DataSheet1_Neuropsychiatric disorders in chronic hepatitis C patients after receiving interferon or direct-acting antivirals: a nationwide cohort study.docx
Background: Data on the neuropsychological outcomes after receiving direct-acting antivirals (DAAs) among chronic hepatitis C (CHC) patients have not been well-documented.Aim: This study aimed to evaluate the difference in incidence of neuropsychological disorders (NPDs) after treatment completion between CHC patients receiving interferon (IFN) therapy and DAA therapy.Methods: A nationwide retrospective cohort study was performed using Taiwan’s National Health Insurance Research Database (NHIRD) between 2010 and 2018. CHC patients without pre-existing mental disorders were included and divided into the treatment (Tx)-naïve DAA group, retreatment (re-Tx) DAA group, and Tx-naïve IFN group based on their HCV therapy. Propensity score matching was used to balance baseline differences between groups. The primary outcome was the incidence of NPDs during 6 months after completion of therapy.Results: After one-to-one matching, there were 6,461 pairs of patients selected from the Tx-naïve DAA group and Tx-naïve IFN group and 3,792 pairs from the re-Tx DAA group and Tx-naïve IFN group. A lower incidence of NPDs was observed in the Tx-naïve DAA group than in the Tx-naïve IFN group (HR = 0.72, 95% CI = 0.55–0.94, and p = 0.017). The risk of NPDs did not differ between the re-Tx DAA group and the Tx-naïve IFN group (HR = 0.74, 95% CI: 0.52–1.05, and p = 0.092).Conclusion: DAA therapy was associated with lower risk of NPDs when compared with IFN therapy among Tx-naïve CHC patients in a 6-month period after treatment completion, especially among the patients less than 65 years, male gender, and cirrhosis.</p
Fluorescent Ensemble Based on Bispyrene Fluorophore and Surfactant Assemblies: Sensing and Discriminating Proteins in Aqueous Solution
A particular
bispyrene fluorophore (<b>1</b>) with two pyrene moieties covalently
linked via a hydrophilic spacer was synthesized. Fluorescence measurements
reveal that the fluorescence emission of <b>1</b> could be well
modulated by a cationic surfactant, dodecyltrimethylammonium bromide
(DTAB). Protein sensing studies illustrate that the selected ensemble
based on <b>1</b>/DTAB assemblies exhibits ratiometric responses
to nonmetalloproteins and turn-off responses to metalloproteins, which
can be used to differentiate the two types of proteins. Moreover,
negatively charged nonmetalloproteins can be discriminated from the
positively charged ones according to the difference in ratiometric
responses. Fluorescence sensing studies with control bispyrenes indicate
that the polarity of the spacer connecting two pyrene moieties plays
an important role in locating bispyrene fluorophore in DTAB assemblies,
which further influences its sensing behaviors to noncovalent interacting
proteins. This study sheds light on the influence of the probe structure
on the sensing performance of a fluorescent ensemble based on probe
and surfactant assemblies
Table1_Revealing phosphorylation regulatory networks during embryogenesis of honey bee worker and drone (Apis mellifera).XLSX
Protein phosphorylation is known to regulate a comprehensive scenario of critical cellular processes. However, phosphorylation-mediated regulatory networks in honey bee embryogenesis are mainly unknown. We identified 6342 phosphosites from 2438 phosphoproteins and predicted 168 kinases in the honey bee embryo. Generally, the worker and drone develop similar phosphoproteome architectures and major phosphorylation events during embryogenesis. In 24 h embryos, protein kinases A play vital roles in regulating cell proliferation and blastoderm formation. At 48–72 h, kinase subfamily dual-specificity tyrosine-regulated kinase, cyclin-dependent kinase (CDK), and induced pathways related to protein synthesis and morphogenesis suggest the centrality to enhance the germ layer development, organogenesis, and dorsal closure. Notably, workers and drones formulated distinct phosphoproteome signatures. For 24 h embryos, the highly phosphorylated serine/threonine-protein kinase minibrain, microtubule-associated serine/threonine-protein kinase 2 (MAST2), and phosphorylation of mitogen-activated protein kinase 3 (MAPK3) at Thr564 in workers, are likely to regulate the late onset of cell proliferation; in contrast, drone embryos enhanced the expression of CDK12, MAPK3, and MAST2 to promote the massive synthesis of proteins and cytoskeleton. In 48 h, the induced serine/threonine-protein kinase and CDK12 in worker embryos signify their roles in the construction of embryonic tissues and organs; however, the highly activated kinases CDK1, raf homolog serine/threonine-protein kinase, and MAST2 in drone embryos may drive the large-scale establishment of tissues and organs. In 72 h, the activated pathways and kinases associated with cell growth and tissue differentiation in worker embryos may promote the configuration of rudimentary organs. However, kinases implicated in cytoskeleton organization in drone embryos may drive the blastokinesis and dorsal closure. Our hitherto most comprehensive phosphoproteome offers a valuable resource for signaling research on phosphorylation dynamics in honey bee embryos.</p
Noncovalent Tailoring of the Binding Pocket of Self-Assembled Cages by Remote Bulky Ancillary Groups
The binding properties of a self-assembled coordination
cage were
subtly tuned by ancillary groups on the metal corners of the cage.
Since the bulky mesityl groups of the ligand hang over the cage cavity,
the effective cavity volume is reduced. Due to the tighter guest packing
inside the shrunken cavity, smaller guests were efficiently bound
and guest motion was restricted even at high temperatures
