Anti-P antibodies present in sera from patients with chronic Chagas heart disease (cChHD) recognize peptide R13, EEEDDDMGFGLFD, which encompasses the C-terminal region of the Trypanosoma cruzi ribosomal P1 and P2 proteins. This peptide shares homology with the C-terminal region (peptide H13 EESDDDMGFGLFD) of the human ribosomal P proteins, which is in turn the target of anti-P autoantibodies in...
The receptor for gp70 envelope glycoprotein of murine ecotropic leukemia virus is essential for virus entry into the host cell and has been recently demonstrated to function as a cationic amino acid transporter. In the experiments reported herein, we compared the gene expression of the murine ecotropic retroviral receptor (ERR) and its human homolog (H13) in rapidly proliferating cells versus r...
In this study, the hardness and wear behaviour of carburized and boronized AISI 8620 steels have been studied. The boronizing treatment increased the hardness of AISI 8620 steels from 395 HV0.1 to a maximal 1610 HV0.1 compared to the carburized steels and also significantly improved its wear behaviour. From obtained results, it can be concluded that boronizing is very effective surface hardenin...
Abstract Forging dies are crucial in forging to manufacture accurate workpieces. These generally made of AISI H steel series and hardened tempered medium carbon alloy steel. Dies processed by using high-speed milling + polishing or electrical discharge machining polishing. The surface quality the workpiece depends on properties these dies, where roughness, material hardness, wear evolution thei...
در این تحقیق فرآیند پرداختکاری فولاد گرم کار aisi h13 به روش جریان ساینده (aff) مورد مطالعه قرار گرفته و تاثیر پارامترهای مختلف پروسه از قبیل فشار اکستروژن، غلظت ذرات ساینده، اندازه ذرات ساینده و وضعیت اولیه سطح بر روی میزان کاهش زبری سطح و میزان برداشت ماده مورد بررسی قرار گرفت. نتایج این تحقیق نشان می دهد که افزایش غلظت ذرات ساینده باعث افزایش میزان کاهش زبری سطح و میزان برداشت ماده می شود. ا...
Our understanding of the global ecology of avian influenza A viruses (AIVs) is impeded by historically low levels of viral surveillance in Latin America. Through sampling and whole-genome sequencing of 31 AIVs from wild birds in Peru, we identified 10 HA subtypes (H1-H4, H6-H7, H10-H13) and 8 NA subtypes (N1-N3, N5-N9). The majority of Peruvian AIVs were closely related to AIVs found in North A...
Maternally and paternally derived alleles can utilize different promoters, but allele-specific differences in cotranscriptional processes have not been reported. We show that alternative polyadenylation sites at a novel murine imprinted gene (H13) are utilized in an allele-specific manner. A differentially methylated CpG island separates polyA sites utilized on maternal and paternal alleles, an...
