Start-up Uses New Incubator Space To Commercialize UCLA Technology
UCLA has opened a new technology incubation space within the California NanoSystems Institute (CNSI) to Matrix Sensors Inc., a start-up that"s developing multichannel gas and biological sensor systems based on technology developed jointly by UCLA and Stanford University researchers.

Fate Therapeutics To Present Data On Stimulation Of Osteogenic Activity Using Small Molecule Modulators Of Wnt Pathway
Fate Therapeutics, Inc. announced the presentation of data from its research on small molecule modulators of the Wnt pathway for osteo-regeneration at the 7th Annual Meeting of the International Society for Stem Cell Research (ISSCR) in Barcelona, Spain. In its findings, the Company demonstrated that selected Wnt activators induce the differentiation of mesenchymal stem cells to mature, bone-forming osteoblasts. The study highlights the potential for using small molecule Wnt activators as osteogenic agents. Because osteogenic agents stimulate positive bone growth, they may offer an improved course of action in clinical settings ranging from orthopedics to osteoporosis as compared to current medications aimed at preventing bone decay.

Simple Measures May Prevent Transmission Of Stomach Ulcer Bacteria
The stomach ulcer bacterium Helicobacter pylori is not transmitted through drinking water as previously thought, but rather through vomit and possibly faeces. This is shown in a thesis at the Sahlgrenska Academy, University of Gothenburg, Sweden. It is therefore possible to prevent the spread of the bacterium in developing countries through some fairly simple measures.

Radiation Dose Drastically Reduced During Whole Chest MDCT

Emergency physicians who evaluate patients with non-specific chest pain using whole chest multi-detector CT (MDCT) combined with retrospective electrocardiogram (ECG) gating can reduce the patient radiation dose by 71% using MDCT combined with prospective ECG triggering instead, according to a study performed at the University of Washington School of Medicine, Seattle, WA. Prospective ECG triggering enables the CT scanner to monitor the ECG signal of several heart beats in real time and turns the radiation beam on only during alternate beats; retrospective ECG gating also monitors the ECG signal of heartbeats but turns the radiation beam on throughout several consecutive beats, thus delivering more radiation. Seventy-two emergency department patients with non-specific chest pain were referred for MDCT of the whole chest. A total of 41 patients were scanned using retrospective gating and 31 were scanned using prospective triggering. "The average radiation dose delivered with retrospective gating was approximately 32 mSv; the average radiation dose delivered with prospective triggering was 9 mSv," said William P. Shuman, MD, lead author of the study. In addition, image quality was slightly better with prospective triggering. "As our study suggests, patients benefit from MDCT scans using ECG triggering because it delivers a much lower radiation dose opening the utility of CT to more patients. This lower dose is particularly useful when non-specific indications suggest scanning of the whole chest, such as in the "triple rule-out." Emergency rooms face severe congestion and cost constraints in today"s world, plus a need for accurate, swift diagnosis. Lower dose, high image quality ECG triggered CT will help significantly on all of those fronts," said Dr. Shuman. This study appears in the June issue of the American Journal of Roentgenology. About ARRS The American Roentgen Ray Society (ARRS) was founded in 1900 and is the oldest radiology society in the United States. Its monthly journal, the American Journal of Roentgenology, began publication in 1906. Radiologists from all over the world attend the ARRS annual meeting to participate in instructional courses, scientific paper presentations and scientific and commercial exhibits related to the field of radiology. The Society is named after the first Nobel Laureate in Physics, Wilhelm Rē¶entgen, who discovered the x-ray in 1895. American Roentgen Ray Society (ARRS)
