We describe a case of arteriovenous fistula (AVF) successfully treated by coil embolization with an anchor coil inserted in the varix to facilitate dense packing at the shunting site. AVF of the left anterior choroidal artery (AChoA) draining into the ipsilateral basal vein of Rosenthal was incidentally found in a newborn female. A single detachable coil was inserted as an anchor into the varix adjacent to the shunt, and the microcatheter was pulled back to the shunting point. Three more detachable coils were delivered at the shunting point without migration under the support of the anchor coil, and the AVF was successfully obliterated with preservation of AChoA blood flow. The anchor coil technique can reduce the risk of coil migration and the number of coils required.

Stent-assisted coiling offers a potential solution for coil embolization of broad-based aneurysms. Challenges associated with navigating a microcatheter beyond these aneurysms sometimes require looping the microcatheter within the aneurysm dome. Reducing microcatheter loops within domes can be difficult, and anchor techniques have been described, including balloon anchor, stent-retriever anchor, and stent anchor techniques. The authors present a patient requiring stent-assisted coiling of an anterior communicating artery aneurysm in whom a stent anchor technique was used to reduce a microcatheter loop within an aneurysm dome before coil embolization. Postembolization angiographic runs showed complete coil occlusion of the aneurysm with approximately 35% packing density.The video can be found here: https://youtu.be/zHR1ZOArUro.

Abstract OBJECTIVE: Parent vessel sacrifice is a useful treatment strategy for fusiform intracranial aneurysms. Originally performed using the detachable silicone balloon, endovascular arterial occlusion is currently achieved using coils, a process which can be limited by coil mass migration. METHODS: We demonstrate the use of the Amplatzer vascular plug as a fixed anchor within the target parent vessel to facilitate coil-mediated occlusion, especially in vascular segments not encased by a bony canal. The technique was used successfully in two patients: a 90-year-old woman presenting with IIIrd and VIth cranial nerve palsy from a fusiform left cavernous internal carotid aneurysm and a 44-year-old man with distal thromboemboli from a fusiform dissecting-type right vertebral artery involving the origin of the posterior inferior cerebellar artery. RESULTS: Both patients were treated successfully with proximal parent vessel occlusion using coils after deployment of an Amplatzer vascular plug proximal to the target lesion. With the Amplatzer device acting as a fixed anchor in the parent vessel, coils were deployed proximally in a compact configuration. After deployment of the vascular plugs and coils, hermetic occlusion of the parent vessel was documented angiographically. CONCLUSION: The Amplatzer vascular plug can facilitate coil occlusion of large cervical vessels by acting as a focal coil and embolic material immobilizer, which can prevent coil mass migration and lead to improved packing density.

Every chromosome needs a centromere for proper segregation during cell division. Centromeric chromatin wraps around histones, providing an anchor for kinetochore proteins and spindle attachment. It is clear why cells need centromeres, but how they form and what they look like is less so. Recent reports extend our understanding of chaperones involved in centromere formation. And other accounts of half-sized, right-handed nucleosomes have created an unexpected twist.

Abstract OBJECTIVE: A patient with an anterior communicating artery aneurysm was treated by use of endovascular coiling, and a Guglielmi detachable coil (Boston Scientific/Target, Fremont, CA) fractured distal to its connection to the delivering catheter. The unraveled coil floated out from the aneurysm to extend into the bifurcation of the left middle cerebral artery. We describe the microsurgical procedure used to retrieve the coil after an endovascular approach failed. METHODS: The left anterior cerebral artery was punctured just below the aneurysm neck, and a titanium microhook was introduced to anchor the coil and pull it out. Slight traction was exerted before sectioning the coil to avoid protrusion of the stump into the parent vessel. RESULTS: The unraveled coil was removed in totality without permanent morbidity. CONCLUSION: This report describes the case of a rare complication of coil embolization treated with a minimal transarterial coil hooking procedure.

During meiotic prophase I of the fission yeast Schizosaccharomyces pombe, oscillatory nuclear movement occurs. This promotes homologous chromosome pairing and recombination and involves cortical dynein, which plays a pivotal role by generating a pulling force with the help of an unknown dynein anchor. We show that Mcp5, the homologue of the budding yeast dynein anchor Num1, may be this putative dynein anchor. mcp5+ is predominantly expressed during meiotic prophase, and GFP-Mcp5 localizes at the cell cortex. Moreover, the mcp5Δ strain lacks the oscillatory nuclear movement. Accordingly, homologous pairing and recombination rates of the mcp5Δ strain are significantly reduced. Furthermore, the cortical localization of dynein heavy chain 1 appears to be reduced in mcp5Δ cells. Finally, the full function of Mcp5 requires its coiled-coil and pleckstrin homology (PH) domains. Our results suggest that Mcp5 localizes at the cell cortex through its PH domain and functions as a dynein anchor, thereby facilitating nuclear oscillation.

Crossing the neck of large complex intracranial aneurysms for the purposes of stent deployment can be challenging using standard over the wire techniques. We describe a novel yet simple technique for straightening out the loop formed within a large intracranial aneurysm, which is often required in order to cross the aneurysm neck into the distal branch. Both the microcatheter and microwire are initially introduced into the distal vasculature, followed by withdrawal of the microwire to a point parallel to the distal exiting branch. The microcatheter and microwire are then gently withdrawn and a series of maneuvers to gradually reduce the loop is performed, obviating the need for distal purchase in the form of a stent, balloon, or coil, which have previously been described to maintain distal purchase.

Cortically anchored dynein orients the spindle through interactions with astral microtubules. In budding yeast, dynein is offloaded to Num1 receptors from microtubule plus ends. Rather than walking toward minus ends, dynein remains associated with plus ends due in part to its association with Pac1/LIS1, an inhibitor of dynein motility. The mechanism by which dynein is switched from “off” at the plus ends to “on” at the cell cortex remains unknown. Here, we show that overexpression of the coiled-coil domain of Num1 specifically depletes dynein–dynactin–Pac1/LIS1 complexes from microtubule plus ends and reduces dynein-Pac1/LIS1 colocalization. Depletion of dynein from plus ends requires its microtubule-binding domain, suggesting that motility is required. An enhanced Pac1/LIS1 affinity mutant of dynein or overexpression of Pac1/LIS1 rescues dynein plus end depletion. Live-cell imaging reveals minus end–directed dynein–dynactin motility along microtubules upon overexpression of the coiled-coil domain of Num1, an event that is not observed in wild-type cells. Our findings indicate that dynein activity is directly switched “on” by Num1, which induces Pac1/LIS1 removal.

Myosin VI is a pointed-end–directed actin motor that is thought to function as both a transporter of cargoes and an anchor, capable of binding cellular components to actin for long periods. Dimerization via a predicted coiled coil was hypothesized to regulate activity and motor properties. However, the importance of the coiled-coil sequence has not been tested in vivo. We used myosin VI's well-defined role in actin stabilization during Drosophila spermatid individualization to test the importance in vivo of the predicted coiled coil. If myosin VI functions as a dimer, a forced dimer should fully rescue myosin VI loss of function defects, including actin stabilization, actin cone movement, and cytoplasmic exclusion by the cones. Conversely, a molecule lacking the coiled coil should not rescue at all. Surprisingly, neither prediction was correct, because each rescued partially and the molecule lacking the coiled coil functioned better than the forced dimer. In extracts, no cross-linking into higher molecular weight forms indicative of dimerization was observed. In addition, a sequence required for altering nucleotide kinetics to make myosin VI dimers processive is not required for myosin VI's actin stabilization function. We conclude that myosin VI does not need to dimerize via the predicted coiled coil to stabilize actin in vivo.

The mining industry is a major consumer of rock bolts in the United States. Due to the high humidity in the underground mining environment, the rock bolts corrode and loose their load bearing capacity which in turn reduces the life expectancy of the ground support and, thus, creates operational difficulties and number of safety concerns [1]. Research on rock anchor corrosion has not been adequately extensive in the past and the effects of several factors in the mine atmosphere and waters are not clearly understood. One of the probable reasons for this lack of research may be attributed to the time required for gathering meaningful data that makes the study of corrosion quite challenging. In this particular work underground water samples from different mines in the Illinois coal basin were collected and the major chemical content was analyzed and used for the laboratory testing. The corrosion performance of the different commercial rock anchors was investigated by techniques such as laboratory immersion tests in five different corrosion chambers, and potentiodynamic polarization tests in simulated ground waters based on the Illinois coal basin. The experiments were conducted with simulate underground mining conditions (corrosive). The tensile strengths were measured for the selected rock anchors taken every 3 months from the salt spray corrosion chambers maintained at different pH values and temperatures. The corrosion potential (Ecorr), corrosion current (Icorr) and the corresponding corrosion rates (CR) of the selected commercial rock bolts: #5, #6, #6 epoxy coated and #7 forged head rebar steels, #6 and #7 threaded head rebar steels were measured at the solution pH values of 5 and 8 at room temperature. The open circuit potential (OCP) values of the different rock anchors were recorded in 3 selected underground coal mines (A, B & C) in the Illinois coal basin and the data compared with the laboratory electrochemical tests for analyzing the life of the rock anchors installed in the mines with respect to corrosion potential and corrosion current measured. The results of this research were statistically validated. This research will have direct consequence to the rock related safety. The results of this research indicate that certain corrosive conditions are commonly found in mines but uniform corrosion (around 0.01-0.03mm loss per year across the diameter) is generally not considered a serious issue. From this study, longer term research for long-term excavation support is recommended that could quantify the problem depending on the rock anchor used and specific strata conditions.

Rock anchors are used extensively in coal mines in the United States and around the world. The conditions in many of these coal mines are conducive towards the corrosion of rock anchors. Despite this, very little research has been performed to analyze corrosion and its effects on rock anchors in US coal mines. The specific aim of this thesis is to analyze typical Illinois Coal Basin (ICB) mine parameters and their effects on corrosion. A well understood relationship between these parameters and corrosion would be useful in locating highly corrosive areas and mitigating risks associated with corrosion. To study ICB mine parameters and their effects on corrosion, three general experiment types were carried out: in situ rock anchor analysis, simulated mine environment testing and analysis, and electrochemical testing and analysis. For in situ rock anchor analysis, open circuit potential (OCP) of rock anchors in coal mines with various conditions were measured. The OCP values can be used to predict whether or not corrosion of the rock anchors has initiated, and to study relationships between mine parameters and corrosion. The readings were also used to assess the validity of experimental setups by comparing experimental OCP values to in situ mine OCP values. The OCP readings obtained were found to vary by locations within the mines indicating corrosion conditions can vary relative to location. No clear trends were found between the OCP values and moisture or rock anchor age likely indicating numerous other factors were affecting the OCP values. These other significant factors will need to be determined and measured in addition to moisture and age in order to develop clear relationships between mine parameters and OCP values. Overall, the experimental OCP values found were slightly more negative than the in situ OCP values. This may have been due to the fact that the corrosion tanks exposed the rock anchors to more moisture. It is also a possible indication that mine rock anchors were not yet significantly corroding. For simulated environments, three tanks were filled with solution made by adding chloride ions, sulfate ions, and iron ions. The concentrations were based on water samples from mines and were the same for each tank. The temperatures of each tank were set at 30°C or 50°C, and the pH levels were set at 5.5 or 9.The tanks were then loaded with thirteen different types of rock anchors. The solution compositions were monitored over time, and the rock anchors were removed at specified intervals and tested to tensile destruction. The decreasing ultimate strengths of anchors were assumed to be related to the corrosion rate. This relationship was used to study the corrosion rates of multiple rock anchor types in varying conditions. Results seemed to indicate higher temperatures caused the highest corrosion rates. Basic pH levels caused a less significant increase in corrosion. With respect to reduced visible surface corrosion, epoxy coatings were the most effective followed by the proprietary coating, and then the galvanized coating. All bolts, cable anchors, and friction bolts with no coating had significant visible corrosion relative to rock anchors with protective coatings. Cable bolts with no coating and friction bolts seemed to have had the largest decrease in strength, and this is hypothesized to be a result of having larger exposed surface areas than other rock anchor types. For electrochemical testing and analysis, potentiodynamic polarization tests were used to estimate the corrosion potential (Ecorr) and corrosion current (Icorr) of rock anchor metals in simulated mine environments. Ecorr can be used as an indication of the conditions necessary for the initiation of corrosion, and Icorr can be used to determine the rate of corrosion. The effects of pyritic sulfur from coal samples in solution, pH of solution, temperature, and the bolt grade on Ecorr and Icorr values were analyzed. No significant trends were observed between electrochemical properties and pyritic sulfur concentrations. pH, temperature, and bolt grade were also parameters that were analyzed, and of these, only temperature had a significant effect on electrochemical properties. The penetration rate increased significantly with respect to increasing temperatures. All corrosion rates in the simulated mine water were considered low according to the standard specifying corrosion rates and characteristics that was used. This research has shown mine corrosion parameters are consistent in localized areas. The results, however show additional parameters other than age and moisture must be accounted for in order to accurately predict the risk of corrosion in a given mine. Simulated mine testing results showed that corrosion prevention coatings are effective in reducing corrosion in the conditions tested. Electrochemical test showed corrosion rates were all low in the mine solutions tested. Temperature had the most significant effect on corrosion rates in both the simulated mine tests and electrochemical tests. The electrochemical tests also showed that increased temperature can only simulate increased corrosion periods up to the point that other reaction factors limit the reaction rate independent of temperature. To fully understand corrosion risks in ICB mines, additional parameters and experimental methods should be considered in order to increase the understanding of relationship between ICB mine parameters and corrosion.

The development of recombinant proteins for therapeutic applications has revolutionized the pharmaceutical industry. In particular, monoclonal antibodies are the safest class of all therapeutic molecules and account for the majority of recombinant proteins currently undergoing clinical trials. A variety of technologies exist to engineer antibodies with a desired binding specificity and affinity, both of which are a prerequisite for therapeutic applications. This dissertation describes the implementation of a novel combinatorial library screening technology for the discovery and engineering of antibodies with unique binding properties. Combinatorial library screening technologies are used for the in vitro isolation of antibodies from large ensembles of proteins (libraries) typically produced by microorganisms using molecular biology techniques. Our lab has developed a powerful antibody discovery technology that relies on E. coli display by anchored periplasmic expression, otherwise known as APEx. First, I compared the effects of using combinatorial libraries comprising either smaller, monovalent single-chain antibody fragments (scFv), or the much larger, bifunctional full-length IgG antibodies. These technologies were used to isolate a small panel of antigen specific antibodies from the same library of antibody variable domains amplified from a mouse immunized with the Protective Antigen (PA) component from Bacillus anthracis, the causative agent of anthrax. Overall, IgG display resulted in the isolation of a broader panel of variable domain sequences. Most of these variable domains exhibited substantially reduced affinity when expressed as scFvs, which is consistent with the finding that none of these could be isolated from the equivalent scFv library. These results indicate that the antibody format used during in vitro selection affects which antibody variable domains will be discovered. Second, I developed several modifications of the APEx methodology to allow for more efficient recovery of antibodies with desired properties. Specifically, the system was reengineered to simultaneously account for antibody binding and expression levels in order to isolate the highest affinity antibodies with favorable expression characteristics. Third, the new approach, coupled with optimized fluorescence activated cell sorting (FACS) settings, was used to increase the affinity of an antibody by 35-fold resulting in a K[subscript D] of 100 pM. It was demonstrated that genetic transfer of this high affinity antibody specific for the V antigen of Yersinia pestis, the etiologic agent of the plague, conferred increased protection against intranasal challenge with a 363 LD₅₀ of Y. pestis in mice.

Deploying coils accurately in high-flow vessels can be challenging. Particularly with larger vessels, obtaining the stability to prevent downstream coil migration is of paramount importance. This is particularly true in the embolization of pulmonary arteriovenous malformations, in which distal coil migration to the systemic circulation can have disastrous consequences. Although detachable coils/balloons, hydrocoils, and plugs mitigate some of this risk, these devices are costly and not always readily available. Furthermore, there are times when a large plug may not be deliverable to the intended target, necessitating use of coils instead. This chapter describes two separate techniques to secure coils at their site of deployment—the anchor technique and the scaffold technique.

Lo iuris utriusque doctor Paolo da Castro (1360/62-1441), nella sua lunga ed onorata carriera accademica, lesse soltanto il gius civile. Il vasto – e ancora non sufficientemente esplorato – campo dei suoi consilia mostra però una profonda conoscenza anche del diritto canonico, fatto di cui anche il pubblico dei richiedenti dovette esser consapevole, vista la fiducia con cui sollecitò al giurista responsi in materia non soltanto civilistica. Partendo, perciò, da alcuni consilia che affrontano tematiche di attinenza canonistica (specialmente quando la competenza dei canoni entrava in concorrenza col diritto civile, come nel caso emblematico dell’usura cui finirono per connettersi le svariate questioni implicanti i mai pacificati rapporti istituzionali con le comunità ebraiche residenti nelle città italiane), si sono confrontate le opinioni espresse dal giurista con le posizioni che egli tiene nei passi corrispondenti delle lecturae accademiche e con quelle del suo maestro Baldo degli Ubaldi e di altri autori vicini, per tempo o per altre affinità (e.g. Bartolo, Lorenzo Ridolfi, Oldrado, Antonio Roselli, Giovanni da Imola), tentando di ricostruire la linea di pensiero di Paolo da Castro nella materia affrontata e la sua incidenza sulla communis opinio posteriore. Una dipendenza di Paolo da Castro da alcune teorie economiche e morali risalenti a Pietro di Giovanni Olivi (che aveva insegnato per qualche anno alla scuola teologica di Santa Croce a Firenze) è stata ipotizzata a partire da alcune possibili coincidenze favorite dal lungo soggiorno fiorentino del giurista. Queste avrebbero influenzato il pensiero di Paolo indirizzandolo verso posizioni etiche severissime, anche nei confronti di quella Chiesa di cui il giurista fu sempre un devoto, ma non inerte, seguace. Il panorama che si è venuto delineando durante il percorso d’indagine, perciò, non solo – secondo l’A. – mostrerebbe scenarî forse inattesi nel quadro giurisprudenziale relativo alle tematiche trattate e al pensiero di Paolo da Castro, specialmente nel suo formarsi; ma, soprattutto, consentirebbe di giustificare (e dunque elidere), su basi squisitamente tecniche ma anche intellettuali, le discrasie presenti in Paolo, non meno che in molti altri giuristi dei secoli tra Trecento e Cinquecento, tra l’opinio espressa come consulente e le interpretazioni sostenute leggendo dalla cattedra universitaria.

This chapter provides historical context for the book and anchors the text in place. Drawing on archival data collected form Kentucky and Alabama-based archives and oral history data collected from African Americans in the sample population, Brown describes the conditions under which the coal mining industry emerged in eastern Kentucky at the turn of the twentieth century. She also describes the economic and social conditions of black life in post-Reconstruction Alabama. Through this historical analysis, Brown reveals the antecedents of the mass migration of African Americans from the Alabama black belt into the coalfields of eastern Kentucky. Moving beyond the individual level push-pull framework of mass migration analysis, this chapter focuses on the role of corporations and fin de siècle northern industrialists in initiating calculated mass migration streams to meet their demand for labor.

By the late first century BC, most of north-west Europe had been incorporated into the Roman Empire or had fallen under its shadow. This has profoundly affected how the late Iron Age is perceived and studied. Being able to view peoples and places through written sources and coin inscriptions means that the archaeology of the period is often approached very differently to those discussed in previous chapters, with greater emphasis on historical events and causality. The chronology encourages this. Late La Tène sites on the Continent can now be dated to within a generation or so, anchored by a growing number of dendrochronological fixed points (Kaenel 2006; Durost and Lambert 2007), although similar precision is rarely attainable in northern Europe or in Ireland and northern Britain, which rely largely on radiocarbon dating. The prevailing narrative for the late Iron Age in central Europe, Gaul, and southern Britain—essentially the areas that later became part of the Roman empire—is one of increasing hierarchy, social complexity, political centralization, urbanization, and economic development. These changes are seen as bound up with increasing contact with the Mediterranean world, leading up to the Roman conquests of the first centuries BC and AD. This is contrasted with the situation in northern Britain, Ireland, and ‘Germanic’ northern Europe, which are assumed to have been more tradition-bound and resistant to change. As we shall see, recent excavations do not necessarily contradict this narrative, but they do suggest that the picture is far more complex. Not all developments can be fitted into the story of growing social complexity, whilst to assume that Roman expansion was the most important factor at work at this period is to see events through the eyes of Classical writers (Bradley 2007). It is important to understand late Iron Age societies in their own terms, rather than just as precursors to provincial Roman societies. Many influential approaches to the period—from core–periphery models to the current emphasis on the agency of client rulers (Creighton 2000)—suffer from teleology as a result of having been constructed with half an eye to explaining the pattern of Roman expansion.

Endovascular stents in the last decade have been extensively used in intracranial aneurysm (IA) management. Stenting procedure is normally performed with the placement of spring coils inside the aneurysm, where stent will serve as a mechanical scaffold to help anchor the packed coils. Although coiling holds relatively lower morbidity and mortality rate than traditional treatment, its applications to wide-necked IAs, IAs with large fusiform shapes, and thin-walled IAs are still problematic due to the difficulty of securing the coils in the first two scenarios and the vascular susceptibility to coil damage in the last situation. Recent flow diverter concept however offers a potential alternative to address these challenging cases with only stent (flow diverter) being implanted. A flow diverter stent usually has relatively high metal surface coverage rate (∼80%) so that it can significantly divert blood flow from going inside the aneurysm, causing the decreased flow in IA and subsequently the thrombogenic cascade in favor of occluding the lesion. Meanwhile, a new flow conduit across IA orifice is expected to form based on endothelial cell re-pavement on the inner surface of the stent. It is thus of academic and clinical importance to further examine the mechanisms involved with flow diverter to better understand the procedure and improve the treatment outcome. Since the straightening of vessel by stent and incomplete apposition between stent filaments and arterial wall could both induce complications, current study applies a developed finite element method (FEM) workflow to evaluate the conformity of a CoCr alloy flow diverter (Pipeline™ Embolization Device as PED by ev3, MN, USA) to patient specific IA geometries.

A production common rail type injector has been investigated via numerical simulation and experimentation. The functioning principle of the injector has been carefully analysed so as to obtain a mathematical model of the device. A zero-dimensional approach has been used for modelling the injector, thus considering the variables as function of time only. The analysis of the hydraulic part of the injector resulted in the definition of an equivalent hydraulic scheme, on which basis both the equations of continuity in chambers and flow through nozzles were written. The moving mechanical components of the injector, such as needle, pressure rod and control valve have been modelled using the mass-spring-damper scheme, thus obtaining the equation governing their motion. An electromagnetic model of the control valve solenoid has also been realized, in order to work out the attraction force on the anchor, generated by the electric current when flowing into its coil. The model obtained has been implemented using the Matlab® toolbox Simulink® and solved by means of the NDF (Numerical Differentiation Formulas) implicit scheme of the second order accuracy, suitable for problems with high level of stiffness. The experimental investigation on the common-rail injection system was performed on a test bench at some standard test conditions. Electric current flowing through the injector coil, oil pressure at the injector inlet, injection rate, needle lift and control valve lift were gauged and recorded during several injection phases. The mean reflux-flow rate and the mean quantity of fuel injected per stroke were also measured. Temperature and pressure of the feeding oil, as well as pressure in the rail were continuously controlled during the experimental test. The numerical and experimental results were compared. The model was then used to investigate the effect of control volume feeding and discharge holes and of their inlet fillet, as well as the effect of the control volume capacity, on the injector performance.

This paper briefly sets out the requirements for additional steam capacity at Anchor Products dairy plant at Te Awamutu in New Zealand and the reasons for choosing to use a relocated Turbo Power & Marine Twin Pac with a new waste heat recovery boiler together with an existing coal fired boiler to meet this demand. The paper then discusses the decision to replace the gas turbine and generator controls in their entirety, their integration with the controls for the new and existing boilers, and the architecture adopted for the total system. The philosophy of the control of the plant is then developed which leads to detailed discussion of the implementation of various modes of control of the plant, including, cogeneration control, co-ordinated control peaking control and compensate control and the methods of changing between the various modes of control. Finally, the paper includes a section on commissioning the plant.
