Experimental Characterization of a Rotor to Dynamic Collective Pitch Inputs in Hover
Authors: Mortimer Patrick , Sirohi Jayant
Published: July 2024

Experiments were performed on a two-meter diameter, four-bladed rotor to extract the coefficients of a dynamic inflow model. The frequency response of rotor induced velocity to rotor thrust was found by introducing stepped-sine collective pitch inputs at frequencies of 0.2 per revolution to 0.7 per revolution, where the rotor rotational frequency was 14 Hz. The induced velocity field was measured using phase-resolved, two-dimensional, three-component particle image velocimetry (PIV) over a large region of interest (0.84 m x 0.77 m) in a radial slice of the rotor flow field. The rotor thrust was measured using a hub-mounted load cell. Limited by the frame rate of the cameras, PIV was performed using an under-sampling technique in which one image pair was captured during each rotor revolution, and the time history was recreated from the phase-resolved measurements. The thrust amplitude was found to increase with input frequency, reaching 27.4% of the steady thrust at the highest input frequency. The induced velocity amplitude followed the opposite trend, decreasing to 2.0% of the steady value at the highest input frequency. Dynamic inflow states were extracted and fit to a first-order transfer function. The gain and corner frequency of the transfer function were found to be K = 34.7 +/- 1.52 dB and b = 4.08+/-0.19 rad/s, respectively, which followed a similar trend to computational studies reported in the literature.

Authors: Donate-Correa Javier , Ferri Carla M. , Mora-Fernández Carmen , González-Luis Ainhoa , Navarro-González Juan F. , Pérez-Delgado Nayra
Published: July 2024

Background: Diabetic kidney disease (DKD) is associated with a higher risk of cardiovascular disease (CVD). Pentoxifylline (PTF), a nonselective phosphodiesterase inhibitor with anti-inflammatory, antiproliferative, and antifibrotic actions, has demonstrated renal benefits in both clinical trials and meta-analyses. The present work aimed to study the effects of PTF on the progression of subclinical atherosclerosis (SA) in a population of patients with diabetes and moderate to severe chronic kidney disease (CKD).
Methods: In this open-label, randomized controlled, single-center pilot study the evolution of carotid intima-media thickness (CIMT) and ankle-brachial index (ABI) were determined in 102 patients with type 2 diabetes mellitus and CKD assigned to PTF, aspirin or control groups during 18 months. We also determined the variations in the levels of inflammatory markers and Klotho (KL), a protein involved in maintaining cardiovascular health, and their relationship with the progression of SA.
Results: Patients treated with PTF presented a better evolution of CIMT, increased Klotho levels and reduced the inflammatory state. The progression of CIMT values was inversely related to variations in KL both in serum and mRNA expression levels in peripheral blood cells (PBCs). Multiple regression analysis demonstrated that PTF treatment and variations in mRNA KL expression in PBCs, together with changes in HDL, were significant determinants for the progression of CIMT (adjusted R2= 0.25, P < 0.001) independently of traditional risk factors. Moreover, both variables constituted protective factors against a worst progression of CIMT [OR: 0.105 (P = 0.001) and 0.001 (P = 0.005), respectively].
Conclusions: PTF reduced SA progression assessed by CIMT variation, a beneficial effect related to KL gene expression in PBCs.
Trial registration: The study protocol code is PTF-AA-TR-2009 and the trial was registered on the European Union Drug Regulating Authorities Clinical Trials (EudraCT #2009–016595– 77). The validation date was 2010-03-09.

Even after 75 years of Indias independence, the country still suffers from social inequality to some extent, especially the segregation or backwardness among different castes. Caste backwardness is still present in the country. It is a fact that living in a backward state, they are often unable to experience the benefits of the countrys progress. The people belonging to the tribal groups cling to their traditional culture and still live in geographically remote areas. India adopted decentralised planning through which local governments obtain more decision-making powers and can address local needs. But even now its benefits were not completely trickle down to many of the marginalized sections living in the society. This study aims to examine financial assistance provided through Panchayat institutions for the development of Tribal population. Different kinds of funds were distributed through Panchayath Institutions but flow of fund was not maintaining a proportionate increase over the years.

India is currently known as the global agricultural power house. Agriculture provides food, fodder, employment opportunities and business. Panchayats and Municipalities in a state establish Krishibhavans to improve the production and productivity of crops through implementation of various government schemes. Each Krishi bhavan consists of agriculture officers and agriculture employees. In each state Krishi bhavans was established to support and endure theactive functioning of agriculture department at the grassroots level. Krishibhavan provideshighly productive modern variety seeds, plant protection devices and formulate programs and policies relating to credit to farmers. This department provides subsidies and provisions of insurance to reduce risk in the cultivation. The objective of the present study was to determine the factors which helps to channelize the agricultural information for farming community and also compare the services provided by Krishi bhavans at panchayath and municipality. The study has revealed that most of the sample respondents are unaware of the facilities of Krishi bhavan. Krishibhavans at Municipality give better benefits to farmers compared to panchayath Krishi bhavan.

Jelly candies are colorful, delicious, and loved by children. Mackerel skin gelatin has a good nutritional potential to increase the protein content in jelly candy. The present study tested consumer acceptance, proximate value, and quality of gelatin jelly candy fortified with eight different natural flavorings: honey, date juice, olive oil, soy milk, goat’s milk, grape juice, avocado, and pumpkin.
Gelatin was extracted from mackerel (Scomberomorus commersonii) skin. The quality assessment involved tests on the water, ash, fat, and protein contents, as well as bacterial contamination. The sensory evaluation involved a hedonic test with 10 panelists, who found all samples acceptable in appearance, smell, flavor, and texture.
The average score for each criterium was 7.00 out of 9.00. The sample with soy milk proved to have the most optimal formulation: water (9.76 ± 0.70%), ash (0.21 ± 0.02%), protein (16.20 ± 0.37%), fat (2.32 ± 0.50%), carbohydrate (51.61 ± 0.80%), reducing sugar (0.14 ± 0.01%). All samples were free from Salmonella sp. and Escherichia coli, with a total plate count of 1×102 colonies per 1 g.
The jelly candy with mackerel skin gelatin was high in protein, had a favorable sensory profile, and met the Indonesia National Standard for this type of food products.

Authors: Sverdlova Olga , Podshivalova Elizaveta , Sharova Natalya , Belova Daria
Published: July 2024

Rapeseed oil production is very active in Russia. Its main by-product is cake: its chemical composition and availability make it an excellent source of nutrients in microbial cultivation to be used as biologically active compounds or as part of functional products. The research objective was to study the native microbiota of rapeseed cake under conditions of high humidity, as well as to describe the morphology of isolated microorganisms and determine their genera by NGS sequencing.
The study featured rapeseed cake and microbial colonies isolated after 2, 5, 7, and 9 days of fermentation. The microbial isolates were obtained by the method of surface and deep cultivation on solid and liquid nutrient media, respectively. The metagenomic analysis of the microbial taxonomy involved sequencing on the Illumina platform.
The experiment revealed 16 types of colonies with different morphology. Colonies with morphology 1, 3, 8, 12, and 13 were predominant for all fermentation periods, which means that they grew as isolates during the liquid-phase fermentation. The metagenomic analysis revealed at least 28 genera of bacteria in the rapeseed cake suspensions. The highest percentage belonged to Weisella (≤ 45.8% on day 2), Acinetobacter (≤ 40.6% on day 7), Lactobacillus (≤ 15.7% on day 5), Leuconostoc (≤ 15.1% on day 7), Enterococcus (≤ 14.6% on day 5), and Paenibacillus (≤ 16.3% on day 9).
The obtained isolates could be of interest as industrial producers of useful metabolites, e.g., enzymes, pigments, organic acids, etc. Further research will identify the microbial species, their useful properties, and optimal cultivation conditions.

Published: July 2024

Sous vide technology came to Russia in the early 2000s. Its quality standards require a multidimensional comprehensive study to develop theoretical and methodological foundations. The research featured the effect of various Sous vide modes on beef quality based on histological analysis and sensory assessment.
The review of best practices in this sphere included publications registered in Scopus, Web of Science, and eLIBRARY.RU. Beef from sacral part underwent Sous vide processing at two modes, i.e., 57 and 64°C for 24 h and 80°C for 12 h. The samples obtained were subjected to histological analysis and sensory assessment.
The histology showed that the cooking process at 100°C and the Sous vide modes at 57, 64, and 80°C increased the intercellular space and dissolved the connective tissue. Higher temperature modes led to more pronounced shrinking and deformation of muscle fibers. Under the Sous vide conditions, fibrous structures demonstrated the most severe destruction after 12 h at 80°C. As the destruction of muscle fibers increased, more nuclei entered intercellular space. Moreover, perimysium and sarcolemma demonstrated signs of granulation between muscle fiber bundles. The Sous vide samples received the best score for juiciness and tenderness.
The research revealed a certain contradiction between the growing degree of fibrous destruction caused by thermal treatment and the improving consistency index for juiciness and tenderness. The authors consider it necessary to investigate the matter further and invite specialists to submit their ideas.

The legislation of the Russian Federation stipulates the necessity for accreditation within the national system that en-compasses organizations engaged by control (surveillance) bodies to accomplish inspections. Activities performed by inspection bodies have strategic importance and provide necessary support for surveillance over implementation of national development projects. It is especially relevant to provide uninterrupted functioning of accredited inspection bodies. Contemporary conditions require improvement of the existing legal and organizational approaches used by federal budgetary institutions in their activities as well as developing and implementing new ones. Statistical data on the research object of the present study and relevant mathematical models are non-existent; given that, we applied an expert approach to risk identification using the Delphi method and expert judgment. The aim of this study was to analyze and assess risks in activities performed by an accredited inspection body and suggest ways to minimize them. Two groups took part in the study. The first one included experts (18 technical directors of three inspection bodies); the second group was made of analysts. The most competent specialists in the analyzed field of activity where risks would be identified were selected as experts. Their functional duties covered responsibility for risks associated with activities of an inspection body as well as for responses to them. To obtain ideas of analyzed risks, we used a questionnaire to collect experts’ answers and to distribute them into specific categorize for further analysis. A risk level was identified by using the risk analysis diagram. Any response measures were taken relying on this level. We created a register of risk levels and responses to them. A high risk was identified in activities performed by an inspection body as regards external influence of new changes in the legislation. Reformation of the accreditation system for organizations operating in the sphere of providing sanitary-epidemiological welfare may be a potential solution to the existing problem.
COVID-19 pandemic: the role of risk factors related to urban space (Analytical review)

Comfortable urban environment plays a key role in protecting health of people residing in large urban settlements. At the same time, urban space has some peculiarities including high population and building density, imperfect traffic infrastructure, irrational planning decisions, elevated levels of ambient air pollution, heat islands and lack of urban green spaces. All these features of any urban space are significant health risk factors able to facilitate spread of respiratory diseases. This was the most evident during the COVID-19 pandemic. The analytical review examines the results of studies focusing on impacts exerted by these unfavorable urban conditions on COVID-19 infection, incidence, hospitalization and mortality in cities across the globe. Influence of elevated population density on COVID-19 infection is shown to be ambiguous as compared to other risk factors. More reliable data are available on the impact of air pollutants, especially PM, on incidence and mortality rates from the infectious disease in question. Also, the COVID-19 virus and abnormally high temperatures were shown to produce combined effects on mental health during the pandemic. To reduce levels of infection in urban population, a suggestion is to further develop urban infrastructure providing people with retail and other necessary facilities within a walking distance (15 minutes). An important conclusion has been made by experts on elevated risks of infection in dense foot traffic as compared to public buildings. Therefore, it is important to improve communications about the necessity of social distancing. Urban development that aims to reduce infection with respiratory diseases should involve better street aeration. The results of these studies in various cities across the globe gave grounds for making management decisions on providing better mobility in suburban areas in a more comfortable natural environment, developing green areas in cities, and reducing negative effects of the warming climate on heat islands and elevated levels of ambient air pollution. Large open green spaces are the most effective in this respect.
“Do querer que há, e do que não há em mim”

O artigo tem como objetivo problematizar a constituição de espaços de memória em quatro escolas centenárias do Rio Grande do Sul e analisar a atuação das responsáveis por esses lugares. O estudo, inscrito no campo da História da Educação, toma como referência os conceitos de patrimônio histórico-educativo e guardiãs de memória. Metodologicamente, foram visitados os museus e memoriais das instituições e entrevistadas as professoras que lá trabalham. Constatou-se que esses lugares, criados para preservar a memória, narram uma história edificante do passado institucional. Ao mesmo tempo, observa-se que a potência desses espaços depende muito da disposição e entrega dessas mulheres. Conclui-se que há um descompasso entre a dedicação das professoras e os gestos de guardar das escolas, indicativo da importância de maiores investimentos na construção de políticas de memória, não apenas centradas em ações individuais, mas fomentem atividades coletivas mais fecundas, ampliando, assim, a força do conceito do patrimônio histórico-educativo.
Zaíta esqueceu de guardar os brinquedos – o percurso de balas pedidas: o diálogo entre a notícia e o conto literário
Authors: Araujo Wagner
Published: July 2024

Este artigo visa promover reflexões acerca dos elementos intertextuais que dialogam tematicamente e estabelecem influência na construção do projeto ficcional do conto “Zaíta esqueceu de guardar os brinquedos” da autora Conceição Evaristo, advindos do gênero notícia. Para tanto,  nos valemos da análise do conto em diálogo com a temática evidenciada nas notícias de jornais circunscritas aos eventos ocasionados por balas perdidas. Por meio de uma abordagem qualitativa e metodologia teórico-analítica-comparativa, objetiva-se propor um modelo de leitura acerca da relação intertextual entre a notícia e o conto literário, considerando seus aspectos convergentes (unidade, meio de veiculação de origem) e divergentes no que se refere à ordem, objetividade e linguagem usada no modo de retratar a realidade e discutir, por meio do diálogo entre os gêneros textuais, aspectos que mobilizaram uma escrita voltada ao universo infantil e de inocência no contexto violento da periferia.
Duas mulheres e uma experiência: a narrativa dualista de Chimamanda Adichie
Authors: Bezerra de Araújo Rosanne , De Araújo Cadó Júlio César , Costa Menezes da Rocha Maria Clara
Published: July 2024

Este artigo analisa o conto “Uma experiência privada”, de Chimamanda Adichie, ressaltando não somente a estética narrativa da autora, mas também as temáticas abordadas em seus enredos. O impasse entre religiões, culturas, países e etnias é um marco constante em suas histórias. No conto que elegemos para estudo, privilegiamos o encontro, a união e a ternura da experiência humana trocada entre as duas personagens. Em lugar de ressaltar a diferença, este estudo defende a reconciliação entre povos e culturas, como frisa a própria autora em suas ficções e ensaios. Seguimos o pensamento crítico de autores como Pascale Casanova, Frantz Fanon e Homi Bhabha que nos esclarecem sobre situações conflituosas e antagônicas na sociedade contemporânea. O resultado deste estudo aponta para uma possível mediação entre a identidade individual e o quadro geral da sociedade. De fato, o texto literário une o que a realidade social insiste em separar.

O artigo tem como objetivo analisar e problematizar a criação do Departamento de Documentação e Cultura e a sua importância para o desenvolvimento das políticas públicas voltadas para as construções de Bibliotecas Populares na cidade do Recife.  Em 1949, foi promulgada pelo presidente da Câmara Municipal do Recife e autorizada pelo prefeito Pelópídas Silveira a Lei n° 292, de 16 de abril, que instituía a criação de bibliotecas populares nos bairros da periferia da capital de Pernambuco. As políticas culturais e educacionais propiciadas pela efetivação da Lei impactaram as vidas daqueles que delas puderam ter acesso à leitura. Os benefícios trazidos por essas bibliotecas revelaram uma dimensão antes nunca vista no cenário cultural e educacional do Recife. As bibliotecas populares romperam com o imobilismo da Biblioteca Pública e conseguiram levar a leitura à população mais distante do centro, além disso, proporcionaram o crescimento intelectual do povo marginalizado. As implementações das políticas públicas voltadas ao acesso à educação através da cultura oportunizaram aos moradores do Recife um encontro com a própria identidade de ser humano. Esses espaços de leitura e compartilhamento de conhecimento foram uma inovação, pois proporcionaram o encontro do povo com o livro. Até o final do século XIX essas pessoas sequer poderiam usufruir dos bens públicos de uso comum do povo, como as praças, parques, cujo ingresso era limitado por grades, de sorte que apenas os privilegiados poderiam deles apropriar-se. No entanto, essa apropriação literária proporcionada ao povo foi definida e controlada pelo Estado, através das elites intelectuais do Recife.

O artigo em questão analisa o curta metragem franco-belga Kiriku e a feiticeira tendo em vista as cosmovisões africanas que estão presentes nele. Isso porque, tem origem em experiências do diretor Michel Ocelot que viveu na África Ocidental na infância e teve contato com a tradição oral. Ao pensar sobre o espaço midiático em geral, sua relação com concepções eurocêntricas e, consequentemente suas ligações com o colonialismo, o artigo destaca como as representações divergem de produções majoritariamente assistidas, de modo que faz uma análise sobre os aspectos estéticos da obra evidenciando a presença de cosmogonias africanas para destacar a singularidade, e ao mesmo tempo a pluralidade de tradições da África Ocidental.

Published: July 2024

Objetivo: O objetivo da pesquisa é analisar a percepção dos graduandos em Ciências Contábeis quanto à relevância da produção científica para a sua formação acadêmica.
Metodologia: Trata-se de um estudo qualitativo com entrevistas semiestruturadas com quinze graduandos de ciências contábeis. Os dados coletados foram analisados por meio de análise de conteúdo, com o auxílio do software IRAMUTEQ.
Resultados: Os resultados apontam que os acadêmicos consideram que durante a graduação tiveram pouco contato com a produção científica, o que ocasionou a principal dificuldade citada: incompreensão da estrutura metodológica e redação científica. Os graduandos perceberam que a pesquisa científica estimula a busca por novos conhecimentos, porém o interesse em publicar tais conhecimentos não é recorrente entre eles. Percebe-se que os entrevistados reconhecem a importância da produção científica na sua formação acadêmica, contudo necessitam ter mais contato e serem incentivados a atuarem como produtores do próprio conhecimento.
Contribuições do Estudo: Esta pesquisa amplia a compreensão da importância da produção científica na formação os estudantes de Ciências Contábeis, focando nas instituições de ensino de Roraima. Ao analisar a percepção dos graduandos sobre a relevância da produção científica, o estudo fornece insights para possíveis ajustes curriculares, orientações de ensino e promoção da pesquisa nesse campo de estudo. Além disso, a pesquisa pode influenciar positivamente as políticas educacionais locais, buscando aprimorar a qualidade da formação dos futuros contadores, preparando-os de forma mais eficaz para os desafios do mercado de trabalho.
Atendimento às demandas e tolerância à corrupção: percepção de eleitores brasileiros à política do “rouba, mas faz”

Published: July 2024

Objetivo: A pesquisa teve como objetivo verificar a influência do atendimento às demandas públicas na percepção de tolerância de eleitores brasileiros à política do “rouba, mas faz”. Embora se perceba um uníssono social de rejeição à corrupção na política, existe a possibilidade de os eleitores relaxarem essa reprovação diante dos resultados que os gestores oferecem às comunidades.
Metodologia: Estudo de abordagem quantitativa, quanto aos procedimentos utilizou-se um survey, com questionário e estudo de cenários, de tolerância ao “rouba, mas faz”, como instrumento de pesquisa. Para análise dos dados foram utilizadas estatísticas descritivas e apresentação em percentuais, para as respostas das assertivas e dos cenários.
Resultados: Os resultados apontam que o brasileiro demanda políticos honestos, embora para quase 25% da população todo político seja corrupto, sem distinção; para 80% dos respondentes a principal causa dos problemas da gestão pública brasileira é a corrupção política; aproximadamente 70% dos eleitores não se utilizam de portais de transparência para decidir seu voto, embora 80% afirmem pesquisar o histórico dos candidatos antes de sua decisão.
Contribuições do Estudo: Foram percebidos aspectos relacionados com a teoria do eleitor mediano, uma vez que, apesar dos eleitores brasileiros demonstrarem intolerância a corrupção, o perfil com as características médias da população tende a votar naquele candidato que promete atender suas necessidades. Além disso, em linhas gerais, 7% da amostra reelegeria um político muito corrupto, desde que muito produtivo, enquanto 24% tolerariam a corrupção, desde que ocorra em pequena escala e venha acompanhada de obras e benefícios à sociedade, implicando que existe, em certo grau, influência do atendimento às demandas públicas na tolerância dos eleitores à política do “rouba, mas faz” no Brasil.

Zonas costeiras são regiões dinâmicas cuja morfologia é diretamente influenciada por fatores físicos naturais ou de origem antrópica. A depender do nível de ocupação e do estágio de desenvolvimento, estas áreas podem estar sujeitas a riscos associados à ocorrência de inundações ou processos erosivos que as tornam vulneráveis. Considerando esse contexto, este trabalho quantificou a vulnerabilidade relativa da costa quanto às alterações físicas entre as praias de Peroba e Redonda no município de Icapuí, litoral leste do Ceará, destacando os trechos de praia onde os efeitos na linha costa pode ser extremos. Na implementação do Índice de Vulnerabilidade Costeira, foram utilizadas as variáveis naturais geomorfologia, declividade, taxa de variação da linha de costa, amplitude média de maré, altura significativa de onda e variação do nível médio do mar. Os resultados indicaram a ocorrência de três classes de vulnerabilidade, desde moderada a muito alta. Cerca de 2.940 m (58%) foram registrados como trecho de moderada vulnerabilidade, 2.100 m (41%) de alta vulnerabilidade e cerca de 30 m (1%) muito alta vulnerabilidade. Os trechos com maior vulnerabilidade estão associados a faixas de praias arenosas e os de menor vulnerabilidade a falésias ativas constituintes dos tabuleiros costeiros e áreas de conservação.

A ordem Coleóptera possui uma grande variedade de formas, tamanhos, estratégias ecológicas e habitats. Os coleópteros coprófagos pertencem a superfamília Scarabaeoidea, família Scarabaeidae, subfamília Scarabaeinae e são conhecidos popularmente como rola-bosta. O objetivo principal do presente trabalho foi realizar o levantamento populacional dos besouros coprófagos (Coleoptera: Scarabaeide) em uma Unidade de Conservação do Leste do Maranhão. A área experimental em estudo foi dividida de três formas: Margem da estrada (borda); Cerrado senso stricto e Mata ciliar. Para realização das coletas dos besouros coprófagos, foram realizadas duas coletas, uma no mês de outubro (2020) e outra no mês de maio de (2021), utilizando armadilhas do tipo Pitifull. Para as análises estatísticas utilizou-se o programa ANAFAU. Para a análise da riqueza e curva de acumulação utilizou o programa EstimateS. Foram contabilizados 393 espécimes de Scarabaeidae, sendo 145 indivíduos para a Área 1 distribuídos em oito espécies, 149 indivíduos para a Área 2 distribuídos em oito espécies e 99 indivíduos para a Área 3 distribuídos em oito espécies, sendo obtida igualdade de riqueza observada de espécies para todas as áreas com oito espécies respectivamente. Foi analisada a diversidade das espécies entre as três fitofisionomias estudadas (Shannon-Wiener), a Área 3 teve maior índice de diversidade, sendo confirmado pelo Índice de Pielou (J). O estimador de riqueza e as curvas de acumulação obtidas para ambas as áreas revelaram que o esforço amostral não foi suficiente para quantificar totalmente as espécies e que, portanto, a riqueza de Scarabaeidae da APA do Inhamum encontra-se subamostrada.

Published: July 2024

Introduction:

Paxlovid (nirmatrelvir/ritonavir) has received endorsement
from several guidelines for treating COVID-19 in adults, but its use in children is still
uncertain.

Objectives:

This study aimed to evaluate the safety and effectiveness of paxlovid in pediatric
patients in the pediatric intensive care unit (PICU).

Methods:

A retrospective analysis was performed on children with COVID-19. The children
who received paxlovid comprised the paxlovid group; otherwise, they were referred
to as the control group.

Results:

A total of 31 children were enrolled, with 12 and 19 participants assigned to the
paxlovid and control groups, respectively. Approximately 35% had received vaccination
against the novel coronavirus. The control group exhibited a significantly lower mean
age in comparison to the paxlovid group (p < 0.001). However, no significant differences
were observed between the groups in terms of other baseline data and biochemical
indexes at admission. However, on the fifth day of drug administration, the paxlovid
group exhibited a statistically significant decrease in temperature compared to the control
group (p < 0.05). Additionally, the paxlovid group exhibited a significantly shorter
conversion time to negativity for novel coronary genes in the respiratory tract (9.5 days)
compared to the control group (16 days, p < 0.05). The administration of paxlovid did
not result in any observed adverse reactions. Merely two patients exhibited a transient elevation
in liver enzyme levels.

Conclusion:

The application of paxlovid in critically ill pediatric patients with
COVID-19 can effectively control symptoms and promote virus clearance, demonstrating
efficacy and a relatively low-risk profile.
Correlation between Serum 25 (OH) D Levels with Insulin Resistance and Metabolic Associated Fatty Liver Disease - A Retrospective Study based on Chinese Patients with Newly Diagnosed Type 2 Diabetes Mellitus
Authors: Zhao Xin , Sun Jianbin , Xin Sixu , Xu Xiumei , Zhang Xiaomei
Published: July 2024

Aims:

The objective of this study was to investigate the correlation between serum 25
hydroxyvitamin D [25(OH)D] levels and insulin resistance, as well as metabolic associated fatty
liver disease (MAFLD) in newly diagnosed with type 2 diabetes mellitus(T2DM) patients.

Method:

A retrospective analysis was conducted on 491 T2DM patients who were newly diagnosed
between January 2017 and August 2022 at Peking University International Hospital. These
patients were categorized into three groups based on their 25(OH)D levels.

Results:

The prevalence of MAFLD was significantly elevated in both the Vitamin D (VD) deficiency group and the VD insufficiency group compared to the VD sufficiency group (χ2 = 6.51, p<0.05). The patients in the VD sufficiency group had lower levels of insulin resistance, as assessed by the homeostasis model assessment when compared to the VD deficiency group and the VD insufficiency group (F = 8.61, p<0.05). Additionally, the VD sufficiency group demonstrated higher levels of β cell function in comparison to the other two groups (p<0.05, respectively).

:

A significant negative correlation was observed between 25(OH)D levels and insulin resistance, as assessed by the homeostasis model assessment in T2DM patients(r=-0.33, p<0.05 for females; r=-0.32, p<0.05 for males).

:

In male patients, 25(OH)D was identified as a protective factor against MAFLD(OR = 0.42;95%CI:0.19-0.95;p <0.05). Meanwhile, in female patients, 25(OH)D was also associated with a reduced risk of MAFLD(OR = 0.35;95%CI 0.17-0.89; p<0.05). Additionally, the study determined that the threshold values for 25(OH)D were 15.06 ng/ml in female patients and 18.79 ng/ml in male patients for predicting MAFLD.

Conclusion:

In newly diagnosed with T2DM patients, the level of 25(OH)D may be related to
insulin resistance and β cell secretion function independently and VD deficiency is an independent
risk factor for MAFLD in patients with newly diagnosed T2DM.

Authors: Liu Huli , Xie Qianyun , Zhang Yang , Yang Ying , Jiang Yan , Tang Wen , Song Sheng
Published: July 2024

Background:

Capitellar injury (CI) includes capitellar cartilage injury (CCI) and capitellar fracture (CF). A comprehensive classification of CI concurrent with
radial head fracture (RHF) that can guide surgical strategy is lacking in the literature. Therefore, this study aimed to introduce a comprehensive
classification of CI concurrent with RHF and investigate its value.

Methods:

A total of 35 patients with CI concurrent with RHF confirmed by surgical exploration were retrospectively analyzed, includingmales in 19 cases
and females in 16 cases. RHF was classified according to the Mason classification, and CI was classified into six types, including 3 types of CCI
and CF, each based on the site and degrees of injuries (comprehensive classification method proposed in this study). The classification results were
analyzed. Two radiologists were selected to independently classify the CI, and the inter- and intra-observer agreements were analyzed with kappa
statistics.

Results:

Mason Type I, II, III, and IV RHF accounted for 14.3%, 48.6%, 37.1%, and 0% of cases, respectively. Type I, II, III, IV, V, and VI CIs accounted
for 22.9%, 34.3%, 25.7%, 11.4%, 2.9%, and 2.9% of cases, respectively. Therewas no obvious relationship between the CI and RHF types (p >
0.05). All Type I CIs underwent removal, 9 Type II CIs underwent microfracture repair, and 3 Type II CIs underwent removal. All Type III CIs
underwent fixation, one Type IV CI underwent removal, and 3 Type IV CIs underwent fixation, one Type V CI underwent fixation, and one Type
VI CI underwent arthroplasty. The inter- and intra-observer kappa coefficients were 0.830 ~ 0.905 and 0.805 ~ 0.892, respectively. At 12 months
postoperatively, the elbow function evaluated by MEPS was 91, with an excellent and good rate of 97%.

Conclusion:

Different types of CI differ not only in pathology but also in treatment methods. The CI comprehensive classification put forth in this paper for the
first time reflects different types of pathology well, with high consistency and repeatability, and can guide the selection of surgical methods,
leading to satisfactory postoperative results.

Published: July 2024

To comprehensively understand molecular processes, it is essential to analyze how thermodynamic
parameters change with temperature and composition, providing valuable insights into
molecular interactions. The industry's demand for precise information on the physical and chemical
characteristics of different liquid combinations underscores the importance of such research. Researchers
employ an ultrasonic interferometer for measuring ultrasonic wave velocity, a specific
gravity bottle for liquid density determination, and an Ostwald viscometer for viscosity measurements.
The propagation of ultrasonic waves can affect the physical properties of a medium, providing
insights into the physics of liquids and solutions. Research has explored how frequency and temperature
can impact thermoacoustic characteristics. Scientists have identified the nature of the forces
between molecules, including hydrogen bonds, charge transfer complexes, and the breaking and
formation of such bonds through their investigations. By measuring ultrasonic wave velocity, liquid
density, and viscosity, researchers can analyze a range of acoustic and thermodynamic properties,
thus significantly advancing our understanding of molecular interactions within each sample. Additionally,
a comprehensive explanation of the measured parameters is provided to offer detailed insights
into the studied phenomena, enhancing the overall understanding of molecular processes in
liquid mixtures.

Published: July 2024

Background:

Vitamins are needed for the healthy functioning of the body. When these
vitamins are not in sufficient amounts in the body, they are usually taken externally with
pharmaceutical preparations. Taking vitamins into the body in the right amounts is possible by
analyzing the amounts in pharmaceutical preparations with validated methods.

Methods:

In this study, a fast, simple, easily applicable, and selective normal-phase HPLC method
was developed for the simultaneous determination of fat-soluble A, D3, E, and K1 vitamins in
pharmaceutical preparations from syrup and tablets. Separation of the vitamins was carried out on a
Zorbax CN column (250 x 4.6 mm, 5 µm) using a mixture of hexane-isopropyl alcohol (98:2, v/v) at
30°C column temperature and 1 ml/min flow rate. The detection wavelength is 280 nm. The
developed method has been validated according to ICH Harmonised Tripartite Guideline Validation
of Analytical Procedures: Text and Methodology Q2(R1) rules.

Results:

Calibration graphs are linear over the range of 10-1000 μg ml-1, 1-50 μg ml-1, 10-2000 μg
ml-1, 0.5-20 μg ml-1, and the limit of detection values were found to be 1.496, 0.280, 1.388 and 0.040
μg ml-1 for A, D3, E and K1 vitamins, respectively. Relative standard deviation values, which express
within-day and between-day repeatability, were found below 2.54%. Average recovery values were
also found at about 100.28, 101.46, 100.65, and 100.29% for A, D3, E, and K1 vitamins, respectively.

Conclusion:

The developed and validated method was successfully applied to the simultaneous
analysis of fat-soluble vitamins A, D3, E, and K1 in pharmaceutical preparations in syrup and tablet
form.
