Symptoms of characteristic rot was observed on jackfruits (Artocarpus heterophyllus) of Thrissur district in Kerala. This study investigates, the symptomatology, pathogenicity and identification of the causal organism for fruit rot disease. The isolation of fungal sample was obtained from Thrissur district during the month of November 2023. The isolated fungus was successfully grown on potato dextrose agar medium and was characterized. Based on its cultural, morphological traits and molecular characterization, the fungus was identified as Agroathelia rolfsii (teleomorph: Athelia rolfsii, anamorph: Sclerotium rolfsii). In the molecular characterization by amplifying internal transcribed spacer (ITS) region using the ITS1 and ITS4 primer pair, the isolate TK2 showed high per cent identity of 99.35 per cent and query coverage 100 per cent with Agroathelia rolfsii in blastN search. Phylogenetic analysis of the internal transcribed spacer (ITS) and large subunit (LSU) genes played a key role in confirming the species identity. Athelia rolfsii has been reported for the first time to cause fruit rot disease on jackfruit, from Thiruvananthapuram by Sajeena et al. [1]. This study reports the infection of Agroathelia rolfsii, on jackfruit from Thrissur district. These soil-borne pathogen can spread easily and stay dormant in soil in the form of sclerotium for long time, hence it is essential to improve the management strategies and prevent its spread to other crops, for that further studies need to be conducted. This study was conducted at Department of Plant Pathology, College of Agriculture, Vellanikkara, Thrissur, Kerala between November 2023 and June 2024.

Abstract

Objective
The aim of the study was to determine and compare the prevalence of cytomegalovirus (CMV) and Epstein-Barr virus (EBV) antibodies and DNA among nurses working in different profiles of healthcare activity.

Material and methods
The study population comprised 120 women (90 exposed healthcare workers and 30 controls). Blood samples were investigated using chemiluminescent microparticle immunoassays (CMIA) tests to detect the presence of EBV VCA IgM, IgG, and CMV IgM, IgG. Plasma CMV and EBV DNA levels were assessed using real-time polymerase chain reaction (PCR).

Results
CMV IgG antibodies were present in 87.80% nurses (86.70% in controls), EBV IgG were present in all the nurses studied and in the control group. No statistically significant differences were noted between the subgroups of nurses and the control group as regards IgG CMV, VCA IgG EBV. CMV IgM/EBV IgM antibodies were negative in all the nurses. CMV/EBV DNA was reported only in the study group. It was not found in any of control group participants.

Conclusions
The positive PCR CMV/EBV markers only in the study group can be indicative of the exposure of nurses to these pathogens being greater than in other people not being professionally involved in patient care. In addition, it was observed that the level of CMV IgG antibodies as well as EBV VCA IgG antibodies tended to be linked to the age and the length of work of nurses working in pediatrics.

Published: February 2020

AbstractAlfalfa (Medicago sativa) growers in the southwestern United States desire to match irrigation allocations better and to recover at least some of the establishment costs in the seeding year by spring planting. Randomized complete block studies at Tucumcari and Los Lunas, NM compared planting date effects on seeding year and subsequent production year yields and seeding year economics. Seeding year yields in each test were statistically separated by the number of harvests taken. The earliest planting at Los Lunas produced 11.3 Mg ha−1 over three harvests in the seeding year to fully recover establishment and harvesting costs, and two harvests (4.3 Mg ha−1) from the earliest planting at Tucumcari recovered approximately half the costs. Production year yields from spring and late‐summer to early autumn seedings at Los Lunas were generally not different, but greater than 25 June and 21 July plantings (2‐yr mean yields for 12 May, 1 June, 25 June, 21 July, 11 August, 2 September, and 25 September planting dates were 22.8, 22.1, 20.5, 21.2, 23.3, 21.8, and 22.5 Mg ha−1, respectively; P < .0001, SEM = 0.4). Four‐year average production year yields at Tucumcari were statistically separated into spring, early to mid‐summer, and late summer plantings (12.8, 10.8, 10.1, 11.1, 8.8, and 8.7 Mg ha−1 4‐yr mean yields for 5 June, 26 June, 17 July, 7 August, 28 August, and 18 September planting dates, respectively; P < .0001, SEM = 0.8). Spring planting can potentially increase seeding year yields as well as throughout the stand life.
Longitudinal Neuroimaging over 30 Days: Temporal Characteristics of Migraine
Authors: Schulte Laura H. , Mehnert Jan , May Arne 
Published: February 2020

ObjectiveAlthough migraine is defined by the headache and headache‐associated symptoms, the true beginning of a migraine attack lies in the premonitory phase. To understand the generation of attacks, one needs to investigate the phase before headache starts. The premonitory phase of migraine is characterized by a well‐described complex of symptoms. Its duration, however, is not clearly defined, and there are no biomarkers to help define when this phase starts.MethodsHere, we used functional magnetic resonance imaging (MRI) to elucidate the duration of the premonitory phase in spontaneous human migraine attacks. Because migraine attacks are hardly predictable and thereby the premonitory phase is difficult to catch, we scanned 9 patients daily over a minimum period of 30 days using a well‐established paradigm for functional MRI of trigeminal nociception.ResultsSeven patients were included in the analysis, thus providing cumulative data of 27 spontaneous human migraine attacks including scans before, during, and after migraine pain as well as interictal scans. As a response to painful trigeminal stimulation, activation of the hypothalamus was present within the last 48 hours before headache onset but not earlier.InterpretationUsing hypothalamic activation as a potential marker for the premonitory phase of migraine in this unique dataset, our data corroborated a duration of 48 hours for the premonitory phase of migraine. We suggest applying this time criterion in future studies when focusing on this phase of the migraine cycle. ANN NEUROL 2020;87:646–651

Published: February 2020

AbstractThe combination of supramolecular chemistry and soft colloids as microgels represents an ambitious way to develop multi‐versatile colloidal assemblies. Hereafter, terpyridine‐functionalized poly(N‐isopropylacrylamide) (PNiPAM) microgel building blocks are shown to undergo an assemble–freeze–disassemble process. The microgel assemblies, which are controlled by monitoring the attractive and repulsive potentials between the soft colloidal particles, are then frozen by forming inter‐particle metal–terpyridine bis‐complexes upon addition of the metallic cation (such as FeII, CoII). By oxidation of the metal–terpyridine bis‐complex links, the aggregates open up, which is due to the complex dissociation releasing the connected particles in the form of single microgels. We extended our work to the development of 1D filaments and 2D membranes materials made of soft particles connected via supramolecular chemistry.
Fabrication of reinforced and toughened poly(lactic acid)/poly(butylene adipate‐co‐terephthalate) composites through solid die drawing process
Authors: Zhang Tongying , Wu Pingping , Yang Qi , Jiang Jian 
Published: February 2020

AbstractIn this study, poly(butylene adipate‐co‐terephthalate) (PBAT) was introduced to poly(lactic acid) (PLA) matrix to improve its inherent poor toughness. Besides, the orientation structure was also introduced via die drawing process to compensate for strength loss. The results indicate that die drawing process contributes to improve the mechanical properties of PLA. The tensile strength, modulus, and elongation at break of die‐drawn pure PLA increased by 76.6, 36.1, and 1,375.0%, respectively, compared with those of isotropic PLA. Moreover, the tensile strength can be further improved by the addition of PBAT. The die drawing process can remarkably improve crystallinity, and the orientation factor is high when the PBAT content is less than 30 wt%. By combining the PBAT with highly oriented structure imported by die drawing process, it is possible to prepare simultaneously reinforced and toughened materials, which provides a new insight into the modification of PLA.

Published: February 2020

AbstractThe aim of this study is to investigate the synergistic effects of modified TiO2/multifunctionalized graphene oxide nanosheets at different ratios on the interface compatibility between starch and poly(lactic acid) (PLA). To this end, silanylated nano‐TiO2 (MTiO2, 1 and 2%) and alkylated maleic anhydride grafted graphene oxide (f‐GO, 0.1, 0.2, and 0.4%) at different combinations are blended with the PLA‐starch composites using solution blending technique. Then, the synergistic effects of MTiO2 and f‐GO on PLA/starch matrix are investigated in terms of the morphology, crystallinity, structural characterization, thermal stability, dynamic mechanical, and antiaging properties, and the related mechanisms. The Raman and Fourier transform infrared spectroscopy spectra verify the successful synthesis of the two modified nanofillers (f‐GO and MTiO2) and the formation of strong hydrogen bond within the PLA‐starch nanocomposites. Due to the strong interfacial interaction and the synergistic effect from the combination of 1% MTiO2 and 0.2% f‐GO, obvious improvement was observed in PLA‐starch versus other nanocomposites in terms of morphology, thermal stability, surface hydrophobicity, storage modulus, ultraviolet‐shielding capacity, and aging‐resistance. Furthermore, differential scanning calorimeter (DSC), isothermal crystallization kinetic, and X‐ray diffraction analysis demonstrate that f‐GO and the M‐TiO2 significantly synergize in enhancing the crystallization rate and crystallinity of PLA/starch matrix. These results provide novel insights for constructing high‐performance nanocomposites and facilitate their applications in food packaging.

AbstractEine konsistente Kreislaufführung der zur Verfügung stehenden Ressourcen ist eine der großen Herausforderungen für das Bauen in der Zukunft. Dieser Aufsatz liefert einen Beitrag hinsichtlich der Diskussion und Weiterentwicklung der Recyclingfähigkeit im Bauwesen. Es wird ein Modell vorgestellt, das über die reine Betrachtung von Baustoffen hinausgeht und die Recyclingfähigkeit von bestehenden oder neu zu errichtenden Baukonstruktionen insgesamt beschreibt. Auf diese Weise rücken Aspekte der Fügung und Lösbarkeit der einzelnen Baustoffe sowie Errichtungs‐ und Rückbauprozesse in den Vordergrund. Bei der Entwicklung des Modells wurde darauf geachtet, dass seine Struktur kompatibel ist mit bestehenden Klassifizierungen und Kategorien und an bestehende Rahmenbedingungen und Methoden anknüpft. Das Modell bietet mittelfristig eine Grundlage für eine ganzheitliche Entwicklung und Diskussion der Kreislaufführung im Bauwesen und soll langfristig einen Beitrag zur Entwicklung eines Nachweisverfahrens zur Abbildung einer nachhaltigen Nutzung natürlicher Ressourcen liefern.

AbstractObjectiveExplore trauma, stress, and other predictive factors for treatment outcome in conversion disorder/functional neurological disorder (CD/FND).MethodsProspective observational design. Clinical cohort study among consecutive outpatients with DSM‐IV CD/FND in a specialized mental health institution for somatic symptom disorders and related disorders (SSRD), presented between 1 February 2010 and 31 December 2017. Patient files were assessed for early childhood trauma, childhood sexual abuse, current stress, and other predictive factors. Patient‐related routine outcome monitoring (PROM) data were evaluated for treatment outcome at physical (Patient Health Questionnaire [PHQ15], Physical Symptoms Questionnaire [PSQ]) level as primary outcome, and depression (Patient Health Questionnaire [PHQ9]), anxiety (General Anxiety Disorder [GAD7]), general functioning (Short Form 36 Health Survey [SF36]), and pain (Brief Pain Inventory [BPI]) as secondary outcome.ResultsA total of 64 outpatients were included in the study. 70.3% of the sample reported childhood trauma and 64.1% a recent life event. Mean scores of patients proceeding to treatment improved. Sexual abuse in childhood (F(1, 28) = 30.068,β = 0.608p < .001) was significantly associated with worse physical (PHQ15, PSQ) treatment outcome. 42.2% reported comorbid depression, and this was significantly associated with worse concomitant depressive (PHQ9) (F[1, 39] = 11.526,β = 0.478,p = .002) and anxiety (GAD7) (F[1,34] = 7.950,β = 0.435,p = .008) outcome.ConclusionChildhood sexual abuse is significantly associated with poor treatment outcome in CD/FND. Randomized clinical trials evaluating treatment models addressing childhood sexual abuse in CD are needed.

Published: February 2020

AbstractFeO‐doped TiO2 nanoparticle photocatalysts were immobilized onto the surface of fibrous activated carbon (ACF) via a sol‐gel process. As an adsorbent and photocatalyst, FeO‐TiO2 on immobilized ACFs (FeO‐TiO2/ACF) greatly improved the photocatalysis rate of hydrogen production as compared with pure TiO2 and ACF‐TiO2 under UV irradiation and visible light. The addition of ACFs surface significantly reduced the photogenerated pairs of electrons‐hole recombination, thereby promoting the photocatalysis action of doped photo‐metal oxides of FeO‐TiO2. Co‐doping of FeO onto the lattice of the TiO2 approach can improve the absorption activity of visible light through photo‐metal oxide of TiO2 and further enhance hydrogen production under visible light. The photocatalytic fabrics (FeO‐TiO2/ACF) were effortlessly split out from the experimental solution for re‐utilization and exhibited high stability even after five complete regeneration cycles.

Published: February 2020

AbstractNitridophosphates exhibit an intriguing structural diversity with different structural motifs, for example, chains, layers or frameworks. In this contribution the novel nitridophosphate Sr3P3N7 with unprecedented dreier double chains is presented. Crystalline powders were synthesized using the ammonothermal method, while single crystals were obtained by a high‐pressure multianvil technique. The crystal structure of Sr3P3N7 was solved and refined from single‐crystal X‐ray diffraction and confirmed by powder X‐ray methods. Sr3P3N7 crystallizes in monoclinic space group P2/c. Energy‐dispersive X‐ray and Fourier‐transformed infrared spectroscopy were conducted to confirm the chemical composition, as well as the absence of NHx functionality. The optical band gap was estimated to be 4.4 eV using diffuse reflectance UV/Vis spectroscopy. Upon doping with Eu2+, Sr3P3N7 shows a broad deep‐red to infrared emission (λem=681 nm, fwhm≈3402 cm−1) with an internal quantum efficiency of 42 %.

AbstractDie elektrischen Eigenschaften von Partikeln insbesondere der Durchgangswiderstand von Partikelschüttungen haben in vielen verfahrenstechnischen Prozessen, bei der Produktqualifizierung oder dem Brand‐ und Explosionsschutz eine entscheidende Bedeutung. Da sich der Ladungstransport in einem dispersen System von dem in einem homogenen Festkörper unterscheidet, ist der Durchgangswiderstand entscheidend von den Produkteigenschaften der Partikel und des Fluids abhängig. Im Rahmen dieser Arbeit wurde die Abhängigkeit des Durchgangswiderstandes von der inneren Struktur der Schüttung, der relativen Feuchtigkeit, der Konditionierungszeit bei unterschiedlichem Klima und der mittleren Partikelgröße in einer konzentrischen Messzelle untersucht.
Investigating seasonal color change in the environment by color analysis and information visualization
Authors: Yang Muhe 
Published: February 2020

AbstractColor, as one of the most important dimensions of vision, plays a key role in place identity and people's experience in the environment. This study aims to investigate people's visual experience of seasonal color change in the environment, and proposes an approach for analyzing and communicating environmental colors by combining color analysis and information visualization. Employing crowdsourced Flickr photos, the approach is tested in four gardens: the Humble Administrator's Garden, Ryoanji, the Garden of Versailles, and Central Park in New York. The results show direct comparisons of seasonal color change patterns in different environments, and reflect characteristics of the environments as well as people's experience of color during the four seasons. The primary contribution of this study is to provide a way of communicating colors in landscape design and color research.
Experience and future perspectives on the use of the Papanicolaou Society of Cytopathology Terminology System for reporting pancreaticobiliary cytology
Authors: Saieg Mauro , Pitman Martha B. 
Published: February 2020

AbstractThe Papanicolaou Society of Cytopathology developed a set of guidelines for reporting pancreaticobiliary cytology in 2014 (PB System), with a six‐tiered system: Nondiagnostic, Negative, Atypical, Neoplastic (Benign or Other), Suspicious, and Positive. This proposed scheme incorporates ancillary testing such as biochemical testing of cyst fluids for diagnosis and provides terminology that standardizes the category of the various diseases of the pancreas, some of which are difficult to diagnose specifically by cytology alone. Since its initial publication five and half years ago, several groups have published their experiences on the use of the PB System and have shown that most objectives proposed by the original publication have been achieved. They have shown that there is a better understanding and definition of the diagnostic categories with an associated distribution and risk of malignancy. The diagnostic categories of Neoplastic: Other, Suspicious, and Malignant show a high sensitivity and specificity for the diagnosis of malignancy. The System also provides a multi‐specialist view of pancreatic lesions, with biochemical and radiological findings being incorporated into the final pathological report. The present review summarizes these findings and discusses the future perspectives and foreseen changes that are to be incorporated to a second edition of the reporting System.
