Abstract
PURPOSE/OBJECTIVE(S) The standard treatment for patients with advanced hepatocellular carcinoma (aHCC) is systemic therapy with or without stereotactic body radiation therapy (SBRT). We present our experience using SBRT as a definitive treatment for aHCC patients with poor access to systemic therapy. MATERIALS/METHODS We performed a retrospective review of patients treated with SBRT at the largest institution in Santiago, Chile between June 2016 and September 2022. All patients were deemed unsuitable for another locoregional treatment by the tumor board. We registered demographic, clinical and treatment characteristics. Additionally, treatment response rates using mRECIST criteria, overall survival (OS), local control (LC) and treatment toxicity were reported. We performed a multivariate analysis of variables using Cox proportion hazard ratio for OS and logistic regression for LC. RESULTS A total of 59 patients were included (41 males and 18 females; median age: 70 years [range: 38 - 85 years]), with a total of 63 treatment courses. Most common etiologies of chronic liver disease were nonalcoholic fatty liver disease (23%) and chronic alcohol consumption (20%). Most patients were classified as Child-Pugh Class A (80%). Barcelona Clinic Liver Cancer (BCLC) stage was 2%, 11%, 49% and 38% for stages 0, A, B and C, respectively, while macrovascular invasion was present in 10 (18%) of patients. Forty-six patients (73%) had been subjected to prior locoregional therapy and only 5 patients (8,5%) received systemic therapy after SBRT. Median tumor size was 7 cm. (range: 0.95 - 32 cm). Median radiation dose was 40 Gy (range: 26.5 - 50 Gy) in 5 fractions. Evaluation of radiological response was performed in 46 patients (79%), with complete response, partial response, stable disease and progressive disease in 41%, 43%, 7% and 9% of the cohort, respectively. With a median follow-up of 9 months (range: 0 - 58), 34 patients (58%) died with a median OS of 10.8 months (range: 0 - 28 months). At 12 months, OS was 65.2% (95% CI: 50.9 - 76.3) and at 24 months was 40.7% (95% CI: 26.2 - 54.6) In multivariate analysis tumor size (as a continuous variable) was the only significant variable for LC (OR 2.9 [CI 1.1 - 5.3; p 0.03]) and for OS (HR 3.4 [CI 1.3 - 6.7; p< 0.01]). Four patients developed grade 3 toxicity (3 thrombocytopenia and 1 duodenal ulcer) and only two treatments were suspended definitively. CONCLUSION Despite systemic therapy is the standard treatment for aHCC, a minor proportion of patients received the standard of care. SBRT is safe, feasible and a well-tolerated treatment option for aHCC with good clinical outcomes. To our knowledge, this is the first cohort reported of patients with aHCC treated with SBRT in Latin America.

Abstract
Introduction Clozapine, the first atypical antipsychotic, is a highly effective medication for patients with treatment-resistant schizophrenia. Robust evidence describes important risk for psychosis in immigrant population(2). Despite this, some studies suggest that immigrant patients are less treated and misdiagnosed due to cultural barriers(3,4). Clozapine and Electroconvulsive therapy tend to be less prescribed in immigrants(3). However, few studies assess differences in clozapine prescription between immigrants and non-immigrant psychotic inpatients. Objectives To describe and compare clozapine prescription between psychotic patients and non-psychotic patients in a sample of Acute and Chronic inpatients. Methods Patients who have presented, according to DSM-V criteria, one or more non-affective psychotic episodes, were recruited in Acute and Chronic inpatients units leading to a total sample of 198 patients. Immigrant condition was defined as “a person who comes to live permanently in a foreign country”. Demographic characteristics of patients, clinical data and main pharmacological treatment were recorded through a questionnaire. Comparative analysis was performed with IBM SPSS Statistics using Chi-Square Test and t-Student
test. Results From a total of 198patients clozapine was prescribed to 31(15,7%). From the total immigrant sample only 7,1% had prescribed clozapine compared to 24,2% from the locals(p<0.005). Significant differences in diagnosis associated to clozapine were found between both groups : Schizophrenia(57,1%immigrants, 57,1%locals), Schizoaffective disorder(14,3%immigrants, 41,7%locals) and Non specific psychosis (28,3%immigrants, 8,3%locals). Conclusions According to our results, immigrant psychotic inpatients receive less clozapine prescription compared to non-immigrant psychotic patients. There results should be considered to study barriers for clozapine prescription in this population and offer a treatment based in equality. Disclosure No significant relationships.

Abstract
Introduction
Major depressive disorder is a prevalent disease, in which one third of sufferers do not respond to antidepressants. Disturbance in the equilibrium of the gut microbiota has been involved in the pathophysiology of depression. Probiotics have the potential to be well-tolerated and cost-efficient treatment options. However, there is not enough evidence of the impact of probiotics in patients suffering MDD.
Objectives
The main aim of this revision is to assess those clinical trials that evaluate the effects of probiotic treatment in patients with MDD.
Methods
A research on the database PubMed has been done with the terms “probiotics” AND “MDD” and then a systematic review has been performed between those articles meeting the inclusion criteria.
Results
Most of the articles show an improvement of the depressive symptoms in outpatients with mild to moderate TDM after 8 week treatment with probiotics added to the treatment as usual. Those articles assessing inpatients with severe MDD after four weeks of treatment with probiotics added to their usual treatment didn’t find statistical differences between treatment with probiotics from placebo.
Conclusions
Probiotics may be useful in mild to moderate symptoms of MDD after 8 weeks treatment added to usual treatment. Nevertheless, further investigation in larger samples during more time. Moreover, a new awareness is raised about gut- brain axis pathophysiology, that would lead the path to new investigations about this relation so as the difference in depressed patients microbiome, tryptophan metabolism and the pro- inflammatory compounds that reach the blood-brain barrier because of the “leaky-gut”.

Abstract
1. Cobb and Ross broilers (200 of each sex and breed) were fed four phases of diets ad libitum formulated with balanced protein to match their amino acid requirements throughout growth. Ten birds per genotype were sampled and euthanised at two-weekly intervals from 14 to 112 d of age. All feathers were dry-plucked from each of the seven tracts (specific skin areas) and pulp (the centre of the feather filament) was removed from primary and secondary remiges.2. Daily losses of feathers were collected from an additional 20 individually-caged broilers of each breed. These feathers were separated into natal down, contour feathers, remiges and rectrices and then pooled by type, sex and genotype to quantify water and protein contents. Only those feathers collected from male Cobb 500 MX broilers were analysed for amino acid content.3. Amino acid contents of feathers from the seven tracts were measured only in Cobb males on days 1, 28 and 70; for pulp on days 28 and 70; and for the four types of moulted feathers.4. Protein content on a dry matter basis remained relatively constant over all ages and tracts during growth. Water content decreased with age in both sexes and genotype. Lysine and methionine content in feathers decreased with age while cystine, valine, leucine and serine increased. Lysine, methionine and histidine levels were higher in pulp than in mature feathers whereas cystine and valine were higher in mature feathers than in pulp.5. These results, together with information about moulting patterns in broilers, enabled the effects of age of the bird and of the type of feather, to be taken into account when determining the rate of deposition of amino acids in feathers.

Abstract
BACKGROUND To explore whether the combination of white matter hyperintensities (WMHs) and amyloid-beta (Aβ) deposition is associated with worse cognitive performance on cognitive composites (CCs) domain scores in individuals with subjective cognitive decline (SCD). METHODS Two hundred participants from the FACEHBI cohort underwent structural magnetic resonance imaging (MRI), 18F-florbetaben positron emission tomography (FBB-PET), and neuropsychological assessment. WMHs were addressed through the Fazekas scale, the Age-Related White Matter Changes (ARWMC) scale, and the FreeSurfer pipeline. Eight CCs domain scores were created using the principal component analysis (PCA). Age, sex, education, and apolipoprotein E (APOE) were used as adjusting variables. RESULTS Adjusted multiple linear regression models showed that FreeSurfer (B - .245; 95% CI - .1.676, - .393, p = .016) and β burden (SUVR) (B - .180; 95% CI - 2.140, - .292; p = .070) were associated with face-name associative memory CCs domain score, although the latest one was not statistically significant after correction for multiple testing (p = .070). There was non-significant interaction of these two factors on this same CCs domain score (p = .54). However, its cumulative effects on face-name associative performance indicated that those individuals with either higher WMH load or higher Aβ burden showed the worst performance on the face-name associative memory CCs domain score. CONCLUSIONS Our results suggest that increased WMH load and increased Aβ are independently associated with poorer episodic memory performance in SCD individuals, indicating a cumulative effect of the combination of these two pathological conditions in promoting lower cognitive performance, an aspect that could help in terms of treatment and prevention.

Abstract
IntroductionMeta-analytic evidence suggests that migrants have higher risk for psychotic disorders. Likewise, growing evidence relate developmental trauma (emotional, sexual, physical abuse and neglect in childhood or adolescence) as a causal factor for psychotic symptoms. However, few studies examine developmental trauma in migrant populations.ObjectivesThe aim of this study is to describe and compare developmental trauma exposure prevalence between immigrant and non-immigrant psychotic patients in Barcelona.MethodsPatients who have presented, according DSM-V criteria, one or more non-affective psychotic episodes, were recruited in Acute and Chronic inpatients units at Hospital del Mar (Barcelona), leading to a total sample of 77 patients. Demographic characteristics of patients, clinical data and main pharmacological treatment were recorded through a questionnaire. Developmental trauma exposure was assessed by Childhood Trauma Questionnaire (CTQ). Comparative analysis was performed with IBM SPSS using Chi-Square Test and t-Student test.ResultsFrom a total of 77 patients, 43 were immigrants and 34 were non-immigrants. Exposure to traumatic events showed significant differences between immigrants and non-immigrant in Child emotional abuse (64,4% immigrants, 35,3% non-immigrant), Child physical abuse (51,2% immigrants, 14,7% non-immigrant), Child Sexual Abuse (41,9% immigrants, 11,8% non-immigrant) and physical neglect (62,8% immigrants, 26,5% non-immigrant). Emotional neglect exposure was no significant between both groups. Total mean CTQ score was 37,53 in immigrants group and 52,60 in non-immigrant group.ConclusionsAccording to our results, there are important and significant differences in developmental trauma exposure between immigrant and non-immigrant psychotic patients. These results should be considered by clinicians in order to design assessment program for this population.DisclosureNo significant relationships.

Abstract
Introduction Migration is a highly defining life event which can lead to mental distress. It constitutes an overall risk factor for psychiatric disorders. However, psychotherapeutic treatment in immigrant patients is considered to be more complex, and the outcome appears to be less favorable than in patients without a migration background. Objectives The aim of this study is to compare psychotherapy assessment between immigrant and non-immigrant psychotic patients in Barcelona. Methods Patients who have presented, according DSM-V criteria, one or more non-affective psychotic episodes, were recruited in Acute and Chronic inpatients units at Hospital del Mar (Barcelona), leading to a total sample of 77 patients. Demographic characteristics of patients, clinical data and main pharmacological treatment were recorded through a questionnaire. Database information was completed with electronic medical records. Comparative analysis was performed with IBM SPSS using Chi-Square and t-Student test Results
From a total of 77 patients, 43 were immigrants and 34 were non-immigrants. From the total immigrants only 30,2% received psychotherapy compared to 79,4% from the non-immigrants. The most prevalent therapy received in both groups was cognitive behavioural therapy. From the immigrants group only 2,3% received psychoeducation compared to 11,8% from the non-immigrant group. Conclusions According to our results, there are important and significant differences in psychotherapy assessment in migrant psychotic patients. In order to improve the mental health treatment of immigrant patients, the reasons for this poor outcome need to be investigated. These results should be considered by clinicians in order to design assessment program for this population. Disclosure No significant relationships.

Abstract
1. Changes in feather length and weight and daily losses of down, contour feathers, remiges and retrices were studied in two commercial broiler strains to determine feather growth and moult in broilers up to 112 d of age. 2. Ten pens of 20 chicks for each sex x strain were fed adequate amounts of dietary protein in a four-phase feeding programme. Ten birds were sampled per genotype at 14, 28, 42, 56, 70, 84, 98 and 112 d. Feather loss was determined for individual birds caged within a nylon net. 3. All feathers were dry-plucked from each of seven tracts, with representative feathers from the capital-cervical, dorsopelvic and interscapular, pectoral and femoral tracts being randomly selected. Three rectrices of the dorsocaudal tract and three primaries and secondaries of the humeral-alar tract of the right wing were evaluated. 4. The length of the selected feathers was measured, and the feathers from each tract and from the whole bird were weighed. 5. A wide range of rates of maturing (0.0250-0.0907/d) and mature weights (9.62-52.9 g) were evident between sampled tracts. 6. Feather weight failed to predict some moults which were detected by the measurement of feather losses. From the weight data, moulting was evident only in the humeral-alar and dorsocaudal tracts, whereas, when daily losses were measured, contour feathers accounted for over 0.7 proportion of feather losses. Logistic equations adequately described the cumulative losses of down, contour feathers and remiges. 7. Feather loss needs to be considered when feather growth is determined from feather weight at different ages. 8. The rate of maturing (B) of feathers was numerically higher in Ross males and females than in the Cobb strain. In females, B was higher than in males (0.0483 vs. 0335/d) but the mature weight was lower (162 vs. 230 g).

Abstract
1. The potential growth of feathers and feather-free body and their chemical components was measured in two commercial broiler strains. 2. A total of 200 chicks of each sex x strain were fed adequate amounts of dietary protein using a four-phase feeding programme. Ten birds per genotype were sampled at 14, 28, 42, 56, 70, 84, 98 and 112 d of age. They were weighed before and after being dry-plucked to determine the weight of feathers, and the feather-free body was then minced and analysed for water, protein and lipid. 3. Body weights and chemical composition of males of the two strains were similar throughout the trial. Females of the two strains differed only in their body lipid contents, with mature Cobb females being higher than Ross (1371 vs. 1210 g). 4. Mature body weights of males and females from both strains averaged 8420 g and 6650 g; mature body protein weights averaged 1555 g and 1030 g; and mature body lipid contents averaged 908 and 1290 g, respectively. 5. Rates of maturing per day of body weights of males and females of both strains averaged 0.0385 and 0.0368; feather-free body protein was 0.0316 and 0.0348 and body lipid was 0.0503 and 0.0375, respectively. The rates for body lipid differed between Cobb and Ross females (0.0352 vs. 0.0397/d). Separate equations were required for males and females to describe the allometric relationship between lipid and protein in the feather-free body. 6. The rate of maturing of feathers in females was higher than in males (0.0526 vs. 0398/d) and the mature weight was lower (205 vs. 266 g), respectively. Mature body weights of broilers in this trial were considerably higher than those measured using the same protocol 24 years ago, whereas rates of maturing remained the same.

Abstract
BACKGROUND Peripheral biomarkers that identify individuals at risk of developing Alzheimer's disease (AD) or predicting high amyloid beta (Aβ) brain burden would be highly valuable. To facilitate clinical trials of disease-modifying therapies, plasma concentrations of Aβ species are good candidates for peripheral AD biomarkers, but studies to date have generated conflicting results. METHODS The Fundació ACE Healthy Brain Initiative (FACEHBI) study uses a convenience sample of 200 individuals diagnosed with subjective cognitive decline (SCD) at the Fundació ACE (Barcelona, Spain) who underwent amyloid florbetaben(18F) (FBB) positron emission tomography (PET) brain imaging. Baseline plasma samples from FACEHBI subjects (aged 65.9 ± 7.2 years) were analyzed using the ABtest (Araclon Biotech). This test directly determines the free plasma (FP) and total plasma (TP) levels of Aβ40 and Aβ42 peptides. The association between Aβ40 and Aβ42 plasma levels and FBB-PET global standardized uptake value ratio (SUVR) was determined using correlations and linear regression-based methods. The effect of the APOE genotype on plasma Aβ levels and FBB-PET was also assessed. Finally, various models including different combinations of demographics, genetics, and Aβ plasma levels were constructed using logistic regression and area under the receiver operating characteristic curve (AUROC) analyses to evaluate their ability for discriminating which subjects presented brain amyloidosis. RESULTS FBB-PET global SUVR correlated weakly but significantly with Aβ42/40 plasma ratios. For TP42/40, this observation persisted after controlling for age and APOE ε4 allele carrier status (R2 = 0.193, p = 1.01E-09). The ROC curve demonstrated that plasma Aβ measurements are not superior to APOE and age in combination in predicting brain amyloidosis. It is noteworthy that using a simple preselection tool (the TP42/40 ratio with an empirical cut-off value of 0.08) optimizes the sensitivity and reduces the number of individuals subjected to Aβ FBB-PET scanners to 52.8%. No significant dependency was observed between APOE genotype and plasma Aβ measurements (p value for interaction = 0.105). CONCLUSION Brain and plasma Aβ levels are partially correlated in individuals diagnosed with SCD. Aβ plasma measurements, particularly the TP42/40 ratio, could generate a new recruitment strategy independent of the APOE genotype that would improve identification of SCD subjects with brain amyloidosis and reduce the rate of screening failures in preclinical AD studies. Independent replication of these findings is warranted.

Abstract
BACKGROUND Long-term longitudinal studies with multimodal biomarkers are needed to delve into the knowledge of preclinical AD. Subjective cognitive decline has been proposed as a risk factor for the development of cognitive impairment. Thus, including individuals with SCD in observational studies may be a cost-effective strategy to increase the prevalence of preclinical AD in the sample. OBJECTIVES To describe the rationale, research protocols and baseline characteristics of participants in the Fundació ACE Healthy Brain Initiative (FACEHBI). DESIGN FACEHBI is a clinical trial (EudraCT: 2014-000798-38) embedded within a long-term observational study of individuals with SCD. SETTING Participants have been recruited at the memory clinic of Fundació ACE (Barcelona) from two different sources: patients referred by a general practitioner and individuals from an Open House Initiative. PARTICIPANTS 200 individuals diagnosed with SCD with a strictly normal performance in a comprehensive neuropsychological battery. MEASUREMENTS Individuals will undergo an extensive neuropsychological protocol, risk factor assessment and a set of multimodal biomarkers including florbetaben PET, structural and functional MRI, diffusion tensor imaging, determination of amyloid species in plasma and neurophthalmologic assessment with optical coherence tomography. RESULTS Two hundred individuals have been recruited in 15 months. Mean age was 65.9 years; mean MMSE was 29.2 with a mean of 14.8 years of education. CONCLUSIONS FACEHBI is a long-term study of cognition, biomarkers and lifestyle that has been designed upon an innovative symptom-based approach using SCD as target population. It will shed light on the pathophysiology of preclinical AD and the role of SCD as a risk marker for the development of cognitive impairment.

Abstract
To follow-up loci discovered by the International Genomics of Alzheimer's Disease Project, we attempted independent replication of 19 single nucleotide polymorphisms (SNPs) in a large Spanish sample (Fundació ACE data set; 1808 patients and 2564 controls). Our results corroborate association with four SNPs located in the genes INPP5D, MEF2C, ZCWPW1 and FERMT2, respectively. Of these, ZCWPW1 was the only SNP to withstand correction for multiple testing (P=0.000655). Furthermore, we identify TRIP4 (rs74615166) as a novel genome-wide significant locus for Alzheimer's disease risk (odds ratio=1.31; confidence interval 95% (1.19-1.44); P=9.74 × 10(-)(9)).

Abstract
The antiplasmodial activity of phospholipases A(2) (PLA(2)) isolated from different animals has been studied. We explored the in vitro anti Plasmodium falciparum effect of a fraction containing crotoxin, Crotoxin B and whole venom of the rattlesnake Crotalus durissus cumanensis. Fraction II (crotoxin complex) was obtained by size exclusion chromatography, whereas Crotoxin B was purified by RP-HPLC. The whole venom is active against the parasite at concentrations of 0.17±0.03 μg/ml, fraction II at 0.76±0.17 μg/ml and Crotoxin B at 0.6±0.04 μg/ml. Differences were observed in the cytotoxic activity against peripheral mononuclear cells, with Crotoxin B exhibiting the highest cytotoxicity. The concentration of Crotoxin B required to exert cytotoxic activity was higher than that required to exert antiplasmodial activity. Lethality in mice confirmed the higher toxicity and neurotoxicity of whole venom and fraction II, whereas Crotoxin B was not lethal at the doses tested. These results suggest the potential of Crotoxin B as a lead compound for antimalarial activity.

Abstract
Cryopreservation of fish gametes has been studied extensively in the last few decades, but the successful cryopreservation of fish embryos remains elusive. However, recent studies using short-term chilling techniques have shown that it is possible to store embryos at low temperatures with no significant loss in viability. Information on cryopreservation of Neotropical freshwater fish embryos has so far been very limited in the literature. In the present study, chilling protocols for storage of pacu embryos at -8°C for up to 24 h were studied using different concentrations of sucrose in methanol. Embryos tolerated the subzero temperature for up to 6 h with no adverse effects (P > 0.05). After 12 h chilling, hatching rate of 64.0 +/- 3.5 percent was recorded. Low temperature storage of pacu embryos by chilling is detailed here for the first time. Further studies are needed to extend the storage time and to improve the hatching rate.

Abstract
Actualmente se ha verificado la disminución y desaparición de muchas especies de peces en varios ambientes acuáticos en el Brasil. Como forma de minimizar ese impacto, programas de repoblación vienen siendo utilizados con más intensidad, entretanto, se le ha dado poca importancia a la variabilidad genética, parámetro fundamental para cualquier práctica de conservación. El objetivo de este estudio fue analizar la diversidad genética de lotes de Piaractus mesopotamicus usados en programas de repoblación, mediante el marcador molecular RAPD. Se analizaron 60 reproductores de dos estaciones de piscicultura ubicadas en las ciudades de Sapopema (S) y Cambará (C) en el Estado del Paraná (Brasil) y 30 larvas de la progenie del lote de Sapopema (PS).

Abstract
Avaliou-se o efeito do sistema seminatural na diversidade genética de um estoque de Brycon orbignyanus, utilizado em programas de repovoamento, com o marcador molecular RAPD. Vinte e quatro reprodutores, 12 machos e 12 fêmeas e 95 larvas da progênie foram analisados. Os nove primers utilizados produziram 90 fragmentos, dos quais 94,4% foram polimórficos. Houve diferença significativa na frequência de 20 dos 90 fragmentos entre os reprodutores e sua progênie sem a presença de fragmentos exclusivos. O índice de diversidade genética de Shannon, a porcentagem de fragmentos polimórficos e a diversidade genética de Nei foram mais altos nos indivíduos da progênie. A similaridade genética foi maior nos indivíduos do estoque de reprodutores. A análise de variância molecular mostrou que a maior parte da variação está dentro de cada grupo (89,1%) e não entre os grupos (10,9%). A identidade e a distância genética entre os estoques foram de 0,944 e 0,057, respectivamente. Assim, a utilização do sistema seminatural evitou a mortalidade de reprodutores B. orbignyanus e conservou a variabilidade genética da progênie.

Abstract
This study was carried out to morphologically characterize and classify the stages of gonad development in different Nile tilapia strains (Oreochromis niloticus). Eighty-four and ninety-two ovaries from Bouaké and Chitralada strains, respectively, were evaluated at different ovarian developmental phases: initial (104 days of culture), intermediate (152 days of culture), and the final (279 days of culture). The ovaries were microscopically evaluated and submitted to histological processing and hematoxylin-eosin staining to determine their characteristics and be classified. No morphological differences in ovaries between strains were observed during the initial phase (stage A - immature). During the intermediate growing phase, higher gonad development was observed for Chitralada strain (stage B - maturation) in comparison with Bouaké strain (stage A - immature). During the final growing phase, no differences between strains were observed for morphological characteristics (stage C - mature). Despite the similarities in reproductive behavior of the Bouaké and Chitralada females at the end of the final growing phase (gain weight phase), differences for macroscopic and microscopic aspects and oocytes during the initial and intermediate growing phases of the strains were observed.

Abstract
Avaliou-se a variabilidade genética dos estoques de reprodutores e dos peixes jovens de Piaractus mesopotamicus de três pisciculturas do estado do Paraná, utilizadas no programa de aumento de estoque de peixes no rio Paranapanema. Foi utilizado o marcador RAPD para avaliar as amostras do estoque de reprodutores e dos peixes jovens das pisciculturas de Palotina, Cambará e Andirá. A porcentagem de fragmentos polimórficos e o índice de diversidade genética de Shannon dos estoques de reprodutores variaram de 75,0% a 71,4% e de 0,434 a 0,376, respectivamente. Os peixes jovens das pisciculturas apresentaram valores mais elevados para ambos os parâmetros, com exceção da piscicultura de Palotina, na qual o índice de diversidade genética de Shannon foi semelhante. Os estoques de reprodutores apresentaram alta variabilidade genética, e esta foi mantida nos peixes jovens.

Analisou-se a diversidade genética de estoques de reprodutores de Tambaqui (Colossoma macropomum), mediante o uso de marcador RAPD, utilizando-se 10 primers para analisar 30 amostras do estoques de reprodutores das pisciculturas de Boa Esperança e Vale Verde, localizadas no Estado de Rondônia. A porcentagem de fragmentos polimórficos e o índice de diversidade genética de Shannon foram altos nos dois estoques de reprodutores. O estoque de reprodutores de Boa Esperança apresentou um fragmento exclusivo. A diferenciação genética foi baixa e o número de migrantes por geração foi alto entre os estoques de reprodutores. O dendrograma não separou os indivíduos dos estoques de reprodutores em grupos distintos. Há alta variabilidade genética nos estoques de reprodutores, um pouco inferior no estoque de Vale Verde, e há grande proximidade genética entre os indivíduos dos estoques de reprodutores.

Abstract
BACKGROUND Endoscopic ligation is the treatment of choice for bleeding esophageal varices. The usefulness of additional sclerotherapy is not clear. AIM To assess the effectiveness of ligation followed by sclerotherapy in the treatment of variceal bleeding. PATIENTS AND METHODS Forty eight patients with variceal bleeding admitted for emergency treatment and 73 patients admitted for elective treatment were studied. Varices were ligated until a significant reduction in size was achieved. Eradication was completed with the injection of 1% polidocanol. RESULTS In 34 of 48 patients admitted for emergency treatment, the site of variceal rupture was identified. In all these subjects, and in 13 of 14 patients in whom the rupture site was not identified, hemorrhage was stopped with the procedure. Varices were eradicated in 108 of the 121 patients. Hemorrhage recidivated in 12.5% of patients admitted for emergency treatment, in a period of 14 months of follow up and in 9.6% of those admitted for elective treatment, in a period of 16 months follow up. Mortality was 14, 18 and 57% among patients classified as Child Pugh A, B or C, respectively. CONCLUSIONS Endoscopic ligation is effective in the treatment of variceal bleeding. Adding sclerotherapy, variceal eradication is achieved in a high percentage of patients. Survival depends on hepatic function.

Abstract
The exact mechanisms by which growth hormone (GH) damages the kidney inducing diabetic nephropathy has not yet been elucidated. Recently, it has been shown that transferrin has the same diabetogenic effects of GH, being its mediator. Transferrin was studied using immunohistochemistry and immunoelectron microscopy in cases of early diabetic nephropathy, and in controls. Transferrin was only found in diabetic cases in podocytes and Bowman's capsule cells, but also in the tubular cells of both diabetic and non-diabetic controls. Immuno-electron microscopy for the presence of transferrin showed positive signals in the cytoplasm of diabetic podocytes, but not in pedicels. This selective deposition was associated with signs of organelle and cytoskeleton damage. On the basis of previous evidence and present glomerular findings, these results suggest an indirect diabetogenic effect on the kidney by GH mediated through transferrin.

Abstract
Bruton's tyrosine kinase (Btk), a nonreceptor cytoplasmic tyrosine kinase belonging to the Tec family of kinases, has been shown to be critical for B cell proliferation, differentiation, and signaling. Loss-of-function mutations in the Btk gene lead to X-linked agammaglobulinemia (XLA), a primary immunodeficiency in humans, and the less severe condition xid in mice. Although Btk is mainly localized in the cytoplasm under steady state conditions, it translocates to the plasma membrane upon growth factor stimulation and cross-linking of the B cell receptor. Nevertheless, in ectopically as well as endogenously Btk-expressing cells, it can also translocate to the nucleus. Deletion of the pleckstrin homology (PH) domain (DeltaPH1) leads, however, to an even redistribution of Btk within the nucleus and cytoplasm in the majority of transfected cells. In contrast, an SH3-deleted (DeltaSH3) mutant of Btk has been found to be predominantly nuclear. We also demonstrate that the nuclear accumulation of DeltaPH1 is dependent on Src expression. This nucleocytoplasmic shuttling is sensitive to the exportin 1/CRM1-inactivating drug, leptomycin B, indicating that Btk utilizes functional nuclear export signals. In addition, while the DeltaPH1 mutant of Btk was found to be active and tyrosine-phosphorylated in vivo, DeltaSH3 displayed decreased autokinase activity and was not phosphorylated. Our findings indicate that the nucleocytoplasmic shuttling of Btk has implications regarding potential targets inside the nucleus, which may be critical in gene regulation during B cell development and differentiation.

Abstract
Forty-six different species collected in the Mosetene ethnia, dwelling in the Andean Piedmont of Bolivia, were screened for antimalarial properties. Thirty-three extracts were screened for antimalarial activity in vitro on Plasmodium falciparum chloroquine resistant strain (Indo), and forty-seven extracts were evaluated in vivo on the rodent malaria P. vinckei petteri 279BY. Only two plants are specifically used in combination by the Mosetene against malaria attack (Hymenachne donacifolia and Tesseria integrifolia), but they did not display any activity in vivo at 1000 mg/kg. The in vivo most active extracts were Swietenia macrophylla bark, Trema micrantha bark and Triplaris americana bark, not all of them were used for antimalarial purposes by the Mosetene. The following extracts were moderately active: Jacaratia digitata inner bark and Momordica charantia aerial part (both traditionally used as febrifuge), Kalanchoe pinnate aerial part (used in inflammatory processes), Lunania parviflora twigs and leaves, Phyllanthus acuminatus (used as piscicide), Tynanthus schumannianus fruit (used against diarrhoea), Triumfetta semitrilobata (used as febrifuge, to alleviate kidney and gynecological pain) and finally Solanum mammosum fruit (used against scabies). We present here the results of this screening, emphazing on the in vivo antimalarial activity of the selected plants. The antimalarial in vivo activity of the selected species, in relation with their traditional Mosetene use is then discussed.

Abstract
Bruton's tyrosine kinase (Btk) is a member of the Tec family of protein tyrosine kinases (PTK) characterized by an N-terminal pleckstrin homology domain (PH) thought to directly interact with phosphoinositides. We report here that wild-type (wt) and also a gain-of-function mutant of Btk are redistributed following a wide range of receptor-mediated stimuli through phosphatidylinositol 3-kinase (PI 3-K) activation. Employing chimeric Btk with green fluorescent protein in transient transfections resulted in Btk translocation to the cytoplasmic membrane of live cells through various forms of upstream PI 3-K activation. The redistribution was blocked by pharmacological and biological inhibitors of PI 3-K. A gain-of-function mutant of Btk was found to be a potent inducer of lamellipodia and/or membrane ruffle formation. In the presence of constitutively active forms of Rac1 and Cdc42, Btk is co-localized with actin in these regions. Formation of the membrane structures was blocked by the dominant negative form of N17-Rac1. Therefore, Btk forms a link between a vast number of cell surface receptors activating PI 3-K and certain members of the Rho-family of small GTPases. In the chicken B cell line, DT40, cells lacking Btk differed from wt cells in the actin pattern and showed decreased capacity to form aggregates, further suggesting that cytoskeletal regulation mediated by Btk may be of physiological relevance.
