Cooking and Eating Quality Profiling of Some Popular Rice Cultivars In Bangladesh
Eating and cooking quality of rice plays major role in consumer’s preference for any cultivar. In the present investigation 21 popular rice cultivars were analyzed for their cooking and eating quality traits. Moderate variations were observed for all the traits studied except solid in cooking water. Among the cultivars, cooking time ranged from 14.02 to 21.37 minutes, water uptake ratio from 2.24 to 3.324 %, solid in cooking water from 1.027 to 1.049 gm, volume expansion ratio from 2.8 to 4.28 %, % amylose content from 17.367 (low) to 27.387(intermediate), protein content from 6.28 to 8.96 (%), and most of the cultivars were found with intermediate gelatinization temperature. Solid in cooking water was found positively correlated with cooking time, but negatively with water uptake ratio. Considering the preferences for cooked rice, high amylose content and low to intermediate gelatinization temperature of BRRI rice29, BRRI rice49 and Binarice-11 justified their popularity among the farmers and consumers
Bioactive Abietane-Type Diterpenoid Glycosides from Leaves of Clerodendrum infortunatum (Lamiaceae)
In this study, two previously undescribed diterpenoids, (5R,10S,16R)-11,16,19-trihydroxy-12-O-β-d-glucopyranosyl-(1→2)-β-d-glucopyranosyl-17(15→16),18(4→3)-diabeo-3,8,11,13-abietatetraene-7-one (1) and (5R,10S,16R)-11,16-dihydroxy-12-O-β-d-glucopyranosyl-(1→2)-β-d-glucopyranosyl-17(15→16),18(4→3)-diabeo-4-carboxy-3,8,11,13-abietatetraene-7-one (2), and one known compound, the C13-nor-isoprenoid glycoside byzantionoside B (3), were isolated from the leaves of Clerodendrum infortunatum L. (Lamiaceae). Structures were established based on spectroscopic and spectrometric data and by comparison with literature data. The three terpenoids, along with five phenylpropanoids: 6'-O-caffeoyl-12-glucopyranosyloxyjasmonic acid (4), jionoside C (5), jionoside D (6), brachynoside (7), and incanoside C (8), previously isolated from the same source, were tested for their in vitro antidiabetic (α-amylase and α-glucosidase), anticancer (Hs578T and MDA-MB-231), and anticholinesterase activities. In an in vitro test against carbohydrate digestion enzymes, compound 6 showed the most potent effect against mammalian α-amylase (IC50 3.4 ± 0.2 μM) compared to the reference standard acarbose (IC50 5.9 ± 0.1 μM). As yeast α-glucosidase inhibitors, compounds 1, 2, 5, and 6 displayed moderate inhibitory activities, ranging from 24.6 to 96.0 μM, compared to acarbose (IC50 665 ± 42 μM). All of the tested compounds demonstrated negligible anticholinesterase effects. In an anticancer test, compounds 3 and 5 exhibited moderate antiproliferative properties with IC50 of 94.7 ± 1.3 and 85.3 ± 2.4 μM, respectively, against Hs578T cell, while the rest of the compounds did not show significant activity (IC50 > 100 μM)
Genetic Modified Food for Ensuring Food Security Issues
Genetic modification is a technology that allows incorporating beneficial genes from other organisms. One of the major challenges of current era is feeding the consisting growing population of the world. Reduced cultivatable land and climate change have made it even more challenging. Through genetic engineering technology it is possible to develop high yielding, disease resistance and climate resilient crop varieties within shorter period of time than the conventional ways. Current global status of GM crop cultivation and production has already proved that GM crops have the potential to achieve food security for the future world. However, in most of the countries, public has misperception of its risks on human health and environment. Due to such misconception most of the countries have not adopted GM crops yet which could make it difficult to utilize GM crops to achieve food security. Therefore, in this book chapter we discussed on how genetically modified crops are developed, what beneficial traits are usually incorporated, how they are assessed for human health risks and regulations for selling genetically modified foods in the market. Such discussion would help common people to understand how this technology can help us ensuring food security of the world
Emblica officinalis improves glycemic status and oxidative stress in STZ induced type 2 diabetic model rats
ObjectiveTo evaluate the antidiabetic and antioxidant potential of Emblica officinalis (E. officinalis) fruit on normal and type 2 diabetic rats.MethodsType 2 diabetes was induced into the male Long-Evans rats. The rats were divided into nine groups including control groups receiving water, type 2 diabetic controls, type 2 diabetic rats treated with glibenclamide (T2GT) and type 2 diabetic rats treated with aqueous extract of fruit pulp of E. officinalis. They were fed orally for 8 weeks with a single feeding. Blood was collected by cutting the tail tip on 0 and 28 days and by decapitation on 56 day. Packed red blood cells and serum were used for evaluating different biochemical parameters.ResultsFour weeks administration of aqueous extract of E. officinalis improved oral glucose tolerance in type 2 rats and after 8 weeks it caused significant (P<0.007) reduction in fasting serum glucose level compared to 0 day. Triglycerides decreased by 14% but there was no significant change in serum ALT, creatinine, cholesterol and insulin level in any group. Furthermore, reduced erythrocyte malondialdehyde level showed no significant change (P<0.07) but reduced glutathione content was found to be increased significantly (P<0.05).ConclusionsThe aqueous extract of E. officinalis has a promising antidiabetic and antioxidant properties and may be considered for further clinical studies in drug development
Evaluation of out-patient care educational environment of National Defence University, Malaysia utilizing the ACLEEM Inventory
Purpose: A friendly educational environment is required for optimal learning, and students should be asked to provide feedback on their experiences to improve curriculum. Moreover, students’ academic progress, mental growth, and physical well-being are influenced by the educational and clinical environment of the institute. Essential constituents of the educational climate include atmosphere, number of proper teaching-learning sessions and available amenities. Primary health care and ambulatory settings allow students ample opportunities to interact with patients and observe health promotional activities more often practiced at the community levels. The study aims to evaluate the outpatient care educational environment of National Defense University of Malaysia by seeking feedback from medical students using Ambulatory Care Educational Environment Measure (ACLEEM) instrument.
Methods: This was a cross-sectional study. The study participants were medical students of the earlier mentioned university. The universal sampling method was adopted. The ACLEEM validated instrument was utilized for the data collection. The instrument was developed on the
basis of 5-point Likert Scale (Minimum: 0, and Maximum: 4).
Results: The response rate 100%. Most respondents were male, Malay and Muslim. The total mean score was 1.0±0.4. The domain mean scores for clinical teaching, clinical training, and support were 0.8±0.4, 1.1±0.4, and 1.1±0.5, respectively.
Conclusions: The ACLEEM questionnaire was found to be valid and reliable for local UPNM, Malaysian context. However, the overall ACLEEM scores reported for the present study is low, and some areas that could be improved. The UPNM authority should take appropriate measures to improve the educational environment to enhance the academic experiences of the medical students
Cardiovascular Disease and Diabetes: Two Sides of the Same Coin!
Cardiovascular disease (CVD) and type 2 diabetes (T2DM) are rapidly rising around the globe. Empirical researches demonstrated rapid increase in mortality and morbidity related to CVD and T2DM. Much of the diabetes-associated morbidity and mortality predominantly reflects its deleterious effect on macrovascular and microvascular diseases. The microvascular complications of T2DM include retinopathy, neuropathy and nephropathy and the macrovascular complications include ischemic heart disease, cerebrovascular disease and peripheral vascular diseases. Research indicates that coronary heart disease (CHD) is the major cause of mortality in people with T2DM. Herein, this chapter reviews relationship between CVD and T2DM, associated complications and effectiveness of relevant treatment modalities to treat/prevent diabetic macrovasculopthy. Macrovascular disease occur due to underlying obstructive atherosclerotic changes of major arteries which cause functional and structural abnormalities of blood vessels. The long-term complications can be controlled and prevented by controlling glycemia, maintaining normal lipid profiles, adopting a healthy lifestyle and using pharmacological interventions. Clinical trials have shown that lifestyle interventions help in prevention and reduction of CVD risk, but evidence for long-term CVD outcomes is lacking. A multidisciplinary approach involving patients, health professionals and researchers and governments should be undertaken to reduce the incidence and prevalence of diabetes-related cardiovascular complications

Perception of tomorrow’s Health-Care connoisseur and front-runners of their educational environment utilizing DREEM inventory in Bahasa Melayu version, the native language of Malaysia
Background
There have been a lot of reports throughout the world that medical students were abused during their undergraduate education and clerkship training. Thereafter, calls for intensifying the evaluation of medical and health schools’ curricula based on students’ perceptions of their educational environment. Several studies, methods, and instruments were developed including the Dundee Ready
Education Environment Measure (DREEM) inventory, to evaluate the medical educational environment in last five decades. The DREEM inventory has been translated into minimum eight different native tongues namely Arabic, Chinese, Japanese, Persian, Portuguese, Spanish, Swedish, and Turkish.
Aims
The objective of this study was to assess the educational environment of the UniSZA undergraduate medical program from the students’ perspective utilizing the DREEM inventory translated in Bahasa Melayu.
Methods
This was a descriptive cross-sectional survey conducted among the medical students of session 2015-2016 to assess educational environment of the Faculty of Medicine, UniSZA. The study was conducted from December 2015 to January 2016. Universal sampling technique was adopted.
Results
A total of 277 (95.5 per cent) out of 290 students responded to the questionnaire; among them 27.4 per cent were male and 72.6 per cent were female respondents. The overall mean DREEM scores for both preclinical and clinical students were 67.41±24.06. The scores for pre-clinical and clinical were 64.02±25.10 and 69.65±23.15 respectively; however, no statistically significant (p=0.57) differences was observed between two phases. A significant difference was observed between gender of the respondents in students’ perceptions of teachers (p=0.005) and students’ social self-perceptions (p=0.046)
Perceptions of medical students regarding community-based teaching experiences: an observation from Bangladesh
Introduction: Community orientation in medical education, which prepares medical students to become more effective practitioners, is now a global movement. Many medical schools around the world have adopted the concept as the main curricular framework in order to align learning programs with the needs of the community and the learner. Despite many changes over the past few decades, many improvements are still needed in medical education in Bangladesh. This study investigated medical students’ perceptions of the community-based learning experiences incorporated into the Bachelor of Medicine, Bachelor of Surgery (MBBS) degree at Uttara Adhunik Medical College, Dhaka (UAMC), Bangladesh.
Methods: A total of 135 students from three undergraduate year levels of the MBBS degree at UAMC, Dhaka, Bangladesh, undertook study tours (community-based teaching, CBT) as a part of a community medicine course and visited a medical college, two rural health centres and a meteorology centre in the Cox’s Bazar district, 400 km from Dhaka city. A questionnaire was used to assess the perceptions of students regarding the administration, organisation and learning experiences of the study tours. Students were required to write reports, present their findings and answer questions in their examinations related to the study tours and CBT.
Results: The majority of the students agreed or strongly agreed that the tour was a worthwhile (93%) and enjoyable (95%) learning experience that helped them to understand rural health issues (91%). More than half of the students reported that the study tours increased their awareness about common rural health problems (54%) and provided a wider exposure to medicine (61%). Only 41% of students reported that the study tour increased their interest in undertake training in a rural area. A substantial number of students also expressed their concerns about the planning, length, resources, finance and organisation of the study tours.
Conclusions: Overall, the study tours had a positive effect, enhancing students’ awareness and understanding of common rural health problems. As study tours failed to increase the motivation of the students (approximately 60%) to work in rural areas, CBT in the medical curriculum should be reviewed and implemented using effective and evidence-based models to promote interest among medical students to work in rural and underserved or unserved areas
Self-medication of antibiotics: investigating practice among university students at the Malaysian National Defence University
Background: Self-medication of drugs to alleviate symptoms is a common global behavior, helping relieve burdens on health services, but many drugs eg, antibiotics are prescription-only. Self-medication of antibiotics (SMA) is an irrational use of drugs, contributing to microbial resistance increasing health care costs and higher mortality and morbidity. This study aimed to assess SMA among university students. Methods: This was a cross-sectional study conducted among medical and non-medical students of the National Defence University of Malaysia. A validated instrument was used to gather data. Ethics approval was obtained. Random and universal sampling was adopted, and SPSS 21 was used for data analysis. Results: A total of 649 students participated in the study: 48.5% male and 51.5% female, 39.3% reported self-medicating with antibiotics. Penicillin, doxycycline, clarithromycin were the antibiotics most used with the majority reporting no adverse drug reactions. Cost savings and convenience were the principal reasons for SMA which were mainly obtained from local retail pharmacies. Despite medical students (particularly the more senior) having better knowledge of antibiotic use than non-medical students, 89% of all research participants responded that practicing SMA was a good/acceptable practice. Conclusion: SMA is common amongst Malaysian students and, despite understanding why SMA is unwise, even medical students self-medicate
