Atherosclerosis precursors in Finnish children and adolescents. XIII. Serum and hair copper and zinc concentrations

Heavy metals are one of the most important pollutants released to the aquatic environment by the various industrial activities. The use of these wastewater for irrigation results accumulation of heavy metals in soil and plants. So, the present investigation deals with the various concentrations (0, 5, 10, 25, 50, 100, 200 and 300 mg/l) of copper and zinc on germination studies of soybean. The different concentrations of copper and zinc were used for germination studies. The seedlings were allowed to grow upto seven days. The studied morphological traits increased at 5 mg/l concentration and these parameters are gradually decreased with the increase of copper and zinc concentrations.

Objectives The aim of this study was to analyze iron, copper and zinc concentrations in commercial foods and compare among food formats (dry, canned, raw), foods marketed by age category (adult 1+ years and senior 7+ years) and foods intended for adult maintenance vs all life stages. Methods In total, 112 commercial non-therapeutic food products marketed for healthy adult and senior cats were purchased in the USA. Foods were analyzed for their proximate composition. Trace mineral concentrations were measured using inductively coupled argon plasma–optical emission spectroscopy and described on a calculated metabolizable energy basis using standard modified Atwater values. Results Measured iron (median 58.4 mg/1000 kcal [range 15.7–379.0]), copper (median 5.6 mg/1000 kcal [range 0.8–13.3]) and zinc (median 47.6 mg/1000 kcal [range 7.6–128.1]) concentrations were highly variable among cat foods. When all food products – regardless of their nutritional adequacy substantiation method – were compared with the Association of American Feed Control Officials regulatory minimums, 13/112 food products had a mineral deficiency, of which a majority (n = 11/13) were raw food products. Raw foods had significantly lower trace mineral concentrations compared with dry food products and, except for copper, canned food products. Cat foods marketed for senior cats had higher iron ( P = 0.019) and zinc ( P <0.0001) concentrations than foods marketed for adult cats. Foods intended for adult maintenance had higher iron ( P = 0.003) and zinc concentrations than foods intended for all life stages ( P <0.0001). Conclusions and relevance Iron, copper and zinc concentrations in commercial non-therapeutic foods for adult and senior cats are highly variable. A minority of foods – mainly raw food products – were deficient in these minerals. It is unknown if some foods with high trace mineral concentrations could have adverse effects as studies are needed to establish safe upper limits for dietary intake of trace minerals in healthy cats.

Abstract Purpose Zinc plays an important role in metabolic processes in human organisms and is indispensable in many enzymatic processes. To date, few studies have assessed the association between serum zinc and metabolic risk factors in children and adolescents. The aim of the present study was to examine whether serum zinc concentrations was associated with metabolic risk factors in Chinese children and adolescents. Methods This study was a cross-sectional analysis of data from the 2016-2017 China National Nutrition and Health Surveillance for Children and Nursing in Jiangsu Province. A total of 3241 participants aged 6 -17years were included. Metabolic risk factors included fasting glucose (FG), total cholesterol (TC), triglycerides (TG), high-density lipoprotein (HDL-C), low-density lipoprotein (LDL-C), systolic blood pressure and diastolic blood pressure. Data were analyzed using multivariable linear regression and generalized additive models, which were adjusted for age, gender, high sensitive C-reactive protein, estimated glomerular filtration rate, body mass index and region of residence, to assess the associations of serum zinc concentrations with metabolic risk factors. Results We observed a negative association between serum zinc concentrations and FG (coefficient = -0.532; 95% CI: -0.569, -0.495; p< 0.001). Moreover, TC (coefficient = 0.175 ; 95% CI 0.127, 0.222; p< 0.001), HDL-C (coefficient = 0.137 ; 95% CI 0.082, 0.193; p< 0.001) and LDL-C (coefficient = 0.195 ; 95% CI 0.128, 0.263; p< 0.001) were found to be positively associated with zinc levels. A generalized additive model showed that the negative association between serum zinc and FG was weak at lower serum zinc concentrations, and was stronger with the increase in serum zinc concentrations. Additionally, a U-shaped association between serum zinc and TG was observed. Conclusions Serum zinc concentrations were associated with FG, TC, TG, HDL-C and LDL-C levels in Chinese children and adolescents. Lower levels of serum zinc were more likely related to a poor metabolic status.

Analysis of the total copper and zinc content of four species of talitrid amphipods, Orchestia gammarellus, O. mediterranea, Talitrus saltator and Talorchestia deshayesii throughout a complete spring/neap tidal cycle failed to reveal any significant effects of moulting upon body copper or zinc in any species. Moulting was synchronized to the lunar cycle only in T. saltator, taking place 5–7 days prior to a new moon. The fact that no significant changes in body metal concentrations took place with the moult cycle is discussed in relation to the use of talitrid amphipods in copper and zinc biomonitoring programmes.

The Difference

Background: The aim of present study was to determine the role of trace elements copper and zinc and impairment of infertility.Methods: The study was a randomized, comparative, clinical trial where study group included 74 patients with primary or secondary infertility and control group included 20 patients who were fertile females of reproductive age group having no gynaecological or systemic disease. Venous blood samples were taken and plasma copper and zinc concentrations were measured.Results: In the normal fertile non-pregnant healthy female’s plasma copper ranged from 98.78 - 169.2 mcg% (mean 124.72 mcg%). In patients of unexplained infertility plasma copper was found to be low. It ranged from 63.0 - 145.14 mcg% (mean 95.5 mcg%) difference being statistically significant, (P<0.001). The difference in plasma zinc concentration in both group was not statically significant (P>0.05).Conclusions: Our results show that copper deficiency might have a role to play in the etiogenesis of otherwise unexplained infertility. We can also conclude that zinc deficiency may not play a significant role in female infertility.
