The Atheroprotective Impact Of Anti-Mir-33a-5p/3p In Cultured Pro-Inflammatory Endothelial Cells, Kun Huang

All Dissertations

Atherosclerosis is the process of cholesterol buildup within arterial cells, which is considered a leading factor that causes certain cardiovascular diseases. Cholesterol accumulation within pro-inflammatory endothelial cells is thought to induce atherogenesis and accelerate atherosclerosis progression. Evidence suggests inhibiting the microRNA miR-33a in arterial cells may promote atheroprotection via increasing ABCA1 protein expression. MiR-33a is processed into two functional strands, miR-33a-5p and miR-33a-3p. The potential atheroprotective effect of inhibiting miR-33a-5p and/or miR-33a-3p precisely in pro-inflammatory endothelial cells is not fully understood, as data is scant regarding what potential atheroprotective impact ABCA1-dependent cholesterol within pro-inflammatory endothelial cells demonstrates, which occurs via …

Bioactivity And Synergism Of Tagpo (Ardisia Tomentosa) Molluscicidal Extracts, Darwin C. Gomez, Grechelle Socias, Rosemarie Galanza, Florlyn C. Gayas Ma., Fe T. Piedad, Brian John Sarno

The Philippine Agricultural Scientist

Population control of golden apple snails (GAS, Pomacea canaliculata) is beneficial in rice farming; however, the associated control measures can be expensive and time-consuming. Currently, farmers use synthetic molluscicides such as niclosamide to control GAS infestation, but this has some drawbacks. For example, niclosamide has broad toxicity to non-target organisms and negatively affects the growth of rice seedlings. Plant extracts with potent bioactivity and low toxicity to non-target organisms are attractive alternatives to synthetic molluscicides. In this study, the bioactivity of the crude fruit extract of tagpo (Ardisia tomentosa) was assessed against GAS and tilapia (Oreochromis niloticus) fries. The potential …
