Sinorhizobium meliloti cells were engineered to overexpress Anabaena variabilis flavodoxin, a protein that is involved in the response to oxidative stress. Nodule natural senescence was characterized in alfalfa (Medicago sativa) plants nodulated by the flavodoxin-overexpressing rhizobia or the corresponding control bacteria. The decline of nitrogenase activity and the nodule structural and ultr...

to study the effect of planting dates and genistein application on nitrogen content and nodulation of three annual medic species (medicago polymorpha cv. santiago m. rigidula cv. ragidula, and m. radiata cv. radiata), an experiment was conducted during 2005-2006 in the research farm of faculty of agriculture, shahed university, tehran. the treatments were arranged as split split plot in a rando...

S (PH D THESIS) Involvement of auxin distribution in root nodule development of Lotus japonicus (Graduate School of Agriculture, Laboratory of Plant Gene Expression, RISH, Kyoto University) Kojiro TAKANASHI Legumes (Fabaceae) constitute the third largest plant family with around 700 genera and 20,000 species. Legume plants form root nodules through symbiosis with a soil microbe called rhizobia....

background: dirofilariasis is a common helminthic parasitic disease in both domestic and wild animals around the world, with canines as the principal reservoir host and mosquitoes as the vector.  human dirofilariasis has been reported from many parts of the world, including africa, australia, the americas, europe, and asia. case report: a 40 year old woman from abadan city southwest of iran ref...

conclusions for the first time to our knowledge, we have reported a severe retropharyngeal and upper mediastinum cellulitis, probably due to the fna procedure in an immunocompetent young woman. case presentation a thirty-five-year-old female was admitted to hospital with hoarseness, laryngeal stridor and dyspnea without fever that emerged about 3 days after a first diagnostic fna. after the pro...

Objective: Explore the practical clinical significance and correlation of voice handicap index (VHI) for vocal polyps and vocal nodules, and further validate practicality of VHI. Methods: VHI of vocal cord polyp group (n = 35), vocal nodule group (n = 29), and control group (n = 22) was surveyed respectively. The VHI investigation included three categories of function (F), physiology (P) and em...

Legumes enter into a symbiotic relationship with nitrogen-fixing rhizobia, leading to nodule development. Two main types of nodules have been widely studied, indeterminate and determinate, which differ in the location of the first cell division in the root cortex, and persistency of the nodule meristem. Here, we compared the control of auxin transport, content, and response during the early sta...

The occurrence of thyroid nodules increases with age [1]. In geographical areas with a normal iodine intake, approximately 10% of the population develops a palpable thyroid nodule. This proportion increases in areas with insufficient iodine intake. Non-palpable thyroid nodules are usually diagnosed by a neck echography carried out for various reasons and are 5-10 folds more common than palpable...

Symbiotic nitrogen fixation is sensitive to dark chilling (7 degrees C-15 degrees C)-induced inhibition in soybean (Glycine max). To characterize the mechanisms that cause the stress-induced loss of nodule function, we examined nodule structure, carbon-nitrogen interactions, and respiration in two soybean genotypes that differ in chilling sensitivity: PAN809 (PAN), which is chilling sensitive, ...

The differentiation of valvular interstitial cells (VICs) to a myofibroblastic or osteoblast-like phenotype is commonly found in calcific valvular stenosis, although the molecular-level mechanisms of this process remain poorly understood. Due to the role of the Rho pathway in various vascular diseases and in the expression of a myofibroblast phenotype, the present study was inspired by the hypo...
