The genus Manota is found to consist of 37 species in the South Pacific region. The following 13 species are described as new: M. acris sp. n. (Papua New Guinea (PNG)), M. alulata sp. n. (PNG), M. apentachaeta sp. n. (PNG), M. clivicola sp. n. (PNG), M. cordata sp. n. (PNG), M. feminea sp. n. (PNG), M. kaindiensis sp. n. (PNG), M. lunata sp. n. (PNG), M. nimia sp. n. (Solomon Is.), M. pentachae...

Eighteen Schiff Bases of 3-amino-2-methylquinazolin-4(3H)-ones were synthesised and screened for anti-inflammatory and diuretic activity. Anti-inflammatory activity was identified in PNG-1, PNG-13, PNG-14, PNG-15 and PNG-17.

High resolution mitochondrial DNA (mtDNA) restriction maps, consisting of an average of 370 sites per mtDNA map, were constructed for 119 people from 25 localities in Papua New Guinea (PNG). Comparison of these PNG restriction maps to published maps from Australian, Caucasian, Asian and African mtDNAs reveals that PNG has the lowest amount of mtDNA variation, and that PNG mtDNA lineages origina...

The oocyte-to-embryo transition involves extensive changes in mRNA translation, regulated in Drosophila by the PNG kinase complex whose activity we show here to be under precise developmental control. Despite presence of the catalytic PNG subunit and the PLU and GNU activating subunits in the mature oocyte, GNU is phosphorylated at Cyclin B/CDK1sites and unable to bind PNG and PLU. In vitro pho...

Three new ganglioside molecular species, termed PNG-1, PNG-2A, and PNG-2B were isolated from pyloric caeca of the starfish Protoreaster nodosus. Their structures were elucidated using a combination of spectroscopic and chemical methods, and characterized as 1-O-[8-O-methyl-N-acetyl-α-neuraminosyl-(2→3)-β-galactopyranosyl]-ceramide for PNG-1, 1-O-[β-galactofuranosyl-(1&#8594...

The taxonomy of small, unicolor brown to black Papuasian species of the genus Onthophagus Latreille, 1802 is discussed. Two multi-species groups are defined in the nominotypical subgenus Onthophagus, one with broad and one with narrow dorsal eye foramina (O. acerus and O. kokodentatus groups, respectively). Twelve species are listed, keyed, and diagnosed. Ten of these are new species from Papua...

In Drosophila, fertilization is required for the embryo to undergo the first 13 rapid cell cycles, which consist of alternating DNA replication and mitosis without gap phases. In contrast, eggs from females mutant in the pan gu (png) locus no longer require fertilization to initiate DNA replication, and both fertilized embryos and unfertilized eggs from png mutant mothers have giant polyploid n...

Early embryonic cell cycles in Drosophila consist of rapidly alternating S and M phases. Three genes, pan gu (png), plutonium (plu), and giant nuclei (gnu) coordinate these early S-M cycles by ensuring adequate Cyclin B protein levels. Mutations in any of these genes result in unregulated DNA replication and a lack of mitosis ("giant nuclei" phenotype). png encodes a serine/threonine protein ki...
