During barley (Hordeum vulgare) seed development, phosphoenolpyruvate carboxylase (PEPC) activity increased and PEPC-specific antibodies revealed housekeeping (103-kD) and inducible (108-kD) subunits. Bacterial-type PEPC fragments were immunologically detected in denatured protein extracts from dry and imbibed conditions; however, on nondenaturing gels, the activity of the recently reported oct...

Light is vital to plant life, not only as an energy source for photosynthesis but also as an important environmental signal regulating development and growth. Light affects almost every stage of plant development (Kendrick and Kronenberg, 1994), including seedling development, which represents one of the most dramatic and best characterized processes (von Arnim and Deng, 1996). In Arabidopsis t...

OBJECTIVE To determine the perceptions and beliefs relating to unwanted pregnancy, family planning and abortion, and identify issues that can be leveraged to initiate positive attitudes towards family planning and abortion in the area. MATERIALS AND METHODS Focus group discussions (FGDs) and in-depth interviews (IDIs) were conducted in Amukpe, Delta State, Nigeria. A highly motivated and well...

What do the Atkins Diet and the traditional Japanese diet have in common? The Atkins Diet is low in carbohydrate and usually high in fat; the Japanese diet is high in carbohydrate and usually low in fat. Yet both work to promote weight loss. One commonality of both diets is that they both eliminate the monosaccharide fructose. Sucrose (table sugar) and its synthetic sister high fructose corn sy...

Two low equivalent weight perfluorosulfonic acid (PFSA) polymers (825 EW and 733 EW) were successfully electrospun into nanofibers by adding as little as 0.3 wt% of high molecular weight poly(ethylene oxide) as a carrier polymer. The electrospun fiber morphology transitioned from cylindrical filaments to flat ribbons as the total concentration of PFSA + carrier in solution increased from 5 wt% ...

In this paper, I bring out the contrasts between two different approaches to student learning: that of computational learning scientists and socio-cultural anthropologists, and suggest some implications and directions for learning research in MOOCs. Computational learning scientists see learning as a matter of imbibing particular knowledge propositions, and therefore understand teaching as a wa...

Abstract Background Water uptake is essential for seed germination. However, Gleditsia sinensis seeds have a water-impermeable coat, which beneficial its adaption to the environment, but prohibits germination without treatment. This feature may be associated with structure of coat. Thus, aim this research was identify and describe initial water site movement determine relationship between coat ...

Soil salinity affects a large part of the region in Iran. Salinity covers 12.5% oftotal area of the country. Priming of seeds in sodium chloride and water (hydro-priming)has been reported to be a simple technique for enhancing the seedling establishment andgermination performance in the seeds of many crops and small seeded grasses under thestress conditions. Therefore, the aim of this research ...

Vaccine-mediated prevention of primary HIV-1 infection at the heterosexual mucosal portal of entry may be facilitated by highly optimised formulations or drug delivery devices for intravaginal (i.vag) immunization. Previously we described hydroxyethylcellulose (HEC)-based rheologically structured gel vehicles (RSVs) for vaginal immunization of an HIV-1 vaccine candidate, a soluble recombinant t...

Design and development of novel drug delivery system (NDDS) has two prerequisites. First, it should deliver the drug in accordance with a predetermined rate and second it should release therapeutically effective amount of drug at the site of action. Conventional dosage forms are unable to meet these requisites. Niosomes are essentially non-ionic surfactant-based multilamellar or unilamellar ves...
