    Radio Frequency Identification (RFID) technology has been expanded to be used in different fields that need automatic identifying and verifying of tagged objects without human intervention. RFID technology offers a great advantage in comparison with barcodes by providing accurate information, ease of use and reducing of labour cost. These advantages have been utilised by using passive RFID tags. Although RFID technology can enhance the efficiency of different RFID applications systems, researchers have reported issues regarding the use of RFID technology. These issues are making the technology vulnerable to many threats in terms of security and privacy. Different RFID solutions, based on different cryptography primitives, have been developed. Most of these protocols focus on the use of passive RFID tags. However, due to the computation feasibility in passive RFID tags, these tags might be vulnerable to some of the security and privacy threats. , e.g. unauthorised reader can read the information inside tags, illegitimate tags or cloned tags can be accessed by a reader. Moreover, most consideration of reserchers is focus on single tag authentication and mostly do not consider scenarios that need multi-tag such as supply chain management and healthcare management. Secret sharing schemes have been also proposed to overcome the key management problem in supply chain management. However, secret sharing schemes have some scalability limitations when applied with high numbers of RFID tags. This work is mainly focused on solving the problem of the security and privacy in multi-tag RFID based system. In this work firstly, we studied different RFID protocols such as symmetric key authentication protocols, authentication protocols based on elliptic curve cryptography, secret sharing schemes and multi-tag authentication protocols. Secondly, we consider the significant research into the mutual authentication of passive RFID tags. Therefore, a mutual authentication scheme that is based on zero-knowledge proof have been proposed . The main object of this work is to develop an ECC- RFID based system that enables multi-RFID tags to be authenticated with one reader by using different versions of ECC public key encryption schemes. The protocol are relied on using threshold cryptosystems that operate ECC to generate secret keys then distribute and stored secret keys among multi RFID tags. Finally, we provide performance measurement for the implementation of the proposed protocols.Ministry of higher education and scientific research, Baghdad-Ira

    Objective: Iron disorder and abnormal expression of hepcidin play important roles in many diseases, but it is still unclear in type 2 diabetes mellitus (T2DM).  Current study aimed to assess iron, ferritin and hepcidin levels in plasma of with or without T2DM and evaluated increased body iron stores as risk factor for developing T2DM. Methods: Plasma samples were collected from 88 participants, who were categorized into 2 groups based on the presence or absence of T2DM. Demographics and general health parameters were recorded. Chemiluminescence microparticle immunoassay and enzyme-linked immunosorbent assay were used to detect iron, ferritin and hepcidin concentrations. The geometric mean±SD of the plasma level of hepcidin, ferritin, iron and insulin among T2DM comparing with that of healthy controls were evaluated. Results: Plasma ferritin and hepcidin levels in T2DM group were higher than in the control group (P < 0.05). The geometric mean ± SD of hepcidin and ferritin for T2DM were 41.1±23.3 μg/l and 227.2±156.1 Å‹g/L respectively;   higher than the 15.2±2.3 μg/l and 114.4±60.4 Å‹g/l of controls respectively. There was a significant associated between high level of plasma hepcidin (OR=2.75) and ferritin (OR=2.24); with T2 DM. Conclusion: In conclusion: the regulation of body iron, an essential but also toxic element is strictly controlled by a small peptide hormone hepcidin. The present data demonstrated that the higher hepcidin level in diabetic patients may be due to that higher ferritin, the elevated hepcidin might have adaptive value through down-regulated iron absorb and play an important role in pathogenesis of T2 DM.                                 Peer Review History: Received 20 January 2019;   Revised 25 February; Accepted 3 March, Available online 15 March 2019 Academic Editor: Dr. Gehan Fawzy Abdel Raoof Kandeel, Pharmacognosy Department, National Research Centre, Dokki, 12622,  Giza, Egypt, [email protected]  Received file:        Reviewer's Comments: Average Peer review marks at initial stage: 6.5/10 Average Peer review marks at publication stage: 8.5/10 Reviewer(s) detail: Dr. Tanveer Ahmed Khan, Hajvery University, Lahore, Pakistan, [email protected] Dr. A.A.

    Background and objective:  Gingival crevicular fluid (GCF) affords a exceptional window for investigation of periodontal condition as the levels of inflammatory mediators, which consequences owing to the increased local destruction of connective tissue structural elements. This study aimed to explore the interleukin 1β (IL-1β)) levels in the human gingival sulcus in healthy normal people; and the effect of host factors as age , gender, type of tooth used in pro-inflammatory biomarkers. Methods: Eighty seven patients, 54 (62.1%) female and 33 (37.9%) male (aged 12–34 years; mean 19.58±4.4 years), participated in this study. Each subject underwent a session on professional oral hygiene and received oral hygiene instructions. Gingival crevicular fluid (GCF) sampling was conducted (baseline). GCF was collected from the Central incisor, the Lateral incisor, the Canine, the First premolar and the second premolar in this study.  Results: In total, the mean±SD of central incisor IL-1β was 32.16±4.83 pg/ml, with a mode equal to 28.01 pg/mL, the median was 32.71 pg/mL, and ranged from 20.98 to 41.25 pg/ml with the 75% interquartile range (IQR) equal to 35.94 pg/ml. For males the mean±SD of central incisor IL-1β was 31.6±5.51 pg/ml VS 32.5±4.4 pg/ml of females. For the lateral incisor, canine, first premolar, second premolar: Conclusion: This study provides the upper limit of normal values ​​for interleukin 1β (IL-1β) levels for subjects aged 12–34 years in the GCF. These upper limits of normal values ​​will guide dentists in Yemen when they consider the diagnosis of periodontal disease, as well as its role during orthodontic tooth movement where they play important role in osteocyte activities (e.g, osteoclasts and osteoblasts), and will provide useful baseline data for future studies of interventions against periodontal disease, and teeth movement by orthodontics appliances, in Yemen.                           Peer Review History: Received: 1 September 2022; Revised: 11 October; Accepted: 6 November, Available online: 15 November 2022 Academic Editor: Dr. Emmanuel O.
