Total Dietary Fiber and Mineral Absorption

Gordon, Dennis-T. The Korean Nutrition Society 1992 Journal of Nutrition and Health Vol.34 No.3

The consumption of foods rich in TDF should not be associated with impaired mineral absorp-tion and long-term mineral status. In surveys of populations consuming high amounts of TDF e.g Third World populations and vegetarinas gross deficiencies in mineral nutrition have not been noted. If mineral status is low among these groups it is most likely caused by the inadequacy or imbalance of the diet and not by the TDF. The key word is interaction which should be inte-rpreted in dietary imbalances that produce nut-rient deficiencies. There are no strong data to support the concept that TDF inhibits mineral absorption through a binding chelation mechanism. Limited data sug-gest that positively charged groups on polymers such as chitosan and cholestyramine will decrease iron absorption in humans and animals. Because TDF does not contain positively charged groups future research should be directed at the possible role of protein consumed along with TDF and the combination of effects on mineral nutrition Phytic acid is acknowledged as a potent chela-tor of zinc. However its association with zinc and its propensity to lower Zn bioavaiability may enhance the absorption of other elements notably copper and iron. The importance of interactions among nutrients including TDF will gain addi-tional attention in the scientific community. Soluble and insoluble dietary fiber function di-fferently in the intestine. Insoluble fibers accele-rate movement through the intestine. Soluble die-tary fibers appear to regulated blood concentra-tions of glucose and cholesterol albeit by some unknown mechanism. In creased viscosity produ-ced by the SDF in the intestine may provide an explanation of how this class of polymers affects plasma glucose cholesterol and other nutrients. Employing a double-perfusion technique in the rat we demonstrated that viscosity produced by SDF will delay transfer of zinc into the circulatory system. This delayed absorption should not be interpreted as decreased utilization. A great deal of additional research is required to prove the importance of luminaly viscosity produced by SDF on slowing nutrient absorption or regulating bllod nutrient homeostasis. Increased intake of TDF in the total human diet appears desirable. A dietary intake of 35g/day should not be considered to have a negative effect on mineral absorption. It is important to educate people that an intake of more than 35g TDF/day may cause an imbalance in the diet that can adve-rsely affect mineral utilization. Acknowledgments.

Sixteen new generic records of Korean Bryozoa from southern coastal waters and Jeju Island, East China Sea: evidence of tropical affinities

YANG, HO JIN,SEO, JI EUN,GORDON, DENNIS P. Magnolia Press 2018 Zootaxa Vol.4422 No.4

<P>The first records of 16 genera of cheilostome Bryozoa not previously reported for Korea are given here. All are from southern coastal waters, especially Jeju Island, which appears to be Korea’s marine-biodiversity ‘hotspot’. Jodoella koreensis n. gen. et sp. (Robertsonidridae) is new to science. Seven additional new species are described for the genera Copidozoum, Reptadeonella, Schizosmittina, Saevitella, Torquatella, Stephanollona and Plesiocleidochasma. The other genera new to the Korean fauna are Dibunostoma, Corbulella, Onychocella, Stephanotheca, Bryopesanser, Calloporina, Hippaliosina and Pleuromucrum. The Japanese Pleistocene species Calloporina hayamiae Arakawa is newly reported alive from Jeju Island. Four of the species were previously known only from the tropical Indo-West Pacific, three others are found in semitropical/warm-temperate water, and the other known genera have warm-water species, supporting data from other taxa that Korean’s southern waters, especially in the vicinity of Jeju Island, are profoundly influenced by the warm Kuroshio Current and global warming trends. Currently, at least 112 species of Bryozoa are known from Jeju Island, 101 of them Cheilostomata, representing c. 70% of all Korean cheilostome species. Four new combinations are introduced: Copidozoum canui (Sakakura) n. comb., Schizo pedicellata (Soule, Soule & Chaney) n. comb., Torquatella ensenada (Tilbrook) n. comb. and Torquatella longiuscula (Harmer) n. comb. Torquatellidae is subsumed in Celleporidae and Predanophora in Torquatella. </P>

Systematics of some calloporid and lacernid Cheilostomata (Bryozoa) from coastal South Korean waters, with the description of new taxa

MIN, BUM SIK,SEO, JI EUN,GRISCHENKO, ANDREI V.,LEE, SANG-KYU,GORDON, DENNIS P. Magnolia Press 2017 Zootaxa Vol.4226 No.4

<P>Six species in two families of Cheilostomata-Calloporidae and Lacernidae-are described from the southern coasts of the Korean Peninsula, resulting in a new distributional record and four new species to the Korean fauna. Further, Woosukia n. gen. is described, based on an existing species. Two species names (Crassimarginatella crassimarginata and Arthropoma cecilii) are deleted from the Korean faunal list owing to previous misidentification, with the net result that the Korean cheilostome fauna is increased to 125 species. The new additions to the fauna are: Crassimarginatella kumatae (Okada), Retevirgula asiana n. sp., Woosukia subhexagona (Ortmann), Arthropoma magniporosum n. sp., Arthropoma minus n. sp., and Phonicosia crena n. sp. The biogeographic relationships of some western Pacific taxa are discussed. </P>

Intertidal Bryozoa from Korea-new additions to the fauna and a new genus of Bitectiporidae (Cheilostomata) from Baengnyeong Island, Yellow Sea

MIN, BUM SIK,SEO, JI EUN,GRISCHENKO, ANDREI V.,GORDON, DENNIS P. Magnolia Press 2017 Zootaxa Vol.4226 No.4

<P>Eight species are added to the intertidal bryozoan fauna of South Korea, all collected from the extreme northwestern part of the country at Baengnyeong Island. Five of the species (Hippothoa imperforata, Celleporella hyalina, Celleporella nodasakae, Porella donoghueorum and Suhius rubescentis) are new records. Cauloramphus dicki n. sp., Cauloramphus spencerjonesae n. sp., and Exochella cryptodontia n. sp. are new to science; Suhius n. gen. is a newly recognized genus in Bitectiporidae. The close morphological similarity of umbonuloid-shielded P. donoghueorum to Australasian and Antarctic species of lepralioid-shielded species of Aimulosia is discussed in relation to ascophoran phylogeny. The described cheilostome fauna from South Korea is herein increased to 121 species. </P>

Cribrilinidae (Bryozoa: Cheilostomata) of Korea

YANG, HO JIN,SEO, JI EUN,MIN, BUM SIK,GRISCHENKO, ANDREI V.,GORDON, DENNIS P. Magnolia Press 2018 Zootaxa Vol.4377 No.2

<P>The cribrilinid Bryozoa of Korea are described for the first time. Eight species are recognized, distributed in five genera: Cribrilina, Reginella, Jullienula, Figularia and Puellina. Juxtacribrilina n. subgen. is recognized as comprising a group of species within Cribrilina characterized, inter alia, by having adventitious avicularia, reduced and/or vestigial ooecia, a pair of proportionately long protective latero-oral costae that cross the front of the ooecium and fuse in the midline, and a cribrimorph ancestrula. Cribrilina (Juxtacribrilina) flavomaris n. sp., Jullienula erinae n. sp. and Puellina paracaesia n. sp. are so far known only from the west and southwest coasts of the Korean Peninsula. The following six new combinations are recognized: Cribrilina (Juxtacribrilina) annulata (Fabricius, 1780) n. comb., Cribrilina (Juxtacribrilina) corbicula O’Donoghue & O’Donoghue, 1923 n. comb., Cribrilina (Juxtacribrilina) mutabilis Ito, Onishi & Dick, 2015 n. comb., Reginella multipora (Sakakura, 1935) n. comb., Reginella biporosa (Okada, 1923) n. comb. and Jullienula ortmanni (Silén, 1941) n. comb. </P>
