Readiness of PSMZA Lecturer on The Use of Mooc Platform in Learning and Teaching

Currently, Malaysia is faced with challenges in efforts to provide a quality educational system. One of the surge in the Development Plan of Education (higher education) 2015-2025 is to ensure learning online at global level. So with this, the use of platform MOOC is one the first method was introduced as one of the approaches in learning and teaching. However the question arises whether polytechnic lecturer was ready to use online learning extensively, particularly in the process of learning and teaching. This study is intended to review the availability of committed lecturers Politeknik Sultan Mizan Zainal Abidin of the use of platform MOOC in learning and teaching. Respondents were 153 lecturers in PSMZA and it has been selected at random. The instruments used are a set of survey questions. The findings indicate the availability of lecturers PSMZA will against the use of platform MOOC in learning and teaching are not influenced by gender. The mean score for female lecturers was 2.83 compared mean score men namely 2.57 and this shows women more ready against the use of platform MOOC. The mean score for aspects of female lecturers obstacles higher than male lecturers. This suggests that female lecturers more willing to use MOOC in learning and teaching although there are some aspects which have become obstacles. Someone who had the expectation of high availability using MOOC are less face obstacles while using MOOC in learning and teaching sessions. Coefficient of correlation variables obstacles in the use of MOOC and graduate readiness against MOOC is very weak with the value of the coefficient of correlation of -0.078. It is mean that female lecturers more willing to use MOOC in learning and teaching although there are some aspects which have become obstacles. Therefore clearly showed the use of MOOC among the lecturers PSMZA will provide positive indicators and should be polished to ensure the integration of technology in education achieved towards helping towards the Industrial Revolution 4.0

Total Phenolic, Total Flavonoids Content and Antioxidant Activity of Mangifera sp. Leaf Extracts

Mangifera sp. is a versatile plant that was reported to have various bioactivities, however only the fruits have gain popularity due to it sweet flesh and been known worldwide. It has a potential source of flavonoids and carotenoids, which makes them a nutritious functional food to consume.  This study focused on determination of the total phenolic content (TPC), total flavonoid content (TFC) and antioxidant activity of the Mangifera sp. leaves extract in different water extraction methods. The TPC and TFC was determined by using Folin-Ciocalteu method and aluminium chloride method respectively while antioxidant activity was determined using 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay and ferric reducing antioxidant power (FRAP) assay. Soxhlet extraction (SXE) produced the highest extraction yield compared to microwave extraction (MWE).  MWE at 8 minutes extract showed the highest TPC (262.13±0.05 mg GAE/g). SXE showed the highest TFC (413.46±0.77 mg rutin/g). The highest antioxidant activity was recorded in MWE 8 minutes extract through DPPH and FRAP assays compared to other two MWE extract and SXE extract

Effect of pH on Different Strains of Phytase Producing Bacteria from Malaysia’s Hot Spring

In the recent research, the optimisation of culture condition for phytase production rarely done for Acetinobacter baumanii. The optimisation of the phytase production from the bacterial strains largely contributed by Bacillus sp. The study on the phytase originated from hot spring are limited and the species that identified from the hot spring samples are not in the same species from the previous study and mainly the species isolated from Bacillus sp. In this study, four potential strains of bacteria producing phytase isolated from hot spring in several regions in Malaysia. For enrichment of the bacterial, Nutrient Agar was used, meanwhile for batch culture optimisation, the bacteria producing phytase grown in modified liquid Phytase Screening Media with soy extract as agro residual substrate as a replacement for sodium phytate, the chemical substrate. The bacteria were screened for their ability to produce clear zone in solid PSM with sodium phytate as substrate. Optimisation of media through its physical factor that is pH of the media carried out using shake flask scale in laboratory. The growth of the bacterial strains and phytase activity measured quantitatively through the two different pH of media at pH 5.5 and pH 7. The analysis of colony-forming unit and pH determination after fermentation was carried out in this study. From the study, bacterial strain L3 from Labis, Johor has the highest phytase activity in the two parameters studied where the inorganic phosphate released at pH 5.5 (0.21953 U/mL) and pH 7 (0.2047 U/mL). Optimisation carried out through manipulating the culture condition that is pH of the media to determine at which condition has the highest phytase production. Several effects on enzyme activity caused by culture conditions identified. The optimisation of the fermentation medium able to contribute to the less cost production of the industrial enzyme as phytase has potential production for feed additives for poultry feeding. In the future research, molecular identification of the bacterial strains from the better-quality bacteria producing phytase grown in optimised culture media to investigate the molecular identity of the bacterial

Comparison on Effects of Temperature on Different Strains of Phytase Producing Bacteria Isolated from Malaysia’s Hot Spring

The main purpose of this research was to find the best growth curve for bacterial growth and the optimum temperature for the production of phytase from different potential phytase producing bacterial strains. A total of four strains used were originally isolated from hot springs in Malaysia, which were in Labis, Johor (L3), Dusun Tua, Selangor (RT), Ulu Legong, Kedah (A) and Ranau, Sabah (B9). Nutrient Agar (NA) and modified Phytase Screening Medium (PSM) liquid media were used for the culture enrichment while optimisation was carried out through batch culture method using a shake-flask scale. Strains growth and enzyme activity were quantitatively measured at different temperatures at (30°C and 37°C) values. Enzyme activity was determined according to the reaction of the phytase with its substrate (sodium phytate) and expressed in units of phytase activity (U/ mL). As for the overall, strain L3 (from Labis, Johor) exhibit promising rate of Pi released in the media at 30°C and 37°C, with optimum phytase activity values of 0.2047 U/mL and 0.2195 U/mL, respectively. The pH of the cultures was also measured, where it shows that strains grown in cultures at 37°C produced a higher phytase activity and resulting a lower reading of pH compared when grown at 30°C. All around, L3 strains has the lowest value of pH when cultured at 30°C and 37°C, with the pH value of 3.62 and 2.37, respectively.  From the result obtained, the lower pH indicates the process of phytic acid degradation take place by the phytase in producing inorganic phosphate (Pi) due to the accumulation of organic acid. Since these bacterial strains were originally taken from Hot Springs, further analysis of temperature optimization using 55°C and even 60°C should be carried out. In the future, biochemical research and molecular identification may also be carried out to identify molecular identity in the strains

Micronuclei Formation and 8-Hydroxy-2-Deoxyguanosine Enzyme Detection in Ovarian Tissues After Radiofrequency Exposure at 1800 MHz in Adult Sprague–Dawley Rats

Human fertility and its correlation to ovarian function and cytological changes are linked to ever-increasing use of mobile phones. Wireless communications have become a critical topic of concern because of an increasing number of studies in this field with controversial outcomes. The aim of this study was to assess the genotoxic effect of GSM frequency at 1800 MHz on ovarian function. Sixty female Sprague–Dawley rats were distributed over six groups (control group and the exposure groups with whole-body exposure for 2 h/day, 7 days/week for 15, 30 and 60 continuous days). The study investigated the oxidative stress, 8-hydroxy-2-deoxyguanosine enzyme, micronuclei formation and histopathological changes in ovarian tissue. The results showed an induced oxidative stress via an increase in lipid peroxidation and decreased antioxidant enzyme activity. There was also an elevation in the 8-hydroxy-2-deoxyguanosine enzyme and an increased rate of micronuclei formation in ovarian tissues of exposed animals with 60-day exposure compared with control animals. Cytological changes were recorded such as micronuclei formation, vacuolation, degeneration and impaired folliculogenesis. The study suggests that GSM frequency at 1800 MHz was negatively impacted on female reproductive performances mediated by oxidative stress induction and 8-hydroxy-2-deoxyguanosine formation leading to overall impaired ovarian function

Evaluation of ampicillin, vancomycin, and gentamycin antibiotic resistant among lactobacillus isolates / Rozila Alias... [et al.]

Antibiotic resistance is an ever-increasing in worldwide problem nowadays. It is happened when the exten- sive use of antibiotics which will creates the selective pressure resulting from mutation of normal genes and spreading of a variety of an antimicrobial resistance. Uses of Lactobacillus as probiotics or in starter cultures may serve as hosts of antibiotic resistance genes, which could be transfer or resistance to multiple antibiotics. Therefore, it is important to screen the susceptible or resistance towards antibiotics which will not transferable resistance genes. In the recent study, a total of 37 strains of Lactobacillus species isolated from various milk and dairy products such as goat’s milk, cattle’s milk, human’s milk, homemade yogurt and commercial yogurt were examined for the antibiotic profile using Kirby-Bauer method. The results of this study show that human’s milk has a high number of Lactobacillus isolates resistant to ampicillin (75%), vancomycin (62.5%) and gentamycin (62.5%). Whereas Lactobacillus isolated from cattle’s milk have resistant to ampicillin (42.1%), vancomycin (42.1%) and susceptible to gentamycin (0%). But however, goat’s milk still has lower percentage number of resistant to ampicillin (28.0%), vancomycin (14.3%) and are susceptible to gentamycin (0%). These results indicate that ampicillin and vancomycin resistant seems to be very common among Lactobacillus isolates but gentamycin are still susceptible used. Vancomycin resistant are more concerned because of the emerging problem in hospital and often described as one of the last resorts against the infection caused by multidrug-resistant pathogens. Therefore, lactobacilli as probiot- ics would be more monitoring when applied in food industry and clinical especially for immune compromised patients or during anti-biotherapy. Acquisition and retransfer of resistance genes should be addressed in the new safety aspects of probiotics uses.addressed in the new safety aspects of probiotics uses
