Pulmonary Arteriovenous Malformations Incidentalloma in a 10-Years-Old Child.

Pulmonary Arteriovenous Malformations (PAVMs) are structurally abnormal vascular communications between pulmonary arteries and pulmonary veins, which bypass the normal capillary bed and cause a low resistance right-to-left shunt with refractory hypoxemia. Generally, PAVMs were congenital, most commonly associated with (Hereditary hemorrhagic teleangiectasia (HHT). The age of diagnosis is very variable, range neonatal to adulthood, mostly diagnosed in the first 3 decades of life and clinical manifestations occur later in life generally.

α-Tomatine and resistance of tomato cultivars toward the nematode,Meloidogyne incognita.

Susceptible and resistant tomato cultivars were assayed for root tomatine concentrations at different developmental times. No correlation between high tomatine levels and resistance towardMeloidogyne incognita was apparent. In plants infected with nematodes, tomatine in the roots was the same as in uninfected controls.

Effects of cotton condensed tannin, maysin (Corn) and pinitol (soybeans) onHeliothis zea growth and development.

Maysin, a flavone glycoside from corn silks, inhibits ingestion, and thus growth, ofHeliothis zea (Boddie) larvae. Pinitol from soybeans inhibitedH. zea growth by the same mechanism.

Growth inhibitors in tomato (Lycopersicon) to tomato fruitworm (Heliothis zea).

Several compounds that retard the larval growth of the tomato fruitworm,Heliothis zea (Boddie) have been isolated and identified from tomato leaves,Lycopersicon esculentum Mill. The major allelochemics are α-tomatine (I), chlorogenic acid (II), rutin (III), and a new caffeyl derivative of an aldaric acid (IV). The isolation, analyses, and toxicity of these compounds toH.
