Health Locus of Control and Health Promoting Behaviors among Nursing and Non-Nursing Students in Zagazig University , Egypt

A solid society arises with healthy youth. University students speak to the future of nations. University is a time of expanded responsibility for choices and healthy practices. Such behaviors could continue into middle and old age to perpetrate health hazards later in life. The existing study aimed to investigate the relation between health promoting behaviors and health locus of control among Zagazig University nursing and non-nursing students, hence, a comparative cross sectional study design was used. A selfadministered questionnaire sheet was used to collect data from 1188 undergraduate student. Study results revealed that in terms of health promoting behaviors, nursing students had higher mean score regarding health responsibility, social support and stress management sub items compared to life appreciation, nutrition and exercise among non-nursing. As to health locus of control, internal and powerful others locus was higher among nursing students, while chance sub item mean score was higher among non-nursing students. Conclusion, being nursing or non-nursing student only accounted for a small fraction of variation in health locus of control and health promoting behavior. Taken as whole, believing in health control regardless of its locus is positively correlated with health promoting behaviors among both nursing and non-nursing students. Consequently it is recommended to tailor nursing interventions to encourage healthy behaviors specially nutrition and exercise for nursing students, and health responsibility, and stress management for nonnursing students.
A new medium for remote music tuition

It is common to learn to play an orchestral musical instrument through regular one-to-one lessons with an experienced musician as a tutor. Students may work with the same tutor for many years, meeting regularly to receive real-time, iterative feedback on their performance. However, musicians travel regularly to audition, teach and perform and this can sometimes make it difficult to maintain regular contact. In addition, an experienced tutor for a specific instrument or musical style may not be available locally. General instrumental tuition may not be available at all in geographically distributed communities. One solution is to use technology such as videoconference to facilitate a remote lesson; however, this fundamentally changes the teaching interaction. For example, as a result of the change in communication medium, the availability of non-verbal cues and perception of relative spatiality is reduced. We describe a study using video-ethnography, qualitative video analysis and conversation analysis to make a fine-grained examination of student–tutor interaction during five co-present and one video-mediated woodwind lesson. Our findings are used to propose an alternative technological solution – an interactive digital score. Rather than the face-to-face configuration enforced by videoconference, interacting through a shared digital score, augmented by visual representation of the social cues found to be commonly used in co-present lessons, will better support naturalistic student–tutor interaction during the remote lesson experience. Our findings may also be applicable to other fields where knowledge and practice of a physical skill sometimes need to be taught remotely, such as surgery or dentistry.
Adverse Events During Perampanel Adjunctive Therapy in Intractable Epilepsy

Background and Purpose Perampanel is the first α-amino-3-hydroxy-5-methyl-4-isoxazole-propionic acid (AMPA)-receptor antagonist developed to treat epilepsy. The effects of either rapid or slow dose titration on adverse events remain to be elucidated. Methods Eighty-five patients received perampanel between March 2016 and August 2016. Patients were divided into two groups according to their dosing schedule: rapid dose titration (2-mg increments at intervals of 1 to 2 weeks) and slow dose titration (2-mg increments at intervals of at least 3 weeks). Seizure frequency and adverse events were analyzed over 3 months. Results Adverse events were reported by 47 (58%) of the 81 patients analyzed, with 12 (15%) patients discontinuing perampanel due to adverse events. Common adverse events included dizziness (n=30, 37%), aggressive mood and behavior (n=19, 24%), gait disturbance (n=16, 20%), and sleep problems (n=10, 12.4%). The overall adverse events were similar in the slow-titration group (38 of 61 patients) and the rapid-titration group (8 of 20 patients, p=0.081). However, none of the 20 patients in the slow-titration group experienced gait disturbance, compared with 16 of the 61 patients in the rapid-titration group (p=0.009), while appetite change was experienced by 4 patients in the slow-titration group but only 1 in the rapid-titration group (p=0.003). No relationship was noted between adverse events and the maximum dose of perampanel (p=0.116). Sex differences were observed, with the response to perampanel being better and the rate of adverse events being higher in females (p=0.015 and p=0.046, respectively). Conclusions Slow titration of perampanel may reduce perampanel-related adverse events.
Occurrence of filamentous fungi in maize destined for human consumption in South Africa

Abstract One‐hundred maize samples were analyzed for fungal contamination using conventional and molecular methods. The percentage incidence of different genera isolated revealed the predominance of Fusarium (82%), Penicillium (63%), and Aspergillus species (33%) compared to other genera. Fusarium occurred in 90% and 74% of small scale and commercial samples, respectively, while Penicillium occurred in small scale and commercial samples at an incidence rate of 64% and 62%, respectively. However, among the species, Fusarium verticilloides have the highest incidence of 70% and 76% in commercial and small‐scale maize, respectively, while Penicillium digitatum has 56% total incidence. Aspergillus fumigatus (27%) were also the most dominant of these genera. Fungal genera isolated included Alternaria and Cladosporium although occurring at a lower incidence level of 30%, 32% and 16%, 20%, respectively, in small‐scale and commercial samples. The results emphasize that farmers and consumers should be alerted to the danger of fungal contamination in maize.
Microbiological quality control of some non-sterile preparations commonly used in Pakistan.

The quality of medicines in some developing countries including Pakistan is not very satisfactory regarding safety and efficacy. In addition to sterile preparations, the microbial contamination of non sterile preparations should also be monitored according to USP microbial limits for these preparations. This study was designed to check the microbial quality of some commonly used non-sterile preparations available in Pakistan. Total 133 samples containing national and multinational brands of different dosage forms were collected from retail setups of Sargodha, Khushab and Chakwal cities. The total aerobic bacterial count and fungal contamination was tested by pour plate method. The absence of objectionable microorganisms was confirmed by using selective media, biochemical testing and microscopy. Bioburden of these preparations was also tested after a storage period of six months. The bio burden varied among all the selected non-sterile preparations whether of local or multinational brands. The highest load was observed in syrups, among which syrup number 1 showed maximum aerobic count (8.4×106). Lowest count was observed in tablets, among which tablet preparation number 1 contained 1.5×103aerobic bacteria. Creams and capsules produced no recovered bacteria. The fungal contaminants were also observed in all dosage forms except tablets. The isolated organisms included Gramnegative bacteria which contained objectionable ones such as Salmonella, Shigella, Pseudomonas and E.coli and some airborne moulds including Aspergillus spp. , Penicillium spp. , Fusarium spp. and Acremonium spp. Several measures such as GMPs, monitoring programs and SOPs should be followed by the pharmaceutical companies to reduce the microbial contamination level in the non sterile preparations. The regulatory agencies have to implement strict analysis strategy to check the microbial quality of the medicines before their release for sale in the market.
Wheat straw mulching with fertilizer nitrogen: An approach for improving soil water storage and maize crop productivity

Field studies using wheat straw mulching effects on soil water storage and maize development were conducted in China. The studies contained four treatments during three years (2014–2016): CK (no straw and no nitrogen); N (no straw mulching with 172 kg N/ha); HS + N (half straw mulching at the rate of 2500 kg/ha with 172 kg N/ha), and FS + N (full straw mulching at the rate of 5000 kg/ha with 172 kg N/ha). The FS + N treatment significantly increased soil water storage in a drought period during crop growth stages and promoted plant growth along with increased evapotranspiration. The FS + N treatment increased the soil water storage (26.5, 19.9 and 11.1 mm), grain yield (28.7, 6.93 and 2.4%), and water use efficiency (26.6, 6.64 and 2.40%) compared to CK, N and HS + N, respectively. In conclusion, compared to N, HS + N or FS + N increased the biomass (11 and 19%) and water use efficiency (4 and 5%), respectively, and are considered beneficial in Guanzhong, China. Mulching levels were superior to N and compensated the wheat nitrogen requirements. Thus, further studies with minimum fertilizer nitrogen for an environmentally friendly and effective approach are recommended in semiarid regions of China.

Aging of imaging properties of a CMOS flat-panel detector for dental cone-beam computed tomography

We have experimentally investigated the long-term stability of imaging properties of a flat-panel detector in conditions used for dental x-ray imaging. The detector consists of a CsI:Tl layer and CMOS photodiode pixel arrays. Aging simulations were carried out using an 80-kVp x-ray beam at an air-kerma rate of approximately 5 mGy s−1 at the entrance surface of the detector with a total air kerma of up to 0.6 kGy. Dark and flood-field images were periodically obtained during irradiation, and the mean signal and noise levels were evaluated for each image. We also evaluated the modulation-transfer function (MTF), noise-power spectrum (NPS), and detective quantum efficiency (DQE). The aging simulation showed a decrease in both the signal and noise of the gain-offset-corrected images, but there was negligible change in the signal-to-noise performance as a function of the accumulated dose. The gain-offset correction for analyzing images resulted in negligible changes in MTF, NPS, and DQE results over the total dose. Continuous x-ray exposure to a detector can cause degradation in the physical performance factors such the detector sensitivity, but linear analysis of the gain-offset-corrected images can assure integrity of the imaging properties of a detector during its lifetime.
Mechanism of Yanghe Pingchuan granules treatment for airway remodeling in asthma

Purpose Yanghe Pingchuan granules (YPG), a hospital preparation developed by The First Affiliated Hospital, Anhui University of Chinese Medicine, has been used for the clinical treatment of bronchial asthma (BA) for several decades. This study aimed to explore the mechanism of action of YPG in the treatment of BA. Materials and methods Male Sprague Dawley rats (n=60) were randomly divided into six groups (n=10 per group): control, a BA model, positive drug control (Guilong Kechuanning capsules; a proven effective treatment for BA), and model rats treated with a high, medium, or low dose of YPG. H&E staining was used to detect pathological changes in the bronchial tubes. The mRNA expression levels of PI3K, PKB, PCNA, and AR were determined by real-time PCR, and the protein levels of phospho- (p-)PI3K, p-PKB, p-PCNA, and p-AR were detected by Western blotting. ELISAs were used to detect the expression of PIP2, PIP3 IL-6, IL-8, IL-1β, and epinephrine (EPI). Results H&E staining demonstrated that BA can be ameliorated using YPG. Real-time PCR, Western blotting, and ELISA indicated that use of YPG decreased expression of the phosphoinositide 3-kinase (PI3K) signaling pathway and PCNA, and can also ameliorate the condition kidney Yang deficiency, which is associated with BA in Chinese traditional medicine. Conclusion YPG can attenuate BA therapeutically in a dose-dependent manner. The mechanism underlying its therapeutic effect comprises influences on three features that contribute to BA: the PI3K signaling pathway, cell proliferation, and “kidney-Yang deficiency”.
WORKING PAPER 1401 Testing the Expectations Hypothesis with Survey Forecasts : The Impacts of Consumer Sentiment and the Zero Lower Bound in an I ( 2 )

Monthly interest rate forecasts from nearly 50 major financial institutions are used to examine the expectations hypothesis at the short end of the term structure for the Canadian T-bill market and Libor markets in the US, UK, and Switzerland. Using CVARs, the term premium is found to move inversely with consumer sentiment in all four samples at the 1% level. Extension to the polynomial CVAR also suggests that a fall in the interest rate raises the premium, at least temporarily. This is interpreted as arising from the decreasing upside potential for bond price movements related to the zero lower
Experiences of the Marital Relationship among Orthodox Jewish Gay Men in Mixed-Orientation Marriages

This qualitative study describes the marital relationship experiences of Orthodox Jewish gay men in mixed-orientation marriages. In-depth interviews were conducted with 21 men from the northeastern part of North America about their experiences of being gay in their Orthodox religious communities. Spontaneous accounts of their experiences within the marital relationship were reported by all participants. A content analysis revealed four primary themes: reasons for getting married, the role of the Orthodox community in sustaining the marriage, quality of the marital relationship, and the impact of homosexuality on the marital relationship. Findings suggest that religion and the Orthodox community play a major role in gay Orthodox Jewish men's decision to marry and in sustaining the marriage. In addition, findings suggest that the marital relationship is experienced as a task-centered teamwork and not as a source of support and intimacy. Finally, although rarely discussed in the relationship, their sexual orientation greatly influences these men's attitudes, behaviors, and feelings toward their wives.
Oral tissue response to soft tissue expanders prior to bone augmentation: in vitro analysis and histological study in dogs

Purpose To determine whether the swelling and mechanical properties of osmotic self-inflating expanders allow or not the induction of intraoral soft tissue expansion in dogs. Methods Three different volumes (0.15, 0.25, and 0.42 mL; referred to respectively as the S, M, and L groups) of soft tissue expanders (STEs) consisting of a hydrogel core coated with a silicone-perforated membrane were investigated in vitro to assess their swelling behavior (volume swelling ratio) and mechanical properties (tensile strength, tensile strain). For in vivo investigations, the STEs were subperiosteally inserted for 4 weeks in dogs (n=5). Soft tissue expansion was clinically monitored. Histological analyses included the examination of alveolar bone underneath the expanders and thickness measurements of the surrounding fibrous capsule. Results The volume swelling ratio of all STEs did not exceed 5.2. In tensile mode, the highest mean strain was registered for the L group (98.03±0.3 g/cm), whereas the lowest mean value was obtained in the S group (81.3±0.1 g/cm), which was a statistically significant difference (P<0.05). In addition, the S and L groups were significantly different in terms of tensile strength (1.5±0.1 g/cm for the S group and 2.2±0.1 g/cm for the L group, P<0.05). Clinical monitoring showed successful dilatation of the soft tissues without signs of inflammation up to 28 days. The STEs remained volumetrically stable, with a mean diameter in vivo of 6.98 mm, close to the in vitro post-expansion findings (6.69 mm). Significant histological effects included highly vascularized collagen-rich fibrous encapsulation of the STEs, with a mean thickness of 0.67±0.12 mm. The bone reaction consisted of resorption underneath the STEs, while apposition was observed at their edges. Conclusions The swelling and mechanical properties of the STEs enabled clinically successful soft tissue expansion. A tissue reaction consisting of fibrous capsule formation and bone loss were the main histological events.
Export production fluctuations in the eastern equatorial Pacific during the Pliocene‐Pleistocene: Reconstruction using barite accumulation rates

Export production is an important component of the carbon cycle, modulating the climate system by transferring CO2 from the atmosphere to the deep ocean via the biological pump. Here we use barite accumulation rates to reconstruct export production in the eastern equatorial Pacific over the past 4.3 Ma. We find that export production fluctuated considerably on multiple time scales. Export production was on average higher (51 g C m−2 yr−1) during the Pliocene than the Pleistocene (40 g C m−2 yr−1), decreasing between 3 and 1 Ma (from more than 60 to 20 g C m−2 yr−1) followed by an increase over the last million years. These trends likely reflect basin-scale changes in nutrient inventory and ocean circulation. Our record reveals decoupling between export production and temperatures on these long (million years) time scale. On orbital time scales, export production was generally higher during cold periods (glacial maxima) between 4.3 and 1.1 Ma. This could be due to stronger wind stress and higher upwelling rates during glacial periods. A shift in the timing of maximum export production to deglaciations is seen in the last ~1.1 million years. Results from this study suggest that, in the eastern equatorial Pacific, mechanisms that affect nutrient supply and/or ecosystem structure and in turn carbon export on orbital time scales differ from those operating on longer time scales and that processes linking export production and climate-modulated oceanic conditions changed about 1.1 million years ago. These observations should be accounted for in climate models to ensure better predictions of future climate change.
Evaluation of highly carbonated hydroxyapatite bioceramic implant coatings with hierarchical micro-/nanorod topography optimized for osseointegration

Background Optimal osseointegration has been recognized as a pivotal factor in determining the long-term success of biomedical implants. Materials and methods In the current study, highly carbonated hydroxyapatite (CHA) with carbonate contents of 8, 12 and 16 wt% and pure hydroxyapatite (HA) were fabricated via a novel hydrothermal method and deposited on the titanium substrates to generate corresponding CHA bioceramic coatings (designated as C8, C12 and C16, respectively) and HA bioceramic coatings (designated as C0). Results C8, C12 and C16 were endowed with nanoscale, hierarchical hybrid micro-/nanoscale and microscale surface topographies with rod-like superstructures, respectively. Compared with C0, the micro-/nanotextured CHA bioceramic coatings (C8, C12 and C16) possessed excellent surface bioactivity and biocompatibility, as well as better wettability, which mediated improved protein adsorption, giving rise to simultaneous enhancement of a biological cascade of events of rat bone-marrow-derived mesenchymal stem cells including cell adhesion, proliferation, osteogenic differentiation and, notably, the production of the pro-angiogenic growth factor, vascular endothelial growth factor-A. In particular, C12 with biomimetic hierarchical hybrid micro-/nanorod topography exhibited superior fractal property and predominant performance of protein adsorption, cell adhesion, proliferation and osteogenesis concomitant with angiogenesis. Conclusion All these results suggest that the 12 wt% CHA bioceramic coating with synergistic modification of surface chemistry and topography has great prospect for future use as implant coating to achieve optimum osseointegration for orthopedic and dental applications.
Robust mixed finite element simulations of interactions of ultrasonic waves with cracks

We are faced with interactions of ultrasonic waves with cracks in thin plates. These are important means in structural health monitoring of aircrafts. We present a couple of finite element models that are validated by means of Lamb dispersive (frequency-velocity) curves. In 2d it turns out that membranes and Kirchhoff plates imitate well the low frequency case of the lowest-order shear and bending modes, respectively. We switch to 3d displacement finite elements enhanced with higher-order ansatz functions in the thickness direction. These imitate properly the shear-horizontal modes, however, they suffer from the locking effect in case of the Lamb modes. We end up with 3d mixed elastic elements, which are referred to as tangential-displacements and normal-normal-stresses (TD-NNS), recently proposed and analyzed by Astrid Pechstein (born Sinwel) and Joachim Schöberl at TU Vienna. We show that these new elements cover the whole spectrum of elastic waves including higher-order Lamb waves. Finally, relying on TD-NNS finite elements and a Newmark time discretization scheme we present simulations of interaction of ultrasonic waves with cracks.
