OBJECTIVE Due to excessive production of free radicals and antioxidants evolved mechanisms against oxidative stress, infants are very vulnerable. As there was a significant relation between antioxidant levels and birth weight, we aimed verify this relationship. MATERIALS & METHODS In this descriptive analytical study we evaluated the antioxidant status of 40 healthy term newborns (gestation a...

BACKGROUND In 1990, the Iranian Ministry of Health implemented a health plan to increase mothers' knowledge of infant feeding using health workers and health volunteers. This study evaluates the effects of nutrition education on mothers' knowledge and whether increase in mothers' knowledge was associated with increase in growth of their children in Ardabil, Iran. METHODS A quasi-experimental ...

BACKGROUND One out of seven teenage girls in developing countries marries before the age of 15. While the fertility rate of teenage girls is high, the rate of contraceptive use remains low; therefore, this group of teenagers needs reproductive healthcare. This study was undertaken to explore factors influencing the use of contraceptives from the perspective of teenage women living in the city o...

Wetlands are subject to changes in soil moisture as a result of both short-term seasonal climate variations and long-term changes in regional water resource management, both of which can modify the dynamics of ground and surface water inputs. In the New Jersey Pinelands, forested wetlands that differ in both plant communities and soil structure occur along a topographic and hydrological gradien...

The impact of small-stature alkali bulrush (Bolboschoenus maritimus) and two hydroperiod treatments (early season raised water level or ambient water level) on mosquito production and water quality was studied in replicate 0.09 ha free water surface (FWS) treatment wetlands. Following reconfiguration of a 1-ha constructed wetland into a system with six replicate wetlands, bulrush was planted on...

The restoration project in the Hole-in-the-Donut of Everglades National Park in Florida, USA is to reestablish native wetlands by complete removal of the invasive plants and the associated soil. However, there is little information available about changes in properties of the newly formed Marl soils in restored wetlands. In this study, we measured soil physicochemical properties, soil enzymatic...

Livestock grazing can compromise the biotic integrity and health of wetlands, especially in remotes areas like Patagonia, which provide habitat for several endemic terrestrial and aquatic species. Understanding the effects of these land use practices on invertebrate communities can help prevent the deterioration of wetlands and provide insights for restoration. In this contribution, we assessed...

Riparian wetlands are temporarily or permanently inundated and/or water-logged zones along the margins of streams and rivers. They link permanent aquatic habitats with upland terrestrial habitats, and surface-water with groundwater. This chapter focuses on riparian wetlands associated with low-order tropical streams, which have been lesser studied than equivalent ecotones associated with large ...

Constructed wetlands are promising engineering technique that reproduce the conditions of the natural wetlands [1]. They have high water treatment capacity because of the intensive “work” of the plants and the microorganisms. Depending on the conditions various types of plants are growing: common reed (Phragmites australis), rush (Typha latifolia), iris, etc. (Fig. 1). These plants are stable t...
