Light-Mediated Toxicity of Porphyrin-Like Pigments from a Marine Polychaeta

Supramolecular Electronics Derived from Porphyrin-like Pigments

The field of organic based electronics has become a blossoming area of intensive study during the past decade. The promise of a cheaper and easier-to-process alternative to inorganic based semiconductor materials makes these materials highly desirable. Additionally, organic based electronics can be made into flexible structures, allowing for the fabrication of visual displays that can be folded...

Prodigiosin-like pigments from Actinomadura (Nocardia) pelletieri.

gradual erasure of subjectivity: a study of samuel beckett’s trilogy in the light of postmodernism

ساموئل بکت بیشتر از هر نویسنده دیگری در نیم? دوم قرن بیستم با گفتارش زمان? ما را به آستان? از هم پاشیدگی کشانده است، آستانه ای که در آن مدرنیته با سرانجام گریزان اما غیرقابل اجتناب خود مواجه می شود. در این تحقیق روی مفهوم فردیت و محو آن در دوران پسامدرن تاکید شده و در طی آن سعی شده است که فردیت مدرن و پسامدرن در رمان های سه گانه بکت بررسی گردد. تحقیق حاضر یک بررسی کتابخانه ای و کیفی بر روی سه ر...

Bioactive Pigments from Marine Bacteria: Applications and Physiological Roles

Research into natural products from the marine environment, including microorganisms, has rapidly increased over the past two decades. Despite the enormous difficulty in isolating and harvesting marine bacteria, microbial metabolites are increasingly attractive to science because of their broad-ranging pharmacological activities, especially those with unique color pigments. This current review ...

Marine biodiversity of Costa Rica: class Polychaeta (Annelida).

Three hundred and thirty two species of polychaetes belonging to 50 families are reported for Costa Rica based on previously published reports. In a few families, available material was re-examined and appropriate changes in species identifications were made. Only three species, (Glycera oxycephala Ehlers, 1887; Hemipodia pustulata (Friedrich 1956); and Scolepis (Scolepis) squamata (Miller, 180...
