This study compared ankle range of motion (AROM) including dorsiflexion, plantar flexion, inversion and eversion, and venous refill time (VRT) in leg skin inflamed by venous disorders, before and after a new cryotherapy ulcer prevention treatment. Fifty-seven individuals participated in the randomized clinical trial;28 in the experimental group and 29 received usual care only. Results revealed no statistically significant differences between the experimental and usual care groups although AROM measures in the experimental group showed a consistent, non-clinically relevant decrease compared to the usual care group except for dorsiflexion. Within treatment group comparisons of VRT results showed a statistically significant increase in both dorsiflexion and plantar flexion for patients with severe VRT in the experimental group (6.9 ± 6.8;p = 0.002 and 5.8 ± 12.6;p = 0.02, respectively). Cryotherapy did not further restrict already compromised AROM, and in some cases, there were minor improvements.

The effects of a cyanobacterial extract （CE） on Helicobacter pylori biofilm formation onto hydrophobic and hydrophilic abiotic surfaces and the expression of luxS, flaA, omp18, lpxD and ureA genes associated to biofilm were studied. NCTC11638 reference strain and HP796, a resistant clinical isolate, were grown in Mueller-Hinton broth supplemented with 5% fetal calf serum （FCS） or 1% CE. The ability to form biofilm, viability, morphological changes and gene expression of adhered H. pylori cells were determined. The strains were able to form biofilm on both surfaces with the nutritional supplements analyzed. H. pylori conserved a characteristic bacillary morphology and viability with CE. Cells attachment was higher with CE than FCS regardless of strains and surfaces. The most remarkable increase in gene expression was observed with the ompl8 gene using the CE supplement, indicating the important participation of outer membrane proteins in biofilm establishment. The clinical isolate showed similar and even greater gene expression than the reference strain. The results obtained indicated that the nutrients provided by CE favored biofilm formation with retained pathogenicity that under certain conditions can occur in natural aquatic environments.

In this work, a grape phenolic extract obtained by methanol extraction has been demonstrated to be effective in inhibiting the growth of different strains and species of Campylobacter, one of the most important bacterial foodborne pathogens causing gastroenteritis worldwide. Noteworthily, it was particularly effective against several strains presenting multiple antibiotic resistances. In all cases, the minimum inhibitory concentration (MIC) was lower than 300 mg GAE/L, being of 60 mg GAE/L for one of the most resistant strains (C. coli LP2), while the others were between 120 mg GAE/L and 180 mg GAE/L. The analytical study of the main phenolic compounds in the grape extract revealed that it was mainly constituted by catechins (85.7%) and phenolic acids (13.7%). However, experiments developed using pure standards demonstrate that phenolic acids (such as gallic, p-hidroxibenzoic, vanillic, and homovanillic acids) were the most active, provoking a Campylobacter growth decrease between 6.7 and 7.6 log, while epicatechin was the only catechin with activity as pure compound (1 log of growth decrease).

Over the last decade, remote sensing technologies have provided useful tools for a diverse range of sectors. G-STEP （GMES--space technology exchange partnership） is the University of Leicester＇s flagship project for innovation, training and education in GMES （global monitoring for environment and security） and GIS （geographical information systems） based technologies. G-STEP （part funded by the ERDF） is the first GMES accelerator initiative in the UK and is breaking new ground in the application of GMES and GIS. The core G-STEP team initiates and develops Knowledge Exchange Practices between the University and Life Long Learning partners in the East Midlands Region, through training packages and collaborative research projects. The programme integrates innovative research, to direct downstream applied training, supported by analytical processing of attendee assessment data. Collated information derived from these sources presents a unique opportunity to incorporate a statistically viable feedback cycle, making G-STEP the interface between pure and applied research, thus initiating downstream dissemination to groups and small business. In this paper, we outline the GMES and GIS training packages, and the route to market to increase uptake of underused data streams via university and regional entrepreneurs （start-ups） and established small business with a core interest in utilisation and dissemination of novel technologies in sustainable lifelong learning.
