There is considerable interest in means for predicting reactivity hazard potential from chemical structure. Such means are intended to provide measures of the likelihood that a given chemical composition can undergo rapid self-reaction, i.e., that it can detonate or deflagrate. The means to be discussed are most useful in predicting behavior under unconfined conditions. As they are computationa...

Car seat heaters have gained popularity in America and worldwide. They offer comfort by heating the sitting surface to a soothing temperature. Several cases of heating-element malfunction resulted in burn injuries and have triggered recalls of thousands of cars by the manufacturers. We present a case of a 48-year-old patient with long-standing paraplegia who sustained third-degree burns on his ...

BACKGROUND The only treatment for celiac disease (CD) is a gluten-free diet (GFD). However, there is interest among patients in a medical therapy to replace or help with a GFD. Therapies include gluten-degrading enzymes (glutenases). There are glutenases available marketed as dietary supplements that have not been demonstrated to digest the toxic epitopes of gluten. METHODS We investigated th...

Melnick (1) recently suggested that because peroxisome proliferation is not established as an obligatory step in the carcinogenicity of peroxisome proliferators (PPs), the proposal that the peroxisome proliferator di(2-ethylhexyl)phthalate (DEHP) poses no carcinogenic risk to humans (2) due to species differences in peroxisome proliferation should be viewed as an unvalidated hypothesis (1). In ...

Background: Laboratory activities must be planned and organized carefully because of the danger they may cause. The purpose of this study was to assess students’ awareness and comprehension of chemical hazard warning signs at the Departments of Chemistry of Razi University, Kermanshah, Iran. Materials and Methods: This descriptive study was carried out to assess students’ awarene...

Any defects in street trees may cause injuries to human, vehicles and buildings. This research was investigated in the Babol city, Mazandaran province, in the northern state of Iran.Used the perfect inventory methods and measured the diameter at breathe height (DBH), height and hazardous criteria (dead woods, cracks or seams, decay, wound or cankers, root problems, weak branch unions and skew f...
