Infectious diseases pose a serious threat to global biodiversity. However, their ecological impacts are not independent of environmental conditions. For example, the pathogenic fungus Batrachochytrium dendrobatidis (Bd), which has contributed to population declines and extinctions in many amphibian species, interacts with several environmental factors to influence its hosts, but potential interactions with other pathogens and environmental contaminants are understudied. We examined the combined effects of Bd, a water mold (Achlya sp...

Phosphorus (P) intake, genotype, and growth environment in soybean cultivation can affect the composition of the soybean. This experiment was conducted in two locations (microregions I and II) using a randomized complete block design, including conventional soybean (BRS Sambaíba) and genetically modified (GM) [Msoy 9144 Roundup Ready (RR)] cultivars and varying doses of phosphorus fertilizer (0, 60, 120, and 240 kg/ha P2O5). Soybeans were evaluated for chemical composition, total phenols, phytic acid content, individual isoflavone content, antioxidant activity, oil quality, fatty acid profile, total carotenoid content, and individual tocopherol contents...

Petit-High Pressure Carbon Dioxide (p-HPCD) is a promising nonthermal technology for foods pasteurization. Cluster analysis of gene expression profiles of Saccharomyces cerevisiae exposed to various stresses exhibited that gene expression profile for p-HPCD stress (0.5MPa, 25°C) was grouped into a cluster including profiles for Sodium Dodecyl Sulfate and Roundup herbicide. Both are detergents that can disorder membrane structurally and functionally, which suggests that cell membrane may be a target of p-HPCD stress to cause cell growth inhibition...

Roundup(®) formulations are the most consumed glyphosate-based herbicides in the world. When applied, they may reach water bodies and exert toxicity toward non-target species. This study evaluated and compared the effects of different variations of Roundup on biochemical biomarkers as oxidative parameters and Acethylchorinesterase (AChE) activity, and sperm quality of the livebearing Jenynsia multidentata. Fish were acutely (96 h) exposed to Roundup Original(®) (RO), Roundup Transorb(®) (RT) and Roundup WG(®) (RWG) at 0...

The goal of the present study was to elucidate the in vitro cytotoxicity of Roundup and to reveal the possible related mechanisms in L-02 hepatocytes. By detecting reactive oxygen species (ROS) production, glutathione (GSH)/superoxide dismutase (SOD) levels, mitochondrial permeability transition pore (PTP) open rate, apoptosis-inducing factor (AIF) release, intracellular Ca(2+) concentration, and alanine aminotransferease (ALT)/aspartate aminotransferase (AST) leakage, we determined that Roundup induced anti-oxidant system inhibition, mitochondria damage, DNA damage, membrane integrity and permeability changes, and apoptosis in L-02 hepatocytes...

We investigated the effects of different concentrations of glyphosate acid and one of its formulations (Roundup) on seed germination of two glyphosate-resistant (GR) and one non-GR variety of soybean. As expected, the herbicide affected the shikimate pathway in non-GR seeds but not in GR seeds. We observed that glyphosate can disturb the mitochondrial electron transport chain, leading to H2O2 accumulation in soybean seeds, which was, in turn, related to lower seed germination. In addition, GR seeds showed increased activity of antioxidant systems when compared to non-GR seeds, making them less vulnerable to oxidative stress induced by glyphosate...

BACKGROUND: A previous 2-year rat feeding trial assessing potential toxicity of NK603 Roundup-tolerant genetically modified maize revealed blood and urine biochemical changes indicative of liver and kidney pathology. In an effort to obtain deeper insight into these findings, molecular profiling of the liver and kidneys from the same animals was undertaken. RESULTS: Transcriptomics showed no segregation of NK603 maize and control feed groups with false discovery rates ranging from 43 to 83% at a cut-off p value of 1%...

Glyphosate-based herbicides include active matter and adjuvants (e.g. polyethoxylated tallow amines, POEAs). In addition to a previous investigation on the effect of glyphosate on oysters, the aim of the present study was to investigate the effects of sub-chronic exposures (35days) to three concentrations (0.1, 1 and 100μgL(-1)) of Roundup Express® (REX) and POEAs on oysters belonging to the same age group. Low mortality rates were calculated, and only few significant differences (i.e. shell length) between exposure conditions were observed at a given date...

Exposure to the herbicides Paraquat (PQ) and Roundup(®) may cause cell lesions due to an increase in oxidative stress levels in different biological systems, even in the reproductive system. OBJECTIVE: Evaluate the possible changes in reproductive parameters and hepatic, as well as its prevention by simultaneous application of melatonin. METHODS: Thirty-five female rats at the age of 3 months were divided into seven groups: three groups exposed to sub-lethal doses of the herbicides PQ (50mg/kg) and Roundup(®) (500mg/kg) (n=5, G2, G3 and G4); three groups exposed to herbicides and simultaneous treatment with 10mg/kg of Melatonin (n=5, G5, G6 and G7) and control group (n=5, G1) from the first to the seventh day of pregnancy...
