Preface

The Second Edition of the International Congress on: Environment and Natural Resources: Challenges and Solutions (ENRSC2023) 30-31th, May 2023, Khenifra, Morocco About the ENRSC2023 Anthropogenic activities have progressed considerably over the last century, especially after the 1950s. The growth of the world population, industrialization, new technologies, the extension of agricultural activities at all levels due to the growing needs of the world population, the overexploitation of natural resources in different environments, etc., have been and remain the driving force behind an unbalanced model of development that has a negative impact on the environment and on natural resources. Indeed, the world is currently facing challenges at all scales, from micro- to macro-environmental issues. The serious challenges to be taken up are major concerning all physical environments - air, soil, and water. The degradation of habitats by various anthropogenic and/or natural activities has a direct impact on biodiversity and consequently on socio-economic development. The International Conference on Environment & Natural Resources: Challenges and Solutions allowed scientists from different universities and institutes to exchange and debate different themes on the environment and natural resources, their challenges, and probable solutions to reduce the environmental impact and suggest better natural resources management practices. Finally, the current global context proves to us, every day, that we must contribute each from one’s position to the mitigation of negative impacts, and that the urgency is to set up concrete and sustainable-integrated actions. After the success of the first edition of the International Congress: Environment and Natural Resources: Challenges and Solutions (ENRSC2021), the coordinating committee has decided to organise the second edition of the Congress 30-31th, May 2023.

An improved high-resolution method for quantitative separation of empty and filled AAV8 capsids by strong anion exchange HPLC.

Cell and gene therapy (CGT) is a field of therapeutic medicine that aims to treat, prevent, and cure diseases using engineered cells (stem cells, immune cells, and differentiated adult or fetal cells), vectors [Adeno Associated Virus (AAV), Adeno Virus (AV), Herpes Simplex Virus (HSV), Baculo Virus (BV), Lenti Virus (LV), Retro Virus (RV), etc.], and other carriers [non-viral vectors, virus-like particles (VLP), Lipid Nano-Particles (LNP), etc.]. Among viral CGT vectors, adeno-associated viruses and lentiviruses (AAV and LV) are the most widely applied vector platforms. The presence of non-functional (empty or non-infectious) vectors that carry null or partial genes in the final drug product is classified as an impurity by the FDA. These impurities impair dosage accuracy and induce non-specific immunogenicity and variability in drug efficacy. These non-functional viral vectors in the drug product need to be elucidated following International Conference on Harmonization (ICH) guidelines for clinical manufacturing of the final drug product. This article showcases an ion-exchange chromatography (IEX) high-resolution method supporting ICH guidelines using commercially available AAV8 filled and empty capsids as reference standards. Our method successfully separated empty to full capsids with a resolution of 15 and sustained a linearity greater than 0.98 even under a wide range of empty or full viral particle concentrations (E+9 to E+13 vp/mL), which is an upgrade to other IEX capsid separation methods. The medium-throughput capacity and shorter sample processing time improve testing efficiency and save costs while delivering quality as value. The discussed method is a reliable and reproducible platform to precisely evaluate the presence of non-functional viral particles in AAV8 samples. Aligned with other orthogonal results, the method is a powerful tool to improve the quality of rAAV analytics.

Preface

The International Conference on Natural Resources and Environmental Conservation (ICNREC) is an annual event dedicated to discussing various topics and issues regarding the conservation of natural resources and the environment. The 4th ICNREC was held on October 26, 2023, at the IPB International Convention Center (Botani Square) in Bogor, Indonesia. This year, the conference raised the theme: “Origin of Land Status, History of Land Use, and Development of Plantation Land Cover.” Over the past 25 years, driven by its high economic value, the area of oil palm plantations in Indonesia has nearly tripled. Since 2008, Indonesia has been the largest palm oil producer in the world, contributing 48% of the total global palm oil production. With an area of no less than 16.32 million hectares, palm oil plantations have brought various positive impacts, including generating foreign exchange, alleviating rural poverty, and creating jobs for approximately 21.49 million people. However, this success has also drawn accusations that oil palm plantations originate from primary or secondary forests, leading to deforestation, biodiversity loss, and a decline in plant diversity. Although these accusations are still debatable and not scientifically valid, they have significantly harmed Indonesia’s position in global trade. On May 16, 2023, the European Union officially implemented the European Union Deforestation-free Regulation (EUDR), which aims to ensure that products entering the EU market come from legal sources and do not cause deforestation. This regulation requires companies to trace these commodities back to the land where they were produced. In response, there is an urgent need to develop a scientifically valid and internationally recognized Deforestation Verification or Certification System for every oil palm plantation and palm oil mill. Research collaborations have shown that data and information about the “Origin of Land Status, History of Land Use, and Development of Plantation Land Cover” in various provinces are relatively easy to obtain and scientifically valid. To achieve both national and international legitimacy, it is necessary to discuss these findings with experts from various parts of the world with relevant disciplines. Therefore, the 4th ICNREC is themed “Origin of Land Status, History of Land Use, and Development of Plantation Land Cover.” Given the strategic position of palm oil as Indonesia’s main foreign exchange source and to avoid systemic negative impacts on the future progress of Indonesia’s palm oil industry, developing a deforestation verification/certification system based on data and information about the origin of land status, land cover development, and land use history is crucial. The 4th ICNREC was organized in partnership with the Center for Study, Advocacy, and Nature Conservation (PUSAKA KALAM), the Faculty of Forestry and Environment of IPB University, and the French Agricultural Research for International Development (CIRAD). It also received support from various sponsors, including the Indonesia Oil Palm Plantation Fund Management Agency (BPDPKS), Sampoerna Agri, the Indonesian Palm Oil Association (GAPKI), Asian Agri, the French Embassy in Indonesia, and the Indonesian Oil Palm Farmers Association (APKASINDO), along with many others who contributed to the event’s success. The conference resulted in a proceeding featuring 23 papers on various aspects of biodiversity. We appreciate all the support received in organizing the conference and preparing the proceedings and hope that these proceedings will benefit many people. Best Regards, Prof, Dr. Ir. Yanto Santosa, DEA Chairman of Committee of The 4th ICNREC List of Committee is available in this Pdf.

Research Priorities in Pediatric Asthma Morbidity: Addressing the Impacts of Systemic Racism on Children with Asthma in the United States. An Official American Thoracic Society Workshop Report.

Background: In the United States, Black and Latino children with asthma are more likely than White children with asthma to require emergency department visits or hospitalizations because of an asthma exacerbation. Although many cite patient-level socioeconomic status and access to health care as primary drivers of disparities, there is an emerging focus on a major root cause of disparities-systemic racism. Current conceptual models of asthma disparities depict the historical and current effects of systemic racism as the foundation for unequal exposures to social determinants of health, environmental exposures, epigenetic factors, and differential healthcare access and quality. These ultimately lead to biologic changes over the life course resulting in asthma morbidity and mortality. Methods: At the 2022 American Thoracic Society International Conference, a diverse panel of experts was assembled to identify gaps and opportunities to address systemic racism in childhood asthma research. Panelists found that to examine and address the impacts of systemic racism on children with asthma, researchers and medical systems that support biomedical research will need to 1) address the current gaps in our understanding of how to conceptualize and characterize the impacts of systemic racism on child health, 2) design research studies that leverage diverse disciplines and engage the communities affected by systemic racism in identifying and designing studies to evaluate interventions that address the racialized system that contributes to disparities in asthma health outcomes, and 3) address funding mechanisms and institutional research practices that will be needed to promote antiracism practices in research and its dissemination. Results: A thorough literature review and expert opinion discussion demonstrated that there are few studies in childhood asthma that identify systemic racism as a root cause of many of the disparities seen in children with asthma. Community engagement and participation in research studies is essential to design interventions to address the racialized system in which patients and families live. Dissemination and implementation studies with an equity lens will provide the multilevel evaluations required to understand the impacts of interventions to address systemic racism and the downstream impacts. To address the impacts of systemic racism and childhood asthma, there needs to be increased training for research teams, funding for studies addressing research that evaluates the impacts of racism, funding for diverse and multidisciplinary research teams including community members, and institutional and financial support of advocating for policy changes based on study findings. Conclusions: Innovative study design, new tools to identify the impacts of systemic racism, community engagement, and improved infrastructure and funding are all needed to support research that will address impacts of systemic racism on childhood asthma outcomes.

Validated high performance thin layer chromatographic method for simultaneous quantification of betulinic acid, β-sitosterol and lupeol in fruits, leaves, root bark and stem bark of Dillenia indica Linn

AbstractDillenia indica is one of the important medicinal plants and is extremely popular in many systems of medicine including ayurvedic, homeopathic, and siddha. Traditionally, different parts of this plant have been used to treat cancer, wound healing, diabetes, diarrhea, bone fractures, abdominal pains, cuts and burns. In the present study, a simple, precise, accurate and validated high performance thin layer chromatographic (HPTLC) method was developed for simultaneous estimation of three pharmaceutically active compounds i.e., betulinic acid (BE), β-sitosterol (BT) and lupeol (LP) in fruits, leaves, root bark and stem bark of D. indica. Standards and plant samples were applied on TLC aluminum plate precoated with 0.2 mm layer of silica gel 60F254. The plate was run in a twin glass chamber comprising toluene:methanol:chloroform (8:1:1, v/v/v) as a mobile phase which resulted in better separation of compounds. The plates were immersed in anisaldehyde-sulfuric reagent and then heated at 105 °C for 5 min in CAMAG TLC plate heater for appearance of bands. Densitometric scanning was performed at λmax = 525 nm using tungsten light source in CAMAG TLC Scanner4 armed with WinCATS software. RF values of BE, BT and LP standards and those of plant samples were found to be 0.38 ± 0.01, 0.54 ± 0.01 and 0.65 ± 0.02 respectively. The method was further validated by following the International Conference of Harmonization (ICH) guidelines. For BE, BT and LP, the linear regression data for the calibration plots revealed a satisfactory linear association with correlation coefficients (r2) = 0.9736, 0.9989 and 0.9957, respectively. Linear ranges for BE, BT and LP were 2,000–6,000 ng/band, 200–1,000 ng/band, and 200–600 ng/band respectively. Accuracy of the method was assessed by recovery study conducted at three different levels with the average recovery of 99.19, 99.69 and 100.95% for BE, BT and LP, respectively. The results exhibited the highest content of BE (0.148 ± 0.01%), BT (0.031 ± 0.01%) and LP (0.047 ± 0.01%) in stem bark. The developed method will be useful for routine and quality control analysis of fruits, leaves, root bark and stem bark of D. indica species.
