Groups of 10 male and 10 female rats were admin istered 0, 25, 50, 100, 200, or 400 mg oleic acid diethanolamine condensate/kg body weight in ethanol dermally for 13 weeks. All male and female rats survived until the end of the study. The final mean body weights and body weight gains of 200 and 400 mg/kg males and the mean body weight gain of 400 mg/kg females were significantly less than those of the vehicle controls. The only chemical-related clinical finding was irritation of the skin at the site of application in most males administered 100 mg/kg or greater and in all females administered 50 mg/kg or greater. Segmented neutrophil counts were increased relative to the vehicle controls in the 400 mg/kg male group on days 5 and 19, in the 200 mg/kg female group on day 19 and at week 13, and in the 400 mg/kg female group on days 5 and 19 and at week 13.

Groups of 50 male and 50 female mice received dermal applications of pyrogallol in 95% ethanol at doses of 0, 5, 20, or 75 mg pyrogallol/kg body weight, 5 days per week for up to 105 weeks. Survival of dosed groups of male mice was similar to that of the vehicle control group. Survival was significantly decreased in 75 mg/kg females; most early deaths in this group were due to ulcers at or adjacent to the site of application. The mean body weights of 75 mg/kg female mice were generally over 10% less than those of the vehicle controls during year 2 of the study. Irritation and/or ulceration of the skin at the site of application were the only chemical-related clinical findings and occurred predominantly in the 20 and 75 mg/kg groups. In the skin at the site of application, the incidence of squamous cell carcinoma in 75 mg/kg females was significantly greater than that in the vehicle control group. Two 75 mg/kg males had squamous cell papillomas; squamous cell papillomas have not been observed in ...

Oral and dermal carcinogenicity studies have been conducted on waxes, and were judged to be negative, i. e., the waxes were not considered to be carcinogenic. Based on a report that the application dose in the dermal carcinogenesis studies was approximately 7.5 mg, applied three times per week, and assuming an average body weight for the mice of 25 g, the average daily dose in the dermal studies was approximately 128 mg/kg/day. In a key carcinogenicity study (Klimisch score = 2), five petroleum waxes (3 of the waxes were microcrystalline and the other two were unidentified) were given to male and female Sprague-Dawley rats at a dietary concentration of 10% for 2 years (Shubik et al., 1962). Survival rates and growth rates were unaffected by oral exposure to any of the waxes tested. A number of tumours were found in all groups at necropsy. The most common tumours were those of the mammary regions (fibrocarcinomas, adenocarcinomas, fibromas, and sarcomas), of the adrenal glands (cortical adenomas ...
In a 103-week carcinogenicity study, the read-across substance DEHA was administered to F344 rats and B6C3F1 mice in the diet at levels of 12000 or 25000 ppm, equivalent to a daily intake of 600 or 1250 mg/kg of body weight in rats and 1715 or 3570 mg/kg of body weight in mice (conversion based on data from the WHO report (2004)). No test substance related tumors were found in the rat (no increased tumour incidences). In the (female) mice an increased number of hepatocellular carcinomas was found at both doses. Hepatocellular adenomas and carcinomas occured combined in high-dose mice of both sexes and in low-dose female mice at incidences that were dose-related and significantly higher than those in control mice. The association of liver tumours in male mice with the administration of DEHA was not considered to be conclusive because the increased number of liver tumours in males reflected only an increase in adenomas in the high-dose group and because the time to observation of tumours was not ...
An independent study done by European Ramazzini Foundation of Oncology and Environmental Sciences in Italy shows the intake of aspartame at far less than daily allowable levels is multi-carcinogenic (lymphomas and leukemias) in laboratory rats. Aspartame is marketed as Nutrasweet, Equal, and Aminosweet and commonly found in diet products such as diet sodas.. First Experimental Demonstration of the Multipotential Carcinogenic Effects of Aspartame Administered in the Feed to Sprague-Dawley Rats. Our study shows that APM is a multipotential carcinogenic compound whose carcinogenic effects are evident even at a daily dose of 20 mg/kg bw, much less than the current ADI for humans in Europe (40 mg/kg bw) and in the United States (50 mg/kg bw).. The results of carcinogenicity bioassays in rodents are consistent predictors of human cancer risks (Huff 1999; Rall 1995; Tomatis et al. 1989). The results of our study therefore call for an urgent reexamination of the present guidelines on the use and ...

Probably not the type of diet you are thinking of. It has something to do with food, though. I am talking about the transfer mechanisms some bacteria use to share metabolites between them, and also with bacteria of different species. In this review published in Environmental Science: Processes & Impacts, two researchers from North Carolina analyse the latest discoveries in this field, specifically in mechanisms known as DIET: direct interspecies electron transfer.. Scientists discovered DIET not a decade ago. Before that, only conventional diffusion models were known: an organism generated an excess of certain metabolite, released it to the surrounding media and was consumed by a second organism. This is called mediated interspecies electron transfer (MIET).. DIET, however, is more efficient. Instead of releasing the metabolites around, bacteria use structures that allow them to transfer chemical substances directly to other cells. These structures, usually filamentous pili full of ...

Please check back later for the full article.The burden of ill health has shifted, globally, from communicable to non-communicable disease, with poor health clustering in areas of economic deprivation. However, for the most part, public health programs remain focused on changing behaviors associated with poor health (such as smoking or physical inactivity) rather than the contexts that give rise to, and influence, the wide range of behaviors associated with poor health. This way of understanding and responding to population ill health views poor health behavior as a defining

No carcinogenicity studies have been performed with levocetirizine. However, evaluation of cetirizine carcinogenicity studies are relevant for determination of the carcinogenic potential of levocetirizine. In a 2-year carcinogenicity study, in rats, cetirizine was not carcinogenic at dietary doses up to 20 mg/kg (approximately 15 times the maximum recommended daily oral dose in adults, approximately 10 times the maximum recommended daily oral dose in children 6 to 11 years of age and approximately 15 times the maximum recommended daily oral dose in children 6 months to 5 years of age on a mg/m2 basis). In a 2-year carcinogenicity study in mice, cetirizine caused an increased incidence of benign hepatic tumors in males at a dietary dose of 16 mg/kg (approximately 6 times the maximum recommended daily oral dose in adults, approximately 4 times the maximum recommended daily oral dose in children 6 to 11 years of age, and approximately 6 times the maximum recommended daily oral dose in children 6 ...

Due to recent advances in data storage and sharing for further data processing in predictive toxicology, there is an increasing need for flexible data representations, secure and consistent data curation and automated data quality checking. Toxicity prediction involves multidisciplinary data. There are hundreds of collections of chemical, biological and toxicological data that are widely dispersed, mostly in the open literature, professional research bodies and commercial companies. In order to better manage and make full use of such large amount of toxicity data, there is a trend to develop functionalities aiming towards data governance in predictive toxicology to formalise a set of processes to guarantee high data quality and better data management. In this paper, data quality mainly refers in a data storage sense (e.g. accuracy, completeness and integrity) and not in a toxicological sense (e.g. the quality of experimental results). This paper reviews seven widely used predictive toxicology data
Rats administered doses up to 43 mg/kg/day in males and 52 mg/kg/day in females had no increases in tumor incidence, with the exception of a modest increase in the frequency of mammary gland fibroadenomas in female rats receiving doses ≥5.4 mg/kg (P,0.015). The highest doses of tamsulosin hydrochloride evaluated in the rat carcinogenicity study produced systemic exposures (AUC) in rats 3 times the exposures in men receiving the maximum therapeutic dose of 0.8 mg/day.. Mice were administered doses up to 127 mg/kg/day in males and 158 mg/kg/day in females. There were no significant tumor findings in male mice. Female mice treated for 2 years with the two highest doses of 45 and 158 mg/kg/day had statistically significant increases in the incidence of mammary gland fibroadenomas (P,0.0001) and adenocarcinomas (P,0.0075).

Tipranavir was neither mutagenic nor clastogenic in a battery of five in vitro and animal in vivo screening tests. Long-term carcinogenicity studies in mice and rats have been conducted with tipranavir. Mice were administered doses ranging from 30 to 300 mg/kg/day tipranavir, with or without 40 mg/kg/day ritonavir; all doses resulted in systemic exposures below those in humans receiving the recommended dose. Incidence of benign hepatocellular adenomas, combined adenomas/carcinomas, and hepatocellular carcinoma was increased in both sexes with tipranavir/ritonavir. The clinical relevance of the carcinogenic findings in mice is unknown. Rats were administered doses ranging from 30 to 300 mg/kg/day tipranavir, with or without ritonavir. No drug-related findings were observed in male rats. At the highest dose of tipranavir (approximately equivalent to exposure in humans at the recommended therapeutic dose), an increased incidence of benign follicular cell adenomas of the thyroid gland was observed ...
US Food and Drug Administration Statement on European Aspartame Study. CFSAN/Office of Food Additive Safety. April 20, 2007. The FDA has completed its review concerning the long-term carcinogenicity study of aspartame, conducted by the European Ramazzini Foundation (ERF), located in Bologna, Italy. FDA reviewed the study data made available to them by ERF and finds that it does not support ERFs conclusion that aspartame is a carcinogen. Additionally, these data do not provide evidence to alter FDAs conclusion that the use of aspartame is safe.. Aspartame was first approved in the United States in 1981 and is one of the most widely used artificial sweeteners. When metabolised by the body, aspartame is broken down into two common amino acids, aspartic acid and phenylalanine, and a third substance, methanol. These three substances are available in similar or greater amounts from eating common foods.. Considering results from the large number of studies on aspartames safety, including five ...

These are critical tests with any new drug because it determines possible dangers to unborn children when their mothers are exposed to the product during pregnancy. He found that technicians responsible for the tests had no formal training in teratology or toxicology. In fact, they were given some books by the company and trained themselves for 3 months. Of most concern was the way the carcinogenicity tests were conducted. These are tests to see if the product could cause cancer. According to the law, any product intended as a food product cannot have demonstrated cancer-causing ability at a dose 100X that commonly consumed. Even though the tests were poorly conducted they did demonstrate that aspartame was associated with a dramatic, dose-dependent, increase in a variety of brain tumors-mainly astrocytomas-the type commonly seen in humans. This means that the higher the dose of aspartame the more tumors that were ...

FAME, the French Absorption spectroscopy beamline in Material and Environmental science, is dedicated to X-ray absorption spectroscopy. FAME covers a wide variety of scientific fields (materials science, biophysics, chemistry) but focuses mainly in geochemical sciences where, in most cases, the probed elements are highly diluted.. FAME being a bending magnet beamline, the optical elements have been designed in order firstly to maximize the photon flux on the sample and secondly to optimize the beamline stability and reduce the non-statistical noise (Proux et al. Journal of Synchrotron Radiation 13 (2006) 59-68). Moreover, for an optimal acquisition of XAS spectra on diluted elements, the intense x-ray beam on the sample needs to be associated with a highly sensitive detection system: fluorescence detection is achieved with a 30-element Canberra Ge solid state detector.. Opened to users since 2002, the beamline offers several sample environments, either to improve the measurements (helium ...
Environmental sciences address a broad variety of problems requiring an interdisciplinary approach. Such problems include ecosystem changes, extreme events, earth processes, pollution, effects of global climate change. These issues are characterized by great process complexity with associated large datasets, typically in space and time, resulting in high dimensionality for models.. Multilevel modelling facilitates the understanding of complex; environmental phenomena; in particular, hierarchical Bayesian models constitute an efficient tool to exploit diverse sources of information, to accomodate influences that are unknown, and to draw inference on large numbers of latent variables and parameters that describe complex relationships. Furthermore, such analyses offer the possibility of providing a consequential societal impact in terms of environment regulation and public policy. Examples include assessment of the effects of climate change, interpolating and predicting exposure to environmental ...

This is an advance summary of a forthcoming article in the Oxford Research Encyclopedia of Environmental Science. Please check back later for the full article. In 1945, the Amazon biome was still mostly intact. The scars of ancient cultural developments in Andean and lowland Amazon had healed, and the impacts of rubber and other resource exploitation were reversible. Very few roads existed, and only in its periphery. In the 1950s and especially in the 1960s, Brazil and other Andean countries launched ambitious road building and colonization projects, largely driven by Brazilian geopolitical concerns. Interest in the Amazon became much more intense in the 1970s as forest loss began to raise worldwide concern. Construction of more and better roads continued at an exponentially growing pace in each following decade, multiplying correlated deforestation and forest degradation everywhere in the Amazon. A point of no return was reached when interoceanic roads crossed the borders of Brazilian-Andean ...
