The spadix of skunk cabbage, Symplocarpus foetidus, is thermogenic and maintains an internal temperature of around 20 degrees C even when the ambient air temperature drops below freezing. This homeothermic heat production is observed only during the stigma stage, and thereafter ceases at the male stage when pollen is shed. ...

Agar diffusion testing was used with four different media to evaluate the antibacterial activity of six products (one conventional glass-ionomer cement (GIC), two light-activated glass-ionomers, two polyacid-modified resin composites and one resin composite) on Streptoccoccus mutans. Their respective antibacterial activities were also compared during and after setting. The relationship between ...

Automatic comparison of compositionally biased genomes, such as that of the malarial causative agent Plasmodium falciparum (82% adenosine + thymidine), with genomes of average composition, is currently limited. Indeed, popular tools such as BLAST require that amino acid distributions be similar in aligned sequences. However, the P. falciparum genome is ...

Analysis of the fatty acid (FA) composition of blubber is a valuable tool in interpreting the diet of marine mammals. This technique is based on the principle that particular FA present in prey can be incorporated largely untransformed into predator adipose tissue stores, thereby providing biochemical signatures with which to ...

Little is known about the molecular composition of the biodegradable fraction of dissolved organic matter (BDOM) in stream ecosystems. We combined plug-flow biofilm reactors, tetramethylammonium hydroxide (TMAH) thermochemolysis GC-MS, and 13C-labeled TMAH thermochemolysis GC-MS to study the molecular composition of BDOM from two stream ecosystems. TMAH products derived from fatty ...

INTRODUCTION: Fibrin glues are currently used by surgeons and can facilitate the handling of biomaterials. Combining fibrin glue with calcium phosphate bioceramics gives a mouldable composite that cements the granules into the implantation site. In addition to the mechanical aspect of the composite, it has been suggested that the mixture ...

Amino acid substitution matrices play a central role in protein alignment methods. Standard log-odds matrices, such as those of the PAM and BLOSUM series, are constructed from large sets of protein alignments having implicit background amino acid frequencies. However, these matrices frequently are used to compare proteins with markedly different ...

The recently described facultatively anaerobic Promicromonospora pachnodae is phylogenetically only moderately related to authentic members of Promicromonospora. P. pachnodae is closely related to Xylanibacterium ulmi and slightly less closely related to Xylanimonas cellulosilytica and Isoptericola variabilis (basonym Cellulosimicrobium variabile). Members of the different genera of Promicromonosporaceae have similar chemotaxonomic properties; ...

The amino acid compositions of 11 Gram-positive and 12 Gram-negative eubacteria were determined from their complete genomes. They were classified into two groups, 'S-type' represented by Staphylococcus aureus and 'E-type' represented by Escherichia coli, based on their patterns of amino acid compositions determined from the complete genome. These two groups ...
