Maillard reaction is known to result in loss of nutrients, particularly that of essential amino acids; decrease in digestibility and safety issues due to the development of toxic compounds. Maillard reaction products are also known to cause oxidation of tissues and inflammation, thus increasing the risk of cardiovascular diseases and diabetes.

The first dispersive liquid liquid microextraction scheme followed by liquid chromatography‐post column derivatization for the determination of the antiviral drug – rimantadine – in urine samples is demonstrated. The effect of the type and volume of organic extraction solvent, type and volume of disperser solvent, sample pH, ionic strength, extraction time and centrifugation speed on the extraction efficiency were studied.

BACKGROUND Phthalates have been widely used as plasticizers in various industries and are widely focused on in the international community due to their reproductive toxicity. Recently, the exposure of Chinese residents to phthalates via edible vegetable oil often occurs.

The continuous release of anthropogenic pollutants into marine environment increases the needs for the development of analytical procedures for their accurate determination in many sample types. Sound strategies for seafood safety monitoring call for measurement systems capable of producing comparable analytical results with demonstrated quality. Method validation, traceability, and uncertainty of analytical results are the three milestones to assess data quality.

Q fever (caused by Coxiella burnetii) is a serious zoonotic disease that occurs almost worldwide. Occupational contact with animals increases the risk of exposure, and Q fever vaccination is recommended for veterinary workers in Australia. This study aimed to investigate C. burnetii seroprevalence among unvaccinated veterinary workers in Australia and determine factors associated with a positive serological result.

Background The objective of this study was to report an outbreak of human toxoplasmosis occurring in the municipality of Montes Claros de Goiás, Goiás, Brazil, from December 2015 to August 2016. Seven acute cases in June 2016 triggered the subsequent search. Methods A total of 251 individuals were selected through an active search, of which 114 (45.4%) agreed to participate in the research and blood collection.

Background Magnetic three‐dimensional graphene‐based nanoadsorbents (3DG‐Fe3O4) have unique characteristics such as large surface area, good thermal and chemical stability, and high adsorption capacity that make them efficient materials in sorbent‐based extraction techniques. In this study, four aflatoxins (B1, B2, G1, and G2) were analyzed in bread samples using magnetic three‐dimensional graphene as the adsorbent phase in dispersive micro‐solid phase extraction.

The chemical and anti-nutritional, antioxidative and anti-microbial properties of seeds from Acacia cyclops, Acacia microbotrya and Acacia victoriae(which are legumes) traditionally consumed by indigenous Western Australians were studied for the first time for their potential as commercial food components. A. microbotrya (2.7 CIU/g) (α < 0.05) had the highest α-chymotrypsin inhibitor activity, while A.

Treatment for patients with interstitial cystitis/bladder pain syndrome (IC/BPS) is always challenging for urologists. The main mechanism of the botulinum toxin A (BoNT-A) is inhibition of muscle contraction, but the indirect sensory modulation and anti-inflammatory effect in the bladder also play important roles in treating patients with IC/BPS. Although current guidelines consider BoNT-A injection to be a standard treatment, some practical issues remain debatable.

The health burden of foodborne mycotoxins is considerable, but particularly for children due to their lower detoxification capacity, rapid growth and high intake of food in proportion to their weight. Through a Total Dietary Study approach, the objective was to estimate the dietary exposure and health risk caused by mycotoxins for children under 5 years living in the Lao Cai province in northern Vietnam.

Defeat of the antibiotic resistance of pathogenic bacteria is one great challenge today and for the future. In the last century many classes of effective antibacterials have been developed, so that upcoming resistances could be met with novel drugs of various compound classes. Meanwhile, there is a certain lack of research of the pharmaceutical companies, and thus there are missing developments of novel antibiotics. Gram-positive bacteria are the most important cause of clinical infections.
