Life history and production of Caenis luctuosa (Burmeister) (Ephemeroptera, Caenidae) in two nearby reaches along a small stream
Population dynamics and production of C. luctuosa were compared in two reaches of the Agüera stream (northern Spain). This species showed univoltine winter life history in both sites. However, the start of the re...

Afforestation with Eucalyptus globulus and leaf litter decomposition in streams of northern Spain
To test the hypothesis that decomposition of leaf species in streams is influenced by afforestation with Eucalyptus globules, we compared decay rates, nutrient levels, fungal biomass and macroinvertebrate assembl...

Insulin-Like Growth Factor I, Its Binding Proteins 1 and 3, and Growth Hormone-Binding Protein in Children and Adolescents with Insulin-Dependent Diabetes Mellitus: Clinical Implications
Values of IGF-I after extraction, its binding proteins, and the high affinity GH-binding protein (BP) are not well established in pediatric patients with insulin-dependent diabetes mellitus (IDDM). We report d...

Decreased Expression of Placental Growth Hormone in Intrauterine Growth Retardation
During normal pregnancy, the levels of placental GH in the maternal circulation increase significantly until 35 wk of gestation. We have previously shown that these levels are significantly reduced in cases of...

PATIENTS WITH CONSTITUTIONAL DELAY OF GROWTH AND PUBERTY (CDGP) DO NOT EXHIBIT AN ABNORMAL PATTERN OF GROWTH HORMONE (GH) SECRETION, INDEPENDENT OF THEIR GROWTH VELOCITY (GV)
Children with CDGP exhibit a characteristic pattern of growth during their infancy and childhood. Some of these patients show a severe deceleration of growth velocity before puberty. Although some authors have...

Decomposition processes of Spartina maritima in a salt marsh of the Basque Country
Decomposition dynamics of aerial parts and root-rhizomes of Spartina maritima in a Basque Country salt marsh was studied, using litter bags placed on the soil surface and buried 10 cm below ground. Aerial parts o...

Breakdown of four leaf litter species and associated fauna in a Basque Country forested stream
Leaves of 4 species (Quercus robur, Castanea sativa, Corylus avellana and Pinus pinaster) were incubated in a forested headwater stream using bags (1 mm and 5 mm net size) and trays (5 mm net size). The type of t...

Surgical Ultrasonic Aspiration of Brain Tumors
In the last 10 years surgical ultrasonic aspiration has become established as a modern neurosurgical technique (2, 6, 7, 9, 13). The successful use of the ultrasonic aspirator system has suggested that this techn...
