The refractive index (RI) of human milk serum (also known as whey, milk soluble fraction or milk plasma) depends on the individual molecular species dissolved in the serum and their concentrations. Although the human milk serum RI is known to influence milk analysis methods based on light scattering, the RI dependency on human milk serum composition is currently unknown. Therefore, we systematically evaluate how the RI depends on natural variations in macronutrient concentrations in the soluble fraction.

- Interest in how plant-based diets affect the gut microbiome is increasing, but there's limited research on how different diet patterns (omnivore, vegetarian, vegan) impact microbiome profiles across various populations.
- A study involving over 21,000 individuals found that gut microbiome profiles can effectively differentiate between these diet patterns, with a mean accuracy of 85%.
- Key findings show that omnivore microbiomes are heavily influenced by red meat consumption, which is linked to negative health markers, while vegan microbiomes are associated with healthier outcomes and overlap with specific food and soil microbes.
The sphingolipid network is sustained principally by the balance of bioactive sphingolipid molecules and their regulation by sphingolipid-metabolizing enzymes. The components in the lipid system display key functions in numerous cellular and disease conditions including virus infections. During the COVID-19 pandemic, there was a fruitful effort to use an inhibitor that blocks the activity of sphingosine kinase (SphK) 2 to cure the devastating disease.

We developed and tested a prototype portable UV-C device to sterilize high flows of viral-contaminated air from a simulated patient source at airflow rates of up to 100 l/m. Our device consisted of a central quartz tube surrounded 6 high-output UV-C lamps, within a larger cylinder allowing recirculation past the UV-C lamps a second time before exiting the device.

Methods: This is a retrospective cohort study utilizing propensity score matched groups. Patients undergoing elective LD at an ASC with two-year follow-up were identified and grouped based on insurance type (WC or CI).
