Private Information Retrieval (PIR) allows for retrieval of bits from a database in a way that hides a user’s access pattern from the server. However, its practicality in a real-world cloud computing setting has recently been questioned. In such a setting, PIR’s enormous computation and communication overhead is expected to outweigh any cost saving advantages of cloud computing. This paper pres...

Myelin components that inhibit axonal regeneration are believed to contribute significantly to the lack of axonal regeneration noted in the adult central nervous system. Three proteins found in myelin, Nogo, myelin-associated glycoprotein, and oligodendrocyte-myelin glycoprotein, inhibit neurite outgrowth in vitro. All of these proteins interact with the same receptors, namely, the Nogo recepto...

In [22] we showed that existing single-server computational private information retrieval (PIR) protocols for the purpose of preserving client access patterns leakage are orders of magnitude slower than trivially transferring the entire data sets to the inquiring clients. We thus raised the issue of designing efficient PIR mechanisms in practical set-

Intracerebroventricular (icv) injection of pirenzepine (Pir) 2 mg.kg-1 caused EEG spike discharges, which first appeared in amygdala or hippocampus and then in midbrain reticular formation and cortex. After that rabbits developed clonic convulsions. Injection (300 micrograms) into amygdala or hippocampus also produced EEG spike discharges Hemicholinium 3 (HC-3) 50-150 micrograms.kg-1 icv inhibi...

The Protein Information Resource (PIR) has been maintaining a database of curated protein sequence alignments since 1991. The collection includes superfamily, family and homology domain alignments. CLUSTAL V/W is used to generate multiple sequence alignments and ALNED, an interactive alignment editor, is used to check and correct them. The database has helped in classifying sequences, in defini...

The Post Implementation Review (PIR) is arguably the single most cost effective tool available for software process improvement. However to maximise the benefits, a methodology and supporting tools for the PIR are required. This paper examines the prerequisites for successful reviews and the key elements of the method. It then describes eight practical techniques (both qualitative and quantitat...

It is useful to support Byzantine robustness in a Private Information Retrieval (PIR) protocol so that any database operators that are being used cannot maliciously affect the records that a client is looking for. We analyze the problem of Byzantine servers in Goldberg’s IT-PIR protocol and relate the problem to the well known stag hunt game. To make this game more applicable, we expand it to i...

Effect of citrus pectin oligosaccharides produced by irradiation was studied on the ability to improve lipid metabolism and hypercholesterolemia in mice fed high cholesterol diets. A total of 35 mice were divided into 5 groups and fed the following diets for 6 weeks: normal diet (C), 0.5% cholesterol (CH), 0.5% cholesterol+5% non-irradiated pectin (P), 0.5% cholesterol+5% irradiated pectin at 2...

The present study evaluated in mice the possible modification of psychostimulant methamphetamine (MET) effects by co-administration of piracetam (PIR) and the development of behavioural sensitisation to the psychostimulant in the case of combined treatment. On the Day 1 mice were randomly allocated into 4 groups and control open field test was performed. On the Day 7, after 5 days without treat...
