O mundo como persuasão e retórica de Carlo Michelstaedter
Authors: Ciracì Fabio
Published: January 2022

Esta contribuição visa apresentar brevemente a vida e a obra do filósofo italiano Carlo Michelstaedter (Gorizia, 3 de junho de 1887 - Gorizia, 17 de outubro de 1910), famoso autor do livro A Persuasão e Retórica, que cometeu suicídio aos vinte e três anos de idade. Em particular, este ensaio focaliza a relação entre a filosofia de Schopenhauer e a de Michelstaedter, a fim de explicar em que sentido ele deve ser considerado um “schopenhaueriano irregular”.
Effects of various insecticides on ragweed leaf beetle, Ophraella communa (Coleoptera: Chrysomelidae)
Authors: Tamaš Nenad , Sretenović Marko , Miletić Novica
Published: January 2022

In a laboratory screening test, the effects of acetamiprid, lambda-cyhalothrin, abamectin, phosmet and chlorantraniliprole on ragweed leaf beetle (Ophraella communa LeSage) were examined. The aim was to investigate their selectivity for this species in crops and orchards where they are used, and to test the possibility of their application in case of its appearance on cultivated sunflower in order to prevent damage. Commercial insecticidal formulations were used, in doses recommended for the control of a related species, Colorado potato beetle. The experiment was performed according to a standard, partially adapted method for determining the sensitivity of the Colorado potato beetle to insecticides. Based on the test results, it was determined that lambda-cyhalothrin, abamectin and phosmet are non-selective for this species, causing high mortality of individuals (100%). Weaker effects (mortality of 88.16% to 89.39%) were shown for acetamiprid, and its effect on this insect species can be assessed as weakly selective. Chlorantraniliprole showed some selectivity and very poor efficacy in O. communa control (mortality of 40.79% to 45.45%). Its application in crops and orchards would not significantly reduce the number of ragweed leaf beetles.

Drift is the movement of plant protection product droplets through the air and can affect any non-target organism or the environment. In fact, there are three possible scenarios that can be considered as an off-target movement: particle drift, volatility, and contamination of the spray tank. Significant damages that can occur as a consequence of drift are damages to neighbouring crops, environmental pollution, lower level of efficiency of the applied herbicide. Meanwhile, in the case of tank contamination, injuries can occur only in the treated field. In order to examine the negative consequences of nicosulfuron drift, four crops were grown in a greenhouse and treated with low doses of herbicide, after which they were returned to cultivation. After 21 days, the effects of applied treatments were assessed through visual assessment of injury, dry weight, leaf height, and leaf area. Based on the obtained results, it can be concluded that low doses of nicosulfuron expressed different effects on the tested plants and that it is necessary to take precautionary measures to prevent herbicides from spreading to neighbouring plants.
Is correlation between plasma and salivary cortisol levels an important indicator of stress?: A meta-analysis study
Authors: Köksal Burcu
Published: January 2022

The purpose of this study was to examine the practical importance of the correlation values between plasma and salivary cortisol levels using meta-analysis study. In this way, researchers focusing on cortisol levels in different individuals can use more systemic, practical and reliable evidence than using just salivary or plasma cortisol levels separately. For this purpose, correlational studies from 2000 up to now were collected and analyzed by meta-analysis. Results based on 18 effect sizes (n = 743) revealed that effect sizes of the correlations between plasma and salivary cortisol levels represented large effects. The overall combined effect size (Hedges's = 1.55) also represented a large effect. This finding indicates the practical importance of the correlation values for stress studies. The use of the correlation values for examining the cortisol levels in stress studies will be discussed in detail.

In this paper various complex signal constellations are considered in the context of Automatic Modulation Classification (AMC) based on a higher-order normalized cumulants value. Most of the constellations have been addressed so far with fourth-order cumulants as AMC features only. The goal of this paper is to provide comparable values of sixth-order cumulants' statistics for complex signal constellations as well, while resolving ambiguity in constellation shapes addressed at the same time and directing towards the criterion for estimation of expected classification performance.
Protocolo y ceremonial en la comunidad islámica
Authors: Somavila Enrique
Published: January 2022

La religión musulmana fue uno de los acontecimientos más trascendentales de la historia de la humanidad cuando aparece, durante el primer tercio del siglo VII, otorgando un nuevo sistema político. Económico, social y religioso, que nace en el mismo corazón de la península Arábiga y, en poco más de cincuenta años, se extendió desde el Atlántico hasta la India, de Oriente a Occidente. Todos esos pueblos recogieron en ese vasto espacio un mismo idioma común que era el árabe y al mismo tiempo profesaban un mismo credo religioso llamado Islam. La vida de los creyentes musulmanes está marcada por las oraciones, desde el nacimiento hasta el instante de la muerte. Es costumbre susurrar al oído tanto de los recién nacidos como las agonizantes frases del Corán. Su protocolo es muy variado, pues depende de la cultura de cada país.

María Zambrano y el sueño creador
Authors: Zacarés Pamblanco María Amparo , Mascarell Dauder Rosa
Published: January 2022

El 6 de febrero del 2021 se cumplieron los 30 años del fallecimiento de María Zambrano (Vélez-Málaga, 1904 - Madrid 1991), considerada la filósofa de la Generación del 27. Su reivindicación de la razón poética supuso un giro epistemológico y estético en el pensamiento español del siglo XX. Las autoras del presente artículo han coordinado y/o participado en diferentes actividades relacionadas con el recuerdo de la filósofa en una fecha tan destacada. El objetivo de este artículo es realizar un balance de dichas actividades aportando una visión de futuro del pensamiento de María Zambrano que tanto fruto ha dado, da y dará en el terreno de la creación artística y del pensamiento crítico, poniendo como ejemplo especialmente la pintura de Mery Sales y la obra de teatro La tumba de María Zambrano de Nieves Rodríguez y Jana Pacheco. Para ello queremos incidir en la variedad y profundidad del pensamiento de María Zambrano en diferentes ámbitos del saber, siendo la estética uno de los fundamentales. Apuntamos también como fundamental para el pensamiento crítico, la revisión que la propia filósofa realizó de dos figuras femeninas claves como son Antígona y Diótima, convirtiéndolas en referentes de absoluta actualidad para realizar una revisión del momento presente en el que las voces femeninas siguen siendo usurpadas o silenciadas bajo diferentes pretextos que no son más que un fraude cultural.

Abstract
The 6th of February of 2021 marked the 30th anniversary of the passing of María Zambrano (Vélez-Málaga, 1904 – Madrid 1991), considered the only philosopher of the Generation of ‘27. Her vindication of poetic reason was an epistemic and aesthetic turn in 20th-century Spanish thought. The authors of this article have coordinated and/or participated in different activities related to the memory of the philosopher at such an important date. The purpose of the article is to provide a survey of such activities. It provides a future-looking vision of Zambrano’s thought, which already has contributed so much – and will continue to do so – to artistic production and critical thought, focusing on the examples provided by the painting of Mery Sales and the play Maria Zambrano’s Tomb, by Nieves Rodríguez y Jana Pacheco. To this end, we want to insist in the variety and depth of María Zambrano’s thought in different fields of knowledge, aesthetics being a fundamental one. We also highlight the revision carried out by the philosopher of two key female figures, Antigone and Diotima, turning them into examples of absolute relevance for rethinking the present moment, a time when female voices continue to be usurped and silenced under different pretexts, resulting in nothing less than cultural fraud.

Poner la reversa en el sentimiento, el pensamiento y la acción
Authors: Arnold Rolf
Published: January 2022

La temática es todo menos nueva; pero hoy parece estar más ineludiblemente «clarificada» que en épocas anteriores: desde los trabajos de la epistemología biológica y los conocimientos más recientes sobre el funcionamiento de la percepción humana o sobre el desarrollo, cambio y adaptación de los patrones de la interpretación y emocionales, la postura conservadora de la orientación humana surgió aún más claramente como una «conquista» evolutiva, pero también como una restricción interna a lo posible: en nuestros sentimientos, pensamientos y acciones siempre nos esforzamos por permanecer en gran medida tal como somos y no vemos el mundo «así como es, sino como somos» (Talmud).

¡La memética ha muerto: larga vida a la memética!
Authors: Sañé Díaz-Santos Francesc
Published: January 2022

El presente ensayo tiene como propósito preguntarse por el estado de la memética hoy en día desde la filosofía. El objetivo es dar suficientes motivos para reconsiderar un giro de 180º a su enfoque, sacándola de su pregunta ontológica y poniendo el foco en la crítica político-ideológica. En el complejo escenario socio-digital, los memes emergen como el lugar de enunciación de un logos que no puede ser ignorado. Un meme nunca es solo un meme, y quizás esto haga temblar los cimientos de las instituciones académicas e incluso vaticinar una inflexión en la historia del pensamiento.
Sobre la concepción de lo religioso en Wittgenstein: Un socioanálisis
Authors: Rocher Quintairos Fernando
Published: January 2022

Con motivo del centenario de la publicación del Tractatus Logico-philosophicus, esta ocasión pone de nuevo en relevancia a una de las grandes figuras de la filosofía del siglo XX, Ludwig Wittgenstein. Este autor, de manera directa o indirecta, ha realizado aportaciones no solo a la filosofía, sino a una gran variedad de ramas de pensamiento, entre ellas a las ciencias sociales. No obstante, y paradójicamente, las ciencias sociales en general, y la sociología en especial, no han prestado mucha atención a Wittgenstein más allá de algunos aspectos epistemológicos y metodológicos de su filosofía. Es por ello que consideramos que un estudio específicamente sociológico sobre la figura personal de Wittgenstein, enlazado con su concepción filosófica, podría servir para aportar mayor claridad y comprensión conceptual a estos mismos planteamientos wittgensteinianos que las ciencias sociales han adoptado dentro de sus teorías e investigaciones.
The peculiarities of normative legal regulation of the official structure of civil service of the Republic of Kazakhstan
Authors: Semin Aleksei
Published: January 2022

This article explores the peculiarities of legal regulation of the official structure of civil service of the Republic of Kazakhstan. The author determines the characteristic of the current stage of development of the institution of civil service, and conducts their assessment from the perspective of the impact of various models of arrangement and functionality of the system of civil service. Particular attention is given to the terminological framework and essential content of the key categories of this institution. The author differentiates the concepts of “state civil service of the Russian Federation”, “state service of the Republic of Kazakhstan, and “civil service of the Republic of Kazakhstan”. The application of comparative- legal and formal-legal methods allow establishing correlation between the political and administrative posts in civil service of the Republic of Kazakhstan on the one hand and state positions and positions of the civil service of the Russian Federation on the other hand; and public office and posts in civil service of the Russian Federation on the other hand. The conclusion is made on the substantial differences not only in the official structure of civil service, but in the official structure of public administration in both countries as well. The article also outlines a range of problems in the normative legal regulation of the official structure of civil service of the Republic of Kazakhstan. It is proven that the direct comparison of the official structures of public administration and civil service of the two countries is impossible due to significant difference in the terminological framework and general principles of formation of the official structures. Taking into account the common historical base – the uniform system of civil service of the Soviet Union, such a difference may testify to multidirectional trends in the development of the systems of civil service in the Russian Federation and the Republic of Kazakhstan.

Authors: Bulatov Gasan Islamovich , Abdalla Bashir Khamid , Khalil' Khussian Mokhammed
Published: January 2022

This article analyzes the concerns and prospects for the development of relations between Turkey and Germany based on the historical method and event study. The relevance of this topic lies in the fact that at the in the context of transition of the global political system from bilateral to multilateral model of world political landscape, Turkey’s political interests are focused on becoming one of the dominants in the Caucasus-Black Sea-Mediterranean region. The article discusses the complicated relations between Germany and Turkey. Special attention is given to the domestic political agenda of the two countries, their bilateral relations, as well as relations with the European Union. Various political parties in Germany, their outlook upon Germany-Turkey and EU-Turkey relations, positioning on the German Turks, and policy of the German governments are described from the perspective of historical approach to shed light on the key aspects of their attitude towards the “Turkish issue”. The article outlines the trends and prospects for the evolution of Germany-Turkey relations at the current stage of development of the world political-economic system. The conducted analysis relies on the authorial fundamental works, scientific publications, and historical documents on the history of Germany-Turkey relations. Using the three-tier analysis of bilateral visits of the representatives of both countries over the period from 2014 to 2020, the author places emphasis on the domestic political agenda of the two countries, bilateral relations between them, as well as their relations with the European Union.
Foreign policy priorities of the United States in Asia-Pacific: impact of the concepts “Pivot to Asia” and “America First”
Authors: Novoseltsev Sergey Vladimirovich , Ryzhov Igor' Valer'evich
Published: January 2022

This article analyzes the influence of the United States upon the political processes in APAC based on the example of territorial disputes in the South China Sea. An overview is given to the foreign policy concepts “Pivot to Asia” and “America First” proposed by the administrations of B. Obama and D. Trump respectively, the priorities outlined therein, as well as importance of the  conflict in the South China Sea for the US foreign policy. The author examines the practical steps taken by Washington in relation to the South China Sea question, as well as concludes on the objectives of the United States and possible steps in this direction. Although the theme of territorial disputes in the South China Sea, including the degree of  involvement of Washington into this issue, as well as other East Asian affairs, is quite popular in the scientific works,  the novelty of this research consists in the innovative approach towards consideration of the conflict in the South China Sea not as a separate problem of international relations, but as the foreign policy instrument of superpower and regional powers (including the United States) used for formatting the East Asian regional subsystem of international relations and structuring the Greater East Asia macroregion to their benefit.
Who is an expert? A corpus-assisted analysis of the expert in Swedish Covid-19 discourse
Authors: Ängsal Magnus P.
Published: January 2022

This article explores a prevalent thematic strand of the Swedish public discourse on Covid-19 pandemic strategies. Analyzing the construction and role of the expert as it has been played out in the news media coverage of Covid-19 in four leading Swedish daily newspapers throughout the first two months of the pandemic in 2020 (February and March), the contribution asks who counts as a trustworthy expert, and to what extent such ascriptions are used in debates about the Swedish coronavirus strategy, which has aroused much interest and criticism. One of the important findings is the concept of a reliable and rational expert who is, primarily, a Swedish epidemiologist. Also noteworthy is the fact that the role of the expert and the very word expert seem to be under negotiation. This contribution is situated within the framework of discourse linguistics and explores segments of discourse understood as collectively shared knowledge. A partly corpus-assisted methodology is used. The study aims to link linguistic utterances on the expert’s role in the pandemic with the level of important social actors in the course of the pandemic in Sweden.

Authors: Tian Zhi-Fu , Wu Di , Hu Tao ,   College of Data and Target Engineering, PLA Strategic Support Force Information Engineering University, Zhengzhou 450000, China
Published: January 2022

To examine the single-photon quantum radar cross-section of cylindrical surface and its specific advantages over the classical radar cross-section, a photon wave function in which the distance vectors causing interference are decomposed is introduced in this study. A closed-form expression of the single-photon quantum radar cross-section of cylindrical surface is derived. The influences of the length and curvature radius of cylindrical surfaces with different electrical sizes are analyzed, and the closed-form expressions of the quantum and classical radar cross-sections of cylindrical surface are compared with each other. The analyses of the closed-form expression and simulation results show that the electrical length of the cylindrical surface determines the number of side lobes of the quantum radar cross-section; meanwhile, the curvature radius has a linear relation with the overall strength of the quantum radar cross-section, and the electrical size of the curvature radius determines the envelope of the quantum radar cross-section curve. Compared with the classical radar cross-section, the quantum radar cross-section of a cylindrical surface has the advantage of side-lobe enhancement, which is beneficial for detecting stealth targets.
Ultracold atom-atom collisions by renormalized Numerov method
Authors: Bai Jing , Xie Ting ,   Department of Electronic and Electrical Engineering, Dalian Vocation & Technical College, Dalian 116035, China,   State Key Laboratory of Molecular Reaction Dynamics, Dalian Institute of Chemical Physics, Chinese Academy of Sciences, Dalian 116023, China
Published: January 2022

The renormalized Numerov algorithm is applied to solving time-independent Schrödinger equation relating to atom-atom collisions at ultralow temperature. The proprieties of Feshbach resonance in 39K-133Cs collisions are investigated as an example. The results show that the renormalized Numerov method can give excellent results for ultracold colliding process. In contrast to improved log derivative method, the renormalized Numerov method displays a certain weakness in computational efficiency under the same condition. However, it is much stable in a wide range of grid step size. Hence a new propagating method is proposed by combining renormalized Numerov and logarithmic derivative method which can save computational time with a better accuracy. This algorithm can be used to solve close-coupling Schrödinger equation at arbitrary temperature for two-body collisions.
Narrative Inquiry as an Arena for (Polish) Caregivers’ Retelling and Re-experiencing of Norwegian Kindergarten
Authors: Sadownik Alicja
Published: January 2022

This study shows how conducting a narrative inquiry with migrant parents not only serves as a means of collecting their experiences of kindergarten services but also opens up a communicative space that allows for engagement with stories different from one’s own, and thus allows for the re-experiencing of the services provided. The presented re-experiences were ultimately found to be necessary for the participating parents to understand the values and knowledge underpinning kindergarten practices and routines, and thus to engage meaningfully and authentically with kindergartens. In the material presented, re-experiencing comprises the process of relating to the retold narrative’s temporality and sociality, which are oriented toward facilitating engagement with other people’s stories, as well as with one’s own and others from the past. The conclusion drawn was that the communicative spaces created through narrative inquiry have the potential to support kindergarten’s work in enhancing authentic partnerships with (particularly migrant) parents and addressing the democratic deficit in the involvement of (migrant) parents. Diverse ways of using narrative inquiry as facilitating parental engagement in the synergy between academia and the early childhood education sector are also reviewed.
A three-stage heuristic task scheduling for optimizing the service level agreement satisfaction in device-edge-cloud cooperative computing
Authors: Sang Yongxuan , Cheng Junqiang , Wang Bo , Chen Ming
Published: January 2022

Device-edge-cloud cooperative computing is increasingly popular as it can effectively address the problem of the resource scarcity of user devices. It is one of the most challenging issues to improve the resource efficiency by task scheduling in such computing environments. Existing works used limited resources of devices and edge servers in preference, which can lead to not full use of the abundance of cloud resources. This article studies the task scheduling problem to optimize the service level agreement satisfaction in terms of the number of tasks whose hard-deadlines are met for device-edge-cloud cooperative computing. This article first formulates the problem into a binary nonlinear programming, and then proposes a heuristic scheduling method with three stages to solve the problem in polynomial time. The first stage is trying to fully exploit the abundant cloud resources, by pre-scheduling user tasks in the resource priority order of clouds, edge servers, and local devices. In the second stage, the proposed heuristic method reschedules some tasks from edges to devices, to provide more available shared edge resources for other tasks cannot be completed locally, and schedules these tasks to edge servers. At the last stage, our method reschedules as many tasks as possible from clouds to edges or devices, to improve the resource cost. Experiment results show that our method has up to 59% better performance in service level agreement satisfaction without decreasing the resource efficiency, compared with eight of classical methods and state-of-the-art methods.
A review of the common crab genus Macromedaeus Ward, 1942 (Brachyura, Xanthidae) from China Seas with description of a new species using integrative taxonomy methods
Authors: Yuan Ziming , Jiang Wei , Sha Zhongli
Published: January 2022

Macromedaeus is one of the most common xanthid genera in shallow waters of the Indo-West Pacific. In this study, we describe a new species, Macromedaeus hainanensis sp. nov., and report on two newly recorded species, M. quinquedentatus (Krauss, 1843) and M. orientalis (Takeda & Miyake, 1969) from Hainan Island, South China Sea. M. hainanensis is most related to M. distinguendus (De Haan, 1833-1850) and M. orientalis on the carapace shape and granular appearance, but can be distinguished by unique morphological characteristics especially its front, pereopods and male first gonopod. Taxonomic identities of the six Macromedaeus species recorded from China seas are discussed, and a phylogenetic analyzation is performed on Macromedaeus and related taxa based on three mitochondrial and two nuclear markers (12S, 16S, COI, H3, 18S). Integrated taxonomic evidence is used to support the taxonomic status of each species.
Genome survey sequencing of the phyto-parasitic nematode Hoplolaimus galeatus
Authors: Ma Xinyuan , Agudelo Paula , Richards Vincent P. , Baeza J. Antonio
Published: January 2022

Background

Hoplolaimus galeatus is a plant-parasite nematode with a broad range of hosts. This nematode is known to damage cotton, corn, and soybean crops. Hoplolaimus galeatus is also an economically important pest of turfgrasses. Despite its economical importance, no genomic resources exist for this parasite.

Methods

Using 300 bp paired-end short read sequencing, this study estimated genome size, analyzed a nearly complete mitochondrial chromosome, and explored nuclear repetitive elements, including microsatellites, in H. galeatus for the first time. The phylogenetic placement of H. galeatus in the superfamily Tylenchoidea was also examined.

Results

The average haploid genome size estimated using a k-mer approach was 517.69 Mbp. The partially assembled mitochondrial genome of H. galeatus is 16,578 bp in length and comprised of 11 protein-coding genes, two ribosomal RNA genes, and 16 transfer RNA genes. A maximum likelihood phylogenetic analysis confirmed the monophyly of the genus Hoplolaimus and the superfamily Tylenchoidea. Repetitive elements constituted  50% of the nuclear genome while half of the genome represented single- or low-copy sequences. A large portion of repetitive sequences could not be assigned to known repeat element families. Considering only annotated repetitive elements, the most ubiquitous belonged to Class II- Subclass 2-Maverick elements, Class I-LTR-Ty-3/Bel-Pao elements, and satellites. 45S ribosomal DNA was also abundant and a total of 36 SSRs were identified.This study developed genomic resources for the plant-parasitic nematode Hoplolaimus galeatus that will contribute to the better understanding of meta-population connectivity and putative genomic mechanisms involved in the exploitation of the broad range of host plants used by H. galeatus.
Morphological and biochemical responses of tropical seagrasses (Family: Hydrocharitaceae) under colonization of the macroalgae Ulva reticulata Forsskål
Authors: Emmclan Lau Sheng Hann , Zakaria Muta Harah , Ramaiya Shiamala Devi , Natrah Ikhsan , Bujang Japar Sidik
Published: January 2022

Background

Coastal land development has deteriorated the habitat and water quality for seagrass growth and causes the proliferation of opportunist macroalgae that can potentially affect them physically and biochemically. The present study investigates the morphological and biochemical responses of seagrass from the Hydrocharitaceae family under the macroalgal bloom of Ulva reticulata, induced by land reclamation activities for constructing artificial islands.

Methods

Five seagrass species, Enhalus acoroides, Thalassia hemprichii, Halophila ovalis, Halophila major, and Halophila spinulosa were collected at an Ulva reticulata-colonized site (MA) shoal and a non-Ulva reticulata-colonized site (MC) shoal at Sungai Pulai estuary, Johor, Malaysia. Morphometry of shoots comprising leaf length (LL), leaf width (LW), leaf sheath length (LSL), leaflet length (LTL), leaflet width (LTW), petiole length (PL), space between intra-marginal veins (IV) of leaf, cross vein angle (CVA) of leaf, number of the cross vein (NOC), number of the leaf (NOL) and number of the leaflet (NOLT) were measured on fresh seagrass specimens. Moreover, in-situ water quality and water nutrient content were also recorded. Seagrass extracts in methanol were assessed for total phenolic content (TPC), total flavonoid content (TFC), 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity (DPPH), 2,2′-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid radical cation scavenging activity (ABTS), and ferric reducing antioxidant power (FRAP).

Results

Seagrasses in the U. reticulata-colonized site (MA) had significantly higher (t-test, p < 0.05) leaf dimensions compared to those at the non-U. reticulata colonized site (MC). Simple broad-leaved seagrass of H. major and H. ovalis were highly sensitive to the colonization of U. reticulata, which resulted in higher morphometric variation (t-test, p < 0.05) including LL, PL, LW, and IV. Concerning the biochemical properties, all the seagrasses at MA recorded significantly higher (t-test, p < 0.05) TPC, TFC, and ABTS and lower DPPH and FRAP activities compared to those at MC. Hydrocharitaceae seagrass experience positive changes in leaf morphology features and metabolite contents when shaded by U. reticulata. Researching the synergistic effect of anthropogenic nutrient loads on the interaction between seagrasses and macroalgae can provide valuable information to decrease the negative effect of macroalgae blooms on seagrasses in the tropical meadow.

La pandemia del Sars-CoV-2 vino no solo a revolucionar nuestra forma de vivir, sino también de morir. Esta crisis sanitaria, cuyo costo humano posiblemente aún no logramos dimensionar, fue capaz de hacer visible el sufrimiento y la muerte vivida por quienes sucumbían ante este nuevo virus a toda la sociedad. Para el personal sanitario, esta situación lo enfrentó a la realidad de la muerte desnuda, pasando a estar a cargo no solo del cuidado físico de la persona, el más habitualmente abordado, sino también de su acompañamiento emocional, social y espiritual hasta su último respiro.

Introduction: Aging is associated with a variety of functional, demographic and immunologic changes, responsible for increasing the incidence and severity of infectious diseases in the elderly. Aim: To examine the association of serum 25-hydroxy vitamin D status with antimicrobial activity of cultured macrophages isolated within an exclusively elderly population cohort and also to examine the effect of in-vitro 1,25 hydroxy vitamin D supplementation in it. Materials and Methods: This experimental study was conducted among 113 elderly women aged between 60 to 70 years of age, during the period of April 2014 to August 2018, at Amdanga block, North 24th Parganas, West Bengal, India. Their vitamin D status was assessed by the estimation of serum 25-hydroxy vitamin D and classified into three groups, sufficient group (60 subjects), insufficient group (27 subjects) and deficient group (26 subjects). Later their Peripheral Blood Mononuclear Cells (PBMC) were isolated and cultured from fresh blood of each and every study subject. Supplementation of 1,25 dihydroxy vitamin D {1,25(OH)2D} was given selectively at a dose of 10×10-8 M for 72 hours in the culture media and were exposed to Vibrio cholerae and inducible nitric oxide synthase (iNOS), Superoxide Dismutase (SOD) activity and Bactericidal activity were screened. Statistical Package for the Social Sciences (SPSS) software, version 20.0 was used to perform statistical analysis. Results: The sufficient group iNOS activity had significantly higher than the other two groups. Whereas in-vitro 1, 25(OH)2D supplementation increases iNOS activity significantly among all three groups. As per the Colony Forming Unit (CFU) reduction rate against Vibrio cholerae infection the sufficient serum 25(OH)D consisting group had significantly (p-value=0.03) high CFU reduction rate than the other two groups. Although in-vitro 1, 25(OH)2D supplementation had no significant impact on CFU reduction rate among all three groups. Conclusion: Bacteria killing capacity of macrophages varies significantly with serum 25-hydroxy vitamin D level of the target population. Sufficient group macrophages always had better profile than other two groups. In-vitro 1, 25(OH)2D supplementation increases iNOS and SOD activity significantly.

Introduction: Kangaroo Mother Care (KMC) is a simple method of caring Low Birth Weight (LBW) babies with a birth weight below 2500 grams. The grandmothers play a key role in child rearing in the Indian society. Aim: To estimate the level of knowledge about the KMC in the grandmothers and to compare it with that of the mothers. Materials and Methods: The cross-sectional study was conducted in the neonatal follow-up clinic of a tertiary care hospital with a convenience sampling of all the mother (Group 1) and grandmother (Group 2) dyads. The mothers and grandmothers were interviewed separately using a pre-validated questionnaire with 15 open ended questions to assess the knowledge about the KMC. Mann-Whitney U test and Fischer’s- exact test were used for statistical analysis. Results: There were 390 mother- grandmother dyads in the study group. The mean age of the mothers and grandmothers were 24.69±1.54 years and 53.89±1.80 years, respectively. For all the 15 questions the grandmothers had a significantly lower score when compared to the mothers (p<0.001). The grandmothers (mean score: 8.48±2.00) had a significantly lower overall knowledge scores than the mothers (mean score: 23.10±1.55). On comparison of the mean knowledge scores of the mothers with their age, educational status and socio- economic class, it was found to be independent of these factors (p-value=0.209, 0.691 and 0.731, respectively). Conclusion: This study had demonstrated that the grandmothers have a significantly lower knowledge about KMC. There is an urgent need to empower them with the knowledge about KMC for the successful continuation KMC in the home.

Introduction: Diabetes Mellitus (DM) is a global health problem and India is the capital of it. It leads to acute metabolic and long-term complications with high morbidity and mortality. Cardiovascular (CV) disease is the major cause of mortality. Microalbuminuria (MAU) has been associated with generalised vasculopathy in major organ systems. Left Ventricular (LV) dysfunction and premature onset of CV disease is predicted by MAU. Aim: To evaluate the correlation of degree of microalbuminuria in Type 2 Diabetes Mellitus (Type2DM) as a predictor of LV dysfunction. Materials and Methods: This was a cohort study conducted in the Outpatient Department (OPD) of Medicine on 251 patients clinically diagnosed with Type2DM. Subjects were selected as per American Diabetic Association (ADA) criteria and cases having hypertension Ischaemic Heart Disease (IHD), valvular heart disease, Chronic Kidney Disease (CKD), Urinary Tract Infection (UTI), Chronic Liver Disease (CLD) were excluded from the study. MAU was assessed as having persistent albuminuria in two out of three urine samples as (30-300 mg/day or 20- 200 microgram per mg or an albumin creatinine ratio of 30- 300 microgram per mg creatinine). Echocardiogram to assess LV function were done in the Department of Cardiology using dual mode real time, 213/M-Mode, colour doppler, pulsed web doppler, continuous web doppler, considering criteria of American Society of Echocardiography and Mayo Clinic criteria. Data was analysed by Unpaired t-test for normal data, Chi-square test for dichotomous data and values were correlated using Pearson’s correlation coefficient. Results: Out of 251 study subjects, 148 were males and 103 were females with male to female ratio of 1.43:1. MAU was positive in 24.7% cases out of 251 cases. Echocardiogram revealed 77.4%% of study population have LV dysfunction and 46.8% of cases having diastolic dysfunction. With increased level of MAU, the incidence of LV diastolic dysfunction and LV systolic dysfunction also increased. In LV systolic dysfunction, severity of MAU was negatively correlated with Ejection fraction (EF), Fractional Shortening (FS), Cardiac Output (CO) and positively correlated with E Point Septal Separation (EPSS). In LV diastolic dysfunction, all parameters were positively correlated with severity of MAU. Severity of MAU and LV dysfunction were correlated and was found statistically significant (p<0.05). Conclusion: Severity of MAU was found to have significant correlation with parameters of LV systolic and diastolic function with significant p-value. LV dysfunction has also a strong correlation with poor glycaemic control and duration of DM.

Leaves of Ocimum basilicum, Leptadania hastata and Momordica balsamina are locally used by traditional birth attendants at pre and post-partum. The present study investigates the phytochemical and antimicrobial activity of the leaf extracts against isolates of L. monocytogenes. Standard microbiological techniques were used to isolate and identify the bacteria. Phytochemical analysis revealed the presence of tannins, flavonoids, carbohydrates, alkaloids, terpinoids and glycosides in the studied extracts. MIC of the extract of M. balsamina shows a total inhibition of Listeria monocytogenes at a concentration of 2,000µg/mL. No isolate was inhibited at concentration lower than 125µg/mL of M. balsamina extract. MIC of the extract against L. hastata was observed at a concentration of 2,000µg/mL. O. basilicum extract inhibited the growth of the isolates at a concentration of 2,000µg/mL. The MBC of the extracts, was between 5,000-0.61µg/mL were used, however, no antibacterial activity was observed on the bacterium with any of the three plants extracts at all concentration levels (0.61-5000πg/mL). The leaf extracts demonstrated significant inhibitory activity but lack bacteriocidal effects on L. monocytogenes. It was recommended that further studies on the preparation, effective doses and side effects of these extracts in animal models are warranted.
