With increased use of passive RFID tags, the need for secure lightweight identification protocols arose. HB+ is one such protocol, which was proven secure in the detection-based model, but shown breakable by man-in-the-middle attacks. Trusted-HB is a variant of HB+, specifically designed to resist man-in-the-middle attacks. In this paper, we discuss several weaknesses of Trusted-HB, show that t...

We propose a light-weight protocol for authentication of low-power devices. Our construc-tion PUF-HB merges the positive qualities of two families of authentication functions. PUFrepresents physically unclonable functions and fulfills the purpose of providing low-cost tamper-resilient challenge-response authentication. On the other hand, the Hopper Blum (HB) functionprovides...

background: beta thalassemia gene mutations are among common mutations in southwest iran. however, hemoglobin e (hb e) and hb e/β⁰ thalassemia account for a small number of hemoglobinopathies in iran. this is the first study to directly address the existence of hb e and consequently hb e/β⁰ thalassemia in southwest iran. methods: this retrospective study discovered seven cases of hb e/β⁰ thalas...

Several functional tests were performed to compare Hb A, Hb A2, and Hb Lepore Boston, which has a delta-beta crossover in the region of residues 87 to 116. Oxygen equilibrium curves determined by an automatic apparatus in 0.1 M potassium phosphate buffer, pH 7.0, at 20 degrees showed that the p50 was 5.8 mm Hg for Hb Lepore Boston, in contrast to 8.1 and 10.3 mm Hg for Hb A2 and Hb A, respectiv...

hepatoblastoma (hb) is a rare tumor of infancy and childhood manifesting with hepatomegaly and abdominal distention. it is seen with increased frequency in association with congenital hemihypertrophy and renal anomalies. metastases to other organs, including the lungs, lymph nodes and even ovaries is well known. but cerebral metastasis of this tumor, especially in the absence of metastasis to o...

congenital methemoglobinemia is a rare cause of cyanosis. we report a case of a girl, 17 years old with peripheral cyanosis and normal cardio-pulmonary system. she was diagnosed as a case of methemoglobinemia based on findings of polycythemia and hbm band on hemoglobin electrophoresis. we emphasize the importance of this rare entity in the differential diagnosis of cyanosis.

Toxoplasmosis is one of the most common zoonoses worldwide. The seroprevalence for T. gondii in human population from Brazil might range from 40 to 80%. The aim of this paper was to study the seroprevalence of T. gondii infection in children from age one to 15 living in a low socioeconomic community, named community of Jardim São Remo in the year of 2002. The community is located in the West ar...
