This review report represents an overview of research and development on medical hyperspectral imaging technology and its *** imaging technology is attracting attention as a new imaging modality for medical applications,especially in disease diagnosis and image-guided *** the recent advances in imaging,this technology provides an opportunity for twodimensional mapping of oxygen saturation(sato2)of blood with high accuracy,spatial spectral imaging,and its analysis and provides detection and diagnostic information about the tissue physiology and *** imaging also provides information about tissue oxygenation,perfusion,and potential function during *** algorithm has been examined,and indication of accurate map of relative hemoglobin concentration and sato2 can be indicated with preferable resolution and frame *** technology is expected to provide promising biomedical information in practical *** studies suggested that blood flow and sato2 are associated with gastrointestinal disorders,particularly malignant tumor *** use and analysis of spectroscopic images are expected to potentially play a role in the detection and diagnosis of these diseases.

＜正＞ To obtain high quality crystals of protein, a number of crystallization trials have been carried out under a microgravity circumstance. However, a success rate has been quite low, and better crystals were obtained only in the trials less than 30 %. Thus, it needs to reveal the mechanism of the growth of high quality prtein crystals.

Familial pancreatic cancer (FPC) is broadly defined as two first-degree-relatives with pancreatic cancer (PC) and accounts for 4%-10% of PC. Several genetic syndromes, including Peutz-Jeghers syndrome, hereditary pancreatitis, hereditary breast-ovarian cancer syndrome(HBOC), Lynch syndrome, and familial adenomatous polyposis (FAP), also have increased risks of PC, but the narrowest definition of FPC excludes these known syndromes. When compared with other familial tumors, proven genetic alterations are limited to a small proportion (Caucasian) and a younger onset are common also in FPC. In European countries, "anticipation" is reported in FPC families, as with other hereditary syndromes; a trend toward younger age and worse prognosis is recognized in the late years. The resected pancreases of FPC kindred often show multiple pancreatic intraepithelial neoplasia (Pan IN) foci, with various K-ras mutations, similar to colorectal polyposis seen in the FAP patients. As with HBOC patients, a patient who is a BRCA mutation carrier with unresectable pancreatic cancer (accounting for 0%-19% of FPC patients) demonstrated better outcome following platinum and Poly (ADP-ribose) polymerase inhibitor treatment. Western countries have established FPC registries since the 1990 s and several surveillance projects for highrisk individuals are now ongoing to detect early PCs. Improvement in lifestyle habits, including non-smoking, is recommended for individuals at risk. In Japan, the FPC study group was initiated in 2013 and the Japanese FPC registry was established in 2014 by the Japan Pancreas Society.
