Utility Of Mri In Assessment Of Pituitary Iron Overload, Abdul Mueed Zafar, Lubna Zuberi, Ameer Hamza Khan, Humera Ahsan Sep 2007

Utility Of Mri In Assessment Of Pituitary Iron Overload, Abdul Mueed Zafar, Lubna Zuberi, Ameer Hamza Khan, Humera Ahsan

Medical College Documents

Beta thalassemia is highly prevalent in Pakistan with a carrier rate of 5-8%. The main complication of beta thalassemia major is iron overload, especially in reticuloendothelial system, heart, joints and endocrine glands. Pituitary siderosis leads to hypogonadotropic hypogonadism and growth hormone deficiency. Measures of plasma ferritin levels and hepatic iron level are used for assessing body iron overload but these are limited for various reasons particularly in case of pituitary siderosis. Magnetic Resonance Imaging (MRI) is a reliable, non invasive and easily available utility for assessing tissue siderosis. We assessed a 20 year old female beta thalassemic diagnosed with hypogonadotropic …

The Wto Trade Effect, Pao Li Chang, Myoung-Jae Lee Sep 2007

The Wto Trade Effect, Pao Li Chang, Myoung-Jae Lee

Research Collection School Of Economics

Rose (2004) showed that the WTO or its predecessor, the GATT, did not promote trade, based on conventional econometric analysis of gravity-type equations of trade. We argue that conclusions regarding the GATT/WTO trade effect based on gravity-type equations are arbitrary and subject to parametric misspecifications. We propose using nonparametric matching methods to estimate the 'treatment effect' of GATT/WTO membership, and permutation-based inferential procedures for assessing statistical significance of the estimated effects. A sensitivity analysis following Rosenbaum (2002) is then used to evaluate the sensitivity of our estimation results to potential selection biases. Contrary to Rose (2004), we find the effect …

Role Of Stellate Ganglion Block In Post Cabg Sympathetically Mediated Chest Pain, Mueen Ullah Khan, Imtiaz Ahmed

Department of Anaesthesia

Acute chest pain is a common presentation in emergency. After clinical assessment undiagnosed chest pain can become a difficult problem. Sympathetically mediated chest pain is a rare presentation, as it is similar to that of secondary hyperalgesia in the intact skin surrounding an injury site. We are reporting a case of a 62 years old man who presented with atypical chest pain four months after coronary artery bypass grafting (CABG). On investigation no new change was noticed than previous evaluation. On chronic pain assessment he was having hyperalgesia to light touch in addition to the spontaneous chest pain. He was …

Fucosidosis And Anesthesia, Alireza E. Soltani, Reza S. Moharari, Reza Ghaffari, Hamid Zahedi, Mojgan Hajmahmoodi

Saudi Medical Journal

Fucosidosis is a rare, autosomal recessive lysosomal storage disorder caused by a severe deficiency of a-L-fucosidase. Patients usually have some problems with glycoprotein storage in the brain and other organs, and some structural abnormalities that need special consideration in anesthesia. It has 2 types, the early onset or infantile, and the juvenile. Here we present an 8-year old girl with deformities in the maxillofacial region, with big tongue, small and retracted chin, saddle nose, and short neck that could not be extended, causing difficult intubation, and congenital cardiac problems requiring a special anesthetic strategy.

Differential Resource Allocation In Deer Mice Exposed To Sin Nombre Virus, Eric Wilson, Erin M. Lehmer, Christine A. Clay, Stephen St. Jeor, Denise M. Dearing Sep 2007

Differential Resource Allocation In Deer Mice Exposed To Sin Nombre Virus, Eric Wilson, Erin M. Lehmer, Christine A. Clay, Stephen St. Jeor, Denise M. Dearing

Faculty Publications

The resource allocation hypothesis predicts that reproductive activity suppresses immunocompetence; however, this has never been tested in an endemic disease system with free-ranging mammals. We tested the resource allocation hypothesis in wild deer mice (Peromyscus maniculatus) with natural exposure to Sin Nombre Virus (SNV). Immunocompetence was estimated from the extent of swelling elicited after deer mice were injected with phytohemagglutinin (PHA); swelling is positively correlated with immunocompetence. After livetrapping deer mice, we determined their reproductive state and SNV infection status. Males were more likely to be seropositive for SNV than females (37% vs. 25%) and exhibited 10% less swelling after …

An Aminoacyl-Trna Synthetase: Elongation Factor Complex For Substrate Channeling In Archaeal Translation, Corinne D. Hausmann, Mette Praetorius-Ibba, Michael Ibba Sep 2007

An Aminoacyl-Trna Synthetase: Elongation Factor Complex For Substrate Channeling In Archaeal Translation, Corinne D. Hausmann, Mette Praetorius-Ibba, Michael Ibba

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Translation requires the specific attachment of amino acids to tRNAs by aminoacyl-tRNA synthetases (aaRSs) and the subsequent delivery of aminoacyl-tRNAs to the ribosome by elongation factor 1 alpha (EF-1α). Interactions between EF-1α and various aaRSs have been described in eukaryotes, but the role of these complexes remains unclear. To investigate possible interactions between EF-1α and other cellular components, a yeast two-hybrid screen was performed for the archaeon Methanothermobacter thermautotrophicus. EF-1α was found to form a stable complex with leucyl-tRNA synthetase (LeuRS; KD = 0.7 μ M). Complex formation had little effect on EF-1α activity, but increased the kcat …

The Mighty Pen, The Almighty Dollar, And The Holy Hammer And Sickle: An Examination Of The Conflict Between Trade Liberalization And Domestic Cultural Policy With Special Regard To The Recent Dispute Between The Us And China On Restrictions On Certain Cultural Products, Shuchao Henry Gao Sep 2007

The Mighty Pen, The Almighty Dollar, And The Holy Hammer And Sickle: An Examination Of The Conflict Between Trade Liberalization And Domestic Cultural Policy With Special Regard To The Recent Dispute Between The Us And China On Restrictions On Certain Cultural Products, Shuchao Henry Gao

Research Collection Yong Pung How School Of Law

The relationship between trade and culture has long been a hot topic in the debate on the conflicts between free trade and non-trade values. The recent case brought by the United States against China in the WTO on the measures affecting trading rights and distribution services for certain publications and audiovisual entertainment products is regarded by many as the latest example of the conflict. This article argues, however, that this case is more about the conflict between economic liberalization and political control. Applying the legal rules under the WTO Agreements and public international law, this paper concludes that the United …
