Advances in immunotherapy are revolutionizing the treatments of certain cancers, especially those in the blood. However, wider applications for eradicating solid tumors have been slow to emerge. A likely reason is the presence of myeloid-derived suppressor cells (MDSCs) in the tumor microenvironment that secrete immunosuppressive molecules which attenuate the attack of immune cells. We hypothesize that small molecule Wnt/Beta- Catenin inhibitors can be used to modulate the immunosuppressive actions of MDSCs and increase the effectiveness of immunotherapy treatments, such as with chimeric antigen receptor (CAR) T-cells. The Wnt/Beta-Catenin Pathway has been shown to be a crucial driving force behind the …

Phytochemicals, such as monoterpenes, polyphenols, curcuminoids, and flavonoids, are known to have anti-inflammatory, antioxidant, neuroprotective, and procognitive effects. In this study, the effects of several polyhydroxy flavonoids, as derivatives of differently substituted 5,7-dihydroxy-4H-chromen-4-one including apigenin, genistein, luteolin, kaempferol, quercetin, gossypetin, and phloretin with different lipophilicities (cLogP), as well as topological polar surface area (TPSA), were tested for induction of Ca2+ transients by α7 human nicotinic acetylcholine (α7 nACh) receptors expressed in SH-EP1 cells. Apigenin (10 μM) caused a significant potentiation of ACh (30 μM)-induced Ca2+ transients, but did not affect Ca2+ transients induced by high K+ …

Vancomycin is the drug of choice for methicillin-resistant Staphylococcus aureus keratitis and other ocular infections. Vancomycin ophthalmic drops are not commercially available and require compounding. The present study was designed to investigate the stability of vancomycin ophthalmic drops in normal saline, phosphate-buffered saline (PBS), and balanced salt solution (BSS) while stored at room temperature or under refrigeration. Vancomycin ophthalmic drops (50 mg/mL) were aseptically prepared from commercially available intravenous powder using PBS, BSS, and saline. Solutions were stored at room temperature and in a refrigerator for 28 days. The vancomycin stability was tested by a microbiology assay and high-performance liquid …
