To determine the prevalence of elevated blood lead concentrations in preschool children in central and southern Sydney. Children aged from 9 months to 5 years living in 32 randomly selected geographical areas in Central and southern Sydney. Venous blood lead concentrations were estimated by atomic absorption spectrometry. 953 children were identified and 726 had parental consent to participate. A blood sample for lead estimation was obtained from 718 children. The geometric mean blood level concentration was 0.34 mu mol/L (7.0 mu/dL). The proportion of children with elevated blood lead concentrations was: 16.1% (>0.48 mu mol/L [10mu/dL]), 3.9% (>0.72 mu mol/L[15mu/dL]) and 0.3% (>1.21mu mol/L [25 mu/dL], respectively. The blood lead levels for children living with a 10-km radius of the Sydney Central Business district were: 25% (>0.48 mu mol/L [10mu/dL]) and 7% (>0.72 mu mol/L [15mu/dL]), respectively. Corresponding findings for children living 10 km outside this radius were: 9% (>0.48 mu mol/L [10mu/dL]) and 1.5% (0.72 mu mol/L [15mu/dL]), respectively. The proportion of children with elevated blood lead concentrations in Central and Southern Sydney as a whole does not exceed current National Health and Medical Research Counci...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Bone Marrow Neoplasms

Bone Marrow Neoplasms are cancers that occur in the bone marrow. Discover the latest research on Bone Marrow Neoplasms here.

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

LRRK2 & Immunity During Infection

Mutations in the LRRK2 gene are a risk-factor for developing Parkinson’s disease. However, LRRK2 has been shown to function as a central regulator of vesicular trafficking, infection, immunity, and inflammation. Here is the latest research on the role of this kinase on immunity during infection.

Antiphospholipid Syndrome

Antiphospholipid syndrome or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by the presence of antibodies directed against phospholipids.

Meningococcal Myelitis

Meningococcal myelitis is characterized by inflammation and myelin damage to the meninges and spinal cord. Discover the latest research on meningococcal myelitis here.

Alzheimer's Disease: MS4A

Variants within membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease by recent genome-wide association studies. Here is the latest research.
