A new biomaterial is presented which consists of a cellulose derivative--silanised hydroxyethylcellulose (HEC-SIL) and biphasic calcium phosphate (BCP). Rheological properties of the polymer itself and its mixture with BCP are pH-dependent. At pH 10-12 HEC-SIL is liquid and undergoes quick gellation at pH < 9. Similarly, the paste of HEC-SIL and BCP is fluid and injectable at higher pH and soli...

background: lipophosphoglycan 3 (lpg3) is required for the lpg assembly, a well known virulent molecule. in this study, the lpg3 gene of the lizard and mammalian leishmania species were cloned and sequenced. a three-dimensional structure (3d) for the target sequence was also predicted by comparative (homology) modeling. materials and methods: an optimization pcr amplification was performed on g...

The current research investigates the HEC based training for the University teachers in Pakistan and its impact on the performance on University teachers. The Higher Education Commission (HEC) in Pakistan seeks to improve the quality of teaching by University teachers. The Commission has initiated different forms of training according to the areas of expertise in order to improve skills and imp...

Repair of human endometrium after menstruation and preparation of the endometrium for implantation involves profound angiogenic changes. Vascular endothelial cell growth factor (VEGF) is a recently identified growth factor with significant angiogenic properties. Four species of mRNA encoding VEGFs were identified in human endometrium and myometrium. All species were present throughout the menst...

in this research between 3-dimensional and axisymmetric modeling for movement of nano-particles in passing through a aerodynamic lens, and also between these models and famous model of wang & liu was compared. for this purpose, output of nano-particles penetration, divergence angel, and nano-particle velocity with wang & liu model was compared. geometrical model used for aerodynamic lens compar...

Successful fertilization in plants requires the properly coordinated development of female reproductive tissues, including stigma, style, septum and transmitting tract. We have identified three closely related genes, HECATE1 (HEC1), HECATE2 (HEC2) and HECATE3 (HEC3), the expression domains of which encompass these regions of the Arabidopsis gynoecium. The HEC genes encode putative basic helix-l...

PURPOSE This study reported patient outcomes of chemotherapy-induced nausea and vomiting (CINV) prophylaxis for highly emetogenic chemotherapy (HEC) and moderately emetogenic chemotherapy (MEC) regimens and evaluated its adherence to acute-phase CINV prophylaxis in the Korean population subset of the Pan Australasian Chemotherapy Induced Emesis burden of illness (PrACTICE) study. MATERIALS AN...

Floods have become more severe and frequent as a result of climate change around the world, posing hazard to public safety economic development. This study investigates use distributed hydrological models in flash flood risk management small watershed Hazara, Pakistan, with goal improving Pakistan's early warning lead time. First, HEC-HMS model was built using geographic data river network's st...

backgrounds: evidence is accumulating to support disruption of tissue architecture as a powerful event in tumor formation. for the past four decades, intensive cancer research with the premise of “cancer as a cell based-disease” focused on finding oncogenes or tumor suppressor genes. however, the role of the tissue architecture was neglected. three dimensional (3d) cell cultures which can recap...

A scheme used in building models of three-dimensional objects through binocular and motion parallax analyses is presented. Some preliminary results in using the models for recognition are described, and a discussion of the major objectives summarizes the rationale of the work. The principal emphasis throughout the paper will be that effective vision requires flexible, domain-free, three-dimensi...
