REVIEW
Ralph R Minter, Alan M Sandercock, Steven J Rust
The majority of antibody therapeutics have been isolated from target-led drug discovery, where many years of target research preceded drug program initiation. However, as the search for validated targets becomes more challenging and target space becomes increasingly competitive, alternative strategies, such as phenotypic drug discovery, are gaining favour. This review highlights successful examples of antibody phenotypic screens that have led to clinical drug candidates. We also review the requirements for performing an effective antibody phenotypic screen, including antibody enrichment and target identification strategies...

PURPOSE: To investigate the effect of the asymmetric gradient concomitant fields (CF) with zeroth and first-order spatial dependence on fast/turbo spin-echo acquisitions, and to demonstrate the effectiveness of their real-time compensation. METHODS: After briefly reviewing the CF produced by asymmetric gradients, the effects of the additional zeroth and first-order CFs on these systems are investigated using extended-phase graph simulations. Phantom and in vivo experiments are performed to corroborate the simulation...

Recently, laser ablated molecular isotopic spectrometry (LAMIS) has expanded its capability to explore molecules formation mechanism in laser induced plasma in addition to isotope analysis. LAMIS is powerful tool for tracking the origination of atoms that involved in formation of investigated molecules by labeling atoms with its isotopic substitution. The evolutionary formation pathways of organic molecules, especially of C2 dimers and CN radicals, were frequently reported. However, very little is known about the formation pathways for metallic radicals and heterodimers in laser ablated plasma...

BACKGROUND: The UK Kidney Fast-Track Scheme (KFTS) was introduced in 2012 to identify kidneys at high risk of discard and to rapidly facilitate transplantation. A retrospective analysis of kidneys transplanted through the KFTS was undertaken. METHODS: UK Transplant Registry data were collected on deceased donor kidneys implanted between 1 November 2012 and 30 April 2015 (DBD donors) and 1 March 2013 and 30 April 2015 (DCD donors). Posttransplant outcomes included 1-year eGFR and death-censored graft survival (DCGS)...

Heart failure (HF) is a global epidemic, with a high mortality and morbidity burden. In such diseases, earlier access to lifesaving therapeutic regimens is imperative, and could be accomplished by improving the drug development and approval process, without jeopardizing patient safety. The US Food and Drug Administration (FDA) has already established mechanisms facilitating the latter, but further guidance to enhance and expedite the process holds promise to further improve patient outcomes.

A fast-growing stalagmite from the central California coast provides a high-resolution record of climatic changes synchronous with global perturbations resulting from the catastrophic drainage of proglacial Lake Agassiz at ca. 8.2 ka. High frequency, large amplitude variations in carbon isotopes during the 8.2 ka event, coupled with pulsed increases in phosphorus concentrations, indicate more frequent or intense winter storms on the California coast. Decreased magnesium-calcium ratios point toward a sustained increase in effective moisture during the event, however the magnitude of change in Mg/Ca suggests this event was not as pronounced on the western North American coast as anomalies seen in the high northern latitudes and monsoon-influenced areas...

Replicative aging has been demonstrated in asymmetrically dividing unicellular organisms, seemingly caused by unequal damage partitioning. Although asymmetric segregation and inheritance of potential aging factors also occur in symmetrically dividing species, it nevertheless remains controversial whether this results in aging. Based on large-scale single-cell lineage data obtained by time-lapse microscopy with a microfluidic device, in this report, we demonstrate the absence of replicative aging in old-pole cell lineages of Schizosaccharomyces pombe cultured under constant favorable conditions...

A new lithographic editing system with an ability to erase and rectify errors in microscale with real-time optical feedback is demonstrated. The erasing probe is a conically shaped hydrogel (tip size, ca. 500 nm) template-synthesized from track-etched conical glass wafers. The "nanosponge" hydrogel probe "erases" patterns by hydrating and absorbing molecules into a porous hydrogel matrix via diffusion analogous to a wet sponge. The presence of an interfacial liquid water layer between the hydrogel tip and the substrate during erasing enables frictionless, uninterrupted translation of the eraser on the substrate...

'Fast-track' surgery was introduced more than 20 years ago and may be defined as a co-ordinated peri-operative approach aimed at reducing surgical stress and facilitating post-operative recovery.The fast-track programmes have now been introduced into total hip arthroplasty (THA) surgery with reduction in post-operative length of stay, shorter convalescence and rapid functional recovery without increased morbidity and mortality. This has been achieved by focusing on a multidisciplinary collaboration and establishing 'fast-track' units, with a well-defined organisational set-up tailored to deliver an accelerated peri-operative course of fast-track surgical THA procedures...

Total hip arthroplasty (THA) surgery has shown dramatic changes in terms of increased number of procedures and of technical development in recent years. It has been described as "the operation of the 20(th) century" for the excellent results, the high satisfaction of the patients and the improvement of the quality of life.A lot of variations have been introduced over the last few decades in THA especially in terms of indications (both in younger and older patients), techniques and devices (approaches, tissue preservation, biomaterials and industrial finishing), per-operative management (blood loss and pain control) and post-operative protocols (the so called "fast track" surgery)...

In the kidneys, there is both blood flow through the capillaries and flow of pre-urine through the tubuli and collecting ducts. We hypothesized that diffusion-weighted (DW) MRI measures both blood and pre-urine flow when using a tri-exponential intravoxel incoherent motion (IVIM) model. Our aim was to systematically investigate and optimize tri-exponential IVIM-analysis for the kidney and test its sensitivity to renal perfusion changes in humans. The tri-exponential fit probes the diffusion coefficient (D), the intermediate (D*i) and fast (D*f) pseudo-diffusion coefficients, and their signal fractions, fD, fi and ff...

When used in appropriate patient populations, fast-track extubation (FTE) anesthetic techniques and intensive care unit (ICU) protocols safely reduce intubation times, ICU length of stay, and resource utilization. The authors hypothesized that perioperative provider debriefing on success or failure of FTE would improve FTE success. This retrospective observational study included consecutive patients undergoing elective coronary artery bypass graft (CABG), valve, or combined CABG/valve surgery between February 2015 and May 2016 (N = 313)...

OBJECTIVE: Muscle weakness due to trauma from the surgical approach is anticipated to affect the ability of the patient to undertake daily physical activity early after total hip arthroplasty (THA). The objective of this study was to compare daily physical activity on days 1 to 4 after discharge, in patients following THA performed by 1 of 3 surgical approaches. DESIGN: A cohort study included 60 hip osteoarthritis patients, scheduled for THA, allocated to direct lateral approach, posterior approach, or anterior approach...

GENETIC COUNSELING AND PARP INHIBITORS PRESCRIPTION: Upon the availability of the PARP inhibitors in relapsed ovarian carcinoma, the pathways of the oncogenetic counseling were modified. Any research for a constitutional alteration of the BRCA1 and BRCA2 genes must be accompanied by an oncogenetic counseling. BRCA testing is recommended from the diagnosis to every woman with an ovarian or fallopian tube or peritoneum of high grade adenocarcinoma, whatever the age at the diagnosis and her family history. In case of sensitive relapse or potential inclusion in a clinical trial and in the absence of preliminary constitutional research, the oncogenetic counseling is organized according to a fast track pathway and a somatic analysis can be realized in parallel...

Determining the size distribution and composition of particles suspended in water can be challenging in heterogeneous multicomponent samples. Light scattering techniques can measure the distribution of particle sizes, but provide no basis for distinguishing different types of particles. Direct imaging techniques can categorize particles by shape, but offer few insights into their composition. Holographic characterization meets this need by directly measuring the size, refractive index, and three-dimensional position of individual particles in a suspension...

PURPOSE: The oblique-viewing (i.e., angled) rigid endoscope is a commonly used tool in conventional endoscopic surgeries. The relative rotation between its two moveable parts, the telescope and the camera head, creates a rotation offset between the actual and the projection of an object in the camera image. A calibration method tailored to compensate such offset is needed. METHODS: We developed a fast calibration method for oblique-viewing rigid endoscopes suitable for clinical use...

INTRODUCTION: Excitability properties of motor nerves to different muscles are different, but the explanation is uncertain. We characterized motor axon excitability properties to the medial gastrocnemius (MG) in 27 adults, and made comparisons with the peroneal nerve to the tibialis anterior (TA) and median nerve to the abductor pollicis brevis (APB) in 10 subjects. METHODS: Recordings of multiple excitability properties were made using threshold tracking, stimulating the nerves at the wrist or knee...

The presented optical flow metering methods are appropriate to characterise the dynamic properties of microfluidic systems. The dynamic behaviour of clinical or medical devices, micro pumps and flow sensors based on thermal methods were investigated. The Camera-System covers a flow range from 50nl/min to 500µl/min. The uncertainty is less than 4%, sample rates up to 5kS/s. The Displacement-Sensor-System covers a flow range between 100µl/min and 50ml/min. The uncertainty is less than 3% at sample rates up to 49kS/s...
