To investigate the genetic variation in Haemophilus parasuis (HPS) in Sichuan, China, 11 isolates were analyzed based on the outer membrane protein P2 (OMPP2) sequence. Sequence analysis showed that the 11 isolates shared 93.0% to 100% nucleotide homology with 15 reference strains, and the consistency between the 26 strains was 89.0%. The isolates of HPS-1, 2, 4, 5, 6, 7, 8, 10 and 11 had a 69-base deletion from 770 base pairs (bp) to 850 bp, which was infrequent in China. The phylogenetic tree showed that HPS-3 and HPS-8 had closer relationships with European and Japanese strains, but shared 98...

Tyrosine receptor kinase B (TrkB), a receptor for brain-derived neurotrophic factor and neurotrophin-3, includes the alternatively spliced three isoforms specifically in rats. Each isoform, full length TrkB (TrkB FL), truncated TrkB type-1 (TrkB T1) and type-2 (TrkB T2), seems to mediate diverse cellular function. Some studies suggest that TrkB plays a key role in both neural and non-neural systems. In the present study, we examined mRNA and protein expression profile of three TrkB isoforms in normal adult rat multiple tissues...

First-generation cephalosporins such as cefazolin (CEZ) have been widely used for mastitis treatment in dairy cattle. However, the use of antibiotics results in the presence of antibiotic residues in milk, which is used for human consumption. Nisin A, a bacteriocin produced by Lactococcus lactis, has been used as a broad-spectrum food preservative for over 50 years. Therefore, a combination of CEZ and nisin A might provide an extended activity spectrum against mastitis pathogens and reduce the antibiotic dose for mastitis treatment...

During the autumn migration of many waterfowls, body mass is lowest upon arrival at the wintering area and gradually increases during the winter. Consequently, body mass is highest before the spring migration. We studied the pattern of body mass changes in the Black-Headed Gull (Larus ridibundus) from December 2010 to December 2016 in the Shinhama area of Chiba, Japan. Based on 327 captured animals, body mass increased during the wintering period, but tended to decrease before migration. In 2014-2016, a muscle mass reduction in females was observed, explaining the change in body mass...

The bovine MHC (BoLA) class II DRB3 alleles are associated with polyclonal expansion of lymphocytes caused by bovine leukemia virus (BLV) infection in cattle. To examine whether the DRB3*0902 allele, one of the resistance-associated alleles, is associated with the proviral load, we measured BLV proviral load of BLV-infected cattle and clarified their DRB3 alleles. Fifty-seven animals with DRB3*0902 were identified out of 835 BLV-infected cattle and had significantly lower proviral load (P<0.000001) compared with the rest of the infected animals, in both Japanese Black and Holstein cattle...

Cisplatin (CDDP) is a chemotherapeutic agent that is widely used in the treatment of lymphomas and solid malignancies. However, its clinical usage is limited by its severe side effects in the kidneys. Glomerular and tubular injuries in the kidneys commonly progress to interstitial fibrosis and, ultimately, the end stage of renal failure. We previously reported that 3-acetyl-5-methyltetronic acid (AMT) had inhibitory effects on rat renal vitamin K1 2,3-epoxide reductase (VKOR) in vitro and also suppressed mesangial cell proliferation and, consequently, the formation of fibrosis via the vitamin K-dependent activation of the growth arrest-specific 6 (Gas6)/Axl pathway in anti-Thy-1 glomerulonephritis (Thy-1 GN) in rats...

This study aimed to investigate the neuropathogenesis of equine herpes virus 9 (EHV-9) by studying the effects of a single point mutation introduced in two different EHV-9 genes. The two EHV-9 mutants, 14R and 19R, were generated carrying a point mutation in two separate EHV-9 genes. These mutants, along with the wild-type EHV-9, were used to infect a hamster model. The EHV-9- and 19R-infected groups showed earlier and more severe clinical signs of infection than the 14R-infected group. The white blood cells (WBCs) count was significantly increased in both EHV-9- and 19R-infected groups compared to the 14R-infected group at the 4th day post infection (DPI)...
