The convergence of biotechnology and homeopathy offers a novel perspective on medicine through the integration of molecular precision and holistic care. Biotechnology, informed by systems biology, excels in elucidating biological complexity, while homeopathy prioritizes personalizing treatment with minimal interventions. Historically viewed as contradictory, both disciplines aim to achieve health restoration through targeted natural methods. Recent findings in nanobiology indicate that ultra-dilutions may contain nanoparticles, potentially linking the two fields materially. The amalgamation of biotechnology and homeopathy could facilitate diverse applications, including AI-driven genomic prescriptions, standardization of remedies via nanotechnology, hybrid therapeutics, and modulation of the microbiome and epigenome. Such innovations may enhance preventive and regenerative medicine and foster sustainability through resource-efficient, environmentally friendly solutions. However, challenges persist, necessitating rigorous validation, prevention of misuse, equitable access, and ethical integration of traditional practices. Nonetheless, advancements in systems biology, nanoscience, and AI may herald the advent of Homeo-Biotech Medicine, a scientifically validated, globally accessible, and ecologically sustainable paradigm in the 21st century.

Aim/Background: The declining availability of fossil fuels cannot meet the increasing global energy demands and contributes significantly to greenhouse gas emissions, worsening global warming. Additionally, poor management of organic waste, including livestock and food scraps, poses environmental pollution risks. Anaerobic co-digestion (AnCoD) of livestock waste and food scraps offers a sustainable solution, producing renewable biogas while minimizing ecological impact. This study aims to evaluate whether co-digesting cow manure (CM) with fruit waste (FW) in varying ratios can enhance biogas production and methane quality.

Aim/Background: The declining availability of fossil fuels cannot meet the increasing global energy demands and contributes significantly to greenhouse gas (GHG) emissions, worsening global warming. Additionally, poor management of organic waste, including livestock and food scraps, poses environmental pollution risks. Anaerobic co-digestion (AnCoD) of livestock waste and food scraps offers a sustainable solution, producing renewable biogas while minimizing ecological impact. This study aims to evaluate whether co-digesting cow manure (CM) with fruit waste (FW) in varying ratios can enhance biogas production and methane quality. Methods: This experimental study was conducted using five batch anaerobic digesters (each with a 5 kg capacity) under mesophilic conditions (37°C) over a 14-day retention period. The digesters, labeled Case-1 through Case-5, contained different CM-to-FW ratios: 1:1, 4:1, 1:4, 3:2, and 2:3. Pretreatment of substrates was performed prior to digestion, and critical process parameters such as temperature, pH, and biogas volume were monitored throughout the study. Results: Among all tested ratios, Case-2 (4:1 cow manure to fruit waste) demonstrated the highest biogas yield, achieving a methane concentration of 49%. The results indicated that proper substrate proportioning significantly influences the efficiency of anaerobic digestion. Additionally, the process remained stable under mesophilic conditions, with favorable pH levels throughout the experiment. Conclusion: This study confirms that the anaerobic co-digestion of cow manure and fruit waste under mesophilic conditions is a promising strategy for enhancing biogas production. The findings highlight that substrate composition plays a critical role in determining biogas yield and methane quality.

Environmental nanoparticles have become an area of considerable concern owing to their potential health hazards, particularly for vertebrates subjected to contaminated environments. This review explores the ramifications of these particles on respiratory health, concentrating on their origins, pathways of exposure, and the mechanisms through which they elicit detrimental effects.

Plastic pollution has escalated into a global environmental crisis, with millions of tons of synthetic polymers accumulating within ecosystems and posing significant threats to both biodiversity and human health. Conventional methods of plastic waste management, such as mechanical and chemical recycling, exhibit limitations in terms of sustainability, particularly for polymers such as polyethylene (PE) and polystyrene (PS), which demonstrate a pronounced resistance to degradation. Biotechnological approaches that exploit microbial enzymes and synthetic biology offer a promising alternative to tackle this pressing issue. Enzymes such as PETase and MHETase, which facilitate the degradation of polyethylene terephthalate (PET), in conjunction with laccases and lipases that target more recalcitrant plastics, have manifested considerable potential in deconstructing plastics at the molecular level. Notwithstanding these advancements, challenges persist regarding degradation efficiency, especially for non-PET plastics, as well as the economic viability of scaling these biotechnological processes. Furthermore, environmental parameters including temperature, pH, and oxygen levels significantly influence enzyme functionality, while regulatory and societal obstacles impede the utilization of genetically modified organisms (GMOs). Nevertheless, emerging technologies such as protein engineering, CRISPR-based gene editing, and industrial applications like bioreactors present avenues for surmounting these challenges. This article investigates the current landscape, challenges, and prospects associated with biotechnological plastic degradation, emphasizing its potential contribution to achieving global circular economy objectives and enhancing sustainable waste management strategies.
