Abstract: The struggles?for land possession and deforestation were some results of the recent occupation process in the Amazon. Family farming was the target of land policies in the region, with recurring failures. Issues related to land governance and pro-poor policies have returned to the discussions, especially by the food production. This study aims to evaluate the relationship between the educational level, land access and sustainable land use among farmers in Acre State, Brazil, in the periods 1996/1997 and 2006/2007. Based on a sample, the methodology worked with variables related to the educational level, the access and the use of land, economic results and solid garbage. The results show that the higher educational level is directly related to the land access security and inversely proportional to sustainability in the land use type. Furthermore, production difficulties are leading to greater market dependence and, consequently, to increased generation of solid garbage, whose disposal may be better directed by improving the farmers’ education.

ISRN Urology , 2014, DOI: 10.1155/2014/659383
Abstract: Single-incision slings were introduced in the surgical treatment of female stress urinary incontinence (SUI) to lessen the morbidity associated with traditional midurethral slings. However, long-term reports on patient satisfaction are still scarce. This study describes the outcome of women treated with Mini-Arc at a mean follow-up of 45 months. In a previous report on 105 women with 15-month mean follow-up, 84 (80%) were found cured and 12 (11%) improved. Now, with a mean follow-up of 45 months, cured/improved patients were reassessed by telephone and completed Patient Global Impression of Improvement (PGI-I), Patient Global Impression of Severity (PGI-S), rated their improvement in a 0–100 scale, and answered if they would recommend the procedure. At 45-month follow-up, 73 women cured/improved were available for evaluation. Over 80% of the cured patients rated the improvement of SUI by the PGI-I as “very much better” or “much better,” reported their urinary tract condition to be “normal” on PGI-S, and described their improvement >70%. Ninety percent would recommend this procedure to a friend. The improved-patient population is very small . This study shows that the majority of patients cured/improved after Mini-Arc placement maintain a high degree of satisfaction at a long-term evaluation. 1. Introduction According to the European Association of Urology Guidelines on Urinary Incontinence, concerning the treatment of female stress urinary incontinence (SUI), the retropubic insertion of a midurethral synthetic sling (MUS) gives equivalent patient-reported cure of SUI at 12 months, when compared to colposuspension [1]. These guidelines also report that midurethral synthetic sling inserted by either the transobturator (TO) or retropubic (RP) route gives equivalent patient-reported outcome at 12 months [1]. With an obvious trending towards less and less invasive surgical options, single-incision vaginal slings (SIS) have emerged. They require very limited intracorporeal dissection, proposing to further increase safety of suburethral slings, without jeopardizing the success rates reported by conventional RP and TO access [2]. These SIS outcomes are comparable with conventional MUS at short-term follow-up [3–5]. Although sparse, two-year follow-up studies are available and seem to maintain steady success rates over this time [6, 7]. Longer follow-up time reports are needed, to ensure that, in the long run, these SIS offer constant success rates. The objective of this study is to describe the outcome of women treated with Mini-Arc at a mean follow-up of 45

Abstract: This is an extension of a 6 month study in which 21 frail elderly patients with refractory urinary retention and unfit for surgery were submitted to intraprostatic injection of BoNT/A-200U, by ultrasound guided transrectal approach. In spite of frail conditions, eleven patients could be followed during 18 months. Prostate volume, total serum PSA, maximal flow rate (Qmax), residual volume (PVR) and IPSS-QoL scores were determined at 1, 3, 6, 12 and 18 months post-treatment.Mean prostate volume at baseline, 82 ± 16 ml progressively decreased from month one coming to 49 ± 9,5 ml (p = 0,003) at month six. From this moment on, prostate volume slowly recovered, becoming identical to baseline at 18 months (73 ± 16 ml, p = 0.03). Albeit non significant, serum PSA showed a 25% decrease from baseline to month 6. The 11 patients resumed spontaneous voiding at month one. Mean Qmax was 11,3 ± 1,7 ml/sec and remained unchanged during the follow-up period. PVR ranged from 55 ± 17 to 82 ± 20 ml and IPSS score from10 to 12 points.Intraprostatic BoNT/A injection is safe and can reduce prostate volume for a period of 18 months. During this time a marked symptomatic improvement can be maintained.Botulinum Toxin type A (BoNT/A), the strongest biological neurotoxin known to man, recently has been investigated as a treatment for multiple disorders, including lower urinary tract dysfunction [1].BoNT/A investigation for the treatment of benign prostatic enlargement (BPE) due to benign prostatic hyperplasia (BPH) started in 2003 [2] after the experimental demonstration that intraprostatic injection of the neurotoxin induced prostatic atrophy in the Rat [3]. In an exploratory study, which involved injection of 200 U of BoNT/A (Botox) in moderate to large prostate glands, a rapid prostate volume decrease was induced and still present at 12 months [2]. Following this study, other groups reported similar findings when injecting prostate glands of 50 ml or larger [4-7]. BoNT/A injection in smalle

Abstract: Fifty gilts were used, with initial weight of 15.11 + 1.34 kg, distributed in a random block experimental design, with five treatments (digestible lysine levels), five replicates and two animals per stall, which were considered one experimental unit. The criteria for the formation of the blocks were the animal initial weight. Treatments consisted in a basal diet with 19.41% of CP e 3,221 kcal of ME/kg, supplemented with L-lysine HCl, resulting on diets with 0.88, 0.98, 1.08, 1.18 and 1.28% of digestible lysine. Diets were supplemented with increasing levels of industrial aminoacids, resulting on diets with constant ratio of essential aminoacids and lysine, based on true digestible. There was no effect of levels of digestible lysine on daily feed intake and daily weight gain. A quadratic effect (P < 0.06) was observed on feed conversion that improved until an estimated level of 1.08% of digestible lysine, which corresponded to a digestible lysine intake of 11.60 g/day. The level of 1,08% of digestible lysine, which corresponded to a digestible lysine intake of 11.60 g/day, provided the best performance results for gilts and a high genetic potential for lean deposition from 15 to 30kg. Foram utilizadas 50 fêmeas suínas, com peso inicial de 15,11 + 1,34 kg, distribuídas em delineamento experimental de blocos ao acaso, com cinco tratamentos (níveis de lisina digestível), cinco repeti es e dois animais por baia, o que constituiu a unidade experimental. Como critério para forma o dos blocos, foi utilizado o peso dos animais. Os tratamentos corresponderam a uma ra o basal com 19,41% de PB e 3.221 kcal de EM/kg, suplementada com L-lisina HCl, resultando em ra es com 0,88, 0,98, 1,08, 1,18 e 1,28% de lisina digestível. As ra es foram suplementadas com níveis crescentes de aminoácidos industriais, resultando em ra es com rela es constantes entre os aminoácidos essenciais e a lisina, com base na digestibilidade verdadeira. N o foi observado efeito dos níveis de lisina digestível sobre o consumo de ra o e ganho de peso diário. Observou-se efeito quadrático (P<0,06) dos tratamentos sobre a convers o alimentar, que melhorou até o nível estimado de 1,08% de lisina digestível, correspondendo a um consumo de lisina digestível de 11,60 g/dia. O nível de 1,08% de lisina digestível, correspondente a um consumo de 11,60 g/dia de lisina digestível, proporcionou os melhores resultados de desempenho para fêmeas suínas de alto potencial genético, para deposi o de carne magra na carca a dos 15 aos 30 kg.

Abstract: an experiment was conduced with the objective of evaluating the effects of diet formulation methods and supplementation of ractopamine (rac) on the performance and carcass characteristics of finishing barrows. sixty commercial hybrid swines were used, distributed in a randomized experimental block design, in a 2 x 3 factorial arrangment, with two levels of rac and three methods of diet formulation. supplementation with rac improved the final weight, daily weight gain (dwg) and feed conversion (fc) of the finishing barrows. addition of rac improved also the carcass characteristics by reducing the backfat thickness in point p1 and increase daily lean meat deposition rate. diets formulated based in the concept of ideal protein or by the increase of soybean meal provided better results on fc, but did not influence significantly daily feed intake, dwg and carcass characteristics. finishing barrows supplemented with rac during 21 or 28 days showed better performance and carcass quality. diets formulated to attend the levels of digestible lysine by the inclusion of l-lysine hcl with the adjustment of other amino acids for ideal protein relation (ideal protein) or by the greater inclusion of soybean meal (increase of cp) provided better results of feed conversion in finishing borrows supplemented with rac during 28 days.

Abstract: an experiment was carried out with the objective of evaluating the effect of different lysine levels in diets supplemented or not with ractopamine (rac) on the performance and carcass characteristics of finishing barrows. forty commercial hybrid swines were distributed to a randomized experimental block design, in a 2 x 2 factorial arrangement, with two digestible lysine levels (0.67 and 0.87%), with adjustment for the others amino acids to achieve an ideal protein relationship, and two levels of rac (0 and 5.0 ppm) in a period of 28 days. supplementation with rac resulted in a higher daily weight gain and of daily lean meat deposition rate, and better feed conversion. the lysine levels did not affect the performance of the animals, however there was a reduction of backfat thickness on p1 and p2 points and increased the daily lean meat deposition rate on the carcass of swine fed with diets containing 0.87% of digestible lysine when in vivo evaluated. in conclusion, performance and carcass characteristics of swine fed with diets supplemented with rac in the finishing phase improved; however the effect of rac on the loin depth was higher for the higher level of 0.87% of digestible lysine.

Abstract: Fifty barrows with high genetic potential for lean gain in the carcass and initial body weight of 29.9 1.57 kg were used to evaluate the effect of feeding different lysine levels on performance and carcass protein deposition rate. A randomized block experimental design, with five treatments, five replicates and two animals per replicate was used. Treatments corresponded to five digestible lysine levels (0.70, 0.80, 0.90, 1.00, and 1.10%) with variable proportions of corn and soybean meal. Animals were kept in the experiment until they reached the final body weight of 60.5 1.74 kg. Linear (P<0.01) increasing effect was observed for the daily weight gain (DWG), but the linear response plateau model was that better fitted to the DWG data, that stabilized in a plateau starting from the level of 1.02% of digestible lysine. Significant linear effects were observed for the feed conversion, daily lysine intake and daily protein deposition by increasing dietary lysine levels but no diet effect was found for the daily feed intake. Digestible lysine level of 1.02%, corresponding to a digestible lysine intake of 19.50g/day, provides the best results of performance and protein deposition in barrows with high genetic potential for lean meat deposition in the carcass in the phase from 30 to 60 kg. Foram utilizados 50 suínos machos castrados de alto potencial genético para deposi o de carne magra na carca a e peso inicial de 29,9 1,57 kg, para avaliar diferentes níveis de lisina sobre o desempenho e as características de carca a. Foi usado delineamento de blocos ao acaso, com cinco tratamentos, cinco repeti es e dois animais por repeti o. Os tratamentos consistiram de cinco níveis de lisina digestível (0,70; 0,80; 0,90; 1,00 e 1,10%), obtidos variando-se a propor o de milho e farelo de soja nas ra es. Os animais permaneceram no experimento até atingirem o peso final de 60,5 1,74 kg. Os níveis de lisina influenciaram de forma linear (P<0,01) crescente o ganho de peso diário (GPD), mas o modelo “Linear Response Plateau” (LRP) foi o que melhor se ajustou aos dados do GPD, estimando em 1,02% o nível a partir do qual ocorreu um plat . A convers o alimentar, o consumo de lisina diário e a deposi o de proteína diária aumentaram de forma linear em raz o dos níveis de lisina da ra o, que, no entanto, n o influenciaram o consumo de ra o diário. Concluiu-se que o nível de 1,02% de lisina digestível, correspondente a um consumo de 19,50 g/dia de lisina digestível (0,29%/Mcal de ED), proporciona os melhores resultados de desempenho e deposi o protéica em suínos mac

Abstract: Este estudo foi realizado com o objetivo de determinar a digestibilidade ileal, aparente e verdadeira, dos aminoácidos de alimentos, como: leite em pó, soro de leite, soja micronizada, soja extrusada e plasma suíno, comumente utilizados na formula o de dietas pré-iniciais para leit es, pela técnica do sacrifício. Foram utilizados 96 leit es mesti os com 40 dias de idade, distribuídos em delineamento inteiramente casualizado, com seis tratamentos, oito repeti es e dois animais por unidade experimental. As dietas foram formuladas para fornecer 7% de PB para o soro de leite e 13% para os demais alimentos, sendo o alimento avaliado a única fonte de proteína. Foi utilizada uma dieta isenta de proteína para determina o da perda endógena de aminoácidos. Os animais foram abatidos sete horas após a ingest o das dietas experimentais, sendo a digesta ileal coletada para forma o de uma amostra composta de digesta de oito animais, obtendo-se duas amostras por tratamento. Os maiores valores de digestibilidade verdadeira dos aminoácidos essenciais foram obtidos no soro de leite, leite em pó e soja extrusada, sendo os menores coeficientes de digestibilidade verdadeira encontrados na soja micronizada. A treonina foi o aminoácido essencial que apresentou menor coeficiente de digestibilidade verdadeira em todos os alimentos avaliados. A metionina foi o aminoácido que apresentou maior coeficiente de digestibilidade verdadeira no soro de leite, na soja extrusada, na soja micronizada e no plasma suíno, enquanto a lisina foi o de maior coeficiente de digestibilidade verdadeira no leite em pó. O menor coeficiente de digestibilidade da lisina foi obtido na soja micronizada.
