Single wall carbon nanotubes are allotropes of carbon which can be viewed as graphene sheets wrapped around themselves forming a cylindrical structure. Due to their extraordinary electrical properties and their metallic/semiconducting behavior, single wall carbon nanotubes (SWCNTs) have been widely applied in electronic circuits and devices. However, many authors have confirmed that these electronic properties are not the identical for every single walled carbon nanotube; conversely, they are...
The kiwi (Apteryx) is a flightless bird endemic to New Zealand. Widely known as the elusive national symbol of New Zealand, the kiwi is an endangered species occupying areas of both the north and south islands of this South Pacific nation. Comparable to the size of a domestic chicken, this unique species belongs to an ancient group of birds called the ratites, commonly known for their lack of ability to fly. The flightless nature of the kiwi is especially notable since scientists have been...
ABSTRACT AIMS: The focal adhesion molecule paxillin localizes to cell adhesion sites where it mediates interactions between the actin cytoskeleton and the extracellular matrix. We previously demonstrated that paxillin was overexpressed in human lung cancer and identified somatic paxillin mutations in 9% of lung cancer. A murine in vivo xenograft model of the most common paxillin mutation (A127T) showed increased cell proliferation and invasive tumor growth establishing an important role for...

Ethylene (C2H4) is a gaseous hormone produced from bacteria, fungi and all parts of higher plants such as shoots, flowers, seeds, leaves, roots, and fruits (Pech et al., 2003, p. 247). Ethylene is a two carbon symmetrical compound with one double bond (CH2=CH2). Its molecular weight is 28.05, with freezing, melting, and boiling temperatures of -180°C, -169.5°C and -103.7°C respectively. It is a flammable and colourless gaseous compound (Arshad & Frankenberger, 2002, pp. 1-9)....
The purpose of this research project was to review the cross-linking techniques used to produce polyethylene pipes for domestic as well as other commercial applications. No matter how remarkable the properties of a plastic may be, it is the effectiveness of its applications that would make the plastic successful or unsuccessful, in the case of polyethylene it would be success. Polyethylene was first used in telephone cable insulation, however after its huge success it was then used in a wide...
This study analyses the effect of ultrasonic pre-irradiation treatment upon aqueous enzymatic extraction of essential oil from lemongrass, Cymbopogon citratus by comparing different irradiation time (0min, 5min, 10min, 15min), extraction process time (4hr, 6hr, 8hr) and conventional extraction method (steam distillation and hydrodistillation). Pectinase Ultra SP-L, a commercial enzyme were used in the aqueous enzymatic extraction of lemongrass essential oil. The essential oils extracted were...
Gluten triggers a t-cell mediated immune response from the body. T cells stands for Thymus- dependent because these cells are produced from stem cells in the thymus and then are stored in the thymus, spleen and lymph nodes, from which they are then sent out to other organs. T cells have receptors sensitive to antigens, related to immunoglobulins (antibody proteins), on the surface of specific other cells, and must come into close contact with the afflicted cell. B cells, which are made in...
Background: Idiopathic pulmonary arterial hypertension (IPAH) is a poorly understood debilitating disorder. There is a need for early diagnostic biomarkers to improve its poor prognosis. With proteomic techniques, profiling of the human plasma proteome become possible in searching for novel biomarkers. Methods: From a previous study, label free liquid chromatography tandem mass spectrometry (LC-MS/MS) was used to compare the plasma samples from eight IPAH patients and eight healthy controls....
Introduction Amphibians are members of the class Amphibia, subphylum Vertebrata, phylum Chordata. The class Amphibia includes frogs, toads, salamanders, newts and caecilians. Amphibians are characterized by a glandular skin without external scales, by gills during development (and in adulthood in some), and by eggs that may have jelly coats but develop without formation of extraembryonic membranes such as the amnion. Most amphibians also have four limbs. Limbs and lungs are adaptations for life...
