  Background and Purpose: Seafood makes up a significant portion of the diets of people around the world. Especially fatty fish such as salmon and herring, seafood items contain numerous nutritional benefits including omega-3 fatty acids which studies have shown aid in cognition and memory. However, due to natural and anthropogenic sources of pollution, contaminants such as mercury which studies suggest decreases cognitive functioning if consumed in excess bioaccumulate in marine life including various fish and shellfish species. The purpose of this study was to categorize participants into either the “fish” group (more fish than shellfish consumed) or the “same” group (either more shellfish than fish consumed or equal amounts of fish and shellfish consumed) via a seafood frequency questionnaire, and to administer a memory test to the participants to determine whether there is a significant difference in mean memory test scores between the groups. Methods: 31 participants were randomly selected at BCIT to participate in the study. Participation was voluntary and participants were given written and oral instructions on how to complete both the seafood frequency questionnaire and memory test. Memory test scores were based on the length of the longest digit sequence that the participant was able to recite upon hearing the examiner list the sequence. The highest possible score was a 10, while the lowest possible score was a 1. Results: The mean memory test scores of the groups, “fish” (more fish than shellfish consumed) and “same” (either more shellfish than fish consumed or equal amounts of fish and shellfish consumed), were 5.83 and 5.92, respectively. The median memory test scores of the groups, “fish” and ”same”, were both equal to 6. The standard deviations of the groups, “fish” and “same”, were 1.2004901 and 0.9540736, respectively. The ranges of the groups, “fish” and “same”, were 4 (minimum) to 8 (maximum) and 5 (minimum) to 8 (maximum). From the non-parametric Wilcoxon Rank sum test, the P-value was found to be >0.05 at α = 0.05. Conclusion: The results of this study suggest that diets relatively high in fish are neither positively nor negatively correlated with memory. However, the limitations of this study in combination with the various studies that contradict this study’s findings illustrate the need for further research.

Introduction The lack of awareness on the appropriate use of antibiotics, its dose and duration is one of the leading causes of global antimicrobial resistance (AMR). AMR poses a growing threat to public health, as infections from resistant strains of microbes become increasingly difficult to treat, resulting in prolonged illness and greater risk of death. Hence, this study would be an important reference for determining the scope of the problem which will be essential for formulating and monitoring an effective response to antibiotic use and its problem of resistance. MethodsA descriptive cross-sectional study was done among higher secondary level students from selected schools in Kathmandu valley. Baseline data was collected after a tutorial session through semi-structured questionnaires which was based on past researches and verified using expert consultation. Ethical consideration was maintained throughout the study. Descriptive statistics was used to find out the KAP level including knowledge score and attitude-practice score of the selected population. ResultsAmong 465 participants conducted in our research, the overall average knowledge score of the participants was found to be 73.3% while the attitude-practice score was 60.53%. It was found that 80.86% of the participants had heard the term “antibiotic resistance”. The knowledge score percentage among the students of grade 10 and 11 had no significant difference (p value= 0.592). ConclusionOur study concludes that if topics like antibiotics and their judicial use is well covered in school curriculum, it can produce measurable change in knowledge, attitude and practice level of the students.

Syntactic priming is a tendency for a speaker or writer to repeat of a recently produced or heard in a language structure by processing and sharing the same underlying syntactic structure which serves as the intervention for the students who were having difficulties in writing specifically on coordinating conjunctions.  It would enhance the secondary students’ writing proficiency in sentence construction to produce better-written outputs not only in educational context but also to the corporate world as well. This experimental research investigated the significant difference on the Grade 11 students Section Tulip before and after using syntactic priming as an intervention in writing. The researcher made use of structured test like pre-test and post-test to measure the effectiveness of syntactic priming in students’ writing performances. Statistical techniques such as mean and t-test were also used. Analyzed data revealed that there was an increased on their scored mean from pre-test to post-test among thirty identified participants as poor writers. Furthermore, there was a significant difference between pre-test and post-test since the P-Value (0.000) was lesser than 0.5, the null hypothesis was rejected with 95% level of confidence based on the students’ scores before and after taking the intervention which was not the same.

Synthesis of the 4-chlorobenzoylthiourea compound was carried out by acylating thiourea with 4-chlorobenzoyl chloride. The 4-chlorobenzoylthiourea compound  will increase the lipophilic and the electronic properties other than the lead compounds of benzoylthiourea in order to, by expectation, raise the central nervous system depressant as well. The lipophilic would affect the ability of the compounds in penetrating biological membranes, which is highly dependent on the solubility of the drug within lipid/water. Log P is the most common method used in determining the parameter value. This experiment was to mix two dissolvents (octanol and water) which are immissible. The both levels of the compounds were carefully observed by a spectrophotometer UV-Vis. From the test, the result of log P value of the 4-chlorobenzoylthiourea compound was 2.32, while the theoretical log P value of the compounds, by using the π Hansch-Fujita method is 1.62 and the f Rekker-Mannhold method is 2.225. Consequently, the result of the test shows that there is a significant difference between the progress experiment and both theoretical log P methods. Moreover, in the test of the central nervous system depressant through the potentiation test to thiopental using mice indicates that the 4-chlorobenzoylthiourea compound have potentiation effects to thiopental compared to the lead compounds of benzoylthiourea.

This study aims to investigate whether the use of six selected short stories throughout the duration of a 14-week course could enhance students’ reading comprehension achievement at the end of the semester. Out of the six short stories read, three were chosen as in-class assignments known as ‘Personal Reading Logs’ (hereafter, PRLs). One group of semester two Diploma students taking a reading skills course was selected through a convenience sampling method. A pre-test was conducted by having the students answer a past semester reading quiz of which the results would then be compared to their post-test (final reading exam) results. A paired samples t-test revealed no significant difference in the reading scores of the pre-test and the post-test, t (17) = -.265, p > .05. Since the p-value was bigger than 0.05, this indicated that the mean reading score of the post-test (M = 50.556) was not significantly higher than the mean reading score of the pre-test (M = 49.722). Therefore, the null hypothesis which stated that there was no difference in the mean score of the pre-test and post-test was retained. Overall, the result refuted the findings of other studies promoting the effectiveness of using short stories to enhance L2 reading comprehension achievement.

Abstract: Routine blood examination is the earliest blood test or screening test to determine the diagnosis of an abnormality. Blood easily froze if it is outside the body and can be prevented by the addition of anticoagulants, one of which Ethylene Diamine Tetra Acetate (EDTA). Currently available vacuum tubes containing EDTA anticoagulants in the form of K2EDTA and K3EDTA. K3EDTA is usually a salt that has better stability than other EDTA salts because it shows a pH approaching a blood pH of about 6.4. The purpose of this research is to know the difference of erythrocyte index results include MCH, MCV and MCHC using K3EDTA anticoagulant with K2EDTA. This research is a cross sectional design. This study used venous blood samples mixed with K2EDTA anticoagulant and venous blood mixed with K3EDTA anticoagulants, each of 30 samples. Data were collected and analyzed using paired different test. Based on data analysis that has been done on MCH examination, p value <0,05 then there is a significant difference between samples with K3EDTA anticoagulant with K2EDTA to erythrocyte index value. Then on the examination of MCV and MCHC obtained p value <0.05 then there is no significant difference between samples with K3EDTA anticoagulant with K2EDTA to erythrocyte index value.Abstrak: Pemeriksaan darah rutin merupakan pemeriksaan darah yang paling awal atau screening test untuk mengetahui diagnosis suatu kelainan.
