Analytical characterization of trace elements (zinc, copper, cadmium, lead and selenium) in saliva of pigs under common ...
Published in BMC Veterinary Research
BackgroundThis study is focused on the measurement of trace elements (zinc, copper, cadmium, lead and selenium) in the saliva of pigs in order to study their levels on different porcine pathological conditions in the field. The experiment involved 15 pigs without clinical signs of disease and 42 diseased pigs (suffering from lameness, rectal prolap...
Det svenska nationella miljöövervakningsprogrammet för miljögifter i marin biota (fram till 2018 års data) : - Temporal-...
The report summarises the monitoring activities within the National Swedish Contaminant Programme in marine biota. Few trends are found for the biological variables of the biota included in the programme (age, weight, length, and fulton´s condition factor). This is expected, as samples are selectively selected to avoid trends. However, all variable...
Bioaccumulation and physiological responses of the Coontail, Ceratophyllum demersum exposed to copper, zinc and in combi...
Published in Ecotoxicology and environmental safety
Ceratophyllum demersum is a submerged aquatic angiosperm which is fast growing in contaminated water. This plant has no roots and so takes up nutrients from the water column without the complicating factor of differential shoot/root uptake of nutrients. This study aimed to compare the bioaccumulative capacities of Cu, Zn and their combination by C....
Life-time exposure to waterborne copper IV: Sperm quality parameters are negatively affected in the killifish Poecilia v...
Published in Chemosphere
In previous studies, we have shown that copper (Cu) is significantly accumulated in various tissues of killifish Poecilia vivipara following chronic exposure. Also, we showed that chronic metal exposure disrupted energy production and growth in this species. In the present study, we aimed to evaluate if chronic exposure to this metal could also aff...
Effect of a Shift in Diurnal Geomagnetic Variation on the Activity and Sensitivity of Digestive Glycosidases in Roach Un...
Published in Izvestiya, Atmospheric and Oceanic Physics
Abstract—The effect of temporal shifts in diurnal geomagnetic variation with 6- and 12-h intervals relative to the day–night cycle on the activity of digestive glycosidases (maltase and amylolytic activity) and their sensitivity to the in vitro influence of heavy metal ions (Cu2+, Zn2+, Pb2+, Cd2+) at a concentration of 25 mg/L has been studied in ...
The role of copper and zinc accumulation in defense against bacterial pathogen in the fujian oyster (Crassostrea angulat...
Published in Fish & shellfish immunology
Cu and Zn are hyper-accumulated in oysters, and the accumulation of these metals increases host resistance to pathogens. However, the role of Cu/Zn in oyster immune defense remains unclear. In this study, Crassostrea angulata with different levels of Cu and Zn were obtained through metal exposure or selective breeding. Both in vivo and in vitro exp...
Controlling Contact Configuration of Carboxylic Acid-Based Molecular Junctions Through Side Group
...Published in Nanoscale Research Letters
In this paper, the contact configuration of single molecular junction is controlled through side group, which is explored by electrochemical jump-to-contact STM break junction. The conductance values of 2-methoxy-1,3-benzenedicarboxylic acid (2-M-1,3-BDC) is around 10–3.65 G0, which is different from that of 5-methoxy-1,3-benzenedicarboxylic acid (...
Cu/[email protected] Hollow Nanofiber Gas Sensor: Effect of Hollow Nanofiber Structure and P–N Junction on Operating Temperature a...
For the fast and easy detection of carbon monoxide (CO) gas, it was necessary to develop a CO gas sensor to operate in low temperatures. Herein, a novel Cu/CuO-decorated ZnO hollow nanofiber was prepared with the electrospinning, calcination, and photodeposition methods. In the presence of 100 ppm CO gas, the Cu/CuO-photodeposited ZnO hollow nanofi...
The Change of Metallothionein and Oxidative Response in Gills of the Oreochromis niloticus after Exposure to Copper
In the present study, we investigated the effects of waterborne copper (Cu) on the levels of metallothionein (MT) and malondialdehyde (MDA), as well as activities of superoxide dismutase (SOD) and catalase (CAT) in gills of cichlid fish Oreochromis niloticus. The Cu concentrations in gills were measured using an atomic absorption spectrometer. The ...
