Almost all current block-cipher-based MACs reduce their security to the pseudorandomness of their underlying block ciphers, except for a few of them to the unpredictability, a strictly weaker security notion than pseudorandomness. However, the latter MACs offer relatively low efficiency. In this paper, we investigate the feasibility of constructing rate-1 MACs from related-key unpredictable blo...

Recombinant baculoviruses derived from the Autographa californica nuclear polyhedrosis virus (AcNPV) are widely used to express heterologous genes in insect cells, but the use of the baculovirus expression vector system (BEVS) is hampered by slow and tedious procedures for the selection and separation of baculovirus-infected insect cells and for titer determination. Here we developed a new tech...

PURPOSE. Retinal degeneration initiated by loss of photoreceptors is the prevalent cause of visual impairment and blindness in industrialized countries. Transplantation of photoreceptor cells represents a possible replacement strategy. This study determined that identification of cell surface antigens can assist in enriching photoreceptor precursors for transplantation. METHODS. The expression ...

This paper looks at the management accounting and control system (MACS) changes in the Housing Authority of Fiji (hereafter HA) from the wider social and political dimensions. The HA has been set up to provide affordable shelter and mortgage finance for low and middle-income earners in Fiji. The subject organisation has been able to meet the demands of customers. Presently, the HA has been able...

BACKGROUND The original Manchester Acute Coronary Syndromes model (MACS) 'rules in' and 'rules out' acute coronary syndromes (ACS) using high sensitivity cardiac troponin T (hs-cTnT) and heart-type fatty acid binding protein (H-FABP) measured at admission. The latter is not always available. We aimed to refine and validate MACS as Troponin-only Manchester Acute Coronary Syndromes (T-MACS), cutt...

Disparate reports exist on the eosinophil chemotactic capacity of interleukin-8 (IL-8). We hypothesized that the difference is due to the methods used to purify eosinophils. We therefore compared the eosinophilotactic capacity of IL-8 on human cells isolated by Percoll (positive selection) vs. magnetic cell separation system (MACS) (negative selection). Discontinuous Percoll gradients were prec...

Ovarian primary mucinous adenocarcinomas (MACs) are refractory to conventional therapy. Biomarkers for ovarian MAC could facilitate prognosis and targeted therapy, but are not currently available. The expression of human epidermal growth factor 2 (HER-2) has been linked to enhanced survival of MAC patients and may hold potential as a biomarker, but this potential has not been sufficiently inves...

OBJECTIVE This study was carried out to investigate the correlations of the sperm DNA fragmentation index (DFI) with semen parameters and apoptosis, and to investigate the effects of density-gradient centrifugation (DGC) and magnetic-activated cell sorting (MACS) on reducing the proportion of sperm with DNA fragmentation and protamine deficiency. METHODS Semen analysis and a sperm DNA fragmen...

the satellite cells. Contaminating CD45+/Mac-1+/Sca-1+ cells were subsequently removed by MACS cell separation. Cell cycle analysis revealed that over 80% of the resulting myogenic cell population was in G0, indicating a high proportion of quiescent cells in the isolated population. RT-PCR analysis showed that the expression of three Kruppel-like factors (Klf) was increased in quiescent satelli...
