The Phenomenon of Climate Change in Organization and HR- Related Literature: A Conceptual Brief Analysis
Authors: Mousa Mohamed
Published: April 2018

Climate change has become one of the main challenges facing humanity. Over the past decade, this phenomenon, which may have been caused by natural variability and/or human activity, has attracted many scholars from different scientific disciplines to warn of its potential consequences. The author of this paper has decided to address the existence of this important phenomenon in organizational literature. However, upon exploring different academic databases, the rarity of research focusing on climate change and its relationship and/or effect on HR or organizational aspects became obvious. Accordingly, the author recommends other HR and organizational scholars devote considerable space to this phenomenon in their field.

Authors: Zhen-fei Wang , Li Liu , Lin Liang , Qin Hao
Published: April 2018

Objective

The aim of this study was to investigate the effect of Radix Glehniae on the migration and invasion abilities of lung cancer cells.

Methods

Normal bronchial cell line 16HBE and lung cancer cell line SK-MES-1 were treated with Radix Glehniae extract. Proliferation, migration, and invasion abilities were determined by Cell Counting Kit (CCK)-8, Transwell, and Matrigel assays, respectively. The expression and secretion levels of tissue inhibitor of metalloproteinases 2 were detected by quantitative PCR and enzyme-linked immunosorbent assay, respectively.

Results

Radix Glehniae extract inhibited the migration and invasion abilities of SK-MES-1 cells and enhanced TIMP2 expression and secretion by SK-MES-1 cells, without causing toxicity to 16HBE cells.

Conclusion

Radix Glehniae is useful in lung cancer treatment.
Abnormal platelet count correlates with poor survival in hepatocellular carcinoma
Authors: Gu Lei , Wen Wen , Wu ZhiXian , Bai Kai , Liu Wei , Lai GuoXiang , Li DongLiang
Published: April 2018

Background

Normal platelet (PLT) plays a vital role in thrombosis, the inflammatory response, and liver regeneration. The effect of abnormal PLT counts has been seldom explored in hepatocellular carcinoma (HCC); hence, this investigation was conducted to evaluate the prognostic importance of preoperative abnormal PLT count in HCC patients after liver resection retrospectively.

Methodology

The PLT counts were determined using Sysmex XT-1800i automated hematology analyzer and its matching reagents. Patients were divided into two groups: a normal PLT group and an abnormal PLT group. Chi-square test, Kaplan–Meier method, and Cox univariable and multivariable regressions were utilized to analyze the data.

Results

A total of 391 HCC patients who underwent liver resection were included in this study. The overall survival (OS) rates were 59% and 31%, and the median survival time was 69 months and 31 months in the normal and abnormal PLT groups, respectively. The PLT level was associated with OS in univariate and multivariate analyses (hazard ratio [HR], 1.991 [95% confidence interval {CI}, 1.412–2.808] and HR, 2.217 [95% CI, 1.556–3.159], respectively).

Conclusions

Patients with normal PLT had a better outcome in terms of OS. The results suggested that abnormal PLT count is an independent prognostic factor for HCC patients after liver resection.

Published: April 2018

The study aimed to investigate the correlation between concentration of inhaled arsenic trioxide and dynamic changes in hematotoxicity in rats. Wistar rats were randomly divided into four study groups that were treated with saline (control) or arsenic trioxide at a low (0.1 mg/mL), medium (1 mg/mL), or high (10 mg/mL) dose by intratracheal instillation. Blood samples were collected for analysis at 6, 12, 24, 48, and 72 h after exposure. Compared with the control group, intratracheal instillation of arsenic trioxide affected hematopoietic differentiation in rats, leading to blood cell changes that were related to observation time and concentration.

Authors: Li Zhi-Jian , Sui Xing-Ling , Yang Xue-Bo , Sun Wen
Published: April 2018

To reveal the biology of AML, we compared gene-expression profiles between normal hematopoietic cells from 38 healthy donors and leukemic blasts (LBs) from 26 AML patients. We defined the comparison of LB and unselected BM as experiment 1, LB and CD34+ isolated from BM as experiment 2, LB and unselected PB as experiment 3, and LB and CD34+ isolated from PB as experiment 4. Then, protein–protein interaction network of DEGs was constructed to identify critical genes. Regulatory impact factors were used to identify critical transcription factors from the differential co-expression network constructed via reanalyzing the microarray profile from the perspective of differential co-expression. Gene ontology enrichment was performed to extract biological meaning. The comparison among the number of DEGs obtained in four experiments showed that cells did not tend to differentiation and CD34+ was more similar to cancer stem cells. Based on the results of protein–protein interaction network,CREBBP,F2RL1,MCM2, andTP53were respectively the key genes in experiments 1, 2, 3, and 4. From gene ontology analysis, we found that immune response was the most common one in four stages. Our results might provide a platform for determining the pathology and therapy of AML.
Priority and Unity in Frege and Wittgenstein
Authors: Spinney Oliver Thomas
Published: April 2018

In the following article I intend to examine the problem of the unity of the proposition in Russell, Frege, and Wittgenstein. My chief aim will be to draw attention to the distinction between Russell’s conception of propositional constituents, on the one hand, with Frege and Wittgenstein’s on the other. My focus will be on Russell’s view of terms as independent, propositions being built up out of these building blocks, compared with Frege and Wittgenstein’s ‘top down’ approach. Furthermore, I will argue that, contra certain other commentators, Frege’s metaphor of saturation and unsaturation does not serve as a solution to the problem of unity, and that the extension of this metaphorical language to Wittgenstein is, therefore, inappropriate.
Heart Transplantation for Adult Congenital Heart Disease: Overview and Special Considerations
Authors: Gupta Dipankar , Reid Jana , Moguillansky Diego , Shih Renata , Bleiweis Mark S. , Fricker Frederick J. , Pietra Biagio A.
Published: April 2018

With improvements in their surgical and medical management, the number of patients with congenital heart disease (CHD) reaching adulthood has increased over the last decade. As the population of adult CHD patients continues to rise, an increasing number of these patients will require evaluation for heart transplantation. It is important to recognize advanced heart failure and other associated complications early in this cohort of complex patients for early referral to an adult CHD specialist. As these patients present with unique challenges because of their multiple comorbidities and complex anatomy, there needs to be a careful selection process for transplantation to optimize the utilization of donor organs.
Attention Selectively Gates Afferent Signal Transmission to Area V4

Published: April 2018

Selective attention allows focusing on only part of the incoming sensory information. Neurons in the extrastriate visual cortex reflect such selective processing when different stimuli are simultaneously present in their large receptive fields. Their spiking response then resembles the response to the attended stimulus when presented in isolation. Unclear is where in the neuronal pathway attention intervenes to achieve such selective signal routing and processing. To investigate this question, we tagged two equivalent visual stimuli by independent broadband luminance noise and used the spectral coherence of these behaviorally irrelevant signals with the field potential of a local neuronal population in male macaque monkeys' area V4 as a measure for their respective causal influences. This new experimental paradigm revealed that signal transmission was considerably weaker for the not-attended stimulus. Furthermore, our results show that attention does not need to modulate responses in the input populations sending signals to V4 to selectively represent a stimulus, nor do they suggest a change of the V4 neurons' output gain depending on their feature similarity with the stimuli. Our results rather imply that selective attention uses a gating mechanism comprising the synaptic “inputs” that transmit signals from upstream areas into the V4 neurons. A minimal model implementing attention-dependent routing by gamma-band synchrony replicated the attentional gating effect and the signals' spectral transfer characteristics. It supports the proposal that selective interareal gamma-band synchrony subserves signal routing and explains our experimental finding that attention selectively gates signals already at the level of afferent synaptic input.

SIGNIFICANCE STATEMENTDepending on the behavioral context, the brain needs to channel the flow of information through its networks of massively interconnected neurons. We designed an experiment that allows to causally assess routing of information originating from an attended object. We found that attention “gates” signals at the interplay between afferent fibers and the local neurons. A minimal model demonstrated that coherent gamma-rhythmic activity (∼60 Hz) between local neurons and their afferent-providing input neurons can realize the gating. Importantly, the attended signals did not need to be amplified already in an earlier processing stage, nor did they get amplified by a simple output response modulation. The method provides a useful tool to study mechanisms of dynamic network configuration underlying cognitive processes.

Microglia are the resident immune cells of the CNS, and their response to infection, injury and disease is well documented. More recently, microglia have been shown to play a role in normal CNS development, with the fractalkine-Cx3cr1 signaling pathway of particular importance. This work describes the interaction between the light-sensitive photoreceptors and microglia during eye opening, a time of postnatal photoreceptor maturation. Genetic removal of Cx3cr1 (Cx3cr1GFP/GFP) led to an early retinal dysfunction soon after eye opening [postnatal day 17 (P17)] and cone photoreceptor loss (P30 onward) in mice of either sex. This dysfunction occurred at a time when fractalkine expression was predominantly outer retinal, when there was an increased microglial presence near the photoreceptor layer and increased microglial–cone photoreceptor contacts. Photoreceptor maturation and outer segment elongation was coincident with increased opsin photopigment expression in wild-type retina, while this was aberrant in theCx3cr1GFP/GFPretina and outer segment length was reduced. A beadchip array highlighted Cx3cr1 regulation of genes involved in the photoreceptor cilium, a key structure that is important for outer segment elongation. This was confirmed with quantitative PCR with specific cilium-related genes,RpgrandRpgrip1, downregulated at eye opening (P14). While the overall cilium structure was unaffected, expression of Rpgr, Rpgrip1, and centrin were restricted to more proximal regions of the transitional zone. This study highlighted a novel role for microglia in postnatal neuronal development within the retina, with loss of fractalkine–Cx3cr1 signaling leading to an altered distribution of cilium proteins, failure of outer segment elongation and ultimately cone photoreceptor loss.

SIGNIFICANCE STATEMENTMicroglia are involved in CNS development and disease. This work highlights the role of microglia in postnatal development of the light-detecting photoreceptor neurons within the mouse retina. Loss of the microglial Cx3cr1 signaling pathway resulted in specific alterations in the cilium, a key structure in photoreceptor outer segment elongation. The distribution of key components of the cilium transitional zone, Rpgr, Rpgrip1, and centrin, were altered in retinae lacking Cx3cr1 with reduced outer segment length and cone photoreceptor death observed at later postnatal ages. This work identifies a novel role for microglia in the postnatal maturation of retinal photoreceptors.
The impact of fossil fuel burning related to scientific activities in the McMurdo Dry Valleys, Antarctica: Revisited
Authors: Lyons W. Berry , Saelens Elsa , Welch Kathleen A.
Published: April 2018

Fossil fuel use associated with scientific activities in the Taylor Valley, Antarctic has been examined to determine the fluxes of particulate organic and elemental carbon and nitrogen as well as NOx for the 2015–2016 austral summer field season. These carbon and nitrogen fluxes are compared to our previously published calculations for the 1997–1998 austral summer. In addition, we compile fossil fuel usage and resulting C and N fluxes from the major field camp in Taylor Valley, Lake Hoare Camp (LHC) from the late 1990’s through 2017. In general, the annual fluxes do vary from year to year, but there is no significant trend, at least during the primary summer field season. There is indication that increasing the length of scientific operations does increase the C and N inputs via fossil fuel burning. This works supports our original results demonstrating that over long periods of time the anthropogenic flux of N from local fossil fuel burning could become quantitatively important in the region. Although the particulate C fluxes remain very low, the recent finding of black carbon in the Taylor Valley landscape indicates more on-going monitoring of the source of this material is merited.

Authors: van Baar Annieke C G , Prodan Andrei , Wahlgren Camilla D , Poulsen Steen S , Knop Filip K , Groen Albert K , Bergman Jacques J , Nieuwdorp Max , Levin Evgeni
Published: April 2018

Background

Enteroendocrine cells are essential for the regulation of glucose metabolism, but it is unknown whether they are associated with clinical features of metabolic syndrome (MetS) and fasting plasma metabolites.

Objective

We aimed to identify fasting plasma metabolites that associate with duodenal L cell, K cell and delta cell densities in subjects with MetS with ranging levels of insulin resistance.

Research design and methods

In this cross-sectional study, we evaluated L, K and delta cell density in duodenal biopsies from treatment-naïve males with MetS using machine-learning methodology.

Results

We identified specific clinical biomarkers and plasma metabolites associated with L cell and delta cell density. L cell density was associated with increased plasma metabolite levels including symmetrical dimethylarginine, 3-aminoisobutyric acid, kynurenine and glycine. In turn, these L cell-linked fasting plasma metabolites correlated with clinical features of MetS.

Conclusions

Our results indicate a link between duodenal L cells, plasma metabolites and clinical characteristics of MetS. We conclude that duodenal L cells associate with plasma metabolites that have been implicated in human glucose metabolism homeostasis. Disentangling the causal relation between L cells and these metabolites might help to improve the (small intestinal-driven) pathophysiology behind insulin resistance in human obesity.
Stonewall and Brickwall: Two Partially Redundant Determinants Required for the Maintenance of Female Germline inDrosophila
Authors: Shukla Vallari , Dhiman Neena , Nayak Prajna , Dahanukar Neelesh , Deshpande Girish , Ratnaparkhi Girish S
Published: April 2018

Proper specification of germline stem cells (GSCs) in Drosophila ovaries depends on niche derived non-autonomous signaling and cell autonomous components of transcriptional machinery. Stonewall (Stwl), a MADF-BESS family protein, is one of the cell intrinsic transcriptional regulators involved in the establishment and/or maintenance of GSC fate in Drosophila ovaries. Here we report identification and functional characterization of another member of the same protein family, CG3838/ Brickwall (Brwl) with analogous functions. Loss of function alleles of brwl exhibit age dependent progressive degeneration of the developing ovarioles and loss of GSCs. Supporting the conclusion that the structural deterioration of mutant egg chambers is a result of apoptotic cell death, activated caspase levels are considerably elevated in brwl- ovaries. Moreover, as in the case of stwl mutants, on several instances, loss of brwl activity results in fusion of egg chambers and misspecification of the oocyte. Importantly, brwl phenotypes can be partially rescued by germline specific over-expression of stwl arguing for overlapping yet distinct functional capabilities of the two proteins. Taken together with our phylogenetic analysis, these data suggest that brwl and stwl likely share a common MADF-BESS ancestor and they are expressed in overlapping spatiotemporal domains to ensure robust development of the female germline.
Efficient Expression of Genes in theDrosophilaGermline Using a UAS Promoter Free of Interference by Hsp70 piRNAs

Controlling the expression of genes using a binary system involving the yeast GAL4 transcription factor has been a mainstay of Drosophila developmental genetics for nearly 30 years. However, most existing GAL4 expression constructs only function effectively in somatic cells, but not in germ cells during oogenesis, for unknown reasons. A special upstream activation sequence (UAS) promoter, UASp was created that does express during oogenesis, but the need to use different constructs for somatic and female germline cells has remained a significant technical limitation. Here, we show that the expression problem of UASt and many other Drosophila molecular tools in germline cells is caused by their core Hsp70 promoter sequences, which are targeted in female germ cells by Hsp70-directed Piwi-interacting RNAs (piRNAs) generated from endogenous Hsp70 gene sequences. In a genetic background lacking genomic Hsp70 genes and associated piRNAs, UASt-based constructs function effectively during oogenesis. By reducing Hsp70 sequences targeted by piRNAs, we created UASz, which functions better than UASp in the germline and like UASt in somatic cells.
Erythropoietin and treatment of cancer-associated malignant anemia

Published: April 2018

Cancer anemia, which is known as the malignant anemia associated with cancer, is one of the clinical symptoms of cancer and occurs in about half of cancer patients. Malignant tumor anemia is a common complication in various malignant tumors. In this anemia, the destruction of red blood cells leads to a decrease in access of tissues to oxygen leading to a reduced sensitivity of tumors to treatments such as radiotherapy and chemotherapy, and thus reduced quality of life in patients, reduced survival time and impact on the cancer prognosis. So, that the mortality rate in patients with anemia is two times higher than the patients without anemia during three years after diagnosis of cancer. Despite the fact that some studies have found that erythropoietin may improve symptoms of cancer-related anemia, this issue is still controversial in scientific literature and sessions.

Published: April 2018

An effective faculty mentoring program (FMP) is 1 approach that academic departments can use to promote professional fulfillment, faculty retention, and mitigate the risks of faculty burnout. Mentoring has both direct benefits for junior faculty mentees as they navigate the academic promotion process with their mentors, in addition to broader departmental and institutional benefits, with regard to recruitment, retention, and academic productivity. We describe a successful FMP model that has been adapted for use in 6 other pediatrics departments, summarizing the key personnel, mentoring process, and program evaluation methods. Important lessons learned and a generalizable mentoring “model” are provided. Program evaluation indicates a positive effect for the FMP on enhanced faculty self-efficacy, job satisfaction, and career development. The importance of communication, oversight, feedback, accountability, and valuing all faculty members is emphasized. Strategies to promote faculty engagement and the critical role of departmental leadership in prioritizing mentorship are discussed. The success of academic medical departments is inextricably linked to its commitment to the career development of individual faculty members at all levels and in all academic pathways. With our findings, we support the positive impact of a formal FMP in promoting enhanced self-efficacy and career satisfaction, which directly benefits the department and institution through enhanced productivity, retention, successful promotion, and overall professional fulfillment.

La Nueva Organización Anticomunista (NOA). Historia represiva de un escuadrón de la muerte paraestatal
Authors: López de la Torre Carlos Fernando
Published: April 2018

El artículo examina la historia de la Nueva Organización Anticomunista (NOA), un escuadrón de la muerte paraestatal que existió en Guatemala entre 1967 y 1968, teniendo como objetivo central el análisis de la violencia política y, específicamente, del papel que ejerció en la represión de las disidencias políticas de la época. Para cumplir con tal propósito, se plantea, en primer término, un abordaje teórico que busca definir las características de los escuadrones como actores represivos. A continuación, se presenta el contexto y desarrollo del complejo contrainsurgente represivo que dio origen a la NOA durante la presidencia de Julio César Méndez Montenegro (1966-1970). Posteriormente y con base en fuentes de época y bibliografía especializada, se traza el devenir de la organización, atendiendo sus objetivos, composición social, mecanismos de actuación y repercusiones de sus crímenes. La investigación muestra cómo la violencia de la NOA fue capital en la propagación del terror a finales de la década de 1960 y en el desarrollo de un consenso conservador que posibilitó el retorno de los militares a la presidencia nacional en 1970; razones que resaltan la importancia de atender el conflicto armado interno partiendo del estudio de los llamados perpetradores.

No escuro, os arqueólogos gostam de ficar em silêncio: o argumento do silêncio e a historicidade da anistia de Pilatos a Barrabás
Authors: Torres Milton L.
Published: April 2018

Invoca-se, com frequência, o argumento do silêncio para colocar em dúvida a existência histórica de Jesus Barrabás, o personagem enigmático a quem, de acordo com os evangelhos, a turba preferiu libertar em detrimento de Jesus Cristo. De fato, o personagem não é mencionado senão nos evangelhos. Tampouco se percebem referências históricas inequívocas ao costume romano ou judaico de se libertar um prisioneiro durante a páscoa, o assim-chamado privilégio pascoal. Este artigo pretende, portanto, analisar a força argumentativa desse duplo argumento do silêncio e apresentar um breve resumo da evidência geralmente apresentada por historiadores e arqueólogos contra e a favor do privilégio pascoal. Finalmente, o artigo propõe uma breve reflexão sobre o valor geral de um argumento do silêncio.

Abstract This study aimed to carry out an ethnobotanical survey of medicinal plants used by inhabitants of the Rodeadouro Island, Jatoba Island and Massangano Island, located in The Submedium São Francisco River Valley. Also phytochemicals and preliminary pharmacological tests were performed to species most cited by the community. Ethnobotanical data were collected through observation visits and semi-structured interviews with 12 key informants. We calculated the relative importance (RI), the percentage of agreement related to the main uses (cAMU) and use value (UV). The aerial parts of Rhaphiodon echinus (Ness & Mart.) Schauer were used to obtain the lyophilizate (LYO-Re), crude ethanol extract (CEE-Re) and their hexanic (HEX-Re), chloroform (CLO-Re) and ethyl acetate (EA-Re) fractions. The microdilution technique was used for determining Minimum inhibitory concentration (MIC) for selected microorganisms. Already the spasmolytic effect was evaluated in isolated uterus fragments of Wistar rats, pre contracted with KCl 60 mM. We found 34 species cited, belonging to 22 families. The most plants were grown by locals. There were 51 different diseases, but the main indication was infectious and parasitic diseases. The species R. echinus was the most reported and it was indicated for urinary tract infection and dysmenorrhea. The screening revealed a higher prevalence of flavonoids, tannins, lignans and saponins in LYO-Re and AE-Re. Already terpene compounds were more present in HEX-Re and CLO-Re. The RE-Re fraction stood out with strong effect against E. coli and S. aureus while CEE-Re has moderate effect against gram-negative bacteria. The evaluation of the spasmolytic activity showed that LYO-Re, CEE-Re and HEX-Re fractions have similar activity, with partial effect and concentration-dependent response. This work brought about knowledge and use of medicinal plants by the riparian of the São Francisco River. It also revealed the importance of other methodologies for scientific evidence for the popular use of R. echinus.

Published: April 2018

Abstract Analysis of abundance and population structure of Plesionika narval was performed on data concerning 5,255 specimens obtained from 62 fishing sets carried out off the Madeira archipelago (Northeastern Atlantic) between 2004 and 2008 in a depth range from 101 to 350 m. Abundance ranged from 0.01 to 19.74 specimens-per-trap and significant differences were found between seasons, probably as a result of an increment of population in the spring during the recruitment season. The analysis of size distribution revealed that the carapace length (CL) ranged from 2.45 to 28.61 mm and that mean female size consistently exceeded that of males. Differences in mean CL were statistically significant between depth strata and seasons. Of the specimens sampled, 57.00% were males, 41.88% females and 1.42% undetermined. Sex ratio also differed significantly between seasons according to depth strata, consolidating the hypothesis of the existence of seasonal migrations related with the reproductive cycle of this species. Ovigerous females showed larger sizes and occurred all year around and remain in shallow waters in winter, summer and autumn and move to deeper waters in spring. The highest frequency of ovigerous females was recorded in summer, between 151 and 200 m deep supporting the hypothesis that spawning of this species occurs in shallow waters, especially in late summer.

Abstract Renal oncocytoma is an infrequently reported renal neoplasm, often asymptomatic, which usually behaves as a benign entity and is identified accidentally on radiological imaging. Transplant patients under long-term immunosuppressive drugs have a high prevalence of cancers, such as skin cancers, lymphoproliferative disorders, and renal carcinomas. We present a case report of an asymptomatic renal oncocytoma in a kidney transplant recipient presenting persistent hematuria. The features of computed tomography and contrast-enhanced ultrasound (CEUS) are presented. This was the first time we used CEUS in a transplant kidney recipient presenting a renal mass, allowing the real-time visualization of contrast-enhancement patterns during all vascular phases for the differential diagnosis of renal tumors. Although the pattern of intense vascularization could mislead to an early judgment as a malignant lesion, it could help to exclude other renal lesions without inducing nephrotoxicity.

ABSTRACT Introduction: Posterior reversible leukoencephalopathy syndrome (PRES) was first described by Hinchey in 1996. The syndrome is characterized by altered level of consciousness, headache, visual changes, and seizures associated with a vasogenic edema of the white matter that occurs predominantly in the occipital and parietal lobes. Imaging tests such as computed tomography (CT) and especially magnetic resonance imaging (MRI) support the diagnosis. Case Report: We report a case of a 48-year-old female patient who underwent a deceased donor kidney transplant and received tacrolimus as a part of the immunosuppressive regimen. Five weeks after transplantation she was admitted to the emergency due to sudden onset of confusion, disorientation, visual disturbances, and major headache. PRES was suspected and the diagnosis confirmed by brain MRI. Tacrolimus was withdrawn and rapid improvement of the neurological signs occurred leading to the conclusion that this drug triggered the syndrome. Conclusion: PRES is an unusual complication after organ transplantation and should be considered in the appropriate clinical setting. Physicians must be aware of this condition in order to provide early detection and appropriate treatment since delay in removing the cause may lead to permanent sequelae.

ABSTRACT We analyzed the spatial distribution pattern of Pentaclethra macroloba to assist in the development of management plans and conservation of this species in estuarine floodplain forests. The study was conducted in an area of floodplain forest of 55.94 ha, in Mazagão, Amapá, Brazil. A census was performed and all individuals of ≥ 30 cm circumference at breast height (CBH), living and dead, were georeferenced. Ripley’s K function was used to analyze the spatial distribution of the population, including mortality and diameter classes. The relationships between distance to the edge of inundation and density and basal area of the population were analyzed using linear regression. We recorded 993 live individuals and 22 dead. The distribution of the population was found to vary with the topographic gradient associated with the distance to the edge of the inundation. Diameter classes 1 (≤ 13.2 cm) and 2 (≤ 18.6 cm) were spatially aggregated close to the water and randomly distributed far from the water. Classes 3 (≤ 24.0 cm) and 4 (≤ 29.5 cm) were aggregated at all distances, and classes 5 (≤ 34.9 cm), 6 (≤ 40.3 cm), 7 (≤ 45.7 cm) and 8 (≤ 51.2 cm), were randomly distributed at all distances. Mortality was randomly distributed. The population density was 18 trees h-1 with a basal area of 49 m2 h-1, and both density (r2=0.51; p=0.0195) and basal area (r2=0.67; p=0.0039) increased with the distance from the edge of the inundation. We conclude that the spatial distribution and successful establishment of this species in floodplain forest are related to the dynamics of flooding and the resultant impacts on dispersal processes.

ABSTRACT This study aimed to create a system to assess the potential tree fall risk (SARPQA) and to assess all the trees in the Museum Paraense Emílio Goeldi Zoo (PZB/MPEG) and in the Rodrigues Alves Park/Botanical Garden of Amazônia (BRA/JBA). We analyzed aspects, such as diameter at breast height (DBH), tree total heigh, surface biomass, apparent phytosanitary, stem inclination, canopy balance and presence of lianas. We assessed 1074 trees (DBH e” 20 cm) distributed in 229 species and 40 families. The average stem height, the total height and diameter at breast height were 10.9 m, 18.7 m and 41.9 cm respectively. The SARPQA showed that 23 trees had very high risk of fall, 142 had high risk, 750 individuals had medium and low risk and 159 had very low risk. Both parks have hundreds of large trees, which associated with the amount of people using these spaces, can increase the risk of accidents by tree fall. Trees with high risk of fall need immediate attention because they present risks to human life and/or property. The system proposed in this study proved to be practical and can be an effective tool for decision makers in the management of urban parks.

ABSTRACT The aim of this study was to evaluate DNA integrity and to identify ultrastructural changes in the primary root of Peltophorum dubium seeds subjected to drying, since these changes may reflect the germination capacity. Seeds were germinated and were dehydrated when reached 1 mm in length of the primary root, until reaching different moisture contents, being then rehydrated and evaluated in relation to survival. After this procedure, different points of interest (control, 20% and 10% moisture content) were selected to evaluate DNA and cell ultrastructure integrity in order to detect possible cellular changes in primary roots after dehydration. When dried down to 32% moisture, there was no influence on the growth resumption of the germinated seeds, but when they were dehydrated to 20% moisture, the survival was reduced to 67%, reaching nullity in the survival with drying to 8% moisture. By the evaluation of ultrastructural changes in root cells, it was observed that drying to approximately 20% moisture content marked the onset of damages by desiccation, both physiologically and ultrastructurally. Drying to levels close to 10% moisture content was not only responsible for total disorganization and rupture of membranes, but also promoted intracellular collapse. Loss of genomic DNA integrity was observed during drying.

Published: April 2018

ABSTRACT In this study, composites with three types of thermoplastic matrix and cellulosic material in a proportion of 40% were produced. The three thermoplastic matrices were high density polyethylene (HDPE), polypropylene (PP) and low density polyethylene (LDPE), and the cellulosic materials were pure wood flour (Pinus taeda L) or a mixture of wood flour and coconut shell flour (Cocus nucifera L) in equal ratios. The objective was to evaluate the influence of addition of coconut shell on the physico-mechanical properties (density, strength and rigidity) and the distribution of the cellulosic material in the thermoplastic matrix of the manufactured composites. It was found that the composites had a satisfactory distribution of wood flour in thermoplastic matrices, but the addition of coconut shell promoted bubble formation in the resulting pieces and, thus, interfered with the material properties. The use of a coupling agent promoted interfacial adhesion (cellulose - thermoplastic matrix), which was better in high density polyethylene composites, followed by polypropylene and low density polyethylene. In general, the coconut shell addition caused a decrease of all properties compared to composites made with Loblolly Pine. In addition, the interactions between thermoplastic type and cellulosic matrix type have been statistically confirmed, which caused variations in the studied properties

ABSTRACT Oil palm is a woody monocot of economic importance due to high oil production from its fruits. Currently, the conventional method most used to propagate oil palm is seed germination, but success is limited by long time requirements and low germination percentage. An alternative for large-scale propagation of oil palm is the biotechnological technique of somatic embryogenesis. The rooting of plants germinated from somatic embryos is a difficult step, yet it is of great importance for later acclimatization and success in propagation. The aim of this study was to evaluate the effect of the auxins indole acetic acid (IAA) and indole butyric acid (IBA) on the rooting of somatic embryos of Tenera hybrid oil palm. Plants obtained by somatic embryogenesis were inoculated in modified MS medium with 10% sucrose and 0.6% agar and supplemented with IAA or IBA at concentrations of 5 µM, 10 µM, and 15 µM, and the absence of growth regulators. After 120 days, the presence of roots, root type, length of the longest root, number of roots, number of leaves, and shoot length were analyzed. Growth regulators were favorable to rooting; plants cultivated with IBA growth regulator at 15 µM showed higher rooting percentage (87%) and better results for the parameters of number of roots (1.33) and shoot length (9.83).
