The association between cannabis use and motivation and intentions to quit tobacco within a sample of Australian socioeconomically disadvantaged smokers.

This study aimed to (i) describe concurrent and simultaneous tobacco and cannabis use and (ii) investigate the association between cannabis use and motivation and intentions to quit tobacco in a sample of socioeconomically disadvantaged smokers. A cross-sectional survey was conducted in 2013 and 2014 with current tobacco smokers receiving aid from two community service organizations in New South Wales, Australia. At least weekly cannabis use for the month prior to survey, motivation to quit tobacco and intentions to quit tobacco were measured in 369 participants (77% consent rate). Regressions were carried out to investigate associations between weekly cannabis use and motivation and intentions to quit tobacco.Concurrent tobacco and cannabis use was reported by 19% (n = 71) of the sample and of these users, 100% reported simultaneous use. Although regular cannabis use was significantly associated with lower motivation to quit tobacco, it was not significantly associated with intentions to quit tobacco in the next 30 days. Concurrent cannabis use is common in disadvantaged smokers and may play a role in decreased motivation to quit tobacco; however, it does not appear to be associated with intentions to quit in a sample of disadvantaged smokers.
Development and characterization of in situ gelling system containing atorvastatin-loaded polycaprolactone nanoparticles for periodontal diseases

: The periodontal pocket provides a suitable environment for bacterial accumulation and growth which results in ultimately tooth loss. The clinical efficacy of current therapy for periodontal pocket is low because the flushing actions within the mouth causes to rapid clearance of the solution. The antioxidant and anti-inflammatory effects of atorvastatin (ATV) can facilitate healing process of periodontal diseases. The aim of this study was to develop in situ gel formulation containing ATV-loaded polycaprolactone nanoparticles (PCL-NPs). PCL NPs were prepared by nanoprecipitation method. The NPs had spherical shape with a particle size range of 176-329 nm. They showed 59% encapsulation efficiency and prolonged release profile. In order to increase the mucoadhesive properties of the formulation and the residence time of the drug at the site of action, NPs were incorporated to in situ gel to provide a combination therapy. In situ gel formulation was prepared by cold method and characterized in terms of pH, gelation temperature and time, viscosity, syringeability, and rheological behaviours. In vitro release studies revealed that in situ gel formulation remarkably extend the release time of ATV and mathematical release kinetic modelling shows formulations can fit multiple models. The overall findings indicated that the combination therapy strategy of locally administration of in situ gel containing ATV-loaded polycaprolactone nanoparticles to periodontal pockets is a promising and innovative approach.
Novel strong tracking square‐root cubature kalman filter for GNSS/INS integrated navigation system

In the GNSS/INS integrated navigation system, the accuracy of square-root cubature Kalman filter (SCKF) will be reduced when the process model is not precisely known. To solve this problem, a novel strong tracking SCKF is proposed. The proposed algorithm utilises the measurement update module based on singular value decomposition (SVD), which can reduce the computational complexity. Moreover, a novel method to obtain suboptimal fading factor based on the orthogonality of the innovation is deduced here, which is simple to calculate and no need to solve the Jacobian matrix. This novel method introduces the calculated suboptimal fading factor into the square-root of the state prediction covariance matrix. Then, the gain matrix can be adjusted online which can improve the robustness of the algorithm when the process model is uncertain. Meanwhile, the proposed algorithm adopts the hypothesis testing to detect the uncertainty of the process model. Then, the proposed approach will only use the suboptimal fading factor when the existing process model is uncertain. The results of both numerical simulations and the field tests with GNSS/INS integrated navigation system demonstrate the effectiveness of the proposed algorithm.

Structural proteomics : elucidating in vivo structural dynamics of integral membrane proteins by hydroxyl radical footprinting

ion of hydrogen from the α-carbons at main chains (5). Oxidation schemes and pathways vary among amino acid residues of different side chains, i.e., aliphatic side chains, basic side chains, acidic side chains, aromatic side chains and sulfur-containing side chains (5) and we won‘t discuss the detailed chemical mechanisms here. It has been reported that there are a number of types of side chain oxidation products in OH radical protein footprinting experiments, however, not all of these oxidation products are common events as reviewed (5, 11). In general, as to almost all the amino acids, the oxidation produces a hydroxyl group at their side chains and the formation of alcohol group as major products, resulting in +16 Da mass increases. As to amino acids with aliphatic side

Impact of atmospheric and terrestrial CO2 feedbacks on fertilization-induced marine carbon uptake

The sensitivity of oceanic CO2 uptake to alterations in the marine biological carbon pump, such as brought about by natural or purposeful ocean fertilization, has repeatedly been investigated by studies employing numerical biogeochemical ocean models. It is shown here that the results of such ocean-centered studies are very sensitive to the assumption made about the response of the carbon reservoirs on the atmospheric side of the sea surface. Assumptions made include prescribed atmospheric pCO2, an interactive atmospheric CO2 pool exchanging carbon with the ocean but not with the terrestrial biosphere, and an interactive atmosphere that exchanges carbon with both oceanic and terrestrial carbon pools. The impact of these assumptions on simulated annual to millennial oceanic carbon uptake is investigated for a hypothetical increase in the C:N ratio of the biological pump and for an idealized enhancement of phytoplankton growth. Compared to simulations with interactive atmosphere, using prescribed atmospheric pCO2 overestimates the sensitivity of the oceanic CO2 uptake to changes in the biological pump, by about 2%, 25%, 100%, and >500% on annual, decadal, centennial, and millennial timescales, respectively. The smaller efficiency of the oceanic carbon uptake under an interactive atmosphere is due to the back flux of CO2 that occurs when atmospheric CO2 is reduced. Adding an interactive terrestrial carbon pool to the atmosphere-ocean model system has a small effect on annual timescales, but increases the simulated fertilization-induced oceanic carbon uptake by about 4%, 50%, and 100% on decadal, centennial, and millennial timescales, respectively, for pCO2 sensitivities of the terrestrial carbon storage in the middle range of the C4MIP models (Friedlingstein et al., 2006). For such sensitivities, a substantial fraction of oceanic carbon uptake induced by natural or purposeful ocean fertilization originates, on timescales longer than decades, not from the atmosphere but from the terrestrial biosphere.

Quality of Life Assessment Before and After Laser in situ Keratomileusis

S tudies about the quality of life and its visual aspects have been done over the past ten years. Laser correction by photorefractive keratectomy (PRK) in patients with refractive errors has a long period of recovery to stable refraction of almost 3 months, although most patients have functional vision at 1-2 weeks postoperatively. Moreover, problems of night vision, glare and halo around the light may disturb their daily life. Quality of Life Assessment Before and After Laser in situ Keratomileusis
Human Bone Marrow-Derived Mesenchymal Stem Cells for Intravascular Delivery of Oncolytic Adenovirus Delta-24-RGD to Human Gliomas

Delta-24-RGD is an infectivity-augmented, conditionally-replicative oncolytic adenovirus with significant antiglioma effects. Although intratumoral delivery of Delta-24-RGD may be effective, intravascular delivery would improve successful application in humans. Due to their tumor tropic properties, we hypothesized that human mesenchymal stem cells (hMSCs) could be harnessed as intravascular delivery vehicles of Delta-24-RGD to human gliomas. To assess cellular events, GFPlabeled hMSCs carrying Delta-24-RGD (hMSCs-Delta24) were injected into the carotid artery of mice harboring orthotopic U87MG or U251-V121 xenografts and brain sections were analyzed by immunofluorescence for GFP and viral proteins (E1A and hexon) at increasing times. hMSCsDelta24 selectively localized to glioma xenografts and released Delta-24-RGD, which subsequently infected glioma cells. To determine efficacy, mice were implanted with luciferase-labeled glioma xenografts, treated with hMSCs-Delta24 or controls and imaged weekly by bioluminescence imaging (BLI). Analysis of tumor size by BLI demonstrated inhibition of glioma growth and eradication of tumors in hMSCs-Delta24-treated animals compared with controls (P<0.0001). There was an increase in median survival from 42 days in controls to 75.5 days in hMSC-Delta-24-treated animals (P<0.0001) and an increase in survival beyond 80 days from 0% to 37.5%, respectively. We conclude that intra-arterially delivered hMSCs-Delta24 selectively localize to human gliomas, and are capable of delivering and releasing Delta-24-RGD into the tumor, resulting in improved survival and tumor eradication in subsets of mice.

A 1D model study of brine dynamics in sea ice

In this thesis I develop a new 1D thermodynamic sea-ice model with parametrized brine dynamics to study brine movement inside sea ice and the evolution of sea-ice salinity. Brine dynamics, which have never been measured directly, are poorly understood and determine the evolution of sea-ice salinity which in turn influences the phase composition and thermodynamic properties of sea ice as well as the stratification of the ocean. The newly developed 1D Semi-adaptive Multi-phase Sea-Ice Model SAMSIM has many unique properties, such as a semi-adaptive grid, a gas volume fraction, different densities of ice and brine, and slush formation during snow melt. The thermodynamic properties and phase composition are calculated according to mushy-layer theory. SASMIM uses a finite volume approach to explicitly conserve enthalpy and mass. I introduce parametrizations for each of the three desalination processes which occur in sea ice, namely gravity drainage, flushing, and flooding. Our gravity drainage parametrization takes the convective nature of the process into account and is able to reproduce laboratory measurements and fulfill theoretical expectations, a feat unaccomplished by previously proposed parametrizations. In contrast to other attempts, my flushing parametrization explicitly accounts for horizontal flows close to the ice surface. Flooding is the least well understood of the three processes, and no data or theory are available to evaluate the performance of the model. SAMSIM’s parametrized salinity evolution agrees well with sea-ice characteristics derived from ice-core data. By forcing SAMSIM with atmospheric reanalysis data from the Arctic I learn that the depth of gravity drainage varies strongly over time and can span the full ice depth. I also discover that gravity drainage is not restricted to the growth season as previously thought, but is also present as the ice warms and begins to melt. While gravity drainage is most effective in the lower half of warming sea ice, flushing desalinates the upper half of sea ice once surface melt sets in. By comparing the reanalysis forced runs with and without salinity parametrizations I find that prescribing a depth dependent salinity profile characteristic of multi-year ice leads to deviations below 5 % on average. I also introduce a second set of parametrizations which aim to imitate the salinity profile of the original more complex parametrizations but at a reduced computational cost. These simplified parametrizations only reduce the absolute error of the prescribed salinity profile by approximately 1 %.
CHEMICAL COMPOSITION, ANTIMICROBIAL, ANTIOXIDANT AND CYTOTOXIC ACTIVITIES OF EUCALYPTUS CHAPMANIANA GROWN IN IRAQ

The chemical composition of the essential oils extracted from immature flowers, leaves and seeds of Eucalyptus chapmaniana grown in Iraq were analyzed for the first time by gas chromatography/mass spectrometry. Twenty-four different compounds were identified and the predominant compound is eucalyptol, which accounted for 59.9, 55.6 and 8.6% of total compounds, respectively. To asses the possible therapeutic uses of the extracts, their antioxidant properties were assessed via DPPH free radical scavenging. The extracts showed significant antioxidant and antimicrobial activities against Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumonia, Proteus volgaris, Staphylococcus aureus and Candida albicans. The cytoxicity of flower extract against the Human Leukemia (HL-60) cells was evaluated and the extracts significantly reduced the viability of HL-60 cells in a dose- and time-dependent response relationship. The results indicated that essential oils from immature flowers are highly cytotoxic to HL-60 cells and that their antitumor potential was confirmed.
of Geophysical Research : Earth Surface Missing Evidence of Widespread Subglacial Lakes at Recovery Glacier , Antarctica

Recovery Glacier reaches far into the East Antarctic Ice Sheet. Recent projections point out that its dynamic behavior has a considerable impact on future Antarctic ice loss (Golledge et al., 2017, https://doi.org/10.1002/2016GL072422). Subglacial lakes are thought to play a major role in the initiation of the rapid ice flow (Bell et al., 2007, https://doi.org/10.1038/nature05554). Satellite altimetry observations have even suggested several actively filling and draining subglacial lakes beneath the main trunk (B. E. Smith et al., 2009, https://doi.org/10.3189/002214309789470879). We present new data of the geometry of this glacier and investigate its basal properties employing radio-echo sounding. Using ice sheet modeling, we were able to constrain estimates of radar absorption in the ice, but uncertainties remain large. The magnitude of the basal reflection coefficient is thus still poorly known. However, its spatial variability, in conjunction with additional indicators, can be used to infer the presence of subglacial water. We find no clear evidence of water at most of the previously proposed lake sites. Especially, locations, where altimetry detected active lakes, do not exhibit lake characteristics in radio-echo sounding. We argue that lakes far upstream the main trunk are not triggering enhanced ice flow, which is also supported by modeled subglacial hydrology.
of Geophysical Research : Earth Surface Slow-slip events on the Whillans Ice Plain , Antarctica , described using rate-and-state friction as an ice stream sliding law

The Whillans Ice Plain (WIP), Antarctica, experiences twice daily tidally modulated stick-slip cycles. Slip events last about 30 min, have sliding velocities as high as ∼0.5 mm/s (15 km/yr), and have total slip ∼0.5 m. Slip events tend to occur during falling ocean tide: just after high tide and just before low tide. To reproduce these characteristics, we use rate-and-state friction, which is commonly used to simulate tectonic faulting, as an ice stream sliding law. This framework describes the evolving strength of the ice-bed interface throughout stick-slip cycles. We present simulations that resolve the cross-stream dimension using a depth-integrated treatment of an elastic ice layer loaded by tides and steady ice inflow. Steady sliding with rate-weakening friction is conditionally stable with steady sliding occurring for sufficiently narrow ice streams relative to a nucleation length. Stick-slip cycles occur when the ice stream is wider than the nucleation length or, equivalently, when effective pressures exceed a critical value. Ice streams barely wider than the nucleation length experience slow-slip events, and our simulations suggest that the WIP is in this slow-slip regime. Slip events on the WIP show a sense of propagation, and we reproduce this behavior by introducing a rate-strengthening region in the center of the otherwise rate-weakening ice stream. If pore pressures are raised above a critical value, our simulations predict that the WIP would exhibit quasi-steady tidally modulated sliding as observed on other ice streams. This study validates rate-and-state friction as a sliding law to describe ice stream sliding styles. Plain Language Summary The Whillans Ice Plain, a 120 km wide region of the West Antarctic Ice Sheet, experiences slip events that bear similarity to tectonic earthquakes. During a slip event, the entire 120 km region slides forward by about half a meter over a period of about 30 min. Remarkably, on most days these slip events occur just after high tide and just before low tide. These slip events are much slower and have much lower ground accelerations than typical tectonic earthquakes of this size. We create computer simulations of these slip events using a type of friction law originally discovered in the study of tectonic earthquake. We show that the slow-slip events on the Whillans Ice Plain are similar to slow-slip events in subduction zones in that they nucleate over very long distances. Our model also recreates the general type of behavior observed in other parts of Antarctica where slip events do not occur. By better describing the friction at the base of the ice sheet, we hope to improve the computer simulations of ice sheet dynamics that constrain estimates of future sea level rise.
