Introduction: Teaching renal physiology for undergraduatemedical students in an understandable way using methods whichimprove their deep learning has always been a problem. In thisstudy, Early Clinical Exposure (ECE) was used in teaching renalphysiology for the second year medical students in Shiraz MedicalSchool. This article aims to introduce and develop this programand also measure the attit...

Oxygen deficiency is commonplace in seeds, and limits both their development and their germination. It is, therefore, of considerable relevance to crop production. While the underlying physiological basis of seed hypoxia has been known for some time, the lack of any experimental means of measuring the global or localized oxygen concentration within the seed has hampered further progress in this...

The seeds of Spartium junceum contained a large quantity of lectin-like protein that did not appear to be either a hemagglutinin or active lectin. The cross-reactive material (CRM), like most legume seed lectins, was a tetrameric glycoprotein of about 130,000 M(r). The singlesized subunits of about 33,000 M(r) were not covalently associated. The amino acid composition was typical of legume lect...

in order to study the phenological and morphological characteristics, comparison of yield and yield components, correlation between traits and determination of the parameters affecting seed yield, a field experiment was carried out at the research farm of shahrekord university in 2007. ten lentil genotypes were compared by a randomized complete block design with three replications. the analysis...

For human food security, the preservation of 7.4 million ex-situ germplasm is a global priority. However, ex-situ-conserved seeds are subject to aging, which reduces their viability and ultimately results in the loss of valuable genetic material over long periods. Recent progress in seed biology and genomics has revealed new opportunities to improve the long-term storage of ex-situ seed germpla...

Arabinans and galactans are neutral pectic side chains and an important part of the cell walls of dicotyledonous plants. To get a detailed insight into their fine structure, various oligosaccharides were isolated from quinoa, potato galactan, and sugar beet pulp after enzymatic treatment. LC-MS(2) and one- and two-dimensional NMR spectroscopy were used for unambiguous structural characterizatio...

Crithmum maritimum L. (Apiaceae) is a perennial local oilseed halophyte. For a better understanding of the eco-physiology of salt tolerance at the germinative stage of this species, we investigate here the effects of nitrate, thiourea, and priming on its seed germination under saline conditions. Germination was strongly inhibited by increasing salinity. While nitrate supply was effective in all...

Background and objectives: Nigella sativa L. is one of the most important species in Iranian traditional medicine (ITM). According to ITM, the plant seeds can cause bronchospasm in patients with hot temperament; therefore it is recommended to process the seeds with grape vinegar before usage. This process may influence some components of the seeds; thus, in the present...

The studies on growth regulation in black gram cv. ADT (Aduthurai) 5 exhibited significant changes in growth, physiology and yield due to chemicals and plant growth regulators. Foliar application of NAA @ 40ppm at pre-flowering stage influenced growth characteristics by showing increased plant height, more number of branches, higher leaf area index and leaf area duration. But, with regard to ph...
