Chlororespiration is involved in the adaptation of Brassica plants to heat and high light intensity.

Two species of Brassica were used to study their acclimation to heat and high illumination during the first stages of development. One, Brassica fruticulosa, is a wild species from south-east Spain and is adapted to both heat and high light intensity in its natural habitat, while the other, Brassica oleracea, is an agricultural species that is widely cultivated throughout the world. Growing Brassica plants under high irradiance and moderate heat was seen to affect the growth parameters and the functioning of the photosynthetic apparatus.

The relationship between the levels of salivary cortisol and the presence of xerostomia in menopausal women. A preliminary study.

Unlabelled: Xerostomia is a particularly frequent occurrence among menopausal women, and is often associated with depression.

Objectives: To evaluate the relationship between unstimulated salivary flow rate and the presence of xerostomia, and to determine the levels of salivary cortisol and its relationship with xerostomia.

Study Design: Thirty women were selected from patients attending the Department of Medicine and Buccofacial surgery, and formed into two groups, study and control.
