Diseases are a potential threat to global food security but plants have evolved an extensive array of methodologies to cope with the invading pathogens. Non-host resistance and quantitative re- sistance are broad spectrum forms of resistance, and all kinds of resistances are controlled by extremely diverse genes called ＂R- genes＂. R-genes follow different mechanisms to defend plants and PAMP-induced defenses in susceptible host plants are referred to as basal resistance. Genetic and phenotypic diversity are vital in maize （Zea mays L.）; as such, genome wide association study （GWAS） along with certain other methodologies can explore the maximum means of genetic diversity. Exploring the complete genetic archi- tecture to manipulate maize genetically reduces the losses from hazardous diseases. Genomic studies can reveal the interaction be- tween different genes and their pathways. By confirming the specific role of these genes and protein-protein interaction （proteomics） via advanced molecular and bioinformatics tools, we can shed a light on the most complicated and abstruse phenomena of resistance.

Amiodarone is one of the widely used antiarrhythmic drugs related to class III, used in the treatment of SVT (supraventricular) and ventricular arrhythmias. However, improper use of this drug such as pushing high concentration with rapid injection can increase the rate of adverse effects. The most common adverse effects associated with intravenous amiodarone are hypotension (16%), heart block or bradycardia (4.9%), and peripheral phlebitis (8-55%), this can be treated by diluting the drug and slowing the rate of infusion or discontinuing the drug. In addition, hypotension can be refractory and lead to a fatal outcome and death. Because phlebitis may occur, the drug should be given through a central line when possible. Some literatures refer to the administration of intravenous amiodarone in the treatment of arrhythmias such as in SVT, as "given over 10 minute" without focusing on the dilution and rate of infusion, therefore many residents give it with rapid direct intravenous injection without dilution and even during less than 10 minutes. From currently daily practice we are reporting two cases of amiodarone improper administration, first case "amiodarone-associated refractory hypotension" and second case "amiodarone-associated death".

BACKGROUND: Cirrhotic Cardiomyopathy is a relatively ill-characterized condition, which is often under-diagnosed due to absence of defined diagnostic criteria. ECG showing corrected QT Interval prolongation is the most suitable available option for diagnosis of this condition. OBJECTIVE: To determine the frequency of corrected QT interval prolongation in patients with liver cirrhosis. METHODOLOGY: Patients (n = 166) with confirmed cirrhosis, 30 years or older, presented in the outpatient and emergency department of medicine at Capital Hospital Islamabad between 1 October 2011 and 30 September 2012, were enrolled in this cross-sectional study after taking consent. ECG was done using calibrated ECG machine, and the QT Interval was measured. Corrected QT was calculated using Bazett’s formula and a QTc of more than 0.44 seconds was considered as being prolonged. RESULTS: The mean age of the patients was 57.05 ± 12.03 years. The corrected QT Interval varied from 337 ms to 560 ms. The mean QTc Interval was 429.92 ms ± 45.11. QTc was prolonged in 41 out of 166 patients (24.7%). Frequency of QTc prolongation was 4.5% in Child Pugh Grade A, 23.2% in Child Pugh Grade B, and 32.0% in Child Pugh Grade C. Association of Child Pugh Scoring with QTc prolongation was determined and found to be statistically significant (P < 0.05). CONCLUSION: QTc interval was prolonged in 24.7% of cirrhotic patients in our study. There was a significant increase in frequency with worsening of Child Pugh Grade, thereby indicating an association between QTc prolongation and the severity of cirrhosis.
