Fast protein liquid chromatography (FPLC) is a form of high-performance chromatography that takes advantage of the high resolution made possible by small-diameter stationary phases. It was originally developed for proteins and features high loading capacity, biocompatible aqueous buffer systems, fast flow rates, and availability of stationary phases in most common chromatography modes (e.g., ion exchange, gel filtration, reversed phase, and affinity). The system makes reproducible separation possible by incorporating a high level of automation including autosamplers, gradient program control, and peak collection...

Diseases caused by Streptococcus pneumoniae are a major public health problem worldwide, which can be effectively prevented by the 23-valent pneumococcal polysaccharide vaccines (PPV23). Areas covered: The Beijing Minhai PPV23 showed good safety and immunogenicity profiles in clinical trials. The immunogenicity of Beijing Minhai PPV23 was non-inferior to other licensed PPVs. Although PPV23 has been proved to be highly efficient and cost-effective, and was recommended for vaccination in high-risk populations in industrialized countries, the coverage of PPV23 vaccination was relatively low in developing countries...

Significance: Fibrosis-related events play a part in the pathogenesis or failure of treatment of virtually all the blinding diseases around the world, and also account for over 40% of all deaths. It is well established that the eye and other tissues of some group of patients, for example Afro-Caribbean people, scar worse than others. However, there is a current lack of reliable biomarkers to stratify the risk of scarring and postsurgical fibrosis in the eye. Recent Advances: Recent studies using genomics, proteomics, metabolomics, clinical phenotyping, and high-resolution in vivo imaging techniques have revealed potential novel biomarkers to identify and stratify patients at risk of scarring in different fibrotic eye diseases...

The clinical efficacy of multiple kinase inhibitors has caught the interest of Pharmaceutical and Biotech researchers to develop potential drugs with multi-kinase inhibitory activity for complex diseases. In the present work, we attempted to identify dual inhibitors of. Syk and JAK3, keys players in immune signaling, by developing ideal pharmacophores integrating Ligand based pharmacophore models (LBPMs) and Structure based pharmacophore models (SBPMs), thereby projecting the optimum pharmacophoric required for inhibition of both the kinases...

There has been growing concern about the phenomenon of science hype, the tendency to exaggerate the value or near-future application of research results. Although this is a problem that touches every area of biomedicine, the topic of genetics seems to be particularly prone to enthusiastic predictions. The world has been told for over two decades-by the media, researchers, politicians, and the biotech industry-that a genome-driven health care revolution is just around the corner. And while the revolution never seems to arrive, the hopeful rhetoric continues...

In vitro diagnostics (IVD) has huge potential. Primary drivers in the global market are the patient's awareness of infectious diseases, the introduction of advanced molecular and tissue diagnostic tests for patient-stratified and targeted anti-cancer therapy and, last but not least, the growing geriatric population. Rapid progress in device miniaturization and information technology (IT) offers new possibilities in decentralized testing. Grand View Research Inc. expects the global market for IVD to reach US $ 74...

Haemoglobinopathies may interfere with the hemoglobin A1 c (HbA1 c) measurement, leading to incorrect diagnosis and inappropriate treatment. It is essential that HbA1 c assays are capable of identifying haemoglobinopathies. We report two cases of haemoglobin New York (HbNY) discovered through HbA1 c analysis using capillary electrophoresis (Capillarys 2 Flex Piercing [C2FP], Sebia). We used these samples to evaluate the ability of three other HbA1 c assays to identify this variant: ion-exchange high performance liquid chromatography (HPLC; Variant II Turbo [VII-T], Bio-Rad); boronate affinity HPLC (Ultra(2), Trinity Biotech); and immunoassay (cobas c501 Tina-quant Generation 3, Roche Diagnostics)...

We focus here on how the interface in academia has adapted in their approach to assessing the PDs of biological agents to better understand mechanisms at an early stage. This understanding enables drugs to be modified early and to be reassessed before progressing to late stage trials. We discuss how these efforts are now being bolstered by a network of consortia involving industry, academia and regulatory bodies, to bring together resources, knowledge and a harmonization in bioanalytical techniques. We highlight how the regulatory guidance still lags behind the rapid advancement in biologicals and associated analytical techniques, especially in immunotherapies and immunological bioassays...

A new type of medicine was approved in Europe at the end of May that culminated from the successful convergence of two fields of science: stem cell transplantation and gene therapy. Strimvelis, a patient-specific gene-modified stem cell medicine for ADA-SCID (a fatal immunometabolic disorder similar to the bubble-boy disease), was developed by scientists at the San Raffaele Telethon Institute for Gene Therapy (TIGET) in Milan, then later partnered with GSK. The journey took over 25 years of dedicated work from many groups and involved a pivotal trial with 12 children and their brave families...
