Removal of two sentinel nodes accurately stages the axilla in breast cancer (2003)

In early breast cancer, when there were multiple sentinel nodes, removal of two sentinel nodes significantly reduced the false-negative rate compared with removal of one node. Removing more than two sentinel nodes did not significantly reduce the false-negative rate further.

Location–Price Competition in Mobile Operator Market (2018)

In this paper, we propose a game-theoretic model of the mobile network market. The market is presented by three sides: primary mobile network operators (MNO), mobile virtual network operators (MVNO) and consumers of the services. MVNO are mobile operators without their own infrastructure. They buy resources from MNO and compete with other MVNO for the consumers selling a service in the mobile network market. We construct a two-stage game. In the first stage, MVNO (players) select the MNO, one or several, and then announce the price for their service for the consumers in this MNO. After the profile of prices is determined, the consumers are distributed among MVNOs following the logistic function. The equilibrium in this two-stage game is constructed. For identical consumers, the analytic formulas for the solution are derived.
LONG-TERM OUTCOMES AFTER “NON-CURATIVE” ENDOSCOPIC SUBMUCOSAL DISSECTION (ESD) FOR COLORECTAL ADENOCARCINOMA (2020)

Aims Endoscopic-submucosal-dissection(ESD)is a well-established technique for the management of early colorectal cancer(CRC).The advantage of ESD over endoscopic-mucosal-resection is related to the achievement of en-bloc/R0resection.After ESD,patients with positive resected margins(R1),deep submucosal involvement(>sm2)poor differentiation(G3),presence of neoplastic budding(B+)and lympho-vascular invasion(LV+)at histology are considered candidate for surgery(non-curative,NC-ESD) because of the significant risk of nodal involvement.Outcomes following NC-ESDs have never been assessed in the field of CR cancer,resulting in variable clinical management.The aim of our study is to report long-term outcomes after NC-ESD,regardless of post-endoscopic management.
Distributed intersection control based on Cooperative Awareness Messages (2021)

Autonomous intersection control received particular interest recently. Theoretically, such traffic light-free controls can greatly improve the throughput of intersections with autonomous vehicles. The objective of this paper is to show how even a simple intersection control algorithm is susceptible to communication imperfections through detailed modeling of the communication layers. Safety and sensitivity analyses were carried out using a distributed control architecture, where no central control units are present. The control relies only on data contained in standard Cooperative Awareness Messages. The vehicle ad-hoc network communication is simulated with multiple layers considering many critical factors like signal propagation, noise, channel load, and even faulty units. Simulation results suggest that autonomous intersection control is robust against minor faults or communication errors. On the other hand, significant communication breakdowns lead to collisions.
Arginine metabolism and urea synthesis in cultured rat skeletal muscle cells (1982)

Skeletal muscle is known to contain arginase, but, because this enzyme is also present in erythrocytes, the exact origin of arginine-derived ornithine in peripheral tissues is uncertain. In the present studies, skeletal muscle cells obtained from regenerating hindlimb muscle of adult rats were grown in primary tissue culture for approximately 3 wk and then studied in regard to changes in medium amino acid concentrations over a 48-h period. The consumption of arginine and serine was observed in parallel with the production of ornithine, proline, citrulline, glycine, and urea. Medium threonine and methionine concentrations were relatively constant over 48 h. Incubation of muscle cells with [U-14C]arginine resulted in the formation of [14C]ornithine and [14C]proline at rates at least 10-fold greater than could be accounted for by enzyme constituents of fetal calf serum. In addition, [guanido-14C]arginine was converted to [14C]urea and [U-14C]serine was converted to [14C]glycine. These studies indicate that cultured skeletal muscle cells contain a high arginase capacity and actively synthesize ornithine and urea from arginine.
Identification of Caligus parasites infesting Morone Labrax and its impact on fish health status and pathological alteration. (2021)

Objective: The present study was aimed to investigate sea lice infestation including morphometric, molecular identification, disease prevalence and pathological tissue alterations in wild Sea bass (Morone Labrax) naturally collected from Ezbet Elborg, Damietta province, Egypt from October 2018 to end of August 2019. Design: Descriptive study Fish: 120 wild seabass (Morone Labrax) Procedures: The collected fish from Ezbet Elborg area, Damietta province, Egypt were clinically and parasitological investigated for the prevalence of sea lice parasite with molecular identification of the collected parasite samples with study of the pathological alteration of the affected tissue. Results: The study revealed that 48 fish (40%) of the examined fish were infested with Caligus clemensi, while the higher prevalence recorded during summer season (57%) followed spring (33%), autumn (10%) and no recording during winter. The molecular identification using 18-S rDNA was done with phylogenetic analysis compared with the previously recorded caligus species on database confirming the same results of parasitology. Histopathological examination of gills, buccal cavity revealed that the gill arch contained congested blood vessels beside edema, hemorrhage and inflammatory cells infiltration due to parasitic infestation. Conclusions and clinical relevance: Caligus infestation in wild sea bass caused by Caligus clemensi lead to mortalities due to pathological tissue alterations in gills and buccal cavity.

The emission and excitation spectra of $\mathrm{Ba}{\mathrm{F}}_{2}$ doped with 0.3 and $3.0\phantom{\rule{0.3em}{0ex}}\mathrm{mol}\phantom{\rule{0.2em}{0ex}}%$ ${\mathrm{Pr}}^{3+}$ have been studied using synchrotron radiation in the range from $5\phantom{\rule{0.3em}{0ex}}\text{to}\phantom{\rule{0.3em}{0ex}}30\phantom{\rule{0.3em}{0ex}}\mathrm{eV}$. In $\mathrm{Ba}{\mathrm{F}}_{2}:{\mathrm{Pr}}^{3+}$ $(0.3\phantom{\rule{0.3em}{0ex}}\mathrm{mol}\phantom{\rule{0.2em}{0ex}}%)$ the lowest level of the $4f5d$ configuration of ${\mathrm{Pr}}^{3+}$ is located at $5.55\phantom{\rule{0.3em}{0ex}}\mathrm{eV}$ relative to the $^{3}H_{4},4f$ ground state. The $^{1}S_{0},4f$ level lies higher, at $5.77\phantom{\rule{0.3em}{0ex}}\mathrm{eV}$. Consequently the crystal shows two types of the ${\mathrm{Pr}}^{3+}$ emissions, one related to $5d\ensuremath{\rightarrow}4f$ transitions with a decay constant of $22\phantom{\rule{0.3em}{0ex}}\mathrm{ns}$, another related to slow transitions from the $^{3}P_{0}$ level. In $\mathrm{Ba}{\mathrm{F}}_{2}:{\mathrm{Pr}}^{3+}$ $(3.0\phantom{\rule{0.3em}{0ex}}\mathrm{mol}\phantom{\rule{0.2em}{0ex}}%)$ the lowest $5d$ state lies at $6.0\phantom{\rule{0.3em}{0ex}}\mathrm{eV}$, that is above the $^{1}S_{0}$ level. At $10\phantom{\rule{0.3em}{0ex}}\mathrm{K}$ the crystal shows cascade emission, i.e., $^{1}S_{0}\ensuremath{\rightarrow}^{1}I_{6}$ transitions followed by transitions from the $^{3}P_{0}$ level. At room temperature the second step of the cascade is quenched. It is shown that the energy shift of the $5d$ state as a function of ${\mathrm{Pr}}^{3+}$ concentration is due to the formation of ${\mathrm{Pr}}^{3+}$-based clusters at higher concentrations.

Diurnal and Phenological Changes in the Rate of Nitrogen Transportation Monitored by Bleeding in Field-GrownRice Plants (<i>Oryza sativa</i>L.) (2007)

Nitrogen uptake is essential for rice growth and yield. Thus, the development of a simple and rapid method for monitoring nitrogen absorption is strongly required. We examined the fundamental properties of nitrogen transportation monitored by bleeding, including diurnal and phenological changes, to discuss whether the analysis of bleeding sap could be used for monitoring nitrogen uptake by rice. The rate of nitrogen transportation monitored by bleeding was estimated from a combination of the nitrogen concentration in bleeding sap and bleeding rate. We found a clear diurnal change in the rate of nitrogen transportation monitored by bleeding; it was higher in the daytime than at night. In this study, the diurnal change innitrogen uptake was not influenced by soil temperature but by the light condition. The rate of nitrogen transportation monitored by bleeding showed a phenological change with a peak around the panicle formation stage, while the bleeding rate peaked at around heading and was correlated with root length. The nitrogen concentration in bleeding sap continued to decrease gradually from the early growth stage. The cumulative amount of nitrogen uptake estimated by the bleeding sap analysis was less than half of that estimated by the plant analysis before the maximum tiller number stage, but the difference between these values decreased with plant growth. There was a significant positive correlation between the cumulative amount of nitrogen uptake estimated by these analyses throughout the growing period.
Silsesquioxane-based 193 nm bilayer resists: characterization and lithographic evaluation (2005)

Polysilsesquioxane-based 193 nm positive bilayer resists are described. In this design Si for etch resistance is placed in every repeat unit and acid-labile protected and acidic groups (and polar units) are in the side chain, allowing to incorporate each lithographically critical functionality in sufficient quantity. Fluoroalcohol is employed as an acid group instead of carboxylic acid because of its more attractive dissolution properties. Polymers were carefully analyzed by <sup>19</sup>F, <sup>13</sup>C, and <sup>29</sup>Si NMR to determine composition and to quantify residual acetyl, silanol, and Q/T. Hydrogen-bonding between tertiary ester and fluoroalcohol in the polysilsesquioxanes was investigated by FT-IR and the effect of lactone incorporation on the thermal deprotection temperature elucidated. In order to better understand the dissolution behavior of exposed resist films, the silsesquioxane resist polymers were partially (ca. 30%) and fully deprotected in solution with acid and their dissolution kinetics investigated by using a quartz crystal microbalance (QCM). It has been found that the exposed areas of the silsesquioxane resists can have a very fast dissolution rate (R<sub>max</sub>) of >20,000 A/sec (or even >100,000 A/sec). Heating the fully deprotected model polymers to 150&deg;C did not reduce the dissolution rate much, suggesting thermal condensation of silanol end groups is insignificant. Model deprotected polymers containing triphenylsulfonium nonaflate were exposed to 254 nm radiation, baked, and subjected to QCM measurements in order to determine whether or not acid-catalyzed silanol condensation would reduce the dissolution rate. A combination of high dose and high temperature bake resulted in significant reduction of the dissolution rate in the silsesquioxane polymer containing a small trifluoroalcohol. However, the dissolution behavior of the polymer bearing a bulky norbornene hexafluoroalcohol was unaffected by exposure and bake. Chemical and development contrast curves were generated by using a temperature gradient plate and bake temperature effects investigated. While a postapply bake temperature variation from 95 to 130&deg;C did not affect the contrast (chemical and development) and sensitivity, a postexposure bake temperature effect was quite small. The process window of the silsesquioxane bilayer resists was comparable to that of a high performance commercial 193 nm single layer resist for both isolated and nested contact hole imaging, Superior performance of our silsesquioxane resist was demonstrated in patterned etch in comparison with a COMA-based bilayer resist.
Effect of Number of Readout Channels on the Performance of a Continuous Miniature Crystal Element (cMiCE) Detector (2006)

In this work we investigate how the intrinsic spatial resolution varies with the number of digitized readout channels for a 64 (8 times 8) channel detector using a statistics-based positioning algorithm. We report results for both 6 mm and 8 mm thick crystals. Three channel reduction schemes are explored. The simplest scheme is row and column summing (R-C sum) of the PMT channels. The second method is to only use channels with signals above a 1% threshold of the total signal (1% thres). The third method is to acquire a subset of PMT channels determined by the maximum signal channel (zone mask). The full width at half maximum (FWHM) intrinsic spatial resolution results for the central and corner sections of the detector are presented for each of the methods. All methods except R-C sum performed well for the central section of the detector. The 1% thres and zone mask schemes showed significant improvement for the corner section of the 6 mm thick crystal. All methods using a single depth LUT had difficulty in the corner region for the 8 mm thick crystal. We believe this is caused by depth dependent edge effects on the light response function. Initial results using a depth dependent look-up table show improved positioning performance.
High-voltage high-power resonant converter for electrostatic precipitator (2004)

A phase-controlled series-parallel resonant converter for electrostatic precipitators is described. Compared with the traditional line-frequency power supplies, the converter is smaller in size, higher in efficiency, and provides a faster transient response. The converter is digitally controlled and the possibility of spark control using a DSP algorithm is explored. Operating behavior of the power supply with the nonlinear precipitator load is experimented and investigated.
Coronary Stent Restenosis in Patients Treated With Cilostazol (2005)

Treatment with the drug cilostazol resulted in a significantly larger minimal luminal diameter and a significantly lower binary restenosis rate compared with placebo-treated patients. These favorable effects were apparent in patients at high risk for restenosis.
Transcriptional signatures in prefrontal cortex confer vulnerability versus resilience to food and cocaine addiction-like behavior (2021)

Addiction is a chronic relapsing brain disease characterized by compulsive reward-seeking despite harmful consequences. The mechanisms underlying addiction are orchestrated by transcriptional reprogramming in the reward system of vulnerable subjects. This study aims at revealing gene expression alterations across different types of addiction. We analyzed publicly available transcriptome datasets of the prefrontal cortex (PFC) from a palatable food and a cocaine addiction study. We found 56 common genes upregulated in the PFC of addicted mice in these two studies, whereas most of the differentially expressed genes were exclusively linked to either palatable food or cocaine addiction. Gene ontology analysis of shared genes revealed that these genes contribute to learning and memory, dopaminergic synaptic transmission, and histone phosphorylation. Network analysis of shared genes revealed a protein-protein interaction node among the G protein-coupled receptors (Drd2, Drd1, Adora2a, Gpr6, Gpr88) and downstream targets of the cAMP signaling pathway (Ppp1rb1, Rgs9, Pde10a) as a core network in addiction. Upon extending the analysis to a cell-type specific level, some of these common molecular players were selectively expressed in excitatory neurons, oligodendrocytes, and endothelial cells. Overall, computational analysis of publicly available whole transcriptome datasets provides new insights into the molecular basis of addiction-like behaviors in PFC.
High-Level Culturability of Epiphytic Bacteria and Frequency of Biosurfactant Producers on Leaves (2016)

The importance of biosurfactant production to the bacteria that live on waxy leaf surfaces as well as their ability to be accurately assessed using culture-based methodologies was determined by interrogating epiphytic populations by both culture-dependent and culture-independent methods. Biosurfactant production was much more frequently observed in cultured communities on leaves than in other nearby habitats, such as soil and water, suggesting that this trait is important to life on a leaf by altering either the leaf itself or the interaction of bacteria with water. While pseudomonads were the most common biosurfactant producers isolated, this habitat also selects for taxa, such as Chryseobacterium, for which this trait was previously unrecognized. The finding that most epiphytic bacterial taxa were culturable validates strategies using more classical culturing methodologies for their study in this habitat.

Specific Inhibition of p25/Cdk5 Activity by the Cdk5 Inhibitory Peptide Reduces Neurodegeneration<i>In Vivo</i> (2013)

The aberrant hyperactivation of Cyclin-dependent kinase 5 (Cdk5), by the production of its truncated activator p25, results in the formation of hyperphosphorylated tau, neuroinflammation, amyloid deposition, and neuronal death in vitro and in vivo. Mechanistically, this occurs as a result of a neurotoxic insult that invokes the intracellular elevation of calcium to activate calpain, which cleaves the Cdk5 activator p35 into p25. It has been shown previously that the p25 transgenic mouse as a model to investigate the mechanistic implications of p25 production in the brain, which recapitulates deregulated Cdk5-mediated neuropathological changes, such as hyperphosphorylated tau and neuronal death. To date, strategies to inhibit Cdk5 activity have not been successful in targeting selectively aberrant activity without affecting normal Cdk5 activity. Here we show that the selective inhibition of p25/Cdk5 hyperactivation in vivo, through overexpression of the Cdk5 inhibitory peptide (CIP), rescues against the neurodegenerative pathologies caused by p25/Cdk5 hyperactivation without affecting normal neurodevelopment afforded by normal p35/Cdk5 activity. Tau and amyloid pathologies as well as neuroinflammation are significantly reduced in the CIP-p25 tetra transgenic mice, whereas brain atrophy and subsequent cognitive decline are reversed in these mice. The findings reported here represent an important breakthrough in elucidating approaches to selectively inhibit the p25/Cdk5 hyperactivation as a potential therapeutic target to reduce neurodegeneration.

β-lactamases produced by amoxicillin-clavulanate-resistant enterobacteria isolated in Buenos Aires, Argentina: A new blaTEM gene (2014)

Resistance to β-lactam/β-lactamase inhibitors in enterobacteria is a growing problem that has not been intensively studied in Argentina. In the present work, 54/843 enterobacteria collected in a teaching hospital of Buenos Aires city were ampicillin-sulbactam-resistant isolates remaining susceptible to second- and third-generation cephalosporins. The enzymatic mechanisms present in the isolates, which were also amoxicillin-clavulanic acid (AMC)-resistant (18/54) were herein analyzed. Sequencing revealed two different variants of blaTEM-1, being blaTEM-1b the most frequently detected allelle (10 Escherichia coli, 3 Klebsiella pneumoniae, 2 Proteus mirabilis and 1 Raoultella terrigena) followed by blaTEM-1a (1 K. pneumoniae). Amoxicillin-clavulanate resistance seems to be mainly associated with TEM-1 overproduction (mostly in E. coli) or co-expressed with OXA-2-like and/or SHV β-lactamases (K. pneumoniae and P. mirabilis). A new blaTEM variant (TEM-163) was described in an E. coli strain having an AMC MIC value of 16/8μg/ml. TEM-163 contains Arg275Gln and His289Leu amino acid substitutions. On the basis of the high specific activity and low IC50 for clavulanic acid observed, the resistance pattern seems to be due to overproduction of the new variant of broad spectrum β-lactamase rather than to an inhibitor-resistant TEM (IRT)-like behavior.
LaCl{sub 3}:Ce scintillator for Gamma ray detection (2002)

In this paper, we report on a relatively new cerium doped scintillator - LaCl3 for gamma ray spectroscopy. Crystals of this scintillator have been grown using Bridgman method. This material when doped with 10% cerium has high light output (~50,000 photons/MeV) and fast principal decay time constant (~20 ns). Furthermore, it shows excellent energy resolution for gamma ray detection. For example, energy resolution as low as 3.2% (FWHM) has been achieved with 662 keV photons (137Cs source) at room temperature. Also high timing resolution (264 ps - FWHM) has been recorded with LaCl3-PMT and BaF2-PMT detectors operating in coincidence using 511 keV positron annihilation gamma ray pairs. Details of crystal growth, scintillation properties, and variation of these properties with cerium concentration are also reported.
