Inoculation of Pochonia chlamydosporia triggers a defense response in tomato roots, affecting parasitism by Meloidogyne javanica.

Pochonia chlamydosporia is a soil-dwelling fungus and biological control agent of nematodes, active ingredient in commercial bionematicides. The fungus is also endophytically associated with the roots of several plant species, promoting their growth and inducing systemic resistance. In this study, different pathways and tomato defense metabolites were studied to identify mechanisms induced by P.

[Nephrotic syndrome. What is new since the 1988 study?].

The authors make a retrospective review of 53 new cases of Nephrotic Syndrome followed up in the Nephrology Unit from November 1988 to March 1994, bearing in mind the evaluation of casual changes of the disease standard regarding a previous study of 1988. Epidemiological, clinical, therapeutical and evolutional aspects were studied. Forty-four cases of primary Nephrotic Syndrome (83%) were identified, 61.

[Mechanical ventilation near large centers. The experience of a perinatal care unit].

A retrospective study of the newborns who were submitted to mechanical ventilation at the Neonatal Intermediate Care Unit was made between July 1991 and June 1994. Mechanical ventilation in such a unit should be transitory and not exceed 24 hours. Information concerning pregnancy, labour, neonates, type of ventilation and its problems was gathered.

[Histopathologic study of primary glomerulopathies: retrospective analysis of 197 renal biopsies (1985-1987)].

The histopathological prevalence of primary glomerular diseases in patients aged 14 to 70 years (105 males, 92 females) was analysed: 140 (71%) were aged from 14 to 35 years and 57 (29%) were older than 35 years, the difference being significant (p less than 0.001). The following data were found at our Nephrological Unit: the prevalence of focal glomerular sclerosis was 37.
