Development of decellularized meniscus using closed sonication treatment system: potential scaffolds for orthopedics tissue engineering applications

Purpose Meniscus is a fibrocartilagenous tissue that cannot effectively heal due to its complex structure and presence of avascular zone. Thus, tissue engineering and regenerative medicine offer an alternative for the regeneration of meniscus tissues using bioscaffolds as a replacement for the damaged one. The aim of this study was to prepare an ideal meniscus bioscaffold with minimal adverse effect on extracellular matrix components (ECMs) using a sonication treatment system. Methods The decellularization was achieved using a developed closed sonication treatment system for 10 hrs, and continued with a washing process for 5 days. For the control, a simple immersion treatment was set as a benchmark to compare the decellularization efficiency. Histological and biochemical assays were conducted to investigate the cell removal and retention of the vital extracellular matrix. Surface ultrastructure of the prepared scaffolds was evaluated using scanning electron microscope at 5,000× magnification viewed from cross and longitudinal sections. In addition, the biomechanical properties were investigated through ball indentation testing to study the stiffness, residual forces and compression characteristics. Statistical significance between the samples was determined with p-value =0.05. Results Histological and biochemical assays confirmed the elimination of antigenic cellular components with the retention of the vital extracellular matrix within the sonicated scaffolds. However, there was a significant removal of sulfated glycosaminoglycans. The surface histoarchitecture portrayed the preserved collagen fibril orientation and arrangement. However, there were minor disruptions on the structure, with few empty micropores formed which represented cell lacunae. The biomechanical properties of bioscaffolds showed the retention of viscoelastic behavior of the scaffolds which mimic native tissues. After immersion treatment, those scaffolds had poor results compared to the sonicated scaffolds due to the inefficiency of the treatment. Conclusion In conclusion, this study reported that the closed sonication treatment system had high capabilities to prepare ideal bioscaffolds with excellent removal of cellular components, and retained extracellular matrix and biomechanical properties.
Pyometra in Bitches: A Review of Literature

Pyometra is a frequently diagnosed bacterial infection of the uterus in intact, sexually mature bitches, leading to the accumulation of purulent material in the uterine lumen. Approximately one third of the anoestrous bitches can be diagnosed with pyometra. Closed-cervix pyometra is particularly dangerous, because septicaemia and toxaemia may develop rapidly and if left untreated can result in death of the patient. Due to the insidious nature of the disease and its sometimes equivocal clinical signs, patients are often presented in poor condition for anaesthesia and surgery.

Knowledge , attitude and practices of mothers of under-five children about Rotavirus diarrhoea and vaccine in a tertiary-care hospital of Northeast India

Original Research Article Childhood diarrhoea is one of the leading causes of hospitalization and death among under-five children. Rotavirus is one of the most important causes of severe diarrhoea because it has a propensity to cause rapid dehydration. Also, the profound vomiting that occurs in rotavirus-caused diarrhoea limits the scope of oral rehydration therapy. Vaccines are now being introduced in immunization schedules in a phased manner over the country. A descriptive, cross-sectional study was done to assess the level of knowledge of mothers about rotavirus and various attitudes and practices regarding its vaccination in a tertiary-care hospital of Northeast India. Convenience sampling technique was employed to interview 700 mothers of under-five children using a pre-designed, structured interview format. Descriptive statistics and suitable tests like Chi-square test were used to ascertain association between variables. A P-value < 0.05 was considered statistically significant. Only about 2% of the total respondent mothers knew about the rotavirus and the vaccine. And among them, about half had satisfactory knowledge. The association of knowledge with educational level, occupation and age of the respondent’s child was found to be statistically significant. Though the government’s initiatives in introducing the vaccine in the national immunization schedule are definitely laudable, dissemination of information about its importance needs to be scaled using health education activities to improve the general awareness of the disease and acceptability of the vaccine.
Highly attractive models in advertising : What causes negative affect ?

Highly attractive models (HAMs) have been popularly used in advertising to exert psychological impacts on the message receiver in the hope of increasing advertisement’s effectiveness. The marketing literature is replete with evidence of the positive effects of using HAMs. However, support for their effectiveness is somewhat conflicted. The research attempts to add to the body of general knowledge, specifically through exploring the impact of individual difference variables (model characteristics, product types, comparison motives and culture) on negative effects. This study also investigates whether advertising skepticism determined by culture has an impact on negative effects as a result of a HAM comparison. The methodology uses a 3 [beauty types] x 2 [product types] x 2 [comparison motives] between-subjects experimental design. Respondents for the main study are female students across cultures from international programs and universities in Vietnam. The results supported all hypotheses; except product types shown having no impact on negative effects. The research also confirmed there are interrelationships between culture and skepticism. These findings have implications regarding the potentially negative influence of advertising including HAMs for practitioners, academics and public policy makers.
Automated written corrective feedback: how well can students make use of it?

ABSTRACT Automated written corrective feedback (AWCF) has qualities that distinguish it from teacher-provided WCF and potentially undermine claims about its value for L2 student writers, including disparities in the amounts of useful information it provides across error types and the fact that inaccuracies in error-flagging must be anticipated. It remains unclear how these factors influence different students’ ability to use AWCF, partly because classroom research to date has been based on within-group designs and writing tasks in which students can choose other ways to respond to feedback besides correction. To investigate these issues, the present study used an AWCF-based error-correction task in which student response type was controlled, as were the explicitness and accuracy of the feedback. Eighty-two ESL students in two, sequenced developmental writing courses participated. Generic feedback was found to result in fewer successful error corrections than specific feedback as well as higher perceptions of mental-effort expenditure and lower ratings of clarity and helpfulness. Course level was found not to be a significant factor in most analyses. Implications for L2 classroom applications of AWCF as well as the design of AWCF tools are discussed.
Dielectric Relaxation and Hopping Conduction in La 2 NiO 4 + δ

An ac conductivity as well as dielectric relaxation property of La 2 NiO 4.1 is reported in the temperature range of 77K–130K and in the frequency range of 20Hz–1MHz. Complex impedance plane plots show that the relaxation (conduction) mechanism in this material is purely a bulk effect arising from the semiconductive grain. The relaxation mechanism has been discussed in the frame of electric modulus spectra. The scaling behavior of the modulus suggests that the relaxation mechanism describes the same mechanism at various temperatures.The logarithmic angular frequency dependence of the loss peak is found to obey the Arrhenius lawwith the activation energy of∼0.09 eV.The frequency-dependent electrical data are also analyzed in the frame of ac conductivity formalism.The ac conductivity has been found to follow a power-law behavior at a limited temperature and frequency region where Anderson localization plays a significant role in the transport mechanism for La 2 NiO 4.1 .
3 D Bioprinting Human Induced Pluripotent Stem Cell-Derived Neural Tissues Using a Novel Lab-ona-Printer Technology

Most neurological diseases and disorders lack true cures, including spinal cord injury (SCI). Accordingly, current treatments only alleviate the symptoms of these neurological diseases and disorders. Engineered neural tissues derived from human induced pluripotent stem cells (hiPSCs) can serve as powerful tools to identify drug targets for treating such diseases and disorders. In this work, we demonstrate how hiPSC-derived neural progenitor cells (NPCs) can be bioprinted into defined structures using Aspect Biosystems’ novel RX1 bioprinter in combination with our unique fibrin-based bioink in rapid fashion as it takes under 5 min to print four tissues. This printing process preserves high levels of cell viability (>81%) and their differentiation capacity in comparison to less sophisticated bioprinting methods. These bioprinted neural tissues expressed the neuronal marker, βT-III (45 ± 20.9%), after 15 days of culture and markers associated with spinal cord (SC) motor neurons (MNs), such as Olig2 (68.8 ± 6.9%), and HB9 (99.6 ± 0.4%) as indicated by flow cytometry. The bioprinted neural tissues expressed the mature MN marker, ChaT, after 30 days of culture as indicated by immunocytochemistry. In conclusion, we have presented a novel method for high throughput production of mature hiPSC-derived neural tissues with defined structures that resemble those found in the SC.

Bir, A. , Benidir, M. , & Ikhlef, S. (2019). Sustainability analysis of dairy cattle farms and their susceptibility to climatic hazards in the semi-arid area of Setif (Algeria). Bulgarian Journal of Agricultural Science, 25(1), 3–9 In this study, the method of farm sustainability indicators (IDEA) was used to assess the sustainability of dairy cattle farms and their susceptibility to climatic hazards in three agro-bioclimatic stages of the semi-arid region of Setif (Algeria). Overall, the results show a high level of agro-ecological sustainability (56.24 points out of 100), acceptable for economic sustainability (54.36 points out of 100) and average for socio-territorial sustainability (52.31 points out of 100). The best sustainability performances were recorded at the farms of the North agro-bioclimatic stage, with 60.42 points out of 100 for the agro-ecological scale, 54.60 points out of 100 for the socio-territorial scale, 60.31 points on 100 for the economic scale and 51.21 points on 100 for agricultural sustainability. However, Southern agro-bio-climatic farms recorded the lowest scores of 49.82, 48.38, 46.71 and 41.97 points out of 100 respectively for the agro-ecological scale, socio-territorial scale, economic scale and agricultural sustainability.
THE CORRELATION BETWEEN TEACHERS ’ FRIENDLY ATTITUDE AND STUDENTS ’ SPEAKING ACHIEVEMENT

The research aims at finding out the correlation between teachers’ friendly attitude and students’ speaking achievement. The sample of this research was class VIII A consist of 35 students of SMPT Madinatul Ulum Cangkring Kecamatan Jenggawah, Jember. The research was a correlational research which was attempting to find out the correlation between two variables, teachers’ friendly attitude and students’ speaking achievement. The statistical description of the two variables was conducted before calculating the score into Pearson product moment formula. Based on the data analysis, it was found that rxy0.677 was higher than r table 0.349 with significant level 0.05 or 5 % and df 33. Therefore, if rxy was higher than r table, it can be concluded that there was a positive correlation between teachers’ friendly attitude and students’ speaking achievement. The correlation indicated a high-strong correlation between the two variables.
Edinburgh Explorer Redundancy Network Design for an Aircraft Door Management System

The door management system (DMS) is a safety system in an aircraft which checks if all doors are properly closed and the cabin is correctly pressurized. As for every critical system in an aircraft, it has to meet some safety regulations and it should be designed optimally in terms of weight, cost, or power consumption. This paper studies the problem of designing a DMS optimally as per the previous objectives while guaranteeing that there is redundancy, that is, the DMS is functional even if one of its components is not working. We call this new problem the DMS problem with redundancy. First, we propose a new MILP model for the DMS problem which includes redundancy, but the model turns out to be too diﬃcult to be solved eﬃciently. In order to improve computational performance, a specialized branching rule and a heuristic are proposed. Computational tests are run for example instances of the DMS problem by implementing these new rules in CPLEX. It could be seen that the solving time through the new branching rule and heuristic can be signiﬁcantly reduced.
Dependence Analysis of Public Higher Education Institutions in Uzbekistan 1

Since the early years of independence in 1991, a central topic of higher education in Uzbekistan has been how to fill the gap left by the reduced government funding at public higher education institutions (HEIs). The majority of the Uzbek universities, as in many other countries, have responded to the decline in public allocations through charging significantly increased tuition fees. Therefore, the revenue structure of public HEIs has changed from full government funding to mostly tuition funding over the last decade. Utilising resource dependence theory (RDT), this study empirically investigates whether or not increased institutional reliance on tuition fees as a main source of revenue has augmented the share of institutional expenditures dedicated to educational activities at public HEIs in Uzbekistan over the period 2000-2013. Drawing on a 14year panel of university-level data and employing an instrumental variable approach that acknowledges the potential endogeneity of institutional tuition revenue, the analysis suggests that institutional expenditures for educational expenses are considerably increased as institutions became more dependent on tuition revenue for their financially sustainable operation. This finding is consistent with the predictions of RDT. Robustness of the empirical findings is also checked utilising several diagnostic models, and the results revealed that the IVs applied during the TSLS estimations are valid and they simultaneously uncorrelated with the error term.
Developing an Accountability Disclosure Index for Malaysian State Islamic Religious Councils (SIRCS): Quantity and Quality Rosnia Masruki, Khaled Hussainey and Doaa Aly Academic Dishonesty among Accounting Students in Malaysia Salwa Hana Yussof and Suhaiza Ismail Financial Wellbeing of Single Mother

There are three objectives of the present study: to ascertain the types of assessment which are subject to cheating by accounting students; to determine the justifications given by students in neutralizing their cheating behavior; and to identify cheating deterrents from the perception of the students. A total of 435 questionnaires were collected from undergraduate accounting students of all levels of study in a public university in Malaysia. Findings revealed that more than half of the respondents had engaged in cheating, but mainly in quizzes and assignments that offer less weighting towards a final grade, and were subject to less monitoring and less severe punishment. As for neutralization, those who cheated had a tendency to blame instructors for their cheating behavior. In terms of deterrence, religion was cited most frequently as the factor that can deter students from cheating, particularly by continuous reminder that the God is always watching.
Educational Psychology THE RELATIONSHIP BETWEEN SOCIAL COMPETENCES AND COPING STRATEGIES IN CZECH UNIVERSITY STUDENTS

Social competences and the preference of coping strategies affect everyday functioning and dealing with demanding and stressful life situations, both in a general context and in the context of university study. The objective of this paper is to assess the relationship between these characteristics among university students. The Social Competences Inventory and the Coping Strategies Inventory (SVF-78) were used. The research sample consisted of 407 university students (average age = 26.38; SD = 7.09, range = 19-54, 114 males, 293 females). The results for the whole sample showed significant correlations between individual coping strategies and social competence scales, ranging from r = -. 467 to . 426 (explaining up to 22% of shared variance). Higher social competences generally increase the preference of avoidance and active control strategies and decrease escape strategies. Subsequent partial correlations and MANOVA test confirmed the impact of gender. Gender-related correlations revealed some differences in the strength and direction of the relationship. Male’s preference of coping strategies is affected mainly by the level of perceived masculinity, while female’s preference is more likely affected by their sensitivity to interpersonal functioning and by their social environment. An inference test confirmed significant differences of correlation coefficients between social orientation (control strategy) and reflexibility (negative strategy). The results suggest that interventions aimed at the development of social competences can positively affect the preference and use of desirable and effective coping strategies. © 2019 Published by Future Academy www.FutureAcademy. org.UK
Corynebacterium pseudotuberculosis primary infection in goats : kinetics of IgG and interferon-g production , IgG avidity and antigen recognition by Western blotting

Corynebacterium pseudotuberculosis is the cause of caseous lymphadenitis (CLA) in small ruminants, a chronic granulomatous disease that provokes significant zootechnics losses to ovine and goat breeders in northern Brazil. The present work was conducted to analyse aspects of humoral and cellular immune responses after experimental infection. Eight goats were infected intradermally with a single dose of virulent C. pseudotuberculosis strain and specific IgG, interferon-g (IFN-g) production as well as IgG avidity and antigens pattern recognition dynamics against an excreted–secreted antigen were recorded during 20 weeks. At the end of the follow-up, animals were slaughtered and necropsied. Although no animals showed apparent clinical signs of infection at the end of the trial, IFN-g response, even more so than the humoral response, differentiated animals into two groups of high or medium/low response. The time-course of IFN-g production presented a short-lived primary response on day 5 after infection of animals of both groups, and a strong and long lasting secondary response starting on day 16 after infection in the high response group. The indirect ELISA used was able to detect a positive antibody titre between 6 and 11 days after infection in the two groups. IgG avidity index oscillated initially between 15 and 45%, and showed approximately 5% units increment during the 20 follow-up weeks. With only one individual exception, the qualitative antigens pattern recognition showed on day 11 after infection remained constant through the experiment. IgG avidity is highly correlated with IgG production, but could not be related with specific immunodominant bands. Both humoral and cellular responses kinetics presented a similar pattern of activation/deactivation but necropsy results suggested that the IFN-g test would be a very specific marker of CLA status. # 2003 Elsevier B.V.

Risk assessment of indeterminate lung nodule characterization by a novel plasma-protein multiplexed assay in current smokers: Results of a clinical experience program

Background: To reduce overdiagnosis and overtreatment of non-cancerous pulmonary nodules found on chest imaging, an accurate non-invasive and easily administered test is needed to assist in the detection and diagnosis of cancers in a cost-effective manner at an early stage, when curative interventions are still possible. Objective: To assess the results of a novel, plasma-based multiplexed protein assay in a clinical experience program. Methods: Fifty-four consecutive plasma samples were evaluated in a CLIA-certified laboratory using the novel blood test. All samples were from patients who are current smokers, aged 25 years and older, and have an indeterminate pulmonary nodule 0.4 to 3 cm in diameter. Results: The mean patient age was 65.5 years and the mean nodule size was 1.0 cm. 26 patients were male (52% female). Of the 54 tests, the assay results for 23 individuals were determined to be in the lower risk of malignancy range (score ≤49). 42 patients had a pre-test probability in the intermediate risk range as calculated by the VA Clinical Model. Of those patients, the assay characterized 22 as having a lower risk of malignancy (52%). Conclusion: The risk stratification of individuals with an indeterminate pulmonary nodule appears to be enhanced by identifying benign nodules compared to current methods in clinical practice. We hypothesize patients with benign disease may benefit the most from this assay by avoiding unnecessary subsequent overtreatment such as lung biopsy or bronchoscopy, while improving patient quality of care and reducing associated risks and costs from these procedures. Providers and their patients in whom they suspect lung cancer may consider using this novel assay prior to proceeding with more aggressive interventions. *Correspondence to: Amanda L Fish, MagArray Inc, Milpitas CA, USA, E-mail: Amanda.Fish@magarray.com

Carbon nanotubes, mostly single- and double-walled, are prepared by a catalytic chemical vapor deposition method using H 2 - CH 4 atmospheres with different CH 4 contents. The maximum hydrogen storage at room temperatures and 10 MPa is 0.5 wt %. Contrary to expectations, purification of the carbon nanotube specimens by oxidative acid treatments or by heating in inert gas decreases the hydrogen storage. Decreasing the residual catalyst content does not necessarily lead to an increase in ASH. Moreover, increasing the specific surface area does not necessarily increase the hydrogen storage capacity. There seems to be a correlation between the pore volume at low pore diameters ( < 3 nm) and the hydrogen storage capacity. Contribution from nanoscale disordered carbon to the hydrogen storage cannot be ruled out.
