Motivation: Microbiome compositional data are often collected from several body sites and exhibit dependency among them. Analyzing microbial compositions from different sites jointly allows for effective borrowing of information by exploiting the underlying cross-site correlation, which can lead to more effective statistical analysis, especially when the sample size at one or both sites is limited. To this end, we introduce a joint model for microbiome compositions at two (or more) sites within the same subjects.

The aim of this study is to formulate a stable water-in-oil-in-water (W/O/W) double emulsion using different types of oils and electrolytes. W/O was formulated with different electrolyte solutions (W) dispersed in various oils (O) using polyglycerol polyricinoleate as a stabilizer. External aqueous phase was Tween-80 (W), and W/O dispersed in W was used.

Probiotic extracts have various positive attributes, such as antioxidant, tyrosinase inhibitory, and antimicrobial activity. produces bacteriocin, which activates the lipid membrane structure and has potential as a natural preservative for cosmetic emulsions. In this study, extract was encapsulated in liposomes and formulated as an oil-in-water (O/W) emulsion.

One-dimensional (1-D) Ag arrays were formed by electrohydrodynamic jet-printing (EHD) of polyvinylpyrrolidone (PVP, 1,300 k, Aldrich) solution ink. The 1-D Ag arrays were formed on slide glass by controlling the viscosity and printing conditions such as the tip to the substrate distance, the applied voltage, the flow rate of ink and the velocity. The printed pillars were dried at 80 °C to get rid of the solvent and sintered at 400 °C for 30 min.
