Geneset-based cancer survival analysis: On the non-uniform distributiuon of p-values under the null hypothesis
Esteban Czwan, Benedikt Brors, David Kipling

Although null p-values are assumed to be uniformly distributed in gene expression experiments, the actual distribution often deviates from the assumed distribution. This can incorrectly associate the biology of a geneset with cancer prognosis in geneset-based survival studies. To assess the implications of this, a geneset-based method was developed. This method empirically approximates the distribution of null p-values and tests whether predefined sets of biologically-related genes are associate

Clinical Outcomes and Emerging Challenges after 5 years of ART in Khayelitsha, South Africa
Gilles Van Cutsem1, Katherine Hilderbrand1,2, David Coetzee2,3, Carol Cragg3, Eric Goemaere1 & Andrew Boulle2,3

One of the first primary care antiretroviral treatment programs in Africa shows good patient outcomes at 5 years. Saturation of services has led to increased losses to follow-up.

Panic attack and suicide risk: A multivariate logistic regression analysis of a national epidemiological survey
Curren Katz, Ramin Mojtabai, Leo Bierman, Kathleen Camacho, Janine Samuel, Gillian Jennings, Igor Galynker

To examine the relationship between panic attack and suicide risk, we analyzed data from a representative epidemiological survey of 43,093 adults (NESARC) using logistic regression controlling for socio-demographic and clinical variables. In depression, panic attacks are associated with increased odds of suicide attempt even after controlling for demographic and clinical variables. Furthermore, panic attacks can differentiate those who attempt suicide from those with ideation only.

SYBR® Green I as a biomarker for schizophrenia
Davood Zaeifi, Mehdi Rahmati, Vahab Piranfar

The purpose of this study were to examine if the mRNA of the peripheral dopamine receptor is changed in schizophrenia patients. 50 Naive patients were enrolled. After extracting RNA from white blood cells, cDNA is synthesized. After doing the quantitative Real-time PCR, expression of D3 receptors in healthy persons and patients were compared. Results of this examinations reveals that expression of D3 receptor is increased in compared with controls sample.

What reduces ambulatory sensitive hospitalisation?
Arindam Basu and David Brinson

This poster showcases our review of interventions that were found to be effective in reducing ambulatory sensitive hospitalisations (ASH). ASH refers to those conditions where hospitalisations an be avoided by measures taken by clinicians and other carers at outpatient departments or in the community.

Anti-inflammatory activity of Dalbergia sissoo Roxb. heart-wood
Ohm Devani, S. K. Lahiri, D. D. Santani, M. B. Shah

The heart-wood of Dalbergia sissoo Roxb. is reported to be used in traditional medicinal practices, of which anti-inflammatory is one. The present work evaluates the effect of the heart-wood extract on the carrageenan induced rat paw edema. The drug was found to be active at lowest of 3 doses tried. the drug can be said to posses anti-inflamatory activity but needs further evaluation of discover the pathway of the same.

Point-of-care testing for prostate cancer diagnosis
Y. Uludag; I.E. Tothill

This presentation describes the potential of using a new fully automated QCM biosensor and a commercial SPR biosensor for the detection of PSA, a biomarker for prostate cancer. Initially a new buffer was formulated to eliminate 98% of the non-specific human serum protein binding to the sensors. Obtained results indicate that both instruments can be used for the fast and easy detection of PSA (0.29-150 ng/ml) in serum.
