Abstract
AIM Determining gastrointestinal parasites' frequency in non-human primates (NHPs) and handlers in different Brazilian institutions, and associate it with management information. METHODS Different institutions in São Paulo (A), Brasília (B), Rio de Janeiro (C), Pará (D) and Santa Catarina (E) were included in the study. Fecal samples were processed by using coproparasitological techniques; information about NHP handling and professionals' routine were collected through the use of questionnaires. RESULTS In total, 33.1% of 511 NHP samples were positive for parasites; the Entamoebidae Group and Strongyloides sp.-compatible eggs were the most detected protozoa and helminths, respectively. The Entamoebidae Group was mainly diagnosed in Alouatta from Institutions E and D, and was also the only parasite detected in handlers. Strongyloides-compatible eggs were mostly evident in fecal samples collected from Cebidae from Institutions B and D. Some risk factors associated with parasite infection were a high number of animals in the same enclosure and their use for research protocol purposes, whereas quarantine, a post-infection vacant period in enclosures and antiparasitic supply were categorized as protective factors against these agents' infection. CONCLUSIONS Parasites showing different transmission routes but concomitantly circulating in NHP institutions located in different Brazilian regions were identified in the current study, with an emphasis on those presenting zoonotic potential.

Abstract
L-Carnitine, a natural antioxidant found in mammals, plays a crucial role in the transport of long-chain fatty acids across the inner mitochondrial membrane. It is used as a nutritional supplement by professional athletes, improving performance and post-exercise recovery. Additionally, its therapeutic applications, including those in male infertility, have been investigated, as it may act as a defense mechanism against the excessive production of reactive oxygen species (ROS) in the testis, a process that can lead to sperm damage. This effect is achieved by enhancing the expression and activity of enzymes with antioxidant properties. Nevertheless, the mechanisms underlying the benefits of L-Carnitine remain unknown. This review aims to consolidate the current knowledge about the potential benefits of L-Carnitine and its role in male (in)fertility. Considering in vitro studies with Sertoli cells, pre-clinical studies, and investigations involving infertile men, a comprehensive understanding of the effects of L-Carnitine has been established. In vitro studies suggest that L-Carnitine has a direct influence on somatic Sertoli cells, improving the development of germ cells. Overall, evidence supports that L-Carnitine can positively impact male fertility, even at a relatively low dose of 2 g/day. This supplementation enhances sperm parameters, regulates hormone levels, reduces ROS levels, and subsequently improves fertility rates. However, further research is needed to elucidate the underlying mechanisms and establish optimal doses. In conclusion, the role of L-Carnitine in the field of male reproductive health is highlighted, with the potential to improve sperm quality and fertility.

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
This study aimed to examine the acute effects of cryotherapy on knee position sense and to determine the time period necessary to normalize joint position sense when exercising after cryotherapy. 12 subjects visited the laboratory twice, once for cryotherapy followed by 30 min of exercise on a cycloergometer and once for cryotherapy followed by 30 min of rest. Sessions were randomly determined and separated by 48 h. Cryotherapy was applied in the form of ice bag, filled with 1 kg of crushed ice, for 20 min. Knee position sense was measured at baseline, after cryotherapy and every 5 min after cryotherapy removal until a total of 30 min. The main effect of cryotherapy was significant showing an increase in absolute (F7,154=43.76, p<0.001) and relative (F7,154=7.97, p<0.001) errors after cryotherapy. The intervention after cryotherapy (rest vs. exercise) revealed a significant main effect only for absolute error (F7,154=4.05, p<0.001), i.e., when subjects exercised after cryotherapy, the proprioceptive acuity reached the baseline values faster (10 min vs. 15 min). Our results indicated that the deleterious effect of cryotherapy on proprioception is mitigated by low intensity exercise, being the time necessary to normalize knee position sense reduced from 15 to 10 min.

Abstract
Objetivou-se analisar os efeitos dos níveis de energia metabolizável e da idade de abate sobre o desempenho zootécnico, rendimento de carcaça e cortes de frangos da linhagem Caipira Francês Barré. O experimento foi conduzido em galpão experimental localizado em Parauapebas, PA. Foram utilizados 192 pintos, mistos, de 1 dia, criados em sistema intensivo. O delineamento experimental utilizado foi inteiramente casualizado, com 3 tratamentos. Cada tratamento foi formado de 4 repetições, sendo a unidade experimental 1 box de 16 aves. Os tratamentos foram definidos de acordo com os níveis de energia metabolizável das rações inicial (1 a 28 dias) e final (29 a 90 dias), respectivamente: T1 - 3000 e 3100 kcal de EM/kg; T2 - 3100 e 3200 kcal de EM/kg; T3 - 3200 e 3300 kcal de EM/kg. As variáveis estudadas foram peso inicial, peso final, consumo de ração e conversão alimentar, proteína bruta consumida, proteína metabolizada consumida, eficiência energética e eficiência protéica. As características de carcaças das aves, analisadas com 77, 84 e 91 dias de idade, foram o rendimento de carcaça, peito, coxas, sobrecoxas, asa, dorso, asas, pés, cabeça e pescoço. A análise estatística dos dados foi realizada utilizando o procedimento ANOVA, para um modelo inteiramente casualizado, com o programa Sistema para análise estatística e genética (SAEG, 2007). As diferenças entre as médias das variáveis estudadas foram realizadas pelo Teste de Tukey a um nível de 5%. Os níveis de energia nas dietas não interferiram no desempenho zootécnico e no rendimento de carcaça, peito, coxas, sobrecoxas, asas, pés e cabeça + pescoço das aves. O nível de 3200 kcal de EM/kg proporcionou melhor rendimento de dorso. A proteína bruta e a energia metabolizada consumida pelas aves melhoraram com o incremento energético da ração, durante a fase de engorda. A idade de abate não influenciou no rendimento de carcaça, entretanto as aves abatidas aos 90 dias de idade apresentaram maior rendimento de peito.

Abstract
Increases in the maritime transportation of Hazardous and Noxious Substances (HNS), alongside the need for an effective response to HNS spills have led environmental managers and the scientific community to focus attention on HNS spill preparedness and responsiveness. In the context of the ARCOPOL project, a weight-of-evidence approach was developed aimed at prioritizing HNS that pose major environmental risks to European waters. This approach takes into consideration the occurrence probability of HNS spills in European Atlantic waters and the severity of exposure associated with their physico-chemical properties and toxicity to marine organisms. Additionally, a screening analysis of the toxicological information available for the prioritization of HNS was performed. Here we discuss the need for a prioritization methodology to select HNS that are likely to cause severe marine environmental effects as an essential step towards the establishment of a more effective preparedness and response to HNS incidents.

Abstract
UNLABELLED Several studies have demonstrated that obstructive sleep apnoea syndrome (OSAS) patients have a higher rate of road traffic accidents. Our study aimed to analyse any differences in OSAS patients between those who reported having had road traffic accidents and/or near misses and those who did not. METHODS We studied 163 patients with OSAS (apnoea- hypopnoea index (AHI)>10/h) diagnosed using nocturnal polysomnography (NPSG), all drivers, 18.4% of whom drove for a living. Patients were asked at their first clinical interview to self-report road traffic accidents and/or near misses over the past 3 years which had been caused by abnormal daytime drowsiness. This allowed patients to be divided into two groups, those who had had road traffic accidents and/or near misses and those who had not. Both were compared as to age, body mass index (BMI), Epworth Sleepiness Scale (ESS), daytime PaO2 and PaCO2, Functional Outcomes of Sleep Questionnaire (FOSQ) test and NPSG data. This latter was total sleep time (TTS), sleep efficiency, sleep stages, arousal index (ARI), AHI, minimal and average SaO2, % of time with SaO2 < 90% (T90), desaturation index (ODI), total duration of apnoea-hypopnoea (TDAH) (T test). RESULTS Group I (no road traffic accidents) No=89 patients; group II (road traffic accidents) No=74 patients. Age (years) was 57.6+/-11.8 vs. 54.7+/-10.9 (ns); male gender, 75% vs. 78.4%; ESS, 12.3+/-5.4 vs. 17.6+/-4.3 (p<0.001); BMI, (Kg/m2) 36.2+/-8.1 vs. 35.6+/-6.3 (ns); PaO2 (mmHg), 76.1+/-11.4 vs. 78.5+/-12.6 (ns); PaCO2 (mmHg), 42.6+/-5.1 vs. 42.2+/-4.7 (ns); FOSQ, 15.1+/-3.1 vs. 12.9+/-3.4 (p<0.001). NPSG data revealed differences only in AHI: 45.0+/-21.6 vs. 56.2+/-29.7 (p=0.01) and in TDAH (minutes), 98.5+/-63.7 vs. 133.3+/-83.2 (p=0,005). CONCLUSIONS In our experience patients who had road traffic accidents and/or near misses had a more severe OSAS, with higher AHI, excessive daytime sleepiness and lower quality of life.

Abstract
UNLABELLED Mycophenolate mofetil (MMF) and sirolimus (SRL) are effective immunosuppressive drugs with distinct safety profile. METHODS Kidney transplant recipients receiving tacrolimus (TAC)-based immunosuppressive regimen were randomized to receive fixed daily doses of MMF (2 g/d, n = 50) or SRL (one loading dose of 15 mg, 5 mg/d till day 7 and 2 mg/d thereafter, n = 50) without induction therapy. RESULTS No differences were observed in the incidence of the composite (biopsy-confirmed acute rejection, graft loss or death) end-point (18% vs. 16%, p = 1.000), biopsy confirmed acute rejection (12% vs. 14%, p = 1.000), one-yr patient (94% vs. 98%, p = 0.308), graft (92% vs. 98%, p = 0.168), and death-censored graft survival (98% vs. 100%, p = 0.317) comparing patients receiving MMF or SRL respectively. Patients receiving SRL showed worse safety outcomes, higher mean creatinine (1.6 +/- 0.5 mg/dL vs. 1.4 +/- 0.3 mg/dL, p = 0.007), higher proportion of patients with proteinuria (52.0% vs. 10.7%, p = 0.041), higher mean urinary protein concentrations (0.3 +/- 0.5 g/L vs. 0.1 +/- 0.2 g/L, p = 0.012), higher mean cholesterol concentration (217 mg/dL vs. 190 mg/dL, p = 0.030), and higher proportion of patients prematurely discontinued from randomized therapy (26% vs. 8%, p = 0.031). CONCLUSION In patients receiving TAC, MMF produced similar efficacy but superior safety profile compared with SRL.

Abstract
Visceral leishmaniasis (VL) caused by Leishmania chagasi is a growing public-health problem in many parts of the New World. Although several studies have focused on the consequences of environmental damage, human migration and land occupation on the incidence of VL, the effects on the disease of the substandard living conditions that often result from the process of urbanization have not been investigated in detail. The present study was based in the Brazilian city of Teresina, where, since 1980, there have been two large outbreaks of VL (one in 1981-1985 and the other in 1993-1996), each involving at least 1000 newly reported cases. The role of household structure and the provision of urban services in the city, as predictors of the occurrence of VL, was studied in a case-control investigation. After controlling for age, crowding, and the background incidence of VL in the area where the subjects lived, the risk of acquiring the disease was found to be significantly higher for those who lived in houses with an inadequate sewage system and those who had no regular rubbish collection. Improving household structure and providing basic urban services might be effective strategies for controlling the spread of VL in urban areas.

Abstract
The use of sirolimus (SRL) in combination with full doses of cyclosporin A (CsA) results in reduced one-year kidney allograft function, which is associated with shorter long-term allograft survival. We determined the effect of reduced CsA exposure on graft function in patients receiving SRL and prednisone. Ninety recipients of living kidney transplants receiving SRL (2 mg/day, po) were compared to 35 recipients receiving azathioprine (AZA, 2 mg kg-1 day-1, po). All patients also received CsA (8-10 mg kg-1 day-1, po) and prednisone (0.5 mg kg-1 day-1). Efficacy end-point was a composite of biopsy-confirmed acute rejection, graft loss, or death at one year. Graft function was measured by creatinine, creatinine clearance, and graft function deterioration between 3 and 12 months (delta1/Cr). CsA concentrations in patients receiving SRL were 26% lower. No differences in one-year composite efficacy end-point were observed comparing SRL and AZA groups (18 vs 20%) or in the incidence of biopsy-proven acute rejection (14.4 and 14.3%). There were no differences in mean +/- SD creatinine (1.65 +/- 0.46 vs 1.60 +/- 0.43 mg/dl, P = 0.48) or calculated creatinine clearances (61 +/- 15 vs 62 +/- 13 ml/min, P = 0.58) at one year. Mean +/- SD delta1/Cr (-11 +/- 17 vs -14 +/- 15%, P = 0.7) or the percentage of patients with >20% (26 vs 31%, P = 0.6) or >30% delta1/Cr (19 vs 17%, P = 1) did not differ between the two groups. The use of 2-mg fixed oral doses of SRL and reduced CsA exposure was effective in preventing acute rejection and preserving allograft function.

Abstract
BACKGROUND The worldwide fall in the rate of detection of new cases of leprosy has been partly attributed to the introduction of multidrug therapy and other improvements in control programs. However, the rate of detection of new cases has not decreased in Brazil. METHODS An analysis was made of the temporal distribution of 18,872 newly reported leprosy cases in Bahia, Brazil, from 1974 to 1997. Population denominators for the annual detection rate were obtained from population estimates based on the national census. Trends were presented by sex, date of birth, date of diagnosis, date of release, clinical form and by residence in areas which had notified cases in the 5 years prior to the rise in detection rate. RESULTS There was a marked increase in the new case detection rate (NCDR) in the State of Bahia, from 0.19 to 1.43 cases per 10,000 inhabitants during the study period, an increment of nearly 7% to 8% per year. This increase was also observed in people aged 14 years and younger. During this period tuberculoid and indeterminate forms have become predominant among women and younger people. The average age of male cases has shifted toward younger ages. CONCLUSIONS We interpret this pattern to mean that the increase in NCDR reflects a real increase in incidence of leprosy, whether or not accompanied by improved detection.

Abstract
OBJECTIVE To determine whether changes in the polymorphic trinucleotide (CAG) tract of the androgen receptor gene are associated with spermatogenic defects in patients with male infertility. DESIGN Case-control study of two ethnic groups. SETTING University referral centers for male infertility at Baylor College of Medicine, Houston, Texas, and National University Hospital, Singapore. PARTICIPANT(S) Two hundred and fifteen patients with male infertility and depressed spermatogenesis and 142 fertile controls. MAIN OUTCOME MEASURE(S) Size of androgen receptor CAG alleles according to fluorescent-labeled polymerase chain reaction and automated analysis using Genescan software (PE Biosystems Asia, Singapore), and statistical examination of its relation to clinical variables. RESULT(S) In U.S. patients, the mean androgen receptor CAG length was significantly longer in infertile patients than in fertile controls (21.95 +/- 0.31 vs. 20.72 +/- 0.52). Logistic regression showed that each unit increase in CAG length was associated with a 20% increase in the odds of being azoospermic. The odds ratio for azoospermia was sevenfold higher for patients with > or =26 CAG repeats than in those with <26 CAG repeats. Although mean CAG length in Singapore patients was longer than in the U.S. samples, long androgen receptor CAG alleles were significantly related to male infertility in both populations. CONCLUSION(S) Long (> or =26) androgen receptor CAG alleles, which are found in up to 25% of azoospermic men, are associated with male infertility and defective spermatogenesis. Conception in these men is possible with assisted reproductive technologies, as many have spermatozoa in their testes.

Abstract
Rabies virus glycoprotein (G) is a trimeric type I transmembrane glycoprotein that mediates both virus receptor recognition and low pH-induced membrane fusion. G can assume three different states: the 'native' state (N) detected at the virus surface, which is responsible for receptor binding, the activated hydrophobic state (A), which interacts with the target membrane as a first step in the fusion process, and the fusion-inactive conformation (I). These three states, which are structurally different, are in a pH-dependent equilibrium. This equilibrium is shifted toward the I state at low pH. This paper includes an investigation of the structure of the ectodomain of the PV strain of rabies virus when it is synthesized as a soluble form (G1-439) lacking the transmembrane and intracytoplasmic domains (residues 440-505). It is shown that, whatever the extracellular pH, G1-439 is secreted as a monomer that has the antigenic characteristics of the I state. This I-like state is not acquired in the acidic compartments of the Golgi but directly in the endoplasmic reticulum. Finally, membrane anchorage by the G transmembrane domain (G1-461) is sufficient for the G ectodomain to be folded into the native N form. These results emphasize the role of the G transmembrane domain in the correct folding of the ectodomain.

Abstract
The pharmacological profile of a novel specific platelet-activating factor (PAF) receptor antagonist-yangambin-isolated from the Brazilian plant Ocotea duckei Vattimo (Lauraceae), was investigated in the pentobarbitone-anaesthetized rabbit. The i.v. administration of PAF (0.03-3.0 microgram kg-1) induced marked but reversible hypotensive effects and mild reductions in the heart rate. Both effects are independent of the respiratory conditions imposed on the animals. Moreover, PAF (3.0 microgram kg-1, i.v.) induced a reversible decrease of the circulating levels of platelets and of polymorphonuclear leukocytes. Pretreatment with yangambin (10 and 20 mg kg-1, i.v.) dose-dependently attenuated PAF-induced cardiovascular changes and thrombocytopaenia. Nevertheless, the neutropenic leukopaenia elicited by PAF (3.0 microgram kg-1, i.v.) was not prevented by yangambin whereas the reference PAF antagonists WEB 2086 (2 mg kg-1, i.v.) and SR 27417 (1 mg kg-1, i.v.) significantly inhibited the phenomenon. The hypotensive effects of acetylcholine, histamine, and 5-hydroxytryptamine were not affected by prior administration of yangambin. It is concluded that yangambin is a selective antagonist of the cardiovascular effects of PAF which could be useful in pathological states characterized by abnormal PAF release, such as anaphylactic and septic shocks. Furthermore, yangambin might discriminate a PAF receptor subtype present in the cardiovascular system and platelets from the one existing in polymorphonuclear leukocytes in the rabbit.
