On the day-to-day variation of the equatorial electrojet during quiet periods  

NASA Astrophysics Data System (ADS)

It has been known for a long time that the equatorial electrojet varies from day to day even when solar and geomagnetic activities are very low. The quiet time day-to-day variation is considered to be due to irregular variability of the neutral wind, but little is known about how variable winds drive the electrojet variability. We employ a numerical model introduced by Liu et al. (2013), which takes into account weather changes in the lower atmosphere and thus can reproduce ionospheric variability due to forcing from below. The simulation is run for May and June 2009. Constant solar and magnetospheric energy inputs are used so that day-to-day changes will arise only from lower atmospheric forcing. The simulated electrojet current shows day-to-day variability of ±25%, which produces day-to-day variations in ground level geomagnetic perturbations near the magnetic equator. The current system associated with the day-to-day variation of the equatorial electrojet is traced based on a covariance analysis. The current pattern reveals return flow at both sides of the electrojet, in agreement with those inferred from ground-based magnetometer data in previous studies. The day-to-day variation in the electrojet current is compared with those in the neutral wind at various altitudes, latitudes, and longitudes. It is found that the electrojet variability is dominated by the zonal wind at 100-120 km altitudes near the magnetic equator. These results suggest that the response of the zonal polarization electric field to variable zonal winds is the main source of the day-to-day variation of the equatorial electrojet during quiet periods.

Atmospheric angular momentum and the length of day - A common fluctuation with a period near 50 days  

NASA Technical Reports Server (NTRS)

Four astronomical measures of changes in the length of day obtained in 1979 have been shown to exhibit the same, approximately 50-day fluctuation. To find whether this fluctuation was persistent, and of meteorological origin, lunar laser ranging observations and wind data deduced from sources distributed over the globe were analyzed. A high degree of correlation was found between the two sets of data. It is implied that the 50-day period fluctuations in length of day are real and related to meteorological effects. Observed changes in length of day can provide a constraint for models for atmospheric flow, and a partial check for global analyses of such motions.

Effects of volume and periodicity on blood cultures.  

PubMed Central

Blood specimens collected for culture by using the high-volume resin-based BACTEC system over an 18-month period at the Seattle Veterans Administration Center were examined in this study. Of 7,783 cultures obtained, 624 were classified as true positives. Patients in this group had between 20 and 60 ml of blood drawn per culture and separated into 10-ml aliquots for incubation. Analysis of the results stratified by cultured volume and time interval between specimen collection accorded yield advantage to culture volume at the maximal amounts tested. No advantage was observed with any particular interval of collection. Increasing cultured volume from 20 to 40 ml increased yield by 19%. Increasing cultured volume from 40 to 60 ml increased yield by an additional 10%. The same effect was seen whether cultures were drawn simultaneously or serially within 24 h. These observations support other reports demonstrating increased yield with increased cultured blood volume. However, they demonstrate increases in yield at volumes much higher than previously considered. In conclusion, this study demonstrates that high-volume blood cultures drawn serially or simultaneously return the best yields. PMID:7852579

Continuous Glucose Monitoring in the Subcutaneous Tissue over a 14-Day Sensor Wear Period  

PubMed Central

Background Glucose monitoring systems using subcutaneously inserted sensors are currently labeled for up to 7 days of wear. In this study, we evaluated the feasibility of a 14-day wear duration using a modified version of the sensor found in the Freestyle Navigator™ continuous glucose monitoring system. Methods Sixty-two subjects with diabetes were enrolled in the study. One sensor per subject was inserted on the arm for a wear time of 14 days. Two different calibration algorithms were applied retrospectively, one that uses periodic sensor recalibrations and one without recalibrations. Sensor in vivo stability was determined by least square regression analysis using capillary blood glucose. Mean absolute relative difference (MARD) and mean relative difference were calculated. Consensus error grid analysis was performed by day and over the 14-day wear period to evaluate accuracy of both systems. The sensor insertion sites were inspected after sensor removal for skin reactions. Results Sensor data from 55 subjects were used for the analysis. The accuracy metrics for the system with recalibration were calculated to MARD = 13.9% and 84.0% in zone A (error grid analysis). The system without recalibration performed significantly better, resulting in MARD of 12.2% and 88.0% in zone A (p < .0001). The maximum change of in vivo sensor sensitivity over the 14-day wear period was 2% per day. Two subjects reported pain during the first 5 days of sensor wear, and 1 subject reported itching at the sensor site. No further skin reactions were noticed. Conclusions The study shows that a 14-day sensor wear period is achievable. Moreover, sensors using “wired enzyme” technology showed excellent in vivo stability, with no significant sensitivity loss over the 14-day wear period. PMID:24124948

Long-Period Cultural Noise: The Panama Canal Seiche  

NASA Astrophysics Data System (ADS)

Traditionally, the spectral composition of human generated or “cultural” seismic noise is dominated by short-period (SP) energy (<1s). In this study, we present evidence for long-period (LP) cultural noise (100-200s) at the USGS Global Seismographic Network (GSN) station CU.BCIP, located at the Smithsonian Tropical Research Institute (STRI) on Barro Colorado Island (BCI) in the Panama Canal. The LP seismic energy has a strong diurnal signal, with highest power during the daytime when traffic through the Panama Canal is the heaviest, ~1 ship every 10 minutes. The lowest power occurs during the late-night/early-morning hours, when container ship traffic slows to ~1 ship every hour. Spectral power observations are corroborated with data recorded by a water-level meter located approximately 80m from the seismic station, indicating that water waves are the primary source of the LP seismic signal. We show that the observed water waves are a “seiche” induced by the wakes of container ship traffic in the canal. As passing ships disturb the water surface, standing waves are induced by the summation of propagating waves, traveling in opposite directions, due to reflections off the opposite shorelines of the Panama Canal. Vertical harmonic motion results as gravity seeks to restore the horizontal surface of the body of water to a state of hydrostatic equilibrium. The longest natural-period of a seiche in an enclosed body of water is a function of basin depth and length and can be computed by a common oceanographic relationship, known as the Merian formula. For a reasonable range of Panama Canal dimensions in the vicinity of BCI, (depths from 15 to 30m and lengths from 700 to 1500m), the predicted dominant period of a seiche is between 100-200s, consistent with our seismic spectral power observations. Small rhythmic seiches are always present in disturbed enclosed bodies of water and are most often caused by either meteorological effects (wind and atmospheric pressure variations), and/or seismic activity (earthquakes, tsunamis). Historical accounts of anomalously large seiches in enclosed bodies of water such as harbors (Galveston, TX), lakes (Great Lakes, Lake Baikal), and inland seas (Adriatic Sea, Baltic Sea, North Sea) demonstrate the existence of significant flooding hazard to adjacent coastal communities. We present a possible new passive-seismic method for seiche monitoring.

The 155-day solar period in the sixteenth century and later  

NASA Technical Reports Server (NTRS)

Recent interest in short solar periods has been stimulated by the discovery of a peak period of about 150-160 days in very energetic solar flares and hard X-ray flares. Auroral data are used here as a proxy for solar activity to show the presence of the peak in data from 1570 to 1573 and in some other time periods. The data are also used to show the absence or lack of prominence of this peak at other times in the nineteenth and early twentieth centuries.

Optical Monitoring of BL Lacertae Object OJ 287: a 40-Day Period?  

E-print Network

We present the results of our optical monitoring of the BL Lacertae object OJ 287 during the first half of 2005. The source did not show large-amplitude variations during this period and was in a relatively quiescent state. A possible period of 40 days was derived from its light curves in three BATC wavebands. A bluer-when-brighter chromatism was discovered, which is different from the extremely stable color during the outburst in 1994--96. The different color behaviors imply different variation mechanisms in the two states. We then re-visited the optical data on OJ 287 from the OJ-94 project and found as well a probable period of 40 days in its optical variability during the late-1994 outburst. The results suggest that two components contribute to the variability of OJ 287 during its outburst state. The first component is the normal {\\sl blazar} variation. This component has an amplitude similar to that of the quiescent state and also may share a similar periodicity. The second component can be taken as a `low-frequency modulation' to the first component. It may be induced by the interaction of the assumed binary black holes in the center of this object. The 40-day period may be related to the helical structure of the magnetic field at the base of the jet, or to the orbital motion close to the central primary black hole.

The power spectrum of the solar wind speed for periods greater than 10 days  

NASA Technical Reports Server (NTRS)

The use of the more than 11 years of solar wind speed data obtained by Vela 2-6 and Imp 6-8 to study the power spectrum of speed variations in the range near the solar rotational frequency is discussed. The broad bands of power near periods of 27 days (corresponding to the rotational period of the sun), 13.5 days, and higher harmonics are characterized, and it is suggested that the described individual peaks in both the solar wind and the geomagnetic spectra are probably not due to differential rotation. The alternate explanation is that the multipeak nature of the power spectra are explained by a wave packet concept in which recurring highspeed streams are described as a series of pulses (separated by a constant period) that last for a varying number of solar rotations.

Regulation of period 1 expression in cultured rat pineal  

NASA Technical Reports Server (NTRS)

The aim of the present study was to investigate the in vitro expression of Period 1 (Per1), Period 2 (Per2) and arylalkylamine N-acetyltransferase (AA-NAT) genes in the rat pineal gland to understand the mechanism(s) regulating the expression of these genes in this organ. Pineals, when maintained in vitro for 5 days, did not show circadian rhythmicity in the expression of any of the three genes monitored. Norepinephrine (NE) induced AA-NAT and Per1, whereas its effect on Per2 was negligible. Contrary to what was observed in other systems, NE stimulation did not induce circadian expression of Per1. The effect of NE on Per1 level was dose- and receptor subtype-dependent, and both cAMP and cGMP induced Per1. Per1 was not induced by repeated NE - or forskolin - stimulation. Protein synthesis was not necessary for NE-induced Per1, but it was for reduction of Per1 following NE stimulation. Per1 transcription in pinealocytes was activated by BMAL1/CLOCK. Our results indicate that important differences are present in the regulation of these genes in the mammalian pineal. Copyright 2002 S. Karger AG, Basel.

Study of 23 day periodicity of Blazar Mkn501 in 1997  

E-print Network

We confirm a 23 day periodicity during a large flare in 1997 for X-ray data of X-ray satellite RXTE all sky monitor(ASM), 2 TeV gamma ray data from Utah Seven Telescope and HEGRA, with a Fourier analysis. We found the three results to be the same with a newly estimated error. We confirm the presence of a frequency dependent power (1/f noise) in a frequency-power diagram. Further, we calculated a chance probability of the occurrence of the 23 day periodicity by considering the 1/f noise and obtained a chance probability 4.88*10^-3 for the HEGRA data: this is more significant than previous result by an order. We also obtained an identical peridoicity with another kind of timing analysis-epoch folding method for the ASM data and HEGRA data. We strongly suggest an existence of the periodicity. We divided the HEGRA data into two data sets, analyzed them with a Fourier method, and found an unstableness of the periodicity with a 3.4 sigma significance. We also analyzed an energy spectra of the X-ray data of a RXTE proportional counter array and we found that a combination of three parameters-a magnetic field, a Lorentz factor, and a beaming factor-is related to the periodicity.

Growth of mallards fed phosphamidon for 13-day periods during three different developmental stages  

USGS Publications Warehouse

Mallard ducklings (Anas platyrhynchos) were exposed to a 13-day dietary treatment of O, 0.5, or 5.0 ppm phosphamidon at one of three successive age intervals (5-17 days, 18-30 days, or 31-43 days) during a 10-week growth period. Weekly measurements of body weight, wing length, primary feather length, and bill length revealed slower development of primary feathers in those birds treated from 5 to 17 days; treatment effects on body weight and wing length from 6 to 8 weeks of age were observed among those birds treated from 18 to 30 days of age. Some differences in growth patterns among birds treated with the same phosphamidon level, but at different growth stages, were attributed to the varying size of the group with which a duckling was housed at different times in the growth process. No brain cholinesterase depression was observed in any group either 24 h after phosphamidon treatment was terminated or at 10 weeks of age.

WASP-117b: a 10-day-period Saturn in an eccentric and misaligned orbit  

NASA Astrophysics Data System (ADS)

We report the discovery of WASP-117b, the first planet with a period beyond 10 days found by the WASP survey. The planet has a mass of Mp = 0.2755 ± 0.0089 MJ, a radius of Rp= 1.021_{-0.065+0.076 Rjup} and is in an eccentric (e = 0.302 ± 0.023), 10.02165 ± 0.00055 d orbit around a main-sequence F9 star. The host star's brightness (V = 10.15 mag) makes WASP-117 a good target for follow-up observations, and with a periastron planetary equilibrium temperature of Teq= 1225_{-39+36} K and a low planetary mean density (?p= 0.259_{-0.048+0.054 ?jup}) it is one of the best targets for transmission spectroscopy among planets with periods around 10 days. From a measurement of the Rossiter-McLaughlin effect, we infer a projected angle between the planetary orbit and stellar spin axes of ? = -44 ± 11 deg, and we further derive an orbital obliquity of ? = 69.6 +4.7-4.1 deg. Owing to the large orbital separation, tidal forces causing orbital circularization and realignment of the planetary orbit with the stellar plane are weak, having had little impact on the planetary orbit over the system lifetime. WASP-117b joins a small sample of transiting giant planets with well characterized orbits at periods above 8 days. Based on data obtained with WASP-South, CORALIE and EulerCam at the Euler-Swiss telescope, TRAPPIST, and HARPS at the ESO 3.6 m telescope (Prog.

A seven day running training period increases basal urinary hepcidin levels as compared to cycling  

PubMed Central

Background This investigation compared the effects of an extended period of weight-bearing (running) vs. non-weight-bearing (cycling) exercise on hepcidin production and its implications for iron status. Methods Ten active males performed two separate exercise training blocks with either running (RTB) or cycling (CTB) as the exercise mode. Each block consisted of five training sessions (Day 1, 2, 4, 5, 6) performed over a seven day period that were matched for exercise intensity. Basal venous blood samples were obtained on Day 1 (D1), and on Recovery Days 3 (R3) and 7 (R7) to assess iron status, while basal and 3 h post-exercise urinary hepcidin levels were measured on D1, D2, D6, as well as R3 and R7 (basal levels only) for each condition. Results Basal urinary hepcidin levels were significantly elevated (p???0.05) at D2, R3 and R7 as compared to D1 in RTB. Furthermore, 3 h post-exercise urinary hepcidin levels on D1 were also significantly higher in RTB compared to CTB (p???0.05). In CTB, urinary hepcidin levels were not statistically different on D1 as compared to R7. Iron parameters were not significantly different at D1 compared to R3 and R7 during both conditions. Conclusions These results suggest that basal hepcidin levels may increase over the course of an extended training program, especially if a weight-bearing exercise modality is undertaken. However, despite any variations in hepcidin production, serum iron parameters in both RTB and CTB were unaffected, possibly due to the short duration of each training block. In comparing running to cycling, non-weight-bearing activity may require more training sessions, or sessions of extended duration, before any significant changes in basal hepcidin levels appear. Chronic elevations in hepcidin levels may help to explain the high incidence of iron deficiency in athletes. PMID:24716892

Erratum: The 2.27 day period of WR-134 (HD 191765)  

NASA Astrophysics Data System (ADS)

The original temporal analysis of a 12 night spectral timeseries of Wolf-Rayet (WR)-134 has been found to be flawed and a re-analysis shows that the line profile variations are indeed periodic. When combined with a 4 night timeseries taken 45 days earlier, a period near 2.27 d is found in periodograms of the He II lambda 5412 line centroid, rms line width, and line skew variations. When the emission line residuals are ordered as a function of phase, a sinuous feature appears to 'snake' about the line center with an amplitude of +/-500 km/s. This is approximately equal to 20 larger than the line centroid amplitude; the calculation of which is heavily weighted by static portions of the line profile. In addition to the 'snake,' emission residuals appear that move away from line center on unbound trajectories and are thought to result from the interaction of a periodic driver with the unstable flow of the radiation driven wind.

Effect of end-of-day irradiations on polyamine accumulation in petal cultures of Araujia sericifera.  

PubMed

We have studied photoperiodic control and the effect of phytochrome photoconversion at the end-of-day (EOD) on polyamine (PA) accumulation in petal explants of Araujia sericifera. Petals from immature flowers were cultured under long (LD) and short (SD) days. Light was provided by Gro-lux fluorescent lamps (90-100 &mgr;mol m-2 s-1). Red (R), far red (FR), red followed by far-red (R-FR) and far-red followed by red (FR-R) light treatments were applied daily at the end of the photoperiod. The free and bound putrescine (Put), spermidine (Spd) and spermine (Spm) fractions in petal explants were determined 40 days after the beginning of the culture. We also aimed to clarify the involvement of PA changes by using two inhibitors of PA biosynthesis: D-l-alpha-difluoromethylarginine (DFMA) and methylglyoxal bis(guanylhydrazone) (MGBG). We found PA accumulation to be under photoperiodic control, and the inhibitory effect of DFMA on this accumulation suggests that arginine decarboxylase (ADC) is the major pathway for Put biosynthesis. Polyamine levels were higher under LD, mainly as a result of the accumulation of free and bound Put. FR-EOD treatment, which dramatically reduced the R : FR ratio after LD, increased the accumulation of PA, mainly as free Put and free and bound Spd. Sequential R-FR and FR-R-EOD treatments strongly increased bound Spd. The concentration of MGBG used increased total PA accumulation, mainly as Put. However, all EOD light treatments dramatically reduced Put accumulation in the presence of MGBG. This may be due to a dual role of FR light in PA accumulation: (1) FR per se stimulates PA production, probably via ADC, and (2) in the presence of MGBG, FR inhibits Put accumulation, probably via ethylene production.

Discovery of a 115 Day Orbital Period in the Ultraluminous X-ray Source NGC 5408 X-1  

NASA Technical Reports Server (NTRS)

We report the detection of a 115 day periodicity in SWIFT/XRT monitoring data from the ultraluminous X-ray source (ULX) NGC 5408 X-1. Our o ngoing campaign samples its X-ray flux approximately twice weekly and has now achieved a temporal baseline of ti 485 days. Periodogram ana lysis reveals a significant periodicity with a period of 115.5 +/- 4 days. The modulation is detected with a significance of 3.2 x 10(exp -4) . The fractional modulation amplitude decreases with increasing e nergy, ranging from 0.13 +/- 0.02 above 1 keV to 0.24 +/- 0.02 below 1 keV. The shape of the profile evolves as well, becoming less sharply peaked at higher energies. The periodogram analysis is consistent wi th a periodic process, however, continued monitoring is required to c onfirm the coherent nature of the modulation. Spectral analysis indic ates that NGC 5408 X-1 can reach 0.3 - 10 keV luminosities of approxi mately 2 x 10 40 ergs/s . We suggest that, like the 62 day period of the ULX in M82 (X41.4-1-60), the periodicity detected in NGC 5408 X-1 represents the orbital period of the black hole binary containing the ULX. If this is true then the secondary can only be a giant or super giant star.

a 1.4 Day Period in RX J0050.7-7316 - AN Unusual HMXB in the SMC  

NASA Astrophysics Data System (ADS)

Cook et al. identified a 0.7 day period in the Be star optical counterpart of the SMC X-ray pulsar RX J0050.7-7316. Further observations and analysis by Coe & Orosz suggest that the orbital period may in fact be twice this at 1.4 days. Either of these periods would be extremely short for a Be/neutron star system, while the 323 s pulse period is rather long. We propose here to investigate this mystery by performing RXTE observations which cover a complete binary period and so undertake a study of orbital Doppler shifts. The observations should reveal the mass function of the object and may enable the detection of an eclipse, key parameters in understanding the astrophysics of the system.

Coccidiosis control by administering toltrazuril in the drinking water for a 2-day period.  

PubMed

A 56-day floor pen study was conducted to determine the appropriate time to administer toltrazuril (Baycox) (TOL) for control of coccidiosis in broiler chickens. Litter was seeded with field strains of Eimeria acervulina, Eimeria maxima and Eimeria tenella. On Days 0, 21, 35 and 56, all birds and feed were weighed. Starting on Day 14, weekly lesion scores and oocyst counts were performed. The treatments were 125 ppm nicarb (NIC) in the starter to 66 ppm salinomycin (SAL) in the grower with no TOL (NIC/SAL/no TOL), 66 ppm salinomycin in both the starter and the grower but no TOL (SAL/SAL/no TOL), or no in-feed medication with the following TOL treatment: TOL Days 2-3, TOL Days 6-7, TOL Days 10-11, TOL Days 14-15, TOL Days 18-19, and as control NM/NM/no TOL (NM). The withdrawal feed was nonmedicated. TOL was administered in the drinking water at the rate of 7 mg/kg body weight. Oocysts per gram litter and lesion scores showed a significant infection in the NM birds, which peaked about Day 21. The NIC/SAL gave excellent early protection but only moderate protection during the SAL phase. The final performance for the SAL/SAL was significantly less compared to all TOL and NIC/SAL birds. All TOL treatments but Days 2-3 provided good coccidiosis control with accompanying performance. The absence of clinical coccidiosis relapse during the last third of the growout along with moderate oocyst counts and low lesions was indicative of unimpaired coccidiosis immunity. It can be inferred from the overall results that the use of TOL as the sole anticoccidial for two consecutive days in the drinking water between Days 10 and 14 would be the best time for good coccidiosis control allowing full performance.

The Evolution of Cloud Features on Neptune over a 20-day time period  

NASA Astrophysics Data System (ADS)

Near-infrared images of Neptune were taken with SCAM, the slit-viewing camera of the AO/NIRSPEC system at the 10-m W.M. Keck II telescope, on 2000 June 8,17,18,22,23 and 29 UT. Observations with broad-band filter Nirspec-5 [1.61 micron], Nirspec-6 [1.93 micron], and K' [2.12 micron], and several narrow-band filters between 1.279 and 1.702 microns are compared to determine the temporal evolution of cloud features over the 20-day period. These images taken with the Keck Adaptive Optics system are spectacular, revealing narrow zonal bands at 3-4 degree latitude spacings within bright regions and near the equator. There are three regions of latitude that contain bright features along zonal bands. The dimmest of these bright regions is located in the Northern hemisphere and extends from 20 deg N to 40 deg N. The remaining two bright regions are located in the Southern hemisphere extending from 20 deg S to 50 deg S, and from 60 deg S to 70 deg S. The region near the South pole (a recently quiet location) contains a bright teardrop-shaped feature which may be related to the Westerly jet observed by Voyager and reported by Sanjay et.al. (Journal of Geophysical Research, vol.6, pp. 18941-18960, 1991) at a similar latitude. This research was supported in part by the STC Program of the National Science Foundation under Agreement No. AST-9876783, and in part under the auspices of the US Department of Energy at Lawrence Livermore National Laboratory, Univ. of Calif. under contract No. W-7405-Eng-48. Data presented herein were obtained at the W.M. Keck Observatory, which is operated as a scientific partnership among the California Institute of Technology, the University of California and the National Aeronautics and Space Administration. The Observatory was made possible by the generous financial support of the W.M. Keck Foundation.

One-day workflow scheme for bacterial pathogen detection and antimicrobial resistance testing from blood cultures.  

PubMed

Bloodstream infections are associated with high mortality rates because of the probable manifestation of sepsis, severe sepsis and septic shock(1). Therefore, rapid administration of adequate antibiotic therapy is of foremost importance in the treatment of bloodstream infections. The critical element in this process is timing, heavily dependent on the results of bacterial identification and antibiotic susceptibility testing. Both of these parameters are routinely obtained by culture-based testing, which is time-consuming and takes on average 24-48 hours(2, 4). The aim of the study was to develop DNA-based assays for rapid identification of bloodstream infections, as well as rapid antimicrobial susceptibility testing. The first assay is a eubacterial 16S rDNA-based real-time PCR assay complemented with species- or genus-specific probes(5). Using these probes, Gram-negative bacteria including Pseudomonas spp., Pseudomonas aeruginosa and Escherichia coli as well as Gram-positive bacteria including Staphylococcus spp., Staphylococcus aureus, Enterococcus spp., Streptococcus spp., and Streptococcus pneumoniae could be distinguished. Using this multiprobe assay, a first identification of the causative micro-organism was given after 2 h. Secondly, we developed a semi-molecular assay for antibiotic susceptibility testing of S. aureus, Enterococcus spp. and (facultative) aerobe Gram-negative rods(6). This assay was based on a study in which PCR was used to measure the growth of bacteria(7). Bacteria harvested directly from blood cultures are incubated for 6 h with a selection of antibiotics, and following a Sybr Green-based real-time PCR assay determines inhibition of growth. The combination of these two methods could direct the choice of a suitable antibiotic therapy on the same day (Figure 1). In conclusion, molecular analysis of both identification and antibiotic susceptibility offers a faster alternative for pathogen detection and could improve the diagnosis of bloodstream infections.

Finding a 24 Day Orbital Period for the X-Ray Binary 1A 1118-616  

NASA Technical Reports Server (NTRS)

We report the first determination of the binary period and the orbital ephemeris of the Be X-ray binary containing the pulsar IA 1118-616 (35 years after the discovery of the source). The orbital period is found to be P(sub orb) = 24.0+/-0.4 days. The source was observed by RXTE during its last big X-ray outburst in January 2009, peaking at MJD 54845.4. This outburst was sampled by taking short observations every few days, covering an elapsed time comparable to the orbital period. Using the phase connection technique, pulse arrival time delays could be measured and an orbital solution determined. The data are consistent with a circular orbit, the time of 90 degrees longitude was found to be T,/2 = MJD 54845.37(10), coincident with the peak X-ray flux.

The 54-day orbital period of AX J1820.5-1434 unveiled by Swift  

NASA Astrophysics Data System (ADS)

Context. The hard X-ray survey that Swift Burst Alert Telescope (BAT) has been performing since late 2004 provides a considerable database for a large number of sources, whose hard X-ray emission are poorly known. Aims: We exploit the BAT survey archive to improve the temporal and spectral characterization of the Galactic hard-X-ray sources. We focus here on the study of the high mass X-ray binary AX J1820.5-1434. Methods: All the data relevant to AX J1820.5-1434 were extracted from the BAT survey archive and analyzed using a folding technique to search for periodical modulations. A broad-band spectral analysis was also performed, complementing the BAT spectrum with the available Swift X-Ray Telescope (XRT) and XMM-Newton pointed observations. Results: A timing analysis revealed the detection of a coherent signal at P0 = 54.0 ± 0.4 d, which we interpret as the orbital period of the binary system. When folded with a period of P0, the light curve shows an asymmetric profile with a minimum roughly consistent with zero intensity. The broadband spectral analysis coupling Swift-XRT, XMM-Newton, and Swift-BAT spectra confirms that the source emission is well modeled with a strongly absorbed power law with no evidence of a high energy exponential cutoff.

The role of 3D microenvironmental organization in MCF-7 epithelial–mesenchymal transition after 7 culture days  

SciTech Connect

We present a multi-technique study on in vitro epithelial–mesenchymal transition (EMT) in human MCF-7 cells cultured on electrospun scaffolds of poly(L-lactic acid) (PLA), with random and aligned fiber orientations. Our aim is to investigate the morphological and genetic characteristics induced by extracellular matrix in tumor cells cultured in different 3D environments, and at different time points. Cell vitality was assessed with AlamarBlue at days 1, 3, 5 and 7. Scanning electron microscopy was performed at culture days 3 and 7. Immunohistochemistry (for E-cadherin, ?-catenin, cytokeratins, nucleophosmin, tubulin, Ki-67 and vimentin), immunofluorescence (for F-actin) western blot (for E-cadherin, ?-catenin and vimentin) and transmission electron microscopy were carried out at day 7. An EMT gene array followed by PCR analysis confirmed the regulation of selected genes. At day 7, scanning electron microscopy on aligned-PLA revealed spindle-shaped cells gathered in buds and ribbon-like structures, with a higher nucleolar/nuclear ratio and a loss in E-cadherin and ?-catenin at immunohistochemistry and western blot. An up-regulation of SMAD2, TGF-?2, TFPI2 and SOX10 was found in aligned-PLA compared to random-PLA cultured cells. The topography of the extracellular matrix has a role in tumor EMT, and a more aggressive phenotype characterizes MCF-7 cells cultured on aligned-PLA scaffold. -- Highlights: • After 7 culture days an aligned-PLA scaffold induces a spindle shape to MCF-7 cells. • Despite these changes, the aligned MCF-7 cells keep an epithelial phenotype. • The extracellular environment alone influences the E-cadherin/?-catenin axis. • The extracellular environment can promote the epithelial–mesenchymal transition.

+Gz tolerance in man after 14-day bedrest periods with isometric and isotonic exercise conditioning  

NASA Technical Reports Server (NTRS)

The effects of isometric and isotonic exercise training on post-bedrest +Gz tolerance were determined. In general, 14-day bedrest resulted in a significant loss of Gz tolerance, as previously discovered. At 2.1 Gz, neither the isometric nor the isotonic exercises regimens resulted in a significant increase in post-bedrest Gz tolerance. However, following isometric exercise, restoration of about half the tolerance decrement occurred at 3.2 Gz and 3.8 Gz. Possible reasons for this partial restoration of tolerance are put forward.

A 154-day periodicity in the occurrence of hard solar flares?  

NASA Technical Reports Server (NTRS)

An analysis of the temporal distribution of 139 solar flares monitored by the Gamma Ray Spectrometer aboard the Solar Maximum Mission is reported. It is found that, instead of being randomly distributed in time, these events have a tendency to occur in groups with a mean spacing of about 154 days (75 nHz) over the observing interval. A larger sample of flares with an X-ray classification of M 2.5 or larger recorded by the GOES satellite showed a similar regularity.

ICSI and day 5 embryo transfers: higher implantation rates and lower rate of multiple pregnancy with prolonged culture.  

PubMed

This retrospective review study, carried out in a private IVF clinic, compared pregnancy and implantation rates with day 3 versus day 5 embryo transfers in a selected group of patients. Participants were patients who failed to achieve pregnancy in at least one previous attempt with embryo transfer on days 2 or 3, and had more than five oocytes fertilized. A total of 296 patients who had undergone day 3 (group A) transfers were compared with 154 who had undergone day 5 transfers (group B). Interventions were intracytoplasmic sperm injection (ICSI), day 3 and day 5 embryo transfer. Outcome measures were pregnancy, implantation, multiple gestation and blastocyst formation rates. Overall, 86.4% of embryos were at the six- to eight-cell stage at 72 h and 30% developed to blastocyst by day 5. The mean number of embryos transferred was 4.0 on day 3 and 3.0 on day 5. Pregnancy and implantation rates were 34.8 and 11.5% in group A, versus 45.3 and 18.5% in group B. Multiple gestation rate was 47.1% in group A and 28.5% in group B. Prolonging embryo culture in vitro to day 5 improved embryo selection and implantation rates. A significant decrease in high order gestations was achieved by reducing the number of embryos transferred, without compromising the pregnancy rates. PMID:12513858

The response of middle atmospheric ozone to solar UV irradiance variations with a period of 27 days  

NASA Technical Reports Server (NTRS)

A one-dimensional photochemical-dynamical-radiative time-dependent model was used to study the response of middle atmospheric temperature and ozone to solar UV irradiance variations with the period of 27 days. The model solar UV O(x), HO(x), NO(x), and CIO(x)families and modeled solar UV variations. The amplitude of the primary temperature response to the solar UV variation is plus 0.4 K at 85-90 km with a phase lag of about 6 days. A secondary maximum response of plus 0.3 K at 45-50 km appears with a phase lag of 1 day. There is a maximum positive ozone response to the 27-day solar UV oscillation of 2.5 percent at 80-90 km with a phase lag of about 10 days after the solar irradiance maximum. At 70 km the ozone response is about 1.2 percent and is out of phase with the solar variation. In the upper stratosphere (40-50 km) the relative ozone variation is small, about 0.2 percent to 0.3 percent, and there is a negative phase of about 4 days between the ozone and solar oscillations. These oscillations are in phase in the middle stratosphere (35-40 km) where there is again a maximum relative response of about 0.6 percent. The reasons for these ozone amplitude and phase variations are discussed.

Electromagnetic induction in the oceans and the anomalous behaviour of coastal C-responses for periods up to 20 days  

NASA Astrophysics Data System (ADS)

Electromagnetic transfer functions at coastal sites are known to be strongly distorted by the conductivity of the seawater. This ocean effect is generally considered to be small for periods greater than a few days. We revise this statement by detailed and systematic model studies in the period range from 1 to 64 days, with subsequent comparison of the modelled and observed electromagnetic responses. The conductivity model consists of a radial symmetric (1-D) section that is overlaid by a thin spherical surface shell, the conductance of which is compiled using the NOAA ETOPO topography/bathymetry and map of sediment thicknesses. The simulations were performed for spatial resolutions of the surface shell of 5° × 5°, 2° × 2° and 1° × 1°, respectively, and for two, continental and oceanic, underlying 1-D conductivity models. The inducing source is described by the spherical harmonic P10 in dipole coordinates. Comparisons are made for the coastal geomagnetic observatories Apia, Hermanus, Kakioka, Kanoya, and Simosato where an anomalous behaviour of the local response has been previously detected. From the comparison of observed and modelled responses we conclude that peculiarities in the observed coastal responses in the period range from 1 to 20 days can be explained to a large amount by induction in the oceans. We show that correction for the ocean effect results in responses that are much better interpretable by 1-D conductivity models compared to the uncorrected responses.

Effect of dark/light periods on the polyhydroxyalkanoate production of a photosynthetic mixed culture.  

PubMed

This work studied the possibility of operating a viable polyhydroxyalkanoate (PHA) producing photosynthetic mixed culture (PMC) under dark/light periods without aeration. The culture was subjected to a feast and famine regime, being fed in the dark phase and entering into famine during the light phase. Throughout consecutive feast and famine dark/light periods, the PMC became enriched in PHA accumulating organisms, where non-PHA producing algae that can grow under continuous illumination were out-competed. The very low algae levels enabled greater light and carbon source availability for PHA accumulating bacteria, leading to higher metabolic rates and PHA levels. The PMC reached a PHA content of 30% PHA/VSS, and doubled its specific PHA production rate in relation to PMCs operated previously under continuous illumination. This new process takes a further step towards operating a more cost effective PMC system for PHA production, opening up the possibility for direct sunlight utilization in the future. PMID:24077157

Factors influencing the chance of cows being pregnant 30 days after the herd voluntary waiting period.  

PubMed

The objective of this study was to study factors affecting a reproductive performance indicator at the cow level adjusted for herd management strategy. Associations between the outcome variable, pregnant or not at the herd voluntary waiting period (VWP) plus 30d (pregnant at VWP+30), and the predictor variables were analyzed using a multivariable, generalized estimation equations model that adjusted for clustering of the data at the herd level. The statistical analysis was stratified on parity. In total, 132,721 cows were retained for analyses, of which 29,113 (22%) were pregnant at VWP+30d. Of the nonpregnant cows, 81,483 cows had records of artificial inseminations (AI) and 22,125 cows had no records of AI. The chance of pregnancy was higher for cows of the Swedish Red and for other/crossbreeds compared with Swedish Holstein, for cows from herds with high heat detection efficiency compared with cows from herds with medium and low heat detection efficiency, for cows from herds with long VWP (i.e., >51d) compared with cows from herds with short VWP (<51d), and for cows in freestalls compared with cows in tiestalls. The chance for pregnancy was lower for cows with severe problems at claw trimming compared with cows with no problems at trimming (only for second- and higher-parity cows), for cows that had a record of reproduction-related disease, for cows that had a record of any other disease compared with cows without record, for second- and higher-parity cows with records of dystocia compared with cows with no record of dystocia, for first-parity cows in the group with the highest milk yield compared with first-parity cows in the group with the lowest milk yield, for cows of third and higher parity in the group with the lowest milk yield compared with cows in higher yielding groups, for cows bred in summer compared with those bred in winter-spring (not significant for first-parity cows), and for cows with a twin birth had compared with cows with a single birth. We observed associations of the dose-response type, such that when the milk fat-to-protein ratio increased, the chance for pregnancy decreased, and as the somatic cell count increased, the chance for pregnancy decreased. In conclusion, factors that are known to affect reproductive efficiency also affect the chance of cows being pregnant at the herd VWP plus 30d. PMID:24485688

Global Characteristics of the Correlation and Time Lag Between Solar and Ionospheric Parameters in the 27-day Period  

NASA Technical Reports Server (NTRS)

The 27-day variations of topside ionosphere are investigated using the in-situ electron density measurements from the CHAMP planar Langmuir probe and GRACE K-band ranging system. As the two satellite systems orbit at the altitudes of approx. 370 km and approx. 480 km, respectively, the satellite data sets are greatly valuable for examining the electron density variations in the vicinity of F2-peak. In a 27-day period, the electron density measurements from the satellites are in good agreements with the solar flux, except during the solar minimum period. The time delays are mostly 1-2 day and represent the hemispherical asymmetry. The globally-estimated spatial patterns of the correlation between solar flux and in-situ satellite measurements show poor correlations in the (magnetic) equatorial region, which are not found from the ground measurements of vertically-integrated electron content. We suggest that the most plausible cause for the poor correlation is the vertical movement of ionization due to atmospheric dynamic processes that is not controlled by the solar extreme ultraviolet radiation.

The October-November, 2003 Solar Activity and its Relationship to the "approximately 155 day" Solar Periodicity  

NASA Technical Reports Server (NTRS)

Periodicities of - 155 days in various solar and interplanetary phenomena were first discovered during solar cycle 21 and have been shown t o be intermittently present in other solar cycles. In the current solar cycle (23), they have been reported in solar energetic particle events and interplanetary coronal maSS ejections. We assess whether the "unexpected" October - November 2003 burst of solar activity during the late declining phase of the cycle may have been a manifestation of such a periodic behavior, and hence might have been to =me extent "predictable". If the pattern were to continue, episodes of enhanced activity might be expected around April - May and October, 2004. There was a mod- est increase activity increase in mid-April, 2004 which may conform to this pattern.

Objectives Competitive endurance athletes commonly undertake periods of overload training in the weeks prior to major competitions. This investigation examined the effects of two seven-day high-intensity overload training regimes (HIT) on performance and physiological characteristics of competitive cyclists. Design The study was a matched groups, controlled trial. Methods Twenty-eight male cyclists (mean ± SD, Age: 33±10 years, Mass 74±7 kg, VO2 peak 4.7±0.5 L·min?1) were assigned to a control group or one of two training groups for seven consecutive days of HIT. Before and after training cyclists completed an ergometer based incremental exercise test and a 20-km time-trial. The HIT sessions were ?120 minutes in duration and consisted of matched volumes of 5, 10 and 20 second (short) or 15, 30 and 45 second (long) maximal intensity efforts. Results Both the short and long HIT regimes led to significant (p<0.05) gains in time trial performance compared to the control group. Relative to the control group, the mean changes (±90% confidence limits) in time-trial power were 8.2%±3.8% and 10.4%±4.3% for the short and long HIT regimes respectively; corresponding increases in peak power in the incremental test were 5.5%±2.7% and 9.5%±2.5%. Both HIT (short vs long) interventions led to non-significant (p>0.05) increases (mean ± SD) in VO2 peak (2.3%±4.7% vs 3.5%±6.2%), lactate threshold power (3.6%±3.5% vs 2.9%±5.3%) and gross efficiency (3.2%±2.4% vs 5.1%±3.9%) with only small differences between HIT regimes. Conclusions Seven days of overload HIT induces substantial enhancements in time-trial performance despite non-significant increases in physiological measures with competitive cyclists. PMID:25521824

Analysis of 281,797 consecutive blood cultures performed over an eight-year period: trends in microorganisms isolated and the value of anaerobic culture of blood.  

PubMed

The results for 281,797 blood culture sets of specimens collected from adult patients at the Mayo Clinic over an approximately 8-year period (1 November 1984 through 30 November 1992) were analyzed in order to determine whether there were differences in the types of microorganisms isolated over this time and to assess the usefulness of anaerobic culturing of blood. Each blood culture set consisted of two aerobic blood cultures (Septi-Chek [Becton Dickinson, Sparks, MD] and Isolator [Wampole Laboratories, Cranbury, NJ]) and one anaerobic culture (nonvented tryptic or trypticase soy broth [NVTSB; Difco Laboratories, Detroit, or Becton Dickinson]). The relative frequency of isolation of aerobic and facultatively anaerobic gram-positive bacteria and obligately anaerobic bacteria increased over the second half of the 1984-1992 surveillance period. The value of the NVTSB anaerobic blood culture was demonstrated for diagnosing bloodstream infections caused by certain facultatively anaerobic bacteria in addition to obligately anaerobic bacteria and supported the inclusion of the NVTSB anaerobic blood culture as a standard part of the three-component blood culture set used at this institution.

Inter- and intra-individual variation in urinary biomarker concentrations over a 6-day sampling period. Part 1: Metals.  

PubMed

The aim of the current HBM-study is to further the understanding of the impact of inter- and intra-individual variability in HBM surveys as it may have implications for the design and interpretation of the study outcomes. As spot samples only provide a snapshot in time of the concentrations of chemicals in an individual, it remains unclear to what extent intra-individual variability plays a role in the overall variability of population-wide HBM surveys. The current paper describes the results of an intensive biomonitoring study, in which all individual urine samples of 8 individuals were collected over a 6-day sampling period (a total of 352 unique samples). By analyzing different metals (As, Cd, Mn, Ni) in each individual sample, inter- and intra-individual variability for these four metals could be determined, and the relationships between exposure, internal dose, and sampling protocol assessed. Although the range of biomarker values for different metals was well within the normal range reported in large-scale population surveys, large intra-individual differences over a 6-day period could also be observed. Typically, measured biomarker values span at least an order of magnitude within an individual, and more if specific exposure episodes could be identified. Fish consumption for example caused a twenty- to thirty-fold increase in urinary As-levels over a period of 2-6h. Intra-class correlation coefficients (ICC) were typically low for uncorrected biomarker values (between 0.104 and 0.460 for the 4 metals), but improved when corrected for creatinine or specific gravity (SG). The results show that even though urine is a preferred matrix for HBM studies, there are certain methodological issues that need to be taken into account in the interpretation of urinary biomarker data, related to the intrinsic variability of the urination process itself, the relationship between exposure events and biomarker quantification, and the timing of sampling. When setting up HBM-projects, this expected relationship between individual exposure episode and urinary biomarker concentration needs to be taken into account. PMID:25128590

Periodization  

PubMed Central

Background: Clinicians are constantly faced with the challenge of designing training programs for injured and noninjured athletes that maximize healing and optimize performance. Periodization is a concept of systematic progression—that is, resistance training programs that follow predictable patterns of change in training variables. The strength training literature is abundant with studies comparing periodization schemes on uninjured, trained, and untrained athletes. The rehabilitation literature, however, is scarce with information about how to optimally design resistance training programs based on periodization principles for injured athletes. The purpose of this review is to discuss relevant training variables and methods of periodization, as well as periodization program outcomes. A secondary purpose is to provide an anecdotal framework regarding implementation of periodization principles into rehabilitation programs. Evidence Acquisition: A Medline search from 1979 to 2009 was implemented with the keywords periodization, strength training, rehabilitation, endurance, power, hypertrophy, and resistance training with the Boolean term AND in all possible combinations in the English language. Each author also undertook independent hand searching of article references used in this review. Results: Based on the studies researched, periodized strength training regimens demonstrate improved outcomes as compared to nonperiodized programs. Conclusions: Despite the evidence in the strength training literature supporting periodization programs, there is a considerable lack of data in the rehabilitation literature about program design and successful implementation of periodization into rehabilitation programs.

An orbital period of 0.94 days for the hot-Jupiter planet WASP-18b.  

PubMed

The 'hot Jupiters' that abound in lists of known extrasolar planets are thought to have formed far from their host stars, but migrate inwards through interactions with the proto-planetary disk from which they were born, or by an alternative mechanism such as planet-planet scattering. The hot Jupiters closest to their parent stars, at orbital distances of only approximately 0.02 astronomical units, have strong tidal interactions, and systems such as OGLE-TR-56 have been suggested as tests of tidal dissipation theory. Here we report the discovery of planet WASP-18b with an orbital period of 0.94 days and a mass of ten Jupiter masses (10 M(Jup)), resulting in a tidal interaction an order of magnitude stronger than that of planet OGLE-TR-56b. Under the assumption that the tidal-dissipation parameter Q of the host star is of the order of 10(6), as measured for Solar System bodies and binary stars and as often applied to extrasolar planets, WASP-18b will be spiralling inwards on a timescale less than a thousandth that of the lifetime of its host star. Therefore either WASP-18 is in a rare, exceptionally short-lived state, or the tidal dissipation in this system (and possibly other hot-Jupiter systems) must be much weaker than in the Solar System.

Swift reveals a ~5.7 day super-orbital period in the M31 globular cluster X-ray binary XB158  

E-print Network

The M31 globular cluster X-ray binary XB158 (a.k.a. Bo 158) exhibits intensity dips on a 2.78 hr period in some observations, but not others. The short period suggests a low mass ratio, and an asymmetric, precessing disk due to additional tidal torques from the donor star since the disk crosses the 3:1 resonance. Previous theoretical 3D smoothed particle hydrodynamical modeling suggested a super-orbital disk precession period 29$\\pm$1 times the orbital period, i.e. $\\sim$81$\\pm$3 hr. We conducted a Swift monitoring campaign of 30 observations over ~1 month in order to search for evidence of such a super-orbital period. Fitting the 0.3--10 keV Swift XRT luminosity lightcurve with a sinusoid yielded a period of 5.65+/-0.05 days, and a >5$\\sigma$ improvement in $\\chi^2$ over the best fit constant intensity model. A Lomb-Scargle periodogram revealed that periods 5.4--5.8 days were detected at a >3$\\sigma$ level, with a peak at 5.6 days. We consider this strong evidence for a 5.65 day super-orbital period, ~70\\% l...

Can the 62 Day X-ray Period of ULX M82 X-1 Be Due to a Precessing Accretion Disk?  

NASA Technical Reports Server (NTRS)

We have analyzed all the archival RXTE/PCA monitoring observations of the ultraluminous X-ray source (ULX) M82 X-1 in order to study the properties of its previously discovered 62 day X-ray period (Kaaret & Feng 2007). Based on the high coherence of the modulation it has been argued that the observed period is the orbital period of the binary. Utilizing a much longer data set than in previous studies we find: (1) The phase-resolved X-ray (3-15 keV) energy spectra - modeled with a thermal accretion disk and a power-law corona - suggest that the accretion disk's contribution to the total flux is responsible for the overall periodic modulation while the power-law flux remains approximately constant with phase. (2) Suggestive evidence for a sudden phase shift-of approximately 0.3 in phase (20 days)-between the first and the second halves of the light curve separated by roughly 1000 days. If confirmed, the implied timescale to change the period is approx. = 10 yrs, which is exceptionally fast for an orbital phenomenon. These independent pieces of evidence are consistent with the 62 day period being due to a precessing accretion disk, similar to the so-called super-orbital periods observed in systems like Her X-1, LMC X-4, and SS433. However, the timing evidence for a change in the period needs to be confirmed with additional observations. This should be possible with further monitoring of M82 with instruments such as the X-ray telescope (XRT) on board Swift.

“Nothing Special, Everything Is Maamuli”: Socio-Cultural and Family Practices Influencing the Perinatal Period in Urban India  

PubMed Central

Background Globally, India contributes the largest share in sheer numbers to the burden of maternal and infant under-nutrition, morbidity and mortality. A major gap in our knowledge is how socio-cultural practices and beliefs influence the perinatal period and thus perinatal outcomes, particularly in the rapidly growing urban setting. Methods and Findings Using data from a qualitative study in urban south India, including in-depth interviews with 36 women who had recently been through childbirth as well as observations of family life and clinic encounters, we explored the territory of familial, cultural and traditional practices and beliefs influencing women and their families through pregnancy, childbirth and infancy. We found that while there were some similarities in cultural practices to those described before in studies from low resource village settings, there are changing practices and ideas. Fertility concerns dominate women’s experience of married life; notions of gender preference and ideal family size are changing rapidly in response to the urban context; however inter-generational family pressures are still considerable. While a rich repertoire of cultural practices persists throughout the perinatal continuum, their existence is normalised and even underplayed. In terms of diet and nutrition, traditional messages including notions of ‘hot’ and ‘cold’ foods, are stronger than health messages; however breastfeeding is the cultural norm and the practice of delayed breastfeeding appears to be disappearing in this urban setting. Marriage, pregnancy and childbirth are so much part of the norm for women, that there is little expectation of individual choice in any of these major life events. Conclusions A greater understanding is needed of the dynamic factors shaping the perinatal period in urban India, including an acknowledgment of the health promoting as well as potentially harmful cultural practices and the critical role of the family. This will help plan culturally appropriate integrated perinatal health care. PMID:25369447

African Easterly Waves in 30-day High-Resolution Global Simulations: A Case Study During the 2006 NAMMA Period  

NASA Technical Reports Server (NTRS)

In this study, extended -range (30 -day) high-resolution simulations with the NASA global mesoscale model are conducted to simulate the initiation and propagation of six consecutive African easterly waves (AEWs) from late August to September 2006 and their association with hurricane formation. It is shown that the statistical characteristics of individual AEWs are realistically simulated with larger errors in the 5th and 6th AEWs. Remarkable simulations of a mean African easterly jet (AEJ) are also obtained. Nine additional 30 -day experiments suggest that although land surface processes might contribute to the predictability of the AEJ and AEWs, the initiation and detailed evolution of AEWs still depend on the accurate representation of dynamic and land surface initial conditions and their time -varying nonlinear interactions. Of interest is the potential to extend the lead time for predicting hurricane formation (e.g., a lead time of up to 22 days) as the 4th AEW is realistically simulated.

The influence of protozoa with a filtered and non-filtered seawater culture of Tetraselmis sp., and effects to the bacterial and algal communities over 10days.  

PubMed

In this study a filter was used to remove protozoa and its effects on a Tetraselmis sp. culture were evaluated in terms of final total lipid, final total dry weight, cell counts, and both the bacterial and algal communities. The protozoa species observed within this study was identified as Cohnilembus reniformis. It was observed that on the final day no C. reniformis were present in filtered cultures compared to the non-filtered culture which contained 40±3 C. reniformis/mL. The presence of C. reniformis within the culture did not affect the total lipid or the total dry weight recovered, suggesting that Tetraselmis sp. was capable of surviving and growing in the presence of C. reniformis. Overall it is suggested that an 11?m filter was effective at removing protozoa, though growing a microalgae culture without filtration did not show any significant effect. PMID:25314666

Extra long period (20-40 day) oscillations in the mesospheric and lower thermospheric winds: observations in Canada, Europe and Japan, and considerations of possible solar influences  

NASA Astrophysics Data System (ADS)

An extra long period (20-40 day) oscillation has been identified in the mesospheric and lower thermospheric (60-100 km) winds observed simultaneously by radars (MF, LF) at four sites from /70°N to /30°N in the northern hemisphere during the winter of 1995//1996. A long-term (1980-1999) investigation of this oscillation at Saskatoon and Collm is also carried out to obtain climatological and statistical characteristics. Spectral analysis has shown that this oscillation is a common feature of the winter (November-March) atmosphere, having strong amplitudes throughout the mesosphere (~10m/s) and lower thermosphere (~5m/s), and being much stronger at mid-low latitudes. Although the oscillation has a climatology similar to the long period normal mode planetary waves (10-16 day), the phases at the various sites are very similar, and not consistent with a freely propagating wave. Comparisons with geomagnetic//solar wind parameters and solar UV radiation suggest that the oscillation could be related to the short-term solar rotation period (ca. 27 days) in some way. However the range of observed wind periods is very broad and this raises questions about this interpretation. Nevertheless the inter-annual variations of this 20-40 day oscillation indicate a weak 11-year solar cycle correlation in the mesosphere (positive) and the lower thermosphere (negative). Also, the cross-correlation between the winds and solar radiation shows significant quasi 27-day correlation and the wind lags behind the solar radiation a few days in the mesosphere. In general it is implied that the atmosphere could react to the solar activity in an indirect way due to certain dynamical mechanisms.

Swift Observations of the High-mass X-Ray Binary IGR J16283-4838 Unveil a 288 Day Orbital Period  

NASA Astrophysics Data System (ADS)

We report on the temporal and spectral properties of the high-mass X-ray binary IGR J16283-4838 in the hard X-ray band. We searched the first 88 months of Swift Burst Alert Telescope (BAT) survey data for long-term periodic modulations. We also investigated the broad band (0.2-150 keV) spectral properties of IGR J16283-4838 complementing the BAT dataset with soft X-ray data from the available Swift-XRT pointed observations. The BAT light curve of IGR J16283-4838 revealed a periodic modulation at Po = 287.6 ± 1.7 days (with a significance higher than 4 standard deviations). The profile of the light curve folded at Po shows a sharp peak lasting ~12 days over a flat plateau. The long-term light curve also shows a ~300 day interval of prolonged enhanced emission. The observed phenomenology suggests that IGR J16283-4838 has a Be nature, where the narrow periodic peaks and the ~300 day outburst can be interpreted as Type I and Type II outbursts, respectively. The broad band 0.2-150 keV spectrum can be described with an absorbed power-law and a steepening in the BAT energy range.

Evidence for an ~80 day periodicity in the X-ray transient pulsar XTE J1946+274  

E-print Network

We report evidence for an ~ 80 d periodicity in the X-ray flux of the hard transient pulsar XTE J1946+274. The 1.3-12 keV light curve obtained with the RossiXTE All Sky Monitor shows five regularly spaced flares over a ~ 1 year baseline starting from the outburst onset in Sept. 1998. The first and strongest flare is somewhat longer than the subsequent four flares, which recur in a fairly periodic fashion. This suggests that the profile of the first flare is dominated by the time variability of the Be star ejection episode, while the following four flares are primarily caused by the neutron star motion along an eccentric orbit.

Kepler and the seven dwarfs: detection of low-level day-time-scale periodic photometric variations in white dwarfs  

NASA Astrophysics Data System (ADS)

We make use of the high photometric precision of Kepler to search for periodic modulations among 14 normal (DA- and DB-type, likely non-magnetic) hot white dwarfs (WDs). In five, and possibly up to seven of the WDs, we detect periodic, ˜2 h-10 d, variations, with semi-amplitudes of 60-2000 ppm, lower than ever seen in WDs. We consider various explanations: WD rotation combined with magnetic cool spots; rotation combined with magnetic dichroism; rotation combined with hotspots from an interstellar-medium accretion flow; transits by size ˜50-200 km objects; relativistic beaming due to reflex motion caused by a cool companion WD; or reflection/re-radiation of the primary WD light by a brown-dwarf or giant-planet companion, undergoing illumination phases as it orbits the WD. Each mechanism could be behind some of the variable WDs, but could not be responsible for all five to seven variable cases. Alternatively, the periodicity may arise from UV metal-line opacity, associated with accretion of rocky material, a phenomenon seen in ˜50 per cent of hot WDs. Non-uniform UV opacity, combined with WD rotation and fluorescent optical re-emission of the absorbed UV energy, could perhaps explain our findings. Even if reflection by a planet is the cause in only a few of the seven cases, it would imply that hot Jupiters are very common around WDs. If some of the rotation-related mechanisms are at work, then normal WDs rotate as slowly as do peculiar WDs, the only kind for which precise rotation measurements have been possible to date.

Morbidity and mortality in the thirty-day period following total hip arthroplasty: risk factors and incidence.  

PubMed

The study sought to ascertain the incidence rates and risk factors for 30-day post-operative complications after primary total hip arthroplasty (THA). Complications were categorized as systemic or local and subcategorized as major or minor. There were 17,640 individuals who received primary THA identified from the 2006-2011 ACS NSQIP. The mortality rate was 0.35% and complications occurred in 4.9%. Age groups ? 80 years (P <0.001) and 70-79 years old (P = 0.003), and renal insufficiency (P = 0.02) best predicted mortality. Age ?80 years (P <0.001) and cardiac disease (P = 0.01) were the strongest predictors of developing any postoperative complication. Morbid obesity (P <0.001) and operative time > 141 minutes (P <0.001) were strongly associated with the development of major local complications. PMID:24973000

The metabolism of phospholipids oscillates rhythmically in cultures of fibroblasts and is regulated by the clock protein PERIOD 1.  

PubMed

The mammalian circadian timing system is composed of countless cell oscillators distributed throughout the body and central pacemakers regulating temporal physiology and behavior. Peripheral clocks display circadian rhythms in gene expression both in vivo and in culture. We examined the biosynthesis of phospholipids as well as the expression of the clock gene period 1 (Per1) and its potential involvement in the regulation of the phospholipid metabolism in cultured quiescent NIH 3T3 cells synchronized by a 2 h serum shock. A 30 min pulse of radiolabeled precursor was given at phases ranging from 0.5 to 62 h after serum treatment. We observed a daily rhythm in the phospholipid labeling that persisted at least for two cycles, with levels significantly decreasing 29 and 58 h after treatment. Per1 expression exhibited a rapid and transient induction and a daily rhythmicity in antiphase to the lipid labeling. After Per1 expression knockdown, the rhythm of phospholipid labeling was lost. Furthermore, in cultures of CLOCK mutant fibroblasts--cells with a clock mechanism impairment--PER1 was equally expressed at all times examined and the phospholipid labeling did not oscillate. The results demonstrate that the biosynthesis of phospholipids oscillates daily in cultured fibroblasts by an endogenous clock mechanism involving Per1 expression. PMID:14715703

HD 17156b: A Transiting Planet with a 21.2 Day Period and an Eccentric Orbit  

E-print Network

We report the detection of transits by the 3.1 M_Jup companion to the V=8.17 G0V star HD 17156. The transit was observed by three independant observers on Sept. 9/10, 2007 (two in central Italy and one in the Canary Islands), who obtained detections at confidence levels of 3.0 sigma, 5.3 sigma, and 7.9 sigma, respectively. The observations were carried out under the auspices of the Transitsearch.org network, which organizes follow-up photometric transit searches of known planet-bearing stars during the time intervals when transits are expected to possibly occur. Analyses of the 7.9 sigma data set indicates a transit depth d=0.0062+/-0.0004, and a transit duration t=186+/-5 min. These values are consistent with the transit of a Jupiter-sized planet with an impact parameter b=a*cos(i)/R_star ~ 0.8. This planet occupies a unique regime among known transiting extrasolar planets, both as a result of its large orbital eccentricity (e=0.67) and long orbital period (P=21.2 d). The planet receives a 26-fold variation in insolation during the course of its orbit, which will make it a useful object for characterization of exoplanetary atmospheric dynamics.

Natural Variation in the Drosophila melanogaster Clock Gene Period Modulates Splicing of Its 3?-Terminal Intron and Mid-Day Siesta  

PubMed Central

Drosophila melanogaster exhibits circadian (?24 hr) regulated morning and evening bouts of activity that are separated by a mid-day siesta. Increases in daily ambient temperature are accompanied by a progressively longer mid-day siesta and delayed evening activity. Presumably, this behavioral plasticity reflects an adaptive response that endows D. melanogaster with the ability to temporally optimize daily activity levels over a wide range of physiologically relevant temperatures. For example, the shift in activity towards the cooler nighttime hours on hot days might minimize the risks associated with exposure to mid-day heat, whereas on cold days activity is favored during the warmer daytime hours. These temperature-induced shifts in the distribution of daily activity are partly based on the thermal sensitive splicing of an intron found in the 3? untranslated region (UTR) of the circadian clock gene termed period (per). As temperature decreases, splicing of this 3?-terminal intron (termed dmpi8) is gradually increased, which is causally linked to a shorter mid-day siesta. Herein we identify several natural polymorphisms in the per 3? UTR from wild-caught populations of flies originating along the east coast of the United States. Two non-intronic closely spaced single nucleotide polymorphisms (SNPs) modulate dmpi8 splicing efficiency, with the least efficiently spliced version associated with a longer mid-day siesta, especially at lower temperatures. Although these SNPs modulate the splicing efficiency of dmpi8 they have little to no effect on its thermal responsiveness, consistent with the notion that the suboptimal 5? and 3? splice sites of the dmpi8 intron are the primary cis-acting elements mediating temperature regulation. Our results demonstrate that natural variations in the per gene can modulate the splicing efficiency of the dmpi8 intron and the daily distribution of activity, providing natural examples for the involvement of dmpi8 splicing in the thermal adaptation of behavioral programs in D. melanogaster.

Socio-cultural factors surrounding mental distress during the perinatal period in Zambia: a qualitative investigation  

PubMed Central

Background The presence of mental distress during pregnancy and after childbirth imposes detrimental developmental and health consequences for families in all nations. In Zambia, the Ministry of Health (MoH) has proposed a more comprehensive approach towards mental health care, recognizing the importance of the mental health of women during the perinatal period. Aim The study explores factors contributing to mental distress during the perinatal period of motherhood in Zambia. Methods A qualitative study was conducted in Lusaka, Zambia with nineteen focus groups comprising 149 women and men from primary health facilities and schools respectively. Findings There are high levels of mental distress in four domains: worry about HIV status and testing; uncertainty about survival from childbirth; lack of social support; and vulnerability/oppression. Conclusion Identifying mental distress and prompt referral for interventions is critical to improving the mental health of the mother and prevent the effects of mental distress on the baby. Recommendation Strategies should be put in place to ensure pregnant women are screened for possible perinatal mental health problems during their visit to antenatal clinic and referral made to qualified mental health professionals. In addition further research is recommended in order to facilitate evidence based mental health policy formulation and implementation in Zambia. PMID:22954173

Blood culture collection technique and pneumococcal surveillance in Malawi during the four year period 2003–2006: an observational study  

PubMed Central

Background Blood culture surveillance will be used for assessing the public health effectiveness of pneumococcal conjugate vaccines in Africa. Between 2003 and 2006 we assessed blood culture outcome and performance in adult patients in the central public hospital in Blantyre, Malawi, before and after the introduction of a dedicated nurse led blood culture team. Methods A prospective observational study. Results Following the introduction of a specialised blood culture team in 2005, the proportion of contaminated cultures decreased (19.6% in 2003 to 5.0% in 2006), blood volume cultured increased and pneumococcal recovery increased significantly from 2.8% of all blood cultures to 6.1%. With each extra 1 ml of blood cultured the odds of recovering a pneumococcus increased by 18%. Conclusion Standardisation and assessment of blood culture performance (blood volume and contamination rate) should be incorporated into pneumococcal disease surveillance activities where routine blood culture practice is constrained by limited resources.

A Whole-Genome Microarray Study of Arabidopsis thaliana Semisolid Callus Cultures Exposed to Microgravity and Nonmicrogravity Related Spaceflight Conditions for 5 Days on Board of Shenzhou 8  

PubMed Central

The Simbox mission was the first joint space project between Germany and China in November 2011. Eleven-day-old Arabidopsis thaliana wild type semisolid callus cultures were integrated into fully automated plant cultivation containers and exposed to spaceflight conditions within the Simbox hardware on board of the spacecraft Shenzhou 8. The related ground experiment was conducted under similar conditions. The use of an in-flight centrifuge provided a 1?g gravitational field in space. The cells were metabolically quenched after 5 days via RNAlater injection. The impact on the Arabidopsis transcriptome was investigated by means of whole-genome gene expression analysis. The results show a major impact of nonmicrogravity related spaceflight conditions. Genes that were significantly altered in transcript abundance are mainly involved in protein phosphorylation and MAPK cascade-related signaling processes, as well as in the cellular defense and stress responses. In contrast to short-term effects of microgravity (seconds, minutes), this mission identified only minor changes after 5 days of microgravity. These concerned genes coding for proteins involved in the plastid-associated translation machinery, mitochondrial electron transport, and energy production. PMID:25654111

The analysis of fundamental period of cultural heritage buildings: experimental data for church towers in Basilicata (Southern Italy)  

NASA Astrophysics Data System (ADS)

Seismic hazard is among the main factors conditioning the conservation of historical centres and cultural heritage located in them. This consideration is suitable especially for downtown areas located in Italy, whose territory is prone to seismic hazards, in the southern area especially. As a matter of fact, the historical sources inform us that most of monuments located in Southern Italy suffered damage and consequent restoration or rebuilding due to the earthquake of the past. Therefore, knowing what buildings are the most exposed to the seismic risk can help the stakeholders to fix priority actions aimed at mitigating the effects of future events. Starting from these preliminary remarks, in the framework of the Project PRO_CULT, we started an extensive campaign of measurements of dynamic features of the church towers in some towns of the Basilicata Region (Southern Italy). The aim of the research activity is to assess the fundamental period of such a typology of historical buildings and comparing it with the dynamic features of the foundation soil to put into evidence possible resonance phenomena responsible of an increase of building damage during the seismic shaking. The selection of the towns to be considered as a target of the experimental survey was performed taking into account the availability of written sources dealing with the historical seismic effects suffered by the bell-towers over the centuries with special attention to the sites heavily affected by the 16 December 1857 Basilicata and 23 November 1980 Irpinia-Basilicata earthquakes (Gizzi and Masini 2007). The fundamental period of bell-towers is estimated using ambient noise vibration signals recorded at the highest level of the towers. The techniques used to get the dynamic values are both the Horizontal to Vertical Spectral Ratio (HVSR) and the Horizontal to Horizontal Spectral Ratio (HHSR) (Liberatore et al. 2008). Once the fundamental frequency has been estimated, it is compared with the dynamic features of the soil obtained by free-field measurements. The detailed architectural survey of each investigated tower will also allow correlating the estimated frequencies with the features of the historic building such as structural symmetry, number of storeys and height of the tower, building materials, presence and dimension of openings, presence of tie rods, and presence of adjoining buildings. In this way, we can get new insights for a tentative scheme of typological classification of such historic buildings. References Gizzi F.T., Masini N. 2007.

KELT-6b: A P ~ 7.9 Day Hot Saturn Transiting a Metal-poor Star with a Long-period Companion  

NASA Astrophysics Data System (ADS)

We report the discovery of KELT-6b, a mildly inflated Saturn-mass planet transiting a metal-poor host. The initial transit signal was identified in KELT-North survey data, and the planetary nature of the occulter was established using a combination of follow-up photometry, high-resolution imaging, high-resolution spectroscopy, and precise radial velocity measurements. The fiducial model from a global analysis including constraints from isochrones indicates that the V = 10.38 host star (BD+31 2447) is a mildly evolved, late-F star with T eff = 6102 ± 43 K, log g_\\star =4.07_{-0.07}^{+0.04}, and [Fe/H] = -0.28 ± 0.04, with an inferred mass M sstarf = 1.09 ± 0.04 M ? and radius R_\\star =1.58_{-0.09}^{+0.16} \\,R_\\odot. The planetary companion has mass MP = 0.43 ± 0.05 M Jup, radius R_{P}=1.19_{-0.08}^{+0.13} \\,R_Jup, surface gravity log g_{P}=2.86_{-0.08}^{+0.06}, and density \\rho _{P}=0.31_{-0.08}^{+0.07}\\,g\\,cm^{-3}. The planet is on an orbit with semimajor axis a = 0.079 ± 0.001 AU and eccentricity e=0.22_{-0.10}^{+0.12}, which is roughly consistent with circular, and has ephemeris of T c(BJDTDB) = 2456347.79679 ± 0.00036 and P = 7.845631 ± 0.000046 days. Equally plausible fits that employ empirical constraints on the host-star parameters rather than isochrones yield a larger planet mass and radius by ~4}-7}. KELT-6b has surface gravity and incident flux similar to HD 209458b, but orbits a host that is more metal poor than HD 209458 by ~0.3 dex. Thus, the KELT-6 system offers an opportunity to perform a comparative measurement of two similar planets in similar environments around stars of very different metallicities. The precise radial velocity data also reveal an acceleration indicative of a longer-period third body in the system, although the companion is not detected in Keck adaptive optics images. KELT is a joint project of The Ohio State University, Vanderbilt University, and Lehigh University.

Inter- and intra-individual variation in urinary biomarker concentrations over a 6-day sampling period. Part 2: Personal care product ingredients.  

PubMed

An intensive study was conducted to provide data on intra- and inter-individual variation in urinary excretion of a series of ingredients in personal care products (parabens, triclosan, benzophenones) and bisphenol A (BPA, not expected to be an ingredient) in 8 volunteers over 6 days. Exposure diaries recorded use of personal care products with identified target analytes as ingredients. Participants' usual products were replaced with products without the target analytes for 2 of the 6 days. Urine void volumes and times were recorded. Methyl, ethyl, and n-propylparabens, triclosan, benzophenone-3, and BPA were frequently detected (?70% of samples). Urinary concentrations of the parabens and triclosan were lower on product replacement days. First morning void concentrations correlated moderately to highly with 24-h composite concentrations for all analytes. Intraclass correlation coefficients (ICCs) for spot samples collected on days with usual product use were low for BPA (0.15), moderate for n-propylparaben and methylparaben (0.39 and 0.56, respectively), and high for ethylparaben, benzophenone-3, and triclosan (0.76, 0.81, and 0.934, respectively); ICCs were consistently higher on the basis of cr-adjusted concentrations. Hydration status adjustment methods were assessed by comparing unadjusted and adjusted concentrations to urinary excretion rates (ER, ng/kg-h) for all analytes and samples. Specific gravity-adjusted concentrations correlated slightly better with ER than creatinine-adjusted concentrations. Within-individual variation in biomarker concentrations was highest for methyl and ethylparabens (2 orders of magnitude variation in spot sample concentrations) and lower for the other analytes (1-1.5 orders of magnitude). This dataset provides insight into the design and interpretation of urinary biomonitoring studies for non-persistent chemicals. PMID:24956590

Increase in nitrate uptake by soybean plants during interruption of the dark period with low intensity light  

NASA Technical Reports Server (NTRS)

Diurnal patterns of net NO3- uptake by nonnodulated soybean [Glycine max (L.) Merr. cv. Ransom] plants growing in flowing hydroponic culture at 26 and 16 degrees C root temperatures were measured at hourly intervals during alternate days of a 12-day growth period. Ion chromatography was used to determine removal of NO3- from the culture solution. Day and night periods of 9 and 15 h were used during growth. The night period included two 6-h dark periods and an intervening 3-h period of night interruption by incandescent lamps to effect a long-day photoperiod and repress floral initiation. At both root temperatures, the average specific rates of NO3- uptake were twice as great during the night interruption period as during the day period; they were greater during the day period than during the dark periods; and they were greater during the dark period immediately following the day period than during the later dark period that followed the night interruption. While these average patterns were repetitious among days, measured rates of uptake varied hourly and included intervals of net efflux scattered through the day period and more frequently through the 2 dark periods. Root temperature did not affect the average daily specific rates of uptake or the qualitative relationships among day, dark and night interruption periods of the diurnal cycle.

Discovery of an eccentric 30 days period in the supergiant X-ray binary SAX J1818.6-1703 with INTEGRAL  

E-print Network

SAX J1818.6-1703 is a flaring transient X-ray source serendipitously discovered by BeppoSAX in 1998 during an observation of the Galactic centre. The source was identified as a High-Mass X-ray Binary with an OB SuperGiant companion. Displaying short and bright flares and an unusually very-low quiescent level implying intensity dynamical range as large as 1e3-4, the source was classified as a Supergiant Fast X-ray Transient. The mechanism triggering the different temporal behaviour observed between the classical SGXBs and the recently discovered class of SFXTs is still debated. The discovery of long orbits (>15 d) should help to discriminate between emission models and bring constraints. We analysed archival INTEGRAL data on SAX J1818.6-1703. We built short- and long-term light curves and performed timing analysis in order to study the temporal behaviour of SAX J1818.6-1703 on different time scales. INTEGRAL revealed an unusually long orbital period of 30.0+/-0.2 d and an elapsed accretion phase of ~6 d in the transient SGXB SAX J1818.6-1703. This implies an elliptical orbit and constraints the possible supergiant spectral type between B0.5-1I with eccentricities e~0.3-0.4 (for average fundamental parameters of supergiant stars). During the accretion phase, the source behaved like classical SGXBs. The huge variations of the observed X-ray flux can be explained through accretion of macro-clumps formed within the stellar wind. Our analysis strengthens the model which predicts that SFXTs behave as SGXBs but with different orbital parameters, thus different temporal behaviour.

Influence of a three-day feed and water deprivation period on gut fill, tissue weights, and tissue composition in mature wethers.  

PubMed

Fourteen mature wethers (average BW 71.8 +/- .86 kg) were used to study the effects of feed and water deprivation on the quantity and composition of gastrointestinal tract (GIT) contents and tissues. Sheep (seven/treatment) were randomly assigned to one of two treatments: 1) limit fed 1,400 g/d of a pelleted diet or 2) deprived of feed and water for 3 d. Before euthanasia, sheep were infused i.v. with Evans blue, sodium thiocyanate, and antipyrine to determine plasma, extracellular, and total body water, respectively. Blood samples were obtained for 4 h after the infusions. Sheep were killed by injection of a lethal dose of a general anesthetic and organs were immediately removed, weighed, and sampled. Compared with controls, unfed sheep lost 7.1 kg (9.9%; P < .05) of their BW during the 3-d deprivation period, of which 21.1% was from the stomach contents, 28.1% (P < .05) was from the GIT (stomach + intestine) contents, and 6.7% (P < .02) was from GIT tissues. The weight loss of the liver, lungs, heart, and kidneys each accounted for less than 1% of the total weight loss. Of the total weight loss, 80% (P < .09) was body water. Of total body water loss, 57% (P < .20) was from the intracellular compartment and 29% (P < .06) was from the GIT contents. Total Ca, Na, Mg, Cu, Fe, and Zn losses via fecal + urinary excretion were less or equal to losses from the GIT contents.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:8582843

No Matter How Long the Night, the Day is Sure to Come: Culture and Educational Transformation in Post-Colonial Namibia and Post-Apartheid South Africa  

NASA Astrophysics Data System (ADS)

Following the defeat of Apartheid, the 1990s have witnessed serious attempts by Namibians and South Africans alike to reconstruct their social institutions along democratic lines. While education has not been excluded from these efforts, there is evidence that the new curricula are primarily influenced by western educational models. For example, prescriptions of the International Monetary Fund and the World Bank have been uncritically incorporated into the new educational programme. Consequently the curricula lack an indigenous ingredient, namely the cultural capital of the African masses. It is suggested in this article that the much acclaimed African cultural renaissance in education will only become a reality when educationalists embrace the "pedagogy of hope".

Characterization of 83-kilodalton nonmuscle caldesmon from cultured rat cells: stimulation of actin binding of nonmuscle tropomyosin and periodic localization along microfilaments like tropomyosin  

PubMed Central

Nonmuscle caldesmon purified from cultured rat cells shows a molecular weight of 83,000 on SDS gels, Stokes radius of 60.5 A, and sedimentation coefficient (S20,w) of 3.5 in the presence of reducing agents. These values give a native molecular weight of 87,000 and a frictional ratio of 2.04, suggesting that the molecule is a monomeric, asymmetric protein. In the absence of reducing agents, the protein is self-associated, through disulfide bonds, into oligomers with a molecular weight of 230,000 on SDS gels. These S-S oligomers appear to be responsible for the actin-bundling activity of nonmuscle caldesmon in the absence of reducing agents. Actin binding is saturated at a molar ratio of one 83-kD protein to six actins with an apparent binding constant of 5 X 10(6) M-1. Because of 83-kD nonmuscle caldesmon and tropomyosin are colocalized in stress fibers of cultured cells, we have examined effects of 83-kD protein on the actin binding of cultured cell tropomyosin. Of five isoforms of cultured rat cell tropomyosin, tropomyosin isoforms with high molecular weight values (40,000 and 36,500) show higher affinity to actin than do tropomyosin isoforms with low molecular weight values (32,400 and 32,000) (Matsumura, F., and S. Yamashiro-Matsumura. 1986. J. Biol. Chem. 260:13851-13859). At physiological concentration of KCl (100 mM), 83-kD nonmuscle caldesmon stimulates binding of low molecular weight tropomyosins to actin and increases the apparent binding constant (Ka from 4.4 X 10(5) to 1.5 X 10(6) M-1. In contrast, 83-kD protein has slight stimulation of actin binding of high molecular weight tropomyosins because high molecular weight tropomyosins bind to actin strongly in this condition. As the binding of 83-kD protein to actin is regulated by calcium/calmodulin, 83-kD protein regulates the binding of low molecular weight tropomyosins to actin in a calcium/calmodulin-dependent way. Using monoclonal antibodies to visualize nonmuscle caldesmon along microfilaments or actin filaments reconstituted with purified 83-kD protein, we demonstrate that 83-kD nonmuscle caldesmon is localized periodically along microfilaments or actin filaments with similar periodicity (36 +/- 4 nm) as tropomyosin. These results suggest that 83- kD protein plays an important role in the organization of microfilaments, as well as the control of the motility, through the regulation of the binding of tropomyosin to actin.

Radiometric detection of yeasts in blood cultures of cancer patients.  

PubMed Central

During a 12-month period, 19,457 blood cultures were collected. Yeasts were isolated from 193 cultures derived from 76 cancer patients. Candida albicans or Candida tropicalis accounted for 79% of isolates. Of the three methods compared, the radiometric method required 2.9 days to become positive, "blind" subculture required 2.6 days, and Gram stains required 1 day. However, the radiometric method was clearly superior in detecting positive cultures, since 73% of all cultures were first detected radiometrically, 22% were detected by subculture, and only 5% were detected by Gram stain. Although 93% of the isolates were detected by aerobic culture, five (7%) isolates were obtained only from anaerobic cultures. Seven days of incubation appear to be sufficient for the radiometric detection of yeasts. PMID:7012168

Immunological detection of cytomegalovirus early antigen on monolayers inoculated with urine specimens by centrifugation and cultured for 6 days as alternative to conventional virus isolation.  

PubMed Central

Detection methods for human cytomegalovirus were evaluated with 431 urine samples from 30 bone marrow and 88 kidney transplant recipients. Low-speed centrifugal inoculation was followed by early antigen (EA) detection by means of indirect immunofluorescence with a monoclonal antibody after 1 (EA-1) and 6 (EA-6) days of cultivation. The results were compared with those of conventional virus isolation (CVI). Of 68 positive samples, 49 (72%) were detected with EA-1, 58 (85%) were detected with EA-6, and 43 (63%) were detected with CVI. The combination of EA-1 and EA-6 showed positive results with 66 samples (97%), which is significantly better than with CVI (P less than 0.001). With the exception of one patient, all CVI-negative but EA-positive samples had either significant rises in immunoglobulin G (IgG) or IgA antibody titer or IgM antibodies present in the sera. These data indicate that the method with EA detection can replace CVI, provided that each sample is inoculated in duplicate. Sample 1 is examined after 1 day, and if it is negative, sample 2 is incubated for a further 5 days, followed by detection of cytomegalovirus. PMID:2842371

International Women's Day speech.  

PubMed

The objectives of the International Women's Day are: 1) to celebrate the struggle for women's rights in the economic, social, political, and cultural domain; 2) to reaffirm women's solidarity in the struggle for peace; 3) and to show what women have achieved. In 1988, Uganda's government of the National Resistance Movement created the Ministry of Women in Development. The period 1988-1990 was one of consultations, needs assessment, planning, and recruiting staff for the Ministry. From 1990 to 1993, measurable results have been achieved. The Ministry's gender concerns pertained to the sector policies of the Ministries of Agriculture, Animal Industry and Fisheries, Education, Health, Water, Energy, Minerals, and Environment Protection. Under the Umbrella Project for Women in Development, gender sensitization has been achieved with policy makers in ministries, at district level, and in the media. Gender issues have also been incorporated in the National Political School Curriculum. The Ministry has also trained a corps of 73 women trainers from 38 districts. The Ministry, with funding from DANIDA, collected women's views on the constitution through meetings and seminars in all the districts in the country. Recommendations were submitted in a consolidated report to the Constitution Commission. A pilot para-legal scheme is successfully being implemented in Kamuli district. A community-based pool of legal advisors has been developed. Legal matters that affect both women and men are undertaken at the community level. The economic emancipation of women is a crucial part of the Ministry's mandate. In conjunction with NGOs, pilot credit programs are being run in Mukono, Jinja, Mbale, and Kapchorwa districts. Cross-sectoral programs are in close collaboration with the rural water and sanitation program, the Northern Uganda rehabilitation program, and the integrated Basic Education Pilot Project to be implemented in 8 districts.

Three-dimensional resistivity tomography in extreme coastal terrain amidst dense cultural signals: application to cliff stability assessment at the historic D-Day site  

NASA Astrophysics Data System (ADS)

Pointe du Hoc overlooking the English Channel in Normandy, France was host to one of the most important military engagements of World War II but is vulnerable to cliff collapses that threaten important German fortifications including the forward observation post (OP) and Rudder's command post. The objective of this study is to apply advanced 3-D resistivity tomography towards a detailed site stability assessment with special attention to the two at-risk buildings. 3-D resistivity tomography data sets at Pointe du Hoc in the presence of extreme topography and dense cultural clutter have been successfully acquired, inverted and interpreted. A cliff stability hazard assessment scheme has been designed in which regions of high resistivity are interpreted as zones of open, dry fractures with a moderate mass movement potential. Regions of low resistivity are zones of wet, clay-filled fractures with a high mass movement potential. The OP tomography results indicate that the highest mass movement hazard appears to be associated with the marine caverns at the base of the cliff that are positioned at the point of strongest wave attack. These caverns likely occupy the future site of development of a sea arch that will threaten the OP building. The mass movement potential at the Rudder's command post area is low to moderate. The greatest risk there is associated with soil wedge failures at the top of the cliffs.

Comparative Study of 5-Day and 10-Day Cefditoren Pivoxil Treatments for Recurrent Group A ?-Hemolytic Streptococcus pharyngitis in Children  

PubMed Central

Efficacy of short-course therapy with cephalosporins for treatment of group A ?-hemolytic streptococcus (GABHS) pharyngitis is still controversial. Subjects were 226 children with a history of at least one episode of GABHS pharyngitis. Recurrence within the follow-up period (3 weeks after initiation of therapy) occurred in 7 of the 77 children in the 5-day treatment group and in 1 of the 149 children in the 10-day treatment group; the incidence of recurrence being significantly higher in the 5-day treatment group. Bacteriologic treatment failure (GABHS isolation without overt pharyngitis) at follow-up culture was observed in 7 of the 77 children in the 5-day treatment group and 17 of the 149 children in the 10-day treatment group. There was no statistical difference between the two groups. A 5-day course of oral cephalosporins is not always recommended for treatment of GABHS pharyngitis in children who have repeated episodes of pharyngitis. PMID:20041005

The ultrastructure of rat palatal mucosa maintained in organ culture.  

PubMed Central

Palatal mucosa from neonatal rats was examined by electron microscopy after maintenance in a chemically defined medium in organ culture for periods up to 24 days. Throughout the culture period there was little overall change in the explants. Apart from limited disturbances of the basal lamina complex early in the culture period, and the presence of occasional degenerating keratinocytes after 18 days in vitro, the epithelium displayed an ultrastructure comparable with that at the time of explantation. The connective tissue showed greater changes, but despite considerable cell death a viable cell population apparently capable of both phagocytosis and synthesis of extracellular material was maintained. It is concluded that this organ culture system is a valid model for experimental investigations into the behaviour of oral mucosa.

Biomimetic bone mechanotransduction modeling in neonatal rat femur organ cultures: structural verification of proof of concept  

PubMed Central

The goal of this work was to develop and validate a whole bone organ culture model to be utilized in biomimetic mechanotransduction research. Femurs harvested from 2-day-old neonatal rat pups were maintained in culture for 1 week post-harvest and assessed for growth and viability. For stimulation studies, femurs were physiologically stimulated for 350 cycles 24 h post-harvest then maintained in culture for 1 week at which time structural tests were conducted. Comparing 1 and 8 days in culture, bones grew significantly in size over the 7-day culture period. In addition, histology supported adequate diffusion and organ viability at 2 weeks in culture. For stimulation studies, 350 cycles of physiologic loading 24 h post-harvest resulted in increased bone strength over the 7-day culture period. In this work, structural proof of concept was established for the use of whole bone organ cultures as mechanotransduction models. Specifically, this work established that these cultures grow and remain viable in culture, are adequately nourished via diffusion and are capable of responding to a brief bout of mechanical stimulation with an increase in strength.

Paradoxical effect of supplementary progesterone between Day 3 and Day 7 on corpus luteum function and conceptus development in cattle.  

PubMed

The aim of the present study was to investigate the effect of short-term progesterone (P4) supplementation during the early metoestrous period on circulating P4 concentrations and conceptus development in cattle. The oestrous cycles of cross-bred beef heifers were synchronised using a 7-day P4-releasing intravaginal device (PRID® Delta; 1.55 g P4) treatment with administration of a prostaglandin F(2?) analogue (Enzaprost; CEVA Sante Animale) the day before PRID® Delta removal. Only those heifers recorded in standing oestrus (Day 0) were used. In Experiment 1, heifers were randomly assigned to one of five groups: (1) control: no treatment; (2) placebo: insertion of a blank device (no P4) from Day 3 to Day 7; (3) insertion of a PRID® Delta from Day 3 to Day 7; (4) insertion of a PRID® Delta from Day 3 to Day 5; or (5) insertion of a PRID® Delta from Day 5 to Day 7. In vitro-produced blastocysts were transferred to each heifer in Groups 2-5 on Day 7 (n=10 blastocysts per heifer) and conceptuses were recovered when heifers were killed on Day 14. Based on the outcome of Experiment 1, in Experiment 2 heifers were artificially inseminated at oestrus and randomly assigned to one of three treatment groups: (1) placebo; (2) PRID from Day 3 to Day 5; or (3) PRID from Day 3 to Day 7. All heifers were killed on Day 16 and recovered conceptuses were incubated in synthetic oviducal fluid medium for 24 h; spent media and uterine flushes were analysed for interferon-? (IFNT). In both experiments, daily blood samples were taken to determined serum P4 concentrations. Data were analysed using the PROC MIXED procedure of SAS (SAS Institute, Cary, NC, USA). Insertion of a PRID resulted in an increase (P<0.05) in serum P4 that declined following removal. In Experiment 1, P4 supplementation from Day 3 to Day 5 (17.0±1.4 mm) or Day 3 to Day 7 (11.3±2.3 mm) increased conceptus length compared with placebo (2.1±1.8 mm). Serum P4 was significantly lower from Day 9 to Day 14 (P<0.05) and the weight of the Day 14 corpus luteum (CL) was lower in the PRID Day 3-7 group than the placebo or control groups. In Experiment 2, supplementation from Day 3 to Day 5 (94.0±18.8 mm) or Day 3 to Day 7 (143.6±20.6 mm) increased conceptus length on Day 16 compared with placebo (50.3±17.4 mm). Serum P4 was significantly lower in the two supplemented groups following PRID removal compared with placebo (P<0.05) and was associated with a lower CL weight in the Day 3-7 group. Conceptus length was strongly correlated with the IFNT concentration in the uterine flush (r=0.58; P=0.011) and spent culture medium (r=0.68; P<0.002). The findings of the present study highlight the somewhat paradoxical effects of P4 supplementation when given in the early metoestrous period in terms of its positive effect on conceptus development and its potentially negative effects on CL lifespan.

Is Screening for Depression in the Perinatal Period Enough? The Co-Occurrence of Depression, Substance Abuse, and Intimate Partner Violence in Culturally Diverse Pregnant Women  

PubMed Central

Abstract Background The perinatal period provides unique opportunities to identify and intervene with the co-occurrence of perinatal depression, intimate partner violence (IPV), and substance use problems. Psychosocial screening recommended for women seen in maternal child health settings tends to target single rather than multiple risk factors; there is limited research examining the co-occurrence of these issues especially in racially and ethnically diverse women across the perinatal period. These analyses explore the relationships of sociodemographic, psychosocial, and behavioral characteristics in a large, diverse sample of women. Method Women receiving perinatal services at routinely scheduled visits, including the 6-week postpartum visit, were recruited from 10 community obstetric/gynecologic clinics. Data were collected on perinatal depression, IPV, maternal substance use, and sociodemographic characteristics by bilingual, bicultural research assistants. Results A total of 1868 women were screened, 1526 (82%) Latina, 1099 (58.8%) interviewed in Spanish; 20.4% (n=382) screened positive for depressive symptoms based on an Edinburgh Postnatal Depression Scale score of 10 or above, 20.9% reported harmful drinking, 4.3% reported drug use, 23% reported substance use problems, and 3.5% reported current or recent IPV. Women who were Black, Asian, Pacific Islander, or other race/ethnicity had greater odds for depressive symptoms relative to women who were Hispanic or Latino (odds ratio [OR]=1.81, p=0.005). Women reporting substance use problems (OR=2.37, p<0.0001) and IPV (OR=3.98, p<0.0001) had higher odds for depressive symptoms. Conclusion In a predominately Latina sample, 1 in 5 mothers (20.4%) screened positive for depressive symptoms and over one third (36.7%) reported one or more psychosocial issues during the perinatal period. Screening for multiple risk factors rather than just one can help clinicians tailor interventions for the successful management of psychosocial issues. PMID:23931153

Non-spore forming eubacteria isolated at an altitude of 20,000 m in Earth's atmosphere: extended incubation periods needed for culture-based assays  

USGS Publications Warehouse

On 13 August 2004, an atmospheric sample was collected at an altitude of 20,000 m along a west to east transect over the continental United States by NASA’s Stratospheric and Cosmic Dust Program. This sample was then shipped to the US Geological Survey’s Global Desert Dust program for microbiological analyses. This sample, which was plated on a low nutrient agar to determine if cultivable microorganisms were present, produced 590 small yellow to off-white colonies after approximately 7 weeks of incubation at room-temperature. Of 50 colonies selected for identification using 16S rRNA sequencing, 41 belonged to the family Micrococcaceae, seven to the family Microbacteriaceae, one to the genus Staphylococcus, and one to the genus Brevibacterium. All of the isolates identified were non-spore-forming pigmented bacteria, and their presence in this sample illustrate that it is not unusual to recover viable microbes at extreme altitudes. Additionally, the extended period required to initiate growth demonstrates the need for lengthy incubation periods when analyzing high-altitude samples for cultivable microorganisms.

Embryonic mouse pre-metatarsal development in organ culture  

NASA Technical Reports Server (NTRS)

Embryonic mouse pre-metatarsals were removed from embryos at 13 days of gestation and cultured in a defined, serum-free medium for up to 15 days. By histological analysis, we observe that the cultured pre-metatarsal tissue undergoes a similar developmental profile as pre-metatarsals growing normally in vivo. The initial mesenchyme condensation regions undergo differentiation and morphogenesis to form distinct rods made up of cartilage tissue. A marker of this differentiation step is the synthesis of type II collagen. Metabolic labelling, pepsin digestion, SDS-PAGE, and autoradiography were used to demonstrate this protein when cartilage tissue is present in the cultures. After additional culture time, terminal chondrocyte differentiation and morphogenesis take place in specific regions of the cartilage rods to form bands of hypertrophied chondrocytes. One marker of this differentiation step is the synthesis of the enzyme alkaline phosphatase. We have measured the activity of this enzyme throughout the culture period and see a substantial increase at the time of terminal chondrocyte differentiation. Another feature of hypertrophied chondrocytes is that the matrix around the cells becomes calcified. Calcified matrix in our cultured pre-metatarsals was visualized by staining with alizarin red. By supplementing the defined culture medium with ITS, we observed that terminal chondrocyte differentiation took place in a shorter culture time. Supplementation of the medium with serum results in a similar acceleration of terminal differentiation, and, with additional culture time, an osteoid-like matrix forms around the central region of the rods.

Perfusion enhanced polydimethylsiloxane based scaffold cell culturing system for multi-well drug screening platform.  

PubMed

Conventional two-dimensional cultures in monolayer and sandwich configuration have been used as a model for in vitro drug testing. However, these culture configurations do not present the actual in vivo liver cytoarchitecture for the hepatocytes cultures and thus they may compromise the cells liver-specific functions and their cuboidal morphology over longer term culture. In this study, we present a three-dimensional polydimethylsiloxane (PDMS) scaffold with interconnected spherical macropores for the culturing of rat liver cells (hepatocytes). The scaffolds were integrated into our perfusion enhanced bioreactor to improve the nutrients and gas supply for cell cultures. The liver-specific functions of the cell culture were assessed by their albumin and urea production, and the changes in the cell morphology were tracked by immunofluorescence staining over 9 days of culture period. N-Acetyl-Para-Amino-Phenol (acetaminophen) was used as drug model to investigate the response of cells to drug in our scaffold-bioreactor system. Our experimental results revealed that the perfusion enhanced PDMS-based scaffold system provides a more conducive microenvironment with better cell-to-cell contacts among the hepatocytes that maintains the culture specific enzymatic functions and their cuboidal morphology during the culturing period. The numerical simulation results further showed improved oxygen distribution within the culturing chamber with the scaffold providing an additional function of shielding the cell cultures from the potentially detrimental fluid induced shear stresses. In conclusion, this study could serve a crucial role as a platform for future preclinical hepatotoxicity testing. PMID:24399780

Stress-Induced Changes in the Expression of the Clock Protein PERIOD1 in the Rat Limbic Forebrain and Hypothalamus: Role of Stress Type, Time of Day, and Predictability  

PubMed Central

Stressful events can disrupt circadian rhythms in mammals but mechanisms underlying this disruption remain largely unknown. One hypothesis is that stress alters circadian protein expression in the forebrain, leading to functional dysregulation of the brain circadian network and consequent disruption of circadian physiological and behavioral rhythms. Here we characterized the effects of several different stressors on the expression of the core clock protein, PER1 and the activity marker, FOS in select forebrain and hypothalamic nuclei in rats. We found that acute exposure to processive stressors, restraint and forced swim, elevated PER1 and FOS expression in the paraventricular and dorsomedial hypothalamic nuclei and piriform cortex but suppressed PER1 and FOS levels exclusively in the central nucleus of the amygdala (CEAl) and oval nucleus of the bed nucleus of the stria terminalis (BNSTov). Conversely, systemic stressors, interleukin-1? and 2-Deoxy-D-glucose, increased PER1 and FOS levels in all regions studied, including the CEAl and BNSTov. PER1 levels in the suprachiasmatic nucleus (SCN), the master pacemaker, were unaffected by any of the stress manipulations. The effect of stress on PER1 and FOS was modulated by time of day and, in the case of daily restraint, by predictability. These results demonstrate that the expression of PER1 in the forebrain is modulated by stress, consistent with the hypothesis that PER1 serves as a link between stress and the brain circadian network. Furthermore, the results show that the mechanisms that control PER1 and FOS expression in CEAl and BNSTov are uniquely sensitive to differences in the type of stressor. Finally, the finding that the effect of stress on PER1 parallels its effect on FOS supports the idea that Per1 functions as an immediate-early gene. Our observations point to a novel role for PER1 as a key player in the interface between stress and circadian rhythms. PMID:25338089

The Time Course of Xylem Differentiation and Its Relation to Deoxyribonucleic Acid Synthesis in Cultured Coleus Stem Segments  

PubMed Central

The relationship between DNA synthesis and wound xylem differentiation was investigated in cultured stem segments of Coleus blumei. The addition of 50 micrograms of indoleacetic acid per liter to the culture medium resulted in a 400 to 500% increase in the number of wound vessel members formed in 7 days. However, the time course of wound vessel member formation was similar in segments cultured in the presence and absence of auxin. In either case, no wound vessel members appeared before the 3rd day of culture, while the majority of wound vessel members appeared on the 4th and 5th days of culture. 3H-Thymidine incorporation into DNA was used to measure changes in the DNA synthetic activity of the tissues during the culture period. Comparatively little 3H-thymidine incorporation occurred during the 1st day of culture. Maximum 3H-thymidine incorporation was observed on the 2nd day of culture, 2 days before the peak period of xylem differentiation. The rate of incorporation of 3H-thymidine into DNA decreased with increasing time in culture after the 2nd day. Auxin at 50 micrograms per liter had no effect on the time course of 3H-thymidine incorporation, although somewhat more 3H-thymidine was incorporated into DNA throughout the culture period in the presence of auxin. The magnitude of this effect was small when compared to the effect of auxin on xylem differentiation. The antimetabolite 5-fluorodeoxyuridine was shown to block DNA synthesis in the cultured stem segments. When the tissues were isolated on media containing 10?6m 5-fluorodeoxyuridine, wound vessel member differentiation was inhibited by approximately 80%, in both the presence and absence of auxin. Thymidine at 10?5m completely overcame the 5-fluorodeoxyuridine inhibition of wound vessel member formation. 5-Fluorodeoxyuridine was effective in blocking xylogenesis only when this substance was supplied to the tissues during the early part of the culture period. 5-Fluorodeoxyuridine had no effect on xylem differentiation when it was applied after the 3rd day of culture.

FINE STRUCTURE OF DIFFERENTIATING MOUSE PANCREATIC EXOCRINE CELLS IN TRANSFILTER CULTURE.  

PubMed

Fine structural observations have been made in the 11-day embryonic mouse of exocrine cells in pancreatic epithelium developing in tissue culture transfilter from salivary gland mesenchyme of the 13-day embryonic mouse. After 2 days in culture, the exocrine cells show increased cytoplasmic density, abundant ribosomes in aggregate or "rosette" form, and expanded profiles of rough-surfaced endoplasmic reticulum. After 3 and 4 days in culture, the cells exhibit continued expansion of the profiles of endoplasmic reticulum, increased amounts of Golgi membranes, and large areas of light density (prozymogen granules). After 5 days in culture, dense zymogen granules are present in the most highly differentiated cells. In addition, at the filter-epithelial surface, at 2 days, small fibers can be discerned which, after 4 days in culture, show obvious periodicity and are thought to be collagen. The significance of these changes, in relation to the mesenchymal effect, to the onset of specific synthesis and to the stabilization of differentiation is discussed. PMID:14128045

The permeability of rat palatal mucosa maintained in organ culture.  

PubMed Central

The intercellular permeability barrier of neonatal rat palatal mucosa maintained in organ culture for periods up to 24 days was studied ultrastructurally using the tracers horseradish peroxidase and lanthanum nitrate. At all time intervals examined the limit of penetration of the tracers corresponded to the level at which the membrane-coating granules were being discharged. However, in the cultured mucosa, extrusion of granules occurred closer to the granular cell-keratin junction after 6 and 12 days in vitro than at other time intervals. This probably is a reflexion of the higher rate of tissue turnover at these times. It is concluded that a permeability barrier comparable with that described in vivo is produced by the epithelium during maintenance inorgan culture and is further evidence of the functional integrity of the tissue in vitro.

Ionospheric Day-to-Day Variability Around the Whole Heliosphere Interval in 2008  

NASA Astrophysics Data System (ADS)

Ionospheric F2 peak electron densities (NmF2) measured at ten ionosonde stations have been analyzed to investigate ionospheric day-to-day variability around the Whole Heliosphere Interval (WHI) in 2008 (Day of Year (DOY) 50 - 140). The ionosonde data showed that there was significant global day-to-day variability in NmF2. This variability had 5-, 7-, 9-, 11-, 13.5-, and 16 - 21-day periodicities. At middle latitudes, the ionosphere appeared to respond directly to the solar-wind and interplanetary-magnetic-field (IMF) induced geomagnetic-activity forcing, with the day-to-day variability having the same periods as those in the solar-wind/IMF and geomagnetic activity. At the geomagnetic Equator, the ionosphere had a strong 7-day periodicity, corresponding to the same periodicity in the IMF B z component. In the equatorial anomaly region, the ionosphere showed more complicated day-to-day variability, dominated by the 9-day periodicity. In addition, there were also periodicities of 11 days and 16 - 21 days in the ionosonde data at some stations. The ionosonde data were compared with the Coupled Magnetosphere Ionosphere Thermosphere (CMIT) simulations that were driven by the observed solar-wind and IMF data during the WHI. The CMIT simulations showed similar ionospheric daily variability seen in the data. They captured the positive and negative responses of the ionosphere at middle latitudes during the first corotating interaction region (CIR) event in the WHI. The response of the model to the second CIR event, however, was relatively weak.

Maintenance of differentiated rat hepatocytes in primary culture.  

PubMed Central

Normal adult rat hepatocytes remained viable and functional for at least 43 days when plated on collagen-coated dishes and fed chemically defined medium supplemented with dimethyl sulfoxide (Me2SO). Hepatocytes isolated by collagenase perfusion and cultured in the presence or absence of Me2SO were (i) examined by light and electron microscopy for morphological changes; (ii) analyzed for the production of albumin and other plasma proteins; and (iii) tested by autoradiography for DNA synthesis. Me2SO-treated cells continued to produce specific plasma proteins during the entire culture period; albumin production was consistently high (11-19 micrograms/ml of culture medium per 24 hr) from day 2 to at least day 43 after plating. Ultrastructural analyses demonstrated that Me2SO-treated hepatocytes resembled those from intact liver in organization of cytoplasmic organelles and cellular junctions. The optimal concentration for observing the morphological and biochemical effects of Me2SO was 2% (vol/vol). We conclude that supplementation of chemically defined medium with Me2SO enables maintenance of differentiated hepatocytes in culture for extended periods of time. Images PMID:3858822

Defrosting Polar Dunes--Changes Over a 26-Day Period  

NASA Technical Reports Server (NTRS)

As the retreat of the south polar winter frost cap became visible in June 1999, high resolution images from the Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) began to show dark spots forming on the surfaces of frost-covered sand dunes. Immediately, the MOC science team began to plan to observe several dune fields more than once, should that opportunity arise, so that the evolution of these dark spots could be documented and studied. Such work will eventually lead to abetter understanding of how the martian polar caps retreat as winter ends and spring unfolds in each hemisphere.

MGS is in a polar orbit, which means that, unlike many other places on Mars, the spacecraft has more opportunities to take pictures of the same place. Dune fields near 87o latitude can be repeatedly viewed; dunes near the equator are not likely to be photographed more than once during the entire MGS mission.

The pictures presented here show changes on a set of nearly pear-shaped sand dunes located on the floor of an unnamed crater at 59oS, 353oW. The picture on the left shows the dunes as they appeared on June 19, 1999, the picture on the right shows the same dunes on July 15, 1999. The dark spots in the June 19picture--indicating areas where frost has sublimed away--became larger by July 15th. In addition, new spots had appeared as of mid-July. If possible, these dunes will be photographed by MOC again in mid-August and each month until the frost is gone.

The pictures shown in (B) (above) are expanded views of portions of the pictures in (A). The 200 meter scale bar equals 656 feet; the 100 meter bar is 328 feet (109 yards) long. All images are illuminated from the upper left; north is toward the upper right.

Malin Space Science Systems and the California Institute of Technology built the MOC using spare hardware from the Mars Observer mission. MSSS operates the camera from its facilities in San Diego, CA. The Jet Propulsion Laboratory's Mars Surveyor Operations Project operates the Mars Global Surveyor spacecraft with its industrial partner, Lockheed Martin Astronautics, from facilities in Pasadena, CA and Denver, CO.

Relationship of safety culture and process safety.  

PubMed

Throughout history, humans have gathered in groups for social, religious, and industrial purposes. As the conglomeration of people interact, a set of underlying values, beliefs, and principles begins to develop that serve to guide behavior within the group. These "guidelines" are commonly referred to as the group culture. Modern-day organizations, including corporations, have developed their own unique cultures derived from the diversity of the organizational interests and the background of the employees. Safety culture, a sub-set of organizational culture, has been a major focus in recent years. This is especially true in the chemical industry due to the series of preventable, safety-related disasters that occurred in the late seventies and eighties. Some of the most notable disasters, during this time period, occurred at Bhopal, Flixborough, and Seveso. However, current events, like the September 11th terrorist attacks and the disintegration of the Columbia shuttle, have caused an assessment of safety culture in a variety of other organizations.

Effect of K+- and kainate-mediated depolarization on survival and functional maturation of GABAergic and glutamatergic neurons in cultures of dissociated mouse cerebellum.  

PubMed

The effect of the depolarizing agents, an elevated potassium concentration (25 mM) or kainic acid (50 microM) on neuronal survival and differentiation was investigated in cultures of dissociated neurons from cerebella of 7-day-old mice. When maintained in the presence of an antimitotic agent such cultures consist primarily of glutamatergic and GABAergic neurons. Cell survival was monitored by measurement of DNA, and differentiation by determining uptake and depolarization coupled release of glutamate (D-aspartate as label) and GABA. The depolarizing agents were added separately or together either from the start of the culture period (7-8 days) or at day 5 in culture. The main findings are that K+ depolarization is important for differentiation of glutamatergic neurons but not for GABAergic neurons. This depolarizing signal is important during the early phase of development in culture. For glutamatergic neurons, kainate may replace K+ as a depolarizing signal whereas in case of the GABAergic neurons, kainate was toxic particularly during the late phase of development. It was further observed that the glutamatergic neurons when maintained in a medium with 5 mM K+ during the first 5 days in culture became sensitive to kainate toxicity when this amino acid was added at day 5. This was not the case when the medium contained 25 mM K+ from the start of the culture period. PMID:9182252

Post-translational control of collagen fibrillogenesis in mineralizing cultures of chick osteoblasts  

NASA Technical Reports Server (NTRS)

Cultured osteoblasts from chick embryo calvaria were used as a model system to investigate the post-translational extracellular mechanisms controlling the macroassembly of collagen fibrils. The results of these studies demonstrated that cultured osteoblasts secreted a collagenous extracellular matrix that assembled and mineralized in a defined temporal and spatial sequence. The assembly of collagen occurred in a polarized fashion, such that successive orthogonal arrays of fibrils formed between successive cell layers proceeding from the culture surface toward the media. Mineralization followed in the same manner, being observed first in the deepest and oldest fibril layers. Collagen fibrillogenesis, the kinetics of cross-link formation, and collagen stability in the extracellular matrix of the cultures were examined over a 30 day culture period. Between days 8 and 12 in culture, collagen fibril diameters increased from < 30 nm to an average of 30-45 nm. Thereafter, diameters ranged in size from 20 to 200 nm. Quantitation of the collagen cross-linking residues, hydroxylysyl pyridinoline (HP) and lysyl pyridinoline (LP), showed that these mature cross-links increased from undetectable levels to concentrations found in normal chick bone. Analysis of the kinetics of their formation by pulse-chase labeling the cultures with [3H]lysine showed a doubling time of approximately 5 days. The relationships between cross-link formation, fibrillogenesis, and collagen stability were examined in cultures treated with beta-aminopropionitrile (beta-APN), a potent inhibitor of lysyl oxidase and cross-link formation. In beta-APN-treated cultures, total collagen synthesis was increased twofold, with no change in mRNA levels for type I collagen, whereas the amount of collagen accumulated in the cell layer was decreased by 50% and mineral deposition was reduced. The rate of collagen retention in the matrix was assessed by pulse-chase analysis of [3H]proline over a 16 day period in control and beta-APN-treated cultures. In control cultures, about 20% of the labeled collagen was lost from the cell layers over a 16 day period compared with > 80% in the presence of beta-APN. The beta-APN-treated cultures also showed a wider diversity of fibril diameters with a median in the > 45-60 nm range. In summary, these data suggest that cross-linking and assembly of collagen fibrils secreted by osteoblasts in vitro occur in a fashion similar to that found in vivo. The rate of cross-link formation is relatively constant and may be correlated with increasing collagen mass.(ABSTRACT TRUNCATED AT 400 WORDS).

Sensitive Periods  

PubMed Central

This chapter reviews sensitive periods in human brain development based on the literature on children raised in institutions. Sensitive experiences occur when experiences are uniquely influential for the development of neural circuitry. Because in humans, we make inferences about sensitive periods from evaluations of complex behaviors, we underestimate the occurrence of sensitive periods at the level of neural circuitry. Although we are most interested in complex behaviors, such as IQ or attachment or externalizing problems, many different sensitive periods at the level of circuits probably underlie these complex behaviors. Results from a number of studies suggest that across most, but not all, domains of development, institutional rearing limited to the first 4–6 months of life is associated with no significant increase risk for long-term adverse effects relative to non-institutionalized children. Beyond that, evidence for sensitive periods is less compelling, meaning that “the earlier the better” rule for enhanced caregiving is a reasonable conclusion at the current state of the science.

[Periodic abstinence: its possibilities].  

PubMed

Experience with family planning mehods requiring periodic sexual abstinence has been varied. During the last decade interest has centered on 2 methods, the cervical mucus and the sympto-thermal, which are based on identifying the onset of the fertile period. During the 1970s, the Australian physicians John and Evelyn Billings developed the cervical mucus method, in which changes in the quanitity and characteristics of cervical mucus are used to determine the moment of ovulation. The sympto-thermal method depends on identification of the slight rise in basal body temperature that occurs in the latter part of the menstrual cycle as well as cervical mucus changes and sometimes the calendar to determine the fertile period. The Catholic Church has been the main proponent of periodic abstinence methods, but since 1973 the World Health Organization has invested US$3.3 million on research in such methods. The Billings method requires differentiating between dry, wet, and very wet mucus in the vagina and between different consistencies of mucus. The method ususally requires 1-3 months for instruction and sexual abstinence is usually recommended for the 1st month. The average number of days of required abstinence was 9 in a study of 66 women and 15-18 in a study of 870 women. Many women with short menstrual cycles do not experience postmenstrual dry days, in which case abstinence may be required as many as 13 days out of 23. 18.8% of users of periodic abstinence methods in 1 North American study became pregnant in the 1st year, but most were using the calendar method. Women who desired to terminate childbearing had only about 1/2 as many failures with periodic abstinence methods as did women wishing to postpone a birth. PMID:12311397

Optimization of adventitious root culture for production of biomass and secondary metabolites in Prunella vulgaris L.  

PubMed

Adventitious root cultures of Prunella vulgaris L. were established in shaking flask system for the production of biomass and secondary metabolites. Adventitious root cultures were induced from callus cultures obtained from leaf explants on solid Murashige and Skoog (MS) medium containing combination of 6-benzyladenine (BA; 1.0 mg l(-1)) and naphthalene acetic acid (NAA; 1.5 mg l(-1)). Thereafter, 0.49 g inoculum was transferred to liquid MS medium supplemented with different concentrations of NAA (0.5-2.0 mg l(-1)). Growth kinetics of adventitious roots was recorded with an interval of 7 days for 49 days period. Highest biomass accumulation (2.13 g/l) was observed in liquid medium containing 1.0 mg l(-1) NAA after 21 days of inoculation. However, other concentrations of NAA also showed similar accumulation pattern but the biomass gradually decreases after 49 days of inoculation. Adventitious roots were collected and dried for investigation of total phenolics (TP), total flavonoids (TF), and antioxidant activities. Higher TPC (0.995 GAE mg/g-DRB) and TFC (6.615 RE mg/g-DRB) were observed in 0.5 mg l(-1) NAA treated cultures. In contrast, higher antioxidant activity (83.53 %) was observed 1.5 mg l(-1) NAA treated cultures. These results are helpful in up scaling of root cultures into bioreactor for secondary metabolites production. PMID:25163888

Barton had recently lost an estimated half a million dollars trading, according to The New York Times. Coincidentally, just a week and a half after the tragedy in Atlanta, the North American Securities Administrators Association (NASAA) released a study condemning the practice of day trading, finding that, of the 4,093 trades in 26 accounts analyzed, "seventy percent of the accounts lost money and were traded in a manner that realized a 100% Risk of Ruin (loss of all funds)." The study concluded, "It is absolutely clear that the average public investor should refrain from short-term trading." This week's In the News looks at the day trading industry and its effectiveness. The eight resources listed provide studies, recent news, background information, and commentary on day trading.

Antibiotic Prescribing Practices for Catheter Urine Culture Results  

PubMed Central

Background: The literature suggests that positive results of catheter urine cultures frequently lead to unnecessary antimicrobial prescribing, which therefore represents an important target for stewardship. Objective: To assess the appropriateness of antibiotic prescribing in response to the results of urine cultures from patients with indwelling urinary catheters. Methods: This retrospective study was conducted at a tertiary care centre and involved adults with indwelling urinary catheters from whom urine specimens were obtained for culture. Patients with positive or negative culture results were identified from microbiology laboratory reports. The medical records of consecutive patients were screened to select a sample of 80 inpatients (40 per group). Abstracted patient histories were independently evaluated by an expert panel of 3 infectious diseases consultants blinded to the decisions of prescribers and of fellow panelists. The primary end point was concordance of each patient’s treatment decision (with respect to the indication) between the expert panel (based on majority agreement, i.e., at least 2 of the 3 expert panelists) and the prescriber. The secondary end points were unnecessary days of therapy and selected outcomes over a predefined period after urine was obtained for culture. Results: A total of 591 charts were screened to generate the targeted number of patients. Baseline demographic characteristics were comparable for the 2 groups, except antibiotic exposure before urine collection was significantly more frequent for the group with negative culture results. The treatment decision was concordant in 40% (16/40) of the patients with a positive culture result and 85% (34/40) of those with a negative culture result (p < 0.001). The most common reason for discordance was administration of antibiotics when not indicated (23 of 24 patients with a positive result and 5 of 6 patients with a negative result), which accounted for 165 and 32 unnecessary days of therapy per 1000 inpatient-days, respectively (p < 0.001). Adverse effects occurred in 2 of the 23 patients with a positive result who received antibiotics that were not indicated. Conclusions: Appropriateness of antibiotic prescribing, as measured by concordance of decisions between the expert panel and prescribers, was more common among patients with negative urine culture results than among those with positive results. However, there is an opportunity to improve prescribing for both groups through antimicrobial stewardship initiatives. Unnecessary days of therapy and adverse effects were more common in patients with a positive culture result. PMID:23467594

Sidereal and Solar Day  

NSDL National Science Digital Library

The Sidereal and Solar Day model illustrates the difference between the sidereal and solar day. The planets of our solar system both orbit around Sun and rotate on their axis. These two rotations allow for multiple definitions of what a day is. This simulation shows the orbit and rotation of a planet (blue) around Sun (orange). It uses an orange arrow to represent where Sun would be seen in the sky relative to the background stars. A point on the rotating planet is shown with a red arrow to indicate where that point faces relative to the background stars. In order to account for the true scale of the distance of the stars away from the planer, a longer red arrow from Sun points in the same direction as the arrow on the planet to indicate where this point faces relative to the background stars. Users can toggle between the geocentric and heliocentric point of view. The parameters are initially set to model the orbit and rotation of Earth. Sidereal and Solar Day model was created using the Easy Java Simulations (EJS) modeling tool. It is distributed as a ready-to-run (compiled) Java archive. Double clicking the ejs_astronomy_SiderealSolarDay.jar file will run the program if Java is installed.

Morphological Changes of Benign Prostatic Hyperplasia in Culture  

PubMed Central

A technique is described for the culture of slices of benign prostatic hyperplasia (BPH) for periods of a week in organ culture. Under these conditions tissue repair took place, resulting in a covering layer of transitional epithelium which formed around the explant and spread out laterally as a monolayer. Autoradiography and studies with [3H]thymidine uptake suggested that the repair activity, which reached a peak at Day 3 in culture, was the centre of biochemical activity, overshadowing that of the rest of the explant. Necrosis of the explant base tended to develop abruptly during the first day of culture but thereafter remained stable. The epithelium was well preserved morphologically, but explant acid phosphatase activity fell progressively. No morphological response to testosterone (10-5 mol/l) or stilboestrol diphosphate (10-5 mol/l) was seen. Attention is drawn to a possible source of misinterpretation of results offered by the uptake of [3H]thymidine into DNA in organ culture.

Candidates for future cultural neuroscience research include cultural variations in the default (resting) network, which may be social; regulation and inhibition of feelings, thoughts, and actions; prejudice and dehumanization; and neural signatures of fundamental warmth and competence judgments.

Most current 3-D co-culture methods lack the ability to effectively separate 2 cell populations after the culture period, which is important for simultaneously analyzing the reciprocal effects of each cell type on the other. Here, we detail the development of a 3-D hydrogel co-culture system that allows us to culture different cell types for up to 7 days and subsequently separate and isolate the different cell populations using enzyme-sensitive glues. Separable 3-D co-culture laminates were prepared by laminating PEG-based hydrogels with enzyme-degradable hydrogel adhesives. Encapsulated cell populations exhibited good segregation with well-defined interfaces. Furthermore, constructs can be separated on-demand upon addition of the appropriate enzyme and cell viability remains high throughout the culture period, even after laminate separation. This platform offers great potential for a variety of basic cell signaling studies as the incorporation of an enzyme-sensitive adhesive interface allows the on-demand separation of individual cell populations for immediate analysis or further culture to examine persistence of co-culture effects and paracrine signaling on cell populations.

Jupiter Night and Day  

NASA Technical Reports Server (NTRS)

Day and night side narrow angle images taken on January 1, 2001 illustrating storms visible on the day side which are the sources of visible lightning when viewed on the night side. The images have been enhanced in contrast. Note the two day-side occurrences of high clouds, in the upper and lower parts of the image, are coincident with lightning storms seen on the darkside. The storms occur at 34.5 degrees and 23.5 degrees North latitude, within one degree of the latitudes at which similar lightning features were detected by the Galileo spacecraft. The images were taken at different times. The storms' longitudinal separation changes from one image to the next because the winds carrying them blow at different speeds at the two latitudes.

First Day of Fall  

NSDL National Science Digital Library

This activity can be done on the first day of winter, spring, or summer and is intended to help students understand the angle the sun's rays make with the horizon in their location. Students will construct a diagram depicting the sun's rays as they hit the Earth on the first day of the selected season. They will label and measure the angles made from the light of the sun striking the horizons of the various latitudes, and correlate that to the angles of latitude on Earth. This activity can be used as a tool for describing the intensity of the sun on these particular days. The site provides a sample chart and diagram as well as detailed instructions and a list of required materials.

3D Hepatic Cultures Simultaneously Maintain Primary Hepatocyte and Liver Sinusoidal Endothelial Cell Phenotypes  

PubMed Central

Developing in vitro engineered hepatic tissues that exhibit stable phenotype is a major challenge in the field of hepatic tissue engineering. However, the rapid dedifferentiation of hepatic parenchymal (hepatocytes) and non-parenchymal (liver sinusoidal endothelial, LSEC) cell types when removed from their natural environment in vivo remains a major obstacle. The primary goal of this study was to demonstrate that hepatic cells cultured in layered architectures could preserve or potentially enhance liver-specific behavior of both cell types. Primary rat hepatocytes and rat LSECs (rLSECs) were cultured in a layered three-dimensional (3D) configuration. The cell layers were separated by a chitosan-hyaluronic acid polyelectrolyte multilayer (PEM), which served to mimic the Space of Disse. Hepatocytes and rLSECs exhibited several key phenotypic characteristics over a twelve day culture period. Immunostaining for the sinusoidal endothelial 1 antibody (SE-1) demonstrated that rLSECs cultured in the 3D hepatic model maintained this unique feature over twelve days. In contrast, rLSECs cultured in monolayers lost their phenotype within three days. The unique stratified structure of the 3D culture resulted in enhanced heterotypic cell-cell interactions, which led to improvements in hepatocyte functions. Albumin production increased three to six fold in the rLSEC-PEM-Hepatocyte cultures. Only rLSEC-PEM-Hepatocyte cultures exhibited increasing CYP1A1/2 and CYP3A activity. Well-defined bile canaliculi were observed only in the rLSEC-PEM-Hepatocyte cultures. Together, these data suggest that rLSEC-PEM-Hepatocyte cultures are highly suitable models to monitor the transformation of toxins in the liver and their transport out of this organ. In summary, these results indicate that the layered rLSEC-PEM-hepatocyte model, which recapitulates key features of hepatic sinusoids, is a potentially powerful medium for obtaining comprehensive knowledge on liver metabolism, detoxification and signaling pathways in vitro.

Photopatch testing-- a retrospective review using the 1 day and 2 day irradiation protocols.  

PubMed

Photopatch testing is indicated in the investigation of patients with eczematous eruptions, affecting mainly light-exposed sites and in those who give a history of worsening of their condition with sun exposure. 3 different protocols are described by the British Photodermatology Group (Br J Dermatol 1997:136:371-376), 1 of which includes irradiation of allergens 1 day after application and 2 using irradiation of allergens 2 days after application. There is no evidence for superiority of any of these protocols. We reviewed the records of all patients who underwent photopatch testing in Leeds over a 50-month period, who had had the allergens applied in triplicate with 1 set irradiated after 1 day occlusion and another after 2 days. The control was occluded for 2 days. Readings were performed at 2 days and 4 days. 15 of 74 patients photopatch tested during this period had 49 positive results between them. 43 of these were felt to be of current relevance to their clinical problem. 34 of the positive results were indicative of photoallergy. Additional photoallergic reactions were detected following 2 days occlusion and irradiation compared with 1 day occlusion (16 versus 5). In conclusion, our case series suggests that 2 days occlusion before irradiation of allergens is more sensitive at detecting photoallergy. PMID:16487278

Specimen Sample Preservation for Cell and Tissue Cultures  

NASA Technical Reports Server (NTRS)

The era of the International Space Station with its longer duration missions will pose unique challenges to microgravity life sciences research. The Space Station Biological Research Project (SSBRP) is responsible for addressing these challenges and defining the science requirements necessary to conduct life science research on-board the International Space Station. Space Station will support a wide range of cell and tissue culture experiments for durations of 1 to 30 days. Space Shuttle flights to bring experimental samples back to Earth for analyses will only occur every 90 days. Therefore, samples may have to be retained for periods up to 60 days. This presents a new challenge in fresh specimen sample storage for cell biology. Fresh specimen samples are defined as samples that are preserved by means other than fixation and cryopreservation. The challenge of long-term storage of fresh specimen samples includes the need to suspend or inhibit proliferation and metabolism pending return to Earth-based laboratories. With this challenge being unique to space research, there have not been any ground based studies performed to address this issue. It was decided hy SSBRP that experiment support studies to address the following issues were needed: Fixative Solution Management; Media Storage Conditions; Fresh Specimen Sample Storage of Mammalian Cell/Tissue Cultures; Fresh Specimen Sample Storage of Plant Cell/Tissue Cultures; Fresh Specimen Sample Storage of Aquatic Cell/Tissue Cultures; and Fresh Specimen Sample Storage of Microbial Cell/Tissue Cultures. The objective of these studies was to derive a set of conditions and recommendations that can be used in a long duration microgravity environment such as Space Station that will permit extended storage of cell and tissue culture specimens in a state consistent with zero or minimal growth, while at the same time maintaining their stability and viability.

A critical period for functional vestibular development in zebrafish  

NASA Technical Reports Server (NTRS)

We have determined a critical period for vestibular development in zebrafish by using a bioreactor designed by NASA to simulate microgravity for cells in culture. A critical period is defined as the briefest period of time during development when stimulus deprivation results in long lasting or permanent sensory deficits. Zebrafish eggs were collected within 3 hours of being laid and fertilized. In experiment 1, eggs were placed in the bioreactor at 3, 24, 30, 36, 48, or 72 hours postfertilization (hPF) and maintained in the bioreactor until 96 hPF. In experiment 2, eggs were placed in the bioreactor immediately after they were collected and maintained in the bioreactor until 24, 36, 48, 60, 66, 72, or 96 hPF. Beginning at 96 hPF, all larvae had their vestibulo-ocular reflexes (VOR) evaluated once each day for 5 days. Only larvae that hatched from eggs that were placed in the bioreactor before 30 hPF in experiment 1 or removed from the bioreactor later than 66 hPF in experiment 2 had VOR deficits that persisted for at least 5 days. These data suggest a critical period for vestibular development in the zebrafish that begins before 30 hPF and ends after 66 hPF. To confirm this, zebrafish eggs were placed in the bioreactor at 24 hPF and removed at 72 hPF. VORs were evaluated in these larvae once each day for 5 days beginning at 96 hPF. These larvae had VOR deficits that persisted for at least 5 days. In addition, larvae that had been maintained in the bioreactor from 24 to 66 hPF or from 30 to 72 hPF, had only temporary VOR deficits. In a final experiment, zebrafish eggs were placed in the bioreactor at 3 hPF and removed at 96 hPF but the bioreactor was turned off from 24 hPF to 72 hPF. These larvae had normal VORs when they were removed from the bioreactor at 96 hPF. Taken as a whole, these data support the idea that there is a critical period for functional maturation of the zebrafish vestibular system. The developmental period identified includes the timeframe during which the vestibular primary afferent neurons are born, innervate their central and peripheral targets, and remodel their central projections.

First Day in Organic Lab  

NASA Astrophysics Data System (ADS)

This experiment is designed to introduce students to the techniques of reflux, distillation, gas chromatography, and the determination of boiling point and melting point during one lab period. This lab is written so that it can be performed during the first day of lab in organic chemistry, without the students necessarily knowing any organic chemistry. The students answer questions, based upon their observation of the reflux and distillation apparatus, which are already assembled and in operation upon the students' arrival in the lab. Melting points and boiling points are performed by the students on unknown samples, and these unknowns were identified by comparison to a limited list of possibilities. A mixture of alcohols is analyzed by the students. Each student injects a sample under supervision, obtains a chromatogram, and from this, calculates peak area.

Midterm periods of solar filaments  

NASA Astrophysics Data System (ADS)

On the basis of the Carte Synoptique catalogue of solar filaments from March 1919 to December 1989, we measure power spectra of detrended full-disk (FSFNs, latitudinal bands: 0?-90?), low-latitude (LSFNs, latitudinal bands: <50?), and high-latitude (HSFNs, latitudinal bands: ?50?) solar filament numbers by Maximum Entropy Method (MEM) and Continuous wavelet transform to detect midterm periods. It is found as the following: (1) FSFNs and LSFNs have the same midterm periodicity, while HSFNs show a different midrange periodicity. Some periods frequently mentioned in other solar indices are also detected from the solar filament numbers, such as 2-3 year period (quasi-biennial oscillation—QBO), ˜1.7 year, ˜1.3 year, ˜1 year, 150-157 day period (Rieger period), and 6.0-6.4 months (Rieger-type period). These periods are intermittent during considered time span. Some of them are missing in some solar cycles. (2) QBO is detected from total data and most solar cycles of FSFNs, LSFNs, and HSFNs. It may be related to oscillation of magnetic field of solar surface. (3) Approximately 1.3 year period occasionally appears, but ˜1.7 year period is hardly seen. These two periods probably are seasonal effects. (4) Approximately 1 year period is detected from both total data and every solar cycle of FSFNs and LSFNs but hardly detected from HSFNs. It is perhaps connected with sunspot activity. (5) Rieger period of 5.0-5.2 months is detected in total data and even solar cycles of HSFNs. Rieger-type period of 6.0-6.4 months is found in total data and most solar cycles, except cycle 18 of LSFNs and FSFNs. These periods seem to be subharmonics of ˜11 year period.

Fecal contamination in child day care centers: cloth vs paper diapers.  

PubMed Central

OBJECTIVES. Cloth diapers with front closure and all-in-one design were compared with paper diapers containing absorbent gel material for their influence on fecal contamination of the environment in licensed child day care centers. METHODS. One infant room and two toddler rooms in each of four day care centers were monitored for the presence of fecal bacteria. Microbial samples were taken from the play/sleep area, the diaper-changing area, and the hands of the caregivers and the children. Sampling was done twice weekly for two 4-week periods. Each center used either cloth or paper diapers during the first period, changing to the other diaper type during the second period. RESULTS. A total of 1722 samples were cultured, 881 during the first 4 weeks and 841 during the second 4 weeks. The frequency of isolation of fecal organisms ranged from a low of 12% of the total bacteria isolates at a center using cloth diapers, to highs of 46% and 45%, respectively, at a center using first paper and then cloth diapers. Sink faucets and the hands of the caregivers and the children were often contaminated. CONCLUSIONS. Analysis of the results of comparisons between cloth and paper diapers showed no significant difference in the frequency (F = .380, P < .535) or the intensity of fecal contamination in child day care centers.

National immunisation day.  

PubMed

National immunization days (NIDs) are key components of the eradication of polio. On Zambia's polio day in July 1997, 8000 vaccination points were set up around the country, each staffed by 1 nurse and 2 volunteer workers, who worked from thatched huts built for the day, churches, health centers, and house-to-house to reach the target of 2.1 million children. With about half of Zambia's 10 million people living in rural communities poorly served by roads and without main electricity, it was a particular challenge to maintain the cold chain. The cold chain began at Lusaka airport with the arrival of 5.4 million doses of frozen vaccine from Copenhagen, Denmark. The vaccines were then stored in freezers at a central location in Lusaka until they were eventually trucked out to the regional and district centers. The Flying Doctor Service and air force were used, as well as ox and carts, to get vaccines to hard to reach communities. The vaccines arrived at such sites on the NID packed in ice carried over the shoulders of the nurses who delivered them. The NID was deemed successful by the minister of health the morning after it occurred even though some districts ran short of vaccine. Two annual NIDs will continue as long as polio is present in that part of Africa. The global effort to eradicate polio is discussed. PMID:12348370

The maintenance of rat palatal mucosa in organ culture.  

PubMed Central

Palatal mucosa from neonatal rats was maintained under organ culture conditions in a chemically defined medium for periods up to 28 days. The histological state of the cultured palatal mucosa was compared with that of control tissue from growing animals of comparable age. The control tissues showed an increase in epithelial thickness, first noticeable at 17 days. Whilst the general structure of the tissues in organ culture was preserved for the duration of the experiment, some changes in epithelial behavior were evident. There was an increase in epithelial thickness up to 6 days, followed by a reduction in the nucleated cell layer of the epithelium to a thickness comparable with that at the start of the experiment. There was a loss of epithelial glycogen within the first day, with occasional reappearance of patchy and irregular deposits. Whereas the control of epithelial thickness appeared to be restored after 10 days in vitro, disturbances in the maturation of the keratinocytes, manifested as epithelial pearls and dyskeratotic cells, were evident at subsequent stages. Epiboly never occurred. The connective tissue component showed continued development, indicated by an increase in the thickness of collagen fibres. The overall palatal growth seen in vivo did not occur in organ culture. We suggest that the improved maintenance reported is partly the result of explanting tissues in such a way as to minimize trauma, and partly the result of incorporating serum albumin into the chemically defined medium.

Preparation of Triple-Negative Breast Cancer Vaccine through Electrofusion with Day-3 Dendritic Cells  

PubMed Central

Dendritic cells (DCs) are professional antigen-presenting cells (APCs) in human immune system. DC-based tumor vaccine has met with some success in specific malignancies, inclusive of breast cancer. In this study, we electrofused MDA-MB-231 breast cancer cell line with day-3 DCs derived from peripheral blood monocytes, and explored the biological characteristics of fusion vaccine and its anti-tumor effects in vitro. Day-3 mature DCs were generated from day-2 immature DCs by adding cocktails composed of TNF-?, IL-1?, IL-6 and PEG2. Day-3 mature DCs were identified and electofused with breast cancer cells to generate fusion vaccine. Phenotype of fusion cells were identified by fluorescence microscope and flow cytometer. The fusion vaccine was evaluated for T cell proliferation, secretion of IL-12 and IFN-?, and induction of tumor-specific CTL response. Despite differences in morphology, day-3 and day-7 DC expressed similar surface markers. The secretion of IL-12 and IFN-? in fusion vaccine group was much higher than that in the control group. Compared with control group, DC-tumor fusion vaccine could better stimulate the proliferation of allogeneic T lymphocytes and kill more breast cancer cells (MDA-MB-231) in vitro. Day-3 DCs had the same function as the day-7 DCs, but with a shorter culture period. Our findings suggested that day-3 DCs fused with whole apoptotic breast cancer cells could elicit effective specific antitumor T cell responses in vitro and may be developed into a prospective candidate for adoptivet immunotherapy.

Culture evolves  

PubMed Central

Culture pervades human lives and has allowed our species to create niches all around the world and its oceans, in ways quite unlike any other primate. Indeed, our cultural nature appears so distinctive that it is often thought to separate humanity from the rest of nature and the Darwinian forces that shape it. A contrary view arises through the recent discoveries of a diverse range of disciplines, here brought together to illustrate the scope of a burgeoning field of cultural evolution and to facilitate cross-disciplinary fertilization. Each approach emphasizes important linkages between culture and evolutionary biology rather than quarantining one from the other. Recent studies reveal that processes important in cultural transmission are more widespread and significant across the animal kingdom than earlier recognized, with important implications for evolutionary theory. Recent archaeological discoveries have pushed back the origins of human culture to much more ancient times than traditionally thought. These developments suggest previously unidentified continuities between animal and human culture. A third new array of discoveries concerns the later diversification of human cultures, where the operations of Darwinian-like processes are identified, in part, through scientific methods borrowed from biology. Finally, surprising discoveries have been made about the imprint of cultural evolution in the predispositions of human minds for cultural transmission. PMID:21357216

Periods found in heat measurements obtained by calorimetry  

SciTech Connect

During a span of 640 days, a periodicity of 1.5158 +- 0.0008 days was discovered in successive heater equilibria on Calorimeter No. 127. Measurements were taken at 12-h intervals, with occasional changes of exactly 3 or 6 h in the schedule of measurements. This schedule eliminated all other possible periods except a period of 0.150156 days. Periods of 1.519125 and 1.511283 days were discovered in data on the excess length of day as obtained by the US Naval Observatory over a period of 24 y. These two periods could equally well represent periods of 0.150189 and 0.150112 days, since measurements were obtained only once every 24 h. It is suggested that periods observed in sensitive calorimeters and in length of day data may be related. 1 reference, 6 figures, 5 tables.

Cultural Shock  

NSDL National Science Digital Library

The Demos organization in London is a think-tank that produces compelling reports on everything from public space to government spending. This report from October 2010 is by Samuel Jones, and he explores the relationship between the British government and culture and sport. His basic question is: "Why should the state get involved in culture, and if it should, how?" The 154-page report is divided into sections such as "Society and the cultural realm", "Taking the cultural pulse of a nation", and "Evidence of Potential". It's an interesting read, and the paper argues that "cultural policy must focus on the equitable distribution of individuals' cultural capabilities, indicating that this will require thinking anew about what form the structures take, and how they are run."

Changing our culture.  

PubMed

Today, a great challenge of our profession is to envision how we will deliver exemplary neurosurgical care in the future. To accomplish this requires anticipating how economic, political, and societal influences will affect our ability to provide the highest quality of patient care in an arena that will look increasingly different from today's world of medicine. Already, our profession is battling a relentless assault as numerous sectors implement change that impacts us and our community every day. Surviving this requires an effective strategy that will involve significant cultural change. To accomplish this, neurosurgery must take an honest look inward and then commit to being the agents of positive cultural change. Such a path will not be easy but should reap important benefits for all of neurosurgery and our patients. Several practical and proven strategies can help us to realize the rewards of changing our culture. Vital to this process is understanding that effecting behavioral change will increase the likelihood of achieving sustainable cultural change. Innovation and diversity are crucial to encourage and reward when trying to effect meaningful cultural change, while appreciating the power of a "Tipping Point" strategy will also reap significant benefits. As a profession, if we adopt these strategies and tactics we can lead our profession to proceed in improvement, and as individuals we can use the spirit that drove us into neurosurgery to become the agents of an enduring and meaningful cultural change that will benefit our patients and us.

Effects of isobutyl 2-cyanoacrylate polymer on cultured cells derived from murine cerebral microvessels.  

PubMed

The initial and delayed effects of isobutyl 2-cyanoacrylate (IBCA) polymer on cells cultured from the wall of mouse cerebral microvessels were examined using a simple cytotoxicity assay. Cell cultured media were conditioned by exposure to IBCA polymer for 24-hr periods over the 15 days following polymerization and the media were then added to confluent endothelial or smooth muscle cell monolayers. The resulting cell detachment was assessed as a measure of cytotoxicity. The results indicated that immediately or a few days after polymerization and at approximately 12-13 days after polymerization, IBCA released material(s) that caused significant cell detachment from cell monolayers. This finding may explain some of the observed toxic effects of IBCA, particularly on vascular lesions within the brain. This simple bioassay may be used to study early and delayed effects of other potential embolotherapy materials on components of the blood vessel wall. PMID:20702356

The objective of this study was to explore drug use in Mexican rural communities and its relationship to social cohesion, cultural identity, migration, and transculturation. Community models typification was used, considering cohesion as the central point of analysis. The research was conducted during 15-day periods in each of nine communities during 1991. Both documentary and ethnographic techniques were used to gather information. Results indicated that rural communities where there was little or no drug use among its members show more social cohesion, cultural identity, and community links consolidation, and more capacity for integrating change. This pattern is most apparent among young community members who have had more contact with the outer world (drug trafficking, North American culture, and Mexican urban culture). PMID:12117067

EDMs are motions introduced by Members of Parliament (MPs) that are generally not debated but are rather used to draw attention to a particular issue or gather support for it by having other MPs add their signatures. Despite this, EDMs are often noted by the press, and some use them to interpret opinions on wider issues. Users can search the database of the 1997/9 Session by EDM number or description or browse the current list, which displays Title, Primary Sponsor, and the Number of Signatures. Parliament is currently on summer recess until October 19 (with the exception of a brief special session to introduce new security measures for Northern Ireland), but when it is in session, the database will be updated daily.

A Single-Culture Bioprocess of Methanothermobacter thermautotrophicus to Upgrade Digester Biogas by CO2-to-CH4 Conversion with H2  

PubMed Central

We optimized and tested a postbioprocessing step with a single-culture archaeon to upgrade biogas (i.e., increase methane content) from anaerobic digesters via conversion of CO2 into CH4 by feeding H2 gas. We optimized a culture of the thermophilic methanogen Methanothermobacter thermautotrophicus using: (1) a synthetic H2/CO2 mixture; (2) the same mixture with pressurization; (3) a synthetic biogas with different CH4 contents and H2; and (4) an industrial, untreated biogas and H2. A laboratory culture with a robust growth (dry weight of 6.4–7.4?g/L; OD600 of 13.6–15.4), a volumetric methane production rate of 21?L/L culture-day, and a H2 conversion efficiency of 89% was moved to an industrial anaerobic digester facility, where it was restarted and fed untreated biogas with a methane content of ~70% at a rate such that CO2 was in excess of the stoichiometric requirements in relation to H2. Over an 8-day operating period, the dry weight of the culture initially decreased slightly before stabilizing at an elevated level of ~8?g/L to achieve a volumetric methane production rate of 21?L/L culture-day and a H2 conversion efficiency of 62%. While some microbial contamination of the culture was observed via microscopy, it did not affect the methane production rate of the culture. PMID:24194675

It will not come as a surprise to anyone who has visited the British Isles to learn that out of the $42.2 billion, Britons spent $19.2 billion, and made almost one in three chocolate purchases, trumping all of the world's nations. The report from Datamonitor also noted that tastes in chocolate vary widely across Europe, noting that, "The French prefer simplicity and purity of taste, without additional flavors and with little sugar, while Italian tastes are geared toward the more indulgent and sophisticated end of the market." Additionally, the report also indicates that the United States continues to dominate the global chocolate confectionary market, with Americans spending $2.4 billion on boxed chocolates alone in 2001.The first link is to the recent report on global chocolate sales and consumption released by the Datamonitor group.

Biodegradation of Palm Kernel Cake by Cellulolytic and Hemicellulolytic Bacterial Cultures through Solid State Fermentation  

PubMed Central

Four cellulolytic and hemicellulolytic bacterial cultures were purchased from the Leibniz Institute DSMZ-German Collection of Microorganisms and Cell Culture (DSMZ) and the American Type Culture Collection (ATCC). Two experiments were conducted; the objective of the first experiment was to determine the optimum time period required for solid state fermentation (SSF) of palm kernel cake (PKC), whereas the objective of the second experiment was to investigate the effect of combinations of these cellulolytic and hemicellulolytic bacteria on the nutritive quality of the PKC. In the first experiment, the SSF was lasted for 12 days with inoculum size of 10% (v/w) on different PKC to moisture ratios. In the second experiment, fifteen combinations were created among the four microbes with one untreated PKC as a control. The SSF lasted for 9 days, and the samples were autoclaved, dried, and analyzed for proximate analysis. Results showed that bacterial cultures produced high enzymes activities at the 4th day of SSF, whereas their abilities to produce enzymes tended to be decreased to reach zero at the 8th day of SSF. Findings in the second experiment showed that hemicellulose and cellulose was significantly (P < 0.05) decreased, whereas the amount of reducing sugars were significantly (P < 0.05) increased in the fermented PKC (FPKC) compared with untreated PKC.

Elicitors like cadmium chloride, aluminium chloride and chitosan, precursors such as cholesterol, mevalonic acid and squalene were examined. Maximum total withanolides detected [withanolide A (7606.75 mg), withanolide B (4826.05 mg), withaferin A (3732.81 mg), withanone (6538.65 mg), 12 deoxy withanstramonolide (3176.63 mg), withanoside IV (2623.21 mg) and withanoside V (2861.18 mg)] were achieved in the combined treatment of chitosan (100 mg/l) and squalene (6 mM) along with 1 mg/l picloram, 0.5 mg/l KN, 200 mg/l L-glutamine and 5% sucrose in culture at 4 h and 48 h exposure times respectively on 28th day of culture in bioreactor. We obtained higher concentrations of total withanolides in shake-flask culture (2.13-fold) as well as bioreactor (1.66-fold) when compared to control treatments. This optimized protocol can be utilized for commercial level production of withanolides from suspension culture using industrial bioreactors in a short culture period. PMID:25089711

Maximum total withanolides detected [withanolide A (7606.75 mg), withanolide B (4826.05 mg), withaferin A (3732.81 mg), withanone (6538.65 mg), 12 deoxy withanstramonolide (3176.63 mg), withanoside IV (2623.21 mg) and withanoside V (2861.18 mg)] were achieved in the combined treatment of chitosan (100 mg/l) and squalene (6 mM) along with 1 mg/l picloram, 0.5 mg/l KN, 200 mg/l L-glutamine and 5% sucrose in culture at 4 h and 48 h exposure times respectively on 28th day of culture in bioreactor. We obtained higher concentrations of total withanolides in shake-flask culture (2.13-fold) as well as bioreactor (1.66-fold) when compared to control treatments. This optimized protocol can be utilized for commercial level production of withanolides from suspension culture using industrial bioreactors in a short culture period. PMID:25089711

Development of a serum-free defined system employing growth factors for preantral follicle culture.  

PubMed

This study was conducted to evaluate if mouse preantral follicles can yield developmentally competent oocytes following culture in serum-free, defined medium. Donor follicles were obtained from 14-day-old B6CBAF1 mice, and cultured in ?-MEM-Glutamax medium. The replacement of fetal bovine serum with knockout serum replacement (KSR) did not significantly reduce follicle growth or oocyte maturation in vitro, although it significantly reduced the development of oocytes after activation. Regardless of the replacement medium, follicle growth was not influenced by the addition of leukemia inhibitory factor (LIF). The addition of 100 ng/ml stem cell factor (SCF) to the KSR-supplemented serum-free medium significantly stimulated follicle development, which further improved blastocyst formation after oocyte activation. On Day 3 of culture, a significant increase in Bmp7 expression was detected in the SCF-containing medium compared with the serum-containing medium, whereas Gdf9 and Amh were increased in the serum-containing medium. A significant increase in estradiol production was detected under serum-free conditions, but minimal progesterone secretion was detected throughout the culture period. In conclusion, serum-free media can be used to optimize ovarian follicle cultures, and the addition of SCF is beneficial for deriving developmentally competent oocytes through follicle culture.

On the period of HR 1362  

SciTech Connect

Photoelectric UBV observations, made in 1981 and 1982, of the active star HR 1362, are presented. A period analysis reveals many (all greater than 100 days) probable periods because of the large gaps in the data. If the most probable period around 330 d is true and represents the rotation period, as it does in all other active stars, then HR 1362 would be an extreme case of slow rotation. 11 refs.

[Comparative characterization of mesenchymal bone marrow stromal cells at early and late stages of culturing].  

PubMed

The mesenchymal stromal cell is a multipotent precursor of osteoblasts, adipocytes, and some other cell types. In this study, a comparative analysis of cultured mesenchymal stromal cells from the rat bone marrow at the early and late stages of subculturing has been performed using molecular genetic and cytological methods. The culture has undergone 11 passages during 140 days. Upon long-term culturing, the mesenchymal stromal cells have proved to lose their potential for adipogenic differentiation but preserve the potential for osteogenesis. Morphological characters typical of osteogenic differentiation can be observed at the earlier stages of culturing (passages 1-4) but disappear at later stages (passages 9-11), despite mineralization of the extracellular matrix and the expression of osteogenic differentiation markers. A comparative analysis of the proliferation potential of stromal cells has shown that differences in the period of cell population doubling at the early and later stages of culturing are insignificant. An almost complete arrest of cell growth has been observed in the middle of the culture period (passages 5 and 6). PMID:18946989

[Explant culture of Trifolium pratense L].  

PubMed

The red cloverl seems to be a prospective source of flavonoids and isoflavonoids with phytoestrogenic activity. Young seedlings of four different varieties of Trifolium pratense L. were employed to derive callus and suspension cultures. The optimal medium for cultivation is Gamborg's cultivating medium with an addition of 2 mg x l(-1) of 2,4-dichlorphenoxyacetic acid and 2 mg x l(-1) of 6-benzylaminopurine. On the basis of growth and production characteristics, subcultivating intervals of 29 to 43 days in callus culture and 16 to 23 days in suspension culture were determined. TLC and HPLC revealed that the explant culture of Trifolium pratense L. contains the isoflavonoid formononetin. PMID:16502812

Clinical profile of bronchiolitis in infants younger than 90 days in Saudi Arabia  

PubMed Central

Background: Bronchiolitis is a self-limiting disease of children caused by viral infections of the small airways with a wide spectrum of illness severity. Search of the literature reveals a need for refinement of criteria for testing for concomitant severe bacterial infections as well as appropriate therapeutic interventions for patients <90-day-old diagnosed with clinical bronchiolitis. We believe that a better understanding of the disease spectrum will help optimize health-care delivery to these patients. Aims: The aim of this study was to determine the clinical profile at presentation, disease course and outcome of bronchiolitis in <3-month-old infants who presented to our Pediatric Emergency Department (PED) during one disease season. Settings: Retrospective chart review during one bronchiolitis season, from November 1, 2011 to April 20, 2012. Subjects: All <90-day-old infants presenting with clinical bronchiolitis presenting to Urban PED of a tertiary care university hospital during one bronchiolitis season. Materials and Methods: A retrospective chart review based on computer records of all emergency department visits of infants less than 90 days with a clinical diagnosis of bronchiolitis, covering the period between November 1, 2011 and April 30, 2012. Results: Out of the total of 1895 infants <90 days of age, 141 had a clinical diagnosis of bronchiolitis and 35 needed admission to hospital. Blood for culture was obtained from 47 infants, urine for culture was obtained from 46 infants and cerebrospinal fluid for culture was obtained from eight infants. One case of bacteremia was documented, but this was found to be a contaminant. No cases of meningitis occurred among these infants. However, one infant had a positive urine culture consistent with infection (Escherichia coli). Conclusion: Based on the results, it can be conclude that the risk of bacteremia or meningitis among infants <90 days of age with fever and bronchiolitis is low. The risk of urinary tract infection in this age group is also low, but it is higher than the risk for meningitis or bacteremia. Our data for admission and treatment guidelines are similar to those published from other countries. PMID:24550632

Periodicity Analysis of SMMF in Solar Maximum and Minimum  

NASA Astrophysics Data System (ADS)

Using the data observed by Wilcox Solar Observatory from 1975 to 2010,the short periodicity of the solar mean magnetic field (SMMF)in solar maximum and minimum is analyzed. The result shows that SMMF has main periods about 9 days, 13.5 days, and 27 days. During the solar maximum, the SMMF has the most dominant period near 27 days. However, in solar minimum, the 13.5-day periodicity is most significant except in 1984-1986. These results show that the solar active region distribution in the solar maximum is quite different from that in solar minimum.

How to use... blood cultures.  

PubMed

Positive blood culture is the gold standard for diagnosing bacteraemia and fungaemia, yet there is significant variability in aspects of performing and interpreting the test in children and neonates. Processing a blood culture can take several days, and includes use of semi-automated incubation with growth detection and a broad range of laboratory techniques such as Gram staining, phenotypic or molecular identification and antimicrobial susceptibility testing on a cultured isolate. Sensitivity and specificity of a blood culture and time-to-positivity depend on a number of factors related to host/pathogen interaction, collection and transport of the specimen to the laboratory and methods employed to process the specimen. Interpretation of a positive result relies on correlation of the identity of the cultured microorganism with the clinical assessment of the child. PMID:24334340

The Two Cultures in Psychiatry.  

PubMed

The division between the two cultures of the literary and scientific worlds is considered, as is the division between the two cultures of humanism and somaticism. The development of psychiatric thought important to this latter dichotomy is described through the Age of Enlightenment, the Romantic Movement and the New Enlightenment. The two cultures of our present literary and scientific milieux are equated with the romanticism and somaticism of the past. The development of two cultures in psychiatry is traced, beginning with Freud's attempt to combine science and romanticism, to the present day where one finds some degree of convergence between the somatic and psychoanalytic approaches. Criteria are presented for a greater union of the two cultures in psychiatry. PMID:20328284

Paleomicrobiology: Revealing Fecal Microbiomes of Ancient Indigenous Cultures  

PubMed Central

Coprolites are fossilized feces that can be used to provide information on the composition of the intestinal microbiota and, as we show, possibly on diet. We analyzed human coprolites from the Huecoid and Saladoid cultures from a settlement on Vieques Island, Puerto Rico. While more is known about the Saladoid culture, it is believed that both societies co-existed on this island approximately from 5 to 1170 AD. By extracting DNA from the coprolites, followed by metagenomic characterization, we show that both cultures can be distinguished from each other on the basis of their bacterial and fungal gut microbiomes. In addition, we show that parasite loads were heavy and also culturally distinct. Huecoid coprolites were characterized by maize and Basidiomycetes sequences, suggesting that these were important components of their diet. Saladoid coprolite samples harbored sequences associated with fish parasites, suggesting that raw fish was a substantial component of their diet. The present study shows that ancient DNA is not entirely degraded in humid, tropical environments, and that dietary and/or host genetic differences in ancient populations may be reflected in the composition of their gut microbiome. This further supports the hypothesis that the two ancient cultures studied were distinct, and that they retained distinct technological/cultural differences during an extended period of close proximity and peaceful co-existence. The two populations seemed to form the later-day Taínos, the Amerindians present at the point of Columbian contact. Importantly, our data suggest that paleomicrobiomics can be a powerful tool to assess cultural differences between ancient populations. PMID:25207979

Induction and analysis of the alkaloid mitragynine content of a Mitragyna speciosa suspension culture system upon elicitation and precursor feeding.  

PubMed

This study aimed to determine the effects of different concentrations and combinations of the phytohormones 2,4-dichlorophenoxy acetic acid (2,4-D), kinetin, 6-benzylaminopurine (BAP), and 1-naphthaleneacetic acid (NAA) on callus induction and to demonstrate the role of elicitors and exogenous precursors on the production of mitragynine in a Mitragyna speciosa suspension culture. The best callus induction was achieved from petiole explants cultured on WPM that was supplemented with 4?mg?L?¹ 2,4-D (70.83%). Calli were transferred to liquid media and agitated on rotary shakers to establish Mitragyna speciosa cell suspension cultures. The optimum settled cell volume was achieved in the presence of WPM that contained 3?mg?L?¹ 2,4-D and 3% sucrose (9.47 ± 0.4667?mL). The treatment of cultures with different concentrations of yeast extract and salicylic acid for different inoculation periods revealed that the highest mitragynine content as determined by HPLC was achieved from the culture treated with 250?mg?L?¹ yeast extract (9.275 ± 0.082?mg?L?¹) that was harvested on day 6 of culturing; salicylic acid showed low mitragynine content in all concentrations used. Tryptophan and loganin were used as exogenous precursors; the highest level of mitragynine production was achieved in cultures treated with 3? ?M tryptophan and harvested at 6 days (13.226 ± 1.98?mg?L?¹).

70 Days of Jupiter Winds  

NASA Technical Reports Server (NTRS)

This global movie of 70 days of Jupiter's cloud movements photographed by NASA's Cassini spacecraft shows that zones of eastward and westward winds cover the planet virtually from pole to pole.

Cassini's narrow-angle camera captured the images of Jupiter's atmosphere from October 1 to December 9, 2000, in the near-infrared region of the spectrum. The view here is a cylindrical projection centered in the planet's equator.

The movie allows tracking of individual storms' movements in the familiar zonal bands of the lower latitudes, in the swirling turbulence around the Great Red Spot and in the high latitudes where still images show chaotic mottling instead of stripes.

Cassini collected images of Jupiter for months before and after it passed the planet on December 30, 2000. Six or more images of the planet in each of several spectral filters were taken at evenly spaced intervals over the course of Jupiter's 10-hour rotation period. The entire sequence was repeated generally every other Jupiter rotation, yielding views of every sector of the planet at least once every 20 hours.

The images used for the movie shown here were taken every 20 hours through a filter centered at a wavelength of 756 nanometers, where there are almost no absorptions in the planet's atmosphere. Six images covering each rotation were mosaiced together to form a cylindrical map extending from 75 degrees north to 75 degrees south in latitude and covering 360 degrees in longitude. The movie consists of 84 such maps, spanning 70Earth days in time or 168 Jupiter rotations.

Three dimensional culture of pineal cell aggregates: a model of cell-cell co-operation.  

PubMed

Three dimensional (3-D) cultures of pineal cell aggregates were obtained by constant gyratory shaking the heterogenous cell populations, obtained from the rat pineals, in the DMEM (Dulbecco's modified Eagle's medium). Within 4 days, the pineal cells became organized into a tissue like configuration appearing as a compact ball, evidenced by the scanning electron microscopy. The 3-D aggregates seemed to be mainly composed of pinealocytes (round-oval cells), glial (elongated cells) and other unknown cells. The heterogenous cells were separated by intercellular spaces. The ultrastructural characteristics revealed by transmission electron microscopy exhibited the presence of granular lysosomes, typical of pinealocytes actively involved in the secretion. These pineal cell aggregates secreted melatonin and other indole amines i.e. 5-methoxytryptamine (5-MT), indole acetic acid (IAA), 5-methoxy-3-indole acetic acid (5-MIAA), tryptophol (TOL) and 5-methoxytryptophol (5-MTL) in the culture medium, indicating the functional aspect of pinealocytes. The 3-D aggregates cultures had advantages over the pineal monolayer cultures as, after 4 days of culture, the amounts of indole amines secreted by 3-D aggregates were higher than those secreted by monolayer cultures. Besides, the 3-D aggregates remained functional till 24 days in the gyratory culture conditions. In the continuous perifusion system, the 3-D aggregates secreted melatonin while challanged with isoproterenol. This 3-D model of pineal cell aggregates might be useful, in future, to perform other kinetic studies of the release of indole amines in perifusion experiments as this system allows the maintenance of pineal cells for a long period of time.

47 the avian chorio-allantoic membrane: a suitable short-term culture system for bovine ovarian tissue.  

PubMed

Successful cryopreservation of bovine ovarian tissue holds enormous potential for long-term maintenance of female gametes to preserve genetic diversity by tissue banking. Traditionally, in vitro culture followed by histopathological examination has been used to assess the post-thaw viability of cryopreserved tissues. Recently, in ovo transplantation of mammalian tissues on the chorio-allantoic membrane (CAM) of a growing chicken embryo has emerged as an alternative method for short-term culture. The purpose of this experiment was to compare CAM culture of bovine ovarian tissue over a 5-day period with the in vitro culture system. Fertilized White Leghorn eggs were incubated at 37°C and 62% relative humidity. A window (1×2cm) was cut into the eggshell on Day 3 of incubation. Ovaries were retrieved from a local abattoir and brought to the laboratory within 6h. Ovarian cortex pieces (1-2mm(3)) were randomly assigned to control, CAM-culture, or in vitro-culture groups. Control-group tissues were fixed immediately in 4% paraformaldehyde. The CAM was traumatized on Day 10 of incubation to expose the underlying blood vessels, and tissue pieces were grafted at the site (one graft per egg). For in vitro culture, the ovarian cortex pieces were placed on tissue culture inserts within 6-well plates containing TCM199 with 1% insulin-transferrin-selenium, 100 mIUmL(-1) of FSH, 100IUmL(-1) of penicillin, and 50?gmL(-1) of streptomycin and incubated at 38°C in 5% CO2. Ovarian tissues from the CAM and in vitro culture group were removed on Day 1, 3, and 5 of grafting/culture, fixed, embedded in paraffin, sectioned at 5?m, stained with hematoxylin-eosin, and analysed under a light microscope. The numbers of normal and degenerated follicles (indicating follicle survival) and number of blood vessels containing bovine and avian red blood cells (indicating angiogenesis) were counted using standard stereological procedures. All ovarian cortex grafts from surviving chick embryos showed adhesion with the CAM and a marked neo-vascularization in the graft areas. Gross and histological examination revealed the circulation of avian blood cells in ovarian stromal vessels with a concomitant decrease in the number of bovine blood vessels over the incubation period. Total follicle densities (mean ± s.e.m.) on Day 1, 3, and 5 were 13.3±5.9, 27.9±6.7, and 36.9±7.3 in the in vitro-cultured group and 36.7±13.0, 73.6±24.0, and 44.02±12.67 per millimeter cubed in the CAM-cultured group, respectively. Overall, total follicle density was higher in the CAM-cultured group (P<0.05). Likewise, the normal follicle densities on Day 1, 3, and 5 were 10.4±4.9, 15.5±3.6, and 20.7±6.3 in the in vitro-cultured group and 30.5±8.5, 45.7±18.4, and 22.7±7.3 per millimeter cubed in the CAM-cultured group (P>0.05). In conclusion, in ovo CAM grafting system was as successful as the in vitro-culture system and may be considered an acceptable alternative to the traditional in vitro-culture system for bovine ovarian tissue.

Effect of Clarias gariepinus cultured in contaminated water on rats.  

PubMed

In this study, African Catfish (Clarias gariepinus) were cultured in water contaminated with phthalate, benzene and cyclohexane (10 microg/mL), respectively, over a period of 65 days. They were, thereafter, used as protein source to formulate feed for albino rats (Wistar strain) for 28 days. The weights of the body and selected tissues of the rats were monitored and standard enzyme assays were conducted for some enzymes in the serum. Results showed that rats in cyclohexane group gained 58% whereas the control group gained 46% of body weight. Liver weight (absolute and relative) of test rats were found to be significantly lower than that of control (p < .05). Enzyme activity of serum of test rats was found to be significantly higher than that of control (p < .05). Experimental evidence suggests leakage of enzymes from the liver to the serum, thus the elevated serum enzyme activity and that the contaminants may damage the liver. PMID:19887379

Clonal distribution of osteoprogenitor cells in cultured chick periostea: Functional relationship to bone formation  

SciTech Connect

Folded explants of periosteum from embryonic chick calvaria form bone-like tissue when grown in the presence of ascorbic acid, organic phosphate, and dexamethasone. All osteoblast-like cells in these cultures arise de novo by differentiation of osteoprogenitor cells present in the periosteum. To study the spatial and functional relationships between bone formation and osteoprogenitor cells, cultures were continuously labeled with (3H)thymidine for periods of 1-5 days. Radioautographs of serial 2-microns plastic sections stained for alkaline phosphatase (AP) showed maximal labeling of 30% of fibroblastic (AP-negative) cells by 3 days while osteogenic cells (AP-positive) exhibited over 95% labeling by 5 days. No differential shifts in labeling indices, grain count histograms of fibroblastic and osteogenic cells or numbers of AP-positive cells were observed, indicating no significant recruitment of cells from the fibroblastic to the osteogenic compartment. Despite the continuous presence of (3H)thymidine, less than 35% of both osteoblasts and osteocytes were labeled at 5 days, indicating that only one-third of the osteoprogenitor cells had cycled prior to differentiation. Spatial clustering of (3H)thymidine-labeled cells was measured by computer-assisted morphometry and application of the Poisson distribution to assess contagion. Cluster size and number of labeled cells per cluster did not vary between 1-3 days, but the number of clusters increased 20-fold between Day 1 and Day 3. Three-dimensional reconstruction from serial sections showed that clusters formed long, tubular arrays of osteogenic cells up to eight cells in length and located within 2-3 cell layers from the bone surface. Selective killing of S-phase cells with two pulse labels of high specific activity (3H)thymidine at 1 and 2 days of culture completely blocked bone formation.

Production of 5-hydroxy-7-methoxy-4-methylphthalide in a culture of Penicillium crustosum.  

PubMed

The chemical reactions carried out by microorganisms have been used as a tool in modern chemistry. This paper reports the production of mycophenolic acid and a new phthalide by the endophytic fungus Penicillium crustosum obtained from coffee seeds. The fungus was cultivated in a liquid medium for a period of seven days and after that the culture medium was divided into four treatments: A, B, C and D, to which different organic substances were added. Treatment A was maintained as the control to evaluate the occurrence of biotransformation. Organic acids were added to the culture media of treatments B (ferulic and quinic acids) and C [cinnamic and 3,4-(methylenedioxy) cinnamic acids], and caffeine was added in the treatment D. All these organic compounds were dissolved in DMSO, and the fermentation was maintained for more 13 days, totalizing 20 days. Mycophenolic acid was isolated from the culture with no added acids (treatment A). Mycophenolic acid and a new phthalide, 5-hydroxy-7-methoxy-4-methylphthalide were isolated from treatments B and C, and mycophenolic acid and caffeine (added to the culture medium) were isolated from treatment D. The structures were determined by NMR techniques and confirmed by MS and MS/MS techniques. PMID:23780307

Biomass production and nutrient removal potential of water hyacinth cultured in sewage effluent  

SciTech Connect

Growth and nutrient uptake of water hyacinth (Eichhornia crassipes (Mart Solms)) cultured in sewage effluent were measured over a period of one year in a prototype wastewater treatment system which has been in operation at Walt Disney World near Orlando, Florida. Annual productivity of water hyacinth cultured in primary sewage effluent (Channel II) was found to be in the range of 5 to 27 g dry wt/m/sup 2/ day (23.6 dry tons/acre yr). Average growth rate during the months of May through October 1982 for hyacinth cultured in Channel II (primary sewage effluent) and Channel I (treated primary sewage effluent leaving Channel II) was about 16 g dry wt/m/sup 2/ (27 dry tons/acre yr), compared to the growth rate of 13 g dry wt/m/sup 2/ (22 dry tons/acre yr) for hyacinths cultured in secondary sewage effluent. Plants cultured in secondary sewage effluent generally had longer roots than the plants cultured in primary sewage effluent. A significant relationship was observed between the growth rate of hyacinth and the solar radiation. N and P concentration of the plant tissue were higher in the hyacinths cultured during winter months compared to the plants grown in summer months. Average N and P concentration of the plants cultured im primary sewage effluent were found to be 3.7% N and 0.94% P, respectively, while the plants cultured in secondary sewage effluent had a total N and P content of 2.8% N and 0.79% P. Nutrient ratios of the major plant nurtrients were found to be approximately the same as the nutrient ratios in the sewage effluent. Annual N and P uptake rates of hyacinth cultured in sewage effluent were found to be in the range of 1176 to 1193 kg N/ha yr and 321 to 387 kg P/ha yr, respectively.

Phenotypic Characterization of Prostate Cancer LNCaP Cells Cultured within a Bioengineered Microenvironment  

PubMed Central

Biophysical and biochemical properties of the microenvironment regulate cellular responses such as growth, differentiation, morphogenesis and migration in normal and cancer cells. Since two-dimensional (2D) cultures lack the essential characteristics of the native cellular microenvironment, three-dimensional (3D) cultures have been developed to better mimic the natural extracellular matrix. To date, 3D culture systems have relied mostly on collagen and Matrigel™ hydrogels, allowing only limited control over matrix stiffness, proteolytic degradability, and ligand density. In contrast, bioengineered hydrogels allow us to independently tune and systematically investigate the influence of these parameters on cell growth and differentiation. In this study, polyethylene glycol (PEG) hydrogels, functionalized with the Arginine-glycine-aspartic acid (RGD) motifs, common cell-binding motifs in extracellular matrix proteins, and matrix metalloproteinase (MMP) cleavage sites, were characterized regarding their stiffness, diffusive properties, and ability to support growth of androgen-dependent LNCaP prostate cancer cells. We found that the mechanical properties modulated the growth kinetics of LNCaP cells in the PEG hydrogel. At culture periods of 28 days, LNCaP cells underwent morphogenic changes, forming tumor-like structures in 3D culture, with hypoxic and apoptotic cores. We further compared protein and gene expression levels between 3D and 2D cultures upon stimulation with the synthetic androgen R1881. Interestingly, the kinetics of R1881 stimulated androgen receptor (AR) nuclear translocation differed between 2D and 3D cultures when observed by immunofluorescent staining. Furthermore, microarray studies revealed that changes in expression levels of androgen responsive genes upon R1881 treatment differed greatly between 2D and 3D cultures. Taken together, culturing LNCaP cells in the tunable PEG hydrogels reveals differences in the cellular responses to androgen stimulation between the 2D and 3D environments. Therefore, we suggest that the presented 3D culture system represents a powerful tool for high throughput prostate cancer drug testing that recapitulates tumor microenvironment. PMID:22957009

Early Detection of Mycobacteria Using a Novel Hydrogel Culture Method  

PubMed Central

Background Early laboratory detection of Mycobacterium tuberculosis is crucial for controlling tuberculosis. We developed a hydrogel mycobacterial culture method that retains the advantages of both solid and liquid methods in terms of speed, cost, and efficiency. Methods Mycobacterium bovis bacillus Calmette-Guérin (BCG) suspensions and 200 acid-fast bacilli (AFB)-positive clinical specimens were inoculated in Middlebrook 7H9 liquid media (Becton-Dickinson and Company, USA) and mixed with 75 µL of 9-fluorenylmethoxycarbonyl (Fmoc)-Phe-Phe-OH hydrogel stock solution in an Eppendorf tube just before culture incubation. The mixtures were cultured at 37? for as long as 14 days to monitor culture status. Results The number of M. bovis BCG increased with time. For 200 AFB smear-positive specimens, 155 of 158 conventional culture-positive specimens and 4 culture-negative or contaminated specimens yielded positive cultures within 14 days. For 128 specimens positive with the liquid culture method, the time to positive culture using the hydrogel method (mean, 12.6 days; range, 7 to 14 days) was significantly shorter than that for conventional liquid culture (mean, 16.2 days; range, 6 to 31 days; P<0.0001). Conclusions The hydrogel scaffold culture system is useful for timely, economical, and efficient detection of mycobacteria in clinical specimens. PMID:24422192

Safety of high doses of Propionibacterium freudenreichii ET-3 culture in healthy adult subjects.  

PubMed

Propionibacterium freudenreichii ET-3 (7025) culture, a cell-free product of whey fermentation by P. freudenreichii ET-3, has been shown to promote the growth of Bifidobacteria through the action of 1,4-dihydroxy-2-naphthoic acid (DHNA). Here we report the results of two clinical studies designed to evaluate the safety of high doses of P. freudenreichii ET-3 culture medium. Study 1 had a randomized, double-blind, crossover design. Ten healthy male and four healthy female subjects received 45 tablets of either P. freudenreichii ET-3 culture medium (total daily intake of 3g solid content and 283.5?g of DHNA; active group) or placebo (unfermented product) during two 1-week supplementation periods separated by a 4-week washout period. In Study 2, 11 healthy men took four tablets of P. freudenreichii ET-3 culture medium per day (total daily intake of 0.267g solid content and 22.5?g of DHNA) for a period of 13weeks. In both studies, hematological, clinical chemistry, and urinary parameters were measured before and after each supplementation period and gastrointestinal symptoms were assessed by questionnaire. In Study 1, there were no statistically significant differences between placebo and active supplementation periods in any measured parameter and the incidence of gastrointestinal symptoms were similar between groups. In Study 2, total protein, white blood cell count, hemoglobin, and mean corpuscular hemoglobin concentration decreased significantly from baseline and mean corpuscular volume and urine pH increased from baseline. The changes in hematological parameters were deemed not to be due to P. freudenreichii ET-3 culture medium supplementation given that all parameters remained within normal ranges and were not consistent with any clinically meaningful effect.

Novel tissue culture method: skeletal muscle implantation under gizzard serous membrane of a chick.  

PubMed

A novel method for a long-term culture of skeletal muscle is described. Skeletal muscle pieces from young chicks were implanted under the gizzard serous membrane of the same chicks. Following muscle degeneration, new well-grouped muscle fibers were formed by the fusion of myocytes that differentiated from surviving satellite cells, and the regenerated muscle tissues were maintained in position for longer than 60 days. The implants were in the vital circulatory system, receiving trophic and oxygen supplies, and are completely free from motor nerve innervation and cell contamination with exogenous muscle cells, not as in intra-muscular implantation. Therefore, this tissue culture method should be useful for studying skeletal muscle regeneration and maturation over a long period. Furthermore, osteogenesis and feather development were also found in the implants of embryonic limbs by using the same method. These observations showed that not only skeletal muscle tissues but also other tissues could be cultured under the gizzard serous membrane. PMID:10766970

Rat retina shows robust circadian expression of clock and clock output genes in explant culture  

PubMed Central

Purpose Circadian rhythms are central to vision and retinal physiology. A circadian clock located within the retina controls various rhythmic processes including melatonin synthesis in photoreceptors. In the present study, we evaluated the rhythmic expression of clock genes and clock output genes in retinal explants maintained for several days in darkness. Methods Retinas were dissected from Wistar rats, either wild-type or from the Per1-luciferase transgenic line housed under a daily 12 h:12 h light-dark cycle (LD12/12), and put in culture at zeitgeber time (ZT) 12 on semipermeable membranes. Explants from wild-type rats were collected every 4 h over 3 days, and total RNA was extracted, quantified, and reverse transcribed. Gene expression was assessed with quantitative PCR, and the periodicity of the relative mRNA amounts was assessed with nonlinear least squares fitting to sine wave functions. Bioluminescence in explants from Per1-luciferase rats was monitored for several days under three different culture protocols. Results Rhythmic expression was found for all studied clock genes and for clock downstream targets such as c-fos and arylalkylamine N-acetyltransferase (Aanat) genes. Clock and output genes cycled with relatively similar periods and acrophases (peaks of expression during subjective night, except c-fos, which peaked around the end of the subjective day). Data for Per1 were confirmed with bioluminescence monitoring, which also permitted culture conditions to be optimized to study the retina clock. Conclusions Our work shows the free-running expression profile of multiple clock genes and potential clock targets in mammalian retinal explants. This research further strengthens the notion that the retina contains a self-sustained oscillator that can be functionally characterized in organotypic culture. PMID:24940028

Polyamines and flowering in thin layer tobacco tissue cultures. III. Kinetics of uptake and binding of labelled spermidine  

SciTech Connect

/sup 14/C-labelled spermidine (Spd) was supplied to thin layer tobacco tissue cultures growing on Murashige-Skoog medium + 1 ..mu..M NAA and kinetin. Such cultures produce only flower buds, which become obvious after about 15 days. Spd is taken up rapidly at a rate sustained throughout the culture period. Considerable binding of Spd to TCA - precipitable material occurs by day 2 of culture; it increases to a maximum on day 4 and declines by day 10, shortly before flowering. About 80% of the TCA - precipitable label remains in the form of Spd, 12% shows up as putrescine and 3% as spermine. Differential centrifugation revealed binding of Spd to various cell organelles. DNase, RNase and proteases were used to liberate Spd from the bound form. In nuclei it appears that 60% of the label is associated with nucleic acids and 40% with the protein fraction. In view of evidence from animals indicating Spd binding to specific proteins during organogenesis, they are investigating the nature of the Spd binding protein(s).

Calculation of day and night emittance values  

NASA Technical Reports Server (NTRS)

In July 1983, the Thermal Infrared Multispectral Scanner (TIMS) was flown over Death Valley, California on both a midday and predawn flight within a two-day period. The availability of calibrated digital data permitted the calculation of day and night surface temperature and surface spectral emittance. Image processing of the data included panorama correction and calibration to radiance using the on-board black bodies and the measured spectral response of each channel. Scene-dependent isolated-point noise due to bit drops, was located by its relatively discontinuous values and replaced by the average of the surrounding data values. A method was developed in order to separate the spectral and temperature information contained in the TIMS data. Night and day data sets were processed. The TIMS is unique in allowing collection of both spectral emittance and thermal information in digital format with the same airborne scanner. For the first time it was possible to produce day and night emittance images of the same area, coregistered. These data add to an understanding of the physical basis for the discrimination of difference in surface materials afforded by TIMS.

Protein marker expression was assessed by electrophoresis and quantitative immunoblotting, and intracellular free Ca2+ ([Ca2+]i) measurements were accomplished using indo-1, a Ca(2+)-sensitive fluorescent dye. Contraction of SMC grown on deformable silicone films was monitored optically. Before the onset of cell division (3 to 6 days in culture), SMC still contained significant although decreasing amounts of smooth muscle myosin (SM1 and SM2 isoforms) and they started to express nonmuscle-type myosin. The relative content of 150-kDa caldesmon decreased, whereas the expression of 77-kDa caldesmon increased during this period. In the confluent primary culture (11 days), SM1 was expressed, but 150-kDa caldesmon was hardly detectable. Histamine (10(-5) mol/L), serotonin (10(-6) mol/L), and thrombin (1.5 units/mL) contracted deendothelialized rings of rabbit aorta, but only histamine was able to elevate [Ca2+]i 2.5- to 3-fold and induce reversible contraction of primary nondividing cells. [Ca2+]i elevation in response to histamine was due both to Ca2+ mobilization from intracellular stores and Ca2+ flux across the plasma membrane. After the onset of proliferation, SMC regained the ability to elevate [Ca2+]i in response to serotonin and thrombin but lost the ability to contract. Thus, primary cultured quiescent rabbit aortic SMC (3 to 6 days in culture) retain the essential features of vascular SMC in situ (eg, smooth muscle specific contractile and regulatory proteins, vasoactive hormone sensitivity, and contractility).

The role of p21cip1 in adaptation of CHO cells to suspension and protein-free culture.  

PubMed

The up-regulation of cyclin-dependent kinase inhibitor p21 has been shown to enhance productivity of monoclonal antibodies and has been linked to various regulatory processes. To identify the potential role of p21 in adaptation to suspension and protein-free cultures, we studied the survival and growth of anchorage- and serum-dependent CHO cell lines that differed only in the period of p21-induced arrest. p21 overexpression led to rapid adaptation of cells to suspension and protein-free cultures. The period taken to achieve adaptation was correlated with the time the cells were arrested after transfer from the monolayer and serum-fed culture. Interestingly, cell aggregation associated with protein-free suspension culture was reduced in p21 culture in response to the loss of cellular adherence. The processes of adaptation to suspension and arrest did not decrease monoclonal antibody productivity. In contrast, following adaptation to protein-free growth media, an overall increase in specific productivity was observed. The ability of cells to survive in protein-free suspension cultures was due to the requirement of G1 cells to growth factors and to their relatively high resistance to the hydrodynamic forces. This improved process has the advantage of reducing the duration of critical path activity for developing CHO commercial cell lines from 72 to 36 days. PMID:17544163

In vitro mineralization by mesenchymal stem cells cultured on titanium scaffolds.  

PubMed

Titanium has been utilized in the field of orthopaedic and dental reconstructive surgery, but mineralization through osteogenic differentiation of osteogenic cells on titanium surfaces has not been fully investigated. Here we cultured rat mesenchymal stem cells (MSCs) on the surfaces of titanium dishes in osteogenic media containing calcein which is a calcium-binding fluorescence dye. On titanium dishes, MSCs showed high viability to adhere to the surfaces and excellent proliferation. At day 14 of culture, MSCs differentiated into osteoblasts to form mineralized matrices on titanium dishes as well as tissue culture polystyrene (TCPS) dishes which are widely recognized as optimal culture substrates. Calcein was incorporated into the bone minerals fabricated by MSCs cultured on both substrates to show green emission under fluorescence microscopy. The fluorescence intensity was quantified with an image analyser during culture periods. These results indicate that the surfaces of titanium showed a high adhesion/proliferation potential to MSCs and that the titanium effectively supported the osteogenic differentiation of MSCs comparable to TCPS dishes. Therefore, the titanium is an effective scaffold that is applicable in bone reconstruction surgery. PMID:17383975

Day-to-day repeatability of the Pulse Time Index of Norm  

PubMed Central

The pulse wave velocity (PWV) threshold for hypertensive target organ damage is presently set at 10 meters per second. New 24-hour monitors (eg, BPLab® and Vasotens®) provide several PWV measurements over a period of 24–72 hours. A new parameter, ie, the Pulse Time Index of Norm (PTIN), can be calculated from these data. The PTIN is defined as the percentage of a 24-hour period during which the PWV does not exceed 10 meters per second. The aim of the present study was to test the new PTIN for clinical feasibility using day-to-day repeatability analysis. Oscillometrically generated waveform files (n=85), which were previously used for research studies, were reanalyzed using the new 2013 version software of the Vasotens technology program, which enables calculation of PTIN. The intraclass correlation coefficient was 0.98 and Cronbach’s alpha was 0.97, indicating that the PTIN has excellent day-to-day repeatability and internal consistency. The present results show adequate repeatability, and PTIN assessment using the Vasotens technology appears to be feasible. PMID:24600253

Effect of growth factors and steroid hormones on heme oxygenase and cyclin D1 expression in primary astroglial cell cultures.  

PubMed

Astrocyte activity may be modulated by steroid hormones and GFs. This study investigates the interaction between glucocorticoids or estrogens and GFs on the expression of heme oxygenase-1 (HO-1) and cyclin D1 in astrocyte cultures at 14 days treated for 48 or 60 hr with dexamethasone (DEX) or 48 hr with 17?-estradiol (E2 ) alone or with GFs added only in the last 12 or 24 hr. Twelve- or twenty-four-hour epidermal growth factor (EGF) treatment significantly enhanced HO-1 expression in astrocyte cultures pretreated for 48 hr with DEX. A highly significant increase in HO-1 expression was obtained after the last-12-hr EGF treatment in 48-hr E2 -pretreated astrocyte cultures; this enhancement was particularly significant in 48-hr E2 -pretreated cultures as well as in the last-12-hr insulin-treated ones pretreated for 48 hr with E2. Sixty-hour DEX-alone pretreatment as well as the last-12-hr EGF treatment in 60-hr DEX-pretreated astrocyte cultures showed a significant increase of cyclin D1 expression. A significant decrease of cyclin D1 expression in the last-12-hr insulin-like growth factor-I (IGF-1)-treated cultures pretreated for 60 hr with DEX was observed. A highly significant enhancement in cyclin D1 expression in 14 days in vitro astrocyte cultures pretreated with E2 alone for 48 hr and treated in the last 12 hr with IGF-1 in 48-hr E2 -pretreated cultures was found. Finally, the data highlight an interactive dialogue between the growth factors and glucocorticoids or estrogens during the maturation of astroglial cells in culture that may control the HO-1 and cyclin D1 expression as well as proliferating astroglial cells during the cell cycle. © 2014 Wiley Periodicals, Inc.

The day-to-day occurrence of equatorial plasma bubbles measured from Vanimo, Papua New Guinea  

NASA Astrophysics Data System (ADS)

An analysis of the occurrence of Equatorial Plasma Bubbles (EPBs) detected using a ground-based Global Positioning System (GPS) receiver located at Vanimo in South-east Asia will be presented. The 3-year (2000-2002) dataset employed shows that the EPB occurrence maximizes (minimizes) during the equinoxes (solstices), in good agreement with previous findings. The low-latitude ionosonde station at Vanimo is used in conjunction with the GPS receiver in an analysis of the day-to-day EPB occurrence variability during the equinox period. A superposed epoch analysis of the ionosonde data reveals that the height, and the change in height, of the F layer is 1 standard deviation (1?) larger on the days for which EPBs were detected, compared to non-EPB days. These results are interpreted using the generalized Rayleigh-Taylor (R-T) plasma instability growth rate, for which stronger upward drift of the lower-altitude F-layer plasma promotes faster growth of EPBs after sunset. These results are then compared to the results of the Thermosphere Ionosphere Electrodynamic General Circulation Model (TIEGCM), which surprisingly show strong similarities to the observations, despite only using geomagnetic and solar activity inputs. The TIEGCM is also used to directly calculate the hourly flux-tube integrated R-T growth rate. A superposed epoch analysis reveals that the modeled R-T growth rate is a little less than 1? higher on average for EPB days compared to non-EPB days. The implication of this result is that the TIEGCM generates almost enough day-to-day variability in order to account for the day-to-day EPB occurrence observed during the equinox. This result isn't necessarily expected due to the model's limited altitude coverage of 100-700 km (depending on solar activity) and the lack of ionospheric observation inputs. It is thought that the remaining variability could originate from either lower altitudes (e.g. atmospheric gravity waves from the troposphere) or from higher altitudes (resulting from coupling with the magnetosphere and solar wind), or potentially both. It is concluded that the continuing advancement of numerical modeling of the thermosphere and ionosphere, coupled with altitudes above and below, is required to better understand the day-to-day EPB occurrence.

Biomass production and nutrient removal potential of water hyacinth cultured in sewage effluent  

SciTech Connect

Growth and nutrient uptake of water hyacinth (Eichhornia crassipes (Mart) Solms) cultured in sewage effluent were measured over a period of 1 year in a prototype wastewater treatment system which has been in operation at Walt Disney World near Orlando, Florida. Annual productivity of water hyacinth cultured in primary sewage effluent (Channel II) was found to be in the range of 5 to 27 g dry wt m/sup -2/ day/sup -1/ (23.6 dry tons acre/sup -1/ yr/sup -1/). Average growth rate during the months of May through October 1982 for hyacinth cultured in Channel II (primary sewage effluent) and Channel I (treated primary sewage effluent leaving Channel II) was about 16 g dry wt m/sup -2/ day/sup -1/ (27 dry tons acre/sup -1/ yr/sup -1/), compared to the growth rate of 13 g dry wt m/sup -2/ day/sup -1/ (22 dry tons acre/sup -1/ yr/sup -1/) for hyacinths cultured in secondary sewage effluent. Plants cultured in secondary sewage effluent generally had longer roots than the plants cultured in primary sewage effluent. A significant relationship was observed between the growth rate of hyacinth and the solar radiation. Nitrogen and P concentration of the plant tissue were higher in the hyacinths cultured during winter months compared to the plants grown in summer months. Average N and P concentration of the plants cultured in primary sewage effluent were found to be 3.7 percent N and 0.94 percent P, respectively, while the plants cultured in secondary sewage effluent had a total N and P content of 2.8 percent N and 0.79 percent P. Nutrient ratios of the major plant nutrients were found to be approximately the same as the nutrient ratios in the sewage effluent. Annual N and P uptake rates of hyacinth cultured in sewage effluent were found to be in the range of 1176 to 1193 kg N ha/sup -1/ yr/sup -1/ and 321 to 387 kg P ha/sup -1/ yr/sup -1/, respectively.

Period Error Estimation for the Kepler Eclipsing Binary Catalog  

NASA Astrophysics Data System (ADS)

The Kepler Eclipsing Binary Catalog (KEBC) describes 2165 eclipsing binaries identified in the 115 deg2 Kepler Field based on observations from Kepler quarters Q0, Q1, and Q2. The periods in the KEBC are given in units of days out to six decimal places but no period errors are provided. We present the PEC (Period Error Calculator) algorithm, which can be used to estimate the period errors of strictly periodic variables observed by the Kepler Mission. The PEC algorithm is based on propagation of error theory and assumes that observation of every light curve peak/minimum in a long time-series observation can be unambiguously identified. The PEC algorithm can be efficiently programmed using just a few lines of C computer language code. The PEC algorithm was used to develop a simple model that provides period error estimates for eclipsing binaries in the KEBC with periods less than 62.5 days: log ? P ? - 5.8908 + 1.4425(1 + log P), where P is the period of an eclipsing binary in the KEBC in units of days. KEBC systems with periods >=62.5 days have KEBC period errors of ~0.0144 days. Periods and period errors of seven eclipsing binary systems in the KEBC were measured using the NASA Exoplanet Archive Periodogram Service and compared to period errors estimated using the PEC algorithm.

2011 Astronomy Day at McDonald Observatory  

NASA Astrophysics Data System (ADS)

Our philosophy is that everyday is Astronomy Day because the McDonald Observatory's Frank N. Bash Visitors Center is open 362 days a year. So, how did we create a special celebration for the "Astronomy Day” declared by the Astronomical League? During September 26-29 we conducted 20 videoconferences and served 12,559 students with "Astronomy Day” programming. Connect2Texas provides bridging for a network of Texas-based museums and cultural, historical, and scientific organizations that offer educational content to schools throughout the state via videoconferencing. Connect2Texas connected McDonald Observatory to 334 schools; most of these schools were in Texas, but schools in a dozen other states also participated. While most schools had a "view-only" connection, at least 20 of the schools had interactive connections, whereby the students could ask questions of the presenter. Connect2Texas also collects evaluation information from the participating schools that we will use to produce a report for our funders and make modifications to future programs as need be. The videoconferences were offered free of charge. The theme for the 2011 Astronomy Day program was the Year of the Solar System, which aligns with NASA's theme for 2011 and 2012. By aligning with this NASA theme, we could leverage NASA artwork and materials to both advertise and enrich the learning experience. Videoconference materials also included pre- and post-videoconference assessment sheets, an inquiry based activity, and pre- and post-videoconference activities, all of which were made available online. One of the lessons learned from past Astronomy Day videoconferences is that the days the Astronomical League declares as "Astronomy Day” are not always good days for Texas schools to participate. So, we choose an Astronomy Day that meets the needs of Texas schools and our schedule - so any day can be Astronomy Day. 2011 Astronomy Day was made possible by The Meyer-Levy Charitable Trust.

Culturability and toxicity of sick building syndrome-related fungi over time.  

PubMed

Two experiments were conducted regarding the culturability and toxicity of fungi located on building materials over time and the efficacy of seven laboratory techniques in recovering culturable fungi from sample swabs. In the first experiment, eight sections of drywall were inoculated with Stachybotrys chartarum and stored at 25 +/- 5 degrees Celsius and 20-60% relative humidity (RH) for up to two years. Another eight sections of ceiling tile were stored at 100% RH for 1 year. Six sections of ceiling tile and 15 swabs were also inoculated with Penicillium chrysogenum and S. chartarum respectively and stored under the same conditions for 8 months and 3.3 years. All materials were tested for culturability at the end of the storage period. S. chartarum-inoculated samples were also tested for toxicity. In the second experiment (replicated twice), S. chartarum and Chaetomium globosum were inoculated onto 84 swabs each. Storage was up to 266 days at 25 +/- 5 degrees Celsius and 20-60% RH. Seven techniques were compared regarding the recovery of culturable fungi from the swabs over different time points. Results for Experiment 1 showed that all samples were culturable after the storage period and that the S. chartarum-inoculated drywall samples were toxic. In Experiment 2, all techniques showed high rates of recovery. These data show that despite being without a water source, these organisms can be culturable and toxic after long periods of time under conditions similar to human-occupied dwellings and that a number of preparation techniques are suitable for the recovery of these fungi from inoculated swabs.

Mesenchymal stem cells cultured under hypoxia escape from senescence via down-regulation of p16 and extracellular signal regulated kinase  

SciTech Connect

Hypoxia has been considered to affect the properties of tissue stem cells including mesenchymal stem cells (MSCs). Effects of long periods of exposure to hypoxia on human MSCs, however, have not been clearly demonstrated. MSCs cultured under normoxic conditions (20% pO{sub 2}) ceased to proliferate after 15-25 population doublings, while MSCs cultured under hypoxic conditions (1% pO{sub 2}) retained the ability to proliferate with an additional 8-20 population doublings. Most of the MSCs cultured under normoxic conditions were in a senescent state after 100 days, while few senescent cells were found in the hypoxic culture, which was associated with a down-regulation of p16 gene expression. MSCs cultured for 100 days under hypoxic conditions were superior to those cultured under normoxic conditions in the ability to differentiate into the chondro- and adipogenic, but not osteogenic, lineage. Among the molecules related to mitogen-activated protein kinase (MAPK) signaling pathways, extracellular signal regulated kinase (ERK) was significantly down-regulated by hypoxia, which helped to inhibit the up-regulation of p16 gene expression. Therefore, the hypoxic culture retained MSCs in an undifferentiated and senescence-free state through the down-regulation of p16 and ERK.

Solar periodicity in energetic ions at Saturn  

NASA Astrophysics Data System (ADS)

Energetic protons (2.8-78 keV) and water group ions (8.8-78 keV) observed in Saturn's magnetosphere using the Magnetospheric Imaging Instrument/Charge-Energy-Mass Spectrometer instrument from 2005 through 2012 were subjected to a Lomb periodogram analysis with the period window extending from 0.5 to 50 days, and the data constrained to the spatial region between 10 RS (1 RS = 60,268 km) and the magnetopause. Both the protons and water group ions exhibited solar periodicity at ~26 days and harmonics thereof. For all ions, the 26 day periodicities were strong on the dayside and duskside, weak at dusk, and virtually nonexistent on the nightside. The solar periodicity was evident during both the first and second halves of the 7 year time span, but strongest in the first half from January 2004 to July 2008. Some of the ion spectral peaks, especially for the water group ions, can be associated with orbital motion of the spacecraft. The 26 day periodicities are likely caused by corotating interaction regions in the solar wind that periodically sweep past Saturn, regularly compressing its dayside magnetosphere, but not its nightside.

Persistent infections of a field strain of rabies virus in murine neuroblastoma (NA-C1300) cell cultures.  

PubMed Central

Rabies virus from the brain of a striped skunk (Mephitis mephitis) from Ontario was inoculated into murine neuroblastoma (NA-C1300) cell cultures. These cultures were incubated and the cells were subcultured every three to four days. The presence of viral antigen in the cell cultures was monitored by direct immunofluorescent staining and in the culture fluids by titration in either baby hamster kidney (BHK/C13) or NA cells or in experimental mice. The virus-infected NA cultures evolved from an initial high viral concentration in supernatant fluid through a period of decreasing titers of infectious virus in the supernatant fluids to a final phase where no infectious virus has been found following cell culture and animal inoculation methods attempted although the persistently infected cells remained 95-100% viral nucleocapsid antigen-positive. Possible mechanisms involved in the perpetuation of this infection are discussed. This is the first report of a persistent infection of cell cultures by a field strain of rabies virus. PMID:2590871

Cadmium was added to the cultures in amounts of 100 to 0.13 µg l-1. In one series it was added at the start of the experiments and in a second one after a growth period of 1 week. Addition of only 1.2 µg Cd l-1 reduces multiplication rates and maximum cell densities of the algae. Not until 0.4 µg Cd-1 does growth correspond to that of the controls. Cadmium concentrations were measured, after filtration, in the culture medium and in the biomass by means of flameless AAS. The cadmium content in algae increased from 2.7 µg g-1 (dry weight) in controls to 500 µg g-1 (dry weight) in media containing 100 µg Cd l-1. Uptake occurred rapidly during the first few days of the experiments, slowed down somewhat during exponential growth stage, and increased during decay of the cultures. Cadmium content of culture media remained nearly constant (Series 1) or decreased only slowly during experimental time (Series 2). The highest concentration factor was measured in the controls. It decreased with increasing metal concentration in the medium and increased with experimental time. Structural modifications of the cells were visible after Lugol fixation only, indicating brittleness of the cell walls. P. micans has shown to be extremely sensitive to cadmium and to accumulate this metal.

Plant Cultures  

NSDL National Science Digital Library

With its radiant colors and well-thought-out design, the Plant Cultures website's primary goal is "to convey the richness and complexity of links between Britain and South Asia, through the story of plants and people". The project covers both the historical and contemporary aspects of Britain and South Asia through a wide range of resources, including historic images, recipes, and other items. Through a series of tabs at the top of the homepage (such as "Themes" and "Stories"), visitors can begin to explore the diverse content offered here. The "Plants" area is a good place to start, as visitors can learn about garlic, henna, holy basil, sugar cane, and 21 other plants. One rather fun area of the site is the Story Library, where visitors can place their own stories regarding the use of different plants, and read those from previous guests.

Abiotic elicitation of gymnemic acid in the suspension cultures of Gymnema sylvestre.  

PubMed

Elicitation is one of the few strategies that find commercial application in the enhancement of secondary metabolite production from plants as well as cell culture systems. Due to their immense medicinal value, production of saponins in suspension cultures has been attempted by many researchers. Gymnema sylvestre is a rich source of gymnemic acids (saponins) that find application in the treatment of diabetes. The present study is an attempt to evaluate the effect of various metal salts (cadmium chloride, mercuric chloride, silver nitrate, cupric chloride, cobaltous chloride and calcium chloride) in eliciting the response from G. sylvestre suspension cultures. The maximum gymnemic acid production in the suspensions was achieved on day 12 of culture, though the maximum biomass was obtained on day 16. Among the different salts, CdCl(2) gave maximum response (59.97 mg/gDCW) at 2 mM concentration after a 24 h time period, while, AgNO(3) gave the least response (18.35 mg/gDCW) on incubation of 48 h at 1 mM concentration, in terms of gymnemic acid accumulation. The accumulation of gymnemic acid was found to be dependent on treatment time and concentration of the elicitor. The enhanced gymnemic acid production shown by the suspensions in response to the metal salts indicates their role in evoking the plant defense mechanisms. These elicitation studies help in providing a platform for improved commercial supply of bioactive gymnemic acids. PMID:22806870

Endothelial injury and healing in vitro. Studies using an organ culture system.  

PubMed Central

The authors have developed an organ culture system in which segments of rabbit aorta were used for the study of the healing of superficial, intimal injury analogous to that produced in vivo by a nylon monofilament catheter. Aortic segments containing an intact endothelial monolayer were obtained for culture by careful avoidance of the damaging consequences of loss of vascular pressure, vasocontraction, and thrombosis. The segment could be maintained in culture for several weeks. Repair of superficial injury was studied after placing a series of precisely located injuries, 100 mu wide, on each aortic segment over a period of several days. The pattern of healing observed was similar to that observed in vivo. The wounded area was recovered by migrating cells within 24 hours, and during succeeding days these cells underwent a predictable pattern of remodeling which restored the normal morphologic features of the endothelium. The cells within the wound underwent a burst of cell division between 24 and 96 hours after injury and subsequently became quiescent. This organ culture approach potentially allows the investigation of many consequences of endothelial injury in a system which provides far greater control and manipulation of the cellular environment than is possible in vivo.

A Genetically Modified Protein-Based Hydrogel for 3D Culture of AD293 Cells  

PubMed Central

Hydrogels have strong application prospects for drug delivery, tissue engineering and cell therapy because of their excellent biocompatibility and abundant availability as scaffolds for drugs and cells. In this study, we created hybrid hydrogels based on a genetically modified tax interactive protein-1 (TIP1) by introducing two or four cysteine residues in the primary structure of TIP1. The introduced cysteine residues were crosslinked with a four-armed poly (ethylene glycol) having their arm ends capped with maleimide residues (4-armed-PEG-Mal) to form hydrogels. In one form of the genetically modification, we incorporated a peptide sequence ‘GRGDSP’ to introduce bioactivity to the protein, and the resultant hydrogel could provide an excellent environment for a three dimensional cell culture of AD293 cells. The AD293 cells continued to divide and displayed a polyhedron or spindle-shape during the 3-day culture period. Besides, AD293 cells could be easily separated from the cell-gel constructs for future large-scale culture after being cultured for 3 days and treating hydrogel with trypsinase. This work significantly expands the toolbox of recombinant proteins for hydrogel formation, and we believe that our hydrogel will be of considerable interest to those working in cell therapy and controlled drug delivery.

Optimization of elicitation conditions with methyl jasmonate and salicylic acid to improve the productivity of withanolides in the adventitious root culture of Withania somnifera (L.) Dunal.  

PubMed

Adventitious root cultures derived from leaf derived callus of Withania somnifera (L.) Dunal were treated with methyl jasmonate and salicylic acid independently. Biomass accumulation, culture age, elicitation period, and culture duration were optimized for higher withanolides production in the two best-responding varieties collected from Kolli hills (Eastern Ghats) and Cumbum (Western Ghats) of Tamil Nadu, India. Between the two elicitors, salicylic acid (SA) improved the production of major withanolides (withanolide A, withanolide B, withaferin A, and withanone) as well as minor constituents (12-deoxy withastramonolide, withanoside V, and withanoside IV) in the Kolli hills variety. Treatment of root biomass (11.70 g FW) on 30-day-old adventitious root cultures with 150 ?M SA for 4 h elicitor exposure period resulted in the production of 64.65 mg g(-l) dry weight (DW) withanolide A (48-fold), 33.74 mg g(-l) DW withanolide B (29-fold), 17.47 mg g(-l) DW withaferin A (20-fold), 42.88 mg g(-l) DW withanone (37-fold), 5.34 mg g(-l) DW 12-deoxy withastramonolide (nine fold), 7.23 mg g(-l) DW withanoside V (seven fold), and 9.45 mg g(-l) DW withanoside IV (nine fold) after 10 days of elicitation (40th day of culture) when compared to untreated cultures. This is the first report on the use of elicitation strategy on the significant improvement in withanolides production in the adventitious root cultures of W. somnifera. PMID:22843063

Women in Guam consume more calories during feast days than during non-feast days  

PubMed Central

Parties (feast days) have become increasingly frequent and abundant, in terms of food, on the island of Guam. Considering the potential impact of this frequency and abundance on food intake, this study compared food intake during feast days and non-feast days of women in Guam (25 Chamorros; 24 Filipinas). The women (?40 yr) recalled foods they usually consumed during feast days. Subsequently, a 24-hour dietary recall for a non-feast day was completed by a subsample (n=25). Height, weight, and waist circumference were measured to assess obesity status. Statistical analyses (paired t-test, ANOVA, and chi-square test) were performed with SPSS. Compared to a non-feast day, the women reported higher intakes of dietary energy (2645.0 ± 1125.8 versus 1654.0 ± 718.8 kcal/day), carbohydrates (43.8 ± 11.5% versus 51.8 ± 10.2% of kcal), total fat (34.1 ± 7.8% versus 27.5 ± 9.6% of kcal), saturated fat (11.4 ± 4.7% versus 7.9 ± 3.4% of kcal), and sugar (89.5 ± 62.8 versus 47.3 ± 42.2 g/day) on feast days. Chamorros, compared to Filipinas, reported higher dietary energy density (1.7 ± 0.4 versus 1.4 ± 0.3 kcal/g), total fat (35.3 ± 8.9% versus 30.7 ± 6.8% of kcal), and saturated fat (12.4 ± 4.9% versus 9.4 ± 3.3% of kcal); and lower servings of fruit (0.5 ± 1.0 versus 2.7 ± 1.8) on feast days. Fourteen Chamorros (56.0%) and one Filipina (4.1%) were classified as obese. Current feasting behaviors of women in Guam may contribute to obesity if continued for a long period. The women would benefit by choosing more fruit and vegetable dishes in place of high-energy dishes. Chamorro women would particularly benefit by reducing saturated fat intake. Traditional foods, such as taro, breadfruit, seafood, fruits, and vegetables, would help accomplish this and thus should be promoted at parties on Guam.

The Pace of Cultural Evolution  

PubMed Central

Today, humans inhabit most of the world’s terrestrial habitats. This observation has been explained by the fact that we possess a secondary inheritance mechanism, culture, in addition to a genetic system. Because it is assumed that cultural evolution occurs faster than biological evolution, humans can adapt to new ecosystems more rapidly than other animals. This assumption, however, has never been tested empirically. Here, I compare rates of change in human technologies to rates of change in animal morphologies. I find that rates of cultural evolution are inversely correlated with the time interval over which they are measured, which is similar to what is known for biological rates. This correlation explains why the pace of cultural evolution appears faster when measured over recent time periods, where time intervals are often shorter. Controlling for the correlation between rates and time intervals, I show that (1) cultural evolution is faster than biological evolution; (2) this effect holds true even when the generation time of species is controlled for; and (3) culture allows us to evolve over short time scales, which are normally accessible only to short-lived species, while at the same time allowing for us to enjoy the benefits of having a long life history.

Culturing the adolescent brain: what can neuroscience learn from anthropology?  

PubMed Central

Cultural neuroscience is set to flourish in the next few years. As the field develops, it is necessary to reflect on what is meant by ‘culture’ and how this can be translated for the laboratory context. This article uses the example of the adolescent brain to discuss three aspects of culture that may help us to shape and reframe questions, interpretations and applications in cultural neuroscience: cultural contingencies of categories, cultural differences in experience and cultural context of neuroscience research. The last few years have seen a sudden increase in the study of adolescence as a period of both structural and functional plasticity, with new brain-based explanations of teenage behaviour being taken up in education, policy and medicine. However, the concept of adolescence, as an object of behavioural science, took shape relatively recently, not much more than a hundred years ago and was shaped by a number of cultural and historical factors. Moreover, research in anthropology and cross-cultural psychology has shown that the experience of adolescence, as a period of the lifespan, is variable and contingent upon culture. The emerging field of cultural neuroscience has begun to tackle the question of cultural differences in social cognitive processing in adults. In this article, I explore what a cultural neuroscience can mean in the case of adolescence. I consider how to integrate perspectives from social neuroscience and anthropology to conceptualize, and to empirically study, adolescence as a culturally variable phenomenon, which, itself, has been culturally constructed.

Triple-layered mixed co-culture model of RPE cells with neuroretina for evaluating the neuroprotective effects of adipose-MSCs.  

PubMed

Mesenchymal stem cell (MSC) therapy is promising for neuroprotection but there is no report of an appropriate in vitro model mimicking the situation of the in vivo retina that is able to test the effect of MSCs in suspension or encapsulated with/without a drug combination. This study aims to establish a viable mixed co-culture model having three layers: neuroretina explants (NRs), retinal pigment epithelium (RPE) cells and adipose tissue-derived MSCs (AT-MSCs) for evaluating adipose-MSC effects. AT-MSCs were grown on the lower surface of a transwell membrane and RPE cells were grown on the bottom of a culture plate as monocultures. A transwell membrane was inserted into a culture plate well. NR was placed as an organotypic culture on the upper surface of the transwell membrane. Thus, a triple-layered co-culture setup was constructed. In double-layered setups, NR were co-cultured with AT-MSCs or RPE cells. Optimum medium, experiment execution period and transwell membrane permeability (TMP) were determined. MSC effects on RPE cell proliferation and NR reactive gliosis were evaluated. Limitations were discussed. Our study shows that neurobasal A with DMEM (1:1) mixed medium was suitable for viability of all three layers. AT-MSC growth decreased TMP significantly, 30-60 % in 3- to 6-day periods. Spontaneous NR reactive gliosis limits the experiment execution period to 6 days. AT-MSCs maintained their undifferentiated nature and showed no or limited neuroprotective effects. In this study, we successfully assembled viable double- and triple-layered co-culture setups for AT-MSCs, RPE and NR, optimised conditions for their survival and explored setup Limitations.

Mathematical Aspects of the Periodic Law

We review different studies of the Periodic Law and the set of chemical elements from a mathematical point of view. This discussion covers the first attempts made in the 19th century up to the present day. Mathematics employed to study the periodic system includes number theory, information theory, order theory, set theory and topology. Each theory used shows that it is possible to provide the Periodic Law with a mathematical structure. We also show that it is possible to study the chemical elements taking advantage of their phenomenological properties, and that it is not always necessary to reduce the concept of chemical elements to the quantum atomic concept to be able to find interpretations for the Periodic Law. Finally, a connection is noted between the lengths of the periods of the Periodic Law and the philosophical Pythagorean doctrine.

Short-Term Periodicity in Solar Mean Magnetic Field during Activity Maximum and Minimum Periods  

NASA Astrophysics Data System (ADS)

The short-term periodicity in the solar mean magnetic field (SMMF) observed at the Wilcox Solar Observatory during the last four activity cycles is investigated by using Lomb-Scargle periodograms. Our results show that the SMMF has main periods of about 27, 13.5, and 9 days in both the maximum and minimum years of each activity cycle. The SMMF has the most dominant period of about 27 days during the activity maxima. However, during the activity minimum years the 13.5-day periodicity is the most significant, except for the minimum of 1984 - 1986. These results indicate that the distribution of active regions in the activity maximum years is quite different from that in the minimum years.

Routine Testing for Anaerobic Bacteria in Cerebrospinal Fluid Cultures Improves Recovery of Clinically Significant Pathogens  

PubMed Central

In North America, the widespread use of vaccines targeting Haemophilus influenzae type b and Streptococcus pneumoniae have dramatically altered the epidemiology of bacterial meningitis, while the methodology for culturing cerebrospinal fluid (CSF) specimens has remained largely unchanged. The aims of this study were 2-fold: to document the current epidemiology of bacterial meningitis at a tertiary care medical center and to assess the clinical utility of routinely querying for anaerobes in CSF cultures. To that end, we assessed CSF cultures submitted over a 2-year period. A brucella blood agar (BBA) plate, incubated anaerobically for 5 days, was included in the culture procedure for all CSF specimens during the second year of evaluation. In the pre- and postimplementation years, 2,353 and 2,302 CSF specimens were cultured, with 49 and 99 patients having positive culture results, respectively. The clinical and laboratory data for patients with positive cultures were reviewed. Anaerobic bacteria were isolated in the CSF samples from 33 patients post-BBA compared to two patients pre-BBA (P = 0.01). The anaerobic isolates included Bacteroides thetaiotaomicron (n = 1), Propionibacterium species (n = 15), and Propionibacterium acnes (n = 19) isolates; all of these isolates were recovered on the BBA. Eight of the 35 patients from whom anaerobic organisms were isolated received antimicrobial therapy. Although six of these patients had central nervous system hardware, two patients did not have a history of a neurosurgical procedure and had community-acquired anaerobic bacterial meningitis. This study demonstrates that the simple addition of an anaerobically incubated BBA to the culture of CSF specimens enhances the recovery of clinically significant anaerobic pathogens. PMID:24622102

IRI is doing an excellent job in accurately representing these average conditions as countless comparisons with additional data have shown and as acknowledged by the fact that international organizations (COSPAR, URSI, ISO, ECSS) have accepted IRI as their ionosphere standard. However, with our ever-increasing dependence on space technology it has become important to go beyond the monthly averages and to provide a description of the day-to-day variability of the ionosphere. We will review past and ongoing efforts to provide IRI users with a quantitative description of ionospheric variability depending on altitude, time of day, time of year, latitude and solar and magnetic activity. We will present new results from an analysis of ISIS and Alouette topside sounder data. The IRI team is also pursuing the development of an IRI Real-Time (IRI-RT) that uses assimilative algorithms or updating procedures to combine IRI with real-time data for a more accurate picture of current ionospheric conditions. We will review the status of these activities and report on latest results.

Comparison of neuroplastin and synaptic marker protein expression in acute and cultured organotypic hippocampal slices from rat.  

PubMed

Organotypic hippocampal slice cultures can be used to study hippocampal biochemistry and physiology over a chronic period on the days to weeks timescale. In order to validate the organotypic hippocampal slice culture for our ongoing studies of synaptic function, we have compared, using Western blotting, the levels of a number of synaptic proteins from in vitro organotypic hippocampal slice cultures with those from in vivo hippocampal slices prepared from age-matched controls. We chose to follow the developmental expression of the neuroplastin (np) family of immunoglobulin related cell adhesion molecules (CAMs), np65, a brain specific isoform highly expressed in hippocampal neurones and np55 a more widely expressed isoform and two synaptic marker proteins, synaptophysin, a pre-synaptic marker and post-synaptic density protein-95, PSD95, a post-synaptic marker. All showed increasing expression over the developmental time period, both in vivo and in vitro. The level of both neuroplastins was also consistent between the in vivo and in vitro preparations, whereas the level of PSD95 was markedly increased in the organotypic hippocampal slice cultures while the level of synaptophysin was slightly decreased. Whilst these findings may indicate some differences in the composition and organisation of synapses, the developmental expression profiles of these synaptic proteins within organotypic hippocampal slice cultures suggests they are a valid model for the study of synapse function and development in vitro.

Seven-day clotrimazole therapy for vulvovaginal candidiasis.  

PubMed

There were 150 patients with mycologically proven vulvovaginal candidiasis in a randomized, non-cross-over study which compared seven-and 14-day treatment courses of clotrimazole vaginal tablets (Gyne-Lotrimin) with a 14-day treatment course of miconazole nitrate 2% vaginal cream (Monistat). Adequate data for analyses were obtained for 117 patients. When patients were reexamined four or more weeks after completion of therapy, success rates, based on clinical and mycologic criteria, were: 88% for patients treated with clotrimazole for seven days, 84% for clotrimazole 14-day treatment, and 78% for miconazole nitrate 14-day treatment. There were no drug-related adverse reactions. Thus a seven-day course of therapy with clotrimazole is effective as is a 14-day course of either clotrimazole or miconazole nitrate 2% for the treatment of Candida vaginitis. Statistical analysis revealed no significant differences among the clotrimazole seven-and 14-day treatment groups and the miconazole nitrate 14-day treatment group. The shorter period of administration required for this new antifungal agent should result in better patient compliance and an improved success rate in the rate in the treatment of this frequently encountered infection.

Effects of Polysaccharide Elicitors on Secondary Metabolite Production and Antioxidant Response in Hypericum perforatum L. Shoot Cultures  

PubMed Central

The effects of polysaccharide elicitors such as chitin, pectin, and dextran on the production of phenylpropanoids (phenolics and flavonoids) and naphtodianthrones (hypericin and pseudohypericin) in Hypericum perforatum shoot cultures were studied. Nonenzymatic antioxidant properties (NEAOP) and peroxidase (POD) activity were also observed in shoot extracts. The activities of phenylalanine ammonia lyase (PAL) and chalcone-flavanone isomerase (CHFI) were monitored to estimate channeling in phenylpropanoid/flavonoid pathways of elicited shoot cultures. A significant suppression of the production of total phenolics and flavonoids was observed in elicited shoots from day 14 to day 21 of postelicitation. This inhibition of phenylpropanoid production was probably due to the decrease in CHFI activity in elicited shoots. Pectin and dextran promoted accumulation of naphtodianthrones, particularly pseudohypericin, within 21 days of postelicitation. The enhanced accumulation of naphtodianthrones was positively correlated with an increase of PAL activity in elicited shoots. All tested elicitors induced NEAOP at day 7, while chitin and pectin showed increase in POD activity within the entire period of postelicitation. The POD activity was in significantly positive correlation with flavonoid and hypericin contents, suggesting a strong perturbation of the cell redox system and activation of defense responses in polysaccharide-elicited H. perforatum shoot cultures.

Construction of Mesenchymal Stem Cell–Containing Collagen Gel with a Macrochanneled Polycaprolactone Scaffold and the Flow Perfusion Culturing for Bone Tissue Engineering  

PubMed Central

Abstract A novel bone tissue-engineering construct was developed by using poly(?-caprolactone) (PCL)-macrochanneled scaffolds combined with stem cell-seeded collagen hydrogels and then applying flow perfusion culture. Rat mesenchymal stem cells (MSCs) were loaded into collagen hydrogels, which were then combined with macrochanneled PCL scaffolds. Collagen hydrogels were demonstrated to provide favorable growth environments for MSCs and to foster proliferation. Cell number determination identified retention of substantially fewer (50–60%) cells when they were seeded directly onto macrochanneled PCL than of cells engineered within collagen hydrogels. Additionally, the cells actively proliferated within the combined scaffold for up to 7 days. MSC-loaded collagen–PCL scaffolds were subsequently cultured under flow perfusion to promote proliferation and osteogenic differentiation. Cells proliferated to levels significantly higher in flow perfusion culture than that under static conditions during 21 days. A quantitative polymerase chain reaction (QPCR) assay revealed significant alterations in the transcription of bone-related genes such as osteopontin (OPN), osteocalcin (OCN), and bone sialoprotein (BSP), such as 8-, 2.5-, and 3-fold induction, respectively, after 10 days of flow perfusion relative to those in static culture. OPN and OCN protein levels, as determined by Western blot, increased under flow perfusion. Cellular mineralization was significantly enhanced by the flow perfusion during 21 and 28 days. Analyses of mechanosensitive gene expression induced by flow perfusion shear stress revealed significant upregulation of c-fos and cyclooxygenase-2 (COX-2) during the initial culture period (3–5 days), suggesting that osteogenic stimulation was possible as a result of mechanical force-driven transduction. These results provide valuable information for the design of a new bone tissue-engineering system by combining stem cell-loaded collagen hydrogels with macrochanneled scaffolds in flow perfusion culture.

A system for automated, noninvasive, morphology-based evaluation of induced pluripotent stem cell cultures.  

PubMed

Due to the rapid adoption and use of human induced pluripotent stem cells (iPSCs) in recent years, there is a need for new technologies that standardize the evaluation of iPSCs to allow the objective comparison of results across different experiments and groups. In this article, we present a noninvasive, fully automated, and analytical system for morphology-based evaluation of iPSC cultures that consists of time-lapse microscopy and novel image analysis software. The presented system acquires low-light phase-contrast images of iPSC growth collected during a period of several days in culture, measures geometrical- and texture-based features of iPSC colonies throughout time, and derives a set of six biologically relevant features to automatically rank the quality of the cell culture. In a study of 94 iPSC cultures, we demonstrated the accuracy of the system by comparing the automated ranking with an independent expert evaluation based on visual review of the time-lapse movies. To our knowledge, this is the first demonstration of a fully automated and objective assessment of iPSC culture quality using noninvasive methods. PMID:24888327

Simulating tumor microenvironment: changes in protein expression in an in vitro co-culture system  

PubMed Central

Background The role of the microenvironment during the initiation and progression of carcinogenesis is thought to be of critical importance, both for the enhanced understanding of fundamental cancer biology as well as for improving molecular diagnostics and therapeutics. The aim of this study was to establish an in vitro model based on a co-culture of healthy human fibroblasts (HFs) and human osteosarcoma cells (MG-63s) to simulate the microenvironment including tumor and healthy cells. Methods The HFs and MG-63s were in vitro co-cultured for a period of time ranging from 24 h to 7 days. Cell morphology and organization were studied using phase contrast microscopy while the expression of Human Cartilage Glycoprotein 39 (YKL-40), Vascular Endothelial Growth Factor (VEGF) and Matrix Metalloprotease 1 (MMP1) was investigated by Real Time PCR and Western Blotting. Results The results showed a characteristic disposition of tumor and healthy co-cultured cells in columns which are not visible in tumor and healthy cells grown singularly. The expression of YKL-40, VEGF and MMP1 significantly changed in co-cultured cells compared to HFs and MG-63s separately cultured. Conclusions We concluded that the tumor microenvironment has an influence on the protein expression of the healthy surrounding tissues and the process of tumorigenicity. PMID:24883044

Cryotolerance of Day 2 or Day 6 in vitro produced ovine embryos after vitrification by Cryotop or Spatula methods.  

PubMed

This study was conducted to evaluate the cryotolerance of in vitro produced ovine embryos submitted to vitrification at different developmental stages using two methods of minimum volume and rapid cooling rate. Embryos were vitrified at early stage (2 to 8-cells) on Day 2 or at advanced stage (morulae and blastocysts) on Day 6 after in vitro fertilization. Vitrification procedure consisted of the Cryotop (Day 2, n=165; Day 6, n=174) or the Spatula method (Day 2, n=165; Day 6, n=175). Non vitrified embryos were maintained in in vitro culture as a control group (n=408). Embryo survival was determined at 3h and 24h after warming, development and hatching rates were evaluated on Day 6 and Day 8 after fertilization, and total cell number was determined on expanded blastocysts. Embryo survival at 24h after warming increased as the developmental stage progressed (P<0.05) and was not affected by the vitrification method. The ability for hatching of survived embryos was not affected by the stage of the embryos at vitrification or by the vitrification method. Thus, the proportion of hatching from vitrified embryos was determined by the survival rate and was lower for Day 2 than Day 6 vitrified embryos. The percentage of blastocysts on Day 8 was lower for the embryos vitrified on Day 2 than Day 6 (P<0.05), and was lower for both days of vitrification than for non-vitrified embryos (P<0.05). No interaction of embryo stage by vitrification method was found (P=NS) and no significant difference was found in the blastocyst cell number among vitrified and non-vitrified embryos. In conclusion, both methods using minimum volume and ultra-rapid cooling rate allow acceptable survival and development rates in Day 2 and Day 6 in vitro produced embryos in sheep. Even though early stage embryos showed lower cryotolerance, those embryos that survive the vitrification-warming process show high development and hatching rates, similar to vitrification of morulae or blastocysts.

Five-Day Cefdinir Treatment for Streptococcal Pharyngitis  

PubMed Central

A multicenter, randomized, controlled, investigator-blind study was performed to evaluate the safety and efficacy of oral cefdinir versus oral penicillin V for the treatment of pharyngitis due to group A beta-hemolytic streptococci (GABHS). Patients 13 years of age and older were randomized to receive either oral cefdinir (300 mg twice a day) for 5 days followed by placebo for 5 days or oral penicillin V (250 mg four times a day) for 10 days. Throat cultures were obtained, and signs and symptoms of pharyngitis were recorded at study admission and follow-up visits on study days 11 to 15, 16 to 20, and 25 to 31. Patients kept a diary to record medication intake and their assessment of throat pain at admission and at each day of study treatment. Five hundred fifty-eight patients were enrolled, of whom 432 (77.4%) were clinically and microbiologically evaluable. The GABHS eradication rates 5 to 10 days after completion of therapy were 193 of 218 (88.5%) in the cefdinir group and 176 of 214 (82.2%) in the penicillin group (P = 0.053). Clinical cure rates were 89.0 and 84.6%, respectively (P = 0.80). By the time of the long-term follow-up visit, 2 to 3 weeks after completion of treatment, 156 of 191 (81.7%) of the assessable cefdinir patients and 152 of 195 (77.9%) of the penicillin patients remained free of GABHS. Both treatments were well tolerated, with adverse reaction rates of 18.3% in the cefdinir study arm and 15.0% in the penicillin study arm (P = 0.278). Five-day treatment with cefdinir is safe and effective therapy for GABHS pharyngitis. Based on its twice-a-day dosage and shorter course of therapy, leading to potentially greater patient compliance, cefdinir may be considered for use in the treatment of pharyngitis caused by GABHS.

Walz having completed five days of joint operations between the American astronauts and the Russian cosmonauts are seen flying solo once again after undocking from the Mir Space Station. As Atlantis/Mir flew over the Ural Mountains of central Asia, the docking hooks and latches that joined the vehicles together were commanded open and Atlantis drifted slowly away from Mir. Wilcutt then initiated a tail-forward fly-around of the Russian space station. After one and one-half revolutions around Mir, Atlantis' jets were fired in a separation maneuver to enable Atlantis to break away from Mir. On board Atlantis, the six-member crew is settling back into its normal routine with a fairly light schedule for the remainder of the day. Early in the morning as Atlantis flew over the United States, the crew took time to talk with anchors for the CBS Up to the Minute' network news broadcast.
