The original diameter velocity loop method (ln(D)U-loop) cannot accurately extract the blood vessel diameter waveform when the quality of ultrasound image data is not high (such as obesity, age, and the operation of the ultrasound doctor), so it is unable to measure the pulse wave velocity (PWV) of the ascending aorta. This study proposes a diameter waveform extraction method combining threshold, gradient filtering, and the center of gravity method. At the same time, the linear regression method of searching for the rising point of the systolic period is replaced by the optimal average of two linear regression methods.

Pancreatic ductal adenocarcinoma (PDAC) is characterized by an extensive fibroinflammatory stroma and often experiences conditions of insufficient oxygen availability or hypoxia. Cancer-associated fibroblasts (CAF) are a predominant and heterogeneous population of stromal cells within the pancreatic tumor microenvironment. Here, we uncover a previously unrecognized role for hypoxia in driving an inflammatory phenotype in PDAC CAFs.

The discovery of novel high-nuclearity oxo-clusters considerably promotes the development of cluster science. We report a high-nuclearity oxo-cluster-based compound with acid/alkali-resistance and radiation stabilities, namely, (HO)[CdSbO(l-tta)(l-Htta)(HO)]·29HO (FJSM-CA; l-Htta = l-tartaric acid), which features a two-dimensionally anionic layer based on the largest Sb-oxo-clusters with 28-metal-ion-core [CdSbO]. It is challenging to efficiently capture Sr, Ba (analogue of Ra), and [UO] ions from aqueous solutions due to their high water solubility and environmental mobility, while it is unprecedented that a novel Sb-oxo-cluster-based framework material FJSM-CA can efficiently remove these hazardous ions accompanied with intriguing structural transformations.

Thin-section magnetic resonance imaging (MRI) can provide higher resolution anatomical structures and more precise clinical information than thick-section images. However, thin-section MRI is not always available due to the imaging cost issue. In multicenter retrospective studies, a large number of data are often in thick-section manner with different section thickness.

Purpose: Prospective prediction of pharmacokinetic properties for individuals of different ethnic groups could provide useful information for the design of multiregional clinical trials. The accuracy of interethnic scaling of fraction unbound (f) of a drug could determine in large part the predictive capability of volume of distribution as well as renal clearance. As such, exploring the interethnic extrapolation of f from healthy Caucasian to Chinese subjects and associated effect on the scaling of volume of distribution is highly warranted.

Unconventional ion exchangers can achieve efficient removal of [UO], Cs, and Sr ions from complex aqueous solutions and are of great interest for environmental remediation. We report two new gallium thioantimonates, [MeNH][GaSbS]·HO (FJSM-GAS-1) and [EtNH][GaSbS]·HO (FJSM-GAS-2), which present excellent ion exchange properties for [UO], Cs, and Sr ions. They exhibit high ion exchange capacities for [UO], Cs, and Sr ions ( q = 196 mg/g, q = 164 mg/g, and q = 80 mg/g for FJSM-GAS-1, q = 144 mg/g for FJSM-GAS-2) and short equilibrium times for [UO] ion exchange (5 min for FJSM-GAS-1 and 15 min for FJSM-GAS-2, respectively).

Organic anion-transporting polypeptide (OATP) 1A2 has the potential to be a target for central nervous system drug delivery due to its luminal localization at the human blood-brain barrier and broad substrate specificity. We found OATP1A2 mRNA expression in the human brain to be comparable to breast cancer resistance protein and OATP2B1 and much higher than P-glycoprotein (P-gp), and confirmed greater expression in the brain relative to other tissues. The goal of this study was to establish a model system to explore OATP1A2-mediated transcellular transport of substrate drugs and the interplay with P-gp.
