceramic in a differentiation medium supplemented with dexamethasone, ...

Overestimate of Lunar Water? - SpaceRefOverestimate of Lunar Water? - SpaceRef
The amount of water present in the moon may have been overestimated by scientists studying the mineral apatite, says a team of researchers led by Jeremy Boyce of the UCLA Department of Earth, Planetary and Space Sciences.. Boyce and his colleagues created a computer model to accurately predict how apatite would have crystallized from cooling bodies of lunar magma early in the moons history. Their simulations revealed that the unusually hydrogen-rich apatite crystals observed in many lunar rock samples may not have formed within a water-rich environment, as was originally expected ...

My study focuses on quantifying and modeling the transport of contaminants from sediments to the water column and on investigating the effectiveness of active capping as a mitigation strategy to minimize the release of these contaminants. Active capping both isolates contaminated sediments from the water phase while offering degradation and/or sequestration of contaminants by the active materials. I modeled the transport of Cd, Cr, Pb, Ag, As, Ba, Hg, CH3Hg and CN through sand (25 cm), granular activated carbon (GAC, 2 cm), organoclay (2 cm), shredded tires (10 cm) and apatite (2 cm) caps by deterministic and Monte Carlo methods. Sand caps performed best under diffusion due to the greater diffusive path length. Apatite had the best advective performance for Cd, Cr and Pb. Organoclay performed best for Ag, As, Ba, CH3Hg and CN. Organoclay and apatite were equally effective for Hg. Monte Carlo analysis was used to determine output sensitivity. Sand was effective under diffusion for Cr within the ...

Biocompatible and bioactive calcium phosphates can make chemical bonds with living bones. Improvement of their biological and physicochemical properties can be achieved by doping with various ions that are presented in natural apatites of bones. These substitutions influence lattice parameters, structure and morphology of apatites. In recent times great attention has been devoted to zinc ions that are the second most abundant trace element present in bones. Zinc embedded into calcium phosphate may enhance the bone formation and in addition exhibits antifungal and antibacterial properties. Therefore, it is rational to form structures incorporated with this ion. In this paper the incorporation of the Zn ions into natural and synthetic calcium phosphates has been reported.Natural hydroxyapatites (HAs) applied in this study were derived mainly from pork bones whereas both brushite and synthetic were formed using wet chemical methods. Ambient temperature synthesis leads to the formation ofbrushite, ...

Phosphorus and iron cycling in deep saprolite, Luquillo Mountains, Puerto Rico | LCZO-Data
Rapid weathering and erosion rates in mountainous tropical watersheds lead to highly variable soil and saprolite thicknesses which in turn impact nutrient fluxes and biological populations. In the Luquillo Mountains of Puerto Rico, a 5-m thick saprolite contains high microorganism densities at the surface and at depth overlying bedrock. We test the hypotheses that the organisms at depth are limited by the availability of two nutrients, P and Fe. Many tropical soils are P-limited, rather than N-limited, and dissolution of apatite is the dominant source of P. We document patterns of apatite weathering and of bioavailable Fe derived from the weathering of primary minerals hornblende and biotite in cores augered to 7.5 m on a ridgetop as compared to spheroidally weathering bedrock sampled in a nearby roadcut. Iron isotopic compositions of 0.5 N HCl extracts of soil and saprolite range from about δ56Fe=0 to −0.1‰ throughout the saprolite except at the surface and at 5 m depth where ...

The Tyler Shale: Waste Overburden or Phosphate Ore? | Wisconsin Citizens Media CooperativeThe Tyler Shale: Waste Overburden or Phosphate Ore? | Wisconsin Citizens Media Cooperative
Frank: Thank you for the comment. It is hard to answer your question because GTAC has not been very forthcoming about what its plans actually are. There are two end-members of a range of possibilities. At one end, it is possible that everything GTAC has said is true, that it has not looked at the cores, that it has no idea what is in they Tyler shale, and that this is an iron mine pure and simple. In that case the mine will uncover pyrite and apatite in the process of recovering the iron, which is a problem that has not been discussed at all by either by GTAC or the legislators. The whole rationale for creating separate laws to cover the mining of iron oxides is that iron oxide mining will not uncover sulfides. The presence of sulfides in the Tyler undermines this rationale. At the other extreme is the possibility that GTAC knows exactly what is in the Tyler and is hiding it, either to prevent the issue of sulfides being raised during debate over a bill that creates an artificial distinction ...

Compactation in sedimentary basinsCompactation in sedimentary basins
Subsidence analysis is an important technique in the study of sedimentary basins but the effects of compaction must be backstripped. The compaction of sediments is also of importance for petroleum and water reservoir research with very important economic derivations. Most methods for calculating compaction are based on empirically derived porosity-depth relationships from a variety of known sediment types. The challenge of this paper is to apply alternative methods for calculating compaction in sedimentary basins based on: physical calculation with elastic by Steinbrenner, oedometric and change of the specific weight of the sediment methods; and use of Loadcap software.. The Triassic to Lower Miocene 3025m thick succession of Sierra Espuña (SE Spain) is used as case study for the calculations. In this succession former mineralogical studies and apatite fission-track suggested an original thickness between 4 and 6km. The validity of each one of the proposed methods is discussed, as well as, ...
