Radiograph based SDD and SRD calculations KU Leuven

Gabriel Probst, Evelina Ametova, Jean-Pierre Kruth, Wim Dewulf
For high measurement accuracy with X-ray computed tomography (CT), that requires no scale calibration afterwards, due to incorrect assessment of voxel size during a CT scan, object magnification needs to be precisely calculated in order to minimize scale error of the reconstructed volume. Magnification, which is given by the z-axis of the machine’s coordinate system, is defined by the ratio between the source-detector (SDD) and source-rotation ...

IncI1 ST3 and IncI1 ST7 plasmids from CTX-M-1-producing Escherichia coli obtained from patients with bloodstream infections are closely related to plasmids from E. coli of animal origin Vrije Universiteit Brussel

Adam Valcek, Louise Roer, Søren Overballe-Petersen, Frank Hansen, Valeria Bortolaia, Pimlapas Leekitcharoenphon, Helle B. Korsgaard, Anne Mette Seyfarth, Rene S. Hendriksen, Henrik Hasman, et al.

OBJECTIVES: Fully sequenced IncI1 plasmids obtained from CTX-M-1-producing Escherichia coli of human and animal origin were compared. METHODS: Twelve E. coli isolates sharing identical ESBL genes and plasmid multilocus STs sequenced on Illumina and MinION platforms were obtained from the Danish antimicrobial resistance surveillance programme, DANMAP. After de novo assembly, the sequences of plasmids harbouring blaCTX-M-1 were manually curated ...

STM, STS and bias-dependent imaging on organic monolayers at the solid-liquid interface KU Leuven

S Lei, Steven De Feyter
This chapter deals with various aspects of scanning tunneling spectroscopy (STS) and in particularit reviews STS investigations on organic films. Though this chapter addresses in particular thosesystems which have been probed under ambient conditions and at the solid-liquid interface, a significantpart deals with studies under UHV conditions. Some key principles of STS are highlighted and variousmolecular systems are reviewed, ranging from ...

STD services for women at truck stop in Tanzania: evaluation of acceptable approaches Institute of Tropical Medicine

K Nyamuryekung'e, U Laukamm-Josten, C Mbuya, C Hamelmann, A Outwater, R Steen, D Ocheng, A Msauka, G Dallabetta
AIDS continues to be the commonest cause of death in Tanzania among those aged between 15 and 45 years. Both ulcerative and non-ulcerative sexually transmitted diseases have been identified as major co-factors in HIV transmission. Certain groups including long distance truck drivers and their sexual partners have been reported as having a disporportionate effect on the transmission dynamics of STD including HIV, in a population. In 1993 African ...

Evidence of declining STD prevalence in a South African mining community following a core-group intervention Institute of Tropical Medicine

R Steen, T DeCoito, S Ralepeli, G Fehler, J Conley, L Bruckers, G Dallabetta, R Ballard
Objectives: To reduce the prevalence of curable sexually transmitted diseases (STDs) in a South African mining community through provision of STD treatment services, including periodic presumptive treatment and prevention education to a core group of high-risk women living in areas around the mines.

Methods: Women at high risk for STDs attended a mobile clinic monthly for examination and counseling, and were treated presumptively for ...

Indicators and the measurement of STD case management in developing countries Institute of Tropical Medicine

TJ Saidel, R Steen, NS Niang, F Behets, H Khattabi, L Manhart, A Brathwaite, I Hoffman, G Dallabetta
The paper reviews methodologies for measuring quality of sexually transmitted disease (STD) case management through facility based assessments. These include observations and interviews of providers, as promoted by the World Health Organization's Global Programme on AIDS, and some of the viable alternatives including patient exit interviews, mystery patients, record review and patient encounter forms with supervisory visits. The paper concludes ...
