BACKGROUND Quercetin, found abundantly in onion peel, has been known to have anticholesterol, antithrombotic and insulin-sensitizing properties. Here, we investigated the effect of quercetin-rich onion peel extract (OPE) on reactive oxygen species (ROS) production and antioxidative defense in obese woman. METHODS This study was randomized, double-blind, placebo controlled study. Thirty-seven ...

Several order preserving encryption (OPE) algorithms have been developed in the literature to support search on encrypted data. However, existing OPE schemes only consider a single encryption key, which is infeasible for a practical system with multiple users (implying that all users should have the single encryption key in order to encrypt or decrypt confidential data). In this paper, we devel...

Order-preserving encryption (OPE) allows encrypting without losing information about the order relation between the encrypted data items. Thus, the execution of compare, order and grouping operations can be done like on plaintext data. In particular it allows databases to do range queries over encrypted data, which is a useful feature especially for cloud databases that usually run in untrusted...

We discuss the operator product expansion (OPE) in the string theory on AdS3. In particular, we discuss the OPE among the primary fields in the spectrum recently proposed for the SL(2, R) WZW model, which describes the strings on the Lorentzian AdS3. For this purpose, we calculate the correlation functions of the primary fields with definite SL2 weights. Using these correlation functions, we st...

We consider a recent security definition of Chenette, Lewi, Weis, and Wu for order-revealing encryption (ORE) and order-preserving encryption (OPE) (FSE 2016). Their definition says that the comparison of two ciphertexts should only leak the index of the most significant bit on which the differ. While their work could achieve ORE with short ciphertexts that expand the plaintext by a factor ≈ 1....

We tested the electrical characteristics of an oligo phenylene ethynylene OPE molecule with one nitro side group, an OPE with two nitro side groups, and an OPE with no nitro side groups in our nanowell device. The OPE molecule with nitro side group s showed switching behavior with memory as well as nonreversible negative differential resistance NDR . Current-voltage I-V characteristics showed a...

The photophysical properties of two hybrid multichromophoric systems consisting of an oligophenylethynyl (OPE) scaffold decorated by 10 red or blue naphthalene diimides (NDIs) have been investigated using femtosecond spectroscopy. Ultrafast charge separation was observed with both red and blue systems. However, the nature of the charge-separated state and its lifetime were found to differ subst...

In this paper we study order-preserving encryption (OPE), a primitive in the database community for allowing efficient range queries on ecrypted data. OPE was suggested by Agrawal et al [1], and was throughly studied by Boldyreva et al [2]. In this paper we present a practical OPE scheme, which is a key-controlled algorithm, based on simple computation. A primary analysis shows that our algorit...

UNLABELLED To evaluate the possible effects of outpatient preoperative evaluation (OPE) for new surgical patients who will be inpatients, we conducted an observational study at a university hospital in The Netherlands. Various outcomes before and after the introduction of an OPE clinic were compared. The study population comprised all 21,553 elective adult inpatients operated on between January...
