Spindle poisons elicit various cellular responses following metaphase arrest, but how they relate to long-term clonogenicity has remained unclear. We prepared several HeLa lines in which the canonical apoptosis pathway was attenuated, and compared their acute responses to paclitaxel, as well as long-term fate, with the parental line. Three-nanomolar paclitaxel induced brief metaphase arrest (<5 h) often followed by aberrant mitosis, and about 90% of the cells of each line had lost their clonogenicity after 48 h of the treatment...

BACKGROUND: There is an increasing interest in herbal products as a self-medication method in recent years. Some plant extracts either turn into drugs over time or are consumed directly without treatment. One of these plants is Nerium oleander L., which is a potentially lethal plant, since it has cardiac glycosides. However, numerous researches of its extracts have been performed against cancer cell lines in recent literature. This contradiction leads to misinterpretation and induces the prevalence of intoxication or fatal cases...

Lead (Pb) poisoning via ingestion of shot pellets is a frequent cause of death in wild birds and also has a wide range of subclinical effects. Here we report on the sublethal effects Pb exposure has on the breeding performance of red-legged partridges (Alectoris rufa). We studied the effects of Pb exposure on sperm quality, reproductive success, egg properties, laying performance, antioxidants levels and carotenoid-based colouration. Birds were exposed by oral gavage to one or three No. 6 Pb shot pellets (2...

The consumption of food containing high amounts of histamine and other biogenic amines can cause food poisoning with different symptoms linked to the individual sensitivity and the detoxification activity. Histamine is the only biogenic amine with regulatory limits set by the European Commission in fish and fishery products, because it can lead to a fatal outcome. However, also fermented foods can be involved in outbreaks and sporadic cases of intoxication. The factors affecting the presence of histamine in food are variable and product specific including the availability of the precursor amino acid, the presence of microorganisms producing decarboxylases, and the conditions allowing their growth and enzyme production...

The use of earths and clays for medical purposes dates back to antiquity. In recent years, there has been an increasing interest in researches on traditional remedies in the hope of discovering new drug. Iran is an ancient country with a medical backbone acquired from the experiences of ancient Persian scholars, who had made a great contribution to the development of the medical sciences. Many medical and pharmaceutical books by early Persian scientists still exist and may have the potential of leading researchers to new drug discoveries...

BACKGROUND: Improper use, storage, and disposal of prescribed opioids can lead to diversion or accidental poisoning. Our previous study showed a large proportion of cancer patients have unsafe opioid practices. Our objective was to determine whether an improvement occurred in the patterns of use, storage, and disposal of opioids among cancer outpatients after the implementation of a patient educational program. PATIENTS AND METHODS: Our palliative care (PC) clinic provides every patient with educational material (EM) on safe opioid use, storage, and disposal every time they receive an opioid prescription...

Lead (Pb) is an environmental pollutant associated with several diseases, such as nephrotoxicity. Methylglyoxal (MG) is a reactive dicarbonyl compound formed during glycolysis and reported to increase in kidney damage. Metformin is used as a MG scavenger in the clinic. In this study, we investigated the mechanism of Pb-induced renal injury and the effect of metformin on Pb-induced nephrotoxicity. Eighteen Wistar rats were randomly divided into three groups: control, Pb, and Pb + metformin groups. Pb (250 ppm) was administered in drinking water, and 50 mg/Kg of metformin was co-administered orally...

BACKGROUND: Tetramine (tetramethylene disulphotetramine, TETS) and fluoroacetamide (FAA) are known as illegal rodenticides with high toxicity to animal species and human beings, which could lead to severe clinical features, including reduction of consciousness, convulsions, coma, and even death. METHODS AND RESULTS: We presented 2 cases that involved rodenticides poisoning. Even though the patients showed severe manifestations, they were initially misdiagnosed, resulting in 2 persons finally died from TETS and FAA poisoning in homicide cases...

Avian scavengers that typically include game birds and mammals in their diets are at risk of lead poisoning from ingestion of carcasses with fragmented or residual lead ammunition that is used in hunting. Thus, lead may be one of the threats that the griffon vulture ( Gyps fulvus ) faces in the Iberian Peninsula and particularly in Portugal, where their conservation status is considered to be near-threatened. This is the first report that details 3 cases of lead poisoning, associated with the ingestion of lead shot, in adult female griffon vultures found in the Iberian Peninsula...

The chirality-selective synthesis of relatively large (diameter > 1 nm) single-walled carbon nanotubes (SWCNTs) is of great interest for a variety of practical applications, but only a few catalysts are available so far. Previous studies suggested that S (compounds) can enhance the chirality-selectivity of Co catalysts in SWCNT synthesis, however, the mechanism behind is not fully understood, and no tailorable methodology has yet been developed. Here, we demonstrate a facile approach to achieve the chirality-selective synthesis of SWCNTs by the sulfidation-based poisoning of silica-supported Co catalysts using a mixture of H2S and H2...

Lead toxicity in adults is characterized by nonspecific symptoms of abdominal pain, vomiting, constipation, fatigue, and weight loss. We present a case of severe lead toxicity that developed subacutely, causing quadriparesis 9 years after a gunshot wound with retained bullet fragments. The onset of symptoms may have been related to the development of a pseudocyst. The long interval between the gunshot wound and the onset of symptoms contributed to a delay in suspecting that the retained bullet was a source of lead toxicity...

CONTEXT: No kinetic models presently exist which simulate the effect of chelation therapy on lead blood concentrations in lead poisoning. OBJECTIVE: Our aim was to develop a kinetic model that describes the kinetics of dimercaptosuccinic acid (DMSA; succimer), a commonly used chelating agent, that could be used in developing a lead chelating model. MATERIAL AND METHODS: This was a kinetic modelling study. We used a two-compartment model, with a non-systemic gastrointestinal compartment (gut lumen) and the whole body as one systemic compartment...

Cadmium and lead were measured in liver and kidney samples of 242 Japanese black bears (Ursus thibetanus japonicus) captured from 1999 to 2014 from two local populations in Japan. The median concentration of cadmium was 0.54 (mean: 0.80) mg/kg-w.w. in liver and 7.7 (mean: 11.8) mg/kg-w.w. in kidney. The median concentration of lead was 0.24 (mean: 0.40) and 0.21 (mean: 0.32) mg/kg-w.w. in liver and kidney, respectively. Bears in the Kita-ou local population had higher concentrations of cadmium and lead than those in the Kitakami Highlands local population...
