“…MJ was added to the medium in separate batches at concentrations of 5, 10, 15, 20, and 25 µmol•L −1 . For each treatment, 3 replicates were placed in the incubator and kept at 28 • C in the dark for 28 days [46]. The growth rate of T. camphoratus mycelia was observed, photographed, and recorded every 7 days, and the average growth rate was calculated using the cross intersect method.…”

A rare medicinal fungus called Taiwanofungus camphoratus gives people resistance to illness. In order to effectively obtain high−quality T. camphoratus mycelia, we added Cymbopogon citratus (lemongrass) water extract (LWE), which was prepared using hot water and dry lemongrass leaves and methyl jasmonate (MJ) as an additive, in order to cultivate T. camphoratus mycelia. The components of LWE were identified by gas chromatography–mass spectrometry as glucose (61.66%) and galactose (17.10%). Compare to the basal medium, 0.5–2.5 g·L−1 LWE and 5–25 μmol·L−1 MJ can enhance the proliferation of mycelia and the metabolism of polyunsaturated fatty acids (PUFAs). Among them, the T. camphoratus mycelia growth rate increased to 1.292 ± 0.01 cm·d−1 and 1.285 ± 0.05 cm·d−1, improving by 2.5 g·L−1 LWE and 25 μmol·L−1 MJ, respectively. PUFAs are mainly composed of linoleic acid (LA) and oleic acid (OA). The contents of LA and OA were 0.28 ± 0.02 mg·g−1 and 0.23 ± 0.05 mg·g−1 after MJ treatment, while the contents of LA and OA were 0.08 ± 0.03 mg·g−1 and 0.05 ± 0.05 mg·g−1 after LWE treatment. Transcriptome analyses revealed that 367 and 232 genes within MJ and LWE treatment were significantly different from the basal medium. Out of 13 unigenes, FAD2−2, SCD, and FAD2−1 had the highest expression levels according to the quantitative RT−PCR result. The bioinformatics analysis showed that three genes are closely related to the M8 chromosome of T. camphoratus, and they are hydrophobic transmembrane proteins. The identification and investigation of fatty acid genes in T. camphoratus mycelia will be improved by our findings.

“…In a study of closed-loop food webs in Inner Mongolia (27), the biological amplification of PcBs in mice to snakes was found to be >1,000 times, suggesting that the relatively low concentrations and low toxic equivalent concentrations at the bottom of the food chain are biomagnified at high trophic levels. Various studies have demonstrated that fish products are the main source of PcBs, and that their PcB content varies with the region and type of fish, while grains and vegetables contain fewer PCBs (28)(29)(30)(31). However, fish consumption in the general population is relatively low, suggesting that the health risks associated with exposure to PcBs have a certain tolerable daily intake (30).…”

The developmental origins of health and disease concept illustrates that exposure in early life to various factors may affect the offspring's long-term susceptibility to disease. during development, the nervous system is sensitive and vulnerable to the environmental insults. Polychlorinated biphenyls (PcBs), which are divided into dioxin-like (dL-PcBs) and non-dioxin-like PcBs (NdL-PcBs), are synthetic persistent environmental endocrine-disrupting chemicals. The toxicological mechanisms of dL-PcBs have been associated with the activation of the aryl hydrocarbon receptor and NdL-PcBs have been associated with ryanodine receptor-mediated calcium ion channels, which affect neuronal migration, promote dendritic growth and alter neuronal connectivity. In addition, PcB accumulation in the placenta destroys the fetal placental unit and affects endocrine function, particularly thyroid hormones and the dopaminergic system, leading to neuroendocrine disorders. However, epidemiological investigations have not achieved a consistent result in different study cohorts. The present review summarizes the epidemiological differences and possible mechanisms of the effects of intrauterine PcB exposure on neurological development.

The aim of the work was to measure the concentration of organochlorine insecticides, heavy metals, and hydrocarbons from the oil series in samples of marine fish from diverse oceans in the region. To achieve the goal, the methods of high-performance liquid chromatography and atomic absorption spectrometry, as well as the statistical method, were used. A total of 250 marine fish samples collected from the Caspian, Black, Baltic, Azov, and Okhotsk seas were analysed. The results of the study showed significant concentrations of organochlorine pesticides, including isomers of hexachlorocyclohexane (HCH), in fish living in the Caspian, Black and Baltic Seas. Specifically, the Caspian Sea is found to have the highest HCH content of 0.2123 mg/kg, while the Black Sea and Baltic Sea show 0.2031 mg/kg and 0.0187 mg/kg respectively. Heavy metals such as lead (Pb), cadmium (Cd), and chromium (Cr) have also been found in fish samples. A comparative analysis of the content of pollutants in marine fish of the Eurasian region allows to draw the following conclusions: in fish living in the Caspian, Black and Baltic seas, there is a high concentration of organochlorine pesticides, heavy metals and petroleum hydrocarbons. This indicates significant pollution of the marine ecosystem by these substances. These studies highlight the need to control pollution of marine fish with pollutants and monitor the state of marine ecosystems to ensure the safety of fish consumption and public health.
