background: recently, botulinum neurotoxin (bont)-derived recombinant proteins have been suggested as potential botulism vaccines. here, with concentrating on bont type e (bont/e), we studied two of these binding domain-based recombinant proteins: a multivalent chimer protein, which is composed of bont serotypes a, b and e binding subdomains, and a monovalent recombinant protein, which contains...

The ELISA and an immunoblotting technique were used to study F38-type mycoplasmas - an important cause of contagious caprine pleuropneumonia - and a number of related mycoplasma species, subspecies, types or serogroups. Two-way ELISA cross-reactivity was demonstrated between five mycoplasmas, namely strain F38, Mycoplasma mycoides subsp. mycoides (LC strain), M. equigenitalium, M. primatum and ...

Routine serological diagnoses for leishmaniases, except in visceral cases, are performed using whole-parasite antigens. We used enzyme-linked immunosorbent assay (ELISA) to evaluate the performance of Leishmania infantum rHsp83 compared with L. major-like total promastigote antigen in the diagnosis of cutaneous (CL), mucosal (ML), and visceral leishmaniases (VL). ELISA-rHsp83 was significantly ...

The validity of markers in plasma of in vitro thrombolysis was investigated in 12 patients with extensive fibrinogen breakdown (greater than 80%, group 1) and in 12 patients with minimal breakdown (less than 20%, group 2). The patients were treated with 100 mg of recombinant tissue-type plasminogen activator (rt-PA) in the "Thrombolysis in Myocardial Infarction II" (TIMI II) trial. Cross-linked...

l-Alpha-acetylmethadol (LAAM) was recently approved as a substitute for methadone. LAAM, methadone, and their common metabolite, methadol, are extensively N-demethylated. The structural similarities of LAAM and its metabolites to methadone suggest that they may cross-react in methadone immunoassays. To test this hypothesis, drug-free urine was fortified with LAAM, norLAAM, dinorLAAM, methadol, ...

The serological relationship between the two vesicular stomatitis virus (VSV) strains Indiana (VSV-Ind) and New Jersey (VSV-NJ) were analyzed by using an enzyme-linked immunosorbent assay (ELISA). Immunoglobulin G responses, defined by their resistance to treatment with 2-mercaptoethanol, were assessed by ELISA by using sucrose gradient-purified VSV or purified VSV glycoproteins (G) as antigens...

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.

A total of 1935 migratory birds from 104 different species were captured in southeastern Sweden in 2005-2006 and tested for antibodies against West Nile virus (WNV). Overall, 46 birds (2.4%; binomial confidence limits, 1.8-3.2) were positive by blocking-ELISA, but only 2 (0.10%; binomial confidence limits, 0.0-0.4) had antibodies detectable by both blocking-ELISA and WNV neutralization test. EL...
