Morphological changes in garlic (Allium sativum L.) microbulblets during dormancy and sprouting as related to peroxidase activity and gibberellin A3 content.

The aim of this work was to study the physiological mechanisms of dormancy and sprouting during post-harvest of garlic (Allium sativum L.) microbulblets produced by meristem culture of garlic seed cloves. The morphological changes occurring in garlic microbulblets were assessed from harvest till sprouting in relation with peroxidase activity and levels of gibberellins.

Systemic lupus erythematosus (SLE) in childhood: analysis of clinical and immunological findings in 34 patients and comparison with SLE characteristics in adults.

Objective: To define the pattern of disease expression in patients with childhood onset systemic lupus erythematosus (SLE).

Methods: Prospective analysis of clinical manifestations and immunological features of 34 patients in whom the first manifestations appeared in childhood from a series of 430 unselected patients with SLE.

Results: Thirty one (91%) patients from the childhood onset group were female and three male (9%) (ratio female/male, 10/1, with no difference compared with the adult onset group).

Dermatoglyphics of the Chorote indians and their relationships with other inhabitants of the Gran Chaco.

The present report deals with digital and palmar dermatoglyphics of a sample of 98 Chorote indians, collected in the north of Argentina, in the Gran Chaco region. Bimanual dimorphism was observed in males and females, both in finger and in palmar variables. Significant differences between sexes appear only in digital ridge counts and in the combined incidence of the four pattern types the Chorote, in general, show low sexual dimorphism.
