In this survey, effective factors in little leaf disease on trees were studied in different pistachio orchards in Kerman province. Little leaf disease is the most serious disease of pistachio in Iran. Affected trees reduced growth rates. The first symptoms of little leaf disease are those of nutrient deficiency: a slight yellowing and shortening of the needles and reducing of shoot growth. New ...

The aim of investigation was to determine the effects of aspect (north and south) on some morphological [plant height (cm), number of stems per plant, main stem diameter (mm), number of leaves per main stem, petiole length (cm), leaflet length (cm), leaflet width (cm), leaf: stem ratio] and chemical [crude protein (%), crude cellulose (%), calcium (%), phosphorus (%), potassium (%) and magnesiu...

functional mitral regurgitation (mr) results from left ventricular remodeling, leaflet tethering or tenting. coronary artery disease is one of the important causes of functional mr due to tethering. detection of functional mr and its severity are important factors in patient prognosis. there are different methods for detection of functional mr and its severity, including anterior mitral leaflet...

prolapsed mitral valve syndrome is a common, benign disorder with prevalence of %0.3-6 in population. this syndrome also is known as barlows syndrome and flaapy mitral valve syndrome. prolapsed mitral valve is the dropping of one or two mitral valve leaflet(s) into the left atrium during ventricular systole. this malformation leads to incomplete closing of mitral valve and regurgitates the bloo...

OBJECTIVES Ischemic mitral regurgitation results from annular dilatation, leaflet tethering and leaflet flattening. Undersized annuloplasty corrects annular dilatation but worsens leaflet tethering and flattening. This exacerbation of abnormal leaflet geometry may contribute to poor repair results for ischemic mitral regurgitation (IMR). Using a sheep model of IMR, we hypothesized that posterio...

length to width) to indicate leaflet shape. He also defined leaflet shape index at 2.6 to differentiate between Two gene pairs are known to affect leaflet shape in soybean [Glybroad and narrow leaflet shape in Japanese cultivars cine max (L.) Merr.], but only two categories of leaflet shape are routinely used to characterize soybean germplasm. Very little informaand found that broad leaflet is ...

BACKGROUND Computational simulation using numerical analysis methods can help to assess the complex biomechanical and functional characteristics of the mitral valve (MV) apparatus. It is important to correctly determine physical contact interaction between the MV apparatus components during computational MV evaluation. We hypothesize that leaflet-to-chordae contact interaction plays an importan...
