objective(s): the aim of the present study is to determine the effect of chloramphenicol (cap) on rat liver and small intestine. effect of phenobarbital (pb) on cap toxicity was also investigated.   materials and methods:   rats were received cap at doses of 0, 200, 400 and 600 mg/kg. another group was pretreated with 80 mg/kg pb 30 min prior to administration of various doses of cap. the exper...

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.

Background and purpose: Cancer is one of the major health challenges in the world. The efficacy of current treatments is low but their side effects are high. Cold atmospheric plasma (CAP) is a new modality for cancer treatment. This study aimed to compare the cytotoxicity effect of CAP on the cell line models of common cancers and normal cells. Materials and methods: In this experimental study...

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...

The electrocatalytic oxidation of captopril (CAP) was studied by modified carbon nanotubes paste electrode in the presence of isoproterenol (ISPT) using cyclic voltammetry (CV), chronoamperometry and square wave voltammetry (SWV). Also, the values of catalytic rate constant (k), and electron transfer coefficient (α) for CAP were calculated. The mechanism of CA electrochemical behavior at the mo...
