Perfluorinated tetrathiacalix[4]arene was obtained by heating perfluoro--xylene with thiourea or 2,5-difluoro-4,6-bis(trifluoromethyl)benzene-1,3-dithiol at 90 °C. Interaction of perfluoro--xylene with resorcinol or orcinol under mild conditions and subsequent heating of the mixture with 2,5-difluoro-4,6-bis(trifluoromethyl)benzene-1,3-dithiol leads to polyfluorinated dioxadithiacalix[4]arenes. Triphenyl and pentaphenyl ethers formed by the interaction of perfluoro--xylene with resorcinol under heating with thiourea gives polyfluorinated oxathiacalixarenes containing six and five aromatic nuclei, respectively.

MAL2 and rab17 selectively redistribute invadopodia proteins to laterally-induced protrusions in hepatocellular carcinoma cells.
Mol Biol Cell

Department of Biology, The Catholic University of America, Washington, DC, 20064.
MAL2 (myelin and lymphocyte protein 2) and rab17 have been identified as hepatocellular carcinoma tumor suppressors. However, little is known how their functions in hepatic polarized protein sorting/trafficking translates into how they function in the epithelial to mesenchymal transition and/or the mesenchymal to epithelial transition in metastases. To investigate this, we expressed MAL2 and rab17 alone or together in hepatoma-derived Clone 9 cells (that lack endogenous MAL2 and rab17).

Background: Childhood obesity prevalence remains high, especially in racial and ethnic minority populations with low incomes. This epidemic is attributed to various dietary behaviors, including increased consumption of energy-dense foods and sugary beverages and decreased intake of fruits and vegetables. Interactive, technology-based approaches are emerging as promising tools to support health behavior changes.

Background: Mobile health apps have shown promising results in improving self-management of several chronic diseases in patients. We have developed a mobile health app (Cardiomeds) dedicated to patients with heart failure (HF). This app includes an interactive medication list; daily self-monitoring of symptoms, weight, blood pressure, and heart rate; and educational information on HF delivered through various formats.

Department of Chemistry, Birla Institute of Technology and Science Pilani, Hyderabad 500078, India.
In this work, we have explored the metal ion sensing properties of two bisbenzimidazole-based fluorescent probes, that differ in their conformational flexibility, in an aqueous medium. The compound with a flexible methyl spacer (1) experienced blue shifts in its absorption and emission maxima (along with a turn-off response) upon the addition of Hg ions. On the contrary, the compound with a relatively rigid structure (2) showed red shifts in both its absorption and emission maxima (along with a turn-off response) when treated with Hg under similar conditions.

Importance: Perioperative bleeding is common in general surgery. The POISE-3 (Perioperative Ischemic Evaluation-3) trial demonstrated efficacy of prophylactic tranexamic acid (TXA) compared with placebo in preventing major bleeding without increasing vascular outcomes in noncardiac surgery.
Objective: To determine the safety and efficacy of prophylactic TXA, specifically in general surgery.
