Renin is the first limiting step of the RAAS and its role as a biomarker to improve CV risk stratification still remains a topic of debate. Several studies have shown that elevated plasma FK228 in vitro renin activity is associated with increased morbidity and mortality in patients with CV disease. The aim of this paper is to critically evaluate the evidence on the role of renin as a biomarker of CV risk and prognosis. With the new advances of pharmacological treatment acting on the RAAS, the effect of elevated levels of renin on the prognosis of these patients becomes even

more intriguing. (c) 2011 Elsevier B.V. All rights reserved.”
“Bovine leukocyte antigen DRB3 alleles from Holstein x Zebu crossbred dairy cows (n = 409) were analyzed using the PCR-RFLP technique. Exon II of DRB3 was amplified using locus-specific primers (HLO30/HLO32), followed by digestion with 3 restriction CUDC-907 mw enzymes (RsaI, BstyI, and HaeIII). Forty alleles were found with frequency

ranging from 0.005 to 0.139. The most frequently detected alleles of Holstein x Zebu were DRB3*16, *51, *23, *11, *8, and *1, accounting for 61.12% of the alleles in the population. Detection of candidate alleles for clinical mastitis occurrence was performed by logistic regression. It was found that percentage of Holstein fraction in crossbred cows had a nonsignificant effect (P > 0.05). However, parity had a significant effect on mastitis occurrence. In addition, DRB3*1 and *52 were the most associated with the occurrence of clinical mastitis, whereas

*15, *51, and *22 were associated with resistance in crossbred populations. This is the first report of association of DRB3*15 and *51 with mastitis resistance. The association was validated by examining the candidate alleles in GSK1838705A another commercial population. Highly susceptible (n = 43) and resistant (n = 42) groups of Holstein x Zebu cows were investigated. The result confirmed that DRB3*1 and *52 could be considered as susceptibility alleles, whereas *15, *51, and *22 could be considered as resistant alleles in Holstein x Zebu raised under tropical conditions. In addition, allele effects on 305-d milk production were estimated by BLUP. It was shown that most alleles associated with high clinical mastitis occurrence were related to increased milk yield. This study revealed that allele DRB3*10 had the greatest effect on increasing milk yield with moderate resistance to clinical mastitis, which could be used as a potential marker for selection in dairy genetic evaluation.”
“Kala-azar or visceral leishmaniasis is a disseminated protozoal infection caused by parasites of the genus Leishmania (Leishmania donovani in India). Conventional therapy for visceral leishmaniasis continues to be pentavalent antimony (sodium antimony gluconate [SAG]). Amphotericin B is widely used for SAG-unresponsive cases and sometimes even as a first-line drug, especially in endemic areas.
