Bone Demineralization Technique: Removal of mineral constituents or salts from bone or bone tissue. Demineralization is used as a method of studying bone strength and bone chemistry.Bone Demineralization, Pathologic: Decrease, loss, or removal of the mineral constituents of bones. Temporary loss of bone mineral content is especially associated with space flight, weightlessness, and extended immobilization. OSTEOPOROSIS is permanent, includes reduction of total bone mass, and is associated with increased rate of fractures. CALCIFICATION, PHYSIOLOGIC is the process of bone remineralizing. (From Dorland, 27th ed; Stedman, 25th ed; Nicogossian, Space Physiology and Medicine, 2d ed, pp327-33)Tooth Demineralization: A tooth's loss of minerals, such as calcium in hydroxyapatite from the tooth matrix, caused by acidic exposure. An example of the occurrence of demineralization is in the formation of dental caries.Dental Enamel: A hard thin translucent layer of calcified substance which envelops and protects the dentin of the crown of the tooth. It is the hardest substance in the body and is almost entirely composed of calcium salts. Under the microscope, it is composed of thin rods (enamel prisms) held together by cementing substance, and surrounded by an enamel sheath. (From Jablonski, Dictionary of Dentistry, 1992, p286)Bone and Bones: A specialized CONNECTIVE TISSUE that is the main constituent of the SKELETON. The principle cellular component of bone is comprised of OSTEOBLASTS; OSTEOCYTES; and OSTEOCLASTS, while FIBRILLAR COLLAGENS and hydroxyapatite crystals form the BONE MATRIX.Tooth Remineralization: Therapeutic technique for replacement of minerals in partially decalcified teeth.Hardness Tests: A test to determine the relative hardness of a metal, mineral, or other material according to one of several scales, such as Brinell, Mohs, Rockwell, Vickers, or Shore.

The process of bone remodeling takes place in the adult skeleton at discrete foci. The process ensures the mechanical integrity of the skeleton throughout life and plays an important role in calcium HOMEOSTASIS. An imbalance in the regulation of bone remodeling's two contrasting events, bone resorption and bone formation, results in many of the metabolic bone diseases, such as OSTEOPOROSIS.Bone Matrix: Extracellular substance of bone tissue consisting of COLLAGEN fibers, ground substance, and inorganic crystalline minerals and salts.Spine: The spinal or vertebral column.Osteogenesis: The process of bone formation.

Xenogenic demineralized bone matrix: osteoinduction and influence of associated skeletal defects in heterotopic bone formation in rats. (1/35)

Demineralized bone matrix (DBM) was ectopically implanted in 36 male Wistar rats. In 18 of the animals a bone defect in the femoral condyles was also created: the left was filled with DBM and the right was left empty as a control. The animals were killed after 2, 4 and 6 weeks and new bone was histologically evaluated, comparing ectopic bone formation with or without distant bone injury. Results showed: (1) osteoinductivity of xenogenic DBM, and (2) earlier mineralization of ectopically implanted DBM in the group with associated skeletal injury. Our results show that xenogenic bone matrix acts as an osteoinductive material and that skeletal injury improves osteogenesis at distant sites.  (+info)

The correlation between immune rejection and osteoinduction of allogeneic bone grafting. (2/35)

OBJECTIVE: To evaluate the relationship between the immune rejection and the osteoinductive potential of bone allograft. METHODS: Allogeneic and syngeneic fresh bone, autolyzed antigen-extracted bone, bone matrix gelatin and demineralized bone matrix were implanted into the muscle of mice, and immunological tests, histological observation and alkaline phosphatase assay were performed. RESULTS: Three and 6 weeks after implantation, all kinds of allogeneic implants activated immune rejection, among them, fresh bone induced the most vigorous immune rejection and bone matrix gelatin caused the weakest response. Allogeneic autolyzed antigen-extracted bone, bone matrix gelatin and demineralized bone matrix inhibited proliferation of the lymphocytes in vitro and bone matrix gelatin had the most powerful inhibiting effect. Both allogeneic and syngeneic autolyzed antigen-extracted bone, bone matrix gelatin, and demineralized bone matrix induced heterotopic osteogenesis in vivo and bone matrix gelatin had the best osteoinductive capacity. CONCLUSION: There is a negative correlation between immune rejection to bone allograft and osteoinductive capacity of the graft.  (+info)

Demineralized bone matrix, bone morphogenetic proteins, and animal models of spine fusion: an overview. (3/35)

Preclinical investigations on the use of bone morphogenetic proteins (BMP) in the spine have yielded promising results. This has led to the preliminary introduction of these growth factors in controlled clinical trials. Initial data made available suggest that these differentiating factors will play a major role in the treatment of spinal disorders in the future. This article reviews key preclinical studies and their results that formed the basis for introduction into clinical trials. Non-primate and non-human primate models of spine fusion with BMP are reviewed objectively, and important issues regarding carrier, dose, and site of implantation are discussed. Finally, exciting new gene therapy research is discussed, with comments made on its applicability for the future.  (+info)

In vitro release of vancomycin from vancomycin-loaded blood coated demineralised bone. (5/35)

In vitro and in vivo studies have demonstrated the possibility that cancellous bone could be used as a carrier of antibiotics for local delivery. However, the release of antibiotics from the loaded cancellous bone is too rapid and uncertain. We hypothesised that demineralisation of cancellous bone would increase the amount of antibiotic adsorbed, and coating of the freeze-dried antibiotic-impregnated cancellous bone with bio-compatible material would prolong antibiotic release. Bovine cancellous bone blocks of equal size were demineralised using a 0.5 N HCl solution and loaded with vancomycin solution under vacuum. The loaded bone blocks were then freeze-dried. To obtain a bio-compatible coating, the vancomycin-impregnated bone blocks were soaked in fresh human venous blood for 3 h. The release of impregnated antibiotic from the bone blocks was evaluated in phosphate-buffered saline and foetal bovine serum. It was found that significantly larger amounts of vancomycin were adsorbed into the demineralised bone blocks than into the un-demineralised blocks. The blood coating was found to increase the duration of vancomycin release from the blocks. With demineralisation and blood coating, the blocks eluted vancomycin higher than therapeutic concentration for a 5-week period.  (+info)

Efficacy of contained metaphyseal and periarticular defects treated with two different demineralized bone matrix allografts. (6/35)

The efficacies of two different allografts, Grafton (demineralized bone matrix [DBM] in a glycerol carrier) and Orthoblast (DBM in a reverse thermal poloxamer carrier) were examined from cases involving periarticular fractures. Demographic, perioperative, and outcome data for patients with periarticular fractures who underwent a prospectively designed protocol for bone grafting were compiled, with 15 cases using Orthoblast and 13 using Grafton. A successful graft was defined as healing on the first graft attempt without complications. Healing was determined by radiographic studies and clinical evaluation. The successful graft rates of Orthoblast and Grafton were 15/15 and 9/13, respectively.  (+info)

Evidence for a serum factor that initiates the re-calcification of demineralized bone. (7/35)

The present studies show for the first time that demineralized bone re-calcifies rapidly when incubated at 37 degrees C in rat serum: re-calcification can be demonstrated by Alizarin Red and von Kossa stains, by depletion of serum calcium, and by uptake of calcium and phosphate by bone matrix. Re-calcification is specific for the type I collagen matrix structures that were calcified in the original bone, with no evidence for calcification in periosteum or cartilage. Re-calcification ceases when the amount of calcium and phosphate introduced into the matrix is comparable to that present in the original bone prior to demineralization, and the re-calcified bone is palpably hard. Re-calcified bone mineral is comparable to the original bone mineral in calcium to phosphate ratio and in Fourier transform infrared and x-ray diffraction spectra. The serum activity responsible for re-calcification is sufficiently potent that the addition of only 1.5% serum to Dulbecco's modified Eagle's medium causes bone re-calcification. This putative serum calcification factor has an apparent molecular mass of 55-150 kDa and is inactivated by trypsin or chymotrypsin. The serum calcification factor must act on bone for 12 h before re-calcification can be detected by Alizarin Red or von Kossa staining and before the subsequent growth of calcification will occur in the absence of serum. The speed, matrix-type specificity, and extent of the serum-induced re-calcification of demineralized bone suggest that the serum calcification factor identified in these studies may participate in the normal calcification of bone.  (+info)

Demineralized bone alters expression of Wnt network components during chondroinduction of post-natal fibroblasts. (8/35)

OBJECTIVE: The Wnt family of secreted proteins, their receptors (Fzd proteins) and antagonists (secreted Fzd-related proteins, or Sfrp) regulate chondrocyte differentiation and chrondrogenesis during embryonic development. Here, the hypothesis that the Wnt regulatory network contributes to chondrocyte differentiation of post-natal cells was tested in an in vitro model of chondroinduction by demineralized bone powder (DBP). DESIGN: Human dermal fibroblasts (hDFs) were cultured in porous, three-dimensional (3D) collagen sponges with or without chondroinductive DBP. In some experiments, lithium chloride (LiCl), an agonist of the Wnt/beta-catenin signaling pathway, was added to the culture media. Sponges were cultured for intervals (0.5-21 days) before processing for molecular, histologic, and biochemical analyses. Expression of wnt, fzd, and sfrp genes was characterized by semi-quantitative RT-PCR. Fibroblasts' contacts with DBP were documented by histology. Accumulation of proteoglycan in extracellular matrix was evaluated by histology (metachromasia in toluidine blue-stained sections) and quantitative immunoassay (chondroitin 4-sulfate ELISA). RESULTS: Expression of 15 wnt, fzd, and sfrp family members was detected in hDFs by RT-PCR. A subset of those genes (wnt2b, wnt5b, wnt10b, fzd6, fzd7) showed altered expression in hDFs exposed to DBP for 3 days. wnt and fzd gene expression was not altered before hDFs contacted the DBP within the collagen sponge. Human DFs cultured in plain collagen sponges and treated with LiCl accumulated significantly more metachromatic matrix than NaCl-treated controls on day 10, and showed a trend towards increased matrix chondroitin-4 sulfate content. CONCLUSIONS: These data suggest that changes in Wnt signaling contribute to chondroinduction of post-natal fibroblasts by DBP. This is the first evidence that Wnt components, which are essential regulators of pre-natal chondrocyte differentiation, may also influence post-natal chondrocyte differentiation induced by DBP.  (+info)

But silicas most important use to man is as a nutrient.. Silica promotes the synthesis of the proteins collagen (Type 1) and elastin. Collagen is an abundant protein in mammals, making up the majority of connective tissue like cartilage, tendons, ligaments, gums and skin. Elastin is a stretchy protein, important for healthy skin, lungs and arteries (especially the aorta). Silica also promotes stronger thicker hair, stronger nails, and stronger bones. Although silica only makes up a tiny proportion of bone, its important for promoting re-calcification of bone and speeding healing of fractures. As we age the silica content of our tissues decreases, especially for post-menopausal women ...

N2 - BACKGROUND: Arterial stiffening is one of the hallmarks of vascular aging, and is an important risk factor for cardiovascular morbidity and mortality. Aging is also associated with bone demineralization. Accumulating evidence indicate that arterial stiffness and bone demineralization might share common pathways. The aims of this study were to evaluate whether the association between arterial stiffness and bone demineralization is independent of age, and to explore putative mechanisms that may mediate their relationship. METHODS: A cross-sectional analysis was performed using data from 321 men (68 ± 12 years) and 312 women (65 ± 13 years) of the ...
Symptomatic osteochondral lesions occur frequently, but relatively few treatment options are currently available. The purpose of this study was to conduct a preliminary investigation into a new tissue engineering approach to osteochondral regeneration. The concept is a biphasic construct consisting of a porous, osteoconductive chitosan-calcium phosphate scaffold supporting a layer of neocartilage formed by marrow-derived mesenchymal stem cells. Two experiments were conducted to assess the feasibility of this approach. The first experiment characterized the attachment efficiency and proliferation of primary human marrow-derived mesenchymal stem cells seeded relatively sparely onto the scaffolds surface. The second experiment compared two different methods of creating a biphasic construct using a much higher density of primary porcine marrow stromal cells. About 40% of the sparsely seeded human cells attached and proliferated rapidly. Constructs formed by one of the two experimental techniques ...

A unicameral bone cyst, also known as a simple bone cyst, is a cavity filled with a yellow-colored fluid. It is considered to be benign since it does not spread beyond the bone. Unicameral bone cysts can be classified into two categories: active and latent. An active cyst is adjacent to the epiphyseal plate and tends to grow until it fills the entire diaphysis, the shaft, of the bone; depending on the invasiveness of the cyst, it can cause a pathological fracture or even destroy the epiphyseal plate leading to the permanent shortening of the bone. A latent cyst is located away from the epiphyseal plate and is more likely to heal with treatment. It is typically diagnosed in children from the aged 5 to 15. Although unicameral bone cysts can form in any bone structure, it is predominantly found in the proximal humerus and proximal femur; additionally, it affects males twice as often as females. Most unicameral bone cysts do not cause any symptoms and are discovered as accidental findings on ...

Das Bone Morphogenetic Protein 2 (BMP2) gehört zur TGF-beta Superfamilie und findet seinen Fokus in der osteogenen Aktivierung und in der Anwendung bei der Frakturheilung. Es wird angenommen, dass weitere, bisher unbekannte Verbindungen existieren, die die BMP2-Signalübertragung und die osteogene Aktivität verbessern und somit zu einer verbesserten klinischen Wirksamkeit von BMP2 führen. Für den Stickstoffoxid (NO)-Signalweg ist bereits bekannt, dass im endothelialen Kontext eine Verbindung zum BMP2-Signalweg existiert. Ziel dieser Arbeit war es daher, eine Verbindung zwischen dem NO- und BMP2-Signalweg bezüglich der Regulierung des BMP2-abhängigen Signalwegs und der Osteoinduktion aufzuzeigen. Dies erfolgte durch Anwendung von Inhibitoren (LNAME, ODQ und LY83583) und Aktivatoren (L-Arginin, Deta NONOate, SNAP und YC-1) des NO-Signalwegs, in Kombination mit BMP2. Eine mögliche Verbindung zwischen dem BMP2- und NO-Signalweg, über eine Protein Kinase A (PKA) Brücke, wurde durch die ...
Consider that you may have a card putting 15dBm (32mW) into a 2.2dBi antenna (on the AP), and thatyour card probably has an effective 2dBi gain antenna on it. Operating at 2.4GHz, at 1m, thereis 41dB of path loss between the two units. At 2m, youll have another 6dB of path loss, for 47dB.So the signal leaves at 17dBm (from the AP), you lose 41dB due to LOS (Line of Sight) path lossat 1m, and the signal arrives at the antenna in your laptop at perhaps -24dBm, and is raisedto -22dBm by the antenna.This is quite close to the maximum signal level of 802.11g ...

Several studies demonstrated that the use of graft material has better clinical results for the treatment of intrabony defects. The purpose of this study is to compare the clinical and radiographic efficacy of alloplast (Biphasic calcium phosphate) and demineralized freeze-dried bone allograft (DFDBA) in treatment of periodontal intraosseous defects. A split mouth study was conducted in 20 subjects diagnosed with chronic periodontitis presenting atleast two intrabony defects in either arch. One quadrant (Site A) received alloplast (Biphasic calcium phosphate) and the contralateral defect (Site B) received DFDBA. The results of study showed that clinically Site B (DFDBA) showed greater reduction in pocket depth and gain in clinical attachment level than site A (Biphasic calcium phosphate), however it was not statistically significant. Site A (Biphasic calcium phosphate) showed slightly more gingival marginal recession than Site B (DFDBA). Radiographically Site B (DFDBA) showed greater bone fill ...

Many bone cysts will eventually heal without the need for treatment and wont cause long-term problems - particularly unicameral bone cysts in children, which will usually disappear by the time they stop growing.. If a bone cyst does not get better, or if treatment is recommended to help reduce the risk of a fracture, several options may be available.. For example, steroid medication can be injected into the bone to encourage the cyst to heal. If this doesnt help, surgery may be needed to drain the fluid and fill the hole with chips of bone.. There is a significant chance of the cyst recurring after treatment, so you may need to have regular X-rays for a few years afterwards to look for signs of the condition returning..

dBm - dB referenced to 1 milliwatt. To convert into an equivalent voltage level, the impedance must be specified. For example, 0 dBm into 600 ohms gives an equivalent voltage level of 0.775V, or 0 dBu; however, 0 dBm into 50 ohms, for instance yields an equivalent voltage of 0.24 V. Since modern audio engineering is concerned with voltage levels, as opposed to power levels in the early years of telephone, the convention of using a reference level of 0 dBm is academic. But in the A/V industry, many people still refer to 0.775Vrms (600 r) as 0 dBm, which should be more accurately called 0dBu. ...

This retrospective study evaluated the efficacy of minimally invasive surgery to control cyst progression for active unicameral bone cysts (AUBC) by intracystic methylprednisolone injection, percutaneous curettage, and autogenous bone marrow grafting. From May 2010 to May 2017, patients diagnosed with AUBC who underwent percutaneous double-needle intracystic methylprednisolone injection, percutaneous curettage, and autogenous bone marrow grafting were retrospectively reviewed. Recurrence was defined by modified Neer scale score. Patients were followed up regularly, and previous imaging findings were compared to evaluate treatment efficacy. The 26 patients (17 boys, 9 girls, mean age, 9.4 ± 3.1 years) were followed up for a mean 45.1 months (range, 24-82 months). Follow-up consisted of clinical evaluation and radiographic review. Twenty patients (77%) achieved latent disease stage after the first treatment, while six (23%) achieved it after the second treatment. Postoperative pathological fracture
Tyrannosaurus ( or , meaning tyrant lizard) from the Greek words τυράννος (tyrannos, meaning "tyrant") and σαύρος (sauros, meaning "lizard"), is a genus of theropod dinosaur. The species Tyrannosaurus rex (rex meaning king in Latin), commonly abbreviated to T. rex, is a fixture in popular culture. It lived throughout what is now western North America, with a much wider range than other tyrannosaurids. Fossils are found in a variety of rock formations dating to the last two million years of the Cretaceous Period, 67 to 65.5 million years ago. It was among the last non-avian dinosaurs to exist prior to the Cretaceous-Tertiary extinction event.. Like other tyrannosaurids, Tyrannosaurus was a biped carnivore with a massive skull balanced by a long, heavy tail. Relative to the large and powerful hindlimbs, Tyrannosaurus forelimbs were small, though unusually powerful for their size, and bore two clawed digits.

A method by which immune responses to cortical bone grafts and other substrates (e.g., cement, IPN, etc.) can be minimized and at the same time graft osteoinductive potential can be improved, and improved graft substrate materials are disclosed. The method of the invention provides new types of bone grafts that incorporate into host bone more thoroughly and more rapidly, eliminating long-term complications, such as fracture, non-union, infection, and rejection. In the method of the invention, bone grafts or other substrates are modified to have an osteoinductive surface modification that the recipients body will accept as its own tissue type and therefore will not reject or otherwise cause to fail. The osteoinductive surface modification comprises a biopolymer matrix coating that is seeded with periosteal cells that have been previously harvested either from the graft recipient or from an allogenic or xenogenic donor source.

WHETHER tyrannosaurs occupied predatory or scavenging niches has been debated for nearly a century1-5. Palaeontologists have turned to the study of dental morphology to address this question, but the results have been highly disparate. Some contend that the tyrannosaur dentition was very strong and well suited for engaging and killing herbivorous dinosaurs6,7. Others posit that tyrannosaurs ate carrion, because their teeth and/or jaws would fail during struggles with prey2,3. The discovery of skeletal remains with bite marks from Tyrannosaurus rex8makes it possible to estimate, through indentation simulations on bovine ilia, the bite forces produced by T. rexduring feeding. The estimates (6,410 to 13,400 N) rival the largest bite forces determined for any taxon to date and suggest that T. rex had very strong, impact-resistant teeth. Although these data do not prove that T. rex was predominantly predacious, they indicate that its dentition could probably withstand the stresses associated with prey

6) Promotes good eyesight. Rich in vitamin A as well as beta-carotene, chives ensure the health of our eyesight. Lutein and zeaxanthin, antioxidants with vitamin A activity, protect the macula lutea area and the retina from harmful free radicals from light and are said to contribute to lowering macular degeneration risks (loss of central vision).. 7) Increases calcium absorption in bones. Chives are an incredible source of vitamin K, a nutrient known to increase calcium absorption in bones. By preventing hormonal imbalances leading to bone demineralization, vitamin K preserves bone integrity and bone health. Moreover, a healthy intake also prevents arterial calcification and its aftermath, atherosclerosis.. 8) Reduces inflammation levels. Rich in vitamins C and K, two potent natural anti-inflammatory vitamins, chives are efficient at reducing inflammation levels levels in the body. According to research, high inflammation levels play a big part in the onset of chronic diseases such as diabetes, ...

A textured, demineralized, and unitary mammalian bone section for providing a rigid, foraminous, collagen scaffold for allogenic skeletal reconstruction. The allograft is prepared by treating a section of cadaver bone to remove all soft tissue, then texturing the bone surface to produce a pattern of holes of selected size, density, and depth, and finally demineralizing the bone section to leave a rigid, insoluble collagen scaffold suitable for osteoinduction upon implantation. All such steps are performed with minimal denaturing of the extracellular matrix proteins which remain bound to the collagen scaffold and which are necessary to complete the process of new bone formation.

Tyrannosaurus rex appears to have undergone a proximal-distal suppression of growth in the forelimbs where the arm apparently weakens the farther you travel down it, from the humerus to the phalanges. Make note that this supposedly is documented in lizards that are on the verge of becoming limbless. Now in the last decade or so, it has been made a big deal out of the fact that this particular tyrannosaurid could supposedly curl 400 + lbs in one arm. However, Bakker noted last year in our tyrannosaur symposium that the fingertips of this species could only produce a mere 0.2 horsepower in a spasm. Now of course if we were to leave it there, it would seem that these arms were vestigial. Another contemporary, the Edmontosaurus can apparently produce in a spurt a force of 35 horsepower around the rump region. The result of such an athletic contest is clear: those arms of our rexy are coming clean off in the next five seconds once it grabs its struggling prey ...

A demineralized bone matrix is produced by a process in which a bone body is placed in a first processing solution comprising an acid to demineralize the bone body. The bone body is periodically removed from the first solution at specific time intervals to perform at least one test, such as a compression test, on a mechanical property of the bone body. When the test yields a desired result, the bone body is exposed to a second processing solution that is less acidic than the first, thus minimizing the exposure of the bone body to the harsh acidic conditions of the demineralization phase of the process.

URBAN, South Africa, July 23 - At S Cemetery in Umlazi Township, Innocent Gasas handiwork is everywhere: endless mounds of fresh red earth topped with headstones, unpainted wooden crosses, or, for the most miserable, bricks bearing a painted identifying number. Mr. Gasa has dug graves on this lumpy, unkempt, Halloween-spooky hilltop for two years now, five holes a week, 52 weeks a year, well over 500 holes in all. Which may seem peculiar, seeing as S Cemetery exhausted its last space for new graves five years ago. City records sum up its status succinctly, even dismissively: "Full." But in Durban, "full is a term of art. This city is being battered by an AIDS pandemic so sweeping that people are dying faster than the city can find space to bury them. And so gravediggers like Mr. Gasa are reopening existing graves - the city calls it "recycling - and interring fresh bones atop the old ones. The job gives Mr. Gasa nightmares.

Without regular use, the muscles weaken and slowly deteriorate, a process called atrophy. Disuse also causes the bones to degenerate and weaken. In microgravity, the musculoskeletal system is not used as intensively as it is on Earth, which causes a reduction of bone and muscle strength and size, particularly in the bones and muscles that are used to support the body against gravity. Muscle atrophy results in a loss of lean body mass, a decrease of muscle mass in gravity-bearing muscles, and decreased muscle strength. Bone demineralization results in a loss of calcium and bone density. To study the changes in bones and muscles in space, measurements of protein and calcium metabolism are made. Exposure to microgravity produces a negative calcium and nitrogen balance in the musculoskeletal system. Non-invasive imaging methods, like Magnetic Resonance Imaging (MRI), can be used to study the structural changes in bone and muscle after exposure to microgravity. The long-duration Mir missions allowed ...
Researchers say the identification of the oldest basal (primitive) tyrannosauroid yet will shed light on the early evolution and geographical distribution of its ancestors-small therapod dinosaurs known as coelurosaurs that were the closest relatives of modern-day birds.. Its not only the oldest tyrannosaur but also the sexiest, Erickson said, what with its flashy crest atop its small head-an extravagant ornament likely used only for attraction and display purposes and the first of its kind seen in the tyrannosaurs predatory family. The creature has been named Guanlong wucaii and translated loosely from Chinese, thats crowned dragon five colors.. An internationally known expert on the development and evolution of the vertebrate musculoskeletal system, Erickson helped confirm the tyrannosauroid lineage of the two specimens by noting, among other features, the characteristic long hip, the U-shaped teeth and the fused nasal bridge. While they werent exactly T. rex look-alikes, they were ...
Symptoms of short-term vitamin D toxicity are due to high calcium levels (also known as hypercalcemia) and include confusion, increased urination, increased thirst, loss of appetite, vomiting, and muscle weakness. Acute hypercalcemia may intensify tendencies for heart arrhythmias and seizures and may increase the effects of certain heart drugs. Long-term toxicity may cause kidney failure, increase in calcium deposits in the blood and soft tissue, bone demineralization and pain. Patients with conditions such as liver disease or chronic kidney failure may be at increased risk for developing vitamin D toxicity ...

And its not as though there was only one period of prehistoric creatures. The fossil record shows beyond doubt that there were numerous distinct periods. The therapsids lived before the dinosaurs; the dinosaurs lived before the mammoths. And even among dinosaurs, different layers of rock reveal distinct eras. Stegosaurus, Brachiosaurus and Allosaurus are never found in the same layers of rock as Tyrannosaurus rex, Triceratops, and Velociraptor. The conclusion is that each existed in a different period; the former lived in a period which has been termed the Jurassic, while the latter lived in the Cretaceous period. This is not part of some evil conspiracy by scientists, nor the result of mistakes on their part. Any paleontologist could win instant fame by finding a Tyrannosaurus rex fossil in Jurassic rocks - but nobody has ever done so, which shows that T-Rex lived much later, in the Cretaceous. ...
Bone grafts used in periodontal bony defects with detailed description of autograft, isograft, allograft, xenograft, alloplast and composite grafts. Concept of osteogenesis, osteoconduction, osteoinduction, osteopromotion and bone fill.
There is an urgent need of synthetic bone grafts with enhanced osteogenic capacity. This can be achieved by combining biomaterials with exogenous growth factors, which however can have numerous undesired side effects, but also by tuning the intrinsic biomaterial properties. In a previous study, we showed the synergistic effect of nanostructure and pore architecture of biomimetic calcium deficient hydroxyapatite (CDHA) scaffolds in enhancing osteoinduction, i.e. fostering the differentiation of mesenchymal stem cells to bone forming cells. This was demonstrated by assessing bone formation after implanting the scaffolds intramuscularly. The present study goes one step forward, since it analyzes the effect of the geometrical features of the same CDHA scaffolds, obtained either by 3D-printing or by foaming, on the osteogenic potential and resorption behaviour in a bony environment. After 6 and 12 weeks of intraosseous implantation, both bone formation and material degradation had been drastically ...

The dBm figure is the power related to a specific carrier bandwidth.(BW). Normaly, for a carrier , this is the power in the 3 dB bandwidth.. If you use a spectrum analyser to measure the carrier power, you must make sure to use a resolution bandwidth which is greater than the carrier BW, but not so wide it takes in the power of any adjacent carrier.. With the digital spec. ana. it is possible to set up line markers to measure the total power between ther markes. (In the old days you had to use the calculator to figure this out). A single forward bearer type has been chosen for use in the narrow beam. This bearer has a bandwidth of 189 kHz and uses 16 QAM modulation with a bit rate of 200-492kbps. (F80T4.5X). If the C/N0 is 69.5 dBHz: (Bear in mind that this figure is (negative dB) -69,5 dBHz). The power in the bearer is: -69.5 + (10log189K) =, -69,5 + 52,7 = -16,7 dBm. Additional comments to the discussion dBm and dBHz. The term log means logarithm with base 10. The acronym dB stands for ...

BACKGROUND: The purpose of this study was to compare the outcome of percutaneous curettage with intralesional injection of methylprednisolone and bone marrow for unicameral bone cysts (UBCs). METHODS: This was a retrospective review of 46 children and adolescents with UBC treated with autologous bone marrow injection, methylprednisolone acetate injection or percutaneous curettage alone. Inclusion criteria were a radiological diagnosis of UBC and at least 24 months follow-up from the last procedure. Healing was determined using Neer/Cole 4-grades rating scale. RESULTS: The 3 treatment groups were comparable with regard to age, sex, location of the cyst, and the number of procedures undertaken. At 2 years follow-up, the proportion of patients with satisfactory healing (Neer/Cole grades I and II) was greatest among those who underwent percutaneous curettage (70%) compared with bone marrow injection (21%) and methylprednisolone acetate injection (41%) (P = 0.03). We found no association between healing and

Once a diagnosis is made, optimally, the veterinarian and farrier will work together to come up with a shoeing regimen/prescription. For example, the veterinarian may prescribe nonsteroidal anti-inflammatory agents (NSAIDS), and, while consulting with the farrier for his/her input, they will arrive at a shoeing regimen that will vary according to the needs of the animal. Severe or chronic sole bruising must be minimized. I always recommend an aluminum shoe since aluminum absorbs more concussion than steel. It is sole concussion that initiates the inflammatory process responsible for bone demineralization and periosteal proliferation. These horses also benefit from the use of sole-toughening agents such as a combination of iodine and formaldehyde in a 1:1 solution concentration. Commercial products like Durasole can be employed by the farrier and client. In an effort to minimize the forces of weight bearing on the sole, I have seen egg bar shoes prescribed with a sole trimmed to achieve a deep ...
FES is designed to stimulate muscles and thus improve the function of the extremities. FES has primarily been investigated in individuals with neurologic impairment, most prominently following SCI, stroke or multiple sclerosis. The stimulation is directed at improving function by utilizing devices intended to restore ambulation in the lower extremity or dexterity and function in the upper extremity; or devices to indirectly improve function, such as exercise devices adapted to FES, which are designed to prevent or treat muscle disuse atrophy. The majority of these devices use surface electrodes, but intramuscular (IM) electrodes have also been used. Standard therapy in individuals with neurologic impairment includes active and passive physiotherapy and the use of various braces and orthoses. Therefore, studies were reviewed that investigate the outcomes of FES compared to these standard therapies. FES Devices to Prevent Muscle Atrophy and Bone Demineralization A variety of devices use electrical ...

The Upper Cretaceous (middle-late Campanian) Wahweap Formation of southern Utah contains the oldest diagnostic evidence of ceratopsids (to date, all centrosaurines) in North America, with a number of specimens recovered from throughout a unit that spans between 81 and 77 Ma. Only a single specimen has been formally named, Diabloceratops eatoni, from the lower middle member of the formation. Machairoceratops cronusi gen. et sp. nov., a new centrosaurine ceratopsid from the upper member of the Wahweap Formation, is here described based on cranial material representing a single individual recovered from a calcareous mudstone. The specimen consists of two curved and elongate orbital horncores, a left jugal, a nearly complete, slightly deformed braincase, the left squamosal, and a mostly complete parietal ornamented by posteriorly projected, anterodorsally curved, elongate spikes on either side of a midline embayment. The fan-shaped, stepped-squamosal is diagnostic of Centrosaurinae, however, this ...
Late Cretaceous carbon isotope curves generated for localities in Europe, Asia, and the deep-sea records have provided the foundation for development of a contiguous, intercontinental chemostratigraphic framework. Despite the development of carbon isotope records from selected stratigraphic intervals in the Western Interior Basin, however, a comprehensive δ13C record comparable to those developed in Europe and Asia, and from ODP sites, had not yet been completed. This study reports a new, high-resolution Cenomanian to Campanian carbon isotope record for the central Western Interior Basin of North America that makes a key contribution to the intercontinental correlation. The curve is correlated to the well-developed molluscan biostratigraphic framework for the Western Interior Basin, as well as a revised geochronology based on integration of new radioisotopic dating and astrochronology developed in the same core records from where the δ13C data were derived. The new δ13C record reflects not ...
Common names for genera can be pluralized in English, although common names are not recommended (see above). Proper pluralization must be adding the s onto the end of the common name (tyrannosaurs), never the full name (tyrannosauruses). There is, however, no way to pluralize the scientific Latin names of taxa in any English way. The Latin name Tyrannosaurus is already both singular and plural, such as with "Moose". Thus, it would be proper to write both "There was a group of Tyrannosaurus" as well as "A single Tyrannosaurus". The same follows when using binomials instead of genera "A group of Tyrannosaurus rex". The only other proper form of pluralization is to replace the end of the name with -i, as in "Stegosauri". However, this refers to a group of multiple species and individuals of the genus, such that "A group of Stegosaurus stenops and armatus" would be the same as saying "A group of Stegosauri". This cannot work with binomials. Dont use binomials unless you want to imply that the ...
Tyrannosaurus rex is causing trouble again. Only this time, as tonight's offering from Nova explains, it is not as predator but as the object of conflicting affections. Curse of T.

Skirmishing began in 1990 when commercial fossil hunters unearthed a remarkably preserved dinosaur, courteously named Sue for its discoverer, on a ranch on a Sioux reservation in South Dakota.

For me, this is the dumbest argument. Its been demonstrated multiple times that Tyrannosaurus rex and its immediate relatives had ridiculous, astronomical bite forces and that their teeth and jaws were specialized for crushing bone. I imagine that their teeth were modified to allow such an activity. There are at least three instances in the fossil record of a tyrannosaur tearing through bone in the pusuit of food: an Edmontosaurus tail with several neural spines lobbed off, a Triceratops pelvis with several deep scraping tooth marks in it, and a Triceratops skull with a bitten-off horn core (Happ, this book). While the Triceratops pelvis may have been so marred by scavenging activity, the Edmontosaurus lived another day, and the bones healed. Thus, it escaped its pursuer. And one can only imagine that T.rex did not pick its teeth with the orbital horn cores of dead ceratopsians, so that particular exchange probably took place during either an attack by the tyrannosaur or an attack by the ...
