havior of elastic property. Previous studies on muscle pathology found that quantification of the shear modulus could be used as a clinical protocol to identify pathological muscles and to follow-up effects of treatments and therapies. These data could also be used for modelling purposes.
Anti-DFS70 antibodies are the most frequent antinuclear antibodies (ANA) found in healthy individuals. We assessed the clinical significance of the presence of anti-DFS70 antibodies.

We defined a group of patients (n = 421) with anti-DFS70 antibodies and a group of patients (n = 63) with a history of idiopathic arterial and/or venous thrombotic disease and/or obstetric complication (i.e. ≥ 3 miscarriages, fetal death or premature birth with eclampsia). Anti-DFS70 antibodies prevalence was also assessed in a cohort of 300 healthy blood donors.

The prevalence of thrombotic disease and/or obstetric complication in the 421 patients with anti-DFS70 antibodies was 13.1% (n = 55) and the prevalence of connective tissue disease was 19% (n = 80). Among the 63 patients with a history of thrombosis and/or obstetric complications, 7 (11.1%) had anti-DFS70 antibodies and among the latter, 5 had no common thrombophilic factor. In contrast, the prevalence of anti-DFS70 antibodies was of 3.0% (9 out of 300) in healthy donors. Finally, the Activated Partial Thromboplastin Time (aPTT) ratio of patients with a history of thrombosis and anti-DFS70 antibodies was lower than the aPTT ratio of other patients, suggesting that thrombotic patients with anti-DFS70 antibodies may have a hypercoagulable state.

We described here for the first time an immune procoagulant state involving anti-DFS70 antibodies.

Many CTC isolation technologies have been developed. We optimized the Parsortix system, an epitope independent, size and compressibility-based platform for CTCs isolation, making it possible to harvest CTCs at the speed and sample volume comparable to standard CellSearch system. We captured more than half of cancer cells from different cancer cell lines spiked in blood samples from healthy donors using this system. Cell loss during immunostaining of cells transferred and fixed on the slides is a major problem for analyzing rare cell samples. We developed a novel cell transfer and fixation method to retain >90% of cells on the slide after the immunofluorescence process without affecting signal strength and specificity. Using this optimized method, we evaluated the ParsortK-positive/Vimentin-positive/CD45-negative, and CK-negative/Vimentin-positive/CD45-negative cells were also observed in four of five prostate cancer patients but rarely in three healthy controls, indicating that Parsortix harvests CTCs with both epithelial and mesenchymal features. We also demonstrated using PC3 and DU145 spiking experiment that Parsortix harvested cells were viable for cell culture.Multiple stressors threaten stream physical and biological quality, including elevated nutrients and other contaminants, riparian and in-stream habitat degradation and altered natural flow regime. Unconventional oil and gas (UOG) development is one emerging stressor that spans the U.S. UOG development could alter stream sedimentation, riparian extent and composition, in-stream flow, and water quality. We developed indices to describe the watershed sensitivity and exposure to natural and anthropogenic disturbances and computed a vulnerability index from these two scores across stream catchments in six productive shale plays. We predicted that catchment vulnerability scores would vary across plays due to climatic, geologic and anthropogenic differences. Across-shale averages supported this prediction revealing differences in catchment sensitivity, exposure, and vulnerability scores that resulted from different natural and anthropogenic environmental conditions. For example, semi-arid Western shale play catchments (Mowry, Hilliard, and Bakken) tended to be more sensitive to stressors due to low annual average precipitation and extensive grassland. Catchments in the Barnett and Marcellus-Utica were naturally sensitive from more erosive soils and steeper catchment slopes, but these catchments also experienced areas with greater UOG densities and urbanization. Our analysis suggested Fayetteville and Barnett catchments were vulnerable due to existing anthropogenic exposure. BTK inhibitor However, all shale plays had catchments that spanned a wide vulnerability gradient. Our results identify vulnerable catchments that can help prioritize stream protection and monitoring efforts. Resource managers can also use these findings to guide local development activities to help reduce possible environmental effects.
Effective use of prophylactic antibiotics decreases the incidence of surgical site infections (SSIs) after total joint arthroplasty (TJA). The purpose of this prospective study was to determine the viability of weight-based dosing protocols for cefazolin and vancomycin to determine if appropriate minimum inhibitory concentrations (MIC) are met.

Trabecular bone was harvested from discarded bone samples from 34 patients undergoing total knee arthroplasty (TKA) and total hip arthroplasty (THA). The cefazolin and vancomycin concentrations were determined in the trabecular bone using high-performance liquid chromatography.

No difference was noted in bone concentration with respect to patient weight for cefazolin. Regarding vancomycin, a substantial difference was noted in trabecular bone concentrations with respect to patient weight with lower body mass index (BMI) achieving greater concentrations. Using the current weight-based protocol of antibiotic prophylaxis, 84% and 87% of patients receiving vancomycinrequired to determine if increasing the pre-operative dosage of antibiotics is mandated given the findings of this pilot study.We here report an experimentally verified binding mode for the known tripeptidomimetic CXCR4 antagonist KRH-1636 (1). A limited SAR study based on the three functionalities of 1 was first conducted, followed by site-directed mutagenesis studies. The receptor mapping showed that both the potency and affinity of 1 were dependent on the transmembrane residues His(113), Asp(171), Asp(262), and His(281) and also suggested the involvement of Tyr(45) and Gln(200) (potency) and Tyr(116) and Glu(288) (affinity). Molecular docking of 1 to an X-ray structure of CXCR4 showed that the l-Arg guanidino group of 1 forms polar interactions with His(113) and Asp(171) and the (pyridin-2-ylmethyl)amino moiety is anchored by Asp(262) and His(281), whereas the naphthalene ring is tightly packed in a hydrophobic subpocket formed by the aromatic side chains of Trp(94), Tyr(45), and Tyr(116). The detailed picture of ligand-receptor interactions provided here will assist in structure-based design and further development of small-molecule peptidomimetic CXCR4 antagonists.
To determine the reliability and reproducibility of peripheral nerve diffusion tensor imaging (DTI) in healthy subjects.

We assessed the test-retest and interrater reliability studies of peripheral nerve DTI in a cohort of 12 healthy subjects (mean age 44.0 years, range 26-71 years). Magnetic resonance imaging (MRI) studies were performed on a 3T scanner (MR750, GE Healthcare). DTI and T1 -weighted sequences were performed on the tibial and peroneal nerves in the knee. Each subject was scanned on three separate occasions. Image analyses were performed at two anatomic positions the level of the lateral femoral condyle (position 1), and the superior pole of the patella (position 2). Analysis was performed using three software packages ("raters") FuncTools, FSL, and Diffusion Toolkit. Metrics obtained included fractional anisotropy (FA), axial diffusivity (AD), and radial diffusivity (RD).

DTI metrics were not significantly different between each measurement position, except peroneal nerve AD and tibial nerve RD were higher at position 1 (P = 0.02 and 0.04, respectively). There was no significant difference in DTI metrics between male and female subjects (P = 0.10-0.99). The test-retest reliability of DTI metrics was high, maximal for FA (intraclass correlation coefficient [ICC] = 0.96). ICC values for individual DTI metrics were similar between each measurement position, except that tibial nerve AD was significantly higher at position 2 (P = 0.03). Interrater reliability was also high (ICC = 0.95-0.96).

We found peripheral nerve DTI to be reliable and reproducible, with few effects related to the postprocessing package used.

The aim of the present study was to evaluate the influence of oral conditions in preschool children and associated factors on work absenteeism experienced by parents or guardians.

A preschool-based, cross-sectional study was conducted of 837 children, 3-5 years of age, in Campina Grande, Brazil. Parents or guardians answered the Brazilian version of the Early Childhood Oral Health Impact Scale. The item 'taken time off work' was the dependent variable. Questionnaires addressing sociodemographic variables, history of toothache and health perceptions (general and oral) were also administered. Clinical examinations for dental caries and traumatic dental injury (TDI) were performed by three dentists who had undergone training and calibration exercises. Cohen's kappa (κ) was 0.83-0.88 for interexaminer agreement and 0.85-0.90 for intra-examiner agreement. Descriptive, analytical statistics were conducted, followed by logistic regression for complex samples (α = 5%).

The prevalence of parents' or guardians' wion, luxation and a low degree of mother's schooling are associated with work absenteeism.Evidence-based treatments for posttraumatic stress disorder (PTSD) can reduce symptoms and improve veterans' psychological health. Unfortunately, many veterans leave treatment before receiving maximum benefit. Fear of emotions is related to severity of PTSD, and changes in fear of emotions are correlated with changes in PTSD symptoms. This study built upon the literature linking greater fear of emotions to PTSD severity by examining whether pretreatment fear of emotions, measured by the Affect Control Scale, was associated with completion of cognitive processing therapy (CPT) and severity of posttreatment PTSD in a sample of 89 U.S. veterans who had served in Afghanistan and Iraq. About 60% of veterans completed 10 or more therapy sessions. A logistic regression on 51 of the 89 subjects that more fear of anxiety at pretreatment was associated with decreased likelihood of completing treatment, OR = 0.93, 95% CI [0.87, 1.00]. Of those veterans who completed treatment, higher fear of anger at pretreatment was negatively related to severity of PTSD posttreatment (β = -.29, p = .037), in a model with the other predictors. Assessing veterans for fear of anxiety and anger before CPT and teaching emotion regulation skills to those in need may reduce treatment dropout.
