Published: June 2019

We report on two new electrochemical sensors which, coupled to differential pulse voltammetry, constitutes a useful tool for diagnosis of heavy metal pollution. The electrochemical sensors AgHgNf/Cu and the AgBiNf/Cu were obtained by deposition of bimetallic particles of AgHg or AgBi on copper electrodes covered with a Nafion (Nf) film, respectively. Micrographs of the electrode’s surface showed evenly scattered bimetallic particles, with an approximate diameter of 150 nm, embedded in the Nafion (Nf) film. In order to test the electrodes, the hydrogen evolution signal according to the Brdička reaction was measured for the determination of cysteine-rich peptides (CRp) produced by plants. To check the accuracy of the electrodes, real samples of Nicotiana tabacum cells exposed to cytotoxic levels of cadmium were tested. The AgHgNf/Cu electrode produced detection limits (DLs) of 0.088 µmol L−1 for Cysteine and 0.139µmol L−1 for Glutathione, while for the AgBiNf/Cu electrode DLs were 0.41 µmol L−1 for cysteine and 0.244 µmol L−1 for glutathione. Thus, the new electrodes could be a useful analytical electrochemical system very convenient for fieldwork. The electrodes were capable of direct, accurate, and sensitive detection of synthesized peptides, despite the complex matrix where the Nicotiana tabacum cells were grown.

Authors: Szpyrka Ewa , Thomas Maciej , Podbielska Magdalena
Published: June 2019

The aim of this study was the modification and application of the QuEChERS method for the preparation and purification of samples in order to determine the level of captan in real wastewater originating from a plant protection products factory which was characterized by a significant content of organic substances [Chemical Oxygen Demand (COD) = 856 ± 128 mg O2/L and Total Organic Carbon (TOC) = 62 ± 9 mg/L]. The optimization of the method consisted of the selection of solvents used for the extraction of captan from wastewater and also sorbents used to purify the extracts by the dispersion of a solid phase extraction technique (dSPE). Two steps were used: extraction and clean-up. In the extraction step, acetonitrile was replaced by anacetonitrile:acetone mixture. In the clean-up step by the dSPE, five sorbents were tested: Florisil®, aluminum oxide (Al2O3), zirconium oxide (ZrO2), silicon oxide (SiO2) and PSA (primary and secondary amine). Concentrations of captan in wastewater extracts were determined by gas chromatography (GC) combined with electron capture detection (μECD). The best recovery parameters and precision of the method were obtained for samples purified using ZrO2 (recovery 98% and precision expressed as relative standard deviation RSD 8%) and Florisil® (recovery 96%, RSD 9%). Limits of detection (LOD) and quantification (LOQ) for determination of captan in diluted extract of wastewater were 0.003 and 0.01 mg/L, respectively. Matrix effects were in the range of −69% to −44% for samples purified by ZrO2 and Florisil®, respectively. The modified and optimized method was applied for fast and simple determination of captan levels in real industrial wastewater samples, in which the concentration of captan in diluted extract was determined to be 4.0 ± 0.3 mg/L.
Optoacoustic Calcium Imaging of Deep Brain Activity in an Intracardially Perfused Mouse Brain Model
Authors: Degtyaruk Oleksiy , Mc Larney Benedict , Deán-Ben Xosé , Shoham Shy , Razansky Daniel
Published: June 2019

One main limitation of established neuroimaging methods is the inability to directly visualize large-scale neural dynamics in whole mammalian brains at subsecond speeds. Optoacoustic imaging has advanced in recent years to provide unique advantages for real-time deep-tissue observations, which have been exploited for three-dimensional imaging of both cerebral hemodynamic parameters and direct calcium activity in rodents. Due to a lack of suitable calcium indicators excitable in the near-infrared window, optoacoustic imaging of neuronal activity at deep-seated areas of the mammalian brain has been impeded by the strong absorption of blood in the visible range of the light spectrum. To overcome this, we have developed and validated an intracardially perfused mouse brain preparation labelled with genetically encoded calcium indicator GCaMP6f that closely resembles in vivo conditions. By overcoming the limitations of hemoglobin-based light absorption, this new technique was used to observe stimulus-evoked calcium dynamics in the brain at penetration depths and spatio-temporal resolution scales not attainable with existing neuroimaging techniques.
High Concentration Photovoltaics (HCPV) with Diffractive Secondary Optical Elements
Authors: Sahin Furkan , Yılmaz Musa
Published: June 2019

Multi-junction solar cells can be economically viable for terrestrial applications when operated under concentrated illuminations. The optimal design of concentrator optics in high concentration photovoltaics (HCPV) systems is crucial for achieving high energy conversion. At a high geometric concentration, chromatic aberration of the primary lens can restrict the optical efficiency and acceptance angle. In order to correct chromatic aberration, multi-material, multi-element refractive elements, hybrid refractive/diffractive elements, or multi-element refractive and diffractive systems can be designed. In this paper, the effect of introducing a diffractive surface in the optical path is analyzed. An example two-stage refractive and diffractive optical system is shown to have an optical efficiency of up to 0.87, and an acceptance angle of up to ±0.55° with a 1600× geometric concentration ratio, which is a significant improvement compared to a single-stage concentrator system with a single material. This optical design can be mass-produced with conventional fabrication methods, thus providing a low-cost alternative to other approaches, and the design approach can be generalized to many other solar concentrator systems with different cell sizes and geometric concentration ratios.

Authors: Wojdyło Aneta , Nowicka Paulina , Teleszko Mirosława
Published: June 2019

The aim of this study was to characterize in detail 25 sour cherry cultivars and provide data on their industrial processing into high-quality sour cherry cloudy juices (ScCJ). Anthocyanin composition was identified and quantified by LC-PDA-ESI-MS QTof, UPLC-PDA. Kinetic degradation (k × 103, t1/2, D value) and color (CIE La*b*) were measured before and after 190 days of storage at 4 °C and 30 °C. A total of five anthocyanins, four cyanidins (-3-O-sophoroside, -3-O-glucosyl-rutinoside, -3-O-glucoside, and -3-O-rutinoside) and one peonidin-3-O-rutinoside were detected across all investigated juices. Total anthocyanin content ranged from ~590 to ~1160 mg/L of juice, with the highest levels in Skierka, Nagy Erdigymulscu, Wilena, Wiblek, and Safir cvs., and the lowest in Dradem and Nanaones. During 190 days of storage a significant change was observed in the content of anthocyanins. Their degradation depended rather on the storage conditions (time and temperature) than on the type of anthocyanin compounds present in the ScCJ. Half-life values of ScCJ ranged from 64.7 to 188.5 days at 4 °C and from 45.9 to 112.40 days at 30 °C. Sample redness changed more rapidly than yellowness or lightness and Chroma or hue angel. These results may be useful for the juice industry and serve as a starting point for the development of tasty sour cherry juices with high levels of bioactive compounds.
Development of a Two-Stage ESS-Scheduling Model for Cost Minimization Using Machine Learning-Based Load Prediction Techniques
Authors: Park Minsu , Kim Jaehwi , Won Dongjun , Kim Jaehee
Published: June 2019

Effective use of energy storage systems (ESS) is important to reduce unnecessary power consumption. In this paper, a day-ahead two-stage ESS-scheduling model based on the use of a machine learning technique for load prediction has been proposed for minimizing the operating cost of the energy system. The proposed algorithm consists of two stages of ESS. In the first stage, ESS is used to minimize demand charges by reducing the peak load. Then, the remaining capacity is used to reduce energy charges through arbitrage trading, thereby minimizing the total operating cost. To achieve this purpose, accurate load prediction is required. Machine learning techniques are promising methods owing to the ability to improve forecasting performance. Among them, ensemble learning is a well-known machine learning method which helps to reduce variance and prevent overfitting of a model. To predict loads, we employed bootstrap aggregating (bagging) or random forest technique-based decision trees after Holt–Winters smoothing for trends. Our combined method can increase the prediction accuracy. In the simulation conducted, three combined prediction models were evaluated. The prediction task was performed using the R programming language. The effectiveness of the proposed algorithm was verified by using Python’s PuLP library.
Medical Aesthetics in the Twilight of Empire: Lungrik Tendar and The Stainless Vaiḍūrya Mirror
Authors: King Matthew W.
Published: June 2019

This article introduces the life and medical histories of the luminary Khalkha Mongolian monk, Lungrik Tendar (Tib. Lung rigs bstan dar; Mon. Lungrigdandar, c. 1842–1915). Well known for his exegesis of received medical works from Central Tibet, Lungrik Tendar was also a historian of the Four Tantras (Tib. Rgyud bzhi; Mon. Dörben ündüsü). In 1911, just as Khalkha Mongolia began separating from a flailing Qing Empire, Lungrik Tendar set out to append the story of Mongolia and of Mongolian medicine, political formation, and religious life to the Four Tantra’s well-known global histories. In addition, he provided an illuminating summary of how to present the Four Tantras to a popular audience in the twilight of the imperial period. This article introduces the life of Lungrik Tendar and analyzes his previously unstudied medical history from 1911, The Stainless Vaiḍūrya Mirror. On the basis of this understudied text, this article explores ways that monastic medicine in the frontier scholastic worlds of the late-Qing Empire were dependent upon aesthetic representations of space and time and of knowledge acquisition and practice, and how such medical aesthetics helped connect the religious, political, legal, economic, and social worlds of Asia’s heartland on the eve of nationalist and socialist revolution and state-directed erasure.
Paraspinal Muscle Segmentation Based on Deep Neural Network
Authors: Li Haixing , Luo Haibo , Liu Yunpeng
Published: June 2019

The accurate segmentation of the paraspinal muscle in Magnetic Resonance (MR) images is a critical step in the automated analysis of lumbar diseases such as chronic low back pain, disc herniation and lumbar spinal stenosis. However, the automatic segmentation of multifidus and erector spinae has not yet been achieved due to three unusual challenges: (1) the muscle boundary is unclear; (2) the gray histogram distribution of the target overlaps with the background; (3) the intra- and inter-patient shape is variable. We propose to tackle the problem of the automatic segmentation of paravertebral muscles using a deformed U-net consisting of two main modules: the residual module and the feature pyramid attention (FPA) module. The residual module can directly return the gradient while preserving the details of the image to make the model easier to train. The FPA module fuses different scales of context information and provides useful salient features for high-level feature maps. In this paper, 120 cases were used for experiments, which were provided and labeled by the spine surgery department of Shengjing Hospital of China Medical University. The experimental results show that the model can achieve higher predictive capability. The dice coefficient of the multifidus is as high as 0.949, and the Hausdorff distance is 4.62 mm. The dice coefficient of the erector spinae is 0.913 and the Hausdorff distance is 7.89 mm. The work of this paper will contribute to the development of an automatic measurement system for paraspinal muscles, which is of great significance for the treatment of spinal diseases.

Published: June 2019

Zearalenone (ZEA) is a prevalent mycotoxin with high toxicity in animals. In order to study its effect on juvenile grass carp (Ctenopharyngodon idella), six diets supplemented with different levels of ZEA (0, 535, 1041, 1548, 2002, and 2507 μg/kg diet) for 10 weeks were studied to assess its toxicity on intestinal structural integrity and potential mechanisms of action. Our report firstly proved that ZEA led to growth retardation and body deformity, and impaired the intestinal structural integrity of juvenile grass carp, as revealed by the following findings: (1) ZEA accumulated in the intestine and caused histopathological lesions; (2) ZEA resulted in oxidative injury, apoptosis, and breached tight junctions in the fish intestine, which were probably associated with Nuclear factor-erythroid 2-related factor 2 (Nrf2), p38 mitogen activated protein kinases (p38MAPK), and myosin light chain kinase (MLCK) signaling pathways, respectively. ZEA had no influence on the antioxidant gene levels of Kelch-like ECH associating protein 1 (Keap1)b (rather than Keap1a), glutathione-S-transferase (GST)P1, GSTP2 (not in the distal intestine (DI)), tight junctions occludin, claudin-c (not in the proximal intestine (PI)), or claudin-3c (not in the mid intestine (MI) or DI).

Published: June 2019

Background: Flexuous rod-shape nanoparticles—made of the coat protein of papaya mosaic virus (PapMV)—provide a promising vaccine platform for the presentation of viral antigens to immune cells. The PapMV nanoparticles can be combined with viral antigens or covalently linked to them. The coupling to PapMV was shown to improve the immune response triggered against peptide antigens (<39 amino acids) but it remains to be tested if large proteins can be coupled to this platform and if the coupling will lead to an immune response improvement. Methods: Two full-length recombinant viral proteins, the influenza nucleoprotein (NP) and the simian immunodeficiency virus group-specific protein antigen (GAG) were coupled to PapMV nanoparticles using sortase A. Mice were immunized with the nanoparticles coupled to the antigens and the immune response directed to the antigens were analyzed by ELISA and ELISPOT. Results: We showed the feasibility of coupling two different full-length proteins (GAG and NP) to the nanoparticle. We also showed that the coupling to PapMV nanoparticles improved significantly the humoral and the cytotoxic T lymphocyte (CTL) immune response to the antigens. Conclusion: This proof of concept demonstrates the versatility and the efficacy of the PapMV vaccine platform in the design of vaccines against viral diseases.

THE PARADIGMATIC ROLE OF GENESIS 3 FOR READING BIBLICAL NARRATIVE ABOUT DESIRE
Authors: TUSHIMA CEPHAS
Published: June 2019

The biblical Hebrew texts of sexual politics (often involving sordid sexual violence, especially against women) have been studied in the last forty years with an ideological bent that employs contemporary literary analysis. This essay is an attempt to allow the biblical text to furnish strategies for reading its troubling narratives rather than imposing external ideologies over it. An ethical narrative close reading of the text of primeval desire (Gen 3) led me to the discovery of four themes—desire, particularly its derivative, sexual passion; power-play; alterity; and peril— and to the biblical authors’ characterization of God in divine response to human deviant behavior as heuristic tools for reading these texts of desire.
HOW THE DWELLING BECOMES A TENT OF MEETING: A THEOLOGY OF LEVITICUS
Authors: MORALES L. MICHAEL
Published: June 2019

This essay proposes that the theology of the book of Leviticus centers on the question of how the dwelling, God’s mishkan, becomes a tent of meeting, the ’ohel mo‘ed. By the end of Leviticus, the tent of meeting has become the place where Israel’s community can enjoy fellowship with Yahweh—a Sabbath goal symbolically portrayed in Leviticus 24:1–9. The cultic festivals of Leviticus 23–25, with 24:1–9 at their heart, demonstrate that the dwelling has become a “tent of meeting” indeed and that the purpose for the cosmos—namely, fellowship with God—can now be realized through Israel’s cultus.

ДО ПРОБЛЕМИ РОЗВИТКУ ЕМОЦІЙНОГО ІНТЕЛЕКТУ ОСОБИСТОСТІ
Authors: Стельмашук Жанна Григорівна
Published: June 2019

У статті на основі здійсненого теоретичного аналізу розкрито сутність  феномену емоційного інтелекту як особливого конструкта та здатності особистості.

Приділено увагу вітчизняним та зарубіжним концепціям у розумінні емоційного інтелекту, їх спільним та відмінним позиціям стосовно його структури та ґенези розвитку.

Доведено, що термін «емоційний інтелект» розглядається як здатність до розпізнання, розуміння емоцій і управління ними; служить для визначення сукупності здібностей, знань та вмінь, пов’язаних з регуляцією емоційної сфери особистості, необхідних для успішної соціалізації та комунікації.

Схарактеризовано дві форми репрезентації поняття «емоційний інтелект»: міжособистісний емоційний інтелект (спроможність людини розуміти інших людей, усвідомлювати мотиви їхньої діяльності, ставлення їх до роботи, вирішувати, як краще співпрацювати з цими людьми) та  внутрішньоособистісний емоційний інтелект (властивість людини, спрямована на себе: спроможність формувати точну адекватну модель власного «я» та використовувати цю модель, щоб ефективно функціонувати у житті).

Обґрунтовано доцільність розглядати емоційний інтелект як інтегральну властивість особистості, що забезпечує здатність розуміти емоції та управляти ними через когнітивну обробку емоційної інформації.

Зроблено висновок, що емоційний інтелект як наскрізне уміння учня Нової української школи знайшло своє обґрунтування у наукових дослідженнях з психології, але є практично недослідженим у педагогічній теорії та практиці.

The rational design and synthesis of covalent triazine frameworks (CTFs) from defined dicyano-aryl building blocks or their binary mixtures is of fundamental importance for a judicious tuning of the chemico-physical and morphological properties of this class of porous organic polymers. In fact, their gas adsorption capacity and their performance in a variety of catalytic transformations can be modulated through an appropriate selection of the building blocks. In this contribution, a set of five CTFs (CTF1–5) have been prepared under classical ionothermal conditions from single dicyano-aryl or heteroaryl systems. The as-prepared samples are highly micro-mesoporous and thermally stable materials featuring high specific surface area (up to 1860 m2·g−1) and N content (up to 29.1 wt %). All these features make them highly attractive samples for carbon capture and sequestration (CCS) applications. Indeed, selected polymers from this series rank among the CTFs with the highest CO2 uptake at ambient pressure reported so far in the literature (up to 5.23 and 3.83 mmol·g−1 at 273 and 298 K, respectively). Moreover, following our recent achievements in the field of steam- and oxygen-free dehydrogenation catalysis using CTFs as metal-free catalysts, the new samples with highest N contents have been scrutinized in the process to provide additional insights to their complex structure–activity relationship.

We present a statistical analysis of the first 300 stars observed by the Gemini Planet Imager Exoplanet Survey. This subsample includes six detected planets and three brown dwarfs; from these detections and our contrast curves we infer the underlying distributions of substellar companions with respect to their mass, semimajor axis, and host stellar mass. We uncover a strong correlation between planet occurrence rate and host star mass, with stars M

Jup and semimajor axes of 3–100 au at 99.92% confidence. We fit a double power-law model in planet mass (m) and semimajor axis (a) for planet populations around high-mass stars (M

, finding α = −2.4 ± 0.8 and β = −2.0 ± 0.5, and an integrated occurrence rate of

% between 5–13M
Jup and 10–100 au. A significantly lower occurrence rate is obtained for brown dwarfs around all stars, with

% of stars hosting a brown dwarf companion between 13–80M
Jup and 10–100 au. Brown dwarfs also appear to be distributed differently in mass and semimajor axis compared to giant planets; whereas giant planets follow a bottom-heavy mass distribution and favor smaller semimajor axes, brown dwarfs exhibit just the opposite behaviors. Comparing to studies of short-period giant planets from the radial velocity method, our results are consistent with a peak in occurrence of giant planets between ∼1 and 10 au. We discuss how these trends, including the preference of giant planets for high-mass host stars, point to formation of giant planets by core/pebble accretion, and formation of brown dwarfs by gravitational instability.

Published: June 2019

We investigate the evolution of the suprathermal (ST) proton population as interplanetary shocks cross 1 au. The variability of the ST proton intensities and energy spectra upstream of the shocks is analyzed in terms of the shock parameters, upstream magnetic field configurations, and preexisting upstream populations. Propitious conditions for the observation of ST particles at distances far upstream from the shock occur in parallel shock configurations when particles can easily escape from the shock vicinity. In this situation, ST intensity enhancements show onsets characterized by velocity dispersion effects and energy spectra that develop into a “hump” profile peaking around ∼10 keV just before the arrival of the shock. The observation of field-aligned proton beams at low energies (5–10 keV) is possible under conditions that facilitate the scatter-free propagation of the particles streaming out of the shock. Upstream of perpendicular shocks, ST intensity enhancements are only observed in close proximity to the shock. Power-law proton spectra develop downstream of the shocks. The functional form for the downstream phase-space density proportional to v
−5 is observed only over a limited range of ST energies. The absence of ST populations observed far upstream of interplanetary shocks raises questions about whether ST protons contribute as a seed particle population in the processes of particle acceleration at shocks.

We report on the discovery of a white dwarf companion to the nearby late G dwarf star, HD 159062. The companion is detected in 14 years of precise radial velocity (RV) data, and in high-resolution imaging observations. RVs of HD 159062 from 2003 to 2018 reveal an acceleration of −13.3 ± 0.12

, indicating that it hosts a companion with a long-period orbit. Subsequent imaging observations with the ShaneAO system on the Lick Observatory 3 m Shane telescope, the PHARO AO system on the Palomar Observatory 5 m telescope, and the NIRC2 AO system at the Keck II 10 m telescope reveal a faint companion 2.″7 from the primary star. We performed relative photometry, finding ΔJ = 10.09 ± 0.38 mag,

mag, and

mag for the companion from these observations. Analysis of the radial velocities, astrometry, and photometry reveals that the combined data set can only be reconciled for the scenario where HD 159062 B is a white dwarf. A full Bayesian analysis of the RV and imaging data to obtain the cooling age, mass, and orbital parameters of the white dwarf indicates that the companion is an old

white dwarf with an orbital period of

yr, and a cooling age of

Gyr.

Published: June 2019

Whistler waves are intermittently present in the solar wind, while their origin and effects are not entirely understood. We present a statistical analysis of magnetic field fluctuations in the whistler frequency range (above 16 Hz) based on about 801,500 magnetic field spectra measured over 3 yr aboard the Artemis spacecraft in the pristine solar wind. About 13,700 spectra (30 hr in total) with intense magnetic field fluctuations satisfy the interpretation in terms of quasi-parallel whistler waves. We provide estimates of the whistler wave occurrence probability, amplitudes, frequencies, and bandwidths. The occurrence probability of whistler waves is shown to strongly depend on the electron temperature anisotropy. The whistler wave amplitudes are in the range from about 0.01 to 0.1 nT and typically below 0.02 of the background magnetic field. The frequencies of the whistler waves are shown to be below an upper bound that is dependent on β

e
. The correlations established between the whistler wave properties and local macroscopic plasma parameters suggest that the observed whistler waves can be generated in local plasmas by the whistler heat flux instability. The whistler wave amplitudes are typically small, which questions the hypothesis that quasi-parallel whistler waves are capable to regulate the electron heat flux in the solar wind. We show that the observed whistler waves have sufficiently wide bandwidths and small amplitudes, so that effects of the whistler waves on electrons can be addressed in the frame of the quasi-linear theory.
Two-step Evolution of a Rising Flux Rope Resulting in a Confined Solar Flare

Published: June 2019

Combining the Solar Dynamics Observatory and the New Vacuum Solar Telescope observations, we study a confined flare triggered by a rising flux rope within the trailing sunspots of active region 12733. The flux rope lying above the sheared polarity inversion line can be constructed through magnetic extrapolation but could not be detected in multiwavelength images at the pre-flare stage. The conspicuous shearing motions between the opposite-polarity fields in the photosphere are considered to be responsible for the flux rope formation. The maximum twist of the flux rope is as high as −1.76, and then the flux rope rises due to the kink instability. Only when the flare starts can the flux rope be observed in high-temperature wavelengths. The differential emission measure results confirm that this flux rope is a high-temperature structure. Associated with the rising flux rope, there appear many post-flare loops and a pair of flare ribbons. When the rising flux rope meets and reconnects with the large-scale overlying field lines, a set of large-scale twisted loops are formed, and two flare ribbons propagating in opposite directions appear on the outskirts of the former ribbons, indicating that the twist of the flux rope is transferred to a much larger system. These results imply that the external reconnection between the rising flux rope and the large-scale overlying loops plays an important role in the confined flare formation.

We present the first radio polarimetric observations of a fast-rising blue optical transient, AT2018cow. Two epochs of polarimetry with additional coincident photometry were performed with the Atacama Large Millimeter/submillimeter Array. The overall photometric results based on simultaneous observations in the 100 and 230 GHz bands are consistent with the nonthermal radiation model reported by Ho et al. and indicate that the spectral peaks (∼110 GHz at the first epoch and ∼67 GHz at the second epoch) represent the synchrotron self-absorption frequency. The non-detection of linear polarization with <0.15% in the 230 GHz band at the phase when the effect of synchrotron self-absorption was quite small in the band may be explained by internal Faraday depolarization with high circumburst density and strong magnetic field. This result supports the stellar explosion scenario rather than the tidal disruption model. The maximum energy of accelerating particles at the shocks of AT2018cow-like objects is also discussed.

Introduction: Salmonella is a major cause of foodborne illness throughout the world. The use of quantitative techniques is important for assessing the risk and determining the capacity of each step of the slaughtering process to decrease or increase bacterial contamination. We aimed to detect and to quantify the presence of Salmonella in Brazilian processing plants by real-time quantitative polymerase chain reaction (qPCR).

Methodology: A total of 139 poultry slaughterhouses samples were collected in order to detect to and quantify Salmonella by qPCR.

Results: Almost all collection points (3/18), except water from pre-chiller tank, carcasses after pre-chiller, and carcasses frozen at -12ºC for 60 days, and 49% (68/139) of samples were positive for Salmonella. Quantification means varied equally among all of the tested sources, and we could not establish any pattern of variation. A large proportion (52.6%) of cloacal swabs was Salmonella-positive. Also, contamination in transport cages was increased after the cleaning process, indicating that the process was ineffective. The overall prevalence in samples obtained during the slaughtering process was 48.9%, and on the whole rinsed carcasses, this proportion was 50%. The detection of Salmonella in frozen carcasses, even after long periods of storage, indicates that the carcasses are a potential source of infection for consumers.

Conclusions: We found that contamination levels remain similar throughout the slaughtering. qPCR proved to be an efficient method for the detection of Salmonella.

Introduction: The interleukin 28B (IL28B) genotype is associated with changes of lipid metabolism in patients infected with hepatitis C virus (HCV). The association of steatosis with serum levels of adiponectin in chronic hepatitis C (CHC) patients has also been documented. This study aimed for the evaluation of serum levels of IL28B and adiponectin as well as the association of IL28B SNPs with different clinicopathological parameters in HCV-infected patients.

Methodology: All 142 HCV-infected patients received peg-interferon plus ribavirin. Detection of rs8099917 and rs12979860 IL-28B genotypes was done with specific primers. Serum IL28 and adiponectin levels were measured using commercial ELISA kits.

Results: Higher levels of both IL28 and adiponectin were found in patients. In Genotype 3a (G3a) -infected patients, IL28 and adiponectin serum levels were significantly higher than those infected with G1a. A correlation was found between increasing levels of AST and ALT in G3a-infected patients and the decrease in IL28 and adiponectin serum levels, respectively, in contrast to G1a-infected patients. Higher levels of both IL28 and adiponectin were associated with both CT allele of rs12979860 and TT allele of rs8099917 in patients in comparison with corresponding alleles in controls.

Conclusions: In contrast to other studies, this study showed higher serum adiponectin levels in HCV-infected patients compared to that in healthy controls. This finding is possibly due to adiponectin resistance caused by down-regulation of adiponectin receptors or tumorigenic effects of adiponectin. Our genotype-based analyses revealed, at least in part, the involvement of the viral factors in the outcome of HCV infection.

Introduction: European cultural norms have influenced physicians’ attire in Sri Lanka. The necktie is one such item of clothing which is worn to be recognized and respected as professionals. This study was carried out to assess the perceptions of doctors and patients towards male doctors wearing neckties while providing patient care.

Methododology: A descriptive cross-sectional study was carried out at the National Hospital of Sri Lanka. An interviewer-administered questionnaire was used to collect data from doctors and patients.

Results: The study included 105 doctors (57% males) and 333 patients (54% males). Mean ages of the doctors and patients were 37 years (95% C.I. 36-39) and 47 years (95% C.I. 45-49) respectively. Sixty-nine percent of the patients had completed secondary education or above. None of the patients were aware of the risk of spreading infections by wearing a necktie. Of the 41% of doctors who thought it was unnecessary to wear a necktie, 95% believed the necktie can spread infections. Ninety-five percent of patients believed doctors should wear neckties to be identified and respected and to maintain trustworthiness.

Conclusions: None of the patients were aware of the possible risk of spreading infections by wearing a necktie, while most of the doctors who thought neckties were unnecessary also believed neckties can spread infections. Almost all patients thought that doctors should wear a necktie to be recognized and respected. Therefore, implementing a change in dress policy for doctors is a challenging task in Sri Lanka.
Introduction to the Symposium: Improving access to hidden scientific data in the Biodiversity Heritage Library
Authors: Rinaldo Constance
Published: June 2019

This will be a short introduction to the symposium: Improving access to hidden scientific data in the Biodiversity Heritage Library. The symposium will present examples of how the Biodiversity Heritage Library (BHL) collaborates across the international consortium and with community partners around the world to help enhance access to the biodiversity literature. Literature repositories, particularly the BHL collections, have been recognized as critical to the global scientific community. A diverse global user community propels BHL and BHL users to develop access tools beyond the standard “title, author, subject” search. BHL utilizes the Global Names Recognition and Discovery (GNRD) service to identify taxonomic names within text rendered by Optical Character Recognition (OCR) software, enabling scientific name searches and creation of species-specific bibliographies, critical to systematics research. In this symposium, we will hear from international partners and creative users making data from the BHL globally accessible for the kinds of larger-scale analysis enabled by BHL’s full-text search capabilities and Application Program Interface (API) protocols. In addition to taxonomic name services already incorporated in BHL, the consortium has also begun exploring georeferencing strategies for better searching and potential connections with key biodiversity resources such as the Global Biodiversity Information Facility (GBIF). With many different institutions around the world participating, the ability to work together virtually is critical for a seamless end product that meets the demands of the international community as well as the needs of local institutions.
