Abstract
The widespread use of wipes and other sanitary products made of nonwoven fibres has led to an enormous problem in wastewater treatment systems that has been underestimated for some time. To date, there are no practical alternatives for recycling and valorisation. In this study, cellulosic rejections recovered from a wastewater treatment plant in Barcelona (Spain) were characterised and treated using hydrothermal and enzymatic methods to obtain free sugars. Steam explosion and autoclave pre-treatments were performed at different temperatures (120, 130, or 150 °C) and residence times (10-40 min) under neutral, acidic or basic conditions. The solids obtained after the pre-treatment, as well as the untreated material, were subjected to enzymatic hydrolysis using commercial enzymes. The untreated substrate reached the highest sugar production: 29 g glucose and xylose per 100 g of the cellulosic rejections, equivalent to 86% of the sugars contained in the initial material. These sugars can subsequently be transformed into biofuels or bioproducts within a biorefinery approach.

Abstract
Abstract
Background
In the current “obesity epidemic”, obese individuals without insulin resistance, lipid disorders, or hypertension, have been called “metabolically healthy” (MHO) and considered to have intermediate cardiovascular risk, between that of healthy nonobese (HNO) individuals and of metabolically unhealthy obese (MUO). Nonetheless, this is controversial, as MHO may have subclinical abnormalities, and indeed may be a transitory state in the way to the unhealthy phenotype.
Purpose
To evaluate systemic microvascular reactivity in MHO, MUO and HNO.
Methods
Ten MHO, 10 MUO and 20 HNO individuals were studied. Obesity was considered as a BMI ≥30 kg/m2. The NCEP/ATPIII criteria, excluding waist circumference, were used to define the metabolically healthy phenotype (absence of all criteria) or unhealthy phenotype (presence of any of the criteria). Laser speckle contrast imaging coupled with skin acetylcholine (Ach) iontophoresis was employed to study cutaneous microvascular reactivity (endothelial-dependent vasodilatation), as a surrogate for systemic microvascular function, and cutaneous vascular conductance [CVC in arbitrary perfusion units of microvascular flow (APU)/mean arterial pressure (mmHg)] was measured.
Results
Mean age was 34.8, 36.7 and 32.3 years (P=0.17, ANOVA) and BMI was 20.7, 32.2 and 33.3 kg/m2 (P<0.0001) for HNO, MHO and MUO, respectively. Both MHO and MUO had significantly decreased microvascular vasodilation in comparison to HNO (Figure 1). Of note, there was no significant difference between MHO and MUO regarding CVC (both similarly decreased when compared to the healthy controls).
Conclusions
This study underscores that MHO is not a “benign” condition, as it has adverse effects on microvascular function, similarly to those found in MUO. The study of cutaneous microvascular function may be useful to identify subclinical abnormalities in obese individuals who might deserve more intensive management.

Abstract
Evolutionary origins of novel forms are often obscure because early and transitional fossils tend to be rare, poorly preserved, or lack proper phylogenetic contexts. We describe a new, exceptionally preserved enigmatic crab from the mid-Cretaceous of Colombia and the United States, whose completeness illuminates the early disparity of the group and the origins of novel forms. Its large and unprotected compound eyes, small fusiform body, and leg-like mouthparts suggest larval trait retention into adulthood via heterochronic development (pedomorphosis), while its large oar-like legs represent the earliest known adaptations in crabs for active swimming. Our phylogenetic analyses, including representatives of all major lineages of fossil and extant crabs, challenge conventional views of their evolution by revealing multiple convergent losses of a typical "crab-like" body plan since the Early Cretaceous. These parallel morphological transformations may be associated with repeated invasions of novel environments, including the pelagic/necto-benthic zone in this pedomorphic chimera crab.

Abstract
Giardia lamblia, the aetiological agent of human giardiasis, is a frequently identified protozoan infection of the upper small intestine. It mainly affects children and has a wide range of clinical manifestations, from asymptomatic carriage to acute or chronic diarrhoea with dehydration, abdominal pain, nausea, vomiting, excessive flatulence and weight loss. Standard treatment for giardiasis is commonly with 5-nitroimidazole (5-NI) compounds, or nitazoxanide; however, some individuals experience treatment failure. For such patients, a combination of two or more drugs may be a viable approach. We report our experience with 11 paediatric patients with drug-refractory giardiasis, for whom therapy with a combination of secnidazole (SNZ) (30 mg/kg/day, divided into 2 doses, for 3 days) and albendazole (ABZ) (400 mg daily for 5 days) resulted in cure for 9 of the 11 (82%) patients. This combination of drugs was well tolerated; only mild, transient, and self-limited side effects were reported and these did not require discontinuation of treatment. These results support the use of SNZ plus ABZ as an alternative treatment for paediatric patients with giardiasis who have failed conventional treatments. Further research is needed to establish the safety of this combination and how it compares to other combination strategies.

Abstract
Background The validity of the surveys on self-reported smoking status is often questioned because smokers underestimate cigarette use and deny the habit. It has been suggested that self-report should be accompanied by cotinine test. This report evaluates the usefulness of serum cotinine test to assess the association between smoking and periodontal status in a study with a large sample population to be used in studies with other serum markers in epidemiologic and periodontal medicine researches. Material and Methods 578 patients who were part of a multicenter study on blood biomarkers were evaluated about smoking and its relation to periodontal disease. Severity of periodontal disease was determinate using clinical attachment loss (CAL). Smoking was assessed by a questionnaire and a blood sample drawn for serum cotinine determination. Results The optimal cut-off point for serum cotinine was 10 ng/ml. Serum cotinine showed greater association with severity of CAL than self-report for mild-moderate CAL [OR 2.03 (CI95% 1.16-3.53) vs. OR 1.08 (CI95% 0.62-1.87) ] advanced periodontitis [OR 2.36 (CI95% 1.30- 4.31) vs. OR 2.06 (CI95% 0.97-4.38) ] and extension of CAL > 3 mm [ OR 1.78 (CI95% 1.16-1.71) vs. 1.37 (CI95% 0.89-2.11)]. When the two tests were evaluated together were not shown to be better than serum cotinine test. Conclusions Self-reported smoking and serum cotinine test ≥ 10ng/ml are accurate, complementary and more reliable methods to assess the patient’s smoking status and could be used in studies evaluating serum samples in large population and multicenter studies.
Clinical Relevance: The serum cotinine level is more reliable to make associations with the patient’s periodontal status than self-report questionnaire and could be used in multicenter and periodontal medicine studies. Key words:Biological markers, serum, cotinine, periodontitis, smoking.

Abstract
OBJECTIVES The relationship between radiographic grayscale and elastic modulus was determined using mandibular cortical bone of colobine monkeys. Quantification of this relationship is critical for establishing absolute measures of structural rigidity of skeletal elements. MATERIALS AND METHODS We determined the Vickers microhardness values in mandibular bone from two species of African colobine monkeys and related these values to elastic modulus through an empirically determined correlation. We also determined radiographic grayscale values from microcomputed tomographic scans of the mandible in the same regions in which microhardness was sampled. We then correlated modulus to grayscale with a power law relationship. RESULTS We found that elastic modulus scaled with negative allometry with respect to grayscale with an exponent of 0.77. DISCUSSION Our results suggest a single exponent can effectively capture the relationship of grayscale to elastic modulus and facilitate development of heterogeneous structural models for use in comparative and computational biomechanical studies.

Abstract
A pretreatment that combines a thermo-mechanical process (extrusion) with chemical and biological catalysts to produce fermentable sugars from barley straw (BS) biomass was investigated. BS was firstly extruded with alkali and then, the pretreated material (extrudate) was submitted to extrusion with hydrolytic enzymes (bioextrusion). The bioextrudate was found to have 35% (w/w dwb) of total solids in soluble form, partly coming from carbohydrate hydrolysis during bioextrusion. About 48% of soluble solids dry weight is comprised by sugars, mostly glucose and xylose. Further enzymatic hydrolysis of bioextrudate could be successfully carried out at high solid loading level of 30% (w/v), with sugar production yield of 32 g glucose and 18 g xylose/100g bioextrudate at 72 h incubation (equivalent to 96 and 52 g/l concentration, respectively). These results, together with the high level of integration of the process, indicate a great potential of this pretreatment technology for sugar production from lignocellulosic substrates.

Abstract
Recent genetic studies have linked mental illness to alterations in disrupted in schizophrenia 1 (DISC1), a multifunctional scaffolding protein that regulates cyclic adenosine monophosphate (cAMP) signaling via interactions with phosphodiesterase 4 (PDE4). High levels of cAMP during stress exposure impair function of the prefrontal cortex (PFC), a region gravely afflicted in mental illness. As stress can aggravate mental illness, genetic insults to DISC1 may worsen symptoms by increasing cAMP levels. The current study examined whether viral knockdown (KD) of the Disc1 gene in rat PFC increases susceptibility to stress-induced PFC dysfunction. Rats were trained in a spatial working memory task before receiving infusions of (a) an active viral construct that knocked down Disc1 in PFC (DISC1 KD group), (b) a 'scrambled' construct that had no effect on Disc1 (Scrambled group), or (c) an active construct that reduced DISC1 expression dorsal to PFC (Anatomical Control group). Data were compared with an unoperated Control group. Cognitive performance was assessed following mild restraint stress that had no effect on normal animals. DISC1 KD rats were impaired by 1 h restraint stress, whereas Scrambled, Control, and Anatomical Control groups were unaffected. Thus, knocking down Disc1 in PFC reduced the threshold for stress-induced cognitive dysfunction, possibly through disinhibited cAMP signaling at neuronal network synapses. These findings may explain why patients with DISC1 mutations may be especially vulnerable to the effects of stress.

Abstract
OBJECTIVES Therapeutic hypothermia following cardiorespiratory arrest has been demonstrated to have cardio- and neuroprotective effects, resulting in improved survival and better neurological outcomes. The objective of this study was to assess the outcomes of patients undergoing therapeutic hypothermia following cardiorespiratory arrest. METHODS A prospective, 10-month observational study of patients admitted to an intensive care unit and undergoing therapeutic hypothermia after cardiorespiratory arrest was undertaken. Therapeutic hypothermia was induced by cold fluid administration and body surface cooling in patients admitted no more than 12 hours after resuscitation from cardiorespiratory arrest. A target temperature of 33ºC was maintained for 24 hours. RESULTS Overall, 12 patients were included (median age 64 years, 58% male). Half of the cardiorespiratory arrests were in-hospital. The median first-day Charlson Index, Sequential Organ Failure Assessment (SOFA) and Acute Physiology and Chronic Health Evaluation II scores were of 2.9, 11 and 24.5, respectively. The intensive care unit mortality rate was 42% (N=5). Five of the 7 surviving patients recovered their pre-cardiorespiratory arrest neurological status. Hypothermia was initiated 120 min (median) after recovery of spontaneous circulation. Most patients (75%) required vasopressor support. During the first 3 days after cardiorespiratory arrest and therapeutic hypothermia, a progressive SOFA score decrease (median 11 on day 0, 10 on day 1 and 7 on day 2) was observed. DISCUSSION In this study, therapeutic hypothermia was applied to all post-cardiorespiratory arrest patients and demonstrated good neurological outcome in surviving patients.

Abstract
IntroductionFibromyalgia seems to be associated with various forms of psychopathology, particularly major affective disorders.ObjectiveTo evaluate associated psychopathology in a series of women with diagnosis of fibromyalgia.MethodsPatient inclusion from 1st March to 30th June 2010. Symptom Checklist (SCL-90-R) was used for evaluation. SPSS was used for statistical analysis of data and results.ResultsA total of 34 women voluntarily joined our study. Mean age was 52.2 years (standard deviation (SD) 7.17). 11.4% were singled, 74.3% married or unmarried couples, 8.6% were divorced, and 5.7% were widowers. 74.3% of women lived with their couple and/or children whereas 8.6% lived by their own, and 8.6% with their parents. Results obtained with SCL-90-R showed:Global Severity Index (GSI) 1.86 (Standard Deviation (SD) 0.54); Positive Symptom Distress Index (PSDI) 2.58 (SD 0.36); Positive Symptom Total (PST) 167.85 (SD 49.30); Somatization (SOM) 2.62 (SD 0.53); Obsessive-Compulsive (O-C) 2.59 (SD 0.78); Interpersonal Sensitivity (I-S) 1.50 (SD 0.86); Depression (DEP) 2.5 (SD 0.75); Anxiety (ANX) 1.75 (SD 0.74); Hostility (HOS) 1.11 (SD 0.82); Phobic Anxiety (PHOB) 1.09 (SD 0.84); Paranoid Ideation (PAR) 1.11 (SD 0.85); Psychoticism (PSY) 1.05 (SD 0.62), and other vague symptoms 2.15 (SD 0.70).ConclusionOur patients with fibromyalgia scored higher in somatization, obsession-compulsion, depression, and anxiety. In view of the results, there is an important association between fibromyalgia and various forms of psychopathology.

Abstract
10670 Background: T combined with weekly H confers greater tumor response and survival compared to T monotherapy in P with Her-2 positive MBC. A recent report has demonstrated that H can be administered q3wks. The primary endpoint is to evaluate time to progression (TTP). Sencondary objectives are response rate, overall survival and safety profile. Methods: P cytologically or histologically confirmed of metastatic breast cancer, HER-2 positive (+++ by Herceptest, or FISH positive), age > 18, ECOG PS ≤ 2, and adequate organ function, were included. Prior chemotherapy for MBC or adjuvant anthracycline-based regimen in the previous 6 months was not allowed. Treatment: T 100 mg/m2 iv D1 q3wks for 6 cycles, H 8 mg/kg (cycle 1) and 6 mg/kg (consecutive cycles) iv D1, q3wks. P may receive H monotherapy until PD at the investigator criteria. Results: Over 41 analyzed P, median age was 57 years (29–75); ECOG PS 0–1 95% and ductal carcinoma 88%. Twenty five P received prior chemotherapy. Treatment: 217 cycles of TH (median 6) were administered. After that, 23 P received 189 cycles of H monotherapy (median 5, 1–32). During TH treatment median RDI was 97% for T and 96% for H, and it was 99% during H treatment. Over 33 P for efficacy analysis (2 consent withdrawal, 1 allergic reaction, 1 ongoing and 4 response not confirmed by RECIST criteria), 6 achieved CR and 12 PR, for an ORR of 54.6% (95% CI: 37.6–71.6). Median follow-up time was 11.8 m and median TTP was 8.8 m (95% CI, 1.9–15.6). All P were evaluable for safety. During TH treatment, grade III/IV neutropenia occurred in 16 cycles (7.4 %), 14 of them were febrile neutropenia episodes (6.5%). Other grade III/IV toxicities per cycle were: leucopenia (5.5%), hyperglycemia (2.3%), anorexia (2.3%) and skin (2.3%). During H monotherapy treatment, the only grade III-IV toxicities observed were, skin (1.6%), oedema (1.1%), nail disorders (0.5%) and malaise (4.3%). Six P (14.6%) dropped out due to cardiac toxicity: 5 had LVEF under 50% and one atrial fibrillation. Conclusions: Preliminary results suggest that TH q3wks followed by H as single agent, is an effective regimen for the treatment of P with Her2 positive MBC. No significant financial relationships to disclose.

Abstract
Single, biocytin filled neurons in combination with immunocytochemistry and retrograde tracing as well as material with traditional double-immunolabeling were used at the light and electron microscopic levels to study the neural circuitry within the basal forebrain. Cholinergic neurons projecting to the frontal cortex exhibited extensive local collaterals terminating on non-cholinergic, (possible GABAergic) neurons within the basal forebrain. Elaborate axon arbors confined to the basal forebrain region also originated from NPY, somatostatin and other non-cholinergic interneurons. It is proposed that putative interneurons together with local collaterals from projection neurons contribute to regional integrative processing in the basal forebrain that may participate in more selective functions, such as attention and cortical plasticity.

Abstract
The basal forebrain (BF) is a heterogeneous structure located in the ventral aspect of the cerebral hemispheres. It contains cholinergic as well as different types of noncholinergic corticopetal neurons and interneurons, including GABAergic and peptidergic cells. The BF constitutes an extrathalamic route to the cortex, and its activity is associated with an increase in cortical release of the neurotransmitter acetylcholine, concomitant with electroencephalographic (EEG) low-voltage fast activity (LVFA). However, the specific role of the different BF cell types has largely remained unknown due to the lack of chemical identification of the recorded neurons. Here we show that the firing rate of immunocytochemically identified cholinergic and parvalbumin-containing neurons increase during cortical LVFA. In contrast, increased neuropeptide Y neuron firing is accompanied by cortical slow waves. Our results, furthermore, indicate that BF neurons posses a distinct temporal relationship to different EEG patterns and suggest a more dynamic interplay within BF as well as between BF and cortical circuitries than previously proposed.

Abstract
In Antioquia and Chocó, traditional healers attend 60% of snakebites. With the aim to produce an inventory of the plants used by the healers to treat snakebites and to document the methods of preparation, administration, the dosage, number of patients treated throughout their years of practice with treatment results, 20 healers with experience in Bothrops, Porthidium and Bothriechis envenomations were interviewed between August, 1996 and November, 1998. They belong to nine black and three indigenous rural communities located near the towns of Bojayá, Vigía del Fuerte, Unguía (Atrato river valley), Nuquí and Bahía Solano (Pacific coast). Based on field interviews, 101 species of plants were identified as used to treat snakebites. The part used of each plant varies according to the species. Sixty plants are used in the form of drinks prepared by infusion, decoction or maceration; 78 as external baths on the affected extremity; 11 for steam application and 39 for poultices; the latter is used mainly when the bite is complicated by local necrosis. In mild and moderate envenomations, they generally use a mixture of three plants, while in severe cases they mix from five to 12, a handful of each one. Treatment is generally performed for 1-3 days, when the patient reacts positively. They reported to have treated 454 patients during their years of experience, 20 of them (4.4%) died. With the guidance of the healers, 77 species of plants were collected and photographed. These plants belong to 41 families, of which Piperaceae (13 species), Araceae (six species), Asteraceae (five species) and Gesneriaceae (three species) have the highest number of species.

Abstract
AIMS The aim of this cohort study was to estimate the risk of clinical acute liver injury among users of oral antifungals identified in the general population of the General Practice Research Database in UK. METHODS The cohort included 69 830 patients, 20-79 years old, free of liver and systemic disease, who had received at least one prescription for either oral fluconazole, griseofulvin, itraconazole, ketoconazole, or terbinafine between 1991 and 1996. RESULTS Sixteen cases of acute liver injury were identified and validated. Ten cases occurred during nonuse of oral antifungals with a background rate of 0.6 per 100,000 person-months (95% confidence interval 0.3,1.1). Five cases occurred during current use of oral antifungals. Two were using ketoconazole, another two itraconazole, and one terbinafine. Incidence rates of acute liver injury were 134.1 per 100 000 person-months (36.8,488.0) for ketoconazole, 10.4 (2.9-38.1) for itraconazole, and 2.5 (0.4,13. 9) for terbinafine. The remaining case was associated with past use of fluconazole. Ketoconazole was the antifungal associated with the highest relative risk, 228.0 (95% confidence interval 33.9,933.0), when compared with the risk among nonusers, followed by itraconazole and terbinafine with relative risks of 17.7 (2.6,72.6) and 4.2 (0.2, 24.9), respectively. CONCLUSIONS Ketoconazole and itraconazole were the two oral antifungal associated with a marked increase of clinical acute liver injury. The risk associated with ketoconazole should be taken into account when prescribing it as initial treatment for uncomplicated fungal infections.

Abstract
The methodological quality of 50 clinical trial protocols submitted to our hospital has been assessed by means of a check-list. The most frequent methodological deficiencies found were related to statistical analysis, selection criteria, sample size, incorrect use of placebo, homogeneity of the groups, concomitant medication, randomisation plan, monitoring of adverse events and study design. Lack of insurance for the patients and inadequacies in the investigators' brochure and case report forms were observed in a significant number of cases. The results suggest the importance of a multidisciplinary team in the elaboration of clinical trial protocols to prevent methodological errors.

Abstract
Taking into account previous results with epirubicin in colorectal cancer, in January, 1985, an oriented Phase II trial was started in patients with measurable rectal cancer, previously untreated with chemotherapy. Ten patients were treated with 80 mg/m2 every 3 weeks, and another 10 patients with 100 mg/m2 every 3 weeks. One patient from the 80 mg/m2 group and 3 from the 100 mg/m2 group reached partial remission for 4, 9+, 15 and 72+ weeks. Median survival for all patients was 16 months. Hematological toxicity was not a limiting factor. Anemia was significantly more frequent in the higher dose group; clinical cardiotoxicity was not observed. The incidences of nausea/vomiting and mucositis were low. Considering the low toxicity and the responses observed, additional studies seem to be indicated with an increase in the epirubicin dose.
