وہی ہوا کہ تماشا لگانا پڑ گیا ناں
بڑا تھا شوق تمھیں سیدھی رہ دکھانے کا
سمجھ میں آیا کہ ہم لوگ چیختے کیوں تھے
جو لوگ دوستی کو بزدلی سمجھتے تھے
ستارا وار ابھرنے لگا ہوں آنکھوں سے
یہ لوگ موت سے کم پر تو خوش نہیں ہوتے
تمھیں بھی دکھ کو صحافت بنانا پڑ گیا ناں
تمام شہر مخالف بنانا پڑ گیا ناں
تمھیں بھی خوف رجسٹر کرانا پڑ گیا ناں
اب امن کے لیے جرگہ بٹھانا پڑ گیا ناں
دیے کی لو کو بڑھانا گھٹانا پڑ گیا ناں
سو زندہ رہنے کو مر کر دکھانا پڑ گیا ناں
Background: Non-atherosclerotic processes are regarded as equally important contributors to a substantial number of coronary problems mainly myocardial infarction. This includes coronary spasm which has been considered as one of the coronary syndromes leading to myocardial infarction. These non-atherosclerotic events ensuing in major averse cardiac events (MACE) not only require various diagnostic and therapeutic strategies but also there is a need to delineate the underlying etiology for their effective treatment and management. Case Summary: We report a case of anterior wall myocardial infarction (AWMI) driven by a non-atherosclerotic event i.e. Coronary spasm. Concomitant marked ST-segment elevation recorded on ECG revealed a diffuse mid distal disease in our patient. We report here the initial presentation, coronary care & intervention and throughout the clinical course of our patient. Conclusion: Myocardial infarctionsinvolving non-atherosclerotic causes in young individuals as in our study should be reported by medical practitioners and given equal importance as they might indicate the underlying root cause of such events. Effective treatment of such future cases can be done by taking management strategies, diagnostic findings and prognostic data into consideration.
The seeds of one hundred maize inbred lines collected from various research organizations were planted in two sets, one under normal and the other under high temperature conditions in a plastic tunnel for the purpose of screening against heat at reproductive stage. Based on the actual and relative values for leaf temperature, cell membrane thermo-stability, stomatal conductance, transpiration rate, leaf firing, kernels per ear, 100-grain weight and grain yield per plant, one heat tolerant (ZL-11271) and one heat susceptible (R-2304-2) parents were selected and crossed to develop six basic generations comprised parents (P1, P2), hybrid (F1) and segregating generations (BC1, BC2, F2) in subsequent cropping seasons. All these generations were then evaluated under both normal (field) and heat-stressed (plastic tunnel) conditions using factorial randomized complete block design with three replications. The recorded data under both the conditions on various morphological and physiological plant traits were analyzed in nested block design for one way, two way and partitioned analysis of variances which revealed statistically significant differences (P≤0.01-0.05) for all the characters except anthesis-silking interval. Generation mean analysis of plant traits recorded under normal conditions revealed both additive and dominance genetic effects alongwith epistatic interactions for leaf temperature, cell membrane thermo-stability, stomatal conductance, leaf firing, plant height, ear leaf area, days to maturity, ear length, kernels per ear, 100-grain weight and grain yield per plant. For all these traits except stomatal conductance, dominance effects were more pronounced than additive estimates. Only additive genetic effects alongwith epistatic interactions were revealed for transpiration rate, days to tasseling and days to silking under normal conditions. Days to silking and days to maturity had dominance genetic effects with no epistatic interaction while traits like leaf temperature, cell membrane thermo-stability, stomatal conductance, transpiration rate, leaf firing, plant height, days to tasseling, ear leaf area, ear length, kernels per ear, 100-grain weight and grain yield per plant revealed both additive and dominance genetic effects alongwith epistatic interactions under heat-stressed conditions. Additive genetic effects were greater in magnitude for leaf temperature, cell membrane thermo-stability and stomatal conductance while estimates of dominance genetic effects were higher in case of transpiration rate, leaf firing, plant height, ear leaf area, ear length, kernels per ear, 100-grain weight and grain yield per plant under heat-stressed regime. Estimates of broad sense heritability were higher than that of narrow sense heritability while estimates of narrow sense heritability for infinity generation were greater than its F2 generation for all the traits. Considering the estimates of heritability and genetic advance at once suggested that only simple selections might be enough for further improvement of traits such as cell membrane thermo-stability, stomatal conductance, transpiration rate, leaf firing, ear length, kernels per ear and grain yield per plant under both the condition. Grain yield per plant had positive and significant association with stomatal conductance, transpiration rate, ear length and kernels per ear while negative but significant with leaf temperature, cell membrane thermo-stability, leaf firing and 100-grain weight at both genotypic and phenotypic levels under both normal and heat-stressed conditions. Ear leaf area exhibited positive and negative association only at genotypic level with grain yield under normal and heat-stressed conditions, respectively. It can be concluded that traits like cell membrane thermo-stability, ear leaf area and kernels per ear may be given priority in breeding strategies for achieving improvement in maize grain yield under high temperature circumstances.
