Introduction: Radiation therapy planning (RTP) is one of the clinical applications in which both CT scan and MRI are used. MR and CT images are applied to determine the target volume and calculation of dose distribution, respectively. In addition, using two imaging modalities increases the department workload and cost. In this study, an algorithm was presented to create synthet...

It is generally accepted that seedlings from large seeds are more tolerant to defoliation than those from small seeds due to the additional metabolic reserves present in the large seeds. However, information on the effects of amount of seed reserves (cotyledon removal) from seedlings resulting from large vs. small seeds on seedling growth and long-term survival in the field is limited. Five leg...

The effects of storage and deep desiccation on structural changes of DNA in orthodox seeds are poorly characterized. In this study we analyzed the 5-methylcytosine (m(5)C) global content of DNA isolated from seeds of common pear (Pyrus communis L.) that had been subjected to extreme desiccation, and the seedlings derived from these seeds. Germination and seedling emergence tests were applied to...

This work is aimed to use an eco-friendly water soluble gum (extracted from Fenugreek seeds) investigate its suitability in printing paste as thickening agent with natural dyes named; Safflower, Henna and Alkanet were used alternative solution for toxic, carcinogenic harmful problems resulted synthetic dyes. The addition of citric acid or sodium carbonate the using different values was examined...

Intact wild-type tomato (Lycopersicon esculentum cv. Moneymaker) seeds do not complete germination to the same percentage or at the same speed as intact ABA-deficient sitiens (sit") mutant seeds when seeds of both genotypes are imbibed on polyethylene glycol (PEG) solutions of -0 .3 to —1.5 MPa osmotic potential. However, if the thicker testas of wild-type seeds are removed (stripped) from the ...

Seed masting and production of empty seeds have often been considered independently as different strategies to reduce seed predation by animals. Here, we integrate both phenomena within the whole assemblage of seed predators (both pre and post-dispersal) and in two contrasting microsites (open vs. sheltered) to improve our understanding of the factors controlling seed predation in a wind-disper...

Dormancy breaking and germination requirements were determined for seeds of the eastern North American (eNA) species Sanicula canadensis, Sanicula gregaria and Sanicula trifoliata, and the data compared to those available for the European–Asian (EurA) congener Sanicula europaea. Seeds of the three eNA species had underdeveloped embryos that were physiologically dormant, i.e., morphophysiologica...

OBJECTIVES This study aimed to develop drugs from natural sources to overcome the side effects of many of synthetic drugs. Methanol extracts of both pericarp and seeds of Pleiogynium solandri were used to investigate antioxidant, hepatoprotective, and renal function protective, analgesic, and anti-inflammatory effects and to determine the chemical composition of the extract responsible for bioa...

Seeds of Balanites aegyptiaca stored for one year were germinated using cold and boiling water pre-treatments and different sowing orientations. Whole fruits were soaked in cold water for (18, 24 and 48 hours, respectively), while extracted sun dried seeds were immersed in boiling water for 7 minutes. Seeds of each treatment were sown in three orientations (seeds laid vertically with stalk end ...

Introduction Parsley (Petroselinum crispum) is one of herbs the most extensively used as a condiment for garnishing and seasoning, but also in perfumery, and in a larger extent in folk medicine. It is a biennial plant belonging to Apiaceae family (Simon and Quinn, 1988) [11]. Parts used in therapeutics are ripe fruits (seeds), root and aboveground parts of the plant. The curiosity is that parsl...
