Proteomic analysis of natural photoheterotrophic mixed consortium for biohydrogen production under nongrowing conditions.

A biohydrogen and polyhydroxyalkanoates(PHA)-producing natural photoheterotrophic mixed culture composed mainly by Rhodopseudomonas palustris and Clostridium sp was studied by a proteomic analysis under non-growth conditions (nitrogen-absence and organic acids). Proteins in C. pasteurianum were upregulated, particularly those related to stress response.

Fishbone perforation of the stomach into the lesser sac and pancreas with abscess, a fishy business.

Ingestion of foreign bodies is common in critical practice. Thankfully, most of these objects will pass without complications; however, sharp and metallic objects can cause severe complications like ulcers and perforation. Perforation of the gastrointestinal tract is rare; however, once it happens, prompt treatment is needed to prevent dreadful complications.

Broadband mode exchanger based on subwavelength Y-junctions.

Multimode silicon photonics, leveraging mode-division multiplexing technologies, offers significant potential to increase capacity of large-scale multiprocessing systems for on-chip optical interconnects. These technologies have implications not only for telecom and datacom applications, but also for cutting-edge fields such as quantum and nonlinear photonics. Thus, the development of compact, low-loss and low-crosstalk multimode devices, in particular mode exchangers, is crucial for effective on-chip mode manipulation.
