Cadmium (Cd) is a heavy metal that occurs in all areas of the environment, including the food chain. In the body, it causes oxidative stress by producing free radicals that are harmful to the cells. Grape seed extract (GSE) contains a wide range of biologically active components that help to neutralize the adverse effects of free radicals. In this study, the effects of GSE prepared form semi-resistant grapevine cultivar Cerason, which is rich in phenolics, on biochemical markers of brown rats exposed to the effects of cadmium were monitored. GSE increased the plasma antioxidant activity and, in the kidneys and the liver, Cd content was significantly lowered by GSE co-administration. Accordingly, the increase in creatinine content and alanine aminotransferase activity and the decrease of catalase and superoxide dismutase activities caused by cadmium were slowed down by GSE co-administration. The results of this work reveal that grape seed extract offers a protective effect against the intake of heavy metals into the organism.

This review is focused on the study of the effects of grape seed and skin extract (GSSE) on human health. GSSE contains high concentrations of important polyphenolic substances with high biological activity. This review is a summary of studies that investigate the effects of GSSE on diabetes mellitus, cardiovascular disease and cancer, its neuroprotective effect, and its effects on the gastrointestinal tract and other health complications related to these diseases. The results of the studies confirm that the anti-inflammatory, antiapoptotic, and pro-proliferative effects of "Vitis vinifera L." seed extract reduce the level of oxidative stress and improve the overall lipid metabolism.

OBJECTIVE: Vitamin D deficiency is a global health problem. The aim of this study was to determine the proportion of Czech children with vitamin D deficiency and examine related factors. METHODS: The study subjects were 419 healthy children aged 5 and 9 years. Severe vitamin D deficiency was defined as a serum 25(OH)D level of < 25 nmol/L (3% of children), deficiency as that of 25-50 nmol/L (24% of children), insufficiency as that of 50-75 nmol/L (40% of children) and sufficiency as that of > 75 nmol/L (34% of children). RESULTS: Serum 25(OH)D levels varied mainly with season. The highest levels of 25(OH)D were reached in autumn (median: 79.0 nmol/L), followed by summer (median: 67.8 nmol/L) and winter (median: 56.0 nmol/L). The lowest median value (49.8 nmol/L) was detected in spring. CONCLUSION: Children with sufficiency 25(OH)D levels were more frequently exposed to the sun and exposed a larger part of their body to the sun while spending time outdoors. Levels of 25(OH)D were also associated with using vitamin D supplements within six weeks before sampling.

Persistent organic pollutants, such as perfluorinated alkylated substances (PFASs) and brominated flame retardants (BFRs) are widespread in the environment and most of them are bioaccumulated in wildlife and humans. The present study is the first investigation to reveal the PFAS and BFR levels of serum samples in the adult population of the Czech Republic. Altogether, 300 serum samples from blood donors in four cities were examined. In all samples 19 PFASs and 33 BFRs, including some of their metabolites, were targeted. The analyses were performed using ultra high performance liquid chromatography coupled with tandem mass spectrometry or gas chromatography with mass spectrometry (according to the type of analyte). PFASs, with the carbon chain length C6 and higher, dominated in all samples. Perfluorooctanesulfonate (PFOS; median: 2.43ng/mL), perfluorooctanoic acid (PFOA; median: 0.756ng/mL), perfluorodecanoic acid (PFDA; median: 0.145ng/mL) and perfluorohexanesulfonate (PFHxS; median: 0.184ng/mL) were detected in 100% of samples. Perfluorononanoic acid (PFNA; median: 0.325ng/mL) and perfluoroundecanoic acid (PFUdA; median: 0.058ng/mL) in 99.7% and 96.0% of samples, respectively. We observed statistically significant associations (p<0.05) between selected PFAS concentrations and the locality, gender, age of donors and education level. None of the BFRs was detected above the LOQ in more than 9% of the samples. The most frequently detected representatives of this group were congeners of polybrominated diphenyl ethers, namely BDE-47 (in 8.7%; range: 0.496-5.44ng/g lipid weight (l.w.)), BDE-99 (in 6.0%; range: 0.706-9.46ng/g l.w.), BDE-153 (in 7.3%; range: 0.736-6.44ng/g l.w.) and BDE-209 (in 7.0%; range: 13.7-2693ng/g l.w.).
