description: Background: The purpose of this paper is to outline my experiences investigating the need for additional support among post-concussion patients and their families. A growing volume of research has continued to demonstrate the significant health consequences of concussions on youth and adolescents, with studies emphasizing the need for increased support during the post-concussion recovery period. It was proposed that one way to provide this support may be through family-based peer support. Results: In this study, I interviewed 25 families with a child who had experienced a concussion in the past two years and received care from BCCH. The findings showed that individuals from this sample typically reported that they did not need additional support. While additional support was not indicated for this sample, it is important to note that all participants reported their concussion symptoms had resolved within a month. Conclusions: Results may have differed in a population with longer-lasting or more severe concussion symptoms. Additionally, this paper outlines my experience with conducting research during a global pandemic, additional findings regarding education surrounding concussions, and suggestions for future research.

description: We propose a new multiscale method to calculate the amplitude of the gradient of the linear polarisation vector using a wavelet-based formalism. We demonstrate this method using a field of the Canadian Galactic Plane Survey (CGPS) and show that the filamentary structure typically seen in gradients of linear polarisation maps depends strongly on the instrumental resolution. Our analysis reveals that different networks of filaments are present on different angular scales. The wavelet formalism allows us to calculate the power spectrum of the fluctuations seen in gradients of linear polarisation maps and to determine the scaling behaviour of this quantity. The power spectrum is found to follow a power law with gamma ~ 2.1. We identify a small drop in power between scales of 80 < l < 300 arcmin, which corresponds well to the overlap in the u-v plane between the Effelsberg 100-m telescope and the DRAO 26-m telescope data. We suggest that this drop is due to undersampling present in the 26-m telescope data. In addition, the wavelet coefficient distributions show higher skewness on smaller scales than at larger scales. The spatial distribution of the outliers in the tails of these distributions creates a coherent subset of filaments correlated across multiple scales, which trace the sharpest changes in the polarisation vector P within the field. We suggest that these structures may be associated with highly compressive shocks in the medium. The power spectrum of the field excluding these outliers shows a steeper power law with gamma ~ 2.5.

description: The catalogue of soft-bottom macrofauna in the Marennes-Oléron Bay (French Atlantic coast) has been updated
 from a benthic survey conducted in April-May 1995. 262 stations were selected using a stratified random strategy based on
 sediment types and bathymetric levels. 231 soft-bottom macrofauna species were identified. A synopsis of all available
 literature since the first local marine study published in 1710 by Antoine Ferchauld de Réaumur indicated that 60 benthic
 species were reported in the Marennes-Oléron Bay for the first time. The sampling effort, i.e. more than 1 station per km2
 and size of the sieving square mesh (1 mm), can partially explain these results. Most of the new recorded species were
 crustaceans (28 species) and polychaete annelids (25 species) for only five molluscs. First report of Ocinebrellus inornatus,
 Mollusca Gastropoda, should be noted for the European Atlantic coasts. Additionally, alteration of subtidal habitats,
 colonized by Crepidula fornicata Linnaeus (Mollusca, Gastropoda) since the 1970's, may also have facilitated the
 recruitment and spread of some annelid polychaetes which were not previously reported in the Marennes-Oléron Bay. The
 total number of macrofauna species in the Pertuis Charentais Sea is 858.

Interaction between the basolateral K+ and apical Na+ conductances in Necturus urinary bladder
Creators: name: Finn, Arthur L.
name: Demarest, Jeffery R.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1987

description: Experimental modulation of the apical membrane Na+ conductance or basolateral membrane Na+-K+ pump activity has been shown to result in parallel changes in the basolateral K+ conductance in a number of epithelia. To determine whether modulation of the basolateral K+ conductance would result in parallel changes in apical Na+ conductance and basolateral pump activity, Necturus urinary bladders stripped of serosal muscle and connective tissue were impaled through their basolateral membranes with microelectrodes in experiments that allowed rapid serosal solution changes. Exposure of the basolateral membrane to the K+ channel blockers Ba2+ (0.5 mM/liter), Cs+ (10 mM/liter), or Rb+ (10 mM/liter) increased the basolateral resistance (Rb) by greater than 75% in each case. The increases in Rb were accompanied simultaneously by significant increases in apical resistance (Ra) of greater than 20% and decreases in transepithelial Na+ transport. The increases in Ra, measured as slope resistances, cannot be attributed to nonlinearity of the I-V relationship of the apical membrane, since the measured cell membrane potentials with the K+ channel blockers present were not significantly different from those resulting from increasing serosal K+, a maneuver that did not affect Ra. Thus, blocking the K+ conductance causes a reduction in net Na+ transport by reducing K+ exit from the cell and simultaneously reducing Na+ entry into the cell. Close correlations between the calculated short-circuit current and the apical and basolateral conductances were preserved after the basolateral K+ conductance pathways had been blocked. Thus, the interaction between the basolateral and apical conductances revealed by blocking the basolateral K+ channels is part of a network of feedback relationships that normally serves to maintain cellular homeostasis during changes in the rate of transepithelial Na+ transport.

Field Generator for INSPECT with optimized Cooling

name: Lüdtke-Buzug, Kerstin
Publisher: name: Transactions on Additive Manufacturing Meets Medicine
Year: 2022

description: Additive manufacturing has proved to be an excellent methodology for rapid prototyping of required components used in scientific setups. In the past few years, there has been an immense improvement in the physical properties of the printing material making it possible to have high thermal resistivity with required tensile strength. In this research, the focus is on the design and development of the field generator housing for INSPECT (In-situ magnetic particle spectrometer) [1]. The field generator for INSPECT consists of a transmit coil and a gradiometer coil. The transmit coil is responsible for generating the field required to excite the magnetic nanoparticles. The gradiometer coil contains two different coils: the cancellation coil and the receive coil for acquiring the response of the magnetic particles and separating it from the excitation signal. The field generator of INSPECT is designed to monitor the real-time nucleation and growth of SPIONs, therefore must withstand a change in temperature depending upon the synthesis process. The housing for the field generator is designed using SolidWorks 2020 from Dassault Systèmes in France and 3D printed using Form 3B from Formlabs Inc. in the USA. The material used for printing is a High-Temp Resin from Formlabs Inc., with a heat deflection temperature (HDT) of 238 °C at 0.45 MPa [2]. To prevent excessive heating of the transmit coil, the housing contains small cooling-channels which allow air to across the surface of the coil. Additionally, the housing also accommodates Polyethylene tubes which are placed concentrically around the transmit coil. Coolant can be passed through these tubes to achieve additional cooling of the transmit coil using a feedback loop depending on the synthesis temperature. Furthermore, the field generator is insulated with the help of an 8 mm nonporous aerogel insulation for thermal resistivity against synthesis temperature [3]. Therefore, the housing offers a versatile solution in terms of keeping the coil temperature in check irrespective of the external temperature conditions arising due to magnetic nanoparticle synthesis. The high complexity of the housing makes use of the potential of additive manufacturing and would not be possible by conventional means.

Search for supersymmetry with a photon, a lepton, and missing transverse momentum in pp collisions at sqrt(s) = 8 TeV

Year: 2015
Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: A search for supersymmetry involving events with at least one photon, one electron or muon, and large missing transverse momentum has been performed by the CMS experiment. The data sample corresponds to an integrated luminosity of 19.7 inverse femtobarns of pp collisions at sqrt(s) = 8 TeV, produced at the CERN LHC. No excess of events is observed beyond expectations from standard model processes. The result of the search is interpreted in the context of a general model of gauge-mediated supersymmetry breaking, where the charged and neutral winos are the next-to-lightest supersymmetric particles. Within this model, winos with a mass up to 360 GeV are excluded at the 95% confidence level. Two simplified models inspired by gauge-mediated supersymmetry breaking are also examined, and used to derive upper limits on the production cross sections of specific supersymmetric processes.

Interactions of sodium transport, cell volume, and calcium in frog urinary bladder
Creators: name: Finn, Arthur L.
name: William Davis, C.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1987

description: The volume of individual cells in intact frog urinary bladders was determined by quantitative microscopy and changes in volume were used to monitor the movement of solute across the basolateral membrane. When exposed to a serosal hyposmotic solution, the cells swell as expected for an osmometer, but then regulate their volume back to near control in a process that involves the loss of KCl. We show here that volume regulation is abolished by Ba++, which suggests that KCl movements are mediated by conductive channels for both ions. Volume regulation is also inhibited by removing Ca++ from the serosal perfusate, which suggests that the channels are activated by this cation. Previously, amiloride was observed to inhibit volume regulation: in this study, amiloride-inhibited, hyposmotically swollen cells lost volume when the Ca++ ionophore A23187 was added to Ca++-replete media. We attempted to effect volume changes under isosmotic conditions by suddenly inhibiting Na+ entry across the apical membrane with amiloride, or Na+ exit across the basolateral membrane with ouabain. Neither of these Na+ transport inhibitors produced the expected results. Amiloride, instead of causing a decrease in cell volume, had no effect, and ouabain, instead of causing cell swelling, caused cell shrinkage. However, increasing cell Ca++ with A23187, in both the absence and presence of amiloride, caused cells to lose volume, and Ca++-free Ringer's solution (serosal perfusate only) caused ouabain-blocked cells to swell. Finally, again under isosmotic conditions, removal of Na+ from the serosal perfusate caused a loss of volume from cells exposed to amiloride. These results strongly suggest that intracellular Ca++ mediates cell volume regulation by exerting a negative control on apical membrane Na+ permeability and a positive control on basolateral membrane K+ permeability. They also are compatible with the existence of a basolateral Na+/Ca++ exchanger.

description: Ultracold gases promise access to many-body quantum phenomena at convenient length and time scales. However, it is unclear whether the entropy of these gases is low enough to realize many phenomena relevant to condensed matter physics, such as quantum magnetism. Here we report reliable single-shot temperature measurements of a degenerate $^{87}$Rb gas by imaging the momentum distribution of thermalized magnons, which are spin excitations of the atomic gas. We record average temperatures as low as $0.022(1)_\text{stat}(2)_\text{sys}$ times the Bose-Einstein condensation temperature, indicating an entropy per particle, $S/N\approx0.001\, k_B$ at equilibrium, that is well below the critical entropy for antiferromagnetic ordering of a Bose-Hubbard system. The magnons themselves can reduce the temperature of the system by absorbing energy during thermalization and by enhancing evaporative cooling, allowing low-entropy gases to be produced within deep traps.

BRYOZOA (POLYZOA) FROM THE SOUTH RED SEA
Creators: name: POWELL, N. A.
Publisher: name: Station Biologique de Roscoff (SBR)
Year: 1967

description: Thirty species of Bryozoa are documented here from the vicinity of Port Massawa, South Red Sea. One species viz. Drepanophora birbira is described as new. Bryozoans were more commonly found associated with coral reefs from three to twenty fathoms, encrusting molluscan shells and coral. The following species are new to the Red Sea fauna: Membranipora tuberculata, Antropora marginella, Conopeum commensale, Steganoporella simplex, Schizomavella australis, Hippopodinella feegeensis, Hippaliosina acutirostris, Hippopodinella adpressa, Smittina malleolus, Parasmittina glomerata, Cleidochasma laterale, Rhynchozoon globosum. Scrutiny of the literature shows that a substantial portion of the Sudanese Red Sea bryozoan material (Waters 1909, 1910) has been verified specifically by subsequent workers. The distribution of those species is given here. These data indicate that the Red Sea bryozoan fauna 1) contains few indigenous species, 2) lacks a significant representation of Mediterranean species, 3) is dominated by exclusively Indo-Pacific species. The conclusions reached here are in close agreement with the evidence obtained from some other Red Sea invertebrate groups for which significant data are available.

description: Establishing the relative role of internally and externally driven mechanisms responsible for disc and bulge growth is essential to understand the evolution of disc galaxies. In this context, we have studied the physical properties of disc galaxies without classical bulges in comparison to those with classical bulges since z~0.9. Using images from the Hubble Space Telescope and Sloan Digital Sky Survey, we have computed both parametric and non-parametric measures, and examined the evolution in size, concentration, stellar mass, effective stellar mass density and asymmetry. We find that both disc galaxies with and without classical bulges have gained more than 50% of their present stellar mass over the last ~8 Gyrs. Also, the increase in disc size is found to be peripheral. While the average total (Petrosian) radius almost doubles from z~0.9 to z~0, the average effective radius undergoes a marginal increase in comparison. Additionally, increase in the density of the inner region is evident through the evolution of both concentration and effective stellar mass density. We find that the asymmetry index falls from higher to lower redshifts, but this is more pronounced for the bulgeless disc sample. Also, asymmetry correlates with the global effective radius, and concentration correlates with the global Sersic index, but better so for higher redshifts only. The substantial increase in mass and size indicates that accretion of external material has been a dominant mode of galaxy growth, where the circumgalactic environment plays a significant role.

description: As a promising paradigm for fifth generation (5G) wireless communication systems, cloud radio access networks (C-RANs) have been shown to reduce both capital and operating expenditures, as well as to provide high spectral efficiency (SE) and energy efficiency (EE). The fronthaul in such networks, defined as the transmission link between a baseband unit (BBU) and a remote radio head (RRH), requires high capacity, but is often constrained. This article comprehensively surveys recent advances in fronthaul-constrained C-RANs, including system architectures and key techniques. In particular, key techniques for alleviating the impact of constrained fronthaul on SE/EE and quality of service for users, including compression and quantization, large-scale coordinated processing and clustering, and resource allocation optimization, are discussed. Open issues in terms of software-defined networking, network function virtualization, and partial centralization are also identified.

Cytosolic protein concentration is the primary volume signal in dog red cells

description: It is not known whether the activation of Na/H exchange by shrinkage in dog red cells is due to the packing of cell contents or a change in cell configuration. To make this distinction we prepared resealed ghosts that resembled intact cells in hemoglobin concentration and surface area, but had one-third their volume. A shrinkage-induced, amiloride-sensitive Na flux in the ghosts was activated at a much smaller volume in the ghosts than in the intact cells, but at the same concentration (by weight) of dry solids in both preparations. Na/H exchange in ghosts containing a mixture of 40% albumin and 60% hemoglobin (weight/weight) was activated by osmotic shrinkage at a dry solid concentration similar to that of intact cells or of ghosts containing only hemoglobin. We conclude that the process of Na/H exchange activation by cell shrinkage originates with an increase in the concentration of intracellular protein and not with a change in membrane configuration or tension. The macromolecular crowding that accompanies the reduction in cell volume probably alters the activities of key enzymes that in turn modulate the Na/H exchanger.

The method involves subjecting the excitons to a periodic electrostatic potential that causes modulations of the exciton density and photoluminescence (PL). Experimentally measured amplitudes of energy and intensity modulations of exciton PL serve as an input to a theoretical estimate of the exciton correlation parameter and temperature. We also present a proof-of-principle demonstration of the method for determining the correlation parameter and discuss how its accuracy can be improved.

description: We have previously shown that monoclonal antibody E12 (MAb E12), one of several such antibodies raised against theophylline-treated Necturus gallbladder (NGB) epithelial cells, inhibits the chloride conductance in the apical membrane of that tissue. Since chloride channels are critical to the secretory function of epithelia in many different animals, we have used this antibody to determine whether the channels are conserved, and in an immunoaffinity column to isolate the channel protein. We now demonstrate that MAb E12 cross-reacts with detergent- solubilized extracts of different tissues from various species by enzyme-linked immunosorbent assay (ELISA). Western blot analysis shows that this monoclonal antibody recognizes proteins of Mr 219,000 in NGB, toad gallbladder, urinary bladder, and small intestine, A6 cells, rat colon, rabbit gastric mucosa, human lymphocytes, and human nasal epithelial cells, and inhibits the chloride conductance in toad gallbladder, rat colon, and human nasal epithelium. Detergent- solubilized protein eluted from an immunoaffinity column and then further purified via FPLC yields a fraction (Mr 200,000-220,000) which has been reconstituted into a planar lipid bilayer. There it behaves as a chloride-selective channel (PCl/PNa = 20.2 in a 150/50 mM trans- bilayer NaCl gradient) whose unit conductance is 62.4 +/- 4.6 pS, and which is blocked in the bilayer by the antibody. The gating characteristics of this channel indicate that it can exist as aggregates or as independent single channels, and that the antibody interferes with gating of the aggregates, leaving the unit channels unchanged. From these data we conclude that the protein of Mr 219,000 recognized by this monoclonal antibody is an important component of an epithelial chloride channel, and that this channel is conserved across a wide range of animal species.

To differentiate between these two alternatives we prepared resealed ghosts that, compared with intact red cells, had the same surface area and similar hemoglobin concentration, but a greatly diminished volume. Swelling-induced [K-Cl] cotransport was activated in the ghosts at a volume (20 fl) well below the activation volume for intact cells (70 fl), but at a similar hemoglobin concentration (30-35 g dry solids per 100 g wet weight). Ghosts made to contain 40% albumin and 60% hemoglobin showed activation of [K-Cl] cotransport at a concentration of cell solids similar to intact cells or ghosts containing only hemoglobin. [K-Cl] cotransport in the resealed ghosts became quiescent at a dry solid concentration close to that at which shrinkage-induced Na/H exchange became activated. These results support the notion that the primary volume sensor in dog red cells is cytosolic protein concentration. We speculate that macromolecular crowding is the mechanism by which cells initiate responses to volume perturbation.

description: The European sardine Sardina pilchardus (Walbaum, 1792) was sampled monthly (October 2000-September 2002), onboard the purse-seine fleet, at its main fishing ground (northern Aegean Sea) of the eastern Mediterranean Sea. Sardine's total length ranged from 9.1 to 17.3 cm. Ageing analysis showed that the lifespan of sardine in the area may reach 5 years. The two growth estimation equations were applied to the same dataset and produced slightly different growth parameter values (von Bertalanffy: L∞ = 17.21 cm, Κ = 0.53 y-1, t0 = -1.28 y for females and L∞ = 16.59 cm, Κ = 0.65 y-1, t0 = -1.22 y for males; Gompertz: L∞ = 17.14 cm, Κ = 0.61 y-1, t0 = -0.86 y for females and L∞ = 16.51 cm, Κ = 0.71 y-1, t0 = -0.78 y for males). Overall sex ratio was skewed towards females (F:M = 1.43, χ2 = 150.9, P < 0.001) and differed among months and size classes. The different growth patterns are explained by natural mortality that was higher for males (1.4 y-1) than for females (1.2 y-1). Although size at maturity was lower for males (11.37 cm) than for females (11.65 cm), the LM/L∞ ratio was similar (0.69 for males and 0.68 for females). Sardine's spawning in the northern Aegean occurs between October and March-April but the exact onset and duration of spawning may differ inter-annually as a result of environmental factors.

Effects of local anesthetics on single channel behavior of skeletal muscle calcium release channel

description: The effects of the two local anesthetics tetracaine and procaine and a quaternary amine derivative of lidocaine, QX314, on sarcoplasmic reticulum (SR) Ca2+ release have been examined by incorporating the purified rabbit skeletal muscle Ca2+ release channel complex into planar lipid bilayers. Recordings of potassium ion currents through single channels showed that Ca(2+)- and ATP-gated channel activity was reduced by the addition of the tertiary amines tetracaine and procaine to the cis (cytoplasmic side of SR membrane) or trans (SR lumenal) side of the bilayer. Channel open probability was lowered twofold at tetracaine and procaine concentrations of approximately 150 microM and 4 mM, respectively. Hill coefficients of 2.0 and greater indicated that the two drugs inhibited channel activity by binding to two or more cooperatively interacting sites. Unitary conductance of the K(+)- conducting channel was not changed by 1 mM tetracaine in the cis and trans chambers. In contrast, cis millimolar concentrations of the quaternary amine QX314 induced a fast blocking effect at positive holding potentials without an apparent change in channel open probability. A voltage-dependent block was observed at high concentrations (millimolar) of tetracaine, procaine, and QX314 in the presence of 2 microM ryanodine which induced the formation of a long open subconductance. Vesicle-45Ca2+ ion flux measurements also indicated an inhibition of the SR Ca2+ release channel by tetracaine and procaine. These results indicate that local anesthetics bind to two or more cooperatively interacting high-affinity regulatory sites of the Ca2+ release channel in or close to the SR membrane. Voltage-dependent blockade of the channel by QX314 in the absence of ryanodine, and by QX314, procaine and tetracaine in the presence of ryanodine, indicated one low-affinity site within the conduction pathway of the channel. Our results further suggest that tetracaine and procaine may primarily inhibit excitation-contraction coupling in skeletal muscle by binding to the high-affinity, regulatory sites of the SR Ca2+ release channel.
REPRODUCTION ASEXUEE ET CYCLE EVOLUTIF DE L'ASCIDIE DISTAPLIA UNIGERMIS

Year: 1967

description: 1. In Distaplia unigermis, as in oth~r ascidians belonging to this genus, the primordial bud separates at the end of embryonic development as an evagination of ventral ecloderm, which is entered by the distal end of the left epicard and a group of mesenchyme cells. The organogenesis begins in it: the dorsal
tube separates from the inner epithelial vesicle; the vesicle itself differentiates into the rudiments of branchial sac, gut and two epicards. The anterior and posterior ends, the dorsal and ventral sides are well cxpressed morphologically at this stage. The primordial bud is interprcted as the first generation of
blastozooids, that does not reach full development.
2. The primordial bud elongates and di vides into three parts. The two anterior fragments include the parts of the outer epidermis, the inner vesicle, the dorsal tube and mesenchyme. Besides these the posterior fragment includes the rudiments of gut and epicards. During the next embryogenesis the two anterior fragments do not show any visible complication, but the postcrior one continues its ontogenesis and becomes the rudiments of blastozooid. At the stage of free-swimming larva the rudiments of peribranchial cavities, oesophagus, stomach, intestine, intestinal gland, heart and epicards arc already distinguished
in it.
3. Oozooid, developing from the metamorphosing larva, lives about 7-11 days. During this period, the number of buds increases up to 15-20 as a result of the next fragmentation of two anterior fragments of the primordial bud. A part of arising by that way new fragments begins to develop into blastozooids. There are placenta-like structures formed by the test vessels of the oozooid and blastozooids, supplying the blastozooids with nourishment. 1-3 of the secondary blastozooids reach the full development and begin to function when oozooid is still alive. The phagocytes play an active role in the resorption of degenerating oozooid.
4. The beginning of colony formation is traced. The functionning blastozooids are capable only of th

description: To understand the nature of the transmission process of excitation- contraction (EC) coupling, the effects of the anion perchlorate were investigated on the voltage sensor (dihydropyridine receptor, DHPR) and the Ca release channel (ryanodine receptor, RyR) of the sarcoplasmic reticulum (SR). The molecules, from rabbit skeletal muscle, were either separated in membrane vesicular fractions or biochemically purified so that the normal EC coupling interaction was prevented. Additionally, the effect of ClO4- was investigated on L-type Ca2+ channel gating currents of guinea pig ventricular myocytes, as a native DHPR not in the physiological interaction of skeletal muscle. At 20 mM, ClO4- had minor effects on the activation of ionic currents through Ca channels from skeletal muscle transverse tubular (T) membranes fused with planar bilayers: a +7-mV shift in the midpoint voltage, V, with no change in kinetics of activation or deactivation. This is in contrast with the larger, negative shift that ClO4- causes on the distribution of intramembrane charge movement of skeletal muscle. At up to 100 mM it did not affect the binding of the DHP [3H]PN200-110 to triad-enriched membrane fractions (TR). At 8 mM it did not affect the kinetics or the voltage distribution of gating currents of Ca channels in heart myocytes. These negative results were in contrast to the effects of ClO4- on the release channel. At 20 mM it increased several-fold the open probability of channels from purified RyR incorporated in planar bilayers and conducting Ba2+, an effect seen on channels first closed by chelation of Ca2+ or by the presence of Mg2+. It significantly increased the initial rate of efflux of 45Ca2+ from TR vesicles (by a factor of 1.75 at 20 mM and 4.5 at 100 mM). ClO4- also increased the binding of [3H]ryanodine to TR fractions. The relative increase in binding was 50-fold at the lowest [Ca2+] used (1 microM) and then decayed to much lower values as [Ca2+] was increased. The increase was due entirely to an increase in the association rate constant of ryanodine binding. The chaotropic ions SCN- and I- increased the association rate constant to a similar extent. The binding of ryanodine to purified RyR protein reconstituted into liposomes had a greater affinity than to TR fractions but was similarly enhanced by ClO4-. The reducing agent dithiothreitol (5 mM) did not reduce the effect of ClO4- , and 5% polyethylene glycol, with an osmolarity equivalent to 20 mM ClO4-, did not change ryanodine binding.(ABSTRACT TRUNCATED AT 400 WORDS)

description: Spinal cord injury (SCI) can lead to the dysfunction of nerve fibers by hemi- or complete transection, resulting in permanent paraplegia. In recent years, a number of therapies have been developed to treat spinal cord injury. A mechanical microconnector system (mMS) that supports the regeneration of nerve fibers after SCI through a combination of different therapies was designed in previous works. For this implantable mMS with minimum feature size of a few hundreds of micrometers, it is essential to provide fast, flexible, three-dimensional fabrication. This paper describes a new fabrication method of the mMS made of silicone using additive manufacturing based on a commercially available material jetting printer. The application of this technology advances the fabrication and adaptability of mMS in terms of higher elasticity of the implant using silicone and additionally with respect to high customizability and rapid prototyping using additive manufacturing. We show the successful adaption and realization of a silicone-based mMS dimensioned for a human model with structure sizes down to 300 um. We elaborate the advantages and disadvantages of additive, silicone-based 3D printing for this application in comparison to molding-based and subtractive 3D printing methods, thus demonstrating the relevance of this technology for medical application.
