UNLABELLED Transforming growth factor-β (TGF-β) promotes cancer invasion and metastasis and is therefore a potential drug target for cancer treatment. Fresolimumab, which neutralizes all mammalian active isoforms of TGF-β, was radiolabeled with (89)Zr for PET to analyze TGF-β expression, antibody tumor uptake, and organ distribution. METHODS (89)Zr was conjugated to fresolimumab using the che...

Metallo-β-lactamases, enzymes which inactivate β-lactam antibiotics, are of increasing biological and clinical significance as a source of antibiotic resistance in pathogenic bacteria. In the present study we describe the high-resolution solution NMR structures of the Bacillus cereus metallo-β-lactamase BcII and of its complex with R-thiomandelic acid, a broad-spectrum inhibitor of metallo-β-la...

Cefepime is a fourth-generation cephalosporin which is approved in Europe and in the USA. Food and Drug Administration (FDA) approves cefepime in the treatment of febrile neutropenia. Cefepime is active against gram-negative microorganisms such as Escherichia coli, Haemophilus influenzae, Enterobacter, Klebsiella, Morganella, Neisseria, Serratia, and Proteus species. Cefepime is also active aga...

In order to continue our previous studies on some Viola species from Romania, we have analysed for the first time some active principles from aerial parts of V. declinata Waldst. et Kit. We have performed gravimetric methods for saponins and mucilages, and spectrophotometric determinations and HPLC analysis of carotenoids. We established the content in saponins (4.40%), mucilages (10.26%), and ...

Nerve growth factor (NGF) is a neurotrophic factor that is functional in the survival, maintenance and differentiation of nervous system cells. This protein has three subunits, of which the beta subunit has the main activity. Its structure consists of a cysteine knot motif made up of beta strands linked by disulfide bonds. It can be used as a therapeutic agent in the treatment of many diseases....

Hepatocellular carcinoma (HCC) represents a serious public health challenge with few therapeutic options available to cancer patients.Wnt/β-catenin pathway is thought to play a significant role in HCC pathogenesis. In this study, we confirmed high frequency of CTNNB1 (β-catenin) mutations in two independent cohorts of HCC patients and demonstrated significant upregulation of β-catenin protein i...
