Threat implications of the Internet of Things (2013)

There are currently more objects connected to the Internet than there are people in the world. This gap will continue to grow, as more objects gain the ability to directly interface with the Internet or become physical representations of data accessible via Internet systems. This trend toward greater independent object interaction in the Internet is collectively described as the Internet of Things (IoT). As with previous global technology trends, such as widespread mobile adoption and datacentre consolidation, the changing operating environment associated with the Internet of Things represents considerable impact to the attack surface and threat environment of the Internet and Internet-connected systems. The increase in Internet-connected systems and the accompanying, non-linear increase in Internet attack surface can be represented by several tiers of increased surface complexity. Users, or groups of users, are linked to a non-linear number of connected entities, which in turn are linked to a non-linear number of indirectly connected, trackable entities. At each tier of this model, the increasing population, complexity, heterogeneity, interoperability, mobility, and distribution of entities represents an expanding attack surface, measurable by additional channels, methods, and data items. Further, this expansion will necessarily increase the field of security stakeholders and introduce new manageability challenges. This document provides a framework for measurement and analysis of the security implications inherent in an Internet that is dominated by non-user endpoints, content in the form of objects, and content that is generated by objects without direct user involvement.
High-Efficiency Transformation of Mammalian Cells by Plasmid DNA (1987)

We describe a simple calcium phosphate transfection protocol and neo marker vectors that achieve highly efficient transformation of mammalian cells. In this protocol, the calcium phosphate-DNA complex is formed gradually in the medium during incubation with cells and precipitates on the cells. The crucial factors for obtaining efficient transformation are the pH (6.95) of the buffer used for the calcium phosphate precipitation, the CO2 level (3%) during the incubation of the DNA with the cells, and the amount (20 to 30 micrograms) and the form (circular) of DNA. In sharp contrast to the results with circular DNA, linear DNA is almost inactive. Under these conditions, 50% of mouse L(A9) cells can be stably transformed with pcDneo, a simian virus 40-based neo (neomycin resistance) marker vector. The NIH3T3, C127, CV1, BHK, CHO, and HeLa cell lines were transformed at efficiencies of 10 to 50% with this vector and the neo marker-incorporated pcD vectors that were used for the construction and transduction of cDNA expression libraries as well as for the expression of cloned cDNA in mammalian cells.
Hypocalcemia: updates in diagnosis and management for primary care. (2012)

Family physicians play a crucial role in educating patients about the long-term management and complications of hypocalcemia. Currently, management is suboptimal and marked by fluctuations in serum calcium and a lack of approved parathyroid hormone replacement therapy for hypoparathyroidism.
Recent advances in the phencyclidine model of schizophrenia (1991)

These findings suggest that endogenous dysfunction of NMDA receptor-mediated neurotransmission might contribute to the pathogenesis of schizophrenia. The relative implications of the PCP and amphetamine models of schizophrenia are discussed in relationship to the diagnosis and etiology of schizophrenia.
[Molecular staging of testicular cancer using polymerase chain reaction of the testicular cancer-specific genes]. (1999)

Most testicular germ cell tumors have serological tumor markers such as alpha-fetoprotein (AFP) and human chorionic gonadotropin beta-subunit (beta-HCG). On the other hand, molecular staging of these tumors has not been well established compared to other urogenital malignancies like prostate cancer. Recently, melanoma antigen (MAGE) which is one of the tumor-associated antigens recognized by cytotoxic T lymphocytes (CTL) has been found to be present in a variety of malignant tumor types and normal testis. In addition, Wilms' tumor-associated gene WT1 has been found to be expressed in some testicular cancers. Thus, we examined the expression of these genes in testicular cancer tissues and peripheral blood of cancer-bearing patients using reverse transcription-polymerase chain reaction (RT-PCR). The expression of the MAGE1-3 genes was examined in 34 testicular germ cell tumors (24 seminomas and 10 nonseminomas). Of the seminomas and nonseminomas, 87.5% and 40% were positive for MAGE1, 91.7% and 60% for MAGE2, and 83.3% and 30% for MAGE3, respectively. The expression of the MAGE genes was not correlated with the tumor stage. The expression of the WT1 gene was quantified in 26 testicular germ cell tumors. WT1 was highly expressed in 5 of the 7 high stage cases, but in only 4 of the 19 low stage cases (p < 0.01). The mRNA of these genes could not be detected from the peripheral blood of patients with high stage tumors. These results suggest that MAGE genes may be useful tumor markers for molecular staging of testicular cancer, especially seminoma, and that the WT1 gene may be a tumor marker for high stage testicular germ cell tumors. However, these genes cannot yet be used for molecular staging of testicular germ cell tumors.
Prefusion F–specific antibodies determine the magnitude of RSV neutralizing activity in human sera (2015)

Respiratory syncytial virus (RSV) is estimated to claim more lives among infants <1 year old than any other single pathogen, except malaria, and poses a substantial global health burden. Viral entry is mediated by a type I fusion glycoprotein (F) that transitions from a metastable prefusion (pre-F) to a stable postfusion (post-F) trimer. A highly neutralization-sensitive epitope, antigenic site Ø, is found only on pre-F. We determined what fraction of neutralizing (NT) activity in human sera is dependent on antibodies specific for antigenic site Ø or other antigenic sites on F in healthy subjects from ages 7 to 93 years. Adsorption of individual sera with stabilized pre-F protein removed >90% of NT activity and depleted binding antibodies to both F conformations. In contrast, adsorption with post-F removed ~30% of NT activity, and binding antibodies to pre-F were retained. These findings were consistent across all age groups. Protein competition neutralization assays with pre-F mutants in which sites Ø or II were altered to knock out binding of antibodies to the corresponding sites showed that these sites accounted for ~35 and <10% of NT activity, respectively. Binding competition assays with monoclonal antibodies (mAbs) indicated that the amount of site Ø-specific antibodies correlated with NT activity, whereas the magnitude of binding competed by site II mAbs did not correlate with neutralization. Our results indicate that RSV NT activity in human sera is primarily derived from pre-F-specific antibodies, and therefore, inducing or boosting NT activity by vaccination will be facilitated by using pre-F antigens that preserve site Ø.
Don't stress your plants...you'll make them sick (2015)

Growers often push plants to maximise market prices, but sometimes things can go terribly wrong. Manipulating plants can often cause plant stress and expose weakened crops to disease infection. In this article, plant pathologist Dr Bill Jarvis explains some common plant stresses to avoid.
HER-2/neu gene amplification by fluorescence in situ hybridization allows risk-group assessment in node-negative breast cancer. (1999)

In a collective of 112 node-negative breast cancer patients, we compared the prognostic impact of HER-2/neu gene amplification (AMP) determined by fluorescence in situ hybridization (FISH) and HER-2/neu protein overexpression (EXP) measured by immunohistochemistry (IHC) with traditional prognostic factors (tumor size, grade, steroid hormone receptor status, menopausal status) and tumor invasion markers uPA (urokinase-type plasminogen activator) and its inhibitor PAI-1 determined by enzyme immunoassay (ELISA). Median follow-up in patients still alive at time of analysis was 7 years. Automated FISH and IHC were performed on parallel-cut formalin-fixed paraffin-embedded tissue sections. HER-2/neu AMP was detected by FISH in 31% and HER-2/neu EXP was measured by IHC in 41% of the cases. In 13% of the tumors, both AMP and EXP were found. FISH and IHC results were concordant in 56% of all analyzed cases. In univariate analysis, HER-2/neu AMP significantly predicted both disease-free (DFS) and overall survival (OS). HER-2/neu EXP was significant for OS, only. In multivariate analysis of all analyzed prognostic factors, HER-2/neu AMP was the only independent predictive factor for both DFS and OS. CART analysis revealed that HER-2/neu AMP together with the combination uPA/PAI-1 allowed optimal risk-group assessment after a 7-year median follow-up: patients with low levels of both uPA and PAI-1 and no HER-2/neu AMP had a significantly lower relapse rate (4.6%) than the remaining patients (32%). In conclusion, HER-2/neu gene AMP determined by FISH allowed a more accurate risk-group assessment than HER-2/neu protein EXP measured by IHC. Combining the HER-2/neu gene status measured by FISH with levels of tumor invasion markers uPA and PAI-1 improves clinically relevant risk-group assessment. In addition to its prognostic strength, the significant impact of HER-2/neu AMP on OS may reflect its ability to predict resistance to systemic therapy.

EMBR-seq provides an efficient and cost-effective approach to quantify global gene expression profiles from low input bacterial samples.
Dose-related protection of exercise bronchoconstriction by montelukast, a cysteinyl leukotriene–receptor antagonist, at the end of a once-daily dosing interval* (1997)

The dose-related protective effects of montelukast, a potent and selective cysteinyl leukotriene-receptor antagonist, against exercise-induced bronchoconstriction were investigated in a five-period, randomized, incomplete-block, crossover study with montelukast (0.4, 2, 10, 50 mg) and placebo. The study subjects were 27 nonsmoking, healthy stable patients with asthma (mean forced expiratory volume in 1 second [FEV1], 82.0% predicted) who demonstrated a > or = 20% decrease in FEV1 while beta-agonist was withheld for 6 hours before treadmill exercise. The standard exercise challenge was performed 20 to 24 hours, and again 32 to 36 hours, after the second of two once-daily doses. The effect of oral montelukast on exercise was measured by the area above the postexercise percentage decrease in FEV1 versus time curve from 0 to 60 minutes [AUC(0-60)], the maximal percentage decrease in FEV1 after exercise, and time after maximal decrease to recovery of FEV1 to within 5% of the preexercise baseline. Twenty to 24 hours after administration, montelukast caused dose-related protection, while providing similar protection against exercise-induced bronchoconstriction at the two highest doses. The AUC(0-60) values (mean +/- SD) were 637 +/- 898, 715 +/- 870, 988 +/- 1147, and 927 +/- 968 min. % for 50, 10, 2, and 0.4 mg montelukast, respectively, and 1193 +/- 1097 min. % for placebo (p = 0.003). No important clinical effect was present 36 hours after dosing. Montelukast was generally well tolerated at all dose levels. In conclusion, montelukast caused dose-related protection against exercise-induced bronchoconstriction at the end of a once-daily dosing interval. Protection against exercise-induced bronchoconstriction can be used to determine appropriate dose selection.
Regulation of 25-hydroxyvitamin D3-1α-hydroxylase and production of 1α,25-dihydroxyvitamin D3 by human dendritic cells (2003)

25-Hydroxyvitamin D3-1 alpha-hydroxylase (25(OH)D3-1 alpha-hydroxylase), the key enzyme of 1 alpha,25-dihydroxyvitamin D3 (1,25(OH)2D3) production, is expressed in monocyte-derived macrophages (MACs). Here we show for the first time constitutive expression of 25(OH)D3-1 alpha-hydroxylase in monocyte-derived dendritic cells (DCs), which was increased after stimulation with lipopolysaccharide (LPS). Accordingly, DCs showed low constitutive production of 1,25(OH)2D3, but activation by LPS increased 1,25(OH)2D3 synthesis. In addition, 25(OH)D3-1 alpha-hydroxylase expression was found in blood DCs but not in CD34+-derived DCs. Next we analyzed the functional consequences of these results. Addition of 1,25(OH)2D3 at concentrations comparable with those produced by DCs inhibited the allostimulatory potential of DCs during the early phase of DC differentiation. However, terminal differentiation decreased the responsiveness of DCs to 1,25(OH)2D3. In conclusion, DCs are able to produce 1,25(OH)2D3 especially following stimulation with LPS. Terminal maturation renders DCs unresponsive to the effects of 1,25(OH)2D3, but those cells are able to suppress the differentiation of their own precursor cells in a paracrine way through the production of 1,25(OH)2D3.
Oxides and nitrides as alternative plasmonic materials in the optical range (2011)

As alternatives to conventional metals, new plasmonic materials offer many advantages in the rapidly growing fields of plasmonics and metamaterials. These advantages include low intrinsic loss, semiconductor-based design, compatibility with standard nanofabrication processes, tunability, and others. Transparent conducting oxides such as Al:ZnO, Ga:ZnO and indium-tin-oxide (ITO) enable many high-performance metamaterial devices operating in the near-IR. Transition-metal nitrides such as TiN or ZrN can be substitutes for conventional metals in the visible frequencies. In this paper we provide the details of fabrication and characterization of these new materials and discuss their suitability for a number of metamaterial and plasmonic applications.
Virtual private networks: leveraging the Internet (1997)

Proponents say virtual private networks could be the wave of the networking future for one very important reason: VPNs transmit data via the Internet, rather than via expensive traditional private networks. Proponents are quick to mention the significant cost savings organizations can realize by using networks that employ the Internet backbone as a data pipeline rather than networks that rely on leased lines, frame-relay technology, and dialup connections for private WANs. However, as with many Internet technologies, potential VPN users are concerned about possible security, reliability, and performance problems. ln addition, a lack of open standards has created concerns about compatibility. The industry is working toward adoption of such standards, but it remains to be seen whether this will lend credibility to VPN technology.
Power Flow Control of a Single Distributed Generation Unit (2008)

This research addresses power flow control problem of a grid-connected inverter in distributed generation applications. A real and reactive power control solution is proposed on the basis of an existing voltage control strategy developed for island operations. The power control solution takes advantage of a newly designed system parameter identification method and a nonlinear feedforward algorithm, both of which are based on Newton-Raphson iteration method and implemented in real time. The proposed power control solution also performs grid-line current conditioning and yields harmonic free grid-line current. A phase locked loop based algorithm is developed as a part of the solution to handle possible harmonic distorted grid-line voltage and maintain harmonic free line current. The effectiveness of the proposed techniques is demonstrated by both simulation and experimental results.
Dekontamination menschlicher Spenderhornhäute während der Präparation und Konservierung (1996)

Endophthalmitis after penetrating keratoplasty is rare but more frequently observed than after other intraocular procedures. The main source may be a contaminated donor cornea. This survey reviews current concepts of donor globe decontamination and avoidance of infection during preservation. Basically, we suggest the use of a 3% PVP-Iodine solution for decontamination of donor globes. Using short-term preservation techniques, the tissue should be stored at ambient temperature after preparation of corneoscleral disc or before transplantation for a while to allow antibiotics to act against decontaminants. Tissue stored by organ culture should be kept in a sealed vial. Alternatively, the medium may be changed every 10 to 14 days under sterile conditions.
Tumour necrosis factor as a therapeutic target in rheumatoid arthritis and other chronic inflammatory diseases: the clinical experience with infliximab (REMICADE). (2001)

Therapeutic strategies that aim to neutralise the important pro-inflammatory cytokine tumour necrosis factor alpha (TNF alpha) have gained considerable prominence in the therapy of chronic inflammatory diseases, notably rheumatoid arthritis and Crohn's disease. This drug focus review will concentrate on the antitumour necrosis factor antibody infliximab (Remicade), which has been approved for the treatment of rheumatoid arthritis and Crohn's disease in both the US and Europe. In addition, infliximab is under investigation for several other indications, mainly inflammatory rheumatic diseases. Clinical trials have been persuasive that infliximab is both safe and effective, and it has been proven to be far superior to the conventional drug therapy in both rheumatoid arthritis and Crohn's disease. Remarkably, infliximab in combination with methotrexate controls both the inflammatory joint symptoms and the progression of joint damage, which renders it a very attractive therapeutic option in moderate to severe, therapy-resistant rheumatoid arthritis.
The Behavior of Lignin during Hydrolysis of Sweetgum Wood with Concentrated Hydrochloric Acid at Moderate Temperatures (1981)

Interferon-inducible protein 10 induction and inhibition of angiogenesis in vivo by the antitumor agent 5,6-dimethylxanthenone-4-acetic acid (DMXAA). (2001)

5,6-Dimethylxanthenone-4-acetic acid (DMXAA), a drug synthesized in this laboratory that halts tumor blood flow and induces tumor hemorrhagic necrosis in transplantable murine tumors, is known to induce the synthesis of antiangiogenic cytokines in vitro. We have measured the induction of mRNA for modulators of angiogenesis in vivo and investigated whether DMXAA may also have an additional antiangiogenic action through the production of these cytokines. The genes for IFN-alpha and for interferon-inducible protein 10 (IP-10) were strongly induced in both spleen and Colon 38 tumor tissue after DMXAA treatment, whereas that for IFN-gamma was induced in spleen but not in tumor. Expression of mRNA for IFN-beta and for the p35 or the p40 subunits of interleukin 12 was not observed in either tissue. Splenic IP-10 mRNA induction was not a result of IFN-gamma production induced with DMXAA because spleen tissue from DMXAA-treated mice that lacked functional IFN-gamma receptors expressed similar amounts of IP-10 mRNA as those from wild-type mice. A single i.p. injection of DMXAA (20 mg/kg) was sufficient to reduce fibroblast growth factor-induced endothelial cell invasion of Matrigel implants in athymic nude mice by nearly 100%. The inactive analogue 8-methylxanthenone-4-acetic acid did not up-regulate the genes for IP-10 or IFNs and did not inhibit endothelial cell invasion. Antibodies to IP-10 reversed the inhibition of DMXAA of endothelial cell invasion by 58%; antibodies to tumor necrosis factor-alpha, IFN-gamma, and IFN-alpha reversed inhibition by 7%, 5%, and 0%, respectively. The data support the hypothesis that DMXAA, in addition to antivascular effects mediated by tumor necrosis factor-alpha, may have an antiangiogenic effect mediated largely by the induction of IP-10.
A hierarchy preserving hierarchical compactor (1990)

This paper describes a one-dimensional compactor which simultaneously compacts the contents of all cells of a layout hierarchy without changing the hierarchy. The compactor performs both compaction and wire length minimization hierarchically using the power of the Simplex method for linear programs. Compaction of arrays, compaction of overlapping cells, and symmetry preserving compaction are also handled, since these are special cases of layout hierarchies. Using dedicated Simplex algorithms for compaction and wire length minimization, a globally optimum result is produced quickly and efficiently without the use of protection frames or domains and terminals. The compactor corrects design rule violations, preserves wire widths, and maintains terminal connections automatically. It does not yet introduce jogs in wires automatically. Results are provided for a few CMOS modules, including a ROM and an SRAM core.
Fi beropt ic M icrotransducer Pressure Technology: U rodynamic Implications (1993)

The FST 200 is a novel commercially available pressure measurement system that combines microtechnology and fiberoptics and is particularly well suited for invasive urodynamic studies. Pressure recording with this system is highly accurate and reproducible. The pressure curves obtained parallel those from standard water cystometry. Being small and portable, the system lends itself to invasive transurethral monitoring in the privacy of an examination room. Additionally, the 5F catheter size allows the performance of leak point pressures and pressure/flow voiding studies with minimal urethral stenting artifact often seen with larger catheters. The technical aspects of this system are presented. 0 1993 Wiley-Liss, Inc.
Detection and Determination of p-Coumaroylated Units in Lignins (1999)

The derivatization followed by reductive cleavage (DFRC) method cleaves alpha- and beta-ethers in lignins but leaves lignin gamma-esters intact. When applied to grasses, which contain p-coumarate esters on their lignins, esterified monolignol derivatives are released. Saturation of the p-coumarate double bond occurs during DFRC, so the released products are 4-acetoxycinnamyl 4-acetoxyphenylpropionates. Synthesis of the esters allowed determination of response factors for the released products. Maize and bamboo lignins released 221 and 38 micromol/g of p-coumarate-derived esters. The sinapyl ester was much more abundant than the coniferyl one. The bamboo and maize lignin S/G ratios in the conjugates were 12 and 38 times greater than those of the normal monomers released by DFRC, evidence of a strong selectivity for acylation of syringyl units. Of three possible biochemical mechanisms for incorporating p-coumarates into lignin, evidence is mounting that the process involves incorporation of preacylated monolignols into the normal lignification process.
A Rabbit Langendorff Heart Proarrhythmia Model: Predictive Value for Clinical Identification of Torsades de Pointes (2006)

A 30-fold margin between effects and EFTPC(max) is sufficiently stringent to provide confidence to proceed with a new chemical entity, without incurring the risk of eliminating potentially beneficial drugs. The model is particularly useful where compounds have small margins between the hERG IC(50) and predicted EFTPC(max). These data suggest this is a robust and reliable assay that can add value to an integrated QT/TdP risk assessment.
