Published: November 2019

Background: The global prevalence of diabetes is increasing worldwide. In Morocco, diabetes and depression are major public health problems, requiring improvement in their care. Diabetes and depression are associated with morbidity and early mortality. This association contributes to raising the risk of the complications that occur, while causing higher suffering to patients, as also an increased cost toward healthcare. Aim: This study aims to assess the prevalence of depression in patients with type 2 diabetes (T2D), and identify the main risk factors for depression in this category of diabetic patients. Patients and Methods: Type 2 diabetic patients and older than 18 years of age were recruited. The exclusion criteria included being type 1 diabetic, pregnant woman, hospitalized patients, a history of neurological disorders, such as, stroke, infectious episidodes, and history of psychiatric disorders. The individual patient data was collected through individual and confidential interviews lasting 30 minutes, at the end of the diabetology consultation, by the same diabetologist, trained to use the psychometric scales that were needed. The Moroccan–Arabic version of the Beck diagnostic scale of depression was used. Patients assessed with depressive disorders were reviewed in a specialized psychiatric consultation. The statistical analysis was achieved by using SPSS package (version 17). We retained a threshold P value of 0.05. Settings and Design: A cross-sectional study was conducted that included adults with type 2 diabetes. The depression diagnosis was performed using the Arabic version of the Beck Depression scale. Statistical Analysis: We included 142 patients with type 2 diabetes, with an average age of 56.26 years. The prevalence of depression was 33.1%. The risk factors recognized for depression were, lack of social security, hypertension, and a history of type 2 diabetes of more than five years. Results and Conclusions: In this study, we have focused on the frequent association of ‘Type 2 diabetes and depression’ and the risk of mutual aggravation of both pathologies that might require multidisciplinary healthcare, as well as, improvement in the risk factors of depression through improved access to healthcare, with the extension of social security. The stability of the healthcare personnel involved in the treatment of both chronic diseases, including diabetes and hypertension screening, should also be considered for better management of psychiatric complications.

Published: November 2019

Medulloepithelioma is an extremely rare PNET in late adolescence and adults with only two cases noted in literature. These are WHO grade IV tumors with dismal prognosis. Only few cases survived beyond 5 months. We report a rare case of supratentorial medulloepithelioma in a 17 year old girl. She had presented with right sided weakness, headache and vomiting. Imaging showed an enhancing mass lesion in left parietal region which undergone gross total resection. After surgery, her headache, vomiting and right sided weakness improved. On histopathology, the tumor had characteristic trabecular, ribbon and palisaded arrangement with brisk mitotic activity, necrosis and calcification. Immuno-histochemistry revealed positivity for Synaptophysin, Vimentin and EMA while GFAP was negative. MIB-1 labeling was very high. Patient received postoperative radiotherapy. On follow up after 14 months, she was clinically asymptomatic with no recurrence on imaging.
Spontaneous hemothorax associated with neurofibromatosis type I: A review of the literature
Authors: Pulivarthi Swaroopa , Simmons Byron , Shearen John , Gurram Murali Krishna
Published: November 2019

Neurofibromatosis is generally a benign disease, but has the potential for rare and fatal complications, such as spontaneous hemothorax. We report a case of massive hemothorax due to neurofibroma in a 49-year-old woman with neurofibromatosis type 1. The configuration of the radiological opacity and frank blood withdrawn on thoracentesis should suggest the diagnosis of hemothorax in a patient with neurofibromatosis. Surgical treatment for hemothorax is limited by arterial fragility and the prognosis is relatively poor. Any evidence of aneurysmal disease in the thoracic vessels should be aggressively managed percutaneously by coil embolization to prevent future rupture.

Published: November 2019

Olfactory region schwannomas are rare, but when they occur, they commonly arise from the meningeal branches of the trigeminal nerve and may present without involvement of the olfaction. A 24 year old lady presented with hemifacial paraesthesias. Radiology revealed a large olfactory region enhancing lesion. She was operated through a transbasal with olfactory preserving approach. This manuscript highlights the importance of olfactory preservation in such lesions.
A Case Report Describing Three Cases of Challenging or Failed Intubation after Cervical Spine Surgery: A Peril of Early Extubation
Authors: Mishra Puneet , Mishra Kelly Louise , Palmer Cassandra , Robertson Amy
Published: November 2019

Postoperative airway complications can be a common, yet perhaps underappreciated, complication in patients undergoing cervical spine surgery. Presented here are three cases in which patients experienced postoperative airway compromise, resulting in difficulty establishing a secure airway following cervical spine operations. Establishing factors that contribute to airway complications after cervical spine surgery can aid in early identification of high-risk patients to create an appropriate airway management strategy. Ultimately, the frequency of airway difficulty after removal of the endotracheal tube in patients undergoing cervical spine surgery should not be taken lightly.

Published: November 2019

The surface band bending in Ga-polar n-type GaN surfaces, as well as the effect of Si doping levels and in situ Ar+ ion processing on band bending, was systematically investigated. To precisely determine the valence band maximum (VBM) of GaN beyond instrumental and material surface environments by XPS, a valence band feature fitting procedure based on photoemission spectra and theoretical densities of states has been developed. Poisson calculation with quadratic depletion approximation on surface potential has been used to model the band bending and further correct the VBM energy. Then, the actual surface band bending was correctly evaluated. Upward band bending of 1.55 ± 0.03 eV with highly Si doped n-GaN, which is about 0.88 eV higher than that of the moderately doped sample, was found. After in situ Ar+ plasma treatment, the varying degree of band bending was observed distinctly depending on the Si doping density. The surface components associated with the Ga/N ratio and Ga–O bonding concentration on the n-GaN surface have been used to evaluate the contribution to surface band bending.
Four-component relativistic time-dependent density-functional theory using a stable noncollinear DFT ansatz applicable to both closed- and open-shell systems
Authors: Komorovsky Stanislav , Cherry Peter J. , Repisky Michal
Published: November 2019

We present a formulation of relativistic linear response time-dependent density functional theory for the calculation of electronic excitation energies in the framework of the four-component Dirac-Coulomb Hamiltonian. This approach is based on the noncollinear ansatz originally developed by Scalmani and Frisch [J. Chem. Theory Comput. 8, 2193 (2012)] and improves upon the past treatment of the limit cases in which the spin density approaches zero. As a result of these improvements, the presented approach is capable of treating both closed- and open-shell reference states. Robust convergence of the Davidson-Olsen eigenproblem algorithm for open-shell reference states was achieved through the use of a solver which considers both left and right eigenvectors. The applicability of the present methodology on both closed- and open-shell reference states is demonstrated on calculations of low-lying excitation energies for Group 3 atomic systems (Sc3+–Ac3+) with nondegenerate ground states, as well as for Group 11 atomic systems (Cu–Rg) and octahedral actinide complexes (PaCl62−, UCl6−, and NpF6) with effective doublet ground states.
Novel polarity effect on intermetallic compound thickness changes during electromigration in Cu/Sn-3.0Ag-0.5Cu/Cu solder joints
Authors: Jin Zhi , Shen Yu-An , He Siliang , Zhou Shiqi , Chan Y. C. , Nishikawa Hiroshi
Published: November 2019

Growth of an intermetallic compound (IMC) plays a critical role in the reliability of flip-chip solder joints. It has been found that IMC growth is accelerated on the anode and inhibited on the cathode during electromigration (EM), although there are discrepancies in the relevant literature. In this study, Cu/Sn3.0Ag0.5Cu/Cu solder joints were examined by EM under a current density of 1×104A/cm2 at 150 °C; an aging test was conducted at 150 °C to compare the EM results. Cu atoms are the dominant diffusion species that migrate from the cathode to the anode during EM. The increase in IMC thickness at the anode is divided into two stages: during stage 1, the IMC thickness first grows with a gradual linear tendency, followed by retarded IMC growth. During stage 2, the EM driving force dominates IMC growth because of the high IMC thickness after stage 1, inducing a lower Cu concentration gradient and decreasing the driving force of the chemical potential. At the cathode, the IMC thickness fluctuates between two threshold values. This phenomenon is attributed to the competition between the effects of chemical potential and EM on IMC growth. In the initial stage, the chemical potential is sufficiently large to induce considerable Cu flux from the Cu underbump metallization into the Sn solder, inducing IMC growth. When the IMC becomes too thick to significantly reduce the chemical potential, a substantial number of Cu atoms migrate via EM, reducing the IMC thickness at the cathode. However, when IMC thickness decreases, the chemical potential again increases and enhances IMC growth. Therefore, thresholds 1 and 2 may be set based on changes observed in the IMC thickness at the cathode during EM. These findings elucidate the polarity effect in intermetallic compounds, and its effect on the stability of solder joints.
On algebraic properties of the sub-block of zero field hyperfine Hamiltonian with penultimate total spin projection for arbitrary hyperfine structure, and field dependence of radical pair recombination probability in the vicinity of zero field
Authors: Stass Dmitri V.
Published: November 2019

Basic algebraic arguments demonstrate that the probability of radical pair recombination in low field for an arbitrary pair with Hamiltonian confined to Zeeman and isotropic hyperfine interactions contains two additive contributions linear with applied field with equal, but opposite in sign, proportionality factors. Their weights are determined by the probability of having all nuclear spins along the field in the initial electron-singlet state of the pair, and in the case of equilibrium with respect to nuclear spins, the two contributions completely compensate the field dependences of each other, producing an additive term in the singlet yield with zero derivative. However, if the nuclear set is polarized, a linear skew proportional to polarization appears, introducing anisotropy in the intrinsically spherically symmetric system. The key element in this derivation is guaranteed nondegeneracy of the eigenvalues of the “penultimate” (Mmax − 1) block of the Hamiltonian for a radical with any number of distinct spin-1/2 nuclei in zero field, which leads to guaranteed applicability of the first-order nondegenerate perturbation theory with nonvanishing linear in field admixture of states, persisting all the way into the final expression for singlet yield for a pair with an arbitrary isotropic hyperfine structure. We argue that this behavior of the field dependence of recombination yield is representative of a radical pair of an arbitrarily complex hyperfine structure; this may be a possible mechanism for anisotropic response (“chemical compass”) for an isotropic radical pair based system with isotropic-only internal interactions and anisotropy introduced via the initial state of nuclei, while such an approach may complement the usually needed numerical simulations.
What does the instantaneous normal mode spectrum tell us about dynamical heterogeneity in glass-forming fluids?
Authors: Zhang Wengang , Douglas Jack F. , Starr Francis W.
Published: November 2019

We examine the instantaneous normal mode spectrum of model metallic and polymeric glass-forming liquids. We focus on the localized modes in the unstable part of the spectrum [unstable localized (UL) modes] and find that the particles making the dominant contribution to the participation ratio form clusters that grow upon cooling in a fashion similar to the dynamical heterogeneity in glass-forming fluids, i.e., highly mobile (or immobile) particles form clusters that grow upon cooling; however, a comparison of the UL mode clusters to the mobile and immobile particle clusters indicates that they are distinct entities. We also show that the cluster size provides an alternate method to distinguish localized and delocalized modes, offering a significant practical advantage over the finite-size scaling approach. We examine the trajectories of particles contributing most to the UL modes and find that they have a slightly enhanced mobility compared to the average, and we determine a characteristic time quantifying the persistence time of this excess mobility. This time scale is proportional to the structural relaxation time τα of the fluid, consistent with a prediction by Zwanzig [Phys. Rev. 156, 190 (1967)] for the lifetime of collective excitations in cooled liquids. Evidently, these collective excitations serve to facilitate relaxation but do not actually participate in the motion associated with barrier crossing events governing activated transport. They also serve as a possible concrete realization of the “facilitation” clusters postulated in previous modeling of glass-forming liquids.
Creating and controlling complex light
Authors: Bender Nicholas , Yılmaz Hasan , Bromberg Yaron , Cao Hui
Published: November 2019

Random light fields—commonly known as speckles—demonstrate Rayleigh intensity statistics and only possess local correlations which occur within the individual speckle grains. In this work, we develop an experimental method for customizing the intensity probability density function (PDF) of speckle patterns while simultaneously introducing nonlocal spatial correlations among the speckle grains. The various families of tailored speckle patterns—created by our method—can exhibit radically different topologies, statistics, and variable degrees of spatial order. Irrespective of their distinct statistical properties, however, all of these speckles are created by appropriately encoding high-order correlations into the phase front of a monochromatic laser beam with a spatial light modulator. In addition to our experimental demonstration, we explore both the theoretical and practical limitations on the extent to which the intensity PDF and the spatial intensity correlations can be manipulated concurrently in a speckle pattern. This work provides a versatile methodology for creating complex light fields and controlling their statistical properties with varied applications in microscopy, imaging, and optical manipulation.

The Single Disulfide-Directed β-Hairpin Fold: Role of Disulfide Bond in Folding and Effect of an Additional Disulfide Bond on Stability
Authors: Chittoor Balasubramanyam , Krishnarjuna Bankala , Morales Rodrigo A. V. , Norton Raymond S.
Published: November 2019

Disulfide bonds play a key role in the oxidative folding, conformational stability, and functional activity of many peptides. A few disulfide-rich peptides with privileged architecture such as the inhibitor cystine knot motif have garnered attention as templates in drug design. The single disulfide-directed β-hairpin (SDH), a novel fold identified more recently in contryphan-Vc1, has been shown to possess remarkable thermal, conformational, and chemical stability and can accept a short bioactive epitope without compromising the core structure of the peptide. In this study, we demonstrated that the single disulfide bond is critical in maintaining the native fold by replacing both cysteine residues with serine. We also designed an analogue with an additional, non-native disulfide bridge by replacing Gln1 and Tyr9 with Cys. Contryphan-Vc11–22[Q1C, Y9C] was synthesised utilising orthogonal cysteine protection and its solution structure determined using solution NMR spectroscopy. This analogue maintained the overall fold of native contryphan-Vc1. Previous studies had shown that the β-hairpin core of contryphan-Vc1 was resistant to proteolysis by trypsin and α-chymotrypsin but susceptible to cleavage by pepsin. Contryphan-Vc11–22[Q1C, Y9C] proved to be completely resistant to pepsin, thus confirming our design strategy. These results highlight the role of the disulfide bond in maintaining the SDH fold and provide a basis for the design of more stable analogues for peptide epitope grafting.

Published: November 2019

From January 2008 to December 2009, 451 specimens of witch guitarfish Zapteryx xyster were caught in the Gulf of Tehuantepec. Total weight, total length (TL), sex, maturity stage and catch depth were recorded for each specimen. Maturity stage distribution exhibited significant differences with respect to depth. The data indicated that adults migrated towards shallow waters (25–37m) to reproduce, starting in February. Males reached maturity at 44cmTL, whereas females reached maturity at 48cmTL. Witch guitarfish females are synchronous; therefore, ovulation and mating begin in March and parturition begins in April. Females showed a 2-year cycle with consecutive vitellogenesis and gestation. Fecundity was five to eight embryos (mean six embryos) and the sex ratio of embryos was 1:1. Birth occurred in April and May, with an average size at parturition of 17.3cmTL. There was sexual dichromatism between males and females during the breeding period, and sexual polymorphism in adult females. The incidental catch of the witch guitarfish during courtship and mating threatens the survival of this species.

Published: November 2019

Significance

Chiral molecules interact and react differently, depending on their handedness (left vs. right). This chiral recognition is the principle governing most biomolecular interactions, such as the activity of drugs or our perception of scents. In spite of this fundamental importance, a real-time (femtosecond) observation of chirality during a chemical reaction has remained out of reach in the gas phase. In the present work, we report this breakthrough with a seemingly unlikely technique: high-harmonic generation (HHG) in tailored intense near-infrared laser fields. Combining the transient-grating technique with HHG in counterrotating circularly polarized laser fields, we follow the temporal evolution of molecular chirality during a chemical reaction from the unexcited electronic ground state through the transition-state region to the final achiral products.
Relationships between perceived coach leadership, athletes’ use of coping and emotions among competitive table tennis players
Authors: González‐García Higinio , Martinent Guillaume
Published: November 2019

The aims of this study were to examine: (a) whether coach leadership behaviours predict athletes’ use of coping and (b) whether coping predicts athletes’ emotional outcomes in competition. A sample of 180 table tennis players (M age = 33.87; SD = 16.64; 149 men and 31 women) voluntarily participated in the study. A partial least square path modelling (PLS‐PM) approach was used to examine the relationships between the study variable. The results showed that: (a) coach democratic behaviour was significantly related to task‐oriented coping; (b) task‐oriented coping was significantly related to excitement and happiness; (c) distraction‐oriented coping was significantly related to anxiety, dejection and anger. As a whole, PLS‐PM results suggested that coach democratic behaviour could be the better style in relationship with positive coping and emotion outcomes in table tennis players.
Targeting interleukin-17 in chronic inflammatory disease: A clinical perspective
Authors: Zwicky Pascale , Unger Susanne , Becher Burkhard
Published: November 2019

Chronic inflammatory diseases like psoriasis, Crohn’s disease (CD), multiple sclerosis (MS), rheumatoid arthritis (RA), and others are increasingly recognized as disease entities, where dysregulated cytokines contribute substantially to tissue-specific inflammation. A dysregulation in the IL-23/IL-17 axis can lead to inflammation of barrier tissues, whereas its role in internal organ inflammation remains less clear. Here we discuss the most recent developments in targeting IL-17 for the treatment of chronic inflammation in preclinical models and in patients afflicted with chronic inflammatory diseases.

Published: November 2019

The EMI-compatibility of the LabPET II detection module (DM) to develop a high-resolution simultaneous PET/MRI system is investigated. The experimental set-up evaluates the performance of two LabPET II DMs in close proximity to RF coils excited at three different frequencies mimicking the electromagnetic environments of 3 T, 7 T, and 9.4 T MRI scanners. A gradient coil, with switching frequency from 10 kHz to 100 kHz, also surrounds one of the DMs to investigate the effects of the gradient field on the individual detector performance, such as the baseline of the DC-voltage and noise level along with both the energy and coincidence time resolutions. Measurements demonstrate a position shift of the energy photopeaks (⩽9%) and a slight deterioration of the energy and coincidence time resolutions in the presence of electromagnetic interferences from the gradient and RF coils. The electromagnetic interferences cause an average degradation of up to ~50% of the energy resolution (in time-over-threshold spectra) and up to 18% of the timing resolution. Based on these results, a modified version of the DM, including a composite shielding as well as an improved heat pipe-based cooling mechanism, capable of stabilizing the temperature of the DM at ~40 °C, is proposed and investigated. This shielded version shows no evidence of performance degradation inside an MRI-like environment. The experimental results demonstrate that a properly shielded version of the LabPET II DM is a viable candidate for an MR-compatible PET scanner.

Published: November 2019

An explanation of optical unitary transformation is presented for general nonoverlapping-image multimode interference (MMI) couplers with any number of input and output ports. The light transformation in the MMI coupler can be considered as an optical field matrix acting on an input light column vector. We investigate the general phase principle of output light image. The complete proof of nonoverlapping-image MMI coupler’s optical unitarity along with the phase analysis of matrix element is provided. Based on a two-dimensional finite-difference time-domain (2D-FDTD) simulation, the unitary transformation is obtained for a 4 × 4 nonoverlapping-image MMI coupler within a deviation of 4 × 10−2 for orthogonal invariance and 8 × 10−2 for transvection invariance in the C-band spectral range. A compact 1 × 4 splitter based on cascaded MMI coupler is proposed, showing a phase deviation less than 5.4° while maintaining a low-loss performance in C-band spectra.

Published: November 2019

It is desirable to have electromagnetic wave absorbers with ultrathin structural thickness and broader spectral absorption bandwidth with numerous applications in optoelectronics. In this paper, we theoretically propose and numerically demonstrate a novel ultrathin nanostructure absorber composed of semiconductor nanoring array and a uniform gold substrate. The results show that the absorption covers the entire visible light region, achieving an average absorption rate more than 90% in a wavelength range from 300 nm to 740 nm and a nearly perfect absorption from 450 nm to 500 nm, and the polarization insensitivity performance is particularly great. The absorption performance is mainly caused by the electrical resonance and magnetic resonance of semiconductor nanoring array as well as the field coupling effects. Our designed broadband visible light absorber has wide application prospects in the fields of thermal photovoltaics and photodetectors.

The present article aims to study the level of students satisfaction of PGRI Yogyakarta University towards service and facilities quality. To try and understand the factors which influence student satisfaction as well as consequences of it, this study test a weighted least squares model. This study investigate determinant and dominant factors of the students satisfaction and its characteristics. The data were collected through a questionnaire administered to 644 students of PGRI Yogyakarta University to investigate their perceptions of the universities services. A questionnaire containing 30 questions has been used for data collection. The data were analyzed using the descriptive technique and the weighted least sqares analysis. The measurement of the service quality is an important element to provide better, more efficient and more effective services. Spss Software and cronbach alpha index have been used for data analysis and reliability. The reliability factor should be improved first because it is dominant in determining the students’ satisfaction. Quality indicators constituting the reliability factor include classroom, library, laboratory, public area, and information system.

The results show that, by percentage, 2 indicator is in the very good category, only 5 indicators are in the good category, 9 indicators are in the fairly good category, and 14 indicators are in the poor category. The results indicate that the universities service quality needs to be improving. The results of the analysis show that five determinant factors of the students’ satisfaction include tangibles, reliability, responsiveness, assurance, and empathy. By the priority scale, the reliability factor should be improved first because it is dominant in determining the students’ satisfaction.
Nutritional Status and Its Impact on Academic Performance of Selected Grade 8 Students
Authors: Beredo  , Aceron Aubrey
Published: November 2019

This study aimed to determine the nutritional status, causes of malnutrition and its impact on the academic performance of Grade 8 Students with wasted and severely wasted BMI. The researcher used the descriptive – correlational research method which described the relationship between variables. Four (4) variables were used in this study such as poverty, health condition, eating habits, and illiteracy. The results showed that sometimes health condition and illiteracy are the contributing factors for malnutrition as evidenced by the average mean of 3.06 and 3.58 respectively. While most often, poverty and eating habits contributed to the causes of malnutrition. A negligible negative correlation existed between weight and academic performance based on the computed r value which was less than the tabular value of 0.349 at 5% level of significance. The obtained chi-square value between nutritional status and academic performance was found to be insignificant since the obtained chi-square value was less than the tabular value of 9.488 at 5% level of significance. Thus, the researcher recommends that continuing School-Based feeding program be strengthened. Further, it is also recommended to encourage the active involvement of parents, communities and local government in the implementation of intensified school nutrition program.

Published: November 2019

This study was conducted to measure how useful intensified workshop to assist DepED teachers in Science and Mathematics in doing action research. The researchers joined in the In-Service Training for Teachers in the 5th District of Iloilo. They discussed concept and procedures on how to formulate action researches. The results showed that several of these science and mathematics teachers had produced title coming from their innovations but very few were successful. This is due to lack of interest and unambiguous understanding of action research.

Furthermore, with highly committed mentors; one elementary science teachers were able to complete the action research and presented in a local science organization. However, none of the mathematics teachers were able to make any proposal due to co-curricular activities like coaches for sports and literary events or advisers for clubs and organization given by their supervisors and principals. Thus, the findings of the study recommended that teachers with high potentials in conducting action research must be recognized, and also promote collaborative efforts among colleagues to help one another to make innovative outputs into functional products to enhance the learning of below average learners.
