rosa hybrida l. is an important commercial cut flower. salicylic acid (sa) and calcium chloride (cacl2) act as endogenous signal molecules responsible for growth parameters in plants. the aim of this study was to evaluate the effects of preharvest sa and cacl2 treatments in extending the vase life of cut rose flowers. therefore, a factorial experiment based on completely randomized design with ...

AIMS Previous studies have shown that prodromal angina (PA) occurs frequently in acute myocardial infarction (MI) patients. However, the potential benefits of PA on ischaemic myocardial damage remain unknown. METHODS AND RESULTS One-hundred and fifty-four patients with acute ST-segment elevation MI successfully treated with primary percutaneous coronary intervention (PPCI) were prospectively ...

this study was conducted to evaluate the effect of drought stress on 22 durum wheat genotypes. different characteristics such as grain weight per spike, plant biomass, 100 grain weight, free proline content in leaves, and percentage of cell membrane damage were studied in greenhouse and laboratory conditions. genotypes were sown under normal irrigation and moisture stress conditions. in stress ...

Abstract Schefflera plant is propagated and grown under greenhouse cultivation, most of these greenhouses are low-cost. In the summer, heat generated in becomes a limiting factor for growth and, subsequently, limits production high-quality species conditions. The powder banana (B), orange (O), pomegranate (P) peels their combinations were added as soil supplementation at rates 8 16 g/pot to pot...

We investigated cytotoxic activity of antimicrobial peptides of different origin (both naturally occurring and synthetic), structure and known mechanisms of action against human histiocytic lymphoma cell line U937. The strongest cytotoxic activity against U937 cell line was shown by Pexiganan MSI-78, followed by Citropin 1.1, Protegrin 1 and a synthetic lipopeptide, N-α-palmitoyl-L-lysyl-L-lysi...

stability at > 40% [3]. A meta-analysis of CRC patients including 1,277 MSI-H patients showed that MSI-H cancers were associated with a better prognosis than MSS cancers [4]. In addition, MSI-H cancers have a lower incidence of lymph-node or systemic metastasis compared to MSS cancers. Furthermore, adjuvant 5-Fluorouracil systemic chemotherapy has been revealed to have no oncologic benefits in ...

The utilization of biogas as carbon source for the co-production of filamentous-like materials and syngas is proposed. Catalysts with different Ni:Al molar ratios, Al2O3 supports and preparation methods were synthesized. The suitability of the catalysts was analyzed considering activity, stability and carbon yield. Catalysts showed a good performance and similar results according to syngas comp...

The adaptive response of the genome protection mechanism occurs in cells when exposed to genotoxic stress due to the overproduction of free radicals via inflammation and infection. In such circumstances, cells attempt to maintain health via several genome protection mechanisms. However, evidence is increasing that this adaptive response may have deleterious effect; a reduction of antioxidant en...

Abstract In this study ameliorative effects of ascorbic acid (0.5 mM) on onion (Allium cepa L. cv. Red Azarshahr) under copper stress (Cu: 6.5 μM) were studied. Fresh weights of leaves and roots were reduced in seven week old plants under excess copper condition. Cu stress also reduced membrane stability index in leaves. There was a considerable increase in H2O2 content and lipid peroxidation i...
