HOMMAGE AU MÉDECIN PRINCIPAL HENRI-LOUIS DUPRÉ

Henri-Louis était un camarade hors pair. C’était un médecin militaire investi, attentionné et proche de ses patients. Cet article illustre sa volonté de partager son expérience clinique opérationnelle. C’était un collègue et ami remarquable, doué d’une formidable énergie contagieuse. Jusqu’à son dernier souffle, il nous a éblouis, comme il a su le faire avec naturel durant toute sa trop courte vie. Il s’en est allé bien trop tôt, mais il a laissé une empreinte indélébile, gravée à jamais en chacun de ceux qui ont eu la chance de le côtoyer.
Repose en paix notre Mammouth.

Le Centre médico-chirurgical interarmées Dominique Mattei est une structure accueillant un Role 1 et un Role 2. Elle est dédiée au soutien des forces françaises stationnées à Djibouti. Nous rapportons le cas d’un marin pris en charge dans les suites d’un traumatisme crânien grave. Le patient est admis au Centre médico-chirurgical interarmées dans le coma et en choc hémorragique. Il présente d’emblée des signes d’hypertension intracrânienne. L’imagerie objective la gravité des lésions cérébrales. La télétransmission des images et la discussion avec l’équipe de neurochirurgie de l’Hôpital d'Instruction des armées Percy permettent de poser l’indication de craniectomie en urgence, chirurgie réalisée sur place, par un chirurgien viscéral réserviste. Confronté à la gestion du choc hémorragique et disposant de ressources transfusionnelles limitées, une collecte de sang totale est organisée. Elle permet de fournir les ressources nécessaires à la transfusion massive. Après une réanimation prolongée sur place liée aux difficultés de rapatriement, le patient est transféré vers une structure de soins tertiaire. Cette prise en charge a été rendue possible par l’enseignement CACHIRMEX et le savoir-faire du Service de santé dans l’utilisation du sang total.

Authors: BARBIER Olivier , BILICHTIN Émilie , AMAR Sarah , RACLE Maëlle
Published: March 2023

Introduction : L’évolution actuelle des pratiques en chirurgie se fait de plus en plus vers l’hyperspécialisation. En revanche, en opérations extérieures, les chirurgiens orthopédistes doivent faire face à des pathologies très diverses. Ainsi, une formation spécifique des chirurgiens militaires projetables fut mise en place en 2007. Le but de cette étude était d’évaluer la pertinence de cet enseignement à la vue des pathologies rencontrées au cours des conflits actuels.
Matériel et méthodes : L’activité des chirurgiens orthopédistes déployés sur trois théâtres d’opérations extérieures récents (Afghanistan, Mali, République centrafricaine) a été rétrospectivement analysée et comparée aux enseignements délivrés.
Résultats : Cette étude montrait une grande variabilité des interventions réalisées en fonction des théâtres d’opérations. De nombreux actes non orthopédiques comme des réparations vasculaires et des craniectomies décompressives ont aussi été réalisés. Le traitement de l’ensemble des pathologies rencontrées avait été enseigné durant la formation initiale.
Discussion : La formation initiale des chirurgiens orthopédistes semble adaptée aux pathologies et traumatismes rencontrés sur les théâtres d’opérations actuels. L’enjeu est ensuite d'assurer le maintien de ces compétences techniques entre chaque mission par la formation continue.

La reprise d’activité d’un militaire après un syndrome coronaire aigu (SCA) nécessite une évaluation de son état de santé qui s’effectue au cours de la visite médicale de reprise en antenne médicale. Au sein des forces, le médecin du service de santé des armées occupe une place centrale dans le parcours de soins. Il effectue cette évaluation selon les pratiques conformes aux recommandations. Nous abordons les éléments à rechercher lors de cette visite réglementaire, les mesures de prévention secondaire à mettre en œuvre afin de limiter le risque de récidive, puis les consignes données par les instructions concernant l’aptitude médico-militaire.

Authors: Torres Vanderli de Lima Vaz , Batista Josemar
Published: March 2023

OBJETIVO: conhecer a percepção de estudantes de enfermagem em relação à identificação e manejo de pacientes com reações transfusionais imediatas. MÉTODO: descritivo-exploratório de abordagem qualitativa, com aplicação de questionário semiestruturado no mês de junho de 2022 à 15 estudantes de enfermagem numa instituição privada de ensino superior do sul do Brasil. Os dados foram analisados segundo análise de conteúdo, modalidade temática.  RESULTADOS: emergiu a categoria: conhecimento de estudantes de enfermagem em relação às reações transfusionais imediatas, constituída por duas subcategorias: fragilidade conceitual para o reconhecimento precoce de sinais e sintomas de reação transfusional imediata; e condutas gerais e específicas na ocorrência de reação transfusional imediata sob a ótica de estudantes de enfermagem.  Observou-se incipiência conceitual quanto à temporalidade da reação transfusional, e entre os principais sinais e sintomas relatados destacaram-se a dor e a febre. Embora dois participantes não soubessem relatar nenhuma abordagem/conduta inicial, observou-se que suspender a transfusão imediatamente, solicitar avaliação médica e verificar os sinais vitais foram preponderantes nos depoimentos. CONCLUSÃO: os estudantes de enfermagem apresentam desconhecimento conceitual sobre reações transfusionais, e reconhecem as alterações mais comuns e imediatas indicativas das transfusões, de modo a elencar condutas a serem instituídas pelos profissionais de saúde para minimizar os impactos desses agravos aos pacientes.
Experimental and theoretical studies of the influence of the bench elements on the transient operation of the turbine
Authors: AF Salnikov , SV Bochkarev , IA Zubko
Published: March 2023

The energy parameters obtained during the tests of turbines of power units on the stand differ from those in the product. The research data, which results are presented in the materials of the paper, are aimed at analyzing the discrepancies between the parametric indicators of power units and bench tests of the turbines. The novelty of the obtained results reveals the direct and inverse relationship of changes in the amplitude-frequency characteristics of the elements of the stand (depending on the realized turbine power) with the obtained results of measuring the turbine power on the stand. We developed and described an algorithm for constructing dynamic analysis during the formation of the wave field of the test bench for turbines both in transient modes and in stationary modes corresponding to a constant number of turbine revolutions. It is shown that, by using the algorithm of modal deduction and conditions of dynamic excitation of vibrations from the tested turbine with elements of studying its power, it is possible to construct transients with certain reliability when the number of revolutions of the turbine changes, i.e. its power. The diagnostic model has a novelty since it allows not only to assess of the influence of the elements of the stand on the nature of the transient process when measuring turbine power in transient modes, taking into account the frequency adjustment when changing the revolutions of the turbine and the elements of the stand but also to form requirements for the frequency tuning of the stand. To clarify the transfer function of the "stand–turbine" system, a modal analysis was applied, which made it possible to clarify the structure of the transfer function in the frequency range of the natural (partial) frequencies of the elements of the stand when the restructuring of the wave field during the transient operation of the turbine, but also when the turbine reaches the specified power.

Preparation of 1L of Foraging Medium v1
Authors: Pérez Escudero Alfonso
Published: March 2023

Protocol is mainly inspired from: WormBook Methods http://www.wormbook.org/chapters/www_strainmaintain/strainmaintain.html. This protocol is for making medium for foraging experiments with the worm Caenorhabditis elegans. The medium has the same basis as the standard Nematode Growth Medium (NGM), but contains no peptone (as no long-term worm growth is required for our experiments), and contains antibiotics that prevent our bacterial strains from growing (bacteriostatic concentrations). It describes both medium preparation and pouring.
Bulk in vivo electroporation (single cell) v1
Authors: Suppermpool Anya
Published: March 2023

This protocol will allow you to express single (or near single/mosaic) cell expression in the tectum of larvae. This protocol is adapted from (Hoegler and Horne, 2010; Nikolaou et al., 2015). If you would like to do focal-electroporation (into cell) to trace projections/neurites please see (Henriques et al., 2019) or any older Bianco paper. Electroporation is a way to deliver plasmids or vectors into living embryos. For my experiments, I want to see larvae/neurons at 6-9dpf so I electroporate at 3dpf. But if you wish you do younger see Hoegler (24hpf) - likely that you need to adapt some things as younger larvae are curled and will be more fidget-y. Note: depending on what you want to express/and how much of it, electroporation time may differ. For example, AS wants one-neuron expression which gets roughly 10-30% of electroporated fish (depending on expression see Inject and electroporate section). AS then wants say 15-20 positive embryos => meaning 150-200 embryos electroporated => taking roughly 13:00-17:30/18:00 (5hr) long.

Institutional Linkages Between National Social Health Protection And Occupational Health Services Systems: A Scoping Review v1
Authors: Iradukunda Aurore
Published: March 2023

The impact of globalization and industrialization in the last decade has been characterized by a persistence of informality and an increase in precarious jobs increasing workers’ exposure to occupational health risks. Technological advances and the COVID-19 pandemic have also accelerated participation in the gig and platform economy, giving rise to new forms of employment for which neither national social health protection (SHP) systems nor occupational health services (OHS) are adequately adapted. In many LMICs but also high-income countries, OHS remain bound by the employer-employee relationship, often leaving workers engaged in the informal, platform and gig economies without access to OHS. Similarly, this group remains disproportionately excluded from SHP coverage. Recent evidence has also shown the tendency for national SHP systems and workers to absorb the financial burden of occupational disease, despite the existence of workers’ compensation mechanisms. This signals a preponderance of curative care over preventative care with important financial ramifications for national SHP systems but also for workers who face the financial and health risks of preventable diseases and accidents. The extension of SHP and OHS coverage to workers in all forms of employment is thus a joint priority for both OHS and SHP systems. In this paper, we argue that the establishment of robust interinstitutional linkages can strengthen both systems and extend coverage of both SHP and OHS. Limited evidence of such interinstitutional linkages in countries such as Canada and Finland supports this argument. However, limited evidence exists elsewhere, particularly in LMICs. This scoping review aims to document existing institutional linkages between SHP and OHS systems globally. To do so, it asks: 1) In which countries can we identify interinstitutional linkages? and 2) What is the nature of such linkages? This study is based on the scoping methodology of Arksey and O’Malley. Relevant databases and grey literature will be searched using a search strategy developed by a librarian at Université de Laval. A double-blind selection of papers will be conducted based on defined inclusion and exclusion criteria. Finally, deductive thematic synthesis is used to present the results and a typology of linkages is developed. To the best of our knowledge, this study is the first to provide a systematic mapping of interinstitutional linkages between OHS and SHP systems globally. A better understanding of such linkages will allow for the documentation of best practices that can guide the strengthening of both systems in the face of current global crises.

The new CIADS dossier on reproductive rights and women's health aims to bring together scientific contributions from national and international researchers with approaches related to the normative and bioethical shaping of reproductive health. To deepen the discussion, we have sought to consider issues related to access to reproductive health, the plurality of parental projects, freedom over one's own body, medically assisted reproduction, and the contraceptive situation that can lead to interruption of reproductive planning.
O estado regulatório da reprodução humana assistida no Brasil: da ausência de legislação ordinária ao regulamento deontológico atual
Authors: Araújo Ana Thereza Meirelles
Published: March 2023

Objective: to analyze the legislation and deontological rules in force in Brazil regarding artificial insemination in humans, considering the impact on the rights of those involved. Methods: bibliographic and documentary study using the deductive method, with the aim of critically commenting on the current state of legislation on artificial insemination in humans. Results: the legal framework includes general normative provisions related to the Civil Code, the Biosafety Law and deontological provisions. Together, they provide relevant content but are sometimes insufficient and inadequate for the various circumstances that may be associated with the practice of in vitro fertilization, surrogacy, and postmortem reproduction. Conclusion: based on women's reproductive rights and the autonomy of the parties, it is proposed to reconsider some of the contents regulated in the deontological provisions and to update the legislation.

Os direitos sexuais e reprodutivos da mulher no Brasil na perspectiva do feminismo decolonial
Authors: Souza Iara Antunes de
Published: March 2023

Objective: to analyze the sexual and reproductive rights of women in Brazil from the perspective of decolonial feminism. Methods: it was a theoretical-dogmatic investigation that aimed to outline, based on legal norms, the sexual and reproductive rights of women and to show these rights, considering intersections, as obstacles to the recognition and exercise of these rights in a decolonial perspective. Results: legal norms were found to be inadequate in hegemonic ways, as socioeconomic and legal issues prevent their implementation for all women. Conclusion: intersectional and diversity factors prevent the exercise of women's sexual and reproductive rights in Brazil, making legal norms insufficient to guarantee rights.

Published: March 2023

A modelagem computacional e otimização no campo dos processos industriais, mais precisamente relacionados à pirólise de biomassa, podem auxiliar na determinação das melhores condições operacionais de processamento, além de contribuir com a demanda crescente de energia com sustentabilidade ambiental. Nesse contexto, o objetivo deste trabalho foi a implementação de técnicas de otimização para ajuste de parâmetros cinéticos e a aplicação de um modelo matemático fenomenológico visando descrever o comportamento dinâmico da pirólise para as biomassas Carvalho (Quercus sp.) e Tauari (Couratari sp.). Para essa finalidade, empregou-se o software livre Scilab, linguagem de programação de alto nível, orientada à análise numérica, computação científica e testes estatísticos paramétricos. Os resultados mostraram que o modelo foi confiável quando comparado com dados experimentais da literatura para o Carvalho e com os coletados através de experimentos realizados em laboratório para o Tauari. A aplicação da análise da variância (ANOVA) mostrou que o valor de F calculado variou de 2294,0248 a 41,6304 sendo maior que o F tabelado ao nível de significância de 5% (0,0043 e 4,1055), o que demonstra que o modelo é adequado para predizer o comportamento da pirólise das biomassas nas condições operacionais simuladas.

Authors: Ferraz Mikael de Souza , Mota José Hortêncio
Published: March 2023

A cenoura é a principal hortaliça de raiz em valor econômico e se encontra entre as dez espécies de olerícolas mais cultivadas no Brasil. Este estudo teve como objetivo avaliar a produtividade e a qualidade comercial de raízes de cenoura submetidas a diferentes níveis de superfosfato simples (0, 100, 200 e 300 kg ha-1 de P2O5) e cloreto de potássio (0, 100, 200 e 300 kg ha-1 de K2O) que foram aplicados na superfície do canteiro e incorporados com enxada. O delineamento utilizado foi o de blocos ao acaso em esquema fatorial 4x4, com quatro repetições. As variáveis analisadas foram produtividade total e de raízes comerciais, diâmetro e comprimento de raízes comerciais. Não ocorreu interação significativa (p < 0,05) entre as doses de fósforo e potássio para as variáveis avaliadas. As doses de fósforo e potássio foram significativas apenas para produtividade total e de raízes comerciais, sendo que a máxima produtividade de raízes comerciais foi obtida com a dose de 255,8 kg ha-1 de P2O5 (39,5 t ha-1) e de 174,0 kg ha-1 de K2O (37,6 t ha-1). O incremento de produtividade foi, em média, 49,5% com dose de fósforo e de 31,6% com dose de potássio superior em relação à ausência de adubação, demonstrando a importância do manejo adequado de adubação fosfatada e potássica na cenoura para a obtenção de elevadas produtividades.
Epífitas vasculares ocorrem próximas de corpos d’água na Estação Ecológica da Serra das Araras

Published: March 2023

Epífitas vasculares são plantas que se desenvolvem sobre outras espécies vegetais e são consideradas bioindicadoras de qualidade ambiental. O presente estudo objetivou realizar um levantamento de epífitas na Estação Ecológica Serra das Araras, localizada no bioma Cerrado em uma área de transição com Amazônia e Pantanal, avaliando o potencial das espécies encontradas como bioindicadoras de umidade. Foram dispostos três transectos, paralelos ao córrego Camarinha e com proximidade do córrego Miranda, ambos inseridos na Bacia do Alto Paraguai, com dez parcelas em cada, totalizando 30 parcelas de 10 x 3 metros. Foi realizada a análise de variância (kuskall-wallis) da abundância entre os transectos, análise de regressão linear com os dados de abundância e riqueza em função da distância dos corpos d’água e análise de densidade de Kernel. Foram registradas seis espécies de epífitas, com destaque para Phlebodium decumanum (Willd.) J.Sm. e Vanilla sp., sendo que 19,6% dos 143 forófitos amostrados foram confirmados com presença de epífitas e, destes, 27 são Attalea speciosa Mart. ex Spreng. O transecto mais próximo dos corpos d’água apresentou abundância com diferença significativa (p = 0,004) do transecto três. Das 30 parcelas amostradas, 15 tiveram a presença de espécies epifíticas e a análise de regressão apontou diminuição significativa para riqueza (p = 0,0003, R-ajustado = 0,372) e abundância (p = 0,042 R-ajustado = 0,139) em função da distância dos córregos, o que foi ao encontro do observado na análise de densidade, que apresentou maior concentração próximo dos cursos de água. O histórico de antropização da área pode ter acondicionado uma baixa riqueza de epífitas e a ocorrência dessas espécies está correlacionada com a do forófito de Attalea speciosa estabelecidos preferencialmente em áreas com presença de umidade, podendo, portanto, as epífitas serem bioindicadoras dessa condição ambiental na região.

Authors: Correa Amanda Ribeiro , Arantes Cárita Rodrigues de Aquino , Camili Elisangela Clarete , Guimarães Sebastião Carneiro
Published: March 2023

Portulaca oleracea L., known as purslane, is an unconventional food plant rich in nutrients and medicinal properties, with potential for consumption and commercialization. The objective was to describe phenological stages of purslane based on BBCH (Biologische Bundesantalt, Bundessortenamt and Chemische Industrie) scale and thermal sum at different times. Evaluations were made from two genotypes, the Golden variety and an access. Plants were observed during six consecutive periods, interspersed every two months. Thermal sum and base temperature were obtained considering the average temperature from seedling emergence to flowering and dispersion of the first capsule in 50% of the plants. The phenological cycle of Purslane based on the BBCH scale shows seven main stages, subdivided into secondary stages: germination (0); leaf development on the main branch (1); development of lateral branches (2); development of flower buds (5); flowering (6); seed dispersal (8); and senescence (9). The lower base temperatures (Tb) determined to flowering were 10 to 15 ºC for the variety Golden and access, respectively, since for seed dispersal, Tb was 9 and 13 ºC, respectively. Thermal requirements for Golden variety are 421.3 GD for flowering and 644.2 GD for seed dispersal, while for access they are 239.7 and 407.0 GD, respectively. Purslane as a food plant can be produced throughout the year in tropical region and may be best used if harvested until the plants reach 12 or 10 leaves.

Diffuse large B-cell lymphoma (DLBCL) is the most common variant of non-Hodgkins lymphoma and accounts for 3060% of all non-Hodgkins lymphomas, with increasing incidence increases with age. Currently, the prognosis is assessed using the International Prognostic Index. In recent years, in all European regions, there has been a significant improvement in survival in DLBCL due to the addition of rituximab to standard chemotherapy (CHOP protocol). However, despite significant advances in treatment, long-term remission is only achieved in half of the patients. Laryngeal lesions with this variant of lymphomas is described only in a few articles. There is evidence of various chemotherapeutic regimens effective in this type of lymphoma; in some publications, the authors suggest the use of radiation therapy.
The article presents a clinical case of successful treatment of a patient (chemotherapy + radiation therapy) with diffuse large B-cell lymphoma with laryngeal involvement. with resulting remission. In addition, a review of the literature describing the most common types of lymphomas is presented. The authors set a goal to raise the awareness of physicians about a rare histological variant of laryngeal tumors with a rapid increase in clinical manifestations and the development of life-threatening conditions.
Optimal Multichannel Stretch Factors for Estimating Changes in Seismic Velocity: Application to the 2012 Mw 7.8 Haida Gwaii Earthquake
Authors: Merrill Reid J. , Bostock Michael G. , Peacock Simon M. , Chapman David S.
Published: March 2023

We propose new methods for assessing temporal changes in seismic velocity using the S-wave coda for repeating earthquakes and cross-correlation functions of ambient noise. For a pair of seismic waveforms representing a common source–receiver path, the relative change in path-averaged velocity over the corresponding time interval is directly proportional to the factor by which one waveform needs to be stretched or compressed with respect to the other to achieve maximum coherence. For an arbitrary number of waveforms, initial pair-wise stretch factors determined through standard approaches can be improved through solution of an overdetermined system and further refined through an iterative approach exploiting the singular value decomposition to minimize rank of the stretched waveform section. We apply this combined approach to both repeating earthquakes and ambient noise correlations for Haida Gwaii in western Canada, the site of a Mw 7.8 thrust earthquake in 2012. Optimal stretch factors for repeating earthquake families indicate that path-averaged S velocities dropped by up to 0.16% after the earthquake. Ambient noise correlations indicate that velocities dropped by between 0.26% and 0.39%, which we interpret to be more pronounced in the uppermost levels of the crust. We explore these results in terms of changes in crustal porosity and hydrogeologic conditions by considering the observation that hot spring activity on Haida Gwaii ceased following the 2012 mainshock and recovered over the next several years.

Published: March 2023

Hearing impairment students have limited vocabulary and have difficulty understanding abstract terms, which affects learning the concept of a plane solid figure that they know at school. Deaf students tend to have difficulty perceiving objects from a certain point of view and understanding the relationship between these objects in a particular space. These difficulties affect students' spatial abilities and require special handling in the form of learning-oriented to the learning process, not learning outcomes. The learning process itself can be determined by information systems such as the basis of cybernetic theory and supported by information technology-based interactive learning media. Therefore, this study aims to develop augmented reality media based on cybernetic learning theory to stimulate valid and practical spatial abilities of deaf students. The research and development model carried out in this study is the Borg and Gall model, which has systematic and descriptive steps for practical problems in teaching through applied research. Researchers collected data through validation questionnaires and student response questionnaires. Data analysis was carried out qualitatively and quantitatively. The augmented reality media developed here can be said to meet the criteria of validity and practicality based on the results of the product feasibility test. This media has also proven to be a solution in helping teachers to stimulate the spatial abilities of deaf students through a meaningful learning process determined by a technology-assisted information system

Staphylococcus aureus is a facultative anaerobe and catalase-positive bacterium responsible for various skin infections and life-threatening problems, including bacteremia and pneumonia. This bacterium produces a bunch of superantigens in the blood called enterotoxin. This toxin is responsible for food poisoning and toxic shock syndrome. Moreover, Bovine mastitis is also associated with S. aureus. Further, S. aureus related to drug resistance makes the infection more dreadful. Now a day, various natural compounds such as phytochemicals are gaining importance as they are effective against many diseases, including S. aureus infections. The present study used molecular docking of three ligands, i.e., Kaempferol, Apigenin, and Quercetin, with enterotoxin A from S. aureus. The docking study revealed that the binding energy of ligands with receptors was -6.6 to -6.9 Kcal/mol. Kaempferol had the highest binding affinity of -6.9 Kcal/mol, suggesting it has a potential against S. aureus. Therefore, in the current research, we have tried to identify occurring compounds that might be used to develop an effective anti-S.aureus agent. The findings are encouraging and will aid researchers in creating new mastitis-fighting medications based on natural phytochemicals.

This present study evaluated the plasmid incidence in bacteria and their genetic elements in heavy metals tolerant-antibiotics resistant microbes isolated from petroleum hydrocarbon polluted sites. The plasmid isolation was carried out using the fermentas Genejet plasmid miniprep kit (Thermofisher Scientific Inc, USA). Screening for class 1, 2, and 3 integrons, incompatibility group P testing, plasmid replicon typing, plasmid restriction analysis, and other analysis was performed using standard laboratory procedures. Plasmid incidences were higher among multiple heavy metal-tolerant bacterial species from hydrocarbon-polluted sites than those from the pristine site. Further, Class 1 integron incidence was significantly higher among the integrons in heavy metal tolerant bacterial isolates isolated from the polluted ecosystems than those from pristine ecosystems. Plasmid replicon type of bacteria with multiple heavy metal tolerance and antibiotics resistance indexes revealed that IncN plasmid replicon type carrying class 1 integron. This encodes resistance to sulphamethazole/trimethoprim, ampicillin, and tolerance to Cd, Ni, and Cu in Klebsiella pneumoniae isolate from petroleum-polluted soil. This is the first report of IncN plasmid in environmental bacteria in Nigeria, particularly from petroleum polluted environment. The conjugation experiment confirmed the possible transferability of antibiotic resistance determinants among isolates in polluted ecosystems. From the results of this study, it can be concluded that petroleum hydrocarbon pollution vis-a-vis heavy metal selective pressure with the abundance of mobile genetic elements amongst isolates from polluted ecosystems could contribute to the dispersing of antibiotic resistance genes, thus posing a serious public health concern.

Tropical peat is an important natural ecosystem, and its natural state plays an important role in climate regulation. These peatlands globally provide vital environmental benefits, especially in case of their enormous carbon storage potential. Peat land also functions as a source of livelihood for the community, especially for agricultural activities, and this will lead to the potential loss of carbon stock in peatlands. This study examines plants' potential to create Carbon to offset carbon dioxide emissions and different land use types. The study focused on Central and West Kalimantan, Indonesia. Peat soil samples were collected from various types of land from 0-15, 15-45, and 45-100 cm depth and analyzed for physical and chemical parameters. The cylinder chamber method with infrared gas analysis model EGM-4 was used to measure CO2 emissions. Plant carbon sequestration was measured in a 6.25 m2 plot in the study sites of Central Kalimantan. The study showed that type of commodity and period of management affect the carbon content in peat with different land uses, and it is affected by soil bulk density, organic matter content, and CO2 emission. In the case of study crops, oil palm, rubber, corn, and mustard emit the highest CO2. Further, corn crop has the highest potential to fix carbon dioxide and produces more Carbon per hectare than the Carbon emitted from corn-planted under peatland conditions. The study indicated that the type of commodity and the time of its management affected the carbon content in peat with different land uses, and carbon content got the change with soil bulk density and soil organic matter content.

L-Asparaginase (L-ASNase) is a crucial anti-tumour drug used to cure acute lymphocytic leukaemia. The current study aimed to enhance the production medium for the endophytic fungus Curvularia sp. LCJ413 that showed significant L-ASNase activity. L-ASNase production from Curvularia sp. LCJ413 was examined in six different media to select an appropriate liquid medium. Among the various media tested, Modified Czapek Dox broth (MCDB) exhibited the maximum L-ASNase activity (8.81 ± 0.52 U/mL). Physical (pH and temperature) and nutritional (carbon, nitrogen, inducer, and their concentrations) parameters were also optimized to boost L-ASNase production. Results of the study suggested a temperature of 28°C at pH 7 with 2 g/L maltose, 10 g/L L-Asparagine, and 25 g/L ammonium sulphate as the optimal carbon, inducer, and nitrogen source resulted in a high L-ASNase activity of 18.9 ± 0.40 U/mL. The statistical enhancement of L-ASNase by Response Surface Methodology (RSM) produced 20.11 U/mL of L-ASNase, which was 2.2 fold higher than the non-optimized medium. This is the first study on L-ASNase production from the endophytic Curvularia sp. LCJ413 isolated from Vitex negundo medicinal plant. Continuous fermentation with the medium composition provided in the study can produce L-ASNase on a large scale.
