An interseting Cu(II)-based organic framework containing a Cu2O5 cluster, [Cu (TBA)(CH3OH)]n (1) has been hydrothermally synthesized with tetrabromoterephthalate (H2TBA) ligand, and characterized through infrared spectroscopy (IR), elemental and thermal analysis (EA), power X-ray diffraction (PXRD), and single-crystal X-ray diffraction (SCXRD) analyses. The X-ray single-crystal diffraction analysis shows that the CuII center is hexa-coordinated and situated on perfect octahedral geometry formed by four carboxyl oxygen atoms of four symmetry-related TBA2− anions and two O-donors of two reverse µ2-CH3OH bridges. Each TBA2− ligand plays as a µ4 tetra-monodentate linker and connect four Cu2+ cations together to form the three dimensional structure of 1. Surprisingly, there are no significant hydrogen bonds and π-stack interactions in 1, but the Br···Br halogen bonds interactions. Detailed topology analysis found that the 3D cluster-based metal-organic framework of 1 can be simplified to 4 topological types: a 4-c 1-nodal net dia with point symbol {66}, a 6,6-c 2-nodal net htp with point symbol {413·62}{48·66·8}, a 4,6-c 2-nodal net bpq with point symbol {32·62·72}{34·42·64·75}, and a 6,8-c 2-nodal net 6,8T902 with point symbol {34·44·54·63}{38·414·54·62}, respectively. Moreover, 1 exhibits intense solid-state luminescence emissions centered at 478 nm at room temperature, which mainly originates from the intraligand π→ π* transitions of TBA2−. The CCDC number of 1 is 2,355,788. [ABSTRACT FROM AUTHOR]

New-onset extrapulmonary tuberculosis in negative latent tuberculosis infection screening patients with Crohn's disease under anti-TNF therapy in a tuberculosis-endemic region: A case series Further, we noticed that the administration of a double-dose IFX could possibly exacerbate the severity of TB infection, as evidenced by the number of TB detection spots, coexisting PTB, and anti-TB effectiveness in Case 5, in comparison to Cases 1-3. Targeted versus universal tuberculosis chemoprophylaxis in 1968 patients with inflammatory bowel disease receiving anti-TNF therapy in a tuberculosis endemic region. Stringent screening strategy significantly reduces reactivation rates of tuberculosis in patients with inflammatory bowel disease on anti-TNF therapy in tuberculosis endemic region.

During insect larval–pupal metamorphosis, proteins in the hemolymph are absorbed by the fat body for the maintenance of intracellular homeostasis; however, the type of proteins and how these proteins are internalized into the fat body are unclear. In Bombyx mori, the developmental profiles of total proteins in the hemolymph and fat body showed that hemolymph‐decreased protein bands (55–100 kDa) were in accordance with those protein bands that increased in the fat body. Inhibition of clathrin‐dependent endocytosis predominantly blocked the transportation of 55–100 kDa proteins from the hemolymph into the fat body, which was further verified by RNA interference treatment of Bmclathrin. Six hexamerins were shown to comprise ∼90% of the total identified proteins in both the hemolymph and fat body by mass spectrum (MS) analysis. In addition, hemolymph‐specific proteins were mainly involved in material transportation, while fat body‐specific proteins particularly participated in metabolism. In this paper, four hexamerins were found for the first time, and potential proteins absorbed by the fat body from the hemolymph through clathrin‐dependent endocytosis were identified. This study sheds light on the protein absorption mechanism during insect metamorphosis. [ABSTRACT FROM AUTHOR]
