Recognition by cytotoxic T lymphocytes of cells expressing fragments of the SV40 tumor antigen. (1983)

Recognition by cytotoxic T lymphocytes (CTL) of syngeneic cells transformed with simian virus 40 (SV40) was examined by using cells expressing known portions of the SV40 early region both as sensitizing cells for stimulation of CTL development and as targets for lysis by CTL. LMTK- cells transfected with a plasmid specifying a 33K amino-terminal fragment of the SV40 tumor (T) antigen served both to stimulate syngeneic CTL capable of lysing SV40 transformed cells and as target cells for CTL generated against syngeneic transformants. The same is true for cells infected with the adenovirus 2-SV40 hybrid viruses, Ad2+ND1 and Ad2+ND2, which produce proteins homologous with carboxy-terminal regions of the SV40 T antigen. These findings indicate that on cells transformed by SV40 virus, and expressing the entire T protein, determinants in both the amino- and carboxy-terminal regions of the molecule are exposed on the cell surface. Furthermore, determinants in both these regions are recognized independently in the polyclonal CTL response to SV40.
Upconversion luminescence and blackbody radiation in tetragonal YSZ co-doped with Tm<sup>3+</sup> and Yb<sup>3+</sup> (2015)

Lanthanide doped inorganic nanoparticles with upconversion luminescence are of utmost importance for biomedical applications, solid state lighting and photovoltaics. In this work we studied the downshifted luminescence, upconversion luminescence (UCL) and blackbody radiation of tetragonal yttrium stabilized zirconia co-doped with Tm(3+) and Yb(3+) single crystals and nanoparticles produced by laser floating zone and laser ablation in liquids, respectively. The photoluminescence (PL) and PL excitation (PLE) were investigated at room temperature (RT). PL spectra exhibit the characteristic lines in UV, blue/green, red and NIR regions of the Tm(3+) (4f(12)) under resonant excitation into the high energy (2S+1)LJ multiplets. Under NIR excitation (980 nm), the samples placed in air display an intense NIR at ∼800 nm due to the (1)G4→(3)H5/(3)H4→(3)H6 transitions. Additionally, red, blue/green and ultraviolet UCL is observed arising from higher excited (1)G4 and (1)D2 multiplets. The power excitation dependence of the UCL intensity indicated that 2-3 low energy absorbed photons are involved in the UCL for low power levels, while for high powers, the identified saturation is dependent on the material size with a enhanced effect on the NPs. The temperature dependence of the UCL was investigated for single crystals and targets used in the ablation. An overall increase of the integrated intensity was found to occur between 12 K and the RT. The thermally activated process is described by activation energies of 10 meV and 30 meV for single crystals and targets, respectively. For the NPs, the UCL was found to be strongly sensitive to pressure conditions. Under vacuum conditions, instead of the narrow lines of the Tm(3+), a wide blackbody radiation was detected, responsible for the change in the emission colour from blue to orange. This phenomenon is totally reversible when the NPs are placed at ambient pressure. The UCL/blackbody radiation in the nanosized material exhibits non-contact pressure colour-based sensor characteristics. Moreover, tuning the color of the blackbody radiation in the nanoparticles by harvesting the low energy photons into the visible spectral region was found to be possible by adjusting the excitation power, paving the way for further developments of these nanoparticles for lighting and photovoltaic applications.
The nutritional status of patients with chronic obstructive pulmonary disease. (1981)

The nutritional status of 38 patients with chronic obstructive pulmonary disease (COPD) was assessed by dietary intake, anthropometric measurements biochemical analysis, and immunologic testing. The mean intakes for 9 nutrients were significantly greater than the 1974 Recommended Dietary Allowances of the National Academy of Sciences. Results of the anthropometric measurements for usual weight for height, fat stores, and muscle mass were significantly less than standard. Of the 32 subjects evaluated for immunocompetence, 9 were anergic (induration, 0) on all 3 skin tests. The results of this study indicated that the marasmic type of protein calorie malnutrition is a common finding among patients with COPD, and that patients with COPD who are immunoincompetent may be more susceptible to mixed protein calorie malnutrition of the kwashiorkor-marasmus type.
Direct Observation of Gate-Tunable Dark Trions in Monolayer WSe<sub>2</sub> (2019)

Spin-forbidden intravalley dark excitons in tungsten-based transition-metal dichalcogenides (TMDCs), because of their unique spin texture and long lifetime, have attracted intense research interest. Here, we show that we can control the dark exciton electrostatically by dressing it with one free electron or free hole, forming the dark trions. The existence of the dark trions is suggested by the unique magneto-photoluminescence spectroscopy pattern of the boron nitride (BN)-encapsulated monolayer WSe<sub>2</sub> device at low temperature. The unambiguous evidence of the dark trions is further obtained by directly resolving the radiation pattern of the dark trions through back focal plane imaging. The dark trions possess a binding energy of ∼15 meV, and they inherit the long lifetime and large <i>g</i>-factor from the dark exciton. Interestingly, under the out-of-plane magnetic field, dressing the dark exciton with one free electron or hole results in distinctively different valley polarization of the emitted photon, as a result of the different intervalley scattering mechanism for the electron and hole. Finally, the lifetime of the positive dark trion can be further tuned from ∼50 ps to ∼215 ps by controlling the gate voltage. The gate-tunable dark trions usher in new opportunities for excitonic optoelectronics and valleytronics.

Stereoselective Synthesis of 1,3-Diols (2006)

Many polyketide-derived natural products contain a syn- or anti-1,3-diol unit. No general and simple approach exists for the flexible synthesis of polyols and other polyketide-derived structural units, therefore a multitude of methods for the stereoselective synthesis of 1,3-diols has been developed. Asymmetric homogeneous and heterogeneous hydrogenation and diastereoselective reduction, chain elongation, enzymatic and nonenzymatic desymmetrization, or dynamic kinetic resolution are some of these methods. The development of different methods to synthesize these 1,3-diols stereoselectively is important, as often small structural changes in a molecule result in low yields or low stereoselectivity with a known method. This review article highlights some of the recent developments in this field.
Tetraarylborate polymer networks as single-ion conducting solid electrolytes (2015)

A new family of solid polymer electrolytes based upon anionic tetrakis(phenyl)borate tetrahedral nodes and linear bis-alkyne linkers is reported. Sonogashira polymerizations using tetrakis(4-iodophenyl)borate, tetrakis(4-iodo-2,3,5,6-tetrafluorophenyl)borate and tetrakis(4-bromo-2,3,5,6-tetrafluorophenyl)borate delivered highly cross-linked polymer networks with both 1,4-diethynylbeznene and a tri(ethylene glycol) substituted derivative. Promising initial conductivity metrics have been observed, including high room temperature conductivities (up to 2.7 × 10<sup>-4</sup> S cm<sup>-1</sup>), moderate activation energies (0.25-0.28 eV), and high lithium ion transport numbers (up to <i>t</i><sub>Li<sup>+</sup></sub> = 0.93). Initial investigations into the effects of important materials parameters such as bulk morphology, porosity, fluorination, and other chemical modification, provide starting design parameters for further development of this new class of solid electrolytes.
Environmental Control Issues in a New Energy-Efficient Building (2014)

The availability of adjustable lighting controls, with options other than “on” and “off,” have been associated with increased energy savings. In the present study, we describe the way customizable, networked lighting controls are actually used in a recently built research facility that received a formal designation for sustainable design (LEED Gold). In addition to usage patterns, we explored occupants’ knowledge of control operation as well as the expectancies of nonoccupants. We also identified a variety of features that, if redesigned in accordance with HF/E principles, might lead to reduced lighting usage.
Contribution of an arsenal of virulence factors to pathogenesis of Pseudomonas aeruginosa infections (2011)

Pseudomonas aeruginosa is an increasingly prevalent opportunistic pathogen that causes a variety of nosocomial infections, life-threatening diseases in immunocompromised persons and chronic pulmonary infections in cystic fibrosis patients. The organism’s virulence depends on an arsenal of cell-associated and extracellular factors determining the pathogenesis of infections as multifactorial. Most P. aeruginosa infections are both invasive and toxinogenic. Many of the extracellular virulence factors (proteases, exotoxin A, pyocyanin, siderophores, hemolysins) required for tissue invasion and dissemination of P. aeruginosa are controlled by quorum sensing (QS) that enable the bacteria to produce these factors in a coordinated, cell-density-dependent manner and overwhelm the host defense mechanisms during acute infection. Sometimes, QS also contributes to biofilm formation and thus participates in pathogenesis of chronic infection. This system is recognized to be a global regulatory network controlling the expression of a large number of virulence genes either directly or indirectly. Two-component sensor kinases such as RetS, LadS and GacS are also controlling the production of virulence factors as well as the switch from acute to chronic infection. The present review describes the known virulence determinants of P. aeruginosa, the stages of infection as well as the importance of QS in the pathogenesis of P. aeruginosa infection.
Evaluation of the C6 Peptide Enzyme-Linked Immunosorbent Assay for Individuals Vaccinated with the Recombinant OspA Vaccine (2002)

The C6 enzyme-linked immunosorbent assay (ELISA), based on a peptide (C6) that reproduces the sequence of invariable region 6 of VlsE, the antigenic variation protein of Borrelia burgdorferi, has been shown to be a sensitive and specific test for the serologic diagnosis of Lyme disease. We now report that none of 29 uninfected individuals vaccinated with the recombinant OspA vaccine had an antibody response to the C6 peptide. The C6 peptide ELISA can be used to diagnose Lyme disease in patients who have received the OspA vaccine.

Phase-contrast CT: fundamental theorem and fast image reconstruction algorithms (2006)

Phase-contrast x-ray computed tomography (CT) is an emerging imaging technique that can be implemented at third generation synchrotron radiation sources or by using a microfocus x-ray tube. Promising experimental results have recently been obtained in material science and biological applications. At the same time, the lack of a mathematical theory comparable to that of conventional absorption-based CT limits the progress in this field. We suggest such a theory and prove a fundamental theorem that plays the same role for phase-contrast CT as the Fourier slice theorem does for absorption-based CT. The fundamental theorem allows us to derive fast image reconstruction algorithms in the form of filtered backprojection (FBP).
Isomeric Cyclopropenes Exhibit Unique Bioorthogonal Reactivities (2013)

Bioorthogonal chemistries have provided tremendous insight into biomolecule structure and function. However, many popular bioorthogonal transformations are incompatible with one another, limiting their utility for studies of multiple biomolecules in tandem. We identified two reactions that can be used concurrently to tag biomolecules in complex environments: the inverse electron-demand Diels-Alder reaction of tetrazines with 1,3-disubstituted cyclopropenes, and the 1,3-dipolar cycloaddition of nitrile imines with 3,3-disubstituted cyclopropenes. Remarkably, the cyclopropenes used in these transformations differ by the placement of a single methyl group. Such orthogonally reactive scaffolds will bolster efforts to monitor multicomponent processes in cells and organisms.
Compact silicon TE-pass polarizer using rib waveguide adiabatic bends with side gratings (2019)

Effects of knockout of the receptor for advanced glycation end‐products on bone mineral density and synovitis in mice with intra‐articular fractures (2018)

Our group employed the mouse closed intra-articular fracture (IAF) model to test the hypothesis that the innate immune system plays a role in initiating synovitis and post-traumatic osteoarthritis (PTOA) in fractured joints. A transgenic strategy featuring knockout of the receptor for advanced glycation end-products (RAGE <sup>-/-</sup> ) was pursued. The 42 and 84 mJ impacts used to create fractures were in the range previously reported to cause PTOA at 60 days post-fracture. MicroCT (μCT) was used to assess fracture patterns and epiphyseal and metaphyseal bone loss at 30 and 60 days post-fracture. Cartilage degeneration, synovitis, and matrix metalloproteinase (MMP-3, -13) expression were evaluated by histologic analyses. In wild-type mice, μCT imaging showed that 84 mJ impacts led to significant bone loss at 30 days (p < 0.05), but recovered to normal at 60 days. Bone losses did not occur in RAGE<sup>-/-</sup> mice. Synovitis was significantly elevated in 84 mJ impact wild-type mice at both endpoints (30 day, p = 0.001; 60 day, p = 0.05), whereas in RAGE<sup>-/-</sup> mice synovitis was elevated only at 30 days (p = 0.02). Mankin scores were slightly elevated in both mouse strains at 30 days, but not at 60 days. Immunohistochemistry revealed significant fracture-related increases in MMP-3 and -13 expression at 30 days (p < 0.05), with no significant difference between genotypes. These findings indicated that while RAGE <sup>-/-</sup> accelerated recovery from fracture and diminished synovitis, arthritic changes were temporary and too modest to detect an effect on the pathogenesis of PTOA. © 2018 Orthopaedic Research Society.

A physiological model of glucose-insulin interaction in type 1 diabetes mellitus (1992)

A clinical model of glucose-insulin interaction in insulin-dependent diabetes mellitus has been developed for patient and medical staff education. The model attempts to reflect the underlying (patho)physiology of insulin action and carbohydrate absorption in quantitative terms such as insulin sensitivity, volume of glucose and insulin distribution and maximal rate of gastric emptying. The model's predictions also allow a 24 h simulation of patient blood glucose profiles to be generated. A description of the model is provided and its operation illustrated by clinical case studies of insulin-treated diabetic patients. The possible use of the model as a tool for automated insulin dosage adjustment is explored.
Avoiding and Treating Dermal Filler Complications Table 1. Classification of U.S. Food and Drug Administration–Approved Injectables (2006)

All fillers are associated with the risk of both early and late complications. Early side effects such as swelling, redness, and bruising occur after intradermal or subdermal injections. The patient has to be aware of and accept these risks. Adverse events that last longer than 2 weeks can be attributable to technical shortcomings (e.g., too superficial an implantation of a long-lasting filler substance). Such adverse events can be treated with intradermal 5-fluorouracil, steroid injections, vascular lasers, or intense pulsed light, and later with dermabrasion or shaving. Late adverse events also include immunologic phenomena such as late-onset allergy and nonallergic foreign body granuloma. Both react well to intralesional steroid injections, which often have to be repeated to establish the right dose. Surgical excisions shall remain the last option and are indicated for hard lumps in the lips and visible hard nodules or hard granuloma in the subcutaneous fat.
Magnesium-Nickel alloy for hydrogen storage produced by melt spinning followed by cold rolling (2012)

Severe plastic deformation routes (SPD) have been shown to be attractive for short time preparation of magnesium alloys for hydrogen storage, generating refined microstructures and interesting hydrogen storage properties when compared to the same materials processed by high-energy ball milling (HEBM), but with the benefit of higher air resistance. In this study, we present results of a new processing route for Mg alloys for hydrogen storage: rapid solidification followed by cold work. A Mg97Ni3 alloy was processed by melt spinning (MS) and by extensive cold rolling (CR). Submitting Mg97Ni3 ribbons between steel plates to cold rolling has shown to be a viable procedure, producing a thin cold welded foil, with little material waste. The as-processed material presents a high level of [002] fiber texture, a sub microcrystalline grain structure with a high density of defects, and also a fine dispersion of Mg2Ni nanoparticles. This refined microstructure allied to the developed texture resulted in enhanced activation and H-sorption kinetics properties.
Pharmacologic Management of Agitation in Alzheimer’s Disease (2003)

A large body of evidence has accrued that neuropsychiatric disturbances, such as agitation, are extremely common in Alzheimer's disease. These disturbances are associated with considerable morbidity including earlier nursing home admission, more rapid progression, exacerbation of functional and cognitive deficits, and increased caregiver distress. When attention to social or environmental causes, medical conditions, or other triggers of the behavioral disturbance fails to yield improvement, a role for medication may be indicated, whereby the most dominant behavioral target symptoms are matched to the most relevant medication class. Evidence is reviewed for various medication classes in treating agitation in the patient with Alzheimer's disease, and future treatment strategies may be aimed at delaying or preventing such neuropsychiatric disturbances.
Dynamic binary translation specialized for embedded systems (2010)

This paper describes the design and implementation of a novel dynamic binary translation technique specialized for embedded systems. Virtual platforms have been widely used to develop embedded software and dynamic binary translation is essential to boost their speed in simulations. However, unlike application simulation, the code generated for systems simulation is still slow because the simulator must replicate all of the functions of the target hardware. Embedded systems, which focus on providing one or a few functions, utilize only a small portion of the processor's features most of the time. For example, they may use a Memory Management Unit (MMU) in a processor to map physical memory to effective addresses, but they may not need paged memory support as in an OS. We can exploit this to specialize the dynamically translated code for more performance.
Hybrid Cell Adhesive Material for Instant Dielectrophoretic Cell Trapping and Long-Term Cell Function Assessment (2011)

Dielectrophoresis (DEP) for cell manipulation has focused, for the most part, on approaches for separation/enrichment of cells of interest. Advancements in cell positioning and immobilization onto substrates for cell culture, either as single cells or as cell aggregates, has benefited from the intensified research efforts in DEP (electrokinetic) manipulation. However, there has yet to be a DEP approach that provides the conditions for cell manipulation while promoting cell function processes such as cell differentiation. Here we present the first demonstration of a system that combines DEP with a hybrid cell adhesive material (hCAM) to allow for cell entrapment and cell function, as demonstrated by cell differentiation into neuronlike cells (NLCs). The hCAM, comprised of polyelectrolytes and fibronectin, was engineered to function as an instantaneous cell adhesive surface after DEP manipulation and to support long-term cell function (cell proliferation, induction, and differentiation). Pluripotent P19 mouse embryonal carcinoma cells flowing within a microchannel were attracted to the DEP electrode surface and remained adhered onto the hCAM coating under a fluid flow field after the DEP forces were removed. Cells remained viable after DEP manipulation for up to 8 d, during which time the P19 cells were induced to differentiate into NLCs. This approach could have further applications in areas such as cell-cell communication, three-dimensional cell aggregates to create cell microenvironments, and cell cocultures.

Glutamic Acid Production in Biotin-rich Media by Temperature-sensitive Mutants of<i>Brevibacterium lactofermentum</i>, a Novel Fermentation Process (1978)

Temperature-sensitive mutants were derived from Brevibacterium lactofermentum strain 2256 in a search for mutants which would produce a large amount of L-glutamic acid in biotin- rich media at the nonpermissive temperature. A total of 159 mutant strains was selected which showed adequate growth at 30°C but showed little or no growth at 37°C on minimal medium. Twenty of these were found to produce glutamic acid in a biotin-rich medium after a temperature shift from 30°C to 37°C, while the wild-type strain 2256 did not produce it under the same cultural condition. One of the typical mutant strains, Ts-88, produced approximately 2g/dl of glutamic acid from beet molasses (the yield > 55%) in the presence of 33 µg/liter of biotin when tempera- , ture was shifted from 30°C to 40°C during the cultivation. It was concluded that, by controlling only temperature during fermentation, glutamic acid production could be realized in media containing biotin-rich natural carbon sources, without any chemical control such as the addition of expensive surface-active agents or antibiotics. Characteristics and merits of the novel fermentation process are discussed.
