Toxic objects have been introduced to avoid trap rules, especially in (purely) catalytic P systems. No toxic object is allowed to stay idle during a valid derivation in a P system with toxic objects. In this paper we consider special variants of toxic P systems where the set of toxic objects is predefined – either by requiring all objects to be toxic or all catalysts to be toxic or all objects ...
ETHNOPHARMACOLOGICAL RELEVANCE The stem bark of Garcinia livingstonei is used traditionally as a skin lightening agent. AIM OF THE STUDY To isolate and identify compounds responsible for the observed skin lightening activity of Garcinia livingstonei and to evaluate their cytotoxicity. MATERIALS AND METHODS Constituents of the stem bark and fruits of Garcinia livingstonei were isolated using...
Amyloids were first identified in association with amyloidoses, human diseases in which proteins and peptides misfold into amyloid fibrils. Subsequent studies have identified an array of functional amyloid fibrils that perform physiological roles in humans. Given the potential for the production of toxic species in amyloid assembly reactions, it is remarkable that cells can produce these functi...
PURPOSE We have shown that cerium oxide nanoparticles (nanoceria), with unique characteristics and catalytic activities, are retained in the retina for more than 1 year after a single intravitreal injection and can be potentially used for the treatment of a variety of eye diseases. The objective of this study is to determine whether the retention of nanoceria in the eye causes inflammation or a...
Affective disorder and arthritis are both common conditions, and drugs form the mainstay of treatment for both illnesses. Despite the large variety of agents used to treat both disorders, toxic interactions between psychotropic and the anti-rheumatic drugs seem uncommon. One combination that has recently attracted some attention is lithium toxicity precipitated by certain non-steroidal anti-inf...
