Brauer, Elizabeth - - 2010
There is considerable confusion about N use efficiency (NUE) in the plant literature. We would like to propose the simple and ubiquitous definitions described by Good et al. (2004) as a starting point for studies of NUE. Based on this terminology, there is evidence from breeding programs for variation in ...

The Enemy Release Hypothesis predicts that exotic plants gain an advantage over native competitors by losing their natural enemies while invading new regions. However, this assumes that those enemies reduced the performance of these invaders in their native ranges, and this may not be true if an invader is highly ...

Floral nectary structure, nectar production, and carbohydrate composition were compared from petals ("inner tepals") and sepals ("outer tepals") of Lilium Asiatic hybrid 'Tresor' (Liliaceae). The six nectaries each occupied a narrow furrow bordered by two convergent ridges extending adaxially from the petal and sepal base. Each sepal nectary furrow was ...

We investigated the structure and dynamics of the multi-stemmed understory shrub Lindera triloba (Sieb. et Zucc.) Blume over 3 years in an old-growth coniferous forest, and quantitatively evaluated the factors affecting the ramet production, growth, and survival. Most genets sprouted continuously and exhibited multiple-stemmed structures with a few large and ...

Species of Echium from the Canary Islands represent an adaptive radiation of plants involving evolutionary changes in habitat and life form. Alongside these changes, evolutionary transitions of the sexual system have occurred: approximately one quarter of Echium species from the Canary Islands are dimorphic for gender, paralleling other adaptive radiations ...

Alterations of root anatomy have been largely ignored as potential mechanisms for phosphorus-mediated control of arbuscular mycorrhizal colonization. However, at least three anatomical traits including the proportion of root length with a suberized hypodermis, the distribution of hypodermal passage cells, and the proportion of root volume as intercellular air space ...

A new arbuscular mycorrhizal fungal species of the genus Glomus, Glomus indicum (Glomeromycota), forming small, hyaline spores in hypogeous aggregates is described and illustrated. The spores are globose to subglobose, (17-)32(-52) [micro]m in diameter, rarely egg-shaped, oblong to irregular, 17-38 [micro]m x 19-13 [micro]m. The single spore wall of G. ...

Accurate identification of many red algae to the species level using only morphological characters can be difficult. The emerging field of "molecular-assisted alpha taxonomy" can greatly alleviate this issue. In this approach, a large number of specimens are sequenced for a standard DNA marker as a first step to genetic ...

Alder-dominated riparian forests represent only a small proportion of the landscape in central-interior British Columbia. However, they possess a suite of attributes that may allow them to function as refugia for canopy macrolichens. These include their deciduous habitat, their location in moist nutrient receiving sites, and their distribution as narrow ...

We evaluated the hypothesis that the modified population density of Aquilegia formosa Fisch. ex DC. (Ranunculaceae) resulting from the introduction of Sitka black-tailed deer (Odocoileus hemionus sitkensis) in the Haida Gwaii archipelago affects the pollination and reproductive performance of this herbaceous species. We compared the population density, pollination, and reproductive ...

This study examined the effect of the calcium channel blocker ruthenium red (RR) on developmental programmed cell death (PCD) and perforation formation in leaves of the aquatic lace plant (Aponogeton madagascariensis (Mirbel) H. Bruggen). Plant immersion experiments were conducted using various concentrations (0, 10, 20, 30, and 40 [micro]mol*[L.sup.-1]) of ...

A 12-year old girl was brought to the Dhaka Hospital of ICDDR,B with diarrhoea. Incidentally, the parents provided a history of repeated episodes of pallor and jaundice since she was two and half years old. Three of her family members had similar problems. History, clinical examination, and laboratory findings of ...

This article reports the results of a qualitative study conducted in two villages of Matlab to explore the cultural dimensions of depression. Participants included adult men and women with and without a history of depressive episode (n=42), formal and informal healthcare providers (n=6), and caregivers (n=2). Adults (n=10) with a ...

This study estimated the levels and differentials in nutritional status and dietary intake and relevant knowledge of adolescent girls in rural Bangladesh using data from the Baseline Survey 2004 of the National Nutrition Programme. A stratified two-stage random cluster-sampling was used for selecting 4,993 unmarried adolescent girls aged 13-18 years ...

To explore beliefs relating to diet, work, and HIV/AIDS among the Busoga of rural southeastern Uganda, a cross-sectional survey of 322 adults was conducted in 2007 in Mayuge district, Uganda. Of these adults, 56 were HIV-infected, 120 had a family member with HIV/AIDS, and 146 were in households without HIV-infected ...

Improving maternal health is one of the Millennium Development Goals of the United Nations. Despite the efforts to promote maternal and neonatal care to achieve this goal, the use of delivery care remains below expectations in Burkina Faso. This situation raises the question of the quality of care offered in ...
Maddah, Mohsen - - 2010
This cross-sectional study was conducted to investigate the prevalence and predictors of overweight and obesity by location of residence among randomly-selected 2,577 urban school girls aged 12-17 years in Rasht, Iran. Data on age, frequency of skipping breakfast per week, physical activity, hours of television viewing, self-perception about body condition, ...

There is currently no public financial system that fully covers enteric fever suspects in China. This study aimed at documenting the level of access to definitive diagnostic procedures, especially haemoculture, for these patients and examining the effect of health insurance on access to such care. A hospital-based cross-sectional study was ...

This study was undertaken to determine the genetic diversities of Giardia intestinalis isolated in Thailand. G. intestinalis cysts were collected from stool samples of 61 subjects residing in Bangkok or in rural communities of Thailand with and without gastrointestinal symptoms. All the cyst samples gave positive tpi amplicons (100% sensitivity), ...

In-house contamination of drinking-water is a persistent problem in developing countries. This study aimed at identifying critical points of contamination and determining the extent of recontamination after water treatment. In total, 81 households were visited, and 347 water samples from their current sources of water, transport vessels, treated water, and ...
