Grazing-incidence X-ray diffraction elucidates structural correlations in fluid monolayers of lipids and surfactants.

Biological membranes predominantly consist of fluid lipid phases featuring lateral mobility and a considerable disorder of their hydrocarbon chains. Langmuir monolayers of lipids at the air/water interface are versatile model systems for fundamental physicochemical and biophysical membrane investigations. Grazing-incidence X-ray diffraction (GIXD) is a powerful tool for the structural characterization of such monolayers but has so far been used almost exclusively for lipid phases of crystalline ordering giving rise to sharp diffraction peaks.

An acoustic metamaterial with space-time modulated densitya).

Space-time modulation opens the door for unprecedented wave behavior control, such as nonreciprocal wave manipulation. Here is proposed a one-dimensional space-time modulated membrane system aiming to realize a kind of acoustic metamaterial with space-time modulated effective density. Three different approaches, namely, the effective medium method, transfer matrix method, and time-domain simulation, are applied to analyze the acoustic response of the system under a monochromatic incidence.

An injury-induced mesenchymal-epithelial cell niche coordinates regenerative responses in the lung.

Severe lung injury causes airway basal stem cells to migrate and outcompete alveolar stem cells, resulting in dysplastic repair. We found that this "stem cell collision" generates an injury-induced tissue niche containing keratin 5 epithelial cells and plastic Pdgfra mesenchymal cells. Single-cell analysis revealed that the injury-induced niche is governed by mesenchymal proliferation and Notch signaling, which suppressed Wnt/Fgf signaling in the injured niche.

A biomimetic solution, albumin-doxorubicin molecular complex, targeting tumor and tumor-draining lymph nodes.

Chemotherapy-induced immunologic cell death is haunted by the non-specific distribution of chemotherapeutic drugs and insignificant immune activation effects, which render efforts to inhibit the distant metastasis of tumors frustrated. Given the pivotal role that lymph nodes play in tumor metastasis, it is of vital importance whether the drug delivery to tumor-draining lymph nodes (TDLNs) succeeds. In the current study, we developed a doxorubicin-albumin complex (DOX-HSA) solution with the specific ability to simultaneously target the primary tumor and the TDLNs.

Development of an Intravenously Stable Disulfide-Rich Peptide for the Treatment of Chemotherapy-Induced Neuropathic Pain.

α-conotoxins (α-Ctxs), a class of disulfide-rich conopetides, are excellent drug leads due to their small size, high selectivity, and potency for specific membrane receptors and ion channels involved in pain transmission. However, their high susceptibility to proteolytic degradation limits their therapeutic potential. In this study, we designed and synthesized a series of conformationally stable analogues of α-Ctx Mr1.

Enhanced vertical railway track quality index with dynamic responses from moving trains.

The conventional vertical track quality index (TQI) based on the standard deviation of longitudinal levels yields standardized railway track condition assessment. Nevertheless, its capability to identify problems is limited, particularly in the ballast and substructure layers when abrupt changes affect train-track interaction. Previous research shows that dynamic responses from moving trains via axle box acceleration (ABA) measurements can quantify abrupt changes in the vertical dynamic responses.
