In this study, rotavirus CC0812-1 was purified from the culture supernatant of CC0812-1-infected MA104 cells and used as antigen to immunize BALB/c mice. Four hybridoma clones were developed secreting antibodies that reacted with CC0812-1, designated as 1B1, 1B8, 1F11, and 1G10, respectively. Western blot analysis indicated that the four monoclonal antibodies (MAbs) were all specific for VP4 of rotavirus CC0812-1. Isotyping revealed that MAbs 1B1, 1B8, and 1G10 belonged to the IgM class, while MAb 1F11 belonged to the IgG1 subclass. A neutralization test demonstrated that the four MAbs all had the capacity to neutralize rotavirus this website CC0812-1. The neutralizing

titers of the BALB/c mice ascites were 1:2048, 1:1024, 1:512, and 1:512 for MAbs 1B1, 1B8, 1F11, and 1G10, respectively.”
“Objective: To examine effects of high omega-3 (n-3) polyunsaturated fatty acid (PUFA) diets on development of osteoarthritis (OA) in a spontaneous guinea pig model, and to further characterise pathogenesis in this model. Modern diets low in n-3 PUFAs have been linked with increases in inflammatory disorders, possibly including OA. However,

n-3 is also thought to increases bone density, which is a possible contributing factor in OA. Therefore we aim to determine the net influence of n-3 in disease development.

Method: OA-prone Dunkin-Hartley (DH) Guinea pigs were compared with OA-resistant Bristol Strain-2s (BS2) each fed a standard or learn more an n-3 diet from 10 to 30 weeks (10/group). We examined cartilage and subchondral bone pathology by histology, and biochemistry, including collagen cross-links, matrix metalloproteinases (MMPs), alkaline phosphatase, glycosaminoglycan (GAG), and denatured type II collagen.

Results:

Dietary n-3 reduced disease in OA-prone animals. Most cartilage parameters were modified by n-3 diet towards those seen in the non-pathological BS2 strain – significantly active MMP-2, lysyl-pyridinoline and total collagen cross-links – the only exception being pro MMP-9 which was lower in the BS2, yet increased with n-3. GAG content was BI 6727 in vitro higher and denatured type II lower in the n-3 group. Subchondral bone parameters in the DH n-3 group also changed towards those seen in the non-pathological strain, significantly calcium:phosphate ratios and epiphyseal bone density.

Conclusion: Dietary n-3 PUFA reduced OA in the prone strain, and most disease markers were modified towards those of the non-OA strain, though not all significantly so. Omega-3 did not increase markers of pathology in either strain. (C) 2011 Osteoarthritis Research Society International. Published by Elsevier Ltd. All rights reserved.”
