AIM OF THE STUDY: This study aimed to compare the differential toxicity and teratogenicity (if any) of the hot water (HW) and cold water (CW) extracts of both wild and cultivated sclerotium on zebrafish (Danio rerio) embryos.
MATERIALS AND METHODS: Zebrafish embryos were treated with varying concentrations of the sclerotial HW and CW extracts (0.3-500 μg/mL) for 72 h until hatching. The hatching, mortality and heartbeat rate of the embryos as well as the potential teratogenic effect of the extracts were assessed in embryos post-treatment with the extracts.
RESULTS: While the sclerotial HW extracts were nontoxic (LC50 > 500 μg/mL), the sclerotial CW extracts delayed the hatching of the embryos up to 48 h and showed slight toxicity with LC50 values of 398.4 μg/mL and 428.3 μg/mL for the cultivated and wild sclerotium, respectively. The sclerotial CW extracts also induced minor tachycardia in zebrafish larvae. Phenotypic assessment revealed that, while yolk sac edema was observed at high concentrations (300 and 500 μg/mL) of all extracts, curved trunk and bent tail were only observed in the embryos treated with CW extracts of wild sclerotium (300 and 500 μg/mL) but not for CW extracts of cultivated sclerotium at similar concentrations.
CONCLUSION: The sclerotial water extracts of L.rhinocerus prepared using different methods have varying degree of toxicity and teratogenicity in zebrafish embryos with the sclerotial CW extracts showed higher toxicity than the HW extracts.
METHODS: A case control study was conducted among 142 newly diagnosed IHD women patients registered in government hospitals in Terengganu, Malaysia and their 1:1 frequency matched population controls. Data on sociodemographic and socioeconomic profile, co-morbidities, lifestyle factors related to physical activities, dietary fat intake, stress, passive smoking history, anthropometric measurements and biochemical markers were obtained.
RESULTS: Middle aged women were recruited with women diagnosed with diabetes (aOR = 1.92, 95% CI: 1.11-3.31), having low HDL-C (aOR = 3.30, 95% CI: 1.28-8.27), those with positive family history of IHD (aOR = 1.92, 95% CI:1.13-3.26) and passive smokers (aOR = 2.99, 95% CI:1.81-4.94) were at higher odds of IHD.
CONCLUSIONS: The findings are useful for public health interventions and policy making focusing on specific women population.
METHOD: A cohort study was conducted where 33 severe TBI survivors recruited at two tertiary hospitals. The health-related quality of life was measured using the Quality of Life after Brain Injury (QOLIBRI) tool.
RESULTS: Participants mean age was 31.79 years old. The impaired range of health-related quality of life on 6 months post-injury seen, but an improvement occurs within 3-6 months post-injury.
CONCLUSIONS: Age and ventilation duration showed a moderate negative correlation in all domains and length of hospital stay showed a moderate negative correlation to social, daily life and self-domains. Nevertheless, small sample size and time constraint were the limitations of this study.
