Résumé :

Vision is an important sense for humans, and visual impairment/blindness has a huge impact in daily life. The retina is a nervous tissue that is essential for visual processing since it possesses light sensors (photoreceptors) and performs a pre-processing of visual information. Thus, retinal cell dysfunction or degeneration affects visual ability and several general aspects of the day-to-day of a person’s lives. The retina has a blood–retinal barrier, which protects the tissue from a wide range of molecules or microorganisms. However, several agents, coming from systemic pathways, reach the r

Résumé :

Among the endocrine organs, the adrenal cortex appears to be the most vulnerable to chemically induced injury. A wide variety of chemicals has been found to cause morphological or functional lesions in the gland. Some of the lesions are highly localized to specific anatomical zones of the adrenal cortex, and the resulting functional deficits depend on the physiological role(s) of the zone affected. In addition, metabolic activation is an important factor contributing to the gland's vulnerability to chemical injury. For example, carbon tetrachloride (CCl4) causes adrenocortical necrosis, but on

Résumé :

Organ toxicity caused by chemicals is a serious problem in the creation and usage of chemicals such as medications, insecticides, chemical products, and cosmetics. In recent decades, the initiation and development of chemical-induced organ damage have been related to mitochondrial dysfunction, among several adverse effects. Recently, many drugs, for example, troglitazone, have been removed from the marketplace because of significant mitochondrial toxicity. As a result, it is an urgent requirement to develop in silico models that can reliably anticipate chemical-induced mitochondrial toxicity.

Abstract The liver performs many vital functions such as regulating homeostasis, bile production, storage of vitamins, and more. Another important function of the liver is to neutralize toxic substances entering the body. Substances entering the human body can be eliminated unchanged, retained unchanged, or undergo chemical transformation. Drugs are one of the most important and common causes of hepatotoxicity.

Résumé :

The lung is a target organ for the toxic effects of several chemical agents, including natural products, industrial chemicals, pesticides, environmental agents, and occasionally, drugs. Factors that establish the lung as a target organ include selective tissue exposure, high tissue oxygenation, and the presence of bioactivating systems that can generate toxic products from initially innocuous substances. Selective pulmonary exposure most often results from the fact that the lung serves as the major portal of entry for most airborne substances, but in some cases, selective exposure is the conse

There is overwhelming evidence that the microbiome must be considered when evaluating the toxicity of chemicals. Disruption of the normal microbial flora is a known effect of toxic exposure, and these disruptions may lead to human health effects. In addition, the biotransformation of numerous compounds has been shown to be dependent on microbial enzymes, with the potential for different host health outcomes resulting from variations in the microbiome.

The Eastern Newt (Notophthalmus viridescens (Rafinesque, 1820)), which possesses tetrodotoxin—a toxin for chemical defense, is most vulnerable to predation during its larval stage. We assessed whether exposing Eastern Newt larvae to predator scent cues (from dragonfly larvae) would elicit chan

Résumé :

Microphysiological systems (MPS) and computer simulation models that recapitulate the underlying biology and toxicology of critical developmental transitions are emerging tools for developmental effects assessment of drugs/chemicals. Opportunities and challenges exist for their application to alternative, more public health relevant and efficient chemical toxicity testing methods. This is especially pertinent to children’s health research and the evaluation of complex embryological and reproductive impacts of drug/chemical exposure. Scaling these technologies to higher throughput is a key chal

Résumé :

Ximenia americana L., popularly known in Brazil as “ameixa do-mato, ameixa-brava, and ameixa-do-sertão,” is widely used in folk medicine to treat several intestinal disorders. The present study assessed the potential mechanisms of action underlying the gastroprotective activity of the hydroethanolic extract of Ximenia americana L. (EHXA) stem bark. The acute toxicity of EHXA was estimated, and later, the gastroprotective effect in mice was assessed through acute models of gastric lesions induced by acidified or absolute ethanol and indomethacin, where the following mechanisms were pharmacologi

Résumé :

Chemicals can exhibit significant toxic properties. While for most compounds, unspecific cell damaging processes are assumed, a plethora of chemicals exhibit characteristic odors, suggesting a more specific interaction with the human body. During the last few years, G-protein-coupled receptors and especially chemosensory ion channels of the transient receptor potential family (TRP channels) were identified as defined targets for several chemicals. In some cases, TRP channels were suggested as being causal for toxicity. Therefore, these channels have moved into the spotlight of toxicological re

Résumé :

Cell proliferation has long been recognized as a basic component of multistage carcinogenesis. Based largely on the finding that certain nongenoloxic chemical carcinogens induce cell proliferation in the same organ that develops tumors after long-term exposure, some suggest that the increased rates of cell division account for the carcinogenicity of these chemicals. This paper examines relationships between chemically induced liver toxicity, cell proliferation, and liver carcinogenesis; major factors include consistency, transient vs. sustained dose-response correspondence, and scientific plau

Résumé :

Industrial wastes may produce leachates that can contaminate the aquatic ecosystem. Toxicity testing in acute and chronic levels is essential to assess environmental risks from the soluble fractions of these wastes, since only chemical analysis may not be adequate to classify the hazard of an industrial waste. In this study, ten samples of solid wastes from textile, metal-mechanic, and pulp and paper industries were analyzed by acute and chronic toxicity tests withDaphnia magnaandVibrio fischeri. A metal-mechanic waste (sample MM3) induced the highest toxicity level toDaphnia magna(CE50,48 h=2

Currently, a lot of researcher’s attention is devoted to the problem of microbiologically influenced corrosion (MIC), since it causes huge damages to the economy, initiating the destruction of oil and gas pipelines and other underground constructions. To protect industrial materials from MIC effects an organic chemical inhibitors are massively used. However, the problem of their use is associated with toxicity, dangerous for the environment that caused the need for development the alternative methods of MIC repression.
