This study presents the molecular phylogenetic relationships among Lytorhynchus diadema (Duméril, Bibron & Duméril, 1854) populations in Saudi Arabia relative to from Africa and Asia. analysis was based on mitochondrial 16S 12S rRNA partial gene fragments using Neighbor-joining, Maximum Parsimony, Bayesian methods. The results strongly support monophyly of two concatenated genes separat...

A large-type sexannulate leech species, Orobdella ibukifukuyamai sp. nov. , from Kii-Oshima Island, Japan, is described based on morphologic and molecular data. Phylogenetic analyses using nuclear 18S rRNA, 28S histone H3, mitochondrial cytochrome c oxidase subunit I, tRNA Cys Met 12S Val 16S Leu NADH dehydrogenase 1 markers showed that O. formed a clade with the okanoi Nakano, 2016 yamaneae oc...

Vitamin B(12), reduced by titanium (III) citrate to vitamin B(12s), catalyzes the reductive dechlorination of chlorophenols. Reductive dechlorination of pentachlorophenol and of all tetrachlorophenol and trichlorophenol isomers was observed. Reaction of various chlorophenols with vitamin B(12) favored reductive dechlorination at positions adjacent to another chlorinated carbon, but chlorines or...

DNA sequence comparisons are useful for characterizing proposed new parasite species or strains. Microfilariae with an atypical arrangement of nuclei behind the cephalic space have been recently described in human blood samples from the Amazon region of Peru. Three blood specimens containing atypical microfilariae were genetically characterized using three DNA markers (5S ribosomal DNA, 12S rib...

Three monophyletic branches are strongly supported in a phylogenetic analysis of the Teloschistaceae based on combined data sets of internal transcribed spacer and large subunit nrDNA and 12S small subunit mtDNA sequences. These are described as new monotypic genera: Jasonhuria S. Y. Kondr., L. Lőkös et S. -O. Oh, Loekoesia S. Y. Kondr., S. -O. Oh et J. -S. Hur and Olegblumia S. Y. Kondr., L. L...

Wittkower, M.D. With an Introduction by John Rickman, M.D. National Association for Prevention of Tuberculosis, Tavistock House North, W.C.I. 12s. 6d. Dr. Eric Wittkower is known throughout the world as an expert research psychiatrist in the psychosomatic field. The puzzling variety of reactions of the human body to the invasion of tuberculosis is made more clear by this study. The findings of ...

Tryptic activation of prototoxin of Clostridium botulinum type E increased the lethal toxicity by 250-fold, but no compatible increase in the antitoxin-combining power resulted. The formol toxoid derived from prototoxin and that from trypsin-activated 12S toxin were the same in the antigenic specificity, but prototoxin toxoid stimulated formation of a larger amount of antitoxin in guinea pigs a...

The water-soluble part of the methanolic extract from the aerial parts of Scrophularia crypthophila, through chromatographic methods, yielded three new resin glycosides, crypthophilic acids A - C (1-3). Compounds 1-3 are tetraglycosides of (+)-3S,12S-dihydroxypalmitic acid. The structures of these and 10 known compounds were elucidated by spectroscopic and chemical means. All natural resin glyc...

Subtraction games are \simple" variants of the famous Nim game Bou 01]. In this note we will show that in some subtraction games the sequences of Win/Loss states have superlinear period lengths. Our most prominent observation is: For all s with 1 s 26 the (s,4s,12s+1,16s+1)-game has the cubic period length 56s 3 + 52s 2 + 9s + 1. Possibly, the (s,8s,30s+1,37s+1,38s+1)-games with s 2 N have su-p...

precise information about the interaction between retinylidene chromophore and protein moiety of (1) in the intermediates (1). In the previous paper (2), it had been chemically confirmed from the CD data (Table 1) of the rhodopsin analog (2) involving the 10-20 bonded structure that the ƒ¿-CD-band of (1) is due to the twisted 12s-trans-conformation in the chromophore. This is strong evidence su...
