to study the effects of halopriming and hydropriming in overcoming salt and drought stress in corn (zea mays l.),two experiments were separately conducted at shahrood university of technology. seed treatments consisted ofcontrol (untreated seeds), soaking in distilled water for 32 h (hydropriming), and soaking in 50 mmol solution ofcacl2 for 16 h (halopriming). germination and early seedling gr...

common burnet (poterium sanguisorba) is a perennial herb from rose family (rosaceae) which is used to construct pastures. the studied plant can resist against freezing, cool and drought. the present study was conducted to study the seed germination parameters of common burnet in different thermal treatments as completely randomized design in 4 replications in 2013. treatments involved the effec...

Despite theoretical and physical studies implying that cell-extracellular matrix adhesion geometry governs the orientation of the cell division axis, the molecular mechanisms that translate interphase adhesion geometry to the mitotic spindle orientation remain elusive. Here, we show that the cellular edge retraction during mitotic cell rounding correlates with the spindle axis. At the onset of ...

The difficulty in predicting the consequences of interactions between different cytokine networks has increased with the expansion of the T helper (Th) cell universe and the discovery of numerous B lymphocyte-derived cytokines. Consequently, it is now difficult to conceptualize a straightforward view of the contribution of these disturbances to the pathogenesis of primary Sjögren's syndrome (SS...

An essential requirement for providing secure services in wireless sensor networks is the ability to establish pairwise keys among sensors. Due to resource constraints on the sensors, the key establishment scheme should not create significant overhead. To date, several key establishment schemes have been proposed. Some of these have appropriate connectivity and resistance against key exposure, ...

Research on intestinal bacteria began around the end of the 19th century. During the last 5 decades of the 20th century, research on the intestinal microbiota made rapid progress. At first, in my work, I first developed a method of comprehensive analysis of the intestinal microbiota, and then I established classification and identification methods for intestinal anaerobes. Using these methods I...

Fibroblasts are fairly easily isolated from a variety of tissues, in this case skin. The cells are fast growing and can be rapidly expanded from small samples. They are suitable for behavioral, functional, biochemical, and genomic studies. Skin fibroblast cultures are started from explants in which the epidermis is enzymatically removed to prevent contamination of the fibroblasts with epidermal...
