P28 ARE PERIODONTAL ENDPOINTS PREDICTIVE OF THE FRAX SCORE IN POSTMENOPAUSAL WOMEN AND VICE VERSA Foluke M. Alli, MD, Cleveland Clinic, Cleveland, OH; Gazabpreet K. Bhandal, DDS, Case

Western Reserve University, Cleveland, OH; Leena Bahl-Palomo, DDS, MSD, Case Western Reserve University, Cleveland, OH; Holly L. Thacker, MD, Cleveland Clinic, Cleveland, OH BACKGROUND: The FRAX score has been used to calculate the risk of fracture in postmenopausal women 50 years or older with low bone mineral density to identify patients at highest risk for fracture who will require treatment. Both periodontitis and osteoporosis constitute significant health problems especially in postmenopausal women. It is thought that these are related as they both affect the bone and many of the same factors which increase risk for osteoporotic fracture are also risk for periodontitis. selleck products As such are these periodontal end points also a predictor? Number of teeth lost, clinical attachment loss, gingival bleeding? AIM: To determine if periodontal endpoints are predictive of the FRAX score in postmenopausal women and vice versa. METHOD: This is a cross-sectional study using participants

in the NHANES data Ureohydrolase set that have periodontal data recorded. Data was obtained on 4207 postmenopausal women who participated in the survey and used to calculate the FRAX score. This was then compared against various periodontal end points such as number of teeth lost, clinical attachment loss and gingival bleeding. RESULT: Increased age was associated with increased osteoporotic fracture risk P < 0.001. As BMI increased, osteoporotic fracture risk decreased P < 0.001. Patients with higher FRAX scores lost more teeth and had larger (free gingival margin) FGM to cement enamel junction (CEJ) measurements

as well as FGM to sulcus base measurements. P < 0.001. Univariable analysis showed that patients that experienced tooth loss tend to be older and have higher FRAX scores. Tooth loss was not associated with BMI P 0.84. This pattern held true for mid- facial loss of attachment and meso-facial loss of attachment. Median attachment loss measurements were higher as FRAX scores increased. But after controlling for age and BMI, FRAX scores were not associated with an increased risk in attachment loss. CONCLUSION: If periodontal end points such as number of teeth lost correlates with FRAX scores, dental professionals are in a position to refer women to women’s health clinics for fracture risk assessment, counseling and prevention and women’s health centers should be referring patients with increased FRAX scores for dental interventions.

These ESTs were assembled in 296 contigs and 1092 singletons, resulting in 1388 unique sequences with a redundancy of 49.3% (Table 1). The majority of the contigs assembled ESTs from a maximum of four libraries, suggesting that these genes are expressed under environmental stress or specific growth conditions. The search results and GenBank submission numbers for each EST are shown in Additional file 1. Analysis of these 1388 unigenes revealed 666 sequences that had no similarity to the sequences in the GenBank dbEST, which contains 37890 T. rubrum sequences. Of the 666 sequences, 404 had no similarities to the sequences

in the nonredundant database (Table 1). Additional analysis revealed that of the 666 sequences, 91 were present STI571 in the TrED database [16]. Thus, 575 novel genes were identified, representing a marked increase in the number of expressed genes Epigenetic Reader Domain inhibitor identified in the dermatophyte T. rubrum.

mimicus strains, we compared the cytotoxicity of the wild-type and mutant strains for cultured cell lines. T3SS-deficient mutants were constructed by disruption of the homologue of the vscN2 gene, which encodes an ATPase of

T3SS2, in V. mimicus RIMD2218042 (α type) and RIMD2218067 (β type) strains. To confirm the deletion of the vscN2 gene, PCR amplification using oligonucleotide primer pairs was performed (see Additional file 1 and 8). The growth of the mutant strains MX69 in LB medium (1% NaCl) was indistinguishable from that of the parental strains (data not shown). Both V. mimicus RIMD2218042 and RIMD2218067 strains were cytotoxic for Caco-2 cells at 3 h post-infection. The cytotoxicity of both the T3SS2α- and T3SS2β-deficient mutant strains tended to decrease, but there were no significant differences between T3SS2α- and T3SS2β-deficient mutant strains and their parental strains (see Additional file 9). Discussion A recent study of ours demonstrated that two lines of distinct lineage of the T3SS2 gene cluster, T3SS2α and T3SS2β, are ARS-1620 purchase present in the KP-positive and trh-positive V. parahaemolyticus strains, respectively C59 purchase [20]. Although a previously reported study using dot blot

analysis could not detect the genes for T3SS2 in 16 Vibrio species, the probes and PCR primers used in previous studies were designed based on the sequence information of the T3SS2α genes in V. parahaemolyticus strain RIMD2210633 [7, 14]. Since the T3SS2β genes cannot be detected by either PCR amplifications or comparative genomic hybridization analysis targeting the T3SS2α genes [7, 15], we re-investigated the distribution of the T3SS2 genes, both T3SS2α and T3SS2β, in Vibrio species. To examine the distribution of the genes for T3SS2 in vibrios other than V. parahaemolyticus, we performed a PCR assay using PCR primer pairs targeting both the T3SS2α and T3SS2β genes. Of the 32 Vibrio species tested, the T3SS2-related genes were detected in three species, V. cholerae, which was previously reported, as well as V. hollisae and V. mimicus. In V. hollisae strains, only three genes for T3SS2α, Lepirudin vscN2, vscR2, and vscT2, were detected. Nevertheless,

the fact that the PCR reactions for these three genes were positive in all the five V. hollisae strains tested is intriguing. We speculate that the other genes for T3SS2α might be absent in these particular V. hollisae strains, or that the sequences of the other genes included variations that would make PCR amplification with the primer pairs used in this assay difficult. These possibilities should be examined in the future by more detailed genetic analyses, e.g. sequencing of the region flanking the T3SS2-related genes. A previous study showed that the T3SS2-related genes are present in V. mimicus strains [25]. In our study, the PCR assay also demonstrated the presence of the T3SS2 genes in V. mimicus strains. Of the 15 V.

nanostructure was capped with check details a clear spherical particle. EDX analyses of the particle and stem showed that this particle was composed mainly of Sn (69.4 at.%) and considerably small amounts of In (2.5 at.%) and O (28.1 at.%). Moreover, the stem of the nanostructure consisted mainly of In (44.4 at.%) and O (53.6 at.%) and a small amount of Sn (2.0 at.%). The analyses of the composition revealed that the O content of the stem was below the stoichiometric value of In2O3, which is consistent with the XPS O 1 s analysis. The presence of Sn-rich particles at the ends of the nanostructures indicated that the vapor–liquid-solid (VLS) process might be

crucial for crystal growth. Several studies on the synthesis of In2O3 nanostructures have shown the importance of the Au catalytic layer for the formation of In2O3 nanostructures [23]. Most of the catalytic JNJ-26481585 manufacturer growth of oxide nanostructures through vapor transport follows a VLS crystal growth process [24]. In this work, no metallic thin layer was pre-deposited onto the substrates to act as a catalyst for nanostructure growth. Recently, a self-catalyst VLS growth mechanism see more was proposed to explain the growth of Mg-doped ZnO nanostructures

and Zn-Sn-O nanowires [25, 26]. The origin of the metallic Sn particles at the ends of our nanostructures might thus be similar to those of previously reported nanostructures. The selected TEM image taken from the corner of the particle-stem Bcl-w region of Figure 6b reveals a non-zero conical angle, demonstrating that the nanostructure geometry ended at a decreasing radius during growth (inset 1 in Figure 6b). The HRTEM image in Figure 6b shows clear lattice fringes corresponding to the (200) plane, which is perpendicular to the stem axis, of the cubic In2O3 structure. The sharp and bright spots in the selected area electron diffraction (SAED) pattern taken along the [001] zone axis show that the nanostructure was single crystalline and grew along the [100] axis (inset 3). Moreover, the SAED pattern of the particle could be indexed along the [010] zone axis of Sn (inset 4). The HRTEM image taken from the interface of particle and stem reveals a thin transition layer with a thickness of approximately 5 nm at the interface (inset 5). Below this transition layer, ordered lattice fringes of (200) for In2O3 were observed over the entire stem.

In this investigation, it is experimentally confirmed that interfacial compressive stress in nanoscale can induce the martensitic transformation in FeNi nanolayers. Generally, within the nanostructured materials, a large Emricasan amount of interfacial stress could exist owing to the high volume fraction of interfaces, which might modulate the martensitic transformation of the nanostructured

materials and make the martensitic transformation behaviors in the nanostructured materials differ from their conventional coarse-grained eFT508 cost counterparts. Utilizing the nanomultilayered structure, the interfacial compressive or tensile stress can be imposed on the different nanofilms and the influence of the interfacial compressive or tensile stress on the martensitic transformation

and even other phase transformations of nanofilms can be experimentally investigated. Therefore, the method of imposing and modulating the interfacial stress through the epitaxial growth structure in the nanomultilayered films should also be noticed and utilized. Conclusions In summary, FeNi/V nanomultilayered films with different V layer thicknesses were synthesized by magnetron sputtering. By adjusting the thickness of the V layer, different interfacial compressive stress were imposed on FeNi layers and the effect of interfacial stress on martensitic transformation in the FeNi film was investigated. Without insertion of V layers, the FeNi film exhibits a fcc structure. With the thickness of V inserted layers up to 1.5 nm, under Arachidonate 15-lipoxygenase the coherent growth structure in FeNi/V nanomultilayered films, FeNi layers bear interfacial compressive stress due to the larger lattice parameter relative to V, which induces the MEK inhibitor martensitic transformation of the FeNi film. As the V layer thickness increases to 2.0 nm, V layers cannot keep the coherent growth structure with FeNi layers, leading to the disappearance of interfacial stress and termination of the martensitic transformation in FeNi films. This investigation verifies that the martensitic transformation

could be induced by the nanoscaled interfacial stress in the FeNi nanofilms. The method of imposing and modulating the interfacial stress through the epitaxial growth structure in the nanomultilayered films should also be especially noticed and utilized.

All these secreted proteins regulate cell adhesion [7, 8] The ex

All these secreted proteins regulate cell adhesion [7, 8]. The extracellular domain of POSTN is evolutionarily conserved from humans to bacteria [9]. POSTN was first identified in MC3T3-E1 osteoblast-like cells [8], and it was preferentially expressed in periosteum in vivo [10]. The overexpression of a basic helix–loop–helix transcription

factor, Twist, is related to the increased expression of POSTN by binding to its promoter in preosteoblasts [11]. Twist plays a key regulatory role in early osteogenesis [12]. Inactivation of POSTN leads to a severe reduction of osteoblast-specific differentiation markers, such as type I collagen, osteocalcin, osteopontin, and alkaline phosphatase [13]. Recently, an animal study demonstrated that the Postn protein is essential for the down-regulation of sclerostin (Sost) and thereby plays an important role in the determination of bone mass and microstructural in response to loading [14]. SOST is important in bone see more and mineral metabolism, and its polymorphisms have previously been shown to associate with BMD [15]. These functional reports propose a role for POSTN in this website human osteoblast

differentiation and bone formation. This prompted us to perform a genetic association study EGFR inhibitor between SNPs along the POSTN gene and osteoporosis phenotypes. We first selected the tag SNPs (tSNPs) of the POSTN gene and studied their relationship with BMD variation in a Hong Kong Southern Chinese (HKSC) population that included 1,572 subjects with extreme BMD. We then used the imputation approach to study the phenotypic associations with a more extensive fine map of polymorphisms around the gene region using the Asian population data of HapMap phase II as the reference. The significant association was further confirmed in another independent Hong Kong Osteoporosis Study (HKOS) prospective cohort with BMD (n = 2,509)

and vertebral fracture (n = 1,746) data. In addition, the finding from animal study may suggest the interactive effect between POSTN and SOST genes on regulating of BMD; thus, the interaction analysis was also conducted between these two genes in this study. Finally, the potentially biological function of the identified variant of POSTN gene was studied. Telomerase Methods Subjects HKSC cohort with extreme BMD A total of 1,572 unrelated subjects (81.3% women) with either high or low BMD were selected from a growing database at the Osteoporosis Centre of the University of Hong Kong (>9,000 HKSC volunteers). Subjects that were reported to have diseases or environmental factors that may affect BMD and bone metabolism were excluded. The recruitment procedure and exclusion criteria have been detailed elsewhere [16]. BMD was measured at the lumbar spine (LS) and femoral neck (FN) by dual X-ray absorptiometry (Hologic QDR4500, Waltham, MA, USA). The in vivo precision of the machine was 1.2% and 1.5% for LS and FN BMD, respectively.
