UNLABELLED Phosphomannose isomerase (pmi) gene isolated from Escherichia coli allows transgenic plants carrying it to convert mannose-6- phosphate (from mannose), a carbon source that could not be naturally utilized by plants into fructose-6-phosphate which can be utilized by plants as a carbon source. This conversion ability provides energy source to allow the transformed cells to survive on t...

Mitochondria are highly dynamic organelles that can change in number and morphology during cell cycle, development or in response to extracellular stimuli. These morphological dynamics are controlled by a tight balance between two antagonistic pathways that promote fusion and fission. Genetic approaches have identified a cohort of conserved proteins that form the core of mitochondrial remodelli...

OBJECTIVES Elevated asymmetric dimethylarginine (ADMA) is associated with an increased risk of coronary artery disease. A prognostic value of ADMA following coronary artery bypass grafting (CABG) is unknown. The aim of the current study was to assess the effect of CABG on ADMA and oxidative stress and determine their associations with postoperative complications. METHODS In 158 consecutive pa...

The microenvironment of postpartum mammary gland involution (PMI) has been linked to the increased risk of breast cancer and poor outcome of patients. Nevertheless the mechanism underlying regulates the microenvironment remains largely unknown. MUC1, which is abnormally overexpressed in most breast cancer, is physiologically expressed in PMI. Using MUC1 cytoplasm domain (MUC1-CD) transgenic mic...

Percutaneous coronary intervention (PCI) may be complicated by periprocedural myocardial infarction (PMI) as manifested by elevated cardiac biomarkers such as creatine kinase (CK)-MB or troponin T. The occurrence of PMI has been shown to be associated with worse short- and long-term clinical outcome. However, recent studies suggest that PMI defined by biomarker levels alone is a marker of ather...

Generation of widely spaced polarization modulation instability (PMI) sidebands in a wide collection photonic crystal fibers (PCF), including liquid-filled PCFs, is reported. The contribution chromatic dispersion and birefringence to the net linear phase mismatch PMI investigated all-normal PCFs with one (or two) zero wavelengths. Large frequency shift are demonstrated experimentally. Suitable ...

Abnormalities in cardiomyocyte Ca2+ handling contribute to impaired contractile function in heart failure (HF). Experiments on single ryanodine receptors (RyRs) incorporated into lipid bilayers have indicated that RyRs from failing hearts are more active than those from healthy hearts. Here, we analyzed spontaneous Ca2+ sparks (brief, localized increased in [Ca2+]i) to evaluate RyR cluster acti...

ALKindy Col Med J 2015:Vol. 11 No. 2 69 www.kmjub.com Abstract: Background: No previous Iraqi study was done on the estimation of post mortem interval (PMI) from the medico-legal point of view; depending on the biochemical changes of vitreous humor. Objectives: To find out the relationship between some biochemical changes in vitreous humor and post mortem interval. To find out a new formula for...

PCI [1] , which underscores the need to monitor patients post-PCI and to develop therapeutic strategies to combat PMI. The assessment of circulating biomarkers such as troponin I or T and creatine kinase-MB (CK-MB) following PCI has become an important clinical tool for the identification of patients at risk for the development of PMI [1, 3, 4] . For example, a rise in circulating CK-MB levels ...

This article discusses post-merger integration (PMI) and the trade-off between the economic benefits and costs that arise when organizations merge under a new organizational structure and reconfigure their businesses and resources. To reconfiguration scholars, PMI is a crucial tool for firms to reconfigure resources, product lines, and business units to adjust to internal and external environme...
