Abstract
The composition of macro endoparasites associated with the lizard Norops fuscoauratus (Squamata) was analysed in two localities in the Atlantic Forest on the northeast of Brazil between December 2012 and July 2015. 74 specimens of N. fuscoauratus were examined and five species of helminths were reported, being: (a) for the population of Pernambuco: Cystacanth (Prevalence=37.5%), Physaloptera retusa Rudolphi, 1819 (Prevalence=4.16%), larva of flatworm (Prevalence=2.08%), Rhabdias sp. (Prevalence=2.08%) and Strongyluris oscari Travassos, 1923 (Prevalence=2.08%), and (b) of Alagoas: S. oscari (Prevalence=17.85%) and Rhabdias sp. (Prevalence=3.57%). The differences in the composition of endoparasites in the two populations are attributed to individualities of environments occupied by the lizards. The collection period does not influence the abundance of parasites, but when associated with sex, there was a positive correlation with the abundance of helminths, with more females than males being infected with parasites in the rainy season.

Abstract
We investigated the infection by pulmonary parasites in the lizard Ameiva ameiva (Teiidae) inhabiting the Environmental Protection Area of Araripe (APA-Araripe). A total of 45 specimens were collected in three areas between the cities of Várzea Alegre and Barbalha. A Pentastomid species (Raillietiella mottae) was parasitizing (nine specimens) a male of A. ameiva with a prevalence of 2.22% considering all lizards collected in the region and prevalence of 50% considering only rainforest environment. The Pentastomids infection rates shown in this study are similar to data found for infections of other insectivorous lizards. Raillietiella mottae is considered a generalist parasite, which uses insects as intermediate hosts. The results of this study represent the first record of a Pentastomid infecting this species of lizard in South America.

Abstract
Abstract Nematodes were analyzed in Iguana iguana, a large lizard Iguanidae that is widely distributed throughout the Americas. The aims of the study were investigate the helminths associated with the lizard, I. iguana in semi-arid areas of northeastern Brazil and analyze the parasitological indices (prevalence, and mean intensity of infection). A total of 18 specimens of I. iguana were examined (8 males and 10 females). The overall prevalence of infection was 66.6% (12/18), while in males, it was 75% (6/8) and in females, 60% (6/10). Iguana iguana was identified as a new host for Physaloptera sp., Atractis sp., Piratuba sp. and Subulura sp. This registered contributes to the knowledge of helminth diversity associated with this host.

Abstract
The lizard Salvator merianae is a widely distributed species in South America, occurring from southern Amazonia to the eastern Andes and northern Patagonia. Studies on the parasitic fauna of this lizard have revealed that it is a host for helminths in various Brazilian biomes. The present work provides new parasitological data on the gastrointestinal nematodes associated with the lizard S. merianae. Sixteen specimens were analyzed from nine different locations in a semi-arid region in northeastern Brazil. Five species of nematodes were identified. Oswaldofilaria petersi was first recorded as a parasite of the S. merianae, thus increasing the knowledge of the fauna of parasites that infect large Neotropical lizards.

Abstract
We present data on nematode infracommunity of the arboreal lizard Polycrhus acutirostris in the semiarid Caatinga biome, northeastern Brazil. Twenty- twolizard specimens collected in the municipality of Várzea Alegre in Ceará State and in the municipality of Exu in Pernambuco State were analyzed. Two species of nematodes were found, an Oxyuridae, Gynaecometra bahiensis, which had a mean intensity of infection 23.5 ± 5.8 (prevalence 22%) and a Physalopteridae, Physaloptera retusa which had infection intensity of 21 (prevalence 9%). There were no significant differences between the parasitism rates of male or female lizards. Polychrus acutirostris demonstrated low richness of nematode parasites, but high levels of infection with G. bahiensis. Polychrus acutirostrisis reported here as a new host for P. retusa.

Abstract
CONTEXT Ethnozoological studies have shown that Spilotes pullatus Linn. (Colubridae: Ophidia), is associated with medicinal and magic-religious uses in Brazil. OBJECTIVES This study was designed to determine the chemical composition of the oil extracted from the body fat of S. pullatus and to test its antimicrobial properties, alone and in association with aminoglycosides, against fungi and bacterial strains in concentrations ranging between 1024 and 0.5 µg/mL. MATERIAL AND METHODS The snakes were collected in the Chapada do Araripe, county of Crato, Ceará State, Brazil. The oil was extracted in a Soxhlet apparatus using hexane. The methyl esters of the fatty acids present in the samples were identified using GC-MS. The antimicrobial and drug modulatory activities of oil were tested by microdilution against fungal and bacterial strains. RESULTS The chemical composition of the fixed oils of S. pullatus identified 10 constituents representing 94.97% of the total sample. The percentages of saturated and unsaturated fatty acids were 33.59 and 61.38%, respectively, with the most abundant components being elaidic (37.26%). The oil did not demonstrate any antimicrobial or antifungal activity when tested alone, presenting MIC values ≥ 1024 µg/mL. However, when associated with antibiotics, it demonstrated synergistic effects with gentamicin against all the bacterial lineages assayed, and antagonistic effects with amikacin and neomycin against strains of Escherichia coli. CONCLUSIONS Oil extracted from the body fat of S. pullatus did not demonstrate any inhibitory effects on bacterial or fungal activities, but was effective in modulating the effects of certain antibiotics.

Abstract
AIM Evaluate technologically relevant properties from bacteriocin-producing strains to use as starter/adjunct cultures in cheese making. METHODS AND RESULTS Eight isolates obtained from Pico cheese produced in Azores (Portugal) were found to produce bacteriocins against Listeria monocytogenes and three isolates against Clostridium perfringens. They were identified as Lactococcus lactis and Enterococcus faecalis and submitted to technological tests: growth at different conditions of temperature and salt, acid production, proteolysis, lipolysis, coexistence, enzymatic profile and autolytic capacity. Safety evaluation was performed by evaluating haemolytic, gelatinase and DNase activity, resistance to antibiotics and the presence of virulence genes. Some isolates presented good technological features such as high autolytic activity, acid and diacetyl production. Lactococcus lactis was negative for all virulence genes tested and inhibit the growth of all Lactic acid bacteria (LAB) isolates. Enterococci were positive for the presence of some virulence genes, but none of the isolates were classified as resistant to important antibiotics. CONCLUSIONS The bacteriocin-producing Lc. lactis present good potential for application in food as adjunct culture in cheese production. The study also reveals good technological features for some Enterococcus isolates. SIGNIFICANCE AND IMPACT OF THE STUDY Bacteriocin-producing strains presented important technological properties to be exploited as new adjunct culture for the dairy industry, influencing flavour development and improve safety.

Abstract
The parameters of infection by lung parasites from two sympatric lizards, Mabuya arajara and Anolis brasiliensis, from the Atlantic Rainforest of the lower slope of Chapada do Araripe in Northeastern Brazil were analyzed between September, 2009 and July, 2010. A total of 202 lizards were collected. 125 specimens were from Mabuya arajara and 77 from Anolis brasiliensis. M. arajara was infected by the pentastomid Raillietiella mottae while A. brasiliensis was infected by the nematode Rhabdias sp., with an overall prevalence of 1.6% and 28.6%, respectively. The mean intensity of infection by Rhabdias sp. was 3.63 ± 2.58 (range 1-15). The body size and sex of lizards did not influence the intensity of infection by Rhabdias sp. The overall prevalence was also not different between males and females hosts in A. brasiliensis. Both Anolis brasiliensis and Mabuya arajara represent a new host to Rhabdias sp. and Raillietiella mottae, respectively.

Abstract
Parasitism of the lizard Tropidurus hispidus by Geckobiella sp. and by larvae of Eutrombicula alfreddugesi was examined in a mountainous area in Chapada do Araripe (07° 16' S and 39° 26' W), southern Ceará State, Brazil. Of the 56 lizards collected (26 females, 27 males, and 3 juveniles), 40 (total prevalence of 71.42%) were infested by mites. Mite-pockets were the sites most heavily infested by E. alfreddugesi larvae, while Geckobiella sp. was found uniformly distributed under scales over the host's entire body. The female specimens of T. hispidus parasitised by E. alfreddugesi had an average infestation rate of 8.57 ± 3.62, 1-27, while the males had an average infestation rate of 11.90 ± 2.63, 1-25. The female specimens parasitised by Geckobiella sp. had an average infestation rate of 5.91 ± 2.28, 1-25, while the males had an average infestation rate of 5.43 ± 1.52, 1-23. Seven specimens were also infested by eggs and immature forms of unidentified mites (average 2.28 ± 0.89, 1-7). There were no significant differences between the total prevalence of mites on adult male (70.4%) and adult female (65.4%) lizards. The body sizes of the hosts did not influence their infestation rates. The average infestation intensity by E. alfreddugesi (10.2 ± 8.7) was significantly greater than the average infestation intensity by Geckobiella sp. (5.9 ± 6.8). T. hispidus is the new host record to Geckobiella mites.

Abstract
Raillietiella gigliolii is a Neotropical pentastomid parasite found in Amphisbaena alba. Collections were made in northeastern Brazil in a remnant area of Atlantic Forest (07 masculine 10' S and 35 masculine 05' W) in the municipality of Cruz do Espírito Santo, Paraíba State, and in a Humid Forest area (07 masculine 16' S and 39 masculine 26' W) on the slopes of the Chapada do Araripe Mountains, municipality of Crato, Ceará state, Brazil. Nine specimens of A. alba and 12 of A. vermicularis were collected to gather basic ecological data (prevalence and mean intensity of infection) concerning these parasites. Raillietiella gigliolii was found infecting the lungs of both species. The prevalence for A. alba was 55.5% (5/9), with a mean intensity of infection of 5.0 +/- 2.53 and amplitudes of 1-13. A. vermicularis demonstrated prevalence of 50%, with a mean intensity of infection of 5.3 +/- 2.1 and amplitudes of 1-14. This represents the first record of R. gigliolii as a parasite of A. vermicularis. Our results suggest that R. gigliolii is a generalist parasite species and that an overlapping diet is the determinant factor in the sharing of its final hosts.

Abstract
Pulmonary parasitism by pentastomids was examined in two lizard species inhabiting an area of restinga vegetation (coastal sand dunes) situated in the municipality of Mataraca (6 degrees 29' S and 34 degrees 56' W), on the extreme northern coast of Paraíba State, Brazil. A total of 123 lizards were collected, being 75 specimens of Micrablepharus maximiliani (Gymnophtalmidae) and 48 specimens of Cnemidophorus ocellifer (Teiidae). Only a single species of Pentastomida (Raillietiella mottae) was found parasitizing three females M. maximiliani, with a prevalence of 4% and an average infection intensity of 2.3 +/- 1.3 (range 1-5). The infection rate by pentastomids encountered in the present study was similar to that seen with other species of restinga lizards. Raillietiella mottae is a generalist parasite species that is probably transmitted by common and widely distributed insects making up part of the diet of many insectivorous lizard species from northeastern Brazil.

Abstract
OBJECTIVES To evaluate operative time, blood loss and inflammatory response in patients submitted to hysterectomy. METHODS Sixty patients referred for hysterectomy were prospectively randomized to total abdominal hysterectomy (n=20), vaginal hysterectomy (n=20), or laparoscopic hysterectomy (n=20). The operative time, blood loss (variation in erythrocyte and hemoglobin) and inflammatory answer (CRP and interleukin-6 dosages) were compared by using Kruskal-Wallis, Dunn non-parametric test and variance analysis with repeated measurements. RESULTS Operative time was shorter for vaginal hysterectomy, and there was no significant difference between total abdominal hysterectomy and laparoscopic hysterectomy. Reduction in erythrocyte and hemoglobin was more noticeable after vaginal hysterectomy, followed by total abdominal hysterectomy and laparoscopic hysterectomy. CRP levels increased steadily from vaginal hysterectomy to laparoscopic hysterectomy and then to total abdominal hysterectomy. The increase in interleukin-6 was substantially higher in total abdominal hysterectomy, whereas no difference was noted between vaginal and laparoscopic hysterectomy. CONCLUSIONS Vaginal hysterectomy presents superior results in terms of operative time and inflammatory response when compared with total abdominal and laparoscopic hysterectomy and it should be the first option for hysterectomy. Laparoscopic hysterectomy should be considered when the vaginal approach is unfeasible, showing clear advantages over abdominal hysterectomy.

Abstract
OBJECTIVES To evaluate the pregnancy outcome after laparoscopic tubal anastomosis. METHODS From December 1998 to December 2001, 26 patients with bilateral tubal ligation who underwent laparoscopic tubal anastomosis were prospectively evaluated. Patients' age varied from 28 to 37 years. RESULTS Laparoscopic tubal reversal was performed in 23 patients. Bilateral reversal was possible in all but two patients. The operation time ranged from 95 to 155 min and all patients were discharged in the following morning after surgery. After 3 months, tubal patency was confirmed in 15 patients (15/23). Pregnancy rate was 56.5% (13/23), without ectopic pregnancies. The average time from tubal reversal and pregnancy was 6 months. CONCLUSIONS In selected cases, laparoscopic tubal reversal can be offered to patients who had been submitted to tubal sterilization and desire new pregnancies. Patient selection as well as meticulous surgical technique are key factors in achieving satisfactory pregnancy rates.

Abstract
This work presents a study of the partitioning of a plasmid vector containing the cystic fibrosis gene in polyethylene glycol (PEG)/salt (K2HPO4) aqueous two-phase systems (ATPS). The plasmid was extracted from neutralized alkaline lysates using PEG with molecular weights varying from 200 to 8000. The effects of the lysate mass loaded to the ATPS (20, 40, and 60% w/w) and of the plasmid concentration in the lysate were evaluated. The performance of the process was determined by qualitative and quantitative assays, carefully established to overcome the strong interference of impurities (protein, genomic DNA, RNA), salt, and PEG. Plasmid DNA partitioned to the top phase when PEG molecular weight was lower than 400. The bottom phase was preferred when higher PEG molecular weights were used. Aqueous two-phase systems with PEG 300, 600, and 1000 were chosen for further studies on the basis of plasmid and RNA agarose gel analysis and protein quantitation. The recovery yields were found to be proportional to the plasmid concentration in the lysate. The best yields (>67%) were obtained with PEG 1000. These systems (with 40 and 60% w/w of lysate load) were able to separate the plasmid from proteins and genomic DNA, but copartitioning of RNA with the plasmid was observed. Aqueous two-phase systems with PEG 300 concentrated both plasmid and proteins in the top phase. The best system for plasmid purification used PEG 600 with a 40% (w/w) lysate load. In this system, RNA was found mostly in the interphase, proteins were not detected in the plasmid bottom phase and genomic DNA was reduced 7.5-fold.

Abstract
BACKGROUND The basic and applied research efforts devoted to the development of DNA vaccines must be accompanied by manufacturing processes capable of being scaled up and delivering a clinical-grade product. This work describes a rapid process of this kind, based on hydrophobic interaction chromatography (HIC) for the production of milligram quantities of an experimental DNA rabies vaccine. Its properties and protective activity are tested in comparison with the same plasmid DNA purified with a commercial kit. METHODS The experimental DNA vaccine encoding the rabies virus glycoprotein was amplified in vivo in Escherichia coli. The plasmid was isolated by alkaline lysis, pre-purified and concentrated by isopropanol and (NH4)2SO4 precipitation, and purified by HIC and dialysis. Product quality was controlled by using high-performance liquid chromatography (HPLC), Southern slot blotting, agarose gel electrophoresis, the kinetic-QCL Limulus amoebocyte lysate assay, and protein assays. The expression of the rabies virus glycoprotein was tested in vitro in neuroblastoma cells. The production of rabies-virus-neutralising antibodies and the protection against an intracerebral virus challenge were tested in mice. RESULTS One hundred and forty-two milligrams of the plasmid, with an HPLC purity greater than 99% were obtained from 4.5 l medium. Control analysis showed that the vaccine conforms to specifications in terms of impurities (endotoxins, genomic DNA, RNA, proteins). Furthermore, the final experimental vaccine induces rabies-virus-neutralising antibodies and protects mice against a rabies virus challenge. CONCLUSIONS This study demonstrates that the method developed for the purification of milligram amounts of plasmid delivers an endotoxin-free, experimental rabies DNA vaccine, with protective activity similar to that obtained with the vaccine purified using a commercial kit.

Abstract
The surgical treatment of patients with dysfunctional uterine bleeding (DUB) is discussed in this chapter, including indications, techniques and complications. Hysterectomy is the definitive treatment for DUB; in most studies it has a higher rate of patient satisfaction than does hysteroscopic endometrial ablation. The vaginal or laparoscopic approach should be selected in this group of patients with small uteri, while laparotomy is seldom indicated. In general, the indications for vaginal hysterectomy and endometrial ablation differ from those of laparoscopic hysterectomy. Ablation and vaginal hysterectomy are done for hypermenorrhoea, while laparoscopic hysterectomy is best when pathology is present, usually adhesions, endometriosis or fibroids.

Abstract
OBJECTIVE To assess outcomes and pregnancy-related complications after laparoscopic myomectomy in infertile patients. DESIGN Retrospective analysis. SETTING Tertiary care advanced laparoscopic center. PATIENT(S) Twenty-eight infertile patients with at least one uterine leiomyoma of >5 cm in diameter. INTERVENTION(S) Laparoscopic myomectomy. MAIN OUTCOME MEASURE(S) Occurrence of pregnancy, delivery rate, and pregnancy-related complications. RESULT(S) The average size of the myomas removed was 6 cm (range, 4-13.3 cm). None of the procedures were converted to laparotomy. The postoperative rate of intrauterine pregnancy was 64.3% (n = 18), including 1 of 2 patients who underwent concomitant hysteroscopic myomectomy. Four patients had spontaneous abortions and 14 delivered viable term neonates. Six women had a vaginal delivery without complications and 8 had a cesarean section. No antepartum or intrapartum complications were reported. CONCLUSION(S) Laparoscopic myomectomy can be offered to patients who want to have children and who refuse to undergo an abdominal myomectomy. Patient selection as well as meticulous surgical technique are the key factors in achieving a successful outcome.

Abstract
BACKGROUND The majority of laparoscopic complications occur at the time of Veress needle and trocar insertion. Although not very frequent, they increase the morbidity and mortality of both diagnostic and operative laparoscopic procedures. Alternative techniques of trocar insertion have been described but have not completely eliminated the risk of injury. TECHNIQUE After Veress needle insertion and establishment of pneumoperitoneum to 25 to 30 mm Hg, insertion of a short trocar is performed in the deepest part of the umbilicus without elevation of the anterior abdominal wall. The result is a parietal peritoneal puncture directly beneath the umbilicus. The high-pressure setting used during initial insertion of the trocar is lowered as soon as safe abdominal entry is documented. EXPERIENCE The trocar insertion technique described above was performed in 3041 procedures. No vascular injury occurred. There were two bowel perforations. No complications related to the increased intra-abdominal pressure were observed. CONCLUSION The high-pressure abdominal entry technique has the advantage of reducing intra-abdominal trocar-related injuries without requiring additional instrumentation or additional training.

Abstract
The nature and the magnitude of variability in 13 wing morphological characters of Musca domestica and the influence of environmental factors that could contribute to the occurrence of these variations were studied. Size and sexual dimorphism accounted for most of the total variation (83.7%). Variability caused by shape, which has a large genetic background, represents only 6.5% of the total variability. Males are usually smaller than females and both vary in a similar way throughout the year. Larval rearing density explains 93% of size changes.

Abstract
OBJECTIVE The authors undertook a review of the literature on the dexamethasone suppression test (DST) as a predictor of course and outcome in major depression, to illustrate clinical and pathophysiological implications of studying the relation between biological measures and course of illness in psychiatry. METHOD In computerized searches and cross-references, 144 articles were found that related DST results to prediction of treatment response or outcome. Meta-analysis was performed on pooled data from all of the studies and separately on data from selected studies that had used stricter methodology. RESULTS 1) Baseline DST status did not predict response to antidepressant treatment or outcome after hospital discharge. 2) Non-suppression of cortisol on the baseline DST predicted poorer response to placebo. 3) Persistent nonsuppression of cortisol on the DST after treatment was associated with high risk of early relapse and poor outcome after discharge. CONCLUSIONS Baseline DST results may be devoid of prognostic value, but posttreatment nonsuppression of cortisol on the DST is strongly associated with poor outcome. Persistent nonsuppression may reflect a partially treated index episode or identify sicker patients who are unresponsive to treatment. The findings reiterate the importance of studying biological measures in relation to multiple validators of psychiatric illness beyond cross-sectional diagnosis.

Abstract
The present study was conducted to establish the degree of interrelationship between neuropsychological functioning in the acute phase of the schizophrenic illness, clinical measures of treatment response (positive and negative symptoms), and 1-year outcome. Nineteen SADS/RDC schizophrenic inpatients were clinically rated during a 2-week drug washout period and again following 4 weeks of neuroleptic treatment. The findings revealed that reduced attentional ability in the baseline phase significantly predicted the presence of higher residual negative symptoms following 4 weeks of treatment, while neurocognitive status was unrelated to positive symptom response. With respect to prediction of the 1-year outcome, poor functional status of this schizophrenic population was significantly associated with the presence of baseline memory dysfunction.

Abstract
To assess clinical predictors of 1-year outcome in schizophrenia, 63 patients were studied prospectively. Persistent negative and total symptoms after 4 weeks of neuroleptic treatment accounted for 62% of the variance of 1-year outcome, whereas baseline measures showed no relationship to outcome. Thus, 1-year outcome in schizophrenia can be reasonably predicted on the basis of symptoms persisting after 4 weeks of treatment.
