Abstract
Pasteurella multocida belongs to the normal flora of the respiratory and digestive tract of many animals. Animal exposure is a considerable risk factor for Pasteurella infection. P. multocida is the most common cause of local infection after an animal bite but is an unusual cause of meningitis. We present a case of bacterial meningitis by P. multocida in a 37-year-old man who worked in a pig farm and was bitten by a pig. The patient had a defect located in the lamina cribosa and this lesion could be the gateway of the infection, although in this case the infection could also be acquired through the pig bite. The bacteria was identified as P. multocida with the biochemical test API 20E (bioMérieux). In agreement with findings in the literature, the strain was susceptible in vitro to penicillin, ampicillin, cefotaxime, ceftriaxone ciprofloxacin, levofloxacin, imipenem and tetracycline.

Abstract
Muscular samples from the oesophagus, diaphragm and heart of 101 roe deer (Capreolus capreolus) hunted in Galicia (Northwestern Spain) were examined, by the compression method, for the presence of Sarcocystis spp. infection. The structure of the cyst wall was examined by light (LM) and transmission electron microscopy (TEM). The overall prevalence of infection was very high (99%), with a density of 404 cysts/sample (SD 812). The prevalence was very similar in the different examined muscle types (99% heart and diaphragm, and 98.9% oesophagus). A significantly higher intensity of infection was found in the heart (831; SD 1281), followed by the diaphragm (197; SD 190) and the oesophagus (180; SD 205). Macrocysts (>1500 μm long) were only detected in the oesophagus of 48.5% of the examined roe deer; their mean size was 2055.4 μm (SD 632.46). Cysts localised in the myocardium were significantly shorter (371.5 μm; SD 160.47) than those found in the diaphragm (678.2; SD 546) and the oesophagus (973.4 μm; SD 667.87). By LM, most of the cysts (98.8%) displayed a thin wall, which was consistent with those of Sarcocystis sp., S. gracilis and S. capreolicanis; only 1.2% of the cysts had a thick striated wall, consistent with Sarcocystis silva. Three morphological distinct sarcocysts were observed by TEM: the unnamed species Sarcocystis sp., S. capreolicanis and S. gracilis. The wall ultrastructure of the examined macrocysts was consistent with S. gracilis. This study has revealed that Spanish roe deer harbours 4 morphologically distinct types of sarcocysts; being the first record of S. gracilis in roe deer from Spain.

Abstract
1H-indazoles are good candidates for studying the phenomena of molecular association and spontaneous resolution of chiral compounds. Thus, because the 1H-indazoles can crystallize as dimers, trimers, or catemers, depending on their structure and the phase that they are in, the difficulty in the experimental analysis of the structure of the family of 1H-indazoles becomes clear. This difficulty leads us to contemplate several questions: How can we determine the presence of different structures of a given molecular species if they change according to the phase? Could these different structures be present in the same phase simultaneously? How can they be determined? To shed light on these questions, we outline a very complete strategy by using various vibrational spectroscopic techniques that are sensitive (VCD) and insensitive (IR, FIR, and Raman) towards the chirality, together with quantum chemical calculations.

Abstract
We show a simple method to visualize the morphology of water adsorbed within the pore network of colloidal crystals made of submicrometer silica spheres. Water is replicated into silica by modified silicon tetrachloride hydrolysation under standard ambient conditions, making it visible to standard electronic microscopy and thus allowing one to discern the original water distribution. Different distribution patterns are identified depending on the water content, surface condition, and spheres arrangement. The dimension and shape of wetting layers (covering the submicrometer spheres) and capillary bridges (joining them) are measurable at the nanoscale. We finally use these findings to demonstrate proof-of-principle of fabrication of isolated and freestanding silica nanorings by using hydrophobic polymeric templates and selective etching.

Abstract
Intestinal contents of 218 roe deer hunted in the northwest (NW) of the Iberian Peninsula during the 2008-2009 hunting seasons were examined in order to provide information on the gastrointestinal (GI) nematode prevalence and intensity of infection and the possible influence of some environmental and intrinsic factors such as climatic conditions, age and sex. All the animals studied harboured GI nematodes, and a total of 20 different species belonging to ten genera were identified. Spiculopteragia spiculoptera/Spiculopteragia mathevossiani, Ostertagia leptospicularis/Ostertagia kolchida and Nematodirus filicollis were the most common. This is the first citation for Chabertia ovina, Cooperia pectinata, Cooperia punctata, Cooperia oncophora, Haemonchus contortus, Nematodirus spathiger, Oesophagostomum venulosum, Teladorsagia trifurcata, Trichostrongylus capricola, Trichostrongylus colubriformis, Trichostrongylus vitrinus and Trichuris capreoli in roe deer from the Iberian Peninsula. Prevalence and intensity were significantly higher in the abomasum, where infections with more than one GI nematode species were the most common; in the other intestinal segments infections with only one GI nematode species were the most prevalent. When considering the influence of the different risk factors on the prevalence of GI nematodes, the highest prevalence for most of the genera were observed in roe deer from coastal areas, where climatic conditions are more favourable for the development and survival of third stage larvae in the environment. Regarding the sex of the animals, the prevalence was, in general, higher in males than in females, probably due to behavioural and physiological sex-related differences. On the contrary, no differences were found in relation to the age of the animals. This study reveals that roe deer from the NW of the Iberian Peninsula are widely and intensely infected with gastrointestinal nematodes, which probably affect the health status of these ungulates.

Abstract
The aim of the present research was to determine the effect of low protein diets on growth performance, carcass traits and ammonia emission from barrows and gilts during the growing and finishing periods. For each period, three diets were formulated. A control diet (C) with 160 and 155 g crude protein (CP)/kg for the growing and finishing, respectively, a medium level diet (M) and a low level diet (L) with 10 and 20 g CP/kg less than the C, respectively. All the diets were supplemented with crystalline amino acids on an ideal protein basis. Barrows (90) and gilts (90) were sorted by bodyweight and sex and housed in three identical manually ventilated chambers. No significant effects of diet on pig performance were observed. In the finishing period, barrows were heavier (P < 0.001) and had higher average daily gain (P < 0.01) and average daily feed intake (P < 0.01) than gilts. Pigs fed the L diet had higher backfat thickness than those fed the other diets in the growing period (P < 0.05). Backfat thickness was higher (P < 0.01) in barrows than in gilts. Muscle depth decreased in pigs fed the L diet in the finishing period. Muscle depth was not affected (P > 0.05) by sex. Average ammonia emissions during the last 6 days were 117.7, 94.2 and 85.5 mg ammonia/kg pig.day for pigs fed the C, M and L diets, respectively. The results show that a reduction in dietary CP of 10 g/kg, accompanied by supplementation with crystalline amino acid reduced ammonia emission by 19.9% with no detrimental effects on growth performance and carcass characteristics, and a reduction of 20 g/kg reduced ammonia emission by 27.3% with no detrimental effects on growth performance but reduced muscle depth at slaughter.

Abstract
OBJECTIVE The aim of this study was to evaluate the contribution made by ultrasound-guided transversus abdominis plane block (TAP) to the quality of the analgesia with intrathecal opioids obtained in patients undergoing elective caesarean delivery. MATERIAL AND METHODS A prospective, randomized study in patients submitted to elective caesarean section with spinal anaesthesia with 0.5% hyperbaric bupivacaine. The patients were randomized into 3 groups according to the added complementary drug for analgesia: group A morphine 0.1mg; group B fentanyl 10 μg; group C 10 μg fentanyl+bilateral TAP block. The TAP block with 20 ml of 0.5% levobupivacaine on each side, after surgery. Groups A and B, were injected with 20 ml of saline. Postoperative analgesia was performed with morphine bolus through a system of patient-controlled analgesia (PCA). We studied the pain on a visual analogue scale at 12 and 24h at rest and movement, the time elapsed to require the first bolus, and morphine bolus in 24h. Secondary effects such as nausea, vomiting, pruritus, and drowsiness, were also evaluated. The level of patient satisfaction was also recorded. RESULTS A total of 90 patients were included. At rest the 12/24h VAS score was: group A, at 12h 2.1 ± 1.2, at 24h 4.7 ± 1.6; group B at 12h 4.3 ± 2.9, at 24h 4.8 ± 2; group C at 12h 1.9 ± 1.09, at 24h 2.3 ± 1.2 (P<.05). Walking improved analgesia more in group C (P ≤.02). The time of asking for the first bolus was lower in group B: group A 9.3 ± 4.9h (P=.02 compared to group C), in group B 2 ± 1.8h (P<.001 compared to group C) and group C 13.2 ± 2.1h. The number of bolus in 24h in group B was 38 ± 5, in group A 10 ± 2 (P<.05), group C 5 ± 2 (P<.001). Delayed nausea was increased in group B (36.6%) and pruritus was greater in group A (36.6%). CONCLUSIONS Ultrasound (US)-guided TAP block improves spinal opioid analgesia, with a decrease in VAS scores in the first 24h, and reduces opioid requirement and secondary effects after caesarean delivery.

Abstract
Transgenic Bt maize expressing the Cry1Ab toxin is poorly effective for suppressing populations of two non-target Lepidoptera, Mythimna unipuncta and Helicoverpa armigera. In order to determine the mechanisms that may be involved in this poor effectiveness, last instar larvae of the two Lepidoptera were fed with a diet containing lyophilized leaves with Bt vs non-Bt toxin for different periods; additionally, some larvae fed on Bt diet were transferred to non-Bt diet for an additional period. In the experimental larvae, we measured the growth (weight) gain from just before treatment to after the end of the treatment, and the Cry1Ab contents in the hemolymph, the peritrophic membrane and its contents and midgut epithelium. Effects of the treatments on the midgut epithelium were observed by light and transmission electron microscopy. It was seen that multiple mechanisms can be involved in the low susceptibility of the two Lepidoptera. The low content of the toxin within the peritrophic membrane 48 h after ingestion indicates a high rate of toxin elimination in this space. Moreover, M. unipuncta larvae fed on the Bt diet displayed a similar growth gain index to those fed on the non-Bt diet, and showed an increasing elimination rate during the experiment. Little toxin reached the midgut epithelium, indicating a low permeability of the peritrophic membrane or a low affinity at the binding sites. Larvae fed on the Bt toxin showed rapid recovery in weight gain and in the midgut epithelium, and also showed overcompensation mechanisms.

Abstract
UNLABELLED Yeasts occur as part of the normal human microbiota. Nevertheless, some species are opportunistic, affecting immunocompromised patients such as those undergoing oncologic treatment. OBJECTIVE To detect the presence of yeasts in patients suffering from head and neck cancer who are receiving radiation therapy and display lesions in the oral cavity, compatible with candidiasis; and to evaluate the antifungal susceptibility of the isolates recovered. METHODS Sixty samples from patients were obtained by swabbing the oral mucosa. Identification of isolates were performed by classical taxonomic, morphological and biochemical methods as well as by using commercial identification kits. Susceptibility to antifungal drugs was determined by the agar diffusion method with Neosensitabs(®) disks. RESULTS Forty-six samples (77%) yielded positive findings, and species recovered were: Candida albicans (22 isolates), Candida tropicalis (13 isolates), Candida parapsilosis (six strains), Candida krusei (three strains), Candida dubliniensis and Saccharomyces cerevisiae (one each). All strains were susceptible to itraconazole, clotrimazole, voriconazole, nystatin and amphotericin B. On the other hand, 65% of strains were miconazole-susceptible while 35%, showed intermediate susceptibility. With regard to ketoconazole, only three strains (7%) corresponding to C. albicans (one isolate) and C. krusei (two isolates) displayed intermediate susceptibility. Only C. krusei strains were resistant to fluconazole while all the other species were susceptible. Eventually, only six isolates (13%) were susceptible to terbinafine while the remaining strains were resistant in vitro. CONCLUSION Early detection of etiological agents causing lesions, as well as the evaluation of their susceptibility to commonly used drugs, are crucial in order to choose the appropriate treatment that will minimize complications while improving the quality of patients' lives.

Basophilic intracellular prokaryotic-like colonies were observed in the gills of banded carpet shell Polititapes virgineus (= Tapes rhomboides) (Linnaeus, 1767) from a natural bed in Galicia (NW Spain). Light microscope observations suggested the presence of 2 types of colonies, but transmission electron microscopy revealed that these were the same Rickettsiales-like colonies, one infected and the other uninfected by phage particles. This is the first report of the presence of phage particles in Rickettsiales-like organisms in the gills of P. virgineus.

Abstract
Justificación: la movilidad en la comunidad es esencial en la vida de toda persona. El uso de transporte es una actividad instrumental que posibilita la movilidad en la comunidad. En la vejez esta actividad puede presentar características asociables al envejecimiento individual, la actividad misma, y el ambiente. Emerge la relevancia de conocer esta ocupación en las personas mayores chilenas y su implicancia para la Terapia Ocupacional como disciplina promotora de participación y autonomía en la vejez. Objetivo: se buscó explorar características del desempeño de un grupo de personas mayores en el uso transporte en Santiago a partir de sus experiencias y percepciones. Metodología: Se realizó diez entrevistas a adultos mayores que luego fueron analizadas con un enfoque interpretativo – hermenéutico. Resultados: Cinco temas principales emergieron del análisis de entrevistas: “función del uso del transporte público”, “adaptaciones preparatorias para un mejor desempeño”, “influencia del ambiente”, “¿bus o metro? razones para la elección” y “significado del uso: autonomía versus exclusión”. Conclusiones: En el grupo participante el uso del transporte se veía limitado por el ambiente físico, y facilitado por el ambiente social, y las personas desplegaban estrategias adaptativas para un mejor desempeño. El significado del uso de transporte se relacionó con la mantención de la autonomía y la identidad. El sistema de transporte en Santiago puede no ajustarse a las necesidades de la población mayor y puede percibirse como un elemento de exclusión social para las personas mayores.
