Abstract

Aims

This research aimed to establish how Hordeum vulgare responds to abiotic and biotic stress affecting in tandem.

Bitis arietans is a snake of medical importance, as it is responsible for more accidents in humans and domestic animals than all other African snakes put together. The accidents are characterized by local and systemic alterations, such as inflammation, cardiovascular and hemostatic disturbances, which can lead victims to death or permanent disability.

The use of antimicrobial agents in livestock breeding is inevitable for prophylactic and treatment purposes, in order to maintain health and improve production of food products. However, this practice resulted in development of community resistance to antimicrobials due to residues found in livestock products. Milk is a key nutritional product that’s widely consumed for its high nutritional value.

Snack samples like potato crisp, fried potato, popcorn, and Cheetos have been known as carbohydrate- and protein-rich food. These tasty foods have high potential to contain acrylamide. Genotoxic and carcinogenic effect of acrylamide on human health cause to specific focus for measuring of acrylamide in food samples (Esposito et al. Food Chem Toxicol 108:249–256, 2017).

A double signal enhanced surface plasmon resonance (SPR) biosensor system was developed, which involved graphene-based magnetic dispersion solid-phase extraction (MDSPE) and carboxylated graphene oxide (GO-COOH) materials as amplifying elements in order to achieve real-time determinations of estradiol (E2), diethylstilboestrol (DES), and bisphenol A (BPA) via an indirect competition method.

Priority pollutants chlorophenols are broadly used chemicals that are persistent in the environment and causing serious human health hazards. The current study introduces a novel adsorbent for the extraction of chlorophenols from river water, surface water, and milk by headspace solid phase microextraction coupled with GC.

Some snails (Achatina spp) can be used as a biosensor of heavy metal poisoning. This study thus estimated some heavy metal levels, antioxidant markers, and lipid profiles of snails handpicked around cement factory vicinities in Ogun State, Nigeria. Snails and soil samples were collected from Oke, Ewekoro, Papalanto, and Mowodani Imeko-Afon (control site).

Aim:Bisphenol-A (BPA) is an endocrine disrupting compound and may exacerbate or induce allergic diseases. To the best of our knowledge, there is little evidence regarding the effects of BPA exposure on allergic rhinitis (AR) in children. In the present study, we sought to examine whether exposure to BPA in children is associated with AR.Methods:This study was designed as a case controlled clinical study.

Predictions of drug residues in milk are critical in food protection and are a major consideration in the economics of treatment of mastitis in dairy cows. Nonlinear mixed-effects modeling (NLME) has been advocated as a suitable pharmaco-statistical method for the study of drug residues in milk. Recent developments in physiologically based pharmacokinetic (PBPK) modeling of intramammary drugs allow the combination of a mechanistic description of milk pharmacokinetics with NLME methods.

To reduce the use of conventional chemical pesticides, naturally occurring biopesticides such as bacteriophages have emerged as a promising solution, but effectiveness of these biopesticides can be limited because of their UV and desiccation instability. This study developed a biopolymer formulation to improve the phage stability, enhance the antimicrobial activity of phages, and prevent bacterial contaminations on a leaf surface in the presence of UV-A.

Background and Aims Ozonated water has been used in vineyards to reduce the use of pesticides because of its presumed efficacy in the control of fungal diseases and the absence of residues. The aim of this study was to evaluate the effect of ozonated water treatments on the composition of grapes. Methods and Results Ozonated water was applied to grapevines of Vitis vinifera cv. Cabernet Sauvignon throughout the season.

Variation in inter‐human attractiveness to mosquitoes, and the preference of mosquitoes to bite certain regions on the human host, are possible avenues for identifying lead compounds as potential mosquito attractants or repellents.

BACKGROUND The contamination of milk by antibiotic residues represents risks to the health of the consumers, therefore they should be monitored.

For pesticide registration a post application assessment is made on the safety of any residue remaining in the edible portion of the treated crop. This assessment does not typically consider the bioaccessibility of pesticide residues. The effects of this on potential exposure to incurred difenoconazole residues passing through the human gastrointestinal tract were studied, including the impact of commodity processing.
