Authors: Naidoo N. , Bühler L. 
Published: June 2017

Introduction: The roles of physiotherapists and chiropractors demon-strate some overlap. Both are members of a multidisciplinary team and contributeto the holistic care of patients. Good understanding of each others’ professionalpractice may lead to good working relationships with effective referrals, inter -disciplinary and multidisciplinary management of patients. Purpose: To investigate the perceptions, attitudes and knowledge of undergraduatephysiotherapy and chiropractic students about each others’ professional roles inclinical practice. Methodology: Data was obtained using a questionnaire with closed and open-ended questions. First and ﬁnal-yearphysiotherapy (n = 72) and chiropractic students (n = 49) participated. Results: First and ﬁnal year physiotherapy students scored 58% and 62% respectively in the “test” on chiropractic;chiropractic students scored 52% and 68% respectively in the test on physiotherapy. Seventy percent of the chiropractic and 14% of the physiotherapy students had visited the practice of other profession. Sixty seven percent of the chiropractic and 38% of the physiotherapy students found it was effective. Forty seven percent chiropractic and 80% physiotherapy students considered physiotherapy and chiropractic to be in direct competition. Sixty six percentof the chiropractic students and 49% of the physiotherapy students expressed the intention of working together withthe other profession. Discussion: The reason for the possible feelings of competitiveness could be because in South A frica there is vastoverlap of practice in both professions; Physiotherapists and chiropractors are seen to use modalities that are similar.This may be viewed as an indication of the importance in deﬁning the roles, scope and characteristics of both physio-therapy and chiropractic.Conclusion: The knowledge of the physiotherapy and chiropractic students is equal, however, chiropractic studentshave more positive perceptions and attitudes towards physiotherapy than physiotherapy students have of chiropractic.
Pain and anxiety experiences of South African adult burn injury patients during physiotherapy management
Authors: Morris L.D. , Louw Q.A. 
Published: June 2017

A dequate management of procedural pain during physiotherapy management plays an important role in building a trusting relationship betweenthe burn victim and the physiotherapist, and in ensuring desirable functional outcomes. However, the burn pain management regimens currently utilized inburn units, primarily consist of traditional pharmacologic analgesics which areassociated with numerous side-effects and alone are often reported as inadequateto alleviate procedural pain, warranting safer and effective adjunct therapies.Prior to the introduction and implementation of adjunct therapies into a developing world, it is imperative that the current situation in a burn unit, in terms of whether or not the pain management regimens in place are adequate, is first assessed, due to cost concerns. The following short report exemplifies the pain and anxiety experiences of a small number of burn injury patients during physiotherapy at the Tygerberg Hospital adult burn unit, South A frica. It was hypothesized that the results of this study would underpin whether adult burn injury patients in a developing countryrequire adjunct therapies during physiotherapy management to supplement traditional pharmacologic analgesics inmanaging their procedural pain and subsequent anxiety.

Em pessoas curadas de hanseníase, as úlceras em membros inferiores representam um desafio aos profissionais, por serem crônicas, infectadas e recorrentes. Esta pesquisa teve como objetivo comparar a ação de uma biomembrana de látex (Biocure®) e de um produto à base de AGE (Dersani®) na microbiota de feridas crônicas infectadas, em pessoas que receberam alta do tratamento para hanseníase. Trata-se de pesquisa realizada no Hospital de Dermatologia Sanitária, de Goiânia (GO), no período de fevereiro a outubro de 2007, na qual participaram 8 pessoas curadas de hanseníase, com 19 feridas infectadas, que foram, alocadas aleatoriamente em grupo A (tratado com Dersani®) e grupo B (tratado com Biocure®). Foram identificados Staphylococcus aureus (50%), Pseudomonas aeruginosa (35,7%), Proteusvulgaris (8,2%), Enterobacter aerogenes (3,3%) e Escherichia coli (2,7%). Os resultados obtidos in vivo sugerem que o Dersani® tenha efeito antimicrobiano positivo sobre Enterobacter aerogenes e o Biocure® sobre Pseudomonas aeruginosa. Os resultados in vitro mostraram ausência de atividade de ambos os produtos sobre os microrganismos isolados das lesões.

AbstractEach summer, large quantities of freshwater and associated dissolved and particulate material are released from the Greenland Ice Sheet (GrIS) into local fjords where they promote local phytoplankton growth. Whether the influx of freshwater and associated micronutrients in glacial meltwater is able to stimulate phytoplankton growth beyond the fjords is disputed, however. Here we show that the arrival of freshwater discharge from outlet glaciers from both southeast and southwest GrIS coincides with large‐scale blooms in the Labrador Sea that extend over 300 km from the coast during summer. This summer bloom develops about a week after the arrival of glacial meltwater in early July and persists until the input of glacial meltwater slows in August or September, accounting for ~40% of annual net primary production for the area. In view of the absence of a significant change in the depth of the mixed layer associated with the arrival of glacial meltwater to the Labrador Sea, we suggest that the increase in phytoplankton biomass and productivity in summer is likely driven by a greater nutrient supply (most likely iron). Our results highlight that the ecological impact of meltwater from the GrIS likely extends far beyond the boundaries of the local fjords, encompassing much of the eastern Labrador Sea. Such impacts may increase if melting of the GrIS accelerates as predicted.

AbstractBioactive glasses (BAGs) are highly interesting materials for bone regeneration applications in orthopedic and dental defects. It is quite well known that ionic release from BAGs influences cell behavior and function. Mindful of the clinical scenario, we hypothesized that local cell populations might additionally physically interact with the implanted BAG particles and respond differently than to just the ionic stimuli. We therefore studied the biological effect of two BAG types (45S5 and 1393) applied to human mesenchymal stromal cells (hMSCs) in three distinct presentation modes: (a) direct contact; and to dissolution products in (b) 2D, and (c) 3D culture. We furthermore investigated how the dose‐dependence of these BAG particles, in concentrations ranging from 0.1 to 2.5 w/v %, influenced hMSC metabolic activity, proliferation, and cell spreading. These cellular functions were significantly hampered when hMSCs were exposed to high concentrations of either glasses, but the effects were more pronounced in the 45S5 groups and when the cells were in direct contact with the BAGs. Furthermore the biological effect of 1393 BAG outperformed that of 45S5 BAG in all tested presentation modes. These outcomes highlight the importance of investigating cell–BAG interactions in experimental set‐ups that recapitulate host cell interactions with BAG particles. © 2017 Wiley Periodicals, Inc.

Published: June 2017

AbstractThe investigations of new aluminum‐enriched RDX‐based composites belonging to the thermobaric and enhanced blast explosive formulations were undertaken. In a semi‐closed bunker, the blast wave and the thermal characteristics of pressed and layered charges made from the composites are determined. The study includes the blast wave history registrations as well as the determination of the overpressure peaks and the specific impulses of the incident blast wave. The total impulses have been estimated for a period of 60 ms. Since the composites are supposed to be volumetric, the explosion light outputs and the fireball temperatures were also investigated. The results obtained for the composite charges were compared with the blast performances and fireball temperatures of TNT and phlegmatized RDX charges of the same mass. Also differences between the pressed and the layered composite charges prepared from the same composites were observed and explained. The effect of the aluminum particle size was checked. Discussion of the results and conclusions about the aluminum combustions during the explosions of such charges were presented.

Published: June 2017

AbstractThis paper describes a 3D vision system for robotic harvesting of broccoli using low‐cost RGB‐D sensors, which was developed and evaluated using sensory data collected under real‐world field conditions in both the UK and Spain. The presented method addresses the tasks of detecting mature broccoli heads in the field and providing their 3D locations relative to the vehicle. The paper evaluates different 3D features, machine learning, and temporal filtering methods for detection of broccoli heads. Our experiments show that a combination of Viewpoint Feature Histograms, Support Vector Machine classifier, and a temporal filter to track the detected heads results in a system that detects broccoli heads with high precision. We also show that the temporal filtering can be used to generate a 3D map of the broccoli head positions in the field. Additionally, we present methods for automatically estimating the size of the broccoli heads, to determine when a head is ready for harvest. All of the methods were evaluated using ground‐truth data from both the UK and Spain, which we also make available to the research community for subsequent algorithm development and result comparison. Cross‐validation of the system trained on the UK dataset on the Spanish dataset, and vice versa, indicated good generalization capabilities of the system, confirming the strong potential of low‐cost 3D imaging for commercial broccoli harvesting.

Published: June 2017

AbstractDespite significant development in the area, efficient sensing of fluoride ions in aqueous media remained a serious challenge. In this communication we report the design and synthesis of two eco‐friendly carbohydrate‐based probes for the fluorimetric sensing of fluoride ions. The novel probes are fully characterized with NMR, UV‐Vis, FTIR and MALDI‐TOF. The probes showed selective detection of fluoride anion within the permissible limit set by WHO. The organic cellulose nanocomposite (CNC) based probe showed the lowest detection limit among other carbohydrate‐based probes for the detection of fluoride anion. In addition to the excellent sensitivity, these probes are particularly attractive for their bio‐availability and non‐toxic nature.
Single-cell entropy for accurate estimation of differentiation potency from a cell’s transcriptome
Authors: Teschendorff Andrew E. , Enver Tariq 
Published: June 2017

AbstractThe ability to quantify differentiation potential of single cells is a task of critical importance. Here we demonstrate, using over 7,000 single-cell RNA-Seq profiles, that differentiation potency of a single cell can be approximated by computing the signalling promiscuity, or entropy, of a cell’s transcriptome in the context of an interaction network, without the need for feature selection. We show that signalling entropy provides a more accurate and robust potency estimate than other entropy-based measures, driven in part by a subtle positive correlation between the transcriptome and connectome. Signalling entropy identifies known cell subpopulations of varying potency and drug resistant cancer stem-cell phenotypes, including those derived from circulating tumour cells. It further reveals that expression heterogeneity within single-cell populations is regulated. In summary, signalling entropy allows in silico estimation of the differentiation potency and plasticity of single cells and bulk samples, providing a means to identify normal and cancer stem-cell phenotypes.

AbstractTumor local invasion is the first step of metastasis cascade which remains the key obstacle for cancer therapy. Collective cell migration plays a critical role in tumor invading into surrounding tissues. In vitro assays fail to assess collective invasion in a real time manner. Herein we aim to develop a three-dimensional (3D) microfluidic cell invasion model to determine the dynamic process. In this model, collective invasion of breast cancer cells is induced by the concentration gradient of fetal bovine serum. We find that breast cancer cells adopt a collective movement rather than a random manner when the cells invade into extracellular matrix. The leading cells in the collective movement exhibit an increased expression of an Aurora kinase family protein - AURKA compared with the follower cells. Inhibition of AURKA kinase activity by VX680 or AKI603 significantly reduces the phosphorylation of ERK1/2 (Thr202/Tyr204) and collective cohort formation. Together, our study illustrates that AURKA acts as a potential therapeutic target for suppressing the process of tumor collective invasion. The 3D microfluidic cell invasion model is a reliable, measurable and dynamic platform for exploring potential drugs to inhibit tumor collective invasion.

Published: June 2017

AbstractNanoparticles (NPs) have a significant impact on the environment and living organisms. The influence of NPs on plants is intensively studied and most of the data indicate that NPs can penetrate into plants. The studies presented here were performed on the roots of Hordeum vulgare L. seedlings using neutral-charge gold nanoparticles (AuNPs) of different sizes. In contrast to the majority of the published data, the results presented here showed that during the culture period, AuNPs: 1/did not enter the root regardless of their size and concentration, 2/that are applied directly into the cells of a root do not move into neighbouring cells. The results that were obtained indicate that in order to extend our knowledge about the mechanisms of the interactions between NPs and plants, further studies including, among others, on different species and a variety of growth conditions are needed.

Published: June 2017

AbstractThe Indian Ocean has long been a hub of interacting human populations. Following land- and sea-based routes, trade drove cultural contacts between far-distant ethnic groups in Asia, India, the Middle East and Africa, creating one of the world’s first proto-globalized environments. However, the extent to which population mixing was mediated by trade is poorly understood. Reconstructing admixture times from genomic data in 3,006 individuals from 187 regional populations reveals a close association between bouts of human migration and trade volumes during the last 2,000 years across the Indian Ocean trading system. Temporal oscillations in trading activity match phases of contraction and expansion in migration, with high water marks following the expansion of the Silk Roads in the 5th century AD, the rise of maritime routes in the 11th century and a drastic restructuring of the trade network following the arrival of Europeans in the 16th century. The economic fluxes of the Indian Ocean trade network therefore directly shaped exchanges of genes, in addition to goods and concepts.

Published: June 2017

AbstractMolecular mechanisms regulating preterm birth (PTB)-associated cervical remodeling remain unclear. Prior work demonstrated an altered miRNA profile, with significant increases in miR-143 and miR-145, in cervical cells of women destined to have a PTB. The study objective was to determine the effect of miR-143 and miR-145 on the cervical epithelial barrier and to elucidate the mechanisms by which these miRNAs modify cervical epithelial cell function. Ectocervical and endocervical cells transfected with miR-negative control, miR-143 or miR-145 were used in cell permeability and flow cytometry assays for apoptosis and proliferation. miR-143 and miR-145 target genes associated with cell adhesion, apoptosis and proliferation were measured. Epithelial cell permeability was increased in miR-143 and miR-145 transfected cervical epithelial cells. Cell adhesion genes, JAM-A and FSCN1, were downregulated with overexpression of miR-143 and miR-145. miR-143 and miR-145 transfection decreased cervical cell number by increasing apoptosis and decreasing cell proliferation through initiation of cell cycle arrest. Apoptosis genes, BCL2 and BIRC5, and proliferation genes, CDK1 and CCND2, were repressed by miR-143 and miR-145. These findings suggest that miR-143 and miR-145 play a significant role in cervical epithelial barrier breakdown through diverse mechanisms and could contribute to premature cervical remodeling associated with PTB.
Autologous Fat Grafting Combined with Facelifting
Authors: Tzikas Thomas 
Published: June 2017

AbstractThere are multiple factors contributing to facial aging. Rejuvenation of the aging face, therefore, requires a multimodal approach to attain an overall natural and uniform result that is long lasting. Fat grafting has become a very important method for restoring facial soft-tissue atrophy, while facelifting procedures address the ptosis and descent of facial and neck tissue. These modalities performed together offer the patient a comprehensive approach to attain a more attractive and youthful facial appearance.

Published: June 2017

AbstractAmong aesthetic surgery procedures, rhinoplasty is one of the most common. Preoperative simulations have become increasingly commonplace through the recent years along with a controversy regarding their use. Although capable of building a solid rapport between the surgeon and the patient by visualizing the end result, it can also prove to be a liability for a surgeon who is not confident about delivering the result which has been put on screen. The objective of this study is to evaluate the outlook of the surgeons and patients on preoperative simulations. Plastic surgeons who perform rhinoplasty and individuals who consider rhinoplasty were surveyed via an online questionnaire system. Their opinions about the practice of simulation were questioned and they were asked to distinguish between simulated and actual postoperative results. Statistical analyses were performed using SPSS software. Major factors influencing the decision-making process of patients were the availability of preoperative simulation, being shown appealing results of the surgeon's previous work and a personal reference from a patient with an appealing result. Within the health care professionals, it has been observed that experienced surgeons are more confident about using simulations, while inexperienced ones are daunted by being bound with a visual contract (p < 0.05). However, it has been noted that the preference of withholding the simulation or providing a copy to the patient was similar in all experience levels (p > 0.05). In conclusion, our findings suggest that the patients' self-consciousness regarding preoperative simulations seem to grow faster than the surgeons' confidence in their use. Level of evidence is Level V.
