Does intravenous administration of recombinant tissue plasminogen activator for ischemic stroke can cause inferior myocardial infarction?

Recombinant tissue plasminogen activator (rTPA) is one of the main portions of acute ischemic stroke management, but unfortunately has some complications. Myocardial infarction (MI) is a hazardous complication of administration of intravenous rTPA that has been reported recently. A 78-year-old lady was admitted for elective coronary artery bypass graft surgery. On the second day of admission, she developed acute left hemiparesis and intravenous rTPA was administered within 120 minutes. Three hours later, she has had chest pain. Rescue percutaneous coronary intervention was performed on right coronary artery due to diagnosis of inferior MI, and the symptoms were resolved. © M. Almasi et al. 2016 Licensee PAGEPress, Italy

Atherosclerosis in patients with endometriosis

Endometriosis refers to endometrial tissue implantation including stromal and epithelial tissue outside the uterus. It is an often painful disorder that involves the ovaries and fallopian tubes. The association between endometriosis and atherosclerosis is interesting. The present study was conducted to assess the Doppler findings of the carotid artery in patients with and without endometriosis. In this study that included 30 patients with endometriosis and 30 control subjects, all patients underwent carotid ultrasonography, and the measurement of intima-media thickness (IMT) was done in the distal common carotid artery, proximal to the origin of the carotid bulb, and finally, we compare the IMT in two groups. This study revealed that there are no differences in the IMT between patients with and without Endometriosis. © Copyright A.H. Habibi, et al., 2019

Reduction Of Humic Substances In Water By Application Of Ultrasound Waves And Ultraviolet Irradiation

Humic substances mainly humic acids constitute the major fraction of natural organic matter in water supplies. They play an important role in the formation of harmful disinfection by products. Degradation of humic acids by means of ultraviolet radiation and ultrasonic irradiation processes was investigated in a laboratory-scale batch photoreactor equipped with an 300 W immersed-type medium-pressure mercury vapour lamp and sonoreactor with low frequency (42 kHz) plate type transducer at 170 W of acoustic power with emphasis on the effect of various parameters on degradation efficiency. Experiments were performed at humic acids initial concentrations varying between 2.5-10 mg/L. Oxidation of humic substances has been followed over time by measuring total organic carbon and UV absorbance in 254 nm and 436 nm. Initial results indicated a strong capacity of photolysis for degradation of humic substances. The results also showed that ultrasonic alone cannot be an efficient method for degradation of humic substances in comparison with UV process. The maximum degradation efficiency of humic substances after 90 min of irradiation, however, was only 5.7% and reached a maximum value of 9.5% after 300 min of irradiation. It was found that total organic carbon can be removed effectively by photolysis. It was also found that lower concentrations of humic substances favor the humic substances degradation. Also, the experimental results indicated that the kinetics of ultrasono-oxidation and photo-oxidation processes fit well by pseudo-first order kinetics

Biocontrol potential of Trichoderma harzianum in controlling wilt disease of pistachio caused by Verticillium dahliae

Verticillium wilt caused by Verticillium dahliae, is one of the most devastating diseases in pistachio orchards in the world including Iran. In search for an eff ective non-chemical strategy for the management of this disease, we evaluated the biocontrol potential of Trichoderma harzianum isolates obtained from the rhizosphere of healthy pistachio trees in diff erent locations of the Kerman province of Iran against V. dahliae under laboratory and greenhouse conditions. Dual culture tests in the laboratory were conducted in a completely randomized design using 72 T. harzianum isolates. Twenty isolates showed the highest in vitro antagonistic activity. Th e results indicated that all 20 isolates were capable of inhibiting the mycelial growth of V. dahliae signifi cantly. Among them, isolates Tr8 and Tr19 were the most eff ective by 88.89% and 85.12% inhibition, respectively. Extracted cell free metabolites of all eff ective isolates also inhibited the growth of V. dahliae in the culture medium signifi cantly. According to the results, isolates Tr4 and Tr6 inhibited fungal pathogen growth by 94.94% and 88.15% respectively, through production of non-volatile metabolites. In the evaluation of volatile metabolites, isolates Tr5 and Tr4 were the most eff ective by 26.27% and 24.49% growth inhibition, respectively. Based on the results of the in vitro experiments, the fi ve most eff ective isolates were selected for evaluation under greenhouse conditions for their biocontrol potential in controlling Verticillium wilt of pistachio. Results of the greenhouse, (in vivo) experiments were positive and indicated that the occurrence of wilt disease in plants treated with the antagonists alone or in combination with pathogenic fungus was lower than in plants inoculated with pathogen alone. Th e overall results of this study suggest that Trichoderma fungal antagonist may be an eff ective biocontrol agent for the control of Verticillium wilt of pistachio

Association between the initial total bilirubin level and the clinical outcome in patients with ST-segment elevation myocardial infarction undergoing primary PCI

Background: Clarification is needed as regards the relationship between the total bilirubin level and the outcome of primary percutaneous coronary intervention (PCI) in patients with ST-segment elevation myocardial infarction (STEMI). Methods: Between April 2015 and April 2016, consecutive patients with STEMI who underwent primary PCI were prospectively enrolled in a primary PCI registry. The patients� demographics, initial total bilirubin levels, procedural characteristics, and in-hospital and 6 months� major adverse cardiac events were assessed. Results: A total of 95 patients who underwent primary PCI were enrolled in the study. The mean bilirubin level was 1.04 mg/dL with a standard deviation of 1.154. We evaluated the relationships between the median of the initial total bilirubin level, the thrombolysis in myocardial infarction (TIMI) flow grade after PCI and following PCI, 6 months� follow-up complications, the amount of the peak troponin and CK-MB levels, the amount of mitral regurgitation, the ejection fraction, and electrocardiographic changes including ST resolution and the Q-wave formation after primary PCI. Except for the levels of troponin and CK-MB, there were no relationships between the initial total bilirubin level and the other end points. Conclusions: Recent studies have shown that the serum total bilirubin level is independently associated with short-term outcomes in patients with STEMI. We found a direct relationship between the total bilirubin level and the peak levels of troponin and CK-MB after primary PCI. This outcome is consistent with other studies; nonetheless, we found no such relationships vis-à -vis the other end points. This result may be due to our small patient population. © 2019, Iranian Heart Association. All rights reserved
