Abstract
Collective use center is an organization or structural unit with unique resource providing access to this resource for internal and third-party users. Collective use centers are a relatively new phenomenon in bioresource collections, especially collections of human biological material due to some ethical and legal issues. At the same time, the demand for human biological material continues to grow in fundamental and applied researches. The collective use center «Bioresource collection of tissues and cell cultures of tumors of the human nervous system for fundamental and applied researches» has worked since October 14, 2022. This center has access to unique collection of the Laboratory of Neurosurgical Anatomy and Conservation of Human Biological Tissues of the Burdenko Neurosurgical Center. OBJECTIVE To analyze the experience of collective use center and biobank of the Burdenko Neurosurgical Center compared to national and international data on functioning of collective use centers specializing in tumors of the human central nervous system. MATERIAL AND METHODS We reviewed the PubMed and e-Library databases using the following keywords: core facilities brain tumors, repository of collective use brain tumors, biobank of CNS tumors, central nervous system tumor collection centers. We also analyzed the organizations registered on the portal of scientific and technical infrastructure of the Russian Federation. RESULTS We analyzed 275 publications devoted to collective use centers and biobanks. These biobanks do not position themselves as collective use centers but actively realize biological material for researches. Structure of institutions presented on the portal of scientific and technical infrastructure of the Russian Federation is characterized. The collective use center «Bioresource collection of tissues and cell cultures of tumors of the human nervous system for fundamental and applied researches» has access to biobank of the Burdenko Neurosurgical Center. To date, the biobank contains more than 8478 aliquots of tumor tissue frozen at ultra-low temperature (-196°C) and obtained from 1993 patients. Considering available data, we established the basic principles of work in collective use centers with bioresource collections. CONCLUSION Collective use centers with bioresource collections of tumors of the central nervous system are rare. There is only one collective use center organized at the Burdenko Neurosurgical Center on the portal of scientific and technical infrastructure of the Russian Federation. At the same time, there is an urgent need to increase their number and activity in Russia and other countries worldwide. You can use the resource of brain tumor collections by leaving a request on the official website of this organization in the «Collective use center» section.

Revisiting Genetic Influence on Mercury Exposure and Intoxication in Humans: A Scoping Review. TOXICS 2023; 11:967. [PMID: 38133368 PMCID: PMC10747380 DOI: 10.3390/toxics11120967] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/27/2023] [Revised: 11/21/2023] [Accepted: 11/26/2023] [Indexed: 12/23/2023]
Abstract
Human intoxication to mercury is a worldwide health problem. In addition to the type and length of exposure, the genetic background plays an important role in mercury poisoning. However, reviews on the genetic influence in mercury toxicity are scarce and not systematic. Therefore, this review aimed to systematically overview the most recent evidence on the genetic influence (using single nucleotide polymorphisms, SNPs) on human mercury poisoning. Three different databases (PubMed/Medline, Web of Science and Scopus) were searched, and 380 studies were found that were published from 2015 to 2022. After applying inclusion/exclusion criteria, 29 studies were selected and data on characteristics (year, country, profile of participants) and results (mercury biomarkers and quantitation, SNPs, main findings) were extracted and analyzed. The largest number of studies was performed in Brazil, mainly involving traditional populations of the Tapajós River basin. Most studies evaluated the influence of the SNPs related to genes of the glutathione system (GST, GPx, etc.), the ATP-binding cassette transporters and the metallothionein proteins. The recent findings regarding other SNPs, such as those of apolipoprotein E and brain-derived neurotrophic factor genes, are also highlighted. The importance of the exposure level is discussed considering the possible biphasic behavior of the genetic modulation phenomena that could explain some SNP associations. Overall, recommendations are provided for future studies based on the analysis obtained in this scoping review.

JOURNAL OF ENVIRONMENTAL HEALTH SCIENCE & ENGINEERING 2023; 21:201-213. [PMID: 37159736 PMCID: PMC10163180 DOI: 10.1007/s40201-023-00853-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/16/2022] [Revised: 01/14/2023] [Accepted: 01/25/2023] [Indexed: 05/11/2023]
Abstract
Purpose Heavy metals and metalloids are recognized as environmental threats, which are considered highly toxic and carcinogenic. Epidemiologically, their association with leukemia is under debate. We aim to clarify the association between the heavy metal(loid)s in serum and leukemia via a systematic review and meta-analysis. Methods We searched PubMed, Embase, Google Scholar, and CNKI (China National Knowledge Infrastructure) databases for all related articles. The standardized mean difference and its 95% confidence interval was used to evaluate the association of leukemia with heavy metal(loid)s in serum. The statistical heterogeneity among studies was assessed with the Q-test and I 2 statistics. Results Among 4,119 articles related to metal(loid)s and leukemia, 21 studies met our inclusion criteria, which are all cross-sectional studies. These 21 studies involved 1,316 cases and 1,310 controls, based on which we evaluate the association of heavy metals/metalloids in serum with leukemia. Our results indicated positive differences for serum chromium, nickel, and mercury in leukemia patients, while a negative difference for serum manganese in acute lymphocytic leukemia (ALL). Conclusion Our results suggested an elevated trend of serum chromium, nickel, and mercury concentrations in leukemia patients while descending trend of serum manganese concentration in ALL patients. The result of sensitivity analysis between lead, cadmium, and leukemia and publication bias of association between chromium and leukemia also needed attention. Future research work may focus on the dose-response relationship between any of these elements and the leukemia risks, and further elucidation of how these elements are related to leukemia may shed light on the prevention and treatment of leukemia.

Methylmercury promotes oxidative stress and autophagy in rat cerebral cortex: Involvement of PI3K/AKT/mTOR or AMPK/TSC2/mTOR pathways and attenuation by N-acetyl-L-cysteine. Neurotoxicol Teratol 2023; 95:107137. [PMID: 36403891 DOI: 10.1016/j.ntt.2022.107137] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2022] [Revised: 11/13/2022] [Accepted: 11/13/2022] [Indexed: 11/19/2022]
Abstract
Methylmercury (MeHg) is a potent neurotoxicant that could induce oxidative stress and autophagy. However, the underlying mechanisms through which MeHg affects the central nervous system have not been fully elucidated, and little has been known of the interaction between oxidative stress and autophagy. Therefore, rats were administrated with different MeHg concentrations to evaluate the neurotoxic effects and autophagy in cerebral cortex. Moreover, we have investigated the neuroprotective role of N-acetyl-L-cysteine (NAC) against MeHg-induced neurotoxicity in order to estimate the regulation effects of oxidative stress on autophagy. A total of 64 rats, 40 of which were randomly divided into control and MeHg-treated (4, 8 and 12 μ mol/kg) groups. The remaining 24 rats were divided into control, NAC control (1 mmol/kg), 12 μ mol/kg MeHg, and NAC pretreatment. Administration of 12 μ mol/kg MeHg significantly increased behavioral and pathological abnormalities, and autophagy levels. In addition, the oxidative stress levels increased, together with abnormal expression of autophagy-related molecules. Pretreatment with NAC significantly prevented MeHg-induced oxidative stress and PI3K/AKT/mTOR or AMPK/TSC2/mTOR-mediated autophagy. In conclusion, the present study suggested that oxidative stress can regulate autophagy through PI3K/AKT/mTOR or AMPK/TSC2/mTOR pathways. This study provides a theoretical basis for the study and treatment of MeHg-induced neurotoxicity.

Abstract
Honey is a highly valued product due to its nutritional value, pro-health and healing properties. Pollutants from the environment penetrate into nectar, honeydew, pollen and next into bee products and can cause human exposure after ingestion. Mercury (Hg) is a toxic metal to living organisms. This is why it was important to determine the level of Hg in consumed honey.The aim of this manuscript is to analyse mercury concentration in honeys collected on the territory of Poland. A total of 108 samples of honey purchased in regional apiaries and hypermarkets were tested. The concentration of Hg was analysed in various types of honey (multifloral, honeydew, linden, goldenrod, acacia, buckwheat, rapeseed, sunflower, heather, dandelion, phacelia). The values of the Estimated Daily Intake (EDI), Estimated Weekly Intake (EWI) and % Provisional Tolerable Weekly Intake (% PTWI) were calculated. This allowed estimating the amount of Hg taken during consumption of the tested honeys.The concentration of Hg ranged from 0.01 to 1.71 µg/kg and was 0.43 µg/kg on average. A higher concentration of Hg, which was statistically significant, was recorded in honeydew honey, then in compound honeys. Honeys produced from one raw material had the lowest concentration of Hg. There were no significant differences in the concentration of Hg depending on the origin of honey. The calculations have shown that consumption of a portion (19 g) of the tested honey per week is safe for both adults and children according to the applicable standards.

Abstract
Mercury (Hg) is an environmental contaminant that poses great risk to human health. However, it is still widely used in artisanal gold-mining enterprises around the world, especially in developing countries. Methylmercury (MeHg) is produced environmentally by biomethylation of inorganic Hg present in water sediments, leading to its subsequent accumulation in the aquatic food chain. Due to its high metabolic rate, the Central Nervous System (CNS) is one of the main targets of MeHg. In the present study, we investigate the impact of chronic MeHg intoxication on NADPH diaphorase (NADPH-d) activity and astrocyte mobilization in the visual cortex of the rat. After 60 days of MeHg administration by oral gavage (0.04 mg/kg/day), tissue samples containing the visual cortex were submitted to measurements of Hg levels, NADPH-d activity, and GFAP immunohistochemistry for identification of astrocytes. MeHg intoxication was associated with increased Hg deposits and with reduced NADPH-d neuropil reactivity in the visual cortex. A morphometric analysis suggested that NADPH-d-positive neurons were mostly spared from MeHg harmful action and intoxicated animals had astrocytic activation similar to the control group. The decrease in NADPH-d neuropil reactivity may be due to the negative effect of chronic MeHg poisoning on both the synthesis and transport of this enzyme in afferent pathways to the visual cortex. The relative resistance of NADPH-d-reactive neurons to chronic MeHg intoxication may be associated with peculiarities in cell metabolism or to a protective role of nitric oxide, safeguarding those neurons from Hg deleterious effects.
