Rapid analysis of trans,trans-muconic acid in urine using microextraction by packed sorbent
Springer Science and Business Media LLC - Tập 9 - Trang 317-324 - 2018
A simple and fast method has been developed for the determination of urinary trans,trans-muconic acid (ttMA) based on micro-extraction by packed sorbent (MEPS), followed by HPLC-UV detection. Parameters affecting the performance of MEPS were investigated. The results of the MEPS-HPLC-UV procedure were compared with the results of the conventional SPE method. The procedure was used for the determin...... hiện toàn bộ
The trend of risk assessment technologies of animal Environmental Risk Substances
Springer Science and Business Media LLC - Tập 6 - Trang 233-237 - 2015
Numerous types of Environmental Risk Substances (ERSs) are produced, causing exposure not only in the industry, but also in daily life in modern society. ERSs are pernicious to animals as well as to human beings, since some of them remain for long periods of time or become condensed in organisms during the ecological cycles via environmental pollution. In recent times, the quality and distribution...... hiện toàn bộ

Effects of long-term diazinon exposure on some immunological and haematological parameters in rainbow trout Oncorhynchus mykiss (Walbaum, 1792)
Springer Science and Business Media LLC - Tập 6 - Trang 1-7 - 2014
Metagenome analysis was used to monitor changes in microbial population during the industrial-scale batch fermentation period (0, 15 days and 2 years). Genomic DNA was extracted from Bachu-Kimchi samples and was sequenced using GS Junior Titanium system, which yielded a total 6886, 6271, and 6621 reads from 0, 15 days and 2 years samples, respectively. Phylogenetic analysis based on 16S rRNA seque...... hiện toàn bộ
Endocrine disruptive action of cypermethrin in male mice
Springer Science and Business Media LLC - Tập 3 - Trang 69-79 - 2011
Administration (intubation) of cypermethrin to adult male mice for 6 and 12 weeks on alternate day in 3 dose levels,1.38, 2.76 and 5.52 mg/kg body weight (bw) corresponding to 1/476, 1/238 and 1/119 of LD50 dose respectively, caused degeneration of germinal epithelium, vacuolization of seminiferous tubules and a significant decrease in i) weight of the body, testes and epididymis, ii) diameter of ...... hiện toàn bộ
Low-dose radiation-induced cell death in doxorubicin-sensitive leukemic K562 and resistant leukemic K562/Dox cancer cells associated with ferroptosis induction
Springer Science and Business Media LLC - Tập 15 - Trang 249-255 - 2023
It has been reported that low-dose total body irradiation techniques can be applied to blood cancers such as leukemia. The aim of this study is to investigate the effect of low-dose radiation-induced cell death via ferroptosis phenomenon in doxorubicin-sensitive leukemic K562 and resistant leukemic K562/Dox cancer cells. The cells were irradiated with X-rays at total doses of 0, 0.02, 0.05, and 0....... hiện toàn bộ
Accumulation of tributyltin and triphenyltin compounds in laboratory exposure and their induction of imposex in rock shell (Thais clavigera)
Springer Science and Business Media LLC - Tập 1 - Trang 182-187 - 2009
A laboratory exposure experiment was conducted to evaluate imposex (imposition of male sexual organ on female) induction potential of tributyltin (TBT) and triphenyltin (TPT) in rock shell,Thais clavigera. Apparent induction of imposex was observed in rock shell, exposed to TBT and TPT compound at well below 3.65 ng Sn/L respectively. Degree of imposex in female rock shell was dependent on both TB...... hiện toàn bộ
Effects of heavy metals on transcription and enzyme activity of Na+/K+-ATPase in the monogonont rotifer, Brachionus koreanus
Springer Science and Business Media LLC - Tập 8 - Trang 128-134 - 2016
Heavy metals can lead to osmotic stress by disrupting the regulation of sodium ion in aquatic organisms. In this study, gene expression patterns and enzymatic activities of Na+/K+-ATPase in the monogonont rotifer, Brachionus koreanus were measured after exposure to different Cd (7.5, 15, and 30 mg/L), and Pb (0.1, 0.5, and 1.0 mg/L), respectively. As results, a significant increase in Bk Na+/K+-AT...... hiện toàn bộ
Level of Petroleum Hydrocarbons in Water and Sediments of Ikoli Creek Bayelsa State Nigeria
Springer Science and Business Media LLC - Tập 11 - Trang 114-119 - 2019
This study investigated the level Petroleum hydrocarbon in Ikoli creek, Bayelsa state Nigeria with focus on water and sediments. Water and sediments were assessed using standard analytical procedures. Water from surface levels and sediment samples were collected from five locations in the creek. Soxhlet extraction method and liquid-liquid techniques were used in extraction of the petroleum hydroca...... hiện toàn bộ
Stress responses analysis of As(III), Cd and Pb inEscherichia coli
Springer Science and Business Media LLC - Tập 1 - Trang 192-195 - 2009
In this study, it was analyzed specific stress responses caused by heavy metals such as sodium arsenite (As(III)), cadmium nitrate (Cd) and led nitrate (Pb) using four different stress responsive genes inEscherichia coli, i.e.fabA, grpE, katG andrecA. The expression levels of these genes were quantified by semi-quantitative reverse transcription-PCR. It was found that four genes have shown differe...... hiện toàn bộ
