Background: Aortic valve sclerosis (AVSc) is defined as the thickening and calcification of aortic valve cusps, in the absence of obstruction of ventricular outflow. AVSc is linked with a clear imbalance in some trace elements. Aims: The objective of this study was to investigate the relationship between AVSc and serum levels of iron (Fe), zinc (Zn), selenium (Se), and copper (Cu). Additionally, this research aimed to explore the clinical significance of human serum zinc, selenium, copper, and iron concentrations as a potential new biomarker for AVSc patients and to clarify the pathophysiological role in individuals at risk of developing AVSc. Patients and methods: The study included 40 subjects with AVSc (25% male and 75% female) who were compared with a healthy control group with the same gender ratio. AVSc was based on comprehensive echocardiographic assessments. Blood samples were taken and Zn and Cu concentrations were determined through the use of atomic absorption spectroscopy. Se was measured using an inductively coupled plasma mass spectrometry device and Fe was measured using a Beckman Coulter instrument. Results: There was a significant difference in the prevalence of diabetes, blood pressure levels, and body mass index between the patients and the healthy subjects ( p < 0.05). The differences between the serum Fe, Se, and Cu levels of the AVSc patients and the healthy subjects ( p > 0.05) were recorded. The serum Zn of AVSc patients when compared was significantly lower compared with that of the control group ( p < 0.01). Conclusion: Patients with AVSc had an imbalance in some of the trace elements in their blood. The patient group’s valves had higher serum Cu levels and lower serum Se, Zn, and Fe concentrations compared with the healthy group’s valves. In the valve patients as compared, AVSc had a high prevalence of obesity, hypertension, and diabetes.

Background: This study aims to determine and compare the levels of trace elements copper, zinc, selenium and chromium in GCF and serum of patients with periodontitis and healthy individuals. Methods: This cross sectional study includes 24 study subjects recruited from the patients reporting to the Department of Periodontics , Tagore Dental College Chennai. All the selected patients were subjected to a clinical examination done by a single examiner. The estimation of trace elements Copper, Zinc, Selenium and Chromium in GCF and serum is performed using Perkin Elmer optima 5300 Inductively Coupled Plasma Emission Spectrometer (ICPOES). Results: GCF and serum copper levels showed no significant difference in both periodontitis and healthy groups . Selenium levels tend to be the same in both groups. Serum zinc levels are more in periodontitis patients than healthy subjects (p less than 0.01). GCF chromium levels are found to be more in patients with periodontitis than healthy. Conclusions : More research is therefore needed to monitor the role of these trace elements C with an increased sample size to ascertain whether they are associated with a reduced risk of periodontitis.

The procedure of restorative proctocolectomy is associated with a complete removal of the colon and slight reduction of ileum length, which together can lead to systemic shortages of trace elements. Inflammatory changes in the pouch mucosa may also have some impact. However, there is no data on trace elements in pouchitis. Therefore, in the present study we aimed to assess the effect of acute pouchitis on the status of selected trace elements in rats. Restorative proctocolectomy with the construction of intestinal J-pouch was performed in twenty-four Wistar rats. Three weeks after the surgery, pouchitis was induced. Eight untreated rats created the control group. Liver concentrations of selected micronutrients (Zn, Cu, Co, Mn, Se) were measured in both groups six weeks later, using inductively coupled plasma mass spectrometry. Liver concentrations of trace elements did not differ between the study and the control groups. However, copper, cobalt and selenium concentrations [μg/g] were statistically lower (p

Abstract Background Inductively coupled plasma is widely used for elemental analysis with the advantage of being eco-friendly since the discharge is free of contaminants. Objective A rapid, novel method was developed for the quantitation of trace elements using inductively coupled plasma with optical emission spectrometry.This method has the advantage of simultaneous calibration compared to the conventional method. Method The assay was carried out for iron, copper, zinc, and molybdenum using the linear regression model partial least-squares. Results The method was optimized and validated as per the International Conference on Harmonization guidelines, showing highly accurate and precise results. The linearity range was 0.25–4 ppm for all trace elements under investigation. The method was applied for the assay of the cited elements in non-chelated and amino acid chelated multi-mineral preparations in the Egyptian market with acceptable mean percent recovery. Conclusions In comparison with the official method by flame emission, statistical analysis showed no significant difference with Student’s t-test and F-values. Highlights Inductively coupled plasma is superior as all of the elements can be measured simultaneously. The method was found to have a high degree of specificity and can be easily applied in routine elemental analysis in laboratories.

AimTo investigate the effect of the pasteurisation process on trace elements in donor breast milk.MethodPremature infants often receive donor breast milk when the mother is unable to produce sufficient breast milk. It is widely accepted that donor milk has considerable advantages over formula milk.1 The Royal Brisbane and Women's Hospital (RBWH) has a milk bank that receives milk donated by women which undergoes a pasteurisation process.2 This study investigated the effect of pasteurisation on a range of trace elements in donor milk.A total of 14 participants who donated to the milk bank were recruited in this study. A 2 ml sample was collected pre- and post- pasteurisation, and frozen at −80 °C. Post-natal age of the milk was documented. Inductively-coupled plasma mass-spectrometry was used to analyse the following trace elements – zinc (Zn), copper (Cu), selenium (Se), manganese (Mn), iodine (I), iron (Fe), molybdenum (Mo) and bromine (Br). The study received ethical approval from RBWH and The University of Queensland Ethics Committee.ResultsNo significant difference was found between the levels of any of the trace elements tested pre- and post-pasteurisation. The following p-values were calculated – Zn (0.82), Cu (0.80), Se (0.97), Mn (0.63), I (0.99), Fe (0.05), Mo (0.41), Br (0.59). The following ranges in mcg/L of trace elements were calculated – Zn (365.4–5460.0), Cu (157.6–820.5), Se (10.6–23.7), Mn (0.55–3.24), I (66.4–215.3), Fe (101.5–473.1), Mo (0.20–5.45), Br (704.9–3379.0). Spearman's rank correlation analysis showed significant correlations between post-natal age of milk and trace elements – Zn (ρ=−0.578), Se (ρ=−0.627). Fe (ρ=−0.704), and Mo (ρ=−0.534). No significant correlation was found for Cu, Mn, I, and Br.ConclusionThis study found that the pasteurisation process had minimal effect on trace element levels in donor breast milk. However, it was noted that there was a correlation between post-natal age of donor milk and Zn, Se, Fe and Mo. Further work is needed to establish factors that may influence levels of trace elements in donor milk such as post-natal age.

Lead acetate (300 mg/L) and/or cadmium chloride (50 mg/L) were administered as drinking water to Sprague-Dawley rats for 9 weeks to investigate the effects of concurrent exposure to lead and cadmium on the distribution patterns of five essential trace elements. Inductively coupled plasma mass spectrometry was used to determine the concentrations of zinc, copper, manganese, selenium and iron in the urine at different exposure times, as well as their levels in the renal cortex and serum at the end of treatment. Compared with the control group, exposure to lead and/or cadmium resulted in a significant increase in the urinary excretion of these five elements during the experiment, whereas significant decreased levels of these elements were found in kidney and serum. In conclusion, increased urinary loss of antioxidant trace elements due to lead and/or cadmium exposure induced the deficiency of antioxidants in the body, which could result in further oxidative damage. Moreover, there was an obvious synergistic effect of lead combined with cadmium on the distribution patterns of these essential trace elements, which may be related to the severity of co-exposure to these two metals.

Background. Mouthwashes are widely used as adjuncts to mechanical oral hygiene procedures. Nonetheless, there is little information regarding the effect of various mouthwashes on the amount of ions released from the nickel-chromium (Ni‒Cr) alloys used in the fabrication of fixed prostheses. Therefore, the present study was conducted to evaluate the effect of two types of mouthwash on the release of Ni ions from dental alloys. Methods. Forty-two disk-shaped specimens were prepared with a diameter of 10 mm and a height of 2 mm. Two mouthwashes were examined in this study: Oral B and Listerine. A control group was also considered using distilled water. Each Ni‒Cr disk was immersed in the mouthwashes and distilled water in polypropylene test tubes, and then incubated at 37°C to simulate the oral temperature. After 45 days of incubation, the samples were tested for Ni ions using inductively coupled plasma mass spectroscopy. Data were analyzed using ANOVA. Results. In the Halita group subjects exhibited 2.04±0.65 reduction in OLS. OLS reduction in the chlorhexidine group was 1.95±0.74. Statistical analysis showed no significant difference between the two groups (P>0.05). Conclusion. As the results indicated, the amount of ion release was within the safe limits in the two experimental groups. However, it is recommended that prescribe Listerine mouthwash should not be prescribed for the patients with a history of Ni allergy.

The aim of this study was to determine if altered levels of selected trace elements manifest themselves during chronic depression. To identify elements strongly associated with chronic depression, relationships between the elemental contents of hair and nails and the interelement correlations were checked. Inductively coupled plasma mass spectrometry and ion chromatography were used to evaluate the contents of Zn, Cu, Co, Pb, Mn, and Fe in hair and nail samples from a total of 415 subjects (295 patients and 120 healthy volunteers). The study included logistic regression models to predict the probability of chronic depression. To investigate possible intercorrelations among the studied elements, the scaled principal component analysis was used. The research has revealed differences in TE levels in the group of depressed men and women in comparison to the healthy subjects. Statistically significant differences in both hair and nails contents of several elements were observed. Our study also provides strong evidence that the intermediary metabolism of certain elements is age- and gender-dependent. Zn, Mn, Pb, and Fe contents in hair/nails seem to be strongly associated with chronic depression. We found no statistically significant residence-related differences in the contents of studied elements in nonoccupationally exposed patients and healthy subjects.

Objective: Aortic valve sclerosis (AVS) is a progressive disease that is characterized by aortic valve thickening without causing significant narrowing and in which pathology resembles atherosclerotic coronary heart disease. We aimed to evaluate the relationship between AVS and platelet indices including mean platelet volume (MPV), platelet distribution weight (PDW), and platelet count. Method: Two hundred ten patients who were evaluated in the echocardiography unit due to various reasons between January and October 2008 were consecutively included in the study. The patients were divided into 2 groups according to presence or absence of AVS. The patient group consisted of 150 patients (76 females and 74 males; mean age, 64.5 ± 11.5 years). Patients without AVS (24 females and 36 males; mean age, 49.8 ± 15.7 years) were assigned as control group. The MPV, PDW, and platelet count were measured. Results: The MPV (9.56 ± 1.3 fL vs 9.15 ± 1.0 fL, P = .022) and PDW (16.9 ± 2.3% vs 14.9 ± 2.3, P = .001) were significantly higher in patients with AVS (+) compared to the AVS (—) group. No significant difference was demonstrated between the groups in terms of white blood cell and platelet counts (P > .05). When the AVS (+) group was compared to the AVS (—) group, a significant difference was found in respect of hypertension, diabetes mellitus, and smoking status. Conclusion: Platelet production indices including MPV and PDW were increased in patients with AVS. The complex interrelationship between increased platelet production indices and AVS and value of antithrombotic therapies in patients with AVS need to be evaluated in further studies.

A number of ninety-six hair samples from Sicilian fishermen were examined for total mercury detection by an Inductively Coupled Plasma Mass Spectrometry (ICP-MS) method. The mercury levels obtained were compared with mercury levels of 96 hair samples from a control group, in order to assess potential exposure to heavy metals of Sicilian fishermen due to fish consumption and closeness to industrial activities. Furthermore, the mercury levels obtained from hair samples were sorted by sampling area in order to verify the possible risks linked to the different locations. The overall mean concentration in the hair of the population of fishermen was6.45±7.03 μg g−1, with a highest value in a fisherman of Sciacca (16.48 μg g−1). Hair mercury concentration in fishermen group was significantly higher than in control group (p<0.01). There was no significant difference in hair total mercury concentrations between sampling areas (p>0.05). The results of this study indicate a greater risk of exposure to mercury in Sicilian fishermen, in comparison to the control population, due to the high consumption of fish and the close relationship with sources of exposure (ports, dumps, etc.).
