The prevalence of Helicobacter pylori (a type of bacteria associated with gastrointestinal disorders) is high among patients about to undergo weight loss surgery, and treatment to eradicate the bacterial infection before surgery may be beneficial, according to an article in the October issue of The Archives of Surgery, one of the JAMA/Archives journals.
The number of obese and morbidly obese Americans is steadily increasing, according to background information in the article. It is estimated that more than 30 percent of the U.S. population has a body mass index (BMI) over 30 (obese), and five percent of the U.S. population has a BMI over 40, resulting in a increased demand for weight loss surgery, including gastric bypass surgery (surgery that results in food bypassing much of the intestinal tract). Twenty to 50 percent of people living in industrialized countries are infected with H pylori, which is believed to be involved in gastroduodenal ulcer disease (a gastrointestinal tract disease characterized by ulcers in the stomach and upper intestinal tract, or foregut), in addition to gastric cancer, according to the article. The role of H pylori after gastric bypass surgery is unknown.
Archana Ramaswamy, M.D., from Emory University, School of Medicine, Atlanta, and colleagues examined 99 patients between September 2001 and September 2002 as part of an evaluation for weight loss surgery. The patients (16 men and 83 women; average age 40 years; average BMI, 48) underwent routine testing before their weight loss surgeries, including testing for the presence of H pylori.

Highly precise wiring in the Cerebral Cortex
21.09.2017 | Max-Planck-Institut für Hirnforschung
Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
