Efficacy and Cytocompatibility of a Pressure Garment—Silicone Composite Dressing Material for Scar Healing

Pressure garment therapy (PGT) and silicone gel sheeting (SGS) predominate non-invasive interventions for burn injuries, but the market lacks a composite solution combining pressure garment fabric (PGF) and medical-grade silicone (e.g. Biopor®AB) for multi-therapeutic efficacy. To address this gap, a versatile composite dressing of PGF-Biopor®AB was developed. PGF-Biopor®AB incorporates dual PGF-SGS therapy, mechanotherapy, and active moisture management, to facilitate recovery of hypertrophic subsidiary structures. The PGF structure enables the application of PGT, while the Biopor®AB silicone characteristics enforce silicone gel therapy (SGT). The PGF-SGS efficacy optimization not only reduces tension but also facilitates water vapor and oxygen penetration, along with hydration of the stratum corneum. Mechanotherapy, involving tension-shielding and pressure redistribution, promotes the reorganization of the collagen-fiber network. For active moisture management, the incorporation of a microchannel structure with active nylon absorbency facilitates effective moisture control through water absorption, retention, and cellular pathways of transport. In this study, the microscale features in the structure were further investigated. Under ISO 10993-5 standard, an over 70% cell viability in 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay containing the L929 cell line verified the enhanced cell growth and inhibited proliferation, endorsing the safe usage of PGF-Biopor®AB. Patient studies of one-month efficacy in both high and low-cell-density samples and an early scarless healed wound suggest that over 70% cell viability is sufficient for optimal scar therapeutics. The multifaceted scar repair roles are fulfilled by addressing persistent inflammation, insufficient oxygenation, low levels of perfusion, and scar-healing tension, hence realising the multi-therapeutic efficacy of the composite dressing.

Proposal for A Systemic Human Ecological Turn for Health Science and Medicine

Industrial development processes, accompanied by extreme growth processes, regards world population, pollution, food production and the exploitation of natural resources have caused severe ecological problems. This has been well known since 1972 through the study ‘The Limits to Growth’, in which humanity and the world society was called upon to make an ecological turn and to change its consumption model and the type of economic development that was not suited to finite natural resources (or a finite planet). However, the relationships between the state of the environment and human health have hardly been considered, although an ecological view of health was already proposed by Hippocrates, and as in the meantime, the technical terms “Environmental Health” and “Environmental Medicine” have become established at universities. It is only in recent times that global terms such as climate medicine, One Health, Eco Health, etc. have become powerful pragmatic and action-oriented initiatives. They can be understood as calls for a worldwide health-related ‘ecologization’ of (health) culture. Regarding these approaches we highlight theoretical and metatheoretical aspects, since in general, any real action is only as good as the analytical quality of the plan that serves as a guide for that action. From this point of view, we find that these approaches exhibit striking weaknesses. These are, among other things: the neglect of epistemological challenges combined with inconsistent conceptualizations of the category environment, the very superficial models of human beings, weaknesses of ecological frameworks in relation to the macro-, meso- and micro-eco-social levels of the targeted topics, and a vague notion of systems methodology. Following on from this, we call for an explicit social-/human-ecological framework (New Viennese School, Australian School) for environmental health issues as it has been established for decades in the field of environmental, sustainability and transformation sciences.

Advancements in the Bio-degradation of Plastic Waste into Value-added Chemicals: A Recent Perspective

Plastics are an essential component of modern life, but the plastic waste has caused significant environmental pollution and economic losses. The effective solution to these problems is the biodegradation and high-value conversion of plastic waste. After biodegradation, plastic waste is broken into smaller molecules and eventually transformed into innocuous substances like water, carbon dioxide and biomass. High-value conversion enables plastic waste to be converted into products with higher economic value and environmental friendliness. Based on this, we summarize the biodegradation methods of bioplastics and analyze the shortage of these methods. Subsequently, we summarize the progress of converting the degradation products into value-added chemicals, comprehensively analyze the advantages and disadvantages of these bioconversion process, and propose some strategies to address these disadvantages. Finally, we analyze the significance of establishing a microbial-based conversion process that integrates the degradation and the conversion, and propose some potential strategies.

The Application of Forensic Imaging to Sex Estimation: Focus on Skull and Pelvic Structures

Forensic imaging is recognized as a vital tool in forensic practice mostly reflected by the wide use of post-mortem imaging in death investigations. With the surge of forensic imaging applications and research in recent years, many forensic subdisciplines have adopted this tool as a scientific investigation method, including forensic anthropology. Sex estimation is one of the key assignments in forensic anthropology along with age, ancestry and stature estimation. Traditionally, this assignment is done with non-metric macroscopic examination and metric analysis performed by forensic anthropologists. Today, forensic imaging serves as an auxiliary tool that adds to traditional methods and brings sex estimation to a dynamic era. The purpose of this article is to review forensic imaging methods in forensic anthropology sex estimation with a focus on skull and pelvic structures, aiming to provide insights into the best practices and prospective research directions. 

Measurement and Structure of Common Prosperity of Urban Residents the Case of Hangzhou, China

Common prosperity is an important feature of the social state that the people of the world aspire to, and an important feature of the Chinese path to modernization. Taking common prosperity as the result of income and assets does not facilitate a full understanding of people’s common prosperity, because common prosperity also includes people’s pursuit of subjective happiness such as happiness and satisfaction. From the perspective of the need for a better life in China, this study constructs a subjective evaluation system of the common prosperity of urban residents, including 5 dimensions and 25 specific indicators. It uses survey data from 460 participants and applies the graded response models to estimate parameters and predict latent variables. We find that 21 indicators are in line with the reasonable range of basic assumptions and parameters. They have a strong ability to distinguish the common prosperity of residents in different regions, but have different functional characteristics. The confirmatory factor analysis shows that the common prosperity index of residents includes four potential factors: income, education, medical care, and old-age care, and ecology, which has a good structural effect. In terms of weight, education, medical care and old-age care are the most important factors influencing common prosperity. Among them, the classification policy of high school entrance examination, the quality and fairness of primary and secondary education, the degree of medical insurance security, and the waste sorting and community security are important aspects of evaluating the Common prosperity of residents. 

Assessing Energy Emissions and Environmental Impact of Wool Processing: A Case Study of an Indian Textile Mill

The objective of this study is to investigate and analyze the effect of varying sources of energy inputs and their impact on carbon emissions during wool fiber processing. The method involved industrial visits to the textile wool processing mill and interaction with the manufacturing as well as commercial sourcing teams to gather relevant data.  The results and outcome of this analysis indicate that wool wet processing is responsible for a significant carbon emission of about 0.031 tCO₂e/unit of production. Coal as a source of energy has the highest carbon emission 0.066 tCO₂e/product, while the use of biomass and Pressurized Natural Gas (PNG) had significantly lower CO₂ emissions. Further, this study evaluated the scope 1 and scope 2 category emissions produced at the wool processing stage which accounted for 56303.2 tCO₂e and 1817.10 tCO₂e respectively. 

Monitoring Complexity in Clean Energy Systems Applications

Clean energy applications often involve systems with technological process monitoring. This supervision aims to optimize operation, in particular efficiency, performance and compatibility with dedicated criteria. Most of these energy systems involve complex procedures. A complex procedure is an arrangement of compound processes interacting in interdependent behaviors. The supervision of these complex procedures focuses on the interaction of compound processes, their digital coupling and the handling of uncertainties in their detection and digital tools. Real-virtual pairs, such as digital twins, could carry out such surveillance. This commentary aims to analyze and illustrate such supervision in clean electromagnetic energy systems based on a review of the literature. The notion of complexity and the interactions of the compound processes involved are first addressed and detailed. The modeling of these interactions is presented through the mathematical coupling of the electromagnetic equations with other equations of the phenomena involved. These phenomena are linked to the functional or environmental behaviors of the systems. Compound process monitoring in complex procedures is then analyzed taking into account threats, unsolicited external events and uncertainties related to the sensing and digital tools involved. This contribution illustrated several points relating to, the relationship between the complexities of a real energy procedure and its coupled virtual model, the dependence of the model reduction strategy on each specific application and the reduction of uncertainties through the matching of real-virtual pairs. The different analyses are supported by literature references permitting more information when necessary.
