Detection of protein-binding analytes is important for many applications. Currently, various instrument-based techniques are used for detecting protein-binding analytes. However, such techniques have several limitations including high cost and time-consuming sample processing. In order to overcome these limitations, we developed a sensitive competition assay for the detection of protein-binding analytes using recombinant endospores as a sensing element. The method is based on the competition between the biotin, the model analyte, and a biotin-magnetic bead complex to bind the recombinant spores containing the biotin binding region of streptavidin. After magnetic attraction, the residual spores in the suspension are spread on plates to form colonies which are used to count the amount of the residual spores; the higher the residual ratio of spores, the more biotin in the samples. The linear range was from 150 zmol to 1.5 fmol and the limit of detection of the assay was 150 zmol. The assay proposed herein is sensitive and does not require any expensive equipment. Ripasudil It is suitable for qualitative or semi-quantitative analysis such as screening tests for the detection of toxic chemicals.
To evaluate the value of synthetic magnetic resonance imaging (MRI) and T2 mapping in distinguishing between different types of fillers in soft tissues.

Ex vivo fillers of buttock soft tissues (silicone, collagen, and different types of hyaluronic acid) were scanned using a synthetic MRI sequence at 1.5 and 3T and an optimized T2 mapping sequence to measure the T2 relaxation times of the fillers ex vivo. Three patients addressed to assess complications with buttock fillers underwent MRI with the standard morphological sequences and an additional synthetic MRI sequence; T2 mapping was not performed for the patients. Two patients had silicone fillers, whereas the exact filler composition for the third patient was unknown.

Measurements of T1 and T2 relaxation times of ex vivo fillers at 1.5 and 3T using synthetic MRI showed that the silicone, collagen, and hyaluronic acid had distinct relaxation time characteristics. In vivo, the synthetic MRI correctly identified silicone in the two patients with known silicone fillers, showing low T1 and T2 values, whereas in the third patient with an unknown filler type, the synthetic MRI suggested a collagen filler, with intermediate relaxation time values.

Quantitative sequences have the potential to differentiate between filler types in a noninvasive fashion.

Such changes are usually accompanied by a loss of entropy by the protein, and thus conformational changes are integral to the thermodynamics of ligand association. Methods to detect these alterations are numerous; here, we focus on the sedimentation velocity (SV) mode of AUC, which has several advantages, including ease of use and rigorous data-selection criteria. In SV, it is assumed that conformational changes manifest primarily as differences in the sedimentation coefficient (the s-value). Two methods of determining s-value differences were assessed. The first method used the widely adopted c(s) distribution to gather statistics on the s-value differences to determine whether the observed changes were reliable. In the second method, a decades-old technique called "difference SV" was revived and updated to address its viability in this era of modern instrumentation. Both methods worked well to determine the extent of conformational changes to three model systems. Both simulations and experiments were used to explore the strengths and limitations of the methods. Finally, software incorporating these methodologies was produced.Accurate diagnosis, monitoring and treatment decisions in patients with chronic liver disease currently rely on biopsy as the diagnostic gold standard, and this has constrained early detection and management of diseases that are both varied and can be concurrent. Recent developments in multiparametric magnetic resonance imaging (mpMRI) suggest real potential to bridge the diagnostic gap between non-specific blood-based biomarkers and invasive and variable histological diagnosis. This has implications for the clinical care and treatment pathway in a number of chronic liver diseases, such as haemochromatosis, steatohepatitis and autoimmune or viral hepatitis. Here we review the relevant MRI techniques in clinical use and their limitations and describe recent potential applications in various liver diseases. We exemplify case studies that highlight how these techniques can improve clinical practice. These techniques could allow clinicians to increase their arsenals available to utilise on patients and direct appropriate treatments.The writer Bertolt Brecht (1898-1956) is known for his poems, dramas and the "epic or dialectical theater" he founded. He was retrospectively postulated to have had rheumatic fever because of heart problems and neuromuscular symptoms in his youth. Based on current rheumatological knowledge, it cannot be deduced with certainty from the available documents that Brecht had rheumatic fever. At most, a very unusual manifestation of rheumatic fever can be suspected with atypical rheumatic chorea and a very atypical course of rheumatic carditis. Several deviations from the classical clinical picture-the absence of fever and arthritis, no typical symptoms of Sydenham's chorea, the lack of a diagnosis of heart valve defects in adolescence-lead to extensive differential diagnostic considerations. A possible psychosomatic origin through functional heart complaints must even be postulated if a temporary previous organic cause cannot be excluded. Only the use of the advanced diagnostics available today with Doppler sonography of the heart, cardiac magnetic resonance imaging (MRI), throat swabs for Streptococci and streptococcal serology would have made it possible to diagnose Brecht's cardiac symptoms in his adolescence without a doubt and to differentiate them from functional heart complaints. His death is verified by medical documents clearly documenting bacterial endocarditis with evidence of coli bacteria caused by urological interventions with subsequent febrile episodes and pyelonephritis.
