Mathew, Bijo,Baek, Seung Cheol,Grace Thomas Parambi, Della,Pil Lee, Jae,Joy, Monu,Annie Rilda, P. R.,Randev, Rugma V.,Nithyamol, P.,Vijayan, Vijitha,Inasu, Sini T.,Mathew, Githa Elizabeth,Lohidakshan, The Royal Society of Chemistry 2018 MedChemComm Vol.9 No.11

<P>A series of 13 phenyl substituted thiosemicarbazones (SB1-SB13) were synthesized and evaluated for their inhibitory potential towards human recombinant monoamine oxidase A and B (MAO-A and MAO-B, respectively) and acetylcholinesterase. The solid state structure of SB4 was ascertained by the single X-ray diffraction technique. Compounds SB5 and SB11 were potent for MAO-A (IC50 1.82 ± 0.14) and MAO-B (IC50 0.27 ± 0.015 μM), respectively. Furthermore, SB11 showed a high selectivity index (SI > 37.0) for MAO-B. The effects of fluorine orientation revealed that SB11 (<I>m</I>-fluorine) showed 28.2 times higher inhibitory activity than SB12 (<I>o</I>-fluorine) against MAO-B. Furthermore, inhibitions by SB5 and SB11 against MAO-A and MAO-B, respectively, were recovered to near reference levels in reversibility experiments. Both SB5 and SB11 showed competitive inhibition modes, with <I>K</I>i values of 0.97 ± 0.042 and 0.12 ± 0.006 μM, respectively. These results indicate that SB5 and SB11 are selective, reversible and competitive inhibitors of MAO-A and MAO-B, respectively. Compounds SB5, SB7 and SB11 showed moderate inhibition against acetylcholinesterase with IC50 values of 35.35 ± 0.47, 15.61 ± 0.057 and 26.61 ± 0.338 μM, respectively. Blood-brain barrier (BBB) permeation was studied using the parallel artificial membrane permeation assay (PAMPA) method. Molecular docking studies were carried out using AutoDock 4.2.</P>

Mathew, Aleyamma,George, Preethi Sara,Arjunan, Asha,Augustine, Paul,Kalavathy, MC,Padmakumari, G,Mathew, Beela Sarah Asian Pacific Journal of Cancer Prevention 2016 Asian Pacific journal of cancer prevention Vol.17 No.6

Background: Increasing breast cancer (BC) incidence rates have been reported from India; causal factors for this increased incidence are not understood and diagnosis is mostly in advanced stages. Trivandrum exhibits the highest BC incidence rates in India. This study aimed to estimate trends in incidence by age from 2005-2014, to predict rates through 2020 and to assess the stage at diagnosis of BC in Trivandrum. Materials and Methods: BC cases were obtained from the Population Based Cancer Registry, Trivandrum. Distribution of stage at diagnosis and incidence rates of BC [Age-specific (ASpR), crude (CR) and age-standardized (ASR)] are described and employed with a joinpoint regression model to estimate average annual percent changes (AAPC) and a Bayesian model to estimate predictive rates. Results: BC accounts for 31% (2681/8737) of all female cancers in Trivandrum. Thirty-five percent (944/2681) are <50 years of age and only 9% present with stage I disease. Average age increased from 53 to 56.4 years (p=0.0001), CR (per $10^5$ women) increased from 39 (ASR: 35.2) to 55.4 (ASR: 43.4), AAPC for CR was 5.0 (p=0.001) and ASR was 3.1 (p=0.001). Rates increased from 50 years. Predicted ASpR is 174 in 50-59 years, 231 in > 60 years and overall CR is 80 (ASR: 57) for 2019-20. Conclusions: BC, mostly diagnosed in advanced stages, is rising rapidly in South India with large increases likely in the future; particularly among post-menopausal women. This increase might be due to aging and/or changes in lifestyle factors. Reasons for the increased incidence and late stage diagnosis need to be studied.

A Short Note on Inclusive and Exclusive Plurals in Korean

Michael Jonathan Mathew Barrie(Michael Jonathan Mathew Barrie ),Éric Mathieu(Éric Mathieu ) 한국생성문법학회 2023 생성문법연구 Vol.33 No.1

The aim of this short article is to give a comprehensive analysis of number in Korean, adding a novel observation about the interpretation of plurals in that language. Based on the new data, our proposal is that number is distributed along the nominal spine with different effects depending on the type of functional head (and semantic features) it is associated with. In particular, we propose that number in Korean is associated with two number projections, NumP1 and NumP2, (see Watanabe 2010 for Japanese, Vazquez Rojas Maldonado 2012 for Purépecha (isolate, tsz), Dali and Mathieu 2021 for Tunisian Arabic (Afro-Asiatic, aeb)). By shedding light on the distinction between inclusive and exclusive plurals in Korean and the relationship between definiteness and plurality, we contribute to the current debate related to the distribution of the Korean plural.

Dissecting Inchoatives and Causatives: English get constructions

Barrie Michael Jonathan Mathew,성문현 한국언어정보학회 2018 언어와 정보 Vol.22 No.3

Barrie, Michael Jonathan Mathew and Sung, Moonhyun. 2018. Dissecting Inchoatives and Causatives: English get Constructions. Language and Information, 22.3. 91-108. In this paper, we present data from English get-constructions and from Northern Iroquoian to challenge the recent consensus that in no languages are causatives built on inchoatives. Our data suggest the need for distinct functional projections for the causative and inchoative. We argue that while they are bundled in other situations, the functional heads for the causative and inchoative can be split as described in the present paper. This line of research follows recent trends in investigating the fine structure of the vP layer (Alexiadou et al. 2015, Harley 2013, Kim 2011, Marantz 2013, Pylkkänen 2008, Ramchand 2008, Legate 2014). We propose a syntactic mechanism for bundling and, in doing so, account for differences in the range of possible meanings with adverbs between canonical causatives and get-causatives. Briefly, get-causatives have unbundled causative and inchoative heads and have a wider ranger of adverbial meanings due to the projection of independent CausP and InchP. Canonical causatives have a bundled Caus-Inch head, projecting a single Caus/InchP, which leads to fewer sites for adverbs to adjoin and accordingly to a narrower range of adverbial meanings.

Mathews, Stanley,Lee, Seung-Eun The Costume Culture Association 2018 Fashion, industry and education Vol.16 No.1

The purpose of this exploratory study was to enhance the understanding of how brands tilize emojis in their marketing practices. A content analysis was conducted utilizing Google News as a search tool to access articles containing information pertaining to the use of emojis by brands. The combination of keywords used for the search were "emoji", "business", and "marketing". The search was narrowed down to the period of January $1^{st}$, 2014 - November $29^{th}$, 2017. This method generated a total of 604 trade publications with 55 of them providing information pertaining to specific brands and their use of emojis in their marketing strategies. A content analysis of trade publications has revealed that a variety of marketers have utilized emojis in their brand marketing practices. The entertainment, service, and food/drink industries have predominantly utilized emojis in their marketing practices, and their primary purpose for using emojis was to increase consumer engagement. Brands applied most of these emoji marketing strategies to an online or digital setting, whether it was social media pages, mobile applications, or any other form of computer-based marketing. Although there are limitations to this exploratory research in terms of its methodology, the findings of this study provide interesting insights into the potential of emojis as a marketing tool.

Synthesis, Characterization, and Properties of Fully Aliphatic Polyimides and Their Derivatives for Microelectronics and Optoelectronics Applications

Mathews Anu Stella,Kim Il,Ha Chang-Sik The Polymer Society of Korea 2007 Macromolecular Research Vol.15 No.2

Polyimides are one of the most important classes of polymers used in the microelectronics and photoelectronics industries. Because of their high thermal stability, chemical resistance, and good mechanical and electric properties, polyimides are often applied in photoresists, passivation and dielectric films, soft print circuit boards, and alignment films within displays. Recently, fully aliphatic and alicyclic polyimides have found applications as optoelectronics and inter layer dielectric materials, due to their good transparencies and low dielectric constants $(\varepsilon)$. The low molecular density, polarity and rare probability of forming inter- or intra-molecular charge transfers, resulting in lowering of the dielectric constant and high transparency, are the most striking characteristics of aliphatic polyimide. However, the ultimate end use of polyimides derived from aliphatic monomers is in their targeted applications that need less stringent thermal requirements. Much research effort has been exerted in the development of aliphatic polyimide with increased thermal and mechanical stabilities, while maintaining their transparencies and low dielectric constants, by the incorporation of rigid moieties. In this article, the recent research process in synthesizing fully aliphatic polyimides, with improved dimensional stability, high transparency and low $\delta$values, as well as the characterizations and future scope for their application in micro electric and photo-electronic industries, is reviewed.

C?H bond arylation of anilides inside copper-exchanged zeolites

Mathew, B.P.,Yang, H.J.,Jeon, H.,Lee, J.H.,Kim, J.C.,Shin, T.J.,Myung, K.,Kwak, S.K.,Kwak, J.H.,Hong, S.Y. Elsevier 2016 Journal of molecular catalysis Chemical Vol.417 No.-

<P>Syntheses of fine-chemicals using heterogeneous catalysts have tremendous industrial potentials, yet C-H functionalization studies have been largely focused on homogeneous catalysis. We report here the first meta-selective C-H bond arylation of anilides inside copper-exchanged zeolites. Mid- or large-pore zeolite frameworks are selected as supports to access large organic molecules, and atomically distributed copper catalysts exhibit high activities (84-90% conversions) toward direct arylation of anilides with diphenyliodonium salt on 0.5 mol% copper concentration. Computational studies indicate the well fitted copper-aryl complexes inside zeolite frameworks. Electron micrographs, elemental analyses, and reusability study show no observable leaching of catalytically active copper species during the reactions tested. These results demonstrate the practical synthetic potential of copper-exchanged zeolites as promising supported molecular catalysts to afford biaryl motifs-containing compounds with high catalytic activity, chemical stability, and recyclability.
