Abstract One of the most effective tools in e-learning is the Self-Assessment Tool (SAT) and research has shown that students need to accurately assess their own performance thus improving their learning. The study involved the design and development of a self-assessment tool based on the Revised Blooms taxonomy Framework. As a second step in investigating the effectiveness of the SAT, 1st year student of the BSC Educational Technology program from the VCILT, University of Mauritius were used as testing sample. At this stage the SAT was provided to only half of the sample who were randomly chosen and placed into a treatment group. The remaining half (Control Group) had the normal conditions on the E-learning platform. A semester exam was devised and administered to the whole sample to find out if there was a difference between the scores of both groups. Lastly a feedback form was given to only the treatment group to find out their views on the SAT. The results indicated a significant difference in scores between the treatment and the control groups when the Student’s Independent T-test was used. Group A percentage of passes were higher compared to Group B. Failures were recorded for both groups with an increased rate of failure for Group B compared to Group A. Moreover, most of the respondents’ feedbacks suggested that SAT was a useful guide with helpful feedbacks. The findings concluded that SAT was viewed more as a revision tool that allowed them to assess their own learning.

This experiment was conducted to determine the effect of papaya leaf (Carica papaya) and kalo jeera (Nigella sativa) seeds powdered supplementation in drinking water as a growth promoter in broiler chickens. A total of 20 Cobb-500 broiler chicks (day-old) were purchased from local hatchery (Nourish Poultry and Hatchery Ltd.) and after seven days of acclimatization chicks were randomly divided into two groups, A (n=10) and B (n=10). The group A was kept as a control and not treated. The group B was supplemented with papaya leaf and kalo jeera powder with feed and water. Weekly observations were recorded for live body weight gain up to 5th weeks and hematological tests were performed at 35th day’s age of broiler to search for hematological changes between control (A) and treatment (B) groups. The initial body weight of groups A and B on 1st were 41.00±0.56 gm and 41.50±0.35 gm, respectively and after 35th day of experiment final body weight were 1470±57.35 gm and 1720±58.56 gm, respectively and economics of production were analyzed and found that net profit per broiler was Tk. 8.91 and Tk. 20.69, respectively. The treatment group B was recorded statistically significant (at 1% level) increased (17.00%) for live body weight than that of control group A. The hematological parameters total erythrocyte count (TEC), erythrocyte sedimentation rate (ESR) and hemoglobin (Hb) estimation value of treatment group shows significant difference, while hemoglobin estimation does not show significant difference from control group. The results suggest that better growth performance could be achieved in broilers supplemented with papaya leaf and kalo jeera seeds.

<p>The current study focuses on the importance of integrating peer- and self-assessment in<br />teaching English as a second/foreign language in Saudi Arabia. It pays special attention to the<br />mechanisms by which Saudi EFL learners can improve their English writing skills if they<br />engage in peer- and self-assessment regularly. To this end, the researcher administered a<br />writing composition task to measure the participants’ ability to express themselves in good<br />English, focusing on the coherence, cohesion, word choice, spelling, punctuation, and layout<br />of their essays. The researcher utilised the experimental two-groups design of a pre-test and a<br />post-test, in order to evaluate the participants’ performance prior to the application of the<br />treatment (i.e. peer- and self-assessment) and after it. For the purpose of the study, the<br />participants were divided into two groups: students in group A (i.e. the treatment group)<br />engaged in peer- and self-assessment regularly throughout the term, whilst students in group<br />B (i.e. the control group) did not. The results of group A on the pre-test and post-test were<br />compared to those of group B to determine whether the treatment had any impact on their<br />performance. The results reveal that group A outperformed their group B counterparts on the<br />post-test. The statistical analysis demonstrates that the difference between the results of the<br />two groups was statistically significant, suggesting that the treatment contributed positively to<br />the performance of the treatment group. Finally, the study concludes with recommendations<br />for further research.</p>

Lipopolysaccharide (LPS) is an endotoxin from the outer membrane of Gram-negative bacteria, which has an important role in the occurrence of sepsis. Exposure to LPS will stimulate increase of nitric oxide (NO). Nitric oxide is a bioregulator of apoptosis and has some sepsis prognostic role of apoptosis regulators within the gastrointestinal cells. The objective of the study is to know if endotoxemia induces an increase in NO levels and histopathology scores as well as the existing relationship between them. This study is an observational intervention. The subjects were 48 male mice Balb/C, divided into 2 groups. The samples consisted of 24 tail as control group (group A) and 24 as treatment group (group B). The A group as well as the B group is divided into 4 subgroups according to the time of termination. The levels of NO were examined by Griess method. Histopathology score was examined by HE and read as a score of 0–5. There was a statistically significant difference between the mean NO in the treatment group with the control group at the termination of the group of 12h (p=0.009), 24h (p=0.015), 36h (p=0.014), 48h (p=0.002) and the whole group (p=0.0001), as well as between the mean histopathology score at the termination time of 12 h (p=0.0001), 24h (p=0.0001), 36h (p=0.0001), 48h (p=0465) and the whole group (p=0.0001). Increase in NO and histopathology scores in all groups of mice (r=0.527) showed a statistically significant correlation. NO levels and histopathology scores are increased during endotoxemia and thus have a significant correlation.

This experiment was conducted to investigate the efficacy of tulsi leaves (Ocimum sanctum) extract supplementation in drinking water as a growth promoter in broiler chickens. A total No. of 30 day old Cobb-500 broiler chicks was purchased from local hatchery and after seven days of acclimatization chicks were randomly divided into two groups A and B in equal number. The group A was kept as a control and not treated. The group B was supplemented with tulsi leaves extract with feed and water. Weekly observations were recorded for live body weight gain up to 30 days and hematological tests were performed at 30th day’s age of broiler to evaluate the hematological changes between two groups. The initial body weight of groups A and B on 1st day of this experiment were 42.80±10.31 gm and 42.68±6.90 gm respectively and after 30th days of experiment final body weight were 1530± 33.07 gm and 1600± 44.80 gm respectively; the net body weight gain from 7th day were 1488±41.12 gm and 1551±39.29 gm respectively and economics of production was analyzed and found that net profit per broiler was Tk. 24.51 and Tk. 32.50 respectively. The treatment group B was reported statistically significant (at 1% level) increased 16.43% for live body weight than the control group A. The hematological parameters TEC, ESR and PCV value of treatment group showed significant difference, while Hemoglobin (Hb) estimation did not show significant difference from control group. Therefore, the findings of the study results suggest that supplemented with tulsi leaves extract with feed and water can improve the growth performance of broiler.

Background: Ankle sprains are a frequently occurring injury sustained by sports individuals accounting for approximately 20% to 40% of all sports injuries (DiStefano et al. 2008; LeBrun and Krause, 2005). Ankle sprains are mainly caused by excessive inversion (Takao et al., 2005; Andersen et al., 2004), when the foot is twisted inwards and lands at a high velocity damaging the lateral capsule-ligamentous complex (Beynnon et al., 2005). According to Naqvi, Cunningham and Lynch (2012) untreated or inappropriately managed ankle sprains can lead to a cascade of negative alteration to both the joint structures and the individual’s lifestyle. According to Hale, Hertel and Olmsted-Kramer (2007) 30% of ankle sprains result in chronic ankle instability (CAI) and 78% of the CAI cases develop into post-traumatic ankle osteoarthritis. This poses a negative impact on an individual’s athletic performance. Ankle sprains can be managed conservatively with the utilization of the PRICE protocol during the acute stage, cross friction massage or instrument assisted soft tissue mobilization techniques (for example Graston®, FAKTR© Concept) for both acute and subacute ankle sprains (Bleakley, 2010). Aim: The purpose of this study was to determine the effectiveness of a myofascial treatment protocol (FAKTR© Concept) combined with cryotherapy compared to cryotherapy and sham laser in the treatment of sub-acute and acute ankle inversion sprains. Objectives: 1. To determine the effectiveness of a myofascial treatment protocol combined with cryotherapy in terms of subjective (numerical pain rating scale [NRS] and foot function index [FFI]) and objective (oedema measurements [EDM], digital inclinometer readings [DIR], algometer readings [AR] and stork balance stand test score [STR]) measurements in the treatment of acute and sub-acute ankle sprains. 2. To determine the effectiveness of sham laser combined with cryotherapy in terms of subjective (NRS and FFI) and objective (EDM, DIR, AR and STR) measurements in the treatment of acute and sub-acute ankle sprains. 3. To compare the relative improvement between the two groups in terms of subjective (NRS and FFI) and objective measurement (EDM, DIR, AR and STR). Study design: This was a quantitative randomised controlled clinical trial. Methods: Forty participants with sub-acute or acute ankle sprains of not more than three weeks were recruited into the study. All participants had a full case history, physical, and foot and ankle regional examination to assess for their eligibility for entry into the study in terms of inclusion and exclusion criteria. These participants were randomly allocated using the hat method into one of two study groups, Group A (treatment group) or Group B. Participants in Group A received a myofascial treatment protocol (FAKTR© Concept) combined with cryotherapy and Group B received cryotherapy and sham laser. These participants had four treatments in two weeks where the appropriate treatment was administered. Pre-treatment subjective (NRS and FFI) and objective (EDM, DIR, AR and STR) measurements were taken at each consultation. This data was analysed using SPSS software version 24.0. Results: The General Linear Model for repeated measures was used for the intra- group and inter-group analysis of the data. Intra-group analysis of the FAKTR© treatment group showed that the group had statistically significant improvements in terms of the subjective and objective measurements of the study with the p-value < 0.05 between all treatment periods. Intra-group analysis of the control group showed no statistically significant improvements in terms of subjective and objective measurements of the study. Inter-group analysis showed no statistically significant difference in terms of the DIR and EDM. The NRS, AR, STR and FFI readings showed statistically significant differences between the two groups with a p-value of < 0.05 mainly on the last two consultations. Conclusion: This study concluded that the myofascial treatment protocol (FAKTR© Concept) combined with cryotherapy was more effective than cryotherapy and sham laser in the treatment of sub-acute and acute inversion ankle sprains. The FAKTR© Concept treatment group appeared to show statistically significant improvements compared to the control group.

The quest for excellence in mental and physical health is not new. We find various references and formulations in Ayurvedic classics meant for promoting mental and physical health of a child. Suvarna Prashan is one of the formulations explained in age old Ayurvedic classic Kashyap Samhita. This formulation is very widely used now days as a memory and immune booster for children. But there is very little systematic documented study which can be used to evaluate the efficacy of the formulation. Suvarna Bhasma was prepared in Ayurved Rasayani Pharmacy, Pune. Madhu and Ghrita were collected from KLE Ayurveda Pharmacy, Belgaum. Suvarna Bindu Prashan was prepared in KLE Ayurved pharmacy, Belgaum. It contains Suvarna Bhasma, Ghrita and Madhu. Twenty apparently healthy male and female children with age group of three to four years were ready to sign inform consent form were selected into two groups each. Subjects in Group A received Suvarna Bindu Prashan where as Group B (Control group) did not receive any treatment. Both the groups were observed for six months. Children in Suvarna Bindu Prashan group showed significant reduction in the scores of eating habits, behavior, mood, temperament and scores of event of illness. However there was no significant difference in the score of sleeping habit. There was significant increase in IQ percentage.

Objective: To evaluate the effectiveness of placing a resorbable collagen barrier in impeding the extrusion of obturation material in primary molars undergoing resorption. Study design: All the 94 canals in 47 mandibular molars were allocated to 2 groups- Group ‘A’- 47 canals with collagen barrier (Test group) and Group ‘B’- 47 canals without collagen barrier (Control group) based on randomization protocol. Pulpectomy was performed and obturation of both test and control canals were radiographically assessed. Pearson’s chi – square test was applied to analyze the results. The significance level was predetermined at p &lt; 0.05. Results: Among the test group, 93.6% of the canals showed no extrusion while, 6.4% showed visible extrusion of the material outside the apex. In the control group, 83% showed no extrusion whereas 17% of the canals showed visible extrusion outside the apex. But no significant difference was noted (p&gt;0.05). Conclusion: The placement of resorbable collagen barrier in the apical third of the canal prevented the extrusion of obturating material beyond the apex in resorbing primary molars.

OBJECT The use of digital subtraction angiography (DSA) for semiquantitative cerebral blood flow(CBF) assessment is a new technique. The aim of this study was to determine whether patients with aneurysmal subarachnoid hemorrhage (aSAH) with higher Hunt and Hess grades also had higher angiographic contrast transit times (TTs) than patients with lower grades. METHODS A cohort of 30 patients with aSAH and 10 patients without aSAH was included. Relevant clinical information was collected. A method to measure DSA TTs by color-coding reconstructions from DSA contrast-intensity images was applied. Regions of interest (ROIs) were chosen over major cerebral vessels. The estimated TTs included time-to-peak from 0% to 100% (TTP0–100), TTP from 25% to 100% (TTP25–100), and TT from 100% to 10% (TT100–10) contrast intensities. Statistical analysis was used to compare TTs between Group A (Hunt and Hess Grade I-II), Group B (Hunt and Hess Grade III-IV), and the control group. The correlation coefficient was calculated between different ROIs in aSAH groups. RESULTS There was no difference in demographic factors between Group A (n = 10), Group B (n = 20), and the control group (n = 10). There was a strong correlation in all TTs between ROIs in the middle cerebral artery (M1, M2) and anterior cerebral artery (A1, A2). There was a statistically significant difference between Groups A and B in all TT parameters for ROIs. TT100–10 values in the control group were significantly lower than the values in Group B. CONCLUSIONS The DSA TTs showed significant correlation with Hunt and Hess grades. TT delays appear to be independent of increased intracranial pressure and may be an indicator of decreased CBF in patients with a higher Hunt and Hess grade. This method may serve as an indirect technique to assess relative CBF in the angiography suite.
