Characterization of non-LTR retrotransposable TRAS elements in the aphids Acyrthosiphon pisum and Myzus persicae (Aphididae, Hemiptera).  

PubMed

A non-LTR TRAS retrotransposon (identified as TRASAp1) has been amplified in the pea aphid Acyrthosiphon pisum and its presence has been assessed also in the peach potato aphid Myzus persicae. This TRAS element possesses 2 overlapping ORFs (a gag-ORF1 and a pol-ORF2 containing the reverse transcriptase and the endonuclease domains) that show a similarity ranging from 40% to 48% to proteins coded by other TRAS elements identified in insects (including the beetle Tribolium castaneum and the moth Bombyx mori). The study of the TRAS chromosomal insertion sites, performed by standard fluorescent in situ hybridization (FISH) and fiber FISH, showed that TRAS elements were located in a subtelomeric position, just before the telomeric (TTAGG) n repeats. In both the aphid species, TRAS elements were present at all termini of autosomes, but the 2 X chromosome telomeres show a clear-cut structural difference. Indeed, cromomycin A3 staining, together with FISH using a TRAS probe, revealed that TRAS signals only occur at the telomere opposite to the NOR-bearing one. Lastly, the analysis of the distribution of TRAS retrotransposons in a M. persicae strain possessing spontaneous fragmentations of the X chromosomes assessed that TRAS elements were not involved in the healing of de novo telomeres.

Dear-Mama: A photon counting X-ray imaging project for medical applications  

NASA Astrophysics Data System (ADS)

Dear-Mama ( Detection of Early Markers in Mammography) is an EU funded project devoted to develop an X-ray Medical imaging device based on room temperature solid-state pixel detector coupled to photon counting readout electronics via bump bonding. The technology being used leads to signal-to-noise ratio enhancement and thus the ability to detect low contrast anomalies such as micro-calcifications. The Dear-Mama machine is currently being evaluated and preliminary results show an excellent MTF response. Dear-Mama consortium is made up from six European institutions, the project runs from December 2001 to March 2006.

Scientific Requirements for Thermal Control and Scheduling of the STIS MAMA detectors after SM-3  

NASA Astrophysics Data System (ADS)

The installation of the Aft Shroud Cooling System (ASCS) on the next HST servicing mission will increase the scientific productivity of STIS by reducing the dark current in the MAMA detectors. The "dark glow" now observed in the FUV-MAMA detector is expected to go away at the ~24 oC nominal operating temperature after SM3. For the NUV-MAMA, typical dark currents will range from 800 to 1100 cts/s. However, for periods of roughly 10 days at a time, the dark current can be reduced to 200-450 cts/s. This is accomplished by warming the NUV-MAMA to ~38 oC for about 15 days, then cooling rapidly to as low an operating temperature as possible (20 oC is assumed here). This ISR presents an analysis of the NUV-MAMA dark current behavior during the HDF-S campaign, where a similar "cooling campaign" was attempted. It then makes predictions for the NUV-MAMA performance after SM3 and presents recommendations for the number and duration of cooling campaigns. Finally, some preliminary technical requirements for such campaigns are set out.

Anticipated uncertainty budgets of PRARETIME and T2L2 techniques as applied to ExTRAS  

NASA Technical Reports Server (NTRS)

The Experiment on Timing Ranging and Atmospheric Soundings, ExTRAS, was conceived jointly by the European Space Agency, ESA, and the Russian Space Agency, RSA. It is also designated the 'Hydrogen-maser in Space/Meteor-3M project'. The launch of the satellite is scheduled for early 1997. The package, to be flown on board a Russian meteorological satellite includes ultra-stable frequency and time sources, namely two active and auto-tuned hydrogen masers. Communication between the on-board hydrogen masers and the ground station clocks is effected by means of a microwave link using the modified version for time transfer of the Precise Range And Range-rate Equipment, PRARETIME, technique, and an optical link which uses the Time Transfer by Laser Link, T2L2, method. Both the PRARETIME and T2L2 techniques operate in a two-directional mode, which makes it possible to carry out accurate transmissions without precise knowledge of the satellite and station positions. Due to the exceptional quality of the on-board clocks and to the high performance of the communication techniques with the satellite, satellite clock monitoring and ground clocks synchronization are anticipated to be performed with uncertainties below 0.5 ns (1 sigma). Uncertainty budgets and related comments are presented.

Satellite test of the isotropy of the one-way spe ed of light using ExTRAS  

NASA Technical Reports Server (NTRS)

A test of the second postulate of special relativity, the universality of the speed of light, using the ExTRAS (Experiment on Timing Ranging and Atmospheric Sounding) payload to be flown on board a Russian Meteor-3M satellite (launch date January 1997) is proposed. The propagation time of a light signal transmitted from one point to another without reflection would be measured directly by comparing the phases of two hydrogen maser clocks, one on board and one on the ground, using laser or microwave time transfer systems. An estimated uncertainty budget of the proposed measurements is given, resulting in an expected sensitivity of the experiment of delta c/c is less than 8xl0(exp -10) which would be an improvement by a factor of approximately 430 over previous direct measurements and by a factor of approximately 4 over the best indirect measurement. The proposed test would require no equipment additional to what is already planned and so is of inherently low-cost. It could be carried out by anyone having access to a laser or microwave ground station and a hydrogen maser.

A common structure for concepts of individuals, stuffs, and real kinds: more Mama, more milk, and more mouse.  

PubMed

Concepts are highly theoretical entities. One cannot study them empirically without committing oneself to substantial preliminary assumptions. Among the competing theories of concepts and categorization developed by psychologists in the last thirty years, the implicit theoretical assumption that what falls under a concept is determined by description ("descriptionism") has never been seriously challenged. I present a nondescriptionist theory of our most basic concepts, "substances," which include (1) stuffs (gold, milk), (2) real kinds (cat, chair), and (3) individuals (Mama, Bill Clinton, the Empire State Building). On the basis of something important that all three have in common, our earliest and most basic concepts of substances are identical in structure. The membership of the category "cat," like that of "Mama," is a natural unit in nature, to which the concept "cat" does something like pointing, and continues to point despite large changes in the properties the thinker represents the unit as having. For example, large changes can occur in the way a child identifies cats and the things it is willing to call "cat" without affecting the extension of its word "cat." The difficulty is to cash in the metaphor of "pointing" in this context. Having substance concepts need not depend on knowing words, but language interacts with substance concepts, completely transforming the conceptual repertoire. I will discuss how public language plays a crucial role in both the acquisition of substance concepts and their completed structure. PMID:10097011

Prognostic factors in multiple myeloma: definition of risk groups in 410 previously untreated patients: a Grupo Argentino de Tratamiento de la Leucemia Aguda study.  

PubMed

Four hundred ten previously untreated multiple myeloma patients entered onto two consecutive Grupo Argentino de Tratamiento de la Leucemia Aguda (GATLA) protocols were analyzed to identify significant prognostic factors influencing survival. The univariate analysis selected the following variables: performance status, renal function, percentage of bone marrow plasma cells at diagnosis, hemoglobin, and age. A multivariate analysis showed that performance status, renal function, percentage of bone marrow plasma cells, hemoglobin, and age were the best predictive variables for survival. A score was assigned to each patient according to these variables, which led to their classification in three groups: good, intermediate, and poor risk, with a probability of survival of 26% and 10% at 96 months, and 5% at 56 months, and median survival of 60, 37, and 14 months, respectively (P = .0000). In our patient population, this model proved to be superior to the Durie-Salmon staging system in defining prognostic risk groups, and separating patients with significantly different risks within each Durie-Salmon stage.

Human milk oligosaccharides: Every baby needs a sugar mama  

PubMed Central

Human milk oligosaccharides (HMOs) are a family of structurally diverse unconjugated glycans that are highly abundant in and unique to human milk. Originally, HMOs were discovered as a prebiotic “bifidus factor” that serves as a metabolic substrate for desired bacteria and shapes an intestinal microbiota composition with health benefits for the breast-fed neonate. Today, HMOs are known to be more than just “food for bugs”. An accumulating body of evidence suggests that HMOs are antiadhesive antimicrobials that serve as soluble decoy receptors, prevent pathogen attachment to infant mucosal surfaces and lower the risk for viral, bacterial and protozoan parasite infections. In addition, HMOs may modulate epithelial and immune cell responses, reduce excessive mucosal leukocyte infiltration and activation, lower the risk for necrotizing enterocolitis and provide the infant with sialic acid as a potentially essential nutrient for brain development and cognition. Most data, however, stem from in vitro, ex vivo or animal studies and occasionally from association studies in mother–infant cohorts. Powered, randomized and controlled intervention studies will be needed to confirm relevance for human neonates. The first part of this review introduces the pioneers in HMO research, outlines HMO structural diversity and describes what is known about HMO biosynthesis in the mother's mammary gland and their metabolism in the breast-fed infant. The second part highlights the postulated beneficial effects of HMO for the breast-fed neonate, compares HMOs with oligosaccharides in the milk of other mammals and in infant formula and summarizes the current roadblocks and future opportunities for HMO research.

GC-MS analysis of aroma of Medemia argun (mama-n-khanen or mama-n-xanin), an ancient Egyptian fruit palm.  

PubMed

The fruits of the edible and medicinal Egyptian palm, Medemia argun, were collected from Aswan in Egypt and the essential oil (EO) from fruits and headspace (HS) of the seeds and fleshy mesocarps were analyzed by GC and GC-MS. Results obtained by GC-MS analysis indicated a high variability in the oil and in the headspace from seeds and mesocarps. Sesquiterpene derivatives were the main group of volatiles in the EO from fruits and in the HS from seeds (45.0 and 64.0%, respectively), while oxygenated hydrocarbon derivatives were the main constituents in the HS obtained from fleshy mesocarps (96.5%). The different chemical composition of the headspace obtained from the seeds and mesocarps of M. argun can be correlated with the different roles that the different constituents play in the prevention of dehydration of the fruits in the desert region from where the plant was collected.

Jesus, Mama, and the constraints on salvific love in contemporary country music .  

PubMed

The discourse of contemporary country music creates a world permeated with religion and centered on the notion of salvific love. This form of salvation arises in the connection between people (or between people and God) and includes elements of sacrifice and transformation. Although highly conventional, country music must meet standards of 'authenticity' and 'relevance', which require the incorporation of contemporary American religious values (including self-love and self-actualization). An analysis of recent country music lyrics reveals the remarkable openness to new religious messages. However, the only acceptable messages are those that can be harmonized with the implicit Protestant Christian sensibility of the music. Salvific love, for this reason, is always heterosexual and at least compatible with a Christian message. While the music industry does its best to erase minority sexualities, the music itself is often surprisingly open to a queer interpretation. PMID:20681105

Mama's boy: sex differences in juvenile survival in a highly dimorphic large mammal, the Galapagos sea lion.  

PubMed

In many mammals, early survival differs between the sexes, with males proving the more fragile sex ["Fragile male (FM) hypothesis"], especially in sexually dimorphic species where males are the larger sex. Male-biased allocation (MBA) by females may offset this difference. Here, we evaluate support for the FM and MBA hypotheses using a dataset on Galapagos sea lions (Zalophus wollebaeki). We statistically model sex-specific survival as it depends on body mass and environmental conditions (sea surface temperature, SST, a correlate of marine productivity) at three developmental stages, the perinatal phase (1st month), the main lactation period (1st year), and the weaning period (2nd year). Supporting the FM hypothesis, we found that, early in life (1st month), at equal birth mass, males survived less well than females. During the remainder of the first year of life, male survival was actually less sensitive to harsh environmental conditions than that of females, contradicting the FM hypothesis and supporting the MBA hypothesis. During the second year of life, only male survival suffered with high SSTs as predicted by the FM hypothesis. At each developmental stage, observed survival rates were almost equal for both sexes, suggesting that mothers buffer against the inherent fragility of male offspring through increased allocation, thereby masking the differences in survival prospects between the sexes.

This manuscript focuses on qualitative data collected for AAKOMA Project, a 2-phase treatment engagement intervention trial for depressed African American adolescents and families. Data are presented from our phase I study of adult perspectives on African American adolescent depression, depression treatment, and research engagement. The research team conducted four focus groups (N = 24) and generated major themes from the data including ideas regarding the manifestations of depression in African American youth and psychosocial barriers to participation in depression research and treatment. Findings indicate that success in recruiting and retaining African American youth in depression research and treatment may include using innovative means to overcome the culturally embedded attributions of depression to non-biological causes, beliefs about the cultural insensitivity of treatments and challenges in the logistics of obtaining care. Adults report that encouraging youth and familial involvement in treatments and research should include targeted, community-partnered activities involving diverse staff in leadership roles and including community members as equal partners.

Identification and translational validation of novel mammaglobin-A CD8 T cell epitopes.  

PubMed

Mammaglobin-A (MAM-A) is a secretory protein that is overexpressed in 80 % of human breast cancers. Its near-universal expression in breast cancer as well as its exquisite tissue specificity makes it an attractive target for a breast cancer prevention vaccine, and we recently initiated a phase 1 clinical trial of a MAM-A DNA vaccine. Previously, we have identified multiple MAM-A CD8 T cell epitopes using a reverse immunology candidate epitope approach based on predicted binding, but to date no attempt has been made to identify epitopes using an unbiased approach. In this study, we used human T cells primed in vitro with autologous dendritic cells expressing MAM-A to systematically identify MAM-A CD8 T cell epitopes. Using this unbiased approach, we identified three novel HLA-A2-restricted MAM-A epitopes. CD8 T cells specific for these epitopes are able to recognize and lyse human breast cancer cells in a MAM-A-specific, HLA-A2-dependent fashion. HLA-A2(+)/MAM-A(+) breast cancer patients have an increased prevalence of CD8 T cells specific for these novel MAM-A epitopes, and vaccination with a MAM-A DNA vaccine significantly increases the number of these CD8 T cells. The identification and translational validation of novel MAM-A epitopes has important implications for the ongoing clinical development of vaccine strategies targeting MAM-A. The novel MAM-A epitopes represent attractive targets for epitope-based vaccination strategies, and can also be used to monitor immune responses. Taken together these studies provide additional support for MAM-A as an important therapeutic target for the prevention and treatment of breast cancer. PMID:25212176

DNA Methylation Impacts Gene Expression and Ensures Hypoxic Survival of Mycobacterium tuberculosis  

PubMed Central

DNA methylation regulates gene expression in many organisms. In eukaryotes, DNA methylation is associated with gene repression, while it exerts both activating and repressive effects in the Proteobacteria through largely locus-specific mechanisms. Here, we identify a critical DNA methyltransferase in M. tuberculosis, which we term MamA. MamA creates N6-methyladenine in a six base pair recognition sequence present in approximately 2,000 copies on each strand of the genome. Loss of MamA reduces the expression of a number of genes. Each has a MamA site located at a conserved position relative to the sigma factor ?10 binding site and transcriptional start site, suggesting that MamA modulates their expression through a shared, not locus-specific, mechanism. While strains lacking MamA grow normally in vitro, they are attenuated in hypoxic conditions, suggesting that methylation promotes survival in discrete host microenvironments. Interestingly, we demonstrate strikingly different patterns of DNA methyltransferase activity in different lineages of M. tuberculosis, which have been associated with preferences for distinct host environments and different disease courses in humans. Thus, MamA is the major functional adenine methyltransferase in M. tuberculosis strains of the Euro-American lineage while strains of the Beijing lineage harbor a point mutation that largely inactivates MamA but possess a second functional DNA methyltransferase. Our results indicate that MamA influences gene expression in M. tuberculosis and plays an important but strain-specific role in fitness during hypoxia. PMID:23853579

The construction and modes of operation of Multi-Anode Microchannel Arrays (MAMA's) are briefly reviewed. The MAMA detectors, which are a family of photoelectric, photon-counting array detectors being developed specifically for use in instruments on ground-based and space-borne telescopes, combine the high sensitivity and photometric stability of a conventional channel electron multiplier with a high-resolution imaging capability. The MAMA detectors feature low applied potential (less than 3 kV), high gain (greater than 10 to the 6th electrons/pulse), an absolute event timing accuracy of 100 ns or better, a very long count lifetime (greater than 2.5 x 10 to the 11th counts/sq mm), and a power consumption of less than 30 W for a complete system

Testing road surface treatments to reduce erosion in forest roads in Honduras [Tratamientos de la superfi cie de rodadura para reducir la erosi??n en caminos forestales en Honduras  

USGS Publications Warehouse

Testing road surface treatments to reduce erosion in forest roads in Honduras. Cien. Inv. Agr. 36(3):425-432. Using forest roads produces more erosion and sedimentation than any other forest or agricultural activity. This study evaluated soil losses from a forest road in central Honduras over two consecutive years. We divided a 400-m segment of road into 8 experimental units, each 50 m in length. Four units were treated with Best Management Practices (BMPs) and four were left untreated. The BMP treatments included reshaping the road prism, installing culverts and reshaping of road ditches, compacting 20-cm layers of the road tread, crowning the road surface (3% slope, double drainage), longitudinal sloping (less than 12%), and adding a 10-cm layer of gravel (crush size = 0.63 cm). Soil movement was measured daily during the rainy seasons. The highest soil loss occurred in the control road, around 500 m3 km-1 per year, while the road treated with BMP lost approximately 225 m3km-1 per year. These results show that road surface erosion can be reduced up to 50% with the implementation of surface treatments.

Loss-of-function and gain-of-function phenotypes of stomatocytosis mutant RhAG F65S  

PubMed Central

Four patients with overhydrated cation leak stomatocytosis (OHSt) exhibited the heterozygous RhAG missense mutation F65S. OHSt erythrocytes were osmotically fragile, with elevated Na and decreased K contents and increased cation channel-like activity. Xenopus oocytes expressing wild-type RhAG and RhAG F65S exhibited increased ouabain and bumetanide-resistant uptake of Li+ and 86Rb+, with secondarily increased 86Rb+ influx sensitive to ouabain and to bumetanide. Increased RhAG-associated 14C-methylammonium (MA) influx was severely reduced in RhAG F65S-expressing oocytes. RhAG-associated influxes of Li+, 86Rb+, and 14C-MA were pharmacologically distinct, and Li+ uptakes associated with RhAG and RhAG F65S were differentially inhibited by NH4+ and Gd3+. RhAG-expressing oocytes were acidified and depolarized by 5 mM bath NH3/NH4+, but alkalinized and depolarized by subsequent bath exposure to 5 mM methylammonium chloride (MA/MA+). RhAG F65S-expressing oocytes exhibited near-wild-type responses to NH4Cl, but MA/MA+ elicited attenuated alkalinization and strong hyperpolarization. Expression of RhAG or RhAG F65S increased steady-state cation currents unaltered by bath Li+ substitution or bath addition of 5 mM NH4Cl or MA/MA+. These oocyte studies suggest that 1) RhAG expression increases oocyte transport of NH3/NH4+ and MA/MA+; 2) RhAG F65S exhibits gain-of-function phenotypes of increased cation conductance/permeability, and loss-of-function phenotypes of decreased and modified MA/MA+ transport, and decreased NH3/NH4+-associated depolarization; and 3) RhAG transports NH3/NH4+ and MA/MA+ by distinct mechanisms, and/or the substrates elicit distinct cellular responses. Thus, RhAG F65S is a loss-of-function mutation for amine transport. The altered oocyte intracellular pH, membrane potential, and currents associated with RhAG or RhAG F65S expression may reflect distinct transport mechanisms. PMID:21849667

A series of novel taxane-based multidrug resistance (MDR) reversal agents (TRAs) has been designed and synthesized. Structure-activity relationship (SAR) study clearly indicates that modification of the C-7 position with hydrophobic arenecarbonylcinnamoyl groups brings about high potency against drug efflux mediated by P-glycoprotein (P-gp). Six TRAs exhibit ability to modulate a wide range of ATP-binding cassette (ABC) transporters, such as P-gp, multidrug resistance-associated protein 1 (MRP1), and breast cancer resistance protein (BCRP), which may serve as novel broad-spectrum modulators of ABC transporters.

Relationships between plasma and erythrocyte Zn and maturation in adolescent males  

SciTech Connect

Sixty-three male volunteers between the ages of 10.6 and 14.3 yr were assessed for maturation and zinc status. The adrenal androgen dehydroepiandrosterone sulfate (DHEAS), used as a maturation indicator, was significantly correlated with height, weight, hemoglobin, and mid-arm muscle area (MAMA) as previously reported. Erythrocyte Zn (RBC-Zn) and plasma Zn were significantly correlated. When grouped by plasma Zn tertiles, significant differences were found for RBC-Zn and cholesterol between the highest and lowest groups. When subjects were grouped by RBC-Zn concentration, the lowest 10% of subjects had higher concentrations of DHEAS, lower plasma Zn , and were taller, heavier and had larger MAMA than the other group. In these subjects plasma and RBC-Zn concentrations were within normal limits. In this study RBC-Zn and plasma Zn were related to indicators of maturation.

A new strategy and its effect on adherence to intermittent preventive treatment of malaria in pregnancy in Uganda  

PubMed Central

Background Few women in Uganda access intermittent preventive treatment of malaria in pregnancy (IPTp) with sulfadoxine-pyrimethamine (SP). Previous studies have shown that high costs, frequent stock-out of drugs, supplies and poor quality of care are the greatest hindrance for women to access health services. In order to increase adherence to IPTp, we conceptualised an intervention that offset delivery care costs through providing a mama kit, created awareness on health benefits of IPTp and built trust between the provider and the client. Methods The new strategy was conceived along four constructs namely: 1) creating awareness by training midwives to explain the benefits of SP and the importance of adhering to the two doses of SP as IPTp to all pregnant women who attended ANC and consented to the study. Midwives were trained for two days in customer care and to provide a friendly environment. The pregnant women were also informed of the benefits of attending ANC and delivering at health facilities. 2) Each woman was promised a mama kit during ANC; 3) trust was built by showing the mama kit to each woman and branding it with her name; 4) keeping the promise by providing the mama kit when women came to deliver. The strategy to increase adherence to two doses of SP and encourage women to deliver at health facilities was implemented at two health facilities in Mukono district (Kawolo hospital and Mukono health centre IV). The inclusion criteria were women who: i) consented to the study and ii) were in the second trimester of pregnancy. All pregnant women in the second trimester (4-6 months gestation) who attended ANC and consented to participate in the study were informed of the benefits of SP, the importance of delivering at health facilities, were advised to attend the scheduled visits, promised a mama kit and ensured the kit was available at delivery. The primary outcome was the proportion of pregnant women adhering to a two dose SP regimen. Results A total of 2,276 women received the first dose of SP and 1,656 (72.8%) came back for the second dose. 1,069 women were involved in the evaluation (384 had participated in the intervention while 685 had not). The main reasons that enabled those who participated in the intervention to adhere to the two doses of IPTp and deliver at the study facilities were: an explanation provided on the benefits of IPTp and delivering at health facilities (25.1%), availability of a mama kit at delivery (24.6%), kind midwives (19.8%) and fearing complications of pregnancy (8.5%). Overall, 78.0% of these women reported that they were influenced to adhere to IPTp by the intervention. In a multivariable regression, nearby facility, P?=?0. 007, promising a mama kit, P?=?0.002, kind midwives, P?=?0.0001 and husbands’ encouragement, P?=?0.0001 were the significant factors influencing adherence to IPTp with SP. Conclusion The new strategy was a good incentive for women to attend scheduled ANC visits, adhere to IPTp and deliver at the study facilities. Policy implications include the urgent need for developing a motivation package based on the Health-Trust Model to increase access and adherence to IPTp. PMID:24053142

Taxane-based reversal agents modulate drug resistance mediated by P-glycoprotein, multidrug resistance protein, and breast cancer resistance protein.  

PubMed

Overexpression of ATP-binding cassette transport proteins, including P-glycoprotein (Pgp), multidrug resistance (MDR) protein (MRP-1), and breast cancer resistance protein (BCRP), is a well-characterized mechanism of MDR in tumor cells. Although the cytotoxic taxanes paclitaxel and docetaxel are substrates for Pgp-mediated efflux, the semisynthetic taxane analogue ortataxel inhibits drug efflux mediated by Pgp as well as, as we recently demonstrated, MRP-1 and BCRP. Nevertheless, ortataxel is not optimal for development as a clinical MDR modulator because of its cytotoxicity [corrected]. We sought to identify noncytotoxic taxane-based broad-spectrum modulators from a library of noncytotoxic taxane-based reversal agents (tRAs) designed by eliminating the C-13 side chain of the taxane molecule, which inhibits microtubule depolymerization. Twenty tRAs, selected based on modulation of paclitaxel cytotoxicity in Pgp-overexpressing MDA435/LCC6(mdr1) cells, were studied for modulation of retention and cytotoxicity of substrates of MRP-1 and BCRP as well as Pgp in established cell lines overexpressing each of these transporters. Four tRAs modulated MRP-1 and 17 modulated BCRP in addition to Pgp. The four broad-spectrum tRAs strongly modulated daunorubicin and mitoxantrone efflux and enhanced their cytotoxicity in cell lines overexpressing the three MDRs, decreasing IC(50) values by as much as 97% [corrected]. These tRAs, especially tRA 98006, have promise for development as clinical broad-spectrum MDR modulators and warrant more preclinical analysis to determine pharmacokinetic interactions and efficacy.

Getting TRAIL back on track for cancer therapy  

PubMed Central

Unlike other members of the TNF superfamily, the TNF-related apoptosis-inducing ligand (TRAIL, also known as Apo2L) possesses the unique capacity to induce apoptosis selectively in cancer cells in vitro and in vivo. This exciting discovery provided the basis for the development of TRAIL-receptor agonists (TRAs), which have demonstrated robust anticancer activity in a number of preclinical studies. Subsequently initiated clinical trials testing TRAs demonstrated, on the one hand, broad tolerability but revealed, on the other, that therapeutic benefit was rather limited. Several factors that are likely to account for TRAs' sobering clinical performance have since been identified. First, because of initial concerns over potential hepatotoxicity, TRAs with relatively weak agonistic activity were selected to enter clinical trials. Second, although TRAIL can induce apoptosis in several cancer cell lines, it has now emerged that many others, and importantly, most primary cancer cells are resistant to TRAIL monotherapy. Third, so far patients enrolled in TRA-employing clinical trials were not selected for likelihood of benefitting from a TRA-comprising therapy on the basis of a valid(ated) biomarker. This review summarizes and discusses the results achieved so far in TRA-employing clinical trials in the light of these three shortcomings. By integrating recent insight on apoptotic and non-apoptotic TRAIL signaling in cancer cells, we propose approaches to introduce novel, revised TRAIL-based therapeutic concepts into the cancer clinic. These include (i) the use of recently developed highly active TRAs, (ii) the addition of efficient, but cancer-cell-selective TRAIL-sensitizing agents to overcome TRAIL resistance and (iii) employing proteomic profiling to uncover resistance mechanisms. We envisage that this shall enable the design of effective TRA-comprising therapeutic concepts for individual cancer patients in the future. PMID:24948009

Air and biological monitoring of toluene diisocyanate in a flexible foam plant.  

PubMed

Comparative air measurements of toluene diisocyanate (TDI) were performed in a 5.6 m3 standard atmosphere and at a TDI flexible foam plant. Air samples were collected in midget impinger flasks containing 9-(N-methyl-amino-methyl)-anthracene (MAMA) in toluene and on 13-mm glass-fiber filters impregnated with MAMA and glycerol analyzed by LC-UV and with filter-tape instruments. In the laboratory study the average amounts of the TDI-MAMA derivatives determined were higher for filters compared to impingers when tested at concentrations between 16 and 150 micrograms/m3 (n = 29). At the TDI foaming plant the amount of TDI-MAMA collected on the filters compared with impingers showed higher TDI values at low concentrations and lower values at higher concentrations. The same was seen for the filter-tape measurements, but for two samples at very low concentrations the response was much lower. The average air concentration was 29.8 micrograms/m3 (12.5-79.9; n = 12). The highest exposure peak measured was approximately 3 mg TDI/m3. 2,4- and 2,6-toluene diamine (TDA) in urine (U-TDA) and in plasma (P-TDA) from four exposed workers and one volunteer were determined after strong acid hydrolysis as their pentafluoro-propionic anhydride derivatives using gas chromatography-mass spectrometry. The ions monitored were the M-20 ions (M = molecular weight) of the TDA and trideuterium labeled TDA as the internal standard. The P-TDA among the workers varied between 1-38 micrograms/L and between 7-24 micrograms/L for 2,4- and 2,6-TDA, respectively. The individual plasma levels among the workers over the 3-day periods varied between 7-73%. For the volunteer, P-TDA reached a maximum about 24 hours after the last exposure. The half-time of P-TDA for the volunteer was about 10 days. The urine levels (U-TDA) varied greatly with time and exposure. High peaks were found during or shortly after the exposure. No clear correlation between air levels of TDI measured with the filter-tape instruments and levels of TDA in hydrolyzed urine and plasma was seen, but the U-TDAMax followed the exposure in time as measured with the filter-tape instruments.

Detection and differentiation of CVI988 (Rispens vaccine) from other serotype 1 Marek's disease viruses.  

PubMed

The serotype 1 Marek's disease virus (MDV) is the causative agent for Marek's disease (MD), a lymphoproliferative disease of chickens of great concern to the poultry industry. CVI988 (Rispens vaccine), an attenuated serotype 1 MDV, is currently the most efficacious commercially available vaccine for preventing MD. However, it is difficult to detect and differentiate CVI988 when other serotype 1 MDVs are present. To facilitate the detection of CVI988, we developed two sets of primers for a mismatch amplification mutation assay (MAMA) PCR that targeted the single nulceotide polymorphism associated with the H19 epitope of the phosphorylated protein 38 gene. The PCR was very specific. One primer set (oncogenic primers) amplified DNA from 15 different serotype 1 MDVs except CVI988. The other primer set (CVI988 primers) amplified DNA from CVI988 but not from any of the other 15 serotype 1 MDVs. A real-time PCR assay was developed using MAMA primers, and specificity and sensitivity was evaluated in vitro and in vivo. Mixtures of plasmids (CVI988 plasmid and oncogenic plasmid) at various concentrations were used to evaluate the sensitivity/specificity of MAMA primers in vitro. Both primer setswere able to amplify as little as one copy of their respective plasmid. Oncogenic primers were highly specific and only amplified CVI988 plasmid when the concentration of oncogenic plasmid was very low (1 X 10(1)) and CVI988 plasmid was very high (1 X 10(6)). Specificity of CVI988 primers was not as high because they could amplify oncogenic plasmids when the concentration of CVI988 plasmid was 1 x 10(3) and the concentration of oncogenic 1 x 10(2). Validation of MAMA primers in in vivo samples demonstrated that oncogenic primers can be used for both early diagnosis of MD in feather pulp (FP) samples collected at 3 wk of age and confirmation of MD diagnosis in tumors. CVI988 primers could be used to monitor CVI988 vaccination in samples with a low load of oncogenic MDV DNA (latently infected samples or negative) but not in samples with a high load of oncogenic MDV DNA (tumors). Our results suggest that monitoring CVI988 vaccination in FP samples collected at 1 wk of age ensures the specificity of the CVI988 primers. PMID:25055627

Asiddhatva Principle in Computational Model of A???dhy?y?  

NASA Astrophysics Data System (ADS)

P??ini's A???dhy?y? can be thought of as an automaton to generate Sanskrit words and sentences. A???dhy?y? consists of s?tras that are organized in a systematic manner. The words are derived from the roots and affixes by the application of these s?tras that follow a well defined procedure. Therefore, A???dhy?y? is best suited for computational modeling. A computational model with conflict resolution techniques was discussed by us (Sridhar et al, 2009)[12]. In continuation with that, this paper presents, an improvised computational model of A???dhy?y?. This model is further developed based on the principle of asiddhatva. A new mathematical technique called 'filter' is introduced to comprehensively envisage all usages of asiddhatva in A???dhy?y?.

Atlantic Leatherback Migratory Paths and Temporary Residence Areas  

PubMed Central

Background Sea turtles are long-distance migrants with considerable behavioural plasticity in terms of migratory patterns, habitat use and foraging sites within and among populations. However, for the most widely migrating turtle, the leatherback turtle Dermochelys coriacea, studies combining data from individuals of different populations are uncommon. Such studies are however critical to better understand intra- and inter-population variability and take it into account in the implementation of conservation strategies of this critically endangered species. Here, we investigated the movements and diving behaviour of 16 Atlantic leatherback turtles from three different nesting sites and one foraging site during their post-breeding migration to assess the potential determinants of intra- and inter-population variability in migratory patterns. Methodology/Principal Findings Using satellite-derived behavioural and oceanographic data, we show that turtles used Temporary Residence Areas (TRAs) distributed all around the Atlantic Ocean: 9 in the neritic domain and 13 in the oceanic domain. These TRAs did not share a common oceanographic determinant but on the contrary were associated with mesoscale surface oceanographic features of different types (i.e., altimetric features and/or surface chlorophyll a concentration). Conversely, turtles exhibited relatively similar horizontal and vertical behaviours when in TRAs (i.e., slow swimming velocity/sinuous path/shallow dives) suggesting foraging activity in these productive regions. Migratory paths and TRAs distribution showed interesting similarities with the trajectories of passive satellite-tracked drifters, suggesting that the general dispersion pattern of adults from the nesting sites may reflect the extent of passive dispersion initially experienced by hatchlings. Conclusions/Significance Intra- and inter-population behavioural variability may therefore be linked with initial hatchling drift scenarios and be highly influenced by environmental conditions. This high degree of behavioural plasticity in Atlantic leatherback turtles makes species-targeted conservation strategies challenging and stresses the need for a larger dataset (>100 individuals) for providing general recommendations in terms of conservation.

Altered Expression of Autoimmune Regulator in Infant Down Syndrome Thymus, a Possible Contributor to an Autoimmune Phenotype  

PubMed Central

Down syndrome (DS), caused by trisomy of chromosome 21, is associated with immunological dysfunctions such as increased frequency of infections and autoimmune diseases. Patients with DS share clinical features, such as autoimmune manifestations and specific autoantibodies, with patients affected by autoimmune polyendocrine syndrome type 1. Autoimmune polyendocrine syndrome type 1 is caused by mutations in the autoimmune regulator (AIRE) gene, located on chromosome 21, which regulates the expression of tissue-restricted Ags (TRAs) in thymic epithelial cells. We investigated the expression of AIRE and TRAs in DS and control thymic tissue using quantitative PCR. AIRE mRNA levels were elevated in thymic tissue from DS patients, and trends toward increased expression of the AIRE-controlled genes INSULIN and CHRNA1 were found. Immunohistochemical stainings showed altered cell composition and architecture of the thymic medulla in DS individuals with increased frequencies of AIRE-positive medullary epithelial cells and CD11c-positive dendritic cells as well as enlarged Hassall’s corpuscles. In addition, we evaluated the proteomic profile of thymic exosomes in DS individuals and controls. DS exosomes carried a broader protein pool and also a larger pool of unique TRAs compared with control exosomes. In conclusion, the increased AIRE gene dose in DS could contribute to an autoimmune phenotype through multiple AIRE-mediated effects on homeostasis and function of thymic epithelial cells that affect thymic selection processes.

Real-time PCR assays for genotyping of Cryptococcus gattii in North America  

PubMed Central

Background Cryptococcus gattii has been the cause of an ongoing outbreak starting in 1999 on Vancouver Island, British Columbia and spreading to mainland Canada and the US Pacific Northwest. In the course of the outbreak, C. gattii has been identified outside of its previously documented climate, habitat, and host disease. Genotyping of C. gattii is essential to understand the ecological and geographical expansion of this emerging pathogen. Methods We developed and validated a mismatch amplification mutation assay (MAMA) real-time PCR panel for genotyping C. gattii molecular types VGI-VGIV and VGII subtypes a,b,c. Subtype assays were designed based on whole-genome sequence of 20 C. gattii strains. Publically available multilocus sequence typing (MLST) data from a study of 202 strains was used for the molecular type (VGI-VGIV) assay design. All assays were validated across DNA from 112 strains of diverse international origin and sample types, including animal, environmental and human. Results Validation revealed each assay on the panel is 100% sensitive, specific and concordant with MLST. The assay panel can detect down to 0.5 picograms of template DNA. Conclusions The (MAMA) real-time PCR panel for C. gattii accurately typed a collection of 112 diverse strains and demonstrated high sensitivity. This is a time and cost efficient method of genotyping C. gattii best suited for application in large-scale epidemiological studies. PMID:24886039

Thermal motion of the STIS optical bench  

NASA Technical Reports Server (NTRS)

Various tests have been done of the Space Telescope Imaging Spectrograph (STIS) using internal wavecals to measure thermal motion of the spectral format on the detectors. In most cases, the spectral format moves less than the specification not to exceed 0.2 pixels per hour. Primary causes of the motion are (1) changes to the thermal design dictated by the warmer Aft Shroud environment and (2) on-orbit power cycling of Multi-Anode Microchannel Arrays (MAMA) electronics to minimize the effects of radiation hits on the MAMA detectors. The rear portion of the STIS optical bench is too warm to be held at a constant temperature by internal heaters. Electronics swing in temperature with an orbital and daily frequency. The thermal drift of the optical formats is not negligible, but is well behaved in most circumstances. The observer is advised to examine the trade-off between the most accurate wavelengths with best spectral/spatial resolutions versus increased overheads that directly affect the observing times. A long term concern is that the Aft Shroud thermal environment is predicted to heat up as much as one Centigrade degree per year. Progressively more of the bench would move out of thermal control. Thus the external cooler for STIS, being considered for the Third Servicing Mission is of major importance to the long term operation of STIS.

Hubble Space Telescope and Ground-Based Optical and Ultraviolet Observations of GRB010222  

E-print Network

We report on Hubble Space Telescope WFPC2 optical and STIS near ultraviolet MAMA observations, and ground-based optical observations of GRB010222, spanning 15 hrs to 71 days. The observations are well-described by a relativistic blast-wave model with a hard electron-energy distribution, p = 1.57, and a jet transition at t_j=0.93 days. These values are slightly larger than previously found as a result of a correction for the contribution from the host galaxy to the late-time ground-based observations and the larger temporal baseline provided by the Hubble Space Telescope observations. The host galaxy is found to contain a very compact core (size <0.25 arcsec) which coincides with the position of the optical transient. The STIS near ultraviolet MAMA observations allow for an investigation of the extinction properties along the line of sight to GRB010222. We find that the far ultraviolet curvature component (c_4) is rather large. In combination with the low optical extinction A_V =0.11 mag, when compared to the Hydrogen column inferred from X-ray observations, we suggest that this is evidence for dust destruction.

High resolution decoding of Multi-Anode Microchannel Array detectors  

NASA Astrophysics Data System (ADS)

The Multi-Anode Microchannel Array (MAMA) is a photon counting detector which utilizes a photocathode for photon to electron conversion, a microchannel plate (MCP) for signal amplification and a proximity focused anode array for position sensitivity. The detector electronics decode the position of an event through coincidence discrimination. The decoding algorithm which associates a given event with the appropriate pixel is determined by the geometry of the array. A new algorithm incorporated into a CMOS Application Specific Integrated Circuit (ASIC) decoder which improves the pixel spatial resolution is described. The new algorithm does not degrade the detector throughput and does not require any modifications to the detector tube. The standard MAMA detector has a pixel size of 25 x 25 square microns, but with the new decoder circuit the pixel size is reduced to 12.5 x 12.5 square microns. We have built the first set of decode electronics utilizing the new ASIC chips and report here on the first imaging tests of this system.

An Asic for High-Speed and High-Resolution Decoding of Multi-Anode Microchannel Array Detectors  

NASA Astrophysics Data System (ADS)

The Multi-Anode Microchannel Array (MAMA) is a microchannel plate-based photon-counting detector with applications in ground-based and space-based astronomy. The detector requires a digital decoder to determine the position of each photon event, and the decoding algorithm that associates a given event with the appropriate pixel is determined by the geometry of the detector's anode array. An Application Specific Integrated Circuit (ASIC) version of a MAMA decoder, suitable for both ground-based and space-based applications, has been designed, fabricated and tested successfully. The design was fabricated in commercial 1.5 micron CMOS gate array technology, and the chip is smaller, faster, incorporates more options and uses less power than comparable discrete component decoders. The chip has performed well in preliminary radiation exposure tests and incorporates a new high resolution decoding algorithm that has the potential to double the detector's spatial resolution. The performance of a new high resolution algorithm has been demonstrated. The algorithm does not degrade the pulse-pair resolution of the detector; moreover, it requires no modifications to the detector tube. Besides improving image quality, high resolution decoding has the potential to lower power consumption and increase the detector signal-to-noise ratio. In addition, high resolution decoding allows the use of smaller telescopes while still preserving detector resolution, thereby decreasing satellite payload size and weight. Detector response measurements demonstrate that high resolution decoding yields at least a 60% enhancement in spatial resolution with a 25 micron MAMA detector. Detector response models which assume a Gaussian pixel response function for both low and high resolution pixels have been shown to match the actual measured detector response to within 9%. High resolution decoding is robust; variations in detector operating parameters produced at most a 6% difference in spatial resolution. Measurements of detector response indicate that the spatial resolution achieved by the high resolution decoding algorithm depends primarily on the microchannel plate pore resolution. Other parameters were found to have only second order effects on the spatial resolution. Detector responses of both the low resolution decoding and high resolution decoding algorithms display excellent temporal stability.

Targeting FtsZ for antituberculosis drug discovery: noncytotoxic taxanes as novel antituberculosis agents.  

PubMed

Screening of 120 taxanes identified a number of compounds that exhibited significant antituberculosis activity. Rational optimization of selected compounds led to the discovery that the C-seco-taxane-multidrug-resistance (MDR) reversal agents (C-seco-TRAs) are noncytotoxic at the upper limit of solubility and detection (>80 microM), while maintaining MIC(99) values of 1.25-2.5 microM against drug-resistant and drug-sensitive strains of Mycobacterium tuberculosis (MTB). Treatment of MTB cells with TRA 3aa and 10a at the MIC caused filamentation and prolongation of the cells, a phenotypic response to FtsZ inactivation. PMID:16420032

Galaxy evolution at low redshift? -- I. Optical counts  

E-print Network

We present bright galaxy number counts in the blue (16MAMA machine, and individually calibrated using an adequate number of CCD sequences. We find a relatively large density of bright galaxies implying a ``high'' normalization of the local luminosity function. Our counts and colour distributions exhibit no large departure from what standard no-evolution models predict to magnitudes Bj<21, removing the need for evolution of the non-dwarf galaxy population in the optical, out to z # 0.2. This result disagrees with that of Maddox et al. (1990) on the APM catalog. We show that the APM and similar catalogs may be affected by a systematic magnitude scale error which would explain this discrepancy.

A digital autoradiography system based on the Medipix2 chip: images of 3H and 14C microscales  

NASA Astrophysics Data System (ADS)

In the framework of the MAMA project, funded by INFN, we have assembled a digital imaging system for beta and gamma autoradiography based on the Medipix2 single photon counting read-out chip bump-bonded to a 300 ?m thick silicon pixel detector. This system has 256×256 square pixels of 55 ?m pitch for a total sensitive area of 14×14 mm 2. Each pixel contains two discriminators and a 13-bit counter. The detection threshold is about 6 keV and a noise is about 10 -3 cps/mm 2. Real time images have been obtained of 3H and 14C autoradiographic scales. The minimum detectable activity is 0.32 Bq in 14 h for 3H and 0.012 Bq in 10 h for 14C.

Multidisciplinary collaborative development of a plain-language prenatal education book.  

PubMed

During pregnancy, women actively seek out health information that promotes the well-being of themselves and their fetuses. For those with health literacy challenges, access to understandable health information can be difficult. Written information, in particular, needs to be readable and usable by the women served. Plain language is an essential component of effective health education material. In an effort to create standardized prenatal education materials for a diverse population of childbearing women, Boston Medical Center's midwifery service led a multidisciplinary initiative to develop a comprehensive plain-language prenatal education book. Midwives, obstetricians, family physicians, nurses, and community doulas contributed to the content of the book; art students provided graphic design skills; and a literacy consultant assisted in the wording and layout. The Hey Mama! book provides women with woman-centered, readable, comprehensive information about pregnancy, labor, postpartum, and newborn care. PMID:23647968

The explosion of Information Technology (IT) in the commercial sector in the 1990's has led to billion dollar corporations overtaking the US Government (e.g., DARPA, NSF) as the leaders in IT research and development. The tenacity of the IT industry in accelerating technology development, in response to commercial demands, has actually provided government organizations with a unique opportunity to incorporate robust commercial IT into their individual applications. This development allows government agencies to focus their limited funds on the application aspects of their problems by leveraging commercial information technology developments. This paradigm applies directly to counterdrug enforcement and support. This paper describes a system that applies the state-of-the-art in information technology to news and information exploitation to produce a Multi-media Agent Monitoring and Assessment (MAMA) system capable of tracking information for field agent use, identifying assets of organizations and individuals for seizure, and disrupting drug shipping routes.

Evaluation of water quality parameters for the Mamasin dam in Aksaray City in the central Anatolian part of Turkey by means of artificial neural networks  

NASA Astrophysics Data System (ADS)

Sustaining the human ecological benefits of surface water requires carefully planned strategies for reducing the cumulative risks posed by diverse human activities. The municipality of Aksaray city plays a key role in developing solutions to surface water management and protection in the central Anatolian part of Turkey. The responsibility to provide drinking water and sewage works, regulate the use of private land and protect public health provides the mandate and authority to take action. The present approach discusses the main sources of contamination and the result of direct wastewater discharges into the Melendiz and Karasu rivers, which recharge the Mamas?n dam sites by the use of artificial neural network (ANN) modeling techniques. The present study illustrates the ability to predict and/or approve the output values of previously measured water quality parameters of the recharge and discharge areas at the Mamasin dam site by means of ANN techniques. Using the ANN model is appreciated in such environmental research. Here, the ANN is used for estimating if the field parameters are agreeable to the results of this model or not. The present study simulates a situation in the past by means of ANN. But in case any field measurements of some relative parameters at the outlet point “discharge area” have been missed, it could be possible to predict the approximate output values from the detailed periodical water quality parameters. Because of the high variance and the inherent non-linear relationship of the water quality parameters in time series, it is difficult to produce a reliable model with conventional modeling approaches. In this paper, the ANN modeling technique is used to establish a model for evaluating the change in electrical conductivity (EC) and dissolved oxygen (DO) values in recharge (input) and discharge (output) areas of the dam water under pollution risks. A general ANN modeling scheme is also recommended for the water parameters. The modeling process includes four main stages: (1) source data analysis, (2) system priming, (3) system fine-tuning and (4) model evaluation. Results of the ANN modeling scheme indicate that the output values are agreeable to the water quality parameters, which were measured at the field in the static water mass of the Mamas?n dam lake. Water contamination at the dam site is caused by the continuous increase of nutrient contents and decrease of the O2 level in water causing an anaerobic condition. It may stimulate algae growth flow in such water bodies, consequently reducing water quality.

Models of Aire-Dependent Gene Regulation for Thymic Negative Selection  

PubMed Central

Mutations in the autoimmune regulator (AIRE) gene lead to autoimmune polyendocrinopathy syndrome type 1 (APS1), characterized by the development of multi-organ autoimmune damage. The mechanism by which defects in AIRE result in autoimmunity has been the subject of intense scrutiny. At the cellular level, the working model explains most of the clinical and immunological characteristics of APS1, with AIRE driving the expression of tissue-restricted antigens (TRAs) in the epithelial cells of the thymic medulla. This TRA expression results in effective negative selection of TRA-reactive thymocytes, preventing autoimmune disease. At the molecular level, the mechanism by which AIRE initiates TRA expression in the thymic medulla remains unclear. Multiple different models for the molecular mechanism have been proposed, ranging from classical transcriptional activity, to random induction of gene expression, to epigenetic tag recognition effect, to altered cell biology. In this review, we evaluate each of these models and discuss their relative strengths and weaknesses. PMID:22566805

Structure and Biological Activities of Beta Toxin from Staphylococcus aureus? †  

PubMed Central

Beta toxin is a neutral sphingomyelinase secreted by certain strains of Staphylococcus aureus. This virulence factor lyses erythrocytes in order to evade the host immune system as well as scavenge nutrients. The structure of beta toxin was determined at 2.4-Å resolution using crystals that were merohedrally twinned. This structure is similar to that of the sphingomyelinases of Listeria ivanovii and Bacillus cereus. Beta toxin belongs to the DNase I folding superfamily; in addition to sphingomyelinases, the proteins most structurally related to beta toxin include human endonuclease HAP1, Escherichia coli endonuclease III, bovine pancreatic DNase I, and the endonuclease domain of TRAS1 from Bombyx mori. Our biological assays demonstrated for the first time that beta toxin kills proliferating human lymphocytes. Structure-directed active site mutations show that biological activities, including hemolysis and lymphotoxicity, are due to the sphingomyelinase activity of the enzyme. PMID:17873030

The COS calibration pipeline and verification process  

NASA Astrophysics Data System (ADS)

The Cosmic Origins Spectrograph,1 COS, will be installed in the Hubble Space Telescope (HST) during the next servicing mission. This will be the most sensitive ultraviolet spectrograph ever flown aboard the HST. The calibration pipeline (CALCOS), written in Python, has been developed by the Space Telescope Science Institute (STScI) to support the calibration of HST/COS data. As with other HST pipelines, CALCOS uses an association table to specify the data files to be included, and employs header keywords to specify the calibration steps to be performed and the reference files to be used. CALCOS is designed with a common underlying structure for processing far ultraviolet (FUV) and near ultraviolet (NUV) channels which, respectively, use a cross delay line and a Multi Anode Microchannel Array (MAMA) detector. The pipeline basics and channel dependent specifics are presented. The generation and application of the current reference files, derived from ground-based calibration data, is described, along with the pipeline verification process and results. The CALCOS calibration includes pulse-height filtering and geometric correction for the FUV channel; flat-field, deadtime, and Doppler correction for both channels. Methods for obtaining an accurate wavelength calibra-tion using the on-board spectral line lamp are described. The instrument sensitivity is applied to the background corrected spectrum to produce the final flux calibrated spectrum.

Using STIS to find gamma-ray burst redshifts  

NASA Astrophysics Data System (ADS)

A recent spectrum of the optical afterglow of GRB 970508 suggests that gamma-ray bursts (GRBs) are cosmological in origin, and it is of crucial importance to derive an accurate distance to each burst. If GRBs occur near their host galaxies (much less than 40 kpc) then Lyman limit absorption should be observable in roughly half the GRB afterglow spectra. Here we outline the methodology to obtain a redshift from the GRB afterglow spectrum using the recently installed Space Telescope Imaging Spectrograph (STIS) instrument on board HST. A low-resolution spectrum with the Multi-Anode Microchannel Array (MAMA) detector gives complete spectral coverage over the wavelength range 1570-3180 A and 1150-1740 A. Assuming that a Target of Opportunity observation is conducted soon (about 3 wk) after a bright burst, a relatively small integration time (about three orbits) would be sufficient to detect the Lyman limit over a wide redshift range (0.3-2.2). Detection (or nondetection) of the Lyman limit, in concert with ground-based observations of nearby galaxies and Mg II and C IV absorption lines, should provide meaningful constraints on the relationship of GRBs to galaxies.

Large outbreak of cholera caused by El Tor variant Vibrio cholerae O1 in the eastern coast of Odisha, India during 2009.  

PubMed

A large outbreak of cholera reported during April-July 2009 in the Kendrapada district of Odisha, India was investigated. Forty-one rectal swabs and 41 water samples, collected from diarrhoeal patients and from different villages were bacteriologically analysed for the isolation of bacterial enteriopathogens, antibiogram profile and detection of various toxic genes. The bacteriological analysis of rectal swabs and environmental water samples revealed the presence of V. cholerae O1 Ogawa biotype El Tor. The V. cholerae strains were resistant to ciprofloxacin, co-trimoxazole, chloramphenicol, streptomycin, ampicillin, furazolidone and nalidixic acid. The multiplex polymerase chain reaction (PCR) assay on V. cholerae strains revealed the presence of ctxA and tcpA genes. The mismatch amplification of mutation assay (MAMA) PCR on clinical and environmental isolates of V. cholerae revealed that the strains were El Tor biotype, which harboured the ctxB gene of the classical strain. The random amplified polymorphic DNA PCR analysis and pulsed-field gel electrophoresis results indicated that the V. cholerae isolates belonged to the same clone. This investigation gives a warning that the El Tor variant of V. cholerae has spread to the coastal district causing a large outbreak that requires close monitoring and surveillance on diarrhoeal outbreaks in Odisha.

Outbreak of cholera caused by Vibrio cholerae O1 El Tor variant strain in Bihar, India.  

PubMed

An outbreak of cholera struck Bihar, an Indian state, in August 2008 following a massive flood. Here we report the phenotypic and genotypic characteristics of Vibrio cholerae strains isolated from patients with diarrhea. Rectal swabs were obtained from patients with diarrhea who were admitted to medical camps or the hospital, and the strains were biochemically and serologically characterized. V. cholerae was isolated from 21 (65.6%) of 32 rectal swabs. Serological studies revealed that all the 21 isolates belonged to V. cholerae O1 Ogawa. Mismatch amplification mutation assay (MAMA)-PCR showed that the isolates belonged to El Tor variant group, and pulsed-field gel electrophoresis (PFGE) proved that these isolates were of a different lineage than the conventional El Tor variant strains. These isolates were resistant to several drugs, including ampicillin, streptomycin, tetracycline, nalidixic acid, and furazolidone. The uniqueness of the current report arises from the fact that records of cholera in Bihar are availiable for the early 1960s but not for the next 4 decades. Moreover, the present study is the first to report a cholera outbreak in Bihar that was caused by an El Tor variant strain. PMID:24858614

Here we outline the methodology to obtain a redshift from the GRB afterglow spectrum using the recently installed Space Telescope Imaging Spectrograph (STIS) instrument onboard the Hubble Space Telescope. A low-resolution spectrum with the Multi-Anode Microchannel Array (MAMA) detector gives complete spectral coverage over the wavelength range 157.0-318.0 nm (Near UV) and 115.0-174.0 nm (Far UV). Assuming a Target of Opportunity observation is conducted soon (< 3 weeks) after a bright burst, a relatively small integration time (about 3 orbits) would be sufficient to detect the Lyman limit over a wide redshift range (0.3 < z < 2.2). Detection (or non-detection) of the Lyman limit, in concert with ground-based observations of nearby galaxies and Mg II and C IV absorption lines, should provide meaningful constraints on the relationship of GRBs to galaxies.

Population prevalence of hereditary breast cancer phenotypes and implementation of a genetic cancer risk assessment program in southern Brazil  

PubMed Central

In 2004, a population-based cohort (the Núcleo Mama Porto Alegre - NMPOA Cohort) was started in Porto Alegre, southern Brazil and within that cohort, a hereditary breast cancer study was initiated, aiming to determine the prevalence of hereditary breast cancer phenotypes and evaluate acceptance of a genetic cancer risk assessment (GCRA) program. Women from that cohort who reported a positive family history of cancer were referred to GCRA. Of the 9218 women enrolled, 1286 (13.9%) reported a family history of cancer. Of the 902 women who attended GCRA, 55 (8%) had an estimated lifetime risk of breast cancer ? 20% and 214 (23.7%) had pedigrees suggestive of a breast cancer predisposition syndrome; an unexpectedly high number of these fulfilled criteria for Li-Fraumeni-like syndrome (122 families, 66.7%). The overall prevalence of a hereditary breast cancer phenotype was 6.2% (95%CI: 5.67-6.65). These findings identified a problem of significant magnitude in the region and indicate that genetic cancer risk evaluation should be undertaken in a considerable proportion of the women from this community. The large proportion of women who attended GCRA (72.3%) indicates that the program was well-accepted by the community, regardless of the potential cultural, economic and social barriers.

Performance of the Space Telescope Imaging Spectrograph after SM4  

NASA Technical Reports Server (NTRS)

On May 17, 2009, during the fourth EVA of SM4, astronauts Michael Good and Mike Massimino replaced the failed LVPS-2 circuit board on the Space Telescope Imaging Spectrograph (STIS), restoring this HST instrument to operation after a nearly 6 year hiatus. STIS after this 2009 repair operates in much the same way as it did during the 2001-2004 period of operations with the Side-2 electronics. Internal and external alignments of the instrument are similar to what they had been in 2004, and most changes in performance are modest. The STIS CCD detector continued to experience radiation damage during the hiatus in operations, leading to decreased charge transfer efficiency (CTE) and an increased number of hot pixels. The sensitivities for most modes are surprisingly close to what was expected from simple extrapolation of the 2003-2004 trends, although the echelle modes show somewhat more complex behavior. The biggest surprise was that the dark count rate for the NUV MAMA detector after SM4 has been much larger than had been expected; it is currently about 2.5 times bigger than it was in 2004 and is only slowly decreasing. We discuss how these changes will affect science with STIS now and in the future.

Bridging the personal and the political: practices for a liberation psychology.  

PubMed

In the Irish context, legacies of colonialism, the Northern Ireland conflict situation, and the strength of community and women's liberation movements all provide rich resources for understanding the processes involved in both oppression and liberation. This paper draws on the theoretical and research literature and on Irish experiences to develop an understanding of some of the processes and practices that aid in liberation. The research is grounded in diverse writings on oppression and liberation, which include writings on colonialism (E. Duran & B. Duran, 1995; F. Fanon, 1967; V. Kenny, 1985, L. Maracle, 1996), feminist psychology (J. B. Miller, 1986; S. Wilkinson, 1996), liberation psychology (H. A. Bulhan, 1985; L. Comas-Díaz, M. B. Lykes, & R. D. Alarcon, 1998; I. Martín-Baró 1994; Starhawk, 1987), and psychological aspects of racism (b. hooks, 1993; A. Mama, 1995; R. J. Watts, D. M. Griffith, & J. Abdul-Adil, 1999), homophobia (A. R. D'Augelli & C. J. Patterson, 1995), poverty (K. O'Neill, 1992), and other dimensions of oppression. PMID:12741692

Digging Movie from Phoenix's Sol 18  

NASA Technical Reports Server (NTRS)

The Surface Stereo Imager on NASA's Phoenix Mars Lander recorded the images combined into this movie of the lander's Robotic Arm enlarging and combining the two trenches informally named 'Dodo' (left) and 'Goldilocks.'

The 21 images in this sequence were taken over a period of about 2 hours during Phoenix's Sol 18 (June 13, 2008), or the 18th Martian day since landing.

The main purpose of the Sol 18 dig was to dig deeper for learning the depth of a hard underlying layer. A bright layer, possibly ice, was increasingly exposed as the digging progressed. Further digging and scraping in the combined Dodo-Goldilocks trench was planned for subsequent sols.

The combined trench is about 20 centimeters (about 8 inches) wide. The depth at the end of the Sol 18 digging is 5 to 6 centimeters (about 2 inches).

The Goldilocks trench was the source of soil samples 'Baby Bear' and 'Mama Bear,' which were collected on earlier sols and delivered to instruments on the lander deck. The Dodo trench was originally dug for practice in collecting and depositing soil samples.

The Phoenix Mission is led by the University of Arizona, Tucson, on behalf of NASA. Project management of the mission is by NASA's Jet Propulsion Laboratory, Pasadena, Calif. Spacecraft development is by Lockheed Martin Space Systems, Denver.

Todos los exámenes de detección de cáncer que se usan extensamente tienen el objetivo de detectar el cáncer a tiempo, cuando el tratamiento puede tener más éxito. Pero varias pruebas de detección pueden también ayudar a encontrar células anormales que no se han convertido todavía en cancerosas, lo que permite que se extirpen antes de que causen problemas. Las pruebas de detección de cáncer colorrectal, es decir, en el colon y recto, pueden ayudar a detectar formaciones precancerosas que se llaman pólipos.

Kinks of the Transplant Renal Artery Without Accompanying Intraarterial Pressure Gradient Do Not Require Correction: Five-Year Outcome Study  

SciTech Connect

Significant transplant renal artery stenosis (TRAS) results in an intraarterial pressure gradient and increasing graft dysfunction correctable by endovascular therapy. Kinks of the transplant artery cause velocity gradients on Doppler ultrasound, but some will have no intraarterial pressure gradient across the kink. It is not known whether these nonflow limiting kinks progress further to threaten graft function and should undergo endovascular correction. This is a longitudinal study of conservatively managed arterial kinks to define their natural history. Fourteen patients who had undergone angiography over a 5-year period for suspected TRAS had kinks of the renal artery. True intraarterial pressures were measured in all cases by slow withdrawal of an end-hole catheter after intraarterial injection of a vasodilator. Those with a significant pressure change ({>=}10% change in peak systolic pressure across the area of suspicion) underwent endovascular treatment. The rest were managed conservatively, with maximal antihypertensive therapy. Outcome of all 14 cases was determined by follow-up of creatinine levels, blood pressure (BP) control and graft outcome over a 3-5-year period (median 4 years). Of the 14 patients with kinks, 10 were male and 4 female; age range 23-67 years (mean 47 years). Eleven had received cadaveric transplants and 3 were allografts; 12 had end-to-side and 2 end-to-end anastomosis, 11/14 cases had an intraarterial pressure ratio of <10% and at median 4 years follow-up on conservative treatment, the serum creatinine of these 11 patients did not differ significantly from those who underwent successful endovascular treatment (mean 118 {mu}mol/l versus 149 {mu}mol/l; p = 0.30, Mann Whitney test). Mean blood pressure was 137/82 mmHg, with a range of 124-155/56-95 mmHg. Only one patient has required an unexplainable increase in antihypertensive medication. Grafts (2/11) were lost and both had chronic rejection on histology. There were no unexplained graft failures. Kinks of the renal transplant artery with normal intraarterial pressures do not appear to progress and threaten renal graft function. Satisfactory graft outcome was seen on 5-year follow-up with conservative therapy alone.

Detrimental impact of remote methamphetamine dependence on neurocognitive and everyday functioning in older but not younger HIV+ adults: evidence for a legacy effect?  

PubMed

Prior studies examining the combined adverse effects of HIV and methamphetamine (MA) on the central nervous system (CNS) have focused on younger to middle-aged adults with recent MA use diagnoses. Aging, HIV, and MA all converge on prefrontal and temporolimbic neural systems and confer independent risk for neurocognitive and functional decline. Thus, this study sought to determine the residual impact of a remote history of MA dependence on neurocognitive and real-world outcomes in older people living with HIV (PLWH). Participants included 116 older (?50 years) and 94 younger (<40 years) adults classified into one of six study groups based on HIV serostatus (HIV+/HIV-) and lifetime histories of MA dependence (MA+/MA-): older HIV-MA- (n?=?36), older HIV+MA- (n?=?49), older HIV+MA+ (n?=?31), younger HIV-MA- (n?=?27), younger HIV+MA- (n?=?33), and younger HIV+MA+ (n?=?34). No participant-met criteria for current MA use disorders and histories of MA dependence were remote in both the older (average of nearly 9 years prior to evaluation) and younger (average of over 2 years prior to evaluation) HIV+MA+ groups. Findings revealed that a remote history of MA dependence exerts a significant detrimental impact on specific aspects of neurocognitive performance (e.g., memory) and a broad range of real-world functioning outcomes (e.g., employment) among older, but not younger PLWH. These results suggest that MA-associated neurotoxicity may have significant "legacy" effects on both neurocognitive and functional outcomes to which older PLWH are particularly vulnerable.

Auditory spatial resolution in horizontal, vertical, and diagonal planes.  

PubMed

Minimum audible angle (MAA) and minimum audible movement angle (MAMA) thresholds were measured for stimuli in horizontal, vertical, and diagonal (60 degrees) planes. A pseudovirtual technique was employed in which signals were recorded through KEMAR's ears and played back to subjects through insert earphones. Thresholds were obtained for wideband, high-pass, and low-pass noises. Only 6 of 20 subjects obtained wideband vertical-plane MAAs less than 10 degrees, and only these 6 subjects were retained for the complete study. For all three filter conditions thresholds were lowest in the horizontal plane, slightly (but significantly) higher in the diagonal plane, and highest for the vertical plane. These results were similar in magnitude and pattern to those reported by Perrott and Saberi [J. Acoust. Soc. Am. 87, 1728-1731 (1990)] and Saberi and Perrott [J. Acoust. Soc. Am. 88, 2639-2644 (1990)], except that these investigators generally found that thresholds for diagonal planes were as good as those for the horizontal plane. The present results are consistent with the hypothesis that diagonal-plane performance is based on independent contributions from a horizontal-plane system (sensitive to interaural differences) and a vertical-plane system (sensitive to pinna-based spectral changes). Measurements of the stimuli recorded through KEMAR indicated that sources presented from diagonal planes can produce larger interaural level differences (ILDs) in certain frequency regions than would be expected based on the horizontal projection of the trajectory. Such frequency-specific ILD cues may underlie the very good performance reported in previous studies for diagonal spatial resolution. Subjects in the present study could apparently not take advantage of these cues in the diagonal-plane condition, possibly because they did not externalize the images to their appropriate positions in space or possibly because of the absence of a patterned visual field.

Background and Scattered Light Subtraction in the High-Resolution Echelle Modes of the Space Telescope Imaging Spectrograph  

E-print Network

We present a simple, effective approach for estimating the on-order backgrounds of spectra taken with the highest-resolution modes of the Space Telescope Imaging Spectrograph (STIS) on-board the Hubble Space Telescope. Our scheme for determining the on-order background spectrum uses polynomial fits to the inter-order scattered light visible in the two-dimensional STIS MAMA images. We present a suite of high-resolution STIS spectra to demonstrate that our background subtraction routine produces the correct overall zero point, as judged by the small residual flux levels in the centers of strongly-saturated interstellar absorption lines. Although there are multiple sources of background light in STIS echelle mode data, this simple approach works very well for wavelengths longward of Lyman-alpha. At shorter wavelengths, the smaller order separation and generally lower signal-to-noise ratios of the data can reduce the effectiveness of our background estimation procedure. Slight artifacts in the background-subtracted spectrum can be seen in some cases, particularly at wavelengths <1300 Ang. Most of these are caused by echelle scattering of strong spectral features into the inter-order light. We discuss the limitations of high-resolution STIS data in light of the uncertainties associated with our background subtraction procedure. We compare our background-subtracted STIS spectra with GHRS Ech-A observations of the DA white dwarf G191-B2B and GHRS first-order G160M observations of the early-type star HD 218915. We find no significant differences between the GHRS data and the STIS data reduced with our method in either case.

A High-Throughput Data Mining of Single Nucleotide Polymorphisms in Coffea Species Expressed Sequence Tags Suggests Differential Homeologous Gene Expression in the Allotetraploid Coffea arabica1[W  

PubMed Central

Polyploidization constitutes a common mode of evolution in flowering plants. This event provides the raw material for the divergence of function in homeologous genes, leading to phenotypic novelty that can contribute to the success of polyploids in nature or their selection for use in agriculture. Mounting evidence underlined the existence of homeologous expression biases in polyploid genomes; however, strategies to analyze such transcriptome regulation remained scarce. Important factors regarding homeologous expression biases remain to be explored, such as whether this phenomenon influences specific genes, how paralogs are affected by genome doubling, and what is the importance of the variability of homeologous expression bias to genotype differences. This study reports the expressed sequence tag assembly of the allopolyploid Coffea arabica and one of its direct ancestors, Coffea canephora. The assembly was used for the discovery of single nucleotide polymorphisms through the identification of high-quality discrepancies in overlapped expressed sequence tags and for gene expression information indirectly estimated by the transcript redundancy. Sequence diversity profiles were evaluated within C. arabica (Ca) and C. canephora (Cc) and used to deduce the transcript contribution of the Coffea eugenioides (Ce) ancestor. The assignment of the C. arabica haplotypes to the C. canephora (CaCc) or C. eugenioides (CaCe) ancestral genomes allowed us to analyze gene expression contributions of each subgenome in C. arabica. In silico data were validated by the quantitative polymerase chain reaction and allele-specific combination TaqMAMA-based method. The presence of differential expression of C. arabica homeologous genes and its implications in coffee gene expression, ontology, and physiology are discussed. PMID:20864545

Drug response and genetic properties of Vibrio cholerae associated with endemic cholera in north-eastern Thailand, 2003-2011  

PubMed Central

Cholera, caused by Vibrio cholerae, results in significant morbidity and mortality worldwide, including Thailand. Representative V. cholerae strains associated with endemic cholera (n?=?32), including strains (n?=?3) from surface water sources, in Khon Kaen, Thailand (2003–2011), were subjected to microbiological, molecular and phylogenetic analyses. According to phenotypic and related genetic data, all tested V. cholerae strains belonged to serogroup O1, biotype El Tor (ET), Inaba (IN) or Ogawa (OG). All of the strains were sensitive to gentamicin and ciprofloxacin, while multidrug-resistant (MDR) strains showing resistance to erythromycin, tetracycline, trimethoprim/sulfamethoxazole and ampicillin were predominant in 2007. V. cholerae strains isolated before and after 2007 were non-MDR. All except six diarrhoeal strains possessed ctxA and ctxB genes and were toxigenic altered ET, confirmed by MAMA-PCR and DNA sequencing. Year-wise data revealed that V. cholerae INET strains isolated between 2003 and 2004, plus one strain isolated in 2007, lacked the RS1 sequence (rstC) and toxin-linked cryptic plasmid (TLC)-specific genetic marker, but possessed CTXCL prophage genes ctxBCL and rstRCL. A sharp genetic transition was noted, namely the majority of V. cholerae strains in 2007 and all in 2010 and 2011 were not repressor genotype rstRCL but instead were rstRET, and all ctx+ strains possessed RS1 and TLC-specific genetic markers. DNA sequencing data revealed that strains isolated since 2007 had a mutation in the tcpA gene at amino acid position 64 (N?S). Four clonal types, mostly of environmental origin, including subtypes, reflected genetic diversity, while distinct signatures were observed for clonally related, altered ET from Thailand, Vietnam and Bangladesh, confirmed by distinct subclustering patterns observed in the PFGE (NotI)-based dendrogram, suggesting that endemic cholera is caused by V. cholerae indigenous to Khon Kaen.

Photopyroelectric Calorimetry of {Fe}3{O}4 Magnetic Nanofluids: Effect of Type of Surfactant and Magnetic Field  

NASA Astrophysics Data System (ADS)

Five types of magnetic nanofluids, based on {Fe}3{O}4 nanoparticles with water as the carrier liquid, were investigated by using the two photopyroelectric (PPE) detection configurations (back (BPPE) and front (FPPE)), together with the thermal-wave resonator cavity (TWRC) technique as the scanning procedure. The difference between the nanofluids was the type of surfactant: double layers of lauric (LA-LA), oleic (OA-OA), and miristic (MA-MA) acids and also double layers of lauric-miristic (LA-MA) and palmitic-oleic (PA-OA) fatty acids were used. In both detection configurations, the information was contained in the phase of the PPE signal. The thermal diffusivity of nanofluids was obtained in the BPPE configuration, from the scan of the phase of the signal as a function of the liquid's thickness. Using the same scanning procedure in the FPPE configuration, the thermal effusivity was directly measured. The influence of a 0.12 kG magnetic field on the thermal effusivity and thermal diffusivity was also investigated. Because of different surfactants, the thermal effusivity of the investigated nanofluids ranges from 1530 {W}\\cdot {s}^{1/2} \\cdot { m}^{-2}\\cdot { K}^{-1} to 1790 { W}\\cdot {s}^{1/2}\\cdot { m}^{-2}\\cdot { K}^{-1}, and the thermal diffusivity, from 14.54 × 10^{-8} { m}2\\cdot { s}^{-1} to 14.79 × 10^{-8} { m}2\\cdot { s}^{-1}. The magnetic field has practically no influence on the thermal effusivity, and produces a maximum increase of the thermal diffusivity (LA-LA surfactant) of about 4 %.

The D/H Abundance Ratio in Local Interstellar Gas  

NASA Astrophysics Data System (ADS)

Does the D/H ratio vary within ~ 100 pc of the Sun? If it does, what is the range of these variations? Are the D/H variations correlated to any physical property of the absorbing cloud? To answer these questions we have begun a project to obtain high-precision D/H abundance ratios in the Local Interstellar Medium within ~ 100 pc (Sahu et al. 1999, ApJ 523, L159). For this purpose, we primarily use HST-Space Telescope Imaging Spectrograph (STIS) data towards nearby hot, white dwarfs (WDs). The advantages of using STIS for this study are: (1) The high velocity resolution of STIS in the UV ( ~ 2 km s-1 in the E140H and E230H modes) allows the velocity structure in the sightline to be resolved and reliable component-to-component variations can be studied (2) WDs provide a strong, smooth UV continuum against which other diagnostic interstellar absorption lines can be measured. The wider wavelength coverage ( ~ 200 Angstroms per setting) of STIS in the high-resolution E140H mode allows important interstellar lines such as N i, Si ii, O i and S ii to be measured in addition to D i and H i, at no extra cost in HST time (3) The superior echelle scatter and background corrections possible with the 2-dimensional STIS-MAMA detectors allow more accurate D/H determinations from WD spectra. In this poster, we present a status report of our project along with some recent results.

An infant with mos45,X/46,XY/47,XYY/48,XYYY: Genetic and clinical findings  

SciTech Connect

We report on an infant with mos45,X/46,XY/47,XYY/48,XYYY who presented with ambiguous genitalia. The patient was the 2,637 gram product of a 38 week gestation and elective repeat C-section born to a 35 year old G3P2 mother. The pregnancy was complicated by placenta previa. There was no history of maternal health problems or drug or steroid use. At birth bilateral epicanthal folds and overfolded helices were noted without webbing of the neck or lymphedema. There was a phallic structure measuring 1.5 cm with dorsal hood and midline cleft with a normal female introitus, urethra, and vagina. Congenital adrenal hyperplaxia was excluded. Renal ultrasound was normal. Periperal blood chromosomes revealed a mos45,X(38%)/47,XYY(29%)/48,XYYY(33%) karyotype. Echocardiography revealed coarctation of the aorta and a bicuspid aortic valve. An additional cell line, 46,XY, was identified in aortic tissue obtained at the time of surgery. At age 15 months she was 25% in height and weight and had bilateral ptosis. Her development was within normal limits, but no words except {open_quotes}Mama{close_quotes} or {open_quotes}Dada{close_quotes} were spoken. A left intraabdominal testis with epididymis and dilated tubules and bilateral Fallopian tubes were removed at laparoscopy/reconstruction. Cell cultures were initiated from gonadal tissue, and karyotypes are pending. Patients with mosaic Y chromosome aneuploidy involving 2 Y chromosomes are rare. Eighteen patients with 45,X/47,XYY have been described; prenatally diagnosed cases appeared to be normal male whereas cases diagnosed postnally presented with ambiguous genitalia and/or other anomalies. The phenotype of Y chromosome aneuploidy with 3 Y chromosomes is even more unpredictable due to the paucity of reported cases. To our knowledge this is the first patient described with this unusual karyotype, thus adding to the limited information of patients with rare mosaic Y chromosome aneuploidy.

Extensive SAR studies of taxanes in these laboratories led to the discovery of new generation taxanes that are highly active against not only drug-sensitive but also drug-resistant human cancer cell lines as well as tumor xenografts in mice. One of these second generation taxanes, SB-T-110131 (IDN5109), exhibited excellent pharmacological profile in the preclinical studies and has been selected for clinical development (recoded as Bay 59-8862), which is currently in the phase II clinical trials. Bay 59-8862 is orally active with high bioavailability, showing excellent activity against a variety of drug-resistant tumors. "Advanced second generation taxanes" show essentially no difference in cytotoxicity against drug-resistant and drug-sensitive cell lines, virtually overcoming MDR. Photoaffinity labeling of P-GP using photoreactive radiolabeled paclitaxel analogs has disclosed the paclitaxel-binding domain of P-GP. Highly efficient taxane-based MDR reversal agents (TRAs) have also been developed, which can recover the cytotoxicity of paclitaxel to practically the original level against paclitaxel-resistant MDR expressing cancer cells. Highly promising results have emerged from the study of taxane-monoclonal antibody (MAb) immunoconjugates, which have been proved to specifically deliver extremely cytotoxic agents to tumor in an animal model.

Overcoming multidrug resistance in taxane chemotherapy.  

PubMed

Paclitaxel (Taxol) and docetaxel (Taxotère) are currently two of the most important anticancer drugs in cancer chemotherapy. However, clinical treatment with these taxane agents often encounters undesirable side effects and multidrug resistance (MDR) caused by overexpression of P-glycoprotein (Pgp). Photoaffinity labeling of Pgp using photoreactive radiolabeled paclitaxel analogs along with molecular modeling has revealed a unique binding region for paclitaxel on the C-terminal half of Pgp. Highly efficient taxane-based MDR reversal agents (TRAs) have been developed. Extensive structure-activity relationship (SAR) studies have led to the development of new generation taxanes that possess 2-3 orders of magnitude higher potencies against human cancer cell lines expressing the MDR phenotype. One of these taxanes, SB-T-1 10131 (IDN5109, BAY59-8862), exhibits excellent activity against a variety of drug-sensitive and drug-resistant cancer cell lines as well as human tumor xenografts in mice. This taxane is orally active with excellent bioavailability, and is currently undergoing phase II human clinical trials. Novel taxane-antibody immunoconjugates have shown very promising results for tumor-specific delivery and release of an extremely cytotoxic taxane, wherein epidermal growth factor receptor is used as the specific antigen on the tumor surface of human squamous cancer xenograft in SCID mice.

Epithelial cytoprotection sustains ectopic expression of tissue-restricted antigens in the thymus during murine acute GVHD.  

PubMed

Development of acute graft-versus-host disease (aGVHD) predisposes to chronic GVHD with autoimmune manifestations. A characteristic of experimental aGVHD is the de novo generation of autoreactive T cells. Central tolerance is dependent on the intrathymic expression of tissue-restricted peripheral self-antigens (TRA), which is in mature medullary thymic epithelial cells (mTEC(high)) partly controlled by the autoimmune regulator (Aire). Because TECs are targets of donor T-cell alloimmunity, we tested whether murine aGVHD interfered with the capacity of recipient Aire(+)mTEC(high) to sustain TRA diversity. We report that aGVHD weakens the platform for central tolerance induction because individual TRAs are purged from the total repertoire secondary to a decline in the Aire(+)mTEC(high) cell pool. Peritransplant administration of an epithelial cytoprotective agent, fibroblast growth factor-7, maintained a stable pool of Aire(+)mTEC(high), with an improved TRA transcriptome despite aGVHD. Taken together, our data provide a mechanism for how autoimmunity may develop in the context of antecedent alloimmunity. PMID:23719300

Test Observations and Plans For the Hubble Deep Field - South  

NASA Astrophysics Data System (ADS)

We will discuss the planning process, scheduling constraints, and scientific considerations which we have studied and undertaken thus far for the southern Hubble Deep Field observations which are to be performed in October of 1998. Observations from a 3-orbit test program taken in October 1997 at the same position angle and with the same guide stars will be presented to the community for comment and for informational purposes. Planning is constrained in part by CVZ passages, by solar avoidance, zodiacal light, effective use of filters and gratings minimizing effects of scattered earthshine, SAA avoidance, avoidance of bright stars, and availability of suitable guide stars. In particular, it is crucial to test the same guide stars that will be used for the full set of observations. This preview of science data on the field will also allow us to fine-tune any other aspects of the program which may be better optimized scientifically. The HDF-S test observations will consist of one orbit of STIS 50CCD clear aperture imaging to image the field around the QSO, and two orbits of STIS NUV-MAMA G230L spectroscopy on the QSO to obtain a low resolution spectrum. In addition, three orbits of WFPC2 F606W imaging will be obtained in parallel on a field about 6.2 arc minutes from the QSO, and three orbits of NIC3 F160W imaging will be obtained in parallel on a field about 8.7 arc minutes from the QSO. The actual HDF-S observations next October are currently planned to include the same complement of filters for WFPC2 as was used in the original HDF-N ( F300W, F450W, F606W, and F814W ). Other options yet to be determined will be pursued for STIS and NICMOS for the full campaign.

Trends in antenatal care attendance and health facility delivery following community and health facility systems strengthening interventions in Northern Uganda  

PubMed Central

Background Maternal morbidity and mortality remains high in Uganda; largely due to inadequate antenatal care (ANC), low skilled deliveries and poor quality of other maternal health services. In order to address both the demand and quality of ANC and skilled deliveries, we introduced community mobilization and health facility capacity strengthening interventions. Methods Interventions were introduced between January 2010 and September 2011. These included: training health workers, provision of medical supplies, community mobilization using village health teams, music dance and drama groups and male partner access clubs. These activities were implemented at Kitgum Matidi health center III and its catchment area. Routinely collected health facility data on selected outcomes in the year preceding the interventions and after 21 months of implementation of the interventions was reviewed. Trend analysis was performed using excel and statistical significance testing was performed using EPINFO StatCal option. Results The number of pregnant women attending the first ANC visit significantly increased from 114 to 150 in the first and fourth quarter of 2010 (OR 1.72; 95% CI 1.39–2.12) and to 202 in the third quarter of 2011(OR 11.41; 95% CI 7.97–16.34). The number of pregnant women counselled, tested and given results for HIV during the first ANC attendance significantly rose from 92 (80.7%) to 146 (97.3%) in the first and fourth quarter of 2010 and then to 201 (99.5%) in the third quarter of 2011. The number of male partners counseled, tested and given results together with their wives at first ANC visit rose from 13 (16.7%) in the fourth quarter of 2009 to 130 (89%) in the fourth quarter of 2010 and to 180 (89.6%) in the third quarter of 2011. There was a significant rise in the number of pregnant women delivering in the health facility with provision of mama-kits (delivery kits), from 74 (55.2%) to 149 (99.3%) in the second and fourth quarter of 2010. Conclusions Combined community and facility systems strengthening interventions led to increased first ANC visits by women and their partners, and health facility deliveries. Interventions aimed at increasing uptake of maternal health services should address both the demand and availability of quality services. PMID:24134717

Polystyrene grafting from silica nanoparticles via Nitroxide-Mediated-Polymerization (NMP): synthesis and SANS analysis with contrast variation method  

E-print Network

We present a new convenient and efficient "grafting from" method to obtain well defined polystyrene (PS) silica nanoparticles. The method, based on Nitroxide-Mediated Polymerization (NMP), consists to bind covalently the alkoxyamine, which acts as initiator controller agent, at the silica nanoparticles surface in two steps. The first step is a reaction between the aminopropylsilane and the silica particles in order to functionalize the particles surface with amino group. In a second step, the initiating-controlling alkoxyamine moiety is introduced via an over grafting reaction between the amino group and the N-hydroxysuccinimide based MAMA-SG1 activated ester. To simplify both their chemical transformation and the polymerization step, the native silica particles, initially dispersed in water, have been transferred in an organic solvent, the dimethylacetamide, which is also a good solvent for the polystyrene. The synthesis parameters have been optimized for grafting density, conversion rates, and synthesis reproducibility while keeping the colloidal stability and to avoid any aggregation of silica particles induced by the inter-particles interaction evolution during the synthesis. After synthesis, the final grafted objects have been purified and the non-grafted polymer chains formed in the solvent have been washed out by ultra filtration. Then the particles have been studied using Small angle Neutron Scattering (SANS) coupled to neutron contrast variation method. To optimize the contrast conditions, both hydrogenated and deuterated monomers have been used for the synthesis. A refined fitting analysis based on the comparison on two models, a basic core-shell and the Gaussian Pedersen model, enables us to fit nicely the experimental data for both the hydrogenated and deuterated grafted case. Differences are seen between grafting of normal or deuterated chains which can be due to monomer reactivity or to neutron contrast effect variations. The synthesis and the characterization method established in this work constitute a robust and reproducible way to design well defined grafted polymer nanoparticles. These objects will be incorporated in polymer matrices in a further step to create Nanocomposites for polymer reinforcement.

Dust and Diffuse Interstellar Bands in the z_a = 0.524 Absorption System toward AO 0235+164  

E-print Network

We present new HST STIS NUV-MAMA and STIS CCD observations of the BL Lac object AO 0235+164 and the intervening damped Ly alpha (DLA) line at z_a = 0.524. The line profile gives N(H I) = 5 +/- 1 x 10^{21} cm^{-2} and, combined with the H I 21 cm absorption data leads to a spin temperature of T_s = 220 K +/- 60 K. Those spectra also show a strong, broad feature at the expected position of the 2175 Angstrom graphitic dust feature at z_a = 0.524. Assuming a Galactic type dust extinction curve at z_a = 0.524 gives a dust-to-gas ratio of 0.19 Galactic, but the fit, assuming the underlying, un-reddened spectrum is a single power-law, is poor in the far-UV. A dust-to-gas ratio of 0.19 Galactic is similar to the LMC, but the AO 0235+164 spectrum does not fit the LMC extinction curve, or the SMC extinction curve (which has practically no 2175 Angstrom feature). A possible interpretation includes dust similar to Galactic, but with less of the small particles that produce the far-UV extinction. The metallicity of the z_a = 0.524 absorber, estimated from the observed N(H I) and excess X-ray absorption (beyond Galactic) derived from contemporaneous and archival ASCA and ROSAT X-ray data, is Z = 0.72 +/- 0.28 Z_sun, implying in turn the dust-to-metals ratio of 0.27 Galactic. If the dust mass density is the same in the z_a = 0.524 DLA system as in our Galaxy, only 14% (+/- 6%) of the metals (by mass) are in dust compared with 51%, 36%, and 46% for the Galaxy, LMC, and SMC respectively. Such a dusty z_a = 0.524 AO 0235+164 absorption system is a good example of the kind of DLA system that will be missed due to selection effects, which in turn can bias the measurement of the co-moving density of interstellar gas (in units of the closure density), Omega_g, as a function of z.

PubMed Central

Introduccion La diabetes mellitus y las demencias constituyen dos problemas crecientes de salud entre la población adulta mayor del mundo y en particular de los paises en desarrollo. Hacen falta estudios longitudinales sobre el papel de la diabetes como factor de riesgo para demencia. Objetivo Determinar el riesgo de demencia en sujetos Mexicanos con diabetes mellitus tipo 2. Materiales y Metodos Los sujetos diabéticos libres de demencia pertenecientes al Estudio Nacional de Salud y Envejecimiento en México fueron evaluados a los dos años de la línea de base. Se estudió el papel de los factores sociodemográficos, de otras comorbilidades y del tipo de tratamiento en la conversión a demencia. Resultados Durante la línea de base 749 sujetos (13.8%) tuvieron diabetes. El riesgo de desarrollar demencia en estos individuos fue el doble (RR, 2.08 IC 95%, 1.59–2.73). Se encontró un riesgo mayor en individuos de 80 años y más (RR 2.44 IC 95%, 1.46–4.08), en los hombres (RR, 2.25 IC 95%, 1.46–3.49) y en sujetos con nivel educativo menor de 7 años. El estar bajo tratamiento con insulina incrementó el riesgo de demencia (RR, 2.83, IC 95%, 1.58–5.06). Las otras comorbilidades que aumentaron el riesgo de demencia en los pacientes diabéticos fueron la hipertensión (RR, 2.75, IC 95%, 1.86–4.06) y la depresión (RR, 3.78, 95% IC 2.37–6.04). Conclusión Los sujetos con diabetes mellitus tienen un riesgo mayor de desarrollar demencia, La baja escolaridad y otras comorbilidades altamente prevalentes en la población Mexicana contribuyen a la asociación diabetes-demencia.

Grupos españoles de cálculos ab initio de moléculas de interés astrofísico  

NASA Astrophysics Data System (ADS)

Pocos campos de la química están tan bien adaptados a la modelización por medio de los métodos teóricos de la Química Cuántica como la Astroquímica y la Química de la Atmósfera, donde las interacciones moleculares son, generalmente, lo suficientemente pequeñas para que el modelo de molécula aislada funcione muy bien. En España son varios los grupos teóricos que dedican su esfuerzo de investigación, o parte de él, al estudio de moléculas o procesos de interés en Astrofísica o en atmósferas planetarias. Presentaremos diferentes ejemplos paradigmáticos de esta actividad en la que se exploran desde aspectos estructurales, hasta aspectos espectroscópicos y dinámicos. Entre los últimos, cabe destacar estudios en los que se demuestra la importancia de procesos a dos estados, prohibidos por espín, en la formación astrofísica de diversos derivados de interés. En el tratamiento espectroscópico se han hecho esfuerzos interesantes, que han aunado teoría y experimento, en el estudio de sistemas relevantes desde el punto de vista atmosférico, como los hidratos de ácido nítrico, o el tratamiento espectroscópico de moléculas no rígidas. No menos interesantes son los estudios de fotoabsorción de radicales o de procesos multifotónicos. Son particularmente abundantes los estudios dedicados a la reactividad específica de sistemas de interés astrofísico o atmosférico, con el objetivo de esclarecer vías de formación de determinados compuestos o de proporcionar mecanismos que permitan identificar las etapas reactivas limitantes de reacciones de interés en esos medios y sobre los que no existía información previa. Así, por ejemplo, se han publicado interesantes estudios sobre la formación o propiedades de compuestos de fósforo, de silico o de azufre o sobre mecanismos de reacción en los que intervienen el ozono, el radical nitrato, el radical OH u otras especies. Finalmente, son también particularmente relevantes los estudios que varios grupos españoles han llevado, y siguen llevando a cabo, sobre sistemas débilmente enlazados, como complejos de Van der Waals o complejos por enlace de hidrógeno, que sin duda juegan un papel importante tanto en medios atmosféricos como interestelares.

Imaging the Lithospheric - Asthenosphere Boundary Structure of the Westernmost Mediterranean Using S Receiver Functions  

NASA Astrophysics Data System (ADS)

The Iberian microcontinent, in the westernmost portion of the Mediterranean is comprised of the Betic Cordillera Zone, the South Portuguese Zone, the Ossa-Morena Zone, the Central Iberian Zone, the Galicia-Tras Os Montes Zone, the West Asturian-Leonese Zone, and the Cantabrian Zone. These zones were created as a result of three primary stages of Iberian evolution, with the last being the collision of Iberia with in the Late Cretaceous. In northeastern Africa, Neogene convergence between the European and African plates created the Alboran System: comprised of the Gibraltar Arc, Rif-Betics, Atlas Mountains, and Alboran Sea. The primary purpose of this study is to advance our understanding of the structure and evolution of the lithosphere, as well as the lithosphere - asthenosphere boundary (LAB) of the Iberian microcontinent and surrounding areas. Of particular interest is improving our understanding of the evolution from ocean subduction to continental collision that has been taking place in the late stage convergence of this part of the Mediterranean., The region is a particularly complex three-dimensional settings and, several models have been suggested to explain the tectonics of this system including: continental lithospheric delamination and drips, slab breakoff, and subducting slab rollback. Here we use broadband seismic data from 272 broadband instruments deployed in Morocco and Spain as part of the PICASSO and IBERArray (Díaz, J., et al., 2009) projects to constrain lithospheric structure via identification of S-to-p conversions from S receiver functions (SRF). We use SRFs to image the characteristics and structure in terms of seismic velocity discontinuities, including the crust-mantle boundary (Moho) and the lithosphere-asthenosphere boundary (LAB) beneath the region. Our SRFs agree with previous work that suggests that the lithospheric thickness is shallow (~65 km) beneath the Atlas and thickest (~120 km) beneath the Rif. Additionally, LAB structures correlate with the surface expression of tectonic features such as the South Pyrenean frontal thrust as well as the boundary between the Central System and the Madrid (Tagus) Basin.

[What's new in dermatological research?].  

PubMed

Medical literature is rich with new and relevant information, resulting from basic or applied research. Some strong arguments are presented in this document. Firstly, the discovery and role of a virus, the polyomavirus, in the development of Merkel tumours. It is a small virus with double bit DNA strand, coding for a oncoprotein. If the polyomavirus plays a causal role in the tumorigenesis, it acts by various mechanisms. The micro-RNAs represent an abundant class of small RNA not coding for proteins, but which control the gene expression coding for proteins on a post-transcriptional level. The first obvious sign of the role of the micro-RNAs in the inflammatory dermatoses appeared recently, in particular when these micro-RNAs associated with psoriasis and atopic dermatitis were identified through a broad genomic analysis of the expression of these micro-RNAs. A new giant virus strain sheltering another unknown tiny virus to date has just been discovered. This virus infinitely small called Sputnik enables to deteriorate a much larger virus baptized Mama, at the point of preventing it to manufacture normal viral particles and also preventing it from reproducing. This discovery raises a crucial question: Is Sputnik a new system of transfer of genes of a species of one virus to another? A group of blood cells expressing E-cadherin, the dot cells, found in the fetal blood of the dermis, contributes to tissue repair through the mechanisms of cellular differentiation and their action allows healing without scar. CD4+ T helper lymphocytes producing interleukin 17 (IL17) play a pathogenic part in atopic dermatitis. The genes of the beta defensins could be involved in the genetic susceptibility of the psoriatic disease. The autoimmune origin of the alopecia areata is supported by a great number of observations, the role of neuropeptides in the initiation of the autoimmunity during alopecia areata has just been demonstrated. The dendritic cells are cells presenting antigens which play a crucial role in the adaptive immunological response. It was shown that activation of the proliferation of the lymphocytes T after the migration of dendritic cells on the level of the lymphatic ganglion depended not on Langerhans cell, but of the dendritic cell. A new way appears to control the autoimmunity in the psoriasis and involves the plasmacytoid dendritic cells which are sensitized with the DNA itself when it is coupled with an antibacterial peptide. Mast cells express cathelicidin, which acts like an antibiotic with broad spectrum and influences the defence system of the epitheliums. We have perhaps found a new therapeutic target for rosacea by disclosing high rates of cathelicidin and a series of associated proteases in skin lesions. The sebocytes express antibacterial functional peptides deriving from cathelicidin which can have a bactericidal effect against P. Acnes. A vast genomic study in the androgenetic alopecia highlighted the existence of new loci localized on the 20p11 chromosome, associated with the risk of androgenetic alopecia. New alleles to determine the color of hair and the cutaneous pigmentation were identified. Two loci (IRF 4 and SLC24A4) are highly associated with the color of hair, like three other areas. The blue color of the eyes could be due to a change of an element located in gene HERC2 preventing of the expression of OCA2. Thus, many fields of dermatology were the object of research which opens new prospects for diagnosis and treatment. PMID:19264208

Early epoch stellar positions from the Bordeaux Carte du Ciel  

NASA Astrophysics Data System (ADS)

Astrometric measurements made by the satellite Hipparcos have brought forth a homogeneous system of precise proper motions of about 105 stars, which is unprecedented in its combination of quality and quantity. Such proper motions are of great importance in various sorts of kinematic studies. However, the proper motion system needs to be disseminated and extended to stars of fainter magnitudes by means of earth-bound observations. Here, photographic records of star positions from the beginning of the 20th century present a valuable and indispensable source of information. A first important step was made with the construction of the ACT Catalogue (Urban et al. 1997), which incorporates the ancient plate measurements of the so-called Astrographic Catalogue (AC). A second series of plates, the so-called Carte du Ciel (CdC), taken as part of the same survey project as the AC, has not been used systematically for astrometry so far. The advantage of the CdC is that it reaches about 3 mag fainter than the AC. It provides however less redundancy from plate overlap. The Observatoire de Bordeaux has initiated a program for the digitisation and measurement of its collection of CdC plates which covers the zone of +11 to +17 declination and contains positions for about 8 × 105 stars at epochs mostly between 1910 and 1920. As a pilot study for this program, we are currently working on two regions near the galactic anticenter, one surrounding the open cluster NGC 2355, the other intersecting the galactic plane at l 195. These regions were selected for practical as well as for scientific reasons. The plates have been digitised on the MAMA machine at the Observatoire de Paris. Object detection was made using the software SExtractor (Bertin & Arnouts 1996). The plate limit proves to be at B = 15 and a completeness of 80 percent is reached up to 14th magnitude. The plates of the CdC provide three equal exposures with a small angular separation of 10 arc second. A loss of about 20 percent of stars must be accepted due to interferences between the grid lines and the triple exposures. Refined object positions are derived by fitting a 2-D triple gaussian to the images (cf. Dick et al. 1993). A direct reduction of the measurements to the Hipparcos catalogue is not advisable because of the density of Hipparcos stars being low and because of problems from overexposure. Instead, the use of the ACT as a reference catalogue is appropriate. Rms residuals in the reduction to ACT are typically around 0.15 arc second. Comparing the positions of stars in the overlapping borders of adjacent plates, we obtain consistency on the level of 0.2 arc second for non-corner regions and 0.3 arc second for corner regions. This indicates typical positional accuracies of 0.15 arc second and 0.2 arc second respectively per star and plate. Proper motions are determined in combination with recent observations obtained with the Bordeaux meridian circle (see Colin, this volume, p. 141). With an epoch difference of 80 years, a proper motion accuracy of typically 2.5 mas/y is achieved.

The residual and direct effects of reduced-risk and conventional miticides on twospotted spider mites, Tetranychus urticae (Acari: Tetranychidae) and predatory mites (Acari: Phytoseiidae)  

SciTech Connect

The residual effects of several reduced-risk and conventional miticides were evaluated in strawberries (Fragaria z ananassa Duchesne) on the twospotted spider mite (TSSM), Tetranychus urticae Koch (Acari: Tetranychidae) and on 2 predatory mites, Neoseiulus californicus McGregor and Phytoseiulus persimilis Athias-Henriot (Acari: Phytoseiidae). Experiments were conducted in the laboratory and greenhouse. The greenhouse experiments also tested the direct effects of the miticides on TSSM. The efficacy of conventional and reduced-risk miticides was evaluated on strawberry leaf discs and on whole plants for control of TSSM. Furthermore, the residual effects of these miticides were evaluated on whole strawberry plants against selective predatory mites. For TSSM, 5 treatments were evaluated: a conventional miticide; fenbutatin-oxide (Vendex[reg]) and 3 reduced-risk miticides; binfenazate (Acramite 50WP[reg]), activated garlic extract (Repel[reg]), sesame seed and castor oil (Wipeout[reg]), and a water-treated control. For predatory mites, the residual effects of only Acramite[reg] and Vendex[reg] were evaluated. Acramite[reg] was the most effective acaricide in reducing TSSM populations in both the laboratory and greenhouse experiments. Vendex[reg] and Wipeout[reg] were also effective in the laboratory, but did not cause significant reduction of TSSM in the greenhouse. Repel[reg] was the least effective of the 4 pesticides evaluated. Neither Acramite[reg] nor Vendex[reg] had a significant effect on either predatory mite species. However, there appeared to be more predatory mites on the Vendex[reg]-treated plants than on the Acramite[reg]-treated plants. There were significantly more predatory mites of both species on the cue plants, which were inoculated with TSSM versus the non-cue plants, which were not inoculated. (author) [Spanish] Los efectos residuales en poblaciones de la 'arana roja', Tetranychus urticae Koch (Acari: Tetranichidae) y de los acaros predadores Neoseiulus californicus McGregor y Phytoseilus persimilis Athias-Henriot (Acari: Phytoseiidae) causados por varios acaricidas convencionales y de riesgo-reducido fueron evaluados en fresas (Fragaria x ananassa Duchense). Los experimentos fueron realizados en laboratorio e invernadero. Los experimentos en el invernadero evaluaron tambien el efecto directo de los acaricidas en la 'arana roja'. La eficacia para controlar la 'arana roja' de los acaricidas convencionales y de riesgo-reducido fue evaluada en discos de las hojas y en plantas de fresa, y los efectos residuales de los acaricidas en los acaros predadores fueron evaluados en plantas completas. Para la 'arana roja' se evaluaron cinco tratamientos: el acaricida convencional fenbutatin-oxido (Vendex[reg]), 3 acaricidas de riesgo-reducido binfenazate (Acaramite 50WP[reg]), extracto de ajo activado (Repel[reg]), aceite de semillas de ajonjoli y ricino (Wipeout[reg]) y un control tratado con agua. Para los acaros predadores solamente los efectos de Acaramite[reg] y Vendex[reg] fueron evaluados. Acaramite[reg] fue el tratamiento mas efectivo para la 'arana roja' en el laboratorio y el invernadero. Vendex[reg] y Wipeout[reg] fueron tambien efectivos en el laboratorio, pero no causaron una reduccion significativa de 'aranas rojas' en el invernadero. Repel[reg] fue el tratamiento evaluado menos eficaz. Ni Acaramite[reg] ni Vendex[reg] redujeron significativamente las poblaciones de acaros predadores. Sin embargo, aparentemente hay mas acaros predadores en Vendex[reg] que en Acaramite[reg]. Tambien se encontraron significativamente mas acaros predadores en plantas inoculadas que en plantas no inoculadas. (author)

Use of black vulture (Coragyps atratus) in complementary and alternative therapies for cancer in Colombia: A qualitative study  

PubMed Central

Background Although Coragyps atratus has been used as a traditional therapy for patients with cancer, the scientific literature does not contain enough information on how this therapy is used or the mechanisms that explain this therapeutic practice. Objectives To understand the methods of use and the reasons given by patients and caregivers for the use of Coragyps atratus in cancer treatment. Methods This study used a qualitative design based on twenty in-depth interviews of patients with cancer or caregivers of patients with the disease. The analysis of the text was based on an inductive thematic approach. Results Resistance to disease and immune enhancement are properties attributed to Coragyps atratus when used for cancer treatment. The most recommended method of use is fresh blood ingestion, and the associated mechanism of action is transfer of immune factors to the individual who consumes it. Conclusions Use of Coragyps atratus as a treatment for cancer is a popular alternative therapy in Colombia. More studies are needed to understand the clinical effects of this intervention in cancer patients. Spanish abstract Introducción Aunque Coragyps atratus se usa tradicionalmente como terapia para pacientes con cáncer, no existe suficiente información en la literatura científica sobre su forma de utilización ni sobre los mecanismos explicativos que subyacen a esta práctica terapéutica.

Promoting cultural humility during labor and birth: putting theory into action during PRONTO obstetric and neonatal emergency training.  

PubMed

Maternal and neonatal mortality in Northern Guatemala, a region with a high percentage of indigenous people, is disproportionately high. Initiatives to improve quality of care at local health facilities equipped for births, and increasing the number of births attended at these facilities will help address this problem. PRONTO (Programa de Rescate Obstétrico y Neonatal: Tratamiento Óptimo y Oportuno) is a low-tech, high-fidelity, simulation-based, provider-to-provider training in the management of obstetric and neonatal emergencies. This program has been successfully tested and implemented in Mexico. PRONTO will now be implemented in Guatemala as part of an initiative to decrease maternal and perinatal mortality. Guatemalan health authorities have requested that the training include training on cultural humility and humanized birth. This article describes the process of curricular adaptation to satisfy this request. The PRONTO team adapted the existing program through 4 steps: (a) analysis of the problem and context through a review of qualitative data and stakeholder interviews, (b) literature review and adoption of a theoretical framework regarding cultural humility and adult learning, (c) adaptation of the curriculum and design of new activities and simulations, and (d) implementation of adapted and expanded curriculum and further refinement in response to participant response.

Life Course Experiences, Pain and Suffering: A Case Study of an Older Mexican American Woman with Mobility Impairment  

PubMed Central

There is a dearth of literature examining how adversity shapes the experiences of pain and/or suffering in a middle aged Mexican American women. The purpose of this qualitative descriptive study was to understand pain and suffering from a life course perspective as described by a Mexican American woman aging with early onset mobility impairment. This Hispanic woman experienced episodes of abuse and rejection over the life course, which may have significantly influenced her pain and suffering experience in adulthood. This adds to the literature on how adversity influences later life pain experience and provides insight on why pharmacological treatment alone may not be as successful as a holistic intervention. Hay escasez de literatura que examine cómo la adversidad da forma a las experiencias de dolor y / o sufrimiento en mujeres mexicana-americana mayores de edad. El propósito de este estudio descriptivo cualitativo fue comprender el dolor y el sufrimiento desde una perspectiva de ciclo de vida como descrito por una mujer mexicana-americana envejeciendo con inicio temprano de deterioro de movilidad. Esta Latina experimentó episodios de maltrato y rechazo, que se percibió haber afectado su experiencia de dolor y sufrimiento luego como adulta. Este estudio aumenta la literatura sobre cómo la adversidad influya la experiencia de dolor más tarde en la vida, y nos permite comprender mejor como el tratamiento farmacológico por sí solo no es tan exitoso como pueda ser una intervención integral.

Descompresión microvascular en neuralgia del trigémino: Reporte de 36 casos y revisión de la literatura  

PubMed Central

Objetivo: El propósito del presente trabajo es presentar los resultados de 36 pacientes con diagnóstico de neuralgia del trigémino (NT), en los cuales se realizó una descompresión microvascular (DMV). Material y Método: Desde junio de 2005 a mayo de 2012, 36 pacientes con diagnóstico de NT fueron operados por el primer autor (AC), realizando una DMV. Se evaluó: Edad, sexo, tiempo de sintomatología previo a la cirugía, hallazgos intraoperatorios (a través de los videos quirúrgicos), y resultados postoperatorios. Resultados: De los 36 pacientes operados, 25 fueron mujeres y 11 varones. El promedio de edad fue de 48 años. El seguimiento postoperatorio fue en promedio de 38 meses. De los 36 pacientes, 32 (88%) evolucionaron sin dolor hasta la fecha. De los 4 casos con recurrencia de dolor, en dos pacientes se observó como hallazgo intraoperatorio un conflicto venoso. Conclusión: La DMV como tratamiento de la NT es un procedimiento efectivo y seguro. El hallazgo intraoperatorio de una “compresión” venosa podría indicar una evolución postoperatoria desfavorable.

Cirug?a transnasal endosc?pica para tumores de hip?fisis  

PubMed Central

Introducción: Exponer la técnica utilizada y los resultados obtenidos en los primeros 52 pacientes portadores de tumores hipofisarios tratados por la vía endoscópica transnasal en el Hospital Italiano de Buenos Aires Métodos: Se llevó a cabo un análisis retrospectivo de 52 cirugías endoscópicas transnasales utilizadas en el tratamiento de tumores hipofisários. Las mismas fueron realizadas en el Hospital Italiano de Buenos Aires durante el período junio del 2011 a junio del 2012. Se analizaron las características demográficas de los pacientes, la patología de base y la morbimortalidad asociada a la cirugía. Resultados: La edad media de los pacientes fue de 41,52 años con un rango de 18-79. La distribución fue similar entre hombres y mujeres. Las patologías más frecuentes fueron: adenomas no funcionantes (40.4%), tumores productores de GH/Acromegalia (25%) y tumores productores de ACTH/Enfermedad de Cushing (23.1%). Aproximadamente el 70 % correspondieron a macroadenomas. Sólo un paciente presentó complicaciones. No se registro ningún óbito. Conclusión: Si bien podremos objetivar fehacientemente resultados más concluyentes en futuros trabajos, podemos decir a priori que, en la endoscopía el detalle anatómico es claramente superior al microscópico y que la posibilidad de la introducción del endoscopio en la silla turca permite la visualización directa de remanentes tumorales, de sitios de fístula y como así también de la glándula normal, ventajas que potencialmente podrían permitir obtener mejores resultados quirúrgicos, en términos de control de la enfermedad y tasa de complicaciones.

Cirug?a de los trastornos del comportamiento: el estado del arte  

PubMed Central

Introducción: La cirugía de los trastornos del comportamiento (CTC) se está convirtiendo en un tratamiento más común desde el desarrollo de la neuromodulación. Métodos: Este artículo es una revisión no sistemática de la historia, indicaciones actuales, técnicas y blancos quirúrgicos de la CTC. Dividimos su historia en 3 eras: la primera comienza en los inicios de la psicocirugía y termina con el desarrollo de las tícnicas estereotácticas, cuando comienza la segunda era. Ésta se caracteriza por la realización de lesiones estereotácticas. Nos encontramos transitando la tercera era, que comienza cuando la estimulación cerebral profunda (ECP) comienza a ser usada en CTC. Resultados: A pesar de los errores graves cometidos en el pasado, hoy en día, la CTC está renaciendo. Los trastornos psiquiátricos que se más frecuentemente se tratan con cirugía son: depresión refractaria, trastorno obsesivo-compulsivo y síndrome de Tourette. Además, algunos pacientes con agresividad fueron tratados quirúrgicamente. Hay varios blancos estereotácticos descriptos para estos trastornos. La estimulación vagal puede ser usada también para depresión. Conclusión: Los resultados de la ECP en estos trastornos parecen alentadores. Sin embargo, se necesitan más estudios randomizados para establecer la efectividad de la CTC. Debe tenerse en cuenta que una apropiada selección de pacientes nos ayudará a realizar un procedimiento más seguro así como también a lograr mejores resultados quirúrgicos, conduciendo a la CTC a ser más aceptada por psiquiatras, pacientes y sus familias. Se necesita mayor investigación en varios temas como: fisiopatología de los trastornos del comportamiento, indicaciones de CTC y nuevos blancos quirúrgicos. PMID:25165612

Climate change impacts on groundwater resources: modelled deficits in a chalky aquifer, Geer basin, Belgium  

NASA Astrophysics Data System (ADS)

An integrated hydrological model (MOHISE) was developed in order to study the impact of climate change on the hydrological cycle in representative water basins in Belgium. This model considers most hydrological processes in a physically consistent way, more particularly groundwater flows which are modelled using a spatially distributed, finite-element approach. Thanks to this accurate numerical tool, after detailed calibration and validation, quantitative interpretations can be drawn from the groundwater model results. Considering IPCC climate change scenarios, the integrated approach was applied to evaluate the impact of climate change on the water cycle in the Geer basin in Belgium. The groundwater model is described in detail, and results are discussed in terms of climate change impact on the evolution of groundwater levels and groundwater reserves. From the modelling application on the Geer basin, it appears that, on a pluri-annual basis, most tested scenarios predict a decrease in groundwater levels and reserves in relation to variations in climatic conditions. However, for this aquifer, the tested scenarios show no enhancement of the seasonal changes in groundwater levels. Un modèle hydrologique intégré (MOHISE) a été développé afin d'étudier l'impact du changement climatique sur le cycle hydrologique de bassins versants représentatifs de Belgique. Ce modèle prend en compte tous les processus hydrologiques d'une manière physiquement consistante, plus particulièrement les écoulements souterrains qui sont modélisés par une approche spatialement distribuée aux éléments finis. Grâce à cet outil numérique précis, après une calibration et une validation détaillées, des interprétations quantitatives peuvent être réalisées à partir des résultats du modèle de nappe. Considérant des scénarios de changements climatiques de l'IPCC, l'approche intégrée a été appliquée pour évaluer l'impact du changement climatique sur le cycle de l'eau du bassin du Geer en Belgique. Le modèle de nappe est décrit en détail et les résultats sont discutés en terme d'impact du changement climatique sur l'évolution des réserves souterraines. Les premiers résultats indiquent que des déficits d'eau souterraine peuvent apparaître dans le futur en Belgique. Se ha desarrollado un modelo hidrológico integrado (MOHISE) para estudiar el impacto del cambio climático en el ciclo hidrológico de cuencas representativas en Bélgica. Este modelo considera todos los procesos hidrológicos de forma coherente, especialmente en relación con los flujos de aguas subterráneas, que son modelados por medio de un enfoque de elementos finitos espacialmente distribuidos. Gracias a esta herramienta numérica precisa, y tras una calibración y validación detalladas, se puede obtener interpretaciones cuantitativas de los resultados del modelo del acuífero. Considerando escenarios de cambio climático IPCC, se ha aplicado el enfoque integrado a la evaluación del impacto de dicho cambio climático en el ciclo hidrológico de la cuenca del Geer. Se describe los detalles y resultados del modelo de las aguas subterráneas en términos del impacto del cambio climático en la evolución de las reservas de los acuíferos. Los resultados preliminares indican que es posible esperar déficits de aguas subterráneas en un futuro en Bélgica.

Medicinal ethnobotany in Huacareta (Chuquisaca, Bolivia)  

PubMed Central

Background The aim of this study was to document the types of diseases treated by the use of medicinal plants, their main applications and also to have a report of the major diseases treated at the Hospital of San Pablo de Huacareta (Chuquisaca Bolivia). Methods We conducted semi-structured interviews on the use medicinal plants with 10 local informants, and categorized the kinds of diseases treated by traditional medicine. We obtained reports of cases treated at the Hospital of Huacareta in order to compare the use frequency of traditional medicine and allopathic medicine for the treatment of recurrent diseases in the area. Results Our survey identified 258 traditional medicine uses, spanning a total of 13 diseases categories and including 91 native and exotic plant species and one unidentified sample plant type. Gastrointestinal disorders (55%) were most frequently treated with medicinal plants, followed by afflictions of the musculoskeletal system (25%) and dermatological disorders (24%). Hospital information indicates that the most common diseases are acute respiratory infections (47%) and acute diarrheal diseases (37%). The herbal remedies were mostly used in the form of teas and decoctions. The informants used mainly native plant species, although exotic species has been introduced to the pharmacopoeia. Conclusions The treatment of gastrointestinal disorders is the primary objective of the medical ethnobotany of the inhabitants of Huacareta, while respiratory system diseases are mostly treated in the hospital. Looking at the data from the Hospital records we can infer that gastrointestinal disorders are among the most common diseases in the study area. For most respondents, traditional medicine is a reliable choice for the care of their illnesses. However, the preference of the population for either traditional medicine or allopathic medicine needs to be clarified in future comparative studies to obtain more convincing results. The results presented can be used as a base for subsequent work related to traditional medicine and its contribution to allopathic medicine in San Pablo de Huacareta. Resumen Introducción El objetivo del presente estudio fue documentar los tipos de enfermedades tratadas mediante el uso de plantas medicinales, sus aplicaciones principales y también tener un reporte de las enfermedades mayormente atendidas en el Hospital de San Pablo de Huacareta (Chuquisaca, Bolivia). Métodos Se realizaron encuestas semiestructuradas a 10 informantes locales anotando los usos atribuidos a sus plantas medicinales, se agruparon las plantas por categorías de enfermedades tratadas en la medicina tradicional. Se obtuvieron reportes de casos tratados en el Hospital de Huacareta para poder relacionar el tratamiento de enfermedades recurrentes en la zona entre la medicina tradicional y la medicina occidental. Resultados Se reportaron 91 especies nativas y exóticas, además de un espécimen indeterminado exótico que intervienen en un total de 258 aplicaciones medicinales, las cuales son empleadas en un total de 13 categorías de enfermedades. Los desórdenes gastrointestinales (55%) son mayormente tratados mediante plantas medicinales, seguidas de las afecciones al sistema esqueleto-muscular (25%) y enfermedades dermatológicas (24%). La información del Hospital indica que las enfermedades más frecuentes son Infecciones Respiratorias Agudas (47%) y Enfermedades Diarreicas Agudas (37%). Los remedios vegetales se emplean en forma de infusiones y cocciones principalmente. Se emplean mayormente plantas nativas, también se introdujo en la farmacopea médica el uso de plantas exóticas al lugar. Conclusiones El tratamiento de trastornos gastrointestinales constituye el objetivo primordial de la etnobotánica médica de los habitantes de Huacareta, las enfermedades del sistema respiratorio, son mayormente tratadas en el Hospital. Observando los datos del libro de consultas del Hospital, se puede inferir que los desórdenes gastrointestinales

Reacciones de intercambio de carga  

NASA Astrophysics Data System (ADS)

Se discute la validez de diversas metodologías y su aplicación al estudio de procesos de intercambio de carga electrónico entre iones y blancos atómicos y moleculares. Para energías de impacto entre 0.05 y 5 eV / amu se emplea el método cuántico de la Coordenada de Reacción Común (CRC). A mayores energías, se utiliza el método semiclásico iconal con un desarrollo de la función de onda dinámica en estados moleculares adiabáticos, modificados con un factor de traslación común (FTC). Estos estados pueden obtenerse con cálculos ab initio o empleando potenciales modelo. Cuando la ionización compite con la transferencia de carga, la inclusión de pseudoestados en estos desarrollos permite calcular simultáneamente las secciones eficaces de ambos procesos. Otra técnica utilizada es el método estadístico CTMC. En el tratamiento de colisiones ión-molécula (diatómica) contrastamos la aplicabilidad de distintos métodos, desde la llamada aproximación Franck-Condon hasta un desarrollo en estados vibrónicos, pasando por la aproximación súbita vibro-rotacional, obteniéndose secciones eficaces de captura electrónica total y a estados individuales, así como secciones de excitación vibracional a estados ligados y del continuo (disociación). En todos los casos es necesario calcular superficies de energía y los correspondientes acoplamientos dinámicos entre los estados. La aplicación de estos métodos permite determinar el grado de contaminación de los haces por estados metaestables en un experimento dado, el cambio en los resultados con diferentes isótopos, la importancia de procesos de doble captura, seguida de explosión culombiana, todo ello con precisión comparable a la de medidas experimentales, para sistemas de interés en distintos tipos de plasmas.

Regulando la Enfermedad a trav?s de la Definici?n y la Restricci?n: Profesionales de la Salud Hablan sobre el VIH/SIDA1  

PubMed Central

Resumen Las profesiones de la salud tienen un papel social dual. Por un lado, velan por el mantenimiento de la salud de la población protegiendo el bien común. Por el otro, dictaminan las formas saludables, y por lo tanto socialmente apropiadas, de ser, actuar y pensar. Este último papel, está más ligado al control social de la población que a una preocupación altruista hacia la misma. A través de esta supervisión y control, se construyen los sujetos a los cuales todos/as debemos aspirar a ser para gozar de aceptación social. Los/as profesionales de la salud han jugado un rol protagónico en dicho proceso, siendo los agentes que delimitan y definen lo que es enfermo vs. saludable, útil vs. inútil, apropiado vs. inapropiado. En el caso de la epidemia del VIH, este esfuerzo se ha hecho cada vez más vigente ya que estos/as profesionales juegan un papel importante en el tratamiento de las personas que viven con VIH/SIDA (PVVS). Sin embargo, su función está plasmada de definiciones que sirven para criminalizar a las PVVS. El objetivo de este estudio fue explorar la manera en que una muestra de profesionales de la salud en Puerto Rico construyen a las PVVS. Con este propósito, entrevistamos 80 profesionales de la salud y estudiantes de estas profesiones. Estas entrevistas fueron grabadas, transcritas y sometidas a un análisis de discurso. Los resultados reflejaron que según las personas participantes: 1) la PVVS no es una persona “normal” o funcional bajo los estándares sociales debido a que su salud no se los permite, 2) representa una carga para la sociedad incluyendo familiares, amigos/as, el mundo del trabajo, e incluso para el gobierno, 3) debe ser vigilada porque representa un riesgo para la persona seronegativa que es descrita como saludable y productiva, y 4) necesita que su salud y conducta sexual sean controladas por vía legal y/o por las personas que representan las instituciones sociales, como lo son los/as profesionales de la salud. En este artículo abordamos el potencial rol de la psicología para servir como vehículo de reconstrucción de dichas nociones, tomando en consideración su propio rol en la formación y mantenimiento de dicho sujeto socialmente deseable.

Progress in the prognosis of adult Hodgkin's lymphoma in the past 35 years through clinical trials in Argentina: a GATLA experience.  

PubMed

The purpose of this study was to evaluate the trends in complete remission (CR) rate, disease-free survival (DFS), and overall survival (OS) through 35 years of Grupo Argentino de Tratamiento de la Leucemia Aguda (GATLA) clinical trials. A total of 1,254 adult patients with Hodgkin's Lymphoma were evaluated according to seven consecutive protocols. This 35-year study was divided into three phases. The patients in the first phase (1968-1985) were treated with CVPP (cyclophosphamide/vinblastine/procarbazine/prednisone) plus involved-field radiotherapy (IFRT). In the CVPP regimen, cyclophosphamide and vinblastine were administered intravenously on day 1 and prednisone and procarbazine were administered orally on days 1-14 every 28 days. The second phase (1986-1996) used mainly reinforced CVPP with cyclophosphamide and vinblastine on days 1-8 plus IFRT. The third phase (1997-2003) used ABVD(doxorubicin/bleomycin/vinblastine/dacarbazine) plus IFRT. In clinical stage I/II, the CR rate was 86% in 252 patients treated in the first phase and DFS and OS were 57% and 78% at 5 years and 50% and 71% at 10 years. The second phase had 148 patients with clinical stage I/II disease, and the CR rate was 91%, 5-year DFS and OS were 78% and 90%, and 10-year DFS and OS were 70% and 83%. The third phase had 182 patients with clinical stage I/II disease, and the CR rate was 95%, 5-year DFS and OS were 87% and 96%, and 10-year DFS and OS were not reached. The statistical difference was P = 0.016 in terms of CR and P < 0.001 in terms of DFS and OS. In the first phase of 394 patients with clinical stage III/IV disease, the CR rate was 71%, DFS and OS at 5 years were 37% and 62%, and DFS and OS at 10 years were 32% and 53%. In the second phase of 164 patients with clinical stage III/IV disease, the CR rate was 84%, DFS and OS at 5 years were 66% and 80%, and DFS and OS at 10 years were 60% and 75%. In the third phase of 114 patients with clinical stage III/IV disease, the CR rate was 88% and DFS and OS at 5 years were 60% and 90%. The DFS and OS were not reached at 10 years. The differences among the 3 phases in CR, DFS and OS were highly significant (P < 0.001). PMID:15453925

Modelizacion, control e implementacion de un procesador energetico paralelo para aplicacion en sistemas multisalida  

NASA Astrophysics Data System (ADS)

Cualquier sistema electronico que incluya un procesado o tratamiento de la senal, y ademas, algun tipo de actuador mecanico generalmente necesita, como minimo, dos tensiones diferentes de alimentacion. Excluyendo los sistemas de alimentacion distribuida, la solucion tecnica mas utilizada para proporcionar dos o mas tensiones consiste en las fuentes de alimentacion multisalida. En una fuente de alimentacion multisalida los diferentes circuitos que conforman cada salida comparten un mismo transformador de potencia optimizando coste, masa, y volumen. Las ventajas obtenidas con este procedimiento tienen en su contra el efecto que sobre cada salida individual provocan las demas en su conjunto debido, principalmente, a los efectos de los elementos parasitos de los componentes. Un cambio de carga en una de las salidas produce un transitorio que es visto por todas las demas como un efecto de impedancia cruzada, y al final del transitorio, la tension de cada salida es diferente respecto a la que tenian antes del transitorio. Este ultimo resultado se conoce como regulacion cruzada. La disminucion de los efectos de la regulacion cruzada ha sido objeto de estudio durante los ultimos anos. El objetivo ha sido el desarrollo de distintas estrategias que permiten, desde disminuir los efectos de la regulacion cruzada hasta los niveles deseables, a eliminarla completamente. El resultado final suele suponer una penalizacion sobre el diseno del sistema directamente proporcional al grado de regulacion a conseguir en las distintas salidas. Entre las soluciones propuestas para eliminar la regulacion cruzada las tecnicas de post-regulacion se han consolidado como la opcion mas aceptada ya que, pueden aplicarse a cualquier convertidor y no suponen ninguna complejidad adicional a la hora de plantear el diseno. En esta Tesis Doctoral se abordara el estudio de la tecnica conocida como postregulacion mediante transformador controlado, que si bien se ha empleado en convertidores resonantes, su modelizacion, y aplicacion en convertidores PWM, esta aun por estudiar y valorar. El primer Capitulo consiste en una breve introduccion al problema de la regulacion cruzada y la impedancia cruzada para posteriormente describir las tecnicas de post-regulacion actualmente mas empleadas, con especial atencion al post-regulador con transformador controlado. El Capitulo segundo trata del estudio de las caracteristicas estaticas del postregulador con transformador controlado. Partiendo de los estudios disponibles sobre el postregulador se plantean mejoras en su modo de actuacion y se discuten tres alternativas diferentes para controlar el transformador. Las dos primeras consisten en emplear un convertidor auxiliar Boost en sus dos modos de funcionamiento, continuo y discontinuo. La tercera consiste en controlar el transformador con una tension PWM directamente, sin filtrado. Finalmente se comprueba experimentalmente, para el estado estacionario, el funcionamiento del post-regulador para cada uno de los tres metodos de control. El Capitulo tercero trata de la dinamica de la salida controlada con el post-regulador cuando este emplea un convertidor auxiliar tipo Boost. Mediante la tecnica de promediado de variables de estado se propone el modelo de pequena senal, tanto para el modo continuo como para el modo discontinuo de funcionamiento del convertidor auxiliar. Los resultados mas significativos de esta seccion son las expresiones analiticas de las impedancias cruzadas y de la impedancia de la salida post-regulada. Como complemento al modelo de pequena senal se plantea un modelo de gran senal implementado sobre el simulador Pspice. Con este nuevo modelo se reproducen los resultados obtenidos con el modelo de pequena senal y ademas es posible simular los transitorios en las tensiones de salida ante cambios de carga. La modelizacion del convertidor cuando el transformador se controla con una tension PWM sin filtrar es el objetivo del Capitulo 4. En las secciones siguientes del Capitulo se plantea el correspondiente modelo de gran senal aplicado a un nuevo prototipo exper

Impact of Chloroquine on Viral Load in Breast Milk  

PubMed Central

Summary The anti-malarial agent chloroquine has activity against HIV. We compared the effect of chloroquine (n = 18) to an anti-malarial agent without known anti-HIV-activity, sulfadoxine-pyrimethamine (n = 12), on breast milk HIV RNA levels among HIV-infected breastfeeding women in Zambia. After adjusting for CD4 count and plasma viral load, chloroquine was associated with a trend towards lower levels of HIV RNA in breast milk compared with sulfadoxine-pyrimethamine (P 0.05). Higher breastmilk viral load was also observed among women receiving presumptive treatment = for symptomatic malaria compared with asymptomatic controls and among controls reporting fever in the prior week. Further research is needed to determine the potential role of chloroquine in prevention of HIV transmission through breastfeeding. Impacte de la chloroquine sur la charge virale dans le lait maternelle La chloroquine, agent antimalarique, a une activité contre le VIH. Nous avons comparé l’effet de la chloroquine à celui d’un autre agent antimalarique, la sulfadoxine-pyrimethamine, dont l’activité sur le VIH n’est pas connue, en mesurant les taux d’ARN de VIH dans le lait maternel de femmes allaitantes infectées par le VIH en Zambie. Après ajustement pour les taux de CD4 et la charge virale dans le plasma, la chloroquine comparée à la sulfadoxine pyrimethamine était associée à une tendance vers des teneurs plus bas en ARN de VIH dans le lait maternel (P = 0,05). Des charges virales plus élevées dans le lait maternel étaient aussi observées chez des femmes recevant un traitement présomptif pour des symptômes de malaria par rapport aux contrôles asymptomatiques et par rapport à des contrôles rapportant de la fièvre durant la première semaine. Des études supplémentaires sont nécessaires pour déterminer le rôle potentiel de la chloroquine dans la prévention de la transmission du VIH par l’allaitement maternel. mots clésVIH, malaria, allaitement maternel, chloroquine, sulfadoxine-pyrimethamine, charge virale du lait maternel, fièvre Impacto de la cloroquina en la carga viral de la leche materna El antimalárico cloroquina tiene actividad frente al VIH. Comparamos el efecto de la cloroquina (n = 18) frente a un antimalárico sin actividad anti-VIH conocida, la sulfadoxina-pirimetamina (n = 12), en los niveles de ARN en la leche materna de mujeres infectadas con VIH, en Zambia. Después de ajustar para recuento de CD4 y la carga viral en plasma, se asoció a la cloroquina con una tendencia hacia menores niveles de ARN del VIH en leche materna, comparado con la sulfadoxina pirimetamina (P = 0.05). También se observó una mayor carga viral en la leche materna de mujeres recibiendo tratamiento presuntivo para malaria sintomática, que en los controles asintomáticos y controles que habáan reportado fiebre la semana anterior. Es necesario realizar más estudios para determinar el papel potencial de la cloroquina en la prevención de la trasmisión de VIH a través de la lactancia materna. palabras claveVIH, malaria, lactancia materna, cloroquina, sulfadoxina pirimetamina, transmisión vertical, leche materna, carga viral, fiebre PMID:16772000

The effects of training in time-limited dynamic psychotherapy: changes in therapeutic outcome.  

PubMed

The present study explored the effects on therapeutic outcomes of training therapists in brief manualized therapy. As part of the Vanderbilt II project, each of 16 therapists (8 psychiatrists and 8 clinical psychologists) treated 2 moderately disturbed adult patients using his or her customary short-term treatment methods; they then received a year of training in a manualized form of brief dynamic therapy, Time-Limited Dynamic Psychotherapy (TLDP); finally, they administered TLDP to 2 additional patients. It was hypothesized that training would result in improved outcomes generally and that differentially greater improvement would be seen in patients commonly considered less suitable for brief dynamic therapy. Outcome data obtained at termination failed to support either hypothesis. Measurements of interpersonal dependency obtained at a one-year follow-up were consistent with the first hypothesis, but the follow-up data were inconsistent with the second. A systematic review of the 32 posttraining cases suggested that the majority of the therapists had not achieved basic competence at TLDP. Die hier beschriebene Studie untersucht die Wirkungen eines Trainings in manualisierter Kurzzeitherapie auf das Therapierergebnis. Als Teil des Vanderbilt II Projektes behandelten jeweils 16 Therapeuten (8 Psychiater und 8 klinische Psychologen) zwei mittelgradig beeinrächtigte erwachsene Patienten mit den ihnen vertrauten Kurzzeitbehandlungsmethoden. Danach wurden sie über ein Jahr in einer manualisierten Form psychodynamischer Kurzzeittherapie ausgebildet und wandten diese Therapie auf zwei weitere Patienten an. Es wurde angenommen, dass die Ausbildung in besseren Ergebnisdaten, die bei Ende der Therapie erhoben wurden, konnten diese Hypothese nicht bestätigen. Maße für die interpersonale Abhängigkeit zu einem Einjahreskatamnesezeitpunkt waren mit der ersten Hypothese konform, aber inkonsistent mit der zweiten. Eine systematische Untersuchung der 32 nach der Ausbildung behandelten Fälle legt nahe, dass die Mehrzahl der Therapeuten keine grundlegende Kompetenz in zeitlich limitierter dynamischer Psychotherapie erworben hatte. Cette éude explore les effets sur les résultats thérapeutiques de la formation des thérapeutes dans une thérapie brève, manualissée. Dans le cadre du projet Vanderbilt II, chacun des 16 thérapeutes (8 psychiatrs et 8 psychologues cliniciens) a traité deux patients adultes modérément perturbés, chacun par sa méthode habituelle de thérapie brève; ensuite ils ont reçu une formation d'une année dans une méthode manualisée de thérapie brève, la Psychothérapie Dynamique Limitée dans le Temps (TLDP); pour finir, ils ont appliqué la TLDP à de meilleurs résultats en général, et qu'une amélioration comparativement plus importante sera observée chez des patients habituellement considérés comme moins adaptés à une thérapie dynamique brè. Les résultats obtenus à la terminaison n'ont pu confirmer aucune de ces hypothèses. Des mesures de la dépendance interpersonnelle une année après étaient consistantes avec la première hypothèse, mais les données catamnestiques étaient inconsistantes avec la deuxième. Une revue systématique des 32 cas après formation a suggéré que la majorité des thérapeutes n'avait pas acquis une compétence de base en TLDP. Este estudio exploró la efectividad del entrenamiento de terapeutas en una terapia breve manualizada. Como parte del proyecto Vanderbilt II, dieciséis terapeutas (ocho psiquiatras y ocho psicólogos clínicos) trataron dos pacientes adultos mooderadamente perturbados con sus métodos habituales de tratamiento a corto plazo. Estos terapeutas recibieron luego un año de entrenamiento en terapia dinámica breve manualizada que se Ilamó Psicoterapia Dinámica de Tiempo limitado (TLDP). Finalmente, administraron esta TLDP a dos pacientes más. La hipótesis fue que el entrenamiento ilevaría, en general, a resultados mejores y que habría mayor mejoramiento en pacientes menos aptos para una terapia dinámica breve. Los resultados
