Kommunikáció az egészségügyi teamen belül: orvosok és szakdolgozók
Authors: Kollár János
Published: April 2016

Proper communication within the health care team is especially important in terms of creating safe emotional and professional conditions for the team members and for quality healing. The aim of the study is to explore the factors that hinder appropriate communication between doctors and nurses and thus to make the effective elimination of the communication disturbances possible. Investigation in main medical databases and general search engines were used for analysing the phenomenon. It was revealed that communication between doctors and nurses is restrained by factors that can be observed on individual, professional and system levels as well. Role confusion, lack of trust, communication barriers arising from hierarchical inequalities, leadership problems, differences in qualifications, burnout and organizational problems can equally be found amongst them. The effectiveness of communication between nurses and doctors in Hungary is especially strongly influenced by the fear of losing jobs, the financial problems arising from different degree of gratuity and the phenomenon of burnout. Changes on individual, professional and system levels are equally important for significant improvement in the communication between doctors and nurses. Joint trainings based on strong organizational development skills and joint conferences could promote significantly better flow of information, mutual appreciation and harmonization. Orv. Hetil., 2016, 157(17), 659–663.
Tévhitek az orvosi kommunikációról
Authors: Sándor Imola , Pilling János
Published: April 2016

Despite a growing body of evidence about the importance of good communication skills in healthcare, every day practice shows several common myths or false believes about it. In the opinion of the authors these misbelieves are often behind doctors’ or students’ negative attitudes, which hinder the quality improvement or shift towards patient-centered approach. The scope of this article is to present the most frequently heard misbelieves from our empirical experiences in line with the evidence derived from current research data. Orv.

Az internet hatása az orvos–beteg viszonyra
Authors: Gaal Ilona
Published: April 2016

Internet became an inevitable phenomenon in the physician–patient relationship. The author analyzes it in two theoretical models: the effects on the medical profession and the interference with the decision making process. These will help to explain why patients search the internet for information about their illness, cure and their doctors. Some physicians dislike this, and they are not just worried about the patient, but about their own position and time. This fear is groundless, even if the internet patient can be hard to tackle in the daily routine. Internet can be seen not only as a necessary evil, but with proper communication skills physicians can benefit from their patients’ passion to internet. Orv. Hetil., 2016, 157(17), 680–684.
A kommunikáció és az önrendelkezés javításának lehetőségei az életvégi döntések meghozatalánál az intenzív osztályokon
Authors: Zubek László
Published: April 2016

The end-of-life decision making process normally based on patient autonomy or substituted judgement. If the patient can express his/her wishes, one must take note of his autonomy. If he/she is unable to self-determination, the importance of advanced directives or substituted judgement increases in the field of end-of-life care. The most important target of the efforts is to improve end-of-life care at intensive care units. Based on bioethical studies of the author and international literature this paper analizes the practice of end-of-life care and presents recommendations for lawmakers. The author proposes to divide patients with organ failure into three parts (end-of-life triage). The first part includes definitely salvageable, the second part definitely unsalvageable, and the third part possibly salvageable groups. This classification depends on the development of medical science and the local options of medical treatment. The quality of the decision-making process can be improved, but all participants must participate and medio-legal regulation must be improved. Orv. Hetil., 2016, 157(17), 669–674.
Liolaemus riodamas Esquerré, Núñez & Scolaro, 2013 (Reptilia: Squamata: Liolaemidae): new record for the Maule Region in Chile
Authors: Esquerré Damien , Troncoso-Palacios Jaime , Barros Rodrigo
Published: April 2016

Liolaemus riodamas is a recently described lizard, only known from a very restricted river canyon in the Andes of the O’Higgins Region in Chile. The species is particular for being one of the few Liolaemus lacking the pheromone secreting glands known as precloacal pores. Here we document a second locality for this species located 30 km southwest of the type locality. This is also 500 m higher than the type locality, therefore a considerable altitudinal extension. This is a very positive discovery since the type locality of L. riodamas is intervened by a hydroelectric project, and gives hope to the conservation of this unique taxon.
EDUCATION IN TIMES NET GENERATION: HOW DIGITAL IMMIGRANTS CAN TEACH DIGITAL NATIVES
Authors: Chaves Hamilton Viana , Maia Filho Osterne Nonato , Melo Armando Sérgio Emerenciano de
Published: April 2016

Members of the knowledge society, of the network society or of the informatics society are some names that seem to define the current generation. Net generation is a generic nomenclature which covers all the previous terms. Digital immigrants are the subjects whom were born before the advent of digital technologies and who joined to them. Digital natives are the subjects whom were born in the current generation and that would have special qualities, especially regarding the learning process. Considering all this context, a question arises: how the digital immigrants teach the digital natives? This item justifies itself because there is a meeting of generations, in theory, significantly differentiated. Due to this, it would be necessary to identify the appropriate educational forms according to the presented situation. Our teaching experience convinces us that, yes, we should valorize the information’s technologies and communication, understanding that these are means, not ends. It is important to highlight that any tool causes advances and regressions, a fact that serves to guide our teaching practice.
CONICAL HOPPER DESIGN FOR MASS FLOW – CASE OF RED MUD
Authors: Lobato Júlio César Mendes , Mascarenhas Fernando Pereira , Mesquita Alexandre Luiz Amarante , Mesquita André Luiz Amarante
Published: April 2016

Problemas em silos podem ocorrer, em muitos casos, devido ao incorreto dimensionamento de sua geometria por não considerar as propriedades de fluxo do material granulado. Um dos fatores que afetam as propriedades de fluxo do material é a umidade, que favorece a formação de arcos coesivos no material no interior do silo impedindo o fluxo mássico desejado. Portanto, este artigo objetivou analisar as propriedades de fluxo da lama vermelha, para diferentes teores de umidade, com o intuito de dimensionar a tremonha cônica de silos para fornecer um fluxo mássico do material. Inicialmente, as propriedades de fluxo da lama vermelha foram obtidas em laboratório utilizando o Célula de Cisalhamento Tipo Jenike e em seguida o dimensionamento da tremonha do silo foi realizado usando as teorias de Jenike e Enstad, ou seja, o diâmetro mínimo de descarga e o ângulo de inclinação foram determinados para cada teor de umidade. Ensaios em laboratórios usando silos de acrílicos com diferentes tremonhas foram realizados e os resultados experimentais apresentaram boa concordância com os resultados teóricos.

Authors: Sevastianov V. I. , Popov V. K. , Belov V. Yu. , Kursakov S. V. , Antonov E. N. , Bogorodsky S. E.
Published: April 2016

Aim.The development of a prolonged form of acetylsalicylic acid (ASA) encapsulated into polymeric highly porous microcarriers using supercritical carbon dioxide and the subsequent study of ASA release kinetics in vitro and in vivo using high-performance liquid chromatographic (HPLC).

Materials and methods.As polymeric carriers for ASA encapsulation amorphous D,L-polylactides (PLA) and polylactoglycolides (PLGA) of PURASORB PDL02 and PDLG7502 series (PURAC Biochem BV, Netherlands) were selected. The ASA encapsulation was performed using the PGSS (Particles from Gas Saturated Solutions) method of supercritical fl uid formation of microfi ne (20–50 μm) bioresorbable powders of aliphatic polyethers containing 10 wt.% ASA. The release kinetics of ASA from polymeric microparticles into saline solution as well as pharmacokinetic studies in vivo (rabbits) were registered by HPLC.

Results.A method of quantitative determination of ASA and its main metabolite salicylic acid (SA) in model solution and blood plasma by HPLC-UV detection with enhanced sample preparation and selectivity was developed. The method’s analytical range without accounting for dilution was 0.05–5.0 μg/ml for model solution and 0.2–10.0 μg/ml for blood plasma; the degree of extraction of ASA SA from blood plasma – 95.8 and 98.1%, respectively. It was demonstrated that the amount of ASA released from PLA during the fi rst 4 h exceeds the mass of ASA released from PLGA by approximately 25% which may serve as a justifi cation for the selection of PLGA as a carrier for the creation of a prolonged form of ASA. Pharmacokinetic studies (rabbits, n = 3) demonstrated a gradual release of ASA from PLGA microparticles during 24 h after intramuscular implantation of encapsulated form of ASA at the dose of 10 mg/kg.

Conclusion.Test samples of highly porous microfi ne powders of PLGA obtained by PGSS containing up to 10 wt.% ASA may serve as source prototypes for the development and creation on their basis of a prolonged form of ASA.

Aim.The main aim of our research is to evaluate the process of rat lung decellularization and recellularization as the initial step of tissue-engineered organs creation.

Materials and methods.Rat lung decellularization was performed by perfusion with detergents and enzymes with concomitant atmospheric air ventilation through the trachea. The quality of decellularization was analyzed with routine histological and immunohistochemical staining techniques, DNA content was determined quantitatively by spectrophotometer. For static and whole organ reseeding as a model of cells’ behavior mesenchymal multipotent stromal cells were used. Recellularization was followed by assessment of the cellular metabolic activity by colorimetric method; cell viability was analyzed by calcein and ethidium homodimer staining. Matrix qualitative evaluation after recellularization was performed using immunohistochemical staining methods.

Results.92% of allogeneic DNA was eliminated after decellularization. Histological staining revealed no residual cells and cell nuclei; preservation of the fibers of extracellular matrix was confirmed by immunohistochemical staining for laminin, elastin, fibronectin, collagen types I and IV before and after decellularization. The scaffold does not exhibit toxic properties after reseeding; cell viability and metabolic activity were proved after cultivation.

Conclusion.The experience of rat lung decellularization and recellularization can be the prospective basis for protocols of organ recellularization and tissue engineered lungs creation.

Published: April 2016

Aim:to study of infl uence of various doses of autologous BM MSCs on the development of chronic transplant nephropathy in a decentralized kidney using kidney autotransplantation model (KAT).

Materials and methods.Five groups of experiments were performed on 105 Wistar rats. The model of kidney autotransplantation by means of surgical decentralization (denervation – delymphatization) and infl ammation induction with kidney antigen and Freund’s adjuvant was created in groups I, II and III. Group I served as a decentralization control (control 1). In groups II and III autologous BM MSCs were injected intravenously once 35–40 days after surgery – a high dose in group II: 3.0–5.0×106 cells; a low dose in group III: 0.3–0.5×106 cells; group IV served as intact control; group V served as intact control with the injection of the same dose of BM MSCs as in group II. Kidney excretory functions (diuresis, creatinine, urea, protein in blood and urine, sodium excretion) and morphology were examined during months 3, 5 and 7–10.

Results.In all five groups over the study duration nitrogen excretion was not disrupted. High doses of BM MSCs after KAT modeling resulted after month 3 in pronounced proteinuria in all rats (3–3.5 times more than in group I) and gradually decreased diuresis; histologically severe focal cell infiltration and the accumulation of protein masses in lumina of glomeruli and tubules were observed. By month 10 glomerular and tubulointerstitial focal sclerosis was developed. Low doses of BM MSCs after KAT modeling led to gradual decrease of proteinuria after month 3 reaching the initial values by months 5 and 7 of observation; histologically rare foci of cellular infiltration around glomeruli were observed.

Conclusion.A single application of low doses of BM MSCs is capable of protective desensitizing infl uence on the tissue of decentralized kidney and can prolong the duration of kidney function without signs of pronounced damage, while under the same conditions high doses of autologous BM MSCs lead to accelerated development of severe chronic transplant nephropathy.

COMBINED HEART-KIDNEY TRANSPLANTATION
Authors: Poptsov V. N.
Published: April 2016

Combined heart-kidney transplantation may be performed in carefully selected patients with end-stage heart disease and renal failure. There are two types of combined transplantation of heart and kidney: 1) simultaneous heart-kidney transplantation (SHKT) from the same donor; 2) staged transplantation of heart and kidneys from two genetically different donors. The ISHLT registry in 2014 reported an increase in the number of SHKT over the years: from 22 in 1994 to 97 in 2012. World experience demonstrated excellent results of SHKT. Recipients of SHKT had superior survival, lower rates of acute cardiac and renal rejection compared to heart recipients. This article discusses the indications for simultaneous or staged heart-kidney transplantation in patients with dialysis-independent or dialysis-dependent renal failure, results and posttransplant survival of SHKT recipients. The author describes his own experience of 2 staged combined heart-kidney transplantations.

Published: April 2016

ABSTRACT Paraclinoid aneurysms are lesions located adjacent to the clinoid and ophthalmic segments of the internal carotid artery. In recent years, flow diverter stents have been introduced as a better endovascular technique for treatment of these aneurysms. Method From 2009 to 2014, a total of 43 paraclinoid aneurysms in 43 patients were surgically clipped. We retrospectively reviewed the records of these patients to analyze clinical outcomes. Results Twenty-six aneurysms (60.5%) were ophthalmic artery aneurysms, while 17 were superior hypophyseal artery aneurysms (39.5%). The extradural approach to the clinoid process was used to clip these aneurysms. One hundred percent of aneurysms were clipped (complete exclusion in 100% on follow-up angiography). The length of follow-up ranged from 1 to 60 months (mean, 29.82 months). Conclusion Surgical clipping continues to be a good option for the treatment of paraclinoid aneurysms.

ABSTRACT Studies which have investigated muscular performance during the initial stages of Parkinson´s disease (PD) without L-dopa treatments were not found. Objective to assess whether muscular performance, work and power, of the trunk and lower limbs in L-dopa naïve patients in the early stages of PD was lower than those of healthy subjects and to compare muscular performance between the lower limbs. Method Ten subjects with PD, Hoehn and Yahr (HY) I-II, L-dopa naïve and 10 subjects in the control group were assessed with the isokinetic dynamometer. Results ANOVAs revealed that work and power measures of the trunk, hip, knee, and ankle muscular groups were lower in PD compared with the control group (p < 0.05). There were no significant differences in muscular performance between the lower limbs. Conclusion The results suggested the use of specific exercises, as rehabilitation strategies, to improve the ability to produce work and power with this population.

Published: April 2016

ABSTRACT The Neurological Fatigue Index for Multiple Sclerosis (NFI-MS) is a new fatigue assessment instrument. The aim of this study was to cross-culturally adapt and assess the psychometric properties of the Brazilian version of the NFI-MS (NFI-MS/BR). Method Two hundred and forty subjects with MS were recruited for this study. The adaptation of the NFI-MS was performed by translation and back translation methodology. In psychometric analysis was performed the administration of the questionnaires Epworth Sleep Scale, Fatigue Severity Scale, Modified Fatigue Impact Scale, Multiple Sclerosis Impact Scale-29, NFI-MS/BR and Pittsburgh Sleep Quality Index with retest of the NFI-MS/BR after 7 days. Results Reliability was assessed (intraclass correlation coefficients between 0.77 and 0.86), and validity by testing 41 hypotheses about expected correlations between subscales and confirmed 36. The majority of correlations were demonstrated. Conclusion The NFI-MS/BR is a cross-culturally adapted, valid, and reliable instrument for assessing MS fatigue among Brazilian subjects.

ABSTRACT Objective To assess the neurodevelopmental functions of survivors of twin-twin transfusion syndrome (TTTS) treated by fetoscopic laser coagulation (FLC), during the first year of life, comparing them to a control group; and to verify the influence of specific variables on neurodevelopment. Method This was a prospective, longitudinal study. The sample comprised 33 monochorionic diamniotic twins who underwent FLC for treatment of TTTS and 22 full-term infants of single-fetus pregnancies. Bayley Scales of Infant and Toddler Development Screening Test were used for evaluation. Prenatal, perinatal and postnatal information were obtained. Results There was an increased frequency of infants in the TTTS group with inadequate performance compared to the control group. The identified variables (fetal donor, low economic income and cardiorespiratory disease) negatively impacted expressive communication and fine motor skills. Conclusion Although through follow-up is recommended in all TTTS survivors, particular attention is required for the high-risk group as defined in this study.
Cerebrospinal fluid data compilation and knowledge-based interpretation of bacterial, viral, parasitic, oncological, chronic inflammatory and demyelinating diseases. Diagnostic patterns not to be missed in neurology and psychiatry
Authors: Reiber Hansotto
Published: April 2016

ABSTRACT The analysis of intrathecal IgG, IgA and IgM synthesis in cerebrospinal fluid (CSF) and evaluation in combined quotient diagrams provides disease-related patterns. The compilation with complementary parameters (barrier function, i.e., CSF flow rate, cytology, lactate, antibodies) in a cumulative CSF data report allows a knowledge-based interpretation and provides analytical and medical plausibility for the quality assessment in CSF laboratories. The diagnostic relevance is described for neurological and psychiatric diseases, for which CSF analysis can’t be replaced by other diagnostic methods without loss of information. Dominance of intrathecal IgM, IgA or three class immune responses give a systematic approach for Facial nerve palsy, Neurotrypanosomiasis, Opportunistic diseases, lymphoma, Neurotuberculosis, Adrenoleucodystrophy or tumor metastases. Particular applications consider the diagnostic power of the polyspecific antibody response (MRZ-antibodies) in multiple sclerosis, a CSF-related systematic view on differential diagnostic of psychiatric diseases and the dynamics of brain- derived compared to blood-derived molecules in CSF for localization of paracytes.

Published: April 2016

ABSTRACT: The goal of the present study was to evaluate the germination, initial growth, and in vitro co-cultivation of Comanthera curralensis Moldenke, a "sempre viva" native of the Chapada Diamantina state of Bahia. Full strength (MS) and half-strength MS (MS1/2) growth media supplemented with two different sucrose concentrations (15 and 30g L-1) were tested for germination and initial plant growth. Three different plant densities were tested by in vitro culture (8, 10 and 12 plants per container). MS1/2 medium with 15g L-1 sucrose resulted in a higher percentage of germination and plant growth for the in vitro establishment of C. curralensis. The use of 12 plants per container is indicated for cost reduction in C. curralensis in vitro production.

ABSTRACT: Lychee is one of the most popular exotic fruits in Brazil, and has both in natura and industrial potential. The objective of the present study was to evaluate the influence of the number of leaflets on lychee herbaceous cuttings treated with the indolebutyric acid (1000mg L-1). The experimental design was completely randomized, with 4 replications and 10 cuttings per experimental plot. Treatments consisted of cuttings with zero (0), one (1), two (2), three (3), and four (4) leaflets. After 180 days, the rooting and survival percentages and the number and length of roots were evaluated. The data were subjected to polynomial regression analysis. The increase in the number of leaflets was advantageus for all studied variables, with an increase in the survival, rooting of cuttings, and number and length of roots. The herbaceous cuttings of lychee tree are viable, provided that at least four leaflets remain in the herbaceous cutting.

Published: April 2016

ABSTRACT: To occur seed germination distinct hydrolytic enzymes work together, enabling primary root protrusion. The objective of this study was to investigate changes in the activities of α-amylase, β-amylase, and glucose-6-phosphate dehydrogenase (G6PdH) during germination of Melanoxylon brauna Schott. seeds under thermal stress. To this end, seeds of this species were germinated under constant temperature (10, 25, 30 or 40°C) and samples were collected every 24h during a 96-h period, in which the activity of the enzymes were evaluated. At 25 and 30°C, optimal temperatures for the germination of the species, the activities of α-amylase, β-amylase, and G6PdH increased with seed imbibitions. At 10 and 40°C, enzyme activities decreased, impairing the germination process.

Published: April 2016

ABSTRACT: Crambe is a rapeseed with high oil content and can be used as a winter cover or as a source of raw material for the production of biodiesel, however espite the growing interest in the culture, research on the subject is still incipient, especially concerning the seed production and analysis technology. The purpose of this study is to evaluate the physiological quality of crambe seeds, 'FMS Brilhante' cultivar, by testing the pH of exudate. Five seed lots were submitted to the determination of water content and the tests of germination and vigor (first count, emergence and tetrazolium). In the conduction of pH exudate test, temperatures (25 and 30oC), and periods of seed imbibition in water (15, 30 and 45 minutes) were tested. The experiment was conducted in a completely randomized manner, with four replicates, and the mean values were compared by the Tukey test at 5% probability; Pearson correlation between the pH of the exudate and initial tests was also made. Testing the pH of exudate is promising for separating lots of crambe seeds and the following combinations of 25°C/30 minutes or 30°C/45 minutes can be used.
Rhomboid cutaneous flap for defect correction after resection of trichoblastoma on dogs' face
Authors: Araújo Priscilla Bartolomeu de , Bonelli Marília de Albuquerque , Campinho Daniela da Silva Pereira , Souza José Cláudio de Almeida , Coelho Maria Cristina de Oliveira Cardoso
Published: April 2016

ABSTRACT: Surgical excision of neoplasms usually requires a large incision with safety margin, resulting in large cutaneous defects. Skin flaps permit closure of extensive cutaneous defects that would not be closed directly. The rhomboid cutaneous flap can be used in places of the body where a rhomboid defect with internal angles of 60 and 120 degrees can be made. The aim of this paper is to report the her use for reconstruction of the defect created after resection of a tumor on dogs' face . Total removal of the tumor and a safety margin was performed, and then the surgical defect was reconstructed with a rhomboid cutaneous flap. The final result was satisfactory, with an esthetically and functional acceptable scar, a without deformities to the oral commissure or eye. The cutaneous flap was considered a viable alternative for reconstruction of large surgical defects, of relatively simple execution and good functional and cosmetic results.

Published: April 2016

ABSTRACT: Data from 629 meat type quails were used to study association between two different sets of traits: egg production and reproduction. Traits related to reproduction were: body weight at 42 days (W42), average egg weight (AEW), age at sexual maturity (ASM); and production traits: number of eggs produced from 42 until 182th day considering intervals of 35 days each period (P1, P2, P3 and P4). Canonical correlations were used to describe the association between these two sets of traits. The canonical coefficients indicated that egg production and reproductive traits were moderately related (0.3475). The first partial period of production (P1) and age at sexual maturity were the most relevant traits among the analyzed variables. Results show that selecting animals with lower age at sexual maturity might lead to an increase on number of eggs produced until 77 days, although it might also lead to a decrease on egg weight. Breeding programs aiming to improve quails production should consider selection strategies to decrease age at sexual maturity and then, as correlated response, increased egg production might be observed.

Published: April 2016

ABSTRACT: This study aimed to evaluate the growth of rubber tree clones ( Hevea brasiliensis (Willd.exA.Juss.) Müll. Arg.) in the Northwest region of Minas Gerais, Brazil. Randomized blocks, constituted of three treatments (rubber tree clones) and four repetitions were used, and evaluated as plots subdivided in time. Subplots represent the evaluations carried out at the ages 62, 77, 87, 99, 113 and 128 months after planting. It was evaluated survival, stem circumference and total plant height. Current annual increment and average annual increment of circumference and also the number of trees fit for rubber tapping were calculated. Results obtained indicate that clones GT 1, IAN 2880, IAC 15, RRIM 600, PB 235 and IAN 3156 have potential to establish under local edaphoclimatic conditions. Increase in plant height and stem circumference throughout the evaluation period makes it evident that the clones have different growing paces in the studied region. Clones GT 1, IAN 3087, IAN 3156 and PR 255 had larger stalk circumference at 128 months, and PR 255 was the only one fit for rubber tapping at the age of 128 months after planting.

ABSTRACT: The scientific and economic importance of soybean root rot justifies the study of this disease, especially the role of insects as dispersers in the spread of root pathogens. The objective was to identify and evaluate qualitatively and quantitatively the role of Cyclocephala modesta, Dyscinetus gagatesand Diloboderus abderus(Coleoptera: Melolonthidae) in the dispersion of root pathogens in cultivated fields. The fungi were identified to the species level with DNA extraction and sequencing of these organisms within Melolonthidae larvae. Larvae were dissected and separated into the parts: mouth parts, prothorax, cuticle and digestive tract (alimentary canal). The Internal Transcribed Spacer region of the rRNA was amplified and compared to sequences deposited in GenBank. This is the first record of dispersion Fusarium oxysporumby Cyclocephala modesta, Dyscinetus gagatesand Diloboderus abderus (Coleoptera: Melolonthidae) under soybean in Brazil.

ABSTRACT: The aim of this study was to evaluate the effects of Allopurinol in foals born from mares with placentitis. Twenty foals were assigned into two groups: Healthy foals (n=10), born from healthy mares and Placentitis foals (n=10), born from mares with placentitis. Five foals from each group were randomly assigned to a treatment or control group. Treatment groups received Allopurinol (40mg kg-1 orally six hours after birth). Blood samples were collected for estimation of hematological variables and serum concentration of calcium, chloride, creatinine, phosphorus, glucose, lactate and magnesium. Placentitis foals presented leukopenia and neutropenia when compared with Healthy foals, at birth. The white blood cell (WBC) count was lower in the Placentitis foals untreated at 12 hours. No adverse effects related to the use of Allopurinol were detected. Treated Placentitis foals showed higher serum calcium and glucose levels within 12 hours than untreated Placentitis foals. Administration of Allopurinol PO in foals born from mares with placentitis did not result in adverse effects and can help in stabilizing serum calcium and glucose levels.

ABSTRACT: There is a large number of studies evaluating methods to quantify biomass for the genus Pinus in different regions of Brazil. However, knowledge about this subject in the Northeast region of Brazil is still incipient. The objective of the present study was to assess the biomass and carbon stocks and select mathematical models to estimate these variables in Pinus caribaea var. hondurensis , which is established in homogenous stands in the Southwest region of the state of Bahia (Brazil). The biomass was quantified using the destructive method. Samples of needles, bole, bark, and branches were analyzed to determine their carbon contents. Ten models were tested, and the best of them were chosen based on the following statistical indicators: adjusted determination coefficient, estimate standard error, maximum likelihood logarithm, and graphical analysis of waste. Values for total biomass and carbon stocks were 69 and 42Mg ha-1, respectively. Curtis and Schumacher-Hall Log models showed to be the most indicated to estimate the total dry biomass and carbon of the species under the conditions studied.

ABSTRACT: The increasing consumption of single-head broccoli is due to several factors, among them there are food production in minimally processing form and the existence of hybrids that adapt to various climates, in addition to the simple harvesting of this typical architecture.This study aimed to identify the most relevant plant characters of broccoli, represented by growth characters, which are determinant in the production and canopy area. The study was conducted in an experimental area in Pato Branco city, PR. The 11 characters were evaluated for 365 plants, spaced with 0.8x0.5m, on a blank experiment. The characters of group 1 (height, number of leaves, stem height, stem diameter) were evaluated on the 21 and 58 day after transplanting (DAT), and the leaf area was evaluated on the 17 and 32 DAT. The characters of group 2 were quantity of fresh head mass and canopy area. At the initial stage of cultivation, on the 17 and 21 DAT, variations in the plants characters did not lead toany variation in production. The higher number of leaves and the larger stem diameter on the 58 DAT determined the greater mass of the broccoli heads.

ABSTRACT: The objective of this study was to evaluate the effect of different gliricidia planting densities on productive and qualitative parameters. The experiment was carried out at the Experimental Station Pedro Arle, Embrapa Tabuleiros Costeiros (Embrapa Coastal Tablelands), in Frei Paulo, Sergipe, Brazil. The effect of densities of 10,000; 20,000; 30,000 and 40,000 plants ha-1 was tested in biomass production (fresh and dry), dry matter content (DM), crude protein (CP), neutral detergent fiber (NDF), and acid-detergent fiber (ADF), in gliricidia leaves and tender stems. The experiment consisted of a randomized block design with four replications. Production of leaf and stem fresh biomass; production of leaf dry matter; percentage of fresh leaves in relation to the total fresh matter; and percentage of leaf dry matter of 13 cuttings were evaluated from September 2nd, 2009 to December 18th, 2013. There was increase in the production of total fresh matter, leaf fresh matter, and leaf dry matter (P<0.05) in planting densities greater than 20,000 plants ha-1. Year effect (P<0.05) was found only for total production of fresh matter, production of fresh leaves, percentage of leaf fresh matter, leaf dry matter content and crude protein.

Published: April 2016

ABSTRACT: Rhipicephalus ( Boophilus) species are monoxenous ticks with seasonal distribution in tropical and subtropical regions. For many years, Rhipicephalus micropluswas considered as a single species; however, further analysis split these ticks into two distinct species. Because R. microplusand R. australisshare similar attributes, it is hard to discriminate these two species and explain the changes in the classification of these parasites over the past decades. The reappearance of R. australisis an outcome of new research, which has afforded to better characterize these probably cryptic species. Evidence based on morphological features, the lack of conspecificity, microsatellite markers, mitochondrial 12S and 16S ribosomal DNA, and mitochondrial genome supports the re-classification of R. microplusas different species. Therefore, populations of R. microplusfrom Australia, Cambodia, Philippines, Indonesia, New Caledonia, Borneo, New Guinea, Tahiti and parts of Southeast Asia were recently reinstated as R. australis. Moreover, a better knowledge on the speciation between these two species could pave the way to important advances in tick control strategies.

ABSTRACT: In cattle, abdominal tumors leading to partial or total intestinal obstruction are rare. Here, it is described the clinico-pathological findings of two cows with intestinal obstruction by neoplasms. A crossbred cow presented apathy, weight loss, constipation, enophthalmos, ruminal and intestinal hypomotility, and abdominal distension in the right ventral quadrant. Pathological examination revealed bilateral ovarian teratoma. The other case was a cow that in the past 2 years had several episodes of squamous cell carcinoma in the third eyelid and vulva. During the 6 days prior to investigation, clinical signs of constipation and tenesmus were noted. Nodular and friable masses were located in the vulva, right third eyelid and cranially to the right kidney that were identified as poorly differentiated metastatic carcinoma of the adrenal cortex. To our knowledge, these are probably the first reports of ovarian teratoma and adrenal carcinoma causing clinical signs of intestinal obstruction in cattle.

Published: April 2016

Resumo: A partir da constatação da importância da indústria agroalimentar (IAA) brasileira como geradora de emprego, o presente trabalho analisou a variação no número de pessoas ocupadas nesta indústria no período de 1996 a 2012. Mediante a análise shift share (SSA) foram verificados quais efeitos são os responsáveis pelas mudanças no número de ocupados. Os efeitos utilizados no trabalho provêm das versões mais modernas e completas da SSA, de modo que foram analisados os efeitos nacional, estrutural, competitivo de mercado e competitivo de especialização, bem como a decomposição homotética e residual de cada um desses. O trabalho levou em consideração as regiões Sul e Sudeste, com exceção do Espírito Santo. Ao mesmo tempo, a base de dados também foi segmentada de acordo com os setores de atividades que formam a IAA. Os resultados encontrados indicam que o número de ocupados da IAA variou devido ao efeito nacional, ou seja, seguiu a corrente da indústria nacional, sem apresentar qualquer diferencial na sua estrutura ou na sua estratégia competitiva que pudesse ser identificada nesta análise.

Objetivou-se com este estudo estimar parâmetros genéticos para produções parciais e acumuladas de ovos em uma linha fêmea de frangos de corte comercial. Foram considerados 10 períodos mensais entre 25 e 64 semanas, três períodos parciais de 25 a 32, 33 a 48 e 49 a 64 semanas, e três períodos acumulados de 25 até 30, 40 e 50 semanas de idade. Os componentes de covariância e parâmetros genéticos foram obtidos pelo método da máxima verossimilhança restrita, sob o modelo animal considerando o efeito fixo de incubação e os efeitos aleatórios genético aditivo e residual. As estimativas de herdabilidade variaram de 0,12 a 0,41. Evidenciou-se que os períodos anteriores e posteriores ao maior nível de produção apresentam maior variabilidade genética. As correlações genéticas entre os períodos de produção de ovos estudados variaram de -0,12 a 0,98. De modo geral, o padrão de variação foi semelhante entre as estratégias avaliadas, e todas foram geneticamente associadas com a produção total. Os resultados deste estudo mostraram que a melhoria da produção total é viável por meio de seleção de registros parciais. No entanto, caso se considere a eficiência relativa de seleção, o segundo mês e os períodos a partir da quadragésima semana de produção seriam os mais indicados.
