A one-pot synthesis of 2,6-dibromodithieno[3,2-b;2',3'-d]thiophene (dibromo-DTT, 4) was developed. A key step was bromodecarboxylation of DTT-2,6-dicarboxylic acid, obtained by saponification of the diester 1. The donor-acceptor dye DAHTDTT (13), based on a central 2,6-bis[2'-(3'-hexylthienyl)]dithieno[3,2-b;2',3'-d]thiophene core (9), was prepared and incorporated in a dye-sensitized solar cel...

In vivo skin is under tension on the body. However, gold standard of research model systems are ex explants, prepared from “relaxed” tissue obtained patients undergoing abdominoplasty surgeries. This maintains almost all properties native skin, but conventional culturing methods do not maintain in tension. our approach, explants cultured at air-liquid interface stretched directions, thus provid...

The primo vascular system (PVS) is being established as a circulatory system that corresponds to acupuncture meridians. There have been two critical questions in making the PVS accepted as a novel liquid flowing system. The first one was directly to show the flow of liquid in PVS and the second one was to explain why it was not observed in the conventional histological study of animal tissues. ...

This study was carried out to determine distribution and heterogeneity of mast cells in the digestive tract of the both chicken and quail. Ten Leghorn chickens and ten Japan quails were use during the investigation. Having been sacrified by decapitation, the chickens and quails’ tongue, crop, esophagus, proventriculus, gizzard, duodenum, jejunum, ileum, caecum and colon tissue samples were take...
