The detailed molecular mechanism of transferrin-tagged thymoquinone nanoparticle mediated apoptotic induction in non-small cell lung carcinoma showing the involvement of p53 dependent synergistic activation of miR-34a and miR-16 in the pathway.
Epidermal growth factor receptor (EGFR) normally over-express in non-small cell lung cancer (NSCLC) and its mutations act as oncogenic drivers in the cellular signal transduction pathway and induce downstream activation...
Till date most of the accessible therapeutic options are virtually non-responsive towards Triple-negative breast cancer (TNBC) due to their highly aggressive and metastatic nature. Interestingly, chemotherapy reacts soundly in many...
A novel reactor was designed and implemented for water purification using deep ultraviolet light emitting diodes (LEDs). The focus was on minimizing the number of LEDs required for effective germicidal action. Simulation studies were carried out on the flow of water as well as the irradiance of UV. Variation was made in the beam divergence of the UV sources and reflectivity of optical coatings used for photon recycling. Based on optimized reactor designs, water purification was carried out both in the static and flow-through configuration. Water from various sources was spiked with a known bacterial strain, exposure studies were carried out and germicidal effect was determined. Our results indicate that under optimal design, a 3 mL volume of water shows a three order inactivation using a single UV-LED in a static reactor in 180 s. For a flow-through geometry, only three LEDs were used in the reactor implementation, and a multi-pass procedure was used to purify 150 mL of water from an Escherichia coli CFU count of 4.3 × 104/mL to 12/mL. While slow, this process requires less than 2 W, and can be powered from rechargeable sources. Faster processes can be implanted using multiple such reactor units in parallel, and can be optimized to the requirement and power levels.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
