New Lines of the 3d-4f Transitions in Na II (1965)

Alcohol which, at first, is part of great ceremonies, parties, get-togethers, is now becoming an important issue, for the number of women who consume alcoholic beverages has increased, and consequently the number of pregnant women, considering that not only the mother's body but also the one of the child that is being formed, are under metabolic changes, and inevitably will be a target for acquired alcohol alterations (intake). During the human development, it is important to take into consideration the pregnancy stage and depending on it, the individual becomes susceptible to teratogenic agents. This paper aims at providing some contribution related to this social issue bringing knowledge on the action of alcohol on the fetus alterations, from the slightest (irritability, lack of attention, mobility deficiency) until Fetal Alcoholic Syndrome (F.A.S.) and also tries to analyse the extent of people knowledge on the consequences of alcohol effects over pregnant women bodies and the possible changes that may occur with the fetus. In order to make this study possible, interviews have been made by the use of forms with a population sample of about 100 people living in the northern, western, southern and interior low land regions. We have also visited some public and private institutions (23) on those regions, interviewing nurses in paediatric wards, aiming at identifying the difficulties found related to the diagnosis and management towards F.A.S.

Cloning and Characterization of a Transcription Factor That Binds to the Proximal Promoters of the Two Mouse Type I Collagen Genes (1997)

We have used the yeast one-hybrid system to clone transcription factors that bind to specific sequences in the proximal promoters of the type I collagen genes. We utilized as bait the sequence between −180 and −136 in the pro-α2(I) collagen promoter because it acts as a functional promoter element and binds several DNA-binding proteins. Three cDNA clones were isolated that encoded portions of the mouse SPR2 transcription factor, whereas a fourth cDNA contained a potential open reading frame for a polypeptide of 775 amino acids and was designated BFCOL1. Recombinant BFCOL1 was shown to bind to the −180 to −152 segment of the mouse pro-α2(I) collagen proximal promoter and to two discrete sites in the proximal promoter of the mouse pro-α1(I) gene. The N-terminal portion of BFCOL1 contains its DNA-binding domain. DNA transfection experiments using fusion polypeptides with the yeast GAL4 DNA-binding segment indicated that the C-terminal part of BFCOL1 contained a potential transcriptional activation domain. We speculate that BFCOL1 participates in the transcriptional control of the two type I collagen genes.

Bacterial chondronecrosis with osteomyelitis in broilers: Influence of sires and straight-run versus sex-separate rearing (2014)

Two experiments (E1, E2) were conducted to compare the influence of sires (sire A on dam C vs. sire B on dam C) and straight-run versus sex-separate rearing on the incidence of bacterial chondronecrosis with osteomyelitis (BCO) in broilers. Fertile eggs from commercial breeder flocks were incubated and hatched at the University of Arkansas Poultry Research Hatchery. Male and female chicks were reared together (straight-run) or separately (sex-separate) in 3 × 3 m pens on litter or flat wire flooring with 65 (E1) or 60 (E2) birds per pen. Necropsies revealed lesions that are pathognomonic for BCO in ≥98% of the birds that became lame. The SigmaStat Z-test was used to compare cumulative BCO incidences through 8 wk of age. For birds reared on litter, the incidences of BCO were low regardless of cross or sex (range: 1.7 to 5.1%; P ≥ 0.6). Within a cross and sex, rearing the broilers straight-run versus sex-separate on wire flooring did not significantly affect the incidence of BCO. Significant incidences of BCO did not develop until after d 40. Males from the sire A cross developed a higher incidence of BCO than males from the sire B cross in E1 (27 vs. 17%, respectively; P = 0.009) but not in E2 (28.5 vs. 22.6%, respectively; P = 0.141). In both experiments, males from the sire A cross developed higher incidences of BCO than females from the sire B cross (27 vs. 11.9%, in E1; 28.5 vs. 14.8%, in E2). With the sexes pooled, broilers from the sire A cross consistently developed higher incidences of BCO than broilers from the sire B cross (21.4 vs. 14.9%, P = 0.005 in E1; 26.5 vs. 18.7%, P = 0.003 in E2). High susceptibilities to both femoral head (all femoral head necrosis = 66 to 85% incidences) and tibial head (all tibial head necrosis = 81 to 96% incidences) BCO lesions were demonstrated in lame birds from both sexes and crosses. This study supports a sire influence on the susceptibility of broilers to BCO. Sire lines can be chosen to reduce BCO susceptibility when broilers are grown beyond 6 wk of age.
Isolation and characterization of psychrotolerant denitrifying bacteria for improvement of nitrate removal in woodchip bioreactors treating agricultural drainage water at low temperature (2021)

Nitrate removal was enhanced by the addition of isolated and pre-grown psychrotolerant denitrifiers at low temperature (5 °C).
An Engineering Approach to Utilize Fiber Optics Telemetry Enabled Coiled Tubing (ACTive Technology) in Well Testing and Sand Stone Matrix Stimulation - First Time in the World (2012)

Abstract For the last several years, viscous pills, polymer based, were used to kill the wells during the workover operation in the tronian formation existing in the eastern desert of Egypt. These polymer pills have negatively affected the wells productivity by blocking the pore throats and reducing the permeability. As an example, the well A-1 was producing 300 bpd (Gross) which declined dramatically after a workover operation which included the viscous polymer pills to produce only 20 bopd. An engineering study was carried out to identify the main reason for the decline in the production. Several experiments were performed in the lab in order to simulate the filter cake using formation samples and evaluate the effect of the polymer being injected on the sandface permeability. An engineered solution was designed to break the polymer subsequently pumped in the formation and stimulate the matrix in order to recover and enhance the oil production. The remedial work was executed using a Fiber Optics Telemetry Enabled Coiled Tubing (FOTECT) system to optimize the treatment leveraging on downhole real time measurements. This paper describes the first application of FOTECT in sandstone formations, involving: The sandstone matrix stimulation operation. Measuring both bottom hole pressure and temperatures at static and dynamic conditions during the entire operation. Accurate depth correlation to achieve optimum placement of the treatment fluids Monitor the chemical reactions in real time of the engineered treatment fluid. Monitor the diversion performance during Sand Stone stimulations and the timing required for efficient reactions. Qualitative production allocation of the interval as a response to the treatment fluids Evaluation of the skin value real-time while executing matrix stimulation. Pressure transient analysis in real-time enabling the standard output of a well test (permeability, skin, Pressure, and reservoir boundaries). The experience demonstrates that use of real-time downhole measurements during the CT treatment allows: a) the evaluation of the well performance before and after the treatment, b) enables optimization of the treatment as it is executed, based on the formation response, enhancing the chance for a successful intervention, and c) provides an added alternative to perform a well testing operation right after the treatment, thus, obtaining valuable information to update the reservoir model.
Fratture dell’arto inferiore e fratture distali della zona di accrescimento in età pediatrica (2005)

Riassunto Le fratture della tibia e del perone distale che coinvolgono la cartilagine di accrescimento non sono cosi frequenti da permettere ai chirurghi ortopedici di trattarne un numero significativo. Questa e di per se una ragione determinante per dedicare un capitolo allo studio anatomico e alla valutazione del meccanismo di tali lesioni, cosi come alle tecniche di imaging coinvolte. E quindi possibile definire il trattamento piu appropriato e le linee guida per prevenire e trattare le complicanze delle fratture di caviglia nei bambini. Nel descrivere i passaggi che il chirurgo ortopedico deve intraprendere prima di decidere il migliore trattamento, l’Autore di questo capitolo si e posto l’obiettivo di contribuire a una chiara comprensione delle tecniche principali necessarie per la corretta gestione delle fratture dell’arto inferiore e della zona di accrescimento in eta pediatrica.

Burden of Infectious Complications after Upper Extremity Allotransplantation (2018)

Introduction Risk-to-benefit ratio of upper extremity allotransplantation (UEA), a non-vital transplantation procedure, remains to be clarified, as concerns have been raised regarding infectious, metabolic and malignant complications of lifelong immunosuppression. The aim of this study was to provide a relevant assessment of the infectious risk in UEA recipients. Infectious complications in UEA recipients were analyzed and compared to that of kidney transplant (KT) recipients who have the lowest rate of infections among the different populations of solid organ transplant recipients. Patients and Methods Matched cohort study among UEA and KT recipients from the prospectively maintained “International Registry on Hand and Composite Tissue Transplantation” (IRHCTT) and the French “Données Informatisées et VAlidées en Transplantation” (DIVAT) database. All UEA recipients reported to the IRHCTT between 1998 and 2016 were matched with KT recipients (1:5), according to age (±5 years), sex, CMV serostatus of donor and recipient and (depleting or not depleting) induction. Incidence and characteristics of all infectious events reported to the databases at three posttransplant periods (0-6 months, 7-12 months, >12 months) were analyzed. Results and Discussion Sixty-one UEA recipients were matched with 305 KT recipients. Mean (±SD) follow-up of UEA and KT recipients was 2583±1876 and 2230±1792 days, respectively (p=0.16). Immunosuppression regimen at 3 months posttransplant was similar. The number of acute rejection episodes during follow-up was higher in UEA recipients than in KT recipients (1.3±1.6 vs 0.4±0.7, p<0.01). During follow-up, 30 (50.8%) UEA recipients presented a total of 61 infectious events while 129 (42.3%) KT recipients presented 243 infectious events. Incidence rate of infectious events was higher in UEA recipients than in KT recipients during the first 6 months posttransplant (3.27 vs 1.95 events/1000 transplant-days, p=0.01). Thereafter, incidence rates of infections did not significantly differ between UEA and KT recipients: 0.61 vs 0.45 events/1000 transplant-days (7th-12th month posttransplant, p=0.5) and 0.15 vs 0.21 events/1000 transplant-days (>12th month posttransplant, p=0.11), respectively. Distribution of sites of infections was significantly different: while mucocutaneous infections predominated among UEA recipients at each of the three posttransplant periods (representing 28.6%, 50% and 30% of infectious events, respectively), urinary tract infections (28.6%, 23.8% and 33.9%) and pneumonia (17.3%, 42.9% and 28.2%) predominated among KT recipients. Conclusion Incidence rate of infectious events is higher in UEA recipients than in KT recipients during the first 6 months posttransplant. After the first 6 months posttransplant, incidence of infections is low, at worst equivalent to the incidence observed in young KT recipients. Distribution of infectious syndromes suggests less severe infections in UEA than in KT recipients.
Topological Control on Silicates’ Dissolution Kinetics (2016)

Like many others, silicate solids dissolve when placed in contact with water. In a given aqueous environment, the dissolution rate depends on the composition and the structure of the solid and can span several orders of magnitude. Although the kinetics of dissolution depends on the complexities of both the dissolving solid and the solvent, a clear understanding of which structural descriptors of the solid control its dissolution rate is lacking. By pioneering dissolution experiments and atomistic simulations, we correlate the dissolution rates-ranging over 4 orders of magnitude-of a selection of silicate glasses and crystals to the number of chemical topological constraints acting between the atoms of the dissolving solid. The number of such constraints serves as an indicator of the effective activation energy, which arises from steric effects, and prevents the network from reorganizing locally to accommodate intermediate units forming over the course of the dissolution.

Chemical Generation of C602- and Electron Transfer Mechanism for the Reactions with Alkyl Bromides (1996)

A simple solution-phase method that uses chemically generated p-benzoquinone dianions (Q2-) as the reductant in the selective generation of either C60•- or C602- is described. The electron transfer reduction of C60 by Q2- occurs via stepwise electron transfer from the Q2- to C60 in acetonitrile or benzonitrile. The C602- thus generated is used as the starting material in the synthesis of RxC60 (where x = 2 for R = C6H5CH2 and x = 1 for R = o-xylyl) by the reaction of C602- with benzyl bromide or α,α‘-dibromo-o-xylene. Theoretical calculations predict that the 1,4-isomer of (C6H5CH2)2C60 should be selectively formed, and this is confirmed by single-crystal X-ray diffraction studies. UV−visible and near-IR spectroscopy were used to monitor the progress of electron transfer from the Q2- to C60 as well as the subsequent reactions between C602- and the alkyl bromides. The comparison of the observed rate constants of the reactions of C602- with those of electron transfer from tetramethylsemiquinone radical anion to the same alkyl bromide indicates that the formation of RxC60 proceeds via the rate-determining electron transfer from C602- to the alkyl bromide.
Formation of Pseudoisocyanine J-Aggregates in Poly(vinyl alcohol) Fibers by Electrospinning (2009)

Submicrometer diameter, light emitting fibers of poly(vinyl alcohol) (PVA) doped with pseudoisocyanine (1,1'-diethyl-2,2'-cyanine bromide, PIC) dye were prepared by electrospinning. A horizontal setup was employed with a stationary collector consisting of two parallel-positioned metal strips separated by a void gap. Formation of uniaxially aligned and randomly deposited fibers in electrospun films was confirmed by microscopy. Photoluminescence (PL) spectroscopy is used to evaluate spectral properties of both types of fibers doped with PIC. While PIC molecules were individually dispersed in PVA solution, they assemble into J-aggregates upon electrospinning when the weight fraction of PIC molecules is above 2.5 wt %. The formation of J-aggregates was observed in both randomly deposited and uniaxially aligned electrospun fibers. Moreover, the fibers aligned uniaxially showed a high degree of polarized emission (PLparallel/PLperpendicular=10), arising from the orientation of J-aggregates along the fiber axis. On the other hand, isotropic emission of J-aggregates was observed from the fibers deposited randomly. As a conclusion, electrospinning was found to be an efficient and a practical method to form highly oriented J-aggregates dispersed into polymer fibers. To the best of our knowledge, it is the first time formation of J-aggregates (a bottom-up approach) and electrospinning (a top-down approach) is successfully combined.
Low-Threshold Organic Lasers Based on Single-Crystalline Microribbons of Aggregation-Induced Emission Luminogens (2019)

Solid-state lasers (SSLs) play an important role in developing optoelectronic devices, optical communication, and modern medicine fields. As compared with inorganic SSLs, the electrically pumped organic SSLs (OSSLs) still remain unrealized because of the high lasing threshold and low carrier mobility. Herein, we first demonstrate the laser action at ∼520 nm based on the self-assembled single-crystalline organic microribbons of the aggregation-induced emission (AIE) molecules of 1,4-bis(( E)-4-(1,2,2-triphenylvinyl)styryl)-2,5-dimethoxybenzene (TPDSB). Moreover, these as-prepared organic microribbons exhibit an effective optical waveguide with a low optical loss of 0.012 dB μm<sup>-1</sup>, indicating good light confinement for laser resonator feedback. Impressively, the multiple mode and the single mode lasing are both achieved from individual organic microribbons, whose lasing threshold is as low as 653 nJ cm<sup>-2</sup>. These "bottom-up" synthesized organic microribbons based on AIE-active molecules offer a new strategy for the realization of the ultralow threshold OSSLs, which would eventually contribute to the realization of electrically pumped OSSLs.
Flow cytometric quantitative determination of ingestion by phagocytes needs the distinguishing of overlapping populations of binding and ingesting cells (2005)

Essential elements of the present method appeared to be partial quenching of extracellular fluorescence with trypan blue and distinguishing between overlapping populations of binding and ingesting cells. Corrections using derived phagocytotic equations proved necessary for accurate kinetic phagocytotic measurements. Corrections were less necessary when the ingestion process was finished.

Cylindrical Superparticles from Semiconductor Nanorods (2009)

In this communication, we report a synthesis of anisotropic colloidal superparticles (SPs) from CdSe/CdS semiconductor nanorods. These anisotropic SPs are cylindrical disks or stacked-disk arrays. We attribute the major driving forces controlling the SP shape to interparticle interactions between nanorods and solvophobic interactions between a superparticle and its surrounding solvent. According to their sizes (or volumes), the SPs adopt either single- or multilayered structures. In addition, these SPs exhibit linearly polarized emissions, demonstrating their potential role as useful components in devices such as polarized light-emitting diodes and electrooptical modulators.
Scattering of sound by a vorticity filament: An experimental and numerical investigation (2001)

A vorticity filament is investigated experimentally using the transmission of an ultrasonic wave through the flow. The analysis of the wave-front distortion provides noninvasive measurements of the vortex circulation and size. The latter is estimated by analytical calculations of the scattering of a plane wave by a vorticity filament. The case of a cylindrical wave incident on a vortex leads to similar experimental results which are successfully compared to a parabolic equation simulation. Finally, a finite-difference code based on linear acoustics is presented, in order to investigate the structure of the scattered wave numerically.
A review of melatonin as a suitable antioxidant against myocardial ischemia–reperfusion injury and clinical heart diseases (2014)

Cardiac tissue loss is one of the most important factors leading to the unsatisfactory recovery even after treatment of ischemic heart disease. Melatonin, a circadian molecule with marked antioxidant properties, protects against ischemia-reperfusion (IR) injury. In particular, the myocardial protection of melatonin is substantial. We initially focus on the cardioprotective effects of melatonin in myocardial IR. These studies showed how melatonin preserves the microstructure of the cardiomyocyte and reduces myocardial IR injury. Thereafter, downstream signaling pathways of melatonin were summarized including Janus kinase 2/signal transducers and activators of transcription 3, nitric oxide-synthase, and nuclear factor erythroid 2 related factor 2. Herein, we propose the clinical applications of melatonin in several ischemic heart diseases. Collectively, the information summarized in this review (based on in vitro, animal, and human studies) should serve as a comprehensive reference for the action of melatonin in cardioprotection and hopefully will contribute to the design of future experimental research.
Lumiscope Lens-Screen System for Color Television (1972)

A very high-gain screen for rear projection is described. The screen makes possible the use of low-wattage projectors to provide adequate intensity for color television production. The “hot-spot” which usually appears at the center of the background-projection screen has been eliminated, making it possible to achieve high-quality color reproduction. In manufacture, a large-scale Fresnel lens is cut into a sheet of acrylic plastic. Screens as large as 76 × 102 in (193 × 260 cm) are presently available.
