Biomarkers, including cytokines, can help in the diagnosis, prognosis, and prediction of treatment response across a wide range of disease settings. Consequently, the recent emergence of protein microarray technology, which is able to quantify a range of inflammatory mediators in a large number of samples simultaneously, has become highly desirable. However, the cost of commercial systems remai...

Bertino, Ferrari and Atluri (BFA) have recently presented a model for specifying and enforcing authorization constraints for Workflow Management Systems (WFMS). The model is comprehensive and exhibits strong properties such as (1) a language to express constraints, (2) formal notions of constraint consistency and (3) algorithms for role-task and user-task assignments. In this paper, we extend t...

Recently, IACR ePrint archive posted two fully homomorphic encryption schemes without bootstrapping. In this note, we show that these schemes are trivially insecure. Furthermore, we also show that the encryption schemes of Liu and Wang [6] in CCS 2012 and the encryption scheme of Liu, Bertino, and Xun [5] in ASIACCS 2014 are insecure either.

Paratuberculosis (PTB) is a major disease problem worldwide, and causes major economic losses in the dairy industry. Although PTB has been reported in Korea, no studies have been conducted to determine its prevalence and no program has been developed to control the disease. In this study, the sera of beef (n = 1,056) and dairy cattle (n = 1,105) from all provinces in Korea were tested to determ...

Objective: Sera from 186 sheep (93 rams and 93ewes) from Tabriz, North-West of Iran were evaluated for antibodies to Toxoplasma gondii using a commercial ELISA kit. Methods: The animals were divided into two age groups (< 2 years, and > 2 years). Results: Antibodies to T. gondii were found in 13 of 186 sheep (6.98%). Infection rate in ewes was higher than rams but this differe...

In this paper, we present a provably secure redactable signature scheme allowing to independently redact structure and content. We identify the problems when structure is not separated from content, resulting in an attack on the scheme proposed at VLDB ’08 by Kundu and Bertino. The attack allows for changing the semantic meaning of a given tree. We introduce a rigid security model, including co...

Labeling of food allergens in accordance with legal regulations is important to protect the health allergic consumers. The requirements for detecting foods involve adequate specificity and sensitivity identify very small amounts target complex matrices processed foods. In this work, one hundred commercial samples were analyzed walnut detection using three different methods: a sandwich enzyme-li...

Background: Erythropoietin, as a principal hormone promotes red blood cell production in bone marrow. Varieties of erythropoietin biosimilar are being produced by recombinant DNA technology in cell cultures. The detection or quantification of these molecules are being performed by diff erent methods which some of theme such as Western blot and enzymelinked immunosorbent assay (ELISA) require sp...

BACKGROUND The present recommendation for the serologic diagnosis of Lyme disease is a 2-tier process in which a serum sample with a positive or equivocal result by an enzyme-linked immunosorbent assay (ELISA) or immunofluorescent assay is then followed by supplemental testing by Western blot. Our laboratory has developed recombinant chimeric proteins composed of key Borrelia epitopes. These no...
