Retinal Nerve Fiber Layer Thickness in Multiple Sclerosis With and Without Optic Neuritis: a Four-year Follow-up Study
Authors: Al-Mujaini Abdullah S. , Al-Mujaini Maiysa S. , Sabt Buthaina I.
Published: March 2021

Background: Multiple sclerosis (MS) is an autoimmune disease that attacks the central nervous system, with optic neuritis (ON) being a common early manifestation. Retinal nerve fiber layer (RNFL) thickness may be a biomarker of neuroaxonal damage in MS patients. We sought to evaluate changes in RNFL thickness over four years in Omani MS patients with or without ON in comparison to a healthy control group. Methods: This retrospective case-control study involved 27 MS patients and 25 healthy controls. Optical coherence tomography was performed upon first diagnosis and at a four-year follow-up. Differences in mean RNFL thickness were calculated. Results: A total of 51 eyes from the MS group and 50 eyes from the control group were evaluated. There was a significant reduction in mean RNFL thickness among MS patients with ON at follow-up (81.21 versus 72.14 µm; P = .003), whereas no significant RNFL thinning was observed among MS patients without ON. However, there was a significant reduction in RNFL thickness among MS patients compared to healthy controls (76.79 versus 93.72 µm; P = .009), regardless of ON presence/absence. Conclusions: Axonal damage was seen in the optic nerves of Omani MS patients. Moreover, there was a significant reduction in RNFL thickness among MS patients with ON as the disease progressed; however, while there was evidence of RNFL thinning in MS patients without ON, this difference lacked statistical significance. Evaluation of RNFL thickness may represent a useful biomarker for monitoring disease progression in MS and its association with ON.

Background: Pandemic corona virus outbreak has global distribution and world health organization stated that there is a high risk of pandemic corona virus out spreading to other developing countries that can make health professionals serving in third world countries to fear for morbidity and mortality. Objectives: To assess level of perceived stress and associated factors among health care providers during corona virus outbreak in Ilu Aba Bora and Bunno Bedelle Zones, Oromia regional state South West Ethiopia 2020.Methods: Facility based cross sectional study design was conducted among 365 respondents. Perceived stress was assessed using perceived stress scale(PSS). The data was organized and processed by using epi info-7 and analyzed using SPSS version 21. Results: Prevalence of perceived stress was 57%. In multivariable logistic regression being married(AOR=4.6, 95% CI: 3.51;9.33), less than one year working experience (AOR= 2.57, 95%CI: 1.83-7.32) and having BSc degree and lower educational background in health related fields (AOR=3.8, 95%CI: 3.81; 7.03) was significantly associated with perceived stress among health care providers at p value of less than 0.05. Conclusion: Lower work experience, being married and lower educational background was significantly associated with perceived stress. Ministry of health in collaboration with ministry of education and other stakeholders should facilitate stress management skills inductive trainings to practitioners of newly recruited health care providers working in health care facilities.
Laser isotope separation of 176Lu through off-the-shelf lasers
Authors: Suryanarayana MV , Sankari Manda
Published: March 2021

We propose a novel and simple method for the laser isotope separation of 176Lu a precursor for the production of177Lu medical isotope. The physics of the laser-atom interaction has been studied through the dynamics of the atomic level populations using the density matrix formalism. It has been shown that a combination of cw excitation lasers and pulsed ionization laser can be used for the laser isotope separation of 176Lu. The optimum conditions for the efficient and selective separation of 176Lu have been derived by studying the time evolution of level population under laser excitation. It has also been shown that, it is possible to produce ~100% enriched 176Lu isotope at a rate of 5 mg / hour, which is higher than all previously reported methods so far. The isotope separation process proposed can be easily adopted using off-the-shelf lasers, for similar atomic systems.

Published: March 2021

Introduction: the emergence of the covid-19 pandemic has created major health risks to humanity as a whole, in turn, the world have been waiting for a solution to end this pandemic. This research aims to study the acceptance towards the covid-19 vaccine among the Lebanese population and investigate the factors affecting the descision towards the vaccine.Methods: In order to obtain a clear insight about the propensity of the Lebanese population to take the vaccine, a cross-sectional study was conducted, data collected through a questionnaire based on google forms and distributed among the population via social media platforms (Instagram, whatsapp, facebook, etc). the survey consisted of different types of questions and 1157 participants of different age groups respomnded to the survey.Results: The findings of this study reveals that the majority of the population (ovr 95%) know soemone who caught the corona virus. In addition (86.3%) of the population believe that the pandemic poses major health risks to the society in Lebanon. Moreover the respondants consider the source of the vaccine as a major determinant to whether or not they will take the vaccine, in fact (73.3%) trust the Pfizer-BioNtech vaccine. However, 77.1% of the sample worry that the vaccine will have side effects. in addition over 90% of the population was observed to be following the restrictions and measures implemnented to stop the spread of the virus.Conclusion: Within the limitations of this study, we can conclude that this study is the earliest attempt to assess the acceptance toward COVID-19 vaccination among the Lebanese population. The Lebanese population showed a moderately high acceptance rate for the vaccination, however, there is a notable percentage that needs to be directly addressed with any future awareness campaign which are the youth, and the people with low socioeconomic status.
Severe tumoral calcinosis in patient with chronic kidney disease
Authors: nassar kawtar , janani saadia
Published: March 2021

Tumoral calcinosis is a rare condition characterized by the deposition of calcium material in extra-articular soft tissues taking a tumoral form. It can be primary or secondary. The chronic kidney disease is among cause of metastatic calcifications but the extensive periarticular cyst-like calcium salt containing space-consuming lesions in the form of tumoral calcinosis is very rare. Different factors predispose the dialysis patient to calcium salt deposits. We report a case of 61 years-old-patient with chronic kidney disease under periodic hemodialysis due to hypertensive nephropathy who developed mechanical pain, evolving since three months, in the left hip, the upper extremity of the right leg and both shoulders with swelling and limited movement interfering with daily activity. The severe TC was diagnosed by the radiography and MRI requiring the modification of treatment strategy.

Background: In recent years, more and more studies revealed that liver fibrosis progression could happen at early stage in chronic hepatitis B (CHB) patients. However, there is no anti-fibrotic agent available at present in modern medicine.He-He-Shu-YangParticles (HHSYP) and Anluohuaxian Pills (AHP)are two commonly used Traditional Chinese Medicine (TCM) agents for liver fibrosis, but there is no data of them for early liver fibrosis(F1 or F2) in multicenter, randomized controlled trial. Therefore, the aim of this study is to evaluate efficacy and safety ofHHSYP plus AHP for early liver fibrosis in CHB patients. Methods/design: For the 72-week randomized controlled study, 480 CHB patients with early liver fibrosis are randomly assigned at a 2:1 ratio to two groups: the intervention group and the placebo group. The intervention group was treated with HHSYP plus AHP. The placebo group was treated with placebo of HHSYP and AHP. The primary end point is the histological change after 72-week treatment.Discussion: Although previous studies have confirmed the anti-fibrosis efficacy of HHSYP and AHP in CHB patients, the efficacy and safety of their combination treatment for early liver fibrosis is still not clear.Therefore, this will be the first multicenter randomized trial to prove the efficacy and safety of combination TCM treatment of HHSYP and AHP for early liver fibrosis, which will use histological changes as the primary end point. This will provide reliable data for the TCM combination treatment of early liver fibrosis and might give a new direction for further international studies on liver fibrosis.Ethics and dissemination: This study protocol was approved by the Ethics Committee of Guangdong Provincial Hospital of Chinese Medicine (BF2018-175-01) and all other participating centers (Project number2018ZX10725506-003).The study findings will be published in peer-reviewed journals and presented at the national and international conferences.

Relativity and View Effects
Authors: Fischli Bernard
Published: March 2021

Relativity has been based on the implicit assumption that electromagnetism would exclusively describe interactions. Relativistic view effects are included as well, and they act with no force and no energy exchanges. The Ehrenfest paradox is solved. View effects specific to each point of view are the solution. The calculation of the deflection of light by the sun explains in detail why the deflection angle must be almost double the value obtained with Newton’s laws. The compatibility of General Relativity with the new interpretation is discussed. View effects cannot impact total energy. An object has no speed limit due to relativity but can be limited due to other causes. Inertial behavior is examined. Inertial masses are redundant, but this does not introduce gravitation to General Relativity.
The bees of the genus Hylaeus Fabricius, 1793 of Turkey, with keys to the subgenera and species (Hymenoptera: Anthophila, Colletidae)
Authors: Özbek Hikmet , Dathe Holger H.
Published: March 2021

The paper presents data of around 4000 previously unpublished specimens, collected in various parts of the country during the last decades. With literature sources, a total of 86 species of the genus Hylaeus Fabricius, 1793 from 10 subgenera are compiled for Turkey. New for Turkey are 11 species: Hylaeus (Dentigera) kahri Förster, 1871, H. (Dentigera) pallidicornis Morawitz, 1876, H. (Hylaeus) deceptorius (Benoist, 1959), H. (Hylaeus) gracilicornis (Morawitz, 1867), H. (Hylaeus) paulus Bridwell, 1919, H. (Hylaeus) trisignatus Morawitz, 1876, H. (Nesoprosopis) pectoralis Förster, 1871, H. (Prosopis) incongruus Förster, 1871, H. (Prosopis) trinotatus (Pérez, 1896), H. (Prosopis) variolaris Morawitz, 1876 and H. (Spatulariella) sulphuripes (Gribodo, 1894). No new specimens could be found of 13 species which had been detected formerly. Our knowledge on the distribution of numerous species is greatly expanded. The characteristics of distribution are defined for the individual species. For example, H. meridionalis is the most widespread with records from 46 provinces covering all geographical regions of the country, while many other species are only known from one province, sometimes from a single record. The eastern part of Turkey, in particular the province of Hakkâri, proved to be an important centre of diversity for Hylaeus species. For a number of species the valid names had to be revised. Distribution maps are presented for the newly recorded and rare species. Frequently visited plant species are mentioned. Keys to the subgenera and species of Turkish Hylaeus are provided.

All species described by Warncke in 1981 and 1992 from Turkey in the genus Prosopis F. have not yet been revised and formally combined with the valid genus name Hylaeus F. There are however a number of online checklists, which have already registered most of these names under Hylaeus. Representatives of these checklists were checked here: The World Bee Checklist, integrated into the ITIS database (ITIS 2020) and Discover Life (Ascher & Pickering 2019).

Authors: Vani B R , N Sandhyalakshmi B , Sajjan Netra M , C Panduranga , B Deepak Kumar , V Srinivasamurthy
Published: March 2021

Background: NHL are heterogeneous group of hematolymphoid malignancy occurring in nodal and extra nodal sites. Extra nodal lymphoma (ENL) is distinct from nodal lymphomas due to varied anatomical location, morphological diversity.

Methods: A retrospective observational study was conducted in the department of pathology from January 2011 till December 2019. Clinical details and other investigations were recorded. Gross morphological features were noted. Slides are reviewed microscopically and blocks were subjected to IHC for further typing cases were selected as per Dawson et al criteria.

Result: During study period, ENL constituted 25 cases (29.4%) of the 85 cases of all NHL. Age range is 05 to 63 years with a mean age of 42.5 years. Male to female ratio is 2.2 :1.Head and neck is the most common site of ENHL constituting 19 cases(76%), next commonest location is in the GIT with 3 cases (12%). We had one each case of ENHL in testis, breast and spine (4% each). On IHC, 92% cases (23 cases) exhibited   B cell phenotype and the remaining 08 % (02 cases) were of T cell phenotype.

Conclusion: Lymphomas in the extra nodal sites are rare but has the propensity to occur in any anatomic site. Hence a differential of lymphoma to be considered in extra nodal site. Histology with IHC enables to differentiate from poorly differentiated carcinoma as the treatment modalities and prognosis varies.
Monomorfismo sexual de tamaño en el ganado Barroso-Salmeco de Guatemala
Authors: Jáuregui Raúl , Parés-Casanova P. M.
Published: March 2021

El dimorfismo sexual de tamaño (SSD por sus siglas en inglés) es un fenómeno ampliamente distribuido en los animales. Sin embargo, sigue siendo enigmático en cuanto a sus causas y a sus relaciones alométricas con el tamaño corporal (hipótesis de Rensch). A fin de contribuir a un mejor conocimiento de la raza bovina Barroso-Salmeco, de Guatemala, en esta investigación se analizó el SSD de 49 hembras y 5 toros mayores de 3 años, a partir de 23 variables morfoestructurales lineales y el peso vivo. Las diferencias estadísticas entre las variables para cada sexo permitieron detectar una ausencia de SSD, siendo únicamente el grueso de cañas la variable que se manifestó diferente entre sexos. Los resultados del análisis del dimorfismo sexual descartan que se presente en esta raza dimorfismo sexual en tamaño sesgado hacia los machos, y apuntan hacia un monoformismo sexual.

Published: March 2021

Las enfermedades producidas por virus como sida y leucemia son altamente prevalentes en felinos domésticos, debido a su facilidad de transmisión, presentan signos clínicos similares a otras infecciones que pueden generar dificultades en el diagnóstico, por lo tanto, se deben analizar mediante pruebas de laboratorio; los exámenes disponibles en la actualidad presentan algunas desventajas, por ello se estandarizó una PCR múltiple en tiempo real con sondas Taqman que fue diseñada para detección de infección con el virus de inmunodeficiencia felina (VIF), el virus de leucemia felina (VLFe) o mixtas. Se calculó la sensibilidad (0,53/0,26) y la especificidad (0,46/0,74) para leucemia y sida respectivamente con la metodología de Broemeling que considera que la prueba de referencia contra la cual se compara no es un referente verdadero (Gold standard), según estos resultados se concluye que es necesario aumentar el tamaño de muestra; sin embargo, la PCR múltiple es una metodología muy sensible, fue validada de forma in silico y presentó resultados congruentes al realizarla In vivo.

Published: March 2021

Vocabulary acquisition is the premise of learning language. In English learning, college students always feel perplexed and painful on acquiring English vocabulary. Therefore, this paper aims to analyze and reveal negative factors in English vocabulary acquisition of college students and put forward some countermeasures. Compared with previous studies, this paper comprehensively analyzes most of negative factors on English vocabulary acquisition and according to collected data, more concrete and practical measures are put forward to help college students acquire English vocabulary. Interviews and questionnaires are conducted in turn. Interviews with college students and teachers shows there are many factors that have an negative impact on vocabulary acquisition such as the influence of Chinese and culture, individual motivation, learning habits and teaching model. Questionnaire shows the difficulties and learning habits most students had as well as English teaching model they desire. Through questionnaire, it is found that low motivation is the most influential factor and there is a relationship between students’ grade and their motivation. At the end of this paper, some countermeasures are proposed to help students learn vocabulary more effectively.

Las palabras y los hechos. Sobre algunos textos de Ida Vitale y sus metamorfosis
Authors: Rocca Pablo
Published: March 2021

Antes de su exilio en México en 1974, durante tres exactas décadas Ida Vitale (Montevideo, 1923) publicó un breve conjunto de poemas. Algunos en revistas o antologías. La presión de lo cotidiano (crisis de toda clase, el peso de la Revolución cubana, etc.) gravitó, a veces, sobre su modalidad de escritura. Sin embargo, sus poemas resistieron al coloquialismo triunfante y la identificación de los hechos con las palabras. Vitale dejó caer varias de esas piezas, muchas las retomó con firmes correcciones. Este trabajo se propone indagar ciertos casos, algunos no compilados en volumen, incluso ahora que, a consecuencia de sus múltiples premios, se cuenta con ediciones más amplias de su obra poética en verso y en prosa. Sobre estas últimas, combinando una lectura filológica, histórica y cultural, se busca contribuir con nuevas piezas y posibilidades de lectura.
Interference as an information-theoretic game
Authors: Horvat Sebastian , Dakić Borivoje
Published: March 2021

The double slit experiment provides a clear demarcation between classical and quantum theory, while multi-slit experiments demarcate quantum and higher-order interference theories. In this work we show that these experiments pertain to a broader class of processes, which can be formulated as information-processing tasks, providing a clear cut between classical, quantum and higher-order theories. The tasks involve two parties and communication between them with the goal of winning certain parity games. We show that the order of interference is in one-to-one correspondence with the parity order of these games. Furthermore, we prove the order of interference to be additive under composition of systems both in classical and quantum theory. The latter result can be used as a (semi)device-independent witness of the number of particles in the quantum setting. Finally, we extend our game formulation within the generalized probabilistic framework and prove that tomographic locality implies the additivity of the order of interference under composition. These results shed light on the operational meaning of the order of interference and can be important for the identification of the information-theoretic principles behind second-order interference in quantum theory.

Tren Jarak Kelahiran Pendek Pada Pengguna Kontrasepsi di Indonesia 2002 – 2017 (Analisis Data Survei Demografi dan Kesehatan)
Authors: Fitri Adelina
Published: March 2021

Jarak kelahiran dapat diartikan sebagai jarak antara terjadinya suatu penghentian kehamilan (lahir hidup atau mati) dengan terjadinya kelahiran berikutnya. Jarak kelahiran yang pendek didefinisikan jika kelahiran terjadi kurang dari 24 bulan setelah kelahiran sebelumnya. Ibu yang melahirkan kembali dalam waktu singkat tentunya memiliki tingkat kesuburan yang sangat baik. Salah satu cara yang dapat dilakukan untuk mencegah terjadinya jarak kelahiran pendek adalah dengan menggunakan kontrasepsi. Tujuan penelitian ini untuk melihat tren jarak kelahiran pendek < 24 bulan pada pengguna kontrasepsi di Indonesia. Penelitian menggunakan data Survei Demografi Kesehatan Indonesia 2002 – 2017 dengan desain studi cross sectional. Jumlah ibu yang menjadi sampel setelah diterapkan kriteria inklusi dan eksklusi sebanyak 9644 (2002), 10470 (2007), 10162 (2012) dan 10854 (2017). Untuk tren persentase jarak kelahiran pendek (< 24 bulan) pada pengguna kontrasepsi di Indonesia mengalami peningkatan 2002 – 2017 yaitu 61,07% (2012), 62,63% (2007), 65,27% (2012) dan 68,04% (2017). Penggunaan kontrasepsi belum cukup efisien untuk mencegah terjadinya jarak kelahiran pendek (< 24 bulan) di Indonesia.

Play: emotional regulation in classical music performance
Authors: Francisca Skoogh
Published: March 2021

Musicians examining performance anxiety within the context of their own regular concert performances, is a rare event in western classical music. The Western classical music culture, from conservatory to the professional life that follows, is tinged with disciplined practise, competitions, result-focused ambition and demands for perfection. There is little or no room to explore psychological issues connected to the profession, a silence that needs to be addressed. Classical musicians are highly dedicated to their vocation but they also suffer from more music performance anxiety (MPA) than musicians in other musical genres. This article gives examples on how musicians themselves can find new ways of emotionally regulate MPA by identifying performance values connected to the traditions and ceremonies of classical music. Built in values concerning performance can be defined and explored through experimental concert settings. Furthermore the article gives examples on how Artistic Research (AR) projects are designed to challenge the silenced artist in the traditional classical concert setting and how AR can contribute to the research field of MPA giving voice to the artist's thoughts. The experimental projects presented in this article describe how different interventions can help to regulate the artist's emotions and at the same time develop concert performance practice. One project connects neuroscientific findings to performance and the second one is based on the psychoanalytic concept of play.
Ultrahigh Capacity Retention of Li2ZrO3-Coated Ni-rich LNCM811 Cathode Material through Covalent Interfacial Engineering

Published: March 2021

Nickel-rich
LiNiCoMnO
(LNCM811) is a promising lithium-ion battery cathode material, whereas
the surface-sensitive issues (i.e., side reaction and oxygen loss)
occurring on LNCM811 particles significantly degrade their
electrochemical capacity retentions. A uniform
LiZrO coating layer can effectively
mitigate the problem by preventing these issues. Instead of the normally
used weak hydrogen-bonding interaction, we present a covalent
interfacial engineering for the uniform
LiZrO coating on
LiNiCoMnO
materials. Results indicate that the strong covalent interactions
between citric acid and
NiCoMn(OH)
precursor effectively promote the adsorption of ZrO
coating species on
NiCoMn(OH)
precursor, which is eventually converted to uniform
LiZrO coating layers of about 7 nm
after thermal annealing. The uniform
LiZrO coating endows LNCM811 cathode
materials with an exceptionally high capacity retention of 98.7% after
300 cycles at 1 C. This work shows the great potential of covalent
interfacial engineering for improving the electrochemical cycling
capability of Ni-rich lithium-ion battery cathode materials.

Ethyl levulinate, one of main derivatives of levulinic acid (LA), is of
significant potential as platform chemicals for bio-based materials. The
esterification of LA was generally carried out in a conventional batch
reactor or in a conventional reactive distillation column. However,
traditional methods are hard to deal with equilibrium limited reactions
and azeotropic issues. Therefore, the reactive-vapor
permeation-distillation (R-VP-D) process, which integrated reaction,
distillation and membrane dehydration into one single unit, is proposed
in this paper and validated in the pilot-scale experiments. A
comparative study is made between a pilot-scale RD column with and
without vapor permeation membrane module. Owing to the water-selective
membrane and the ingenious design of related apparatuses, the R-VP-D
process reveal a superiority in LA conversion of 21.9% maximum higher
than RD without VP process and removing of product water about 53.6%
from VP module, which indicates its promising industrial application in
process intensification field.

Authors: Kaczmarek Emilia
Published: March 2021

Pharmaceutical industry and drugs advertisement is sometimes accused of
“creating diseases”. This article assesses and describes the role of
that industry in fostering medicalization. First, the notions of
medicalization and pharmaceuticalization are defined. Then, the problem
of distinguishing between harmful overmedicalization and well-founded
medicalization is presented. Next, the phenomenon of disease mongering
is explained and illustrated by the case analysis of medicalizing pain
and suffering in three contexts: 1) the general idea of medicalizing
physical pain, 2) the medicalization of grief, and 3) disease mongering
of pseudoaddiction - a condition promoted in order to increase the
demand for opioid pain relievers.

Authors: motallebi mohammad , Ghassemi Hassan
Published: March 2021

In this paper, with the purpose of improving the mechanical behavior of
DeepCwind semi-submersible floating offshore wind turbine (FOWT)
platform mooring lines, nonlinear catenary cables of platform are
divided into multi-segments and intermediate buoy. The mathematical
formulations of the dynamic equation acted on the cable with buoys are
described. Present study is employed to the OC4-DeepCwind
semi-submersible FOWT platform. It is designed for 200-meter water depth
with mooring lines consist of three catenary steel chain cables that
have an angle of 120 degrees to each other. The dynamic response of
multi-segment catenary mooring line with different buoys radiuses and
different positions along the cables were investigated. The full-scale
platform was modeled in ANSYS-AQWA software and the simulations are
performed in harsh offshore. The tension, strain, anchor uplift, cable
uplift for different buoy radiuses and its position along cable are
presented and discussed. Moreover, platform motions at three directions
(surge, heave and pitch) are also analyzed. It is concluded that by
correct selection of the buoy volume and position along cable, the
tension of the cable may be reduced up to 45%. By incorrect selection
of the buoy, the results will cause adverse effects.
