Abstract
Globally increasing concern related to municipal solid waste generation is encouraging research efforts on developing alternative routes to valorize mixed refused wastes. In this way, catalytic pyrolysis is emerging as an interesting and efficient technology due to its great flexibility in terms of feedstock. In the current work, upgrading of a Solid Recovered Fuel (SRF) has been investigated by catalytic pyrolysis over nanocrystalline ZSM-5 zeolite (n-ZSM-5), paying special attention to dechlorination effects due to the high Cl content of the raw waste. Thus, pretreatment of the SRF by water washing and mild thermal processing allows for a significant reduction of the Cl concentration. Regarding the catalytic pyrolysis step, the best conditions correspond with a temperature of 400 °C in the catalyst bed and 0.50 catalyst/SRF mass ratio, which lead to ca. 30 wt% oil yield (rich in aromatic hydrocarbons) together with about 40 wt% gas yield (rich in C3-C4 olefins). Accordingly, these products could find use as raw chemicals or for the production of advanced fuels. In addition, zeolite reutilization has been tested for several cycles, denoting a progressive modification of the products distribution because of coke deposition. However, an almost total recovery of the n-ZSM-5 zeolite catalytic performance is achieved after regeneration by air calcination, affording the production of an oil fraction with a Cl content as low as 40 ppm.

Abstract
Abstract
Background
Catheter ablation is an established therapy for paroxysmal atrial fibrillation (PAF). The TactiFlex™ Ablation Catheter, Sensor-Enabled™ (TactiFlex SE) is a next-generation radiofrequency ablation catheter incorporating highly accurate fiber optics-based contact force sensing technology with a flexible, laser-cut tip.
Purpose
To demonstrate that ablation with TactiFlex SE is safe and effective for the treatment of drug refractory, symptomatic PAF.
Methods
The TactiFlex AF IDE is a prospective, non-randomized, multi-center clinical study which enrolled 355 subjects worldwide. Enrollment in the main study began on June 26, 2020 and completed on June 18, 2021. Subjects underwent de novo Pulmonary Vein Isolation (PVI) and, if indicated, a Cavotricuspid Isthmus ablation (CTI line) for CTI-dependent atrial flutter.
Results
Subjects were divided into two as treated subgroups: High Standard Power (HSP, n=189), defined as subjects with 100% of left atrial lesions ablated at ≥40 W, and Low Standard Power (LSP, n=119), defined as subjects with at least one left atrial lesion ablated at <40W. First pass success, defined as isolation of all pulmonary veins (PVs) confirmed after a minimum 20 min waiting period was achieved in 93.5% (175/186) and 84.5% (98/116) of HSP and LSP subjects, respectively (p=0.0104). Significant decreases in the HSP versus LSP procedures were also seen in total procedure time (112.0 min [89.0, 139.5] and 149.0 [115.0, 182.0], respectively [p<0.001]), total RF time for PV ablation (14.0 min [11.0, 19.0] and 29.0 [19.0, 41.0], respectively [p<0.0001]), total fluoroscopy time (4.0 min [0.0, 11.0] and 8.0 [3.0, 17.0], respectively [p<0.0001]) and irrigation fluid volume (378.0 mL [310.0, 466.0] and 636.0 [476.0, 829.0], respectively [p<0.0001]) (values given as Median [Q1, Q3]), see Figure 1. Both HSP and LSP subjects had a low rate of repeat procedures (1.6% [3/182] and 4.3% [5/115], respectively [p=0.2684]) and primary safety endpoint events (4.8% [9/189] and 4.2% [5/119], respectively [p=0.8182]) through 90 days post-index procedure.
Conclusion
The acute data on the TactiFlex SE catheter demonstrates safe and effective treatment of PAF using either a HSP or LSP ablation strategy. Ablation procedures performed using a HSP strategy were shorter and required less irrigation fluid and fluoroscopy. It is anticipated these results will be reflected in the 12-month safety and effectiveness primary endpoints.

The TactiFlex Ablation Catheter, Sensor-Enabled (TactiFlex SE) is a next-generation radiofrequency ablation catheter incorporating highly accurate fiber optics-based contact force sensing technology with a flexible, laser-cut tip. This is the first report of results from the TactiFlex IDE clinical study.
Purpose
To demonstrate that ablation with TactiFlex SE is safe and effective for the treatment of drug refractory, symptomatic PAF.
Methods
The TactiFlex IDE (NCT04356040) is a prospective, non-randomized, multi-center clinical study which enrolled 305 subjects worldwide in the main study. Enrollment in the main study began on June 26, 2020 and completed on June 8, 2021. Subjects underwent de novo Pulmonary Vein Isolation (PVI) and, if indicated, a Cavotricuspid Isthmus ablation (CTI line) for CTI-dependent atrial flutter.
Results
Acute procedural success was achieved in 98.6% (274/278) of the main study cohort who underwent an ablation procedure using the TactiFlex SE. First pass success, defined as isolation of all pulmonary veins (PVs) confirmed after a minimum 20 min waiting period was achieved in 89.6% (249/278) of subjects. This was a significant improvement versus the TactiSense IDE trial (TactiCath Ablation Catheter, Sensor-Enabled). Significant decreases were also seen in total procedure time (123 min [101.0, 163.5]), total PV ablation time (55.5 min [35.0, 81.0]), total fluoroscopy time (6.0 min [0.0, 13.0]) and irrigation fluid volume (450.0 mL [346.0, 636.0]) (values given as Median [Q1, Q3]), see FIGURE. All subjects have completed at least 90 days of follow-up. Only 2.6% (7/271) of subjects required a repeat procedure during the 90-day blanking period. The primary safety and effectiveness endpoints will be evaluated at 12-months. At 90 days, 4.3% (12/281) subjects had experienced a primary safety endpoint event.
Conclusions
The acute data from the TactiFlex IDE clinical study demonstrate safety and effectiveness of the TactiFlex SE catheter in the treatment of PAF. Ablation procedures performed using the next-generation TactiFlex SE catheter were shorter and had improved acute clinical effectiveness outcomes versus the TactiSense IDE. It is anticipated these results will also be reflected in the 12-month safety and effectiveness endpoints.

Abstract
BACKGROUND Stroke is the second cause of death and the first cause of disability in Europe. The number of stroke patients shows a rapidly increasing due to the increase in the elderly population. The aim of this meta-analysis is to evaluate the prevalence and incidence of stroke in Europe. METHOD We conducted a literature search in MEDLINE, SCOPUS, CINAHL Complete and EMBASE, using the keywords "stroke", "cerebrovascular accident", "epidemiology", "prevalence", "incidence" and "Europe". In order to evaluate the quality and risk of bias, we used the Hoy's modified scale for prevalence studies and the Newcastle Ottawa Scale for incidence studies. A random effects model with 95% confidence intervals (95%CI) was used for the meta-analysis. The I2 statistic was applied to assess heterogeneity. RESULTS The prevalence of stroke in Europe adjusted for sex was estimated at 9.2% (95%CI: 4.4-14.0). The prevalence was 9.1% (95%CI: 4.7-13.6) in men and 9.2% (95%CI: 4.1-14.4) in women, and increased with age. The incidence of stroke in Europe adjusted for sex was 191.9 per 100,000 person-years (95%CI: 156.4-227.3); it was 195.7 per 100,000 person-years (95%CI: 142.4-249.0) in men and 188.1 per 100,000 person-years (95%CI: 138.6-237.7) in women. Again, these rates increased with age. CONCLUSION The prevalence of stroke in Europe is 9.2%. The incidence of stroke in Europe is 191.9 per 100,000 person-years. The prevalence of stroke has increased, whereas the incidence of stroke is stable in comparison with studies conducted at the beginning of the 21st century.

Abstract
The human ingestion of mercury (Hg) from sea food is of big concern worldwide due to adverse health effects, and more specifically if shark consumption constitutes a regular part of the human diet. In this study, the total mercury (THg) concentration in muscle tissue were determined in six sympatric shark species found in a fishing vessel seized in the Galapagos Marine Reserve in 2017. The THg concentrations in shark muscle samples (n = 73) varied from 0.73 mg kg-1 in bigeye thresher sharks (Alopias superciliosus) to 8.29 mg kg-1 in silky sharks (Carcharhinus falciformis). A typical pattern of Hg bioaccumulation was observed for all shark species, with significant correlation between THg concentration and shark size for bigeye thresher sharks, pelagic thresher sharks (Alopias pelagicus) and silky sharks. Regarding human health concerns, the THg mean concentration exceeded the maximum weekly intake fish serving in all the studied species. Mass-Dependent Fractionation (MDF, δ202Hg values) and Mass-Independent Fractionation (MIF, Δ199Hg values) of Hg in whitetip sharks (Carcharhinus longimanus) and silky sharks, ranged from 0.70‰ to 1.08‰, and from 1.97‰ to 2.89‰, respectively. These high values suggest that both species are feeding in the epipelagic zone (i.e. upper 200 m of the water column). While, blue sharks (Prionace glauca), scalloped hammerhead sharks (Shyrna lewini) and thresher sharks were characterized by lower Δ199Hg and δ202Hg values, indicating that these species may focus their foraging behavior on prey of mesopelagic zone (i.e. between 200 and 1000 m depth). In conclusion, the determination of THg concentration provides straight-forward evidence of the human health risks associated with shark consumption, while mercury isotopic compositions constitute a powerful tool to trace the foraging strategies of these marine predators. CAPSULE: A double approach combining Hg concentrations with stable isotopes ratios allowed to assess ontogeny in common shark species in the area of the Galapagos Marine Reserve and the human health risks concern associated to their consumption.

Abstract
Epigenetic changes have been shown to be associated with both aging process and aging-related diseases. There is evidence regarding the benefits of physical activity on the functionality, cognition, and quality of life of institutionalized older adults, however, the molecular mechanisms involved are not elucidated. The purpose of this pilot study was to investigate the effects of a multimodal exercise intervention on functional outcomes, cognitive performance, quality of life (QOL), epigenetic markers and brain-derived neurotrophic factor (BDNF) levels among institutionalized older adult individuals. Participants (n = 8) without dementia who were aged 73.38 ± 11.28 years and predominantly female (87.5%) were included in this quasi-experimental pilot study. A multimodal exercise protocol (cardiovascular capacity, strength, balance/agility and flexibility, perception and cognition) consisted of twice weekly sessions (60 minutes each) over 8 weeks. Balance (Berg Scale), mobility (Timed Up and Go test), functional capacity (Six-Minute Walk test), cognitive function (Mini-Mental State Examination) and QOL (the World Health Organization Quality of Life-BREF Scale questionnaire) were evaluated before and after the intervention. Blood sample (15 mL) was also collected before and after intervention for analysis of biomarkers global histone H3 acetylation and brain-derived neurotrophic factor levels. Significant improvements were observed in cognitive function, balance, mobility, functional capacity and QOL after the intervention. In addition, a tendency toward an increase in global histone H3 acetylation levels was observed, while brain-derived neurotrophic factor level remained unchanged. This study provided evidence that an 8-week multimodal exercise protocol has a significant effect on ameliorating functional outcomes and QOL in institutionalized older adult individuals. In addition, it was also able to promote cognitive improvement, which seems to be partially related to histone hyperacetylation status. The Ethics Research Committee of Centro Universitário Metodista-IPA, Brazil approved the current study on June 6, 2019 (approval No. 3.376.078).

Abstract
Abstract
Background
Durable PV isolation is the sought-after endpoint to obtain long term success after AF catheter ablation. Evolution in technology improves efficiency, safety and effectiveness in AF catheter ablation.
Purpose
To investigate the effectiveness of different catheter technologies in obtaining durable PV isolation in a real-world practice.
Methods
Retrospective analysis of prospectively collected data of patients undergoing repeat procedures for recurrence of AF or atrial flutter at our institution was performed. Incidence of all PVs being isolated at repeat procedure was recorded and patients 4 groups created based on catheter technology used during index AF ablation procedure (SF: multipored, irrigated catheter; ST: contact force sensor catheter; Cryo: 2nd generation cryobaloon; and STSF: multipored, irrigated, contact force sensing catheter).
Results
We identified 269 subjects undergoing repeat ablation from May 2014 to September 2019. Mean age was 67±9.7 years, 54.6% were males, 74.4% non-paroxysmal AF at the index procedure. The mean CHA2DS2Vasc score was 2.5±0.26, LA size 4.2±0.6 cm, EF 55.3±10%. The mean time from index to redo procedure was 374±331 days. At repeat procedure all veins were isolated in 24% (6/25) who were initially ablated using SF; 36% (8/22) with Cryo; 44% (47/108) with ST; and 74% (84/114) with STSF catheter. (Figure)
Conclusion
Patients undergoing index ablation with STSF catheter technology were significantly more likely to have all 4 PVs isolated at repeat procedure compared to previous generation technology.

Abstract
Abstract
Background
Contact force (CF) ablation of AF with a focus on catheter-tissue contact stability optimizes clinical success and may help the operator to achieve pulmonary vein (PV) isolation in a single encirclement. While it seems evident that first pass isolation reduces procedure time, the effect on long term clinical success has not been reported.
Purpose
To evaluate the relationship between first pass isolation and freedom from atrial tachyarrhythmia recurrence at 1 year after PAF ablation.
Methods
Consecutive de novo PAF ablations were performed with a porous tip contact force catheter in 2017. All ablations used wide-area circumferential ablation and first pass isolation was captured separately for the left and right PVs. CF was held between 10–20 g and the catheter was moved every 10–20 s. RF energy was set at 40W throughout the atrium. Clinical success was defined as freedom from recurrent atrial tachyarrhythmia through 1 year following a 90-day blanking period and freedom from reablation at any time through 1 year.
Results
The population included 157 patients, age 62.7±11.5, 54.8% male, with mean CHA2DS2-VASc score of 2.3±1.5. Mean procedure times were 76.2±29.8 minutes and 89.2% of the ablations were performed with no fluoroscopy. The overall clinical success rate at 1 year was 86.1%. The number of ipsilateral PV pairs that could be isolated in a single pass was significantly associated with 1-year success (p=0.0043). Achieving first pass isolation on even one ipsilateral PV pair vs. neither pair was significantly associated with clinical success (Table).
Conclusion
In a real-world setting, first pass isolation on at least one PV side was predictive of 1 year clinical success in a PAF population ablated with CF.

Abstract
BACKGROUND AND PURPOSE Stroke is the second largest single cause of death in Europe, responsible for 9% and 13% of all deaths in men and women, respectively. There have been large overall declines in stroke mortality rates in the majority of European countries in recent decades. The aim of this study was to analyse trends in mortality caused by stroke in the 28 member countries of the European Union (EU) over the last two decades. METHODS We extracted data for age-standardized stroke mortality rates per 100 000 in the EU for the period 1996-2015 from the World Health Organization database. Joinpoint regression analysis was used to analyse the trends and compute the annual percent change (APC) in the EU as a whole and by country. Analyses were conducted by gender and by European region. RESULTS Mortality from stroke has decreased in the EU over the study period by an average APC of 4.2%. All countries showed downward trends, with the sharpest decreases in Estonia, Portugal and Austria. We recorded statistically significant decreases of 4.2% and 4.3% in mortality rates in men and women, respectively, in the whole EU. Southern and western countries showed the steepest decreases, whereas mortality has increased in northern countries in recent years. CONCLUSIONS Stroke mortality has decreased in the EU, in both sexes, especially in southern and western European countries. Our results could be a reference for the development of primary prevention and acute management of stroke policies focused on countries with higher mortality.

Abstract
Abstract
Background
Atrial fibrillation catheter ablation (CA) is the most frequent arrhythmia ablation and accounts for a significant proportion of treatment cost. Same day discharge (SDD) after paroxysmal atrial fibrillation (PAF) ablation is an attractive strategy for both patients and hospitals.
Objective
To understand the eligibility criteria and outcomes for PAF patients who can safely undergo same day discharge after radiofrequency catheter ablation.
Methods
Patients undergoing CA for PAF were evaluated for SDD at a pre-procedure visit to assess the risk of groin, respiratory, cardiac or bleeding complications. Eligibility criteria for SDD were stable anticoagulation and absence of bleeding history, systolic/diastolic heart failure, or interventional procedures within 60 days, with recommended BMI <35. Patient proximity to the hospital was also considered. Anesthesia included propofol with endotracheal intubation and all patients were ablated with a porous tip contact force catheter (STSF). Patients were on bed rest for 6 hours post-procedure, then ambulated intermittently for 1–2 hours. Discharge followed if they were stable with no evidence of vascular access complications or bleeding. A dedicated RN telephoned patients the following morning to ask a series of standard questions designed to elicit evidence of any complications.
Results
52 procedures were identified for SDD, with 7 patients declining. 45 planned SDD procedures for 43 patients occurred 4/17–6/18. Average age was 57±11 years and CHA2DS2-VASc was 1.5±1.1 at procedure. Procedure time was 69±26 min (IQR: 49 - 84 min) with maximum fluoroscopy usage of 0.2 min and 508±149 mL of fluid infused through the catheter. Two patients stayed overnight due a groin bleed and atelectasis with fever, and one chose to stay for comfort. The remaining 42 discharges occurred after 7.2±1.0 hours in recovery, with no SDD-related complications and no required return visits after the follow-up call. There were 3 AF recurrences (6.7%) as of the 10 week visit.
Conclusion
Appropriate low risk patients identified by simple clinical criteria can be safely discharged the same day after CA of PAF. Further evaluation is required for higher risk patients.

Abstract
We explore opportunities as well as challenges associated with conducting a mixed methods needs assessment using a transformative paradigm. The transformative paradigm is a research framework that centers the experiences of marginalized communities, includes analysis of power differentials that have led to marginalization, and links research findings to actions intended to mitigate disparities. We argue that a community needs assessment is a natural fit for the use of a transformative framework, serving as an entry-point for the development of responsive programmatic and funding decisions. Based on a case study of efforts initiated by a local community health foundation to document disparities in their city, we show how an evaluation team used principles aligned with the transformative framework to guide the design and implementation of a community needs assessment. The needs assessment provided a better understanding of the power of community relationships, demonstrated how lack of trust can continue to constrain community voices, and revealed why agencies must actively support a social justice framework beyond the end of an assessment to ensure transformative change.

Abstract
The efficiency of two white-rot fungi (WRF), Trametes versicolor and Ganoderma lucidum, to eliminate thirteen pharmaceutical pollutants with concomitant biodiesel production from the accumulating lipid content after treatment, was examined. The removal efficiency was studied using both individual and combined strains. The results of individual and combined strains showed a total removal (100%) of diclofenac (DCF), gemfibrozil (GFZ), ibuprofen (IBP), progesterone (PGT) and ranitidine (RNT). Lower removals were achieved for 4-acetamidoantipyrin (AAA), clofibric acid (ACF), atenolol (ATN), caffeine (CFN), carbamazepine (CZP), hydrochlorothiazide (HCT), sulfamethoxazole (SMX) and sulpiride (SPD), although the combination of both strains enhanced the system's efficiency, with removals ranging from 15 to 41%. This increase of the removal efficiency when combining both strains was attributed to the interactions developed between them (i.e., competition). Results from enzymatic and cytochrome P450 examination suggested that both extracellular (laccase, MnP, LiP) and intracellular oxidation mechanisms participate in the biological removal of pharmaceuticals. On the other hand, the "green" potential of the fungal sludge generated during the biological removal process was assessed for biodiesel production by means of one-step direct (in-situ) transformation. This process consists of the simultaneous extraction and conversion of lipids contained in the sludge by catalytic esterification/transesterification using a robust acid heterogeneous Zr-SBA-15 catalyst. This catalytic system provided conversions close to 80% of the saponifiable fraction (including free fatty acids and glycerides) in the presence of high amount of impurities. The overall weight FAME yield, based on the initial dried mass, was close to 30% for both strains.

Abstract
INTRODUCTION The aim of this study is to calculate the theoretical frequency of potential drug interactions (PDI) and their characteristics in the therapeutic plan of hospitalized patients in a Pediatric Intensive Care Unit (PICU). PATIENTS AND METHODS An observational study was conducted which analyzed PICU prescriptions between September and November 2011. The inclusion criteria included to be hospitalized in a PICU, requirements of at least 3 drugs, except those topically applied, either gender, no age limit, no hospital stay required. The Micromedex® 2.0 program was used to detect and classify PDI. RESULTS Of 223 patients, 100 met inclusion criteria, 610 prescriptions were analyzed and 815 drugs were prescribed. 1,240 PDI were detected in 44 patients; 12 patients received more than 10 drugs each, presenting 1,162 PDI (93.7% of total PDI). 8 patients were hospitalized for more than 10 days, presenting 1,035 PDI (83.5% of total PDI). According to PDI theoretical severity, 37.5% were high, 51.7% moderate, 6.7% low and 4.1% contraindicated. The therapeutic group most involved was antimicrobials (17.6%) and the most frequently involved individual drugs were chloral hydrate (15.9%), midazolam (14.1%) and vecuronium (13.4%). CONCLUSION PDI were more frequent in patients associated with major polypharmacy and longer hospital stay.

Abstract
In 1991 a manuscript describing an instrument for studying magnetized plasmas was published in this journal. The Large Plasma Device (LAPD) was upgraded in 2001 and has become a national user facility for the study of basic plasma physics. The upgrade as well as diagnostics introduced since then has significantly changed the capabilities of the device. All references to the machine still quote the original RSI paper, which at this time is not appropriate. In this work, the properties of the updated LAPD are presented. The strategy of the machine construction, the available diagnostics, the parameters available for experiments, as well as illustrations of several experiments are presented here.

Abstract
Abstract
A detailed, comprehensive mathematical model for bulk polymerization of styrene using multifunctional initiators – both linear and cyclic – in a batch reactor was developed. The model is based on a kinetic mechanism that considers thermal initiation and chemical initiation by sequential decomposition of labile groups, propagation, transfer to monomer, termination by combination and re-initiation reactions due to undecomposed labile groups. The model predicts the evolution of global reaction variables (e.g, concentration of reagents, products, radical species and labile groups) as well as the evolution of the detailed complete polymer molecular weight distributions, with polymer species characterized by chain length and number of undecomposed labile groups. The mathematical model was adjusted and validated using experimental data for various peroxide-type multifunctional initiators: diethyl ketone triperoxide (DEKTP, cyclic trifunctional), pinacolone diperoxide (PDP, cyclic bifunctional) and 1,1-bis(tert-butylperoxy)cyclohexane (L331, linear bifunctional). The model very adequately predicts polymerization rates and complete molecular weight distributions. The model is used to theoretically evaluate the influence of initiator structure and functionality as well as reaction conditions.

Abstract
All studies attempting to find an association between vitamin D deficiency and cerebrovascular diseases have been conducted at latitudes far away from the Equator, where living conditions, cardiovascular risk factors, and sunshine exposure are different from tropical regions. We aimed to assess cerebrovascular correlates of vitamin D deficiency in community-dwelling older adults living in Atahualpa, a village located in rural coastal Ecuador. Out of 267 individuals enrolled in the neuroimaging substudy of the Atahualpa Project, 220 (82%) signed the informed consent. Mean age of participants was 70·9 ± 7·8 years, and 126 (57%) were women. Fifty-four (25%) persons have vitamin D levels <20 ng/ml, 47 (21%) had ischemic strokes, and 53 (24%) had moderate-to-severe white matter hyperintensities of presumed vascular origin. Exposure effect models constructed with vitamin D deficiency as the exposure, white matter hyperintensities and ischemic stroke as the outcomes, and confounders – age, gender, body mass index, physical activity, blood pressure, fasting glucose, total cholesterol, ionized calcium, phosphorus, intact parathormone, and serum creatinine – as independent variables revealed a significant association of vitamin D deficiency with white matter hyperintensities ( P = 0·006) but not with ischemic strokes ( P = 0·359). This study shows an association of vitamin D deficiency with diffuse subcortical brain damage in older adults living in a tropical region. Lack of awareness of the importance of vitamin D deficiency might be one of the factors influencing the high prevalence of white matter hyperintensities of presumed vascular origin in underserved Latin American populations.

Abstract
Kraft pulp mills use activated sludge systems to remove organic matter from effluents. Process streams may appear as toxic spills in treatment plant effluents, such as black liquor, which is toxic to microorganisms of the activated sludge. The present study evaluates the effects of black liquor shocks in activated sludge systems. Four black liquor shocks from 883 to 3,225 mg chemical oxygen demand-COD L(-1) were applied during 24 hours in a continuously operating lab-scale activated sludge system. Removal efficiencies of COD, color and specific compounds were determined. Moreover, specific oxygen uptake rate (SOUR), sludge volumetric index (SVI) and indicator microorganisms were evaluated. Results show that the addition of black liquor caused an increase in COD removal (76-67%) immediately post shock; followed two days later by a decrease (-19-50%). On the other hand, SOUR ranged between 0.152 and 0.336 mgO2 g(-1) volatile suspended solids-VSS• min(-1) during shocks, but the initial value was reestablished at hour 24. When the COD concentration of the shock was higher than 1,014 mg/L, the abundance of stalked ciliates and rotifers dropped. Finally, no changes in SVI were observed, with values remaining in the range 65.8-40.2 mL g(-1) total suspended solids-TSS during the entire operating process. Based on the results, the principal conclusion is that the activated sludge system with the biomass adapted to the kraft pulp effluent could resist a black liquor shock with 3,225 mgCOD L(-1) of concentration during 24 h, under this study's conditions.

Abstract
The cholesterol content of the sperm membrane is regulated during both maturation in the epididymis and capacitation in the female tract, two processes required for the spermatozoa to acquire their fertilising ability. Because Niemann-Pick disease, type C2 (NPC2) protein is one of the most abundant components of the epididymal fluid and contains a functional cholesterol-binding site that can transfer cholesterol between membranes, it has been suggested for years that NPC2 could be involved in the regulation of cholesterol levels in spermatozoa during epididymal maturation. In the present study, western blot and immunohistochemistry analyses demonstrated significant levels of NPC2 in the mouse epididymal epithelium. Epididymal spermatozoa obtained from NPC2(-/-) mice were morphologically normal and had normal motility parameters, but had a reduced cholesterol content compared with that of wild-type (WT) spermatozoa, as determined by both biochemical and by flow cytometry analyses. These results suggest that NPC2 could be involved in regulating cholesterol levels in spermatozoa during epididymal maturation. To understand the relevance of epididymal NPC2 for sperm function, the ability of spermatozoa to undergo events influenced by epididymal maturation, such as capacitation and fertilisation, were compared between WT and NPC2(-/-) mice. Capacitated NPC2(-/-) spermatozoa exhibited defective tyrosine phosphorylation patterns and a reduced ability to fertilise cumulus-oocyte complexes compared with WT spermatozoa, supporting the relevance of mouse epididymal NPC2 for male fertility.

Abstract
The presentation of myxoma in the neonatal period is quite rare. We report the case of a female patient in whom two cardiac tumors were diagnosed prenatally. Surgery was performed at eight days of age, using cardiopulmonary bypass and circulatory arrest to facilitate excision of two polypoid tumors from within the right atrium. Pathology studies were consistent with myxoma. The postoperative course was satisfactory and the patient was discharged 14 days after surgery, at 22 days old.

Abstract
Niemann-Pick C2 protein (NPC2) is a lysosomal soluble protein that is highly expressed in the liver; it binds to cholesterol and is involved in intracellular cholesterol trafficking, allowing the exit of lysosomal cholesterol obtained via the lipoprotein endocytic pathway. Thus, this protein may play an important role in controlling hepatic cholesterol transport and metabolism. The aim of this work was to study the relevance of NPC2 protein expression in hepatic cholesterol metabolism, biliary lipid secretion and gallstone formation by comparing NPC2 hypomorph [NPC2 (h/h)] and wild-type mice fed control, 2% cholesterol, and lithogenic diets. NPC2 (h/h) mice exhibited resistance to a diet-induced increase in plasma cholesterol levels. When consuming the chow diet, we observed increased biliary cholesterol and phospholipid secretions in NPC2 (h/h) mice. When fed the 2% cholesterol diet, NPC2 (h/h) mice exhibited low and high gallbladder bile cholesterol and phospholipid concentrations, respectively. NPC2 (h/h) mice fed with the lithogenic diet showed reduced biliary cholesterol secretion, gallbladder bile cholesterol saturation, and cholesterol crystal and gallstone formation. This work indicates that hepatic NPC2 expression is an important factor in the regulation of diet-derived cholesterol metabolism and disposal as well as in diet-induced cholesterol gallstone formation in mice.

Abstract
OBJECTIVES To determine the in vitro activity of retapamulin and other topical antibiotics (mupirocin, bacitracin, and fusidic acid) usually employed for nasal decolonization, against methicillin-susceptible Staphylococcus aureus (MSSA), methicillin-resistant S. aureus (MRSA), and linezolid and methicillin-resistant S. aureus. METHODS The minimum inhibitory concentrations (MICs) were determined on Mueller-Hinton agar according to the guidelines of the Clinical and Laboratory Standards Institute and of the European Committee for Antimicrobial Susceptibility Testing. Presence of the cfr gene in linezolid and methicillin-resistant S. aureus isolates was detected using polymerase chain reaction. RESULTS Retapamulin inhibited all the isolates of MSSA and MRSA at 0.125 mg/L, but the 18 linezolid-resistant-MRSA strains proved resistant, with MICs over 32 mg/L. Most MSSA isolates (9/10) were susceptible to mupirocin with MICs under 0.19 mg/L, although this value decreased to half against MRSA, and almost all linezolid-resistant MRSA (17/18) strains were resistant to mupirocin with an MIC range of between 8 mg/L and 28 mg/L. The MIC of fusidic acid increased substantially against linezolid-resistant MRSA, whereas that of bacitracin showed no differences. CONCLUSIONS Retapamulin demonstrated excellent in vitro activity against MSSA and MRSA strains, but not against MRSA isolates harbouring the cfr gene. The results of this in vitro study support cut-off values for retapamulin of ≤ 0.5, 1, and ≥ 2 mg/L for susceptible, intermediate, and resistant strains, respectively.

Abstract
OBJECTIVES Acute urinary retention (AUR) is uncommon in women and can be related to different conditions. Only some patients are referred to the urodynamics units for a more extensive study. We intend to describe the charcteristics and causes of AUR in women referred to our unit and to analyze their middle term evolution. MATERIAL AND METHODS We performed a descriptive retrospective study (January 1982-December 2006), including the women referred to our Uro-Neurology and Urodynamics Unit after suffering an AUR. Medical charts were reviewed with special emphasis on medical history, physical examination, and also complete urodynamics study during the AUR event and after its resolution. RESULTS A total of 202 women were included, median age of 57 years (12-87 years). Prior to the AUR, 59 women (28.7%) reported voiding symptoms. The urodynamics findings were: 65 (32.2%) detrusor hypocontractility; 64 (31.7%) normal study; 37 (18.3%) detrusor acontractility; 21 (10.4%) bladder outlet obstruction; 15 (7.4%) poor pelvic floor relaxation. The causes of the AUR were: 53 neurological (26.2%); 46 unknown (22.8%); 19 gynecological (9.4%); 22 diabetes mellitus (10.9%); 16 urological (7.9%). Renal insufficiency was observed in 14 patients (6.9%). After the AUR 106 women (52.4%) needed some kind of prolonged treatment. CONCLUSIONS In our experience, AUR in the female is mainly related to underlying neurologic/urogynecologic disease, even though the etiology could not be known in a significant percentage of patients. Half of the patients recovered completely and did not require any treatment.

Abstract
AbstractX-ray diffraction (XRD) is generally used to measure crystallographic texture, but complete analysis is rarely performed. Orientation imaging microscopy (OIM) gives similar data by electron diffraction and has potential for widespread use since it may be added to any scanning electron microscope. Analysis software has been developed to reduce QIM results into a form which may be compared directly to XRD results. OIM texture parameters measured from Al films showed good quantitative agreement with XRD parameters, however the texture in Cu films is more complex and difficult to compare. Although subject to certain limitations, OIM has several advantages over XRD including more efficient data collection, better sensitivity to minor texture components, and more flexible data analysis.

Abstract
The electroencephalogram is a technique for the functional exploration of the central nervous system (CNS). It is a relatively old technique but even today it continues to be a tool of great assistance to the clinician in diagnosing and treating certain pathologies, such as epilepsy, encephalopathies, alterations to the state of consciousness, CNS infections, etc. On the other hand, it is a diagnostic tool whose applications are expanding in combination with other neurophysiological techniques, such as in the field of the study and diagnosis of sleep pathology (polysomnography, multiple sleep latency test...) and in intraoperative monitoring together with somasensory evoked potentials. This article describes the basic techniques of electroencephalography, with special emphasis on its main clinical applications and on future perspectives.

Abstract
Narcolepsy is a disease that involves an alteration in the generation and organisation of sleep. The main symptoms are excessive daytime sleepiness and cataplexy, followed by hypnagogic hallucinations, sleep paralysis and disrupted nocturnal sleep. The prevalence of typical narcolepsy oscillates between 25-50: 100.000 in general. Recently there has been a peak incidence in patients born in the month of March. According to the new classification, the Multiple Sleep Latency Test (MSLT) is mandatory for diagnosing narcolepsy without cataplexy, and advisable for diagnosing narcolepsy with cataplexy. Until now, the attempt has been made to control each symptom by its own specific treatment. At present, new American and European treatment guidelines propose new drugs that act on all the symptoms. The application of new criteria of diagnosis and treatment has improved the diagnosis, giving better options of treatment.
