A zero-background method based on surface-enhanced Raman scattering (SERS) was developed for the rapid determination of cymoxanil residue in food. Because of the influence of complex matrices, conventional Raman spectroscopy has multiple peaks that overlap with those of target molecules, which makes qualitative and quantitative detection difficult.

Avocado Hass (Persea americana Mill) peel extract (APE) has the potential as a natural ingredient to substitute for chemical preservatives.

Antibiotic producers have mainly been isolated from soil, which often has led to the rediscovery of known compounds. In this study, we identified the freshwater snail Physa acuta as an unexplored source for new antibiotic producers. The bacterial diversity associated with the snail was characterized by a metagenomic approach using cultivation-independent high-throughput sequencing.

The role of ethylene in plant development is mostly inferred from its exogenous application. The usage of the mutants affecting ethylene biosynthesis proffers a better alternative to decipher its role. In tomato, 1‐aminocyclopropane carboxylic acid synthase2 (ACS2) is a key enzyme regulating ripening‐specific ethylene biosynthesis.

We conducted a pilot study to assess microbiological safety of chicken litter, an affordable organic and main fertilizer used in Cameroon and worldwide. A convenience sampling of 26 farms was done and a questionnaire was administered. Samples of litter were aseptically collected. E. coli and Salmonella spp. were isolated using CLSI standards. Antibiotic susceptibility testing was performed using the disc diffusion method and a micro broth dilution method for colistin.

Duck hepatitis A virus 1 (DHAV‐1) is a highly prevalent pathogen within adult ducks causing acute as well as chronic hepatitis which closely emulates the progression of human hepatitis. However, the underlying mechanisms of DHAV‐1 persistence and the pathogenesis of chronic liver disease are not well defined. The association between hematopoietic reservoirs of virus and persistent infection is increasingly concerning.

Scheme summarizing the protective properties of Chrysin against testicular toxicity caused by lead acetate in rats. Abstract In the present study, the protective effects of chrysin (CHR) against testicular damage caused by lead acetate (PbAc) were examined. In this way, 30 min after rats were given 25 and 50 mg/kg/b.w CHR orally for seven consecutive days, 30 mg/kg/b.w PbAc was administered orally.

The present study aimed to evaluate the effects of poly‐β‐hydroxybutyrate (PHB)‐supplemented diets for rainbow trout (Oncorhynchus mykiss) fingerlings. For this purpose, three experimental diets were prepared to contain 0, 2, and 5% PHB; and each diet was tested in a completely randomized design for 60 days in quadruple groups of 22 fish per tank.

The distribution of metals across the environment is increasingly becoming a major concern as they not only pollute the environment but also pose a danger to humans and animals. Human exposure to heavy metals often occurs as a combination of metals the synergistic effects of which can be more toxic than a single metal.

The aim of this study was to evaluate the concentration of penicillin G in bone affected by antiresorptive agent-related osteonecrosis of the jaw (ARONJ) following a single preoperative dose of 10 million international units (6000 mg). ARONJ is a major concern in patients administered antiresorptive agents for conditions associated with pathologically increased bone resorption.

BACKGROUND Chlorpyrifos (CPF) is a broad‐spectrum organophosphorus pesticide widely used to control tea geometrid (Ectropis oblique) and tea green leafhoppers (Empoasca pirisuga Matumura) in tea trees. The major metabolite of CPF in water, plants and animals is 3,5,6‐trichloro‐2‐pyridinol (TCP), which is more toxic than CPF. However, dissipation pattern of CPF in tea is unknown.

Background Pymetrozine is a widely used pesticide. It is challenging‐to‐analyse and difficult to manage due to the large gap in its global maximum residue limits (MRLs) in tea. Therefore, development of a high‐efficiency detection method for the evaluation of the transfer of residual pymetrozine from tea plantations to tea cups is of prime significance.

Rhamnolipid is the main group of biosurfactants predominantly produced by Pseudomonas aeruginosa, a ubiquitous and opportunistic pathogen, which limits its large-scale exploitation. Thus, cost-effective rhamnolipid production from a newly isolated nonpathogenic Enterobacter sp. UJS-RC was investigated. The highest rhamnolipid production (4.4 ± 0.2 g/L) was achieved in a medium constituting agroindustrial wastes (sugarcane molasses and corn steep liquor) as substrates.
