on the root growth ABA then activate transcriptional factor (TF), particularly in ABA dependent path, such as CBF4 (C-repeat binding factor4) or HDG11. Consequently, these TFs will active their target genes downstream e.g. LEA3 or P5CS gene. The activated LEA and P5CS will cause root grow deeper and more lateral roots, leading to drought tolerance in plant. (Figure 1) II) Accumulation of ABA and its effect on stomatal closure Accumulation of ABA in the leaf apoplast, leading to increased ABA at the
phase 2 proteins which have evolved to defend against any harmful effects of ROS or any other reactive species. In normal physiological conditions, a balance is maintained between the ROS production and their detoxification by the appropriate antioxidants and phases 2 proteins. (Uttara, Singh, Zamboni & Mahajan, 2009). Oxidative stress can occur due too many pathological conditions, when the balance of prooxidants and antioxidants is disturbed oxidative damage could accumulate in proteins, lipids
Determinant: proteins, hormones, or signals that determine the cell’s fate. Epithelium: derived from the endoderm and ectoderm, the outermost layer a body formed a thin tissue. Extracellular Matrix: The mixture of components on the exterior of the cell; molecules that help surrounding cells and are secreted by the surrounding cells. G Proteins: A family of proteins that function as molecular switches and transmit signals from exterior to interior of the cell. Another name for these proteins includes
by binding to G-protein coupled receptors that increase the levels of cyclic AMP within nociceptors. Prostaglandins also reduce the threshold depolarization required for generating action potentials by phosphorylating a specific class of TTX-resistant sodium channels, TTX-R Na+, that are expressed only in nociceptors (Kidd & Urban, 2001). In addition, some nociceptors can be sensitized by the MAPK mediated pathway. MAPKs are normally inactive in neurons, but they become activated when they are phosphorylated

Pigments produced by microorganisms has been used to dye fabrics of different types. Talaromyces verruculosus produce a red colored pigment which is suitable to dye cotton and is harmless. Pigments from microorganisms give different types of shades of a color. For instance; Janthinobacterium lividum produce a pigment which gives purplish-blue shade to different types of fabrics. Thermomyces produce a yellow pigment used to dye number of fabrics specifically silk. NP2 and NP$ strains of Streptomyces
2007). According to Betania et al. (2000), it is the last stage of leaf development. The senescence process is started by the breakdown of chloroplast (Gepstein, 2004). Next, it is followed by macromolecules catabolism for example nucleic acids, proteins, and lipids (Ulker et al., 1997). Final stage for leaf senescence is the degradation of mitochondria and nuclei (Gan and Amasino, 1997; Lim et al., 2007). Nutrients released by leaf senescence for example nitrogen, phosphorus, and minerals will be
Airway epithelial cells line the airway where they represent the first contact with inhaled insults including asthmagens (22). Airway epithelial cells express a variety of pattern recognition receptors (e.g., toll like receptors (TLRs) and protease activated receptors (PARs)) that interact with microbial components and initiate innate immune responses via cytokine, chemokine or small molecule release (21). Airway epithelial activation can lead to local activation of dendritic cells (DC; (20)) or group
Re: Research Assistant Dear Jason Geijskes, Please accept my application for the above-mentioned position as advertised on the http://seek.com.au website on 5 May 2010. My interest in working with a leading agribusiness industry together with the job responsibilities you have mentioned inspired me to apply for this position. My qualifications and skills that I believe will be important for this position are briefly discussed bellow for your kind consideration. Degree in biological science
Melanoma is an aggressive form of skin cancer that has a high potential of metastasis, where the exact time point of its progression to metastasis is difficult to detect (Somasundaram and Herlyn, 2012). It is well known that once an early stage in situ skin cancer is surgically removed or cured, metastasis is unlikely. However, once the cells acquire the characteristics to metastasise, a good prognosis becomes hard to achieve. Rates of metastasis after removal increase with increasing invasion depth
Antimicrobial peptides (AMP), also known as host defense peptides (HDPs), exist extensively in all classes of life, contributing not only on immune responses mostly to bacterial infections, also modulating inflammatory response by regulating cytokine, chemotaxis, apoptosis and wound healing. Human HDPs have three major components, namely human α-, β-defensins (HADs and HBDs), and cathelicidin (LL-37). HDPs have a broad spectrum of activity against gram-positive and -negative bacteria, fungal species
Bacillus anthracis (anthrax) is a bacterium that infects organisms through sporulation. Bacillus anthracis is can be aerobic (needs oxygen) or, facultative anaerobic (does not require oxygen). It is also a gram positive bacterium that can be found in the soil of humid and damp climates (Hicks, 2012). The bacterium is part of the species Bacillus Cereus (Koehler, 2009). It is known to infect life forms four different ways. Infection can be caused through digestion, eating food that is contaminated
therapeutic vaccine open a new horizon for better control of disease by improving the cellular immune arm against virus proteins expressed in host cells (5). Among different therapeutic vaccine strategies including virus based vectors, peptide vaccine, whole bacterial vectors, recombinant DNA vaccine, protein based vaccine has its special situation in HPV related diseases therapy. Protein-based vaccines are capable of generating CD8+ T-cell responses either on humoral immune response in vaccinated animals
Serratia marcescens, a Gram-negative bacillus, was originally and solely considered a biological marker in the medicinal industry, due to its highly natural red pigment: Prodigiosin (Hejazi and Falkiner, 1997). The pigment has numerous roles within bacteria, which can be further translated into the pharmaceutical and medical domain. This bacterium naturally occurs in water, soil, on plants as well as in humans and animals (Khanafari et al, 2006), where it is deemed an opportunistic pathogen. S.marcescens
