Although RB1 was the first turnor suppressor gene identified, its role during retinal development is poorly understood. We first attempted to determine this by performing in vivo misexpression studies in the post-natal rat retina. Retroviral lineage analysis revealed that clone size in pRB-infected eyes was significantly reduced when compared to control eyes. This suggested that pRB has a role ...

This paper presents the mechanical and microstructural characteristics of a lightweight aggregate geopolymer concrete (LWAGC) synthesized by the alkali-activation of a fly ash source (FA) before and after being exposed to elevated temperatures, ranging from 100 to 800 °C. The results show that the LWAGC unexposed to the elevated temperatures possesses a good strength-to-weight ratio compared wi...

The research reported herein studied the permeability of concrete containing recycled-concrete aggregate (RA), superfine phosphorous slag (PHS), and ground granulated blast-furnace slag (GGBS) with and without stress. Test results showed that the chloride diffusion coefficient of RA concrete (RAC) without external loads decreased with time, and the permeability of RAC is much lower than that of...

AIMS We investigated the spectrum of yeasts isolated, and compared the epidemiological and laboratory characteristics of women carrying vulvovaginal Candida albicans with those carrying yeasts other than C. albicans. METHOD Between April and June 2001, 5802 consecutively received genital swabs from women were plated onto Candida ID chromogenic media (BioMerieux). Blue colonies were reported a...

The research investigates the effects of super plasticizer and molarity of sodium hydroxide alkaline solution on the workability, microstructure and compressive strength of self compacting geopolymer concrete (SCGC). SCGC is an improved way of concreting execution that does not require compaction and is made by complete elimination of ordinary Portland cement content. The parameters studied wer...

BACKGROUND Fixed orthodontic appliance (FOA) increases the cariogenic microorganisms of mouth including candida. The aim was to evaluate the pharmacodynamic effects of some antibacterial drugs in combination with most applicable antifungal agents on candida isolated from patients with FOA. METHODS Three antifungal agents (amphotericin B (AMB), ketoconazole (KET), and itraconazole (ITZ)) and t...

Concrete is considered as a non-homogeneous material and from mesoscopic point of view constituted three main phases, namely aggregates, mortar matrix interfacial transition zone (ITZ). To investigate the damage process concrete materials at mesoscale due to mechanical loading, an explicit numerical model with full representation phases required. this end, in work, Python code developed generat...

Crumb rubber incorporation is widely deemed to deteriorate the compressive strength of concrete. One dominant reasons for this reduction known as inferior bonding or weak interfacial transition zones (ITZ) between crumb and hardened cement paste. While Styrene-butadiene (SBR)latex being used a agent in concrete manufacturing, SBR latex usage holds potential compensate from incorporation. This s...

The interfacial transition zone (ITZ) has a significant negative impact on the structural performance of concrete. This can be ameliorated by introducing mineral additions into In this study, different forms (degree circularity) coarse aggregates and three contents (10 %, 15 % 20 %) addition (natural pozzolan) were used to prepare ordinary article aims determine optimal effective mixture (the b...
