Immunostaining in lungs of patients who died with CovID-19 infection showed increased intensity and distribution of chondroitin sulfate and decline in N-acetylgalactostamine-4-sulfatase(Arylsulfatase B;ARSB).To explain these findings,human small airway epithelial cells were exposed to the SARS-CoV-2 spike protein receptor binding domain(SPRBD)and transcriptional mechanisms were ***-p38 MAPK and phospho-SMAD3 increased following exposure to the SPRBD,and their inhibition suppressed the promoter activation of the carbohydrate sulfotransferases CHST15 and CHST11,which contributed to chondroitin sulfate *** in ARSB was mediated by phospho-38 MAPK-induced N-terminal Rb phosphorylation and an associated increase in Rb-E2F1 binding and decline in E2F1 binding to the ARSB *** increases in chondroitin sulfotransferases were inhibited when treated with phospho-p38-MAPK inhibitors,SMAD3(SIS3)inhibitors,as well as antihistamine desloratadine and antibiotic *** the mouse model of carrageenan-induced systemic inflammation,increases in phosphop38 MAPK and expression of CHST15 and CHST11 and declines in DNA-E2F binding and ARSB expression occurred in the lung,similar to theobserved effects in this SPRBD model of COVID-19 *** accumulation of chondroitin sulfates is associated with fibrotic lung conditions and diffuse alveolar damage,increased attention to p38-MAPK inhibition may be beneficial in amelioratingCovid-19infections.

通过聚焦于世界一流的奢侈品供给地——伦敦,本文探讨了奢侈品行业对于城市创造力以及经济能力的贡献。伦敦奢侈品行业的发达,被认为是伦敦城市政治、经济、社会、文化等特征多方面沉淀及财富创造的一个结果。然而,也有人主张奢侈品行业不仅仅是得益于伦敦经济的成功,也为伦敦在创意经济时代保持世界一流城市的地位作出了贡献。因此,正如Sombart(1967)将资本主义经济体系的发展归因于18世纪的奢侈品需求,在21世纪如伦敦等全球城市经济繁荣的环境下,奢侈品行业一直在资本主义维稳方面起到举足轻重的作用。

Cancer cells reprogram their gene expression to promote growth,survival,proliferation,and *** unique expression of certain uptake transporters in cancers and their innate function to concentrate small molecular substrates in cells make them ideal targets for selective delivering imaging and therapeutic agents into cancer *** this review,we focus on several solute carrier(SLC)transporters known to be involved in transporting clinically used radiopharmaceutical agents into cancer cells,including the sodium/iodine symporter(NIS),norepinephrine transporter(NET),glucose transporter 1(GLUT1),and monocarboxylate transporters(MCTs).The molecular and functional characteristics of these transporters are reviewed with special emphasis on their specific expressions in cancers and interaction with imaging or theranostic agents[e.g.,Ⅰ-123,Ⅰ-131,123Ⅰ-iobenguane(mIBG),18F-fluorodeoxyglucose(18F-FDG)and 13C pyruvate].Current clinical applications and research areas of these transporters in cancer diagnosis and treatment are ***,we offer our views on emerging opportunities and challenges in targeting transporters for cancer imaging and *** analyzing the few clinically successful examples,we hope much interest can be garnered in cancer research towards uptake transporters and their potential applications in cancer diagnosis and treatment.

The discovery of Severe Acute Respiratory Syndrome-Coronavirus-2 (SARS-CoV-2) in Wuhan, Hubei province, China, in December 2019 raised global health warnings. Quickly, in 2020, the virus crossed borders and infected individuals across the world, evolving into the COVID-19 pandemic. Notably, early signs of the virus’s existence were observed in various countries before the initial outbreak in Wuhan. As of 12th of April, the respiratory disease had infected over 762 million people worldwide, with over 6.8 million deaths recorded. This has led scientists to focus their efforts on understanding the virus to develop effective means to diagnose, treat, prevent, and control this pandemic. One of the areas of focus is the isolation of this virus, which plays a crucial role in understanding the viral dynamics in the laboratory. In this study, we report the isolation and detection of locally circulating SARS-CoV-2 in Kenya. The isolates were cultured on Vero Cercopithecus cell line (CCL-81) cells, RNA extraction was conducted from the supernatants, and reverse transcriptase-polymerase chain reaction (RT-PCR). Genome sequencing was done to profile the strains phylogenetically and identify novel and previously reported mutations. Vero CCL-81 cells were able to support the growth of SARS-CoV-2 in vitro, and mutations were detected from the two isolates sequenced (001 and 002). Genome sequencing revealed the circulation of two isolates that share a close relationship with the Benin isolate with the D614G common mutation identified along the S protein. These virus isolates will be expanded and made available to the Kenya Ministry of Health and other research institutions to advance SARS-CoV-2 research in Kenya and the region.
