Amiodarone (AM) is a potent antidysrhythmic agent which can cause potentially lifethreatening pulmonary fibrosis, and N-desethylamiodarone (DEA) is a metabolite of AM that may contribute to the toxicity of AM in vivo. Recent evidence has implicated the involvement of the renin-angiotensin system (RAS) in the initiation and progression of amiodarone-induced pulmonary toxicity. In cultured HPL1A ...

Tomato leaves or cotyledons expressing the Cf-2 or Cf-9 Cladosporium fulvum resistance genes induce salicylic acid (SA) synthesis following infiltration with intercellular washing fluid (IF) containing the fungal peptide elicitors Avr2 and Avr9. We investigated whether SA was required for Cf gene-dependent resistance. Tomato plants expressing the bacterial gene nahG, encoding salicylate hydroxy...

a method for determination of juglone in leaves and hulls of pterocarya fraxinifolia was developed, based on rp-hplc. this compound was extracted from leaves and hulls by chloroform refluxing about 2 hours. the chloroform was evaporated under low pressure at   50 ºc to produce a dry residue. the remained materials were dissolved in acetonitrile to be used for determination of this compound. app...

the total nitrogen content of three barley cultivars: cehada capa (resistant at 25ac), cl 1243 (resistant at 5°c) and rika 1 (susceptible at all temperatures) to puccinia hordei was determined and compared in healthy and infected plants at 5° and 26°c. the results indicate that the total nitrogen content of cv. cehada capa leaves was greater than that of cl 1243 and rika 1 and that of cl 12...

BACKGROUND This study aimed to evaluate the relationship between cigarette smoking and coronary atherosclerotic burden, volume and composition as determined in-vivo by grayscale and virtual histology (VH) intravascular ultrasound (IVUS). METHODS AND RESULTS Between 2008 and 2011, (VH-)IVUS of a non-culprit coronary artery was performed in 581 patients undergoing coronary angiography. To accou...

Marine heat waves (MHWs), prolonged discrete anomalously warm water events, have been increasing significantly in duration, intensity and frequency all over the world, associated with a variety of impacts including alteration ecosystem structure function. This study assessed effects current future MHWs on Mediterranean seagrass Posidonia oceanica performance, also testing importance thermal env...

Abstract Background The purpose of this study was to use the MTT test assess cytotoxic effects different extracts Convolvulus pluricaulis leaves in vitro . leaf ethanolic extract has been demonstrated trigger apoptosis on HepG2 cancer cell lines, implying anti-cancer activity. Methods cells were grown culture DMEM and incubated with concentrations plant extracts. Survival rates quantified by as...

Orchid is one of the largest groups flowering plants that are in great demand by society. Besides, various flowers with a long vase life, price orchids also stable and affordable. Phalaenopsis Dendrobium most popular types orchids. To anticipate this, orchid cultivation needs to be improved. However, not always accompanied effort disease prevention, particularly those caused viruses. The virus ...

ABSTRACT Infection of Nicotiana obtusifolia plant introduction (PI) #555573 by the downy mildew pathogen Peronospora tabacina resulted in a compatible interaction, in which P. tabacina penetrated and freely colonized host leaf tissue. This interaction became incompatible 5 to 6 days later, with the appearance of necrotic lesions (NLs) and inhibition of pathogen growth and subsequent sporulation...
