The Design Of A Pcr-Based Assay To Detect And Isolate The Serine Palmitolytransferase Gene From Environmental Bacteria, Lana Taylor

Honors Theses

Sphingolipids are a natural class of lipids that function as structural elements of cell membranes and signaling molecules for important cellular activities such as cell growth, differentiation, apoptosis, recognition, and adhesion. These lipids can be found universally in eukaryotic cells as well as some species of bacteria, such as those found in the human gut microbiome and in the environment in soils. Though sphingolipid production is rare in bacteria, both eukaryotic and prokaryotic sphingolipid biosynthesis begin with the condensation of serine and palmitoyl CoA into 3-ketodihydrosphingosine catalyzed by the enzyme serine palmitoyltransferase (SPT). In recent years, several studies have shown …

Association Of Environmental Pollutants Exposure With Pulmonary Fibrosis: A Mini Review Of Molecular Mechanism Mediated, Soni Siswanto, Bantari W.K. Wardhani

Pharmaceutical Sciences and Research

Pulmonary fibrosis is a specific form of chronic progressive interstitial lung disease. Deposition of extracellular matrix, mainly collagen, is the pathogenic characteristic of pulmonary fibrosis. Many reports show that environmental pollutants, particularly asbestos, silica, mercury, cadmium, and benzo(a)pyrene, are contributed in the etiology of lung injury and a risk factor in the development of idiopathic pulmonary fibrosis (IPF) in humans. Based on its physicochemical properties, environmental pollutant-induced pulmonary fibrosis can be developed after a particular type or dose of exposure. To date, some studies have focused on variant pollutants that are induced. However, the molecular mechanism of various pollutants to …

Ameliorative Effects Of Minor Cannabinoids Over Hiv-1 Tat-Mediated Visceral Pain, Charlie Worth

Honors Theses

As the total number of people living with HIV continues to rise across the world, an effective HIV treatment is still sought after. While modern-day advanced therapies exist for mitigating much of the negative effects of HIV, the virus remains evasive and problematic in the central nervous system. Thus, even with treatment, many people living with HIV continue to suffer from a plethora of symptoms. However, a large proportion of HIV-positive patients claim to feel a reduction in those persevering symptoms after cannabis usage. This anecdotal evidence has sparked interest in the efficacy of cannabis constituents for HIV therapy. This …
