Acute modulatory effects of apple cider vinegar, garlic, ginger, lemon and honey mixture, with and without exercise on postprandial glycemia innon-diabetic females

Postprandial hyperglycemia is independently related to cardiovascular disease. Garlic, ginger, lemon, honey and apple cider vinegar are known to have anti-glycemic properties. However, the effectiveness of combination of these natural products on reducing postprandial glycemia is uncertain. The aim of the present study was to investigate the glucose-lowering effect of a novel mixture consisting of apple cider vinegar, garlic, ginger, lemon, and honey; alone and in combination with exercise in response to a high-carbohydrate meal in non-diabetic individuals. Ten, female subjects (mean age: 25 ± 2.67 years, mean BMI: 22.6 ± 3.5 kg/m2) participated in this randomised, cross-over intervention consisting of four trials: control (CON), mixture only (MIX), exercise only (EX), and exercise + mixture (EX-MIX). All trials involved consumption of a high-carbohydrate breakfast, then followed by rest in CON, consumption of natural product mixture in MIX, brisk-walking exercise in EX, and combination of mixture and exercise in EX-MIX. Blood glucose was measured at fasting, and at 30, 60, 90, 120 minutes post meal. Postprandial glucose response was calculated as area under the glucose curve. Two-way repeated measures ANOVA showed a significant group and time interaction (p < 0.001). Compared to CON, postprandial glucose responses were 8%, 13% and 15% lower in MIX (p = 0.049), EX (p = 0.001) and EX-MIX (p = 0.005) respectively. Postprandial glucose was 8% lower in EX-MIX compared to MIX (p = 0.002). In conclusion, consuming natural product mixture containing garlic, ginger, lemon, honey and apple cider vinegar reduced postprandial glycemia to a certain extent, however, combining mixture with exercise produced a greater attenuation effect compared to consuming mixture alone. This finding is indicative of a potential benefit of the novel mixture as a complementary management of hyperglycemia in high-risk individual

Zingiber zerumbet (L.) Smith hexane crude extract caused DNA damage on Leptospira spp.

Numerous attempts have been made to control leptospirosis by using chemoprophylaxis, but with limited success. The present study was done to investigate the antileptospiral potential of hexane, ethyl acetate and methanol extracts of Zingiber zerumbet rhizomes. The extracts were assayed for antileptospiral activity using broth microdilution method against Leptospira interrogans (serovar Batavie, Canicola, Australis) and Leptospira biflexa serovar Patoc. The Z. zerumbet hexane extract exhibited antileptospiral activity, with IC50 values of 248 μg/mL against L. interrogans serovar Canicola, IC50 of 125 μg/mL against L. interrogans serovar Australis, IC50 of 15.63 μg/mL against L. interrogans serovar Batavie and IC50 of 109 μg/mL against L. biflexa serovar Patoc. However, both ethyl acetate and methanol extracts did not show any distinct antileptospiral activity. Since the hexane extract of Z. zerumbet showed antileptospiral activity, the DNA-damaging properties of this extract were tested according to their IC50 and IC25 values that were specific to each serovars. The DNA-damaging properties were determined by treating the selected Leptospira spp. with the hexane extract and subjecting its DNA to electrophoresis and analysis on agarose gels. The results demonstrated that the hexane extract had DNA-damaging properties towards L. biflexa serovar Patoc and L. interrogans serovar Australis, as proven by the appearance of fragmented DNA on the gels. We conclude that the Z. zerumbet hexane extract could inhibit the growth of Leptospira spp. serovar Patoc and Australis through DNA-damaging activity and thus, could be a potential antileptospiral agent. Further studies are needed to investigate the potential of this hexane extract as an antileptospiral agent using in vivo rat models of leptospirosis

Neuroprotective effects of ethyl acetate extract of Zingiber zerumbet (L.) Smith against oxidative stress on paraquat-induced parkinsonism in rats

Zingiber zerumbet has been traditionally used as an anti-inflammation and antioxidant agent. The present study investigates the neuroprotective effects of ethyl acetate extract of Z. zerumbet against oxidative stress on paraquat (PQ)-induced Parkinsonism in rats. Forty male Sprague-Dawley rats were divided into five groups: Negative control (normal saline), positive control (N-acetylcysteine, NAC 20 mg/kg + PQ 10 mg/kg), PQ only, 200 mg/kg Z. zerumbet + PQ and 400 mg/kg Z. zerumbet + PQ. The extract was given orally for 19 consecutive days and PQ was administered intraperitoneally on day 8-12th of the treatment regime. Both serum and fresh brains containing substantia nigra (SN) region were taken for biochemical and histological analysis. Administration of both 200 and 400 mg/kg ethyl acetate Z. zerumbet extracts to the PQ-treated groups have resulted in: Decreased levels of MDA and PC in the SN homogenates; and increased SOD, GPx; and CAT activities in the SN and serum. Overall, ethyl acetate extract of Z. zerumbet reduced oxidative stress in the SN of PQ-induced neuronal damages, therefore, has the potential to be developed as a preventive agent for neurodegenerative disorders caused by environmental toxins

Mechanism identification of Ficus Deltoidea aqueous extract in rat uterine contractions

Ficus deltoidea or ‘mas cotek,’ is a uterotonic herb traditionally consumed by women to improve menstrual circulation, assist labour, remove retained placenta and treat postpartum bleeding. The aim of the study was to elucidate the mechanism of F. deltoidea in uterine contraction. Crude extracts from 2 different variants of F. deltoidea were used in the study; F. deltoidea var. Deltoidea (FDD) and F. deltoidea var. Angustifolia (FDA). This study was conducted ex vivo on the strips of isolated rats uterus treated with either FDD or FDA aqueous extract with increasing concentrations ranging from 10 μg/ml until 1280 μg/ml at time intervals of 5 minutes between doses. The frequency and intensity of the uterine contractions were monitored via Powerlab software. Maximum contractions for both extracts were identified, recorded and the uterine strips samples at maximum contraction were selected and homogenized in order determine the role of prostaglandin F2α (PGF2α) in the mechanism of uterine contraction. Other than that, phosphorylated 42/44 (p42/44) of mitogen activated protein kinase (MAPK) expression was also detected via immunoblotting. The results showed that the maximum contraction induced by FDD was at the concentration of 320 μg/ml, whereas for FDA was at 960 μg/ml. Both FDD and FDA increased the intensity of uterine strips contractions and there were notable trend of increased PGF2α expression as well. Further analysis revealed that the uterine contractions involved the MAPK pathway through the phosphorylation of p42/44 protein. In conclusion, Ficus deltoidea of both variants have the ability to stimulate uterine contraction through the mechanism of MAPK pathway

Digital caricature drawing enhances students’ understanding in learning about chromosome

Humans have 24 different types of chromosomes and each chromosome can be identified by its unique characteristics. In a cytogenetics laboratory, analyzing chromosomal characteristics is crucial because it is performed on real patient samples, allowing diseases to be diagnosed directly. However, identification of these chromosomes is difficult to perform for novices in this field, particularly biomedical science students. Drawing is one of the teaching and learning tools that has been shown to improve memory, information processing, cognitive process, and comprehension. The drawing approach is incorporated into the Cytogenetics subject due to these advantages. The students were given an Easy ID Chromosome Caricature e-Book, which contains a collection of human chromosomes with unique characteristics being highlighted and they must use a graphical software to transform the chromosomes into caricatures. Their feedback was gathered before and after the intervention was carried out. There were noticeable improvements in the students’ understanding of the chromosomes’ characteristics, ability to identify and differentiate the chromosomes based on their respective numbers and acquisition of relevant soft skills. Chromosome caricatures require high imagination and drawing skills, which could be used as alternative teaching and learning tools in Cytogenetics. The favorable feedback received encourages the strategy to be implemented in the subsequent cohorts of students

The effects of genetic inheritance E-game to undergraduate students

The COVID-19 outbreak that is occurring worldwide has affected the education system, as the closure of education institutions has halted teaching and learning activities. Nevertheless, online education is being widely applied to complete the curriculum. As learning activities are limited by the prohibition of face-to-face classes, an E-game on genetic disease inheritance was designed and introduced to undergraduate Biomedical Science students of Universiti Kebangsaan Malaysia (UKM). In this approach, the students were divided into small groups of 5-7 students and they were required to grasp the basic knowledge of genetic disease inheritance including drawing a pedigree tree in order to understand genetic-based diseases, develop three case studies, four case studies-related questions and also provide the answer scheme beforehand. During the E-game, the Microsoft Teams online learning platform was used. Each of the groups took turns to present case studies on the topic of genetic disease inheritance and answered questions. Marks were given for each of the answers. The students’ feedback was collected to evaluate the outcome of this approach. Their understanding on pedigree drawing topics, ability to draw pedigree diagram and analysing genetic inheritance case studies were significantly (p<0.001) increased after the e-game implementation. In addition, the e-game helped them to develop several skills such as teamwork and strategizing. Overall, the students were benefited with the approach, even though some limitations in internet accessibility and devices problems were encountered during the e-game. As conclusion, the e-game was successfully tailored to deliver the genetic inheritance topic previously outlined for face to face session

Effects of aerobic exercise and dietary flavonoids on cognition: a systematic review and meta-analysis

Introduction: Studies have shown that exercise increases angiogenesis and perfusion in the hippocampus, activates neurogenesis in the dentate gyrus and increases synaptic plasticity, as well as increases the complexity and number of dendritic spines, all of which promote memory function and protect against cognitive decline. Flavonoids are gaining attention as antioxidants in health promotion due to their rich phenolic content, particularly for their modulating role in the treatment of neurodegenerative diseases. Despite this, there has been no comprehensive review of cognitive improvement supplemented with flavonoid and prescribed with exercise or a combination of the two interventions has been conducted. The purpose of this review is to determine whether a combined intervention produces better results when given together than when given separately.Methods: Relevant articles assessing the effect of physical exercise, flavonoid or in combination on cognitive related biomarkers and neurobehavioral assessments within the timeline of January 2011 until June 2023 were searched using three databases; PubMed, PROQUEST and SCOPUS.Results: A total of 705 articles were retrieved and screened, resulting in 108 studies which are in line with the objective of the current study were included in the analysis.Discussion: The selected studies have shown significant desired effect on the chosen biomarkers and neurobehavioral assessments.Systematic Review Registration: identifier: [CRD42021271001]

Hubungan antara hafazan al-Quran dan kualiti hidup pelajar tahfiz di Selangor, Malaysia

Kajian terdahulu menunjukkan kualiti hidup dapat ditingkatkan melalui amalan keagamaan dan kerohanian. Hafazan al-Quran merupakan amalan keagamaan dan kerohanian yang memperkasa aspek mental dan fizikal. Namun, kajian saintifik yang mengaitkan hafazan al-Quran dengan kualiti hidup masih terhad terutamanya dalam konteks pelajar tahfiz. Maka, kajian ini bertujuan untuk mengenal pasti hubungan antara hafazan al-Quran dengan kualiti hidup dalam kalangan pelajar tahfiz di Selangor, Malaysia. Satu kajian keratan rentas telah dijalankan ke atas 116 pelajar dengan pensampelan rawak berstrata dari tiga buah sekolah tahfiz di Selangor. Pelajar tahfiz dikategorikan kepada tiga tahap hafazan berdasarkan jumlah juzuk yang telah dihafaz iaitu Tahap 1 (1-10 juzuk), Tahap 2 (11-20 juzuk) dan Tahap 3 (21-30 juzuk). Borang soal selidik telah digunakan untuk mendapatkan data sosiodemografi dan borang soal selidik Short Form-36 Quality of Life (SF-36) versi Bahasa Malaysia telah digunakan untuk menilai tahap kualiti hidup. Data telah dianalisa menggunakan SPSS versi 23.0. Hasil kajian mendapati wujud hubungan positif yang signifikan antara hafazan al-Quran dengan kesihatan fizikal (r = 0.300, p < 0.05) dan kesihatan mental (r = 0.194, p < 0.05). Ini jelas menunjukkan bahawa semakin banyak pelajar menghafaz al-Quran semakin tinggi tahap kualiti hidup mereka. Faktor yang mempengaruhi kesihatan mental dan fizikal adalah jumlah muka surat hafazan. Kesimpulannya, hafazan al-Quran berpotensi meningkatkan kualiti hidup serta kesihatan mental dan fizikal pelajar tahfiz

Dietary intake, levels of trace elements and intelligence quotient (IQ) among huffaz students from selected tahfiz schools in Selangor

Tahfiz education has been well accepted by Muslims in Malaysia. Memorizing the Quran through rote learning can assist in improving the brain ability to process, store information and build memory. In addition, dietary intakes were reported to contribute in the process of memorizing the Quran and to increase the levels of intelligence (IQ) among huffaz students. This cross-sectional study was conducted to measure and to determine the correlation between IQ and dietary intake as well as between IQ and the level of trace elements among students in selected tahfiz schools and non-tahfiz school in Selangor. Questionnaires were used to obtain demographic data. Dietary intake was assessed via 3 days dietary record. Levels of trace elements in the nail samples were analyzed by using ICP-MS. Test for intelligence using WASI-II was conducted to measure the students’ IQ. The results showed that there was a moderate positive correlation between IQ and carbohydrate (r = 0.425, p < 0.001, a weak positive correlation between IQ and energy (r = 0.260, p < 0.05), vitamin B6 (r = 0.189, p < 0.05), vitamin B12 (r = 0.207, p < 0.05) and vitamin C (r = 0.211, p < 0.05). The levels of trace elements in nail samples showed no correlation with IQ, whereas there were moderate positive correlations between IQ and dietary zinc (r = 0.375, p < 0.001) as well as between IQ and dietary iron (r = 0.303, p < 0.001). There was also a moderate positive correlation between IQ and the level of memorization (r = 0.375, p < 0.001). The results of stepwise multiple linear regression showed that al-Quran memorization influence the level of IQ by 20 %. As a conclusion, dietary intake of certain nutrients including energy, vitamins and selected trace elements can potentially improve memorization activities and also IQ
