In this review paper we consider the polynuclear growth (PNG) model in one spatial dimension and its relation to random matrix ensembles. For curved and flat growth the scaling functions of the surface fluctuations coincide with limit distribution functions coming from certain Gaussian ensembles of random matrices. This connection can be explained via point processes associated to the PNG model...

Access to basic healthcare in many parts of Papua New Guinea (PNG) remains a challenge partly because the majority of the population is thinly scattered across a geographically rugged country. The major health problems in PNG pertain to malaria, tuberculosis and diarrheal diseases while HIV has reached epidemic levels. The proliferation of the mobile phone technology in PNG has been unprecedent...

Commitment of political leadership The PNG government have been committed to improving maternal and child health. A number of reports over the past 5 years have highlighted the problems and proposed solutions including the Ministerial Taskforce on Maternal Health in PNG (2009); and the PNG Child Health Policy & Plan 2009-2020. These two reports particularly give a clear indication of the commit...

Antibiotic-resistant strains of Neisseria gonorrhoeae have the potential to undermine treatment and control of gonorrhoea, which remains a highly prevalent sexually transmitted infection (STI) in Papua New Guinea (PNG). The standard treatment regimen for gonorrhoea in PNG based on amoxycillin and clavulanic acid (amoxycillin-clavulanate) was introduced about 15 years ago and there is some conce...

Following completion of meiosis, DNA replication must be repressed until fertilization. In Drosophila, this replication block requires the products of the pan gu (png), plutonium (plu) and giant nuclei (gnu) genes. These genes also ensure that S phase oscillates with mitosis in the early division cycles of the embryo. We have identified the png gene and shown that it encodes a Ser/Thr protein k...

Firas A. Jassim Faculty of Administrative Sciences Management Information Systems Department Irbid National University Irbid, 2600, Jordan [email protected] Abstract Image compression is an important filed in image processing. The science welcomes any tinny contribution that may increase the compression ratio by whichever insignificant percentage. Therefore, the essential contribution in this...

Seventy-five % of the world's oral cancers arise in developing countries. In high incidence areas of Southeast Asia such as Papua New Guinea (PNG) the major region-specific risk exposure is betel quid chewing. While it has been shown that p53 gene mutations in the conserved midregion (exons 5-9) are a common feature of oral cancers in the developed world, there is no information on this type of...

(-)-Epigallocatechin-3-gallate (EGCG), the major bioactive constituent in green tea, has been reported to effectively inhibit the formation and development of tumors. To maximize the effectiveness of EGCG, we attached it to nanogold particles (EGCG-pNG) in various ratios to examine in vitro cytotoxicity and in vivo anti-cancer activity. EGCG-pNG showed improved anti-cancer efficacy in B16F10 mu...

Protein N-glycosylation (PNG) is crucial for protein folding and enzymatic activities, and has remarkable diversity among eukaryotic species. Little is known of how unique PNG mechanisms arose and evolved in eukaryotes. Here we demonstrate a picture of onset and evolution of PNG components in Golgi apparatus that shaped diversity of eukaryotic protein N-glycan structures, with an emphasis on ro...

The prevalence of typhoid in the Papua New Guinea (PNG) highlands region increased rapidly in the mid-1980s, and now remains endemic. In this study ribotyping has been used to examine the number and types of Salmonella enterica serovar Typhi strains present during the 1977-1996 period. The ribotyping banding pattern results were based on Cla I and Eco RV digests. The 57 PNG isolates were divide...
