Ambulatory Care Coordination Issues With Dual Use Veteran Organ Transplant Recipients
Authors: Thrall Stephanie A. , Egede Leonard E. , Taber David J.
Published: March 2017

The previous literature indicates that patients receiving ongoing care in both Veterans Affairs (VA) and non-VA setting (dual care) may have reduced health outcomes. The objective of this study was to assess the impact of dual care provided to a veteran solid organ transplant population. This was a retrospective cohort study of stable solid organ transplant recipients receiving care at both a Veterans Affairs Medical Center and transplant center. Forty-six veteran organ transplant recipients met inclusion criteria. At baseline, mean age at transplant was 57 ± 10 years; 93% were male, 61% received kidney transplants. Thirty-nine percent of patients did not receive immunosuppressant concentrations at the recommended intervals. The incidence of veterans that had at least 2 providers caring for the same comorbidity was 63% for hypertension, 58% for diabetes, and 27% for dyslipidemia. Approximately one-third of veterans had documentation of care provided by the other institutions (30%-37%), and 93% of patients had medication regimen discrepancies between health-care systems, with 52% of patients having at least 1 medication discrepancy involving an immunosuppressant. Most veteran solid organ transplant recipients receive care across multiple health-care systems, with significant care coordination issues leading to gaps and duplications in their management. Improved communication between health systems is imperative to optimize outcomes in dual use veterans such as organ transplant recipients.

Published: March 2017

Increased oxidative stress plays an important role in heavy ion radiation–induced cell death. The mechanism involved in the generation of elevated reactive oxygen species (ROS) is not fully illustrated. Here we show that NADPH oxidase activation is closely related to heavy ion radiation–induced cell death via excessive ROS generation. Cell death and cellular ROS can be greatly reduced in irradiated cancer cells with the preincubation of diphenyleneiodium, an inhibitor of NADPH oxidase. Most of the NADPH oxidase (NOX) family proteins (NOX1, NOX2, NOX3, NOX4, and NOX5) showed increased expression after heavy ion irradiation. Meanwhile, the cytoplasmic subunit p47phox was translocated to the cell membrane and localized with NOX2 to form reactive NADPH oxidase. Our data suggest for the first time that ROS generation, as mediated by NADPH oxidase activation, could be an important contributor to heavy ion irradiation–induced cell death.
Time’s Calling: Time, Timing, and Transformation in Futures Work
Authors: Bussey Marcus
Published: March 2017

Futurists work with time, yet we rarely consider the full implications of what this means. It could equally be said that futurists work within time, navigating the cultures and ecologies of time that shape the worlds they seek to enable. The most interesting result of this way of looking at what futurists do, with and within time, is that it opens up a space for human action that is creative and reflexive. Futurists work with time not because their work concerns the future but because they are interested in change. Change is the work of heads, hands, and hearts over time. It is the result of both accident and intention and dominates our experience of Modernity. The futurist enters a change-context to help individuals, organizations, and communities enhance their adaptive potential. This paper works with thinking about time from a futures perspective. My goal is to drill down into the temporal inventiveness of futures work by dwelling on the linguistic and conceptual aspects of temporal discourse. What really interests me in this is how futurists can leverage a variety of temporal concepts to better achieve their goal of making elements of time, timing, and transformation explicit to their clients and students.

Background

Autologous stem cell transplantation (ASCT) for progressive multiple sclerosis (MS) may reset the immune repertoire.

Objective

The objective of this paper is to analyse lymphocyte recovery in patients with progressive MS treated with ASCT.

Methods

Patients with progressive MS not responding to conventional treatment underwent ASCT following conditioning with high-dose cyclophosphamide and antithymocyte globulin. Lymphocyte subset analysis was performed before ASCT and for two years following ASCT. Neurological function was assessed by the EDSS before ASCT and for three years post-ASCT.

Results

CD4+ T-cells fell significantly post-transplant and did not return to baseline levels. Recent thymic emigrants and naïve T-cells fell sharply post-transplant but returned to baseline by nine months and twelve months, respectively. T-regulatory cells declined post-transplant and did not return to baseline levels. Th1 and Th2 cells did not change significantly while Th17 cells fell post-transplant but recovered to baseline by six months. Neurological function remained stable in the majority of patients. Progression-free survival was 69% at three years.

Conclusion

This study demonstrates major changes in the composition of lymphocyte subsets following ASCT for progressive MS. In particular, ablation and subsequent recovery of thymic output is consistent with the concept that ASCT can reset the immune repertoire in MS patients.
The Role of Community Health Centers in Reducing Racial Disparities in Spatial Access to Primary Care
Authors: Seymour Jane W. , Polsky Daniel E. , Brown Elizabeth J. , Barbu Corentin M. , Grande David
Published: March 2017

Introduction: Racial minorities are more likely to live in primary care shortage areas. We sought to understand community health centers’ (CHCs) role in reducing disparities. Methods: We surveyed all primary care practices in an urban area, identified low access areas, and examined how CHCs influence spatial accessibility. Results: Census tracts with higher rates of public insurance (≥40% vs <10%, odds ratio [OR] = 31.06, P < .001; 30-39% vs 10%, OR = 7.84, P = 0.001) were more likely to be near a CHC and those with moderate rates of uninsurance (10%-19% vs <10%, OR = 0.42, P = .045) were less likely. Racial composition was not associated with proximity. Tracts close to a CHC were less likely (OR = 0.11, P < .0001) to be in a low access area. This association did not differ based on racial composition. Discussion: Although CHCs were more likely to be in areas with a greater fraction of racial minorities, location was more strongly influenced by public insurance rates. CHCs reduced the likelihood of being in low access areas but the effect did not vary by tract racial composition.
Modeling the internet of things: a hybrid modeling approach using complex networks and agent-based models
Authors: Batool Komal , Niazi Muaz A.
Published: March 2017

Sensors, coupled with transceivers, have quickly evolved from technologies purely confined to laboratory test beds to workable solutions used across the globe. These mobile and connected devices form the nuts and bolts required to fulfill the vision of the so-called internet of things (IoT). This idea has evolved as a result of proliferation of electronic gadgets fitted with sensors and often being uniquely identifiable (possible with technological solutions such as the use of Radio Frequency Identifiers). While there is a growing need for comprehensive modeling paradigms as well as example case studies for the IoT, currently there is no standard methodology available for modeling such real-world complex IoT-based scenarios. Here, using a combination of complex networks-based and agent-based modeling approaches, ​we present a novel approach to modeling the IoT. Specifically, the proposed approach uses the Cognitive Agent-Based Computing (CABC) framework to simulate complex IoT networks. We demonstrate modeling of several standard complex network topologies such as lattice, random, small-world, and scale-free networks. To further demonstrate the effectiveness of the proposed approach, we also present a case study and a novel algorithm for autonomous monitoring of power consumption in networked IoT devices. We also discuss and compare the presented approach with previous approaches to modeling. Extensive simulation experiments using several network configurations demonstrate the effectiveness and viability of the proposed approach.
Tutorial: Spectral bandwidth extension — Invention versus harmonic extrapolation
Authors: Liang Chen , Castagna John , Zavala Torres Ricardo
Published: March 2017

Various postprocessing methods can be applied to seismic data to extend the spectral bandwidth and potentially increase the seismic resolution. Frequency invention techniques, including phase acceleration and loop reconvolution, produce spectrally broadened seismic sections but arbitrarily create high frequencies without a physical basis. Tests in extending the bandwidth of low-frequency synthetics using these methods indicate that the invented frequencies do not tie high-frequency synthetics generated from the same reflectivity series. Furthermore, synthetic wedge models indicate that the invented high-frequency seismic traces do not improve thin-layer resolution. Frequency invention outputs may serve as useful attributes, but they should not be used for quantitative work and do not improve actual resolution. On the other hand, under appropriate circumstances, layer frequency responses can be extrapolated to frequencies outside the band of the original data using spectral periodicities determined from within the original seismic bandwidth. This can be accomplished by harmonic extrapolation. For blocky earth structures, synthetic tests show that such spectral extrapolation can readily double the bandwidth, even in the presence of noise. Wedge models illustrate the resulting resolution improvement. Synthetic tests suggest that the more complicated the earth structure, the less valid the bandwidth extension that harmonic extrapolation can achieve. Tests of the frequency invention methods and harmonic extrapolation on field seismic data demonstrate that (1) the frequency invention methods modify the original seismic band such that the original data cannot be recovered by simple band-pass filtering, whereas harmonic extrapolation can be filtered back to the original band with good fidelity and (2) harmonic extrapolation exhibits acceptable ties between real and synthetic seismic data outside the original seismic band, whereas frequency invention methods have unfavorable well ties in the cases studied.
Rock-physics diagnostics of an offshore gas field
Authors: Wollner Uri , Yang Yunfei , Dvorkin Jack P.
Published: March 2017

Seismic reflections depend on the contrasts of the elastic properties of the subsurface and their 3D geometry. As a result, interpreting seismic data for petrophysical rock properties requires a theoretical rock-physics model that links the seismic response to a rock’s velocity and density. Such a model is based on controlled experiments in which the petrophysical and elastic rock properties are measured on the same samples, such as in the wellbore. Using data from three wells drilled through a clastic offshore gas reservoir, we establish a theoretical rock-physics model that quantitatively explains these data. The modeling is based on the assumption that only three minerals are present: quartz, clay, and feldspar. To have a single rock-physics transform to quantify the well data in the entire intervals under examination in all three wells, we introduced field-specific elastic moduli for the clay. We then used the model to correct the measured shear-wave velocity because it appeared to be unreasonably low. The resulting model-derived Poisson’s ratio is much smaller than the measured ratio, especially in the reservoir. The associated synthetic amplitude variation with offset response appears to be consistent with the recorded seismic angle stacks. We have shown how rock-physics modeling not only helps us to correct the well data, but also allows us to go beyond the settings represented in the wells and quantify the seismic signatures of rock properties and conditions varying in a wider range using forward seismic modeling.
The diminishing residual matrices method for surface-consistent statics — A review
Authors: Gülünay Necati
Published: March 2017

The diminishing residual matrices (DRM) method can be used to surface-consistently decompose individual trace statics into source and receiver components. The statics to be decomposed may either be first-arrival times after the application of linear moveout associated with a consistent refractor as used in refraction statics or residual statics obtained by crosscorrelating individual traces with corresponding model traces (known as pilot traces) at the same common-midpoint (CMP) location. The DRM method is an iterative process like the well-known Gauss-Seidel (GS) method, but it uses only source and receiver terms. The DRM method differs from the GS method in that half of the average common shot and receiver terms are subtracted simultaneously from the observations at each iteration. DRM makes the under-constrained statics problem a constrained one by implicitly adding a new constraint, the equality of the contribution of shots and receivers to the solution. The average of the shot statics and the average of the receiver statics are equal in the DRM solution. The solution has the smallest difference between shot and receiver statics profiles when the number of shots and the number of receivers in the data are equal. In this case, it is also the smallest norm solution. The DRM method can be derived from the well-known simultaneous iterative reconstruction technique. Simple numerical tests as well as results obtained with a synthetic data set containing only the field statics verify that the DRM solution is the same as the linear inverse theory solution. Both algorithms can solve for the long-wavelength component of the statics if the individual picks contain them. Yet DRM method is much faster. Application of the method to the normal moveout-corrected CMP gathers on a 3D land survey for residual statics calculation found that pick-decompose-apply-stack stages of the DRM method need to be iterated. These iterations are needed because of time and waveform distortions of the pilot traces due to the individual trace statics. The distortions lessen at every external DRM iteration.
Inversion of the permeability of a tight gas reservoir with the combination of a deep Boltzmann kernel extreme learning machine and nuclear magnetic resonance logging transverse relaxation time spectrum data
Authors: Zhu Linqi , Zhang Chong , Wei Yang , Zhou Xueqing , Huang Yuyang , Zhang Chaomo
Published: March 2017

In view of the low accuracy of the existing nuclear magnetic-resonance (NMR) logging permeability model in tight sandstone reservoirs, we derive a relationship between the NMR [Formula: see text] spectrum and permeability based on the transverse relaxation theory of NMR and the Kozeny-Carman equation. We determined the reasons for the low accuracy of the model through the theoretical analysis. We have developed the deep Boltzmann kernel extreme learning machine (DBKELM) to improve the deep-learning algorithm and to predict the reservoir permeability based on NMR logging with a deep Boltzmann machine (DBM). We use the permeability data of 200 rock specimens in a tight gas reservoir in a certain area and the corresponding [Formula: see text] spectra from NMR logging for modeling. We apply the model to the evaluation of permeability in this area. The results show that the accuracy of the deep-learning algorithm is higher than that of the existing NMR logging permeability model and the shallow layer machine-learning model. Furthermore, the accuracy of the DBKELM that we have developed is higher than that of the DBM, which indicates that DBKELM is more suitable for the prediction of reservoir permeability. Therefore, deep-learning theory can be effectively used in oil exploration and development, and it can improve the interpretation accuracy of reservoir parameters. These findings contribute to the interpretation of reservoir parameters.

Purpose

The introduction of tyrosine kinase inhibitors has transformed the care of patients with chronic myeloid leukemia, with survival approaching that of healthy individuals. Current-day challenges in chronic myeloid leukemia care include adherence to tyrosine kinase inhibitor therapy. We studied adherence from resource-constrained settings and tried to analyze the factors responsible for nonadherence in these individuals. We also correlated adherence to current molecular status.

Patients and Methods

This was a single-center, cross-sectional, observational study from north India. It consisted of a questionnaire-based survey in which a one-to-one interview technique was used by trained nursing staff administering the Modified Morisky Adherence Scale (MMAS-9) questionnaire. Adherence was also measured on the basis of physician’s assessment. JMP 13.0.0 was used for statistical analysis.

Results

A total of 333 patients with a median age of 42 years were included in the study. The median BCR-ABL/ABL ratio (IS) was 0.175 (0.0 to 98.0). The mean MMAS-9 score was 11 ± 2. Adherence was seen in 54.95% on the basis of MMAS-9, whereas physician’s assessment reported adherence in 90.39% of patients. Using the χ2 test, no relationship was found between the two assessment techniques. There was a significant relationship between major molecular response status and adherence by physician’s assessment and MMAS-9 ( P < .001). Bivariate analysis by logistic fit showed a good relation between the MMAS-9 score and the BCR-ABL/ABL ratio (IS), χ2 (1,220) = 135.45 ( P < .001). On multivariate analysis, enrolment in the Novartis Oncology Access program (a patient assistance program) was significantly associated with adherence ( P = .012).

Conclusion

This study highlights the lack of adherence in real-world settings and the various factors responsible. Such studies are important from a public health services perspective in various settings around the world because they may lead to corrective action being taken at the institutional level.
Small-Volume Injections: Evaluation of Volume Administration Deviation From Intended Injection Volumes
Authors: Muffly Matthew K. , Chen Michael I. , Claure Rebecca E. , Drover David R. , Efron Bradley , Fitch William L. , Hammer Gregory B.
Published: March 2017

BACKGROUND:

In the perioperative period, anesthesiologists and postanesthesia care unit (PACU) nurses routinely prepare and administer small-volume IV injections, yet the accuracy of delivered medication volumes in this setting has not been described. In this ex vivo study, we sought to characterize the degree to which small-volume injections (≤0.5 mL) deviated from the intended injection volumes among a group of pediatric anesthesiologists and pediatric postanesthesia care unit (PACU) nurses. We hypothesized that as the intended injection volumes decreased, the deviation from those intended injection volumes would increase.

METHODS:

Ten attending pediatric anesthesiologists and 10 pediatric PACU nurses each performed a series of 10 injections into a simulated patient IV setup. Practitioners used separate 1-mL tuberculin syringes with removable 18-gauge needles (Becton-Dickinson & Company, Franklin Lakes, NJ) to aspirate 5 different volumes (0.025, 0.05, 0.1, 0.25, and 0.5 mL) of 0.25 mM Lucifer Yellow (LY) fluorescent dye constituted in saline (Sigma Aldrich, St. Louis, MO) from a rubber-stoppered vial. Each participant then injected the specified volume of LY fluorescent dye via a 3-way stopcock into IV tubing with free-flowing 0.9% sodium chloride (10 mL/min). The injected volume of LY fluorescent dye and 0.9% sodium chloride then drained into a collection vial for laboratory analysis. Microplate fluorescence wavelength detection (Infinite M1000; Tecan, Mannedorf, Switzerland) was used to measure the fluorescence of the collected fluid. Administered injection volumes were calculated based on the fluorescence of the collected fluid using a calibration curve of known LY volumes and associated fluorescence.

To determine whether deviation of the administered volumes from the intended injection volumes increased at lower injection volumes, we compared the proportional injection volume error (log
e
[administered volume/intended volume]) for each of the 5 injection volumes using a linear regression model. Analysis of variance was used to determine whether the absolute log proportional error differed by the intended injection volume. Interindividual and intraindividual deviation from the intended injection volume was also characterized.

RESULTS:

As the intended injection volumes decreased, the absolute log proportional injection volume error increased (analysis of variance, P < .0018). The exploratory analysis revealed no significant difference in the standard deviations of the log proportional errors for injection volumes between physicians and pediatric PACU nurses; however, the difference in absolute bias was significantly higher for nurses with a 2-sided significance of P = .03.

CONCLUSIONS:

Clinically significant dose variation occurs when injecting volumes ≤0.5 mL. Administering small volumes of medications may result in unintended medication administration errors.
Seten: a tool for systematic identification and comparison of processes, phenotypes, and diseases associated with RNA-binding proteins from condition-specific CLIP-seq profiles
Authors: Budak Gungor , Srivastava Rajneesh , Janga Sarath Chandra
Published: March 2017

RNA-binding proteins (RBPs) control the regulation of gene expression in eukaryotic genomes at post-transcriptional level by binding to their cognate RNAs. Although several variants of CLIP (crosslinking and immunoprecipitation) protocols are currently available to study the global protein–RNA interaction landscape at single-nucleotide resolution in a cell, currently there are very few tools that can facilitate understanding and dissecting the functional associations of RBPs from the resulting binding maps. Here, we present Seten, a web-based and command line tool, which can identify and compare processes, phenotypes, and diseases associated with RBPs from condition-specific CLIP-seq profiles. Seten uses BED files resulting from most peak calling algorithms, which include scores reflecting the extent of binding of an RBP on the target transcript, to provide both traditional functional enrichment as well as gene set enrichment results for a number of gene set collections including BioCarta, KEGG, Reactome, Gene Ontology (GO), Human Phenotype Ontology (HPO), and MalaCards Disease Ontology for several organisms including fruit fly, human, mouse, rat, worm, and yeast. It also provides an option to dynamically compare the associated gene sets across data sets as bubble charts, to facilitate comparative analysis. Benchmarking of Seten using eCLIP data for IGF2BP1, SRSF7, and PTBP1 against their corresponding CRISPR RNA-seq in K562 cells as well as randomized negative controls, demonstrated that its gene set enrichment method outperforms functional enrichment, with scores significantly contributing to the discovery of true annotations. Comparative performance analysis using these CRISPR control data sets revealed significantly higher precision and comparable recall to that observed using ChIP-Enrich. Seten's web interface currently provides precomputed results for about 200 CLIP-seq data sets and both command line as well as web interfaces can be used to analyze CLIP-seq data sets. We highlight several examples to show the utility of Seten for rapid profiling of various CLIP-seq data sets. Seten is available onhttp://www.iupui.edu/∼sysbio/seten/.

Published: March 2017

Background: Opportunities to use data and information to address challenges in international agricultural research and development are expanding rapidly. The use of agricultural trial and evaluation data has enormous potential to improve crops and management practices. However, for a number of reasons, this potential has yet to be realized. This paper reports on the experience of the AgTrials initiative, an effort to build an online database of agricultural trials applying principles of interoperability and open access. Methods: Our analysis evaluates what worked and what did not work in the development of the AgTrials information resource. We analyzed data on our users and their interaction with the platform. We also surveyed our users to gauge their perceptions of the utility of the online database. Results: The study revealed barriers to participation and impediments to interaction, opportunities for improving agricultural knowledge management and a large potential for the use of trial and evaluation data. Conclusions: Technical and logistical mechanisms for developing interoperable online databases are well advanced.  More effort will be needed to advance organizational and institutional work for these types of databases to realize their potential.

Incentives for Prosocial Behavior: The Role of Reputations
Authors: Exley Christine
Published: March 2017

Do monetary incentives encourage volunteering? Or, do they introduce concerns about appearing greedy and crowd out the motivation to volunteer? Since the importance of such image concerns is normally unobserved, the answer is theoretically unclear, and corresponding empirical evidence is mixed. To help counter this ambiguity, this paper proposes that the importance of image concerns—such as the desire to appear prosocial and not to appear greedy—relates to individuals’ volunteer reputations. Experimental results support this possibility. Individuals with past histories of volunteering are less responsive to image concerns if their histories are public, or if their prosocial tendencies are already known. Consistent with a decreased importance of appearing prosocial, they are less likely to volunteer. Consistent with a decreased importance of not appearing greedy, they are less likely to be discouraged by public incentives.

Abstract. Karyati, Ipor IB, Jusoh I, Wasli ME. 2017. The diameter increment of selected tree species in a secondary tropical forest in Sarawak, Malaysia. Biodiversitas 18: 304-311. The diameter at breast height (DBH) increments of dominant tree species in a secondary forest can determine forest growth in the area. This study was conducted to investigate the DBH increments of the nine dominant tree species in a secondary tropical forest. A total number of 180 trees representing nine species, seven genera, and six families were selected for the assessment of DBH increments during two years of study. Those nine species, namely: Acacia mangium Willd. (2.33 cm year-1), Endospermum diadenum (Miq.) Airy Shaw (1.05 cm year-1), Cratoxylum arborescens Blume. (0.96 cm year-1), Vernonia arborea Buch. Ham. (0.96 cm year-1), and Cratoxylum glaucum Korth. (0.80 cm year-1) had shown a high growth rate during the assessment, while the other four species such as Macaranga gigantea Mull. Arg., Macaranga triloba Mull. Arg., Euodia glabra (Bl.) Bl., and Vitex pubescens Vahl. had 0.53, 0.48, 0.37, and 0.30 cm year-1 in DBH increments, respectively. The average DBH increments for the entire selected species was 0.86 cm year-1 for periodic measurement and 0.75 cm year-1 for monthly measurement. This information is needed in order to understand the succession process in the secondary forests. It is important for the selection of the suitable species in a reforestation and a rehabilitation projects.

Abstract. Kothandaraman S, Sundarapandian S.2017. Structure of plant community in tropical deciduous forests of Kanyakumari Wildlife Sanctuary, India. Biodiversitas 18: 391-400. Plantcommunity structure of two tropical deciduous forest sites (I and II which are in different locations with different terrain characteristics viz., elevation and slope pattern) in Kanyakumari Wildlife Sanctuary, Western Ghats were assessed using standard phytosociological methods. Ten plots of 20 m x 20 m each were laid for woody species enumeration and 40 quadrats of 1 m x 1 m (4 in each plot) for understorey vegetation (herbs and plant species that are < 1 m in height) in each site. Overall, 76 plant species were recorded from 41 families, of which 23 contribute to understory. Site I (62) was twice as speciose as site II (31). Greater diversity index of adult woody vegetation was observed in site I (2.30) than site II (2.01). The woody individuals (diameter at breast height, DBH â‰¥ 10 cm) were more abundant in site I (518 individuals ha-1) than site II (448 individuals ha-1). The basal area of adult trees in sites I and II are 34.7 m2 ha-1 and 30.8 m2 ha-1 respectively. Euphorbiaceae was the most speciose family in both the sites. Twenty-five families in site I and seventeen families in site II were represented by singletons. Diameter class-wise distribution of adult trees showed a typical â€˜reverse J-shapedâ€™ curve indicating good regeneration status. Concerning understory, site I (19 species) has a greater diversity than site II (six species). The observed differences in the vegetation patterns between the two deciduous forest sites are possibly due to variations in elevation, terrain features and edaphic characteristics.

Published: March 2017

Abstract. Adie MM, Krisnawati A. 2017. Variability of pod trichome and agronomic characters of several soybean genotypes. Biodiversitas 18: 416-421. Trichome potentially act as a plant defense against soybean pod feeders, hence, the identification of trichome variability on soybean pod becomes increasingly important. A total of 150 soybean genotypes was identified for their pod trichome length and density. The experiment was conducted from February to June 2014. All soybean genotypes were planted in Muneng Research Station, Probolinggo (Indonesia). Identification of trichome length and density was performed in Laboratory of Biology, Malang State University. Soybean pods were taken from the third nodes at R7 stage. Soybean yield, pod trichome length and density were grouped using cluster analysis. The days to maturity varied from 72 to 83 days (average 77 days), 100 seed weight ranged from 12.50 to 23.50 g (average 16.50 g), seed yield ranged from 1.51 to 4.28 t/ha (average 2.90 t/ha), pod trichome length varied from 56.9 to 176.5 Âµm (average 112.8 Âµm), and trichome density ranged from 12 to 59 per 4 mm2 (average 27.64 per 4 mm2). Cluster analysis on 150 genotypes based on yield, trichome length, and trichome density classified soybean genotypes into five major groups. The first group consisted of 61 genotypes, and was characterized by sparse trichome. Cluster II consisted of genotypes with short trichome, whereas cluster III was characterized by medium trichome length and trichome density. Cluster IV and V, each consisted of six genotypes, and was characterized by dense and longer trichome, respectively. G511H/Arg//Arg///Arg///Arg-19-7 was the most densely pubescent genotype, while G511H/Anjasmoro//Anjasmoro-5-6 was the genotype with the longest trichome. These genotypes could be potentially be used as gene sources for further improvement of trichome length or trichome density in soybean varietal production.Keywords: Density, Glycine max, length, trichome

Abstract. Pesik A, EfendiD, NovariantoH, DinartiD, Sudarsono S. 2017. Development of SNAP markers based on nucleotide variability of WRKY genes in coconut and their validation using multiplex PCR. Biodiversitas 18: 465-475. Development of molecular markers benefits coconut breeding program. The availability of DNA sequences for coconuts opens the new possibility of developing molecular markers such as single nucleotide amplified polymorphism (SNAP). The study aimed to evaluate nucleotide sequence diversities of WRKY gene in the GenBank database, design gene specific primers for generating WRKY gene specific SNAP markers, optimize multiplex PCR technique and validate SNAP marker effectiveness for evaluating Kopyor coconut germplasm. Based on 35 sequences data of coconut WRKY genes that are available in the GenBank database, we have identified eight informative SNPs and used them to generate SNP-specific primers. We have designed sixteen primer pairs and validated them using singleplex PCR. Subsequently, we optimized the Ta and primer concentrations either for duplex or triplex PCR. Duplex PCR using two sets of primer pairs was more reliable for genotyping Kopyor coconut germplasm than triplex PCR. We have successfully demonstrated the duplex PCR for genotyping Banten Tall, Jember Tall, Kalianda Tall, Pati Dwarf and Sumenep Tall Kopyor coconuts. Therefore, one may use the developed SNAP markers as a simple alternative of co-dominant markers for genetic analysis of coconuts. One may use the developed SNAP markers to investigate the possible association between markers and Kopyor endosperm and other relevant phenotypes in coconuts.Keywords: Kopyor coconut, multiplex PCR, SNP

Prasetya CD, Syaufina L, Santosa G. 2017. The effect of various types of forest fires on pine resin productivity in GunungWalat University Forest, Sukabumi, Indonesia. Biodiversitas 18: 476-482. Gunung Walat University Forest (GWUF) of Sukabumi,Indonesia is one of pine resin producers that has 71 hectares of resin production area. The forest fire burned 7 hectares of resinproduction area in August 2015 was expected to affect the resin productivity. The aim of this study was to analyze the effect of eachtype of forest fire to pine resin productivity and analyze the correlation between the biophysic aspect and pine resin productivity afterthe fire. The types of forest fire were litter and shrub fire, stem fire, and crown fire. ANOVA test showed that the types of forest firehave significant effect to resin production with the value of Ftable (3.12)<Ftest (4.88) and Pvalue (0.006)<Î± (0.05). The Tukey test showed that thestem fire and the crown fire gave the most significant result to the resin production with the mean of resin productivity value (g/tree/day)respectively 24.54 and 21.698.

Hartati S, Nandariyah, Yunus A, Djoar DW. 2017. Cytological studies on black orchid hybrid (Coelogyne pandurata Lindley). Biodiversitas 18: 555-559. Black orchid (Coelogyne pandurata Lindley) is one of the rare species of Coelogyne Lindley, protected by the government of Indonesia. The cytological character of orchid is very important to study to support the success of breeding. The study aimed to assess the chromosomal number, karyotype pattern and ploidy level the hybrid of Black Orchid (Coelogyne pandurata). This study shows that the chromosomal number of the hybrid of Coelogyne pandurata (2n = 36) >< Coelogyne rumphii (2n = 72) is 2n = 54. Ploidy analysis by flow cytometry shows that hybrid shows triploid (2n = 3x = 54) different from the parent Coelogyne pandurata which is diploid (2n = 2x = 36) and the parent Coelogyne rumphii which is tetraploid (2n = 4x = 72). However, both parents and their hybrid performed the same karyotype pattern, which is metacentric. The chromosome size showed a variation in length from the longest Coelogyne pandurata 2.98 Â± 0.15 Âµm to the shortest Coelogyne rumphii 2.24 Â± 0.15 Âµm. The hybrids have a range of 2.50 Â± 0,10 Âµm to 2.85 Â± 0.10 Âµm. Karyotype patterns of black orchid (C. pandurata), C. rumphii and the hybridis metacentric.

Binur R, Pancoro A. 2017. Inbreeding depression level of post-larvae freshwater prawn (Macrobrachium rosenbergii) from several hatcheries in Java, Indonesia. Biodiversitas 18: 609-618. Inbreeding accumulation will tend to reduce genetic variation or depressed of the prawn fry produced. This problem has caused a decrease in production and quality of prawns culture in Indonesia. The purpose of this study is to measure the level of inbreeding depression prawn fry generated from several hatcheries in Java by microsatellite markers. There is four microsatellite locus to be used i.e Prk9A/T1, Prk4G/T1, TGFP16, and Mr8-88. The amplification of fourth locus using PCR with 6-carboxy-fluorescine (6-FAM) label. The number of alleles (Na) from fourth locus is Mr8-88 (11 alleles), TGFP16 (10 alleles), Prk4G/T1 (9 alleles), dan Prk9A/T1 (5 alleles), respectively. The level of polymorphism locus from highest to lowest is locus Prk4G/T1 (0.703), Prk9A/T1 (0.507), TGFP16 (0.410), and Mr8-88 (0.370), respectively. Inbreeding depression level of postlarvae (PL) M. rosenbergii tend to moderate with BBI Ciamis (He 0.444), BBUG Samas (He 0.514), LRPTBPAT Sukamandi (He 0.519), and UPBL Probolinggo (He 0.530), respectively. AMOVA analysis showed about 8.0% genetic variation among populations. From these results, it can be concluded that the PL produced indicated have been depressed. Post-larvae prawns produced from fourth hatcheries is not recommended to be a broodstock but can be used for cultivation for farmers.

O objetivo deste trabalho foi fazer um diagnóstico dos laticínios da região do Campo das Vertentes no estado de Minas Gerais, quanto à utilização do soro de leite, das perspectivas de mercado e averiguar obstáculos existentes à sua comercialização. O Brasil ocupa, no mundo, a quarta colocação em produção de queijos, sendo que a manufatura de queijos implica a geração de soro. O soro de leite é um subproduto nobre que merece atenção na sua utilização, pois é composto de proteínas, carboidratos, minerais e vitaminas. Para realização do trabalho foram selecionados laticínios produtores de queijo que possuem registro no Serviço de Inspeção Federal (SIF), situados na mesorregião do Campo das Vertentes, no estado de Minas Gerais. A partir da identificação do público alvo, que são os produtores de soro de leite, foi aplicado um questionário semiestruturado, com o objetivo de obter informações. A região do Campo das Vertentes é formada, em sua maioria, por laticínios de pequeno e médio porte, e o destino mais comum do soro de leite é para a alimentação animal e doação, devido à falta de interesse das indústrias ou pela falta de estrutura para aproveitar ou comercializar o produto. Concluiu-se que o aproveitamento do soro de leite pelo próprio laticínio ou a sua comercialização para terceiros, certamente é uma alternativa que, além de levar em consideração a preservação do meio ambiente, agrega valor econômico ao produto final. Pode-se perceber que existem barreiras para que esta prática seja viável.

A implementação de medidas preventivas de contaminações do leite com bactérias esporuladas é imprescindível considerando que esses microrganismos são produtores de enzimas proteolíticas e lipolíticas termoresistentes associadas a problemas tecnológicos como off flavors, coagulação doce e gosto amargo em leite e derivados, dentre outros. Dentre essas medidas, pode-se citar tipo de sanitizante e as condições de uso como concentração, tempo de contato e temperatura. Objetivou-se avaliar a eficiência de sanitizantes comumente empregados na indústria de laticínios sobre bactérias esporuladas isoladas de leite UHT. Empregou-se o teste de suspensão para avaliar a eficiência de soluções de hipoclorito de sódio, biguanida, ácido peracético e peróxido de hidrogênio sobre 18 estirpes de bactérias esporuladas do gênero Bacillus isoladas de leite UHT integral. Embora a maior ação sanitizante tenha sido observada para a biguanida, nenhum dos sanitizantes foi efetivo nas condições avaliadas, considerando que os valores médios observados de redução decimal (RD) foram inferiores a cinco ciclos logarítmicos ou a 99,999%. A efetividade de sanitizantes é um fator primordial para o controle de contaminações de natureza microbiana na indústria de laticínios. Assim, é fundamental a definição das condições ideais de uso destes produtos.

O objetivo deste estudo foi verificar se os rótulos das embalagens cartonadas de leite UHT (Ultra High Temperature) comercializados nos supermercados da cidade de Curitiba-PR estavam de acordo com as normas estabelecidas pelo Ministério da Agricultura, Pecuária e Abastecimento (MAPA). Foram avaliados 18 rótulos de leites UHT, industrializados sob regime de inspeção federal, comercializados nas principais redes de supermercados, quanto às normas de rotulagem constantes na legislação preconizada pelo MAPA. Foram realizadas visitas aos estabelecimentos e aplicação de um checklist contendo 26 itens, classificados em “conforme”, “não conforme” ou “não se aplica” em cada embalagem. Das marcas avaliadas, 16 (89%) apresentaram alguma não conformidade, incluindo em destaque a presença ou ausência de componentes intrínsecos ao produto e/ou a presença de componentes adicionados a todos os produtos de fabricação semelhante. O que mais chamou a atenção foi um dos produtos que apresentou na sua lista de ingredientes o pirofosfato dissódico, aditivo que pode ser utilizado na industrialização de produtos cárneos e de confeitaria, mas para o qual não foi encontrada norma indicando sua proibição, tão pouco que autorize sua utilização no leite UHT brasileiro, o que pode acarretar enganos no ato da compra, além de gerar falsas expectativas aos consumidores.
