regenerative endodontic procedure is introduced as a biologically based treatment for immature teeth with pulp necrosis. successful clinical and radiographic outcomes following regenerative procedures have been reported in landmark case reports. retrospective studies have shown that this conservative treatment allows for continued root development and increases success and survival rate of the ...

One of the most severe symptoms caused by compatible plant-virus interactions is systemic necrosis, which shares common attributes with the hypersensitive response to incompatible pathogens. Although several studies have identified viral symptom determinants responsible for systemic necrosis, mechanistic models of how they contribute to necrosis in infected plants remain scarce. Here, we examin...

splenic infarction occurs due to occlusion of splenic vessels that leads to splenic tissue ischemia and necrosis. there are several reports regarding splenic infarction in patients with acute myelogenous leukemia (aml). herein, we report a case of acute promyelocytic anemia (aml-m3) who presented with abdominal pain and splenic infarction.

Ditylenchus dipsaci and Fusarium oxysporum f. sp. medicaginis synergistically affected the mortality and plant growth of Ranger alfalfa, a cultivar susceptible to stem nematode and Fusarium wilt. The nematode-fungus relationship had an additive effect on mortality and plant growth of Lahontan (nematode resistant and Fusarium wilt susceptible) and of Moapa 69 (nematode susceptible and Fusarium w...

BACKGROUND One of the main challenges in skin flap surgery is tissue ischemia and following necrosis. The present study compares the effects of fibroblast growth factors 1 and 2 on increasing cutaneous vasculature, improving ischemia, and preventing distal necrosis in ischemic skin flaps in rat model. METHODS Thirty rats were allocated into 3 groups (n=10) and 2×8 cm dorsal rando...

Transmission of Corynebacterium insidiosum (McCull.) Jensen (cause of bacterial wilt in alfalfa) by the stem and bulb nematode Ditylenchus dipsaci (Kiihn) was demonstrated by Hawn (3) . Disease development in plants where D. dipsaci was the vector was comparable to that in the controls where wilt was induced by the root-ball soak method devised by Cormack, Peake and Downey (1) . Furthermore, th...

widespread use of nanosilver can be led the contamination of aquatic environment and impact on living organisms such as fishes. we investigated histopathological changes in the gills tissue of caspian roach fingerlings after two weeks exposure to sublethal concentrations of nanosilver. following one and two weeks exposure, necrosis, shortening of secondary lamellae, edema, destruction of epithe...

Hunt et al. (2) and Norton (4) showed that the northern root-knot nematode, Meloidogyne hap/a Chitwood, increased the incidence of bacterial wilt in alfalfa. Hunt et al. (2) also f o u n d t h e b a c t e r i a l wilt organism, Corynebacterium insidiosum (McCuU) H. L. Jens., in plant tissue that had been inoculated only with the bacteria. This would indicate that the role of M. hapla is somethi...
