Currently, the superfamily Axioidea Huxley, 1879 includes nine families (Sakai, 2011). However, recent examination of material from the Gulf of Nicoya, Costa Rica, Pacific side, presented the occurrence of a new species, Neoaxius nicoyaensis gen. et sp. Nov. The deviant morphology of the genital organs of this new species can nowhere be observed in any of the known genera of the families included in the Axioidea. This necessitated the author to establish a new family, Neoaxiidae fam. nov., based on the new genus Neoaxius gen. nov. The new family is safely included in the Axioidea as a tenth member of that superfamily. © Koninklijke Brill NV, Leiden, 2017.

In the present paper, two new species, Acanthaxius kashimaensis sp. nov. and A. pseudopolyacanthus sp. nov., are described and a revised key to the species of the genus Acanthaxius Sakai &De Saint Laurent, 1989 is presented. In addition, Balssaxius habereri (Balss, 1913) and Boasaxius princeps (Boas, 1880) of the family Axiidae Huxley, 1879, Neaxius glyptocercus (Von Martens, 1869) of the family Strahlaxiidae Poore, 1994, together with Trypaea truncata (Giard &Bonnier, 1890) of the family Callianassidae Dana, 1852, and two species, Calliax lobata (De Gaillande &Lagardère, 1966) and Calliaxina punica (De Saint Laurent &Manning, 1982), of the family Eucalliacidae Manning &Felder, 1991 [sensu Sakai, 2011], are commented upon. The descriptions given herein result from the examination of specimens collected from Ise-Shima, Mie Prefecture and Ôfunato-City, Iwate Prefecture, as well as from Iriomote Island, Ryukyu Islands, Japan, and from material collected from Salamis, Saronikos Gulf, Greece, and the Palinuro Seamount, southern Tyrrhenian Sea, Italy. © 2017 Koninklijke Brill NV, Leiden.

Mitten crabs (Brachyura, Varunidae, Varuninae) are currently classified into six species belonging to three genera: Eriocheir De Haan, 1835, Neoeriocheir T. Sakai, 1983, and Platyeriocheir Ng, Guo & Ng, 1999, i.e., Eriocheir japonica (De Haan, 1835), E. hepuensis Dai, 1991, E. ogasawaraensis Komai, Yamasaki, Kobayashi, Yamamoto & Watanabe, 2006, and E. sinensis H. Milne Edwards, 1853; Neoeriocheir leptognatha (Rathbun, 1913); and Platyeriocheir formosa (Chan, Hung & Yu, 1995). The results of the present study, however, indicate a reclassification into four genera including one new genus, together lodging seven species, including one new species, and with an eighth currently nameless species remaining as a species inquirenda, as follows: Eriocheir De Haan, 1835, with E. japonica (De Haan, 1835) and E. ogasawaraensis Komai et al., 2006; Paraeriocheir gen. nov., with P. hepuensis (Dai, 1991) and P. sinensis (H. Milne Edwards, 1853); Platyeriocheir Ng et al., 1999, with P. formosa (Chan et al., 1995) and P. guangdonga sp. nov.; and Neoeriocheir T. Sakai, 1983, with N. leptognatha (Rathbun, 1913); under the prevailing circumstances, the species now indicated as Eriocheir sp. [= Eriocheir recta sensu Stimpson, 1858] is to be considered a species inquirenda. © 2013 Koninklijke Brill NV, Leiden, The Netherlands.

Recently, a new species of the genus Ctenocheloides Anker, 2010, viz., Ctenocheloides nomurai Komai, 2013, was reported from the Kii District (= Arita Bay, Kushimoto, Wakayama Prefecture), Japan. However, Komai's species is not to be included in Anker's genus Ctenocheloides, because of differences at the generic level with the type species of that genus, Ctenocheloides attenboroughi Anker, 2010, and is thus reclassified herein under a new genus, Kiictenocheloides gen. nov. Both genera, Ctenocheloides Anker, 2010 and Kiictenocheloides gen. nov. are also different from Ctenocheles Kishinouye, 1926, the type genus of the family Ctenochelidae Manning & Felder, 1991, so that the two genera, Ctenocheloides Anker, 2010 and Kiictenocheloides gen. nov. are now included in the family Ctenocheloidae Sakai, 2011. © 2013 Koninklijke Brill NV, Leiden.

Curcumin is a yellow pigment found in the spice turmeric and a main functional constituent of the rhizomes of Curcuma longa. The multi-functionality of curcumin has recently attracted much attention in various fields, including food, medicinal, and clinical industries. Three major curcuminoids, curcumin, demethoxycurcumin, and bis-demethoxycurcumin, are distributed in not only Curcuma, but also the Zingiber species; however, distribution of other curcuminoids is very limited in nature. The radical scavenging ability of curcumin, which is the basis of medicinal functionality, is its most important property. Herein, the structures of several rare curcuminoids that have been identified during the past four decades are summarized. Mechanistic studies of the radical trapping stage of curcumin are also comprehensively reviewed, and the studies on antioxidant effects derived from this radical trapping ability of curcuminoids are discussed. Various chemical reactions of curcumin, such as photo-oxidation, enzymatic oxidation, etc. are also summarized. In particular, antioxidation of curcumin in lipid media is introduced as a reaction unique to curcumin. © 2013 Bentham Science Publishers.

In this second report based on material collected by Prof. N. Zarenkov during the cruise of the R/V "Orlik" to the Gulf of Tonkin, Vietnam, in 1960, and on the cruise of the R/V "Akademik Kovalěvsky" to the Red Sea, both in 1960 and 1966, 11 species of the families Callianassidae and Upogebiidae are examined. It was found that the material includes two species, Cheramus malaccaensis (Sakai, 2002) and Trypaea tonkinae (Grebenjuk, 1975) from the Callianassidae, and Neogebicula alaini (Sakai, 1982), Paragebicula orlik sp. nov., P. vietnamensis sp. nov., Gebicula irawadyensis Sakai, 2006, Mantisgebia tuerkayi sp. nov., Upogebia acutispina De Saint Laurent & Ngoc-Ho, 1979, U. monoceros De Man, 1905, U. plantae Sakai, 1982, and U. variana sp. nov., i.e., a total of 9 species of which four are new, from the family Upogebiidae. © 2011 BRILL.

An important factor in medical nutritional therapy for elderly patients with diabetes is optimization of energy intake and macronutrient composition, with consideration of the food source and quality of nutrient. In addition, malnutrition and vitamin deficiency should be carefully considered. A dietary pattern that includes a high intake of vegetables, legumes, seaweed, and fish and a low intake of refined grains, sweets, sugar-sweetened beverages, and alcohol is favorable for diabetic patients. Particular attention should be paid to the excessive intake of sweets and fruits. Furthermore, the type and degree of physical function, cognitive function, lifestyle, social factors, medication, and hospitalization vary among elderly individuals. Therefore, individualized medical nutritional therapy that takes into account all these factors is essential.

The collections of the infraorders Thalassinidea Latreille, 1831 and Callianassidea Dana, 1852 logded in three German Museums, viz., Zoologische Staatssammlung, Munich (ZSM), Zoologisches Museum der Universität Hamburg, Hamburg (ZMH), and Museum für Naturkunde, Berlin (ZMB) were examined. The results of the present study indicate that the material of these collections comprises 10 families, 31 genera, including one new genus, and 73 species, three of which are new to science. © Koninklijke Brill NV, Leiden, 2014.

The present Axioidea-material was collected by the R/V "Hakuhou- maru", University of Tokyo, in 2005 and the R/V "Nagasaki-maru", University of Nagasaki, during biological surveys in the East China Sea in 2004-2005. The material collected during these cruises comprises three families, four genera including one new genus, and four species including three new species. These taxa are: Axiidae Huxley, 1879 with Acanthaxius Sakai & De Saint Laurent, 1989, A. gotoensis sp. nov., and Batyaxius gen. nov., B. sugurui sp. nov.; Calocarididae Ortmann, 1891 with Ambiaxius Sakai & De Saint Laurent, 1989, A. alcocki (McArdle, 1900); and Eiconaxiidae Sakai & Ohta, 2005 with Eiconaxius Bate, 1888, E. kumejimaensis sp. nov. © 2014 by Koninklijke Brill NV, Leiden.

Within the new classification of the superfamily Callianassoidea (cf. Sakai, 2010), six genera, including two new genera, with 13 species, including 7 new species and a previously reported form named herein as a new species, all based on material from the Gulf of Tonkin and the Red Sea, are examined in the present paper. In the Callianassidae Dana, 1852, subfamily Callianassinae, the genus Cheramus Bate, 1888 sensu Sakai (2010) includes C. anoplourus (Sakai, 2002) and C. malaccaensis (Sakai, 2002); the genus Notiax Manning & Felder, 1991 sensu Sakai (2010) includes N. bicauda sp. nov.; and the genus Trypaea Dana, 1852 sensu Sakai (2010) includes T. andamaniensis sp. nov., T. kovalewski sp. nov., T. spinoculata Sakai, 2005b, T. spinorostra sp. nov., T. tonkinae (Grebenjuk, 1975), and T. vietnamensis sp. nov. In the subfamily Callichirinae Manning & Felder, 1991 the genus Callichiropsis gen. nov., is established based on the type species Callichiropsis spiridonovi sp. nov. In the second family, Gourretiidae Sakai, 1999, the genus Paragourretia Sakai, 2004 includes P. zarenkovi sp. nov. and Paragourretia sp., and in the third family here examined, Micheleidae Sakai, 1992, the genus Micheleopsis gen. nov. is established on the basis of the type species Micheleopsis orlik sp. nov. © 2010 Koninklijke Brill NV, Leiden.
