Unimolecular, bimolecular and intramolecular hydrolysis mechanisms of 4-nitrophenyl β-D-glucopyranoside
Authors: Alhifthi Amani , Williams Spencer
Published: June 2021

1,2-trans-Glycosides hydrolyze through different mechanisms at different pH values, but systematic studies are lacking. Here we report the pH-rate constant profile for the hydrolysis of 4-nitrophenyl β-D-glucoside. An inverse kinetic isotope effect of k(H3O+)/k(D3O)+ = 0.65 in the acidic region indicates that the mechanism requires the formation of the conjugate acid of the substrate for the reaction to proceed, with heterolytic cleavage of the glycosidic C-O bond. Reactions in the pH-independent region exhibit general catalysis with a single proton in flight, a normal solvent isotope effect of kH/kD = 1.5, and when extrapolated to zero buffer concentration show a small solvent isotope effect k(H2O)/k(D2O) = 1.1, consistent with water attack through a dissociative mechanism. In the basic region, solvolysis in 18O-labelled water and H2O/MeOH mixtures allowed detection of bimolecular hydrolysis and neighboring group participation, with a minor contribution of nucleophilic aromatic substitution. Under mildly basic conditions, a bimolecular concerted mechanism is implicated through an inverse solvent isotope effect of k(HO–)/k(DO–) = 0.5 and a strongly negative entropy of activation (DS‡ = –13.6 cal mol–1 K–1). Finally, at high pH, an inverse solvent isotope effect of k(HO–)/k(DO–) = 0.6 indicates that the formation of 1,2-anhydrosugar is the rate determining step.

Published: June 2021

Well-ordered spin arrays are highly desirable for next-generation molecule-based magnetic devices, and yet its synthetic method remains a challenging task. Herein, we demonstrate the realization of two-dimensional supramolecular spin arrays on surfaces via halogen-bonding molecular self-assembly. A bromine-terminal perchlorotriphenymethyl radical with net carbon spin was synthesized and deposited on Au(111) to achieve two-dimensional supramolecular spin arrays. By taking advantage of the diversity of halogen bonds, five supramolecular spin arrays are presented with ultrahigh spin densities (up to the value of 3 × 1013 spins at the size of a flash drive), as probed by low-temperature scanning tunneling microscopy at the single-molecule level. First principle calculations verify that the formation of three distinct types of halogen bonds can be used to tailor supramolecular phases via molecular coverage and annealing temperature. Our work demonstrates supramolecular self-assembly as a promising method to engineering 2D spin arrays for potential application in magnetic devices.
A General Approach to 2,2-Disubstituted Indoxyls: Total Synthesis of Brevianamide A and Trigonoliimine C
Authors: Xu Fan , Smith Myles
Published: June 2021

The indoxyl unit is a common structural motif in alkaloid natural products and bioactive compounds. Here, we report a general method that transforms readily available 2-substituted indoles into 2,2-disubstituted indoxyls via nucleophile coupling with a 2-alkoxyindoxyl intermediate and showcase its utility in short total syntheses of the alkaloids brevianamide A (7 steps) and trigonoliimine C (6 steps). The developed method is operationally simple and demonstrates broad scope in terms of nucleophile identity and indole substitution, tolerating 2-alkyl substituents and free indole N–H groups, elements beyond the scope of most prior approaches. Spirocyclic indoxyl products are also accessible via intramolecular nucleophilic trapping.

Published: June 2021

DNA overwinding and underwinding between adjacent Holliday junctions have been applied in DNA origami constructs to design both left-handed and right-handed nanostructures. For a variety of DNA tubes assembled from small tiles, only an abstract concept of the intrinsic tile curvature was previously used to explain their formation. Details regarding the quantitative and structural descriptions of the intrinsic tile curvature and its evolution in DNA tubes by coupling with arm twists have been lacking. In this work, we designed three types of tile cores from a circular 128 nucleotide scaffold by longitudinal weaving (LW), bridging longitudinal weaving (bLW), and transverse weaving (TW) and assembled their 2D planar or tubular nanostructures via inter-tile arms with a distance of an odd or even number of DNA half-turns. The biotin/streptavidin (SA) labeling technique was applied to define the tube configuration with addressable inside and outside surfaces and thus their component tile conformation with addressable concave and convex curvatures. Both chiral tubes possessing left-handed and right-handed curvatures could be generated by finely tuning p and q in bLW-Ep/q designs (bLW tile cores joined together by inter-tile arms of even number of half-turns with the arm length of p base pairs (bp) and the sticky end length of q nucleotides (nt)). We were able to assign the chiral indices (n,m) to each specific tube from the high-resolution AFM images, and thus estimated the tile curvature angle with a regular polygon model that approximates each tube’s transverse section. We attribute the curvature evolution of bLW-Ep/q tubes composed of the same tile core to the coupling of the intrinsic tile curvature and different arm twists. A better understanding of integrated actions of different types of twisting forces on DNA tubes will be much more helpful in engineering DNA nanostructures in the future.

Published: June 2021

Invariant natural killer T (iNKT) cells are a conserved population of innate T lymphocytes that interact with key antigen-presenting cells to modulate adaptive T-cell responses in ways that can either promote protective immunity, or limit pathological immune activation. Understanding the immunological networks engaged by iNKT cells to mediate these opposing functions is a key pre-requisite to effectively using iNKT cells for therapeutic applications. Using a human umbilical cord blood xenotransplantation model, we show here that co-transplanted allogeneic CD4+iNKT cells interact with monocytes and T cells in the graft to coordinate pro-hematopoietic and immunoregulatory pathways. The nexus of iNKT cells, monocytes, and cord blood T cells led to the release of cytokines (IL-3, GM-CSF) that enhance hematopoietic stem and progenitor cell activity, and concurrently induced PGE2-mediated suppression of T-cell inflammatory responses that limit hematopoietic stem and progenitor cell engraftment. This resulted in successful long-term hematopoietic engraftment without pretransplant conditioning, including multi-lineage human chimerism and colonization of the spleen by antibody-producing human B cells. These results highlight the potential for using iNKT cellular immunotherapy to improve rates of hematopoietic engraftment independently of pretransplant conditioning.

Published: June 2021

The perceptual strength in learning styles refers to obtain knowledge most easily by different sensory systems. Discovering the perceptive strengths and weaknesses of each student and finding ways to optimize their learning is always a challenge for the professor. In extreme cases such as in the visual impairment touch-and-go approaches can be an alternative. This paper aims at sharing the usage of tactual resources as a learning strategy in a case of visual impairment, developed by a group of professors for supporting classes of Linear Algebra and Analytic Geometry at Sorocaba Engineering College (Faculdade de Engenharia de Sorocaba - FACENS). As a result, there was ease of handling tactile resources by the student, considerable gain in understanding the theoretical subjects and of practical cases analyzed in classroom. According to professors’ perception, the concrete experimentation by using the touch-and-go strategy provided satisfactory support for the classes. Therefore, the usage of touch-and-go by means of the tactile resources can be considered as a promising approach as a learning strategy in cases of visual impairment.

The Review of the Welding Robot’s Precision
Authors: Li Chengqiang
Published: June 2021

Welding is an significant link in industrial production, and it is known as the "industrial tailor". However, welding fume, arc light, and metal spatter cause a harsh welding working environment, and the quality of welding has a decisive influence on product quality. Low production capacity, difficult recruitment, and low profits have become drawbacks for the development of the welding field. Combining traditional welding with robots can solve these drawbacks and increase the precision of welding. Welding robots are industrial robots engaged in welding and are mostly used in large-scale manufacturing fields such as automobile manufacturing. Welding robots are divided into spot welding robots, arc welding robots and laser welding robots. In addition, body accuracy and control accuracy are the two main factors that affect the robot welding accuracy. In this case, the sensing technology of welding robot is also essential.

Objective: To explore the effect of propofol (Prof) on the proliferation, migration and invasion of human gastric cancer cell MGC-803 and its molecular mechanism. Methods: The MTT method was used to study the effects of Prof with different doses and durations on the viability of MGC-803 cells. Hoechst 33258 staining and electron microscopy were used to detect the effects of Prof on MGC-803 cell apoptosis. Transwell experiments were used to detect the effects of Prof on the migration and invasion of MGC-803 cells. RT-PCR detects the effect of Prof on the expression of miR-195 in MGC-803 cells, and Western Blot detects the effect of Prof on the protein expression of JAK/STAT signaling pathway. Results: Compared with 0mg/ml Prof, 5mg/ml, 10mg/ml and 20mg/ml Prof treatment with 24h, 48h and 72h can significantly reduce cell viability (P <0.05). Compared with the Control group, the percentage of Hoechst 33258 staining positive cells in the Prof group and the apoptosis rate under the electron microscope were significantly increased (P <0.05). Compared with the Control group, the cell migration rate and invasion rate of the Prof group were significantly reduced (P <0.05). Compared with the Control group, the expression of miRNA-195 in the Prof group cells was increased significantly (P <0.05). Compared with the Control group, the activity of p-Jak1 and p-STAT3 proteins in the Prof group were significantly reduced (P <0.05). Conclusion: Prof can reduce the cell viability, migration and invasion of gastric cancer cell MGC-803, and promote its apoptosis. Its mechanism may be related to the promotion of miR-195 expression and inhibition of JAK/STAT signal pathway activity.

Research on the Pricing of Convertible bonds in China---Migration risk based on credit rating
Authors: Heng Zhang , Zhao Yuyang , An Qiguang
Published: June 2021

At present, further research and exploration on credit risks are being carried out in the global field, and increasingly profound modern credit risks are exposed to the bond market. This requires that we cannot ignore the impact of credit rating migration risk on bond pricing, so as to adapt to the sustainable and healthy development of the bond market under the new normal of China's economy. The innovation point of this paper is to try to analyze the pricing of Convertible bonds in China from the perspective of credit rating migration risk. Tsiveriotis and Fernandes(1998) model is selected, and the credit risk in the model is assumed to be caused by the credit rating migration risk, and the credit spread is used to measure the credit rating migration risk. The research conclusion of this paper is as follows: First, it is valid to consider the risk of credit rating migration in the TF(1998) model. The market price of convertible bonds is on average 1.22% higher than the theoretical value of the model. In general, the theoretical value obtained from the model has little deviation from the market price, and has a good fitting degree. Second, from the Angle of credit rating, the selection of 32 samples of convertible bonds only empirical research shows that the credit rating of AA - convertible bonds average deviation rate is negative, suggest that the credit rating of AA - the phenomenon of convertible bonds value is underestimated, and AAA credit rating to AA, AA +, the average deviation rate of convertible bonds is positive, that credit rating AA (containing AA) more convertible bond value is overrated phenomenon, and the higher the credit rating of the average deviation rate of convertible bond, the greater the overvalued levels. It has certain guiding significance for participants in the convertible bond market.

The Knowledge Landscape of School Disciplinary Committees on Disciplinary Policies in Mopani Education district, Limpopo Province, South Africa
Authors: Mathebula Rifumuni Nancy , Runhare Tawanda
Published: June 2021

Despite the clarity of the South African Schools Act (SASA) 84 of 1996 on the need to craft and implement a learners’ Code of Conduct by school governing bodies (SGBs), there seems to be a gap between the espoused learner disciplinary policies and practice at schools. Using the case study research design, the knowledge scope on education policies by the school disciplinary committees (SDCs) was examined at two secondary schools in a predominantly rural South African district. The study employed a qualitative approach to gather data from purposefully selected informants using focus group and face-to-face interviews. The study sample was composed of 35 participants who were school disciplinary policy duty bearers, comprising 10 SGBs, 10 school management teams (SMTs) and 10 SDC members, as well as five class teachers. The main findings from the thematically analysed narrative data pointed to inadequate knowledge of policies by most SDC committee members. In addition, although the two schools had learners’ codes of conduct that were aligned to SASA, the SDCs were loosely adhering to the provisions of the disciplinary policies in their operations. The gap between the espoused policy and policy in action was found to be due to the policy duty bearers’ inadequate knowledge of the national policy that governs school discipline. This calls for the Department of Basic Education (DBE) to offer policy enhancement workshops for SDCs and to employ a policy monitoring instrument on the functioning of SCDs.

In the study, a copper thermosiphon with a length of 1 m, diameter of 14 mm and wall thickness of 1 mm was used. Experiments were performed with both pure water and nano fluid to be make a comparison. To observe the performance of system in different operating conditions, the experiments were carried out at 3 different heating power (150, 300, 450 W) and 3 different coolant flow rates (3, 6, 9 g/s). In all experimental conditions, Fe + Pure water nanofluid had better results than pure water. The highest efficiency value was found to be 77.9% in the experiment using Fe + Pure water nano fluid, performed at 150 W power and 9 g/s water flow rate. When pure water was used in this experiment, the efficiency value was obtained as 67.7% and the improvement rate was 15%. The highest improvement rate was obtained as 50.3% in the experiment conducted at 450 W heating power and 3 g/s coolant flow rate. The use of nano fluid has also reduced the thermal resistance of the thermosiphon. The highest rate of decrease in thermal resistances was obtained as 56.7% in the experiment performed at 150 W heating power and 3 g/s coolant flow rate.

Son yıllarda koyun ve keçi yetiştiriciliğine olan talebin artışı, bu üretim dalında ekonomik gelir kaynaklarını en iyi şekilde kullanma isteğine neden olmuştur. Asıl mesleği hayvancılık olmadığı halde bu üretim dalında başarılı olan birçok işletme sahibinin, koruyucu hekimlik adına doğru adımlar atma eğiliminde olduğu gözlenmiştir. Bu eğilimlerin başında elbette ki düzenli aşılamalar ve güncel bilgi paylaşımları gelmektedir. Teknoloji geliştikçe ülkemizde koyun ve keçilerde gözlenen başlıca hastalıklara karşı (keçi ciğer ağrısı, şap, enterotoksemi, veba, pnömoni gibi) uygulanan aşılar hakkında her gün yeni bilgilere ulaşılmaktadır. Aşı etkinliğinin en üst seviyede olması için; aşının içeriği, türü, hangi hastalıklarda kullanıldığı, saklama koşulları gibi konular giderek daha fazla önem kazanmıştır. Bu çalışmada, Türkiye’de koyun-keçilerde görülen bazı yaygın hastalıklar ile bunlara karşı uygulanan aşılar hakkında bilgiler özetlenmiştir. Son olarak da konuyla ilgili bazı teknik önerilere yer verilmiştir.

Calidad de vida I que dirige Guillermo Velázquez se torna un aporte imprescindible para los estudios históricos y sociales de la desigualdad en Argentina vistos desde una perspectiva interdisciplinaria amplia al considerar múltiples factores como salud, educación, poder adquisitivo, entre otros. No obstante, el trabajo puede contribuir también a estudios comparativos de significativa importancia para la región. Naturalmente, el extenso periodo histórico que abarca desde 1789 hasta comienzos del siglo XXI lo convierte en un aporte fundamental para todas las disciplinas sociales, desde la historia, la economía y la sociología hasta la geografía y la antropología.
“La Santa causa de la Antilla hermosa encuentra en Chile un entusiasmo ardiente”: El movimiento de solidaridad hacia el independentismo cubano durante 1895
Authors: Vega Henríquez Mario
Published: June 2021

El presente trabajo aborda la recepción de la guerra de independencia cubana de 1895 en Chile, a partir de la estrategia del Partido Revolucionario Cubano (PRC) de implementar vínculos de activa solidaridad hacia su causa mediante la visita de delegados a diversos países de la región, con la intención de presionar a sus respectivos gobiernos para lograr el reconocimiento de la condición de beligerantes de los insurgentes. Tal fue el caso de la presencia de Arístides Agüero en Chile quien durante 1895 fue recibido por diversas organizaciones populares que adhirieron a su causa tensionando la posición de neutralidad que el gobierno de Jorge Montt había definido, así como la posición vigilante de la influyente colonia española presente en el país. Lo anterior será analizado a partir del examen de prensa de la época, interpretando las representaciones discursivas construidas sobre este conflicto, con especial hincapié en los argumentos esgrimidos tanto por los partidarios como por los detractores del proceso de emancipación en las Antillas Mayores.

The Pseudo-Bonaventuran Meditationes vitae Christi is one of the most influential devotional narratives of the late middle ages. It was written in Tuscany in the early fourteenth century and survived in several Latin and vernacular manuscripts and early prints. An extensive discussion has engaged the scholars, especially about the issue of the first linguistic version of the text. Even if the Latin version seems to be the original text, the vernacular manuscript Paris, BnF, it. 115 stays as one of the most important and interesting witnesses of the work. One of the earliest surviving codices, it conserves the first Italian translation (penned in the Pisan area) of the text, enriched by a wonderful set of illustration. The present volume, which is the outcome of an international and interdisciplinary collaboration, offers the first critical edition of the text, the reproduction of all images, the edition of the instructions given to the artist, accompanied by detailed philological and art-historical commentaries, glossaries, and seven interdisciplinary introductory essays.
