Antiobese effects of novel saponins from edible seeds of Japanese horse chestnut (Aesculus turbinata BLUME) after treatment with wood ashes     

Kimura H  Ogawa S  Katsube T  Jisaka M  Yokota K 《Journal of agricultural and food chemistry》2008,56(12):4783-4788

Recently, we have identified novel saponins from edible seeds of Japanese horse chestnut ( Aesculus turbinata BLUME) after processing the natural seeds with wood ashes to remove bitterness. We attempted to determine anti-obesity effects of those saponins from edible seeds as well as natural seeds. The purified individual components of saponins from natural and edible seeds inhibited pancreatic lipase in vitro. The potency was in the order of escins > desacylescins > deacetylescins. Escins Ib and IIb as well as deacetylescins Ib and IIb with the angeloyl moiety were more potent than the corresponding Ia and IIa series with the tigloyl moiety. Moreover, in vivo anti-obesity effects of the saponin fractions were monitored for 8 weeks in mice fed high-fat diets. Saponin fractions from both seeds significantly attenuated the elevation in body weight, the mass of peritoneal adipose tissues, and plasma triacylglycerol, which was accompanied by higher contents of undigested fats in feces without changes in food intake, indicating the effective inhibition of fat digestion in vivo. Taken together, saponin fractions including desacylescins and deacetylescins from edible seeds are potentially useful for the development of nutraceutical foods with anti-obesity effects and more attenuated bitter taste.  相似文献   

Effectiveness of tori-lines for further reduction of incidental catch of seabirds in pelagic longline fisheries     

Kosuke Yokota  Hiroshi Minami  Masashi Kiyota 《Fisheries Science》2011,77(4):479-485

To improve the performance of tori-lines (bird-scaring lines) in reducing incidental catch of large seabirds (albatrosses and giant petrels) in the pelagic longline fishery, we analyzed factors affecting the performance of tori-lines based on data collected by Japanese scientific observers in the southern bluefin tuna Thunnus maccoyii fishery from 2002 to 2005. We classified the variety of tori-lines by the main tori-line length and the streamer type. Two types of streamers were identified: type A, several long streamers made of nylon cord attached to the main tori-line by metal swivels; type B, many short streamers made of polypropylene packing bands braided into the main tori-line. In a model analysis, we found that the main tori-line length was an important factor affecting tori-line performance, and the two types of streamers had similar effectiveness. Since the light type B streamer has the advantage of practical feasibility, this type can be another option for use in tori-lines if used with a main tori-line of sufficient length.  相似文献   

Scleroderris Canker of Todo-Fir in Hokkaido,Northern Japan     

S. Yokota  T. Uozumi  S. Matsuzaki 《Forest Pathology》1975,5(6):356-366

Disease development and severity of Scleroderris canker of Todo-fir in Hokkaido vary according to forest type. Todo-fir under a canopy of deciduous species are almost free from canker, whereas in the open they are severely attacked. The situations are described with relation to environmental conditions associated with canker development.  相似文献   

Effect of thin twine on gill net size-selectivity analyzed with the direct estimation method     

Kosuke Yokota  Yasuzumi Fujimori  Daisuke Shiode  Tadashi Tokai 《Fisheries Science》2001,67(5):851-856

ABSTRACT: To analyze the effect of thin twine on gill net size selectivity, a series of fishing experiments using gill nets of two twine thicknesses (no. 0.8 of 0.16 mm diameter and no. 3 of 0.28 mm diameter) and three nominal mesh sizes (41 mm, 46 mm and 51 mm) was conducted in outdoor water tanks containing a rainbow trout ( Oncorhynchus mykiss ) population of known size frequency. For nets of the same nominal mesh size, mesh openings of the no. 0.8 twine nets were approximately 2 mm larger than those of the no. 3 twine nets. The effects of both mesh opening and twine thickness are combined in the conventional analysis with the selectivity curve against fish length. Selectivity against the ratio of fish girth to mesh perimeter was calculated to avoid the direct effect of changes in mesh openings due to twine diameter at the same nominal mesh size. Results demonstrated that the thinner twine gill net was more likely to capture rainbow trout of smaller girth than the mesh perimeter. Fish with girths smaller than the mesh perimeter were often retained by the net with its body tangled by the thinner twine, possibly due to the increased flexibility of the thinner twine.  相似文献   

Three-dimensional reconstruction of the equine ovary   总被引：1，自引：0，他引：1  

Kimura J  Hirano Y  Takemoto S  Nambo Y  Ishinazaka T  Himeno R  Mishima T  Tsumagari S  Yokota H 《Anatomia, histologia, embryologia》2005,34(1):48-51

The equine ovary has a very unique structure in terms of its extreme large size, the presence of the ovulation fossa and the inverted location of its cortex and medulla. In the previous study, it was recognized that the application of three-dimensional internal structure microscopy (3D-ISM) to observe the mare ovary is very effective. Three-dimensional reconstruction of serially sliced images made by 3D-ISM was successful in this study with the aid of the sophisticated image processing technique. The rotation of the reconstructed ovary has been carried out with and without the application of the transparency technique in the ovarian stromal region. The spatial localization of follicles and corpus luteum was clearly visualized by rotating the reconstructed image of the ovary. The extraction of the images of follicles and corpus luteum was also available and gave a quantifiable understanding of their structure.  相似文献   

Aspergillus fumigatus infection in an ostrich (Struthio camelus)     

Yokota T  Shibahara T  Wada Y  Hiraki R  Ishikawa Y  Kadota K 《The Journal of veterinary medical science / the Japanese Society of Veterinary Science》2004,66(2):201-204

An 11-month-old female ostrich (Struthio camelus) had become gradually emaciated over a 2-week period and subsequently died. Necropsy revealed white to green mold growth on the walls of caseous thickened air sac membranes and multiple white necrotic foci in the lungs and liver. Histologically, the multiple exudative, necrotic and granulomatous lesions were compatible with mycotic infection in the air sacs and lungs, and hyphae positively reacted with a monoclonal antibody (Mab-WF-AF-1) to Aspergillus fumigatus wall fractions. Multifocal hepatic necrosis was also found, and several spores were observed in the blood vessels. Fungal culture of these lesions yielded pure growth of A. fumigatus. This is an established case of fatal A. fumigatus infection in an ostrich reared in Japan.  相似文献
