New industries develop in increasingly globalized networks, whose dynamics are not well understood by academia and policy making. Solar photovoltaics (PV) are a case in point for an industry that experienced several shifts in its spatial organization over a short period of time. A lively debate has recently emerged on whether the spatial dynamics in new cleantech sectors are in line with existing
An efficient method to form 3D superlattices of gold nanoparticles inside oil emulsion droplets is presented. We demonstrate that this method relies on Ostwald ripening, a well-known phenomenon occurring during the aging of emulsions. The key point is that the nanoparticle concentration inside the smaller droplets is increasing very slowly with time, thus inducing the crystallization of the nanopa
Single-incision laparoscopic appendectomy (SILA) has gained popularity in children, and several different techniques have been described, including intracorporeal and extracorporeal techniques and single-channel and multi-channel single-port techniques. However, there has been a concern that exteriorizing an infected appendix through the umbilical channel would increase the risk of postoperative w
Anterior cruciate ligament (ACL) injury and patellofemoral pain (PFP) are common sports-related knee injuries. Their consequences include compromised health of the effected individual and substantial financial costs for society. Increased knee abduction or a knee medial to foot position (KMFP), so called “kissing knees”, during weight-bearing activities is reported to be more common in patients wi
We compare the industrial dynamics in the core, semi-periphery and periphery in the Netherlands in terms of firm entry-exit, size, growth and location patterns. The contribution of our work is to provide the first comprehensive study on spatial differentiation in industrial dynamics for all firm sizes and all sectors, including services. We find that location patterns are largely consistent with t
A 2-year-old boy underwent an uneventful transanal endorectal pull-through for Hirschsprung's disease. Postoperatively he suffered from pneumaturia which prompted surgical evaluation. He was found to have a rectum to seminal vesicle fistula. He was re-operated closing the fistula through an anterior transperineal approach with a successful operative outcome.
We have recently discovered that the ZZ zinc finger domain represents a novel small ubiquitin-like modifier (SUMO) binding motif. In this study we identify the binding epitopes in the ZZ domain of CBP (CREB-binding protein) and SUMO1 using NMR spectroscopy. The binding site on SUMO1 represents a unique epitope for SUMO interaction spatially opposite to that observed for canonical SUMO interaction
The aim of this report is to present a technical detail of use in the management of an anorectal malformation (ARM). A boy with ARM and a fistula to the urethra was operated on with a posterior sagittal anorectoplasty (PSARP). Before the PSARP operation, a videoendoscopy was performed through the distal stoma down to the distal end of the rectum. The rectourethral fistula was identified and a guid
Acoustophoresis is a technique that applies ultrasonic standing wave forces in a microchannel to sort cells depending on their physical properties in relation to the surrounding media. Cell handling and separation for research and clinical applications aims to efficiently separate specific cell populations. Here, we investigated the sorting of CD8 lymphocytes from peripheral blood progenitor cell
Biomass burning impacts vegetation dynamics, biogeochemical cycling, atmospheric chemistry, and climate, with sometimes deleterious socio-economic impacts. Under future climate projections it is often expected that the risk of wildfires will increase. Our ability to predict the magnitude and geographic pattern of future fire impacts rests on our ability to model fire regimes, using either well-fou
The widespread growth of reefs formed by a framework of biogenic constructors and frame-lacking carbonate mounds began on Baltica during Ordovician time. Previously, Ordovician reef and mound development on Baltica was considered to be sporadic and local. A review of all known bioherm localities across the Baltic Basin reveals a more consistent pattern. Ordovician bioherms grew in a wide E–W-align
We demonstrate a new screening method for obtaining a prostate-specific antigen (PSA) binding aptamer based on an acoustofluidic separation (acoustophoreis) technique. Since acoustophoresis provides simultaneous washing and separation in a continuous flow mode, we efficiently obtained a PSA binding aptamer that shows high affinity without any additional washing step, which is necessary in other sc
Based upon the results of repeated psychologic tests, psychic impairment following myelography has been studied in 60 patients. Thirty of these had lumbar myelography with metrizamide and 30 with iohexol. Psychic impairment was noted in both groups, although with a higher frequency and much more marked in the group which had metrizamide myelography. For this type of examination iohexol is thus to
Melanocortin therapy by using adrenocorticotropic hormone (ACTH) or non-steroidogenic melanocortin peptides attenuates proteinuria and glomerular injury in experimental glomerular diseases and induces remission of nephrotic syndrome in patients with diverse glomerulopathies, even those resistant to steroids. The underlying mechanism remains elusive, but the role of melanocortin 1 receptor (MC1R) h
The benefits of kHz lidar in ecological entomology are explained. Results from kHz-measurements on insects, carried out with a CW-lidar system, employing the Scheimpflug principle to obtain range resolution, are presented. A method to extract insect events and analyze the large amount of lidar data is also described.
