1. Competition effects on growth of individual trees were examined for 4 years in aggrading, mixed-clone stands of trembling aspen ( Populus tremuloides Michx.) at the Aspen-FACE free-air CO 2 and O 3 enrichment facility in northern Wisconsin, USA. During each growing season stands received one of four combinations of atmospheric [CO 2 ] (ambient vs ∼ 56 Pa) and [O 3 ] (ambient vs ∼ 1·5 × ambie...

Altogether 164 poor families who had children of normal and subnormal weight and height were studied in Bogota, Colombia. Physical growth was found to be positively associated with expenditure on food, sanitary conditions in the home, mother's age, birth interval between surviving children, level of parental newspaper reading, aspirations for children, and socioeconomic status. Physical growth ...

The malononitrilamide FK778 is a novel immunosuppressive agent with antiproliferative activities. To gain insight into the molecular mechanism of FK778-mediated growth inhibition, we analyzed cells which differ in their p53 status and functionality of retinoblastoma protein (pRb). FK778 acted as a broad inhibitor of cell proliferation independent of the p53 or pRb status. However, the mechanism...

Twenty eight term small for gestational age (SGA) infants and 18 term appropriate for gestational age (AGA) infants were studied prospectively to assess bone mineral density and cord serum zinc concentrations. Growth and nutritional status were evaluated, and bone mineral density was measured by dual energy x ray densitometry of the lumbar spine. Cord serum zinc, parathyroid hormone, osteocalci...

Background & Aims: Malnutrition is defined as nutritional disorders or unfavourable health status that can be the result of overconsumption or underconsumption of one or more nutrients. The causes of malnutrition are complex, multidimensional, and population specific. United Nations Children’s Fund (UNICEF) has adapted a conceptual framework for facilitating researchers in determining the cause...

Birth weight remains one of the most important measures we have of the health status of a population, and is a strong predictor of both neonatal mortality and morbidity. It reflects maternal nutritional status and fetal growth rates in the antenatal period. Although a large number of physiological and pathological variables can affect the growth rate, for most cases of growth-restricted fetuses...

Salinity is one of the major environmental stresses that limit plant growth and productivity. Glasswort (Salicornia herbacea L.) is one of the native halophytic plants of Iran that widely spread in salt areas. The purpose of this study was to determine the physiological and growth responses of S. herbacea to salinity stress. Plastic pods (15 cm diameter, 20 cm height) with the Silica sand bed w...

Three levels of lysine (90, 100 and 110% of Ross requirement) and of pyridoxine (3, 6 and 9 mg kg-1) were used in a 3 × 3 factorial experiment to investigate the growth and blood antioxidant ability of broilers under high ambient temperature. None of the dietary supplements affected the weight gain during the starter and grower periods. Although no significant differences were detect...

The insulin-like growth factor axis is highly responsive to nutritional status and may be involved as one of the underlying mechanisms through which caloric restriction could affect cancer risk. High levels of circulating insulin-like growth factor (IGF)-I, or IGF-I relative to IGF binding protein (IGFBP)-3 have been related to various human cancer types. In a group of 87 postmenopausal women, ...
