Honey
A sweet viscous liquid food, produced in the honey sacs of various bees from nectar collected from flowers. The nectar is ripened into honey by inversion of its sucrose sugar into fructose and glucose. It is somewhat acidic and has mild antiseptic properties, being sometimes used in the treatment of burns and lacerations.
Protozoan Infections
Maple Syrup Urine Disease
An autosomal recessive inherited disorder with multiple forms of phenotypic expression, caused by a defect in the oxidative decarboxylation of branched-chain amino acids (AMINO ACIDS, BRANCHED-CHAIN). These metabolites accumulate in body fluids and render a "maple syrup" odor. The disease is divided into classic, intermediate, intermittent, and thiamine responsive subtypes. The classic form presents in the first week of life with ketoacidosis, hypoglycemia, emesis, neonatal seizures, and hypertonia. The intermediate and intermittent forms present in childhood or later with acute episodes of ataxia and vomiting. (From Adams et al., Principles of Neurology, 6th ed, p936)

The taxonomy of Armillaria in southern South America has received little attention since the work of Singer and others. In this study we examine the morphological traits and cultural features for taxa representing the lineages revealed based on molecular phylogeny, and we link them to previously described taxa based on morphology. Lineages I-IV were identified as Armillaria novae-zelandiae, A. montagnei, A. umbrinobrunnea comb. nov. and A. sparrei respectively. They could be differentiated morphologically based on dimension, features of the epicutis, annulus, stipe, hymenophoral trama and flavor and characteristics in culture. Furthermore there was no evidence of host preference for the species recognized. This is the first study integrating the phylogeny and morphology of Armillaria species from Patagonia, and it provides a foundation for future research on these fungi in South America.

(+info)Sequence-based identification of Japanese Armillaria species using the elongation factor-1 alpha gene. (6/12)
We analyzed the sequences of three DNA regions-the translation elongation factor-1 alpha (EF-1 alpha) gene and the internal transcribed spacer (ITS) and intergenic spacer (IGS) regions of ribosomal DNA-to compare their accuracy in identifying species of Japanese Armillaria. We studied 49 isolates of eight Armillaria species, A. mellea, A. ostoyae, A. nabsnona, A. cepistipes, A. gallica, A. sinapina, A. tabescens and the biological species Nagasawa E (Nag. E). Phylogenetic analyses of the ITS and IGS data helped in identifying A. mellea, A. ostoyae, A. nabsnona, A. tabescens and Nag. E but could not be used to identify A. gallica, A. cepistipes and A. sinapina. Nevertheless our analysis showed that the EF-1 alpha gene was clearly different in the eight examined species. Restriction fragment length polymorphisms (RFLP) of the IGS-1 region could be used to distinguish most species, but the RFLP profiles of some isolates of A. cepistipes and A. sinapina were the same even with four different restriction enzymes. In conclusion, among the techniques examined in this study, analyzing the EF-1 alpha sequence was found to be the most suitable method for identifying different species of Japanese Armillaria.
