This study investigated how the stock structure of Arripis trutta is influenced by the movement of adult fish. Five-year-old fish were sampled from four regions in south-east Australia encompassing ~1500km of coastline. Transverse otolith sections were analysed using laser-ablation inductively coupled plasma-mass spectrometry, providing age-related elemental profiles. Multivariate analyses showed that for most age groups, the elemental fingerprint of northern New South Wales (NSW) fish was significantly different from those of the other locations. Northern NSW fish also had a different fingerprint from those of all other locations for the first part of the fish’s life. These results indicate that most A. trutta originate in southern NSW, Victoria and Tasmania and move progressively northward with increasing age. Some recruitment occurs in northern NSW but these fish may not mix with immigrants from further south until they are more than 5 years old. When assessed with the strong latitudinal age gradient of the population, these data are consistent with a single, panmictic stock. The data also highlight the utility of otolith transect analysis in understanding the influence of age-related movements on stock structure and appropriate spatial management of exploited fish species.

Plasma Mass Spectrometry

The present study investigated the stock structure of snapper (Pagrus auratus) in South Australia, and the extent to which this is influenced by adult movement. Fish from the 9+ age class were sampled from six different regions, encompassing >2000 km of coastline and different habitat types. The chemistry of transverse sections of otoliths was sampled using laser ablation inductively coupled plasma-mass spectrometry, providing elemental profiles that were related to age for the first nine years of the fish’s lives. The age-related annual averages for both 88Sr and 138Ba differed significantly between regions. They were, however, similar for the first three years, then diverged considerably between the ages of three to five years, and then remained consistently different through to the age of nine years. This suggests that all fish, regardless of where captured, originated from only one or two nursery areas, but dispersed throughout the different regions between the ages of three to five years, before becoming resident to their new regions of occupancy. Thus, this population of snapper represents a single, large, stock where the individuals have a common origin, but through age-related emigration ultimately disperse and supplement the low abundance populations in regional State waters.

Abstract Detailed cathodoluminescence (CL) imaging of zircon crystals, coupled with Laser Ablation Multi-Collector Inductively Coupled Plasma Mass Spectrometry (LA-MC-ICP-MS) U-Pb zircon dating was used to develop new insights into the evolution of granitoids from the High Tatra Mountains. The zircon U-Pb results show two distinct age groups (350±5 Ma and 337±6 Ma) recorded from cores and rims domains, respectively. Obtained results point that the last magmatic activity in the Tatra granitoid intrusion occurred at ca. 330 Ma. The previously suggested age of 314 Ma reflects rather the hydrothermal activity and Pb-loss, coupled with post-magmatic shearing.

The Difference

Soil testing for plant-available phosphorus (P) in Australia is most commonly conducted using alkaline sodium bicarbonate extraction (Olsen or Colwell tests), followed by a colourimetric assay to measure the concentration of P in solution. Analysis by inductively coupled plasma (ICP) spectroscopy has become increasingly popular internationally for other soil P tests, especially Mehlich 3, due to its efficiency and ability to measure multiple elements in the one extract. The use of ICP in place of colourimetry has been used in some Australian laboratories for bicarbonate-extractable P. However, the method is known to measure forms of P (organic) that are not measured by the colourimetric assay. This study presents data comparing soil Colwell P measured by the 2 methods for 714 soil samples from pastoral sites in south-east New South Wales. Measurement by ICP consistently yielded significantly higher P concentrations than the colourimetric method (ICP-P = 1.122Col-P + 57.0, r2 = 0.95, P < 0.001). Differences between the 2 techniques were more marked in 0–20 mm than 0–100 mm depth soil samples, and in soils with greater clay contents, suggesting that the difference was related to soil organic matter, and thereby organic P contents. Relative differences were greatest in soils with lower P concentrations, i.e. within the agronomic optimum range of most interest to farmers. ICP analysis cannot be directly correlated with colourimetrically measured P in bicarbonate extracts, and would need to be developed and calibrated as a separate, new soil P test.

Noradrenaline Levels

AbstractPlasma noradrenaline levels increase with aging, and this could contribute to the sympathetic overactivity that is associated with essential hypertension and the metabolic syndrome. The underlying cause of this rise in noradrenaline is unknown, but a clue may be that mercury increases noradrenaline output from the adrenal medulla of experimental animals. We therefore determined the proportion of people from 2 to 104 years of age who had mercury in their adrenal medulla. Mercury was detected in paraffin sections of autopsied adrenal glands using two methods of elemental bioimaging, autometallography and laser ablation-inductively coupled plasma-mass spectrometry. Mercury first appeared in cells of the adrenal medulla in the 21–40 years group, where it was present in 52% of samples, and increased progressively in frequency in older age groups, until it was detected in 90% of samples from people aged over 80 years. In conclusion, the proportion of people having mercury in their adrenal medulla increases with aging. Mercury could alter the metabolism of catecholamines in the adrenal medulla that leads to the raised levels of plasma noradrenaline in aging. This retrospective autopsy study was not able to provide a definitive link between adrenal mercury, noradrenaline levels and hypertension, but future functional human and experimental studies could provide further evidence for these associations.

Context.— Recently, an exchangeable copper (CuEXC) assay has been suggested as a robust and feasible diagnostic tool for Wilson disease (WD). Although WD is a disorder that requires lifelong treatment and monitoring, few data are currently available regarding the status of copper levels in children. Objective.— To evaluate the performance of copper assays and establish a reference interval for total copper and CuEXC in the pediatric population. Design.— Serum samples from children aged 1–5 (n = 122), 6–12 (n = 125), and 13–18 years (n = 120) were analyzed. Total copper and CuEXC concentrations were directly measured using inductively coupled plasma mass spectrometry, and relative CuEXC levels were calculated. Total copper reference intervals, CuEXC levels, and relative CuEXC levels were determined based on the 2.5th and 97.5th percentiles of the data with 90% confidence intervals. Results.— There were significant differences in the median concentrations of total copper and relative CuEXC among the age groups. Reference intervals determined for total copper were 82 to 167, 75 to 139, and 64 to 133 μg/dL for children aged 1 to 5, 6 to 12, and 13 to 18 years, respectively. The reference intervals for CuEXC were 4.29 to 9.79, 4.02 to 9.09, and 3.55 to 8.25 μg/dL for children aged 1 to 5, 6 to 12, and 13 to 18 years, respectively. Among 11 patients with suspected WD, relative CuEXC values were elevated in all 3 diagnosed with WD. Conclusions.— The pediatric reference intervals derived in this study are expected to be useful for the diagnosis, differential diagnosis, treatment, and monitoring of pediatric patients with WD.

Abstract Background Minerals play an important role in children’s growth and cognition. In this study, our aim was to establish reference intervals of mineral level in Children of Liaoning province (China) and provide a reliable basis for future preventive healthcare guidelines. Methods Random samples of 2217 healthy children aged 0–15 years who were referred for routine hospital laboratory examinations in the cities of Shenyang, Fushun, Fuxin, Benxi, Chaoyang and Lingyuan were invited to participate in the study. Serum levels of Calcium (Ca), Iron (Fe), Zinc (Zn), Magnesium (Mg), Copper (Cu), Manganese (Mn), Selenium (Se), Mercury (Hg), Nickel (Ni), Cobalt (Co), and Lithium (Li) were determined by inductively coupled plasma mass spectrometer(ICP-MS). Results Sex-related significant differences in the serum concentrations of the Mg and Cu (P < 0.05). Age-related significant differences were found in serum levels of Ca, Fe, Zn, Mg, Cu and Mn (P < 0.05) and the concentrations of 9 minerals (Ca, Mg, Cu, Mn,Se,Hg,Ni,Co and Li in serum varied from season to season (P < 0.05). The Spearman correlation matrix of 11 minerals was shown as a heat map, the correlations between Ca-Zn, Ca-Mg, Fe-Zn, Fe-Se, Mn-Ni, Se-Hg, Se-Ni, Hg-Ni, and Ni-Co, Ni-Li were the strongest compared with others. Conclusions The reference intervals of serum 11 minerals for children should considering the sex, age and season, which may be useful for decisive diagnoses of abnormality of the 11minerals and the related diseases.

<p><strong>Background:</strong> Cosmetics' use is very popular all over the world and in some parts of Arabian countries. The use of some cosmetics as Kohl is part of culture and traditions, and is used since very young ages. This makes detection of heavy metal content in cosmetics marketed in Egypt and other Arabian markets of crucial importance.</p><p><strong>Objective:</strong> To evaluate the levels of heavy metals content among different cosmetic products in the Arabian market.</p><p><strong>Methods:</strong> Different brands of; anti-freckle creams, eye shadows, eyeliners, facial powders, foundation, henna and lipsticks were purchased from open markets in Egypt and Saudi Arabia. Sample preparation and analysis was conducted, to estimate levels of twelve different metals (Pb, As, Cd, Ag, Ba, Al, Cr, Mn, Co, Ni, Cu, and Zn) using Inductively Coupled Plasma Mass Spectrometry (ICP-MS).</p><p>Results: The mean concentration of some studied metals as Aluminium, lead, arsenic, copper and nickel were higher than permissible levels for cosmetics in some of the studied samples. Para- Phenylenediamine (PPD) was detected in all the studied 7 Henna samples.</p><p><strong>Conclusion:</strong> In conclusion, cosmetic contamination with metals above permissible levels is very common in most of the products available in the developing world and Arabian markets. Physicians and users must be aware of the probable toxicity of these elements and of the clinical signs of systemic poisoning. Considering popular use of cosmetics by different age groups, the hazardous cumulative effects of prolonged exposure to low concentrations of metals like; Aluminium, lead, Arsenic, nickel and copper especially in children, cannot be ruled out. Further studies are recommended in addition, cosmetic market control and legislation procedures should be thoroughly implemented.</p>
