Published: February 2021

Functionalized gold nanostructures with efficient, broadband absorption properties are of interest for a variety of biomedical applications. In this study, we report a plasmon-enhanced functionalization methodology that results in selective surface conjugation of a fluorescent probe via two-photon excitation under visible-wavelength laser irradiation. The fluorescent probe was designed to incorporate a thiolated 4-piperidinyl-1,8-naphthalimide (SNaph) entity, carrying a photolabile 6-nitroveratryl (NV) protecting group, straightforwardly synthesized in a few steps in good yield. Efficient plasmon-enhanced photodeprotection of the NV-group, followed by thiol-gold bond formation on gold nanoisland substrates was recorded upon exposure to 650 nm laser light, supported by confocal laser scanning microscopy (CLSM). Photolysis of the labile NV-group, thereby efficiently exposing the free mercapto group of the thiolated 1,8-naphthalimide, was recorded upon UV-irradiation at 350 nm, whereas no cleavage occurred at 650 nm. No conjugation occurred on featureless, gold-plated flat substrates under the same conditions. Surface plasmon-enhanced two-photon excitation at plasmonic hotspots in the absorber layer thus resulted in selective and efficient conjugation of the fluorescent probe to the structured surfaces. The resulting laser-assisted approach introduces the advantage of accomplishing selective molecular functionalization at plasmonic hotspots, owing to the combined, simultaneous effects of long-wavelength deprotection and spontaneous conjugation.
Geometrical Reorganization of a Methane Cation upon a Sudden Ionization: An Isotope Effect in Electronic Non Equilibrium Quantum Dynamics
Authors: Gonçalves Cayo , Levine Raphael D. , Remacle Francoise
Published: February 2021

An ultrafast structural, Jahn-Teller (JT) driven, electronic coherence mediated quantum dynamics in the CH4+ and CD4+ cations that follows a sudden ionization by an XUV attopulse, exhibits a strong isotope effect. The JT effect makes the methane cation unstable in the Td geometry of the neutral. Upon the sudden ionization the cation is produced in a coherent superposition of three electronic states that are strongly coupled. On the ground state of the cation the few femtosecond structural rearrangement leads first to a geometrically less distorted D2d minimum followed by a reorganization to a shallow C2v minimum. The dynamics is computed for an ensemble of 8000 ions randomly oriented with respect to the polarization of the XUV pulse. The ratio, about 3, of the CD4+ and CH4+ autocorrelation functions, is in agreement with experimental measurements of the high harmonic spectra. The high value of the ratio is attributed to the faster electronic coherence dynamics in CH4+.
Wildfire-Derived Pyrogenic Carbon Modulates Organic Matter and Microbial Functioning in a Fluvial Ecosystem

Published: February 2021

Wildfires produce large amounts of pyrogenic carbon (PyC), including particulate charcoal, known for its chemical recalcitrance and sorption affinity for organic molecules. Wildfire-derived PyC is highly mobile in the landscape and can be transported to fluvial networks where it may impact natural dissolved organic matter (DOM) and microbial biofilms. The effects of PyC on freshwater ecosystems and carbon cycling therein remain poorly investigated. To address this research gap, we used in-stream flumes with a control vs treatment design (pulse addition of PyC particles). We present evidence that field-aged PyC inputs into river ecosystems can alter dissolved organic carbon (DOC) concentration, DOM composition, pH, and enzymatic activities in benthic biofilms. In stream DOM composition was altered due to leaching of pyrogenic DOM from PyC and possible concurrent sorption of riverine DOM to PyC. DOM changes and increase in pH were associated with changes in enzymatic activities, which reflected preferential usageof recalcitrant over easily available DOM by biofilms. Furthermore, we observed particulate PyC sedimentation on biofilm surfaces, which may further modulate the impacts of PyC. This study highlights the importance of PyC for in-stream DOM propertiesand biofilm functioning with implications for in-stream biogeochemical cycling in fire affected watersheds.
A Phage-Compatible Strategy to Access Macrocyclic Peptides Featuring Asymmetric Molecular Scaffolds as Cyclization Units
Authors: Oppewal Titia Rixt , Hekelaar Johan , Mayer Clemens
Published: February 2021

The cyclization of peptides appended onto proteins or whole bacteriophages is typically achieved via disulfide formation, the use of symmetric crosslinkers or the incorporation of noncanonical amino acids. Unfortunately, neither of these strategies is amenable toward generating libraries for the selection of macrocyclic peptides (MPs) akin to those found in nature, which often feature asymmetric molecular scaffolds as cyclization units that improve binding to their targets. To meet this challenge, we present an efficient two-step strategy to access MPs via the programmed modification of a unique cysteine residue and an N-terminal amine. We demonstrate that this approach yields MPs featuring asymmetric cyclization units from both synthetic peptides and when linear precursors are appended onto a phage-coat protein. Given that the employed conditions are compatible with phage display protocols, our work paves the way for the selection of natural-product-like MPs from randomized peptide sequences by phage display.

Published: February 2021

Increased body mass index (BMI) is considered a significant factor in several malignancies of body. It also affects the prognosis of the management of malignancies. Its role in cancer of the oral cavity should also be evaluated as another risk factor other than tobacco, alcohol, virus etc. Therefore this study was conducted to evaluate the correlation between BMI and cancer of the oral cavity.   A total of 160 patients (140 males, 20 females) with confirmed histopathologic diagnosis of oral squamous cell carcinoma (OSCC) and 200 healthy controls were enrolled. Height and weight of each study subject were measured. BMI was calculated by dividing the weight of the subject in kilograms with the square of the height in the square of metres. Chi-square test was used for evaluation of the level of significance.  The number of those subjects with OSCC belonging to the overweight and obese group was 136 while the number of those healthy controls belonging to the overweight and obese group was 24. The statistical analysis revealed a significant correlation between BMI and oral cancer. There is a significant correlation between oral cancer and increased BMI. Increased BMI can also be considered as another critical risk factor for oral cancer because it has been found associated with other cancers of the oral cavity.

Published: February 2021

© 2019 CSIRO. The number of New Zealand's freshwater fish listed as threatened has increased since 1992 when the first New Zealand threat classification system list was compiled. In this study, temporal and land cover-related trends were analysed for data on freshwater fish distribution, comprising more than 20 000 records for the 47 years from January 1970 to January 2017 from the New Zealand Freshwater Fish Database. The analysis included individual species abundance and distribution trends, as well as an index of fish community integrity, namely the Index of Biotic Integrity (IBI). Of the 25 fish species that met the requirements for analysis to determine changes in the proportion of sites they occupied over time, 76% had negative trends (indicating declining occurrence). Of the 20 native species analysed for the proportion of sites occupied over time, 75% had negative trends; 65% of these were significant declines and more species were in decline at pasture sites than natural cover sites. The average IBI score also declined over the time period and, when analysed separately, the major land cover types revealed that the IBI declined at pasture catchment sites but not at sites with natural vegetation catchments.

Railway Sidings as an Important Part of the Railway Freight Transport Competitiveness as Well as the Realization of the Sustainable Transport Development Policy in Poland
Authors: Drewnowski Arkadiusz
Published: February 2021

The railway sidings handled by the freight transport are primordial operating points in relation to the freight transport as a whole. Every active railway siding constitutes a natural source for creation of a flow of loaded wagons where, in consequence, the transport becomes more frequent on the railway network and rare on the car one. The handled railway sidings influence the realization of the principles of the sustainable transport development policy. The number of the operated railway sidings measure, at the same time, the competitiveness of this transport branch in the Polish transportation system.

In the article, the legal regulations, the current situation as well as the issues in relation to the functioning of the railway sidings in Poland are exposed. The propositions to make the railway sidings participate actively in Polish railway freight transport are also listed. They are particularly significant for the national transportation system.

The influence of diaphragm stiffening on welded tubular nodes in arch bridges
Authors: Stael Dries , De Backer Hans , Van Bogaert Philippe
Published: February 2021

A tubular arch bridge is prone to fatigue damage, particularly in the presence of varying traffic loads. The intersection of various tubes at the nodes of a tubular structure constitutes a radical transition of the geometry of the main tube. Due to geometric discontinuity, stress concentrations are introduced at the nodes. Because the nodes are welded, other stress concentrations add up to the former ones, particularly near the weld toe of the joints. By introducing internal diaphragms inside the main tube, the stresses in the weld toe can be reduced. This paper focuses on decreasing the hot spot stresses at the weld toe, as a function of the diaphragm location. By lowering the stresses at the weld toe, the fatigue resistance of the tubular arch bridge will be increased. To calculate these so- called hot spot stresses, accurate FE-models are being be assembled.

Authors: Rubio María Emilia Vidargas , Herrera Dra. Iliana , Bartolo Dra. Abigail Valdez , Roldan Dra. Ivette Buendia
Published: February 2021

Background:  Telomeres are DNA sequences that can be found at the ends of chromosomes, and prevent them from being damaged, they show shortening every time with the cell division, and when it is below a minimal length, the cells interrupt their cell cycle. Cigarette smoke contains chemical compounds that contribute to the oxidative damage in cells.

Method: subjects over 65 years old belonging to the INER ageing cohort, residents of Mexico City and asymptomatic respiratory patients were studied. A questionary was applied on demographic characteristics, smoking habits (active and passive), and the study groups were identified as active smoking (AS), passive smoking (PS) and non-exposed subjects (NE). Telomere length was measured in a serum sample using the quantitative method based on RT-PCR.

Results: We compared clinical data and telomere length of 333 subjects, showing that non-exposed group are below the 10th percentile, with the smallest telomere size (NE 1.38 + 0.36 vs PS 1.50 + 0.40 and AS 1.41 +0.43).

Conclusion: There is no evidence that telomere shortening have increased as a result of active or passive smoking. It is suggested that smoking is not the only one responsible for the presence of shorter telomeres.

Published: February 2021

Lahan gambut di lokasi penelitian yang digunakan untuk perkebunan sawit berdampingan dengan tanah mineral berbahan induk ultrabasa berkadar Mg tinggi. Tanah berkadar Mg tinggi dapat mengakibatkan terhambatnya pertumbuhan tanaman dan gangguan serapan hara. Penelitian ini bertujuan mempelajari distribusi beberapa sifat kimia tanah seperti pH; kandungan unsur kalium (K), kalsium (Ca), magnesium (Mg), natrium (Na) dapat ditukar; besi (Fe), mangan (Mn), tembaga (Cu), seng (Zn) total dan terekstrak DTPA dalam gambut dan hubungannya dengan kedalaman lapisan gambut dan jarak terhadap tanah mineral berbahan induk batuan ultrabasa. Contoh gambut sekitar 1,0 kg diambil secara komposit dari setiap kedalaman gambut 0 – 30, 30 – 60 dan 60 – 90 cm pada transek toposekuen dari setiap jarak 100, 200, 300, 400, 500 dan 600 m dari perbatasan tanah mineral ultrabasa. Analisis contoh gambut dilakukan untuk menetapkan (i) kapasitas tukar kation (KTK) dan pH H2O 1:5; (ii) kandungan hara makro K, Ca, Mg dan benefisial Na menggunakan amonium asetat 1 N pH 7; dan (iii) kandungan total unsur mikro Fe, Cu, Zn, Mn serta kandungan unsur-unsur tersebut dengan pengekstrak DTPA. Hasil penelitian menunjukkan nilai pH gambut menurun sangat nyata berdasarkan kedalaman lapisan gambut dan cenderung menurun dengan semakin jauh dari tanah mineral. Nilai KTK berfluktuasi dan cenderung meningkat sesuai peningkatan kedalaman lapisan gambut dan jarak dari tanah mineral. Berdasarkan hasil pengukuran Mg dan Fe, hara yang berasal dari tanah mineral mempengaruhi gambut hingga jarak 600 m dari batas gambut. Tanah gambut mengandung Mg, Na, Fe, Mn, dan Zn tersedia dalam kadar tinggi dan K and Ca tersedia dalam kadar rendah. Hara Cu tersedia tergolong cukup pada semua kedalaman dan jarak  kecuali kedalaman 60 – 90 cm dan jarak 600 meter. Kandungan hara benefisial Na menunjukkan korelasi positif dengan kedalaman lapisan gambut yang mengindikasikan pengaruh marin pada tanah mineral bawah gambut. Disparitas yang besar antara Mg dengan kation lain dapat mengganggu penyerapan hara oleh akar tanaman dan memungkinkan pencucian K dan Ca keluar dari solum.

Reception of Bicultural Identity in Arabic Diaspora Literature: The Works of Elia Abu Madi in Qisshat Al-Adabi Al-Mahjary
Authors: Manshur Fadlil Munawwar
Published: February 2021

Literature by the Arab diaspora in the United States has promoted dialectical interpretations of authors' cultural identities, balancing their ancestral cultural identities with those of their new country. In regards to the bicultural identity found in the Arabic-language poetry of Elia Abu Madi, it can be seen that the poet produced several discourses portraying a bicultural reality. The historical essence of Arabic diaspora literature is found not only in its social expressions and representations, but also in the interactions of Arabic and American culture that have produced a bicultural identity. It consists of five key concepts: sign analysis, which functions to reveal the meaning of signs or symbols in the material object; interpreter analysis, which functions to discover the correlations between authors' intents and readers' horizons of expectation; effect analysis, which functions to reveal the influence of literary works on their readers; reference analysis, which functions to reveal authors' repertoires; and context or conditions analysis, which functions to reveal the bicultural identity of authors. This research concludes that, in the author's bicultural identity, the United States is positioned as a prosperous country of dynamic multiculturalism, where people are passionate in their work and art. Meanwhile, Lebanon is positioned as a country where people live mechanically, facing hardship and minimal productivity owing to their lack of security. Conversely, although the United States is prosperous and safe, owing to its orientation towards religious pluralism, its people are more positivistic and material in their lives. They thus tend to ignore spiritual aspects.

Kurikulum tidak akan berarti tanpa diimplementasikan dalam proses pembelajaran; sebaliknya pembelajaran tidak akan efektif tanpa didasarkan pada kurikulum sebagai pedoman. Tujuan evaluasi pembelajaran adalah untuk menghimpun informasi yang dijadikan dasar untuk mengetahui taraf kemajuan, perkembangan, dan pencapaian belajar siswa, serta keefektifan pengajaran guru. Evaluasi pembelajaran kurikulum 2013 dilakukan sebelum pembelajaran (pre test) dan sesudah pembelajaran (post test) . Penerapan Kurikulun 2013 ditujukan agar guru memperoleh ruang yang lebih leluasa untuk mengembangkan potensi siswa secara seimbang dalam tiga aspek, yaitu aspek kognitif, psikomotorik dan afektif. Kurikulum ini harus dikawal dengan kebijakan yang sinergis.
