ABSTRACT This study evaluated the effect of detoxified castor meal on the reproductive performance, metabolic stress, milk production, and kid development in peripartum goats. The diet of the animals were with (DCM, n= 20) or without (WDCM, n= 21) detoxified castor meal during the entire gestation and until weaning, 60 days post-birth. No differences were observed in the gestation period, litter size, rate of multiple births, and mortality between the two groups. The postpartum plasma concentrations of progesterone remained below 1ng/mL in all animals, thus, confirming the absence of active corpora lutea. The thickness of sternum adipose tissue and loin area, levels of urea and cholesterol, milk production, and daily weight gain in the kids were low in the DCM group when compared to those in the WDCM group (P< 0.05). To conclude, the use of detoxified castor meal in peripartum goats resulted in lower level of performance in the kids because of reductions in the amount of milk received from their mothers during lactation. In addition, the diet containing detoxified castor meals was not efficient in recovering from the loss of stored body reserves able to initiate the recovery of the cyclic activity of the goats.

Sunscreens have been employed on daily skin care for centuries. Their role in protecting the skin from sun damage, avoiding accelerated photoaging and even limiting the risk of development of skin cancer is unquestionable. Although several chemical and physical filters are approved as sunscreens for human use, their safety profile is dependent on their concentration in the formulation which governs their acceptance by the regulatory agencies. A strategic delivery of such molecules should provide a UV protection and limit the skin penetration. Solid lipid nanoparticles (SLN) and nanostructured lipid carriers (NLC) may offer an alternative approach to achieve a synergistic effect on the UV protection when loaded with sunscreens as particles themselves also have a UV light scattering effect. Besides, the lipid character of SLN and NLC improves the encapsulation of lipophilic compounds, with enhanced loading capacity. Silica nanoparticles have also been employed in sunscreen formulations. Due to the formed sol-gel complexes, which covalently entrap sunscreen molecules, a controlled release is also achieved. In the present work, we have developed a new sunscreen formulation composed of hybrid SLN-Silica particles loaded with octyl methoxycinnamate (Parsol®MCX), and their further incorporation into a hydrogel for skin administration. Hybrid SLN-silica particles of 210.0 ± 3.341 nm of mean size, polydispersity below 0.3, zeta potential of ca. |7| mV, loading capacity of 19.9% and encapsulation efficiency of 98.3% have been produced. Despite the slight negative surface charge, the developed hybrid nanoparticles remained physicochemically stable over the study period. Turbiscan transmission profiles confirmed the colloidal stability of the formulations under stress conditions. The texture profile analysis of Parsol-SLN and Parsol-SLN-Si revealed semi-solid properties (e.g. adhesiveness, hardness, cohesiveness, springiness, gumminess, chewiness, resilience) suitable for topical application, together with the bioadhesiveness in the skin of pig ears. The non-irritation profile of the hybrid nanoparticles before and after dispersion into Carbopol hydrogels was confirmed by HET-CAM test.

Therapeutics. Pharmacology ,RM1-950 - Abstract
The reduction of the particle size of drugs of pharmaceutical interest down to the nano-sized range has dramatically changed their physicochemical properties. The greatest disadvantage of nanocrystals is their inherent instability, due to the risk of crystal growth. Thus, the selection of an appropriate stabilizer is crucial to obtain long-term physicochemically stable nanocrystals. High pressure homogenization has enormous advantages, including the possibility of scaling up, lack of organic solvents and the production of small particles diameter with low polydispersity index. The sequential use of high shear homogenization followed by high pressure homogenization, can modulate nanoparticles’ size for different administration routes. The present study focuses on the optimization of the production process of two formulations composed of different surfactants produced by High Shear Homogenization followed by hot High Pressure Homogenization. To build up the surface response charts, a 22 full factorial design experiment, based on 2 independent variables, was used to develop optimized formulations. The effects of the production process on the mean particle size and polydispersity index were evaluated. The best ibuprofen nanocrystal formulations were obtained using 0.20% Tween 80 and 1.20% PVP K30 (F1) and 0.20% Tween 80 and 1.20% Span 80 (F2). The estimation of the long-term stability of the aqueous suspensions of ibuprofen nanocrystals was studied using the LUMISizer. The calculated instability index suggests that F1 was more stable when stored at 4 °C and 22 °C, whereas F2 was shown to be more stable when freshly prepared.

Diseases of the respiratory system ,RC705-779 - Abstract
Sleep disturbance has been described in cystic fibrosis (CF) patients as relevant to clinical and lung function predictive factors helping to improve the diagnosis and early intervention. Related paediatric studies are scarce. Objective: To describe respiratory sleep disturbance (RSD) and its association with spirometric indices in a population of CF children. A second aim was to determine if spirometric indices and wake-time SpO2 are predictors of sleep disturbance. Methods: A cross-sectional study involving 33CF paediatric patients. All participants underwent in-lab polysomnography (PSG), pulse oximetry and spirometry. A standardized sleep questionnaire was completed for each patient. Two subgroups were considered: I â Normal (FEV1 > â1.64 z-score); II â Obstructed (FEV1 â¤Â â1.64 z-score). Results: Participant's median age was 12 (6â18) years, 16 (48.5%) were male. Twenty-nine patients (87.9%) presented sleep complaints. Sleep efficiency was reduced; sleep latency and waking after sleep onset (WASO) increased. N1 increased, N2, N3, REM and awakenings were normal. The apnoeaâhypopnoea index was 0.6/h (sd 0.9); respiratory disturbance index (RDI) was 6.6/h (sd 5.2). Mean awaking (97% (sd 1.1)) and sleep SpO2 (95% (sd 2.7)) were normal; mean nocturnal oximetry desaturation index was 2.36/h; minimal nocturnal SpO2 was 89% (sd 4.1).We found associations between mean nocturnal SPO2 and mean values of FEV1 (r = 0.528; p = 0.002) and FEF25â75 (r = 0.426; p = 0.013). There were significant differences in nocturnal SpO2 between normal and obstructed patients (pÂ

A expressão de RNAm para leptina, receptor de leptina (obRb), adiponectina, receptor de adiponectina (AdipoR1) e resistina foi avaliada por meio da técnica de PCR em tempo real, em tecidos ovariano, hipofisário, adiposo do omento e da região perirrenal, em ovelhas alimentadas sem farelo de mamona ou com farelo de mamona detoxificada durante 14 meses. O tipo de dieta não afetou os níveis de RNAm para leptina, obRb, adiponectina, AdipoR1 e resistina nos diferentes tecidos avaliados (P>0,05). Nos tecidos ovariano e hipofisário, não foi verificada a expressão da adiponecina e da resistina, respectivamente. Como consequência, pode-se concluir que o farelo de mamona detoxificada pode ser utilizado como fonte proteica na dieta de ovelhas, sem afetar a expressão do gene resistina e dos genes leptina e adiponectina, bem como de seus receptores.

Estudou-se a influência sazonal sobre a composição química, a contagem de células somáticas (CCS) e a contagem bacteriana total (CBT) de leite cru refrigerado em vários estados da região Nordeste. Os dados foram obtidos de 116.989 amostras de leite de tanques coletadas pelas indústrias com cadastro no serviço de inspeção federal. As amostras foram separadas em três períodos (I, II, III), de acordo com aplicação da Instrução Normativa-51 (IN-51). O teor de gordura, média de 3,7%, foi o componente do leite que apresentou maior variação. Proteína e lactose tiveram amplitude de 0,04% entre os períodos e apresentaram médias de 3,2 e 4,4%, respectivamente. Maiores valores de CCS foram observados entre os meses de maio e julho, 594,33 a 625,28 mil cel/mL, enquanto para CBT os maiores valores ocorreram nos meses de maio e junho, 1308,54 e 1333,83 UFC/mL. Observaram-se diferenças significativas nos componentes do leite entre os estados, principalmente no que se refere à qualidade higiênico-sanitária.

Diseases of the respiratory system ,RC705-779 - Abstract
Resumo: Introdução: A exposição ao fumo do tabaco (EFT) é factor de risco para Doença Pulmonar Obstrutiva Crónica e um problema major de saúde pública. A EFT pré e/ou pós-natal determina redução precoce da função pulmonar e aumento da morbilidade respiratória, dependente da dose. Tem sido sugerido que a EFT domiciliária é influenciada por factores socioeconómicos. Métodos: Estudo de rastreio epidemiológico transversal de dados de 313 crianças (52% rapazes) de 4 Escolas Básicas de Lisboa [1.° ano (54%) e 4.° ano]. A EFT e sintomatologia respiratória foram avaliadas a partir de questionário auto-preenchido pelos pais. Todas as crianças efectuaram espirometria na escola e 54% foram consideradas aceitáveis de acordo com critérios ATS/ERS. Efectuou-se análise descritiva e bivariada das variáveis com maior interesse e análise de regressão logÃstica múltipla ajustada para as variáveis com significado clÃnico/estatÃstico. Resultados: Em 41% dos casos a criança convivia com fumadores no domicÃlio (EFT na gravidez 18%, mãe fumadora 32%, pai fumador 38%). Os pais fumadores tinham escolaridade inferior e ocupações menos qualificadas. Tosse foi mais frequente nas crianças com mãe fumadora (OR ajustado = 2,1 95%CI 1,1â4,0) e sibilância nas crianças com EFT na gravidez e com mãe/pai fumadores. Todas as diferenças foram significativas (p <  0,05). Não se encontrou associação entre educação parental e sintomatologia respiratória ou ETF e infecções respiratórias/asma/diminuição de valores espirométricos. Conclusão: A EFT é frequente em crianças em idade escolar em Lisboa e condiciona morbilidade respiratória significativa. Intervenções dirigidas devem ter em conta condições sociais. Neste estudo a espirometria de campo foi pouco útil na detecção precoce de diminuição da função pulmonar em crianças associada à EFT. Abstract: Introduction: Tobacco smoke is a risk factor for Chronic Obstructive Pulmonary Disease and a major public health problem. Prenatal maternal smoking and post-natal environmental tobacco smoke (ETS) lead to dose-dependent decrease in lung function and respiratory morbidity. Influence of different socioeconomic indicators and ETS in the home has also been suggested. Methods: Data on 313 children (52% male) from 4 public schools in Lisbon was analyzed [1st (46%) and 4th graders]. ETS assessment and respiratory symptoms were based on a self-answered questionnaire. All children performed standard spirometry in the school setting and 54% were acceptable according to ATS/ERS criteria. Descriptive and bivariate analysis of the most relevant variables was done, followed by multiple logistic regression analysis adjusted to the variables with clinical/statistical relevance. Results: ETS in the home was found in 41% (maternal smoking during pregnancy 18%, smoking mother 32%, smoking father 38%). Smoking fathers had lower education and less qualified occupation. Cough was more frequent in children with a smoking mother (adjusted OR = 2.1 95CI 1.1â4.0) and wheezing in children with maternal smoking during pregnancy and smoking parents.

It is well known that the ventrolateral medulla contains neurons involved in the tonic and reflex control of the cardiovascular system. Two regions within the ventrolateral medulla were initially identified: the rostral ventrolateral medulla (RVLM) and the caudal ventrolateral medulla (CVLM). Activation of the RVLM raises arterial blood pressure and sympathetic nerve activity, and activation of the CVLM causes opposite effects. The RVLM premotor neurons project directly to sympathetic preganglionic neurons and are involved in the maintenance of resting sympathetic vasomotor tone. A significant proportion of tonic activity in the RVLM sympathetic premotor neurons is driven by neurons located in a third region of the ventrolateral medulla denominated caudal pressor area (CPA). The CPA is a pressor region located at the extreme caudal part of the ventrolateral medulla that appears to have an important role controlling the activity of RVLM neurons. In this brief review, we will address the importance of the ventrolateral medulla neurons for the generation of resting sympathetic tone related to arterial blood pressure control focusing on two regions, the RVLM and the CPA.

ABSTRACT: This study aimed to evaluate the efficiency and capacity of the probiotic composed of Bacillus subtilis and Bacillus amyloliquefaciens, in improving the zootechnical performance of broiler chickens challenged with Eimeria spp. and Clostridium perfringens. The broilers were distributed in a completely randomized design in poultry isolators (12 birds each), resulting in 3 treatments: T1 (control, no challenge and no Bacillus in diet), T2 (challenged with Eimeria spp., followed by Clostridium perfringens infection and no Bacillus in the diet), and T3 (challenged with Eimeria spp., Clostridium perfringens and treated with Bacillus subtilis and Bacillus amyloliquefaciens). They were evaluated for a period of 29 d, divided into preinitial (1–7 d of age), initial (8–21 d), and growth (22–29 d) phases. Assessments of body weight, weight gain, feed consumption, and feed conversion were conducted, along with the classification of the scores and optical microscopy of the tract gastrointestinal. The animals challenged and treated with the probiotic containing Bacillus spp. showed improved indicators of zootechnical performance. Additionally, the animals challenged and treated (T3) had a better score for intestinal lesions compared to the other treatment groups. Therefore, the probiotic consisting of Bacillus subtilis and Bacillus amyloliquefaciens could be considered an effective option for disease prevention and improving the zootechnical performance of broiler chickens

Micro(nano)plastics accumulate in natural environments worldwide, threatening biota, ecosystem functions, and services. In the last decade, there has been a substantial increase in the number of ecotoxicity studies to address the potential effects of micro(nano)plastics, including their plasticisers and adsorbed hazardous substances. Their environmental relevance has been under scrutiny due to the non-environmentally relevant testing conditions besides the lack of a proper characterization of the particles under study (e.g., size range, surface properties, crystallinity, chemical composition, including additives compounds), thus compromising the significance of the risk assessment and management strategies.This paper reviews the analytical methodologies applied in ecotoxicity tests for identifying, quantifying, and eventual characterising micro(nano)plastics before, during (monitoring), and after exposure, addressing their advantages and limitations. It also discusses emerging and cost-efficient methodologies that may speed up the detection and quantification of micro(nano)plastics and motivate their characterization for a deeper understanding of the underlying (eco)toxicity mechanisms.

RESUMO Objetivou-se relatar a utilização do neurolocalizador para bloqueio do plexo braquial bilateral em tamanduá-mirim (Tamandua tetradactyla). O animal, pesando 5kg, atendido pelo Centro de Reabilitação de Animais Silvestres, foi encaminhado ao Hospital Veterinário da Universidade Federal de Mato Grosso do Sul para realização de exames complementares, sendo, posteriormente, encaminhado para cirurgia de osteossíntese de úmero e rádio/ulna esquerdo e colocação de fio de cerclagem em olécrano direito. O paciente foi pré-medicado com cetamina S (5mg/kg) + midazolam (0,15mg/kg), indução anestésica com propofol (5mg/kg) e manutenção anestésica com isoflurano, com o auxílio de máscara. Os parâmetros cardiovasculares e respiratórios foram monitorados durante todo o procedimento. Realizou-se o bloqueio do plexo braquial em ambos os membros utilizando-se estimulador de nervos periféricos. Os anestésicos locais empregados foram lidocaína 2% sem vasoconstritor (3mg/kg) + ropivacaína 0,75% sem vasoconstritor (1mg/kg).

ABSTRACT Bovine tuberculosis is a worldwide spread zoonotic disease. Intradermal tuberculinizations are the most used diagnostic tests in the world. Serological tests can be an ancillary diagnosis for bovine tuberculosis. The objective of this study was to evaluate the diagnostic performance of the ELISA Mycobacterium Bovis Antibody Test Kit IDEXX ™ in infected herds, which were in different disease control stages. One hundred and twenty animals from two dairy herds of Minas Gerais state, Brazil, were subjected to the ELISA serological test and the comparative cervical tuberculin test (CCT). Diagnostic test parameters were estimated using Bayesian latent class models and concordance between tests estimated by the frequentist approach. The ELISA test presented lower sensitivity than CCT in both herds. Its sensitivity was higher in the herd in sanitation process. Specificity estimates were above 95% in both herds. Kappa index indicated low concordance or even disagreement between tests. According to the results, the ELISA IDEXX should not be used as substitution for CCT. The tests must not be associated in series. Parallel association increased diagnostic sensitivity in the herd which was in the process of sanitation.

Resumen Antecedentes La perdida de equilibrio en los adultos mayores es multifactorial y aumenta el riesgo de caidas en esta poblacion. Existen pruebas para evaluar el equilibrio, sin embargo, se centran en la evaluacion de una sola tarea, en entornos estaticos, sin considerar las demandas del control postural en situaciones de la vida cotidiana, como la interaccion de la persona con el contexto y las actividades multitarea. Objetivo Disenar y validar una prueba de equilibrio para adultos mayores con caracteristicas contextuales. Materiales y metodo Se desarrollo una metodologia de recoleccion de datos mixta, con un diseno metodologico exploratorio secuencial DEXPLOX derivativo de un diseno de triangulacion concurrente DITRIAC. Resultados Los resultados hallados en las primeras 3 fases permitieron construir los items de la prueba de evaluacion de equilibrio, luego se realizo la primera validacion de expertos, con un coeficiente kappa de Fleiss de 0,4 y una validez de contenido de Lawshe de 0,95. La segunda validacion por expertos dio como resultado en la validez facial una fuerza de concordancia interevaluadores excelente y una validez de contenido de Lawshe en relevancia de 0,95 y en pertinencia de 0,97. Conclusiones La prueba disenada ha demostrado caracteristicas de validez fuertes y puede ser aplicada en adultos mayores, pues se incluyen items que exigen respuestas somatosensoriales, como las que se realizan en las actividades de la vida diaria e items con actividades de doble tarea cognitivas en el contexto real.

The goal is to present a descriptive study related an unprecedent case of spinal myoclonus (SM) following subarachnoid anesthesia (SA). SM are sudden, brief, involuntary non-generalized spasms that can be an adverse effect of drug administration via neuraxial routes. Female, 67y, ASA II, proposed for hip replacement surgery, with normal preoperative exams. 7min after SA with 10mg of bupivacaine 0,5%, no motor blockade observed, and patient complained of unbearable pain in legs and perineum and bilateral, asymmetrical and arrhythmic myoclonic movements in the lower limbs. The latter solved after 48h of general anesthesia and rocuronium perfusion, amongst other therapeutics. Accordingly, intrathecal bupivacaine appears to be the SM most likely cause, regarding the absence of neurologic and electrolyte disorders, spinal cord direct trauma, drug exchange and normal perioperative examination, imaging and laboratory testing.It is mandatory to always take the patients' anaesthetic histories and recognize, treat and report rare anaesthetic complications.

The aim of this study was to evaluate the effects of different light colors on growth, pigment composition, and photosynthetic performance of Arthrospira platensis. Results showed that under orange light the biomass productivity increased due to the capability of A. platensis to fully absorb this portion of the light spectrum. Under blue light, phycocyanin increased continuously up to 13.2% +/- 1.96 of dry weight at day 5, while under orange and white lights the phycocyanin content resulted lower, 7.1 +/- 0.39 and 6.7% +/- 1.58 of dry weight, respectively. Chlorophyll fluorescence measurements showed the maximum electron transport rate (rETR(max)) in cells grown under orange light. The results of this study indicated that the orange light increased both growth and phycocyanin productivities, while blue light increased mostly the phycocyanin content, while biomass productivity was much lower. Further increase of phycocyanin content was observed shifting the light illuminating the cultures from orange to blue, attaining a raise in phycocyanin content from 8.6% to 12.5% of dry weight within 48 h from the start of the illumination with blue light. Within the same period of time no growth was observed indicating that the synthesis of phycocyanin can be decoupled from growth. This study provides useful physiological information regarding the effects of different light spectra on growth, phycocyanin, and photosynthetic performance, as a prerequisite to optimize the production of high value pigments from cultures of A. platensis.

From 1985 to 2016, the prevalence of underweight decreased, and that of obesity and severe obesity increased, in most regions, with significant variation in the magnitude of these changes across regions. We investigated how much change in mean body mass index (BMI) explains changes in the prevalence of underweight, obesity, and severe obesity in different regions using data from 2896 population-based studies with 187 million participants. Changes in the prevalence of underweight and total obesity, and to a lesser extent severe obesity, are largely driven by shifts in the distribution of BMI, with smaller contributions from changes in the shape of the distribution. In East and Southeast Asia and sub-Saharan Africa, the underweight tail of the BMI distribution was left behind as the distribution shifted. There is a need for policies that address all forms of malnutrition by making healthy foods accessible and affordable, while restricting unhealthy foods through fiscal and regulatory restrictions. © Copyright.

Background: Diagnosis of paradoxical tuberculosis-associated immune reconstitution inflammatory syndrome (TB-IRIS) is challenging and new tools are needed for early diagnosis as well as to understand the biochemical events that underlie the pathology in TB-IRIS. Methods: Plasma samples were obtained from participants from a randomized HIV/TB treatment strategy study (AIDS Clinical Trials Group [ACTG] A5221) with (n = 26) and without TB-IRIS (n = 22) for an untargeted metabolomics pilot study by liquid-chromatography mass spectrometry. The metabolic profile of these participants was compared at the study entry and as close to the diagnosis of TB-IRIS as possible (TB-IRIS window). Molecular features with p

This trial was carried out with the objective to evaluate the effect of feeding dried carnauba wax palm fruit on the quality of goat meat. Initially, the animals were divided into two groups: a control group, fed with ground corn-based concentrate, and a treatment group, fed with dried carnauba wax palm fruit included in the concentrate. After 28 days of feeding, the animals were slaughtered, and different muscles (Longissimus lumborum and semimembranosus) were evaluated for physicochemical characteristics, fatty acid profile, and expression of some genes related to meat quality. The diet with carnauba wax palm fruit does not interfere in the chemical composition of the meat in terms of moisture content, protein, fat, pH, and meat color. On the other hand, palmitic (C16:0) and linoleic (C18:2) fatty acids presented differences between muscles in the group fed carnauba wax palm fruit. The treatment with carnauba wax palm fruit reduces the expression of genes related to lipogenesis and cholesterol metabolism, suggesting the production of a tender meat with lower cholesterol content. The inclusion of carnauba wax palm fruit in the diet of does maintained the physicochemical characteristics of the loin and leg, and it reduced the expression of the analyzed genes, suggesting improvement in meat quality.

Several high-value microalgal products have become well established, and there are opportunities for additional new ones. Microalgae are also playing an increasing role in cosmeceuticals, nutraceuticals, and functional foods. In this chapter the effects of the main environmental factors on the productivity and biochemical composition of microalgal biomass are summarized. Particular emphasis has been devoted to the environmental factors limiting the full exploitation of the photosynthetic capacity of the cultures. Among these, light saturation remains the main obstacle to economical exploitation of microalgae production potential. Other important limiting environmental factors are represented by sub- and supraoptimal temperatures. The effects of environmental factors on productivity are further enhanced when they act in synergy. The opportunity to improve light utilization by increasing the mixing rate and the effective possibility to take advantage of intermittent light are discussed in detail in relation to the culture system. Independently of the strain to be produced, the overall production system must be approved for the “food industry”; this regulatory compliance involves the materials, systems, and protocols used during production. These aspects are reviewed in the final part of the chapter.

Guidelines on follow-up of children with post-infectious bronchiolitis obliterans(PIBO) and/or bronchiectasis(BE) are scarce. Orientations are derived from other chronic lung diseases and adult studies. Aim: describe the management plan of children with PIBO and/or BE and analyse if it varies with lung function(LF). Methods: Retrospective review of medical records of children with PIBO and BE followed in a tertiary hospital for 2consecutive years(2018-9). Diagnosis based on history, LF and HRCT findings. Frequency of physician visits, spirometries and respiratory microbiology surveillance/year were recorded, as best LF parameters and nutritional status/year.Descriptive and regression analysis was done. Results: During the study period, 28 children [20 boys, median age 13.5yrs (7.1, 18.2), median duration of follow-up 9.6yrs(2.5, 15.4)], 16 with BOPI (plus BE 6; average z-score BMI -0.7, FEV1 -3.2, FEV1/FVC -2.6) and 12 with BE (average z-score BMI 0.4, FEV1 -0.5, FEV1/FVC -0.1) were regularly observed, on average, 2.7times/year (1 to 7) and performed 1.8spirometries/year (1 to 4) but only 4 had respiratory samples collected. 14 had been prescribed mucus clearance devices or educated on respiratory rehabilitation. No association between clinic visits and FEV1 was found. During this period,3 non-residents in Portugal were also observed,7 initiated follow-up and 10 were transferred/lost to follow-up. Method: Respiratory microbiology surveillance was low. In this small sample, LF alone did not instruct on follow-up. In the absence of guidelines, management is tailored to patients. Future directions should dictate minimal follow-up requirements for children with BOPI and BE.

The changes in host lipid metabolism during leprosy have been correlated to fatty acid alterations in serum and with high-density lipoprotein (HDL) dysfunctionality. This is most evident in multibacillary leprosy patients (Mb), who present an accumulation of host lipids in Schwann cells and macrophages. This accumulation in host peripheral tissues should be withdrawn by HDL, but it is unclear why this lipoprotein from Mb patients loses this function. To investigate HDL metabolism changes during the course of leprosy, HDL composition and functionality of Mb, Pb patients (paucibacillary) pre- or post-multidrug therapy (MDT) and HC (healthy controls) were analyzed. Mb pre-MDT patients presented lower levels of HDL-cholesterol compared to HC. Moreover, Ultra Performance Liquid Chromatography-Mass Spectrometry lipidomics of HDL showed an altered lipid profile of Mb pre-MDT compared to HC and Pb patients. In functional tests, HDL from Mb pre-MDT patients showed impaired anti-inflammatory and anti-oxidative stress activities and a lower cholesterol acceptor capacity compared to other groups. Mb pre-MDT showed lower concentrations of ApoA-I (apolipoprotein A-I), the major HDL protein, when compared to HC, with a post-MDT recovery. Changes in ApoA-I expression could also be observed in M. leprae-infected hepatic cells. The presence of bacilli in the liver of a Mb patient, along with cell damage, indicated hepatic involvement during leprosy, which may reflect on ApoA-I expression. Together, altered compositional and functional profiles observed on HDL of Mb patients can explain metabolic and physiological changes observed in Mb leprosy, contributing to a better understanding of its pathogenesis., Author summary Leprosy is a chronic disease caused by Mycobacterium leprae, which causes lesions on the skin and peripheral nerves. Some patients do not present an efficient immune response and have a disseminated infection (multibacillary, Mb). Mb patients have lipid accumulation in infected tissues that is important for microorganism survival. High-density lipoprotein (HDL) is composed of proteins and lipids and is produced in the liver. It removes excess of lipids from peripheral tissues and presents anti-inflammatory activity; however, these activities are not being properly performed in leprosy. To understand more about HDL metabolism on leprosy, the chemical composition and functionality of HDL from leprosy patients were analyzed before and after treatment with antibiotics (multidrug therapy, MDT). It was observed that HDL has an altered lipid composition in Mb patients before MDT, which may lead to an impairment of its functions. Apolipoprotein A-I (ApoA-I), the main HDL protein, seems to be highly affected during infection. These functions can be slightly recovered after MDT, but not in the levels of healthy individuals. Our data open new perspectives to elucidate the modulation of lipid metabolism in leprosy and consequently to prevent disease complications.

Purpose Abdominal hysterectomy is one of the most commonly performed gynecologic surgical procedures and is frequently associated with moderate to severe pain. The present study compared the effects of morphine and ketamine on postoperative analgesia, hemodynamic stability, and postoperative adverse effects in patients who underwent abdominal hysterectomy. Design This randomized controlled trial compares the effects of morphine plus adjuvants to those of ketamine plus adjuvants, administered as spinal anesthetic agents in patients who underwent abdominal hysterectomy. Methods Eighty patients were randomly assigned to two different groups: group M (morphine, 40 mcg) and group K (ketamine, 20 mg); the anesthetic agents were combined with equal quantities of other adjuvants. Postoperative analgesia was evaluated by means of a numeric pain rating scale; adverse effects (pruritus, nausea and vomiting, urinary retention, respiratory depression, and changes in bowel habits) at specific postoperative time intervals of T1 (4 hours), T2 (12 hours), and T3 (24 hours) were documented and compared. Hemodynamic stability was assessed intraoperatively. Findings Both groups displayed similar patient characteristics, comorbidities, paravertebral block level, and intraoperative hemodynamics. The present study observed a significant difference in postoperative analgesia between the two groups, 12 hours after the surgery, with group M exhibiting better results, compared with group K (P = .004). The pain scores obtained from group K were consistent with the amount of rescue medication (tramadol) administered to the subjects in the group, which showed a concomitant higher consumption of tramadol, compared with group M (42.5 and 71.8 mg in group M and group K, respectively, P = .011). Group M showed a higher incidence of pruritus, changes in bowel habits, and constipation compared with group K. Conclusions Compared with ketamine, intrathecal morphine obtained better postoperative analgesia up to 12 hours after surgery, with a higher incidence of pruritus without any significant change in other variables.

This study evaluated the effect of detoxified castor meal on the reproductive performance, metabolic stress, milk production, and kid development in peripartum goats. The diet of the animals were with (DCM, n= 20) or without (WDCM, n= 21) detoxified castor meal during the entire gestation and until weaning, 60 days post-birth. No differences were observed in the gestation period, litter size, rate of multiple births, and mortality between the two groups. The postpartum plasma concentrations of progesterone remained below 1ng/mL in all animals, thus, confirming the absence of active corpora lutea. The thickness of sternum adipose tissue and loin area, levels of urea and cholesterol, milk production, and daily weight gain in the kids were low in the DCM group when compared to those in the WDCM group (P< 0.05). To conclude, the use of detoxified castor meal in peripartum goats resulted in lower level of performance in the kids because of reductions in the amount of milk received from their mothers during lactation. In addition, the diet containing detoxified castor meals was not efficient in recovering from the loss of stored body reserves able to initiate the recovery of the cyclic activity of the goats.

In this paper we propose to study the cross-correlation between the air temperature and the air relative humidity using the DCCA cross-correlation coefficient ρ D C C A . We choose four cities (meteorological stations) located in the State of Bahia (Brazil), as our case study. Our data were available hourly from the Brazilian Institute of Meteorology. Accordingly, in addition to showing that the variables have a negative cross-correlation, we present a new vision about these variables, producing the detrended cross-correlation contour map. As a result, we can see (or not) islands of cross-correlations, that depend on the local time and also the time scale involved.

In vitro culture of ovarian preantral follicles has emerged as a reproductive technology aimed at obtaining large amount of oocytes for in vitro embryo production. The addition of growth factors (GF) in the in vitro culture of preantral follicles of different species has provided superior results of follicular development, antrum formation and proliferation of granulosa cells. However, there are only few reports regarding the use of these factors on feline preantral follicle in vitro culture. Thus, the aim of this study was to investigate the effect of a combination of IGF-1 and EGF on in vitro viability and growth of preantral follicles and enclosed oocytes collected from domestic cats. A total of 64 follicles characterized by multilayer granulosa cells were isolated and individually cultured for 6 days (T6) in minimum essential medium supplemented with IGF-1+ EGF (100 ng/ml each) or without (control). A higher percentage of follicles were viable after culture with GF than without, and an increase in size when IGF-1+ EGF were added to the medium (170 ± 32.4 μm (T0) vs. 201 ± 22.3 μm (T6); p .05) was observed. An increase in the diameter was also observed in follicles cultured without GF, but this increase was only 8.3% compared to 15.4% of those cultured with GF (p .05). No differences were found in the diameter of oocytes contained in follicles cultured in the non-supplemented or supplemented media (107.9 ± 11.8 μm (T0) vs. 113.2 ± 15.6 μm (T6); p .05). These data suggest that the addition of IGF-1 and EGF to the culture medium promotes the in vitro development of preantral follicles of cats.

Bioleaching is a mature technology, which is widely employed commercially in the leaching of low-grade secondary copper sulphide ores. In this work, the bioleaching potential of a low-grade (marginal) ore with a significant content of fluoride was assessed. Small columns were inoculated with a strain of At. ferrooxidans, at 30 °C, and resulted in copper extractions above 89%, in 255 days. The dissolution of fluorite from the gangue minerals accounted for up to 2.5 g/L fluoride in solution, which affected bioleaching shortly after column inoculation. However, both the released of aluminium from the ore and ferric iron production by the bacteria reduced fluoride toxicity. A fluoride-toxicity parameter (η) was proposed to represent the mass ratio between total fluoride, total aluminium and total ferric iron concentrations in the system. Low values of the η parameter resulted from high ferric iron and aluminium concentrations and implied in large bacterial population in the systems. Thus, the presence of fluoride-bearing minerals in the ore may be an important issue, but the content of both cations should be also considered. Despite the absence of ferric iron and a high fluoride concentration prior to first solution bleeding, the η parameter was lower than 0.3 in the column containing an external aluminium source. In this condition, as the aluminium content surpassed that of fluoride the bacterial population reached 107 cells/mL and enabled copper bioleaching.

RESUMO A biolixiviação de minérios de baixo teor e com elevado conteúdo de impurezas tem se mostrado alternativa importante para o aproveitamento destes, uma vez que a recuperação do metal por métodos pirometalúrgicos convencionais mostra-se economicamente inviável. A identificação e quantificação dos micro-organismos capazes de promover a biolixiviação mostram-se estratégicas para alcançar bons rendimentos no controle do processo e na recuperação de metais. Nesse sentido, as técnicas de biologia molecular são as ferramentas mais utilizadas para tal propósito. Este trabalho, utilizando técnicas de reação em cadeia da polimerase (PCR), polimorfismos de comprimento dos fragmentos de restrição (RFLP) e reação em cadeia da polimerase seguida de eletroforese em gel com gradiente desnaturante (PCR-DGGE), mostrou que a diversidade nas colunas de biolixiviação de cobre estudadas é baixa e que a temperatura é importante na manutenção de determinadas espécies, havendo predominância de Acidithiobacillus ferroxidans a 35°C e de Sulfobacillus thermosulfidooxidans a 50°C. ABSTRACT Bioleaching is an alternative to pyrometallurgy for the production of metals from low-grade ores containing high level of impurities, once that live pyrometallurgical methods are economically unfeasible. The quantification and identification of those microorganisms related to bioleaching is an important strategy for process control and thus metal recovery. In this regard, molecular biology is one of the main techniques utilized for such objective. This study applied PCR, RFLP and PCR-DGGE techniques to show that the microbial diversity in copper bioleaching columns under investigation is low and the temperature is important to define the species found, with predominance of Acidithiobacillus ferroxidans, at 35°C and Sulfobacillus thermosulfidooxidans at 50°C.
