Thin‐film field‐effect transistors showing n‐ and p‐type conduction under different bias conditions are produced from solution‐processable ambipolar blends of thieno[2,3‐b]thiophene terthiophene polymer and phenyl C61 butyric acid methyl ester (see Figure). Balanced charge transport in this blend is achieved by treating the insulator interface with alkyl‐chain silanes. Complementary‐like inverters have been fabricated on a single substrate, showing a maximum gain of 65.
Mammary hamartomas were reported in 0.7% of all benign tumors of the female breast. Histologically breast hamartomas contain lobular breast tissue with various degrees of fibrous, fibrocystic, and adipose tissue. Rare types include muscular (myoid) and cartilage (chondroid) hamartomas. We report a case of muscular hamartoma in a man. A 36year-old man was admitted to the psychiatric unit with the diagnosis of schizophrenia. The patient complained of a slowly growing mass in his left breast. He denied any discharge from the nipple, but he complained of itching. A 2 cm ϫ 3 cm nontender mass was palpable. There was no evidence of axillary lymphadenopathy. A needle aspiration was nondiagnostic. The excisional biopsy specimen revealed fatty tissue which was edematous and hemorrhagic. Microscopically it showed multiple bundles of muscles organized randomly. Myoid hamartoma was the diagnosis. Mammary hamartoma is considered a female tumor exclusively. Myoid hamartoma has been reported previously in 25 women. We report a myoid hamartoma in a man and, to our knowledge, it is the first and only such case to be reported.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
