This study highlights the synthesis of innovative polyurethane materials derived from Moringa oleifera oils extracted from two distinct sources. The oils were converted into their respective polyols through the in situ generated performic acid method. Diverse material characteristics were observed due to different agroclimatic and cultivation conditions for the sources. Extraction yields were 45.21% (source 1) and 40.32% (source 2), with acid values of 28.70 and 26.00 mg KOH per g of oil, respectively. Oleic acid constituted 79.87 and 67.11% of the oils composition, respectively. Nuclear magnetic resonance and Fourier transform infrared spectroscopy (FTIR) confirmed the hydroxylation of the oils. FTIR also identified the isocyanate structures in the synthesized polyurethane materials. Gel permeation chromatography analysis revealed a higher oligomer content in the polyol synthesized from the oil extracted from source 2. Thermogravimetric analysis demonstrated enhanced thermal stability post-oil conversion, highlighting decomposition stages for rigid and flexible segments. Differential scanning calorimetry indicated higher unsaturation in the oil extracted from source 1, resulting in an elevated crystallization temperature. Tensile testing showed increased elasticity as the [NCO]/[OH] ratio decreased in the material, emphasizing the influence of polyol and crosslinking agent concentrations on mechanical resistance of polyurethane materials. sources method 4521 45 21 45.21 1 4032 40 32 40.32 2, 2 , 2) 2870 28 70 28.7 2600 26 00 26.0 respectively 7987 79 87 79.8 6711 67 11 67.11 composition (FTIR postoil post conversion segments temperature NCO/OH NCOOH NCO / OH [NCO]/[OH 452 4 45.2 403 3 40.3 287 7 28. 260 0 26. 798 8 79. 671 6 67.1 45. 40. 67.

Poly(amidoamine)-type dendrimers (PAMAM) were synthesized by divergent routes, and generations (G0.5, G1.0, G1.5, G2.0 and G2.5) along with hydroxylated half-generation polymers (G0.5-OH, G1.5-OH and G2.5-OH) were characterized by Fourier-transform infrared spectroscopy, thermogravimetric analysis and differential scanning calorimetry. Carbon dioxide (CO2) capture tests were performed using thermogravimetric analysis. Among the absorption temperatures tested, 60 °C was the most promising: 0.77, 1.08, and 1.14 mol CO2 L 1 for G0.5-OH, G1.5-OH and G2.5-OH, respectively, of CO2 and partial pressure of 45 kPa. This showed that dendrimers with larger molecular structures have more hydroxyl groups and consequently capture more CO2. However, at low partial pressures (< 2 kPa), CO2 solubility in PAMAM increased with temperature reduction, confirmed by Henry’s solubility constant (398.4 mol m3 kPa 1, in G2.5-OH at 40 °C). According to the thermodynamic properties of CO2 solubilization, the process was spontaneous (∆Gsol < 0) and exothermic (∆Hsol < 0).

The present work reports the in situ fabrication of Ag nanoparticles (AgNPs) in polystyrene-b-poly(2-vinylpyridine) (PS-b-P2VP) over pre-patterned hydrophobic stripes on a hydrophilic glass surface. Microcontact printing (μCP) using octadecyltrichlorosilane (OTS) as “ink” was used to obtain these chemically modified substrates. A comparison of the results of the PS-b-P2VP self-assembly over a bare glass substrate and a pre-patterned glass substrate demonstrated the influence of the pattern on the film morphology. Polymeric films of Ag+ and PS-b-P2VP were prepared on a pre-patterned substrate and heated at 150 °C to enable the self-reconstruction of the polymeric matrix and the in situ formation of AgNPs (average particle size of approximately 100 nm). The AgNP/PS-b-P2VP thin films were characterized using UV-Vis spectroscopy and atomic force microscopy. The results demonstrate that the concentration of the solutions of Ag+/PS-b-P2VP used to prepare the films strongly influences the morphologies and dispersion of AgNPs. Moreover, the surface-enhanced Raman spectroscopy (SERS) activity of the fabricated polymer nanocomposites using Nile Blue as a molecular probe shows the importance of the chemical modification of the substrate in the enhancement of the SERS signal.

ABSTRACT Potassium is a nutrient with the potential to increase plant tolerance to salt stress. The aim of this study was to evaluate the production and quality of kale subjected to salt stress and potassium concentrations in a protected environment. The experimental design was in split plots, with plots composed of five nutrient solutions (control treatment, S1 - standard nutrient solution prepared in low-salinity water, 0.5 dS m-1 (500 mg L-1 of KNO3), and four nutrient solutions prepared in brackish waters (3.5 dS m-1) containing four concentrations of KNO3 (S2 - 500 mg L-1, S3 - 625 mg L-1, S4 - 750 mg L-1, S5 - 1,000 mg L-1), and subplots represented by two leaf kale cultivars (Manteiga and Manteiga da Geórgia). Leaf production variables and post-harvest physical and chemical qualities were evaluated. The saline nutrient solution with the addition of NaCl (S2) reduced production but did not reduce the post-harvest quality of kale. The extra addition of KNO3 at 25% (S3) was efficient in reducing the deleterious effects of salt stress on the variables leaf length, leaf area, leaf production, and number of bunches. The cv.

RESUMO O potássio é um nutriente com potencial para aumentar a tolerância das plantas ao estresse salino. O objetivo deste estudo foi avaliar a produção e a qualidade da couve submetida ao estresse salino e às concentrações de potássio em ambiente protegido. O delineamento experimental adotado foi em parcela subdivididas, sendo as parcelas compostas por cinco soluções nutritivas (tratamento controle, S1 - solução nutritiva padrão usando água de baixa salinidade, 0,5 dS m-1 (500 mg L-1 de KNO3), e quatro soluções nutritivas preparadas em águas salobras (3,5 dS m-1) contendo quatro concentrações de KNO3 (S2 - 500 mg L-1, S3 - 625 mg L-1, S4 - 750 mg L-1, S5 - 1.000 mg L-1). As subparcelas foram representadas por duas cultivares de couve folha (Manteiga e Manteiga da Geórgia). Foram avaliadas as variáveis de produção de folhas e qualidades físicas e químicas pós-colheita. A solução nutritiva salinizada com adição de NaCl (S2) reduziu a produção, mas não reduziu a qualidade pós-colheita da couve folha. A adição extra de KNO3 em 25% (S3) foi eficiente para reduzir o efeito deletério do estresse salino sobre as variáveis comprimento de folha, área foliar, produção e número de maços. A cv.

ABSTRACT Alternative techniques for cultivation without soil are widespread; however, studies comparing hydroponic systems still need to be studied, mainly in semi-arid regions. The present study aimed to evaluate the effect of hydroponic systems on the yield and quality of lettuce cultivars subjected to different electrical conductivities of the nutrient solution. The research was conducted in a greenhouse, adopting a completely randomized design in a 2 × 2 × 3 factorial scheme, being two lettuce cultivars (Cinderela and Rubinela), two electrical conductivities (2.90 and 1.6 dS m-1), and three hydroponics systems (NFT, semi-hydroponic, and floating), with three replications. The number of leaves, leaf succulence, specific leaf area, leaf fresh mass, total dry mass, leaf area, titratable acidity, vitamin C, and soluble solids were evaluated. Cinderela cultivar showed the highest average leaf fresh mass, total dry mass, leaf area, and vitamin C values. The NFT and floating systems provided the highest leaf yield and quality, especially in the solution of 1.60 dS m-1.

ABSTRACT The semi-arid region faces problems related to water deficit and the presence of brackish water that compromise crop performance. Therefore, irrigation frequency can enhance the growth of agricultural crops of interest even under salt stress conditions. In this context, the objective of the present study was to evaluate different irrigation frequencies with water of higher and lower salinity on the agronomic performance of millet. The experiment was conducted from September to November 2020, in the experimental area of the Auroras Seedling Production Unit, belonging to the Universidade da Integração Internacional da Lusofonia Afro-Brasileira, Redenção, Ceará, Brazil. The experimental design used was completely randomized in a 4 × 2 factorial arrangement, with five repetitions. The first factor corresponded to four irrigation frequencies (F1 - daily irrigation; F2 - irrigation every two days; F3 - irrigation every three days; F4 - irrigation every four days) and the second factor consisted of two levels of electrical conductivity of irrigation water (0.3 and 5.0 dS m-1). Salt stress (5.0 dS m-1) negatively affected leaf area, plant height, stalk diameter, panicle length, and leaf, stem, panicle, and total dry mass of millet, under daily and four-day irrigation frequencies. Increasing the interval in irrigation frequency to beyond two days negatively affects the agronomic performance of millet crop, regardless of the electrical conductivity of water used (0.3 or 5.0 dS m-1). Under salt stress conditions, adopting irrigation frequencies between two and three days can be a viable alternative for irrigation management in pearl millet crop. semiarid semi arid Therefore conditions context 2020 Unit AfroBrasileira, AfroBrasileira Afro Brasileira, Brasileira Afro-Brasileira Redenção Ceará Brazil arrangement repetitions F1 F (F 0.3 03 0 3 (0. 50 5 5. m1. m1 m 1 .

RESUMO A região semiárida apresenta problemas relacionados ao déficit hídrico e presença de água salobra que comprometem o desempenho das culturas. Assim, a frequência de irrigação pode promover melhores condições de desenvolvimento das culturas de interesse agrícola mesmo em condições de estresse salino. Neste sentido, objetivou-se avaliar diferentes frequências de irrigação com água de maior e menor salinidade sobre desempenho agronômico do milheto. O experimento foi realizado no período de setembro a novembro de 2020, na área experimental da Unidade de Produção de Mudas Auroras, pertencente a Universidade da Integração Internacional da Lusofonia Afro-Brasileira, Redenção, Ceará. O delineamento experimental utilizado foi inteiramente casualizado em arranjo fatorial 4 × 2, com cinco repetições. O primeiro fator corresponde a quatro frequências de irrigação (F1 - irrigação diária; F2 - irrigação a cada dois dias; F3 - irrigação a cada três dias; F4 - irrigação a cada quatro dias) e o segundo consistiu em dois níveis de condutividade elétrica da água de irrigação (0,3 e 5,0 dS m-1). O estresse salino (5,0 dS m-1) afetou negativamente a área foliar, altura da planta, diâmetro do colmo, comprimento da panícula, massa seca da folha, caule, panícula e total do milheto, sob irrigação diária e cada quatro dias. O aumento do intervalo na frequência de irrigação acima de dois dias afeta o desempenho agronômico do milheto, independente da condutividade elétrica da água (0,3 ou 5,0 dS m-1). Em condições de estresse salino, adotar frequências de irrigação entre dois e três dias pode ser uma alternativa viável para o manejo da irrigação do milheto.

Abstract The present study sought to evaluate the antimicrobial and anti-adherent potential of Eucalyptus radiata essential oil against food-borne strains of Escherichia coli. The study was performed using the Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC). In addition, the disk diffusion technique was used to evaluate the association of Eucalyptus radiata essential oil with synthetic antimicrobials. The Minimum Inhibitory Adherence Concentration (MIC) was also performed. The results revealed that E. radiata showed antimicrobial activity against the E. coli strains tested, with MIC values ranging from 500 μg/mL to 1000 μg/mL and MBC values ranging from 500 μg/mL to 1,024 μg/mL. As for the associations, it was observed that E. radiata oil exhibited a synergistic effect for some antibiotics, especially Ceftriaxone, with greater interference from the essential oil. Furthermore, it was effective in inhibiting the adherence of bacterial strains of E. coli, showing a more significant antibiofilm effect than the antibacterial agent 0.12% chlorhexidine digluconate. In summary, the essential oil of E. radiata showed antimicrobial potential against strains of E. coli of food origin, and can therefore, through in-depth studies, be used alone or in association with synthetic antimicrobials to combat infections caused by this pathogen. antiadherent anti adherent foodborne borne (MIC MBC. .

Abstract This study compares the effects of virus-cell interactions among SARS-CoV-2 variants of concern (VOCs) isolated in Brazil in 2021, hypothesizing a correlation between cellular alterations and mortality and between viral load and transmissibility. For this purpose, reference isolates of Alpha, Gamma, Zeta, and Delta variants were inoculated into monolayers of Vero-E6 cells. Viral RNA was quantified in cell supernatants by RT‒PCR, and infected cells were analyzed by Transmission Electron Microscopy (TEM) for qualitative and quantitative evaluation of cellular changes 24, 48, and 72 hours postinfection (hpi). Ultrastructural analyses showed that all variants of SARS-CoV-2 altered the structure and function of mitochondria, nucleus, and rough endoplasmic reticulum of cells. Monolayers infected with the Delta variant showed the highest number of modified cells and the greatest statistically significant differences compared to those of other variants. Viral particles were observed in the cytosol and the cell membrane in 100 % of the cells at 48 hpi. Alpha showed the highest mean particle diameter (79 nm), and Gamma and Delta were the smallest (75 nm). Alpha and Gamma had the highest particle frequency per field at 48 hpi, while the same was observed for Zeta and Delta at 72 hpi and 24 hpi, respectively. The cycle threshold of viral RNA varied among the target protein, VOC, and time of infection. The findings presented here demonstrate that all four VOCs evaluated caused ultrastructural changes in Vero-E6 cells, which were more prominent when infection occured with the Delta variant. viruscell virus SARSCoV2 SARSCoV SARS CoV 2 SARS-CoV- (VOCs 2021 transmissibility purpose VeroE6 VeroE Vero E6 E Vero-E RTPCR RT PCR RT‒PCR TEM (TEM 7 .

The reactivity and steric hindrance of optically active tertiary alcohols limit the development of more direct enantioselective methodologies for their synthesis, such as kinetic resolution (KR). In this work, we optimized the reaction conditions of an enzymatic KR of two tertiary benzyl bicyclic alcohols using readily available reagents and biocatalyst. Studies were conducted with 1-methyl-1,2,3,4-tetrahydronaphthalen-1-ol and 1-methyl-2,3-dihydro-1 H-inden-1-ol as substrates and commercial lipase A from Candida antarctica (CAL-A) as biocatalyst for the enantioselective transesterification of these racemic tertiary alcohols. After varying the reaction parameters, such as acyl donor, solvent, and enzyme/substrate ratio, the (R)-esters were obtained with high conversions (44-45%) and excellent enantiomeric excess (96-99%) in only 4-5 h, to our knowledge being the best result for KR of the evaluated tertiary alcohols in terms of reaction rate, conversion, and enantioselectivity reported so far. synthesis KR. .

Cancer is one of the major causes of death worldwide, and breast cancer is the most prevalent and deadly type among women. Despite the side effects and the phenomena of chemoresistance associated with the drugs involved, chemotherapy remains the main therapeutic strategy to combat and control breast cancer. Therefore, several new classes of compounds against breast cancer have been explored, in an effort to identify new drug candidates with alternative mechanisms of action. The principal results of such exploration, focusing on caged xanthones, thiosemicarbazones and photosensitizers, are presented in this review, along with the main aspects of the drug discovery process against breast cancer. More specifically, the design, structure-activity relationship investigations and anti-breast cancer properties of these three classes are described and discussed in this work. worldwide women involved Therefore explored action exploration xanthones photosensitizers review specifically design structureactivity structure activity antibreast anti work

In this study, we describe a light-driven photocatalytic decarboxylation of palmitic acid and related fatty acids using Chlorella variabilis fatty acid photodecarboxylase (CvFAP). By utilizing violet light emitting diode (LED) light (50 W; 397 nm), we achieved a remarkable conversion efficiency of 99% within just 4 min, surpassing the previous 79% conversion achieved in 60 min using blue LED light (300 W; 439 nm). Importantly, the use of 50 W violet LED light also resulted in a lower enzyme photoinactivation rate when compared to 300 W blue LED. Comparing the whole-cell biocatalyst with the enzymatic extract, we found that the former demonstrated superior catalytic performance and reduced susceptibility to photoinactivation. Furthermore, whole-cell biocatalyst reuse was demonstrated after five sequential batches. Employing this approach, we successfully synthesized 26 mmol L-1 h-1 of pentadecane, showcasing a promising strategy to improve productivity. These findings represent a significant advancement in CvFAP photodecarboxylation processes compared to the literature, utilizing an alternative light source, with potential implications to the biofuel sector. study lightdriven driven CvFAP. .

Abstract Planting with higher density in sugarcane is one of the practices used to overcome low productivity. However, this planting material is equivalent to 25% of the total cost of production, being one of the main expenses for cultivation. In this sense, the present work aims to evaluate the productivity and economic viability of sugarcane as a function of planting density. The experiment was carried out at Usina Monte Alegre in the municipality of Mamanguape, Paraíba, Brazil, from March 2021 to January 2022 with the variety RB92579. Seven planting density were studied: T1: 7 gems m-1, T2: 10 gems m-1, T3: 12 gems m-1, T4: 11 gems m-1, T5: 15 gems m-1, T6: 17 gems m-1, T7: 24 gems m-1, in randomized blocks with four replications. Growth, productivity and economic viability were evaluated. The highest productivity of cane and sugar, 77.69 ton ha-1 and 10.390 ton ha-1, respectively, was with planting density of 17 and 24 gems-1. While the minimum productivity of cane (61.313 ton ha-1) and sugar (7.924 ton ha-1) was recorded at sowing density of 7 and 11 gems-1. However, cultivation density with 7 and 10 gems m-1 were the ones that provided the highest profitability around 50%, followed by density of 12, 15 and 17 gems m-1 with an average of 45% profit and 11 and 24 gems m-1 with the lowest proportion of profit on average 38%. The cultivation with 17 gems m-1 of cane provides in cane-plant, variety RB92579, greater productivity with a profit rate of 45%, being the most suitable.

Resumo O plantio com maiores densidades na cana-de-açúcar é uma das práticas utilizadas para superar a baixa produtividade. Contudo, esse material de plantio equivale a 25% do custo total de produção, sendo uma das principais despesas para o cultivo. Nesse sentido, o presente trabalho objetiva avaliar a produtividade e viabilidade econômica de cana-de-açúcar em função das densidades de plantio. O experimento foi realizado na Usina Monte Alegre no município de Mamanguape, Paraíba, Brasil, durante março de 2021 a janeiro de 2022 com a variedade RB92579. Sendo estudadas sete densidades de plantio: 7,10, 12, 13, 15, 17 e 24 gemas m-1, em blocos casualizados com quatro repetições. Foram avaliados o crescimento, a produtividade e a viabilidade econômica.

La distorsión de la imagen corporal es una alteración en la percepción del cuerpo que puede repercutir en la salud. Este estudio busca estimar, entre las mujeres participantes del Estudio Longitudinal de Salud del Adulto (ELSA-Brasil) que viven en Bahía, Brasil, la prevalencia de precisión y distorsión de la imagen corporal e investigar asociaciones con las características socioeconómicas, el estilo de vida y la busca de atención ginecológica. Participaron 609 mujeres que tenían entre 50 y 69 años que contestaron los cuestionarios aplicados cara a cara entre 2012 y 2014. Se utilizó la escala de siluetas de Stunkard para investigar la percepción precisa o distorsionada para más o menos peso. El cociente de riesgo relativo (RR) se calculó a través de regresión logística multinomial utilizando el Stata 13. La mayoría de los participantes tiene una perspectiva precisa del propio cuerpo (53,7%). Entre las personas con percepción distorsionada hay una tendencia a la distorsión para menos peso (38,1%). En el análisis de regresión multinomial, las variables raza/color y escolaridad permanecieron asociadas con la distorsión para menos peso, siendo la primera positivamente asociada con la distorsión para menos peso entre las mujeres pardas (RR = 1,89; IC95%: 1,13-3,16) y negras (RR = 2,10; IC95%: 1,25-3,55), mientras la segunda entre las mujeres que estudiaron hasta la enseñanza secundaria (RR = 1,65; IC95%: 1,18-2,33). No hubo asociaciones con las otras variables ni con la distorsión para más peso. Los resultados contribuyen para explicar las relaciones entre la percepción de la imagen corporal y los factores socioeconómicos, demostrando que mujeres de diferentes razas/colores y diferentes niveles de educación se influyen de distintas formas a través de discursos sociales, lo que impacta en la percepción de su imagen corporal. salud estimar ELSABrasil ELSA Brasil (ELSA-Brasil Bahía socioeconómicas ginecológica 60 5 6 201 2014 RR 13 53,7%. 537 53,7% . 53 7 (53,7%) 38,1%. 381 38,1% 38 1 (38,1%) razacolor raza color 1,89 189 89 IC95% IC95 IC 1,133,16 113316 1,13 3,16 3 16 1,13-3,16 2,10 210 2 10 1,253,55, 125355 1,25 3,55 , 25 55 1,25-3,55) 1,65 165 65 1,182,33. 118233 1,18 2,33 18 33 1,18-2,33) socioeconómicos razascolores razas colores sociales 20 53,7 (53,7% 38,1 (38,1% 1,8 8 IC9 133 1,133,1 11331 113 1,1 316 3,1 1,13-3,1 2,1 21 253 1,253,55 12535 125 1,2 355 3,5 1,25-3,55 1,6 182 1,182,33 11823 118 233 2,3 1,18-2,33 53, (53,7 38, (38,1 1, 1,133, 1133 11 31 3, 1,13-3, 2, 1,253,5 1253 12 35 1,25-3,5 1,182,3 1182 23 1,18-2,3 (53, (38, 1,133 1,13-3 1,253, 1,25-3, 1,182, 1,18-2, (53 (38 1,13- 1,253 1,25-3 1,182 1,18-2 (5 (3 1,25- 1,18- (

Body image distortion is an alteration in the perception of the body that can have repercussions on health. This study aims to estimate the prevalence of body image accuracy and distortion among women participating in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) living in Bahia State, Brazil, and to investigate associations with socioeconomic characteristics, lifestyle, and gynecological care seeking. A total of 609 women aged 50 to 69 years participated in the study, who answered face-to-face questionnaires from 2012 to 2014. The Stunkard silhouette scale was used to investigate accurate or distorted perception for more or less weight. The relative risk ratio (RR) was calculated by multinomial logistic regression using Stata 13. Most participants have an accurate perception of their own bodies (53.7%). Among those with distorted perception, there is a tendency to distort towards less weight (38.1%). In the multinomial regression analysis, the variables race/skin color and education remained associated with the distortion towards underweight. The race/skin color variable was positively associated with the distortion towards underweight among Mixed-race women (RR = 1.89; 95%CI: 1.13-3.16) and black (RR = 2.10; 95%CI: 1.25-3.55), while the education variable among those with up to high school education (RR = 1.65; 95%CI: 1.18-2.33). There were no associations with the other variables or with distortion for more weight. The results contribute to explaining the relationships between body image perception and socioeconomic factors, revealing that women of different races/skin colors and varying educational levels are influenced in different ways by social discourses, impacting the perception of their body image. health ELSABrasil ELSA Brasil (ELSA-Brasil State Brazil characteristics lifestyle seeking 60 5 6 facetoface face 201 2014 RR 13 53.7%. 537 53.7% . 53 7 (53.7%) 38.1%. 381 38.1% 38 1 (38.1%) analysis raceskin race skin Mixedrace Mixed 1.89 189 89 95%CI 95CI CI 95 1.133.16 113316 1.13 3.16 3 16 1.13-3.16 2.10 210 2 10 1.253.55, 125355 1.25 3.55 , 25 55 1.25-3.55) 1.65 165 65 1.182.33. 118233 1.18 2.33 18 33 1.18-2.33) factors racesskin races discourses 20 53.7 (53.7% 38.1 (38.1% 1.8 8 9 133 1.133.1 11331 113 1.1 316 3.1 1.13-3.1 2.1 21 253 1.253.55 12535 125 1.2 355 3.5 1.25-3.55 1.6 182 1.182.33 11823 118 233 2.3 1.18-2.33 53.

Abstract Sarcopenia is a pathology resulting from a progressive and severe loss of muscle mass, strength, and function in the course of aging, which has deleterious consequences on quality of life. Among the most widespread studies on the issue are those focused on the effect of different types of physical exercise on patients with sarcopenia. This randomized controlled study aimed to compare the effects of a whole-body vibration exercise (WBV) session on the inflammatory parameters of non-sarcopenic (NSG, n=22) and sarcopenic elderly (SG, n=22). NSG and SG participants were randomly divided into two protocols: intervention (squat with WBV) and control (squat without WBV). After a one-week washout period, participants switched protocols, so that everyone performed both protocols. Body composition was assessed by dual-energy radiological absorptiometry (DXA) and function through the six-minute walk test (6MWD) and Short Physical Performance Battery (SPPB). Plasma soluble tumor necrosis factor receptors (sTNFR) were determined by enzyme-linked immunosorbent assay (ELISA) and measured before and immediately after each protocol. After exercise with WBV, there was an increase in sTNFR2 levels in the NSG (P<0.01; d=-0.69 (-1.30; -0.08) and SG (P<0.01, d=-0.95 (-1.57; -0.32) groups. In conclusion, an acute session of WBV influenced sTNFr2 levels, with sarcopenic individuals showing a greater effect. This suggested that WBV had a more pronounced impact on sTNFr2 in those with loss of muscle strength and/or physical performance. Additionally, WBV is gaining recognition as an efficient strategy for those with persistent health issues. mass aging life sarcopenia wholebody whole body (WBV nonsarcopenic non NSG, (NSG n=22 n22 n 22 SG, (SG n=22. . protocols squat WBV. oneweek one week period dualenergy dual energy DXA (DXA sixminute six minute 6MWD MWD (6MWD SPPB.
