The effects of peer teaching on the university students achievements in cognitive, affective, psychomotor domains and game performances in volleyball courses

This study is related to one of the teaching models, peer teaching which is used in physical education courses. The fundamental feature of peer teaching is defined “to structure a learning environment in which some students assume and carry out many of the key operations of instruction to assist other students in the learning process”. The aim of this study was to examine the effects of peer teaching on the university students' achievements in cognitive, affective, psychomotor domains and game performances in volleyball courses. The quasi-experimental design was used in this study. The study involved seventy second and third grade students at Abant Izzet Baysal University (AIBU), the School of physical education and sport. The sample consisted of 46 males (% 65.7) and 24 females (%34.3) from the department of teaching physical education and department of coaching education. The data was collected by means of the volleyball achievement test, volleyball skills observation forms, attitudes towards volleyball course scale and game performance assessment instrument. The 3x2 (Treatment condition: experimental I, experimental II and control x Time: Pre/Post test) repeated measure analysis of variance and one way analysis of variance were used to analyze the data. Findings indicated that there was a significant time X group interactions for cognitive domain. The same age peer teaching group improved their cognitive scores over a time more than CWPT-PE group. On the other hand, there were no significant time X group interaction effects in psychomotor, affective domains and game performances. According to the results of the study, it can be concluded that using different instructional models in volleyball classes improved students’ achievement in cognitive, psychomotor domains and game performance but not affective domain. The present findings mean that at the university level, both teacher centered and students centered teaching have similar effectiveness in domains of learning in volleyball course. Key words: Peer teaching, cognitive domain, affective domain, psychomotor domain, game performance, volleyball.
Replication of a herpes-like virus in larvae of the flat oyster Tiostrea chilensis at ambient temperatures

Veligers removed from brooding T~ostrea chilens~s (Philippi, 1845) experienced -95% mortalities over 3 to 4 d at 16 to 18°C that appeared to be associated with a herpes-like virus. Ultrastructural observations of post-removal veligers showed the presence of early viral replication or putative latent stages at 4 h, all stages of replication at low levels at 24 h, which increased to high levels at 48 h, followed by mortalities at 72 h onwards. Initially, infected interstitial or epithelia1 cells had an enlarged nucleus with a wavy outline in which heterochromatin was marginated. With continued increase in size, nuclei became smooth in outline with reduction or loss of heterochromatin. Capsids with lucent cores (LCC) and empty capsids appeared in the nucleus, often in association with tubular structures -65 nm in diameter that were composed of subunits in a helical configuration that contained a tubular core -35 nm in diameter. Empty capsids and LCC sometimes occurred in paracrystalline arrays. Partial nucleolar disaggregation and encapsidation of dense fibrillar material preceded envelopment entering and de-envelopment leaving the perinuclear cisterna, tegumentation in cytoplasmic vesicles, and egress. Groups of dense cytoplasmic filaments 30 to 35 nm in diameter occurred in some infected cells. Apparently normal cells with a few intranuclear empty capsids and/or LCC at 4 h postremoval may represent latent infections. Replication was not observed in larvae held at 24 to 27'C. but a few cells had enlarged hypochromatic karyolytic nuclei, and 1 to 2 capsids were observed in them, at 48 h. Viral replication was similar to that of ranid herpesvirus 1 (Lucke tumour) infections. This is the fifth ostreid species from which herpesviruses have been reported.
RELAY PLANTING OF WHEAT IN COTTON: AN INNOVATIVE TECHNOLOGY FOR ENHANCING PRODUCTIVITY AND PROFITABILITY OF WHEAT IN COTTON–WHEAT PRODUCTION SYSTEM OF SOUTH ASIA

SUMMARY Cotton–wheat (CW) is the second most important cropping system after rice–wheat in South Asia. Sowing of wheat after cotton is usually delayed due to late pickings coupled with time needed for seedbed preparation, resulting in low wheat yield. Lack of suitable machinery is a major constraint to direct drilling of wheat into the heavy cotton stubbles. An innovative approach with much promise is the ‘2-wheel tractor-based self-propelled relay seeder’ with seed-cum-fertilizer attachment. On-farm trials were conducted at four locations during 2009–2010 and at 10 locations during 2010–2011 to evaluate the following four wheat establishment methods in CW-dominated areas of south-western Punjab, India: (1) zero till seeding in standing cotton using a self-propelled relay seeder, (2) relay seeding in standing cotton with a manual drill without prior tillage (2010 only), (3) relay broadcast seeding in standing cotton following light manual tillage and (4) conventional sowing of wheat after cotton harvest (conventional tillage and sowing with a seed–fertilizer drill). Planting of wheat under conventional practice was delayed by 20–44 days compared with relay seeding. Seed cotton yield was also significantly higher with relay seeding due to opportunity for one additional picking. Yield of wheat sown with the self-propelled relay seeder was 41.2% and 11.8% higher than with conventional practice in 2009–2010 and 2010–2011 respectively. The increase in wheat yield under relay seeding of wheat was primarily due to higher spike density and more grains per spike. The net income from the CW system was 28.2% higher for the self-propelled relay seeder than with conventional sowing.

Discovering COX-2 Inhibitors from Flavonoids and Diterpenoids -

Article history: Received on: 21/11/2016 Accepted on: 06/01/2017 Available online: 30/07/2017 Cyclooxygenase is the enzyme that catalyzes the biosynthesis of prostaglandins from its substrate, arachidonic acid (AA). The reactions involve two steps which are (1) the oxidation of AA to the hydroperoxyendoperoxide PGG2, followed by (2) its subsequent reduction to the hydroxyl endoperoxide PGH2. Selective COX-2 inhibitors do not bind to Arg120, an amino acid residue used by AA and by the nonselective NSAIDs, all of which are carboxylic acids. In this work we studied the interaction of 54 compounds against COX enzymes for antiinflammatory discovery using molecular docking simulation. Docking simulation for each compound was repeated 100x using Linux script command for AutoDockVina embedded in MGLTools v.1. 5.6. Discovery Studio v.2. 5.5 was employed to predict the volume of both COX binding pockets.21 compounds were selected according to their best scoring values and were calculated their selectivity index (cSI). Selective COX-2 inhibitors, respectively, are (1) 3,19-O-diacetylandrographolide; (2) 2-((1R,4aS,5R,6R,8aS)-6-hydroxy-5(hydroxymethyl)-5,8a-dimethyl-2 methylene decahydronaphthalen-1-yl)-1-(2-oxo-2,5-dihydrofuran-3-yl) ethyl 4-methylbenzoate; and (3)12,13-dihydroandrographolide. Preferential COX-2 inhibitorsare (1) coronarin D; (2) 19-O-acetylhydroandrographolide; (3) p-methoxycinnamic acid; (4) kaempferide. The rest of the ligands are categorized as non-selective inhibitors.
Assessment of microbial load in marketed broiler meat at Mymensingh district of Bangladesh and its public health implications

An investigation was conducted to assess the bacteriological quality of 30 samples of fresh broiler thigh meat samples sold in different retail markets in Mymensingh. Total viable count (TVC), total coliform count (TCC), total salmonella count (TSC) and total campylobacter count (TCpC) in meat samples of different broiler markets like K.R. at BAU campus, Boyra and Kewatkhali were determined. Mean of TVC, TCC, TSC and TCpC for the K.R. at BAU campus, Boyra and Kewatkhali markets were 5.69, 6.03, 6.17 log 10 CFU/g, 4.52, 4.66, 4.69 log10 CFU/g, 3.35, 3.51, 3.61, log10 CFU/g and 2.31, 2.56, 2.66 log10 CFU/g, respectively. It was observed that the mean values of TVC, TCC, TSC and TCpC in case of Boyra and Kewatkhali market exceeded the ICMSF recommendations which may cause alarm to consumers health. The variation of TVC in meats of different broiler market was significant (P 0.05). The mean values of TCpC in meats of three different market were highly significant with 1% level of probability (P 0.05), but a significant correlation found between TVC with TSC and TVC with TCpC in meats of three different markets respectively. Presence of Escherichia coli, Campylobacter and Salmonella spp. in meats must receive particular attention, as these organisms are responsible for causing harm to public health. Suggestion has been given to improve the present sanitary condition of meat processing to minimize bacterial load. Res. Agric. , Livest. Fish.2(1): 87-95, April 2015
Deferoxamine-induced high expression of TfR1 and DMT1 enhanced iron uptake in triple-negative breast cancer cells by activating IL-6/PI3K/AKT pathway

Background: Deferoxamine (DFO) is a commonly used iron chelator, which can reduce the iron levels in cells. DFO is normally used to treat iron-overload disease, including some types of cancer. However, our previous studies revealed that DFO treatment significantly increased the iron concentrations in triple-negative breast cancer cells (TNBCs) resulting in enhanced cell migration. But the mechanism of DFO-induced increasing iron uptake in aggressive TNBCs still remained unclear. Materials and methods: Iron metabolism-related proteins in aggressive breast cancer MDA-MB-231, HS578T and BT549 cells and nonaggressive breast cancer MCF-7 and T47D cells were examined by immunofluorescence and Western blotting. The possible regulatory mechanism was explored by Western blotting, co-incubation with neutralizing antibodies or inhibitors, and transwell assay. Results: In this study, we found that DFO treatment significantly increased the levels of iron uptake proteins, DMT1 and TfR1, in aggressive TNBCs. Moreover, both TfR1 and DMT1 expressed on cell membrane were involved in high iron uptake in TNBCs under DFO-induced iron deficient condition. For the possible regulatory mechanism, we found that DFO treatment could promote a high expression level of IL-6 in aggressive MDA-MB-231 cells. The activated IL-6/PI3K/AKT pathway upregulated the expression of iron-uptake related proteins, TfR1 and DMT1, leading to increased iron uptakes. Conclusion: We demonstrated that DFO could upregulate expression of TfR1 and DMT1 , which enhanced iron uptake via activating IL-6/PI3K/AKT signaling pathway in aggressive TNBCs.
Complex Prophylaxis and Prognosis of Inflammatory Complications after Dental Implantation

Aim and Scope: The main task of dental implantation at the modern stage of its development remains the struggle against complications. At present, there is no generally accepted set of biomarkers and an algorithm for their use for early diagnosis of the risk of complications and monitoring of osseointegration. The objective of the study is to increase the effectiveness of dental implantation by developing a method of complex prophylaxis and prediction of development of complications in the long-term perspective after the operation. Materials and Methods: A method of preventing the development of complications of dental implantation by applying a complex of antioxidant vitamins and amino acids was approved and introduced. Results and Discussion: The significance of serum and local indices of the cytokine profile as diagnostic and prognostic parameters in patients with peri-implantitis developed afterthe operative intervention, was determined. It was found that patients with simultaneous installation of 5 or more implants, in spite of competent surgical work, are at higher risk of complications development in the long-term due to the presence of peculiarities of the mediator reaction with the prevalence of local inflammation processes. Conclusion: Perhaps a promising direction of prevention in the future will be the development of methods for targeted delivery of antioxidant substances to tissues to fill the deficit of protective components and establish an equilibrium.

YOUTH ENVIRONMENTAL COMPLAINTS IN BAHAWALPUR CITY, PAKISTAN: AN INFORMATIONAL INTERVENTION FOR LOCAL ENVIRONMENTAL GOVERNANCE

The paper comprises the concept of environmental governance, and the role played by institutions and citizens particularly youth dealing with environmental problems complaints. It represents an initial attempt to construct a fresh approach to the field of environmental governance by considering youth complaints as an important source of information for the management authorities. Local organizations and institutions are considered in order to collect information about the number and types of complaints regarding environmental problems. Moreover, the resolved and unresolved complaints data is also collected through Tehsil Municipal Administration complaints cell and particular actions are analysed. The complaints submitted by citizens are categorized on the basis of age structure. Results clearly show the interest of youth regarding environmental problems as well as the local authorities response of these complaints are recorded in the through textual interviews results. The submitted complaints made it very easy for the authorities to analyse the environmental problems at union council level and resolved complaints shows the attention of local authorities towards these problems. Youth as being educated and most active part of the community can play its vital role in this process. Youth, by its participation can make this complaint process an important avenue for community participation in environmental governance and policies. The paper tries to build a new idea about youth involvement by analysing their interests in the city related environmental problems. It gives an approach of developing collaboration between youth community and municipality for better planning concerning the problems of the city.
Value‐driven Internet shopping: The mental accounting theory perspective

When faced with competition and the ease with which customers can compare prices across sellers, Internet vendors often lower prices in a bid to increase sales. However, recent research reports that even price-sensitive customers do not always purchase from Internet vendors offering the lowest prices. In contrast, value has been considered a key motivator of customer decision making in economics and marketing. However, little is known about the role and effect of value in Internet shopping. This study examines online customer purchase decision making from the value perspective based on mental accounting theory. This study also identifies monetary (perceived price) and non-monetary (perceived risk, convenience, and pleasure) determinants of value. This study further explains how the individual determinants affect online purchase decision making directly and indirectly though value perception. The findings of this study offer Internet vendors practical suggestions for increasing online sales. This study, with its results, also helps advance knowledge of electronic commerce. © 2009 Wiley Periodicals, Inc.
Optimization of Flow Channel Design and Operating Parameters on Proton Exchange Membrane Fuel Cell Using MATLAB

Operating parameters like pressure, temperature, the stoichiometric ratio of reactants, relative humidity and design parameters like rib width to channel width (L:C), the shape of the flow channel and the number of passes on the flow channel are influencing the performance of the Proton Exchange Membrane Fuel Cell (PEMFC). In this paper, optimization of operating and design parameters such as pressure, temperature, inlet reactant mass flow rate and various rib width to channel width (L:C) 1:1, 1:2, 2:1 and 2:2 on serpentine and interdigitated flow channel of 25cm2 active area of the PEMFC was considered. Creo Parametric 1.0 and CFD Fluent 14.0 software packages were used to create the 3 Dimensional (3- D) model and simulation of PEMFC. The optimization was carried out on the various parameters with MINITAB 17 software and MATLAB software. From the first stage, the Landing to channel width (L: C) - 1:1 of serpentine and the interdigitated flow channel has the maximum influence on fuel cell performance and square of response factor (R2) was achieved from the Taguchi method by MINITAB 17 software as 99.48 and 99.71 % respectively. In the second stage, the regression equation or mathematical model obtained from MINITAB 17 software were fed into the MATLAB software to get optimized parameters. Further the power densities were obtained corresponding to the optimized parameters using the CFD Fluent 14.0 software.
Therapeutic Norms and Patient Benefit: Cancer Patients in Professionally Directed Support Groups.

Author(s): lieberman, morton a | Abstract: This study examines the relationship between cancer support groups’ normative regulation and patient outcomes. Cancer patients (N 289) in 54 groups were studied through the use of a cross-sectional, treatment dosage design. Outcomes were assessed by the Center for Epidemiological Studies Depression Scale and the Functional Assessment of Cancer Therapy, a quality of life measure commonly used in studies of cancer patients. The framework for assessing normative regulations was based on the degree to which patients matched leader norms. This approach to indexing members’ perceptions of normative regulations proved to be a successful strategy. The more a participant view matched those of the leaders, the greater the likelihood they benefited from the group. The content of the norms added an independent effect on positive outcomes. Participants who saw their groups as approving of aggressive– competitive behaviors and the intense expression of emotions were less likely to show positive outcomes.
The creation view of opportunities at the base of the pyramid

This research aims to understand how multinational corporations (MNCs) enter the base of the pyramid (BoP) by adopting the creation view of opportunities. We employ actor–network theory and explore the key actors, the process and the opportunity development that enable MNCs to tackle the relative poverty of the BoP market. Our qualitative exploratory case study illustrates that, at the BoP, MNCs have to involve beneficiary stakeholders such as non-governmental organizations and BoP communities. In this process, they should be open to modifying their business model continuously to build awareness about the product among the poor and ensure affordability, availability and acceptability. At the BoP, opportunities do not exist in the external environment and they should be developed by identifying and addressing the real needs of the poor, enhancing their quality of life and being patient about earning a profit. This research contributes to the entrepreneurship literature by expanding the creation perspective of opportunities and provides implications for the managers of companies targeting the BoP market.
Echocardiographic Findings in Children with Chronic Kidney Disease as Seen in a Resource -Limited Setting

Background: Echocardiographic detectable cardiac abnormalities were studied to provide a platform for future longitudinal and interventional studies of children with Chronic Kidney Disease (CKD) in the south- east region of Nigeria. Methods: A cross-sectional study of echocardiographic screening of children aged between 6 and 17 years with CKD and selected age and sex matched controls that were consecutively enrolled from the Pediatric nephrology clinic of the University of Nigeria Teaching Hospital (UNTH), Enugu, Nigeria. Results: Of the 9,419 patients within the age group 6-17 years who were seen at UNTH during the period of the study, 24 had CKD, giving an incidence of approximately 5 new cases per million-child population per year and a prevalence of 18.4 per million children population with a mean age of 12.33 + 4.24 years. Lower mean ejection fraction (EFrac%) values and E/A (transmitral flow velocity ratio) ratio were documented in patients compared to controls (p<0.01). Echocardiographic detectable cardiac abnormalities occurred in 22 (91.7%) of the patients and in 4 (16.7%) of the controls (p<0.01). The most common abnormality was left ventricular hypertrophy in 12 patients (50.0%) with 8 (66.6%) of 12 children having eccentric and 4 (33.3%) having concentric hypertrophy. Conclusions: This study shows that echocardiographic detectable cardiac abnormalities in children with CKD in the sub-region, is comparable to those of the other parts of the world with eccentric hypertrophy being more prevalent than concentric hypertrophy.
