Shedding Light On DNA Mechanisms
By manipulating individual atoms in DNA and forming unique molecules, a Georgia State University researcher hopes to open new avenues in research towards better understanding the mechanisms of DNA replication and transcription, and perhaps leading to new treatments for diseases.

Quantification Of Perfusion & Permeability In Prostate Using Dynamic Contrast-Enhanced MRI With Inversion-Prepared Dual-Contrast Sequence
UroToday.com - The dynamic contrast-enhanced dynamic susceptibility contrast magnetic resonance imaging (DCE-DSC-MRI) technique presented in the article(1) is based on a novel dual-contrast sequence. The sequence is a gradient echo sequence that uses a single inversion pulse and subsequent acquisition of two contrasts/echoes with different inversion and echo times. Inversion preparation increases the signal-to-noise ratio in comparison to other gradient echo sequences. The blood volume in the prostate is relatively small, i.e., approximately one percent, while the interstitial contrast-agent-enhancing volume is approximately 20 percent. Therefore, conventional imaging sequences fail to separate the low contrast agent signal originating from the blood from that originating from interstitial tissue. The first contrast/echo is acquired with a short echo time and is T1-weighted, allowing quantification of the total signal contribution while failing to separate the blood signal from the interstitial contrast agent signal.

Swine Flu Pandemic Weekly Report, Wales

from your hands to face or to other people. - Cleaning hard surfaces (e.g. door handles) frequently using a normal cleaning product. - Helping your children follow this advice. Control measures -- Agreements have been signed between the UK Government and vaccine manufacturers to secure enough vaccine for the whole population. The first batches are expected in August with around 60 million doses by the end of the year - enough for 30 million people to be vaccinated - with more following after that. The European Medicines Agency has strict processes in place for licensing pandemic vaccines. In preparing for a pandemic, appropriate trials to assess the safety and the immune responses have been carried out on vaccines very similar to the swine flu vaccine. -- The Welsh Assembly Government"s Health Emergency Preparedness Unit has issued guidance to Local Health Boards on anti-viral distribution. The unit is co-ordinating work on identifying appropriate collection points and the necessary arrangements to support this process. Features of the outbreak -- Based on assessment of all available information and following several expert consultations, the World Health Organization (WHO) declared the level of influenza pandemic alert at phase six on 11 June 2009. -- Phase six indicates there is human-to-human spread of the virus in at least two countries in one World Health Organization region, with community level outbreaks in at least one other country in a different WHO region. -- On 2 July the four UK nations agreed to move to the treatment phase in their response to the pandemic - treating people most at risk. Contact tracing and the use of antivirals preventively have been ended. GPs will now provide clinical diagnosis of swine flu cases rather than awaiting laboratory test results. Further information -- Further health information for the public on swine flu is available bilingually from http://www.nhsdirect.wales.nhs.uk -- Further public health information on swine flu and Pandemic Flu is available bilingually from http://www.nphs.wales.nhs.uk -- Further information from the Welsh Assembly Government response is available bilingually at http://www.wales.gov.uk Welsh Assembly Government
