Small Extracellular Vesicles From Human Adipose-derived Stem Cells: A Potential Promoter of Keeping Fat Graft Survival

Background: Small extracellular vesicles (sEVs) with genetic information secreted by cells play a crucial role in the cellular microenvironment. In this study, our purpose is to explore the characteristics of the small extracellular vesicles of human adipose-derived stem cells (hADSC-sEVs) and studied the role of hADSC-sEVs in improving the survival rate of grafted fat.Methods: In the present study, we used the transmission electron microscopy, nano-tracking analysis, nanoflow surface protein analysis, zeta potential value to identify sEVs. SEVs' trajectory was traced dynamically to verify whether hADSC-sEVs can be internalized into human umbilical vein endothelial cells (HUVECs) in vitro. The angiogenic property of hADSC-sEVs was observed by measuring the volume, weight and histological analysis of the grafted fats in nude mice modles. Results: Our research showed that the extracellular vesicles were sEVs with double-layer membrane structure and the diameter of which is within 30-150nm. hADSC-sEVs exert biological influence mainly through internalization into cells. Compared with the control group, the hADSC-sEVs group had a significantly higher survival rate of grafted fat, morphological integrity and a lower degree of inflammation and fibrosis. And immunohistochemistry showed that hADSC-sEVs significantly increased the neovascularisation and the expression of CD34, VEGFR2 and KI-67 in the graft tissue. Conclusions: As a potential nanomaterial, hADSC-sEVs has been explored in the field of cell-free application of stem cell technology. hADSC-sEVs promoted the survival of grafted fats by promoting the formation of new blood vessels, which is another promising progress in the field of regenerative medicine. We believe that hADSC-sEVs will have a broad application prospect in the field of regenerative medicine in the future.
The Effects of Neural Therapy Using 1% Procaine Injections on Pain and Autonomic Nervous System in Patients with Neck Pain

The effects of neural therapy using 1% procaine injections on pain and autonomic nervous system in patients with neck pain. Abstracts Background: Neural therapy, is a treatment approach that targets the nervous system by altering resting potential through injecting a local anesthetic. Neural therapy can be used to treat local tissues such as trigger points. It was the aim of this study to evaluate the short-term effect of neural therapy, using 1% procaine injections at cervicothoracic region, in subjects with chronic cervical spine pain on the autonomic nervous system. The secondary aim was to investigate if neural therapy resulted in immediate change in reported pain. Methods: A convenience sample of 22 subjects were recruited for this study. Each subjected reported pre intervention pain level. After this they underwent an automated pupillometry measurement for 1 minute. Following this they received the neural therapy intervention paravertebrally and an immediate pupil measurement followed. A third pupillometry measure was taken 4 minutes later. After this the subject reported post intervention pain level. Outcomes: There was no significant change in the pupil measurements in both the right and left eye (p>0.05). There was a significant reduction difference in pain report post testing (p< 0.01). Discussion: The results of this study demonstrate that Neural therapy using 1% procaine has an immediate effect on localized pain perception with eight paravertebral 1% procaine injections at the level of C7-T3. No change in pupil diameter was observed following neural therapy indicating that the balance between the sympathetic and parasympathetic nervous system did not change.
Professional-Database and Staff-Appraisal as Correlates of Principals' Performance in Public Secondary Schools in Delta State, Nigeria

Today's schools operate in a dynamic and rapidly changing environment in which school administrators must adapt and function as change agents to maintain high performance in school administration. TheSchools are confronted by rising pressure from parents and the public to improve teaching and learning experiences to help learners become useful to citizens.The role of school principals has only increased to include the responsibility of leading teaching and learning in a technology-driven learning environment in which learners are at the centre of instructional objectives. The principal can make a spectacular difference to achieve educational goals through an adequate performance of administrative functions. Performance in this context is the act of accomplishing a given task so properly that the intended objectives are achieved successfully and satisfactorily (Ion &Criveanu 2016:179). Samsonwa (2010:10) defined performance as a process of executing a specific work to achieve intended results. Performance is mostly positively associated with effectiveness and efficiency, which respectively entail goal attainment concerning the quality and quantity of resources expended to attain the set goal.
Wealth and Wealth Creation Capacities of Shariah-Compliant Firms: A Study on Impacts of Changes in Shariah-Compliant Status of Firms in Bursa Malaysia

Would shariah-compliant status change wealth and wealth creation capacities of a firm? In Bursa Malaysia about 80 percent of the listed firms have attained the shariah-compliant and placed in shariah-compliant index though a smaller number might subsequently lost the status and removed from the index every year. Judging from the percentage shariah-compliant status seems to be a ‘must have’ certificate for firms in Bursa Malaysia. The question is: does by attaining the shariah-compliant status a firm increase its wealth and wealth creation capacities, or on the contrary, by losing it a firm decrease its wealth creation capacities. This study therefore, investigates the influence of shariah-compliant status on the firms in Bursa Malaysia. Paired sample t-tests are employed on 400 selected firms in KLSI experiencing permanent change of shariah-compliant status from 1999 to 2010 period. It is found that firms would create more wealth or value upon attaining shariah-compliant status. Interestingly, the firms still maintain the same level of wealth even after losing the shariah-compliant status and excluded from the index. An implication for investors and fund managers is that, shariahcompliant status matters in investment decision.
PERMANENT DEFORMATED IN ASPHALT PAVEMENTS CAN BE PREDICTED

The experiments conducted, the results obtained, and the field verification is described of a method (based on simulating the field situation in the laboratory) for predicting rut depths in asphalt concrete pavements. The apparatus and test procedures included a high pressure triaxial chamber with temperature control, electro-hydraulic systems for the independent control of vertical and horizontal stresses, and a variety of ancillary equipment. The equipment was capable of applying repeated axial and laterial stress pulses of any desired shape, in phase with one another, with pulse times ranging from 0.01 to 1.0 sec. The equipment which could apply the axial stress as either tension or compression, could also incorporate rest periods between pulses ranging from 0 to several seconds. Temperature conditiosn could be controlled within a tolerance of plus or minus 0.5 F. It is concluded from the study that the mechanism of rutting in asphalt concrete sections subject to "moderate" tensile stresses is almost entirely due to lateral distortion of the tension zone. An equation is presented which describes the permanent deformation characteristics of asphalt concrete mixtures. Uses for future research are indicated.
A Study on the Histopathological Changes in Cases of Pesticide Poisoning and Proposed Diagnostic Algorithm

Pesticide poisoning in developing world is a global public health problem. Incidences of poisoning are increasing with socio-economic hurdles. Often reporting and chemical examination of samples collected from viscera are difficult to precisely diagnose cases and therefore extensive studies on histopathological corroborations of vital organs such as stomach, liver and kidney is necessary along with socio-demographic data. The common autopsy findings were cyanosis in the lips, in the fingertips and nose. Histological findings in stomach revealed congestion, erosion of muscularis mucosa, submucosal petechial haemorrhages and necrosis. Liver shows congestion, sinusoidal dilution, degeneration of hepatocytes and haemorrhages. Kidney shows tubular necrosis and glomerular congestion. However, history of poisoning along with autopsy and histological findings are considered as strong evidence for acute organophosphorous poisoning.
NDF of the near-field of a strip source in orthogonal directions

In the manuscript, we address the problem of evaluating thenumber of degrees of freedom (NDF) of the field radiated by a strip source along all the directions orthogonal to it. The NDF represents at the same time the number of independent functions required to represent the data with a given degree of accuracy, and the dimension of the unknowns subspace that can be stably reconstructed. For such reason, the knowledge of the NDF gives insight on the forward and on the inverse problems and it represents one of the metrics to evaluate the achievable performance in the inversion.The main difficulty arises since in near-zone the eigenvalueproblem that must be solved for the computation of the NDF,involves a non-convolution and non-bandlimited kernel. In the paper, we show how to overcome this drawback and how to obtain a closed-form expression of the NDF which highlights the role played by the configuration parameters.

Framework for managing multi-cultural project teams

The theory and practice of team integration has changed fundamentally over the last five years, driven by the growing demands of multi-cultural team working and greater understanding of cultural issues and diversity in the internationalised construction environment. According to the literature reviewed, the challenge to the construction industry in both developed and developing countries is to address its poor performance on people management by focusing on multicultural team working. Different reports published by governing bodies in developed countries such as the UK continue to highlight that clients need to improve their understanding of how construction can best meet their business needs and help lead the process of creating integrated teams. Consequently, there have been a number of empirical studies on project teams, particularly focussing on measures of team success. However, the consequences of transition from monoculture to multi-cultural project teams remain largely unexplored in construction management research. cont'd.
Effect of Colostrum Feeding Intervention on the Clinical and Nutritional Outcomes of Very Low Birth Weight Infant

Context: Having premature and very low birth weight infants in the Neonatal Intensive Care Unit (NICU), is disempowering for mothers as they lost autonomy over their behavior and lost autonomy over beginning to establish a close relationship with their neonates. Mothers highly value Breastfeeding/breast milk feeding as it is the ‘one thing that only the mother can do to protect and improve their neonates' health. Aim: Evaluate the effect of colostrum feeding intervention on the clinical and nutritional outcomes of very low birth weight infant. Methods: A quasi-experimental research design utilized to achieve the aim of this study. A convenient sample of 80 mothers of very low birth weight infants subjected to colostrum feeding intervention program. Their 80 very low birth weight infants (divided randomly into two groups) study and control groups to examine the effect of the colostrum feeding intervention on their clinical and nutritional outcomes versus artificial milk feeding. Three research tools used that were structured interview questionnaire, mothers’ practice observation checklist, and very low birth weight clinical and Nutritional outcomes’ record. Results: the study reveals a significant improvement of mother knowledge and practices after colostrum feeding intervention at post and follow up compared to their pre-intervention level. The study also revealed a statistically significant difference in all clinical and nutritional outcomes between infants of the study and control groups. Conclusion: A significant improvement in mothers’ knowledge and practice regarding colostrum feeding intervention. The study group of very low birth weight infants had a rapid growth rate, better nutritional outcomes, lesser complications compared with the control group. The study recommended tailored intervention programs for mother that expecting a very low birth weight infant. Besides, policies for training midwives at maternity centers and hospitals early to initiate colostrum feeding. Further research with larger sample size recommended to determine if early colostrum administration can affect positively on very low birth weight infants outcomes.
AN EVALUATION OF THE INFLUENCE OF ROADSIDE ADVERTISING ON ROAD SAFETY IN THE GREATER MONTREAL REGION

In Quebec, the Loi sur la publicite le long des routes [Act goerning roadside advertising] adopted in 1988 prohibits the installation of billboards within 100 meters of a highway right-of-way. However, the Act does not apply to Urban Community, City and Township territories. This legal loophole has allowed many billboards to be constructed alongside highways in metropolitan areas including Montreal. It has been shown that such billboards are accident-promoting factors. In an urban setting, analysis of the relation between posted advertising - either conventional or variable message type - and increased driver information-processing mental loading defines this problem clearly. In light of its responsibilities in road safety matters, the ministere des transports has therefore proposed amending the Code de la securite routiere to prohibit the installation of such billboards in certain areas deemed particularly at risk.
Use of numerical optimisation to determine on-limit handling behaviour of race cars

The aim of this research is to use numerical optimisation to investigate the on-limit behaviour of an open wheel downforce type race car using the best compromise of modelling accuracy and computational effort. The current state of lap simulation methods are identified, and the GG speed diagram is described. The use of constrained optimisation, which is a form of optimal control, is used to develop the methods described in this thesis. A seven degree of freedom vehicle model validated by other researchers is used for method validation purposes, and is extended, where possible, to make the modelling of vehicle components more physically significant, without adversely affecting the computational time. This research suggests a quasi steady state approach that produces a GG speed diagram and circuit simulation tool that is capable of optimising vehicle parameters and subsystems in addition to the prevailing control vector of steer and throttle response. The use of numerical optimisation to optimise the rear differential hydraulic pressure and the roll stiffness distribution to maximise vehicle performance is demonstrated. The optimisation of the rear differential hydraulic pressure showed a very small improvement in vehicle performance in combined high speed braking and cornering, but highlighted the ability of the differential to affect the cornering behaviour of the vehicle. The optimisation of the roll stiffness distribution research showed that a significant improvement in the lateral acceleration capability of the vehicle could be achieved at all vehicle speeds between 20 and 80m/s, especially in combined braking and cornering. In addition, a parameter sensitivity study around a realistic Formula One vehicle setup was conducted, looking at the sensitivity of vehicle mass, yaw inertia, tyres, centre of gravity location and engine torque to vehicle performance. An investigation into the importance of the path finding calculation is also reported.
Stent Thrombosis in Patients with Atrial Fibrillation Undergoing Coronary Stenting in the AUGUSTUS Trial.

We describe the incidence, timing, and characteristics of stent thrombosis and its consequences in patients with atrial fibrillation (AF) in the AUGUSTUS trial1 who received a coronary stent during their qualifying admission (acute coronary syndrome [ACS] or elective percutaneous coronary intervention [PCI]) and the randomized treatment effects of low-dose aspirin (compared with placebo) and apixaban (compared with vitamin K antagonist [VKA]) on the risk of stent thrombosis. We included patients who received a stent during their qualifying admission. We excluded patients with medically-managed ACS (n=1097) or an unknown qualifying index event (n=19). The protocol was approved by appropriate ethics committees; patients provided written informed consent prior to participation.
Heterogeneous mixtures for synthetic antenna substrates

Heterogeneous mixtures have the potential to be used as synthetic substrates for antenna applications giving the antenna designer new degrees of freedom to control the permittivity and/or permeability in three dimensions such as by a smooth variation of the density of the inclusions, the height of the substrate and the manufacture the whole antenna system in one process. Electromagnetic, fabrication, environmental, time and cost advantages are potential especially when combined with nano-fabrication techniques. Readily available and cheap materials such as Polyethylene and Copper can be used in creating these heterogeneous materials. These advantages have been further explained in this thesis. In this thesis, the research presented is on canonical, numerical and measurement analysis on heterogeneous mixtures that can be used as substrates for microwave applications. It is hypothesised that heterogeneous mixtures can be used to design bespoke artificial dielectric substrates for say, patch antennas. The canonical equations from published literature describing the effective permittivity, e_eff and effective permeability, μ_eff of heterogeneous mixtures have been extensively examined and compared with each other. Several simulations of homogenous and heterogeneous media have been carried out and an extraction/inversion algorithm applied to find their e_eff and μ_eff. Parametric studies have been presented to show how the different variables of the equations and the simulations affect the accuracy of the results. The extracted results from the inversion process showed very good agreement with the known values of the homogenous media. Numerically and canonically computed values of e_eff and μ_eff of various heterogeneous media were shown to have good agreement. The fabrication techniques used in creating the samples used in this research were examined, along with the different measurement methods used in characterising their electromagnetic properties via simulations and measurements. The challenges faced with these measurement methods were explained including the possible sources of error. Patch antennas were used to investigate how the performance of an antenna may be affected by heterogeneous media with metallic inclusions. The performance of the patch antenna was not inhibited by the presence of the metallic inclusions in close proximity. The patch measurement was also used as a measurement technique in determining the e_eff of the samples.
Advanced high pressure engine study for mixed-mode vehicle applications

High pressure liquid rocket engine design, performance, weight, envelope, and operational characteristics were evaluated for a variety of candidate engines for use in mixed-mode, single-stage-to-orbit applications. Propellant property and performance data were obtained for candidate Mode 1 fuels which included: RP-1, RJ-5, hydrazine, monomethyl-hydrazine, and methane. The common oxidizer was liquid oxygen. Oxygen, the candidate Mode 1 fuels, and hydrogen were evaluated as thrust chamber coolants. Oxygen, methane, and hydrogen were found to be the most viable cooling candidates. Water, lithium, and sodium-potassium were also evaluated as auxiliary coolant systems. Water proved to be the best of these, but the system was heavier than those systems which cooled with the engine propellants. Engine weight and envelope parametric data were established for candidate Mode 1, Mode 2, and dual-fuel engines. Delivered engine performance data were also calculated for all candidate Mode 1 and dual-fuel engines.
Urogonimus turdi (Digenea: Leucochloridiidae) from the White’s Thrush, Zoothera aurea, in the Republic of Korea

Avian trematodes, Urogonimus turdi (Digenea: Leucochloridiidae), were collected from the intestine of wild birds, Zoothera aurea, 2013–2017 in the Daejeon Metropolitan City, Korea. The body was ellipsoidal, attenuated and/or round ends, 1,987–2,120 long and 819–831 μm wide. The oral sucker was subterminal, rounded anteriorly, and 308–425×351–432 μm in size; the prepharynx and esophagus were almost lacking; pharynx was well-developed, 142–179×78–170 μm in size; intestine narrow, bifurcating just after pharynx, ascending to the oral sucker before looping posteriorly and terminating near the posterior end; ventral sucker larger, in almost median, 536–673×447–605 μm and approximately 1.5 times larger than oral sucker. A phylogenetic tree constructed with 18S ribosomal RNA showed inter- and intraspecific relationships. Based on these morphological and molecular findings, we report here a U. turdi from White’s thrushes in Korea.
A PROPOSED METHODOLOGY FOR IMPLEMENTING AND EVALUATING A TRUCK PARKING INFORMATION SYSTEM

During the past decade, serious concerns have been raised with respect to increasing truck traffic and the lack of truck parking spaces on highways. The main reason for this is that the inadequacy of large truck parking facilities along interstate highways may consequently lead to rising truck crashes, fatality rates, and other highway safety issues. In addition to building more truck parking facilities along highway corridors, using intelligent transportation system (ITS) technologies, such as a truck parking information system, was regarded as a feasible and effective solution to the problem of truck parking shortage from both traffic engineers' and truck drivers' perspectives. However, there are very limited applications of parking information systems to trucks and along highway corridors. This study proposes a methodology for implementing and evaluating a truck parking information system. The first objective is to develop a prototype truck parking information system for highway corridors, which will help transportation agencies and engineers clarify the high-level concepts and frameworks of such a system. The second objective is to formulate an evaluation methodology to measure the effectiveness of the truck parking information system developed.
