Authors: Rodrigues Elsa , Pintassilgo Joaquim
Published: June 2024

João de Deus Ramos, inspirado pelo movimento da Escola Nova, foi ao Brasil em 1928 estudar a diferenciação entre Portugal e Brasil através da educação e da poesia. Durante a sua estadia visitou escolas, colégios, academias, bibliotecas, institutos científicos e de assistência humanitária. No final da sua viagem pedagógica proferiu duas comunicações, uma sobre literatura onde abordou a poesia de João de Deus, Antero de Quental e Olavo Bilac, e outra sobre educação, onde divulgou os Jardins-Escolas João de Deus e o seu futuro projeto educativo, Bairro Escolar do Estoril. Igualmente participou na 2ª Conferencia Nacional de Educação, realizada em Belo Horizonte, onde conheceu as principais preocupações educativas brasileiras. O fruto dos conhecimentos adquiridos está patente no acervo bibliográfico do Museu João de Deus que possui manuais escolares brasileiros que lhe foram oferecidos nessa ocasião e nos anos seguintes. Partindo, sobretudo, da análise dessas obras brasileiras, assim como através da reflexão sobre a imprensa escrita, pretende este artigo explicar de que modo a visita ao Brasil teve impacto nos projetos educativos de João de Deus Ramos, já que alguns manuais escolares foram bastante usados em contexto de sala nos Jardins-Escolas João de Deus e outras ideias foram aproveitadas para o funcionamento do Bairro Escolar do Estoril.

Authors: Menezes Roni Cleber de
Published: June 2024

O artigo propõe explorar as vinculações do método de ensino da leitura de João de Deus com a agenda política modernizadora encetada em Portugal no último quarto do Oitocentos, objetivando perscrutar as estratégias adotadas para sua difusão no reino e em outras partes do mundo atlântico de língua portuguesa, principalmente o Brasil, para isso sopesando as interrelações do criador do método com os grupos políticos e intelectuais portugueses associados à Geração de 70. Tanto aquelas vinculações quanto essas estratégias são estudadas como parte da mobilização de parcela das camadas letradas portuguesas que, encontrando no referido método uma plataforma de atuação que lhes auxiliasse em seus objetivos de intervenção política e cultural, fornecesse-lhes mais um dispositivo a fim de superar a percepção de decadência e/ou atraso que, no seu entender, era experimentada pela sociedade lusitana.

Published: June 2024

Este trabalho tem como intuito realizar um levantamento da produção acadêmica sobre a circulação de ideias pedagógicas em teses e dissertações produzidas no Brasil e em Portugal entre 2000 e 2020. Consideramos que estes estudos representam uma importante dimensão da articulação do campo educacional luso-brasileira, constituindo trabalhos de fôlego, em geral mais aprofundados do que artigos ou resumos publicados em anais de eventos científicos. As fontes dos dados compreendem repositórios e sites que disponibilizam a produção acadêmica em ambos os países. Quanto ao aspecto teórico-metodológico, optou-se pela utilização de quatro descritores genéricos – “Educação”, “Brasil”, “Portugal” e “luso-brasileiro”. Foram realizados três mapeamentos, com caminhos metodológicos e ferramentas de busca distintas, que possibilitaram a realização de um primeiro balanço desse universo de fontes. A existência de oferta muito baixa de pós-graduações da especialidade em História da Educação contribuiu para resultados quantitativamente menores em Portugal. No caso brasileiro, há um conjunto bastante significativo de teses e dissertações, com temáticas bastante heterogêneas, que demanda análises complementares, envolvendo atividades de coorientação e composição das bancas das sessões de defesa. Trata-se de uma abordagem profícua, que pode explicitar quais pesquisadores operam um intercâmbio acadêmico entre Brasil e Portugal. Outra possibilidade de retomada desse mapeamento está associada à realização de atividades como doutorado-sanduíche, períodos de intercâmbio e estágio, desenvolvimento de projetos, composição de grupos de pesquisa, entre outros.

Published: June 2024

Background: The Asiatic black bear (Ursus thibetanus) is a federally protected species facing conservation concerns due to habitat depletion, food and environment driven altitude migration and its conflicting domain with humans. This study, conducted in the Fambonglho Wildlife Sanctuary, Sikkim Himalaya, emphasizes the need to understand seasonal variations in bear ecology and human interactions. Methods: Field surveys for four seasons viz. Spring (April-June), Summer (July-September), Autumn (October-December) and Winter (January-March) and interviews in the fringe villages (2021-2023), human-bear conflict secondary data (2019-2022) and camera trap data (2016-2017) were analysed using the GIS and statistical tools, revealing specific spatial distribution and seasonal patterns of human-bear conflicts. Result: Bears in Sikkim’s Fambonglho Wildlife Sanctuary, flourish mostly at 2200-2400 meter above mean sea level, in mixed temperate forests, exhibits bimodal activity and non-hibernating behaviour. Conflicts peak in summer and autumn, with 98.4% crop raiding on maize and livestock depredation peaking in autumn (p = less than 0.0001). Settlement proximity peaks in June-September (41%) and decreases in winter (59.9%). Locals rank bears as the primary threat (40.77%, rank 1). Understanding these dynamics informs conservation strategies for harmonious coexistence in the fragile Himalayan ecosystem.

Published: June 2024

Blended Learning als Kombination aus Präsenz- und Onlinelehre hat im Zuge der Digitalisierung der Hochschullehre zunehmend Verbreitung gefunden. Hochschulen stehen vor der Herausforderung, bestehende Lehrveranstaltungskonzeptionen zu hinterfragen und digitale Medien didaktisch sinnvoll zu integrieren. Die Arbeit soll die Frage beantworten, wie Blended Learning gestaltet sein muss, damit es erfolgreich ist. Im Vergleich zu bestehender Forschung liegt der Vorteil der durchgeführten Analyse darin, dass sich die Aussagekraft der Ergebnisse aufgrund der weitgefassten Definition von Blended Learning, der theoretischen Herangehensweise und Fallauswahl sowohl auf unterschiedliche Blended-Learning-Konzepte als auch Lehrveranstaltungen und Fachrichtungen erstreckt. Dies erhöht die Generalisierbarkeit und den Nutzen der Erkenntnisse. Im Rahmen der Analyse wurden qualitative, leitfadengestützte Interviews mit Studierenden (N=60) und Dozierenden (N=21) unterschiedlicher Fachrichtungen an zwei deutschen Universitäten geführt. Die Auswertung erfolgte mittels qualitativer Inhaltsanalyse nach Mayring. Ergebnis ist ein Katalog relevanter Faktoren, der konkrete Umsetzungshinweise, wirkende strukturelle Rahmenbedingungen sowie Herausforderungen für erfolgreiche Blended-Learning-Veranstaltungen beinhaltet. Es wird deutlich, dass Herausforderungen neben der Funktionsfähigkeit digitaler Medien vor allem im Erstellungs- und Betreuungsaufwand bzw. teilweise datenschutz- oder prüfungsrechtlichen Einschränkungen für Dozierende bestehen. Hier liegt der Handlungsbedarf aktuell bei der Hochschule, bürokratische Abläufe zu straffen, ausreichend Unterstützung bereitzustellen und so Anreize für Dozierende zu schaffen, zukunftsorientierte Hochschullehre anzubieten.

Published: June 2024

MSMEs have an important role in a nation's economy because of their contribution to national sales and employment. Moreover, the structure of business entities in Indonesia is still dominated by small and medium-sized enterprises (SMEs). Small- and medium-sized enterprises (SMEs) are compelled to compete on the global market due to the numerous blows from global competition and the prospect of recession. To increase the competitiveness of domestic MSMEs so that they can excel on the international stage, strategic and effective methods are required, such as implementing the marketing mix. Community service through a marketing mix strategy aims to increase MSMEs in Gresik Regency's comprehension of how to implement marketing mix strategies in order to prepare themselves for entry into the global market, which will result in increased sales. The method is implemented in three stages from March to October 2023: the preparation stage, the implementation stage, and the evaluation stage. The preparatory phase commences with routine coordination with partners and condition analysis. The implementation phase is subsequently executed via training, mentoring, question-and-answer sessions, and case discussions. In the evaluation phase, a pre-test, post-test, question-and-answer session, and questionnaire are utilized. Target partners are actively involved at all stages, so that the output targets can be achieved well. The implementation has resulted in an increase in MSMEs' knowledge of the marketing mix, which includes product, place, promotion, and price, as well as an increase in MSMEs' sales due to their increased global marketing reach. This community service also contribute to the achievement of Sustainable Development Goals 8 (Decent Work and Economic Growth) and 9 (Industry, Innovation, and Infrastructure).

West Kalimantan Province is one of the provinces that has a large area of oil palm plantations which can become integrated cattle farms. Oil palm plantations provide a source of feed that comes from palm oil processing waste and green grass around the oil palm trees. However, this waste contained not sufficient nutrients if given directly, so needed feed processing to increase the nutrition. The community service team from the Faculty of Veterinary Medicine, Universitas Airlangga carried out activities to increase the knowledge and skills of farmers in processing palm oil waste feed and carried out reproductive examination activities on female cattle. The output target to be achieved is increasing the ability of farmers to make feed from palm oil waste that can sufficient for livestock nutritional needs and increased of reproductive health of cows. This activity held on 20 – 23 July 2023 in Tonang Village, District. Sengah Temila, Kab. Landak, West Kalimantan. The activity was attended by 40 participants consisting of breeders, medical officers and veterinarians from the Dinas Ketahanan Pangan, Pertanian dan Perikanan Kabupaten Landak dan Dinas Perkebunan dan Peternakan Provinsi Kalimantan Barat. The first day's activities were carried out by delivering outreach and training materials on processing palm oil waste feed through silage and fermentation methods, making UMB and UMMB, and carrying out reproductive examinations and treatment of female cattle. The outcomes that have been achieved include increasing farmers' understanding and skills regarding how to make silage and palm frond fermentation, as well as UMB and UMMB as additional feed. Health and reproductive disorders examination of female cattle were carried out on 2 female cattle belonging to the Koperasi Produsen Landak Mandiri and 17 female cattle belonging to the Alam Raya Hijau Group. Based on the examination, data was obtained that 7 cows were pregnant, 1 cow had endometritis, and 11 cows were declared to be in normal reproductive condition. The conclusion that can be drawn from this activity is that the participants' knowledge about the given topic increases and the reproductive health of female cattle can be handled with appropriate examination and treatment.

Published: June 2024

Fluorinated cytokinins have emerged as promising alternatives to traditional cytokinins in plant tissue culture, offering enhanced stability and bioactivity. However, their metabolic fate and impact on endogenous cytokinin profiles remain largely unexplored. This study investigated the cytokinin metabolism of Phalaenopsis orchids under varying exogenous cytokinin treatments (BA, FmT, FmTR) and culture conditions (open vs. closed containers). The results reveal distinct metabolic profiles associated with each treatment, highlighting the complex interplay between exogenous and endogenous cytokinin levels. Additionally, we proposed an alternative inactivation pathway involving the conversion of FmTR and BA to pT and pTR. These findings provide valuable insights into the intricate relationship between cytokinin metabolism and plant growth under in vitro conditions, with implications for optimizing micropropagation protocols
A Transformative Technology Linking Patient’s mRNA Expression Profile to Anticancer Drug Efficacy
Authors: Yeh Chen , Lin Shu-Ti , Lai Hung-Chih
Published: June 2024

As precision medicine such as targeted therapy and immunotherapy often have limited accessibility, low response rate and evolved resistance, it is urgent to develop simple, low-cost, and quick-turnaround personalized diagnostic technologies for drug response prediction with high sensitivity, speed, and accuracy. Major challenges of drug response prediction strategies employing digital database modeling are the scarcity of labeled clinical data, applicable only to a few classes of drugs, and losing the resolution at the individual patient level. Although these challenges have been partially addressed by large-scale cancer cell line datasets and more patient-relevant cell-based systems, the integration of different data types and data translation from pre-clinical to clinical utilities are still far-fetched. To overcome current limitations of precision medicine with a clinically proven drug response prediction assay, we have developed an innovative and proprietary technology based on in vitro patient testing and in silico data analytics. First, a patient-derived gene expression signature was established via transcriptomic profiling of cell-free mRNA (cfmRNA) from the patient’s blood. Second, a gene-to-drug data fusion and overlaying mechanism to transfer data was performed. Finally, a semi-supervised method was used for database searching, matching, annotation and ranking of drug efficacies from a pool of ~700 approved, investigational or clinical trial drug candidates. A personalized drug response report can be delivered to inform clinical decision within a week. The PGA (Patient-derived Gene expression-informed Anticancer drug efficacy) test has significantly improved patient outcomes when compared to the treatment plans without PGA support. Implementation of PGA, which combines patient-unique cfmRNA fingerprints with drug mapping power, has the potential to identify treatment options when patients are no longer responding to therapy and when standard-of-care is exhausted.
Evaluation and Modeling the Performance of Rice Husk Gasifier Cook Stove for Household Energy Use
Authors: Fetene Mersha A. , Tikuneh Dessye B.
Published: June 2024

This research paper aims to evaluate and model the performance of rice husk gasifier cook stoves for household energy use, a byproduct of rice milling. The study aims to address environmental issues and promote the use of rice husk as a renewable energy source and pest repellent in stoves. The study compared insulated and non-insulated gasifier stoves using rice husk gasification. The study compared the start-up time of insulated and non-insulated gasifier stoves, where the insulated stove showed a lower start-up time, but there was no significant difference at a 5% probability level. The temperature change also was not significant, as heat transfer and temperature change started when the husk was ignited. The burner stoves had different size and volume. The maximum operated or flame temperature was 1,190.30oC at room or minimum temperature of 27.33 oC, whereas the average temperature was 758.916oC for the non-insulated type of gasifier stove. The insulated gasifier stove also observed maximum and average temperatures of 518.30 oC and 289.014oC respectively at the same room temperature. The operating time of stoves directly influences the fuel consumption rate, specific gasification rate, and combustion zone rate of stoves. The fuel consumption rate has a significant effect on the type of gasifier stove, with the maximum rates being 3.820 and 2.099 kg/hr. The time to consume rice husks to gasify them depends on the density of the rice husk, reactor volume, and fuel consumption rate. The average specific gasification rate for insulated and non-insulated stoves is 106.45 and 120.63 kg/m2h, respectively. The fuel or rice husk holding capacity of each type of stove is significant at a 5% level, with the amount of rice husk and biochar produced being 1.18kg and 0.27kg for insulated stoves, and 2.511kg and 0.688kg for non-insulated stoves, respectively. The performance of gasifier stoves varies based on the bio char conversion rate, with non-insulated stoves producing a higher bio char mass per rice husk. Multiple regression analysis was used to model the relationship between time elapse with temperature and heat energy. The Squirrel-2020 data logger was used to measure the temperature produced by burning rice husks in the reactor of the stove as well as related generated and losses of heat. A relationship between the heat energy produced and the operating time of gasifier stoves was conducted to estimate the model. The cubic polynomial model was found to be the best predictive model fit for all variables of this study.
A Decisive First Test and The Refutation of the Hypothesis of Quantum Gravity
Authors: Unnikrishnan CS
Published: June 2024

A quantum theory of gravity is among the most pursued goals in physics. I present a definitive and direct experimental proof that refutes the widely believed hypothesis of quantum gravity. The detections of astrophysical gravitational waves (GW) are inferred from the differential oscillations of suspended mirrors of optical interferometers like the aLIGO detectors. If gravity is indeed quantized, then the average energy $\bar{E}$ in the minute oscillations of the mirrors, at a frequency $\nu$, corresponds to the absorption of an integer number $N$ gravitational quanta with total energy $E_{gw}=Nh\nu$. The coherent and coincident detections across large separations of detectors, and also the constraint of the equivalence principle, dictate that the average number of quanta $\bar{N}$ forcing the oscillations obeys $\bar{N}\gg 1$, or $1/\sqrt{\bar{N}}\ll 1$. However, the average energy $\bar{E}$ in the differential oscillations is smaller than the energy of a single quantum of GW radiation at the detected astrophysical GW frequencies. This startling finding implies that $\bar{N} <1$, which is physically impossible if gravity is quantized. This singular contradiction refutes the long-held hypothesis that gravity is quantized.

Authors: Drescher Adrian , Schwingshackl Lisa , Kienberger Marlene
Published: June 2024

High quantities of biomass produced in greenhouses create environmental problems, as this side stream and its downgraded products are not further used in the production cycle. The aim of our research was the identification and semi-quantification of molecules extracted from vegetative tomato plant residues with sustainable green alternative solvents using vacuum-assisted soxhlet and solid-liquid extraction to evaluate the possibilities for high-value applications. To identify compounds, GC-MS analysis, and the Folin-Cioalteau method was used. In sum, 285 different compounds have been assigned to 383 detected peaks using GC-MS analysis. The solvents 2-MTHF and ethyl acetate, compared to ethanol and hexane, provided better results with a maximum number of 99 ± 8.83 compounds, a maximum total concentration of 5,894.82 ± 586.48 and 3,363.02 ± 71.14 mg NEQ kgdw-1 and a total phenolic content of 2,143.25 ± 155.17 and 1,605.92 ± 66.46 mg GAE kgdw-1, respectively. With 781.2 ± 112.66 and 718.25 ± 54.89 mg NEQ kgdw-1 the compound neophytadiene was the most common terpene in ethyl acetate and 2-MTHF extracts, respectively. It can be concluded that vegetative tomato plant residues contain a high variety of bioactive molecules. Green solvents, such as 2-MTHF and ethyl acetate, enhance the extraction of these molecules from the solid matrix.
Graphic Memoir Creation for Reconstructing the Dementia Narrative While Reducing Depression and Anxiety Associated Burnout in Informal Dementia Home Caregiving
Authors: Nash Carol
Published: June 2024

Informal dementia home caregiving is viewed negatively and can result in caregiver depression and anxiety from burnout, potentially compromising caregiving. Solutions are unclear, as caregiving relationships are unique—caregiver creation of a graphic memoir may help to mitigate the negative dementia narrative and reduce experienced burnout. This investigation examines the writing of a graphic memoir by one informal dementia home caregiver, created with the help of a cartoon illustrator and a publisher who edited, printed, and made the graphic memoir available at the psychiatric bookstore considered the largest in North America. Mother of the illustrator and the editor and publisher of this graphic memoir, this author provides the perspective taken in this investigation. The analysis, developed by this author, represents psychoanalytic narrative research, serving as the historical method. Aided by email threads between the publisher/caregiver, publisher/printer, and publisher/bookseller, and a published interview with the dementia caregiver are answers to how writing, illustrating, and publishing the graphic memoir affected the caregiver’s narrative reconstruction and burnout. Providing an example for other informal dementia home caregivers similarly to write and illustrate a publishable graphic memoir for their positive narrative reconstruction and to help decrease their depression and anxiety from burnout is the aim.
Arbuscular Mycorrhizal Fungi as Biostimulant and /or Biocontrol Agents? A Review
Authors: Delaeter Mathieu , Magnin-Robert Maryline , Randoux Béatrice , Lounès - Hadj Sahraoui Anissa
Published: June 2024

Arbuscular mycorrhizal fungi (AMF) are soil microorganisms living in symbiosis with most terrestrial plants. They are known to improve plant tolerance to numerous abiotic and biotic stresses through the systemic induction of resistance mechanisms. With the aim of developing a more sustainable agriculture, reducing the use of chemical inputs is becoming of a major concern. After providing an overview on the AMF history, phylogeny, development cycle and the symbiosis benefits, the current review aims at exploring the potential of AMF as biostimulants and/or biocontrol agents. Nowadays, AMF inoculums are already increasingly used as biostimulants, improving mineral nutrient plant acquisition. However, their role as promising tool into the biocontrol market, as alternative to chemical phytosanitary products, is underexplored and discussed. Thus, in the current review, we will address the mechanisms of mycorrhized plant resistance to biotic stresses induced by AMF, and highlight the various factors in favor of inoculum application, but also the challenges that remain to be overcame.

Published: June 2024

The goal of this study is to create regression models estimating the daily Penman–Monteith reference evapotranspiration (PMR) using latitude–temperature data for the state of Sinaloa, Mexico. Daily series of minimum–maximum temperature (1979–2017) were obtained from seven weather stations in Sinaloa. The reference evapotranspiration was calculated by the methods of Penman–Monteith using empirical equations (PMC), Hargreaves (HAC), and PMR. Prior to calculating PMC, the incident solar radiation (SR) was calculated. From the Acaponeta station (2005–2008, 2011–2013 and 2015–2017), all complete observed variables were obtained: mean temperature, incident solar radiation (SRg), average relative humidity and average wind speed at a height of 10 m. The data from the eight weather stations were provided by the National Meteorological Service and the National Water Commission. The daily observed Penman–Monteith reference evapotranspiration (PMO) was calculated. For validation, three simple linear regressions (SLR) were applied: SR vs SRg, PMC vs PMO and PMR vs PMO. hypothesis tests were applied to each SLR: Pearson correlation (Pr) vs critical Pearson correlation (Pcr). All rP were significantly different from zero (> |0.576|): SRg vs SR (Pr = 0.951), PMC vs PMO (Pr = 0.592), and PMR vs PMO (Pr = 0.625). This study provides new models that can motivate and support the design and implementation of intelligent irrigation in the state considered “the breadbasket of Mexico.”

The mystery phenomenon of fungal bioluminescence has always captivated human curiosity, although more attempts need to be made, particularly to bring the new species to the surface. In this study, we devoted considerable space to the taxonomy of these fungi while discussing their biogeography, evolution, bioluminescence mechanism, and potential ecological roles. We provide a detailed explanation of how these fungi produce light, including the role of the enzyme luciferase and luciferin. We also discussed their applications. Here, we presented an updated list of 122 bioluminescent fungi identified from five distinct evolutionary lineages viz. Armillaria, Eoscyphella, Lucentipes, Mycenoid, and Omphalotus worldwide, mainly in tropical and subtropical areas. The bioluminescent fungi descended from the last common ancestor of the mycenoid and the marasmioid clades of Agaricales, which have been maintained for at least 160 million years of evolution. We highlighted the need for further research to understand the ecological role of bioluminescent fungi. Applying bioluminescent fungi in various areas (e.g., environmental and medicinal) demonstrates their validity.

(1) Background: Hepatitis B virus (HBV) sequencing data are important for monitoring HBV evolution. We aimed to molecularly characterize HBV sequences from participants with HBV surface antigen (HBsAg+) positive serology and occult hepatitis B infection (OBI+). (2) Methods: We utilized archived plasma samples from a cohort of people living with (PLWH) in Botswana. HBV DNA was sequenced, genotyped and analyzed for mutations. We compared mutations from study sequences to those from previously generated HBV sequences in Botswana. The impact of OBI-associated mutations on protein function was assessed using the Protein Variation Effect Analyzer. (3) Results: Sequencing success was higher in HBsAg+ than OBI+ samples [86/128 (67.2%) vs 21/71 (29.2%)]. Overall, 93.5% (100/107) sequences were genotype A1, 2.8% (3/107) were D3 and 3.7% (4/107) were E. We identified 13 escape mutations in 18/90 (20%) sequences with HBsAg coverage, with K122R having the highest frequency. The mutational profile of current sequences differed from previous Botswana HBV sequences, suggesting possible mutational changes over-time. Mutations deemed to have an impact on protein function were tpQ6H, surfaceV194A and preCW28L. (4) Conclusions: We characterized HBV sequences from PLWH in Botswana. Escape mutations were prevalent and were not associated with OBI. Longitudinal HBV studies are needed to investigate HBV natural evolution.

Duchenne muscular dystrophy (DMD) is the most prevalent progressive muscular dystrophy, and the guidelines recommend the regular assessment of respiratory muscle function. This study aimed to assess the relationship between maximum inspiratory pressure (MIP), maximum expiratory pressure (MEP) and sniff nasal inspiratory pressure (SNIP) measurements and upright-supine spirometry parameters in children with DMD, predictability of upright-supine spirometry in terms of diaphragm involvement, and impact of nutrition on muscle strength. This prospective cross-sectional study examined patients with DMD by comparing upright and supine FVC, MIP, MEP, and SNIP measurements. Forty-four patients were included in the study. The mean patient age was 10.8±2.9 years. Twenty-five patients were ambulatory. A significant decrease in FVC, FEV1, and FEF25-75 values was detected in the supine position in both ambulatory and nonambulatory patients (p<0.05). All patients had low MIP, MEP, and SNIP measurements (less than 60 cm H2O). MIP, MEP, and SNIP values were significantly lower in patients with malnutrition than in those without (p<0.05). To accurately assess respiratory muscle strength, supine FVC should be combined with upright FVC, MIP, MEP, and SNIP measurements. It is crucial to regularly screen patients for malnutrition, as this can significantly affect respiratory muscle function during pulmonology follow-up.

This study evaluates the R3THA™ technology-supported assessment protocol for home-based rehabilitation in children with cerebral palsy (CP). It focuses on the reliability and validity of R3THA™ in assessing hand and arm function, comparing kinematic assessments with standard clinical assessments. Conducted during a 4-week summer camp, the study involved children with CP aged 3-18, assessing their functional and impairment levels. The findings suggest that R3THA™ is more reliable for children aged 8 and older, indicating that age significantly influences the protocol's effectiveness. Results also showed that R3THA-AP's kinematic measurements of hand and wrist movements were positively correlated with the Box and Blocks Test Index (BBTI), reflecting hand function and dexterity. Additionally, R3THA-AP's accuracy metrics for hand and wrist activities aligned with the Melbourne Assessment 2's Range of Motion (MA2-ROM) scores, suggesting a meaningful relationship between R3THA-AP data and clinical assessments of motor skills. However, no significant correlations were observed between R3THA-AP and MA2's accuracy and dexterity measures, indicating areas for further research. These findings validate R3THA-AP's utility in assessing motor abilities in CP, supporting its integration into clinical practice.

Studying models of healthy aging and exceptional longevity is crucial to understand a possible longevity signature as most of them show resistance to age-related diseases. In particular, semi- and supercentenarians are a highly selected group, having survived significant adversities, including the Spanish Flu and COVID-19 pandemics, indicating distinctive immune system characteristics. This paper analyse the inflammatory scores (INFLA-score, Systemic Inflammation Response Index (SIRI)) and Aging-Related Immune Phenotype (ARIP) indicators calculated from the dataset of the DESIGN project, including 249 participants aged 19-111 years, trying to understand the immune-inflammatory (IMFLAM) role to achieve longevity. Statistical analyses, including linear regression and one-way ANOVA, were performed to explore the correlations between these parameters and age. Both INFLA-score and SIRI showed a significant increase with age. However, no statistical difference is observed when analysing the values for semi- and supercentenarians with those for other age groups, whose values are similar to that of adults and less than younger centenariansRegarding ARIP values, it is noteworthy that when comparing the CD8 Naive/Effector scores between groups, no significant differences were observed between the semi- and supercentenarian group and the other groups. These results support the idea that the control of IMFLAM response can promote extreme longevity.

Ruminant animals naturally emit methane gas owing to anaerobic microbial fermentation in the rumen, and these gases are considered major contributors to global warming. Scientists worldwide are attempting to minimize methane emissions from ruminant animals. Some of these attempts include the manipulation of rumen microbes using antibiotics, synthetic chemicals, dietary interventions, probiotics, propionate enhancers, stimulation of acetogens, manipulation of rumination time, vaccination, and genetic selection of animals that produce low methane (CH4). The majority of synthetic additives are harmful to both beneficial rumen microbes and the host or only temporarily affect methanogenesis. Phytogenic feed additives (PFAs) have recently emerged as the best alternatives to antibiotics and synthetic chemicals because of growing public concerns regarding drug resistance and the negative impacts of antibiotics and synthetic chemicals on humans, livestock, and the environment. These additives reduce methane production and improve the volatile fatty acid profile. In this review, we provide an overview of PFA sources and how their bioactive components affect the rumen microbiome to reduce methane emissions. Additionally, we highlight the mechanisms of action of PFAs as a whole as well as some of their bioactive components.
