work (BCN) interpenetrating structure. dHAM dydrogel has advantages, e.g., good mechanical properties, slow degradation and convenient operation, so it is conducive to large-area or full-thickness skin defect healing.Loading-induced cartilage exudation causes loss of fluid from the tissue, joint space thinning and, in a long term prospective, the insurgence of osteoarthritis. Fortunately, experiments show that joints recover interstitial fluid and thicken during articulation after static loading, thus reversing the exudation process. Here, we provide the first original theoretical explanation to this crucial phenomenon, by implementing a numerical model capable of accounting for the multiscale porous lubrication occurring in joints. We prove that sliding-induced rehydration occurs because of hydrodynamic reasons and is specifically related to a wedge effect at the contact inlet. Furthermore, numerically predicted rehydration rates are consistent with experimentally measured rates and corroborate the robustness of the model here proposed. The paper provides key information, in terms of fundamental lubrication multiscale mechanisms, to understand the rehydration of cartilage and, more generally, of any biological tissue exhnt for cartilage-mimicking biomaterials.
Rev-erbα represents a powerful transcriptional repressor involved in immunity. However, the regulation, function, and clinical relevance of Rev-erbα in Helicobacter pylori (H.pylori) infection are presently unknown.

Rev-erbα was examined in gastric samples from H.pylori-infected patients and mice. Gastric epithelial cells (GECs) were isolated and infected with H.pylori for Rev-erbα regulation assays. Gastric tissues from Rev-erbα
and wild-type (littermate control) mice or these mice adoptively transferred with CD4
T cells from IFN-γ
and wild-type mice, bone marrow chimera mice and mice with invivo pharmacological activation or inhibition of Rev-erbα were examined for bacteria colonization. GECs, CD45
CD11c
Ly6G
CD11b
CD68
myeloid cells and CD4
T cells were isolated, stimulated and/or cultured for Rev-erbα function assays.

Rev-erbα was increased in gastric mucosa of H.pylori-infected patients and mice. H.pylori induced GECs to express Rev-erbα via the phosphorylated cagA that activated ERK d for local innate and adaptive defense against H. pylori.
Central venous stenosis is one of the most challenging complications in patients requiring hemodialysis. Venous thoracic outlet syndrome is an underappreciated cause of central venous stenosis in patients requiring dialysis that can result in failed percutaneous intervention and loss of a functioning dialysis access. Limited data exist about the safety and outcomes of first rib resection in patients requiring hemodialysis, and the results have been confounded by the various surgical approaches used. The purpose of the present study was to evaluate the safety, operative outcomes, and patency of the existing dialysis access after transaxillary thoracic outlet decompression.

A retrospective medical record review was performed from January 2008 to December 2019 of patients who had undergone thoracic outlet decompression for subclavian vein stenosis with ipsilateral upper extremity hemodialysis access. The baseline characteristics and comorbidities were reviewed. The operative and postoperative course were evasic compression at the costoclavicular junction. These patients might benefit from transaxillary first rib resection, scalenectomy, and venolysis.
Thoracic outlet decompression via the transaxillary approach is a technically feasible and safe operation in patients with ipsilateral upper extremity hemodialysis access. Patients with threatened dialysis access due to subclavian vein stenosis should be carefully evaluated for possible extrinsic compression at the costoclavicular junction. These patients might benefit from transaxillary first rib resection, scalenectomy, and venolysis.We report herein design and synthesis of a new series of 3,7-bis-benzylidenes of ciprofloxacin. Most of the target compounds revealed good cytotoxic activity; the most potent 4e and 4i achieved strong broad spectrum antiproliferative activity with comparable activity to Doxorubicin with IC50 (µM) of 1.21 ± 0.02, 0.87 ± 0.04, 1.21 ± 0.02; 0.41 ± 0.02, 0.57 ± 0.06, 1.31 ± 0.04 and 1.26 ± 0.01, 1.79 ± 0.04, 0.63 ± 0.01 against leukemia cancer cell line HL-60 (TB), colon cancer cell line HCT-116 and breast cancer cell line MCF7, respectively. check details Moreover, the most potent derivative 4i induced apoptosis at G2/M phase Investigating the mechanism of action of compounds 4e, 4 h and 4i exhibited promising dual TOP Iα and TOP IIB % inhibition comparable to Camptothecin and Etoposide; respectively. Docking of 4e, 4 h and 4i into the active site of topo I and II proteins compared to Camptothein and Etoposide revealed acceptable binding score and augmented enzyme assay data. Hence, 4e and 4i are promising targeted antiproliferative dual acting TOP Iα TOP IIB inhibitors that require further optimization.Sirtuins play a prominent role in several cellular processes and are implicated in various diseases. The understanding of biological roles of sirtuins is limited because of the non-availability of small molecule inhibitors, particularly the specific inhibitors directed against a particular SIRT. We performed a high-throughput screening of pharmacologically active compounds to discover novel, specific, and selective sirtuin inhibitor. Several unique in vitro sirtuin inhibitor pharmacophores were discovered. Here, we present the discovery of novel chemical scaffolds specific for SIRT3. We have demonstrated the in vitro activity of these compounds using label-free mass spectroscopy. We have further validated our results using biochemical, biophysical, and computational studies. Determination of kinetic parameters shows that the SIRT3 specific inhibitors have a moderately longer residence time, possibly implying high in vivo efficacy. The molecular docking results revealed the differential selectivity pattern of these inhibitors against sirtuins. The discovery of specific inhibitors will improve the understanding of ligand selectivity in sirtuins, and the binding mechanism as revealed by docking studies can be further exploited for discovering selective and potent ligands targeting sirtuins.
