Two case studies from Japan presented at the 72nd Annual Meeting of the American College of Gastroenterology point to a potential health problem in the United States, as more Americans consume raw fish in the form of sushi and sashimi. Anisakiasis (round worm) is a human parasitic infection caused by the consumption of raw or undercooked seafood containing Anisakis larvae.
Consumers should be aware that while larvae for the parasitic worm Anisakis cannot survive in a human host, the ingested larvae can produce severe intestinal problems warranting a visit to the emergency room.
When ingested by humans, the larvae attach themselves to the tissues lining the stomach and intestines, resulting in sudden abdominal pain, nausea, vomiting, and diarrhea. Since the larvae cannot survive in humans and eventually die, intestinal anisakiasis usually resolves on its own.
Researchers in Japan examined two cases of intestinal anisakiasis presenting as an obstruction of the small intestine. In each case, both patients, ages 64 and 70, were rushed to the emergency room with sudden abdominal pain and vomiting after eating raw sardines as sashimi two days earlier. The diagnosis of anisakiasis in the stomach can easily be confirmed by endoscopy. However, small intestinal anisakiasis is difficult to diagnose. Both patients had abdominal X-rays showed air-fluid levels suggesting a small intestinal obstruction. Using a multidetector-row computed tomography (MDCT), doctors obtained high quality images of the small bowel, and found the intestinal blockage was caused by the presence of Anisakis larvae. Fluid replacement and resting immediately relieved the patients’ symptoms.
Because the symptoms of anisakiasis can mimic other gastrointestinal diseases, it might potentially be misdiagnosed as appendicitis, acute abdomen (peritonitis) or stomach ulcers. According to Mashahiro Matshushita, MD of Haibara General Hospital, “Anisakiasis should be considered in the differential diagnosis of small intestinal obstruction.”

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
