The Pars Defect as a Pain Source (1995)

The finding of neural elements, including free nerve endings within the pars defect tissue, suggests that the pars defect may be a source of back pain in some patients with symptomatic spondylolysis.
Studies in the Mechanism of Sublate Removal by Solvent Sublation. Part I (1970)

Abstract Solvent sublation, a method related to ion flotation, was studied by sublating hexadecyltrimethylammonium bromide and Methyl Orange into 2-octanol. It was shown that if the aqueous solution was saturated with 2-octanol, removals of Methyl Orange were much slower than with unsaturated solutions, because the 2-octanol. tended to exclude collector from the bubble surface. The amount of Methyl Orange sublated was found to be different from that at liquid-liquid equilibrium, although the system reverted to the latter state if the sublation was discontinued and the solution was stirred. The organic phase retained any material passed into it and, other than the effects due to solubility, its presence had little influence on the processes occurring in the bulk of the aqueous solution. A detailed mechanism for sublate removal by solvent sublation is proposed.
Application of a simplified real‐frequency synthesis method to distributed‐element amplifier design (1991)

Abstract The simplified real‐frequency method is probably the best microwave circuit synthesis method available for the design of broadband amplifiers for electronic countermeasure (ECM) or communications applications. When applied to the design of interstage equalizers for microwave amplifiers, the procedure, contrary to classical synthesis techniques, utilizes only the measured scattering parameters of the 2‐port active device. The method thus directly includes device feedback effects, and neither an a priori choice of matching network topology nor an analytical form of the system transfer function is necessary. In the version described in this article, the optimization process is applied simultaneously to transducer power gain, input match (VSWR), and noise figure of a multistage amplifier. A procedure for directly extracting distributed transmission line elements for matching networks is briefly described. The program FREEL is then applied to the design of 3‐stage 2‐8‐GHz and 1.15‐1.5‐GHz MESFET amplifiers in which three topologies are compared: lumped element, cascaded transmission line, and transmission line and open circuited stubs.
Electronic tuning effects via π-linkers in tetrathiafulvalene-based dyes (2014)

Four new tetrathiafulvalene (TTF)-based dyes featured with a donor–bridge–acceptor (D–π–A) structure were synthesized and characterized. All of them undergo two reversible oxidations to form stable radical cation and dication species. The electronic interactions between the TTF donor and the cyanoacrylic acid acceptor through the different π-linkers have been demonstrated by the presence of a photo-induced intramolecular charge-transfer (ICT) absorption band in the visible region. A red shift of the ICT state can be finely tuned by the degree of aromaticity and extended conjugation of π-bridges. To some extent, the oxidation potentials of these dyes are affected by the nature of π-bridges. They have been applied in organic dye-sensitized solar cells, showing relatively low power conversion efficiencies of up to 0.87% due to substantial charge recombination losses.
An appraisal of sample preparation, analysis and some toxicological implications of ancient industrial metalliferous pollution (2017)

Metalliferous deposits are common worldwide. Some have been derived from activities following industrial revolutions in various countries, albeit at somewhat differing times. Others can trace their antiquity much further. This appraisal seeks to consider the associated activities of sample collection protocols and selected analytical procedures and considers results, in a broad-based manner, from diverse geographic areas of our planet which exhibit a clearly defined recent or ancient industrial heritage.
Dynamic combinatorial chemistry with hydrazones: libraries incorporating heterocyclic and steroidal motifs (2010)

We expand the possibilities in hydrazone based dynamic combinatorial chemistry with a series of new building blocks incorporating heterocyclic motifs. The synthetic procedure allows efficient access to building blocks with the general structure (MeO)(2)CH-Heterocycle-C(O)NHNH(2), originating from heterocycles with an amine and an ester functionality. The equilibrium distribution of macrocyclic N-acyl hydrazones formed upon deprotection of the building blocks with TFA in organic solvents is reported. The mixing behaviour of these heterocycle-based building blocks with our cholate-based building blocks is described, particularly the observation of kinetic intermediates that disappear following 'proof-reading'.

Performance Analysis of Optical Packet Switches with Reconfiguration Overhead (2011)

In optical packet switches, the overhead of reconfiguring a switch fabric is not negligible with respect to the packet transmission time and can adversely affect switch performance. The overhead increases the average waiting time of packets and worsens throughput performance. Therefore, scheduling packets requires additional considerations on the reconfiguration frequency. This work intends to analytically find the optimal reconfiguration frequency that minimizes the average waiting time of packets. It proposes an analytical model to facilitate our analysis on reconfiguration optimization for input-buffered optical packet switches with the reconfiguration overhead. The analytical model is based on a Markovian analysis and is used to study the effects of various network parameters on the average waiting time of packets. Of particular interest is the derivation of closed-form equations that quantify the effects of the reconfiguration frequency on the average waiting time of packets. Quantitative examples are given to show that properly balancing the reconfiguration frequency can significantly reduce the average waiting time of packets. In the case of heavy traffic, the basic round-robin scheduling scheme with the optimal reconfiguration frequency can achieve as much as 30% reduction in the average waiting time of packets, when compared with the basic round-robin scheduling scheme with a fixed reconfiguration frequency.
Evaluation of Nintendo Wii Balance Board as a Tool for Measuring Postural Stability After Sport-Related Concussion (2020)

Recent changes to postconcussion guidelines indicate that postural-stability assessment may augment traditional neurocognitive testing when making return-to-participation decisions. The Balance Error Scoring System (BESS) has been proposed as 1 measure of balance assessment. A new, freely available software program to accompany the Nintendo Wii Balance Board (WBB) system has recently been developed but has not been tested in concussed patients.
Thermal stresses around void in Through Silicon Via in 3D SiP (2014)

Thermal stresses around void in TSV (Through Silicon Via) structure in 3D SiP were discussed under the conditions of device operation and reflow process by using FEM (Finite Element Method). In case of the condition of device operation, equivalent stress around void inside Cu TSV was estimated at around 100 MPa. It showed the low possibility for low cycle fatigue of Cu TSV under device operation because that the stress was lower than yield stress of copper, 210MPa. Maximum principal stress of Si was estimated around 100 MPa. It was lower than bending stress of Si. In case of the condition of reflow process, the equivalent stress of TSV with void was higher than yield stress of Cu. However temperature elevation due to reflow process was once or twice during the process. It showed the low possibility for fracture by low cycle fatigue under reflow process. In case without void, maximum principal stress of Si was estimated around 400 MPa. It was almost similar to the bending strength of Si. Stress concentrations were occurred at parts of corner and interface of materials. It has possibility that singular stress field was formed at the parts, and we should discuss fracture induced by singular stress field.
SpaceFibre/SpaceWire-RT implementation experience and evolution trends (2014)

The paper considers experience of SpaceFibre/SpaceWireRT implementation and analysis. Overheads are estimated and gaps in the SpaceFibre draft for implementation are considered, its refinement is proposed. The problems in the Retry level are discussed. In case of repeating a frame the virtual channels characteristics (priorities, timeslots) are not fully followed; it could corrupt required QoS of the traffic. Another problem with the Retry level is shown in a case study of streaming data traffic. For such type of traffic late frames transmission could be not only useless but harmful for the target traffic. To deal with the problems a modification of Retry is proposed. Another open problem is in disconnection of a link at the Lane and Encoding levels when there is a need to change virtual channels (VC) logical numbers. When one needs to switch on or change a logical number of a single VC the link disconnection and restart is done. Thus data transfer would be stopped for all the VC of the link. It leads to considerable delays in tuning logical structuring of networks, excessive delays in virtual channel transfers when other VC in the same controller are retuned, excessive complication and resources in processor-less nodes implementations. To deal with the problem a modification of link flow control crediting is proposed.
A Water Soluble CoQ10 Formulation Improves Intracellular Distribution and Promotes Mitochondrial Respiration in Cultured Cells (2012)

The improved cellular energy metabolism related to increased CoQ(10) content represents a strong rationale for the clinical use of coenzyme Q(10) and highlights the biological effects of Qter®, that make it the eligible CoQ(10) formulation for the ubiquinone supplementation.
Calotropis procera, Apple of Sodom (2018)

ABSTRACT The desert plant, Calortopis procera , known also as the apple of Sodom, is an important but less known medicinal plant. This plant has many ethnic medicinal uses especially for skin-related symptoms in the countries of its origin: India, Africa, Saudi, Yemen, Lebanon, Israel, Jordan, Sudan, Iran, and Afghanistan. The plant is also known and used in traditional medicine in South and tropical America, due to its introduction and cultivation in that part of the world. Skin problems treated by the plant include: wounds, scabies, sores, external infections, swellings, rheumatic pains, leprosy, toothaches, eczema and even the treatment of paralyzed limbs. Other traditional uses include: asthma, cough, diarrhea, malaria, cancer, dysentery jaundice and many more. An insight into the scientific activity of C. procera derived extracts and compounds suggest that these extracts have antidiabetic, anticancer, anti-inflammatory and antibacterial activities. Moreover, a compound with high activity against cancer cell was developed from cardenolides present in C. procera root bark, presenting a significant prospect in the use of this plant for modern medicine. The purpose of this communication is to review the full extent of the ethnobotanical uses of the apple of Sodom, and to shed a light on this high-potential lesser-known desert medicinal plant.

Effects of insulin, insulin-like growth factor-II, and nerve growth factor on neurite formation and survival in cultured sympathetic and sensory neurons (1986)

Insulin and the insulin-like growth factors (IGFs) may directly affect the development of the nervous system. NGF, IGF-II, and insulin's effects on neurite formation and neuronal survival were studied in peripheral ganglion cell cultures from chick embryos. Neurite outgrowth was enhanced in a dose-dependent manner by insulin and IGF-II in sympathetic cell cultures. The half-maximally effective concentration, ED50, was about 0.4-0.6 nM for both polypeptides, and concentrations as low as 10 pM were active. However, in sensory neurons the ED50 for neurite outgrowth was about 30 nM for insulin and 0.1 nM for IGF-II, suggesting that these factors may have selective effects in different neuronal tissues. Neither serum nor the presence of non-neuronal cells was required for the response in sympathetic neurons. The specific anti-NGF antiserum inhibited the neurite outgrowth response to NGF but not to insulin nor IGF-II. Insulin and IGF-II additionally supported survival of sensory and sympathetic neurons; however, insulin was not as efficacious as NGF. The combination of high concentrations of NGF and insulin was no better than NGF alone in supporting sympathetic cell survival, or neurite outgrowth. This indicates that insulin acts on the same, or a subpopulation, of NGF-responsive neurons. These results support the hypothesis that insulin and its homologs belong to a broad family of neuritogenic polypeptides.
Co-culture of Adult Mesenchymal Stem Cells and Nucleus Pulposus Cells in Bilaminar Pellets for Intervertebral Disc Regeneration (2009)

Background: Our goal is to optimize stem cell-based tissue engineering strategies in the context of the intervertebral disc environment. We explored the benefits of co-culturing nucleus pulposus cells (NPC) and adult mesenchymal stem cells (MSC) using a novel spherical bilaminar pellet culture system where one cell type is enclosed in a sphere of the other cell type. Our 3D system provides a structure that exploits embryonic processes such as tissue induction and condensation. We observed a unique phenomenon: the budding of co-culture pellets and the formation of satellite pellets that separate from the main pellet. Methods: MSC and NPC co-culture pellets were formed with three different structural organizations. The first had random organization. The other two had bilaminar organization with either MSC inside and NPC outside or NPC inside and MSC outside. Results: By 14 days, all co-culture pellets exhibited budding and spontaneously generated satellite pellets. The satellite pellets were composed of both cell types and, surprisingly, all had the same bilaminar organization with MSC on the inside and NPC on the outside. This organization was independent of the structure of the main pellet that the satellites stemmed from. Conclusion: The main pellets generated satellite pellets that spontaneously organized into a bilaminar structure. This implies that structural organization occurs naturally in this cell culture system and may be inherently favorable for cell-based tissue engineering strategies. The occurrence of budding and the organization of satellite pellets may have important implications for the use of co-culture pellets in cell-based therapies for disc regeneration. Clinical Relevance: From a therapeutic point of view, the generation of satellite pellets may be a beneficial feature that would serve to spread donor cells throughout the host matrix and restore normal matrix composition in a sustainable way, ultimately renewing tissue function. © 2009 The Spine Arthroplasy Society.

Geografia da diálise peritoneal no Brasil: análise de uma coorte de 5.819 pacientes (BRAZPD) Geography of peritoneal dialysis in Brazil: analysis of a cohort of 5,819 patients (BRAZPD) (2010)

Introduction: Brazil is a continental country with great diversity of population, social and cultural. This factor may determine different demographic, clinical and outcome presented by patients with chronic kidney disease on peritoneal dialysis (PD). Objective: To evaluate the clinical characteristics and outcomes presented by PD patients in different regions of Brazil, analyzing a cohort of patients (BRAZPD) in the period 12/2004 to 10/2007. Patients and Methods: Data were collected monthly and patients were followed until the outcome (death, renal transplantation, renal function recovery, transfer to hemodialysis or loss of followup). Results: We evaluated 5.819 patients incident and prevalent. Most patients performed renal replacement therapy (RRT) in the Southeast, where the average follow up time was longer (12.3 months) and there is a higher percentage of elderly (36.4%). The prevalence of diabetes is higher in Southeast and South (38.1% and 37%, respectively). Most patients in the North region had previously hemodialysis (66.2%). The mortality was higher in the Northern region (30.1%), as well as failure of the technique (22.3%). Conclusion: The data shows different demographic, clinical, mortality and technique failure of PD reflecting the demographic and social peculiarities of Brazil. The geography of the DP in Brazil proves to be a mirror of the geography of Brazil. So health policies should take into account the characteristics of each region so we can improve patient survival and technique on peritoneal dialysis.
Axial dynamics in field-reversed theta pinches. I: Formation (1991)

Bias field scans are performed at various fill pressures in the FRX-C [Fusion Technol. 9, 13 (1986)] and FRX-C/LSM [Plasma Physics and Controlled Nuclear Fusion Research (IAEA, Vienna, 1989), Vol. II, p. 517] field-reversed theta pinches. These data show a systematic degradation of the confinement properties of field-reversed configurations whenever strong axial implosions occur during plasma formation. This limitation prevents access to the desired regime of large-size and long-lived field-reversed configurations. The cause of the confinement degradation must be due to some formation or gross stability problem. Here many studies are reported that attempt to correlate confinement degradation with some formation characteristic. These investigations remain inconclusive and suggest further stability studies presented in a companion paper.
A Four-Day Study Helps Home Building Move Indoors (1996)

By simulating Glaize Components' new wall panel production line, we sought to increase the capacity of this advanced CAD/CAM flexible manufacturing system. Developing the model was complicated by healthy industry skepticism, a short time window, and limited resources. By adhering strictly to a condensed, yet comprehensive project plan and using high quality animation, the project team overcame these barriers. Simulation results suggested that Glaize could increase production line capacity eight percent by resequencing, alternating between interior and exterior panels. Gaining confidence from the simulation results, Glaize tried alternating panels, and it worked. The change has yielded a seven to 10 percent increase in line capacity with minimal increases in capital and labor.
