The work aimed to evaluate the antibacterial activity of Phragmanthera capitata (Loranthaceae) extracts harvested from 03 host plants (Psidium guajava, Cirus sinensis and Theobroma cacao) traditionally used in the treatment of a wide spectrum of diseases. The phytochemical screening of the extracts was determined using standard reference methods. The antibacterial activity of the extracts was evaluated by disk diffusion and liquid microdilution methods on 07 bacterial isolates. Qualitative phytochemical analysis indicated the presence of flavonoids, tannins, sterols, phenols and polyphenols in all extracts of P. capitata. The evaluation of the antibacterial activity showed that the extracts from the stems and haustoria of P. capitata collected from the three host plants are more active than the leaves for all the strains tested. This study shows that P. capitata despite its pernicious character could be a source of useful compounds for the fight against bacterial diseases.

Background: Percutaneous Coronary Intervention (PCI) is the preferred method of revascularization in Acute ST Elevation Myocardial Infarction (STEMI). Aim: Our aim was to study the clinical profile and outcomes of patients who underwent PCI for STEMI at tertiary cardiac centre of Bangladesh. Methods: It is a retrospective, single centre study, performed at Bangabandu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh. All patients who underwent PCI for STEMI from November 2017 to July 2019 were enrolled in this study. All the data were collected from hospital registry and cath lab records. Results: The Study showed that out of 232 patients who presented with STEMI, 74.5% were male with average age of 57.39 years. The mean time of presentation after onset of symptom/s was 17.5 hours. About 66% patients presented in less than 12 hours of symptoms onset, 21% presented at 12-24 hours of symptoms onset and 13% patients presented late. Primary PCI was done in 87% of patients. Almost all patients (98.2%) underwent coronary artery stenting with drug eluting stents. Multivessel PCI during index procedure was done in 7 patients. TIMI III flow following PCI was achieved in 97% cases. Average LVEF at discharge was 44.73%. There were 8 deaths, all after Primary PCI. In-hospital mortality rates for patients presenting with and without cardiogenic shock were 38.46% and 1.59% respectively. The overall mortality rate was 3.98%. Conclusion: This study has reemphasized that PCI is effective in the management of STEMI cases in Bangladesh with improving mortality rates and decreasing complications. Minimizing the delayed presentation after the onset of symptoms should be one of the prime focuses for effective management of STEMI.

Wheat as an important staple food crop that is facing serious threat by increasing the phenomenon of salinity in the vast area worldwide. Due to climate change, more arable lands are going to be depended on irrigation which causes raising of salinity in the soil where then affect negatively on seed germination and growth of plants. Araz, is one of the used wheat cultivar in Iraq and Kurdistan where it was tested for its salt tolerance level by using salt solutions 0.01, 0.02 and 0.05 mol L-1, which answer to 0.58, 1,17 and 2,92g -1, and comparing these solutions as TDS (Total Dissolved Solids) to Electrical Conductivity (Soil Extract) EC(dS/m) for salt tolerance classification. The results showed significant effects of salt level 0,01 molL-1 on germination parameters except for seed water uptake. By increasing salt levels to 0.02mol and 0.05molL-1 the effects are negatively increased. What is concerning the effect of salt levels on growth parameters, the obtained results indicated that generally and without exception negatively effects of salt levels on growth parameters but. There were no difference effects between salt levels 0.01mol/L and 0.02molL-1on fresh weight of radicle, while increasing salt levels to 0.02 molL-1 up to0.05 molL-1the effects on growth were more severe. Salt level 0.05 molL-1 which is equivalent to TDS range 2,000-5,000 mgL-1 and it is answer to 3,0 -7,5 EC (dS/m , seen as not tolerance for cultivation wheat cultivar Araz.

Wheat is the most widely grown crop in the world and provides 20% of the daily protein and calories for 4.5 billion people. It is the second most important food crop in the developing world after rice. Charmo, Maroof and Alla are a new promising rust-resistant wheat varieties were have been tested for their salinity tolerance through seed water uptake, (germination percentage and germination mean), as well as growth of radical and plumule. The varsities was tested for their salt tolerance level by using salt solutions concentration levels with a control, 0.01, ,0.03.0,05, 0.07, and 0.09 molL -1, which are answer to 0.0, 0.58,1.75,9.2 ,4.01 and 5.26 gL -1,that symbolized as C0,C1,C2,C3,C4and C5. The results showed significant effects of varsities on water uptake, germination percentage germination mean time, wet and dry radical, but not significant effect on radical number and length as well as plumule length and wet dry plumule. What is concerning the effects of salt levels on germination parameters and growth of varieties, we noted significant effect of salt on germination mean, germination percentage, radical and plumule length as well as on wet radical weight. And the interaction between varsities and salt levels, the result has shown significant effect of interaction between varsities and salt levels on dry radical. Salt levels from C3 have indicted to have significant effect on germination on wet radical but not significant effect on water uptake, dry radical, as well as on wet and dry plumule. The results of the effect of varieties on germination and growth parameters showed that charmo and maroof are better than Alla. The study showed that Charmo and Maroof are toleration C2 respect but Alla dose not that is why it cannot be recommended to be used in soil with EC 0.80–2.50 which answers to C2 that is equivalent to 456–1425 mgL-1 but Charmo and Maroof have more tolerance at this level respectively.
