BACKGROUND AND PURPOSE Hip resurfacing arthroplasty (RHA) is done in patients who often have a high preference for the method. This preference can influence the clinical outcome and satisfaction. We evaluated the potential influence of this preference bias. PATIENTS AND METHODS From an ongoing randomized trial comparing RHA with total hip arthroplasty, 28 consecutive patients (28 hips) who ha...

The 5' untranslated region (UTR) of retroviruses contain structured replication motifs that impose barriers to efficient ribosome scanning. Two RNA structural motifs that facilitate efficient translation initiation despite a complex 5' UTR are internal ribosome entry site (IRES) and 5' proximal post-transcriptional control element (PCE). Here, stringent RNA and protein analyses determined the 5...

The double-stranded RNA-activated protein kinase R (PKR) is a key regulator of the innate immune response. Activation of PKR during viral infection culminates in phosphorylation of the alpha subunit of the eukaryotic translation initiation factor 2 (eIF2alpha) to inhibit protein translation. A broad range of regulatory functions has also been attributed to PKR. However, as few additional PKR su...

RESURFACING HIP ARTHROPLASTY +*Hananouchi, T; *Sugano, N; *Nishii, T; *Sakai, T; **Miki, H;**Lee, SB; **Ohzono, K; *Yoshikawa, H +*Department of Orthopaedic Surgery, Osaka University Graduate School of Medicine [email protected] Introduction: Metal on metal resurfacing hip arthroplasty (RHA) has been getting popularity due to its concept of bone conservation, stability, and expected longevi...

RNA helicase A (RHA) is a multifunctional protein with established roles in chromatin regulation. The protein is conserved in worms, Drosophila, and mammals, but its role in worms has not been previously studied. We found that a deletion mutant lacking rha-1 has a temperature-sensitive defect in germline transcriptional silencing, consistent with RHA-1 having a function in transcription regulat...

Human papillomavirus can be detected by amplification of viral DNA. A novel one-step PCR (PM-PCR) was evaluated for amplification of a 117-bp fragment from the E1 region. It permitted ultrasensitive detection of all 25 known human papillomavirus genotypes from the beta-papillomavirus genus. The intra- and intertypic sequence variations of the 77-bp interprimer region were studied. Genotype-spec...

Rice Husk Ash (RHA) of three different particle size ranges (50 – 75 μm), (75 – 100μm) and (100 – 150μm) in 3, 6, 9 and 12 % by weight was reinforced with the aluminium alloy using stir cast route. The microstructure and mechanical properties of the fabricated composites were analyzed. The results reveal that the tensile strength, compressive strength and hardness of the aluminum alloy composit...

In this study, waste ash was utilized as a pozzolanic material in blended Portland cement in order to reduce negative environmental effects and landfill volume required to dispose of waste ash. The influence of waste ash, namely palm oil fuel ash, rice husk ash and fly ash on compressive strength and sulfate resistance in mortar were studied and evaluated by some accelerated short-term techniqu...

Soil stabilization has become a major issue in construction engineering and the researches regarding the effectiveness of using industrial wastes are rapidly increasing. The present experimental work briefly describes the suitability of the locally available Rice Husk Ash (RHA) to be used in the local construction industry in a way to minimize the amount of waste to be disposed to the environme...

The treatment of sulfate-bearing soil with calcium-based stabilizers such as cement or lime often results in ettringite formation, consequently leading to swelling and strength deterioration. Ettringite formation has negative environmental economic effects on various civil engineering structures. This study was conducted investigate the use different materials (nano–magnesium oxide (M), ground ...
