Authors: Deenadayalan Sathish Kumar , Veeraiah Surendran , Elangovan Vidhubala , Sathyamurthi K.
Published: July 2022

Objectives:

Advanced cancer patients attending tertiary cancer centres from rural places are referred back to local physicians for symptom management. Due to lack of networking with palliative care centres (PCCs), the referred patients do not receive appropriate palliative care (PC) services. Hence, an attempt was made to map the PCCs in Tamil Nadu to make the referral system efficient.

Material and Methods:

PCCs in Tamil Nadu were identified from the National Health Mission directory, online sources and from morphine license annexure of drug control department. The details regarding nature of facility, PC model, service type, procedures, cost, morphine availability and type of personnel involved in their PCCs were collected from government and private centres. The data were analysed using descriptive statistics and geomapping of all the centres identified was created.

Results:

A total of 371 PCCs were identified, of which 32 were government headquarter hospitals (GHQH), 281 were government community centres and 58 were private. Eighty-three of the 90 centres (including GHQH and private) were active and 60 responded to the survey. More than half of the centres were hospital-based (61.7%) and 28.3% were community-based. The majority of the PCCs had in-patient (75%) and out-patient (63.3%) facilities and 63.3% had regular home visits. Forty-six centres provide PC service free of cost. Nearly 80% provide morphine for pain management, wherein 41 have obtained a license. In total, ten centres had a social worker and four had a psychologist.

Conclusion:

The number of PCCs is disproportionate, in which majority of the centres are clustered in urban areas. Integrating PC services into the existing health system is the way forward.

Published: July 2022

Background:

Angiolipomas are benign mesenchymal tumors comprising mature adipocytes and abnormal blood vessels, commonly found in the subcutaneous tissue of the trunk and rarely in the skull. Furthermore, sporadic cases of angiolipoma with arteriovenous fistula (AVF) have been reported.

Case Description:

We reported the case of a 72-year-old woman who presented with head swelling, seizures, and cognitive dysfunction. Computed tomography and magnetic resonance imaging revealed a right frontal bone tumor exceeding a sagittal suture of up to 10.7 cm. Angiography revealed AVF and varices formation. Endovascular embolization was performed to treat the AVF and reduce blood loss during surgical resection. Two days after the embolization, a craniotomy was performed; however, uncontrollable bleeding was observed at the time of tumor resection. Postoperatively, the patient was symptom-free and has been stable for 2 years without recurrence.

Conclusion:

Despite careful preoperative evaluation and treatment planning, the patient in this case report was difficult to treat. Such cases require adequate preparation.
Is there a limited value of cytoreductive surgery in elderly patients with malignant gliomas?
Authors: Elserius Anne S. L. , Hodson James , Zisakis Athanasios , Ughratdar Ismail
Published: July 2022

Background:

Glioblastoma (GB) is well known for being the most aggressive primary cerebral malignancy. The peak incidence is at 60–70 years of age, with over half of patients aged over 65 years at diagnosis.

Methods:

Patients with a confirmed histological diagnosis of GB between January 2009 and June 2016 at a single center were retrospectively identified. The inclusion criteria for the study were age over 65 years at diagnosis, and surgical management with either a burr hole biopsy or craniotomy.

Results:

A total of n = 289 patients underwent surgery for GB, with a median age at diagnosis of 71 years, and of whom 64% were male. Craniotomies were performed in 71%, with burr hole biopsies performed in the remainder (29%). Patient survival differed significantly with treatment modality (P < 0.001), ranging from a median of 382 days in those treated with a combination of craniotomy, radiotherapy (RT), and temozolomide (TZM), to 43 days in those only receiving a burr hole biopsy with no further treatment. On multivariable analysis, treatment with RT + TZM was significantly independently associated with longer patient survival (P < 0.001). Craniotomy was associated with a significant improvement in performance status, compared to burr hole biopsy (P = 0.006). For the subgroup of patients receiving TZM, those with a methylated O6-methylguanine-DNA-methyltransferase (MGMT) status had significantly longer overall survival than those with unmethylated MGMT (median: 407 vs. 341 days, P = 0.039).

Conclusion:

Our retrospective data demonstrate that the elderly population with GB benefit from aggressive chemo-RT, regardless of surgical intervention.

Authors: Herlisanto Mochammad Alnico , Mustofa Ali , Retnaningdyah Pratiwi
Published: July 2022

Jacob and Wilhelm Grimm are two of the most famous fairy tale writers with Children's and Household Tales (de: Kinder- und Hausmärchen) which have been popular over the last decades and are still read by the average people today. However, each story in their collection are rarely depicted an untroubled relationship between mother and child. The category of mothers inside these tales are traditionally divided into the positive mother figures, particularly for giving and creating life, protecting, feeding and nurturing their children; and conversely for the negative types of mother who starve their children and threaten to eat them. This study further aims to analyze the students' perceptions of women stereotypes through the tales of the Grimm Brothers. While the data was gathered through questionnaire and document analysis. The finding shows that students as participants have explored the perceptions surrounding these fairy tales that their mother figure are very weak and the women who become mothers do not care for and even neglect their children. This further attracts the researcher to immediately reveal the discord and competition between mother and child, especially daughters, which causes the unhealthy relationship of these two people.

Authors: Yamin Moh. , Purwati Oikurema
Published: July 2022

English at present is not viewed as a foreign language concerning global needs that should be learned and understood by students with isolation. Therefore, English undergoes shifting from foreign into international language or English as International Language (EIL). This paper describes the importance of EIL teaching to Indonesian students through innovative pedagogy as an effort to speed their English competence in written and spoken. At present theories and research studies dealing with EIL and innovative pedagogies are presented. All confirm that it is time to teach EIL to make the students having their identity although they use English. In EIL, students respect the local identity while learning English. Innovative pedagogy is the instruction strategy to make the students interactive and interested in English. Hence, the teachers’ role in teaching English through innovative pedagogy is required. Teachers should use the students’ environment as teaching material with global knowledge.

A Literature Review Study on Origin and Spatial Significance of Sondolmok
Authors:   Institute For Kyeongki Cultural Studies, Kim Se Ho
Published: July 2022

Sondolmok is a waterway for ship passage located in Sinan-ri, Daegot-myeon, Gimpo-si, Gyeonggi-do. In the Goryeo era, it was called Chakryang(窄梁) or Geubsumun(急水門), and it was recorded as Sondolhang(孫乭項) or Sonseokhang (孫石項) in the literature from the Joseon era. Regarding the place name of Sondolmok, the following legend has been passed down. In the process of the king moving to Ganghwa Island(江華島) for safety from the war during the Goryeo era, Son Dol, who was a boatman, was killed under a false accusation. At the moment of his death, a wind caused by his resentment blew and people called it the Sondol Wind(孫突風), and the custom of performing an ancestral rites to comfort his soul on October 20, the anniversary of his death, has been passed down up to now. Although Sondolmok has been mentioned in many past literatures, research and analysis to compile them have been limited. It is estimated that Sondolmok was called by its present name from the late Joseon era. Afterwards, Yeojidoseo(輿地圖書) introduced its origin, and Joseon era's novels, through their own historical demonstration, offered various opinions, such as claiming that the origin was merely a legend. Nevertheless, the legend of Sondolmok seems to have been steadily passed down by the local people, and it has been established as a culture by modern times. Sondolmok reappeared on the stage of history due to its characteristic topography. In the early Joseon era, construction of a canal was considered to avoid the waterway of Sondolmok, and by the late Korean Empire, it was regarded as an important point of defense of the region. As shown in above, Sondolmok's image was formed in various ways through ancient poetry that sang this place. It is expected that the above results make a small contribution to revealing the historical and cultural value of Sondolmok.
The Nationwide Spread of Japanese Theater and Local Cultural Field after Opening of the Port - Based on the list of Japanese-owned theaters -
Authors:   Institute For Kyeongki Cultural Studies, Lee Hee-Hwan
Published: July 2022

This study aimed to empirically investigate the process of forming Japanese theaters in each region in the early modern era of Korea. From the opening of the port to the beginning of liberation, Japanese theaters built in colonial Joseon were first surveyed by period and region. Efforts were made to prepare a basic list for full-scale research in the future. Starting with these Japanese theaters, the historical process of establishing theaters across the country has been revealed to some extent. The cultural infrastructure called theaters in each region formed in this way played an important role in forming an independent cultural field in each region. The cultural field of each region played a dynamic role in the history of modern Korean culture as they exchanged influences with the central cultural field.

The RMG-database for chemical property prediction is presented. The RMG-database consists of curated datasets and estimators for accurately predicting parameters necessary for constructing a wide variety of chemical kinetic mechanisms, including thermodynamics, kinetics, solvation effects, and transport properties. For thermochemistry prediction, the RMG-database contains 45 libraries of thermochemical parameters with a combined 4564 entries, a group additivity scheme with nine types of corrections including radical, polycyclic and surface absorption corrections with 1580 total curated groups and parameters for a graph convolutional neural net trained using transfer learning from a set of >130,000 DFT calculations to 10,000 high-quality values. Correction schemes for solvent-solute effects, important for thermochemistry in the liquid phase, are available. They include tabled values for 195 pure solvents and 152 common solutes and a group additivity scheme for predicting the properties of arbitrary solutes. For kinetics estimation the database contains 92 libraries of kinetic parameters containing a combined 21,000 reactions and contains rate rule schemes for 87 reaction classes trained on 8655 curated training reactions. Additional libraries and estimators are available for transport properties. All of this information is easily accessible through the graphical user interface at https://rmg.mit.edu. Bulk or on-the-fly use can be facilitated by interfacing directly with the RMG Python package which can be installed from Anaconda. The RMG-database provides kineticists with easy access to estimates of the many parameters they need to model and analyze kinetic systems. This helps speed up and facilitate kinetic analysis by enabling easy hypothesis testing on pathways, by providing parameters for model construction and by providing information to check other kinetic parameters against.

Exploration, facilitates computations of thermodynamic properties of chemical species, high-pressure limit reaction rate coefficients, and pressure-dependent rate coefficient over multi-well molecular potential energy surfaces (PES) including the effects of collisional energy transfer on phenomenological kinetics. Arkane is especially flexible, computing a variety of quantities using different methods, as determined by the users. For example, it can use estimates to fill in information for molecules or reactions where quantum chemistry information is missing. The software solves the internal energy master equation for complex unimolecular reactions systems. Inputs to the software include converged electronic structure computations performed by the user using a variety of supported software packages (Gaussian, Molpro, Orca, TeraChem, Q-Chem, Psi4). The software outputs high-pressure limit rate coefficients and pressure-dependent phenomenological rate coefficients, as well as computed thermodynamic properties (enthalpy, entropy, and constant pressure heat capacity) with added energy corrections. Some of the key features of Arkane include treatment of 1D, 2D or ND hindered internal rotation modes, treatment of free internal rotation modes, quantum tunneling effect consideration (implementing the Eckart or Wigner approach), transition state theory (TST) and Rice-Ramsperger-Kassel-Marcus (RRKM) rate coefficient computations, master equation solution with three implemented methods, inverse-Laplace transform of high-pressure limit rate coefficients into the energy domain, energy corrections based on bond-additivity or isodesmic reactions, automated and efficient PES exploration, and PES sensitivity analysis. The present work describes the design of Arkane, how it should be used, and refers to the theory that it employs. Arkane is distributed via the RMG-Py software suite (https://github.com/ReactionMechanismGenerator/RMG-Py).

Authors: MacNeil Connor S. , Mendelsohn Lauren N. , Pabst Tyler P. , Chirik Paul J.
Published: July 2022

A cobalt-catalyzed reductive hydroformylation of terminal and 1,1-disubstituted alkenes is described. One-carbon homologated alcohols were synthe-sized directly from CO and H2, affording anti-Markovnikov products (34–87% yield) with exclu-sive regiocontrol (linear/branch > 99:1) for mini-mally functionalized alkenes. Irradiation of the air-stable cobalt hydride, (dcype)Co(CO)2H (dcype = dicyclohexylphosphinoethane) with blue light gen-erated the active catalyst that mediates alkene hy-droformylation and subsequent aldehyde hydro-genation. Mechanistic origins of absolute regiocon-trol were investigated by in-situ monitoring of the tandem catalytic reaction using high-pressure mul-tinuclear NMR spectroscopy.
One-pot catalysis from renewable resources: A direct route to recyclable camphor-based polycarbonates
Authors: Jiang Bo , Thomas Christophe
Published: July 2022

To solve some of the environmental problems associated with oil extraction and make plastics production sustainable, there is increasing interest in developing selective methods to convert renewable feedstocks into monomers suitable for polymer production. Here we present a catalytic one-pot synthesis of polycarbonates from renewable resources. This approach relies on the use of a commercially available magnesium catalyst that allows the coupling of diethyl carbonate with a rigid camphor-based diol. In combination with a solvent-free polymerization, this sequence can also be extended to different diols , providing direct access to a new library of unique polycarbonates. Additionally, chemical recycling of these polycarbonates could be triggered by magnesium-catalyzed methanolysis.
Quantum-based modeling of protein-ligand interaction: The complex of RutA with uracil and molecular oxygen
Authors: Polyakov Igor , Nemukhin Alexander , Domratcheva Tatiana , Kulakova Anna , Grigorenko Bella
Published: July 2022

Modern quantum-based methods are employed to model interaction of the flavin-dependent enzyme RutA with the uracil and oxygen molecules. This complex presents the structure of reactants for the chain of chemical reactions of monooxygenation in the enzyme active site, which is important in drug metabolism. In this case, application of quantum-based approaches is an essential issue, unlike conventional modeling of protein-ligand interaction with force fields using molecular mechanics and classical molecular dynamics methods. We focus on two difficult problems to characterize the structure of reactants in the RutA-FMN-O2-uracil complex, where FMN stands for the flavin mononucleotide species. First, location of a small O2 molecule in the triplet spin state in the protein cavities is required. Second, positions of both ligands, O2 and uracil, must be specified in the active site with a comparable accuracy. We show that the methods of molecular dynamics with the interaction potentials of quantum mechanics/molecular mechanics theory (QM/MM MD) allow us to characterize this complex and, in addition, to surmise possible reaction mechanism of uracil oxygenation by RutA.
Reversible Discrete-to-Extended Metal–Organic Polyhedra Trans-formation by Sulfonic Acid Surface Functionalization
Authors: Troyano Javier , Horike Satoshi , Furukawa Shuhei
Published: July 2022

Metal-organic polyhedra (MOPs) are molecular porous units in which desired functionalities can be installed with precise geometrical and compositional control. By combing two complementary chemical moieties, such as sulfonic acid group and Rh(II)-carboxylate paddlewheel, we synthesized a robust water-soluble cuboctahedral MOP with excellent features in both solution and solid state. Herein, we demonstrate that the superior chemical stability of the Rh2 unit and the elevated number of functional groups on the surface (24 per cage) result in a porous cage with high solubility and stability in water, including acidic, neutral and basic pH conditions. We also prove that the sulfonic acid-rich form of the cage can be isolated through post-synthetic acid treatment. This transformation involves an improved gas uptake capacity, and the capability to reversibly assemble the cages into a 3D metal-organic framework (MOF) structure. Likewise, this sulfonic acid functionalization provides both MOP and MOF solids with high proton conductivities (> 10-3 S cm-1), comparable to previously reported high conducting metal-organic materials. The influence of the MOP-to-MOF processing in the gas adsorption capacity indicates this structural transformation can provide materials with higher and more controllable porous properties. These results illustrate the high potential of acidic MOPs as more flexible porous building units in terms of processability, structural complexity and tunability of the properties.

Published: July 2022

Nanostructured composite electrode materials play a major role in the field of catalysis and electrochemistry. Self‐assembly of metallic nanoparticles on oxide supports via metal exsolution relies on the transport of reducible dopants towards the perovskite surface to provide accessible catalytic centers at the solid/gas interface. However, it is unclear if exsolution can be driven from the oxide bulk or if the process is limited to surfaces and interfaces, where strong electrostatic gradients and space charges typically control the properties of oxides. Here we reveal that the nature of the surface‐dopant interaction is the main determining factor for the exsolution kinetics of nickel in SrTi0.9Nb0.05Ni0.05O3‐ẟ and that the exsolution depth is strongly limited to the near‐surface region of the perovskite oxide. Electrostatic interaction of dopants with surface space charge regions forming upon thermal annealing result in strong surface passivation i.e. a retarded exsolution response. We furthermore demonstrate the controllability of the exsolution response via engineering of the perovskite surface chemistry. Our findings indicate that tailoring the electrostatic gradients at the perovskite surface is an essential step to improve exsolution type materials in catalytic converters.

A Distributed Model for Computing 3D Mesh Local Descriptors Based on k-Rings
Authors: Suni-Lopez Franci , Hurtado Jan , Márquez Alejandra , Guzmán Leonardo
Published: July 2022

In order to facilitate 3D object processing, it is common to use high-level representations such as local descriptors that are usually computed using defined neighborhoods. K-rings, a technique to define them, is widely used by several methods. In this work, we propose a model for the distributed computation of local descriptors over 3D triangular meshes, using the concept of k-rings. In our experiments, we measure the performance of our model on huge meshes, evaluating the speedup, the scalability, and the descriptor computation time. We show the optimal configuration of our model for the cluster we implemented and the linear growth of computation time regarding the mesh size and the number of rings. We used the Harris response, which describes the saliency of the object, for our tests.

The Urban Vernacular: A low-cost incremental housing development in the Philippines
Authors:   , Manlalo Erika
Published: July 2022

This study investigates adaptable housing design as a solution to informal settlements’ issues, including the threat of rapid urbanisation and displacement due to eviction, flooding, and an array of man-made destruction. This study aims to identify design processes and solutions that support and prioritise the housing and community needs of lower-income demographics so they may live safe and healthy lives empowered by adaptable design and construction processes that put them in control of the development and progress of their living environments. This exploration will be grounded in the informal settlements of Baseco, Manila in the Philippines, one of the most densely populated in the country, where urban regeneration has been prominent over the past few years. This study will use a mix of quantitative and qualitative design research methods. This research will use quantitative data in the earlier phases of data collection to build an accurate context as a basis for exploration and understanding. Ethnographic studies will inform design phases through secondary sources supported by simulations and models. This investigation aims to contribute to the discussion of urban regeneration and solving informal housing issues in-situ to keep existing social networks intact rather than relocation. This process will begin through an adaptable building design inspired by the incrementalism of informal construction, argued as a form of urban vernacular. This paper indicates that low-income communities are reactive rather than proactive in responding to vulnerabilities. The design solution aims to be a catalyst in fostering a more proactive approach to risk-mitigation strategies and empowering communities through safer living conditions that prevent displacement that destroy networks of social connection.
