Characterization of Artemether-lumefantrine liposomes for parenteral administration

Artemisins remain the drug of choice in the treatment of uncomplicated malaria. Liposomes encapsulating artemether and lumefantrine were formulated through the thin-layer evaporation method. The liposomes were evaluated for particle size, polydispersity index, encapsulation efficiency, stability studies using Triton-X. Results show mean particle sizes for the empty liposomes at 120.7 nm +4.52 with polydispersity index (PI)...

In this paper, we derived the posterior density function of parameters of linear regression model when the various structures of heteroscedasticity consistent covariance estimators developed by White (1980) Mackinnon and White (1985) and and Cribari-Neto (2004) were incorporated. We specify non-informative uniform prior for the parameters of the model . From the joint posterior density function, we derived the marginal...

Linear and nonlinear properties of heartbeat time series in obesity

In previous studies, the property of ‘complexity’ was suggested as a systemic profile of a human cardiovascular system. A loss of complexity in heartbeat time series is a significant bio-marker for assessing the aging and dysfunctions of a cardiac system. In different approaches by phase-rectified signal average (PRSA), a low deceleration capacity (DC) in heart rate variability (HRV) demonstrated a high risk of cardiac...
