Nanotechnology based drug delivery systems for cancer therapy have been the topic of interest for many researchers and scientists. In this research, we have studied the pH sensitive co-adsorption and release of doxorubicin (DOX) and paclitaxel (PAX) by carbon nanotube (CNT), fullerene, and graphene oxide (GO) in combination with -isopropylacrylamide (PIN). This simulation study has been performed by use of molecular dynamics. Interaction energies, hydrogen bond, and gyration radius were investigated. Results reveal that, compared with fullerene and GO, CNT is a better carrier for the co-adsorption and co-release of DOX and PAX. It can adsorb the drugs in plasma pH and release it in vicinity of cancerous tissues which have acidic pH. Investigating the number of hydrogen bonds revealed that PIN created many hydrogen bonds with water resulting in high hydrophilicity of PIN, hence making it more stable in the bloodstream while preventing from its accumulation. It is also concluded from this study that CNT and PIN would make a suitable combination for the delivery of DOX and PAX, because PIN makes abundant hydrogen bonds and CNT makes stable interactions with these drugs.

Developing vapor-solid reaction methods to prepare organic-inorganic hybrid perovskite thin films is highly compatible with processes in crystalline silicon solar cells and the thin-film photovoltaic industries, facilitating rapid industrialization. In the vapor-solid reaction, the crystallization quality of perovskite thin films is widely influenced by the crystallinity and microstructure of lead iodide (PbI) precursor films. During the thermal evaporation process of preparing the PbI precursor films, we observed that PbI tends to develop a disordered surface morphology and exhibits high crystallinity, which significantly hinders the uniform diffusion of the organic amine salt vapor during the subsequent vapor-solid reaction.

Zinc-ion batteries become a major research focus in energy storage, valued for their low cost and high safety. However, their widespread application is hindered by poor zinc anode stability caused by dendrites, side reactions, and poor performance across a wide temperature range at a strong hydrogen bond network aqueous electrolyte. In this study, we propose a strategy for the synergistic combination of a polyacrylamide hydrogel with sucrose.

Background: Few studies revealed that stromal genes regulate the tumor microenvironment (TME). However, identification of key-risk genes in the invasive ductal breast carcinoma-associated stroma (IDBCS) and their associations with the prediction of risk group remains lacking.
Methods: This study used the GSE9014, GSE10797, GSE8977, GSE33692, and TGGA BRCA datasets.

Oxidative stress significantly contributes to the progression of diabetes. The use of antioxidants or α-glycosidase inhibitors would be an effective therapeutic strategy for diabetes. To discover natural antioxidants or α-glycosidase inhibitors, two new compounds, penidione A (1) and peniorcinol D (2), were obtained from the endophytic fungus Penicillium brefeldianum F4a isolated from the roots of Houttuynia cordata Thunb.
