BUN and Creatinine (1990)

Urea and creatinine are nitrogenous end products of metabolism. Urea is the primary metabolite derived from dietary protein and tissue protein turnover. Creatinine is the product of muscle creatine catabolism. Both are relatively small molecules (60 and 113 daltons, respectively) that distribute throughout total body water. In Europe, the whole urea molecule is assayed, whereas in the United States only the nitrogen component of urea (the blood or serum urea nitrogen, i.e., BUN or SUN) is measured. The BUN, then, is roughly one-half (28/60 or 0.446) of the blood urea.The normal range of urea nitrogen in blood or serum is 5 to 20 mg/dl, or 1.8 to 7.1 mmol urea per liter. The range is wide because of normal variations due to protein intake, endogenous protein catabolism, state of hydration, hepatic urea synthesis, and renal urea excretion. A BUN of 15 mg/dl would represent significantly impaired function for a woman in the thirtieth week of gestation. Her higher glomerular filtration rate (GFR), expanded extracellular fluid volume, and anabolism in the developing fetus contribute to her relatively low BUN of 5 to 7 mg/dl. In contrast, the rugged rancher who eats in excess of 125 g protein each day may have a normal BUN of 20 mg/dl.The normal serum creatinine (sCr) varies with the subject's body muscle mass and with the technique used to measure it. For the adult male, the normal range is 0.6 to 1.2 mg/dl, or 53 to 106 μmol/L by the kinetic or enzymatic method, and 0.8 to 1.5 mg/dl, or 70 to 133 μmol/L by the older manual Jaffe reaction. For the adult female, with her generally lower muscle mass, the normal range is 0.5 to 1.1 mg/dl, or 44 to 97 μmol/L by the enzymatic method.
Closure in Knee Replacement Surgery. (2016)

Total Knee replacement (TKR) is one of the commonest arthroplasty surgeries performed. Various techniques of closures in TKR are described. This technical note describes an useful technique of achieving water tight closure in TKR. An optimal tension watertight closure also reduces the chances of dead space hematomas and infection. The author has described his technique where the soft tissues are never unduly compromised. In his experience the patient can be mobilized freely in bed and even allowed to sleep prone after first wound check.
Single-photon avalanche diode array with column-level time-to-digital converter for unmanned vehicle (2017)

This paper introduces a design of Geiger-mode SPAD array chip aiming at unmanned-vehicle LIDAR. In order to reduce the number of afterpulsings, active quenching is adopted to keep the SPAD off for a sufficiently long time after each avalanche. Through theory analysis and simulation, a TDC is shared by a column of SPADs to improve the fill factor of photosensitive parts. The monolithic array chip is designed in the SMIC 0.13 μm CIS CMOS technology. Simulations proved that the sensor has a frame rate of over 30 fps and a measurement range of 250 m above, while still keeping high measurement precision.
Preliminary study of oncogene expressions in endometrial cancers. Aberrant estrogen receptor gene and erbB-2 expressions. (1995)

We studied the expressions of aberrant epidermal growth factor receptor (EGFR) gene or erbB-2, which is highly homologous to EGFR gene, and erbA or estrogen receptor (ER) gene, which is highly homologous to erbA, as a preliminary study, to know which oncogene expressions are associated with the development of endometrial cancers. ErbB-2 mRNA lacked only extracellular domain (EX), suggesting the lack of downregulation of erbB-2 expression by a ligand, which led to regulated tyrosine kinase activity. Mutated DNA binding domain of ER mRNA were found in 3 of the 13 cases, suggesting the promotion disorder of estrogen-inducible proteins in these 3 endometrial cancers. The behavior of aberrant erbB-2 and ER gene co-expressions is considered of similar to that of erbA and erbB co-expressions in the chicken introduced by the avian erythroblastosis virus, which leads to the development of erythroblastosis in the chick, and seems to be associated with the development of endometrial cancer.
Mobile station emergency locating in GSM (2002)

The positioning of a mobile station (MS) will become mandatory in the US in the near future to support enhanced emergency calls (E911). Also a lot of other applications are foreseen for the location service, when implemented. In the US a five-year, three-phase implementation of the E911 services is the most likely scenario. The authors study the feasibility of the Global System for Mobile Communications (GSM) for the MS emergency locating in each of the three phases. The results are relevant to all GSM based systems, i.e., to DCS 1800 and to PCS 1900. The TDMA based GSM offers some inherent means of calculating the location of the MS. The serving cell is already known by the mobile switching centre (MSC) and if wanted also by the operation and maintenance center (OMC). A set of measurement functions is already implemented in the MS that can be used to locate it more accurately. We investigate the use of timing advance (TA) and observed timing difference (OTD). By using the existing measurement functions the complexity of the handsets and the network does not increase much and additional costs remain moderate.
Lymphocyte responses to retinal-specific antigens in uveitis patients and healthy subjects (1988)

A modified procedure for measuring human lymphocyte responses to retinal antigens was introduced and found to be highly sensitive. The main modifications are the use of round bottom culture wells, high antigen concentrations (up to 100 micrograms/ml) and extended incubation time (up to 9 days). Using this procedure, the majority of patients with uveitis, as well as a large proportion of healthy donors were found to respond positively (S.I. greater than or equal to 2.0) toward S-antigen and interphoto-receptor retinoid-binding protein. The responses to the retinal antigens were further enhanced by enriching the cultured lymphocytes for the helper/inducer subset. The responses to the retinal antigens were inferior to those against tuberculin (PPD), in particular in subjects who had been inoculated with BCG. The "secondary" responses to PPD were always higher in magnitude, were stimulated by markedly lower concentrations of antigen and were detected earlier in culture. The notion that the responses to retinal antigen in healthy donors are "primary" in nature was further supported by the findings that (a) lymphocytes from cord blood samples resembled adult lymphocytes in their response to S-Ag and (b) healthy donor lymphocytes which were prestimulated in vitro with S-Ag reacted to this protein by a specific "secondary" fashion. The possible involvement of lymphocytes with reactivity toward retinal antigens in pathogenic autoimmune processes in the eye is discussed.
Ubiquitous UHF monitoring system for partial discharge detection and trending (2015)

Ubiquitous partial discharge (PD) detection in electrical power assets is needed to provide predictive maintenance for insulators in smart grid critical assets. A low cost solution is discussed that uses simple electronics and algorithms to interpret ultra-high frequency (UHF) signals as a combination of external noise, asymmetric partial discharge (such as corona and other surface discharges), and symmetric partial discharge. The paper describes a device using three UHF frequency bands and a logarithmic detector to provide baseband signal to a digital signal processor (DSP). The DSP employs discrete Fourier transform (DFT) methods to obtain a rapid and succinct quantification of the contribution to the UHF signal from noise sources vs. surface and internal discharge activity. While UHF methods cannot be calibrated in the sense of IEC60270, an apparatus and method for normalizing the response of in situ systems is discussed.
A New Subfamily of Sucrose Transporters, SUT4, with Low Affinity/High Capacity Localized in Enucleate Sieve Elements of Plants (2000)

A new subfamily of sucrose transporters from Arabidopsis (AtSUT4), tomato (LeSUT4), and potato (StSUT4) was isolated, demonstrating only 47% similarity to the previously characterized SUT1. SUT4 from two plant species conferred sucrose uptake activity when expressed in yeast. The K(m) for sucrose uptake by AtSUT4 of 11.6 +/- 0.6 mM was approximately 10-fold greater than for all other plant sucrose transporters characterized to date. An ortholog from potato had similar kinetic properties. Thus, SUT4 corresponds to the low-affinity/high-capacity saturable component of sucrose uptake found in leaves. In contrast to SUT1, SUT4 is expressed predominantly in minor veins in source leaves, where high-capacity sucrose transport is needed for phloem loading. In potato and tomato, SUT4 was immunolocalized specifically to enucleate sieve elements, indicating that like SUT1, macromolecular trafficking is required to transport the mRNA or the protein from companion cells through plasmodesmata into the sieve elements.
Recovery of airway patency after obstruction in normal infants. (1981)

We examined the characteristics of spontaneous restoration of airflow after airway obstruction during neck flexion in normal sleeping infants. In 22 of 27 episodes of complete airway obstruction in 5 of 8 infants, there was some resumption of airflow, although the angle of neck flexion was maintained. The airway reopening was usually delayed, after 1 to 3 obstructed inspiratory efforts, and usually without evidence of behavioral arousal. The time course of this delayed response suggested chemoreceptor mediation. In those trials where arousal was observed, airflow resumed immediately. Our observations suggested that activation of the genioglossus and other airway-maintaining muscles leads to airway reopening neck flexion in infants and that tonic genioglossus activity maintains airway patency. These observations represented the first description of restoration of airway patency after airway occlusion in infants.
DROP: An Open-Source Project towards Distributed SW Router Architectures (2009)

In this work, our main objective is to explore how Software Routers (SRs) can deploy advanced and flexible paradigms for supporting novel control plane functionalities and applications. To this purpose, we investigate and study a new open-source SW framework, namely Distributed SW ROuter Project (DROP), which aims at developing and enabling a novel distributed paradigm for IP-router control and management. DROP is partially based on the main guidelines of the IETF ForCES standard, and it allows building logical network nodes through the aggregation of multiple SRs, which can be devoted to packet forwarding or control operations. In addition to the original ForCES design, DROP will aim at extending router distribution and aggregation concepts by moving them at a network-wide scale in order to enable and to support value-added services for next-generation networks.
Methodology to Derive Resource Aware Context Adaptable Architectures for Field Programmable Gate Arrays (2021)

The design of a common architecture that can support multiple data-flow patterns (or contexts) embedded in complex control flow structures, in applications like multimedia processing, is particularly challenging when the target platform is a Field Programmable Gate Array (FPGA) with a heterogeneous mixture of device primitives. This thesis presents scheduling and mapping algorithms that use a novel area cost metric to generate resource aware context adaptable architectures. Results of a rigorous analysis of the methodology on multiple test cases are presented. Results are compared against published techniques and show an area savings and execution time savings of 46% each.
Dielectric mapping of a Pb(Ni1/3Nb2/3)O3–PbZrO3–PbTiO3 ternary phase spread (2002)

Lead perovskite compounds possess very rich and complex phase diagrams. They also have great potential in a variety of commercial applications. However, due in part to the very complicated nature of these materials, very few systematic studies of their ternary phase diagrams with respect to electrical properties have been performed. In this letter, we report the microwave dielectric property mapping of a ternary Pb(Ni1/3Nb2/3)O3–PbZrO3–PbTiO3 composition spread using a scanning evanescent microwave probe. We identified composition regions with dielectric constants higher than 600 at 1 GHz.

Biopolymers for hydrogels in cosmetics: review (2020)

Hydrogels are cross-linked networks of macromolecular compounds characterized by high water absorption capacity. Such materials find a wide range of biomedical applications. Several polymeric hydrogels can also be used in cosmetics. Herein, the structure, properties and selected applications of hydrogels in cosmetics are discussed in general. Detailed examples from scientific literature are also shown. In this review paper, most common biopolymers used in cosmetics are presented in detail together with issues related to skin treatment and hair conditioning. Hydrogels based on collagen, chitosan, hyaluronic acid, and other polysaccharides have been characterized. New trends in the preparation of hydrogels based on biopolymer blends as well as bigels have been shown. Moreover, biopolymer hydrogels employment in encapsulation has been mentioned.
Role of teat dips and hygiene in mastitis control. (1977)

The primary sources of mastitis pathogens are infected quarters, chapped, sore, or eroded teat ends, and the environment. The major means of transfer of the most predominant mastitis pathogens is the milking routine. Methods are available to reduce the number of organisms normally transferred during each of the procedures. However, with the exception of teat cup pasteurization, the application of hygienic procedures in herds where teat dipping is practiced did not result in additional beneficial effects. Effectiveness of 4% chlorine, 0.5 and 1% iodine, and 0.5% chlorhexidine teat dips has been demonstrated in field trials and should be the preferred products in a mastitis control program. Most gram-negative organisms get on teats by direct contact with the bedding. In herds with clinical coliform mastitis, changing the bedding material has been associated with fewer clinical mastitis cases.
A Correlation-Based Transition Model using Local Variables (2006)

A new correlation-based transition model has been developed, which is based strictly on local variables. As a result, the transition model is compatible with modern computational fluid dynamics (CFD) approaches, such as unstructured grids and massive parallel execution. The model is based on two transport equations, one for intermittency and one for the transition onset criteria in terms of momentum thickness Reynolds number. The proposed transport equations do not attempt to model the physics of the transition process (unlike, e.g., turbulence models) but from a framework for the implementation of correlation-based models into general-purpose CFD methods.
Evaluating tag-based information access in image collections (2012)

The availability of social tags has greatly enhanced access to information. Tag clouds have emerged as a new "social" way to find and visualize information, providing both one-click access to information and a snapshot of the "aboutness" of a tagged collection. A range of research projects explored and compared different tag artifacts for information access ranging from regular tag clouds to tag hierarchies. At the same time, there is a lack of user studies that compare the effectiveness of different types of tag-based browsing interfaces from the users point of view. This paper contributes to the research on tag-based information access by presenting a controlled user study that compared three types of tag-based interfaces on two recognized types of search tasks -- lookup and exploratory search. Our results demonstrate that tag-based browsing interfaces significantly outperform traditional search interfaces in both performance and user satisfaction. At the same time, the differences between the two types of tag-based browsing interfaces explored in our study are not as clear.
Central Nervous System Demyelinating Disease Protection by the Human Commensal <i>Bacteroides fragilis</i> Depends on Polysaccharide A Expression (2010)

The importance of gut commensal bacteria in maintaining immune homeostasis is increasingly understood. We recently described that alteration of the gut microflora can affect a population of Foxp3(+)T(reg) cells that regulate demyelination in experimental autoimmune encephalomyelitis (EAE), the experimental model of human multiple sclerosis. We now extend our previous observations on the role of commensal bacteria in CNS demyelination, and we demonstrate that Bacteroides fragilis producing a bacterial capsular polysaccharide Ag can protect against EAE. Recolonization with wild type B. fragilis maintained resistance to EAE, whereas reconstitution with polysaccharide A-deficient B. fragilis restored EAE susceptibility. Enhanced numbers of Foxp3(+)T(reg) cells in the cervical lymph nodes were observed after intestinal recolonization with either strain of B. fragilis. Ex vivo, CD4(+)T cells obtained from mice reconstituted with wild type B. fragilis had significantly enhanced rates of conversion into IL-10-producing Foxp3(+)T(reg) cells and offered greater protection against disease. Our results suggest an important role for commensal bacterial Ags, in particular B. fragilis expressing polysaccharide A, in protecting against CNS demyelination in EAE and perhaps human multiple sclerosis.
Coordinate control of distributed generation and power electronics loads in microgrid (2016)

Droop control is an effective power sharing control scheme for islanding microgrid. With the load increasing, the microgrid may face overload challenge. Dispatch system should schedule energy storage system to provide power reserve or load shedding for preventing islanding microgrid black out. This paper proposes a coordinate control scheme for distributed generation (DG) units and active loads to provide instantaneous reserve for microgrid. A load frequency trimming control is invested to participate into supply-demand balance service to maintain and enhance the system reliability, only using control variables of the converter itself that can be measured locally. Through the frequency trimming control strategy, supply-demand balance can be realized automatically, and microgrid can avoid malfunction. Therefore, the communication links, dispatch system, and additional energy storage system can be excluded. Matlab simulations are presented to show the effectiveness of the proposed scheme performance in islanding microgrid.
Distribution of 5,5 dimethyl-2,4-oxazolidinedione (DMO) in intraocular and cerebrospinal fluids of rabbits. 3. Effect of ammonium chloride and probenecid. (1967)

The effect of ammonium chloride (systemic acidosis) and probenecid on the distribution of DMO in intraocular and cerebrospinal fluids has been studied. These drugs increased the level of DMO in intraocular fluids so that DMO was found in excess of plasma levels at plasma levels which normally result in a deficit of DMO in intraocular fluids. Their action seemed to be explained in part by a blocking of the secretion out of DMO at the ciliary process and perhaps an increased diffusion in the posterior segment of the eye. Probenecid may well affect the distribution of DMO in cerebrospinal fluid. It appears that the use of the partition of DMO between compartments as an indication of pH should be substantiated by another method for each set of experimental conditions.
<title>Minimal cost WDM network for incremental traffic</title> (1999)

A wavelength division multiplexed network is considered for arbitrary topologies. The network allows optical signals to pass through nodes, which often results in less electronic and opto-electronic equipment than networks that do not, i.e., networks that only switch traffic electronically. A disadvantage of having optical pass through is that there is less capability to switch tributary traffic streams and so there may be more blocking. However, it is shown that the network operates as well as a network with only electronic switching under a particular incremental traffic model. Examples are given that shows that the network can have lower cost when the cost is dominated by the line terminating equipment. A simple heuristic design algorithm is also given to configure the network to minimize its cost.
SYNTHESIS OF SELENIUM-DERIVATIZED NUCLEOSIDES AND OLIGONUCLEOTIDES FOR X-RAY CRYSTALLOGRAPHY (2001)

We report here the synthesis of nucleoside and oligonucleotide analogs containing selenium, which serves as an anomalous scattering center to enable MAD phase determination in nucleotide X-ray crystallography. We have developed a phase transfer approach to introduce the selenium functionality in A, C, G, T, and U nucleosides at 5'-positions. In the incorporation of the selenium functionality, the leaving groups (bromide, mesyl, and tosyl) were readily displaced by sodium selenide, sodium diselenide, and sodium methyl selenide with yields higher than 90%. Selenium-derivatized oligonucleotides have been synthesized via phosphoramidite chemistry.
