description: Currently-proposed galaxy quenching mechanisms predict very different behaviours during major halo mergers, ranging from significant quenching enhancement (e.g., clump-induced gravitational heating models) to significant star formation enhancement (e.g., gas starvation models). To test real galaxies' behaviour, we present an observational galaxy pair method for selecting galaxies whose host haloes are preferentially undergoing major mergers. Applying the method to central L* (10^10 Msun < M_* < 10^10.5 Msun) galaxies in the Sloan Digital Sky Survey (SDSS) at z<0.06, we find that major halo mergers can at most modestly reduce the star-forming fraction, from 59% to 47%. Consistent with past research, however, mergers accompany enhanced specific star formation rates for star-forming L* centrals: ~10% when a paired galaxy is within 200 kpc (approximately the host halo's virial radius), climbing to ~70% when a paired galaxy is within 30 kpc. No evidence is seen for even extremely close pairs (<30 kpc separation) rejuvenating star formation in quenched galaxies. For galaxy formation models, our results suggest: (1) quenching in L* galaxies likely begins due to decoupling of the galaxy from existing hot and cold gas reservoirs, rather than a lack of available gas or gravitational heating from infalling clumps, (2) state-of-the-art semi-analytic models currently over-predict the effect of major halo mergers on quenching, and (3) major halo mergers can trigger enhanced star formation in non-quenched central galaxies.
Characterization and regulation of cytosolic phospholipase A(2) activity following bradykinin stimulation of rabbit cortical collecting duct cells.
Creators: name: Lal, Mark A.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1997
Subjects: subject: Biology, Cell.

description: The mammalian kidney, in particular the collecting duct segment of the nephron, is a major site of renal sodium and water reabsorption. One of the many agonists known to regulate collecting duct function is bradykinin (BK), a nonapeptide which exerts natriuretic and diuretic effects through its ability to increase arachidonic acid (AA) availability and prostaglandin production. Evidence presented herein indicates that 85 kDa cytosolic phospholipase A$\sb2$ (cPLA$\sb2)$ is the enzyme accountable for BK-mediated AA. This is based on the following observations: RCCD cells express cPLA$\sb2$ protein, an arachidonyl trifluoromethyl ketone inhibitor of cPLA$\sb2$ completely blunted BK-stimulated AA release, both basal and BK-stimulated PLA$\sb2$ activities were significantly diminished following treatment with an antibody to this enzyme, and finally, PLA$\sb2$ in vitro activity could be stimulated by submillimolar calcium concentrations and was dithiothreitol (DTT)-insensitive. Strategies were also employed to reveal the involvement of protein kinase C (PKC) in BK-mediated AA release, cPLA$\sb2$ activation and cPLA$\sb2$ phosphorylation. Chemical inhibition of PKC reduced both BK-stimulated AA release and cPLA$\sb2$ activity; however, BK-stimulated AA release appeared limited by calcium mobilization rather than by PKC. Cytosolic PLA$\sb2$ activity could be stimulated by phorbol ester (PMA) and the magnitude of this activation was similar to that caused by BK. A direct correlation between the level of cPLA$\sb2$ phosphorylation and activation was confirmed by the phosphatase-mediated reversal of both BK- and PMA-stimulated responses. Furthermore, the increase in cPLA$\sb2$ phosphorylation was found to occur on serine residues. (Abstract shortened by UMI.)

Subjects: subject: History, Canadian.

description: Cette these examine l'evolution parallele de la justice penale militaire et de l'office du juge-avocat general des origines a aujourd hui. La justice militaire au sein de l'armee britannique a ete pendant des siecles administree exclusivement par le commandement, c'est a dire le pouvoir executif. Les cours martiales sont alors des instruments de ce pouvoir. La regle de droit et les juristes n'ont pas leur place dans ce systeme. L'exercice de la prerogative du commandement fait l'objet d'une surveillance par le juge-avocat general. Cet office civil est confiee a un juriste. Ses interventions fondees sur le droit son souvent considerees comme une menace a l'autorite du commandement et donc a la discipline. Ses opinions ne lient les autorites militaires. Au Canada en 1911, la charge de JAG est confiee a un militaire clairement subordonne au commandement. Chez-nous le JAG est complice du commandement dans l'exercice de sa prerogative. Le declin de la prerogative du commandement au profit d'un pouvoir judiciaire independant amoree apres la deuxieme guerre mondiale a eu un impact significatif sur le systeme et sur l'office du JAG. Les roles du JAG n'ont cesse de diminuer, surtout depuis l'avenement de la Charte. Nous croyons que cet office doit etre reevalue a la lumiere des changements survenus et des nouvelles valeurs du systeme de justice penale militaire.

description: We study the rest-frame ultraviolet (UV) sizes of massive (~0.8 ´ 1011M☉) galaxies at 3.4 ⩽ z < 4.2, selected from the FourStar Galaxy Evolution Survey, by fitting single Sérsic profiles to Hubble Space Telescope/WFC3/ F160W images from the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey. Massive quiescent galaxies are very compact, with a median circularized half-light radius re = 0.63 ± 0.18 kpc. Removing 5 16 (31%) sources with signs of active galactic nucleus activity does not change the result. Star-forming galaxies have re = 2.0 ± 0.60 kpc, 3.2 ± 1.3´larger than quiescent galaxies. Quiescent galaxies at z ~ 4 are on average 6.0 ± 1.7´smaller than at z ~ 0 and 1.9 ± 0.7´smaller than at z ~ 2. Star-forming galaxies of the same stellar mass are 2.4 ± 0.7´smaller than at z ~ 0. Overall, the size evolution at 0 < z < 4 is well described by a power law, with re 5.08 0.28(1 z) = ± + -1.44±0.08 kpc for quiescent galaxies and r 6.02 0.28(1 z) e = ± + -0.72±0.05 kpc for star-forming galaxies. Compact star-forming galaxies are rare in our sample: we find only1 14 (7%) with re (M 10 M ) 1.5 11 0.75 < ☉ , whereas 13 16 (81%) of the quiescent galaxies are compact. The number density of compact quiescent galaxies at z ~ 4 is 1.8 ± 0.8 ´ 10-5 Mpc-3 and increases rapidly, by >5´, between 2 < z < 4. The paucity of compact star-forming galaxies at z ~ 4 and their large rest-frame UV median sizes suggest that the formation phase of compact cores is very short and/or highly dust obscured.
Young people, their technology and the fear in schools
Creators: name: Warner, David
Publisher: name: Swinburne
Year: 2024

description: This paper is a conversation piece about the failure of schooling to embrace the technology that 21st century young people use as part of their lives. It directs attention to the fears that schools - and probably many adults - have of young people and their technology. It argues that it is not technology that is the issue but the 20th century attitudes of schools, schooling systems and governments. It is this attitude that actually controls schools, their young people and the amount of and manner in which technology is used. It briefly explores young people and their technologies and looks ahead to emerging technologies, but again all within the context that it is not as much about technology as the culture of schools. Technology, through the Internet, enabled the global knowledge economy but schools have not really embraced either. The paper concludes with the possibility that young people empowered by their technology may well rebel against the irrelevance of their schooling and its controlling culture, particularly technology.

description: We report on the setup and initial discoveries of the Northern High Time Resolution Universe survey for pulsars and fast transients, the first major pulsar survey conducted with the 100-m Effelsberg radio telescope and the first in 20 years to observe the whole northern sky at high radio frequencies. Using a newly developed 7-beam receiver system combined with a stateof- the-art polyphase filterbank, we record an effective bandwidth of 240MHz in 410 channels centred on 1.36 GHz with a time resolution of 54 μs. Such fine time and frequency resolution increases our sensitivity to millisecond pulsars and fast transients, especially deep inside the Galaxy, where previous surveys have been limited due to intrachannel dispersive smearing. To optimize observing time, the survey is split into three integration regimes dependent on Galactic latitude, with 1500, 180 and 90-s integrations for latitude ranges |b| < 3.°5, |b| < 15° and |b| > 15°, respectively. The survey has so far resulted in the discovery of 15 radio pulsars, including a pulsar with a characteristic age of ~18 kyr, PSR J2004+3429, and a highly eccentric, binary millisecond pulsar, PSR J1946+3417. All newly discovered pulsars are timed using the 76-m Lovell radio telescope at the Jodrell Bank Observatory and the Effelsberg radio telescope. We present timing solutions for all newly discovered pulsars and discuss potential supernova remnant associations for PSR J2004+3429.
Dynamic kinetic resolution: Diastereoselective amination of alpha-halo esters and alpha-halo imidazolidinones.
Creators: name: O'Meara, Jeffrey A.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1995
Subjects: subject: Chemistry, Organic.

description: The synthesis of optically active N-protected $\alpha$-amino esters and $\alpha$-amino imidazolidinones via a dynamic kinetic resolution protocol will be discussed. The methodology is based on fundamental reactivity differences between diastereomeric $\alpha$-halo esters and $\alpha$-halo imidazolidinones. The process involves nucleophillic displacement of the diastereomeric $\alpha$-halogenated esters and imidazolidinones with benzylamine. The corresponding displacement products are obtained with 70 - $>$ 98% de. Both absolute configurations are possible at the aminated postion by appropriate choice of the chiral auxiliary. The application of this methodology towards the synthesis of several optically active $\alpha$-amino esters was investigated. A five step sequence, starting from commercially available acid chlorides, was developed for synthesizing $\alpha$-amino esters in $\sim$40% overall yield. By utilizing dibenzylamine as the nucleophile, the DKR process has been effectively utilized in an approach to Reetz aldehydes ($\alpha$-dibenzylamino aldehydes). The increased bulk of dibenzylamine provides increased diastereoselectivity relative to benzylamine and the Reetz aldehyde precursors are obtained with a high degree of optical purity. Mechanistic aspects the reaction will also be discussed.

Subjects: subject: Engineering, Electronics and Electrical.

description: The thesis proposes a framework for applying effective QoS techniques in a Diffserv MPLS network to ensure predictable levels of QoS at the network layer to delay-sensitive applications. This approach will enable network edge routers to discriminate against classes of traffic, and dynamically map it into pre-established Label Switched Paths (LSPs) that emulate classes of service (e.g. gold, silver, etc.). We investigate the several contributors of delays in a packet switched IP network in order to ensure minimal service end-to-end delay. We present a number of scenarios to prove our conclusions. Our work is first simulated on a network simulation tool, Optimized Network Engineering Tool (OPNET) [16]. The second phase of the experimental work is to realize, and evaluate our model on an MPLS test-bed of networked PCs running on Linux Operating System (OS) and connecting a number of Multimedia Streaming server/client applications. The Linux kernel is patched so it becomes Diffserv MPLS-enabled. (Abstract shortened by UMI.)
Equalizer design for discrete wavelet multitone transceiver.
Creators: name: Tressler, Neera.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2002
Subjects: subject: Engineering, Electronics and Electrical.

description: Discrete Wavelet Multi-tone (DWMT) is a multi-carrier technique that uses Wavelet Transform (WT) for modulation. A DWMT communication system is designed and an attempt is made to optimize the equalizer design and the structure of the DWMT receiver. Three plausible receiver designs consisting of a time domain equalizer (TEQ), several frequency domain equalizers (FEQ) and a combination of a simple TEQ and simple FEQs, are examined. The Linear equalizer (LE) is used as the TEQ, whereas the LE and the Decision Feedback Equalizer (DFE) are used as FEQs. These designs are simulated, tested on different twisted pair Very high-speed Digital Subscriber Loop (VDSL) channels and compared with each other in terms of their complexity and performance. The results indicate that the receiver designs consisting of only TEQ or only FEQs do not give a good signal reconstruction, in spite of using a large number of taps in the equalizers. On the other hand, the receiver structure consisting of a combination of a TEQ and FEQs was found to give a better performance, with lesser complexity in both the TEQ and the FEQs. A few taps in TEQ are found to be sufficient for eliminating most of the ISI in the signal. After demodulation, an FEQ with a few taps for each subchannel is sufficient to equalize the signal further and give a much lower Symbol Error Rate SER, as compared to both the previous structures. The DFE was found to give better performance than the LE. We conclude that the receiver design consisting of a simple TEQ and simple subchannel DFE-based FEQs, is most suitable for the DWMT transceiver among the three different designs tested for a DWMT system.

description: Background. Palliative care should be provided according to the individual needs of the patient, caregiver and family, so that the type and level of care provided, as well as the setting in which it is delivered, are dependent on the complexity and severity of individual needs, rather than prognosis or diagnosis 1. This paper presents a study designed to assess the feasibility and efficacy of an intervention to assist in the allocation of palliative care resources according to need, within the context of a population of people with advanced cancer. Methods/design. People with advanced cancer and their caregivers completed bi-monthly telephone interviews over a period of up to 18 months to assess unmet needs, anxiety and depression, quality of life, satisfaction with care and service utilisation. The intervention, introduced after at least two baseline phone interviews, involved a) training medical, nursing and allied health professionals at each recruitment site on the use of the Palliative Care Needs Assessment Guidelines and the Needs Assessment Tool: Progressive Disease - Cancer (NAT: PD-C); b) health professionals completing the NAT: PD-C with participating patients approximately monthly for the rest of the study period. Changes in outcomes will be compared pre-and post-intervention. Discussion. The study will determine whether the routine, systematic and regular use of the Guidelines and NAT: PD-C in a range of clinical settings is a feasible and effective strategy for facilitating the timely provision of needs based care.
Student Satisfaction and Self Report CPR Competency: Heartcode BLS Courses, Instructor-Led CPR Courses, and Monthly VAM Practice for CPR Skill Maintenance
Creators: name: Montgomery, Cecily Ann
Publisher: name: Washington State University
Year: 2011

description: Correctly performed cardiopulmonary resuscitation (CPR) can improve survival after sudden cardiac arrest; however, research demonstrates that CPR skills are not retained well. Objective: This quasi-experimental longitudinal study among 606 nursing students in diploma, associate degree, and baccalaureate nursing programs around the US determined if type of CPR course or monthly practice affects CPR skill retention, confidence, and training satisfaction. Ten nursing programs were randomized to course type, HeartCode™ BLS or an instructor-led (IL) course, and then randomized to practice group, 6 minutes of monthly practice or no further practice. Method: End of study survey results were compiled and reported as percentages. Short answer data was grouped by category for reporting. Results: Significantly fewer HeartCode™ BLS students (n=126, 87%) were satisfied with their CPR training compared to 95% (n=183) of IL students. Students who practiced CPR monthly (n=146, 90%) were significantly more confident than students who did no practice (n=136, 78%). Fewer students who practiced monthly thought their initial training was just right (n=101, 61%) than those who did no practice (n=131, 74%). Conclusions: Monthly practice improved CPR confidence, but course type did not. However, the CPR skills of students who took HeartCode™ BLS were better. Students were most satisfied when they participated in the IL course and frequent practice. According to students, future CPR practice should include: more practice and immediate feedback, more instructor involvement, and more realistic scenarios.

description: While therapeutic drug monitoring (TDM) that uses blood as the biological matrix is the traditional gold standard, this practice may be impossible, impractical, or unethical for some patient populations (e.g., elderly, pediatric, anemic) and those with fragile veins. In the context of finding an alternative biological matrix for TDM, this manuscript will provide a qualitative review on: (1) the principles of TDM; (2) alternative matrices for TDM; (3) current evidence supporting the use of interstitial fluid (ISF) for TDM in clinical models; (4) the use of microneedle technologies, which is potentially minimally invasive and pain-free, for the collection of ISF; and (5) future directions. The current state of knowledge on the use of ISF for TDM in humans is still limited. A thorough literature review indicates that only a few drug classes have been investigated (i.e., anti-infectives, anticonvulsants, and miscellaneous other agents). Studies have successfully demonstrated techniques for ISF extraction from the skin but have failed to demonstrate commercial feasibility of ISF extraction followed by analysis of its content outside the ISF-collecting microneedle device. In contrast, microneedle-integrated biosensors built to extract ISF and perform the biomolecule analysis on-device, with a key feature of not needing to transfer ISF to a separate instrument, have yielded promising results that need to be validated in pre-clinical and clinical studies. The most promising applications for microneedle-integrated biosensors is continuous monitoring of biomolecules from the skin’s ISF. Conducting TDM using ISF is at the stage where its clinical utility should be investigated. Based on the advancements described in the current review, the immediate future direction for this area of research is to establish the suitability of using ISF for TDM in human models for drugs that have been found suitable in pre-clinical experiments.

An electrochemical quartz crystal microbalance study of adsorption processes at gold electrodes.
Creators: name: Ding, Tao.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1993
Subjects: subject: Chemistry, Analytical.

description: This thesis describes a study of the adsorption of anions and neutral organic molecules at gold electrodes using the electrochemical quartz crystal microbalance (EQCM). Differential capacitance, cyclic voltammetry and ring-disk methods were also used to provide further data. In perchlorate solutions (except 0.1 M HClO$\sb4)$ mass responses are flat at potentials positive of the potential of zero charge (E$\sb{\rm pzc})$ in the double layer region of potential. This seems to agree with the accepted view that perchlorate adsorbs weakly at gold. When phosphate is added to 0.1 M KClO$\sb4$ the mass response is seen to increase with increasing potential positive of the E$\sb{\rm pzc}.$ The size of this increase is proportional to the concentration of phosphate species. Differential capacitance and cyclic voltammetry data confirm the adsorption of phosphate species. Adsorption of 4,4$\sp\prime$-bipyridyl was studied because it is one of many compounds that, when adsorbed, promote the electrochemistry of cytochrome c. The presence of 4,4$\sp\prime$-bipyridyl at the electrode surface removes the mass change seen in phosphate buffer and produces a flat mass change over the potential range from $-$0.6 V to 0.6 V. Replacement of adsorbed ions is confirmed by differential capacitance experiments. When the electrode surface is oxidised in the presence of 4,4$\sp\prime$-bipyridyl, no significant mass increase is observed. The mass response also shows that reversal of the place exchange process (where an O species is inserted into the gold lattice upon oxidation) leads to removal of a small amount of adsorbate and an irreversible loss of material from the electrode. A possible mechanism has been proposed which would account for these observations. Finally, EQCM responses show clearly that adsorbed bipyridyl is easily removed from the electrode surface by washing.

description: In order to understand which process (e.g. galactic winds, cold accretion) is responsible for the cool (T~10^4 K) halo gas around galaxies, we embarked on a program to study the star-formation properties of galaxies selected by their MgII absorption signature in quasar spectra. Specifically, we searched for the H-alpha line emission from galaxies near very strong z=2 MgII absorbers (with rest-frame equivalent width EW>2 AA) because these could be the sign-posts of outflows or inflows. Surprisingly, we detect H-alpha from only 4 hosts out of 20 sight-lines (and 2 out of the 19 HI-selected sight-lines), despite reaching a star-formation rate (SFR) sensitivity limit of 2.9 M/yr (5-sigma) for a Chabrier initial mass function. This low success rate is in contrast with our z=1 survey where we detected 66% (14/21) of the MgII hosts. Taking into account the difference in sensitivity between the two surveys, we should have been able to detect >11.4 of the 20 z=2 hosts whereas we found only 4 galaxies. Interestingly, all the z=2 detected hosts have observed SFR greater than 9 M/yr, well above our sensitivity limit, while at z=1 they all have SFR less than 9 M/yr, an evolution that is in good agreement with the evolution of the SFR main sequence. Moreover, we show that the z=2 undetected hosts are not hidden under the quasar continuum after stacking our data and that they also cannot be outside our surveyed area. Hence, strong MgII absorbers could trace star-formation driven winds in low-mass halos (Mhalo < 10^{10.6} Msun). Alternatively, our results imply that z=2 galaxies traced by strong MgII absorbers do not form stars at a rate expected (3--10 M/yr) for their (halo or stellar) masses, supporting the existence of a transition in accretion efficiency at Mhalo ~ 10^{11} Msun. This scenario can explain both the detections and the non-detections.
Telecommunications across borders: Refugees' technology use during displacement

description: This article reports on recent research examining refugees as a particular user group of communication technologies. The term 'refugee' refers to all people who are exposed to refugee-type experiences and may include displaced people, asylum seekers and resettled refugees who have been granted residency in Australia. A review of literature has found that refugees as technology users have had very little attention across different disciplines, although the research has shown that technology is key to sustaining emotional wellbeing and precarious connections with family members when displaced. In particular, the telephone is the most critical technology for refugees in terms availability and familiarity. However, the access and affordability of telecommunications services and other technologies during displacement impacts on refugees' adoption and use of technology in the settlement process.

description: Background: Technetium-99m-hydrazinonicotinamide-Tyr3-octreotide (99mTc-HYNIC-TOC) is recognized as a promising radiopharmaceutical for diagnosing neuroendocrine tumors (NETs). However, 99mTc-HYNIC-TOC dosimetry has been investigated only for adults. As pediatric radionuclide therapies become increasingly common, similar dosimetric studies for children are urgently needed. The aim of this study is to report personalized image-based biodistributions and dosimetry evaluations for children studies performed using 99mTc-HYNIC-TOC and to compare them with those from adult subjects. Eleven children/teenage patients with suspected or diagnosed NETs were enrolled. Patient imaging included a series of 2–3 whole-body planar scans and SPECT/CT performed over 2–24 h after the 99mTc-HYNIC-TOC injections. The time-integrated activity coefficients (TIACs) were obtained from the hybrid planar/SPECT technique. Patient-specific doses were calculated using both the voxel-level and the organ-level approaches. Estimated children doses were compared with adults’ dosimetry. Results: Pathologic uptake was observed in five patients. TIACs for normal organs with significant uptakes, i.e., kidneys, spleen, and liver, were similar to adults’ TIACs. Using the voxel-level approach, the average organ doses for children were 0.024 ± 0.009, 0.032 ± 0.017, and 0.017 ± 0.007 mGy/MBq for the kidneys, spleen, and liver, respectively, which were 30% larger than adults’ doses. Similar values were obtained from the organ-level dosimetry when using OLINDA with adapted organ masses. Tumor doses were 0.010–0.024 mGy/MBq. However, cross-organ contributions were much larger in children than in adults, comprising about 15–40% of the total organ/tumor doses. No statistical differences were found between mean doses and dose distributions in patients with and without pathologic uptakes. Conclusion: Although the children TIACs were similar to those in adults, their doses were about 30% higher. No significant correlation was found between the children’s doses and their ages. However, substantial inter-patient variability in radiotracer uptake, indicating disparity in expression of somatostatin receptor between different patients, emphasizes the importance and necessity of patient-specific dosimetry for clinical studies.

description: Cutaneous squamous cell carcinoma (cSCC) is the second most common skin cancer and usually progresses from a UV-induced precancerous lesion termed actinic keratosis (AK). Despite various efforts to characterize these lesions molecularly, the etiology of AK and its progression to cSCC remain partially understood. Here, we use Infinium MethylationEPIC BeadChips to interrogate the DNA methylation status in healthy, AK and cSCC epidermis samples. Importantly, we show that AK methylation patterns already display classical features of cancer methylomes and are highly similar to cSCC profiles. Further analysis identifies typical features of stem cell methylomes, such as reduced DNA methylation age, non-CpG methylation, and stem cell-related keratin and enhancer methylation patterns. Interestingly, this signature is detected only in half of the samples, while the other half shows patterns more closely related to healthy epidermis. These findings suggest the existence of two subclasses of AK and cSCC emerging from distinct keratinocyte differentiation stages.
Traduction et traductibilité chez Jacques Derrida.

description: We are presenting here, in three chapters centered around the notions of sign, translatability and context, a synthesis of Derrida's ideas about the theorization of translation. His thorough reading sheds light on the metaphysical, rather than purely scientific, ground of linguistics and semiotics, as well as on the fundamental role the idea of translatability plays in Western thinking. The two theological models of translatability are also considered, i.e., the logocentric and the Babelian approach, which opens up a paradoxical perspective, where translation appears to be at once necessary and impossible. This paradox emphasizes the intrinsically human dimension of translation, which then becomes a tool for knowledge, human exchanges, responsibility and creativity in attributing meaning and direction. We are finally presenting the new conceptual tools Derrida offers in respect to sign, reading, and writing, tools which reveal the complexity of the subject, but, conversely, position the translator's decision making and responsibility at the heart of the issue.

description: The two-dimensional diffusion of isolated molecular tracers at the water-n-alkane interface was studied with fluorescence correlation spectroscopy. The interfacial diffusion coefficients of larger tracers with a hydrodynamic radius of 4.0 nm agreed well with the values calculated from the macroscopic viscosities of the two bulk phases. However, for small molecule tracers with hydrodynamic radii of only 1.0 and 0.6 nm, notable deviations were observed, indicating the existence of an interfacial region with reduced effective viscosity and increased mobility.

description: Background Cardiovascular magnetic resonance feature tracking (CMR-FT) is a novel tissue tracking technique developed for noninvasive assessment of myocardial motion and deformation. This preliminary study aimed to evaluate the observer’s reproducibility of CMR-FT in a small animal (mouse) model and define sample size calculation for future trials. Methods Six C57BL/6 J mice were selected from the ongoing experimental mouse model onsite and underwent CMR with a 3 Tesla small animal MRI scanner. Myocardial deformation was analyzed using dedicated software (TomTec, Germany) by two observers. Left ventricular (LV) longitudinal, circumferential and radial strain (EllLAX, EccSAX and ErrSAX) were calculated. To assess intra-observer agreement data analysis was repeated after 4 weeks. The sample size required to detect a relative change in strain was calculated. Results In general, EccSAX and EllLAX demonstrated highest inter-observer reproducibility (ICC 0.79 (0.46–0.91) and 0.73 (0.56–0.83) EccSAX and EllLAX respectively). In contrast, at the intra-observer level EllLAX was more reproducible than EccSAX (ICC 0.83 (0.73–0.90) and 0.74 (0.49–0.87) EllLAX and EccSAX respectively). The reproducibility of ErrSAX was weak at both observer levels. Preliminary sample size calculation showed that a small study sample (e.g. ten animals to detect a relative 10% change in EccSAX) could be sufficient to detect changes if parameter variability is low. Conclusions This pilot study demonstrates good to excellent inter- and intra-observer reproducibility of CMR-FT technique in small animal model. The most reproducible measures are global circumferential and global longitudinal strain, whereas reproducibility of radial strain is weak. Furthermore, sample size calculation demonstrates that a small number of animals could be sufficient for future trials.

description: The lens cells of humans with chronic hyperglycemia show a progressive accumulation of sorbitol by aldose reductase catalysis that ends with cell lysis. Therefore, this work aims to explore metabolites in native plants that prevent cataracts through inhibition of the enzyme aldose reductase. The scrutiny was performed using bioinformatics, chemicals, enzymes, and cataract ex vivo prevention techniques. Eleven Eupatorium spp. were the natural resources explored. Five of them were selected to continue with the phytochemical scrutiny. Twelve pure phytometabolites were obtained with an inhibitory effect on the enzyme. Nine of them were subject to the accepted heuristic rules for drug-likeness. With this analysis, a possible active principle emerged a phenolic compound: methylripariochromene A. An apparent mixed catalytic mechanism carries out the inhibition of enzyme catalysis. Molecular docking and molecular dynamic simulations helped us understand their coupling in the active site of AR, finding an agreement between experimental and computational data. Methylripariochromene A prevented experimental cataract formation in rabbit lens cultured ex vivo.
The Effects of Sex Education on Adolescent Contraceptive Use

description: By the time adolescents in the United States graduate from high school, more than 60% report having had sex. Many of them are engaging in unprotected sexual\nintercourse, increasing the risk of unwanted pregnancies and sexually transmitted diseases. A contributing factor to this behavior may be the lack of consistent health education protocols between local school districts. The purpose of this literature review was to analyze research findings that have attempted to evaluate sex education programs and the effects they have on adolescent contraceptive use. The studies reviewed generally provide mixed results. Often the content and duration of the educational interventions were poorly described and varied dramatically between studies. Further research is warranted until effective sex education programs are identified and replicated across multiple settings. Consistent implementation of these refined educational interventions will provide a more accurate picture to researchers and clinicians. Matching the scope of this problem to the commitment towards successful sex education programs requires a collaborative effort from teachers, healthcare providers, parents, community leaders, and adolescents themselves.

description: In dieser Studie wurde in drei Schritten analysiert, ob Airgunsignale, die für die Erkundung des Meeresbodens eingesetzt werden, die Kommunikationsreichweiten von marinen Säugetieren in großen Entfernungen beeinflussen können: Zuerst wurde eine Literaturrecherche über die betroffenen Arten und ihre Vokalisation durchgeführt. Im zweiten Schritt wurde die Schallausbreitung von Airgunsignalen bis in Entfernungen von 2.000 km von der Quelle modelliert. Im dritten Schritt wurden die modellierten Störsignale mit den Vokalisationen mariner Säugetiere (Finnwal, Blauwal und Weddellrobbe) überlagert, um die Distanzen zu berechnen in denen deren Kommunikationsreichweiten potentiell verkleinert werden.

description: The flagellated parasite, Trichomonas vaginalis, is one of the most commonly encountered genital pathogens. Despite its frequent incidence, pathogenic mechanisms of T. vaginalis are not well characterized. The first section of this project involved the ability of T. vaginalis to grow in serum-free medium. By employing a cell culture system, it was demonstrated that T. vaginalis can exhibit growth in the absence of serum. McCoy cells utilized in the system did not appear to secrete growth factors responsible for this proliferation. The second part of this project involved establishment of a mouse model for T. vaginalis infection and subsequent employment of the model in determining the effects of T. vaginalis on vaginal flora and pH. After the endemic flora and pH in mice were identified, other factors which may have influenced flora, were investigated. Both estrogenization and inoculation of media appeared to have no effect on individual vaginal species, and only appeared to increase the number of species found per mouse. T. vaginalis infection did not appear to alter vaginal pH or flora in vivo. In vitro studies of the interaction between T. vaginalis and Lactobacillus acidophilus indicated that indirect factors, such as secreted products, may mediate the alteration in flora and pH evident during infection.
