In a representative US population higher levels of urinary cadmium were found to be significant predictors of lower FVC, FEV1, and FEV1/FVC in current and former smokers but not in never smokers. In addition, variability in urine cadmium levels was found among current smokers. It is not clear whether this finding is related to the dose of cadmium to which smokers are exposed or to variability in the uptake and metabolism of cadmium in smokers. It is possible that the variability in cadmium levels in smokers is related to the intensity of smoking-that is, smokers with higher cadmium levels extract more tar and nicotine out of each cigarette than smokers with lower levels. It is also possible that the variability in lung function in smokers is similarly related to variability in smoking intensity, and that cadmium levels are just a long term marker of tobacco dose.. Cadmium intake in humans is either through ingestion or inhalation, with the major source of exposure in never smokers being ...
Blood and urinary cadmium concentrations together with cadmium in air concentrations from the breathing zone of 18 male workers in an alkaline battery factory were determined at regular intervals for 11 consecutive weeks. Nine of the workers examined were smokers and nine non-smokers. Smokers and non-smokers did not differ in age or years of employment. Cadmium in air concentrations varied, but no definite trend was observed. The concentrations of cadmium in the blood and urine were found to be stable. Exposure to airborne cadmium was identical for smokers and non-smokers but average cadmium concentrations in the blood and urine of smokers were approximately twice as high as those in non-smokers. For the whole group, urinary cadmium was significantly correlated with years of employment, but no correlation was found between blood cadmium concentrations and exposure. For non-smokers, the correlation between cadmium in blood and years of employment was statistically significant (p less than 0.001). ...
Prevention is the key to managing cadmium exposure. No effective treatment for cadmium toxicity exists. For the general public, the primary source of exposure to cadmium is dietary. Smoking tobacco adds an additional burden of cadmium. Nutritional deficiencies can increase the risk of cadmium toxicity. Chronic cadmium exposure primarily affects the kidneys and secondarily the bones. Acute inhalation of fumes containing cadmium affects the lungs.
TY - JOUR. T1 - Adverse effects of cadmium exposure on mouse sperm. AU - Oliveira, Helena. AU - Spanò, Marcello. AU - Santos, Conceição. AU - Pereira, Maria de Lourdes. PY - 2009/12. Y1 - 2009/12. N2 - The effects of cadmium chloride exposure on sperm functional parameters were evaluated on eight-week-old ICR-CD1 male mice administered with a single s.c. injection of 1, 2 and 3 mg CdCl2/kg bw. Groups of animals treated with each dose, as well as their respective controls, were sacrificed after 24 h to detect short-term (acute) effects and after 35 days. Sperm cells were collected from the epididymis and several parameters of sperm quality and function were evaluated, namely density, morphology, motility, viability, mitochondrial function, acrosome integrity, together with DNA fragmentation assessed by the TUNEL assay. The short-term effects of cadmium chloride resulted in an increased fraction of sperm with abnormal morphology, premature acrosome reaction and reduced motility. Late term ...
Environmental cadmium exposure is associated with elevated risk of chronic otitis media in adults[4] "Chronic otitis media (COM) is caused by an infection of the middle ear, although it may also be associated with environmental pollutants. Recent reports found that cadmium exposure could be toxic to middle ear cell lines, but the role of cadmium in the development of COM in humans has not been examined to date. We hypothesised that environmental cadmium exposure was associated with an increased risk of COM in the general population. METHODS: We analysed cross-sectional data for 5331 adults of 20 years of age or above, obtained from the Korea National Health and Nutrition Examination Survey 2010-2012. We examined the association between blood cadmium levels and COM diagnosed by an otolaryngologist. RESULTS: The highest quartile group of cadmium blood concentration was associated with an OR of 3.33 (95% CI 1.78 to 7.53) for COM, after adjusting for potential confounding factors. Doubling blood ...
The ubiquitous food contaminant cadmium has features of an estrogen mimetic that may promote the development of estrogen-dependent malignancies, such as breast cancer. However, no prospective studies of cadmium exposure and breast cancer risk have been reported. , We examined the association between dietary cadmium exposure (at baseline, 1987) and the risk of overall and estrogen receptor (ER)-defined (ER+ or ER-) breast cancer within a population-based prospective cohort of 55,987 postmenopausal women. During an average of 12.2 years of follow-up, 2,112 incident cases of invasive breast cancer were ascertained (1,626 ER+ and 290 ER-). After adjusting for confounders, including consumption of whole grains and vegetables (which account for 40% of the dietary exposure, but also contain putative anticarcinogenic phytochemicals), dietary cadmium intake was positively associated with overall breast cancer tumors, comparing the highest tertile with the lowest [rate ratio (RR), 1.21; 95% confidence ...
Previous U.S. population modeling studies have reported that urinary cadmium (Cd) excretion patterns differ with age, sex, and dietary exposure; associations between Cd exposures and health outcomes also have differed by age and sex. Therefore, it is important to test models used to estimate Cd exposures across an expanded Cd-exposure range.,We estimated relative Cd exposures from both diet and smoking in low- and high-exposure scenarios to provide data for improving risk assessment calculations.,We used a Cd toxicokinetic-based model to estimate Cd exposures based on urinary Cd levels measured for 399 persons in a low-exposure area (Bangkok) and 6,747 persons in a high-exposure area (Mae Sot) in Thailand.,In Bangkok, we estimated dietary Cd exposures of 50-56 µg/day for males and 21-27 µg/day for females 20-59 years of age who never smoked. In Mae Sot, we estimated dietary Cd exposures of 188-224 µg/day for males and 99-113 µg/day for females 20-59 years of age who never smoked. In Bangkok, ...
Cadmium is an element that occurs naturally in the earths crust.� Pure cadmium is a soft, silver-white metal.� Cadmium is not usually present in the environment as a pure metal, but as a mineral combined with other elements such as oxygen (cadmium oxide), chlorine (cadmium chloride), or sulfur (cadmium sulfate, cadmium sulfide).� Cadmium is most often present in nature as complex oxides, sulfides, and carbonates in zinc, lead, and copper ores. It is rarely present in large quantities as the chlorides and sulfates.� These different forms of cadmium compounds are solids that dissolve in water to varying degrees.� The chlorides and sulfates are the forms that most easily dissolve in water.� Cadmium may change forms, but the cadmium metal itself does not disappear from the environment.� Knowing the particular form of cadmium, however, is very important when determining the risk of potential adverse health effects.

Cadmium poisoning through industrial exposure to inorganic cadmium fumes may produce fatigue, coughing, chest pain, a burning sensation in the throat, and renal damage. The prognosis of persons with cadmium-induced renal dysfunction is unfavorable, with urinary β-microglobulin and urinary protein the most important factors.2 Inhalation of cadmium fumes can lead to pneumonia with acute exposure and emphysema with chronic exposure.3. Cadmium poisoning is predominantly associated with cadmium fumes and/or inorganic cadmium salts that may be present in certain industrial environments. Cadmium and its inorganic compounds are commonly found in industry. Cadmium is utilized in many alloys and metal plating. Inorganic cadmium fumes or dusts are generally associated with heating, welding, and grinding of cadmium-containing metal products. Cadmium exposure in the general populace is derived from dietary intake, averaging 2−200 μg/day, and is only occasionally the precipitant of overexposure. In ...

The nephrotoxicity of cadmium at low levels of exposure, measured by urinary cadmium, has recently been questioned since co-excretion of cadmium and proteins may have causes other than cadmium toxicity. The aim of this study was to explore the relation between kidney function and low or moderate cadmium levels, measured directly in kidney biopsies ...
The cadmium (Cd) contaminated rice fields in Mae Sot District, Tak Province, Thailand has been one of the major environmental problems in Thailand for the last 10 years. We used disability adjusted life years (DALYs) to estimate the burden of disease attributable to Cd in terms of additional DALYs of Mae Sot residents. Cd exposure data included Cd and β2-microglobulin (β2-MG) in urine (as an internal exposure dose) and estimated cadmium daily intake (as an external exposure dose). Compared to the general Thai population, Mae Sot residents gained 10%-86% DALYs from nephrosis/nephritis, heart diseases, osteoporosis and cancer depending on their Cd exposure type and exposure level. The results for urinary Cd and dietary Cd intake varied according to the studies used for risk estimation. The ceiling effect was observed in results using dietary Cd intake because of the high Cd content in rice grown in the Mae Sot area. The results from β2-MG were more robust with additional DALYs ranging from 36%-86%
Our earlier work described that the roots of two maize cultivars, grown hydroponically, differentially responded to cadmium (Cd) stress by initiating changes in medium pH depending on their Cd tolerance. The current study investigated the root exudation, elemental contents and antioxidant behavior of the same maize cultivars (cv. 3062 (Cd-tolerant) and cv. 31P41 (Cd-sensitive)] under Cd stress. Plants were maintained in a rhizobox-like system carrying soil spiked with Cd concentrations of 0, 10, 20, 30, 40 and 50 mu mol/kg soil. The root and shoot Cd contents increased, while Mg, Ca and Fe contents mainly decreased at higher Cd levels, and preferentially in the sensitive cultivar. Interestingly, the K contents increased in roots of cv. 3062 at low Cd treatments. The Cd stress caused acidosis of the maize root exudates predominantly in cv. 3062. The concentration of various organic acids was significantly increased in the root exudates of cv. 3062 with applied Cd levels. This effect was ...
Introduction Agricultural soils in Iran, as in many other countries, are slightly to moderately contaminated by cadmium. According to some published reports, the average content of cadmium in some agricultural products and soils of Iran was found to be above the FAO/WHO guidelines. Abiotic stresses including cadmium stress can lead to overproduction of reactive oxygen species (ROS) causing progressive oxidative damage and ultimately cell death. In order to reduce cadmium-induced toxicity and alleviate some adverse effects of this metal on plants, a number of strategies including phytoremediation have been developed. Meanwhile, it was found that application of some elements such as calcium could diminish adverse effects of heavy metals in plants. In addition to calcium, selenium due to its potential in mitigation of cadmium toxicity has gained increased attention in recent decades. Selenium, as an antioxidant, plays an important role in the maintenance of human health, and on the other hand, many ...
Whole books and maybe encyclopedias could be written on pigments having the word cadmium in their common name. I dont recommend any cadmium paint because of the potential health hazard. Yes, I know: manufacturers say they are making safe cadmiums…but, in my opinion, who really knows. Therefore I dont press my luck. But, as so many of you use these pigments you should be aware of their virtues and their drawbacks. If you are not using a single pigment PY35 cadmium yellow, be aware of the additional pigment(s). If the additional pigment is an orange pigment the bias of that particular cadmium yellow will be orange. As in the case of a cadmium yellow hue, if the pigments have nothing to do with cadmium pigments, check on the bias of the pigments used to manipulate to achieve a cadmium yellow hue. If cadmium yellow has the word "deep" in its name, again, be assured that the bias will be orange. All yellow cadmiums made of PY37 are orange biased. Are you confused yet? I know I am. Why should any ...
Smoking is a strong risk factor for cardiovascular disease (CVD) and causes exposure to cadmium, which is a pro-atherosclerotic metal. Cadmium exposure has also been shown to increase the risk of CVD, even after adjustment for smoking. Our hypothesis was that part of the risk of CVD in smokers may be mediated by cadmium exposure from tobacco smoke. We examined this hypothesis in a mediation analysis, trying to assess how much of the smoking-induced CVD risk could be explained via cadmium. We used prospective data on CVD (incidence and mortality) in a Swedish population-based cohort of 4304 middle-aged men and women (the Malmö Diet and Cancer Study). Blood cadmium was analyzed in base-line samples from 1991, and clinical events were followed up for 16-19 years based on registry data. Mediation analysis was conducted to evaluate the indirect effect (via cadmium) of smoking on CVD. Survival was analyzed by the accelerated failure time (AFT) model and the Aalen additive hazard model. The mean blood cadmium
The accumulation of cadmium in plants cause a variety of physiological, biochemical and structural changes, while selenium that is often used in the process of biofortification of plants can significantly change the plants response to cadmium treatment. The main aim of this study was to determine the effect of cadmium on antioxidant enzyme gene expression in the roots and shoots of two varieties of wheat (Divana and Srpanjka) seedlings enriched with selenium. Enzymes that were observed in this study were glutathione S-transferase, Cu, Zn-Superoxid-Dismutase and catalase The effect of cadmium on antioxidant enzyme gene expression depended on the type of cultivar and the type of plant organ (root or shoot). Cadmium treatment affected the expression of glutathione S-transferase the most.The effect of cadmium on decrease in antioxidant enzyme gene expression was much more visible in the roots than in the shoots. Variety Divana was shown to be more sensitive to cadmium treatment than variety Srpanjka ...
Arsenic and cadmium are ranked among the top ten priority hazardous substances by the Agency for Toxic Substances and Disease Registry (ATSDR) [1]. Exposure to arsenic and cadmium can lead to adverse health outcomes such as lung and kidney cancers as well as cardiovascular disease and diabetes [2, 3]. Further, exposure to these two toxic and well-classified chemicals is of particular interest because of their extensive global impact [4-6]. For example, it is estimated that more than 40 million people worldwide drink water containing arsenic at concentrations that exceed the World Health Organization (WHO) and Environmental Protection Agency (EPA) drinking water guideline of 10 ppb [7]. Also, humans are exposed to low levels of cadmium through food consumption, typically ranging between 8 and 25 ug per day [3]. Smoking populations experience higher levels of cadmium exposure, as one cigarette may contain 1-2 ug cadmium [3].. Both arsenic and cadmium are classified as Group 1 carcinogens by the ...

Cardiovascular diseases (CVDs) remain the leading cause of death worldwide, including Qatar. Hypertension is one of the most common CVDs that contribute to this mortality. Cadmium is a well-known pollutant that has been suggested to be a risk factor for hypertension. However, the underlying mechanisms are still lacking. Very little is known about the effect of cadmium on the expression of vascular alpha- 1 adrenoceptors in vascular smooth muscle cells (VSMCs). This study was therefore undertaken to determine the effect of cadmium on the expression of vascular alpha-1 adrenergic receptors in vitro. Along with that, there are several phenotypic changes could modulate the VSMCs function and contribute to CVDs including hypertension. These changes include hypertrophy, migration and senescence. The second objective of this study was to determine the effect of cadmium on VSMCs phenotype. Human aortic smooth muscle cells (HASMCs) were incubated with different concentrations of cadmium chloride for varying
Cadmium has proatherogenic effects as shown in experimental and clinical studies.7, 8, 11, 20, 21 Atherosclerotic plaque is a known risk factor for ischemic stroke, and inflammation in the plaque is a critical mechanism for plaque rupture.7, 8, 22 Previous studies from the MDC and other cohorts have reported relationships between cadmium in blood and cardiovascular disease, including carotid plaque.4, 5, 6, 8 The present results show that cadmium and carotid plaque were associated with risk of future ischemic stroke in a synergistic manner. Since the whole population is exposed to cadmium through the diet and cadmium is eliminated very slowly from the human body, this observation could have important implications for public health.. The blood vessels have been identified as a target organ for cadmium accumulation.9 Cadmium has been associated with pro‐inflammatory effects, both in experimental and human studies.23 An in vitro study showed increased necrosis and apoptosis in macrophages exposed ...
Cadmium (Cd) is frequently used in various industrial applications and is a ubiquitous environmental toxicant, also present in tobacco smoke. An important route of exposure is the circulatory system whereas blood vessels are considered to be main stream organs of Cd toxicity. Our previous results indicate that cadmium chloride (CdCl2) affects mean arterial blood pressure in hypertensive rats. We hypothesized that Cd alters the intracellular calcium transient mechanism, by cadmium-induced stimulation of MAPKs (ERK 1 & 2) which is mediated partially through calcium-dependent PKC mechanism. To investigate this hypothesis, we exposed primary cultures of vascular smooth muscle cells (VSMCs) from wistar kyoto (WKY) and spontaneously hypertensive rats (SHR) to increased concentrations of CdCl2 on cell viability, expression of mitogen-activated protein kinases (MAPKs/ERK 1 & 2), and protein kinase C (PKC) which are activated by Cd in several cell types. The results from these studies indicate that CdCl2
Presence of cadmium in drinking water is hazardous to human health. Renal, cardiovascular, respiratory and skeletal effects have been found to be induced by cadmium exposure.

Cadmium and lead linked to hearing loss in U.S. adults.. Low levels of lead and cadmium may contribute to hearing loss, according to a large study of U.S. adults. Hearing loss was seen at metal concentrations common in the general population and below current workplace standards. Hearing ability dropped about 14 to 19 percent.. Loud noise can harm hearing but two common metals - lead and cadmium - may have a similar effect, according to a study published in Environmental Health Perspectives.. This study is unique because it links hearing loss and low-level exposures to lead and cadmium in a large sample of men and women in the United States. It is also the first to report cadmiums effects on hearing in adults.. This article originally appeared in the February 2013 issue of Environmental Health News..

Biochemical analyses can point to toxicant presence before its effects can be detected at higher organizational levels. We investigated responses of larval mass and alkaline phosphatase (ALP) to different cadmium treatments in 4th instar gypsy moth larvae from 20 full-sib families. Changes in trait values and trait plasticities as well as their variation were monitored after acute and chronic exposure or recovery from two cadmium concentrations (Cd(1) = 10 mu g and Cd(2) = 30 mu g Cd/g dry food). Larval mass only decreased, without returning to the control level at recovery stage following chronic cadmium challenge. Acute stress did not change trait value but increased genetic variance of larval mass. Significant ALP activity changes, sensitivity of isozyme patterns (Mr of 60, 64, and 85 kDa) and increased variation in ALP plasticity during acute exposure to cadmium point to its possible aplication as an exposure biomarker.

Proceedings of the SCOPE Workshop on Risk Assessment and Management of Environmental Cadmium (Ghent, Belgium, September 3-5, 2003) UNEP-SCOPE, Paris. Interpretive Summary: All crops accumulate some cadmium from soils, but some crops accumulate soil cadmium more effectively that others, and some soils are geochemically enriched in cadmium or contaminated with cadmium. Excessive lifetime cadmium consumption can cause renal tubular dysfunction in susceptible individuals, especially subsistence rice consumers. One method to minimize the possibility that consumers will ingest excessive cadmium in foods is to breed crop cultivars which accumulate lower levels of cadmium in the edible plant tissue (e.g., grain). Major or staple foods are of greater importance if breeding for low cadmium is needed, but minor foods which accumulate higher levels of cadmium than most other ...
Exposure to cadmium has been associated with carotid plaques, inflammation in carotid plaques, and increased risk of ischemic stroke. This study examined the separate and interacting effects of blood cadmium levels and carotid plaques on the risk of incident ischemic stroke.Cadmium levels were measured in 4156 subjects (39.2% men; mean±SD age 57.3±5.9 years) without history of stroke, from the Malmö Diet and Cancer cohort. The right carotid artery was examined using B-mode ultrasound examination at baseline. Incidence of ischemic stroke was monitored over a mean follow-up of 16.7 years. Carotid plaque was present in 34.5% of participants. Cadmium was significantly higher in subjects with plaque (mean±SD: 0.53±0.58 μg/L versus 0.42±0.49 μg/L; ...
1. Chromatography measurements indicated that adult rats converted 25-hydroxycholecalciferol into 1,25-dihydroxycholecalciferol at a lower rate than that reported earlier for young animals. In serum, less-polar metabolites were found which probably represented vitamin D esters and vitamin D3.. 2. A low dietary intake of calcium resulted in an evident increase in the fraction corresponding to 1,25-dihydroxycholecalciferol in the kidneys and also in the intestinal mucosa and serum.. 3. Inclusion of 0·67 mmol of cadmium/l of drinking water at a low dietary intake of calcium resulted in an increased accumulation of both cadmium and zinc in the kidneys and liver compared with values at a normal dietary calcium intake.. 4. At a normal dietary calcium intake, cadmium exposure caused inhibited production of 1,25-dihydroxycholecalciferol by the kidneys and an increased accumulation of 24,25-dihydroxycholecalciferol, vitamin D3 and vitamin D esters in the serum.. 5. The inhibitory effect of cadmium on ...

Exposure levels and exposure sources. Among subjects in this study, age, sex, smoking, and locality were sources of U-Cd variability. A comparison of observed U-Cd data from males and females who never smoked in the 20- to 39-year-old and 40- to 59-year-old groups in Mae Sot with respective counterparts in Bangkok indicated overall Cd exposure levels in Mae Sot to be 3- to 3.8-times greater than in Bangkok. Evidence supporting diet as a major source of high Cd exposures in Mae Sot comes from a previous report indicating that Cd levels in most staple food (rice) samples from Mae Sot were above the permissible limit of 0.2 mg/kg (Swaddiwudhipong et al. 2007). In another report, Cd content in 524 rice samples was 0.05-7.7 mg/kg, with over 90% of samples , 0.2 mg/kg (Simmons et al. 2005). Further, U-Cd levels were higher among persons who consumed locally grown rice compared with those who consumed rice purchased from other areas (Swaddiwudhipong et al. 2007). U-Cd levels were also higher in Mae Sot ...
Cadmium is a carcinogenic heavy metal. Urinary levels of cadmium are considered to be an indicator of long-term body burden, as cadmium accumulates in the kidneys and has a half-life of at least 10 years. However, the temporal stability of the biomarker in urine samples from a non-occupationally exposed population has not been rigorously established. We used repeated measurements of urinary cadmium (U-Cd) in spot urine samples and first morning voids from two separate cohorts, to assess the temporal stability of the samples.

On the potential exposure to toxic levels of cadmium: I was surprised to learn that one serving (46g) of sunflower seeds contains 23.9 ug (212 nanomoles) of cadmium (ref). The concentrated metal stocks we use for Maxpar labeling are 50 mM. If I did the math correctly, one serving of sunflower seeds contains the same amount of cadmium as 4.3 uL of a 50 mM cadmium stock. Admittedly, the cadmium in sunflower seeds could be much less bioavailable than a cadmium salt solution, but I just want to make the point that were not handling very high levels of metal in a typical CyTOF workflow ...
This 24-hour urine test is used to monitor exposure to cadmium. Cadmium is an extremely toxic metal frequently found in industrial places of work. Cigarettes are also a significant source of cadmium exposure. Cadmium may be found in batteries, fertilizers, pesticides, PVC plastics and certain shellfish. Those who work with cadmium pigments are also at risk for cadmium exposure. Cadmium toxicity affects the liver, placenta, lungs, brain, kidneys and bones, which may lead to problems such as fatigue, confusion, depression and cardiac arrhythmias. ...
Cadmium is a soft, malleable metal that, according to OSHA, can cause serious health problems for workers exposed to it. When using this metal, proper personal protective equipment must be worn because cadmium is highly toxic. Exposure to this metal is "known to cause cancer and targets the bodys cardiovascular, renal, gastrointestinal, neurological, reproductive, and respiratory systems," the administration states.. Cadmium is used today in batteries, alloys, plastic stabilizers and solar cells. OSHA estimates that 300,000 workers are exposed to the metal in the United States. Cadmium exposure can occur in all industry sectors, but construction and manufacturing have the highest exposure rates. The following workplace activities can lead to exposure:. ...
The purpose of this article is to emphasize that new nanomaterials offer a number of attractive alternatives for solar energy use in wastewater photocatalysis. The wastewater from the textile industry contains dyes and heavy metals. Thin films of cadmium doped TiO2 (Cd-TiO2) were coated by a doctor blade using TiO2 Degussa P25 and cadmium precursor (cadmium nitrate). The photocatalytic efficiency of cadmium doped TiO2 is strongly influenced by crystal structure, particle size, particle morphology, porosity and doping. The pore size distribution and the roughness analysis have been studied by the atomic force microscopy (AFM) of the thin films. The photocatalytic activity of the samples was tested in Methyl orange and Methylene blue photodegradation. Cadmium doped TiO2 catalyst does not significantly decrease the efficiency of photodegradation processes, and, in some situations, improves dye photodegradation ...

Sorption mechanisms have been long adopted for stabilising fine particles with the size scaling from micrometres to nanometres for water and wastewater treatments. Activated carbon in the form of powdered form (PAC) or granular form (GAC) have been the primary sorbent used in the treatments. The advantages of PAC or GAC are mainly due to the large specific surface area providing spaces for stabilising the fine particles present in water. In general, the smaller the size of the sorbent, the larger the specific surface area the sorbent has ...
Cadmium (Cd) is a non-essential heavy metal with high toxicity to plants. MicroRNAs (miRNAs) are a class of small non-coding RNAs that play important roles in plant abiotic stress responses. To investigate whether miRNAs function in Cd stress response, miRNA expression profiles in rice (Oryza sativa) under Cd stress were monitored using microarray assays. A total of 12 Cd-responsive novel miRNAs predicted previously were identified, of which four were further validated experimentally. 44 target genes were predicted for the Cd-responsive miRNAs, many of which appeared to regulate gene networks mediating environmental stresses. Several target genes were validated to show a reciprocal regulation by miRNAs. A transgenic approach was also used to determine the role of miRNAs in rice response to Cd stress. Overexpression of miR192 retarded seed germination and seedling growth under Cd stress. These results implied the role of novel miRNAs in the involvement of Cd tolerance of rice. (Read the full ...

Abstract : Cadmium is widely utilized in nickel-cadmium batteries, stabilizers, and coating applications due to its versatile physico-chemical properties. The aim of present study was to evaluate the impact of biofield treatment on atomic, thermal, and physical properties of cadmium powder. The cadmium powder was divided into two groups, one group as control and another group as treated. The treated group received Mr. Trivedis biofield treatment. Control and treated samples were characterized using X-ray diffraction (XRD), differential scanning calorimetry (DSC), particle size analyzer, surface area analyzer, and scanning electron microscopy (SEM). XRD results showed significant alteration in lattice parameter, unit cell volume, densities, nuclear charge per unit volume, and atomic weight in treated cadmium powder as compared to control. Furthermore, crystallite size was significantly reduced upto 66.69% in treated cadmium as compared to control. DSC analysis results showed that the latent heat ...

The cadmium powder was divided into two groups, one group as control and another group as treated. The treated group received Mr. Trivedis biofield treatment. Control and treated samples were characterized using X-ray diffraction (XRD), differential scanning calorimetry (DSC), particle size analyzer, surface area analyzer, and scanning electron microscopy (SEM). XRD results showed significant alteration in lattice parameter, unit cell volume, densities, nuclear charge per unit volume, and atomic weight in treated cadmium powder as compared to control. Furthermore, crystallite size was significantly reduced upto 66.69% in treated cadmium as compared to control. DSC analysis results showed that the latent heat ...
