Abstract
Increasing impacts of both fisheries and climate change have resulted in shifts in the structure and functioning of marine communities. One recurrent observation is the rise of cephalopods as fish recede. This is generally attributed to the removal of main predators and competitors by fishing, while mechanistic evidence is still lacking. In addition, climate change may influence cephalopods due to their high environmental sensitivity. We aim to unveil the effects of different anthropogenic and environmental drivers at different scales focusing on the cephalopod community of the Western Mediterranean Sea. We investigate several ecological indicators offering a wide range of information about their ecology, and statistically relating them with environmental, biotic and fisheries drivers. Our results highlight non-linear changes of indicators along with spatial differences in their responses. Overall, the environment drivers have greater effects than biotic and local human impacts with contrasting effects of temperature across the geographic gradient. We conclude that cephalopods may be impacted by climate change in the future while not necessary through positive warming influence, which should make us cautious when referring to them as generalized winners of current changes.

Abstract
The bamboo-coral Isidella elongata is a key habitat-forming species in the deep Mediterranean Sea. This alcyonacean is listed as an indicator of Vulnerable Marine Ecosystems (VMEs) and as Critically Endangered due to bottom trawling impacts. In this work, a modeling approach was used to predict and map the habitat suitability of I. elongata in the Mediterranean Sea under current environmental conditions. Occurrence data were modeled as a function of environmental parameters. Using climate change scenarios and fishing effort data, the risk of climate change and fisheries impacts on habitat suitability were estimated, and climate refugia were identified. A drastic loss of habitat is predicted, and climate change scenarios suggest a loss of 60% of suitable habitats by 2100. In the central Mediterranean, climate refugia overlapped with active fishing grounds. This study represents the first attempt to identify hot spots for the protection of soft bottom Vulnerable Marine Ecosystems for the entire Mediterranean Sea, and highlights areas most at risk from trawling. This work is relevant to the objectives of the EU Marine Strategy Framework and Maritime Spatial Planning Directives, the Biodiversity Strategy for 2030 regarding priority areas for conservation.

Abstract
Macrovipera lebetina obtusa (MLO) is a venomous snake endemic to Middle East. Here we describe the therapeutic potential of the MLO snake venom. In S-180 sarcoma-bearing mouse model, we showed that the MLO snake venom inhibits tumour growth by 50%. In human dermal microvascular endothelial cells (HMVEC-D), treatment with the MLO snake venom lead to an increase of expression levels of the vascular endothelial growth factor (VEGF), while the level of the expression of caspase 8 did not change. In HMVEC-D cells MLO snake venom induces necroptosis, rather than apoptosis. In the chick embryo chorioallantoic membrane (CAM) assay, exposure to MLO snake venom inhibited bFGF-induced angiogenesis by 22%. Taken together, these results indicate that the MLO snake venom has a potent cytotoxic activity. Regulated necroptic cell death pathway, which is engaged by MLO snake venom, may become a promising novel target for antitumor therapies.

Abstract
The deep sea plays a critical role in global climate regulation through uptake and storage of heat and carbon dioxide. However, this regulating service causes warming, acidification and deoxygenation of deep waters, leading to decreased food availability at the seafloor. These changes and their projections are likely to affect productivity, biodiversity and distributions of deep-sea fauna, thereby compromising key ecosystem services. Understanding how climate change can lead to shifts in deep-sea species distributions is critically important in developing management measures. We used environmental niche modelling along with the best available species occurrence data and environmental parameters to model habitat suitability for key cold-water coral and commercially important deep-sea fish species under present-day (1951-2000) environmental conditions and to project changes under severe, high emissions future (2081-2100) climate projections (RCP8.5 scenario) for the North Atlantic Ocean. Our models projected a decrease of 28%-100% in suitable habitat for cold-water corals and a shift in suitable habitat for deep-sea fishes of 2.0°-9.9° towards higher latitudes. The largest reductions in suitable habitat were projected for the scleractinian coral Lophelia pertusa and the octocoral Paragorgia arborea, with declines of at least 79% and 99% respectively. We projected the expansion of suitable habitat by 2100 only for the fishes Helicolenus dactylopterus and Sebastes mentella (20%-30%), mostly through northern latitudinal range expansion. Our results projected limited climate refugia locations in the North Atlantic by 2100 for scleractinian corals (30%-42% of present-day suitable habitat), even smaller refugia locations for the octocorals Acanella arbuscula and Acanthogorgia armata (6%-14%), and almost no refugia for P. arborea. Our results emphasize the need to understand how anticipated climate change will affect the distribution of deep-sea species including commercially important fishes and foundation species, and highlight the importance of identifying and preserving climate refugia for a range of area-based planning and management tools.

Abstract
<p>La eficacia y tolerancia de levofloxacina (Floxaday®, Holliday-Scott) para el tratamiento de infecciones dérmicas y de vías urinarias, fue evaluada en caninos. Se incluyeron 26 casos clínicos que fueron tratados con 10 mg/kg vía oral cada 24 horas durante 14 y hasta 21 días. De los 14 casos de afecciones a nivel dérmico, 4 fueron severos y los restantes de severidad intermedia. De los 12 casos de infecciones a nivel urinario, 8 fueron procesos severos, 3 intermedios y uno bajo. La eficacia de los tratamientos fue evaluada aplicando una escala ad-hoc. El tratamiento fue exitoso en el 99% de los casos, observándose curación clínica al día 4 en el 6,25% y al día 7 en el 43,75%. En el día 14 la curación clínica fue registrada en el 99% de los pacientes; solamente uno de ellos requirió un tratamiento de 21 días para alcanzarla. En la población con infecciones urinarias todos los pacientes respondieron satisfactoriamente al tratamiento (curación clínica), el 42% lo hizo hacia el día 4 y el 83% al día 7. Al día 14, la curación clínica fue constatada en el 100% de los casos. No se observaron efectos secundarios en ninguno de los pacientes incluidos en el estudio. En caninos, levofloxacina administrada por vía oral a la dosis de 10 mg/kg una vez al día, demostró una excelente eficacia y nula aparición de efectos adversos.</p><p> </p>

Abstract
Lipid-based nanosystems, such as nanostructured lipid carriers (NLC) and nanoemulsions (NE) have been described as promising alternatives to conventional formulations for increase skin hydration. Besides, these systems have been used as efficient vehicles for lipophilic molecules that improve skin properties (e.g. vitamin E). In this study, we performed comparative investigations between hydrogels formulations containing vitamin E-loaded NLC (HG-NLCVE) and vitamin E-loaded nanoemulsion (HG-NEVE). The experiments started with particle size measurements, which showed no significant differences between nanoparticles/nanodroplets sizes after incorporation in the hydrogel net (386 nm vs. 397 nm for HG-NLCVE and 402 nm vs. 514 nm for HG-NEVE). Afterwards, in vitro biocompatibility studies in human keratinocytes were carried out, being observed that the lipid-based nanosystems were more cytotoxic for the cells before incorporation in the hydrogel. Finally, the formulations hydration potential and sensory attributes for skin application were evaluated by in vitro occlusion tests and in vivo human experiments. The results showed that the HG-NLCVE exhibited the best occlusive properties, whereas the HG-NEVE performed a faster skin hydration effect. Furthermore, the latter was selected as the most attractive for skin application, although the HG-NLCVE was described as more suitable to obtain a long-lasting effect. This study demonstrated the in vitro and in vivo safety and hydration potential of hydrogels containing vitamin E-loaded lipid-based nanosystems. These results establish a basis to assess the cutaneous use of these systems, despite more in vivo experiments, for longer periods and in more volunteers, are required before commercialization.

Abstract
The increase of anthropogenic pressures on the marine environment together with the necessity of a sustainable management of marine living resources have underlined the need to map and model coastal environments, particularly for the purposes of spatial planning and for the implementation of integrated ecosystem-based management approach. The present study compares outputs of a process-driven benthic habitat sensitivity (PDS) model to the structure, composition and distribution of benthic invertebrates in the Eastern English Channel and southern part of the North Sea. Trawl disturbance indicators (TDI) computed from species biological traits and benthic community composition were produced from samples collected with a bottom trawl. The TDI was found to be highly correlated to the PDS further validating the latter's purpose to identify natural process-driven pattern of sensitivity. PDS was found to reflect an environmental potential that may no longer be fully observable in the field and difference with in situ biological observations could be partially explained by the spatial distribution of fishery pressure on the seafloor. The management implication of these findings are discussed and we suggest that, used in conjunction with TDI approaches, PDS may help monitor management effort by evaluating the difference between the current state and the presumed optimal environmental status of marine benthic habitats.

Abstract
Truss analysis and length measurements were made on 168 striped red mullet Mullus surmuletus. Multivariate statistical analyses with principal component analysis and partial redundancy analysis (pRDA) were used on these measurements to evaluate the influence of maturity, sex and geographical area distribution on body shape. Truss measurements were important to quantify and discriminate changing body shape, presumably due to changing environmental conditions. Sexual dimorphism was not observed and juveniles could be distinguished from adults based on their body shape. More importantly, M. surmuletus occurring in different geographical areas could be differentiated using this method. Based on pRDA, a significant difference of head morphological dimensions was observed between populations occurring in the eastern English Channel and those occurring in the Bay of Biscay, suggesting that fish from these areas could represent two subpopulations.

Abstract
OBJECTIVE To find correlations between radiological coracoacromial arch geometry and shoulder function in patients with subacromial impingement syndrome. PATIENTS AND METHODS During a prospective study of the efficacy of arthroscopic subacromial decompression, we evaluated the function of the treated and contralateral shoulders using Constant's functional score and confronted the results to several radiographic parameters reflecting coracoacromial arch geometry. RESULTS Constant's score values were low (42 +/- 15) because of pain and a low level of activity. Males had significantly higher scores than females. Constant's score was unaffected (P > 0.05) by patient age, the side, the level of activity, or the duration of symptoms, but was significantly influenced by the orientation of the acromion with respect to the scapular spine and to the vertical scapular axis. The preoperative Constant's score was significantly higher in patients with a more horizontal acromion (P = 0.01). A very tight correlation was found between the preoperative Constant's score and the angle between the acromion and scapular spine (P = 0.0003). CONCLUSION Based on our results, we defined an open and a closed coracoacromial arch geometry. Coracoacromial arch geometry is correlated with shoulder function syndrome and can assist in the interpretation of rotator cuff impingement.

Abstract
The authors report a case of peri-lunar luxation of the carpus, associated with a Bennett's fracture, a fracture of the second metacarpal and with an avulsion of the radial styloid. Even if, each injury alone is commonplace, we did not find this combination, in the literature. It reiterates the importance of not ignoring, on X-rays, one of the four wounds, and the problem of the surgical strategy, for the treatment of all of the injuries at a time. Peri-lunar dislocation of the carpus is quite an unusual injury, affecting mainly young men. In one third of cases, the peri-lunar dislocation is unnoticed at first examination. This problem is even more acute when associated wounds, which are evident on X-rays, exist. The operative technique, used in the treatment of such wounds, depends on the severity. For peri-lunar luxation on the small curve, closed reduction is used. For one on the large curve, it is better to use open reduction, as for, most probably, for associated lesions, operated on late.

Abstract
Serum levels of total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C) and triglycerides (TG) were determined on 239 school children aged 5-19 years belonging to lower middle class families. The mean TC, LDL-C, HDL-C and TG ranged from 3.70-4.37 mmol/L, 2.17-2.70 mmol/L, 0.94-1.14 mmol/L, 1.07-1.26 mmol/L respectively. In general, girls had higher TC, LDL-C and HDL-C levels. There was no significant difference in the TG levels between boys and girls. Thirty-three percent of the girls and 22% of the boys had TC level > or = 4.4 mmol/L, the level at which dietary intervention is recommended for children. Fifty-three percent of the girls and 37% of the boys had TG levels > or = than the 90th percentile of the levels for children of similar age and sex in North America. The HDL-C levels were low with 37% of the girls and 44% of boys having values < or = the 10th percentile of levels for North American children. The mean daily intake of cholesterol ranged from 241 mg to 364 mg/day. Except for the 5-9 year olds, boys had a higher cholesterol intake than girls (P < 0.005). Twenty-two percent of the boys and 32% of the girls were overweight but weight status was significantly associated with elevated TC levels only in the boys (P < 0.05). Activity level was not significantly related to TC levels but girls who were active had significantly higher HDL-C levels than girls who were sedentary (P < 0.02).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Eighty-eight school children and their parents who had been counselled regarding appropriate dietary and activity patterns aimed at reducing serum cholesterol were followed-up 21 months later to determine changes in dietary and activity patterns and in serum lipid levels. The decline in serum total cholesterol ranged from 8 to 14% in the different age and sex groups (P < 0.05 to P < 0.001). Serum triglycerides did not change significantly. Cholesterol intake decreased 36% and 54% in 10-14 year old boys and girls respectively (P > 0.001). The activity level increased significantly in both the 5-9 year and 10-14 year olds (P < 0.05 to P < 0.005). These results show that nutrition education can bring about a change in dietary and activity patterns, resulting in a decline in serum cholesterol levels.
