INTRODUCTION A triple antibiotic mixture of ciprofloxacin, metronidazole, and minocycline was used as an intracanal medicament in an attempt to disinfect the root canal system for revascularization of a tooth with a necrotic pulp. However, discoloration developed after applying the triple antibiotic mixture. METHODS Six weeks after a triple antibiotic paste had been applied to the root canal ...

water deficiency is one of the most important factors for limiting crop yield in arid and semiarid regions. symbiosis with a variety of microorganisms in these regions is one of the modern ecological approaches for sustainable agriculture to reduce damages caused by environmental stresses. symbiotic of arbuscular mycorrhizal fungi (am) with the roots of crops has shown positive effects on agric...

results significant differences were observed in the results of co-culture of nematodes larva and fungi after seven days. the most effective fungi against the nematodes larvae were cladosporium sp., trichoderma sp., fusarium equisetti, after seven days of incubation. materials and methods sheep feces were employed to provide the required third stage larvae source for the experiments. the nemato...

The grain weevil (Sitophilus granarius) caused symptoms of allergic rhinitis and asthma in two laboratory workers, one after exposure to weevil dust for only six months and the other after three years. The former worker also noticed sneezing when she was cooking with National Flour. Skin testing with extracts of the grain weevil faecal dust gave positive skin responses. The antibodies were succ...

Background and Aim: Tooth discoloration induced by endodontic sealers is an un-desired outcome of endodontic treatment that affects the esthetic appearance of the teeth, which is important especially in the anterior region. The aim of the present study was to compare the coronal discoloration caused by two frequently used resin-based sealers namely EasySeal and AdSeal. Materials and Methods: F...

during spring and summer of 2010 and 2012, several surveys were conducted in different vineyards in kohgiluyeh & boyer-ahmad (southwestern iran) and kerman (southeastern iran) provinces, with the aim of isolating and identifying fungi associated with grapevine decline diseases. the samples collected comprised diseased grapevines showing yellowing, defoliation, reduced growth, wilting, intervein...

Root-knot nematode penetration and morphopathlogy of the infection sites were studied in roots, stem and hypocotyls of Luffa cylindrica, L. and effect of combined inoculation of Vesicular Arbuscular Mycorrhizae (VAM) fungi included Glomus mossae, Glomus intraradices, G. fasciculatum, Acaulospora sp. and Meloidogyne incognita (Root-knot Nematode) were investigated. The maximum number and size of...
