Blood Pressure and Heart Rate Variability and the Impact on Pregnancy Outcomes: A Systematic Review.

Background: Long-term (visit-to-visit) blood pressure variability (BPV) and heart rate variability (HRV) outside pregnancy are associated with adverse cardiovascular outcomes. Given the limitations of relying solely on blood pressure level to identify pregnancies at risk, long-term (visit-to-visit) BPV or HRV may provide additional diagnostic/prognostic counsel. To address this, we conducted a systematic review to examine the association between long-term BPV and HRV in pregnancy and adverse maternal and perinatal outcomes.

Prosthetic management of an ocular defect utilizing a novel threaded iris fabrication technique.

Unlabelled: The conservative prosthodontic construction of an ocular prosthesis utilizing our novel threaded iris fabrication technique required high time and prosthodontic resource inputs and produced a lifelike aesthetic result.

Abstract: Patients with ocular defects frequently present with significant local anatomical deficiencies and complex histories and require extensive time and resource inputs to treat. This case report describes the conservative management of an ocular defect completed in a postgraduate prosthodontics clinical residency program utilizing a novel threaded iris fabrication technique.

Institutional Variation in 30-Day Complications Following Catheter Ablation of Atrial Fibrillation.

Background Complications are a measure of procedural quality, yet variation in complication rates following catheter ablation of atrial fibrillation (AF) among hospitals has not been systematically examined. We examined institutional variation in the risk-standardized 30-day complication rates (RSCRs) following AF ablation which may suggest variation in care quality. Methods and Results This cohort study included all patients >18 years old undergoing AF ablations from 2012 to 2017 in Australia and New Zealand.

Spatial-confinement induced electroreduction of CO and CO to diols on densely-arrayed Cu nanopyramids.

The electroreduction of carbon dioxide (CO) and carbon monoxide (CO) to liquid alcohol is of significant research interest. This is because of a high mass-energy density, readiness for transportation and established utilization infrastructure. Current success is mainly around monohydric alcohols, such as methanol and ethanol.

Density-functional tight-binding for phosphine-stabilized nanoscale gold clusters.

We report a parameterization of the second-order density-functional tight-binding (DFTB2) method for the quantum chemical simulation of phosphine-ligated nanoscale gold clusters, metalloids, and gold surfaces. Our parameterization extends the previously released DFTB2 "auorg" parameter set by connecting it to the electronic parameter of phosphorus in the "mio" parameter set. Although this connection could technically simply be accomplished by creating only the required additional Au-P repulsive potential, we found that the Au 6p and P 3d virtual atomic orbital energy levels exert a strong influence on the overall performance of the combined parameter set.

Mechanistic insight into the non-hydrolytic sol-gel process of tellurite glass films to attain a high transmission.

The development of amorphous films with a wide transmission window and high refractive index is of growing significance due to the strong demand of integrating functional nanoparticles for the next-generation hybrid optoelectronic films. High-index TeO-based glass films made the sol-gel process are particularly suitable as their low temperature preparation process promises high compatibility with a large variety of nanoparticles and substrates that suffer from low thermal stability. However, due to the lack of in-depth understanding of the mechanisms of the formation of undesired metallic-Te (highly absorbing species) in the films, the preparation of high-transmission TeO-based sol-gel films has been severely hampered.

Isolation and identification of Enterococcus faecalis membrane proteins using membrane shaving, 1D SDS/PAGE, and mass spectrometry.

Enterococcus faecalis is a significant nosocomial pathogen, which is able to survive in diverse environments and resist killing with antimicrobial therapies. The expression of cell membrane proteins play an important role in how bacteria respond to environmental stress. As such, the capacity to identify and study membrane protein expression is critical to our understanding of how specific proteins influence bacterial survival.

Analysis of millimetre-wave polarization diverse multiple-input multiple-output capacity.

Millimetre-waves offer the possibility of wide bandwidth and consequently high data rate for wireless communications. For both uni- and dual-polarized systems, signals sent over a link may suffer severe degradation due to antenna misalignment. Orientation robustness may be enhanced by the use of mutual orthogonality in three dimensions.

Soluble amyloid precursor protein alpha reduces neuronal injury and improves functional outcome following diffuse traumatic brain injury in rats.

Amyloid precursor protein (APP) has previously been shown to increase following traumatic brain injury (TBI). Whereas a number of investigators assume that increased APP may lead to the production of neurotoxic Abeta and be deleterious to outcome, the soluble alpha form of APP (sAPPalpha) is a product of the non-amyloidogenic cleavage of amyloid precursor protein that has previously been shown in vitro to have many neuroprotective and neurotrophic functions. However, no study to date has addressed whether sAPPalpha may be neuroprotective in vivo.

X-Ray Structure and In Vitro Anti-Tumoural Activity of the Dimeric Bis[(2-Phenyl-1,2-Dicarba-Closo-Dodecaborane-1-Carboxylato)-Di-n-Butyltin] Oxide.

X-ray diffraction studies reveal the structure of {[(2-C(6)H(5)-1,2-C(2)B(10)H(10)-1-COO)Bu(2)Sn](2)O}(2), 1, to conform to the common motif found for {[(R'COO)R(2)Sn](2)O}(2) compounds. The dimer features a central Bu(2)Sn(2)O(2) unit (two-fold symmetry) with the two Bu(2)Sn groups being linked via bridging oxygen atoms, each of which also carries an exocyclic Bu(2)Sn moiety. The two pairs of exo- and endo-cyclic tin atoms are each linked via an almost symmetrically bridging carboxylate ligand and the two remaining ligands coordinate an exocyclic tin atom only, in the monodentate mode.
