The activation of programmed cell death in the host during plant-pathogen interactions is an important component of the plant disease resistance mechanism. In this study we show that activation of programmed cell death in microorganisms also regul...

A well circumscribed ganglioneuroma affected a 6.5 cm section of the jejunum of a 6-week-old kitten (the first reported in a cat). Histologically the tumour was characterized by irregular bundles of nerve fibres, with Schwann cells and single or g...

A phylogenetic analysis of the genus Roccellina completed ten years ago was reexamined with computer programs for phylogenetic analysis now readily available. Two analyses were carried out: one that used the same data as that of a decade earlier a...

Context: Despite a strong rationale for trials of somatostatin analogs in the treatment of Graves' ophthalmopathy (GO), recent studies have provided conflicting results.Objective: The objective of the study was to determine whether octreotid...

Objective: Term labor is associated with global thinning of the myometrium. We hypothesized that a thickened myometrium at the time of preterm premature rupture of membranes (PPROM) predicts less myometrial wall stress and, consequently, a longer...
