Translocation of silver nanoparticles in the ex vivo human placenta perfusion model characterized by single particle ICP-MS

Author J. Vidmar, K. Loeschner, M. Correia, E. Larsen, P. Manser, A. Wichser, et al. Source Royal Society of Chemistry- Nanoscale, 2018, 10, 11980-11991 Summary Abstract: With the extensive use of silver nanoparticles (AgNPs) in various consumer products their potential toxicity is of great concern especially for highly sensitive population groups such as pregnant women and even the developing fetus. To understand if AgNPs are taken up and cross the human placenta, we studied their translocation and accumulation in the […]

Size distribution of ultrafine particles generated from residential fixed-bed coal combustion in a typical brazier

Author DM Masekameni, D. Brouwer, T. Makonese, IT Rampedi and M. Gulumian Source DOI: 10.4209/aaqr.2018.03.0105 Summary Abstract: Ultrafine particles of small mean diameter released from domestic coal combustion is an important parameter to consider as it affects air quality and human health. It is suggested that poor combustion conditions release particles of different sizes enriched with health-damaging chemicals such as polycyclic aromatic hydrocarbons. Furthermore, both smouldering and high efficient combustion conditions release particles, which are often carcinogenic. Information on fixed-bed […]

Is there a relationship between lead exposure and aggressive behavior in shooters?

Author N. Naicker, P. de Jager, S. Naidoo and A. Mathee Source Int. J. Environ. Res. Public Health 2018, 15, 1427; doi:10.3390ijerph15071427 Summary Abstract: Lead exposure has been associated with psycho-neurological disorders. Elevated blood lead levels have been found in shooters. This study assesses the association between the blood lead levels of shooters and their levels of aggression. An analytical cross-sectional study was conducted in Gauteng, South Africa. Participants were recruited from four randomly selected shooting ranges with three randomly […]

Efficacy assessment of ultraviolet germicidal irradiation (UVGI) devices for inactivating airborne Mycobacterium tuberculosis

Author T. Singh, Z. Ngcobo, O. Kgasha, W. Leuschner, O. Matuka, T. van Reenen, P. de Jager Source Occupational Health Southern Africa. Vol 24 No 4; July/ August 2018 Summary Introduction: Airborne transmission of Mycobacterium tuberculosis (TB) and other infectious agents within indoor environments has been a recognized hazard for decades. The increasing incidence of airborne diseases and drug resistance has renewed interest in ultraviolet germicidal irradiation (UVGI) to reduce transmission. The aim of this study was to determine the […]

Drivers of international variation in prevalence of disabling low back pain: Findings from the cultural and psychosocial influences on disability study

Author D. Coggon, G. Ntani, KT Palmer, VE Felli, F. Harari, LA Quintana, et al. Source European Journal of Pain. 2018. DOI: 10.1002/ejp.1255 Summary Background: Wide international variation in the prevalence of disabling low back pain (LBP) among working populations is not explained by known risk factors. It would be useful to know whether the drivers of this variation are specific to the spine or factors that predispose to musculoskeletal pain more generally. Methods: Baseline information about musculoskeletal pain and […]
