The number of infections with penicillinase-producing Neisseria gonorrhoeae (PPNG) strains in Singapore has risen from three in 1976 to 1792 in 1979. In the latter year they formed 19.2% of all infections with gonorrhoea, and 1280 of the strains isolated were from female prostitutes. The prevalence of PPNG infections is analysed according to the different sections of the community and racial gr...

Kurzfassung. Die stereovideografische Dokumentation intraoperativer Befunde ist mit der Digitalisierung der Bildverarbeitungsprozesse ein viel versprechender Ansatz zur Verbesserung der medizinischen Ausbildung. Wir verwenden ein mikroskopisches Kamerasystem mit 1280× 720 Pixel Auflösung, welches das Signal beider Kanäle über eine PC-Workstation mit einem RAID-0-Array bei 18 fps aufzeichnet. Di...

Lignite (ulminite reflectance Rr = 0.27%) from the Szczerców deposit (Central Poland) is dominated by huminite group macerals, containing a high proportion of attrinite and densinite. Densinite ulminite are more abundant in small aromatic units than attrinite, which may result their stronger gelification. The differences Raman spectral characteristics between pronounced Fusinite, comparison wit...

Over-expression of PDGF receptors (PDGFRs) has been previously implicated in high-risk medulloblastoma (MB) pathogenesis. However, the exact biological functions of PDGFRα and PDGFRβ signaling in MB biology remain poorly understood. Here, we report the subgroup specific expression of PDGFRα and PDGFRβ and their associated biological pathways in MB tumors. c-MYC, a downstream target of PDGFRβ bu...

the copper level in the serum of 1280 and liver of 200 goats raised in the mountain areas of khuzestanprovince, iran were determined. copper, molybdenum and iron content of soil and pastures as well as sulfurcontent of the pastures were seasonally estimated. mean serum copper levels of goats in behbahan,ramhormoz, eizeh and masjed-soleyman districts were 8.14 ± 0.21, 1.98 ± 0.12, 7.74 ± 0.11 an...
