Relationships between the Content of Micro- and Macroelements in Animal Samples and Diseases of Different Etiologies. Animals (Basel) 2023; 13:ani13050852. [PMID: 36899709 PMCID: PMC10000063 DOI: 10.3390/ani13050852] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2022] [Revised: 02/14/2023] [Accepted: 02/17/2023] [Indexed: 03/03/2023] Open
Abstract
Many of the micro- and macro-elements (MMEs) required by the body are found in environmental objects in concentrations different from their original concentration that can lead to dangerous animal diseases ("microelementoses"). The aim was to study the features of MME (accumulating in wild and exotic animals) in connection with particular diseases. The work using 67 mammal species from four Russian zoological institutions was completed in 2022. Studies of 820 cleaned and defatted samples (hair, fur, etc.) after "wet-acid-ashing" on an electric stove and in a muffle furnace were performed using a Kvant-2A atomic absorption spectrometer. The content of zinc, copper, iron, cadmium, lead, and arsenic was assessed. The level of MME accumulation in the animal body contributes not only to the MME status and the development of various concomitant diseases, but the condition itself can occur by intake of a number of micronutrients and/or drugs. Particular correlations between the accumulation of Zn and skin, oncological diseases, Cu-musculoskeletal, cardiovascular diseases, Fe-oncological diseases, Pb-metabolic, nervous, oncological diseases, and Cd-cardiovascular diseases were established. Therefore, monitoring of the MME status of the organism must be carried out regularly (optimally once every 6 months).

[PMID: 33081049 PMCID: PMC7589941 DOI: 10.3390/v12101179] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2020] [Revised: 10/05/2020] [Accepted: 10/12/2020] [Indexed: 02/08/2023] Open
Abstract
Liquid-liquid phase separation (LLPS) is a rapidly growing research focus due to numerous demonstrations that many cellular proteins phase-separate to form biomolecular condensates (BMCs) that nucleate membraneless organelles (MLOs). A growing repertoire of mechanisms supporting BMC formation, composition, dynamics, and functions are becoming elucidated. BMCs are now appreciated as required for several steps of gene regulation, while their deregulation promotes pathological aggregates, such as stress granules (SGs) and insoluble irreversible plaques that are hallmarks of neurodegenerative diseases. Treatment of BMC-related diseases will greatly benefit from identification of therapeutics preventing pathological aggregates while sparing BMCs required for cellular functions. Numerous viruses that block SG assembly also utilize or engineer BMCs for their replication. While BMC formation first depends on prion-like disordered protein domains (PrLDs), metal ion-controlled RNA-binding domains (RBDs) also orchestrate their formation. Virus replication and viral genomic RNA (vRNA) packaging dynamics involving nucleocapsid (NC) proteins and their orthologs rely on Zinc (Zn) availability, while virus morphology and infectivity are negatively influenced by excess Copper (Cu). While virus infections modify physiological metal homeostasis towards an increased copper to zinc ratio (Cu/Zn), how and why they do this remains elusive. Following our recent finding that pan-retroviruses employ Zn for NC-mediated LLPS for virus assembly, we present a pan-virus bioinformatics and literature meta-analysis study identifying metal-based mechanisms linking virus-induced BMCs to neurodegenerative disease processes. We discover that conserved degree and placement of PrLDs juxtaposing metal-regulated RBDs are associated with disease-causing prion-like proteins and are common features of viral proteins responsible for virus capsid assembly and structure. Virus infections both modulate gene expression of metalloproteins and interfere with metal homeostasis, representing an additional virus strategy impeding physiological and cellular antiviral responses. Our analyses reveal that metal-coordinated virus NC protein PrLDs initiate LLPS that nucleate pan-virus assembly and contribute to their persistence as cell-free infectious aerosol droplets. Virus aerosol droplets and insoluble neurological disease aggregates should be eliminated by physiological or environmental metals that outcompete PrLD-bound metals. While environmental metals can control virus spreading via aerosol droplets, therapeutic interference with metals or metalloproteins represent additional attractive avenues against pan-virus infection and virus-exacerbated neurological diseases.

Abstract
Copper (Cu) and zinc (Zn) are essential trace elements for regular development. Acute infections alter their metabolism, while deficiencies increase infection risks. A prospective observational case-control study was conducted with infected (n = 21) and control (n = 23) term and preterm newborns. We analyzed trace element concentrations by X-ray fluorescence, and ceruloplasmin (CP) by Western blot. Median concentration of Cu at birth (day 1) was 522.8 [387.1-679.7] μg/L, and Zn was 1642.4 ± 438.1 μg/L. Cu and Zn correlated positively with gestational age in control newborns. Cu increased in infected newborns from day 1 to day 3. CP correlated positively to Cu levels at birth in both groups and on day 3 in the group of infected neonates. The Cu/Zn ratio was relatively high in infected newborns. Interleukin (IL)-6 concentrations on day 1 were unrelated to Cu, Zn, or the Cu/Zn ratio, whereas C-reactive protein (CRP) levels on day 3 correlated positively to the Cu/Zn -ratio at both day 1 and day 3. We conclude that infections affect the trace element homeostasis in newborns: serum Zn is reduced, while Cu and CP are increased. The Cu/Zn ratio combines both alterations, independent of gestational age. It may, thus, constitute a meaningful diagnostic biomarker for early-onset infections.

Abstract
The possibility to have reference values in clinical chemistry is really important and hair is an ideal tissue for tracing human health conditions. This study performed on 131 hair samples of high school students gives a better knowledge of element levels (i.d., As, Cd, Cr, Cu, Fe, Hg, Mn, S, Sb, Se, Sn and Zn) in subjects not exposed to specific contamination. A nuclear analytical technique, Instrumental Neutron Activation Analysis, has been employed for determining such species. These data can be used as tentative reference values in human hairs. The ratios among metals give important considerations on the general aspect of human health: the reference value represents an evaluation of the essential metabolic functions whereas an imbalance could be a factor influencing the rising of some pathologies, even if it is not an index of particular metabolic deficiency. A comparison with Italian studies shows a good agreement whereas some little discrepancies are evident with International studies. Further, a statistical approach (cluster analysis, Canonical Discriminant Analysis) was applied for determining the reference values. Taking in account these reference values a relationship with the environmental and pollutant compartments was studied confirming the starting hypothesis.

Abstract
Ninety-six untreated patients with malignant lymphoma (ML), 81 Hodgkin's disease, and 15 Burkitt's lymphoma were studied for zinc (Zn) status, and 21 patients also had selenium (Se) status analysis. Plasma and hair Zn and Se levels were measured by atomic absorption spectrophotometry. Chronic Zn and Se deficiencies (low plasma and low hair Zn and Se levels together) were found to be associated with ML in Turkish children. This was most likely due to the poor "nutritional environment" of the patients because majority of the ML patients were from families of low socioeconomic status. Supplementation of pediatric ML patients with Zn and Se, in addition to standard chemotherapy and radiotherapy regimen, is recommended.

Abstract
Birth weight is a popular topic, because it is precisely recorded, a major determinant of infant survival, associated with infant mortality, and health outcomes later in life. Low birth weight (LBW) is a predisposing factor for metabolic abnormalities such as atherosclerosis, renal disease, non-insulin diabetes mellitus, asthma, low IQ, hypertension, obesity, psychological distress. They have all been reported to be more common among those who were small at birth. Due to lack of studies suggesting a linkage between LBW and diseases of liver; evidences, which support the hypothesis on the creation of a link between LBW, an indicator of unfavourable intrauterine environment, and liver diseases emerging in the adult life, and possible direct associations of LBW with liver diseases, e.g., hepatitis, non-alcoholic fatty liver disease, cirrhosis, hepatoblastoma, or hepatocellular carcinoma were discussed. The associations between LBW and hepatitis vaccination as well as paediatric parental nutrition were also noted.

Abstract
Magnesium and zinc are the elements having essential roles in regulation of cell growth, division and differentiation. There have been some studies in the literature suggesting an association between the deficiency of these elements and the development of malignant disorders. In this study hair and serum zinc and magnesium levels were investigated in children with acute lymphoblastic leukemia (ALL) and malignant lymphoma (ML) at the time of initial diagnosis. Ten children with T-cell ALL, 10 children with B-precursor ALL, 5 children with Burkitt's Lymphoma (BL), 11 children with Hodgkin's lymphoma (HL), 10 children with non-Burkitt non-Hodgkin's lymphoma (NBNHL) and 12 age and sex matched healthy children as a control group were included in the study. Mean hair magnesium levels in all of the groups of the patients were lower than the levels in the control group but the difference was statistically significant only in the children with T cell ALL comparable to the controls (28.9+/-3.9 microg/g and 87.6+/-18.5 microg/g respectiveley, p<0,05). Mean serum magnesium levels in all the cohorts were not significantly different than those in controls (p>0.05 in each comparison). Mean hair zinc levels in the patients with T-cell, B-precursor ALL, BL, HL, NBNHL were 103.4+/-14.6 microg/g, 100.9+/-7.8 microg/g, 91.1+/-19 microg/g, 72.5+/-9.1 microg/g, 103.2+/-12.2 microg/g respectively. Each of these levels were significantly lower than the mean hair zinc levels of the control group (141.2+/-9.6 microg/g, p<0.05 in each comparison). Although mean serum zinc levels in all of the groups were also decreased, the differences were statistically significant only in the groups with B-precursor ALL, HL and NBNHL (75.9+/-5.29 microg/dl, 68.6+/-7.3 microg/dl, 85.7+/-5.5 microg/dl respectively) when compared with controls (105.1+/-9.9 microg/dl, p<0.05 in each comparison). Hair magnesium and zinc levels showed a positive correlation with each other in all the groups (r congruent with 0.5). No significant difference was found in the mean hair/serum magnesium and zinc levels between malnourished and nonmalnourished patients. In conclusion, regarding the results of our study and previous data in the literature chronic magnesium and zinc deficiency seems to be associated with the development of ALL and malignant lymphoma in a group of patients.

Abstract
Geographic differences in childhood cancer occurrence have been of great interest and have contributed to the current notion that most cancer cases are caused by environmental and cultural factors. The toxins, some of which are encountered by the general population, such as commonly used drugs, household products, solvents, pesticides, and insecticides, have been implicated as carcinogens and are factors that may add to the childhood cancer incidence in Turkey. Lack of information relevant to the disease, low family income, low educational status of parents, cessation of therapy, uncertainty about the child's future, fear for the child's survival, anxiety over the treatment and its effect as well as some cultural and traditional factors, are the basic individual characteristics of the population that interfere with the successful treatment of children with cancer in Turkey. Because the child with cancer is under enormous physical and emotional stress, appropriate psychosocial resources for the patient and family are important for optimal therapy. Community resources, healthcare services, income maintenance, medical insurance, financial assistance for treatment expenditures for the families who have children with cancer are extremely limited. These parameters are the unanswered needs which cancer patients and families face in our society. Despite impressive improvements, major problems remain to be solved.
