Protoporphyrin IX (PPIX) fluorescence-guided brain tumor resection, using 5-aminolevulinic acid (5-ALA), is among the most valuable tools for determining tumor removal area. However, PPIX fluorescence is not necessarily achieved during an operation visually even when 5-ALA is used, and we do not know until tumor exposure to the excitation light of the ultraviolet region whether PPIX fluorescence has been achieved. When a particular biopsy and frozen section diagnosis is made, the reason for lack of PPIX fluorescence in the tissue cannot be judged. We do not know whether the tumor fails to fluoresce or no fluorescence is seen because it is not the main body of the tumor. We investigated whether the presence or absence of tumor fluorescence could be predicted by examining urinary porphyrin before surgery, at the time of intraoperative fluorescence diagnosis using 5-ALA. The urine of brain tumor patients 2 hours after 5-ALA administration was irradiated with a 405 ± 1 nm laser light. The patients were divided into a fluorescent urine group and negative fluorescent urine group. Red fluorescence was observed in response to the 405 ± 1 nm laser beam for all tumors in the fluorescent urine group. Clear red fluorescence was not observed even with 405 ± 1 nm laser beam irradiation in any tumors in the negative fluorescent urine group. Preoperative prediction of the intraoperative fluorescence of PPIX can be achieved by observation of urine 2 hours after 5-ALA administration with exposure to a 405 ± 1 nm laser light.

The aim of this retrospective study was to investigate the efficacy of saireito for bilateral chronic subdural hematomas (B-CSDH). Between April 2006 and March 2010, a total of 18 patients undergoing unilateral burr hole drainage for B-CSDH took part in a controlled clinical study. Postoperative status of the nonsurgical side was subsequently evaluated, with (n = 10) and without (n = 8) saireito administration. Two in the saireito-treated group patients and four in the control group patients ultimately required contralateral surgical intervention. The remainder, including eight saireito-treated hematomas, resolved without further surgery, generally within eight weeks of the surgical side procedure. However, two of the four resolving control lesions took longer to regress. The hydragogue and anti-inflammatory/steroid-evoking properties ascribed to saireito may facilitate hematoma resolution. After unilateral surgery for B-CSDH, saireito administration may prevent symptomatic deterioration of a contralateral low-density CSDH, preempting subsequent surgery.

The objective of this study was to examine the effects of addition of inoculant to high-nitrogen (N) fertilized timothy on fermentation, nutritive value, and feed intake of silage. The silage of timothy cultivated with a N fertilizer rate at two levels (high level (H), standard level (S)) was prepared with (SI, HI) or without (SC, HC) an inoculants. The CP content of H increased by 38 g·kg-1 DM compared with that of S, and the WSC and ADF contents decreased compared with those of S. Regarding the fermentation of silage, the pH and NH3-N ratio was significantly lower in the silage with inoculant (SI and HI), showing improvement of the fermentation compared with those of the silage without the addition (SC and HC). The CP content was significantly higher in HC and HI than in SC and SI, and the NDF content was the lowest in HI among the four treatments. The CP digestibility of HC and HI was significantly higher than those of SC and SI. The EE digestibility of SI was significantly higher than that of SC, and that of HI was significantly higher than that of HC. The DCP contents were significantly higher in HC and HI than in SC and SI. The TDN content was the lowest in SC and highest in HI. The DCP intakes of HC and HI were significantly higher than those of SC and SI. When the N fertilizer rate was increased, the DCP content and DCP intake of the silage increased, and the addition of inoculant improved the fermentation and increased the TDN content.

This study aims, first, to examine the limit for tolerance to lower salinity by an oceanic sea skater, Halobates micans, and , second, to make it clear whether exclusively fresh water Halobatinae species, Metrocoris histrio has salinity tolerance. Adults of H. micans were collected using Neuston Net from the starboard side of R/V MIRAI on a fixed station at 8°S, 80°E, whereas those of M. histrio were collected from a small pond filled with a spring fresh water in Kochi (33°N, 133°E), Japan. Time in survival was measured in starved condition under several salinity conditions: 0‰, 2‰, 4‰, 6‰, 8‰, 9‰ and 10‰ for H. micans;0‰, 5‰, 10‰, 12.5‰, 15‰ for M. histrio. Half of adults were in coma due to lower salinity under 10‰ and time in survival was less than 10 hours under less than 4‰ for H. micans. Time in survival was half at 5‰ of 80 hours on average at 0‰ as a control and less than 10 hours at 10‰ or higher salinity for M. histrio. Relatively flexible osmo-regulation ability by H. micans would be related to wide variety of salinity condition of surface oceanic water, whereas very limited tolerance even to lower salinity of 5‰ may be permitted by the no chances to be exposed to brackish water in natural habitats of M. histrio. This study showed that salinity tolerance of Halobatinae species would reflect, directly, the salinity condition of their habitats.

Robot technology is expected to reduce the burden of medical professionals, a concern in the super-aged society. The aim of this article is to determine the intermediary roles of Public Health Nurses (PHNs) in using Communication Robots (CRs) in Community Health care. It is necessary to consider who will manage, and how to draw lines of responsibility when a problem occurs when using robots in the future. Regarding the mediator or intermediary role of PHNs in the use of CRs, PHNs are expected to be cognizant of varieties of robots for use with persons of diverse ages and health levels, as well as of robot performances. As one of the community healthcare workers who service the elderly living in the community, the role of PHNs as mediators or intermediaries is to pay attention to ethical and moral issues while working with CRs to manage the health of the community. Lack of understanding of the intermediary role might create possible ethico-moral issues in the future. Therefore, it is critical for PHNs to understand their role as intermediaries. In doing so, it is expected that older people at home will be able to live peaceful lives, as well as be physically and mentally healthy.

The objective of this study was to examine the effects of potassium fertilizer (standard (S) and high (H) levels) on water-soluble carbohydrate (WSC) content of timothy (Phleum pratense L.), silage fermentation, nutritive values, and nutrient intake. The silage treatments were as follows: S level without inoculant (SC), S level plus inoculant (SI), H level without inoculant (HC), and H level plus inoculant (HI). The K content was increased by 14.5% in timothy grown with the H level compared with the S level. The WSC contents of the S and H treatments were 75.9 and 66.1 g·kg-1 dry matter (DM), respectively. The silage fermentation quality was low with both SC and HC treatments. The addition of inoculant significantly improved the fermentation quality in SI and HI treatments. The addition increased the DM and organic matter digestibilities of silage. The total digestible nutrient (TDN) content of silage was highest with the HI treatment. The DM, TDN, and digestible energy intakes with the SI and HI treatments were improved compared with the SC and HC treatments, respectively. This study demonstrated negligible effects of K fertilizer levels and significant effects of the lactic acid bacteria inoculant on the fermentation quality, nutritive values, and feed intake of silage.
