The physico-chemical properties of spray-dried pitaya peel powders kept at accelerated (45 ± 2°C) and room temperature (28 ± 2°C) for 14 weeks and 6 months, respectively were evaluated. Changes in physico-chemical properties of the peel powder were used as indicators of stability, while changes of the betacyanin pigment retention was used to calculate the shelf-life of the powder. Storage tempe...

The D-optimal mixture experimental design was employed to optimize the melting point of natural lipstick based on pitaya (Hylocereus polyrhizus) seed oil. The influence of the main lipstick components-pitaya seed oil (10%-25% w/w), virgin coconut oil (25%-45% w/w), beeswax (5%-25% w/w), candelilla wax (1%-5% w/w) and carnauba wax (1%-5% w/w)-were investigated with respect to the melting point p...

Cysteine proteases and tyrosine kinases are two classes of enzymes that have been implicated in the coagulation cascade. This cascade is responsible for the aggregation of human platelets and their role in thrombosis. Understanding the interactions between these two systems is essential in developing treatments to reduce the risk of acute myocardial infarction and ischemic stroke. A modified mo...

The average seismic velocity and density jumps across the 410- and 660-kilometer discontinuities in the upper mantle were determined by modeling the observed range dependence in long-period seismic wave arrivals that reflect off of these interfaces. The preliminary reference Earth model (PREM) is within the computed 95 percent confidence ellipse for the 410-km discontinuity but outside the allo...

Using recently collected high-resolution seismic data along a dense linear transect across Ohio, West Virginia, and Virginia (called Mid-Atlantic Geophysical Integrative Collaboration (MAGIC) profile), we analyze P-to-S receiver functions to investigate the undulations of mantle transition zone (MTZ) discontinuities (410- 660-km) beneath central Appalachian region. Our results incorporating eff...

Neuronal activity orchestrates the proper development of the neuronal circuitry by regulating both transcriptional and post-transcriptional gene expression programmes. How these programmes are coordinated, however, is largely unknown. We found that the transcription of miR379-410, a large cluster of brain-specific microRNAs (miRNAs), is induced by increasing neuronal activity in primary rat neu...
