Engineering Bacterial Secretion Systems for Enhanced Tumor Imaging and Surgical Guidance
Advanced Materials, EarlyView.This study presents a novel contrast agent platform, Streptavidin Associated Salmonella (SAS), for fluorescence image guided surgery. SAS selectively colonizes tumors and secretes streptavidin, enabling precise delineation of invasive tumor margins with prolonged signal retention.

Comparison of conservative treatment versus transcatheter arterial embolisation for the treatment of spontaneously ruptured hepatocellular carcinoma [PDF]
, 2018 Purpose: To elucidate the prognostic factors in the spontaneous rupture of hepatocellular carcinoma (HCC) and to determine whether transcatheter arterial embolisation (TAE) is associated with better prognosis compared to conservative treatment.

Hybrid gold single crystals incorporating amino acids [PDF]
arXiv, 2016 Composite hybrid gold crystals are of profound interest in various research areas ranging from materials science to biology. Their importance is due to their unique properties and potential implementation, for example in sensing or in bio-nanomedicine. Here we report on the formation of hybrid organic-metal composites via the incorporation of selected ...

Denoising Score-Matching for Uncertainty Quantification in Inverse Problems [PDF]
arXiv, 2020 Deep neural networks have proven extremely efficient at solving a wide rangeof inverse problems, but most often the uncertainty on the solution they provideis hard to quantify. In this work, we propose a generic Bayesian framework forsolving inverse problems, in which we limit the use of deep neural networks tolearning a prior distribution on the ...

Decomposition of Amino Acids in Water with Application to In-Situ Measurements of Enceladus, Europa and Other Hydrothermally Active Icy Ocean Worlds [PDF]
, 2019 To test the potential of using amino acid abundances as a biosignature at icy ocean worlds, we investigate whether primordial amino acids (accreted or formed by early aqueous processes) could persist until the present time. By examining the decomposition kinetics of amino acids in aqueous solution based on existing laboratory rate data, we find that ...

Renal and Hepatic Dysfunction in Malaria Patients in Minna, North Central Nigeria [PDF]
, 2009 Information on kidney and liver involvement in malaria in Africa is still very scanty. Kidney and liver functions were assessed in 70 malaria patients using serum levels of creatinine and urea and urinary protein levels as test indicators of kidney ...

Additives Influence the Phase Behavior of Calcium Car-bonate Solution by a Cooperative Ion-association Process [PDF]
arXiv, 2019 Amorphous calcium carbonate (ACC) has been widely found in biomineralization, both as a transient precursor and a stable phase, but how organisms accurately control its formation and crystallization pathway remains unclear. Here, we aim to illu-minate the role of biologically relevant additives on the phase behaviour of calcium carbonate solution by ...

Self‐Adjusting Engineered Probiotic for Targeted Tumor Colonization and Local Therapeutics Delivery
Advanced Science, EarlyView.Zou et al. developed an engineered strain of Escherichia coli Nissle 1917 with precise targeting abilities for colonization and on‐demand payload release. The engineered probiotic survives and embolizes tumors only in the presence of more than 5 mM L‐lactate. Furthermore, the introduction of an α‐hemolysin circuit enhances its anti‐tumor effect.

Three phases in the evolution of the standard genetic code: how translation could get started [PDF]
arXiv, 2007 A primordial genetic code is proposed, having only four codons assigned, GGC meaning glycine, GAC meaning aspartate/glutamate, GCC meaning alanine-like and GUC meaning valine-like. Pathways of ambiguity reduction enlarged the codon repertoire with CUC meaning leucine, AUC meaning isoleucine, ACC meaning threonine-like and GAG meaning glutamate ...
