Mutagenicity of nitrosated food items.

Several food items, commonly consumed in South India, after nitrite treatment under simulated gastric conditions were found to be mutagenic in Salmonella typhimurium tester strain TA 100. Dichloromethane extracts containing the volatile nitroso compounds and ethyl-acetate extracts with the non-volatile nitroso compounds of some of the food items exhibited mutagenicity.     

PsychTable.org: The Taxonomy of Human Evolved Psychological Adaptations

We announce the launch of , a collaborative web-based project devoted to classifying and evaluating evolved psychological adaptations (EPAs), geared toward researchers, educators, students, and the general public. The website works by aggregating citations which support or challenge the existence of each purported EPA, using a mathematical algorithm to assign an evidentiary strength score to each, and generating a table which represents the current but ever-changing state of the empirical evidence. Citations are added and assigned evaluative ratings by both general users and an international community of expert contributors; as such, the content of the site will represent the consensus of the scientific community and new research opportunities. PsychTable has features for achieving empirical meta-goals such as quality control, hypothesis testing, cross-disciplinary collaboration, and didactic utility. Additionally, PsychTable will help adjudicate arguments within the field by providing a one-stop resource to display which proposed EPAs have strong empirical support and which others are relatively lacking in evidence.     

Mycosis fungoides. The importance of pulmonary cytology in the diagnosis of a case with systemic involvement

A patient with cutaneous mycosis fungoides developed pulmonary lesions while under radiation therapy. Bronchial cytologic specimens demonstrated malignant lymphocytes, which open lung biopsy confirmed to be mycosis cells. We believe this is the first report to document pulmonary involvement of mycosis fungoides by the use of bronchial cytology.     

Presence of polycyclic aromatic hydrocarbons in some South Indian food components.

South Indian food dishes, comprising several deep fried items have been proved to be mutagenic. Polycyclic aromatic hydrocarbons (PAHs) such as, benzo(a)pyrene, chrysene and dibenzanthracene, which are potent and proven carcinogens have been identified and quantified in several of the commonly consumed South Indian food dishes and food components. Most of the pyrolysed items contained PAHs in appreciable quantities. PAHs were detected in significant levels in salted, sundried and oil fried vegetables and fishes. Some of the raw and uncooked food components also revealed the presence of PAHs.
