Published: February 2022

Cat’s whiskers or the ‘misai kucing’ is an herbal plant native to the Southeast Asian region. The polyphenol enriched leaf extract contains numerous medicinal properties of major pharmaceutical interest. In this study, selected cat’s whiskers polyphenols were screened computationally to predict the minimum binding affinities with severe acute respiratory syndrome coronavirus (SARS-CoV) molecular targets. Molecular docking analysis showed that the caffeic acid derivatives and polymethoxylated flavonoids from cat’s whiskers bound stably to the binding pocket regions of SARS-CoV molecular targets at – 4.2 to – 7.1 kcal/mol. Furthermore, these cat’s whiskers polyphenol-bound SARS-CoV complexes were held fairly strongly by hydrophobic interactions, hydrogen bonds, and electrostatic interactions at various extents.

Authors: Penserga Grace G. , Penserga Ester G.
Published: February 2022

Objective. The study aimed to determine patient-related factors associated with inadequate treatment response of patients with rheumatoid arthritis (RA) to methotrexate (MTX).

Methodology. We reviewed the medical records of patients with RA seen at the rheumatology outpatient clinic of Philippine General Hospital; dichotomized into those with adequate and inadequate treatment response to MTX. Clinical data including age, gender, comorbidities, smoking status, tender joint counts, disease activity score-28 (DAS28), and rheumatoid factor (RF) positivity were compared between the two groups. We used univariate binary logistic regression to determine whether these clinical factors were significantly associated with inadequate treatment response.

Results. Majority (47/77 or 61%) of patients have inadequate treatment response to MTX. There were no significant differences between the two study groups in terms of age, tender joint count, DAS28, sex, smoking status and RF positivity. These factors also failed to show significant association with inadequate treatment response.

Conclusion. Age, sex, smoking status, duration of disease, initial DAS28, RF positivity and tender joint counts are not significantly associated with inadequate treatment response. A larger sample size is needed to estimate the prevalence of inadequate treatment response to MTX and derive a predictive model for treatment response.

Published: February 2022

Objectives. 1) To translate and cross-culturally adapt the Knee Injury and Osteoarthritis Outcome Score (KOOS) into Filipino; 2) To validate the Filipino translation of KOOS using the Filipino Short-Form 36 Health Survey (SF-36) among patients with knee osteoarthritis (kOA) at a tertiary hospital.

Methodology. A Filipino version of the KOOS was translated and cross-culturally adapted from the original English version and validated following standard guidelines. Adult Fiipino patients with knee osteoarthritis at the University of the Phiippines-Philippine General Hospital were asked to complete identical questionnaires containing the Filipino KOOS and Filipino SF-36, with re-test on the same patients after a median of 14 days. Reliability was assessed using Cronbach’s alpha and intraclass correlation coefficients (ICC); dimensionality using convergent and divergent construct validity.

Results. The Filipino translation of the KOOS was administered to 30 patients with knee OA (kOA). Cronbach's α across the Filipino KOOS domains ranged from 0.71 to 0.89 suggesting good internal consistency. The reproducibility of measurements of all KOOS subscales by ICC ranged from 0.97 to 1.0. For convergent construct validity, there was moderate correlation between KOOS ADL (0.38, p =0.03) and knee-related QoL (0.42, p=0.02) by SF-36 Physical Functioning (PF). A strong correlation (0.51, p=0.003) was observed between KOOS sports and recreation domain with SF-36 PF. For divergent construct validity, there was weak correlation between KOOS pain (0.015, p=0.93) and symptoms (0.15, p=0.42) with SF 36 Social Functioning.

Conclusion. The Filipino version of the KOOS is a valid and reliable instrument to measure the different aspects of disability affecting quality of life of Filipino patients with kOA.
Pre-service teacher preparation for early childhood education in Ghana: A review of literature
Authors: Osafo-Acquah Aaron
Published: February 2022

As a result of the continued interest in the expansion of early childhood education opportunities in Ghana, questions have arisen about how to prepare teachers for work in this context. This literature review explores the state of pre service teacher preparation for early childhood education in Ghana. Findings from the review show that Ghana faces a lot of challenges including lack of trained teachers, poor infrastructure, and poorly developed teaching and learning. The first formal declaration to address early childhood education in Ghana came in the form of the Gold Coast Colony Education Department schedule of 1930, which included a syllabus for infant classes as part of a primary schedule. The syllabus included instruction based on games, physical exercises, spoken English, singing, and arithmetic (McWilliam, H.O.A., & Kwamena-Po, M. A. (1975). After Ghana gained independence in 1957, the Education Act of 1961 was enacted to designate preschool as the responsibility of the Ministry of Education, and also declared compulsory basic education (Kindergarten- Middle school) as free for all children from age Four (4) to age Fifteen( 15). Four years later, the Nursery and Kindergarten Unit of the Ghana Education Service was created. The purpose of that unit was to develop preschools, nurseries, Kindergartens, as well as assist in the evaluation, control, and registration of these institutions. The idea of employing teaching staff who were trained teachers and professionals, led to the establishment of the National Nursery Teachers’ Training Centre in Accra in 1965 to train early childhood personnel (Morrison, 2002). By the year 1975, the Department of Social Welfare supervised 488 day care centres and the Ghana Education Service supervised 567 nursery schools and Kindergartens which enrolled 56,089 children. In an effort to regulate these early childhood centres and their programmes, the Department of Social Welfare established guidelines, which required centres to apply for permit and therefore register with the Department of Social Welfare. The Children’s Act of 1989 was therefore established and put into effect.

Nuevas herramientas para el diagnóstico del cáncer de vejiga
Authors: Paz Juan Fernando , Echeverria Fernando , García-Perdomo Herney Andrés
Published: February 2022

Abstract
Bladder cancer is the eleventh most common malignancy worldwide and carries high morbidity and mortality. For its diagnosis, multiple imaging tools such as CT urography and cystoscopy, which remain the gold standard to this day, have been used. A narrative review was performed in multiple databases (Medline, Scopus, ScienceDirect). Photodynamic diagnosis, as well as tomography bladder reconstruction for virtual cystoscopy, are diagnostic methods that have been introduced more recently. Likewise, contrast ultrasound and particularly bladder multiparametric MRI with the VI-RADS classification have been proposed as novel alternatives. The latter could end up changing the diagnostic paradigm, however, more studies are required to recommend their widespread use, which would still be limited by their availability.

Introdução: O câncer é sabidamente um importante problema de saúde pública, e o conhecimento epidemiológico desta doença, desde seus aspectos etiológicos até os fatores prognósticos envolvidos em cada tipo específico de neoplasia é de fundamental importância. Objetivo: analisar o perfil clínico e epidemiológico dos pacientes atendidos em um serviço de referência no sul do estado de Mato Grosso. Material e Métodos: Avaliou-se 1297 prontuários. Para descrição das variáveis utilizou-se distribuição de frequência e regressão logística simples e múltipla com variância robusta. Os resultados foram apresentados na forma de odds ratio bruta e ajustada. Todas as variáveis que apresentaram p < 0,20 no modelo simples foram incluídas no modelo de regressão múltiplo ajustado por faixa etária, estratificado por sexo. Utilizou-se o teste de Hosmer-Lemeshow para avaliação da qualidade de ajuste do modelo múltiplo. Em todas as análises utilizou-se o nível de significância para o Teste de Wald de 5%. Resultados: A partir dos dados disponíveis, verificou-se que a maioria dos pacientes eram do sexo masculino, idosos, pretos/pardos e casados ou tinham união estável. A maioria dos prontuários não possuía informações sobre estilo de vida, estado nutricional, história familiar e comorbidades. Dentre os pacientes cujos prontuários traziam dados do estado nutricional, a maioria estava com baixo peso ou com excesso de peso. Com relação à caracterização do tumor, os mais frequentes foram próstata, mama, ginecológicos e colorretal. Conclusão: Com base nos resultados obtidos, constatou-se que o perfil clínico epidemiológico é condizente com aquele relatado na literatura que contempla outras regiões do país. O conhecimento dessas características é necessário para implementar as estratégias de detecção precoce das neoplasias, os processos diagnósticos e ações de promoção de saúde.
Echoes of the Armenian Genocide in Folk Calendar
Authors:   Institute of Archaeology and Ethnography, National Academy of Sciences, Armenia, Sargsyan Armen
Published: February 2022

The transmission of the memory of the Armenian Genocide has been reflected not only in a number of types of Armenian folk epic-lyrical folklore, but also in various memoirs, one of which has been the folk calendar. In the latter case, the person directly or through the mediator allegedly presents the atrocities of the perpetrators of the Armenian Genocide. Calendar reflections on the transmission of the memory of Genocide realities are made through oral inquiries. Dialogical-interrogative structures expressed in these folk sayings come in various thematic manifestations: a. with a calendar description of birth dates, b. with the argument of the calendar time of marriage, c. with survey of the age of an eyewitness during the Genocide, reflecting the deportation/exile, d. pointing to the self-defense heroic battles, e. through episodes related to the heroes of the national liberation movement. The folk calendar is original, eloquent fragments of memory. They are presented through eyewitness-survivors’, their relatives’ or other persons’ accounts, as a unique historical and documentary material certifying the Armenian Genocide.

Published: February 2022

We have studied the Light Addressable Amperometric Sensor (LAAS) which is a two dimensional electrochemical sensor. In this study we report the LAAS that enables multiples samples measurement based on planer structure made by photolithography. We deposited SU-8 and platinum films on the LAAS device to form well array in order to keep individual sample solutions. The LAAS performs individual measurements by selecting each well using addressing light beam. The results showed that the observed current value depends on concentration of redox species from 10pM to 1 mM in 1 well. Therefore, we found that the proposed structure functions correctly, and expect efficiency improvement of processes such as drug discovery screening
Filter Design and Amplitude Shaping Methodologies for De-Noising Digital Hearing Aids
Authors: Kumari Prerna , Singh Deepak
Published: February 2022

Uses of the digital hearing aids have been increased in last decades due to heavy noise pollution. The efficiency of the hearing aids is challenging under the presence of highly noisier environments. Therefore, it is highly required to design an efficient de noising method capable of reducing the excessive amplitude present in environment. It is also desirable to design the compact tiny digital herring aids easy to wear. This paper is focused to preset the de-noising methodologies for speech enhancement in digital hearing aids. Various methodologies based on FIR and IIR filter design are presented and performance is evaluated. It is observed that for short term speech samples the amplitude shaping methods become challenging task due to significant amplitude reduction during de-noising. Thus paper presets the adaptive scaling method for amplitude enhancement. The overall goal of paper to design efficient methodology for digital hearing aids.

Published: February 2022

This work studied conventional regeneration of saturated activated carbon using muffle furnace. The activated carbon was prepared from brewer’s spent grain using carbonization and chemical activation with potassium hydroxide. It was saturated with methylene blue dye and regenerated using muffle furnace. Effect of 30% hydrogen peroxide (H202 ) as an oxidant in the regeneration process was studied. Adsorption – regeneration process was studied for six cycles. Regeneration condition was optimized using central composite design (CCD). Effect of regeneration temperature and time on the adsorptive capacity of regenerated carbon was studied for one cycle. Adsorptive capacity and regeneration efficiency were found to decrease with increase in the number of cycles. 30% H202 had a tremendous effect on the adsorptive capacity of the regenerated carbon. The adsorptive capacity increased as the temperature grew from 200°C to 500°C, but dropped after being raised to 6,000°C. Adsorptive capacity increased from 10 minutes to 30 minutes, but declined to 50 minutes. The Quadratic model was used to regenerate a long network of electronics devices. In this experiment, the parameters were exactly what were required for optimal adsorption: temperature of 537.76 degrees Celsius, time of 29.34 minutes, and an initial dye concentration of 100mg/L with estimated adsorptive capacity of 54.2827mg/L. This was an extremely small mistake of 0.02 percent following validation.

Functional gastrointestinal disorders (FGIDs) in children and adolescents are one of the most common pathologies of the digestive tract. The aim of the study was to study the structure of the colon microbiota in obese adolescents and to establish its relationship with the clinical manifestations of the disease FGIDs. The study included 20 adolescents aged 11-17 years. The main group included 13 adolescents with a clinically confirmed diagnosis of obesity (the standard deviation of the body mass index (SDS BMI) is more than 2,0) in combination with FGIDs. The control group consisted of 7 adolescents with normal body weight and no abdominal complaints (SDS BMI=0,66). Clinical symptoms from the bowel re diagnosed on the basis of the Rome IV. The consistency of feces was evaluated using the Bristol Stool Form Scale. The study of biological material was carried out by standard bacteriological methods. It is shown that in adolescents with obesity and FGIDs, there is a decrease in the concentration of representatives of bifidoflora, an increase in the microbial density of Escherichia coli with altered properties and an excessive growth of potentially pathogenic enterobacteria. It is established that the presence of conditionally pathogenic bacteria is sem. Enterobacteriaceae is associated with abdominal pain during defecation. In obese adolescents in the group with unformed stools, Clostridium spp was recorded as part of the intestinal microbiota.

Investigating the impact of Saharan dust aerosols on analyses and forecasts of African easterly waves by constraining aerosol effects in radiance data assimilation

Abstract. This study incorporates aerosol effects into satellite radiance calculations within the Global Data Assimilation System (GDAS) to investigate its impact on the analyses and forecasts of African easterly waves (AEWs). Analysis fields from the aerosol-aware assimilation experiment were compared to an aerosol-blind control during August 2017. The results showed that the aerosol-aware assimilation warmed the Saharan boundary layer, accelerated the African easterly jet, and modified the time-averaged AEWs by enhancing the northern track and reducing the southern track. The changes to the tracks are qualitatively consistent with arguments of baroclinic and barotropic instability. During the time period, we also examined two AEWs that developed hurricanes Gert and Harvey over the Atlantic but were structurally different over Africa; the AEW for Gert consisted of a southern vortex, while the AEW for Harvey consisted of a northern and southern vortex. Analysis differences of the cases showed stronger vorticity changes for the AEW that developed Harvey, which we attribute to the aerosol-aware assimilation capturing the radiative effects of a large-scale Saharan dust plume interacting with the northern vortex of the wave. Subsequent forecasts for the AEW cases using the Global Forecast System (GFS, v14) showed that the aerosol-aware assimilation reduced errors in the downstream vorticity structure for the AEW that developed Harvey; neutral improvement was found for the AEW that developed Gert. Thus, aerosol-affected radiances in the assimilation system have the ability to account for dust radiative effects on the analyzed AEWs, which, in turn, can improve the forecasting of AEWs downstream.

Abstract. The COVID-19 pandemic created an extreme natural experiment in
which sudden changes in human behavior and economic activity resulted in
significant declines in nitrogen oxide (NOx) emissions, immediately after
strict lockdowns were imposed. Here we examined the impact of multiple waves
and response phases of the pandemic on nitrogen dioxide (NO2) dynamics
and the role of meteorology in shaping relative contributions from different
emission sectors to NO2 pollution in post-pandemic New York City. Long
term (> 3.5 years), high frequency measurements from a network of
ground-based Pandora spectrometers were combined with TROPOMI satellite
retrievals, meteorological data, mobility trends, and atmospheric transport
model simulations to quantify changes in NO2 across the New York
metropolitan area. The stringent lockdown measures after the first pandemic
wave resulted in a decline in top-down NOx emissions by approx. 30 % on
top of long-term trends, in agreement with sector-specific changes in NOx
emissions. Ground-based measurements showed a sudden drop in total column
NO2 in spring 2020, by up to 36 % in Manhattan and 19 %–29 % in
Queens, New Jersey (NJ), and Connecticut (CT), and a clear weakening (by 16 %) of the
typical weekly NO2 cycle. Extending our analysis to more than a year
after the initial lockdown captured a gradual recovery in NO2 across
the NY/NJ/CT tri-state area in summer and fall 2020, as social restrictions
eased, followed by a second decline in NO2 coincident with the second
wave of the pandemic and resurgence of lockdown measures in winter 2021.
Meteorology was not found to have a strong NO2 biassing effect in New
York City after the first pandemic wave. Winds, however, were favorable for
low NO2 conditions in Manhattan during the second wave of the pandemic,
resulting in larger column NO2 declines than expected based on changes
in transportation emissions alone. Meteorology played a key role in shaping
the relative contributions from different emission sectors to NO2
pollution in the city, with low-speed (< 5 m s−1) SW-SE winds
enhancing contributions from the high-emitting power-generation sector in NJ
and Queens and driving particularly high NO2 pollution episodes in
Manhattan, even during – and despite – the stringent early lockdowns. These
results have important implications for air quality management in New York
City, and highlight the value of high resolution NO2 measurements in
assessing the effects of rapid meteorological changes on air quality
conditions and the effectiveness of sector-specific NOx emission control
strategies.
Towards improving short-term sea ice predictability using deformation observations

Published: February 2022

Abstract. Short-term sea ice predictability is challenging due to the lack of constraints on ice deformation features (open leads and ridges) at kilometre scale. Deformation observations capture these small-scale features and have the potential to improve the predictability. A new method for assimilation of satellite-derived sea ice deformation into the neXt generation Sea Ice Model (neXtSIM) is presented. Ice deformation provided by the Copernicus Marine Environmental Monitoring Service is computed from sea ice drift derived from Synthetic Aperture Radar at a spatio-temporal resolution of 10 km and 24 hours. We show that high values of ice deformation can be interpreted as reduced ice concentration and increased ice damage – scalar variables of neXtSIM. The proof-of-concept assimilation scheme uses a data nudging approach and deterministic forecasting with one member. Assimilation and forecasting experiments are run on example observations from January 2021 and show improvement of neXtSIM skills to predict sea ice deformation in 3–5 days horizon. It is demonstrated that neXtSIM is also capable of extrapolating the assimilated information in space — gaps in spatially discontinuous satellite observations of deformation are filled with a realistic pattern of ice cracks, confirmed by later satellite observations. The experiments also indicate that reduction in sea ice concentration plays a bigger role in improving ice deformation forecast on synoptic scales. Limitations and usefulness of the proposed assimilation approach are discussed in a context of ensemble forecasts. Pathways to estimate intrinsic predictability of sea ice deformation are proposed.
