Basically every individual has a concept about himself. The concept which has been ingrained in each individual, would influence the behavior of that individuals in various aspects of their life including in facing the problems. Only a little of the students are able to solve the problem well. Sometimes to keep themselves right in a problem, they “form” defense mechanism. This research was conducted to reveal the correlation between self concept and defense mechanism of guidance and counseling students of IAIN Bukittinggi. The population was the entire of guidance and counseling students that concist of 452 students, and 102 samples. The data was collected by using questionnaire that was processed using product moment technique in SPSS 21.0 version. The result shown that there is a significant correlation between self-concept and defense mechanism in facing the problem with the r calculated was 0.433. The strength of the correlation between self-concept and defense mechanism of BK students of IAIN Bukittinggi are at moderate or sufficient.

AbstractThe borothermal reduction of metal oxides in molten salts is reported as a general method towards transition metal monoboride nanopowders. Crystallized CrB powders with average particle sizes of 40 – 50 nm were synthesized at a lowest temperature of 800 °C. The presence of molten salts greatly inhibited the formation of impurities and the grain growth of CrB particles. NbB and TaB powders were also successfully synthesized by the same method at 1 000 °C and 1 100 °C, respectively.

OBJECTIVEThe risk of injury of the cochlear nerve during angle (CPA) surgery is high. Granulocyte colony–stimulating factor (G-CSF) has been found in various experimental models of peripheral and CNS injury to have a neuroprotective effect by inhibiting apoptosis and inflammation. However, to the authors' knowledge, the influence of G-CSF on cochlear nerve regeneration has not been reported. This study investigated the neuroprotective effect of G-CSF after a partial cochlear nerve lesion in rats.METHODSA lesion of the right cochlear nerve in adult male Sprague-Dawley rats was created using a water-jet dissector with a pressure of 8 bar. In the first group (G-CSF-post), G-CSF was administrated on Days 1, 3, and 5 after the surgery. The second group (G-CSF-pre/post) was treated with G-CSF 1 day before and 1, 3, and 5 days after applying the nerve injury. The control group received sodium chloride after nerve injury at the various time points. Brainstem auditory evoked potentials (BAEPs) were measured directly before and after nerve injury and on Days 1 and 7 to evaluate the acoustic function of the cochlear nerve. The animals were sacrificed 1 week after the operation, and their brains were fixed in formalin. Nissl staining of the cochlear nuclei was performed, and histological sections were analyzed with a light microscope and an image-processing program. The numbers of neurons in the cochlear nuclei were assessed.RESULTSThe values for Waves 2 and 4 of the BAEPs decreased abruptly in all 3 groups in the direct postoperative measurement. Although the amplitude in the control group did not recover, it increased in both treatment groups. According to 2-way ANOVA, groups treated with G-CSF had a significant increase in BAEP Wave II amplitudes on the right side (p = 0.0401) after the applied cochlear nerve injury. With respect to Wave IV, a trend toward better recovery in the G-CSF groups was found, but this difference did not reach statistical significance. In the histological analysis, higher numbers of neurons were found in the G-CSF groups. In the statistical analysis, the difference in the numbers of neurons between the control and G-CSF-post groups reached significance (p = 0.0086). The difference in the numbers of neurons between the control and G-CSF-pre/post groups and between the G-CSF-post and G-CSF-pre/post groups did not reach statistical significance.CONCLUSIONSThe use of G-CSF improved the function of the eighth cranial nerve and protected cochlear nucleus cells from destruction after a controlled partial injury of the nerve. These findings might be relevant for surgery that involves CPA tumors. The use of G-CSF in patients with a lesion in the CPA might improve postoperative outcomes.

Misalignments of the CFA Franc and Influence of the Anchor Currency.
The euro’s appreciation in the 2000s has revived the debate on the future of the CFA franc. In this paper, we study howthe economic fundamentals of the CFA zone interacted with the evolution of the anchor currency over the 1980-2009 period to form the CFA franc’s real effective exchange rate. We assess the respective impacts of fundamentals and euro trends on CFA franc misalignments and hence on the price competitiveness of the region and its constituent countries. Relying on recent panel cointegration methods, we identify three episodes in which the anchor currency and CFA-zone fundamentals have had relatively differing effects.

Summary
Background: The functional connectivity and structural proximity of elements of the language and motor systems result in frequent co-morbidity post brain injury. Although rehabilitation services are becoming increasingly multidisciplinary and “integrated”, treatment for language and motor functions often occurs in isolation. Thus, behavioural therapies which promote neural reorganisation do not reflect the high inter-system connectivity of the neurologically intact brain. As such, there is a pressing need for rehabilitation tools which better reflect and target the impaired cognitive networks.
Objectives: The objective of this research is to develop a combined high dosage therapy tool for language and motor rehabilitation. The rehabilitation therapy tool developed, MaLT (Motor and Language Therapy), comprises a suite of computer games targeting both language and motor therapy that use the Kinect sensor as an interaction device. The games developed are intended for use in the home environment over prolonged periods of time. In order to track patients’ engagement with the games and their rehabilitation progress, the game records patient performance data for the therapist to interrogate.
Methods: MaLT incorporates Kinect-based games, a database of objects and language parameters, and a reporting tool for therapists. Games have been developed that target four major language therapy tasks involving single word comprehension, initial phoneme identification, rhyme identification and a naming task. These tasks have 8 levels each increasing in difficulty. A database of 750 objects is used to programmatically generate appropriate questions for the game, providing both targeted therapy and unique game-play every time. The design of the games has been informed by therapists and by discussions with a Public Patient Involvement (PPI) group.
Results: Pilot MaLT trials have been conducted with three stroke survivors for the duration of 6 to 8 weeks. Patients’ performance is monitored through MaLT’s reporting facility presented as graphs plotted from patient game data. Performance indicators include reaction time, accuracy, number of incorrect responses and hand use. The resultant games have also been tested by the PPI with a positive response and further suggestions for future modifications made.
Conclusion: MaLT provides a tool that innovatively combines motor and language therapy for high dosage rehabilitation in the home. It has demonstrated that motion sensor technology can be successfully combined with a language therapy task to target both upper limb and linguistic impairment in patients following brain injury. The initial studies on stroke survivors have demonstrated that the combined therapy approach is viable and the outputs of this study will inform planned larger scale future trials.
Do modelled or satellite-based estimates of surface solar irradiance accurately describe its temporal variability?

Published: February 2017

Abstract. This study investigates the characteristic time-scales of variability found in long-term time-series of daily means of estimates of surface solar irradiance (SSI). The study is performed at various levels to better understand the causes of variability in the SSI. First, the variability of the solar irradiance at the top of the atmosphere is scrutinized. Then, estimates of the SSI in cloud-free conditions as provided by the McClear model are dealt with, in order to reveal the influence of the clear atmosphere (aerosols, water vapour, etc.). Lastly, the role of clouds on variability is inferred by the analysis of in-situ measurements. A description of how the atmosphere affects SSI variability is thus obtained on a time-scale basis. The analysis is also performed with estimates of the SSI provided by the satellite-derived HelioClim-3 database and by two numerical weather re-analyses: ERA-Interim and MERRA2. It is found that HelioClim-3 estimates render an accurate picture of the variability found in ground measurements, not only globally, but also with respect to individual characteristic time-scales. On the contrary, the variability found in re-analyses correlates poorly with all scales of ground measurements variability.

Purpose In recent years, a large variety of medical devices has become available. Every device must be efficient, safe and cost effective, but it is not enough to use it properly without considering the environment in which it will be employed. We applied this kind of analysis to subcutaneously anchored sutureless devices (SAS). Methods This is a one-center prospective observational study on safety, effectiveness and cost effectiveness of an SAS device (SecurAcath, Interrad) for securement of peripherally inserted central catheter (PICC) in 30 adult cancer patients with treatment expected to be >60 days. Results During 4963 catheter days and after 709 dressing changes (documented by 373 pictures), the use of SAS was associated with no episode of PICC dislodgement and a lower incidence of complications if compared to traditional securement devices. Insertion, management and removal of SAS were not associated with an increased pain perception by the patients. Cost effectiveness was particularly evident for long dwelling PICCs. Conclusions Our study suggests that SAS is a highly effective and cost-effective method for securement of medium- to long-term PICCs with expected duration longer than 30 days. The introduction of SAS had a positive impact on our healthcare organization.

There is increasing evidence that circular RNA (circRNA) are involved in cancer development, but the regulation and function of human circRNA remain largely unknown. In this study, we demonstrated that ZKSCAN1, a zinc finger family gene, is expressed in both linear and circular (circZKSCAN1) forms of RNA in human hepatocellular carcinoma (HCC) tissues and cell lines. Here, we analyzed a cohort of 102 patients and found that expression of both ZKSCAN1mRNA and circZKSCAN1 was significantly lower (P < 0.05) in the HCC samples compared with that in matched adjacent nontumorous tissues by reverse transcription PCR (RT‐PCR). The low expression level of ZKSCAN1 was only associated with tumor size (P = 0.032), while the cirZKSCAN1 levels varied in patients with different tumor numbers (P < 0.01), cirrhosis (P = 0.031), vascular invasion (P = 0.002), or microscopic vascular invasion (P = 0.002), as well as with the tumor grade (P < 0.001). Silencing both ZKSCAN1mRNA and circZKSCAN1 promoted cell proliferation, migration, and invasion. In contrast, overexpression of both forms of RNA repressed HCC progression in vivo and in vitro. Silencing or overexpression of both forms of RNA did not interfere with each other. RNA‐seq revealed a very different molecular basis for the observed effects; ZKSCAN1mRNA mainly regulated cellular metabolism, while circZKSCAN1 mediated several cancer‐related signaling pathways, suggesting a nonredundant role for ZKSCAN1mRNA and circRNA. In conclusion, our results revealed two post‐translational products (ZKSCAN1mRNA and circZKSCAN1) that cooperated closely with one another to inhibit growth, migration, and invasion of HCC. cirZKSCAN1 might be a useful marker for the diagnosis of HCC.
Olivine fabrics and tectonic evolution of fore‐arc mantles: A natural perspective from the Songshugou dunite and harzburgite in the Qinling orogenic belt, central China

Published: February 2017

AbstractTo advance our understanding of the deformation characteristics, rheological behaviors, and tectonic evolution of the fore‐arc lithospheric mantle, we analyzed mineral fabrics for a large spinel‐bearing ultramafic massif in the Songshugou area in the Qinling orogenic belt, central China. In the spinel‐poor coarse‐grained dunite, stronger A/D‐type and weaker C‐type‐like fabrics were found, whereas the spinel‐rich coarse‐grained dunite displayed a comparatively stronger B‐type‐like fabric. These olivine fabrics are high‐T fabrics influenced by the presence of melt, in which B and C‐type‐like fabrics are inferred to be produced by melt‐assisted grain boundary sliding during synkinematic high‐T melt‐rock reactions. In contrast, the spinel‐poor porphyroclastic and fine‐grained dunites present weak AG and B‐type‐like fabrics, respectively. Their olivine fabrics (low‐T fabrics) are inferred to transform from A/D‐type fabric in their coarse‐grained counterparts possibly through mylonitization process assisted by low‐T fluid‐rock reactions, during which strain was accommodated by the fluid‐enhanced dislocation slip and/or fluid‐assisted grain boundary sliding processes. Combined with the tectonic results of our previous work, the high‐T olivine fabrics are probably related to a young and warm fore‐arc mantle where intense partial melting and high‐T boninitic melt‐rock reactions prevalently occurred, whereas the low‐T olivine fabrics likely reflect the evolving tectonic settings through the cooling fore‐arc mantle to a continental lower crust in a collisional orogeny where low‐T fluid‐rock reactions were pervasively activated. These low‐T olivine fabrics imply that though cold, the fore‐arc lithospheric mantle may be locally weak (∼20–30 MPa), allowing ductile deformation to occur at a geologically significant strain rate.

AbstractObjectivesA women's breast is a sex‐specific and aesthetic bodily attribute. It is suggested that breast morphology signals maturity, health, and fecundity. The perception of a woman's attractiveness and age depends on various cues, such as breast size or areola pigmentation. Conducted in Poland and Papua, the current study investigated how breast attractiveness, and the further estimate of a woman's age based on her breast's appearance, is affected by the occurrence of breast ptosis (ie, sagginess, droopiness).MethodsIn the Polish sample, 57 women and 50 men (N = 107) were presented with sketches of breasts manipulated to represent different stages of ptosis based on two different breast ptosis classifications. The participants were asked to rate the breast attractiveness and age of the woman whose breasts were depicted in each sketch. In Papua, 45 men aged 20 to 75 years took part in the study, which was conducted using only one of the classifications of breast ptosis.ResultsRegardless of the classification used, the results showed that the assessed attractiveness of the breasts decreased as the estimated age increased with respect to the more ptotic breasts depicted in the sketches. The results for Papuan raters were the same as for the Polish sample.ConclusionsBreast ptosis may be yet another physical trait that affects the perception and preferences of a potential sexual partner. The consistency in ratings between Polish and Papuan raters suggests that the tendency to assess ptotic breasts with aging and a loss of attractiveness is cross‐culturally universal.

Published: February 2017

AbstractEnergy transfer dynamics of formate (HCOOa) decomposition on a Cu(110) surface has been studied by measuring the angle‐resolved intensity and translational energy distributions of CO2 emitted from the surface in a steady‐state reaction of HCOOH and O2. The angular distribution of CO2 shows a sharp collimation with the direction perpendicular to the surface, as represented by cosnθ (n=6). The mean translational energy of CO2 is measured to be as low as 100 meV and is independent of the surface temperature (Ts). These results clearly indicate that the decomposition of formate is a thermal non‐equilibrium process in which a large amount of energy released by the decomposition reaction of formate is transformed into the internal energies of CO2 molecules. The thermal non‐equilibrium features observed in the dynamics of formate decomposition support the proposed Eley–Rideal (ER)‐type mechanism for formate synthesis on copper catalysts.

AbstractSilicon carbide materials, as leading wide band gap semiconductors, hold significant importance in semiconductor technologies. Herein, diamond‐like 3D materials with low density, but high elasticity properties, have been designed from first‐principles calculations. They are porous single‐crystalline materials composed of sp3‐hybridized silicon (or germanium) and sp‐type C≡C (or B≡N) linear moieties; their stabilities are comparable to those of recently prepared SiC4 materials. Moreover, such wide band gap semiconductors have strong absorption over a wide UV range and exhibit superlight, superflexible, and incompressible mechanical properties, and their optoelectronic and mechanical properties can be well tuned through structural modifications. Such features provide high potential for practicable application under extreme conditions, and suggest promising applications for the design of UV optoelectronic devices.

To date, many studies have been conducted to find out the underlying mechanisms of hyperglycemia‐induced complications in diabetes mellitus, attributed to the cellular pathologies of different cells—especially endothelial cells. However, there are still many ambiguities and unresolved issues to be clarified. Here, we investigated the alteration in biophysical and biochemical properties in human umbilical vein endothelial cells exposed to a high‐glucose concentration (30mM), comparable to glucose content in type 2 diabetes mellitus, over a course of 120 hours. In addition to a reduction in the rate of cell viability and induction of oxidative stress orchestrated by the high‐glucose condition, the dynamic of the fatty acid profile—including polyunsaturated, monounsaturated, and saturated fatty acids—was also altered in favor of saturated fatty acids. Genetic imbalances were also detected at chromosomal level in the cells exposed to the abnormal concentration of glucose after 120 hours. Moreover, the number of tip cells (CD31+/CD34+) and in vitro tubulogenesis capability negatively diminished in comparison to parallel control groups. We found that diabetic hyperglycemia was associated with a decrease in the cell‐cell tight junction and upregulation in vascular endothelial cadherin and zonula occludens (ZO)‐1 molecules after 72 and 120 hours of exposure to the abnormal glucose concentration, which resulted in a profound reduction in transendothelial electrical resistance. The surface plasmon resonance analysis of the human umbilical vein endothelial cells immobilized on gold‐coated sensor chips confirmed the loosening of the cell to cell intercellular junction as well as stable attachment of each cell to the basal surface. Our findings highlighted the disturbing effects of a diabetic hyperglycemia on either biochemical or biophysical properties of endothelial cells.
