A model-based approach for analysis of intracellular resistance variations due to body posture on bioimpedance measurements (2013)

Bioimpedance spectroscopy is a known option for measuring body fluid volume. However, it is prone to a variety of influence factors which prevent a wider use. One of these influencing factors is the body posture. It could be shown that the average intracellular resistance percentage changes when the subject changes position from lying to standing. Most authors explain this phenomenon by fluid shifts. Another possible reason is the stray capacitance between the body and the ground, because if a certain fraction of the injected current follows other paths than between the potential electrodes, the result will be wrong. This paper analyses the influence of different body postures on the measured intracellular resistance and the posture depending capacity. For this purpose, FEM simulations are used. Subsequently, an electrical equivalent model with capacitances was developed. With this model, it is possible to correct the measured impedance and to neglect the influence of the stray capacitance.
Tumor-associated tissue eosinophilia in human esophageal squamous cell carcinoma. (2006)

The possible function of tumor-associated eosinophils has not yet been elucidated, but these findings indicate the importance of TATE in the biological behavior of SCC of the esophagus.
DICER1 and FOXL2 mutations in ovarian sex cord–stromal tumours: a GINECO Group study (2015)

Our results suggest that, in contrast to FOXL2 mutations in A-GCT, DICER1 mutations in SLCT might be more useful for prognosis than for diagnosis. However, study of a larger cohort of patients is necessary to establish this. Identification of genetic alterations in SCST offers promising therapeutic options.
Clinical significance of delayed or slow graft function in kidney transplantation recipients (2021)

Background: With increasing total number of patients who receive expanded criteria donor kidneys, it is important to maintain the function of kidney grafts. Methods: Retrospective medical records of kidney transplantation (KT) recipients from 2010 to 2021 in three hospitals were reviewed and analyzed. Patients were divided into three groups according to the degree of kidney function recovery after KT. Delayed graft function (DGF), slow graft function (SGF), and immediate graft function (IGF) were defined as the need for dialysis, serum creatinine levels 2.0 mg/dL but no need for dialysis, and serum creatinine levels <2.0 mg/dL at 1 week after KT, respectively. Results: Among a total of 1,899 KT recipients, 73 DGF (3.8%) and 137 SGF (7.2%) were shown. DGF and SGF were developed more common in older recipient. Also, they tended to occur in cases of older donor age, male, deceased donor KT, longer dialysis duration, and longer cold and warm ischemia time. Interestingly, DGF and SGF tended to increase recently. In the logistic regression analysis, older donor age, deceased donor, recent transplantation (since 2014) remained independent risk factors for both DGF and SGF compared with IGF. The most common cause of DGF was acute T-cell-mediated rejection and most of which were recovered after treatments such as rituximab, immunoglobulin and plasma exchange. During an average of 5 years of follow-up periods, 94 cases of graft failure and 40 cases of death were developed. DGF and IGF elevated graft failure risk as 3.0 (95% confidence interval [CI], 4.4-13.3; P=0.004) and 1.0 (95% CI, 0.53-1.9; P=0.983) times than IGF, respectively. There were no significant differences in mortality among three groups. Conclusions: In this multicenter retrospective analysis, we found increasing tendency of DGF in KT recipients. Different from SGF, DGF showed worse graft outcomes than IGF although they shared several risk factors. Further clinical dissection should be warranted to improve graft outcomes because DGF seems to be more common in recent years.
Stress-released Si3N4 fabrication process for dispersion-engineered integrated silicon photonics (2020)

We develop a stress-released stoichiometric silicon nitride (Si 3 N 4 ) fabrication process for dispersion-engineered integrated silicon photonics. To relax the high tensile stress of a thick Si 3 N 4 film grown by low-pressure chemical vapor deposition (LPCVD) process, we grow the film in two steps and introduce a conventional dense stress-release pattern onto a ∼400nm-thick Si 3 N 4 film in between the two steps. Our pattern helps minimize crack formation by releasing the stress of the film along high-symmetry periodic modulation directions and helps stop cracks from propagating. We demonstrate a nearly crack-free ∼830nm-thick Si 3 N 4 film on a 4” silicon wafer. Our Si 3 N 4 photonic platform enables dispersion-engineered, waveguide-coupled microring and microdisk resonators, with cavity sizes of up to a millimeter. Specifically, our 115µm-radius microring exhibits an intrinsic quality (Q)-factor of ∼2.0×10 6 for the TM 00 mode and our 575µm-radius microdisk demonstrates an intrinsic Q of ∼4.0×10 6 for TM modes in 1550nm wavelengths.
Synthesis of Antimitotic Thioglycosides: In Vitro and in Vivo Evaluation of Their Anticancer Activity (2011)

The synthesis and biological activity of oleylN-acetyl-α- and β-d-glucosaminides (1 and 2, respectively) and their thioglycosyl analogues (3 and 4, respectively) are reported. The compounds exhibited antimitotic activity on rat glioma (C6) and human lung carcinoma (A549) cell cultures in the micromolar range. Analysis of cell extracts using ultra performance liquid chromatography-mass spectrometry showed that the synthetic glycosides produce alterations in glycosphingolipid metabolism, with variable effect on the level of glucosylceramide depending on the configuration of the antimitotic used. In vivo experiments in nude mice bearing an implanted C6 glioma showed that the α-thioglycoside 3 reduced tumor volume, while the O-glycosyl derivative was inactive, highlighting the importance of using enzyme resistant glycosides.
In vivo cellular delivery of siRNA. (2010)

Current in vivo approaches for the delivery of siRNAs have been hindered by inefficient targeting to cells and by the triggering of immune responses. The cellular delivery of siRNA by immunoprivileged cells avoids the immune response, because the siRNA is delivered from one cell interior to another via gap junctions, thereby avoiding the extracellular compartment. Human mesenchymal stem cells (hMSCs) can be delivered focally or systemically, and have also exhibited the ability to migrate to targeted tissue in vivo. These features suggest the potential use of hMSCs as a cellular delivery system for siRNA. This feature review discusses the role of gap junctions to facilitate the transfer of siRNA directly to target cells, thus avoiding the disadvantages involved with approaches that are dependent on the extracellular space for siRNA delivery.
Ground and flight deck alternatives for terminal merging, sequencing, and spacing for arrivals (2007)

Aircraft approach the terminal area on different arrival paths, merge and ultimately arrive at capacity-constrained runways on the ground. Upon entering the terminal area, air traffic control manually controls the aircraft in order to merge and sequence arrivals on different paths, and establish longitudinal spacing between aircraft. These operations are termed merging, sequencing, and spacing operations. New technologies available in air traffic control facilities and in the flight deck create the possibility of improving on the manual operations used today. Several alternatives are currently in operational trials. Unclear is what alternative will prove to be most desirable for implementation. This paper seeks to enumerate some alternatives, and their characteristics, and establishes a framework for assessment.
Das Smartphone als universelles Diagnosegerät (2013)

Die Fehlerdiagnose stellt eine Disziplin dar, die heute fast ausschlieslich Fachkraften vorbehalten ist. Kaum ein Anwender kennt das detaillierte Innenleben eines automatisierten Systems und die zugehorigen Diagnoseverfahren. Die Folge ist, dass Systeme mit leicht behebbaren Defekten entsorgt werden oder ein aufwendiger Wartungsprozess mit Anrufen bei diversen Service-Hotlines in Gang gesetzt werden muss. In diesem Beitrag wird ein Diagnosekonzept vorgestellt, welches sich ohne explizites Diagnosefachwissen anwenden lasst. Zentraler Bestandteil des Konzepts ist ein Smartphone, das mit einer Diagnoseanwendung ausgestattet wird und damit als mobiles Diagnosegerat dient. Ein benutzerfreundliches Bedienkonzept und die Anbindung an eine zentrale Wissensbasis ermoglichen eine anwendergerechte Diagnose. Zudem deckt das beschriebene Konzept die weitergehenden Schritte der Fehlerbehebung mit Hilfe interaktiver Assistenzfunktionen ab, sodass das Diagnosegerat auch hierbei eine grostmogliche Unterstutzung bietet.
Elastic properties of NiTi (1991)

The authors present measurements of the elastic constants on a single crystal of the shape-memory alloy NiTi in a wide temperature range. Step-like anomalies and hysteresis are detected at the austenitic-martensitic phase transition which provide evidence for the strain-order parameter coupling in the pre-martensitic phases. The results are discussed in the framework of existing Landau theory models.
Progress toward the synthesis of the bicyclo (6.3.0) framework using TMM diyls (2006)

The ability of a vinylcyclopropyl substituted TMM diradical (e.g. 1) to transform to the bicyclo (6.3.0) framework is not restricted to cis cyclopropanes. Trans substituted systems work well, thereby significantly increasing the scope of the chemistry. Improved levels of regioselection toward the (6.3.0) system were observed. A mechanistic rationale for the increase is presented.

Decreased Bacterial Adhesion to Surface-Treated Titanium (2005)

Osteointegrative dental implants are widely used in implantology for their well-known excellent performance once implanted in the host. Remarkable bacterial colonization along the transgingival region may result in a progressive loss of adhesion at gum-implant interface and an increase of the bone area exposed to pathogens. This phenomenon may negatively effect the osteointegration process and cause, in the most severe cases, implant failure. The presence of bacteria at implant site affect the growth of new bone tissue and consequently, the achievement of a mechanically stable bone-implant interface, key parameters for a suitable implant osteointegration. In the present work, a novel surface treatment has been developed and optimized in order to convert the amorphous titanium oxide in a crystalline layer enriched in anatase capable of providing not only antibacterial properties but also of stimulating the precipitation of apatite when placed in simulated body fluid. The collected data have shown that the tested treatment results in a crystalline anatase-type titanium oxide layer able to provide a remarkable decrease in bacterial attachment without negatively effecting cell metabolic activity. In conclusion, the surface modification treatment analyzed in the present study might be an elegant way to reduce the risk of bacterial adhesion and increase the lifetime of the transgingival component in the osteointegrated dental implant.
The Friend Virus Genome: Partial Characterization of a Complete DNA Copy (1979)

SUMMARY A complementary DNA probe has been prepared from the Friend murine erythroleukaemia virus complex released by Friend cells (FV cDNAD-) and Friend cells induced to differentiate (FV cDNAD+). Molecular hybridization analysis shows that: (a) FV cDNAD+ is close to being a complete copy of the virus genome and the distribution of sequences is uniform with respect to their distribution in the Friend virus genome. (b) Hybridization of 70S RNA from the cloned helper virus to the total FVc DNAD+ probe demonstrates that a large proportion of the cDNA is specific to the transforming spleen focus forming virus. (c) Hybridization of the probe to normal and transformed cell DNA shows that there are about seven Friend virus related genes in normal DNA and almost twice this amount in transformed cell DNA. A significant minor proportion (20%) of the cDNA probe anneals only to virus related sequences in the transformed cell DNA. (d) An analysis of the kinetics of annealing of the cDNA to an excess template RNA shows that the minimum base sequence complexity of the Friend virus complex is 4 × 106. (e) An analysis of the cross hybridization between FV cDNAD+ and 60 to 70S RNA isolated from virus released by uninduced and induced cells shows that the genome of the induced and uninduced Friend virus is almost identical.
Atypical angiomatosis in polyarteritis nodosa (1986)

Biopsies from an area of livedo reticularis and adjacent to a leg ulcer in a woman with polyarteritis nodosa showed florid angioendothelial proliferation simulating angiosarcoma. This angioproliferative reaction has not been described previously in polyarteritis nodosa. Its microscopic differentiation from angiosarcoma is important.
On Differential Mobility Analyzer Resolution (1999)

The resolution of the differential mobility analyzer (DMA) is conveniently described as the ratio of the mobility at the peak of the column transfer function to the full width of the transfer function at 1/2 of its maximum value. The best resolution that can be achieved is that for nondiffusive particles, -_(nd) = β^(-1), where β is the flow rate ratio, β = (Q_a + Q_s)/(Q_(sh) + Q_e) . Brownian diffusion causes particles to deviate from the ideal electrophoretic migration trajectories, thereby reducing the resolution. The relative importance of electrophoretic migration to diffusion can be expressed as a function of the migration Peclét number, which can be expressed either in terms of mobilities, dimensions, and flow rates or as Pe_(m ig) = (qV/kT)f , where q is the charge on the particle, V is the applied voltage, and f is a geometry factor that accounts for nonuniformities in the electric field along the migration pathway. Expressed in this way, the performance of DMAs with different geometries, operating at different flow rates, are, in the absence of distortions in the flows and electric fields, shown to be nearly indistinguishable. Diffusion is shown to dominate at operating voltages below a critical value that is proportional to the square of the limiting resolution. Since the voltage range for DMA measurements is limited, the dynamic range decreases with increasing -_(nd) . Because of the changing size dependence of the mobility, this limitation is more pronounced for free-molecular aerosols than for larger particles.
Transcriptional and epigenetic regulation of T‐helper lineage specification (2014)

Combined with TCR stimuli, extracellular cytokine signals initiate the differentiation of naive CD4(+) T cells into specialized effector T-helper (Th) and regulatory T (Treg) cell subsets. The lineage specification and commitment process occurs through the combinatorial action of multiple transcription factors (TFs) and epigenetic mechanisms that drive lineage-specific gene expression programs. In this article, we review recent studies on the transcriptional and epigenetic regulation of distinct Th cell lineages. Moreover, we review current study linking immune disease-associated single-nucleotide polymorphisms with distal regulatory elements and their potential role in the disease etiology.
Transitioning Plants to New Environments: Beneficial Applications of Soil Microbes (2012)

An important goal of ex situ conservation and conservation science is to reintroduce rare plants to nature. A crucial step, which often begins in the laboratory or greenhouse, is the preparation of propagules. Whether you are using in vitro (tissue culture) or seed germination techniques, a major hurdle in propagule production is overcoming issues with acclimatization. Generally speaking, acclimatization is the process of adapting propagules to new environments. The use of in vitro techniques is gaining popularity for some of the rarest plant species (Fay 1992), but the development of cuticles, stomata, and photosynthetic functions are maladapted to the soil environment when grown in this manner. Acclimatization aims to facilitate those transitions, but the process has been plagued with high mortality rates (Kapoor et al. 2008). These high rates of failure occur whether plant material is moved from culture containers to soil (Pospíšilová et al. 1999) or from greenhouse to field (Estrada-Luna et al. 2000).

Axially Symmetric Eddy Currents in a Spherical Conductor (1970)

The general theory for the vector potential produced by a sinusoidal current of finite cross section is developed and applied to a coil encircling two concentric, spherical shells of finite electrical conductivities and permeabilities. Linear, isotropic, and homogeneous media are assumed throughout the analysis. First, the Green's function solution is obtained, and then the principle of superposition is used to effect the desired result. A number of physically observable phenomena—such as the impedance, the power loss due to the presence of the conductors, and the time-averaged electromagnetic force on the conductors—are subsequently calculated from the vector potential. The treatment is sufficiently general to allow the solution of a number of difficult problems of electromagnetic induction, while each of the expressions obtained for the physically observable phenomena is in terms of an infinite sum that may be readily evaluated on a computer.
Abstract IA21: Colorectal cancer and the microbiota (2020)

Abstract Increasing scientific and clinical data support a role for the microbiota (the microorganisms associated with the human body) in influencing systemic and tumor microenvironment immunity, promoting tumor growth and spread, and altering the responsiveness and toxicity towards therapeutics. Herein, we discuss both human data from meta’omics analyses and data from mechanistic studies in cell culture and animal models that support that the microbiota influences colonic tumorigenesis.

Sichuan pepper attenuates H2O2-induced apoptosis via antioxidant activity and up-regulating heme oxygenase-1 gene expression in primary rat hepatocytes (2017)

Sichuan pepper, a well-known traditional Chinese spice, is popularly used in Chinese cuisine. In this study, the antioxidant activities of Sichuan pepper water extract (SP) were evaluated both chemically [in 2,2-diphenyl-1-(2,4,6-trinitrophenyl) hydrazyl (DPPH) assay] and biologically [in 2,2′-azobis-(2-amidinopropane) (AAPH)-induced haemolysis assay]. The protective effect of SP against H2O2-induced cytotoxicity in primary Sprague Dawley rat hepatocytes was investigated by using cell viability assay, nuclear staining, intracellular reactive oxygen species (ROS) measurement and flow cytometry. It was found to possess high total phenolic content as assessed by the Folin–Ciocalteu method. The antiapoptotic effect of SP may be mediated, in part, by significantly inhibiting intracellular ROS generation and depletion of the mitochondrial membrane potential. SP was also found to enhance the cellular antioxidant defense system through up-regulating heme oxygenase-1 expression. SP is an effective antioxidant that can be consumed regularly as a functional food for the prevention of oxidative stress-related liver diseases. Practical applications The present study demonstrated that Sichuan pepper water extract (SP) could enhance the cellular antioxidant ability in hepatocytes. SP is an effective antioxidant that can be consumed regularly as a functional food for the prevention of oxidative stress-related liver diseases.
