The continuous intravenous administration of isotopic bicarbonate (NaH13CO2) has been used for the determination of the retention of the 13CO2 fraction or the 13CO2 recovered in expired air. This determination is important for the calculation of substrate oxidation. The aim of the present study was to evaluate, in critically ill patients with sepsis under mechanical ventilation, the 13CO2 recovery fraction in expired air after continuous intravenous infusion of NaH13CO2 (3.8 µmol/kg diluted in 0.9% saline in ddH2O). A prospective study was conducted on 10 patients with septic shock between the second and fifth day of sepsis evolution (APACHE II, 25.9 ± 7.4). Initially, baseline CO2 was collected and indirect calorimetry was also performed. A primer of 5 mL NaH13CO2 was administered followed by continuous infusion of 5 mL/h for 6 h. Six CO2 production (VCO2) measurements (30 min each) were made with a portable metabolic cart connected to a respirator and hourly samples of expired air were obtained using a 750-mL gas collecting bag attached to the outlet of the respirator. 13CO2 enrichment in expired air was determined with a mass spectrometer. The patients presented a mean value of VCO2 of 182 ± 52 mL/min during the steady-state phase. The mean recovery fraction was 0.68 ± 0.06%...

In the last years, phototherapy has becoming a promising tool to improve skeletal muscle recovery after exercise, however, it was not compared with other modalities commonly used with this aim. In the present study we compared the short-term effects of cold water immersion therapy (CWIT) and light emitting diode therapy (LEDT) with placebo LEDT on biochemical markers related to skeletal muscle recovery after high-intensity exercise. A randomized double-blind placebo-controlled crossover trial was performed with six male young futsal athletes. They were treated with CWIT (5A degrees C of temperature [SD +/- 1A degrees]), active LEDT (69 LEDs with wavelengths 660/850 nm, 10/30 mW of output power, 30 s of irradiation time per point, and 41.7 J of total energy irradiated per point, total of ten points irradiated) or an identical placebo LEDT 5 min after each of three Wingate cycle tests. Pre-exercise, post-exercise, and post-treatment measurements were taken of blood lactate levels, creatine kinase (CK) activity, and C-reactive protein (CRP) levels. There were no significant differences in the work performed during the three Wingate tests (p > 0.05). All biochemical parameters increased from baseline values (p < 0.05) after the three exercise tests...

Objective - To compare hemodynamic, clinicopathologic, and gastrointestinal motility effects and recovery characteristics of halothane and isoflurane in horses undergoing arthroscopic surgery. Animals - 8 healthy adult horses. Procedure - Anesthesia was maintained with isoflurane or halothane (crossover study). At 6 intervals during anesthesia and surgery, cardiopulmonary variables and related derived values were recorded. Recovery from anesthesia was assessed; gastrointestinal tract motility was subjectively monitored for 72 hours after anesthesia. Horses were administered chromium, and fecal chromium concentration was used to assess intestinal transit time. Venous blood samples were collected for clinicopathologic analyses before and 2, 24, and 48 hours after anesthesia. Results - Compared with halothane-anesthetized horses, cardiac index, oxygen delivery, and heart rate were higher and systemic vascular resistance was lower in isoflurane-anesthetized horses. Mean arterial blood pressure and the dobutamine dose required to maintain blood pressure were similar for both treatments. Duration and quality of recovery from anesthesia did not differ between treatments, although the recovery periods were somewhat shorter with isoflurane. After isoflurane anesthesia...

Objective: The purpose of the present study was to examine insulin secretion in rats submitted to protein restriction and nutritional recovery associated or not to physical training. Methods: The experiment was designed in two sets of five weeks each. In the first set the rats were fed a nonnal-protein diet(17%-control group) or a low-protein diet (6%-malnourished group) for five weeks. After this, all animals were fed the 17% protein diet and separated into four groups: sedentary control(SC); trained eontrol(TC); sedentary recovered(SR) and trained recovered(TR). TC and TR rats performed swimming exercise. Results: The results indicated efficiency of the 6% protein diet in producing signs of malnutrition, as reduction in body weight gain and serum albumin levels, as well as liver fat. Serum insulin in the fed state and insulin secretion by isolated pancreatic islets in response to glucose were Keduced,but peripheral sensitivity to insulin was increased and glucose tolerance was not changed in the protein deficient rats, indicating adaptation to malnutrition. Diet protocol for nutritional recovery was efficient in repairing body weight gain, serum albumin and liver fat levels of the previously malnourished rats. Glucose induced insulin release by pancreatic islets remained low after nutritional recovery. Insulin secretion by the islets isolated from rats submitted to exercise training during nutritional recovery was improved when compared with the sedentary animals. Conclusion: This indicates that exercise training may be useful in the treatment of protein calorie malnutrition...

Drinking water (DW) distribution systems are known to harbour biofilms even in the presence of disinfectants. DW biofilms are constituted by microbial communities adapted to low nutrient concentrations and high chlorine levels. Biofilm formation and resistance to disinfection have been recognized as important factors that contribute to the survival and persistence of microbial contamination in DW. The purpose of this work was the comparison of diverse methods to assess the disinfection of biofilms formed by six DW-isolated opportunistic bacteria (Acinetobacter calcoaceticus, Burkholderia cepacia, Methylobacterium sp., Mycobacterium mucogenicum, Sphingomonas capsulata and Staphylococcus sp.) by sodium hypochlorite (SHC). Single and multi-species biofilms (composed of combinations of 6 and 5 bacteria) were developed in 96- wells microtiter plates for 3 days, afterwards, were exposed to several independent SHC concentrations (0.1, 0.5, 1 and 10 mg/L) during 1 h. The potential of biofilms to recover was assessed 24 h after disinfection. The disinfection efficacy and recovery were assessed in terms of variation in: biofilm mass (crystal violet staining); metabolic activity (XTT staining); cultivability (CFUs) and viability (Live/Dead staining). The results indicated that biomass removal increased with increasing SHC concentration...

Although there has been a lot of research examining the effect of service failures and recovery on customer loyalty in traditional (bricks-and-mortar) services, there is still little rigorous empirical research examining this in e-service settings. The objective of this study is to empirically examine the impact of service failures and service recovery on customer loyalty in e-services. The study is based on data from an online questionnaire of customers of an e-banking service. The results validated the relationships generally found in traditional services: i) service failures result in decreased customer loyalty intentions; ii) effective recovery from failures increases customer loyalty intentions; and iii) unless recovery efforts elicit very high levels of satisfaction from customers, they can, at best, restore loyalty to the levels existing prior to the failures. The implications for the management of e-services are discussed.

After a seagrass beds (Zostera noltii) colapse in 2008 of the Mira estuary (SW coast of Portugal) symptoms of early recovery were observed. The principal goal of this study is to assess the evolution and resilience of the benthic nematodes assemblages during the natural recovery of the seagrass beds through analysis of the spatial and temporal differences in structural and functional characteristics of the communities. The horizontal macroscale (km) and small scale (m) variability was evaluate. We hypothesize that the new environmental conditions of the early recovery, with sparsely distributed and small-sized seagrass patches, will increase the spatial heterogeneity of nematode communities and significantly affect community diversity, both taxonomic and functional. The sampling design was follows: Samples were collected in five “occasions”, (February, June, September, December 2010 and February 2011), at randomly “stations” located over a distance 50 m, at two “sites”, 2km distance. To test the hypothesis that the composition of nematodes assemblages changes spatially and seasonally a two–way PERMANOVA analysis was performed. Mean nematode densities varied between 1416 ± 107 ind. 10 cm-2 (Site A) and 2611 ± 230 ind. 10 cm-2 (Site B) ...

Human adenoviruses (HAdV) and hepatitis A virus (HAV) are shed in the faeces and consequently may be present in environmental waters, resulting in an increase in pathogen concentration that can affect water quality and human health. The aim of this study was to evaluate an adsorption-elution method which utilizes negatively charged membrane HA to determine the efficient recovery of HAdV and HAV from different water matrices and to combine this procedure with a qualitative molecular method (nested RT-PCR and nested PCR). The best efficiency recovery was achieved in distilled water and treated wastewater effluent (100%) for both viruses and in recreational lagoon water for HAV (100%). The efficiency recovery was 10% for HAdV and HAV in seawater and 10% for HAdV in lagoon water. The viral detection limit by nested PCR for HAV in water samples ranged between 20-0.2 FFU/mL and 250 and 25 TCID50/mL for HAdV. In conclusion, these results suggest that the HA negatively charged membranes vary their efficiency for recovery of viral concentration depending upon the types of both enteric viruses and water matrices.

Cyclosporin-A (CsA) is an immunosuppressive drug that acts as an inhibitor of calcineurin, a calcium phosphatase that has been suggested to play a role in skeletal muscle hypertrophy. The aim of the present study was to determine the effect of CsA administration (25 mg kg-1 day-1) on skeletal muscle mass and phenotype during disuse and recovery. Male Wistar rats received vehicle (N = 8) or CsA (N = 8) during hind limb immobilization (N = 8) and recovery (N = 8). Muscle weight (dry/wet) and cross-sectional area were evaluated to verify the effect of CsA treatment on muscle mass. Muscle phenotype was assessed by histochemistry of myosin ATPase. CsA administration during immobilization and recovery did not change muscle/body weight ratio in the soleus (SOL) or plantaris (PL). Regarding muscle phenotype, we observed a consistent slow-to-fast shift in all experimental groups (immobilized only, receiving CsA only, and immobilized receiving CsA) as compared to control in both SOL and PL (P < 0.05). During recovery, no difference was observed in SOL or PL fiber type composition between the experimental recovered group and recovered group receiving CsA compared to their respective controls. Considering the muscle/body weight ratio, CsA administration does not maximize muscle mass loss induced by immobilization. Our results also indicate that CsA fails to block skeletal muscle regrowth after disuse. The present data suggest that calcineurin inhibition by CsA modulates muscle phenotype rather than muscle mass.

Previous works have studied how to use proactive recovery to build intrusion-tolerant replicated systems that are resilient to any number of faults, as long as recoveries are faster than an upper-bound on fault production assumed at system deployment time. In this work, we propose a complementary approach that combines proactive recovery with services that allow correct replicas to react and recover replicas that they detect or suspect to be compromised. One key feature of our proactive-reactive recovery approach is that, despite recoveries, it guarantees the availability of the minimum amount of system replicas necessary to sustain system's correct operation. We design a proactive-reactive recovery service based on a hybrid distributed system model and show, as a case study, how this service can effectively be used to augment the resilience of an intrusion-tolerant firewall adequate for the protection of critical infrastructures

Schizophrenia has traditionally been viewed as a chronic condition with a very pessimistic outlook, but that assumption may not be valid. There has been a growing consumer movement among people with schizophrenia that has challenged both the traditional perspective on the course of illness and the associated assumptions about the possibility of people with the illness living a productive and satisfying life. This new conception of the illness is supported by long-term studies that suggest that as much as 50% of people with the illness have good outcomes. There has also been a change in political and public health perspectives of the illness, stimulated in part by the President's New Freedom Commission on Mental Health. The purpose of this article is to provide an overview of some key themes about the recovery concept, as applied to schizophrenia. The article will address 3 questions: (1) What is recovery? (2) Is recovery possible? and (3) What are the implications of a recovery model for a scientific approach to treatment (ie, the use of evidence-based practices)? Scientific and consumer models of recovery are described, and commonalities and differences are discussed. Priorities for future research are suggested.

DINÂMIA, Outubro de 2008.; This paper assesses the situation in Portugal in 2005 regarding cost recovery in the water supply (WS) and wastewaterdrainage and treatment (WWDT) industry by type of system (bulk and retail water and wastewater), by type of utility and by NUTS III, halfway between the publication of the Water Framework Directive (WFD) and the meeting of the 2010 deadline. For that purpose, we build on the previous contribution by Monteiro (2007), which reported the situation in 2002, by updating the indicators to 2005 and assessing the evolution since 1998. We also present a brief historical overview of the presence of the cost recovery principle in Portuguese law regarding the industry. The main conclusions that stand out are: the introduction of the cost recovery principle is prior to the WFD and the more recent Water Law, although it lacked practical implementation; the level of revenues collected by the WS and WWDT utilities is insufficient to meet the financial costs of their activities; the situation is worse for wastewater than for WS systems, revealing evidence of cross-subsidization within the utilities which manage both systems; the situation has worsened in recent years; cost recovery levels are lower in the less densely populated and poorer inland regions; finally...

Although the long-term effects of disasters and the factors that affect the ability to recover have received increasing attention from social science researchers, little systematic research has been conducted on the processes and outcomes associated with business disaster recovery. This paper attempts to fill that void by exploring the determinants of recovery within the private sector. We develop a model of business recovery by drawing from existing research on disaster recovery and on organizational survival in non-disaster contexts, and test it using data collected from a stratified random sample of 1110 Los Angeles area firms affected by the 1994 Northridge earthquake. Business size, disruption of busiiess operations due to the earthquake, earthquake shaking intensity, and the utilization of external post-disaster aid are all predictors of business recovery. Size helps businesses weather disaster losses, just as it proves advantageous in non-disaster contexts. How businesses fare following disasters depends not only on direct physical impacts, but also on how disasters subsequently affect business operations as well as on ecological and neighborhood-level impacts. The aid available to businesses following disasters not only doesn’t appear to help them recover; it may actually create additional problems...

While the long-term effects of disaster and the factors that affect the ability to recover have received increasing attention by social science researchers, the majority of research to date has taken families and households as the units of analysis, with a smaller number of studies focusing on the recovery of entire communities. The processes and outcomes associated with the recovery of private firms, however, have almost never been addressed in the literature. Studies of the long-term economic consequences of disasters have generally focused on aggregate community effects. Findings of this research suggest that disasters produce negligible impacts at the community level. While important, this type of research neglects the impacts of disasters on individual firms and overlooks important micro-level recovery processes. For example, empirical support exists for the notion that disasters create both winners and losers, a process that aggregate analyses cannot capture. With this in mind, this paper explores the distributive effects of disaster on 1110 Los Angeles area firms impacted by the 1994 Northridge earthquake. The model used to predict winners and losers is based on an earlier analysis of business recovery following the earthquake...

This work is part of an exploratory study that seeks to describe the levels of community-scale building damage and socio-economic disruption following the January 2010 Haiti earthquake. Damage and disruption were analyzed for pre-event, post-event, and early recovery time periods in seven Haitian communities. Specifically here, remote sensing analysis related to early recovery and a remote sensing-based early recovery scale are presented. Damage datasets from the GEO-CAN post-disaster assessment were combined with analyses of fine resolution satellite imagery, captured 4 months after the earthquake, to quantify the early recovery status of damaged buildings. Disruption was established from community-level interviews conducted in May 2010. Preliminary results show little correlation between disruption and physical damage, although the integration of remote sensing, field data, interviews and community meetings was a successful approach for assessing disruption. Remote sensing was seen to be an effective tool in establishing levels of early recovery and supporting cross-community comparisons.

Efficient recovery of precious metals from process solutions is essential for improving process economics. Traditionally, precious metals are relatively effectively recovered from waste streams via precipitation or cementation. However, these approaches have a number of drawbacks, including poor water balance, creation of environmentally unfriendly waste streams, and losses of precious metals. Ion exchange technology is an alternative for the recovery of precious metals from waste or low-grade streams. This technology allows the recovery of the precious metals to extremely low levels (micrograms per litre) with relatively high upgrade ratios from the solution onto the resin without major water balance concerns, while the impact on the environment could be minimized or avoided. Research was conducted on the recovery of platinum group metals and gold from different low-grade and waste streams from one of the precious metals refineries in South Africa by means of ion exchange. Various functionalities and matrices (granular and fibrous) of ion exchange materials were evaluated. The results from these studies indicated that in some cases ion exchange could be very effective for the recovery of precious metals, and that the PGM concentration could be reduced to < 1 mg/L. The upgrading ratios of the various PGMs onto the specific fibres were relatively high for the specific streams evaluated...
