Preparation, stability, and in vitro transport of soybean protein-based diosgenin nanoemulsions

Soybean protein isolate (SPI)-stabilized nanoemulsions (NEs) were formulated to encapsulate diosgenin (DIO) to enhance its water solubility and bioavailability. The influence of DIO concentrations on NEs' properties was investigated, and their environmental stability and cell permeability were also assessed. Results demonstrated that DIO significantly affected all the physicochemical properties of NEs. NEs with 1.0 mg/mL of DIO exhibited smaller droplet size (209 nm), lower polydispersity index (0.17), and higher stability coefficient (95.8 %). Furthermore, DIO-SPI NEs displayed better stability under appropriate pH (<4 or > 5), NaCl concentrations (≤0.3 M), temperatures (≤60 °C), and freeze-thaw cycles (≤2), as well as storage at 4 °C. Moreover, encapsulating DIO in NEs reduced its toxicity towards cells and enhanced its transport efficiency, which reached 3.16 ∼ 4.87 × 10-6. These findings highlight the potential of SPI-based NEs as a promising carrier for the efficient delivery of DIO.

The cultural differences in the effects of carbon emissions - an EKC analysis

The postmodernism stance critiques the current discourse of modern consumption-based societies. These societies legitimize their embedded beliefs and actions based on their lifestyle reflected through their consumption patterns. Their consumption patterns relate to carbon footprints that are yet to be explored in the current body of knowledge at the macro level. The legitimacy of their lifestyle and consumption patterns rely on their conscious efforts in reducing carbon footprints. This study uses the environmental Kuznets curve model and explores the impact of household lifestyle and household consumption patterns on CO₂ emissions across different cultures and societies worldwide. 49 countries were taken to assess how different cultures define consumption patterns related to CO₂ emission. The results showed that the curvilinear relationship between consumption and CO₂ depends on the country's national cultural orientation.

Decoding the global outbreak of COVID-19: the nature is behind the scene

The sudden emergence of SARS-CoV-2 causing the global pandemic is a major public health concern. Though the virus is considered as a novel entity, it is not a completely new member. It is just a new version of previously emerged human SARS corona virus. The rapid evolving nature by changing host body environment and extreme environmental stability, collectively makes SARS-CoV-2 into an extremely virulent genetic variant. The evolution of the virus has been occurred by the continuous process of molecular genetic manipulation, through mutation, deletion and genetic recombinationevents. Different host body environment acts as the supportive system for the pathogen which creates extreme selective pressure. By the process of genetic evolution the pathogen developes new characters. Then the new version of the virus has been naturally selected by susceptible human host and adapt itself inside the host body causing deadly effect. Moreover, extreme environmental stability helps in the process of viral survival outside the host and its transmission. Thus both the host body or internal environment and the external environment performs equally as a source, responsible for shaping the genetic evolution of the SARS-CoV-2 towards theCOVID-19 disease fitness in nature in a pandemic form.
