Terbuthylazine (TBA) is a common triazine herbicide used in agricultural production, which causes toxic damage in multiple tissues. Hesperidin (HSP) is a flavonoid derivative that has anti-inflammatory, antioxidant and cytoprotective effects, but its role in reducing toxic damage caused by pesticides is still unclear. In this study, we aimed to investigate the toxic effect of TBA exposure on chicken hepatocytes and the therapeutic effect of HSP on the TBA-induced hepatotoxicity.

Exposure to copper (Cu) has been associated with metabolic disorders in animals and humans, but the underlying mechanism remains unclear. One-day-old broiler chickens, numbering a total of 192, were nourished with dietary intakes that contained varying concentrations of Cu, specifically 11, 110, 220, and 330 mg/kg of Cu, for a period extending over a duration of 7 wk. As a result of the study, Cu exposure resulted in vacuolization, fragmentation of mitochondria cristae, and the increase of autophagosomes in hepatocytes.

Background Infants who are born between 34 0/7 and 36 6/7 weeks of pregnancy as a result of maternal or fetal factors are defined as "late preterm infants". Compared to term infants, late preterm infants are more predisposed to pregnancy complications because they are less mature physiologically and metabolically. In addition, health practitioners still face difficulties in differentiating between term and late preterm infants due to similar general appearance.

This paper aims to review the literature on 'Effective Microorganism (EM)' and 'Fertilizer' from the Scopus database and to discuss EMs using -based sources for biofertilizer production from socio economic insights. Based on EM and fertilizer publications on the Scopus database, all the 17 papers reviewed provided no detailed information on the -status of the biofertilizers inoculated with EM. The impacts of -certified biofertilizers will trigger the certification in food products by (a) catering for the increasing food demand due to expectedly Muslim population expansion, (b) contributing to the sustainable buying behaviour of products' consumers in the future, (c) catering for the increasing number of Muslim travellers around the world, (d) becoming a positive driver for higher production of more foods that can enhance food safety, human health and well-being, and (e) creating a cost-effective and increasing food marketability.

The present study aimed to confirm the use of the byssus (BYS) of the green-lipped mussel as a biomonitoring biopolymer for zinc (Zn) by comparing it to copper (Cu) and cadmium (Cd) pollution in coastal waters under experimental field conditions, based on the transplantation of caged mussels between polluted and unpolluted sites in the Straits of Johore (SOJ). Four important evidential points were found in the present study. First, the 34 field-collected populations with BYS/total soft tissue (TST) ratios > 1 indicated that the BYS was a more sensitive, concentrative, and accumulative biopolymer for the three metals than TST.

Background: Coronary artery disease (CAD), manifested mainly as acute coronary syndrome (ACS), continues to be a major cause of mortality globally and a significant contributing factor to the global disease burden. Elevation of low-density lipoprotein cholesterol levels attributed to proprotein convertase subtilisin/Kexin type-9 (PCSK9) during and following ACS puts patients at high risk of subsequent adverse events. Evolocumab is a PCSK9 inhibitor that is associated with a significant reduction in low-density lipoprotein cholesterol (LDL-C) levels through PCSK9 inhibition in comparison to traditional statin therapy.

Article Synopsis
  • This study investigated the levels of potentially toxic metals (Cu, Ni, Pb, Zn) in surface sediments of the Klang mangrove ecosystem and examined the ability of Avicennia officinalis to help clean up these metals through phytoremediation.
  • The concentrations of the metals varied, with Cu posing a moderate ecological risk while Ni, Pb, and Zn were deemed to have low potential ecological risks; all the metals were found to be non-carcinogenic according to the hazard index.
  • The research identified specific parts of the Avicennia officinalis plant that are more effective in removing essential and non-essential metals, providing valuable data to manage and protect the ecological health of the Klang mangrove ecosystem.

Background Hemorrhage after trauma is the second leading cause of death in patients in the prehospital environment, and intervention by bystanders before the arrival of professional rescuers has the potential to save lives in such circumstances. No studies have been conducted in Saudi Arabia till date to assess the knowledge and awareness of bleeding control by bystanders. Hence, this study was conducted with an aim to assess the level of awareness, attitude, and willingness toward bleeding control by bystanders in Riyadh city, the capital of Kingdom of Saudi Arabia (KSA).

Article Synopsis
  • - This study evaluated the health risks of nickel (Ni) exposure from consuming certain marine fish and mollusks in Setiu, Terengganu, Malaysia, focusing on 19 fish species and two types of seafood: mangrove snails and cockles.
  • - Nickel levels in these seafood types were found to be below the maximum permissible limit, and the risk evaluations indicated that Ni's target hazard quotient values were less than 1.00 for Malaysian consumers, suggesting no significant non-carcinogenic risk from seafood consumption.
  • - The estimated weekly intake of nickel from these seafood sources was also below the established safe limits, concluding that regular consumption of these seafood options would not harmfully impact consumer health regarding nickel exposure.

For the first time, α-glucosidase, α-amylase, aldose reductase, and glycation at multiple stages inhibitory assays were used to explore the antidiabetic potential of whole unripe jackfruit (peel with pulp, flake, and seed). Two polyphenols (phenolic acids) with strong antihyperglycaemic activity were isolated from the methanol extract of whole jackfruit flour (MJ) using activity-guided repeated fractionation on a silica gel column chromatography. The bioactive compounds isolated were identified as 3-(3,4-Dihydroxyphenyl)-2-propenoic acid (caffeic acid: CA) and 4-Hydroxy-3,5-dimethoxybenzoic acid (syringic acid: SA) after various physicochemical and spectroscopic investigations.
