TY - GEN. T1 - Pecvd SiOx accelerates hydroxyapatite surface formation for enhanced early osteogenic differentiation. AU - Velten, M. F.. AU - Odatsu, T.. AU - Aswath, P. B.. AU - Kamiya, N.. AU - Kim, H.. AU - Varanasi, V. G.. PY - 2014/1/1. Y1 - 2014/1/1. N2 - Current metal implants are designed to structurally support the surrounding bone upon fracture. However, they have long healing times as they do not form an apatite surface layer for direct bone bonding and do not enhance osteogenesis. In this study, we use amorphous silica (SiOx) nanolayers as a potential implant coating material to improve bone healing. The aim of this study is to determine the ability of SiOx nanolayers to enhance osteogenic differentiation via rapid surface hydroxyapatite (HA) formation. SiOx nanolayers are prepared using plasma enhanced chemical vapor deposition. These nanolayers are also etched with grooves to facilitate osteoprogenitor attachment. Immersion of these nanolayers in-vitro showed a decrease in the ...
Protein kinase C in the developing rat brain was investigated by a biochemical assay and by light-microscopic immunocytochemistry. The protein kinase was resolved on hydroxyapatite column chromatography into 3 fractions, designated types I, II, and III. Type I, with structure encoded by a gamma-sequence, was not detected early postnatally, maintained a low level of activity during the first week, which increased gradually, and reached its maximum around postnatal day 28. This type of enzyme was expressed specifically in nervous tissues, and was not found in any other tissues thus far tested. Type II enzyme activity, a mixture of the 2 subspecies encoded by the beta I- and beta II-sequences, was found at birth, increased rapidly, and reached a plateau level between postnatal days 14 and 28. This type was the predominant subspecies of protein kinase C in the brain. Type III, its structure encoded by the alpha-sequence, was also detected at birth, and reached its maximum level on postnatal day 7. ...

1. Monoamine oxidase from rat and human liver was purified to homogeneity by the criterion of polyacrylamide-gel electrophoresis in the presence of sodium dodecyl sulphate. 2. The enzyme activity was extracted from mitochondrial preparations by Triton X-100. The enzyme was purified by (NH4)2SO4 fractionation followed by chromatography on DEAE-cellulose, Sepharose 6B, spheroidal hydroxyapatite, and finally chromatography on diazo-coupled tyramine-Sepharose. 3. Distinct differences occur in the chromatographic behaviour of the two enzymes on both DEAE-cellulose and spheroidal hydroxyapatite. 4. It is unlikely that the purification of the enzymes on tyramine-Sepharose is due to affinity chromatography and reasons for this are discussed. 5. The purified enzymes did not oxidize-5-hydroxytryptamine and the relative activities of the enzymes with benzylamine were increased approx. 1.25-fold compared with the enzyme activities of mitochondrial preparations. 6. Immunotitration of enzyme activity in ...

INJECTION FOR LIPS AND SMILE LINES BEATS HYALURONIC ACID. Radiesse® is a new injectable product for lip enlargement and filing of folds and lines of the skin of the face. The advantage of this product is its potential for a long lasting effect, perhaps several years or longer.. Radiesse® consists of calcium hydroxyapatite suspended in a gel of carboxymethylcellulose. Because calcium hydroxyapatite is a normal constituent of bone, it does not elicit a chronic inflammatory or immune response. For this reason, it is unnecessary to undergo skin testing, as required with collagen.. Calcium hydroxyapatite has been used in humans for a long time in prosthetic implants in dental, facial and orthopedic surgery. Injection of Radiesse® into the vocal cords and the bladder neck has shown that the product remains soft when injected into soft tissue and may last for years.

Ethanol is currently the most common liquid fuel derived from biomass in the world, used primarily as a blendstock in gasoline-powered vehicles. In the next 20 years, demand is anticipated to grow in heavier, C8-22 distillate-range fuels such as diesel and jet while that of gasoline is projected to decrease,1 motivating research efforts into the conversion ethanol to heavier fuels.2 Coupling of ethanol via the Guerbet pathway has been examined mainly as a means to produce 1-butanol, which has improved gasoline fuel properties compared to ethanol.3-4 Ethanol coupling beyond 1-butanol is possible, resulting in both linear and branched C6+ alcohols.5-6 The potential of using alcohol coupling to produce distillate-range alcohols from ethanol is largely unknown since coupling beyond 1-butanol is seldom-studied and complicated by several complexities which arise at elevated conversions (,30%). Here we discuss the use of kinetic modeling to understand how inhibition by byproduct water and differences ...

Neauvia Organic Hydro Deluxe Man contains 18 mg/ml of pure hyaluronic acid derived from Bacillus subtilis. Such high concentration allows to obtain very good results noticeable from the first treatment. In addition, Neauvia Organic Hydro Deluxe Man is enriched with 0,01% of calcium hydroxyapatite and two amino acids. In addition to hyaluronic acid it contains amino acids - Glycine and L-Proline - that are main ingredients of collagen. This unique composition activates and supports natural processes of collagen production, thanks to which skin becomes thicker and firmer.. A series of 4 treatments with 3 week intervals between all treatments should be performed to achieve optimal results. At the end of the series, in order to maintain results, it is worth offering to a patient a follow-up treatment scheduled for half a year later. ...
Pyrimidine- and purine-rich strands of Mus musculus satellite DNA prepared by alkaline CsCl-gradient centrifugation can self-renature to a variable extent to give partial duplexes with high thermal stability. These duplexes were purified by treatment with nuclease S1 followed by hydroxylapatite chromatography, and have been shown by pyrimidine-tract analysis to be very similar in sequence to total reassociated satellite DNA. It is believed that the self-renaturing fractions result from variable contamination of each strand with fragments of the other, rather than from molecular inversions. The predominantly single-stranded properties of these fractions may be partly due to the ability of mouse satellite DNA strands to reassociate in non-stoicheiometric proportions.. ...

It is observed that good strength results are obtained by the compression to low pressures, what can suggest us that we are in the pressures frontier that causes overpressing in the material after the sintering process.. The proposed polynomial was: Y = b0 + b1X1 + b2X2 + b3X3 + b12X1X2 + b13X1X3 + b23X2X3 + b123X1X2X 3 + b33X32 + b133X1X3 2 + b233X2X3 2. For DTS we thought about quadratic terms of temperature, only variable with three levels, what presupposes their importance in the analysis. The resulting polynomial DTS = 7.2575 - 1.86 p + 6.03375 T + 5.68125 T2 shows the temperature influence, because the linear and quadratic terms are significant to the statistical analysis. Besides, a small inverse influence of the pressure is observed. A slight increment of the DTS exists as the pressure value decreases. The biggest values of DTS were obtained at 1200oC.. For density, the resulting polynomial was r = 1.47375 + 0.2965 T - 0.245 T2 + 0.0655 PT + 0.01625 hT2 - 0.09125 PT2, where the ...

Crude extracts of Mycobacterium smegmatis catalyzed the synthesis of adenosine diphosphate-glucose (ADP-Glc), cytidine diphosphate-glucose, guanosine diphosphate-glucose (GDP-Glc), thymidine diphosphate-glucose (TDP-Glc), and uridine diphosphate-glucose (UDP-Glc). In these crude enzyme fractions, high concentrations of trehalose-P inhibited the ADP-Glc and GDP-Glc pyrophosphorylases but did not effect the UDP-Glc or TDP-Glc pyrophosphorylases. Both the ADP-Glc pyrophosphorylase and the UDP-Glc pyrophosphorylase were partially purified (about 140-fold and 60-fold, respectively), and their properties were compared. For the ADP-Glc pyrophosphorylase, the Km for adenosine triphosphate was 6 × 10−4m, whereas that for glucose-1-P was 8 × 10−4m. The optimal concentration of Mg2+ was 1 × 10−3m, and the pH optimum was 8.5. For the UDP-Glc pyrophosphorylase, the Km for uridine triphosphate was 1 × 10−3m and for glucose-1-P was 2 × 10−3m. The optimal Mg2+ concentration was 1 × 10−3m, and ...
This study examined the initial attachment of Streptococcus sanguis G9-B and Actinomyces viscosus T14V to saliva-treated powdered enamel and titanium surfaces. Using an in vitro adherence model, significantly lower numbers of Actinomyces viscosus T14V bound to the saliva-treated titanium surface when compared to that of the similarly treated enamel. The binding of Streptococcus sanguis G9-B to titanium or enamel did not vary significantly. A comparison of the percentage of cells bound to the titanium surface revealed that S sanguis cells attached in significantly higher numbers when compared to the A viscosus cells ...
