The modulatory effect of Schisandra chinensis seed extract on cisplatin induced cytotoxicity and cell proliferation inhibition in human osteosarcoma cells

Aim: To evaluate the effect of Schisandra chinensis seed extract (used in Chinese medicine) on cisplatininduced cytotoxicity in osteosarcoma cells. Methods: MTT and caspase assays were used to determine the apoptotic potential of cisplatin and Schisandra chinensis seed extract on Human Osteosarcoma Cells (HOS). The effect of exposure to cisplatin and Schisandra chinensis extract on the expression of caspase 3 was evaluated. The sensitivity of osteosarcoma cells to cisplatin and the expression of phosphor glycoprotein and cisplatin separately and in combination with Schisandra chinensis extract were assessed. Results: The results of the study indicate cisplatin and seed extract of Schisandra chinensis induced apoptosis in human osteosarcoma cells. The combination of cisplatin and seed extract produced a significant increase in the apoptosis level in osteosarcoma cells. Caspase activation increased significantly on treatment with cisplatin and of Schisandra chinensis seed extract. The seed extract increased the cisplatin sensitivity as well as the expression of phosphoglycoprotein. Conclusion: Schisandra chinensis seed extract ameliorates cisplatin-induced cytotoxicity through apoptosis and increases sensitivity by increasing the expression of p-glycoprotein.
Circular economy in construction: current awareness, challenges and enablers

The application of the concept of circular economy thinking in construction, which is in its infancy, has been largely limited to construction waste minimisation and recycling. Little research on circular economy from a systems perspective including how new business models might enable materials to retain high residual values has been undertaken. Utilising the results from a survey and a follow-up workshop, this paper provides an analysis of an industrywide perspective of circular economy awareness, challenges and enablers. The survey results indicate that while there is industrywide awareness of the concept, clients, designers and subcontractors are the least informed and this is a key challenge for greater adoption. The absence of incentives to design products and buildings for disassembly and reuse at their end of life is a significant challenge. To encourage greater implementation of circular economy principles throughout the supply chain, a clear economic case is paramount, supported by metrics, tool.
Effect of Tai Chi Chuan training on main performance during dance movements

Purpose: Tai Chi Chuan (TCC) training is usually considered as useful training methods for improving postural stability during human movement performance. Whether the jumps, spin, and balance required in dance movements can be reinforced through TCC training is not certain. This study was to investigate the influence of 8-week TCC training on the selected dance movements. Method: A total of 16 senior high school dancers participated in this study (8 in the training group and 8 in the control group). A force platform and a 3D motion analysis system were used to analyze the movements of saute (jump), passe (balance), and pirouette en dehors (spin). Results: The results showed that the training group demonstrated greater improvement than did the control group in the following areas: (a) The maximum lower extremity push-off force and air hang time during saute jumps; (b) The center of gravity (COG) shift distance and shift speed during passe balance; (c) The working leg hip joint external rotation angle, the supporting leg plantar flexion angle, and the COG shift distance during pirouette en dehors spin. Conclusion: TCC training facilitated reinforcing dance movements and may be used as part of physical training program for improving dance performance.
Regionality, innovation policy and peripheral regions in Finland, Sweden and Norway

This article discusses how the national innovation policies in Finland, Sweden and Norway consider regionality, especially peripheral regions. This aspect is of interest considering how these three countries perform well in international competition while having substantial differences between different regions in terms of their economical development. The northernmost parts of Finland, Sweden and Norway are raised as examples as they are especially challenging areas in the context of innovation activities. As a theoretical background I introduce the concepts of innovation systems and innovation policy and define the challenges involved when implementing innovation policies in peripheral regions. The study is realised by analysing 20 innovation policy documents: ten from Finland, six from Sweden and four from Norway. I use qualitative content analysis as a research method. This investigation shows that, in spite of the importance of regions in innovation activities, national innovation policies in the research countries do not consider regionality, or, more specifically, the less-favoured regions. Meanwhile, regional innovation systems, especially institutes of higher education, are seen as important for the economic development and competitiveness of the countries and their national innovation systems.
The Effect of a Community-Based Group Exercise in Chronic Stroke

Community-based group exercise programs for people with chronic stroke are relatively uncommon in Korea. In addition, it is currently not known whether a community-based group exercise program is effective or not. The purpose of this study was to evaluate an 8 week community-based functional exercise program for its effects on balance performance and occupational performance in persons with chronic stroke. Twenty-five community-dwelling individuals with stroke participated in this program. Outcome of the program was assessed by the Berg Balance Scale and the Canadian Occupational Performance Measure (COPM). The functional exercise program lasted for eight weeks, with a 1-hour program twice per week and it consisted of mobility, stability, balance, functional strength, and gait training. The subjects were trained by one physical therapist but were under one-to-one supervision from students. The data of sixteen individuals who scored more than 24 on the Mini-Mental State Examination (MMSE) were analyzed. There was a significant effect both in terms of the COPM Performance Score & the Satisfaction Score (p=.002) and with the Berg Balance Score (p=.001). It was found that a short-term community-based exercise program could improve both performance of activities and balance. Further, all subjects reported that they were satisfied with this program.
Point defect movement and annealing in collision cascades

The effect of collision cascades on preexisting point defects in crystalline materials was studied by simulating 5 keV collision cascades in gold, copper, aluminum, platinum, and silicon. The results indicate that collision cascades do not significantly affect interstitials or vacancies outside the liquid core of the cascade, although in the fcc metals the heating of the crystal due to the cascade causes some thermal migration of the interstitials. Within the liquid cascade core, both interstitials and vacancies move towards the center of the molten region when it resolidifies and recombine or cluster there. At elevated temperatures, random jumps of interstitials during the thermal-spike phase can cause significant additional trapping of interstitials in the liquid. In contrast to the annealing effects of preexisting damage in the fcc metals, in silicon the amount of new damage created by a cascade is roughly independent of the number of initial point defects. The difference is attributed to the nature of the bonding in the materials. {copyright} {ital 1997} {ital The American Physical Society}
Laboratory study of the effects of leek lectin (APA) in transgenic tobacco plants on the development of cotton leafworm Spodoptera littoralis (Lepidoptera: Noctuidae)

Transgenic tobacco plants expressing the Allium porrum L. (leek) agglutinin (called APA) under the control of the 35S constitutive promoter were tested for their insecticidal activity against the cotton leafworm, Spodoptera littoralis (Lepidoptera: Noc- tuidae). Southern blot and PCR analysis confirmed that the APA gene was integrated into the plant genome. Northern and Western blots as well as semi-quantitative agglutination assays revealed lectin expression at various levels in the transgenic lines. Bio- chemical analyses indicated that the recombinant APA has the same molecular structure as the native lectin. Native and recombinant lectin have the same N-terminal amino acid sequence. Bioassays using detached leaves from transgenic tobacco plants demonstrated that the ectopically expressed APA significantly (p < 0.05) reduced the weight gain of 2nd-instar larvae of S. littoralis. This inhibi- tory effect was observed throughout the experiment and on day 11 the caterpillars fed on transgenic tobacco leaves were 25-30% lighter in weight than the control caterpillars fed on wild type plants. In addition the lectin retarded the development of the larvae and metamorphosis, reduced pupal weight and increased mortality rate. These findings suggest that APA is a suitable insect resis- tance protein for integrating into plant genomes for controlling S. littoralis.
Procalcitonin is not a marker of sterile inflammation in dogs after ovariohysterectomy

Abstract CRP and WBC are the most widely used markers of inflammation in veterinary clinical diagnosis. Also, PCT is a specific APP marker of bacterial diseases in humans. This study evaluated the levels of PCT, CRP and WBC during postoperative monitoring of bitches undergoing ovariohysterectomy. Thirteen adult clinically healthy female crossbreed dogs aged between 7-24 months were used in the study. Ovariohysterectomy was performed via medial laparotomy using routine procedures. Blood samples were collected from the cephalic vein at 1, 4 and 7 days after surgery (post-op period). Mean serum concentration of PCT, CRP and WBC levels were increased after the surgery. CRP concentrations and WBC counts were increased significantly (p<0.001) on the first day after the operation and decreased to basal values. However, the PCT rise was not significant. CRP and WBC levels increased rapidly and decreased to normal values in dogs with ovariohysterectomy. CRP and WBC may be of help to determine the possible postoperative complications. Besides, aseptic surgical trauma did not affect PCT levels in dogs. Future studies are needed on canine PCT response focusing on specific bacterial infections.
Impact of Forest Road Construction on Topsoil
Erosion and Hydro-Physical Soil Properties
in a Semi-Arid Mountainous Ecosystem
in Turkey

This study aimed at pointing out the environmental importance of road construction in a semi-arid high mountainous area on soil erosion and some important soil properties throughout the forest road. In total 60 soil samples in both forest and open area were collected from topsoil (0-20 cm) of a cut slope, fill slope, and control points along with a forest road route. The soil properties were determined in the laboratory and the soil loss amounts were determined by way of an Allgemeine Boden Abtrags Gleichung (ABAG) simulation model. As a result, the road construction phase significantly changed (p<0.001) the soil erosion trend. Annual soil loss amounts (t/ha/yr.) determined cut slope > fill slope > control in both forest and open areas. Consequently, road construction efforts significantly affected topsoil loss and some soil properties such as organic matter, available water-holding capacity, and bulk density. According to the created scenario, under the same slope (68.72%) and slope length (3.26 m) conditions, the highest soil loss trend was in cut slope, which was significantly different (p<0.001) from fill slope and control in forested and open areas.
The Possibility of Disposing of Spent Coffee Ground With Energy Recycling

The current policy of waste management requires, above all, a gradual reduction of waste amount and, to a larger extent, forces us to seek new methods of waste disposal. Recycling the energy contained in biomass waste is a more and more universally applied method of thermal converting. Biomass combustion allows saving fossil fuels which fits into sustainable development. This paper checks the possibility of using spent coffee ground (SCG) in energy recycling using a combustion process. This particular biomass type up to now has not been widely examined, which inclines to consider its usage as a potential additive to alternative fuels. In the study, we examined the quality of fuel, which was in a form of briquette, made of beech shavings with 10 and 25% of post-exploitation waste obtained during the process of coffee infusion. This waste, if fresh, is distinguished by its high hydration. However, after drying it may constitute a valuable additive to alternative fuels. It increases the calorific value of fuel and reduces briquettes’ hardness what contributes to reducing resistance of conveying screw in stoves.
Performance investigation of low power radio duty cycling MAC for resource constrained WSN

Wireless Sensor Networks (WSN) are the corner stone of next generation communication networks. The OSI Layer 2 and Layer 3 communication technologies of the WSN are the important aspects in communication and networking research. The protocols and standards of WSN in different layers are already well defined. In this article, we evaluate the Layer 2 mechanisms which meet the special demands of WSNs for resource constrained applications. Large number of WSN devices need to be deployed in a typical environmental monitoring use cases. In this work we consider a use case of sensors and actuators in a small geographical region. For this a short range communication technology such as IEEE 802.15. 4 is considered. Various type of sensors are deployed in the same region, in this cases effective MAC mechanism is required to effectively allocate the channel resource among these devices. The main concentration of this article is about the energy consumption of WSN devices. As the devices and network is resource constrained, energy efficient hardware’s, communication networking protocols and suitable software implementations are required. As far as the energy efficient protocols are considered MAC mechanisms is one of the very important processes, where suitable energy efficient mechanisms need to be selected. In the recent literatures showed that Contiki MAC is one of the suitable MAC layer implementation with dedicated Radio Duty Cycling Layer (RDC) which conserves the WSN nodes battery power. In this article we analyze the state of the art Layer 2 mechanisms for WSN in environmental monitoring use case, by a theoretical analysis and simulation based experiments.
Using Multibody Dynamics for the Stability Assessment of a New Rotor Test Rig

The secure entry into service of a new rotor test rig requires the assessment of the dynamic and aeroelastic rotor stability. To this end, a multibody dynamics based numerical model was developed and coupled with an unsteady aerodynamic model based on Wagner's function and related enhancements for the general motion of an airfoil section considering heave and pitch motion. The simulation model uses modelling techniques for the setup of a linearized model and allows both, the investigation of ground resonance and flutter for the rig with clamped and articulated rotor blades in frequency domain. With respect to ground resonance, the dynamic examination of the two- and four-bladed rotor configurations shows a mechanically stable behaviour for the clamped and articulated rotor blades with lead-lag hinge in the planned rotor speed range up to 65 Hz. The aeroelastic assessment shows a damped behaviour for the configurations with clamped rotor blades, whilst the articulated rotor with lead-lag hinge is unstable beyond rotational speeds of 25 Hz for the two-bladed rotor and requires additional damping measures.
Study of GaN light-emitting diodes fabricated by laser lift-off technique

The fabrication process and performance characteristics of the laser lift-off (LLO) GaN light-emitting diodes (LEDs) were investigated. The LLO-GaN LEDs were fabricated by lifting off the GaN LED wafer structure grown on the original sapphire substrate by a KrF excimer laser at 248 nm wavelength with the laser fluence of 0.6 J/cm2 and transferring it onto a Cu substrate. The LLO-GaN LEDs on Cu show a nearly four-fold increase in the light output power over the regular LLO-LEDs on the sapphire substrate. High operation current up to 400 mA for the LLO-LEDs on Cu was also demonstrated. Based on the emission wavelength shift with the operating current data, the LLO-LEDs on Cu show an estimated improvement of heat dissipation capacities by nearly four times over the light-emitting devices on sapphire substrate. The LLO process should be applicable to other GaN-based LEDs in particular for those high light output power and high operation current devices.
Large river floodplain as a natural laboratory: non-native macroinvertebrates benefit from elevated temperatures

Water temperature is known to influence individual animal metabolism, development, and reproduction. However, in situ studies aiming to demonstrate the link between water temperature and community structure in complex ecosystems such as large river floodplains are still rare. In particular, we have little indication about how an increase in temperature affects the density of native and invasive species within a community. Large river floodplains cover a varied range of environmental conditions, are rich in species, and therefore potentially useful ecosystems to study the effect of water temperature at the community level. Moreover, as freshwater communities are increasingly impacted by global warming and biological invasions, an improved understanding of the possible interaction between these drivers would be beneficial. First, we studied during two years the thermal heterogeneity of 36 sites in a large river (Rhone) floodplain. Second, we compared the thermal regimes of sites having different levels of hydrological connectivity with the main river channel. Third, we studied the combined and separated effects of the thermal regime and the hydrological connectivity on the presence and densities of native and non-native species of macroinvertebrates. The studied large river floodplain covered a wide range of thermal regimes, with some sites displaying a yearlong constant temperature of about 10°C, whereas others experienced thermal amplitude of over 25°C. The thermal regime was independent of the level of hydrological connectivity of the sites. The increase in hydrological connectivity had a significant and positive effect on the richness of non-native species within sites. The thermal regime had a positive influence on the density of non-native species but no effect on the total density of native taxa within communities. This study showed that large river floodplains possess a wide range of thermal conditions and that the increase in water temperature can have a positive influence on the presence of non-native populations of macroinvertebrates. This study provides a first set of empirical results to establish models predicting the effect of increasing temperatures on the establishment of non-native and native species in a complex ecosystem and underline the problem of biological invasions under climate change.
Post-Traumatic Stress Disorder and Anger in Migraine Patients

Post-traumatic stress disorder and anger in migraine patients Objective: In recent studies, a relationship between migraine headaches and post-traumatic stress disorder (PTSD) has been suggested. The clinicians in most of these studies have not diagnosed PTSD; the evaluation has been carried out using screening scales. It has also been asserted that there is a relation between anger and migraine and other chronic painful disorders. This study aimed to search the prevalence of clinically diagnosed post-traumatic stress disorder (PTSD) among migraine patients and the relationship with anger. Method: Sixty consecutive migraine patients directed from neurology clinic and 60 healthy controls having similar features constituted the sample of this study. SCID-I/CV PTSD module and clinician administered posttraumatic stress disorder scale (CAPS) implemented by the clinician were administered to the sample. The sample also filled in the socio-demographic data form and Spielberg’s State-Trait Anger-Anger Expression Scale (STAXI). Results: Seventeen persons (28%) in the migraine group and 5 persons (8.3%) in the control group were diagnosed with PTSD. In the migraine group, PTSD was found at a statistically significantly higher level. The trait anger and anger in subscale scores in the migraine group were found statistically significantly higher compared to the control group. In the migraine group, the anger out subscale mean score was statistically significantly higher in the ones with PSTD than the ones without it. A positive correlation was detected between the scores of trait anger and CAPS and a negative correlation between the scores of anger control and CAPS. Conclusion: In migraine patients, PTSD, trait anger and internal anger are higher compared to the healthy ones. In migraine patients diagnosed with PTSD, the external anger has increased. It may be suggested to seek for the trauma experiences in migraine patients and search the efficiency of trauma and anger directed therapies.
The Application of Improved Tracking-differentiator Filter in ECG Data

Denoising is very important in signal processing. Electrocardiogram (ECG) data always contains 50 or 60 Hz power line interferences (PLI), PLI may affect the detection of P wave, QRS complex and T wave. So the pre-processing of ECG data is necessary. In order to remove PLI, in this paper, we use two improved tracking-differentiator filters (ITDFs), which are signed ITDF1 and ITDF2 respectively. The simulation results for ECG signals obtained from MIT-BIH database indicate that ITDFs are good methods for filtering noises, and ITDF2 does better than ITDF1.
Micro job design: Affective reactions to real-time task characteristics

Most job design research assesses the effects of typical job characteristics on long term person level outcomes. We suggest that it is also worth studying short term affective reactions to momentary variations in task characteristics over the working day; what we will call “micro job design. ” While there may be across-theboard positive (or negative) reactions to some momentary task characteristics, we also hypothesise that there will be individual differences in reactions to task characteristics. In two experience sampling studies we demonstrate that, 1. High but not low growth need strength employees respond to increases in task demand with increasing positive emotions, and 2. High learning or low avoid goal orientation employees react to increasing task autonomy with larger increases in the experience of flow compared to low learning or high avoid goal orientation employees.
