Abstract
The aetiology of essential hypertension is complex and involves both environmental and genetic factors. Approximately 30% of the inter-individual variability in blood pressure is genetically determined. It has been shown that numerous vasoconstrictors stimulate RhoA in local populations of vascular SMCs that, in turn, promote localised constriction of arterial blood vessels and elevations in blood pressure. The VAV3 gene encodes for VAV3 protein, a Rho GEF factor. VAV3-AS1 gene, a lncRNA, may regulate VAV3 expression. We performed an observational prospective case-control study, including patients attending in the Vascular Risk Unit from the University Hospital Salamanca for 6 months. A replication study was performed with data from The Kaiser Permanent database of the University of California. The results suggest that T allele of the VAV3 rs7528153 and G allele of the VAV3-AS1 rs11185222 polymorphisms are associated with an increased risk of developing hypertension. We hypothesise that these polymorphisms could modify blood pressure, likely through a modification in the Rho/Rac pathway. Our results suggest that those polymorphisms could be useful genetic markers of susceptibility to suffering hypertension.

Abstract
Neisseria gonorrhoeae is one of the most prevalent sexually transmitted diseases worldwide with more than 100 million new infections per year. A lack of intense research over the last decades and increasing resistances to the recommended antibiotics call for a better understanding of gonococcal infection, fast diagnostics and therapeutic measures against N. gonorrhoeae. Therefore, the aim of this work was to identify novel immunogenic proteins as a first step to advance those unresolved problems. For the identification of immunogenic proteins, pHORF oligopeptide phage display libraries of the entire N. gonorrhoeae genome were constructed. Several immunogenic oligopeptides were identified using polyclonal rabbit antibodies against N. gonorrhoeae. Corresponding full-length proteins of the identified oligopeptides were expressed and their immunogenic character was verified by ELISA. The immunogenic character of six proteins was identified for the first time. Additional 13 proteins were verified as immunogenic proteins in N. gonorrhoeae.
