Polyporous Metal-Coordination Frameworks
Organic Letters, 2012Starting from a chiral building block--α-cyclodextrin--and rubidium salts, the crystallization of a complex of chiral helices, which constitute a "green" porous coordination polymer, has been realized. Cyclodextrin molecules coordinated by rubidium ions form porous, infinitely long left-handed helical channels, interdigitated with each other.

Monoporous and Polyporous Acne
Archives of Dermatology, 1959A comedo, or blackhead, may be defined as a plug of sebaceous material found in a duct of a sebaceous gland. It is most commonly seen as the elementary lesion of acne vulgaris, but it may also be present in linear nevi, postradiation atrophy, hidradenitis suppurativa, and tar acne.1-3 A single comedo may have more than one opening on the skin.

Archives of Dermatology, 1960
Sebaceous and epithelial cysts are common complications of acne. Another type of cyst seen in acneform eruptions is a polyporous comedonal cyst (Fig. 1A). A polyporous comedo is a blackhead with multiple openings.1Ocassionally, the sinusoidal connecting channels of a polyporous comedo become dilated and form a cyst.

Antileukæmic Activity of Polyporic Acid
Nature, 1959IN the course of screening indigenous plant products for experimental anti-cancer activity, a preparation of the lichen Sticta coronata was found to prolong significantly the life-span of mice previously inoculated with an acute lymphocytic leukaemia. Polyporic acid (2,5-dihydroxy 3,6 diphenyl 1,4 benzoquinone) isolated from Sticta coronata was shown ...

Studies in the taxonomy of the Polypores II
Folia Geobotanica et Phytotaxonomica, 1966The new genus Strangulidium Pouz. is proposed for two species: S. sericeo-molle and S. rennyi. The genus Chaetoporus is divided into two sections: Chaetoporus and Cyanochaetoporus. New species Chaetoporus separabilimus is described. New combinations are proposed: Hapalopilus salmonicolor and Chaetoporus collabens.

Synopsis of Louisiana Polypores
American Midland Naturalist, 1959The objective of this paper is to make a survey of the polypores that have been reported from Louisiana to the present time. One of the first lists of Louisiana fungi was published by Featherman (1871, 1872) reporting some fifteen species. The most comprehensive list of Louisiana polypores published in the eighteen hundreds was that of the Rev. A.

Mycologia, 1941
A stipitate polypore was observed and studied by Mr. J. B. Flett in Bremerton, Washington, from 1931 to 1939. It was first noticed because of its stature (up to 17 cm. tall), its exceedingly brittle and hygrophanous tissues and the bluish-green 1 coloration of the pilei.
