Incidence and mortality rates of gastrointestinal (GI) and oral cancers are among the highest in the world, compared to other cancers. GI cancers include esophageal, gastric, colon, rectal, liver, and pancreatic cancers, with colorectal cancer being the most common. Oral cancer, which is included in the head and neck cancers category, is one of the most important causes of death in India.

The use of pesticides in farmland has increased considerably to protect crops against pests, weeds, and diseases. However, pesticides and/or their residues in ecosystems may affect non-target organisms. Indaziflam is a widely used herbicide in agricultural areas in the southern region of Turkey. Therefore, this study aimed to investigate the possible genotoxic and cytotoxic effects of indaziflam on HepG2 cells using comet assay, micronucleus assay, and xCELLigence.

Various circular RNAs (circRNAs) are novel class of non-coding RNAs, which are pervasively transcribed in the genome. CircRNAs play important roles in human, animals and plants. Up to now, there was no report regarding circRNAs of cleft palate by 2,3,7,8-tetrachlorodibenzo-pdioxin (TCDD) induce. The present study screened identification and characterization of differential expressed-circRNAs in TCDD-induced cleft palate. 6903 circRNAs candidates came from cleft palates.

BackgroundLymphocytes are a group of white blood cells with a variety of roles their integrity is crucial for the body’s immune responses. Cadmium, a heavy metal and environmental pollutant, is known as a toxicant to exert its adverse effects on some sort of cells including blood cells.Research DesignIn this study, human lymphocytes were divided into 3 groups: (1) lymphocytes at 0-h, (2) lymphocytes at 24 h (control), (3) lymphocytes treated with cadmium chloride (15 μM).

Increasing evidence supports the role of arsenic in dysregulated immune and inflammation responses, while, safe and effective treatments have not been fully examined. Rosa roxburghii Tratt (RRT), a traditional Chinese edible fruit with potential immunoregulatory activities, was considered as a dietary supplement to explore its protective effects and possible mechanism in arsenic-induced dysregulated inflammation responses.

Arsenic trioxide (ATO) has been found to be effective in acute promyelocytic leukemia. However, ATO-induced severe cardiotoxicity limits its clinical application. To date, the mechanisms of ATO-induced cardiotoxicity remain unclear. It is hypothesized that ferroptosis may trigger ATO-induced cardiotoxicity; however, this has not yet been investigated. To clarify this hypothesis, rat cardiomyocyte H9c2 cells were treated with ATO with or without ferrostain-1 (Fer-1).

IntroductionThe present study was undertaken to investigate the prognostic value of the frontal QRS-T angle associated with adverse cardiac outcomes in patients with carbon monoxide (CO) poisoning in early stages in the emergency department.Materials and methodsThe data of 212 patients with CO poisoning who were admitted to the ED between January 2010 and May 2020 were retrospectively analyzed.

Due to the prevalence of hypertension (one of the major risk factors of CVD) in the population, it is necessary to explore the adverse effects of daily tolerable and “safe” dose of bisphenol A (BPA) under hypertensive conditions. The current study exposed the Nω-nitro-l-arginine methyl ester (L-NAME, 40 mg/kg b.w/day) induced hypertensive Wistar rats to BPA (50 μg/kg b.w/day) by oral administration along with appropriate controls for 30 days period.

Inorganic arsenic (iAs) exposure is a serious health problem that affects more than 140 million individuals worldwide, mainly, through contaminated drinking water. Acute iAs poisoning produces several symptoms such as nausea, vomiting, abdominal pain, and severe diarrhea, whereas prolonged iAs exposure increased the risk of several malignant disorders such as lung, urinary tract, and skin tumors.

Background: Acrylamide (ACR), an important endogenous contaminant in carbohydrate-rich foods, has been involved in various negative effects on multiple organ networks, including the reproductive system. Previous studies have reported that ACR affects oocyte quality and fertility. Purpose: This study aimed to explore the toxic effects and regulatory mechanisms of ACR on mouse germinal vesicle (GV) oocytes.

Resveratrol has been reported as an ideal medicine in the treatment of colorectal cancer. Meanwhile, cadmium could affect the occurrence and development of tumors in various ways. Epithelial–mesenchymal transition is a major progress regulated with colorectal cancer (CRC). We aimed to determine the effect and mechanism of resveratrol on the Cd-promoted EMT in CRC cells.

BackgroundIntoxication with cadmium (Cd) ions leads to hippocampal damage and cognitive impairment.

Pyrethroid pesticides are frequently used for household insect control of insects and in agriculture and livestock. Flumethrin is a pyrethroid that is used against ectoparasites in many animals. The goal of this study was to evaluate the cytotoxic, apoptotic, genotoxic, and estrogenic effects of flumethrin on the mammalian breast cancer cell line (MCF-7). Compared with control groups, a dose-dependent decrease was observed in cell viability at concentrations of 100 µM and higher.

Exposure through arsenic-contaminated air and food caused by the burning of coal is a major environmental public health concern in Guizhou Province of China. Previous studies have shown that immunological dysfunction is involved in the pathogenesis and carcinogenesis of arsenic; however, knowledge regarding effective prevention measures have not been fully examined.

In this study, the level of arsenic (As), lead (Pb) and cadmium (Cd) and also essential elements in beer samples consumed in Turkey were investigated using the inductively coupled plasma mass spectrometry (ICP-MS) method. The heavy metal-induced non-carcinogenic and carcinogenic risks were calculated. For essential elements, the calculated estimated daily intake of iron (Fe), copper (Cu), selenium (Se) and cobalt (Co) from beer consumption were compared with their toxicity reference values.

Introduction:Environmental arsenic contamination is a major toxicological problem worldwide due to its carcinogenic and nephrotoxic potential.Aim:The purpose of this observational study was to determine the suspected association between urinary arsenic (uAs) and urinary leucine (or leucyl) aminopeptidase 3 (uLAP3) to evaluate uLAP3 as a candidate biomarker of exposure to airborne arsenic.Materials and Methods:A total of 918 adults occupationally and/or environmentally exposed to airborne arse

Chrysene, one of the basic polycyclic aromatic hydrocarbons (PAHs), has been reported to make damages to human health and living environment. Chronic obstructive pulmonary disease (COPD) is a progressive disorder with high morbidity and mortality. To investigate the role of chrysene in the development of COPD, male C57BL/6 mice were exposed to the cigarette smoke (CS) followed with the administration of chrysene.

Although melamine exposure induces cognitive deficits and dysfunctional neurotransmission in hippocampal Cornus Ammonis (CA) 1 region of rats, it is unclear whether the neural function, such as neural oscillations between hippocampal CA3–CA1 pathway and postsynaptic receptors involves in these effects.

Lead is a ubiquitous heavy metal toxin of significant public health concern. Every individual varies in their response to lead’s toxic effects due to underlying genetic variations in lead metabolizing enzymes or proteins distributed in the population. Earlier studies, including our lab, have attributed the influence of ALAD (δ-Aminolevulinate dehydratase) polymorphism on blood lead retention and ALAD activity.

Arsenic, a major environmental toxicant and pollutant, is a global public health concern. Among its many adverse effects, arsenic is immunotoxic, but its effects on human neutrophil functions are not yet well-defined.

Bisphenol A (BPA), an imperative environmental contaminant used in polycarbonate plastics. Due to limited information concerning the effect of BPA on lungs, this study design to assess whether BPA cause alterations in histopathology and trace metal content in lungs of rats. They were divided into five groups with five rats per group. Group I was named as control group. Group L6 and L12 were received BPA (10 mg/kg body weight/day) for 6 weeks and 12 weeks respectively.

Aim:Bisphenol-A (BPA) is an endocrine disrupting compound and may exacerbate or induce allergic diseases. To the best of our knowledge, there is little evidence regarding the effects of BPA exposure on allergic rhinitis (AR) in children. In the present study, we sought to examine whether exposure to BPA in children is associated with AR.Methods:This study was designed as a case controlled clinical study.

Cleft palate (CP), a congenital defect in the oral and maxillofacial regions, is difficult to detect prenatally. This study investigated the correlation between differentially expressed proteins in serum and CP induced by all-trans retinoic acid (atRA) and 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) in mice.

Malathion is an organophosphate pesticide widely used for agricultural crops and for vector control of Aedes aegypti. Humans are exposed to this environmental contaminant by ingesting contaminated food. The juvenile and peripubertal periods are critical for the postnatal development of the epididymis and are when animals are most vulnerable to toxic agents.
