Abstract
Opioid-dependent immune-mediated analgesic effects have been broadly reported upon inflammation. In preclinical mouse models of intestinal inflammatory diseases, the local release of enkephalins (endogenous opioids) by colitogenic T lymphocytes alleviate inflammation-induced pain by down-modulating gut-innervating nociceptor activation in periphery. In this study, we wondered whether this immune cell-derived enkephalin-mediated regulation of the nociceptor activity also operates under steady state conditions. Here, we show that chimeric mice engrafted with enkephalin-deficient bone marrow cells exhibit not only visceral hypersensitivity but also an increase in both epithelial paracellular and transcellular permeability, an alteration of the microbial topography resulting in increased bacteria-epithelium interactions and a higher frequency of IgA-producing plasma cells in Peyer's patches. All these alterations of the intestinal homeostasis are associated with an anxiety-like behavior despite the absence of an overt inflammation as observed in patients with irritable bowel syndrome. Thus, our results show that immune cell-derived enkephalins play a pivotal role in maintaining gut homeostasis and normal behavior in mice. Because a defect in the mucosal opioid system remarkably mimics some major clinical symptoms of the irritable bowel syndrome, its identification might help to stratify subgroups of patients.

Abstract
Many bacteria of the genus Bradyrhizobium are capable of inducing nodules in legumes. In this work, the importance of a type VI secretion system (T6SS) in a symbiotic strain of the genus Bradyrhizobium is described. T6SS of Bradyrhizobium sp. LmicA16 (A16) is necessary for efficient nodulation with Lupinus micranthus and Lupinus angustifolius. A mutant in the gene vgrG, coding for a component of the T6SS nanostructure, induced less nodules and smaller plants than the wild-type (wt) strain and was less competitive when co-inoculated with the wt strain. A16 T6SS genes are organized in a 26-kb DNA region in two divergent gene clusters of nine genes each. One of these genes codes for a protein (Tsb1) of unknown function but containing a methyltransferase domain. A tsb1 mutant showed an intermediate symbiotic phenotype regarding vgrG mutant and higher mucoidity than the wt strain in free-living conditions. T6SS promoter fusions to the lacZ reporter indicate expression in nodules but not in free-living cells grown in different media and conditions. The analysis of nodule structure revealed that the level of nodule colonization was significantly reduced in the mutants with respect to the wt strain.

Abstract
Introduction The SARS–Cov2 pandemic has made it necessary to implement drastic measures to contain the infection and at the same time start a regulated process of protection of health workers (OS) and hospitalized patients (PR). Objective To verify the effectiveness of the health surveillance measures for SARS–COoV2 infection put in place to protect the OS and PR in the Cardiology of the Gubbio–Gualdo Tadino Hospital (AUSL Umbria 1). Material and methods we conducted a retrospective analysis, in the period 1 April 2020– 30 November 2021, on OS and PR in our Cardiology–UTIC OU. The protocols used for health surveillance provided, in all phases of the pandemic, the well–known general prevention measures (PPE, hand hygiene, distancing, per–triage). In phase 1 of the pandemic, molecular swabs were also carried out every 14 days at the OS and only at the entrance to the PR, in phase 2 antigenic tests every 5 days at the OS and molecular swabs at the entrance and after 48 hours at the PR while in the current phase 3 an antigenic test every 10 days at the OS and PR a molecular swab at T0 and T2 and an antigenic test at the 5th day and subsequently every 5 days. Results A total of 320 subjects, a sample of PR (300, 15 patients month) and all OS (20) were analyzed. A total of 2658 swabs were carried out (1088 molecular and 1570 antigenic) and only two positive OS were found in phase 1 of the pandemic alone, while in phase 2 and 3 no OS or PR was positive. Conclusions The application of the general rules for the prevention of SARS–Cov2 infection and the definition of precise intra–hospital pathways, together with the application of a hospital health surveillance protocol, has made it possible to significantly limit infections within the OU. In addition, the rapid identification of positive OS allowed for rapid isolation avoiding the spread of infection to PR and other OS. Bibliography: COVID and gender resources.

Abstract
Abstract
Introduction
Scientific studies have shown that hypoglycaemia is an important risk factor for adverse events in cardiac intensive care. Nursing management of blood glucose, via protocol, is an important tool to avoid cases of hypoglycaemia.
Objective
We evaluate the efficacy and safety of a glycemia control protocol based on nursing management in diabetic patients in Intensive Care Unit.
Material and methods
We conducted a retrospective analysis on 500 patients hospitalized for acute coronary syndrome or heart failure, with an average age of 75±12 years, clinically stable. The protocol used provides, on medical indication, the suspension of home therapy (both oral hypoglycemic agents and insulin) and the introduction of insulin therapy according to the scheme 0.2/0.5 IU/kg/day. The dosage lower than 0.2 IU/kg/day is used for patients in home therapy with oral hypoglycemic agents and basal blood sugar <150 mg/dl and the dose greater than 0.5 IU/kg/day for patients already on home insulin therapy and basal blood sugar> at 200 mg/dl. The intermediate dosage. 3–0.4 IU/kg/day is instead used in patients with glycaemia between 150 and 200 mg/dl regardless of home therapy. On the basis of the dosage schedule, the daily insulin requirement is obtained which is then administered at 50% as a slow analogue at 10 pm and at 50% as a rapid analogue, further divided into three doses with each main meal.
Once the initial therapy has been set, the nurse acts autonomously according to a correction algorithm (based on the calculation of the correction factor (FC) according to the formula FC = 3000/body weight in kg or FC = 1700/total daily dose of insulin > FC = reduction in blood glucose in mg/dl determined by 1 IU of insulin) which provides for the modification of insulin therapy based on the patient's weight and the blood glucose values measured with sticks at 8, 12, 18 and 22. If during hospitalization and/or discharge, inadequately controlled glycemic values persist, the patient is sent to diabetes advice and the current home therapy is resumed upon discharge or according to diabetes advice.
Results
We observed an excellent pre and post prandial glucose control with extremely reduced incidence of hypoglycaemia which occurred in only 3 cases, one of which with severe hypoglycaemia (glucose detected <40 mg/dl, resolved with the administration of glucose 33 20ml% followed by infusion of 10% glucose solution and glycemic stick after 15') for administration error and two with moderate hypoglycaemia (glucose detected between 40–70 mg/dl resolved with the reduction of 2 IU of rapid analogue and repeated stick post prandial).
Conclusions
A nursing management protocol for blood glucose values in patients with diabetes mellitus hospitalized for acute coronary syndrome or heart failure is safe and allows good control of blood glucose values.

Abstract
Chronic obstructive pulmonary disease (COPD) is expected to be the 3rd leading cause of death worldwide by 2020. Despite improvements in survival by using acute non-invasive ventilation (NIV) to treat patients with exacerbations of COPD complicated by acute hypercapnic respiratory failure (AHRF), these patients are at high risk of readmission and further life-threatening events, including death. Recent studies suggested that NIV at home can reduce readmissions, but in a small proportion of patients, and with a high level of expertise. Other studies, however, do not show any benefit of home NIV. This could be related to the fact that respiratory failure in patients with stable COPD and their response to mechanical ventilation are influenced by several pathophysiological factors which frequently coexist in the same patient to varying degrees. These pathophysiological factors might influence the success of home NIV in stable COPD, thus long-term NIV specifically adapted to a patient's "phenotype" is likely to improve prognosis, reduce readmission to hospital, and prevent death. In view of this conundrum, Rescue2-monitor (R2M), an open-label, prospective randomized, controlled study performed in patients with hypercapnic COPD post-AHRF, will investigate the impact of the quality of nocturnal NIV on the readmission-free survival. The primary objective is to show that any of 3 home NIV strategies ("rescue," "non-targeted," and "targeted") will improve readmission-free survival in comparison to no-home NIV. The "targeted" group of patients will receive a treatment with personalized (targeted) ventilation settings and extensive monitoring. Furthermore, the influence of comorbidities typical for COPD patients, such as cardiac insufficiency, OSA, or associated asthma, on ventilation outcomes will be taken into consideration and reasons for non-inclusion of patients will be recorded in order to evaluate the percentage of ventilated COPD patients that are screening failures.

Abstract
Ewing sarcoma (ES) is a primary bone marrow tumor that very rarely develops in extra-osseous tissues, such as lung. The hallmark of ES tumors is a translocation between chromosomes 11 and 22, resulting in a fusion protein, commonly referred to as EWS-FLI1. The epigenetic profile (histone acetylation and methylation enrichment of the promoter region) that may regulate the expression of the aberrant transcription factor EWS-FLI1, remains poorly studied and understood. Knowledge of epigenetic patterns associated with covalent histone modification and expression of enzymes associated with this process, can contribute to the understanding of the molecular basis of the disease, as well as to the identification of possible molecular targets involved in expression of the EWS-FLI1 gene, so that therapeutic strategies may be improved in the future. In the present study, the transcriptional activation and repression of the EWS-FLI1 fusion gene in ES was accompanied by selective deposition of histone markers on its promoter. The EWS-FLI1 fusion gene was evaluated in two patients with ES using conventional cytogenetic, fluorescence in situ hybridization and nested PCR assays, which revealed that the aberrant expression of the EWS-FLI1 gene is accompanied by enrichment of H3K4Me3, H3K9ac and H3K27ac at the promoter region.

Abstract
Background Work-related stressors, including role ambiguity and role conflict, are related to psychological maladjustment and mental ill-health. However, to date, the role of personal resources such as emotion-regulation ability (ERA) in the prediction of mental health indicators has not been addressed. Aims To examine whether ERA would contribute to explaining teachers' depression, anxiety and stress symptoms beyond role ambiguity and role conflict. Methods We carried out a cross-sectional questionnaire survey. We used a correlation matrix and hierarchical regression models to analyse the data. Results Three hundred and thirty-six Spanish teachers (185 female) from several grade levels completed the surveys (40% response rate). Role ambiguity and role conflict were positively related to depression, anxiety and stress symptoms. ERA was negatively related to teachers' scores on depressive, anxious and stress symptoms, with predictive power above the main effects of role ambiguity and role conflict. An interaction between role ambiguity and ERA was also significant in predicting depression. Conclusions Our study provides preliminary evidence suggesting the development of integrative models considering work-related stressors along with personal resources such as ERA aiming to prevent teachers' mental ill-health. Future studies should examine the influence of ERA on psychological symptoms using longitudinal designs.

Abstract
The objective of this study was to evaluate the effects of replacing rye-grass (Lolium spp.) hay with banana (Musa acuminata L.) by-products on feed intake, average daily gain (ADG), and feed conversion rate (FCR) in Pelibuey (hair sheep breed) lambs. The lambs (n = 22; initial BW = 14.8 ± 2.5 kg) were individually housed and fed on two different types of diet for 58 days: the first group (experimental diet) received as forage a mixture of fresh banana by-products composed of leaves and pseudostem. The second group received commercial rye-grass hay (conventional diet) as a fiber source. Both groups received a supplementary commercial concentrate food. The total daily forage intake and FCR were lower (P < 0.001) in animals fed on the conventional diet (rye-grass hay) than animals fed on the experimental diet (banana by-products). However, there were no significant differences in total dry matter intake, total digestible energy intake, total body weight gain, and ADG between the two groups. The results obtained in this study suggest that banana by-products could be used as alternative forage for Pelibuey lambs raised in subtropical conditions.

Abstract
Les comportements alimentaires de la population néolithique de Gurgy « Les Noisats » (Yonne, Vemillénaire av. J.-C.) sont étudiés à travers l'analyse des ratios isotopiques du collagène osseux de 40 sujets. Cette nécropole correspond à l'une des plus importantes du Néolithique français : elle compte 126 inhumations primaires sur une période d'occupation de près d'un millénaire. Au cœur d'une région située à l'intersection entre plusieurs cultures, la grande diversité des dispositifs funéraires et du mobilier atteste des multiples influences alentour. Les résultats isotopiques (δ13C et δ15N) des humains comparés à la faune régionale soulignent l'importance des protéines animales issues de l'élevage (viande ou produits laitiers) — voire de poissons d'eau douce — dans le régime alimentaire. La très faible variation des valeurs enregistrée au sein de la population montre une grande homogénéité, rarement mise en évidence pour cette période, indiquant la consommation de ressources similaires pour l'ensemble des individus étudiés. La comparaison de ces données avec les paramètres biologiques et funéraires dégage toutefois quelques tendances, notamment en fonction de l'âge et du sexe des défunts, ainsi que de la chronologie.

Abstract
The chemical adsorption of oxygen on V2O5 and V2O5 -TiO2 over the temperature range 100–450°C and at pressures between 10−2 and 3 Torr has been studied. Assays have been performed using a volumetric method, the isotherms obtained being in accordance with Langmuir's adsorption model. Isobaric plots at 1.5 Torr of these isotherms exhibit two maxima, at 250 and 400°C, respectively. These maxima have been interpreted in terms of the surface chemisorption of O2− and its diffusion into the bulk solid. The amount adsorbed at the 250°C maximum depends on the sample composition in the following decreasing adsorption order: VT80, VT50, VT10, VT20 and VT0. At the 400°C maximum, the same amount of O2 is adsorbed experimentally by all the TiO2-containing samples, this value being quite different from that corresponding to pure V2O5 (VTO). Possible explanations for this observation are based on (i) the relative magnitudes of the V/Ti surface ratios and (ii) the presence of Ti4+ in V2O5 crystals.

Abstract
Asthma is an increasing pathology with poor compliance. Achievement of control is possible but under intensive treatment. In this setting, fluticasone/salmeterol association delivered by dry powder inhalers is a valuable and proved option. A prospective, parallel, open-label, phase IV, multicentre non-inferiority study was conducted to determine therapeutic similarity between 2 different inhalers: Generic DPI and Diskus®, which both deliver a fluticasone/salmeterol association (CAS 80474-14-2/CAS 89365-50-4). A 103 uncontrolled asthmatic patients were randomly assigned in 2 groups, Generic (G) and Diskus® (D), and received the association for 18 weeks through the appropriate device. They were evaluated according to Asthma Quality of Life Questionnaire and GINA/NIH guidelines. To demonstrate non-inferiority, the estimation of the Relative Risk between the Global Score Rate per group with its 95% confidence interval was calculated and compared against a non-inferiority margin obtained from a previous study. The Global Score Rate was 82% for G Group and 83% for D Group. The RR was 1.0124 (95% CI: 0.847-1.210). The margin set at 0.832 was not reached by the lower 95% CI (z=-2.097; p=0.018) pointing out non-inferiority. The results have demonstrated non-inferiority between groups. Thus, the 2 products are therapeutically similar.

Abstract
The water rat Nectomys squamipes is endemic in Brazil and found naturally infected with Schistosoma mansoni. Helminth communities, their prevalences, intensity of infection and abundance in N. squamipes in an endemic area of schistosomiasis in the state of Rio de Janeiro, Brazil were studied. Four species of nematodes (Physaloptera bispiculata, Syphacia venteli, Hassalstrongylus epsilon and Litomosoides chagasfilhoi) were recovered in 85.3%, two trematodes (Schistosoma mansoni and Echinostoma paraensei) in 38.8% and one cestode species (Raillietina sp.) in 1.7% of rats examined. Rats were infected with up to five helminth species each, and these were highly aggregated in distribution. For H. epsilon and S. venteli, intensities and abundances were higher in adult male and subadult female hosts, respectively. Hassaltrongylus epsilon, P. bispiculata, S. venteli and S. mansoni were classified as dominant species, L. chagasfilhoi and E. paraensei as co-dominant and Raillietina sp. as subordinated. No significant correlation was found in the intensity of infecton between each pair of helminth species. Schistosoma mansoni was not related to any other helminth species according to their infection rates, althougth S. mansoni was well established in the natural helminth comunity of the water rat.

Abstract
A limited number of strains belonging to several genera of Rhizobiaceae are capable of expressing a hydrogenase system that allows partial or full recycling of hydrogen evolved by nitrogenase, thus increasing the energy efficiency of the nitrogen fixation process. This review is focused on the genetics and biotechnology of the hydrogenase system from Rhizobium leguminosarum bv. viciae, a frequent inhabitant of European soils capable of establishing symbiotic association with peas, lentils, vetches and other legumes.

In this work we aim to determine if the secretion can also affect the hemostatic system by causing changes in blood coagulation. Procoagulant and coagulant activities were evaluated on plasma and fibrinogen, respectively. The delay in the thrombin clotting time of fibrinogen previously incubated with the secretion was also determined. Specific hydrolysis of fibrinogen and fibrin incubated with the secretion at different time intervals was shown by electrophoresis on polyacrylamide gel. To determine the structural characteristics of the enzymes degrading fibrinogen and fibrin, secretion were incubated in the presence of 45 mM Na(2)EDTA, 40 mM Benzamidine, and/or 2 mM PMSF before the incubation with fibrinogen or fibrin, respectively. The effect in vivo was investigated in adult male rats injected with different dose of secretion, aliquots of blood were withdrawn at different time intervals, and the fibrinogen concentration was determined. Duvernoy's gland secretion of P. patagoniensis did not clot plasma or fibrinogen. It exhibited a potent fibrinogenolytic activity degrading the Aalpha-chain faster than the Bbeta-chain, whereas gamma-chain was resistant. This latter corresponded with a strong delay in the thrombin clotting time of fibrinogen (4 mg/ml) pre-incubated with the secretion, being 9.53 microg the amount of protein from Duvernoy's gland secretion that increased the thrombin clotting time from 20 to 60 s. In vivo, the loss of rat plasma fibrinogen was proportional to the amount of secretion injected. The secretion also hydrolyzed fibrin degrading the alpha-monomer. Inhibition studies with Na(2)EDTA, Benzamidine, and/or PMSF showed that metalloproteinases and serinoproteinases are the main enzymes responsible for the hydrolyzing activity on fibrinogen and fibrin. All these results demonstrate that Duvernoy's gland secretion of P. patagoniensis possesses enzymes able to hydrolyze plasma components playing a relevant role in the blood coagulation. These hydrolyzing activities and those acting on the wall of blood vessels let the secretion exhibit a high hemorrhagic activity, which may result in permanent sequelae or even cause the death of the victims bitten by this colubrid snake.

Abstract
Colubrid snakes belonging to Philodryas genus, widespread all over South America, bring about lesions (swelling, ecchymosis, transient bleeding from the bite site punctures), that are similar to those produced by Bothrops species (yarará). In the present work we began the characterization of Philodryas patagoniensis venom. We examined if this venom produces hemorrhagic lesions as those observed in victims bitten by Philodryas olfersii. Hemorrhagic, proteolytic and fibrinogenolytic activities were evaluated, and histological observations in samples of gastrocnemius muscle were carried out. Inhibition studies were carried out in metal chelator (ethylenediaminetetraacetic acid) presence. Our results show a small Minimum Hemorrhagic Dose (MHD=0.035 microg) and a high proteolytic activity (143 U/mg), and prove the capacity of this venom to degrade fibrinogen in vitro rendering it unclottable by thrombin, supporting the presence of proteases, principally metalloproteases, in P. patagoniensis venom that are able to alterate the vascular wall and degrade fibrinogen, being both activities responsible of a high hemorrhagic activity.

Abstract
The water rat, Nectomys squamipes, closely involved in schistosomiasis transmission in Brazil, has been found naturally infected simultaneously by Schistosoma mansoni and Echinostoma paraensei. Laboratory experiments were conducted to verify parasitic interaction in concurrent infection. It was replicated four times with a total of 42 water rats and essayed two times with 90 mice pre-infected with E. paraensei. Rodents were divided into three groups in each replication. A wild strain recently isolated from Sumidouro, RJ, and a laboratory strain of S. mansoni from Belo Horizonte (BH) was used. Rats infected with E. paraensei were challenged 4 weeks later with S. mansoni and mice 2 or 6 weeks after the infection with S. mansoni. Necropsy took place 8 weeks following S. mansoni infection. The N. squamipes treatment groups challenged with S. mansoni RJ strain showed a significant decrease (80 and 65%) in the S. mansoni parasite load when compared with their respective control groups. There was a significant change or no change in the hosts challenged with the BH strain. The persistence time of E. paraensei within host was extended in relation to control groups, with a consequent enhancement of the number of recovered worm. An E. paraensei strain-specific influence on S. mansoni parasitism is reported. This paper presents some experimental data about this interaction in N. squamipes and Mus musculus.

Abstract
OBJECTIVES To investigate the spatial distribution, abundance and natural schistosomiasis infection levels in the snail Biomphalaria glabrata, the intermediate host of Schistosoma mansoni in an area of the State of Rio de Janeiro, Brazil. METHODS In the Pamparrão area, Sumidouro county, RJ, Brazil, snail captures were carried out every other month from June 1991 to November 1995. There were 23 collecting sites along the Pamparrão stream and its three tributaries (A, B and C). Captured snails were examined in the laboratory for infection. Data analyses were performed using Spearman coefficient (0.5% significance level) and Qui-square test. RESULTS The abundance of B. glabrata was variable in both time and space. Most of the collection sites showed a negative correlation with rainfall. The tributary B had the highest and most steady infection rates (more than 25% in some sites). There were found significantly more infected snail in the dry season (chi2 = 20.08; p=0.001). CONCLUSIONS B. glabrata population in the Pamparrão valley was negatively influenced by rainfall, especially at the Pamparrão stream. The dry season seems to promote the infection probably due to the lower water volume, increasing the chance of interaction between the intermediate host and the parasite.

Abstract
Primary adrenal insufficiency is a rare disease. Its diagnosis remains a clinical challenge since the signs and symptoms of the disease are insidious in onset and non specific in nature. A case report of Addison's crisis induced by levothyroxine substitution therapy is described. This clinical case is discussed in details with a special emphasis to the published literature regarding the strategy of diagnosis and the specific therapy of primary adrenal insufficiency.

Abstract
Echinostoma paraensei Lie and Basch, 1967 (Echinostomatidae:Platyhelminthes), a 37 collar spine echinostome of the "revolutum group", has been used extensively as a model organism to study the interactions of digenetic trematodes with both their snail and vertebrate hosts. This worm was first isolated from the snail Biomphalaria glabrata from Belo Horizonte (BH isolate), Minas Gerais State, Brazil, by Lie and Basch [J Parasitol (1967) 53:1192-1199]. The natural definitive host for the BH isolate was never determined, and it has been maintained in the laboratory since 1967 in B. glabrata and hamsters. In this study, using light and scanning electron microscopy and molecular analysis, we describe an echinostome recently obtained from its natural vertebrate host, the wild rodent Nectomys squamipes (Rodentia: Sigmodontinae) from Sumidouro, Rio de Janeiro State, Brazil (RJ isolate). This echinostome was also compared to the laboratory-maintained BH isolate of E. paraensei. We observed that adult worms of both BH and RJ isolates could be differentiated from other echinostome species by the relatively small size of the dorsal collar spines relative to lateral and corner collar spines. SEM confirmed the similarity of this morphological character between the two isolates. As additional diagnostic features, the tegumentary spines are scale-like and the region between the genital pore and the acetabulum lacks scales. There is a folded protuberance with a pore just posterior to the genital pore. The tegument of the acetabulum is unspined and radially wrinkled, and there are numerous randomly distributed small, domed, ciliated papillae. The sequences of the internal transcribed spacers of the nuclear rDNA complex of the RJ and BH isolates are identical. Together these shared features provide strong evidence that both isolates are the same and can be referred to as E. paraensei. In conclusion, we have identified, for the first time, one of the natural definitive hosts for E. paraensei, the rodent N. squamipes, and have extended the known geographical distribution of this species to include Sumidouro in Rio de Janeiro State, Brazil.

Abstract
A new isolate of Echinostoma paraensei (Lie & Basch, 1967) was obtained from a natural vertebrate host, the water rat Nectomys squamipes. Relationships with sympatric snails, Biomphalaria glabrata; Physa marmorata and Lymnaea columella, as well as allopatric snails and the definitive hosts N. squamipes, Mus musculus, Rattus norvegicus, Mesocricetus auratus and birds were investigated. E. paraensei developed in all sympatric snail species following exposure to one or five miracidia. P. marmorata showed the highest infection rate (34% and 36%) followed by L. columella (18% and 24%) and B. glabrata (8% and 28%), respectively. Mortality was elevated in the patent period, with L. columella having the highest values. B. glabrata, P. marmorata, and L. columella did not differ in relation to cercarial encystment, and metacercariae from each species were able to infect N. squamipes with similar worm burdens. Recovered adult worms were found in clusters from the first to third sections of the small intestine. Miracidia of E. paraensei hatched after 10 days incubation in darkness in dechlorinated water at 28+/-1 micro C. Miracidia began to hatch 1 h after exposure to incandescent light.

Abstract
A rapid reverse transcription polymerase chain reaction (RT-PCR) and microwell capture hybridisation assay with general specificity for enteroviruses was developed and compared with an improved nested RT-PCR for the detection of enteroviral RNA sequences in endomyocardial tissue from patients with chronic dilated cardiomyopathy. This method could detect as few as 20 genomic RNA copies per 100 mg of heart tissue homogenate and results could be obtained within 8 hours. Of the 55 biopsy specimens aseptically collected from the explanted hearts of 55 patients, 21 (38.2%) were positive by RT-PCR microplate assay, whereas only 19 (34.5%) were positive by nested RT-PCR assay and none were positive by classical cell culture assays. No enterovirus was detectable by RT-PCR or classical cell culture assays in any of the 55 heart biopsy specimens taken from organ donors without any known heart disease. Moreover, the nucleotide sequences of EV nested RT-PCR products showed greatest similarity to group B Coxsackieviruses [CVB3 (n = 12) or CVB5 (n = 3)], but also to group A Coxsackieviruses (CVA21 (n = 1) or CVA9 ( n= 3)]. The described RT-PCR and microwell capture hybridisation assay can be applied to the virological diagnosis of human enteroviral cardiac infections. Moreover our findings suggest that group B and group A Coxsackieviruses can persist in heart tissue from patients with end-stage chronic cardiomyopathy, supporting the hypothesis that these viruses could be implicated in the etiology of idiopathic dilated cardiomyopathy.

Abstract
In the beginning of the XX century, ancylostomiasis was considered a serious public health problem and governments started the first systematic planning for the control of an endemic disease, in large scale. Thereafter, ancylostomiasis was considered a less important subject, because efficient anti-helminthic drugs were introduced, this in combination with the economic development in rich countries, reduced undernourishment and improved housing and sanitary conditions. Consequently, the residual cases of the infection became in general asymptomatic. However, in the third world the problem is still present, and must be considered with realism and managed accordingly. Various suggestions for controling the disease are presented in this paper.

Abstract
To investigate enterovirus replication versus persistence in end-stage cardiac diseases, endomyocardial biopsies from explanted hearts of 70 patients with idiopathic dilated cardiomyopathy (IDCM), 64 patients with chronic coronary disease (CCD), and 45 donors of healthy hearts (controls) were examined by reverse transcriptase-polymerase chain reaction for genomic and antigenomic enterovirus RNA and by VP1 antigen immunohistochemistry. Enterovirus genome was detected in 25 of 70 patients with IDCM and in 21 of 64 patients with CCDs (35.7 vs. 32.8%, respectively; P=.12). Of the 46 patients positive for genomic RNA, only 3 exhibited antigenomic RNA and VP1 antigen that demonstrated active viral replication, whereas 43 had latent infection characterized by the absence of antigenomic RNA associated with or not with VP1 antigen expression. No viral component was detected in control subjects. The findings demonstrate that a small percentage of patients with end-stage chronic cardiac diseases had active enterovirus replication in their myocardium.

Abstract
From March to May 1991, the prevalence of intestinal parasites was detected in 208 children under two-year old, from out patients attending the Public Health Service in Rio de Janeiro. Maternal parasitic infection was simultaneously investigated. Information regarding nurseling's breast-feeding and enteroparasites rates was also recorded. The centrifugal-sedimentation was the method used for stool analysis. Positivity was observed in 12.7% for children and 37.3% for women. Ascaris lumbricoides was the most frequently detected parasite in children under one-year old (4.3%) and mothers (12.7%). The distribution of parasites accordingly to breast-feeding showed a significant statistical difference (p < 0.05) among infants. No exclusively suckled child presented infection. Children whose mothers were infected showed almost two fold risk of infection (1.7). A correlation between enteroparasites and weaned children was observed (r = 0.75). We believe that infected mothers can contribute for parasitic infection of their kids.

Abstract
Schistosomiasis is a health problem in Brazil and the role of rodents in maintaining the schistosome life-cycle requires further clarification. The influence of Schistosoma mansoni on a population of Nectomys squamipes was studied by capture-recapture (1st phase, from June 1991 to November 1995) and removal (2nd phase, from April 1997 to March 1999) studies at Sumidouro, Rio de Janeiro, Brazil. During both phases coproscopic examinations were performed. At the 2nd phase the rodents were perfused and worms were counted. The population dynamics of parasites was studied. During the 1st phase, female reproductive parameters, longevity, recruitment and survivorship rates and migration patterns were studied in relation to schistosome prevalence. Water contamination (source of miracidia), abundance intermediate host and rodent migration were related to prevalence. The N. squamipes population was not obviously influenced by the infection, as shown by the high number of reproductive infected females, high longevity of infected individuals and the absence of a relationship between recruitment or survivorship rates and the intensity of schistosome infection. The data indicate that N. squamipes can increase transmission of S. mansoni in endemic areas and carry it to non-infected areas. Furthermore, this rodent can be used as an indicator of a transmission focus.

Abstract
The expression of recombinant proteins with the Semliki Forest Virus (SFV) system has been scaled up to bioreactor scale. As a model protein for this study the human 5-HT(3) receptor was chosen. The gene for the receptor was subcloned into the SFV expression plasmid pSFV1. Virus production by in vivo packaging and production of the recombinant protein was scaled up, the latter to a reactor volume of 11.5 l. A Vibromix(TM) agitation system was chosen to overcome aggregation problems of BHK cells in suspension. In the process, cells were first grown to a density of 10(6) cells/ml, the medium was then exchanged with fresh medium and the culture was infected with the recombinant virus at an estimated multiplicity of infection of 30. 24 h post infection we measured an expression level of 3 million functional 5-HT(3) receptors per cell. For harvesting, the cells were pelleted by centrifugation. The receptor protein was purified in a single step (Hovius et al., 1998) by exploiting the hexa-His tag at minimal protein loss (51% yield). Experiments to optimise expression resulted in yields up to 8 million receptors per cell, when the pH of a suspension culture was controlled at pH 7.3. Rapid virus generation and protein production, high protein yields as well as successful large scale application have made the SFV expression system attractive to produce large quantities of recombinant protein in a very short time. After optimisation of the expression conditions (in particular by setting the pH at 7.3), yields were increased twofold.

Abstract
BACKGROUND Fine-needle aspiration cytology has proved to be an accurate, cost-effective, and safe technique for diagnosing inflammatory and neoplastic lesions at different body sites. Its applicability in bone pathology, however, has been controversial due to a high percentage of inadequate samples and nonspecific results in the diagnosis of primary bone lesions. In this study, the diagnostic accuracy of the technique and its capacity for diagnosing primary bone lesions were assessed. In addition, the authors analyzed the diagnostic limitations with focus on specimen adequacy. METHODS The authors reviewed 314 consecutive fine-needle aspirations of bone from 308 patients. Direct or cytospin smears from aspirated material were fixed in 95% alcohol and stained by a modified Papanicolaou technique. Ninety-seven smears (31%) initially were considered unsatisfactory and excluded from the study. A diagnosis was rendered in 217 cases (69%), which were classified into 4 categories: primary bone lesions (benign and malignant) (42%), metastatic bone tumors (37%), suspicious for malignancy (5%), and negative (16%). RESULTS The overall accuracy was 95%. Seventy-eight percent of primary bone lesions were correctly diagnosed by cytology. All cases diagnosed as metastatic by cytology were correct. The authors encountered difficulties diagnosing fibro-osseous lesions. Thirteen percent of cases were erroneously diagnosed as "negative" or "inflammatory conditions." On review, the absence of adequate cytologic material was noted in all of them. This sampling error could have been avoided by the presence of an on-site cytopathologist. CONCLUSIONS Fine-needle aspiration of bone is a simple, reliable, and accurate diagnostic technique that can facilitate patient management and preoperative decision-making and/or avoid unnecessary invasive procedures for patients with primary or metastatic bone lesions. However, the radiologist, cytopathologist, and orthopedic surgeon should work together for optimal results. Moreover, a definitive pathologic diagnosis should not be issued if diagnostic material is not adequate and/or clinicoradiologic information is incompatible.

Abstract
The bis(ethylene) Rh species TpMe2Rh(C2H4)2(1*) (TpMe2 = tris(3,5-dimethyl-1-pyrazol-1-yl)hydroborate) has been obtained from [RhCl(C2H4)2]2 and KTpMe2. Complex 1* easily decomposes in solution to give mainly the butadiene species TpMe2Rh(eta74-C4H6). In the solid state its thermal decomposition follows a different course and the allyl TpMe2RhH(syn-C3H4Me) is cleanly obtained as a mixture of exo and endo isomers. The complexes Tp'Rh(C2H4)2 (Tp' = Tp, TpMe2) afford the monosubstituted species Tp'Rh(C2H4)(PR3) upon reaction with PR3 but react differently with L = CO or CNR: the Tp compound gives dinuclear [TpRh]2(mu-L)3 complexes, while, in the case of 1*, TpMe2Rh(C2H4)(L) species are obtained. The ethylene ligand of complexes TpMe2Rh(C2H4)(PR3) is labile, and several peroxo compounds of composition TpMe2Rh(O2)(PR3) have been isolated by their reaction with O2. All the mononuclear Rh(I) complexes are formulated as 18e- trigonal bipyramidal species on the basis of IR and NMR spectroscopic studies. A series of dihydride complexes of Rh(III) of formulation Tp'RhH2(PR3) have been prepared by the hydrogenation of the corresponding ethylene derivatives. Complexes [TpRh]2(mu-CNCy)3, TpMe2Rh(C2H4)(PEt3), and TpMe2Rh(O2)(PEt3) have been further characterized by X-ray diffraction studies.

Abstract
Community-acquired pneumonia from enteric gram-negative bacilli is more common in developing than in industrialized countries. We investigated the nasopharyngeal flora in healthy children from Angola, Brazil and The Netherlands to see whether enteric gram-negative bacilli are more often part of the commensal flora in developing countries. Nasopharyngeal specimens were collected from children aged between 4 months and 5 years in day-care centres and immunization clinics. Children who had received antibiotics or were malnourished were excluded. Brazilian and Angolan children had a higher number of household members than Dutch children (5.5 and 7 vs 3.9 mean number of household members, respectively) (p < 0.0001). Enteric and non-fermentative gram-negative bacilli were much more prevalent in Brazilian (50%) and Angolan (57%) children than in Dutch (4%) children (p < 0.0001). By univariate analysis, carriage of enteric gram-negative bacilli was associated with the number of household members (r = 0.26; p < 0.001). The high carriage rate of enteric gram-negative bacilli in children from Angola and Brazil may explain why enteric gram-negative bacilli are a common cause of pneumonia in developing countries.

Abstract
Haemophilus parainfluenzae was isolated from the bile specimens of 2 patients with acute cholecystitis. The strains were genetically unrelated by the random amplified polymorphic DNA (RAPD). The 2 H. parainfluenzae strains represented 11.7% of all positive bile cultures inoculated in blood culture bottles. The routine inoculation of bile specimens in media able to support growth of Haemophilus species should be considered.

Abstract
In order to investigate the possibility of whether or not the lymphocytes of patients with Alzheimer's Disease (AD) are in an activated state, blood mononuclear cells from 45 AD patients and 45 healthy age matched controls were immunophenotyped by measuring the expression of CD3, CD4, CD7, CD8, CD25, CD28, CD56 and HLA-DR by flow cytometry. Circulating and in-vitro-produced cytokines were also measured by ELISA tests. CD7 and CD8 were significantly decreased in AD patients (48.3% and 18.2%, respectively) when compared to healthy subjects (63.2% and 28.3%, respectively). A significant increase in the CD4, CD25 and CD28 antigen expression was also observed in the AD group (55.3% 24.8% and 65.1%) with respect to healthy subjects (44.5%, 10.3% and 54.3%). In addition there was a significant difference in the extent of apoptosis in lymphocyte culture, as measured by mean fluorescence intensity (MFI) of Fas antigen (CD95) expression on CD4+ T cells in 6 AD patients (MFI = 36% and 43%, by anti-CD3 and hyperthermia mediated-apoptosis, respectively) with respect to 6 healthy individuals (MFI = 24% and 31%, by anti-CD3 and hyperthermia mediated-apoptosis, respectively), as well as in T-cell proliferation assay. A decline of Fas antigen expression on CD8+ subset was observed in the AD group with both stimuli (19% and 28%) comparing to the control group (29% and 39%). No differences were observed on circulating cytokines and spontaneous in vitro production of proinflammatory interleukin 1beta (IL-1beta), Tumor Necrosis Factor-alpha (TNF-alpha), IL-6 and IL-10 cytokines. Lipopolysaccharide (LPS)-stimulated in vitro production of IL-1beta, TNF-alpha, IL-6 and IL-10 measured by a whole blood culture system was significantly higher in AD patients comparing to controls. Furthermore, the observed differences were more evident at late stages of disease. These findings suggest that immunological tests, based on lymphocyte immunophenotyping combined with pro-inflammatory cytokine determinations and measurement of apoptosis in peripheral blood might represent a useful tool to obtain more insight into the pathogenesis of AD and into the level of immune activation which could characterize the pathological state of lymphocytes from individual AD patients.

Abstract
The aim of the present research was to evaluate the potential of Nectomys rattus, the "water rat", to develop Schistosoma mansoni infection. Comparison with N. squamipes was carried out. Both species of rodents were submitted to transcutaneous infection using different infective cercariae loads: 50, 100 or 500. N. rattus showed high susceptibility to S. mansoni, with an infection rate of 71%. Rodents were able to excrete viable eggs of S. mansoni in the faeces during all infection period. For both species, the small intestine, followed by the liver and the large intestine, presented the highest concentration of eggs among the surveyed organs. Infection caused no animal death. Moreover, N. rattus accomplished the parasite's life cycle, by infecting the snails Biomphalaria glabrata and later Mus musculus. These evidences indicate that both N. rattus, as for N. squamipes are potential reservoirs for schistosomiasis in Brazil. Considering the fact that N. rattus and N. squamipes exist in the same natural ecosystems of S. mansoni, we suggest that these rodents must be regarded as influential factors in epidemiology surveys.

Abstract
The Azotobacter vinelandii cytochrome c5 gene (termed cycB) was cloned and sequenced. Mutants in this c-type cytochrome as well as cytochrome c4 mutants (mutations in cycA) and double mutants in both of the c-type respiratory pathways were characterized. Spectral and heme staining experiments on membranes from the mutants were consistent with the anticipated characteristics of all the gene-directed mutants. Membranes of the individual cytochrome c4 or c5 mutants had normal respiratory rates with physiological substrates but respiration significantly lower than the wild-type rate with ascorbate-N,N,N',N',-tetramethyl-p-phenylenediamine (TMPD) as a reductant. The growth rates of the individual cytochrome c4 or c5 mutants were not markedly different from that of the wild-type strain, but the cycA cycB double-mutant strain was noticeably growth retarded at and below 7.5% O2 on both N-containing and N-free media. The double-mutant strain was unable to grow on agar plates at O2 tensions of 2.5% or less on N-free medium. As the wild-type growth was unaffected by varying the O2 tension, the results indicate that the role of the cytochrome c-dependent pathways is to provide respiration at intermediate (5 to 10%) and low (below 5%) O2 tensions. The two c-type cytochrome genes are transcriptionally up-regulated with N2 fixation; N starvation caused 2.8-fold and 7- to 10-fold increases in the promoter activities of cycA and cycB, respectively, but these activities were affected little by the O2 level supplied to the cultures.

Abstract
Rhizobium leguminosarum bv. viciae expresses an uptake hydrogenase in symbiosis with peas (Pisum sativum) but, unlike all other characterized hydrogen-oxidizing bacteria, cannot express it in free-living conditions. The hydrogenase-specific transcriptional activator gene hoxA described in other species was shown to have been inactivated in R. leguminosarum by accumulation of frameshift and deletion mutations. Symbiotic transcription of hydrogenase structural genes hupSL originates from a -24/-12 type promoter (hupSp). A regulatory region located in the -173 to -88 region was essential for promoter activity in R. leguminosarum. Activation of hupSp was observed in Klebsiella pneumoniae and Escherichia coli cells expressing the K. pneumoniae nitrogen fixation regulator NifA, and in E. coli cells expressing R. meliloti NifA. This activation required direct interaction of NifA with the essential -173 to -88 regulatory region. However, no sequences resembling known NifA-binding sites were found in or around this region. NifA-dependent activation was also observed in R. etli bean bacteroids. NifA-dependent hupSp activity in heterologous hosts was also absolutely dependent on the RpoN sigma-factor and on integration host factor. Proteins immunologically related to integration host factor were identified in R. leguminosarum. The data suggest that hupSp is structurally and functionally similar to nitrogen fixation promoters. The requirement to coordinate nitrogenase-dependent H2 production and H2 oxidation in nodules might be the reason for the loss of HoxA in R. leguminosarum and the concomitant NifA control of hup gene expression. This evolutionary acquired control would ensure regulated synthesis of uptake hydrogenase in the most common H2-rich environment for rhizobia, the legume nodule.

Abstract
The water rat, Nectomys squamipes, is reported as a natural host of Schistosoma mansoni in Brazil. This paper presents some reproductive, growth and developmental data, and laboratory management of a breeding programme for N. squamipes. The colony was derived from animals captured at Sumidouro, Rio de Janeiro state. The animals' diploid number was 56, conception rate was 66.7% and gestation period was 30 days. Litter size ranged from 1 to 6, with a mean of 4.1 (SD +/- 1.2) and a mode of 4 and 5. Sex ratio at birth and at weaning was not significantly different from the expected ratio of 1:1. There were no significant differences between mean body weights at birth for males and females. The minimum age for weaning was between 20-25 days. The growth curves of body weight, head-body length and tail length, for both sexes, comprise at least three linear segments representing different phases of approximately constant growth rates. Facilities for colony maintenance and its potential for use as experimental model are reported.

Abstract
Plasmid pAL618 contains the genetic determinants for H2 uptake (hup) from Rhizobium leguminosarum bv. viciae, including a cluster of 17 genes named hupSLCDEFGHIJK-hypABFCDE. A 1.7-kb segment of insert DNA located downstream of hypE has now been sequenced, thus completing the sequence of the 20441-bp insert DNA in plasmid pAL618. An open reading frame (designated hypX) encoding a protein with a calculated M(r) of 62300 that exhibits extensive sequence similarity with HoxX from Alcaligenes eutrophus (52% identity) and Bradyrhizobium japonicum (57% identity) was identified 10 bp downstream of hypE. Nodule bacteroids produced by hypX mutants in pea (Pisum sativum L.) plants grown at optimal nickel concentrations (100 microM) for hydrogenase expression, exhibited less than 5% of the wild-type levels of hydrogenase activity. These bacteroids contained wild-type levels of mRNA from hydrogenase structural genes (hupSL) but accumulated large amounts of the immature form of HupL protein. The Hup-deficient mutants were complemented for normal hydrogenase activity and nickel-dependent maturation of HupL by a hypX gene provided in trans. From expression analysis of hypX-lacZ fusion genes, it appears that hypX gene is transcribed from the FnrN-dependent hyp promoter, thus placing hypX in the hyp operon (hypBFCDEX). Comparisons of the HypX/HoxX sequences with those in databases provided unexpected insights into their function in hydrogenase synthesis. Similarities were restricted to two distinct regions in the HypX/HoxX sequences. Region I, corresponding to a sequence conserved in N10-formyltetrahydrofolate-dependent enzymes involved in transferring one-carbon units (C1), was located in the N-terminal half of the protein, whereas region II, corresponding to a sequence conserved in enzymes of the enoyl-CoA hydratase/isomerase family, was located in the C-terminal half. These similarities strongly suggest that HypX/HoxX have dual functions: binding of the C1 donor N10-formyltetrahydrofolate and transfer of the C1 to an unknown substrate, and catalysis of a reaction involving polarization of the C = O bond of an X-CO-SCoA substrate. These results also suggest the involvement of a small organic molecule, possibly synthesized with the participation of an X-CO-SCoA precursor and of formyl groups, in the synthesis of the metal-containing active centre of hydrogenase.

Abstract
The authors presented a detailed summary of the geographical distribution, clinical and pathological aspects of human pulmonary dirofilariasis. Although benign, this zoonosis, of which Dirofilaria immitis is the major etiological agent, represents a medical problem since it produces symptoms which may be confused with neoplasia and thus may subject patients to unnecessary thoracic surgery. Of 229 cases cited in the literature, only 17 were reported in Brazil, despite the existence of highly favorable conditions for the transmission of this infection in man. Thus it may well be that this parasitic infection remains underdiagnosed. Finally, the importance of a differential diagnosis between dirofilariasis and pulmonary neoplasia is emphasized in cases where there is a solitary subpleural nodule ("coin lesion") present. In addition, the development and improvement of modern immunological diagnostic techniques are essential to distinguish this benign disease from other pathological conditions and thus avoid unnecessary surgery. These techniques may reveal the true prevalence of this parasitic infection in our environment.
