Differences in cadmium transport to the testis, epididymis, and brain in cadmium-sensitive and -resistant murine strains 129/J and A/J. (1/26)

Although most animals with scrotal testes are susceptible to cadmium-induced testicular toxicity, strain-related differences are seen in mice. Resistant murine strains demonstrate a decreased cadmium concentration in the testis and also in the epididymis and seminal vesicle. In this study we analyzed cadmium transport into tissues with a vascular barrier, the testis, epididymis, and brain, in an attempt to characterize the mechanisms of strain resistance to cadmium-induced testicular toxicity. In the resistant murine strain A/J, 109Cd transport (administered as 109CdCl2) was significantly attenuated in the testis, epididymis, and brain, when compared to the sensitive murine strain 129/J. The unidirectional influx constant (Ki, in microliter g-1 min-1) for 109Cd was 0.01929 in the A/J testis as compared with 1.174 in the 129/J testis (P <.0001). The percentage of a 109Cd dose that reached the A/J testis by 60 min was over 10 times less than that which reached the 129/J testis. The transport system used by cadmium in the 129/J testis was saturable, with 20 microM unlabeled cadmium chloride inhibiting transport by over 60%. The transporter was competitively inhibited by zinc (P =. 00017), but not by calcium, indicating a specificity in ion transport. Studies with isolated tubules and analysis of testicular fluid compartments demonstrated no significant difference in cadmium uptake or efflux between the strains when corrected for the amount of 109Cd entering the testis. Therefore, murine strain differences in testicular sensitivity to cadmium appear to be related to the variable presence of a transport system for cadmium in the testicular vasculature.  (+info)

Calculating bone-lead measurement variance. (2/26)

The technique of (109)Cd-based X-ray fluorescence (XRF) measurements of lead in bone is well established. A paper by some XRF researchers [Gordon CL, et al. The Reproducibility of (109)Cd-based X-ray Fluorescence Measurements of Bone Lead. Environ Health Perspect 102:690-694 (1994)] presented the currently practiced method for calculating the variance of an in vivo measurement once a calibration line has been established. This paper corrects typographical errors in the method published by those authors; presents a crude estimate of the measurement error that can be acquired without computational peak fitting programs; and draws attention to the measurement error attributable to covariance, an important feature in the construct of the currently accepted method that is flawed under certain circumstances.  (+info)

109Cd K x ray fluorescence measurements of tibial lead content in young adults exposed to lead in early childhood. (3/26)

OBJECTIVES: Tibia lead measurements were performed in a population of 19-29 year old people who had been highly exposed to lead in childhood to find whether lead had persisted in the bone matrix until adulthood. METHODS: (109)Cd K x ray fluorescence was used to measure the tibia lead concentrations of 262 exposed subjects and 268 age and sex matched controls. Questionnaire data allowed a years of residence index to be calculated for exposed subjects. A cumulative blood lead index was calculated from the time weighted integration of available data of blood lead. RESULTS: The mean (SEM) difference between exposed and control men was 4.51 (0.35) micrograms Pb/g bone mineral, and between exposed and control women was 3.94 (0. 61) micrograms Pb/g bone mineral. Grouped mean bone lead concentrations of exposed subjects were predicted best by age. When exposed and control subjects' data were combined, grouped mean bone lead concentrations were predicted best by cumulative blood lead index. The years of residence index was neither a good predictor of bone lead concentrations for exposed subjects nor for exposed and control subjects combined. Finally, exposed subjects had increased current blood lead concentrations that correlated significantly with bone lead values. CONCLUSION: Bone lead concentrations of exposed subjects were significantly increased compared with those of control subjects. Lead from exposure in early childhood had persisted in the bone matrix until adulthood. Exposed subjects had increased blood lead concentrations compared with controls. Some of this exposure could be related to ongoing exposure. However, some of the increase in blood lead concentration in adult exposed subjects seemed to be a result of endogenous exposure from increased bone lead stores. The endogenous exposure relation found for men was consistent with reported data, but the relation found for women was significantly lower. Further research is needed to find whether the observed differences are due to sex, or pregnancy and lactation.  (+info)

Remobilization of cadmium in maturing shoots of near isogenic lines of durum wheat that differ in grain cadmium accumulation. (4/26)

Cadmium accumulation in grain of durum wheat (Triticum turgidum L. var. durum) represents a concern to consumers. In an effort to understand the regulation of Cd accumulation in maturing grain, the remobilization of 109Cd applied to stem and flag leaves was examined in two near-isogenic lines that differ in grain Cd accumulation. Absorbed 109Cd was primarily retained in the labelling flap (50-54% and 65-80% for stem and flag leaves, respectively). Cadmium exported from the stem flap initially (3 d) accumulated in the stem in a declining gradient towards the head. Subsequent remobilization of Cd deposited in the stem was associated with Cd accumulation in the grain. Cadmium exported from the flag leaf flap was primarily directed to the grain. Little (<1%) Cd accumulated in the glumes or rachis, and transport of Cd to shoot tissues below the flag leaf node was low (<1%). On average, 9% and 17% of absorbed 109Cd accumulated in the grain 14 d after labelling the stem and flag leaf, respectively. Irrespective of labelling position, the low Cd-accumulating isoline averaged 1.5-2-fold lower Cd accumulation per grain and Cd concentration in the grain than the high Cd-accumulating isoline. Cadmium accumulation in the grain was inversely correlated with Cd retention in the stem (stem labelled) and labelling flap (flag leaf labelled) for both isolines. Cadmium translocation to the grain was not inhibited by Zn when both were applied simultaneously (50 pM 109Cd; 0.5 microM 65Zn) to the flag leaf. These results show that elevated remobilization of Cd from the leaves and stem to the maturing grain may be partially responsible for the high accumulation of Cd in durum wheat grain.  (+info)

Influence of prior Cd(2+) exposure on the uptake of Cd(2+) and other elements in the phytochelatin-deficient mutant, cad1-3, of Arabidopsis thaliana. (5/26)

In order to test the potential effect of prior exposure to different Cd concentrations on Cd uptake and accumulation, plants of Arabidopsis thaliana, including a phytochelatin-deficient mutant, cad1-3, and the wild type, were compared. For Cd uptake experiments, plants were grown for 1 week in nutrient solution containing different Cd concentrations (0, 0.05, 0.1, 0.25, 0.5, and 1.0 microM Cd(NO(3))(2)). Thereafter they were subjected to 0.5 microM Cd labelled with (109)Cd for 2 h. Uptake experiments with (109)Cd showed that the phytochelatin-deficient mutant cad1-3, accumulated less Cd than the wild type. Both a lower proportion and lower total amount of absorbed Cd were translocated to the shoot in cad1-3 plants compared to wild-type plants. Cadmium exposure also influenced the amounts of nutrients found, whereby after exposure to high Cd concentrations (0.5, 1.0 microM) during growth, cad1-3 roots contained less Fe, K, Mg, P, and S compared to roots of the wild type. In cad1-3 these elements decreased with increasing Cd concentration. The total Cd content in roots and shoots increased significantly with increasing Cd concentration during growth, although the increase was much less in cad1-3 plants. In time-dependent experiments of Cd uptake carried out between 15 and 120 min on plants not previously exposed to Cd, no significant difference in Cd accumulation between the mutant and wild type were found, although a smaller amount of Cd was translocated to the shoot in cad1-3 plants. The possibility that the differences in Cd accumulation in mutant and wild-type lines may be due to the cytosolic Cd regulation, which is inhibited by the complexation of Cd by phytochelatins, is discussed.  (+info)

Characteristics of cadmium uptake in two contrasting ecotypes of the hyperaccumulator Thlaspi caerulescens. (6/26)

Uptake of Cd and Zn by intact seedlings of two contrasting ecotypes of the hyperaccumulator Thlaspi caerulescens was characterized using radioactive tracers. Uptake of Cd and Zn at 2 degrees C was assumed to represent mainly apoplastic binding in the roots, whereas the difference in uptake between 22 degrees C and 2 degrees C represented metabolically dependent influx. There was no significant difference between the two ecotypes in the apoplastic binding of Cd or Zn. Metabolically dependent uptake of Cd was 4.5-fold higher in the high Cd-accumulating ecotype, Ganges, than in the low Cd-accumulating ecotype, Prayon. By contrast, there was only a 1.5-fold difference in the Zn uptake between the two ecotypes. For the Ganges ecotype, Cd uptake could be described by Michaelis-Menten kinetics with a V(max) of 143 nmol g(-1) root FW h(-1) and a K(m) of 0.45 microM. Uptake of Cd by the Ganges ecotype was not inhibited by La, Zn, Cu, Co, Mn, Ni or Fe(II), and neither by increasing the Ca concentration. By contrast, addition of La, Zn or Mn, or increasing the Ca concentration in the uptake solution decreased Cd uptake by Prayon. Uptake of Ca was larger in Prayon than in Ganges. The results suggest that Cd uptake by the low Cd-accumulating ecotype (Prayon) may be mediated partly via Ca channels or transporters for Zn and Mn. By contrast, there may exist a highly selective Cd transport system in the root cell membranes of the high Cd-accumulating ecotype (Ganges) of T. caerulescens.  (+info)

Influence of iron status on cadmium and zinc uptake by different ecotypes of the hyperaccumulator Thlaspi caerulescens. (7/26)

We have previously identified an ecotype of the hyperaccumulator Thlaspi caerulescens (Ganges), which is far superior to other ecotypes (including Prayon) in Cd uptake. In this study, we investigated the effect of Fe status on the uptake of Cd and Zn in the Ganges and Prayon ecotypes, and the kinetics of Cd and Zn influx using radioisotopes. Furthermore, the T. caerulescens ZIP (Zn-regulated transporter/Fe-regulated transporter-like protein) genes TcZNT1-G and TcIRT1-G were cloned from the Ganges ecotype and their expression under Fe-sufficient and -deficient conditions was analyzed. Both short- and long-term studies revealed that Cd uptake was significantly enhanced by Fe deficiency only in the Ganges ecotype. The concentration-dependent kinetics of Cd influx showed that the V(max) of Cd was 3 times greater in Fe-deficient Ganges plants compared with Fe-sufficient plants. In Prayon, Fe deficiency did not induce a significant increase in V(max) for Cd. Zn uptake was not influenced by the Fe status of the plants in either of the ecotypes. These results are in agreement with the gene expression study. The abundance of ZNT1-G mRNA was similar between the Fe treatments and between the two ecotypes. In contrast, abundance of the TcIRT1-G mRNA was greatly increased only in Ganges root tissue under Fe-deficient conditions. The present results indicate that the stimulatory effect of Fe deficiency on Cd uptake in Ganges may be related to an up-regulation in the expression of genes encoding for Fe(2+) uptake, possibly TcIRT1-G.  (+info)

Cadmium-metallothionein interactions in the olfactory pathways of rats and pikes. (8/26)

Deposition of cadmium onto the olfactory epithelium results in transport of the metal along the primary olfactory neurons to the olfactory bulbs of the brain. The present investigation was undertaken to determine the intracellular ligand binding of cadmium during this process. (109)Cd(2+) was applied on the olfactory epithelium of rats and pikes, and the subcellular distribution of the metal in the olfactory pathways was then examined. Two groups of rats were used: one pretreated with intranasal instillations of nonlabeled cadmium and the other given physiological saline (controls). Cellular fractionations showed that the (109)Cd(2+) was predominantly present in the cytosol of all samples, both in the rats and the pikes. Gel filtrations of the olfactory epithelium of control rats killed 2 h after the (109)Cd(2+) instillation showed that the metal was recovered in two peaks with elution volumes corresponding to metallothionein (MT) and glutathione (GSH)-the latter peak being the predominant one. However, in the epithelium of the cadmium-pretreated rats killed at 2 h, (109)Cd(2+) was recovered in one peak corresponding to MT. In the olfactory epithelium and bulbs of both groups of rats killed at 48 h, as well as in the olfactory epithelium, nerves, and bulbs of pikes killed at this interval, (109)Cd(2+) was recovered in one peak corresponding to MT. Immunohistochemistry of the olfactory system of rats given cadmium in the right nasal cavity showed induction of MT in the neuronal, sustentacular, and basal cells of the right olfactory epithelium, in the nerve fascicles in the lamina propria of the right olfactory mucosa, and in the olfactory nerve layer of the right olfactory bulb. On the left side, the immunoreactivity was low in these structures. MT immunoreactivity was observed in the glomeruli of both the right and the left olfactory bulbs. However, the staining was homogeneously distributed within the entire glomeruli of the right bulb, whereas it showed a mesh-like pattern corresponding to the localization of astrocytes in the glomeruli of the left bulb. We conclude that exposure of the olfactory epithelium to cadmium results in induction of MT in the primary olfactory neurons and a transport of the metal in these neurons as a cadmium-metallothionein (CdMT) complex. Our results further indicate that GSH is a ligand that can interact with cadmium before the metal binds to MT.  (+info)

Breadsticks are pencil-sized sticks of dry bread widely consumed as a pre-meal appetiser. They are basically wheat-based snacks, which makes them a good matrix to evaluate mycotoxin contamination, since wheat is very susceptible to fungal attack. In this sense, the fast, selective and sensitive gas chromatography-triple quadrupole tandem mass spectrometry (GCQqQ- MS/MS) method proposed here allows simultaneous determination of deoxynivalenol (DON), 3-acetyldeoxynivalenol, fusarenon-X, diacetoxyscirpenol, nivalenol, neosolaniol, HT-2 and T-2 toxin in breadsticks after QuEChERS extraction and clean-up. The performance of the method was assessed with respect to European Commission Regulations by studying the selectivity and specificity, limit of detection (LOD), limit of quantitation (LOQ), linearity, matrix effect, accuracy, precision and trueness. Satisfactory results in terms of validation parameters were obtained for all selected mycotoxins (recovery range of 70,br,110%, RSD , 10%, LOQ ,40 μg ...
Deoxynivalenol (DON) is the most frequently detected mycotoxin in cereal and cereal-based products, and a continuous monitoring of this toxin in foodstuffs is highly desirable. In this sense,a QuEChERS based extraction and gas chromatography-tandem mass spectrometry detection is proposed to determine DON in an appetizer largely consumed, the wheat-based snacks. In this study, a total of 40 samples were analyzed. The samples were divided into two groups based on the composition. Extraction was carried out with acetonitrile followed by a dispersive solid phase extraction and analyzed for DON content by gas chromatography-tandem mass spectrometry (GC-QqQ-MS/MS) method. The overall occurrence of samples with DON was 67.5%, with maximum content of 61μg/kg. In spite of its high incidence, DON concentrations found in samples were much lower than the maximum limit established in the current European legislation (500 μg/kg) for the foodstuff evaluated. Data obtained indicated a low exposure to DON ...
IFN-gamma plays an important role in host defense against microbial disease. Here, we studied the role of IFN-gamma in lethal and nonlethal murine malaria. Administration of recombinant murine IFN-gamma resulted in a dose-dependent protection of SW, BALB/cByJ, and CBA/J mice from the lethal variant of Plasmodium yoelii 17x (PyL) but had little effect on the course of the nonlethal variant of this parasite (PyNL). Administration of recombinant IFN-gamma also resulted in the activation of peritoneal macrophages for increased phagocytosis of malaria-infected erythrocytes and release of H2O2, as measured in vitro. The ability of spleen cells from infected mice to produce endogenous IFN-gamma and release H2O2 during the course of malaria was also studied. In BALB/cByJ mice, which are relatively susceptible to PyL and PyNL, there was an initial burst of IFN-gamma only in response to PyNL whereas in CBA/J mice, which are relatively resistant to these parasites, there was an initial burst of IFN-gamma ...

The study compares the impact due to rice stem borers in two sites (Yaoundé and Ntui). It also shows the diversity of the African Rice Gall Midge (AfRGM) biotypes in southern Cameroon (Santchou, Ndop, Tonga, Ebolowa, Ba?gom, Yaoundé and Ntui). The New Rice for Africa (NERICA) varieties 3, 8, 9 and 13 sown in Ntui were less attacked than those sown in Yaoundé. At both sites, damages ranged from 0.78% to 2.7%. In terms of diversity, the main stem-borer species were O. oryzivora, Diopsis apicalis, D. longiconis and Chilo zacconius. Molecular analyses of Orseolia oryzivora larvae collected in the localities of Santchou, Ndop, Tonga, Ebolowa, Ba?gom and Yaoundé showed the existence of more than one O. oryzivora biotype in southern Cameroons rice basins.

According to early studies on the transport of cadmium (Cd), it was suggested that iron (Fe) or calcium (Ca) transport system is important in Cd incorporation into cells based on the evidence that dietary Fe or Ca deficiency enhanced intestinal Cd absorption. Transporter of Fe, divalent metal transporter, was shown to be capable of permeating other divalent metals including Cd. On the other hand, L-type Ca channel was also shown to be responsible at least in part, for cellular Cd uptake. In addition to Ca and Fe, it was suggested that the transporter for cellular incorporation of manganese (Mn) and zinc (Zn) may also be involved in Cd uptake by using Cd-resistant metallothionein null cells. Recently, two members of ZIP family, ZIP8 (Slc39a8) and ZIP14 (Slc39a14) have been suggested as the candidates for Cd transporter. ZIP8 was found to be the determinant for the sensitivity to Cd-induced testicular hemorrhage. ZIP14 was down-regulated in Cd-resistant metallothionein null cells. Further ...

Our results suggest that functional actin is needed during SC differentiation not only for changes in cell shape but also for abundant expression of myelin-specific mRNAs. The initial step in morphological differentiation, elongation, was inhibited only when higher CD concentrations (0.75-1.0 μg/ml) known to remove stress fibers in other cell types were used (Yahara et al., 1982). At lower CD concentrations (0.25 μg/ml), SC elongation and segregation of axons away from each other occurred, but ensheathment of axons in a 1:1 relationship and spiralization did not occur. Phalloidin staining of CD-treated cultures revealed that actin became increasingly disrupted and aggregated as CD concentration increased. At the time experiments began, all cultures had equal SC densities and SCs displayed a rounded morphology characteristic of their behavior in ascorbate-free medium, which allows SC proliferation but not differentiation (Eldridge et al., 1987; Fernandez-Valle et al., 1993). Therefore, any ...

Recently, there has been considerable interest in the use of terrestrial plants as a green technology for the remediation of surface soils contaminated with toxic heavy metals. This technology, termed phytoremediation, uses plants to extract heavy metals from the soil and to concentrate them in the harvestable shoot tissue (1, 2). A major factor behind the interest in phytoremediation of metal-polluted soils has been the growing awareness of the existence of a number of metal-accumulating plant species. These plant species, called hyperaccumulators, are endemic to metalliferous soils and can accumulate and tolerate high levels of heavy metals in the shoot (3, 4). Among the best known hyperaccumulators is Thlaspi caerulescens. This member of the Brassicaceae family has attracted the interest of plant biologists for over a century because of its ability to colonize calamine and serpentine soils containing naturally elevated levels of heavy metals such as Zn, Pb, Cd, Ni, Cr, and Co. Certain ...
Hyperaccumulator plants are able to accumulate unusually high levels of heavy metals because they can store them in cell vacuoles where they cannot harm metabolic processes in the cell cytoplasm. The plant cell vacuole has been termed the cellular trashbag. One yeast that accumulates high levels of cadmium has small peptides called phytochelatins that bond with cadmium ions. This allows transport of the cadmium ions across cell membranes and into the vacuole.

An intravascular catheter system and method of manufacture for implanting a radially expandable stent within a body vessel. The catheter system includes a shaft defining an inflation lumen in fluid communication with a balloon on the distal end of the shaft. A stent is mounted coaxially upon a balloon. The balloon has ridges impressed in the outline of the stent for at least a portion of the stent. The ridges are sized to receive the stent so as to cause the balloon to expand evenly and the stent to deploy uniformly. In an alternative embodiment the balloon may additionally have a polymeric surface layer exhibiting a higher coefficient of friction than the underlying material against the stent material. The surface layer may be provided as a high friction polymeric coating on a formed balloon or as a coaxial extrusion of a high friction polymeric material over the underlying balloon tubing material. In a further embodiment the balloon may have the polymeric surface layer exhibiting a higher coefficient

In mechanically ventilated preterm infants with respiratory distress syndrome (RDS), exogenous surfactant application has been demonstrated both to decrease DNA-synthesis but also and paradoxically to increase epithelial cell proliferation. However, the effect of exogenous surfactant has not been studied directly on alveolar type II cells (ATII cells), a key cell type responsible for alveolar function and repair. The aim of this study was to investigate the effects of two commercially available surfactant preparations on ATII cell viability and DNA synthesis. Curosurf® and Alveofact® were applied to two ATII cell lines (human A549 and mouse iMATII cells) and to primary rat ATII cells for periods of up to 24 h. Cell viability was measured using the redox indicator resazurin and DNA synthesis was measured using BrdU incorporation. Curosurf® resulted in slightly decreased cell viability in all cell culture models. However, DNA synthesis was increased in A549 and rat ATII cells but decreased in iMATII
Data from a survey of Western Australian grain growers are used to characterise the use and perceptions of durum wheat. The main objective was to identify opportunities for extension to increase the level of durum wheat adoption throughout the grain growing regions of WA. Perceptions of durum wheat characteristics were elicited along with other variables used to model the economic value of durum wheat in the local cropping system. Logistic regression analysis found that perceptions of the yield potential were most influential, with almost half of respondents believing current durum wheat varieties were unsuitable for Western Australian conditions. Perceptions of durum rust resistance were also significant in the adoption decision. Informational variables were shown to be of influence; however, critically, past use was not a significant predictor of future use. Before broad extension and promotion of the trialing of durum can be successful, efforts in Western Australia will need to focus on research to
The proposed research integrates molecular, biochemical, and whole-plant approaches to better characterize the network of wheat genes actively involved in wheat root response to N and Cd. Based on ongoing field studies, two pairs of winter wheat genotypes will be selected: 1) one pair that differs for NUE; 2) one pair that differs for grain Cd accumulation. The differential gene expression in roots of these pairs of genotypes in response to N limitation or Cd supplementation, respectively, in hydroponic conditions will be measured. IV.c.1. Project details/sequence Phase I: Determine appropriate level of N limitation and Cd supplementation in hydroponically grown plants. A range of N concentrations will be applied to the NUE+ and NUE- genotypes with the objective of identifying a minimum stress condition. Similarly, to determine a sub-toxic level of Cd, a range of Cd concentrations will be applied to the Cd+ and Cd- genotypes. A follow-up experiment will integrate the four winter wheat genotypes ...
The expression of delayed-type hypersensitivity in animals has been inhibited by a variety of anticoagulants, but direct evidence for activation of clotting in the evolution of these reactions has been lacking. Using the fluorescent antibody technique we here demonstrate that fibrin deposition is a prominent and consistent feature of both allergic contact dermatitis and classic delayed hypersensitivity skin reactions in man. Fib was detected in 55 of 58 delayed reactions studied at the peak of their intensity. The characteristic distribution of Fib-principally in the intervascular portions of the reticular dermis with sparing of vessels and their associated cuffs of mononuclear cells-is unusual and quite different from that described in antibody-mediated lesions in animals or man. Fib was found in vessel walls in only 2 of 94 biopsies studied. With a single exception, deposition of immunoglobulins and complement was not observed.. The pathogensis and significance of Fib deposition in these ...
Thlaspi caerulescens (formerly known as Thlaspi alpestre, until that name was shown to be illegitimate) is a plant with a puzzling distribution. In the UK it occurs in a few widely separated upland localities from Mendip to Rhum. In most cases (but not all) its associated with high levels of heavy metal pollution; for example, lead or zinc spoil-heaps. How a plant with such apparently limited seed-dispersal techniques ever arrived in these remote places is a mystery. Anyway, its generally supposed to be native. Elsewhere the main native populations are in mountainous central Europe: - the Alps and Carpathians. In Scandinavia its history is totally different. Here its accepted as an introduced plant, first noticed in 1840. It has since spread widely and now grows all over Scandinavia in all sorts of environments (e.g. here on a calcareous slope in open woodland). The contrast between the unfussy vigorously-spreading alien population in Sweden and the tiny, vulnerable pockets in the UK could ...

Rishikesh and Shimla are both very interesting places to visit - apart from the trek angle. Rishikesh is said to be the yoga capital of the world, with almost every third or fourth place a yoga centre of sorts - but its also a great place to relax and contemplate, especially a bit higher up on the hills, with a view to the Ganges, and a great place for rafting too. Shimla is the quintessential colonial relic in Northern India, though a bit crowded these days, and a nice town to base oneself in for exploring the region..
