This is a short note reporting on the current state of development of the temperature sensors which are part of the LTP Diagnostics Subsystem on board the LISA Pathfinder mission (LPF). A thermal insulator has been designed which ensures sufficient stability of a set of eight NTC sensors (negative temperature coefficient of resistance or thermistors), and the front-end electronics has also been designed and manufactured. Tests have been performed which nearly approach the goal of a global stability of 10 -5 K Hz -1/2
The primary objective of the LISA (Laser Interferometer Space Antenna mission is the detection and observation of gravitational waves from massive black holes (MBH) and galactic binaries in the frequency range 10 -4 Hz ... 10 -1 Hz. This low-frequency range is inaccessible to ground-based interferometers due to the background of local gravitational noise and because ground-based interferometers are limited in length to a few kilometres. LISA is envisaged as an ESA/NASA collaborative project, selected an ESA cornerstone mission and included in NASA's strategic plan and with a nominal launch date in 2011. SMART-2 is primarily intended to demonstrate the key technologies for the ESA/NASA collaborative LISA cornerstone mission. The synergy with the technology being used for Darwin motivates the utilization of SMART-2 for both missions. To this end, SMART-2 will accommodate a LISA technology package (LTP), provided by European institutes and industry and possibly also a Disturbance Reduction System (DRS) that is very similar to the LTP and has the same goals but is provided by US institutes and industry

The LISA Technology Package (LTP), to be launched by ESA in 2006/2007, is a technology demonstration mission in preparation for the LISA space-borne gravitational wave detector. A central part of the LTP is the optical metrology package (heterodyne interferometer with phasemeter) which monitors the distance between two test masses with a noise level of 10 pm Hz -1/2 between 3 mHz and 30 mHz. It has a dynamic range of >100 μm without any actuators for the pathlength. In addition to the longitudinal measurements, it provides alignment measurements with an expected noise level of -1/2 . While the basic design has been described previously by Heinzel et al (2003 Class. Quantum Grav. 20 S153-61), this paper gives new details on the laser stabilization, the phasemeter and recent prototype results
Full Text Available Lipoprotein Ltp encoded by temperate Streptococcus thermophilus phage TP-J34 is the prototype of the wide-spread family of host cell surface-exposed lipoproteins involved in superinfection exclusion. When screening for other S. thermophilus phages expressing this type of lipoprotein, three temperate phages - TP-EW, TP-DSM20617 and TP-778 - were isolated. In this communication we present the total nucleotide sequences of TP-J34 and TP-778L. For TP-EW, a phage almost identical to TP-J34, besides the ltp gene only the two regions of deviation from TP-J34 DNA were analyzed: the gene encoding the tail protein causing an assembly defect in TP-J34 and the gene encoding the lysin, which in TP-EW contains an intron. For TP-DSM20617 only the sequence of the lysogeny module containing the ltp gene was determined. The region showed high homology to the same region of TP-778. For TP-778 we could show that absence of the attR region resulted in aberrant excision of phage DNA. The amino acid sequence of mature LtpTP-EW was shown to be identical to that of mature LtpTP-J34, whereas the amino acid sequence of mature LtpTP-778 was shown to differ from mature LtpTP-J34 in eight amino acid positions. LtpTP-DSM20617 was shown to differ from LtpTP-778 in just one amino acid position. In contrast to LtpTP-J34, LtpTP-778 did not affect infection of lactococcal phage P008 instead increased activity against phage P001 was noticed.
Full Text Available When an organism is exposed to a stressful situation, corticosteroid levels in the brain rise. This rise has consequences for behavioral performance, including memory formation. Over the past decades, it has become clear that a rise in corticosteroid level is also accompanied by a reduction in hippocampal long-term potentiation (LTP. Recent studies, however, indicate that stress does not lead to a universal suppression of LTP. Many factors, including the type of stress, the phase of the stress response, the area of investigation, type of LTP, and the life history of the organism determine in which direction LTP will be changed.

Brightness preservation requirements for ever brighter synchrotron radiation and free electron laser beamlines require surface slope tolerances of x-ray optics on the order of 0.2 mu rad, or better. Hence, the accuracy of dedicated surface slope metrology must be 0.1 mu rad, or even less. Achieving this level of measurement accuracy with the flagship instrument at synchrotron radiation metrology laboratories, the Long Trace Profiler (LTP), requires all significant sources of systematic, random, and instrumental drift errors to be identified, and reduced or eliminated. In this respect, the performance of certain components of the Advanced Light Source LTP-II design [Kirschman, et al., Proc. SPIE, 7077, 70770A-12 (2008)] is analyzed, considering the principal justification for inclusion of each component, possible systematic error due to the quality of its optical material, and drift effects due to generated heat, etc. We investigate the effects of replacement of the existing diode laser with a fiber-coupled laser light source, and demonstrate that reducing the number of components by using a single beam on the surface under test (SUT), rather than an original double beam maintains, or even improves the accuracy of measurement with our LTP. Based on the performance of the upgraded LTP, we trace the further steps for improving of the LTP optical system.

LISA Pathfinder (LPF) is the precursor mission of LISA (Laser Interferometer Space Antenna) and the first step towards gravitational waves detection in space. The main instrument onboard the mission is the LTP (LISA Technology Package) whose scientific goal is to test LISA's drag-free control loop by reaching a differential acceleration noise level between two masses in √ geodesic motion of 3 × 10-14 ms-2 / Hz in the milliHertz band. The mission is not only challenging in terms of technology readiness but also in terms of data analysis. As with any gravitational wave detector, attaining the instrument performance goals will require an extensive noise hunting campaign to measure all contributions with high accuracy. But, opposite to on-ground experiments, LTP characterisation will be only possible by setting parameters via telecommands and getting a selected amount of information through the available telemetry downlink. These two conditions, high accuracy and high reliability, are the main restrictions that the LTP data analysis must overcome. A dedicated object oriented Matlab Toolbox (LTPDA) has been set up by the LTP analysis team for this purpose. Among the different toolbox methods, an essential part for the mission are the parameter estimation tools that will be used for system identification during operations: Linear Least Squares, Non-linear Least Squares and Monte Carlo Markov Chain methods have been implemented as LTPDA methods. The data analysis team has been testing those methods with a series of mock data exercises with the following objectives: to cross-check parameter estimation methods and compare the achievable accuracy for each of them, and to develop the best strategies to describe the physics underlying a complex controlled experiment as the LTP. In this contribution we describe how these methods were tested with simulated LTP-like data to recover the parameters of the model and we report on the latest results of these mock data exercises.

Since 2005 the Swiss Light Source (SLS) has been operating a Long Trace Profiler (LTP)-V from Ocean Optics in its metrology laboratory to measure the synchrotron optics for SLS. In 2012 we finished a significant upgrade to improve the accuracy, reliability and measurement efficiency in particular for the calibration of adaptive optics. Folding mirrors with figure errors <λ/100 and an additional linear encoder have been installed, the 1d CCD detector with 2048 pixels has been replaced by a 16 mega-pixel CCD camera with gigabit ethernet interface GigE, the monolithic software has been replaced by a modular, full- EPICS compatible system based on a new LTP plugin for the areaDetector software for image processing. The plugin allows slope determination in real time i.e. per frame.

Full Text Available Plant non-specific lipid transfer proteins (nsLTPs constitute large multigene families that possess complex physiological functions, many of which remain unclear. This study isolated and characterized the function of a lipid transfer protein gene, BraLTP1 from Brassica rapa, in the important oilseed crops Brassica napus. BraLTP1 encodes a predicted secretory protein, in the little known VI Class of nsLTP families. Overexpression of BnaLTP1 in B. napus caused abnormal green coloration and reduced wax deposition on leaves and detailed wax analysis revealed 17-80% reduction in various major wax components, which resulted in significant water-loss relative to wild type. BnaLTP1 overexpressing leaves exhibited morphological disfiguration and abaxially curled leaf edges, and leaf cross-sections revealed cell overproliferation that was correlated to increased cytokinin levels (tZ, tZR, iP, and iPR in leaves and high expression of the cytokinin biosynthsis gene IPT3. BnaLTP1-overexpressing plants also displayed morphological disfiguration of flowers, with early-onset and elongated carpel development and outwardly curled stamen. This was consistent with altered expression of a a number of ABC model genes related to flower development. Together, these results suggest that BraLTP1 is a new nsLTP gene involved in wax production or deposition, with additional direct or indirect effects on cell division and flower development.

The LISA Technology Package (LTP) uses laser interferometry to measure the changes in relative displacement between two inertial test masses. The goals of the mission require a displacement measuring precision of 10 pm Hz -1/2 at frequencies in the 3-30 mHz band. We report on progress with a prototype LTP interferometer optical bench in which fused silica mirrors and beamsplitters are fixed to a ZERODUR (registered) substrate using hydroxide catalysis bonding to form a rigid interferometer. The couplings to displacement noise of this interferometer of two expected noise sources-laser frequency noise and ambient temperature fluctuations-have been investigated, and an additional, unexpected, noise source has been identified. The additional noise is due to small amounts of signal at the heterodyne frequency arriving at the photodiode preamplifiers with a phase that quasistatically changes with respect to the optical signal. The phase shift is caused by differential changes in the external optical paths the beams travel before they reach the rigid interferometer. Two different external path length stabilization systems have been demonstrated and these allowed the performance of the overall system to meet the LTP displacement noise requirement

The ltp gene, located within the lysogeny module of temperate Streptococcus thermophilus phage TP-J34, has been shown to be expressed in lysogenic strain S. thermophilus J34. It codes for a lipoprotein, as demonstrated by inhibition of cleavage of the signal sequence by globomycin. Exposure of Ltp on the surface of Lactococcus lactis protoplasts bearing a plasmid-encoded copy of ltp has been demonstrated by immunogold labeling and electron microscopy. Expression of ltp in prophage- and plasmid-cured S. thermophilus J34-6f interfered with TP-J34 infection. While plating efficiency was reduced by a factor of about 40 and lysis of strain J34-6f in liquid medium was delayed considerably, phage adsorption was not affected at all. Intracellular accumulation of phage DNA was shown to be inhibited by Ltp. This indicates interference of Ltp with infection at the stage of triggering DNA release and injection into the cell, indicating a role of Ltp in superinfection exclusion. Expression of ltp in L. lactis Bu2-60 showed that the same superinfection exclusion mechanism was strongly effective against phage P008, a member of the lactococcal 936 phage species: no plaque-formation was detectable with even 10 9 phage per ml applied, and lysis in liquid medium did not occur. In Lactococcus also, Ltp apparently inhibited phage DNA release and/or injection. Ltp appears to be a member of a family of small, secreted proteins with a 42 amino acids repeat structure encoded by genes of Gram-positive bacteria. Some of these homologous genes are part of the genomes of prophages

This paper presents the current state of the LISA Technology Package (LTP) fibre injector qualification project in terms of vibration and shock tests. The fibre injector is a custom built part and therefore must undergo a full space qualification process. The mounting structure and method for sinusoidal vibration and random vibration tests as well as shock tests will be presented. Furthermore a proposal will be presented to use the fibre injector pair qualification model to build an optical prototype bench. The optical prototype bench is a full-scale model of the flight model. It will be used for development and rehearsal of all the assembly stages of the flight model and will provide an on-ground simulator for investigation as an updated engineering model.

In beer brewing, brewers worldwide strive to obtain product consistency in terms of flavour, colour and foam. Important proteins contributing to beer foam are lipid transfer proteins (LTPs), in particular LTP1 and its lipid-bound isoform LTP1b, which are known to transport lipids in vivo and prevent lipids from destabilising the beer foam. LTP1 and LTP1b were successfully purified using only five purification steps with a high purified protein yield (160 mg LTP1 and LTP1b from 200 g barley). Circular dichroism of LTP1 and LTP1b confirmed that both proteins are highly tolerant to high temperatures (>90 °C) and are pH stable, particularly at a neutral to a more basic pH. Only LTP1 exhibited antiyeast and thermo-stable lytic activity, while LTP1b was inactive, indicating that the fatty acid moiety compromised the antimicrobial activity of LTP1. This lack in antiyeast activity and the positive foam properties of LTP1b would benefit beer fermentation and quality. Copyright © 2014 Elsevier Ltd. All rights reserved.

LlPR-10.2B, a Pathogenesis-related class 10 (PR-10) protein from yellow lupine (Lupinus luteus) was crystallized in complex with melatonin, an emerging important plant regulator and antioxidant. The structure reveals two molecules of melatonin bound in the internal cavity of the protein, plus a very well-defined electron density near the cavity entrance, corresponding to an unknown ligand molecule comprised of two flat rings, which is most likely a product of melatonin transformation. In a separate LlPR-10.2B co-crystallization experiment with an equimolar mixture of melatonin and trans-zeatin, which is a cytokinin phytohormone well recognized as a PR-10-binding partner, a quaternary 1 : 1 : 1 : 1 complex was formed, in which one of the melatonin-binding sites has been substituted with trans-zeatin, whereas the binding of melatonin at the second binding site and binding of the unknown ligand are undisturbed. This unusual complex, when compared with the previously described PR-10/trans-zeatin complexes and with the emerging structural information about melatonin binding by PR-10 proteins, provides intriguing insights into the role of PR-10 proteins in phytohormone regulation in plants, especially with the involvement of melatonin, and implicates the PR-10 proteins as low-affinity melatonin binders under the conditions of elevated melatonin concentration. Atomic coordinates and processed structure factors corresponding to the final models of the LlPR-10.2B/melatonin and LlPR-10.2B/melatonin + trans-zeatin complexes have been deposited with the Protein Data Bank (PDB) under the accession codes 5MXB and 5MXW.

Plants have developed many mechanisms to protect themselves against most potential microbial pathogens and diseases. Among these mechanisms, pathogenesis-related proteins are produced as part of the active defence to prevent attack. In this study, a full-length cDNA encoding the CsPR10 protein was identified in fresh saffron stigmas (Crocus sativus). The deduced amino acid sequence from the nucleotide sequence of the coding region showed homology with PR10 proteins. The clone expressed as a protein in fusion with a GST tag produced a 47-kDa protein in E. coli. CsPR10 had ribonuclease activity, with features common to class II-type ribonucleases; its specific activity was quantified as 68.8 U·mg(-1) protein, thus falling within the range of most PR10 proteins exhibiting RNase activity. Antifungal activity of CsPR10 was assayed against Verticillium dahliae, Penicillium sp. and Fusarium oxysporum. CsPR10 inhibited only F. oxysporum growth, and antifungal potency was reflected in a IC(50) of 8.3 μm. Expression analysis showed the presence of high transcript levels in anther and tepal tissues, low levels in stigmas and roots, and no signal detected in leaves. This protein seems to be involved in the active defence response through activation of the jasmonic acid pathway. © 2010 German Botanical Society and The Royal Botanical Society of the Netherlands.
Several different manifestations of lunar transient phenomena (LTP) have been reported. These include: (1) brightenings--both sudden and slow, (2) reddish--both bright and dull, (3) bluish--both bright and dull, (4) fairly abrupt dimmings or darkenings, and (5) obscurations, which may be accompanied by any of the other four manifestations. Approximately 200 lunar features exhibiting such anomalies have been reported at least once, but 80% of all observations are found in less than a dozen sites and 60% are found in about one-half dozen sites. An observing program is being conducted for the Association of Lunar and Planetary Observers which is designed to monitor the LTP sites, the seismic epicenter sites and non-LTP comparison sites. It addresses the ''brightenings'' category of observations and is designed to establish normal brightness of each observed feature for all phases of a lunation. It also seeks to establish a quantified ''seeing'' scale. About one-half dozen observers have reported albedo measures (estimated from an albedo scale set up by each observer). The most extensive new data on albedo versus age (phase of Moon) are for the crater Dawes. Several LTP effects have been discerned in Dawes. In addition, seeing estimates, based on the behavior of a star's diffraction disk, provided some unexpected results when disk behavior is compared with other subjective estimates of seeing

Conclusion: Although ginseng PR-10.3 gene is expressed in all organs of 3-wk-old plantlets, its expression is restricted to leaves in mature 2-yr-old ginseng plants. The putative binding property of PgPR-10.3 with Re is intriguing. Further verification of binding affinity with other biologically important molecules in the large hydrophobic cavity of PgPR-10.3 may provide an insight into the biological features of PR-10 proteins.

The dopaminergic modulation of long-term potentiation (LTP) has been studied well, but the mechanism by which dopamine induces LTP (DA-LTP) in CA1 pyramidal neurons is unknown. Here, we report that DA-LTP in basal dendrites is dependent while in apical dendrites it is independent of activation of L-type voltage-gated calcium channels (VDCC).…
We have found that leptin, at physiological concentrations of 10-12 mol/L, facilitates learning and memory and LTP maintenance in Wistar rats. To explore the role of leptin recepors in learning, memory and synaptic plasticity, experiments were carried out using Zucker rats (Z), db/db mice (db), and ob/ob mice(ob). The former two have defects in leptin receptors and the latter cannot produce normal leptin. Unlike the effects observed in normal rats, high or low frequency stimulation of Schaffer collateral-CA1 synapses in hippocampal slices prepared from Z, db and ob animals failed to induce the learning and memory relevant long-term potentiation or depression in CA1 neurons. However, LTP in ob CA1 synapses was facilitated by leptin at 10-12 mol/L concentration. Moreover, the paired-pulse facilitation of CA1 synaptic potentials and intracellularly recorded postsynaptic responses to the neurotransmitters AMPA, NMDA and GABA, applied electrophoretically to the apical dendrites of CA1 neurons, were approximately the same compared to the control lean animals. In addition, unlike the second messenger responses observed in Wistar rats, calmodulin kinase Ⅱ activity in the CA1 area of Z and db animals was not activated after tetanic stimulation of the Schaffer collaterals. It has been shown that all three strains, Z, db and ob display impaired spatial learning and memory when tested in the Morris water maze. The results of these experiments indicate a close relationship between spatial learning and memory, facilitation of LTP, and calmodulin kinase Ⅱ activity.

Long-term potentiation (LTP) of synaptic efficacy is considered a fundamental mechanism of learning and memory. At the cellular level a large body of evidence demonstrated that the major neuromodulatory neurotransmitters dopamine (DA), norepinephrine (NE), and acetylcholine (ACh) influence LTP magnitude. Noninvasive brain stimulation protocols provide the opportunity to study LTP-like plasticity at the systems level of human cortex. Here we applied paired associative stimulation (PAS) to induce LTP-like plasticity in the primary motor cortex of eight healthy subjects. In a double-blind, randomized, placebo-controlled, crossover design, the acute effects of a single oral dose of the neuromodulatory drugs cabergoline (DA agonist), haloperidol (DA antagonist), methylphenidate (indirect NE agonist), prazosine (NE antagonist), tacrine (ACh agonist), and biperiden (ACh antagonist) on PAS-induced LTP-like plasticity were examined. The antagonists haloperidol, prazosine, and biperiden depressed significantly the PAS-induced LTP-like plasticity observed under placebo, whereas the agonists cabergoline, methylphenidate, and tacrine had no effect. Findings demonstrate that antagonists in major neuromodulatory neurotransmitter systems suppress LTP-like plasticity at the systems level of human cortex, in accord with evidence of their modulating action of LTP at the cellular level. This provides further supportive evidence for the known detrimental effects of these drugs on LTP-dependent mechanisms such as learning and memory.

A novel protein (IWF5) comprising 92 amino acids has been purified from the intercellular washing fluid of sugar beet leaves using cation exchange chromatography and reversed phase high performance liquid chromatography. Based on amino acid sequence homology, including the presence of eight...... cysteines at conserved positions, the protein can be classified as a member of the plant family of non-specific lipid transfer proteins (nsLTPs). The protein is 47% identical to IWF1, an antifungal nsLTP previously isolated from leaves of sugar beet. A potential site for N-linked glycosylation present...

The interferometer of the LISA technology package (LTP) on SMART-2 is needed to verify the performance of the gravitational sensors by monitoring the distance between two test masses with a noise level of 10 pm Hz -1/2 between 3 mHz and 30 mHz. It must continuously track the motion of the test mass distance while that distance changes by many μm with a speed of up to 20 μm s -1 , without losing track of the sign of the motion and without exerting any influence on the test masses that might lead to a motion above that level. As a result of a detailed comparison study, a heterodyne Mach-Zehnder interferometer was selected as the baseline for the SMART-2 mission. Its design and expected performance are described in this paper

Putrescine and spermidine increase the transformation efficiency of Vitis vinifera L. cv. Thompson seedless. Accumulation of VpPR10.1 in transgenic V. vinifera Thompson seedless, likely increases its resistance to downy mildew. A more efficient method is described for facilitating Agrobacterium-mediated transformation of Vitis vinifera L. cv. Thompson Seedless somatic embryogenesis using polyamines (PAs). The efficacies of putrescine, spermidine and spermine are identified at a range of concentrations (10 µM, 100 µM and 1 mM) added to the culture medium during somatic embryo growth. Putrescine (PUT) and spermidine (SPD) promote the recovery of proembryonic masses (PEM) and the development of somatic embryos (SE) after co-cultivation. Judging from the importance of the time-frame in genetic transformation, PAs added at the co-cultivation stage have a stronger effect than delayed selection treatments, which are superior to antibiotic treatments in the selection stage. Best embryogenic responses are with 1 mM PUT and 100 µM SPD added to the co-culture medium. Using the above method, a pathogenesis-related gene (VpPR10.1) from Chinese wild Vitis pseudoreticulata was transferred into Thompson Seedless for functional evaluation. The transgenic line, confirmed by western blot analysis, was inoculated with Plasmopara viticola to test for downy mildew resistance. Based on observed restrictions of hyphal growth and increases in H 2 O 2 accumulation in the transgenic plants, the accumulation of VpPR10.1 likely enhanced the transgenic plants resistance to downy mildew.

Long-term potentiation (LTP) is the principal candidate synaptic mechanism underlying learning and memory, and has been studied extensively at the cellular and molecular level in laboratory animals. Inquiry into the functional significance of LTP has been hindered by the absence of a human model as, until recently, LTP has only been directly demonstrated in humans in isolated cortical tissue obtained from patients undergoing surgery, where it displays properties identical to those seen in non-human preparations. In this brief review, we describe the results of paradigms recently developed in our laboratory for inducing LTP-like changes in visual-, and auditory-evoked potentials. We describe how rapid, repetitive presentation of sensory stimuli leads to a persistent enhancement of components of sensory-evoked potential in normal humans. Experiments to date, investigating the locus, stimulus specificity, and NMDA receptor dependence of these LTP-like changes suggest that they have the essential characteristics of LTP seen in experimental animals. The ability to elicit LTP from non-surgical patients will provide a human model system allowing the detailed examination of synaptic plasticity in normal subjects and may have future clinical applications in the assessment of cognitive disorders.

Wnt signaling is involved in hippocampal development and synaptogenesis. Numerous recent studies have been focused on the role of Wnt ligands in the regulation of synaptic plasticity. Inhibitors and activators of canonical Wnt signaling were demonstrated to decrease or increase, respectively, in vitro long-term potentiation (LTP) maintenance in hippocampal slices (Chen et al. in J Biol Chem 281:11910-11916, 2006; Vargas et al. in J Neurosci 34:2191-2202, 2014, Vargas et al. in Exp Neurol 264:14-25, 2015). Using lentiviral approach to down- and up-regulate the canonical Wnt signaling, we explored whether Wnt/β-catenin signaling is critical for the in vivo LTP. Chronic suppression of Wnt signaling induced an impairment of in vivo LTP expression 14 days after lentiviral suspension injection, while overexpression of Wnt3 was associated with a transient enhancement of in vivo LTP magnitude. Both effects were related to the early phase LTP and did not affect LTP maintenance. A loss-of-function study demonstrated decreased initial paired pulse facilitation ratio, β-catenin, and phGSK-3β levels. A gain-of-function study revealed not only an increase in PSD-95, β-catenin, and Cyclin D1 protein levels, but also a reduced phGSK-3β level and enhanced GSK-3β kinase activity. These results suggest a presynaptic dysfunction predominantly underlying LTP impairment while postsynaptic modifications are primarily involved in transient LTP amplification. This study is the first demonstration of the involvement of Wnt/β-catenin signaling in synaptic plasticity regulation in an in vivo LTP model.
Full Text Available Calcium-calmodulin/dependent protein kinase II (CaMKII plays an essential role in LTP induction, but since it has the capacity to remain persistently activated even after the decay of external stimuli it has been proposed that it can also be necessary for LTP maintenance and therefore for memory persistence. It has been shown that basolateral amygdaloid nucleus (Bla stimulation induces long-term potentiation (LTP in the insular cortex (IC, a neocortical region implicated in the acquisition and retention of conditioned taste aversion (CTA. Our previous studies have demonstrated that induction of LTP in the Bla-IC pathway before CTA training increased the retention of this task. Although it is known that IC-LTP induction and CTA consolidation share similar molecular mechanisms, little is known about the molecular actors that underlie their maintenance. The purpose of the present study was to evaluate the role of CaMKII in the maintenance of in vivo Bla-IC LTP as well as in the persistence of CTA long-term memory (LTM. Our results show that acute microinfusion of myr-CaMKIINtide, a selective inhibitor of CaMKII, in the IC of adult rats during the late-phase of in vivo Bla-IC LTP blocked its maintenance. Moreover, the intracortical inhibition of CaMKII 24 h after CTA acquisition impairs CTA-LTM persistence. Together these results indicate that CaMKII is a central key component for the maintenance of neocortical synaptic plasticity as well as for persistence of CTA-LTM.

Lipid transfer protein (LTP) is a widely cross-reacting plant pan-allergen. Adverse reactions to Rosaceae, tree nuts, peanut, beer, maize, mustard, asparagus, grapes, mulberry, cabbage, dates, orange, fig, kiwi, lupine, fennel, celery, tomato, eggplant, lettuce, chestnut and pineapple have been recorded. To detect vegetable foods to be regarded as safe for LTP-allergic patients. Tolerance/intolerance to a large spectrum of vegetable foods other than Rosaceae, tree nuts and peanut was assessed by interview in 49 subjects monosensitized to LTP and in three distinct groups of controls monosensitized to Bet v 1 (n = 24) or Bet v 2 (n = 18), or sensitized to both LTP and birch pollen (n = 16), all with a history of vegetable food allergy. Patients and controls underwent skin prick test (SPT) with a large spectrum of vegetable foods. The absence of IgE reactivity to foods that were negative in both clinical history and SPT was confirmed by immunoblot analysis and their clinical tolerance was finally assessed by open oral challenge (50 g per food). All patients reported tolerance and showed negative SPT to carrot, potato, banana and melon; these foods scored positive in SPT and elicited clinical symptoms in a significant proportion of patients from all three control groups. All patients tolerated these four foods on oral challenge. Immunoblot analysis confirmed the lack of IgE reactivity to these foods by LTP-allergic patients. Carrot, potato, banana and melon seem safe for LTP-allergic patients. This finding may be helpful for a better management of allergy to LTP.

Learning interference occurs when learning something new causes forgetting of an older memory (retrograde interference) or when learning a new task disrupts learning of a second subsequent task (anterograde interference). This phenomenon, described in cognitive, sensory, and motor domains, limits our ability to learn multiple tasks in close succession. It has been suggested that the source of interference is competition of neural resources, although the neuronal mechanisms are unknown. Learning induces long-term potentiation (LTP), which can ultimately limit the ability to induce further LTP, a phenomenon known as occlusion. In humans we quantified the magnitude of occlusion of anodal transcranial direct current stimulation-induced increased excitability after learning a skill task as an index of the amount of LTP-like plasticity used. We found that retention of a newly acquired skill, as reflected by performance in the second day of practice, is proportional to the magnitude of occlusion. Moreover, the degree of behavioral interference was correlated with the magnitude of occlusion. Individuals with larger occlusion after learning the first skill were (1) more resilient to retrograde interference and (2) experienced larger anterograde interference when training a second task, as expressed by decreased performance of the learned skill in the second day of practice. This effect was not observed if sufficient time elapsed between training the two skills and LTP-like occlusion was not present. These findings suggest competition of LTP-like plasticity is a factor that limits the ability to remember multiple tasks trained in close succession.
Chance events led me to a lifelong career in scientific research. They paved the way for being the first to see long-term potentiation of synaptic efficiency (LTP) in Per Andersen's laboratory in Oslo in 1966. Here I describe my way to this discovery and the experiments with Tim Bliss in 1968-1969 that led to Bliss and Lømo, 1973. Surprisingly, we later failed to reproduce these results. I discuss possible reasons for this failure, which made us both leave LTP research, in my case for good, in Tim's case for several years. After 30 years of work in a different field, I renewed my interest in the hippocampus and LTP in the early 2000s and published, for the first time, results that I had obtained 40 years earlier. Here I present my take on how interest in and research on LTP evolved after the early years. This includes a discussion of the functions of hippocampus as seen in those early days, the case of patient H.M., Donald Hebb's place in the story, the search for 'memory molecules' such as PKMζ, and the primary site for LTP expression (pre- and/or post-synaptic?). Throughout, I reflect on my life in science, how science is done and what drives it. The reflections are quite personal and I admit to mixed feelings about broadcasting them. © 2017 Scandinavian Physiological Society. Published by John Wiley & Sons Ltd.
Full Text Available Hippocampal synaptic plasticity and learning are strongly regulated by metabotropic glutamate receptors (mGluRs and particularly by mGluR5. Here, we investigated the mechanisms underlying mGluR5-modulation of these phenomena. Prolonged pharmacological blockade of mGluR5 with MPEP produced a profound impairment of spatial memory. Effects were associated with 1 a reduction of mGluR1a-expression in the dentate gyrus; 2 impaired dentate gyrus LTP; 3 enhanced CA1-LTP and 4 suppressed theta (5-10 Hz and gamma (30-100 Hz oscillations in the dentate gyrus. Allosteric potentiation of mGluR1 after mGluR5 blockade significantly ameliorated dentate gyrus LTP, as well as suppression of gamma oscillatory activity. CA3-lesioning prevented MPEP effects on CA1-LTP, suggesting that plasticity levels in CA1 are driven by mGluR5-dependent synaptic and network activity in the dentate gyrus. These data support the hypothesis that prolonged mGluR5-inactivation causes altered hippocampal LTP levels and network activity, which is mediated in part by impaired mGluR1-expression in the dentate gyrus. The consequence is impairment of long-term learning.

(TLE). However, our previous studies show that recombinant adeno-associated viral (rAAV)-NPY treatment in naive rats attenuates long-term potentiation (LTP) and transiently impairs hippocampal learning process, indicating that negative effect on memory function could be a potential side effect of NPY...... is significantly attenuated in vitro. Importantly, transgene NPY overexpression has no effect on short-term synaptic plasticity, and does not further compromise LTP in kindled animals. These data suggest that epileptic seizure-induced impairment of memory function in the hippocampus may not be further affected...... injected with rAAV-NPY, we show that rapid kindling-induced hippocampal seizures in vivo are effectively suppressed as compared to rAAV-empty injected (control) rats. Six to nine weeks later, basal synaptic transmission and short-term synaptic plasticity are unchanged after rapid kindling, while LTP...

The history of activity of a given neuron has been proposed to bidirectionally influence its future response to synaptic inputs. In particular, induction of synaptic plasticity expressions such as long-term potentiation (LTP) and long-term depression (LTD) modifies the performance of several behavioral tasks. Our previous studies in the insular cortex (IC), a neocortical region that has been related to acquisition and retention of conditioned taste aversion (CTA), have demonstrated that induction of LTP in the basolateral amygdaloid nucleus (Bla)-IC pathway before CTA training enhances the retention of this task. In addition, we reported that CTA training triggers a persistent impairment in the ability to induce in vivo LTP in the IC. The aim of the present study was to investigate whether LTD can be induced in the Bla-IC projection in vivo, as well as, whether the extinction of CTA is bidirectionally modified by previous synaptic plasticity induction in this pathway. Thus, rats received 900 train pulses (five 250μs pulses at 250Hz) delivered at 1Hz in the Bla-IC projection in order to induce LTD or 10 trains of 100Hz/1s with an intertrain interval of 20s in order to induce LTP. Seven days after surgery, rats were trained in the CTA task including the extinction trials. Our results show that the Bla-IC pathway is able to express in vivo LTD in an N-Methyl-D-aspartate (NMDA) receptor-dependent manner. Induction of LTD in the Bla-IC projection previous to CTA training facilitates the extinction of this task. Conversely, LTP induction enhances CTA retention. The present results show the bidirectional modulation of CTA extinction in response to IC-LTP and LTD, providing evidence of the homeostatic adaptation of taste learning.

Low-temperature plasma (LTP) permits direct ambient ionization and mass analysis of samples in their native environment with minimal or no prior preparation. LTP utilizes dielectric barrier discharges (DBDs) to create a low power plasma which is guided by gas flow onto the sample from which analytes are desorbed and ionized. In this study, the potential of LTP-MS for the detection of pesticide residues in food is demonstrated. Thirteen multi-class agricultural chemicals were studied (ametryn, amitraz, atrazine, buprofezin, DEET, diphenylamine, ethoxyquin, imazalil, isofenphos-methyl, isoproturon, malathion, parathion-ethyl and terbuthylazine). To evaluate the potential of the proposed approach, LTP-MS experiments were performed directly on fruit peels as well as on fruit/vegetable extracts. Most of the agrochemicals examined displayed remarkable sensitivity in the positive ion mode, giving limits of detection (LOD) for the direct measurement in the low picogram range. Tandem mass spectrometry (MS/MS) was used to confirm identification of selected pesticides by using for these experiments spiked fruit/vegetable extracts (QuEChERS, a standard sample treatment protocol) at levels as low as 1 pg, absolute, for some of the analytes. Comparisons of the data obtained by direct LTP-MS were made with the slower but more accurate conventional LC-MS/MS procedure. Herbicides spiked in aqueous solutions were detectable at LODs as low as 0.5 microg L(-1) without the need for any sample preparation. The results demonstrate that ambient LTP-MS can be applied for the detection and confirmation of traces of agrochemicals in actual market-purchased produce and in natural water samples. Quantitative analysis was also performed in a few selected cases and displayed a relatively high degree of linearity over four orders of magnitude.

Full Text Available The glutamatergic N-methyl-D-aspartate receptor (NMDAR is critically involved in many forms of hippocampus-dependent memory that may be enabled by synaptic plasticity. Behavioral studies with NMDAR antagonists and NMDAR subunit (GluN2 mutants revealed distinct contributions from GluN2A- and GluN2B-containing NMDARs to rapidly and slowly acquired memory performance. Furthermore, studies of synaptic plasticity, in genetically modified mice in vitro, suggest that GluN2A and GluN2B may contribute in different ways to the induction and longevity of synaptic plasticity. In contrast to the hippocampal slice preparation, in behaving mice, the afferent frequencies that induce synaptic plasticity are very restricted and specific. In fact, it is the stimulus pattern, and not variations in afferent frequency that determine the longevity of long-term potentiation (LTP. Here, we explored the contribution of GluN2A and GluN2B to LTP of differing magnitudes and persistencies in freely behaving mice. We applied differing high-frequency stimulation (HFS patterns at 100 Hz to the hippocampal CA1 region, to induce NMDAR-dependent LTP in wild-type (WT mice, that endured for 24h (late (L-LTP. In GluN2A-KO mice, E-LTP (HFS, 50 pulses was significantly reduced in magnitude and duration, whereas LTP (HFS, 2 x 50 pulses and L-LTP (HFS, 4 x 50 pulses were unaffected compared to responses in WT animals. By contrast, pharmacological antagonism of GluN2B in WT had no effect on E-LTP but significantly prevented LTP. E- LTP and LTP were significantly impaired by GluN2B antagonism in GluN2A-KO mice. These data indicate that the pattern of afferent stimulation is decisive for the recruitment of distinct GluN2A and GluN2B signaling pathways that in turn determine the persistency of hippocampal LTP. Whereas brief bursts of patterned stimulation preferentially recruit GluN2A and lead to weak and short-lived forms of LTP, prolonged, more intense, afferent activation recruits GluN2B

Genetic variants in the human ortholog of acid-sensing ion channel-1a subunit (ASIC1a) gene are associated with panic disorder and amygdala dysfunction. Both fear learning and activity-induced long-term potentiation (LTP) of cortico-basolateral amygdala (BLA) synapses are impaired in ASIC1a-null mice, suggesting a critical role of ASICs in fear memory formation. In this study, we found that ASICs were differentially expressed within the amygdala neuronal population, and the extent of LTP at various glutamatergic synapses correlated with the level of ASIC expression in postsynaptic neurons. Importantly, selective deletion of ASIC1a in GABAergic cells, including amygdala output neurons, eliminated LTP in these cells and reduced fear learning to the same extent as that found when ASIC1a was selectively abolished in BLA glutamatergic neurons. Thus, fear learning requires ASIC-dependent LTP at multiple amygdala synapses, including both cortico-BLA input synapses and intra-amygdala synapses on output neurons.

In auditory fear conditioning, experimental subjects learn to associate an auditory conditioned stimulus (CS) with an aversive unconditioned stimulus. With sufficient training, animals fear conditioned to an auditory CS show fear response to the CS, but not to irrelevant auditory stimuli. Although long-term potentiation (LTP) in the lateral amygdala (LA) plays an essential role in auditory fear conditioning, it is unknown whether LTP is induced selectively in the neural pathways conveying specific CS information to the LA in discriminative fear learning. Here, we show that postsynaptically expressed LTP is induced selectively in the CS-specific auditory pathways to the LA in a mouse model of auditory discriminative fear conditioning. Moreover, optogenetically induced depotentiation of the CS-specific auditory pathways to the LA suppressed conditioned fear responses to the CS. Our results suggest that input-specific LTP in the LA contributes to fear memory specificity, enabling adaptive fear responses only to the relevant sensory cue. VIDEO ABSTRACT.

It is widely accepted that the synaptic dysfunction and synapse loss contribute to the cognitive deficits of vascular dementia (VD) patients. We have previously reported that acupuncture improved cognitive function in rats with VD. However, the mechanisms involved in acupuncture improving cognitive ability remain to be elucidated. The present study aims to investigate the pathways and molecules involved in the neuroprotective effect of acupuncture. We assessed the effects of acupuncture on hippocampal long-term potentiation (LTP), the most prominent cellular model of memory formation. Acupuncture enhanced LTP and norepinephrine (NE) levels in the hippocampus. Inhibition of the β-adrenergic receptor (AR), but not the α-AR, was able to block the effects of acupuncture on hippocampal LTP. Furthermore, inhibition of β1-AR, not β2-AR, abolished the enhanced LTP induced by acupuncture. The expression analysis revealed a significant upregulation of β1-AR and unchanged β2-AR with acupuncture, which supported the above findings. Specifically, increased β1-ARs in the dentate gyrus were expressed on neurons exclusively. Taken together, the present data supports a beneficial role of acupuncture in synaptic plasticity challenged with VD. A likely mechanism is the increase of NE and activation of β1-AR in the hippocampus.
Full Text Available Methamphetamine (METH is an addictive psychostimulant whose societal impact is on the rise. Emerging evidence suggests that psychostimulants alter synaptic plasticity in the brain--which may partly account for their adverse effects. While it is known that METH increases the extracellular concentration of monoamines dopamine, serotonin, and norepinephrine, it is not clear how METH alters glutamatergic transmission. Within this context, the aim of the present study was to investigate the effects of acute and systemic METH on basal synaptic transmission and long-term potentiation (LTP; an activity-induced increase in synaptic efficacy in CA1 sub-field in the hippocampus. Both the acute ex vivo application of METH to hippocampal slices and systemic administration of METH decreased LTP. Interestingly, the acute ex vivo application of METH at a concentration of 30 or 60 microM increased baseline synaptic transmission as well as decreased LTP. Pretreatment with eticlopride (D2-like receptor antagonist did not alter the effects of METH on synaptic transmission or LTP. In contrast, pretreatment with D1/D5 dopamine receptor antagonist SCH23390 or 5-HT1A receptor antagonist NAN-190 abrogated the effect of METH on synaptic transmission. Furthermore, METH did not increase baseline synaptic transmission in D1 dopamine receptor haploinsufficient mice. Our findings suggest that METH affects excitatory synaptic transmission via activation of dopamine and serotonin receptor systems in the hippocampus. This modulation may contribute to synaptic maladaption induced by METH addiction and/or METH-mediated cognitive dysfunction.

Full Text Available Abstract A consensus has famously yet to emerge on the locus and mechanisms underlying the expression of the canonical NMDA receptor-dependent form of LTP. An objective assessment of the evidence leads us to conclude that both presynaptic and postsynaptic expression mechanisms contribute to this type of synaptic plasticity.

Background: Long-Term Potentiation (LTP) is recognised as a core neuronal process underlying long-term memory. However, a direct relationship between LTP and human memory performance is yet to be demonstrated. The first aim of the current study was thus to assess the relationship between LTP and human long-term memory performance. With this also comes an opportunity to explore factors thought to mediate the relationship between LTP and long-term memory, and to gain additional insight into var...

Hippocampus-dependent memory is modulated by the amygdala. However, it is unknown whether intracellular Zn 2+ signaling in the amygdala is involved in hippocampus-dependent memory. On the basis of the evidence that intracellular Zn 2+ signaling in dentate granule cells (DGC) is necessary for object recognition memory via LTP at medial perforant pathway (PP)-DGC synapses, the present study examined whether intracellular Zn 2+ signaling in the amygdala influences object recognition memory via modulation of LTP at medial PP-DGC synapses. When ZnAF-2DA (100 μM, 2 μl) was injected into the basolateral amygdala (BLA), intracellular ZnAF-2 locally chelated intracellular Zn 2+ in the amygdala. Recognition memory was affected when training of object recognition test was performed 20 min after ZnAF-2DA injection into the BLA. Twenty minutes after injection of ZnAF-2DA into the BLA, LTP induction at medial PP-DGC synapses was attenuated, while LTP induction at PP-BLA synapses was potentiated and LTP induction at BLA-DGC synapses was attenuated. These results suggest that intracellular Zn 2+ signaling in the BLA is involved in BLA-associated LTP and modulates LTP at medial PP-DGC synapses, followed by modulation of object recognition memory.

An in vitro orthodromic stimulation technique was used to examine the effects of lindane and long-term potentiation (LTP) inducing stimuli, alone or in combination, on the excitatory afferent terminal of CA1 pyramidal cells and on recurrent collateral evoked inhibition using the rat hippocampal slice model. Hippocampal slices of 400 microns thickness were perfused with oxygenated artificial cerebrospinal fluid. Stimulation of Schaffer collateral/commissural fibers produced extracellular excitatory postsynaptic potential (EPSP) and/or populations spike (PS) responses recorded from electrodes in the CA1 region. A paired-pulse technique was used to measure gamma-aminobutyric acid (GABAA)-mediated recurrent inhibition before and after treatments. After both lindane and LTP, larger PS amplitudes for a given stimulus intensity were seen. The resulting leftward shift in the curve of the PS amplitude versus stimulus intensity was larger after LTP than after 25 microM lindane. Both lindane and LTP treatments reduced PS thresholds and reduced or eliminated recurrent inhibition as measured by paired-pulse stimulation at the 15 msec interval. The reduction of recurrent inhibition after both treatments was more pronounced at lower stimulus intensities. When LTP stimuli were applied after lindane exposure a further large shift to the left was seen in the PS amplitude versus stimulus intensity curve. A smaller shift to the left was seen in the PS amplitude versus stimulus intensity curve only at the higher stimuli when lindane exposure occurred after LTP. Only at low stimulus intensities were further argumentations seen in PS amplitudes when the LTP stimuli was followed by a second LTP stimuli. Previous exposure to 25 microM lindane stimuli does not block the development of a further robust LTP in this in vitro model.

The stability analysis of grid-connected converters have attracted increasing attentions, due to the oscillations arising in wind power plants, micro-grids, and other emerging power electronics based power systems. The modeling tool of converters thus becomes essential to faithfully reveal...... oscillations without any hidden regions. This paper presents a detailed comparison of two linearized modeling methods, which are, respectively, developed in the Linear Time-Invariant (LTI) and the Linear Time-Periodic (LTP) frameworks. The LTP model can consider the effect of frequency-coupling dynamics, which...... are occurred by the time-varying behavior, while the conventional LTI model can not capture this behavior. The advantages and limits of two models are then illustrated with examples. The compared results are verified in the frequency domain and time domain as well....

The influx of extracellular Zn(2+) into dentate granule cells is nonessential for dentate gyrus long-term potentiation (LTP) and the physiological significance of extracellular Zn(2+) dynamics is unknown in the dentate gyrus. Excess increase in extracellular Zn(2+) in the hippocampal CA1, which is induced with excitation of zincergic neurons, induces memory deficit via excess influx of Zn(2+) into CA1 pyramidal cells. In the present study, it was examined whether extracellular Zn(2+) induces object recognition memory deficit via excess influx of Zn(2+) into dentate granule cells. KCl (100 mM, 2 µl) was locally injected into the dentate gyrus. The increase in intracellular Zn(2+) in dentate granule cells induced with high K(+) was blocked by co-injection of CaEDTA and CNQX, an extracellular Zn(2+) chelator and an AMPA receptor antagonist, respectively, suggesting that high K(+) increases the influx of Zn(2+) into dentate granule cells via AMPA receptor activation. Dentate gyrus LTP induction was attenuated 1 h after KCl injection into the dentate gyrus and also attenuated when KCl was injected 5 min after the induction. Memory deficit was induced when training of object recognition test was performed 1 h after KCl injection into the dentate gyrus and also induced when KCl was injected 5 min after the training. High K(+)-induced impairments of LTP and memory were rescued by co-injection of CaEDTA. These results indicate that excess influx of Zn(2+) into dentate granule cells via AMPA receptor activation affects object recognition memory via attenuated LTP induction. Even in the dentate gyrus where is scarcely innervated by zincergic neurons, it is likely that extracellular Zn(2+) homeostasis is strictly regulated for cognition. Copyright © 2015 Elsevier Ltd.

LysoPAF acetyltransferase (lysoPAF-AT) and PAF-synthesizing phosphocholinetransferase (PAF-PCT) are the two enzymes which catalyze the final reactions for the synthesis of PAF. Their activities, assayed in the homogenate of rat brain stem slices and under their optimal conditions, increased 5 min after high frequency stimulation of vestibular afferents, inducing LTP in the medial vestibular nuclei. The activity of phosphatidylcholine-synthesizing phosphocholinetransferase, was not affected. Sixty minutes from the induction of LTP, PAF-PCT activity, but not that of lysoPAF-AT, was still significantly higher with respect to 5 min test stimulated control. We used AP-5 to verify whether this increase was strictly dependent upon LTP induction, which requires NMDA receptor activation. In AP-5 treated slices, lysoPAF-acetyltransferase and PAF-synthesizing phosphocholinetransferase activities increased, but they were reduced after high frequency stimulation under AP-5. In conclusion, we have demonstrated that the activities of PAF-synthesizing enzymes are activated soon after the induction of LTP and that this effect is linked to the activation of NMDA-receptors. We suggest that the enzyme activation by AP-5, preventing LTP, might be due to glutamate enhancement but, in neurons showing LTP and under normal conditions, the activation of potentiation mechanisms is critical for the enhancement of enzyme activities.

The idea that maintained LTP and memory are lost by either increase in intracellular Zn 2+ in dentate granule cells or increase in intracellular Ca 2+ was examined to clarify significance of the increases induced by excess synapse excitation. Both maintained LTP and space memory were impaired by injection of high K + into the dentate gyrus, but rescued by co-injection of CaEDTA, which blocked high K + -induced increase in intracellular Zn 2+ but not high K + -induced increase in intracellular Ca 2+ . High K + -induced disturbances of LTP and intracellular Zn 2+ are rescued by co-injection of 6-cyano-7-nitroquinoxakine-2,3-dione, an α-amino-3-hydroxy-5-methyl-4-isoxazolepropionate (AMPA) receptor antagonist, but not by co-injection of blockers of NMDA receptors, metabotropic glutamate receptors, and voltage-dependent calcium channels. Furthermore, AMPA impaired maintained LTP and the impairment was also rescued by co-injection of CaEDTA, which blocked increase in intracellular Zn 2+ , but not increase in intracellular Ca 2+ . NMDA and glucocorticoid, which induced Zn 2+ release from the internal stores, did not impair maintained LTP. The present study indicates that increase in Zn 2+ influx into dentate granule cells through AMPA receptors loses maintained LTP and memory. Regulation of Zn 2+ influx into dentate granule cells is more critical for not only memory acquisition but also memory retention than that of Ca 2+ influx.

In rodents, many exogenous and endogenous cannabinoids, such as anandamide (AEA) and 2-arachidonyl glycerol (2-AG), have been shown to play an important role in certain hippocampal memory processes. However, the mechanisms by which endogenous AEA regulate this processes are not well understood. Here the effects of AEA on long-term potentiation (LTP), hippocampal-dependent learning and memory tasks, pERK1/2, pCaMKIV, and pCREB signaling events in both cannabinoid receptor type 1 (CB1R) wild-type (WT) and knockout (KO) mice were assessed following administration of URB597, an inhibitor of the fatty acid amide hydrolase (FAAH). Acute administration of URB597 enhanced AEA levels without affecting the levels of 2-AG or CB1R in the hippocampus and neocortex as compared to vehicle. In hippocampal slices, URB597 impaired LTP in CB1R WT but not in KO littermates. URB597 impaired object recognition, spontaneous alternation and spatial memory in the Y-maze test in CB1R WT mice but not in KO mice. Furthermore, URB597 enhanced ERK phosphorylation in WT without affecting total ERK levels in WT or KO mice. URB597 impaired CaMKIV and CREB phosphorylation in WT but not in KO mice. CB1R KO mice have a lower pCaMKIV/CaMKIV ratio and higher pCREB/CREB ratio as compared to WT littermates. Our results indicate that pharmacologically elevated AEA impair LTP, learning and memory and inhibit CaMKIV and CREB phosphorylation, via the activation of CB1Rs. Collectively, these findings also suggest that pharmacological elevation of AEA beyond normal concentrations is also detrimental for the underlying physiological responses. © 2014 Wiley Periodicals, Inc.

Memory involves the storage of information at synapses by an LTP-like process. This information storage is synapse specific and can endure for years despite the turnover of all synaptic proteins. There must, therefore, be special principles that underlie the stability of LTP. Recent experimental results suggest that LTP is maintained by the complex of CaMKII with the NMDAR. Here we consider the specifics of the CaMKII/NMDAR molecular switch, with the goal of understanding the biochemical principles that underlie stable information storage by synapses. Consideration of a variety of experimental results suggests that multiple principles are involved. One switch requirement is to prevent spontaneous transitions from the off to the on state. The highly cooperative nature of CaMKII autophosphorylation by Ca(2+) (Hill coefficient of 8) and the fact that formation of the CaMKII/NMDAR complex requires release of CaMKII from actin are mechanisms that stabilize the off state. The stability of the on state depends critically on intersubunit autophosphorylation, a process that restores any loss of pT286 due to phosphatase activity. Intersubunit autophosphorylation is also important in explaining why on state stability is not compromised by protein turnover. Recent evidence suggests that turnover occurs by subunit exchange. Thus, stability could be achieved if a newly inserted unphosphorylated subunit was autophosphorylated by a neighboring subunit. Based on other recent work, we posit a novel mechanism that enhances the stability of the on state by protection of pT286 from phosphatases. We posit that the binding of the NMNDAR to CaMKII forces pT286 into the catalytic site of a neighboring subunit, thereby protecting pT286 from phosphatases. A final principle concerns the role of structural changes. The binding of CaMKII to the NMDAR may act as a tag to organize the binding of further proteins that produce the synapse enlargement that underlies late LTP. We argue that these
Full Text Available LTP-like plasticity measured by visual evoked potentials (VEP can be induced in the intact human brain by presenting checkerboard reversals. Also associated with LTP-like plasticity, around two third of participants respond to transcranial magnetic stimulation with a paired-associate stimulation (PAS protocol with a potentiation of their motor evoked potentials. LTP-like processes are also required for verbal and motor learning tasks. We compared effect sizes, responder rates and intercorrelations as well as the potential influence of attention between these four assessments in a group of 37 young and healthy volunteers. We observed a potentiation effect of the N75 and P100 VEP component which positively correlated with plasticity induced by PAS. Subjects with a better subjective alertness were more likely to show PAS and VEP potentiation. No correlation was found between the other assessments. Effect sizes and responder rates of VEP potentiation were higher compared to PAS. Our results indicate a high variability of LTP-like effects and no evidence for a system-specific nature. As a consequence, studies wishing to assess individual levels of LTP-like plasticity should employ a combination of multiple assessments.

Physiological significance of synaptic Zn 2+ signaling was examined at perforant pathway-CA1 pyramidal cell synapses. In vivo long-term potentiation (LTP) at perforant pathway-CA1 pyramidal cell synapses was induced using a recording electrode attached to a microdialysis probe and the recording region was locally perfused with artificial cerebrospinal fluid (ACSF) via the microdialysis probe. Perforant pathway LTP was not attenuated under perfusion with CaEDTA (10 mM), an extracellular Zn 2+ chelator, but attenuated under perfusion with ZnAF-2DA (50 μM), an intracellular Zn 2+ chelator, suggesting that intracellular Zn 2+ signaling is required for perforant pathway LTP. Even in rat brain slices bathed in CaEDTA in ACSF, intracellular Zn 2+ level, which was measured with intracellular ZnAF-2, was increased in the stratum lacunosum-moleculare where perforant pathway-CA1 pyramidal cell synapses were contained after tetanic stimulation. These results suggest that intracellular Zn 2+ signaling, which originates in internal stores/proteins, is involved in LTP at perforant pathway-CA1 pyramidal cell synapses. Because the influx of extracellular Zn 2+ , which originates in presynaptic Zn 2+ release, is involved in LTP at Schaffer collateral-CA1 pyramidal cell synapses, synapse-dependent Zn 2+ dynamics may be involved in plasticity of postsynaptic CA1 pyramidal cells. © 2017 Wiley Periodicals, Inc.

The next generation of synchrotrons and free electron laser facilities requires x-ray optical systems with extremely high performance, generally of diffraction limited quality. Fabrication and use of such optics requires adequate, highly accurate metrology and dedicated instrumentation. Previously, we suggested ways to improve the performance of the Long Trace Profiler (LTP), a slope measuring instrument widely used to characterize x-ray optics at long spatial wavelengths. The main way is use of a CCD detector and corresponding technique for calibration of photo-response non-uniformity [J. L. Kirschman, et al., Proceedings of SPIE 6704, 67040J (2007)]. The present work focuses on the performance and characteristics of the upgraded LTP-II at the ALS Optical Metrology Laboratory. This includes a review of the overall aspects of the design, control system, the movement and measurement regimes for the stage, and analysis of the performance by a slope measurement of a highly curved super-quality substrate with less than 0.3 microradian (rms)slope variation

In this study in patients with Parkinson's disease (PD), off and on dopaminergic therapy, with and without L-dopa-induced dyskinesias (LIDs), we tested intermittent theta-burst stimulation (iTBS), a technique currently used for non-invasively inducing long-term potentiation (LTP)-like plasticity in primary motor cortex (M1). The study group comprised 20 PD patients on and off dopaminergic therapy (11 patients without and 9 patients with LIDs), and 14 age-matched healthy subjects. Patients had mild-to-moderate PD, and no additional neuropsychiatric disorders. We clinically evaluated patients using the Unified Parkinson's Disease Rating Scale (UPDRS) and the Unified Dyskinesia Rating Scale (UDysRS). The left M1 was conditioned with iTBS at 80% active motor threshold intensity. Twenty motor evoked potentials (MEPs) were recorded from right first interosseous muscle before and at 5, 15 and 30 min after iTBS. Between-group analysis of variance (ANOVA) testing healthy subjects versus patients with and without LIDs, on and off therapy showed a significant interaction between factors "Group" and "Time". After iTBS, MEP amplitudes in healthy subjects increased significantly at 5, 15 and 30 min (piTBS fails to increase MEP responses. This finding suggests lack of iTBS-induced LTP-like plasticity in M1 in PD regardless of patients' clinical features. Copyright Â© 2010 Elsevier Inc. All rights reserved.

Accumulating evidence indicates that homeostatic plasticity mechanisms dynamically adjust synaptic strength to promote stability that is crucial for memory storage. Our previous studies have shown that prior training in conditioned taste aversion (CTA) prevents the subsequent induction of long-term potentiation (LTP) in the projection from the basolateral nucleus of the amygdala (Bla) to the insular cortex (IC) in vivo. We have also reported that induction of LTP in the Bla-IC pathway modifies the CTA extinction. Memoryextinction involves the formation of a new associativememorythat inhibits a previously conditioned association. The aim of the present study was to analyze the effect of CTA extinction on the ability to induce subsequent LTP in the Bla-IC projection in vivo. Thus, 48 h after CTA extinction animals received high frequency stimulation in order to induce IC-LTP. Our results show that extinction training allows the induction but not the maintenance of IC-LTP. In addition, with the purpose of exploring part of the mechanisms involved in this process and since a body of evidence suggests that protein phosphatase calcineurin (CaN) is involved in the extinction of some behavioral tasks, we analyzed the participation of this phosphatase. The present results show that extinction training increases the CaN expression in the IC, as well as that the inhibition of this phosphatase reverts the effects of the CTA-extinction on the IC-LTP. These findings reveal that CTA extinction promotes a homeostatic regulation of subsequent IC synaptic plasticity maintenance through increases in CaN levels. Copyright © 2018 Elsevier Inc.

The fungus Cochliobolus sativus is the main pathogen of common root rot, a serious soil-borne disease of wheat (Triticum aestivum L.). The fungus Fusarium graminearum is the primary pathogen of Fusarium head blight, a devastating disease of wheat worldwide. In this study, the wheat lipid transfer protein gene, TaLTP5, was cloned and evaluated for its ability to suppress disease development in transgenic wheat. TaLTP5 expression was induced after C. sativus infection. The TaLTP5 expression vector, pA25-TaLTP5, was constructed and bombarded into Chinese wheat variety Yangmai 18. Six TaLTP5 transgenic wheat lines were established and characterized. PCR and Southern blot analyses indicated that the introduced TaLTP5 gene was integrated into the genomes of six transgenic wheat lines by distinct patterns, and heritable. RT-PCR and real-time quantitative RT-PCR revealed that the TaLTP5 gene was over-expressed in the transgenic wheat lines compared to segregants lacking the transgene and wild-type wheat plants. Following challenge with C. sativus or F. graminearum, all six transgenic lines overexpressing TaLTP5 exhibited significantly enhanced resistance to both common root rot and Fusarium head blight compared to the untransformed wheat Yangmai 18.

The dentate gyrus (DG) of the hippocampus is critical for spatial memory and is also thought to be involved in the formation of drug-related associative memory. Here, we attempt to test an aspect of the Gateway Hypothesis, by studying the effect of consecutive exposure to nicotine and cocaine on long-term synaptic potentiation (LTP) in the DG. We…

Capsaicin has been shown to modulate synaptic plasticity in various brain regions including the amygdala. Whereas in the lateral amygdala the modulatory effect of capsaicin on long-term potentiation (LA-LTP) is mediated by TRPV1 channels, we have recently shown that capsaicin-induced enhancement of long term depression (LA-LTD) is mediated by…

Long-term potentiation (LTP) is typically studied using either continuous high-frequency stimulation or theta burst stimulation. Previous studies emphasized the physiological relevance of theta frequency; however, synchronized hippocampal activity occurs over a broader frequency range. We therefore tested burst stimulation at intervals from 100…

There is no evidence on the precise role of synaptic Zn2+ signaling on the retention and recall of recognition memory. On the basis of the findings that intracellular Zn2+ signaling in the dentate gyrus is required for object recognition, short-term memory, the present study deals with the effect of spatiotemporally blocking Zn2+ signaling in the dentate gyrus after LTP induction and learning. Three-day-maintained LTP was impaired 1 day after injection of clioquinol into the dentate gyrus, which transiently reduced intracellular Zn2+ signaling in the dentate gyrus. The irreversible impairment was rescued not only by co-injection of ZnCl2 , which ameliorated the loss of Zn2+ signaling, but also by pre-injection of Jasplakinolide, a stabilizer of F-actin, prior to clioquinol injection. Simultaneously, 3-day-old space recognition memory was impaired 1 day after injection of clioquinol into the dentate gyrus, but not by pre-injection of Jasplakinolide. Jasplakinolide also rescued both impairments of 3-day-maintained LTP and 3-day-old memory after injection of ZnAF-2DA into the dentate gyrus, which blocked intracellular Zn2+ signaling in the dentate gyrus. The present paper indicates that the blockade and/or loss of intracellular Zn2+ signaling in the dentate gyrus coincidently impair maintained LTP and recognition memory. The mechanism maintaining LTP via intracellular Zn2+ signaling in dentate granule cells, which may be involved in the formation of F-actin, may retain space recognition memory. © 2015 Wiley Periodicals, Inc.

Acetylcholine facilitates long-term potentiation (LTP) and long-term depression (LTD), substrates of learning, memory, and sensory processing, in which acetylcholine also plays a crucial role. Ca(2+) ions serve as a canonical regulator of LTP/LTD but little is known about the effect of acetylcholine on intracellular Ca(2+) dynamics. Here, we investigated dendritic Ca(2+) dynamics evoked by synaptic stimulation and the resulting LTP/LTD in layer 2/3 pyramidal neurons of the rat visual cortex. Under muscarinic stimulation, single-shock electrical stimulation (SES) inducing ∼20 mV EPSP, applied via a glass electrode located ∼10 μm from the basal dendrite, evoked NMDA receptor-dependent fast Ca(2+) transients and the subsequent Ca(2+) release from the inositol 1,4,5-trisphosphate (IP(3))-sensitive stores. These secondary dendritic Ca(2+) transients were highly localized within 10 μm from the center (SD = 5.0 μm). The dendritic release of Ca(2+) was a prerequisite for input-specific muscarinic LTP (LTPm). Without the secondary Ca(2+) release, only muscarinic LTD (LTDm) was induced. D(-)-2-amino-5-phosphopentanoic acid and intracellular heparin blocked LTPm as well as dendritic Ca(2+) release. A single burst consisting of 3 EPSPs with weak stimulus intensities instead of the SES also induced secondary Ca(2+) release and LTPm. LTPm and LTDm were protein synthesis-dependent. Furthermore, LTPm was confined to specific dendritic compartments and not inducible in distal apical dendrites. Thus, cholinergic activation facilitated selectively compartment-specific induction of late-phase LTP through IP(3)-dependent Ca(2+) release.

Glucocorticoid-glutamatergic interactions have been proposed as a potential model to explain stress-mediated impairment of cognition. However, it is unknown whether glucocorticoid-zincergic interactions are involved in this impairment. Histochemically reactive zinc (Zn(2+)) is co-released with glutamate from zincergic neurons. In the present study, involvement of synaptic Zn(2+) in stress-induced attenuation of CA1 LTP was examined in hippocampal slices from young rats after exposure to tail suspension stress for 30s, which significantly increased serum corticosterone. Stress-induced attenuation of CA1 LTP was ameliorated by administration of clioquinol, a membrane permeable zinc chelator, to rats prior to exposure to stress, implying that the reduction of synaptic Zn(2+) by clioquinol participates in this amelioration. To pursue the involvement of corticosterone-mediated Zn(2+) signal in the attenuated CA1 LTP by stress, dynamics of synaptic Zn(2+) was checked in hippocampal slices exposed to corticosterone. Corticosterone increased extracellular Zn(2+) levels measured with ZnAF-2 dose-dependently, as well as the intracellular Ca(2+) levels measured with calcium orange AM, suggesting that corticosterone excites zincergic neurons in the hippocampus and increases Zn(2+) release from the neuron terminals. Intracellular Zn(2+) levels measured with ZnAF-2DA were also increased dose-dependently, but not in the coexistence of CaEDTA, a membrane-impermeable zinc chelator, suggesting that intracellular Zn(2+) levels is increased by the influx of extracellular Zn(2+). Furthermore, corticosterone-induced attenuation of CA1 LTP was abolished in the coexistence of CaEDTA. The present study suggests that corticosterone-mediated increase in postsynaptic Zn(2+) signal in the cytosolic compartment is involved in the attenuation of CA1 LTP after exposure to acute stress.

Full Text Available The persistence and input specificity of long-term potentiation (LTP make it attractive as a mechanism of information storage. In its initial phase, both in vivo and in vitro studies have shown that LTP is associated with increased membrane localization of AMPA receptor subunits, but the molecular basis of LTP maintenance over the long-term is still unclear. We have previously shown that expression of AMPA and NMDA receptor subunits is elevated in whole homogenates prepared from dentate gyrus 48 h after LTP induction in vivo. In the present study, we utilized laser microdissection (LMD techniques to determine whether AMPA and NMDA receptor upregulation occurs specifically in the stimulated regions of the dentate gyrus dendritic arbor. Receptor proteins GluN1, GluA1 and GluA2, as well as postsynaptic density protein of 95 kDa and tubulin were detected by Western blot analysis in microdissected samples. Gradients of expression were observed for GluN1 and GluA2, decreasing from the inner to the outer zones of the molecular layer, and were independent of LTP. When induced at medial perforant path synapses, LTP was associated with an apparent specific redistribution of GluA1 and GluN1 to the middle molecular layer that contains these synapses. These data indicate that glutamate receptor proteins are delivered specifically to dendritic regions possessing LTP-expressing synapses, and that these changes are preserved for at least 48 h.

R-type calcium channels in postsynaptic spines signal through functional calcium microdomains to regulate a calcium-calmodulin sensitive potassium channel that in turn regulates postsynaptic hippocampal LTP. Here we ask whether R-type calcium channels in presynaptic terminals also signal through calcium microdomains to control presynaptic LTP. We focus on presynaptic LTP at parallel fiber to Purkinje cell synapses in the cerebellum (PF-LTP), which is mediated by calcium/calmodulin-stimulated adenylyl cyclases. Although most presynaptic calcium influx is through N-type and P/Q-type calcium channels, blocking these channels does not disrupt PF-LTP, but blocking R-type calcium channels does. Moreover, global calcium signaling cannot account for the calcium dependence of PF-LTP because R-type channels contribute modestly to overall calcium entry. These findings indicate that within presynaptic terminals, R-type calcium channels produce calcium microdomains that evoke presynaptic LTP at moderate frequencies that do not greatly increase global calcium levels,.

The first in-situ distortion profile measurement of a high heat load mirror by use of the penta-prism LTP is presented. A maximum height distortion of 0.47 micron in tangential direction over a length of 180 mm was measured for an internally water-cooled mirror of a undulator beam line at ELETTRA while exposed to a total emitted power of 600 W (undulator gap 30 mm and current 180 mA). The experiment has an accuracy and repeatability of 0.04 micron. The test schematic and the test equipment are presented. Two measuring methods to scan a penta-prism being installed either outside or inside the vacuum chamber are introduced. Advantages and some possible applications of adopting the penta-prism LTP to make the in-situ profile test are explained

Memory is lost by the increased influx of extracellular Zn 2+ into neurons. It is possible that intracellular Zn 2+ dynamics is modified even at non-zincergic medial perforant pathway-dentate granule cell synapses along with aging and that vulnerability to the modification is linked to age-related cognitive decline. To examine these possibilities, vulnerability of long-term potentiation (LTP) maintenance, which underlies memory retention, to modification of synaptic Zn 2+ dynamics was compared between young and aged rats. The influx of extracellular Zn 2+ into dentate granule cells was increased in aged rats after injection of high K + into the dentate gyrus, but not in young rats. This increase impaired maintained LTP in aged rats. However, the impairment was rescued by co-injection of CaEDTA, an extracellular Zn 2+ chelator, or CNQX, an AMPA receptor antagonist, which suppressed the Zn 2+ influx. Maintained LTP was also impaired in aged rats after injection of ZnAF-2DA into the dentate gyrus that chelates intracellular Zn 2+ , but not in young rats. Interestingly, the capacity of chelating intracellular Zn 2+ with intracellular ZnAF-2 was almost lost in the aged dentate gyrus 2 h after injection of ZnAF-2DA into the dentate gyrus, suggesting that intracellular Zn 2+ -buffering is weakened in the aged dentate gyrus, compared to the young dentate gyrus. In the dentate gyrus of aged rats, maintained LTP is more vulnerable to modification of intracellular Zn 2+ dynamics than in young rats, probably due to weakened intracellular Zn 2+ -buffering.
Full Text Available Microtubule associated protein tau (MAPT is involved in the pathogenesis of Alzheimer's disease and many forms of frontotemporal dementia (FTD. We recently reported that Aβ-mediated inhibition of hippocampal long-term potentiation (LTP in mice requires tau. Here, we asked whether expression of human MAPT can restore Aβ-mediated inhibition on a mouse Tau−/− background and whether human tau with an FTD-causing mutation (N296H can interfere with Aβ-mediated inhibition of LTP. We used transgenic mouse lines each expressing the full human MAPT locus using bacterial artificial chromosome technology. These lines expressed all six human tau protein isoforms on a Tau−/− background. We found that the human wild-type MAPT H1 locus was able to restore Aβ42-mediated impairment of LTP. In contrast, Aβ42 did not reduce LTP in slices in two independently generated transgenic lines expressing tau protein with the mutation N296H associated with frontotemporal dementia (FTD. Basal phosphorylation of tau measured as the ratio of AT8/Tau5 immunoreactivity was significantly reduced in N296H mutant hippocampal slices. Our data show that human MAPT is able to restore Aβ42-mediated inhibition of LTP in Tau−/− mice. These results provide further evidence that tau protein is central to Aβ-induced LTP impairment and provide a valuable tool for further analysis of the links between Aβ, human tau and impairment of synaptic function.

The GPRM (Grabbing, Position and Release Mechanism) is part of the Caging Mechanism (CM) and its electrical control unit (CCU) of the LISA Technology Package (LTP) on board ESA's LISA Pathfinder Spacecraft (LPF). The GPRM was only tested at sub-assembly level (one half on the mechanism) but never in assembled configuration on system level with the flight electronics (CCU). The developing company (RUAG Space, CH) was contracted with these limited activities.The GPRM EQM was successfully tested in 2008 and the two flight models were delivered in 2009. Due to design evolution of the CM, the flight GPRMs could not be tested in assembled configuration directly after their delivery. These GPRM system tests needed to be implemented in the upgraded CM design. In addition an alternative integration and alignment approach was developed taking advantage of the experience to date, which also resulted in an optimised schedule.As a consequence of the above mentioned starting point and the evolution of Caging Mechanism, the interface to the CM, an alternative alignment concept and verification approach of the GPRM needed to be developed and implemented by MAGNA Steyr Aerospace in close cooperation with all involved parties. The TV and functional test set-up was refurbished and pre-tests were performed such that the requirements could be verified. Vibration testing of the GPRM in its assembled and aligned configuration was different due to the new test and verification approach. New FEM models for the GPRM vibration test needed to be established and verified.Handling and operating the flight hardware, establishment of new alignment approaches and upgrade of test equipment for the new approach were the major challenges in this verification programme.This paper presents the alignment and testing activities of the GPRM together with its control electronics - the CCU.
Full Text Available Long-term potentiation (LTP and long-term depression (LTD are widely accepted to be synaptic mechanisms involved in learning and memory. It remains uncertain, however, which particular activity rules are utilized by hippocampal neurons to induce LTP and LTD in behaving animals. Recent experiments in the dentate gyrus of freely moving rats revealed an unexpected pattern of LTP and LTD from high-frequency perforant path stimulation. While 400 Hz theta-burst stimulation (400-TBS and 400 Hz delta-burst stimulation (400-DBS elicited substantial LTP of the tetanized medial path input and, concurrently, LTD of the non-tetanized lateral path input, 100 Hz theta-burst stimulation (100-TBS, a normally efficient LTP protocol for in vitro preparations produced only weak LTP and concurrent LTD. Here we show in a biophysically realistic compartmental granule cell model that this pattern of results can be accounted for by a voltage-based spike-timing-dependent plasticity (STDP rule combined with a relatively fast Bienenstock-Cooper-Munro (BCM-like homeostatic metaplasticity rule, all on a background of ongoing spontaneous activity in the input fibers. Our results suggest that, at least for dentate granule cells, the interplay of STDP-BCM plasticity rules and ongoing pre- and postsynaptic background activity determines not only the degree of input-specific LTP elicited by various plasticity-inducing protocols, but also the degree of associated LTD in neighboring non-tetanized inputs, as generated by the ongoing constitutive activity at these synapses.
Full Text Available Abstract Background Nuclear factor kappa B (NF-κB is a transcription factor typically expressed with two specific subunits (p50, p65. Investigators have reported that NF-κB is activated during the induction of in vitro long term potentiation (LTP, a paradigm of synaptic plasticity and correlate of memory, suggesting that NF-κB may be necessary for some aspects of memory encoding. Furthermore, NF-κB has been implicated as a potential requirement in behavioral tests of memory. Unfortunately, very little work has been done to explore the effects of deleting specific NF-κB subunits on memory. Studies have shown that NF-κB p50 subunit deletion (p50−/− leads to memory deficits, however some recent studies suggest the contrary where p50−/− mice show enhanced memory in the Morris water maze (MWM. To more critically explore the role of the NF-κB p50 subunit in synaptic plasticity and memory, we assessed long term spatial memory in vivo using the MWM, and synaptic plasticity in vitro utilizing high frequency stimuli capable of eliciting LTP in slices from the hippocampus of NF-κB p50−/− versus their controls (p50+/+. Results We found that the lack of the NF-κB p50 subunit led to significant decreases in late LTP and in selective but significant alterations in MWM tests (i.e., some improvements during acquisition, but deficits during retention. Conclusions These results support the hypothesis that the NF-κ p50 subunit is required in long term spatial memory in the hippocampus.

Pomegranate allergy is associated with sensitization to non-specific lipid transfer proteins (nsLTPs). Our aim was to identify and characterize the non-specific nsLTPs expressed in pomegranate at the molecular level and to study their allergenic properties in terms of immunoglobulin E (IgE)-binding and cross-reactivity with peach nsLTP (Pru p 3). A non-equilibrium two-dimensional (2-D) electrophoretic approach based on acid-urea PAGE and sodium dodecyl sulfate PAGE was set up to separate pomegranate nsLTPs. Their immunoreactivity was tested by immunoblotting carried out with anti-Pru p 3 polyclonal antibodies and sera from pomegranate-allergic patients. For final identification, pomegranate nsLTPs were purified by chromatography and subjected to trypsin digestion and mass spectrometry (MS) analysis. For this purpose, the sequences obtained by cDNA cloning of three pomegranate nsLTPs were integrated in the database that was subsequently searched for MS data interpretation. Four nsLTPs were identified by 2-D immunoblotting. The detected proteins showed different IgE-binding capacity and partial cross-reactivity with Pru p 3. cDNA cloning and MS analyses led to the identification of three nsLTP isoforms with 66-68% amino acid sequence identity named Pun g 1.0101, Pun g 1.0201 and Pun g 1.0301. By 2-D electrophoresis, we could separate different nsLTP isoforms possessing different IgE-binding properties, which might reflect peculiar allergenic potencies. The contribution of Pru p 3 to prime sensitization is not central as in other plant nsLTPs. © 2014 S. Karger AG, Basel.
Full Text Available Fragile X syndrome is a common inherited form of mental retardation caused by the lack of fragile X mental retardation protein (FMRP because of Fmr1 gene silencing. Serotonin (5-HT is significantly increased in the null mutants of Drosophila Fmr1, and elevated 5-HT brain levels result in cognitive and behavioral deficits in human patients. The serotonin type 2A receptor (5-HT2AR is highly expressed in the cerebral cortex; it acts on pyramidal cells and GABAergic interneurons to modulate cortical functions. 5-HT2AR and FMRP both regulate synaptic plasticity. Therefore, the lack of FMRP may affect serotoninergic activity. In this study, we determined the involvement of FMRP in the 5-HT modulation of synaptic potentiation with the use of primary cortical neuron culture and brain slice recording. Pharmacological inhibition of 5-HT2AR by R-96544 or ketanserin facilitated long-term potentiation (LTP in the anterior cingulate cortex (ACC of WT mice. The prefrontal LTP induction was dependent on the activation of NMDARs and elevation of postsynaptic Ca(2+ concentrations. By contrast, inhibition of 5-HT2AR could not restore the induction of LTP in the ACC of Fmr1 knock-out mice. Furthermore, 5-HT2AR inhibition induced AMPA receptor GluR1 subtype surface insertion in the cultured ACC neurons of Fmr1 WT mice, however, GluR1 surface insertion by inhibition of 5-HT2AR was impaired in the neurons of Fmr1KO mice. These findings suggested that FMRP was involved in serotonin receptor signaling and contributed in GluR1 surface expression induced by 5-HT2AR inactivation.
Full Text Available The precise role of neural plasticity under pathological conditions remains not well understood. It appears to be well accepted, however, that changes in the ability of neurons to express plasticity accompany neurological diseases. Here, we discuss recent experimental evidence, which suggests that synaptic plasticity induced by a pathological stimulus, i.e., ischemic long-term-potentiation (iLTP of excitatory synapses, could play an important role for post-stroke recovery by influencing the post-lesional reorganization of surviving neuronal networks.
The effect of acute swim stress and training in the water maze on hippocampal synaptic activity as well as plasticity in the dentate gyrus of freely moving rats: revisiting swim-induced LTP reinforcement.
Tabassum, Heena; Frey, Julietta U
Hippocampal long-term potentiation (LTP) is a cellular model of learning and memory. An early form of LTP (E-LTP) can be reinforced into its late form (L-LTP) by various behavioral interactions within a specific time window ("behavioral LTP-reinforcement"). Depending on the type and procedure used, various studies have shown that stress differentially affects synaptic plasticity. Under low stress, such as novelty detection or mild foot shocks, E-LTP can be transformed into L-LTP in the rat dentate gyrus (DG). A reinforcing effect of a 2-min swim, however, has only been shown in (Korz and Frey (2003) J Neurosci 23:7281-7287; Korz and Frey (2005) J Neurosci 25:7393-7400; Ahmed et al. (2006) J Neurosci 26:3951-3958; Sajikumar et al., (2007) J Physiol 584.2:389-400) so far. We have reinvestigated these studies using the same as well as an improved recording technique which allowed the recording of field excitatory postsynaptic potentials (fEPSP) and the population spike amplitude (PSA) at their places of generation in freely moving rats. We show that acute swim stress led to a long-term depression (LTD) in baseline values of PSA and partially fEPSP. In contrast to earlier studies a LTP-reinforcement by swimming could never be reproduced. Our results indicate that 2-min swim stress influenced synaptic potentials as well as E-LTP negatively.

Transcranial Alternating Current Stimulation (tACS) consists in delivering electric current to the brain using an oscillatory pattern that may entrain the rhythmic activity of cortical neurons. When delivered at gamma frequency, tACS modulates motor performance and GABA-A-ergic interneuron activity. Since interneuronal discharges play a crucial role in brain plasticity phenomena, here we co-stimulated the primary motor cortex (M1) in healthy subjects by means of tACS during intermittent theta-burst stimulation (iTBS), a transcranial magnetic stimulation paradigm known to induce long-term potentiation (LTP)-like plasticity. We measured and compared motor evoked potentials before and after gamma, beta and sham tACS-iTBS. While we delivered gamma-tACS, we also measured short-interval intracortical inhibition (SICI) to detect any changes in GABA-A-ergic neurotransmission. Gamma, but not beta and sham tACS, significantly boosted and prolonged the iTBS-induced after-effects. Interestingly, the extent of the gamma tACS-iTBS after-effects correlated directly with SICI changes. Overall, our findings point to a link between gamma oscillations, interneuronal GABA-A-ergic activity and LTP-like plasticity in the human M1. Gamma tACS-iTBS co-stimulation might represent a new strategy to enhance and prolong responses to plasticity-inducing protocols, thereby lending itself to future applications in the neurorehabilitation setting.

An increased influx of extracellular Zn 2+ into neurons is a cause of cognitive decline. The influx of extracellular Zn 2+ into dentate granule cells was compared between young and middle-aged rats because of vulnerability of the dentate gyrus to aging. The influx of extracellular Zn 2+ into dentate granule cells was increased in middle-aged rats after injection of AMPA and high K + into the dentate gyrus, but not in young rats. Simultaneously, high K + -induced attenuation of LTP was observed in middle-aged rats, but not in young rats. The attenuation was rescued by co-injection of CaEDTA, an extracellular Zn 2+ chelator. Intracellular Zn 2+ in dentate granule cells was also increased in middle-aged slices with high K + , in which the increase in extracellular Zn 2+ was the same as young slices with high K + , suggesting that ability of extracellular Zn 2+ influx into dentate granule cells is greater in middle-aged rats. Furthermore, extracellular zinc concentration in the hippocampus was increased age-dependently. The present study suggests that the influx of extracellular Zn 2+ into dentate granule cells is more readily increased in middle-aged rats and that its increase is a cause of age-related attenuation of LTP in the dentate gyrus.

Activation of Beta-adrenergic receptors (Beta-ARs) enhances hippocampal memory consolidation and long-term potentiation (LTP), a likely mechanism for memory storage. One signaling pathway linked to Beta-AR activation is the cAMP-PKA pathway. PKA is critical for the consolidation of hippocampal long-term memory and for the expression of some forms…
Chronic developmental lead (Pb) exposure increases the threshold and enhances decay of long-term potentiation (LTP) in the dentate gyrus of the hippocampal formation. MK-801 and other antagonists of the N-methyl-D-aspartate (NMDA) glutamate receptor subtype impair induction of LT...

Decades of brain research have identified various parallel loops linking the hippocampus with neocortical areas, enabling the acquisition of spatial and episodic memories. Especially the hippocampal trisynaptic circuit [entorhinal cortex layer II → dentate gyrus (DG) → cornu ammonis (CA)-3 → CA1] was studied in great detail because of its seemingly simple connectivity and characteristic structures that are experimentally well accessible. While numerous researchers focused on functional aspects, obtained from a limited number of cells in distinct hippocampal subregions, little is known about the neuronal network dynamics which drive information across multiple synapses for subsequent long-term storage. Fast voltage-sensitive dye imaging in vitro allows real-time recording of activity patterns in large/meso-scale neuronal networks with high spatial resolution. In this way, we recently found that entorhinal theta-frequency input to the DG most effectively passes filter mechanisms of the trisynaptic circuit network, generating activity waves which propagate across the entire DG-CA axis. These "trisynaptic circuit waves" involve high-frequency firing of CA3 pyramidal neurons, leading to a rapid induction of classical NMDA receptor-dependent long-term potentiation (LTP) at CA3-CA1 synapses (CA1 LTP). CA1 LTP has been substantially evidenced to be essential for some forms of explicit learning in mammals. Here, we review data with particular reference to whole network-level approaches, illustrating how activity propagation can take place within the trisynaptic circuit to drive formation of CA1 LTP.

Synthetic amyloid-β protein (Aβ) oligomers bind with high affinity to cellular prion protein (PrP(C)), but the role of this interaction in mediating the disruption of synaptic plasticity by such soluble Aβ in vitro is controversial. Here we report that intracerebroventricular injection of Aβ-containing aqueous extracts of Alzheimer\\'s disease (AD) brain robustly inhibits long-term potentiation (LTP) without significantly affecting baseline excitatory synaptic transmission in the rat hippocampus in vivo. Moreover, the disruption of LTP was abrogated by immunodepletion of Aβ. Importantly, intracerebroventricular administration of antigen-binding antibody fragment D13, directed to a putative Aβ-binding site on PrP(C), prevented the inhibition of LTP by AD brain-derived Aβ. In contrast, R1, a Fab directed to the C terminus of PrP(C), a region not implicated in binding of Aβ, did not significantly affect the Aβ-mediated inhibition of LTP. These data support the pathophysiological significance of SDS-stable Aβ dimer and the role of PrP(C) in mediating synaptic plasticity disruption by soluble Aβ.

Nr4a nuclear receptors contribute to long-term memory formation and are required for long-term memory enhancement by a class of broad-acting drugs known as histone deacetylase (HDAC) inhibitors. Understanding the molecular mechanisms that regulate these genes and identifying ways to increase their activity may provide novel therapeutic approaches for ameliorating cognitive dysfunction. In the present study, we find that Nr4a gene expression after learning requires the cAMP-response element binding (CREB) interaction domain of the histone acetyltransferase CREB-binding protein (CBP). These gene expression deficits emerge at a time after learning marked by promoter histone acetylation in wild-type mice. Further, mutation of the CREB-CBP interaction domain reduces Nr4a promoter acetylation after learning. As memory enhancement by HDAC inhibitors requires CREB-CBP interaction and Nr4a gene function, these data support the notion that the balance of histone acetylation at the Nr4a promoters is critical for memory formation. NR4A ligands have recently been described, but the effect of these drugs on synaptic plasticity or memory has not been investigated. We find that the 'C-DIM' NR4A ligands, para-phenyl substituted di-indolylmethane compounds, enhance long-term contextual fear memory and increase the duration of long-term potentiation (LTP), a form of hippocampal synaptic plasticity. LTP enhancement by these drugs is eliminated in mice expressing a dominant negative form of NR4A and attenuated in mice with mutation of the CREB-CBP interaction domain. These data define the molecular connection between histone acetylation and Nr4a gene expression after learning. In addition, they suggest that NR4A-activating C-DIM compounds may serve as a potent and selective means to enhance memory and synaptic plasticity.

Costello syndrome (CS) is a rare congenital disorder due to a G12S amino acid substitution in HRAS protoncogene. Previous studies have shown that Paired Associative Stimulation (PAS), a repetitive brain stimulation protocol inducing motor cortex plasticity by coupling peripheral nerve stimulation with brain stimulation, leads to an extremely pronounced motor cortex excitability increase in CS patients. Intermittent Theta Burst Stimulation (iTBS) represents a protocol able to induce motor cortex plasticity by trains of stimuli at 50 Hz. In healthy subjects PAS and iTBS produce similar after-effects in motor cortex excitability. Experimental models showed that HRAS-dependent signalling pathways differently affect LTP induced by different patterns of repetitive synaptic stimulation. We aimed to compare iTBS-induced after-effects on motor cortex excitability with those produced by PAS in CS patients and to observe whether HRAS mutation differentially affects two different forms of neuromodulation protocols. We evaluated in vivo after-effects induced by PAS and iTBS applied over the right motor cortex in 4 CS patients and in 21 healthy age-matched controls. Our findings confirmed HRAS-dependent extremely pronounced PAS-induced after-effects and showed for the first time that iTBS induces no change in MEP amplitude in CS patients whereas both protocols lead to an increase of about 50% in controls. CS patients are characterized by an impairment of iTBS-related LTP-like phenomena besides enhanced PAS-induced after-effects, suggesting that HRAS-dependent signalling pathways have a differential influence on PAS- and iTBS-induced plasticity in humans.

In this paper, under different illuminations and random noises, focusing on the local texture feature's defects of a face image that cannot be completely described because the threshold of local ternary pattern (LTP) cannot be calculated adaptively, a local three-value model of improved adaptive local ternary pattern (IALTP) is proposed. Firstly, the difference function between the center pixel and the neighborhood pixel weight is established to obtain the statistical characteristics of the central pixel and the neighborhood pixel. Secondly, the adaptively gradient descent iterative function is established to calculate the difference coefficient which is defined to be the threshold of the IALTP operator. Finally, the mean and standard deviation of the pixel weight of the local region are used as the coding mode of IALTP. In order to reflect the overall properties of the face and reduce the dimension of features, the two-directional two-dimensional PCA ((2D)2PCA) is adopted. The IALTP is used to extract local texture features of eyes and mouth area. After combining the global features and local features, the fusion features (IALTP+) are obtained. The experimental results on the Extended Yale B and AR standard face databases indicate that under different illuminations and random noises, the algorithm proposed in this paper is more robust than others, and the feature's dimension is smaller. The shortest running time reaches 0.329 6 s, and the highest recognition rate reaches 97.39%.

Full Text Available NMDA receptor subunits change during development and their synaptic expression is modified rapidly after synaptic plasticity induction in hippocampal slices. However, there is scarce information on subunits expression after synaptic plasticity induction or memory acquisition, particularly in adults. GluN1, GluN2A and GluN2B NMDA receptor subunits were assessed by western blot in 1 adult rats that had explored an open field (OF for 5 minutes, a time sufficient to induce habituation, 2 mature rat hippocampal neuron cultures depolarized by KCl and 3 hippocampal slices from adult rats where long term potentiation (LTP was induced by theta-burst stimulation (TBS. GluN1 and GluN2A, though not GluN2B, were significantly higher 70 minutes--but not 30 minutes--after a 5 minutes session in an OF. GluN1 and GluN2A total immunofluorescence and puncta in neurites increased in cultures, as evaluated 70 minutes after KCl stimulation. Similar changes were found in hippocampal slices 70 minutes after LTP induction. To start to explore underlying mechanisms, hippocampal slices were treated either with cycloheximide (a translation inhibitor or actinomycin D (a transcription inhibitor during electrophysiological assays. It was corroborated that translation was necessary for LTP induction and expression. The rise in GluN1 depends on transcription and translation, while the increase in GluN2A appears to mainly depend on translation, though a contribution of some remaining transcriptional activity during actinomycin D treatment could not be rouled out. LTP effective induction was required for the subunits to increase. Although in the three models same subunits suffered modifications in the same direction, within an apparently similar temporal course, further investigation is required to reveal if they are related processes and to find out whether they are causally related with synaptic plasticity, learning and memory.
Full Text Available Ethanol (EtOH–induced impairment of long-term potentiation (LTP in the rat hippocampus is prevented by the 5α-reductase inhibitor finasteride, suggesting that this effect of EtOH is dependent on the increased local release of neurosteroids such as 3α,5α-THP that promote GABA–mediated transmission. Given that social isolation (SI in rodents is associated with altered plasma and brain levels of such neurosteroids as well as with an enhanced neurosteroidogenic action of EtOH, we examined whether the inhibitory effect of EtOH on LTP at CA3-CA1 hippocampal excitatory synapses is altered in C57BL/6J mice subjected to SI for 6 weeks in comparison with group-housed (GH animals. Extracellular recording of fEPSPs as well as patch-clamp analysis were performed in hippocampal slices prepared from both SI and GH mice. Consistent with previous observations, recording of fEPSPs revealed that the extent of LTP induced in the CA1 region of SI mice was significantly reduced compared with that in GH animals. EtOH (40 mM inhibited LTP in slices from SI mice but not in those from GH mice, and this effect of EtOH was abolished by co-application of 1 µM finasteride. Current-clamp analysis of CA1 pyramidal neurons revealed a decrease in action potential frequency and an increase in the intensity of injected current required to evoke the first action potential in SI mice compared with GH mice, indicative of a decrease in neuronal excitability associated with SI. Together, our data suggest that SI results in reduced levels of neuronal excitability and synaptic plasticity in the hippocampus. Furthermore, the increased sensitivity to the neurosteroidogenic effect of EtOH associated with SI likely accounts for the greater inhibitory effect of EtOH on LTP in SI mice. The increase in EtOH sensitivity induced by SI may be important for the changes in the effects of EtOH on anxiety and on learning and memory associated with the prolonged stress attributable to social

Full Text Available Antidepressant drugs are usually administered for long time for the treatment of major depressive disorder. However, they are also prescribed in several additional psychiatric conditions as well as during long term maintenance treatments. Antidepressants induce adaptive changes in several forebrain structures which include modifications at glutamatergic synapses. We recently found that repetitive administration of the selective serotonin reuptake inhibitor fluoxetine to naϊve adult male rats induced an increase of mature, mushroom-type dendritic spines in several forebrain regions. This was associated with an increase of GluA2-containing α-amino-3-hydroxy-5-methylisoxazole-4-propionate receptors (AMPA-Rs in telencephalic postsynaptic densities. To unravel the functional significance of such a synaptic re-arrangement, we focused on glutamate neurotransmission in the hippocampus. We evaluated the effect of four weeks of treatment with 0.7 mg/kg of fluoxetine on long-term potentiation (LTP and long-term depression (LTD in the Schaffer collateral-CA1 synapses and the perforant path-CA1 synapses. Recordings in hippocampal slices revealed profound deficits in LTP and LTD at Schaffer collateral-CA1 synapses associated to increased spine density and enhanced presence of mushroom-type spines, as revealed by Golgi staining. However, the same treatment had neither an effect on spine morphology, nor on LTP and LTD at perforant path-CA1 synapses. Cobalt staining experiments revealed decreased AMPA-R Ca2+ permeability in the stratum radiatum together with increased GluA2-containing, Ca2+-impermeable AMPA-Rs. Therefore, 4 weeks of fluoxetine treatment promoted structural and functional adaptations in CA1 neurons in a pathway-specific manner that were selectively associated with impairment of activity-dependent plasticity at Schaffer collateral-CA1 synapses.

Estrogen, in addition to its genomic effects, triggers rapid synaptic changes in hippocampus and cortex. Here we summarize evidence that the acute actions of the steroid arise from actin signaling cascades centrally involved in long-term potentiation (LTP). A 10-min infusion of E2 reversibly increased fast EPSPs and promoted theta burst-induced LTP within adult hippocampal slices. The latter effect reflected a lowered threshold and an elevated ceiling for the potentiation effect. E2's actions on transmission and plasticity were completely blocked by latrunculin, a toxin that prevents actin polymerization. E2 also caused a reversible increase in spine concentrations of filamentous (F-) actin and markedly enhanced polymerization caused by theta burst stimulation (TBS). Estrogen activated the small GTPase RhoA, but not the related GTPase Rac, and phosphorylated (inactivated) synaptic cofilin, an actin severing protein targeted by RhoA. An inhibitor of RhoA kinase (ROCK) thoroughly suppressed the synaptic effects of E2. Collectively, these results indicate that E2 engages a RhoA >ROCK> cofilin> actin pathway also used by brain-derived neurotrophic factor and adenosine, and therefore belongs to a family of 'synaptic modulators' that regulate plasticity. Finally, we describe evidence that the acute signaling cascade is critical to the depression of LTP produced by ovariectomy.
Full Text Available BDNF signaling contributes to protein-synthesis-dependent synaptic plasticity, but the dynamics of TrkB signaling and mechanisms of translation have not been defined. Here, we show that long-term potentiation (LTP consolidation in the dentate gyrus of live rodents requires sustained (hours BDNF-TrkB signaling. Surprisingly, this sustained activation maintains an otherwise labile signaling pathway from TrkB to MAP-kinase-interacting kinase (MNK. MNK activity promotes eIF4F translation initiation complex formation and protein synthesis in mechanistically distinct early and late stages. In early-stage translation, MNK triggers release of the CYFIP1/FMRP repressor complex from the 5′-mRNA cap. In late-stage translation, MNK regulates the canonical translational repressor 4E-BP2 in a synapse-compartment-specific manner. This late stage is coupled to MNK-dependent enhanced dendritic mRNA translation. We conclude that LTP consolidation in the dentate gyrus is mediated by sustained BDNF signaling to MNK and MNK-dependent regulation of translation in two functionally and mechanistically distinct stages.

The current study examined the coparenting and toddler's interactive styles in family coalitions. According to structural family theory, boundaries between generations are clear in alliances, but disturbed in coalitions: the parents look to the child to regulate their conflictual relationship and the child attempts to meet this need. In a normative sample studied longitudinally during the Lausanne Trilogue Play situation (LTP, N=38), 15 coalition cases were detected. Styles of coparenting and of child's interactions were determined and compared in coalition and alliance cases at 18 months. Findings confirm the structural family model by showing the specific ways in which the coparenting and the toddler's interactive styles are associated in 3 different patterns of coalitions: binding, detouring, and triangulation. They illustrate how the child's triangular capacity, or her ability to simultaneously communicate with both parents, is used to regulate the parents' relationship. They suggest that the LTP observational paradigm is a promising assessment method of early family interactions. They point to the importance of assessing early the child's contribution to family coalitions.
Full Text Available Abstract Background Fragile X syndrome (FXS is caused by the absence of the mRNA-binding protein Fragile X mental retardation protein (FMRP, encoded by the Fmr1 gene. Overactive signaling by group 1 metabotropic glutamate receptor (Grp1 mGluR could contribute to slowed synaptic development and other symptoms of FXS. Our previous study has identified that facilitation of synaptic long-term potentiation (LTP by D1 receptor is impaired in Fmr1 knockout (KO mice. However, the contribution of Grp1 mGluR to the facilitation of synaptic plasticity by D1 receptor stimulation in the prefrontal cortex has been less extensively studied. Results Here we demonstrated that DL-AP3, a Grp1 mGluR antagonist, rescued LTP facilitation by D1 receptor agonist SKF81297 in Fmr1KO mice. Grp1 mGluR inhibition restored the GluR1-subtype AMPA receptors surface insertion by D1 activation in the cultured Fmr1KO neurons. Simultaneous treatment of Grp1 mGluR antagonist with D1 agonist recovered the D1 receptor signaling by reversing the subcellular redistribution of G protein-coupled receptor kinase 2 (GRK2 in the Fmr1KO neurons. Treatment of SKF81297 alone failed to increase the phosphorylation of NR2B-containing N-methyl D-aspartate receptors (NMDARs at Tyr-1472 (p-NR2B-Tyr1472 in the cultures from KO mice. However, simultaneous treatment of DL-AP3 could rescue the level of p-NR2B-Tyr1472 by SKF81297 in the cultures from KO mice. Furthermore, behavioral tests indicated that simultaneous treatment of Grp1 mGluR antagonist with D1 agonist inhibited hyperactivity and improved the learning ability in the Fmr1KO mice. Conclusion The findings demonstrate that mGluR1 inhibition is a useful strategy to recover D1 receptor signaling in the Fmr1KO mice, and combination of Grp1 mGluR antagonist and D1 agonist is a potential drug therapy for the FXS.

Apium graveolens represents a relevant food allergen source linked with severe systemic reactions. We sought to identify an IgE-binding nonspecific lipid transfer protein (nsLTP) in celery tuber. A low molecular weight protein exclusively present in celery tuber was purified and designated Api g 6. The entire protein sequence was obtained by MS and classified as member of the nsLTP2 family. Api g 6 is monomeric in solution with a molecular mass of 6936 Da. The alpha-helical disulfide bond-stabilized structure confers tremendous thermal stability (Tm > 90°C) and high resistance to gastrointestinal digestion. Endolysosomal degradation demonstrated low susceptibility and the presence of a dominant peptide cluster at the C-terminus. Thirty-eight percent of A. graveolens allergic patients demonstrated IgE reactivity to purified natural Api g 6 in ELISA and heat treatment did only partially reduce its allergenic activity. No correlation in IgE binding and limited cross-reactivity was observed with Api g 2 and Art v 3, nsLTP1 from celery stalks and mugwort pollen. Api g 6, a novel nsLTP2 from celery tuber represents the first well-characterized allergen in this protein family. Despite similar structural and physicochemical features as nsLTP1, immunological properties of Api g 6 are distinct which warrants its inclusion in molecule-based diagnosis of A. graveolens allergy. © 2013 WILEY-VCH Verlag GmbH & Co.

The latest studies and practice guidelines for the treatment of adolescent patients with anorexia nervosa agree in pointing out the key role played by parents in determining the young patients' therapeutic possibilities and outcomes. Still family functioning has usually been studied using only self-reported instruments. The aim of the present study is therefore to investigate the triadic interactions within the families of adolescents with anorexia nervosa using a semi-standardized observational tool based on a recorded play session, the Lausanne Trilogue Play (LTP). Parents and adolescent daughters, consecutively referred to adolescent neuropsychiatric services, participated in the study and underwent the observational procedure (LTP). The 20 families of adolescent girls with anorexia nervosa (restricting type) were compared with 20 families of patients with internalizing disorders (anxiety and depression). The results showed different interactive patterns in the families of adolescents with anorexia nervosa: they had greater difficulties in respecting roles during the play, maintaining the joint attention and in sharing positive affect, especially in the three-together phase (third phase). The majority of these families (12) exhibited collusive alliances. The parental subsystem appeared frequently unable to maintain a structuring role, i.e., providing help, support and guidance to the daughters, while the girls in turn often found it hard to show independent ideas and develop personal projects. Parents experienced difficulty in carving out a couple-specific relational space, from which the ill daughter was at least temporarily excluded also when they were asked to continue to interact with each other, letting the daughter be simply present in a third-part position (fourth phase). The study of the triadic interactions in the families of adolescents with anorexia nervosa may help to shift the attention from the exclusive mother-daughter relation to the involvement
Full Text Available Recently, neuromodulation techniques based on the use of repetitive transcranial magnetic stimulation (rTMS have been proposed as a non-invasive and efficient method to induce in vivo long-term potentiation (LTP-like aftereffects. However, the exact impact of rTMS-induced perturbations on the dynamics of neuronal population activity is not well understood. Here, in two monkeys, we examine changes in the oscillatory activity of the sensorimotor cortex following an intermittent theta burst stimulation (iTBS protocol. We first probed iTBS modulatory effects by testing the iTBS-induced facilitation of somatosensory evoked potentials (SEP. Then, we examined the frequency information of the electrocorticographic signal, obtained using a custom-made miniaturised multi-electrode array for electrocorticography, after real or sham iTBS. We observed that iTBS induced facilitation of SEPs and influenced spectral components of the signal, in both animals. The latter effect was more prominent on the θ band (4-8 Hz and the high γ band (55-90 Hz, de-potentiated and potentiated respectively. We additionally found that the multi-electrode array uniformity of β (13-26 Hz and high γ bands were also afflicted by iTBS. Our study suggests that enhanced cortical excitability promoted by iTBS parallels a dynamic reorganisation of the interested neural network. The effect in the γ band suggests a transient local modulation, possibly at the level of synaptic strength in interneurons. The effect in the θ band suggests the disruption of temporal coordination on larger spatial scales.

Full Text Available The theta-gamma cross-frequency coupling (CFC in hippocampus was reported to reflect memory process. In this study, we measured the CFC of hippocampal local field potentials (LFPs in a two-vessel occlusion (2VO rat model, combined with both amplitude and phase properties and associated with short and long-term plasticity indicating the memory function. Male Wistar rats were used and a 2VO model was established. STP and LTP were recorded in hippocampal CA3-CA1 pathway after LFPs were collected in both CA3 and CA1. Based on the data of relative power spectra and phase synchronization, it suggested that both the amplitude and phase coupling of either theta or gamma rhythm were involved in modulating the neural network in 2VO rats. In order to determine whether the CFC was also implicated in neural impairment in 2VO rats, the coupling of CA3 theta–CA1 gamma was measured by both phase-phase coupling (n:m phase synchronization and phase-amplitude coupling. The attenuated CFC strength in 2VO rats implied the impaired neural communication in the coordination of theta-gamma entraining process. Moreover, compared with modulation index (MI a novel algorithm named cross frequency conditional mutual information (CF-CMI, was developed to focus on the coupling between theta phase and the phase of gamma amplitude. The results suggest that the reduced CFC strength probably attributed to the disruption of the phase of CA1 gamma envelop. In conclusion, it implied that the phase coupling and CFC of hippocampal theta and gamma played an important role in supporting functions of neural network. Furthermore, synaptic plasticity on CA3-CA1 pathway was reduced in line with the decreased CFC strength from CA3 to CA1. It partly supported our hypothesis that directional CFC indicator might probably be used as a measure of synaptic plasticity.
Full Text Available Preterm birth has a critical influence on interactive, communicative, and expressive child behaviour, particularly during the first years of life. Few studies have stressed the assessment of mother-father-child interaction in families with preterm children, generating contradictory results. The present study wished to develop these fields: (i comparing the quality of family interactions between families with preterm children and families with children born at full term; (ii observing the development of family interactions after six months in the families with children born preterm; (iii assessing family and contextual factors, as parental stress and social support, in parents of preterm children in order to observe their influence on the quality of family interactions. 78 families are recruited: 39 families with preterm children (M = 19,8 months, SD = 11,05 and 39 families with full-term children (M = 19,66 months; SD = 13,10. Results show that families with preterm children display a low quality of mother-father-child interactions. After six months, family interactions result is generally stable, except for some LTP-scales reflecting a hard adjustment of parenting style to the evolution of the child. In families with preterm children, the parenting stress seemed to be correlated with the quality of mother-father-child interactions.

Cross-reactive proteins in small fruits of the Rosaceae family like strawberry, raspberry and blackberry revealed an unexpected complex IgE-reactivity pattern. Several copies of PR-10 and PR-14 proteins were detected by Southern blots in strawberry, raspberry and blackberry. In raspberry, the highest similarity at the DNA level for PR-10 and PR-14 (Rub i 1 and Rub i 3) was detected to strawberry sequences of Fra a 1 and Fra a 3. At the protein level, Rub i 1 and Rub i 3 showed more than 70% identity with homologous proteins of rosaceous fruits. Furthermore, raspberries contained additional putative allergens, e.g. class III acidic chitinases and cyclophilins. Blackberries were shown to share at least two well-known major fruit allergens with other rosaceous fruits, namely PR-10s and PR-14s homologous proteins. However the IgE-reactive proteins of small fruits are still not extensively investigated. The main challenges in studying small fruit allergens are the complexity of the fruit matrix, the diversity of physico-chemical properties of fruit proteins, the lack of appropriate protein extraction procedures and the missing information about the influence of processing treatments on food components.

This study describes the three-dimensional crystal structure of a non-specific lipid transport protein (ns-LTP) from Rosaceae. Whilst ns-LTPs from species other than Rosaceae, such as nuts, cereals, grape, oranges and vegetables are also responsible for plant food allergies, this is less frequent compared with ns-LTPs from Rosaceae in the Mediterranean area. In this heterologously expressed peach Pru p3, a ligand is present inside the central cavity of the protein, presumably a fatty acid that was present or produced in the culture medium of the expression organism Escherichia coli. Moreover, the two molecules of ns-LTP present in the asymmetric unit bind this ligand in a different way, suggesting a significant degree of plasticity for the peach ns-LTP binding cavity, despite the presence of four disulphide bridges. Two molecules are present in the asymmetric unit: molecule A is a fully liganded protein, while molecule B apparently represents a partially liganded state. Also, molecular dynamics simulation, along with other evidence, suggests that these two molecular conformations represent different states in solution. Comparison of the 3D models of different ns-LTPs justifies the evidence of a high degree of conservation of the putative IgE binding epitopes among proteins of the Rosaceae family and the presence of significant amino acid replacements in correspondence of the same regions in ns-LTPs of botanical species unrelated to Rosaceae.

The acronym IDEALS summarizes family physicians' obligations when violence is suspected: to identify family violence; document injuries; educate families and ensure safety for victims; access resources and coordinate care; co-operate in the legal process; and provide support for families. Failure to respond reflects personal and professional experience and attitudes, fear of legal involvement, and lack of knowledge. Risks of intervention include physician burnout, physician overfunctioning, escalation of violence, and family disruption. PMID:21228987

The study of the family in the Caribbean originated with European scholars who assumed the universality of the patriarchal nuclear family and the primacy of this structure to the healthy functioning of society. Matrifocal Caribbean families thus were seen as chaotic and disorganized and inadequate to perform the essential tasks of the social system. This article provides a more current discussion of the Jamaican family. It argues that its structure is the result of the agency and adaptation of its members and not the root cause of the increasing marginalization of peoples in the developing world. The article focuses on families living in poverty and how the family structure supports essential family functions, adaptations, and survival.

Even Grand Unified Theories may not explain the repetitive pattern of fermions in the Standard Model. The abysmal absence of dynamical information about these ''families'' is emphasized. The evidence that family quantum numbers exist, and are not conserved, is reviewed. It is argued that rare kaon decays may be the best means to obtain more information on this important question

Full Text Available An evaluation of the extraction of multiresidue pesticides from palm oil by liquid-liquid extraction/low-temperature purification (LLE/LTP coupled with dispersive solid-phase extraction (d-SPE as the cleanup procedure with the determination by liquid chromatography mass spectrometry using electrospray as the ionization source (LC-ESI-MS was carried out. Optimization approaches were studied in terms of d-SPE to select efficiency of type and mass of adsorbents to obtain the highest recovery yield of pesticides and the lowest coextract fat residues in the final extract. The optimal conditions of d-SPE were obtained using 3 g of palm oil, 4 g anhydrous MgSO4, 150 mg of PSA, and 50 mg of GCB (PSA: GCB (3 : 1 w/w. Recovery study was performed at three concentration levels (25, 50, and 100 ng kg−1, yielding recovery rates between 71.8 and 112.4% except diuron with relative standard deviations of 3.2–15.1%. Detection and quantification limits were lower than 2.7 and 8.2 ng kg−1, respectively. The proposed method was successfully applied to the analysis of market-purchased palm oil samples from two different brands collected in Kuala Lumpur, showing its potential applicability and revealing the presence of some of the target species in the ng g−1 range.

Between 1901-1921, India gained 12.9 million people because mortality remained high. The death rate fell between 1921-1951, but birth rates remained the same. Therefore 110 million people were added--2 times the population increase between 1891-1921. Between 1951-1981, the population increased to 324 million. Socioeconomic development was responsible for most of the downward trend in the birth rate during the 20th century. Even though large families were the norm in early India, religious leaders encouraged small family size. The 1st government family planning clinics in the world opened in Mysore and Bangalore in 1930. Right before Independence, the Bhore Committee made recommendations to reduce population growth such as increasing the age of marriage for girls. Since 1951 there has been a change in measures and policies geared towards population growth with each of the 7 5-Year Plans because policy makers applied what they learned from each previous plan. The 1st 5-Year Plan emphasized the need to understand what factors contribute to population growth. It also integrated family planning services into health services of hospitals and health centers. The government was over zealous in its implementation of the sterilization program (2nd 5-Year Plan, 1956-1961), however, which hurt family planning programs for many years. As of early 1992, sterilization, especially tubectomy, remained the most popular family planning method, however. The 7th 5-Year Plan changed its target of reaching a Net Reproductive Rate of 1 by 2001 to 2006-2011. It set a goal of 100% immunization coverage by 1990 but it did not occur. In 1986, the Ministry of Health and Family Welfare planned to make free contraceptives available in urban and rural areas and to involve voluntary organizations. The government needs to instill measures to increase women's status, women's literacy, and age of marriage as well as to eliminate poverty, ensure old age security, and ensure child survival and

We reported 63 macrocephalic children with special emphasis on 16 cases with familial macrocephaly. Of the 16 children with familial macrocephaly, 13 were boys. Foureen parents (13 fathers and 1 mother) had head sizes above 98th percentile. Three of 5 brothers and 5 of 8 sisters also had large heads. The head circumference at birth was known for 14 of the children and it was above the 98th percentile in 7 patients. Subsequent evaluations have shown the head size of these children to be following a normal growth curve. Some of the children were hypotonic as infants, but their development was generally normal. CT scans usually clearly distinguished these children from those with hydorocephalus. The familial macrocephalic children had ventricular measurements which were within the normal range, but absolute measurements of the ventricular size may be misleading, because the CT appearance was of mildly dilated ventricles in half of them.

Full Text Available The quality of family relations, observed during mother–father–infant triadic interactions, has been shown to be an important contributor to child social and affective development, beyond the quality of dyadic mother–child, father–child, and marital relationships. Triadic interactions have been well described in families with 3 month olds and older children using the Lausanne Trilogue Play (LTP. Little is known about the development of mother–father–baby interactions in the very 1st weeks postpartum, mostly because no specific observational setting or particular instrument had been designed to cover this age yet. To fill this gap, we adapted the LTP to create a new observational setting, namely the Diaper Change Play (DCP. Interactions are assessed using the Family Alliance Assessment Scales for DCP (FAAS-DCP. We present the validation of the DCP and its coding system, the FAAS-DCP. The three validation studies presented here (44 mother–father–child–triads involve a sample of parents with 3-week-old infants recruited in two maternity wards (n = 32 and n = 12 in Switzerland. Infants from both sites were all healthy according to their APGAR scores, weight at birth, and scores on the NICU Network Neurobehavioral Scale (NNNS, which was additionally conducted on the twelve infants recruited in one of the maternity ward. Results showed that the “FAAS – DCP” coding system has good psychometric properties, with a good internal consistency and a satisfying reliability among the three independent raters. Finally, the “FAAS-DCP” scores on the interactive dimensions are comparable to the similar dimensions in the FAAS-LTP. The results showed that there is no statistically significant difference on scores between the “FAAS-DCP” and the “FAAS,” which is consistent with previous studies underlying stability in triadic interaction patterns from pregnancy to 18 months. These first results indicated that the DCP is a promising

Family violence is a serious public health problem, the scale of which is seriously increasing in Morocco. Although it has existed for a long time, we ignore the real characteristics of this plague in our country; our work consisted in an epidemiological approach of family violence in Marrakech during 2006. After elaborating a questionnaire, which allows the study of the demographic and social profile of the families, the study of violence exercised in the family and the evaluation of the depression in the women, we led an inquiry amongst 265 women. Analysis of the results obtained has allowed us to underline the following characteristics: 16.6% of the women in our sample had been physically beaten; the young age is a risk factor; the age range most affected by violence is in women between the ages of 30 and 40 and which represent 39% of the battered women; domestic violence touches all the social, economic and cultural classes: in our study, 63% of the women having undergone violence were housewives, 25% were managers and 3% senior executives; family problems were the most important cause of violence in our study, representing 32.32%. Requests for money was the cause in 11.3% of the cases, and imposed sexual relations were found in 6.8% of the cases; alcoholism is an aggravating factor of family violence; 27.3% of the spouses who assaulted their wives were drunk; 52% of the assaulted women were victims of violence in childhood and 36% had been witness to their father's violence; in 63.6% of the cases of violence, the children were witnesses, and in 25% of the cases the children were victims of violence at the same time as their mothers; 50% of the women victims of violence did not react, while 38.6% left home, and 9.1 filed for divorce. Thirty-two percent of the assaulted woman had been traumatised by the aggression; the association of depression and violence was very high, 343% of the battered women in our study suffered from severe depression.

Bombyliidae is one of the largest Diptera families with more than 4,500 recognized species worldwide. Their species vary from robust to thin, and may be small to large (2-20mm) and looks like bees or wasps. They also present great variation in color. Adults can often be seen either resting and sunning themselves on trails, rocks or twigs or feeding on flowering plants as they are nectar feeders. All reared bee flies are predators or parasitoids of arthropods. The Colombian fauna of bombyliids comprises at the moment 22 species, and 12 genera, of which, six are endemic species. Nonetheless, this number may be much higher, as Colombia is a megadiverse country and there are not many specimens of this family deposited in collections all over the world.

The LISA Technology Package uses a heterodyne Mach-Zehnder interferometer to monitor the relative motion of the test masses with picometer accuracy. This paper discusses two classes of noise sources that were identified and investigated during the prototype experiments. Most troublesome are electrically induced sidebands on the light, which give rise to nonlinearities in the interferometer output. Even worse, if the differential pathlength between two optical fibres fluctuates, a noise term of milliradian amplitude appears and completely spoils the performance. We discuss the origin and mitigation of this process. Dissimilar beam shapes of the interfering beams produce another type of noise in conjunction with beam jitter and spatially inhomogeneous photodetectors. To study and minimize this effect, we have built a real-time high-resolution phasefront imaging system that will be used for the production of the flight model

The study examined the effectiveness of a culturally-adapted Strengthening Families Program (SFP) for Latinos to reduce risks for alcohol and drug use in children. Latino families, predominantly Puerto Rican, with a 9-12 year old child and a parent(s) with a substance abuse problem participated in the study. Pre- and post-tests were conducted with each family. Parental stress, parent-child dysfunctional relations, and child behavior problems were reduced in the families receiving the intervention; family hardiness and family attachment were improved. Findings contribute to the validation of the SFP with Latinos, and can be used to inform social work practice with Puerto Rican families.

Family therapy views humans not as separate entities, but as embedded in a network of relationships, highlighting the reciprocal influences of one's behaviours on one another. This article gives an overview of family demographics and the implementation of family therapy in Hong Kong. We start with a review of the family demographics in Hong Kong and brief notes on families in mainland China. Demographics show that the landscape has changed markedly in the past decade, with more cross-border marriages, an increased divorce rate, and an ageing overall population - all of which could mean that there is increasing demand for professional family therapy interventions. However, only a limited number of professionals are practising the systems-based approach in Hong Kong. Some possible reasons as to why family therapy is not well disseminated and practised are discussed. These reasons include a lack of mental health policy to support family therapy, a lack of systematic family therapy training, and a shortage of skilled professionals. Furthermore, challenges in applying the western model in Chinese culture are also outlined. We conclude that more future research is warranted to investigate how family therapy can be adapted for Chinese families.
Full Text Available Abstract Background Family doctors should care for individuals in the context of their family. Family has a powerful influence on health and illness and family interventions have been shown to improve health outcomes for a variety of health problems. The aim of the study was to investigate the Estonian family doctors' (FD attitudes to the patients' family-related issues in their work: to explore the degree of FDs involvement in family matters, their preparedness for management of family-related issues and their self-assessment of the ability to manage different family-related problems. Methods A random sample (n = 236 of all FDs in Estonia was investigated using a postal questionnaire. Altogether 151 FDs responded to the questionnaire (response rate 64%, while five of them were excluded as they did not actually work as FDs. Results Of the respondents, 90% thought that in managing the health problems of patients FDs should communicate and cooperate with family members. Although most of the family doctors agreed that modifying of the health damaging risk factors (smoking, alcohol and drug abuse of their patients and families is their task, one third of them felt that dealing with these problems is ineffective, or perceived themselves as poorly prepared or having too little time for such activities. Of the respondents, 58% (n = 83 were of the opinion that they could modify also relationship problems. Conclusions Estonian family doctors are favourably disposed to involvement in family-related problems, however, they need some additional training, especially in the field of relationship management.

Full Text Available The present paper scrutinizes the relationship between family emotional expressiveness (i.e., the tendency to express dominant and/or submissive positive and negative emotions and components of family structure as proposed in Olson’s Circumplex model (i.e., cohesion and flexibility, family communication, and satisfaction in families with adolescents. The study was conducted on a sample of 514 Slovenian adolescents, who filled out two questionnaires: the Slovenian version of Family Emotional Expressiveness - FEQ and FACES IV. The results revealed that all four basic dimensions of family functioning were significantly associated with higher/more frequent expressions of positive submissive emotions, as well as with lower/less frequent expressions of negative dominant emotions. Moreover, expressions of negative submissive emotions explained a small, but significant amount of variance in three out of four family functioning variables (satisfaction, flexibility, and communication. The importance of particular aspects of emotional expressiveness for family cohesion, flexibility, communication, and satisfaction is discussed, and the relevance of present findings for family counselling is outlined.
Family stories lie at the heart of psychoanalytic developmental theory and psychoanalytic clinical technique, but whose family? Increasingly, lesbian and gay families, multiparent families, and single-parent families are relying on modern reproductive technologies to form families. The contemplation of these nontraditional families and the vicissitudes of contemporary reproduction lead to an unknowing of what families are, including the ways in which psychoanalysts configure the family within developmental theory. This article focuses on the stories that families tell in order to account for their formation--stories that include narratives about parental union, parental sexuality, and conception. The author addresses three constructs that inform family stories and that require rethinking in light of the category crises posed by and for the nontraditional family: (1) normative logic, (2) family reverie and the construction of a family romance, and (3) the primal scene. These constructs are examined in tandem with detailed clinical material taken from the psychotherapy of a seven-year-old boy and his two mothers.

Family tourism is driven by the increasing importance placed on promoting family togetherness, keeping family bonds alive and creating family memories. Predictions for the future of family travel are shaped by changes in demography and social structures. With global mobility families are increasingly geographically dispersed and new family markets are emerging. The purpose of this paper is to discuss the trends that shape the understanding of families and family tourism. Design/methodology/approach – This paper examines ten trends that the authors as experts in the field identify of importance and significance for the future of family tourism. Findings – What emerges is that the future of family tourism lies in capturing the increasing heterogeneity, fluidity and mobility of the family market. Originality/value – The paper contributes to the understanding about the changes taking place in family tourism and what it means to the tourism industry in the future.

Full Text Available This study attempted to find a correlation between the trauma of family members of war and exile, and the characteristics of family functioning and lasted from 1992-1995. The term “family resilience” refers to the processes of adaptation and coping in the family as a functional unit. This paper presents a study of refugee families from Bosnia, who lived in refugee camps in Macedonia during the war of 1992- 1995. Data were obtained by interviews, observations, and a number of psychological instruments especially for children and parents, which measured the effects of psychological stress and family relationships. Based on the results obtained by quantitative and qualitative analysis, and application of theoretical models of systemic theory and family therapy, existence for four types of refugee families has been found and described, depending on the structure and the level of functionality.

Men's power is emphasized in the family power literature on marital decision making. Little attention has been paid to women's power, accrued through their deeper embeddedness in intrafamilial roles. Micro-level analysis of family power demonstrates that women's positions in the family power structure rest not on the horizontal marital tie but…

Fleeing civil war involves managing life threatening events and multiple disruptions of everyday life. The theoretical potentials of analysing the recreation of everyday family life among Syrian refugees in Denmark is explored based on conceptualizations that emphasize the collective agency...... of family members in social historical contexts. Studying the multiple perspectives of family members shows how social support conceptualized as care practises is conflictual in the changing everyday family practices that are transformed by policy. The purpose of studying how families manage to flee civil...... war and struggle to recreate an everyday life in exile is to contribute with contextualization and expansion of mainstream understandings of family life, suffering, and resilience in refugee family trajectories in multiple contexts....

This paper uses a unique dataset from Denmark to investigate (1) the role of family characteristics in corporate decision making, and (2) the consequences of these decisions on firm performance. We focus on the decision to appoint either a family or an external chief executive officer (CEO). We...... show that a departing CEO's family characteristics have a strong predictive power in explaining CEO succession decisions: family CEOs are more frequently selected the larger the size of the family, the higher the ratio of male children and when the departing CEOs had only had one spouse. We...... then analyze the impact of family successions on performance. We overcome endogeneity and omitted variables problems of previous papers in the literature by using the gender of a departing CEO's first-born child as an instrumental variable (IV) for family successions. This is a plausible IV as male first...

Objective: To analyze the clinical syndromes and inheritance patterns of multiplex families with epilepsy toward the ultimate aim of uncovering the underlying molecular genetic basis. Methods: Following the referral of families with 2 or more relatives with epilepsy, individuals were classified into epilepsy syndromes. Families were classified into syndromes where at least 2 family members had a specific diagnosis. Pedigrees were analyzed and molecular genetic studies were performed as appropriate. Results: A total of 211 families were ascertained over an 11-year period in Israel. A total of 169 were classified into broad familial epilepsy syndrome groups: 61 generalized, 22 focal, 24 febrile seizure syndromes, 33 special syndromes, and 29 mixed. A total of 42 families remained unclassified. Pathogenic variants were identified in 49/211 families (23%). The majority were found in established epilepsy genes (e.g., SCN1A, KCNQ2, CSTB), but in 11 families, this cohort contributed to the initial discovery (e.g., KCNT1, PCDH19, TBC1D24). We expand the phenotypic spectrum of established epilepsy genes by reporting a familial LAMC3 homozygous variant, where the predominant phenotype was epilepsy with myoclonic-atonic seizures, and a pathogenic SCN1A variant in a family where in 5 siblings the phenotype was broadly consistent with Dravet syndrome, a disorder that usually occurs sporadically. Conclusion: A total of 80% of families were successfully classified, with pathogenic variants identified in 23%. The successful characterization of familial electroclinical and inheritance patterns has highlighted the value of studying multiplex families and their contribution towards uncovering the genetic basis of the epilepsies.

Encopresis is a taboo symptom, which is connected with great suffering from mental pressure not only for the children concerned, but also their relatives. Family related approaches are indispensable to understand encopresis, because as a result of high symptom persistence and psychological comorbidity in many cases a purely behavior-therapeutic, symptom focused approach is not sufficient, and further psychotherapeutic interventions are necessary. There is a strong temporal correlation between family interaction and frequency of soiling and changes of interaction influence changes in soiling more than the other way round. In a literature review different family relationship patterns and approaches of family therapy are represented regarding encopresis. Meaningful differences for family therapy are represented regarding primary/secondary encopresis, encopresis with/without comorbid psychiatric disorder as well as encopresis with/without dysfunctional family interaction. Distinctions are made between symptom focused, not-symptom focused and combined family therapeutic approaches, which are illustrated with case examples of outpatient and inpatient treatment. Symptom focused family therapy like e.g. externalizing of the soiling is helpful also if no dysfunctional family interaction patterns are present, because all family members can contribute to treatment success according to their own resources.

Abstract Objective To examine trends in family medicine training at a time when substantial pedagogic change is under way, focusing on factors that relate to extended family medicine training. Design Aggregate-level secondary data analysis based on the Canadian Post-MD Education Registry. Setting Canada. Participants All Canadian citizens and permanent residents who were registered in postgraduate family medicine training programs within Canadian faculties of medicine from 1995 to 2013. Main outcome measures Number and proportion of family medicine residents exiting 2-year and extended (third-year and above) family medicine training programs, as well as the types and numbers of extended training programs offered in 2015. Results The proportion of family medicine trainees pursuing extended training almost doubled during the study period, going from 10.9% in 1995 to 21.1% in 2013. Men and Canadian medical graduates were more likely to take extended family medicine training. Among the 5 most recent family medicine exit cohorts (from 2009 to 2013), 25.9% of men completed extended training programs compared with 18.3% of women, and 23.1% of Canadian medical graduates completed extended training compared with 13.6% of international medical graduates. Family medicine programs vary substantially with respect to the proportion of their trainees who undertake extended training, ranging from a low of 12.3% to a high of 35.1% among trainees exiting from 2011 to 2013. Conclusion New initiatives, such as the Triple C Competency-based Curriculum, CanMEDS–Family Medicine, and Certificates of Added Competence, have emerged as part of family medicine education and credentialing. In acknowledgment of the potential effect of these initiatives, it is important that future research examine how pedagogic change and, in particular, extended training shapes the care family physicians offer their patients. As part of that research it will be important to measure the breadth and uptake of

To realize the broad and complex nature of the field of family psychology, I have slightly revised the mission statement of the Journal of Family Psychology (JFP) to capture contemporary scholarship in family psychology and to advance systems perspectives in this top-tier scientific journal. Over the next 6 years, I hope that authors will consider JFP as an outlet for their best work in the following areas: (1) JFP addresses societal challenges faced by families today; (2) JFP publishes important studies on what makes couple and family relationships work; (3) JFP is a leader in publishing reports that use cutting-edge sophisticated approaches to research design and data analysis; and (4) JFP imparts knowledge about effective therapy and prevention programs relevant to couples and families. The journal is also expanding its publication rate to eight issues per year. (c) 2016 APA, all rights reserved).

Keynote: Family relationships are normatively assumed to be characterized by ‘sharing’, such as living together in the same home, occupying the same place, sharing stuff, blood and biology, spending special and ordinary time together, and consequently creating shared biographical experiences....... In that way, families are thrown into togetherness. At the same time, we see families in varying forms where 'sharing' is lived and contested differently. In Denmark, many children live in nuclear families, and many live in different variations of more than one household. For those who share household...... and family, 'sharing' will be a basic condition. No matter what, they should share life circumstances, more stories, more places and spaces, more households families with both kin and non-kin.

Full Text Available Following an episode of typical transient global amnesia (TGA, a female patient reported similar clinical attacks in 2 maternal aunts. Prior reports of familial TGA are few, and no previous account of affected relatives more distant than siblings or parents was discovered in a literature survey. The aetiology of familial TGA is unknown. A pathophysiological mechanism akin to that in migraine attacks, comorbidity reported in a number of the examples of familial TGA, is one possibility. The study of familial TGA cases might facilitate the understanding of TGA aetiology.

It has been showed that people with schizophrenia from families that express high levels of criticism, hostility, or over involvement, have more frequent relapses than people with similar problems from families that tend to be less expressive of their emotions. Psychosocial interventions designed to reduce these levels of expressed emotions within families now exist for mental health workers. These interventions are proposed as adjuncts rather than alternatives to drug treatments, and their main purpose is to decrease the stress within the family and also the rate of relapse. To estimate the effects of family psychosocial interventions in community settings for the care of those with schizophrenia or schizophrenia-like conditions compared to standard care. Electronic searches of the Cochrane Library (Issue 2, 1998), the Cochrane Schizophrenia Group's Register (June 1998), EMBASE (1981-1995) and MEDLINE (1966-1995) were undertaken and supplemented with reference searching of the identified literature. Randomised or quasi-randomised studies were selected if they focused on families of people with schizophrenia or schizoaffective disorder and compared community-orientated family-based psychosocial intervention of more than five sessions to standard care. Data were reliably extracted, and, where appropriate and possible, summated. Peto odds ratios (OR), their 95% confidence intervals (CI) and number needed to treat (NNT) were estimated. The reviewers assume that people who died or dropped out had no improvement and tested the sensitivity of the final results to this assumption. Family intervention may decrease the frequency of relapse (one year OR 0.57 CI 0.4-0.8, NNT 6.5 CI 4-14). The trend over time of this main finding is towards the null and some small but negative studies may not have been identified by the search. Family intervention may decrease hospitalisation and encourage compliance with medication but data are few and equivocal. Family intervention does not

This presentation explores the question: What motivates the use of tracking technologies in families, and how does the use transform the relations between parent and child? The purpose is to investigate why tracking technologies are used in families and how these technologies potentially change...... the relation between parents and children. The use of tracking technologies in families implicate negotiations about the boundaries of trust and intimacy in parent-child relations which can lead to strategies of resistance or modification (Fotel and Thomsen, 2004; Rooney, 2010; Steeves and Jones, 2010......). In the presentation, we report from a qualitative study that focuses on intergenerational relations.

17 days were spent devoted to the effort of learning about China's educational approach to family planning in the hope of discovering how they are achieving their remarkable success in reducing population growth. As a member of the 1981 New York University/SIECUS Colloquim in China, it was necessary to rely on the translation provided by the excellent guides. Discussions were focused on questions prepared in advance about the topics that concerned the group. These observations, based on a short and limited exposure, cover the following areas: marriage and family planning policies; the family planning program; school programs; adult education; family planning workers; and unique aspects of the program. China has an official position on marriage and family planning that continues to undergo revisions. The new marriage law sets the minimum ages of marriage at 22 for men and 20 for women. Almost everyone marries, and an unmarried person over age 28 is a rarity. The family planning program in China is carried out by an extensive organizational network at national, provincial, and local government levels. Officials termed it a "propaganda campaign." Hospitals, clinics, and factories invariably displayed posters; a popular set of four presents the advantages of the 1 child family as follows: late marriage is best, for it allows more time to work and study; 1 child is best for the health of the mother; one gets free medical care for his/her child if a family has only 1 child; and there is more time to teach 1 child. The state operated television regularly explains the 1 child policy utilizing special films. According to 1 family planning official, "before marriage there is little sex." There are few abortions for unmarried women. Education about sex is for adults, for those persons who are about to be married. There is little if any sex education in schools. Sexual teaching is not generally acceptable, especially in the rural areas. By contrast, in Shanghai the physiology
Full Text Available The increasing trend of partnership disruption among families with children in recent decades has been accompanied by substantial changes in traditional gender roles in industrialized countries. Yet, relatively little is known about the effects of changing gender relations on family stability in the European context. In this paper, we study such gender influences at the familial and societal level in Sweden and Hungary between the mid-1960s and the early 1990s. We focus on the disruption of the first parental union (i.e. the union in which a couple's first child was born. Our analysis is based on data extracted from the Swedish and Hungarian Fertility and Family Surveys of 1992/93. We use the method of hazard regression. The results suggest (i that the establishment of the dual-earner family model influences family stability only if it is accompanied by some changes in traditional gender relations within the family, and (ii that women's and men's labor-market behavior have different effects in spite of the relatively long history of women's (also mothers' labor-force participation in both Sweden and Hungary.

Full Text Available Individuals with Disabilities Education Act (IDEA gives many rights to parents with special needs in terms of involvement and participation. Given the importance of family involvement in the special education process, and federal legislation that increasingly mandated and supported such involvement over time, considerable research has focused on the multiple ways that relationships between schools and families in the special education decision making process have played out. Educational professionals should create a positive climate for CLD families so that they feel more comfortable and therefore are able to participate more authentically and meaningfully.

We consider a generalization of the vicious walker problem in which N random walkers in R d are grouped into p families. Using field-theoretic renormalization group methods we calculate the asymptotic behaviour of the probability that no pairs of walkers from different families have met up to time t. For d > 2, this is constant, but for d -α , which we compute to O(ε 2 ) in an expansion in ε = 2 - d. The second-order term depends on the ratios of the diffusivities of the different families. In two dimensions, we find a logarithmic decay (ln t) -α-bar and compute α-bar exactly

Case managers mobilize family networks to care for patients. Family medical leave can be a resource for case managers who seek to enhance resilience among family caregivers. The Family Medical Leave Act, passed in 1993, was the first U.S. policy to regulate employee leaves from work for family care purposes (29 CFR 825.102). This policy offers family caregivers increased flexibility and equality. Current and emerging policies also can reduce financial strain. The discussion examines how case managers can integrate family medical leave into best-practice models to support patients and family caregivers.

Emphasis is placed on the heterogeneity of the phenotypic presentation of PCOD. It is the common expression of an unknown number of disorders and thus is a sign and not a specific diagnosis. Two essential features are arrested follicular maturation and atresia of follicles. Normal folliculogenesis is described, emphasizing that a large number of areas could be subject to derangement causing PCOD. Any interference of the finely balanced sequence of events can lead to PCOD. The genetic defect causing familial PCOD is unknown and the initiating event remains undefined. Three families are described that illustrate four features of familial PCOD. A number of associated disorders such as diabetes, hyperinsulinemia, obesity, and hypertension are described. The potential importance of agents that modulate the LH and FSH activity that may cause PCOD is emphasized. The theoretic means by which similar male and female gonadal abnormalities may be coupled in families through growth factors EGF and alpha TGF are presented.

Death is an event that always breaks into family life in a surprising way. Of all the deaths, suicide is the one which more strongly questions the functionality of a family and increases the risk of difficulties in the mourning process. Families in which a suicide has occurred are exposed to a greater possibility of disintegration, disorganization and pathological expressions in their members. To present a reduced and circumscribed narrative revision, restricted to examine the relationship between suicide and the mourning process in the family. The suicide of a loved one is an event that may contribute to pathological grief and mental dysfunctions in surviving relatives. Death in the family is a natural phenomenon. However, death by suicide is one of the phenomena that can generate more alterations in the structure and organization of the family, due to the difficulty related to the mourning process.

The mandolin family of instruments consists of plucked chordophones, each having eight strings in four double courses. With the exception of the mandobass, the courses are tuned in intervals of fifths, as are the strings in violin family instruments. The soprano member of the family is the mandolin, tuned G3-D4-A4-E5. The alto member of the family is the mandola, tuned C3-G3-D4-A4. The mandola is usually referred to simply as the mandola in the USA, but is called the tenor mandola in Europe. The tenor member of the family is the octave mandolin, tuned G2-D3-A3-E4. It is referred to as the octave mandolin in the USA, and as the octave mandola in Europe. The baritone member of the family is the mandocello, or mandoloncello, tuned C2-G2-D3-A3. A variant of the mandocello not common in the USA is the five-course liuto moderno, or simply liuto, designed for solo repertoire. Its courses are tuned C2-G2-D3-A3-E4. A mandobass was also made by more than one manufacturer during the early twentieth century, though none are manufactured today.

The present study investigates microaggressions toward individuals in lesbian, gay, bisexual, transgender, and queer (LGBTQ) families. Microaggressions are subtle forms of discrimination experienced on a daily basis as verbal or behavioral slights against individuals in oppressed groups. LGBTQ microaggressions are often studied at an individual level and understood as being directed toward an individual based on perceived identity. The present study allows for an understanding of bias directed at the family system level. Participants included 46 adults who identified as being part of an LGBTQ family. Participants completed an online questionnaire and described their experiences of LGBTQ family microaggressions. Thematic analysis revealed that LGBTQ family microaggressions were salient to individuals across multiple family roles. Three specific themes emerged: family legitimacy, conflicts with family values, and gender violation within family. These findings highlight the way LGBTQ microaggressions are influenced by cultural notions of family and impact the family system.

Bianchi, Suzanne M
American families and workplaces have both changed dramatically over the past half-century. Paid work by women has increased sharply, as has family instability. Education-related inequality in work hours and income has grown. These changes, says Suzanne Bianchi, pose differing work-life issues for parents at different points along the income distribution. Between 1975 and 2009, the labor force rate of mothers with children under age eighteen increased from 47.4 percent to 71.6 percent. Mothers today also return to work much sooner after the birth of a child than did mothers half a century ago. High divorce rates and a sharp rise in the share of births to unmarried mothers mean that more children are being raised by a single parent, usually their mother. Workplaces too have changed, observes Bianchi. Today's employees increasingly work nonstandard hours. The well-being of highly skilled workers and less-skilled workers has been diverging. For the former, work hours may be long, but income has soared. For lower-skill workers, the lack of "good jobs" disconnects fathers from family obligations. Men who cannot find work or have low earnings potential are much less likely to marry. For low-income women, many of whom are single parents, the work-family dilemma is how to care adequately for children and work enough hours to support them financially. Jobs for working-class and lower middle-class workers are relatively stable, except in economic downturns, but pay is low, and both parents must work full time to make ends meet. Family income is too high to qualify for government subsidized child care, but too low to afford high-quality care in the private market. These families struggle to have a reasonable family life and provide for their family's economic well-being. Bianchi concludes that the "work and family" problem has no one solution because it is not one problem. Some workers need more work and more money. Some need to take time off around the birth of a child

Youth who do not identify with or value their families (i.e., low family centrality) are considered to be at risk for maladjustment. However, the current study investigated whether low family centrality may be adaptive in negative family contexts (i.e., high family conflict) because youth's self-worth should be less tied to the quality of their family relationships. Multilevel models using daily diaries and latent variable interactions using longitudinal questionnaires indicated that, among a sample of 428 Mexican American adolescents (49.8% male, M age = 15.02 years), lower family centrality was generally detrimental to youth's well-being. However, for youth in adverse family environments, low family centrality ceased to function as a risk factor. The present findings suggest that family centrality values play a more nuanced role in youth well-being than previously believed, such that low family centrality may be an adaptive response to significant family challenges.

Gay and bisexual men may form chosen families in addition to or in place of families of origin. However, the characteristics of these diverse families remain largely unexamined in the quantitative literature. The purpose of this study was to develop a family typology based on responses from a racially and ethnically diverse sample of young adult gay and bisexual men (YGBM) recruited from the Detroit Metropolitan Area (N=350; 18-29 years old). To explore the role of family, we then examined family social support and social undermining in relation to YGBM psychological distress within different family types. A series of multivariate regressions were used to examine associations between family social support and social undermining with depression and anxiety outcomes. The majority (88%) of YGBM included family of origin in their definitions of family and 63% indicated having chosen families. Associations between family social processes and psychological outcomes varied by type of family, suggesting that family composition shapes how perceptions of support and undermining relate to experiencing symptoms of depression and anxiety. Chosen families play a prominent role in the lives of YGBM and should not be overlooked in family research. Findings also highlight the importance of examining co-occurring family social support and social stress processes to further address psychological distress symptoms among YGBM.
To examine family functioning in the families of psychiatric patients. Families of psychiatric patients and nonclinical families were compared. There were 60 families in each group. The instrument included a semistructured interview of family functioning and the Chulalongkorn Family Inventory (CFI), a self-report questionnaire designed to assess the perception of one's family. From the assessment by semistructured interview, 83.3% of psychiatric families and 45.0% of nonclinical families were found to be dysfunctional in at least one dimension. The difference was statistically significant (p dysfunctional dimensions in the psychiatric families was significantly higher than in the nonclinical control group, 3.5 +/- 1.9 and 0.98 +/- 1.5 respectively, p families were significantly lower than the control group, reflecting poor family functioning. The dysfunctions were mostly in the following dimensions: problem-solving, communication, affective responsiveness, affective involvement, and behavior control. Psychiatric families faced more psychosocial stressors and the average number of stressors was higher than the control families, 88.3% vs. 56.7% and 4.2 +/- 2.7 vs. 1.3 +/- 1.47 stressors respectively, p < 0.0001. Family functioning of psychiatric patients was less healthy than the nonclinical control. The present study underlined the significance of family assessment and family intervention in the comprehensive care of psychiatric patients.
Many of the 135 countries participating in the 1974 UN World Population Conference were far from accepting the basic human right to decide freely and responsibly the number and spacing of their children and to have the information, education, and means to do so. Considerable progress has been made since then, and the number of developing countries that provide direct government support for family planning has increased to over 60%. Many have liberalized laws and regulations which restricted access to modern contraceptive methods, and a growing number provide family planning services within their health care programs. A few have recognized the practice of family planning as a constitutional right. In late 1983 at the Second African Population Conference, recognition of family as a human right was strongly contested by several governments, particularly those of West Africa. in developed countries most of the women at risk of unwanted pregnancy are using contraceptives. Of the major developing regions the highest use level is in Latin America, wherein most countries 1/3 to 1/2 of married women are users. Levels in Asian countries range from up to 10% in Afghanistan, Nepal, and Pakistan to up to 40% in the southeastern countries. China, a special case, now probably exceeds an overall use level of 2/3 of married women. Contraceptive use is lowest in Africa. There is room for improvement even among many of the successful family planning programs, as access to contraceptives usually is not sufficient to overcome limiting factors. To ensure the individual's free choice and strengthen the acceptability and practice of family planning, all available methods should be provided in service programs and inluded in information and education activities. Family planning programs should engage local community groups, including voluntary organizations, in all aspects of planning, management, and allocation of resources. At the government level a clear political commitment to family
Full Text Available Gender stereotyping and gender role development is one of the debatable concerns to sociologists especially those who are interested in sociology of gender. This study attempts to investigate the role of family inculcating gender stereotyping in Pakhtun culture and its impact on gender role development conducted in public-sector universities of Malakand Division, Khyber Pakhtunkhwa province of Pakistan. The data were collected through in-depth interview method using interview guide as a tool of data collection. A sample size of 24 respondents consisting male and female students and teachers (8 samples from each university through purposive sampling technique was selected from three universities in the region, that is, University of Malakand, University of Swat, and Shaheed Benazir Bhutto University Sharingal (main campus. The collected information has been analyzed qualitatively where primary information has been linked with secondary data for further elaboration and attainment of grounded facts. The study reveals that gender stereotyping and gender role formation are sociocultural and relational constructs, which are developed and inculcated in the institutional network, social interaction, and social relationships especially in family. The study indicated that in family sphere, gender stereotyping and gender role formation are the outcome of gender socialization, differential familial environment, and parents’ differential role with children. The study recommends that gender-balanced familial environment, adopting the strategy of gender mainstreaming and positive role of media, can overcome gender stereotyping and reduce its impacts on gender and social role formation.
A $4 million Agency for International Development (AID) agreement was signed in Cairo September 30 which will help the Egyptian government increase family planning services. The project is in response to a request for up to $17 million of AID funds for family planning programs during the next 3 years. The funds will pay for: contract advisors to provide short-term in-country training of physicians, architectural and engineering services to renovate a hospital for family planning and obstetrics/gynecology training, and a field training site for family planning service providers. Some Egyptians will receive training in specialized areas in the U.S. and other countries. More than $1.5 million of the $4 million will finance local costs of goods and services required. In addition, it is anticipated that U.S.-owned local currencies will be obligated for direct support of U.S. technical personnel. Over the 3-year life of the project the $17 million from AID plus $664,000 of U.S.-owned local currency will cover 44% of the total costs of selected Egyptian family planning activities. The Egyptian government will contribute at least $18.4 million and the U.N. Fund for Population Activities and the International Bank for Reconstruction and Development will contribute $4.3 million.

Full Text Available At the present time the majority of nurse education programmes are firmly tied to the perspectives of curative medicine within hospitals - they are disease and hospital oriented. This model, which indicates a 'sickness’ concept of nursing is entirely inappropriate if contemporary and future health care needs are to be met. The shift in education should be towards a health, family and whole person centered approach. The family is the most fundamental and dynamic unit in society with a profound influence upon its members. Besides performing a variety of other functions, the family has a central role in promoting and maintaining the health of its members. Because the family unit is the microcosm of society and accurately reflects the needs of society at large it is appropriate that this should be a key area of experience. Family attachments during training provide opportunities for close and committed contact with people in their everyday world and for learning what is really important to them.
Full Text Available Professional associations and conferences have similarities with and differences from families and family reunions. This comparison can illustrate some ways professional associations can approach the integration of new members and the planning of conferences in order to facilitate membership development and leadership renewal. Unlike family reunions, professional conferences are not closed events that require a shared culture in order to fully participate; they are events that should show the constant change and development of practice that is representative of the profession – for both members and non-members. Some of the topics explored in the article are: making it easy for outsiders to contribute, considering the tastes of new members, making it easy to volunteer in a meaningful way, and remembering who the future of the organization is. These simple considerations will assist in opening professional associations to new participants and help them to maintain their relevance and vitality over time.

Familial gigantiform cementoma is a rate fibro-cemento-osseous disease of the jaws which appears to be transmitted as an autosomal dominant trait with variable expressivity of the phenotype. A 7-year-old girl visited DKUDH complaining of the painless facial deformity. Clinically, significant facie-lingual expansion was observed at the left maxilla, left mandibular body and symphysis portion. Malposition of lower anterior teeth was found. Panoramic radiograph and CT scan showed the extensive expandile mixed lesion at maxilla and mandible. Bone scan revealed hot spot at the maxilla and left side of mandible. Histologic examination revealed moderately dense fibrous connective tissue with scattered masses resembling cementum. The patient's mother had a history of the mandibular resection due to benign tumor. Her younger brother had buccal expansion of right mandible. We report our finding of a family that has exhibited clinical, radiographic and histologic findings consistent with the familial gigantiform dementoma.

We studied the characteristics of family functioning in bipolar children and healthy comparison children. We hypothesized that the family environment of bipolar children would show greater levels of dysfunction as measured by the Family Environment Scale (FES). We compared the family functioning of 36 families that included a child with DSM-IV bipolar disorder versus 29 comparison families that included only healthy children. All subjects and their parents were assessed with the K-SADS-PL interview. The parents completed the FES to assess their current family functioning. Multivariate analysis of variance was used to compare the family environment of families with and without offspring with bipolar disorder. Parents of bipolar children reported lower levels of family cohesion (pfamilies where a parent had a history of mood disorders compared to families where parents had no history of mood disorders. Length of illness in the affected child was inversely associated with family cohesion (r=-0.47, p=0.004). Due to the case-control design of the study, we cannot comment on the development of these family problems or attribute their cause specifically to child bipolar disorder. Families with bipolar children show dysfunctional patterns related to interpersonal interactions and personal growth. A distressed family environment should be addressed when treating children with bipolar disorder.

Since the mid-1970s the U.S. imprisonment rate has increased roughly fivefold. As Christopher Wildeman and Bruce Western explain, the effects of this sea change in the imprisonment rate--commonly called mass imprisonment or the prison boom--have been concentrated among those most likely to form fragile families: poor and minority men with little schooling. Imprisonment diminishes the earnings of adult men, compromises their health, reduces familial resources, and contributes to family breakup. It also adds to the deficits of poor children, thus ensuring that the effects of imprisonment on inequality are transferred intergenerationally. Perversely, incarceration has its most corrosive effects on families whose fathers were involved in neither domestic violence nor violent crime before being imprisoned. Because having a parent go to prison is now so common for poor, minority children and so negatively affects them, the authors argue that mass imprisonment may increase future racial and class inequality--and may even lead to more crime in the long-term, thereby undoing any benefits of the prison boom. U.S. crime policy has thus, in the name of public safety, produced more vulnerable families and reduced the life chances of their children. Wildeman and Western advocate several policy reforms, such as limiting prison time for drug offenders and for parolees who violate the technical conditions of their parole, reconsidering sentence enhancements for repeat offenders, and expanding supports for prisoners and ex-prisoners. But Wildeman and Western argue that criminal justice reform alone will not solve the problems of school failure, joblessness, untreated addiction, and mental illness that pave the way to prison. In fact, focusing solely on criminal justice reforms would repeat the mistakes the nation made during the prison boom: trying to solve deep social problems with criminal justice policies. Addressing those broad problems, they say, requires a greater social

Abstract Military life presents a variety of challenges to military families, including frequent separations and relocations as well as the risks that service members face during deployment; however, many families successfully navigate these challenges. Despite a recent emphasis on family resilience, the U.S. Department of Defense (DoD) does not have a standard and universally accepted definition of family resilience. A standard definition is a necessary for DoD to more effectively assess its efforts to sustain and improve family resilience. RAND authors reviewed the literature on family resilience and, in this study, recommend a definition that could be used DoD-wide. The authors also reviewed DoD policies related to family resilience, reviewed models that describe family resilience and identified key family resilience factors, and developed several recommendations for how family-resilience programs and policies could be managed across DoD.

Full Text Available Current paper describes the application of an innovative strategy to teach family, within a hospital context, by sensitizing nurses on the family subject through the use of a game. Given the hospitalization of a relative, the family faces changes in its dynamics caused by the crisis it is exposed to. It is the relevance for including the family within the care process. Since nurses are expected to assume a key role for which they need specific competence to intervene in families when experiencing an eventual crisis. The in-service education becomes a strategy of generating new skills and enhances human capital to improve the quality of nursing care. Considering the importance of including family in the care context, a playful tool called Family Nursing Game has been invented for teaching the family, especially by passing a model of family intervention. The strategy is based on the belief of the existence of relationship between game and learning.

Despite the large and growing numbers of adoptive families, little research describes interactions in families with adopted adolescents. Yet, adopted adolescents' increased risk for adjustment problems, combined with the association between family interactions and adolescent adjustment in nonadoptive families, raises questions about differences in adoptive and nonadoptive family interactions. We compared observed and self-reported family interactions between 284 adoptive and 208 nonadoptive families and within 123 families with 1 adopted and 1 nonadopted adolescent. Adolescents averaged 14.9 years of age. Comparisons were made using analysis of variance incorporating hierarchical linear methods in SAS PROC MIXED to control family-related correlations in the data. Parents and children reported more conflict in adoptive families when compared with nonadoptive families. Families with 1 adopted and 1 nonadopted adolescent reported more conflict between parents and adopted adolescents. Observed parental behavior was similar across adoptive and nonadoptive children although adopted adolescents were less warm and, in families with 2 adopted children, more conflictual than nonadopted adolescents. These findings suggest a need for further investigation of the association between family interactions and adopted adolescent problem behavior. Copyright 2009 APA, all rights reserved.

Aggressive chemotherapy protocols result in neutropenia in approximately half of all patients receiving chemotherapy. Thus, neutropenia continues to be a significant and potentially life-threatening side effect of treatment, even with use of colony-stimulating factors. Families of patients with neutropenia often provide the primary healing environment because most chemotherapy protocols are managed on an outpatient basis. To learn about the family's experience of managing chemotherapy-induced neutropenia (CIN), a grounded-theory methodology was used to analyze data from seven families. The central theme revealed by these families was "turbulent waiting with intensified connections." This meant that when families had a sense of greater vulnerability in response to the waiting after diagnosis of CIN, they connected intensely with each other and healthcare providers. Families reported that connections with nurses became more significant when neutropenia interrupted chemotherapy. Families also developed family caring strategies to manage this period of waiting for the chemotherapy to resume. These strategies included family inquiry, family vigilance, and family balancing. Nurses need to be aware of approaches to support the family's ability to manage CIN. Interventions and approaches constructed from the perspective of a family-professional partnership will enhance the family cancer experience as well as ongoing family growth and function.

This phase includes adjusting of theoretical concepts to the fieldwork displaying the results of the research and the analysis of the findings that put a family in the context of confronting different identities, above all national and regional. As possible "identity difference" was emphasized in the research, theoretical and methodological apparatus was adjusted to this goal. That is why in this paper the replies of interviewees that can suggest or reject the assumption that their national identity can influence significantly the evaluation of identity specificities are presented and analyzed, concerning more or less visible aspects of family life, like welfare status, relations between spouses, respect to the elder, family harmony, number of children, connections with relatives, etc.

TeenSmart International harnesses the power and flexibility of technology to empower youth to take personal responsibility for their health and lifestyle choices. Access to the Internet via mobile phones is often cheaper than paying to connect to a wired broadband service, and in rural areas, mobile networks may be the only means of accessing the Internet. This study assessed the feasibility, acceptability, and impact of "cues to action" or brief motivating cell phone text messages to improve adolescent family communication and relationships. A quasi-experimental design using a voluntary sample of 100 Nicaraguan youth at high risk for poor family communication participated. Pre- and posttest quantitative measures using Student t statistical analysis, a focus group, and a participant testimony provided the evaluation evidence. Findings suggest that there are economic and motivational barriers to the use of text messages, but when barriers are eliminated, the behavioral results are positive. Youth who received two weekly text messages over a 6-month period demonstrated statistically significant improvements in family communication perceptions, attitudes, and behaviors, strengthening their family communications and relationships. Brief and personalized text messaging "cues to action" may be a cost-effective intervention to improve adolescent healthy lifestyle behaviors.

India's goal of reducing the national birth rate by 50% by the year 2000 is destined to failure in the absence of attention to poverty, social inequality, and women's subordination--the factors that serve to perpetuate high fertility. There is a need to shift the emphasis of the population control effort from the obligation of individual women to curtail childbearing to the provision of the resources required for poor women to meet their basic needs. Female children are less likely to be educated or taken for medical care than their male counterparts and receive a lower proportion of the family's food supply. This discrimination stems, in large part, from parents' view that daughters will not be able to remunerate their families in later life for such investments. The myth of female nonproductivity that leads to the biased allocation of family resources overlooks the contribution of adult women's unpaid domestic labor and household production. Although government statistics state that women comprise 46% of India's agricultural labor force (and up to 90% of rural women participate in this sector on some basis), women have been excluded systematically from agricultural development schemes such as irrigation projects, credit, and mechanization. In the field of family planning, the Government's virtually exclusive focus on sterilization has excluded younger women who are not ready to terminate childbearing but would like methods such as condoms, diaphragms, IUDs, and oral contraceptives to space births. More general maternal-child health services are out of reach of the majority of poor rural women due to long distances that must be travelled to clinics India's birth rate could be reduced by 25% by 2000 just by filling the demand for quality voluntary family planning services. Without a sustained political commitment to improve the status of women in India, however, such gains will not be sustainable.

To help recruit and retain physicians, especially women, rural family practice groups need to establish policies regarding maternity and other family leaves. Also important are policies regarding paternity leave, adoptive leave, and leave to care for elderly parents. We surveyed members of the American Academy of Family Physicians in rural practice in 1995 to assess the prevalence of leave policies, the degree to which physicians are taking family leave, and the characteristics of ideal policies. Currently, both men and women physicians are taking family leaves of absence, which indicates a need for leave policies. Furthermore, a lack of family leave policies may deter women from entering rural practice.

Full Text Available Generally, researches with families focus the difficulties and the negative aspects of family life by bringing up their maladjustments and failures. The interest in family resilience contributes to change this logic by demonstrating the healthy aspects of the family world. Nevertheless, the term resilience presents ideological controversies which are more severe when the discussion is about families and poverty. In order to diminish these contradictions this study adopted a systemic concept of resilience which refers to “those processes that make possible to overcome adversities”. A case study was realized with a low income family who lived in a “very poor” neighborhood in the deep south of Brazil. The methodological strategies to the formal investigation of the family were: life history of the family using the principles of reflexive interview, genograms and data analyses through the approach of the grounded theory. The results showed that the family lived a number of risk experiences such as adoption, privation of basic needs, migration and diseases. Among the indicators of their abilities of “overcoming adversities”, emerged the belief system as the core of the discourses. The family showed that they value the interpersonal relationships through intra and extra familiar interactions based in the patterns of help, learning, affection and solidarity. During the crisis the family gives meaning to the difficulties in order to maintaining the situation controlled through cohesion, open communication, mutual respect and getting support of the extended family/ social network. The pos-adversity period is perceived as benefic and transforming as the family feels stronger and with feelings of solidarity, which is a mark of this family. Their attitude in relation to the neighborhood is active in the sense of promoting the welfare of other families who live in the same social address. Would those above identified processes be adequate to

In essentially all countries, responsibilities for child care, cooking, cleaning, and other homemaking tasks fall predominantly on the wife and mother. In addition, the childbearing years come during the period when a physicist must study hard, work long hours on research, and take temporary positions, often abroad. Thus, balancing family and career has long been one of the major barriers to women's participation in science and engineering fields, including physics. While many young women believe that they must choose between having children and having a science career, the fact is that the majority of women physicists in both developing and developed countries have successfully done both. This paper summarizes some ideas and recommendations raised in discussions, especially focused on easing the challenges of having children while in temporary jobs, returning to physics after a career break, the need for "family-friendly" working conditions, and the dual-career problem facing couples where both are scientists.

Full Text Available Familial Mediterranean Fever is an autosomal recessive inherited disease with a course of autoinflammation, which is characterized by the episodes of fever and serositis. It affects the populations from Mediterranean basin. Genetic mutation of the disease is on MEFV gene located on short arm of Chromosome 16. The disease is diagnosed based on clinical evaluation. Amyloidosis is the most important complication. The only agent that decreases the development of amyloidosis and the frequency and severity of the episodes is colchicine, which has been used for about 40 years. In this review, we aimed to discuss especially the most recent advances about Familial Mediterranean Fever which is commonly seen in our population.

Severe illness can disrupt family life, cause family dysfunction, strain resources, and cause caregiver burden. The family's ability to cope with crises depends on their resources. This study sought to assess families of children with cancer in terms of family function-dysfunction, family caregiver strain and the adequacy of family resources using a new family resources assessment instrument. This is a cross-sectional study involving 90 Filipino family caregivers of children undergoing cancer treatment. This used a self-administered questionnaire composed of a new 12-item family resources questionnaire (SCREEM-RES) based on the SCREEM method of analysis, Family APGAR to assess family function-dysfunction; and Modified Caregiver Strain Index to assess strain in caring for the patient. More than half of families were either moderately or severely dysfunctional. Close to half of caregivers were either predisposed to strain or experienced severe strain, majority disclosed that their families have inadequate economic resources; many also report inaccessibility to medical help in the community and insufficient educational resources to understand and care for their patients. Resources most often reported as adequate were: family's faith and religion; help from within the family and from health providers. SCREEM-RES showed to be reliable with Cronbach's alpha of 0.80. There is good inter-item correlation between items in each domain: 0.24-0.70. Internal consistency reliability for each domain was also good: 0.40-0.92. Using 2-point scoring system, Cronbach's alpha were slightly lower: full scale (0.70) and for each domain 0.26-.82. Results showed evidence of association between family resources and family function based on the family APGAR but none between family resources and caregiver strain and between family function and caregiver strain.

Discrete (family) symmetries might play an important role in models of elementary particle physics. We discuss the origin of such symmetries in the framework of consistent ultraviolet completions of the standard model in field and string theory. The symmetries can arise due to special geometrical properties of extra compact dimensions and the localization of fields in this geometrical landscape. We also comment on anomaly constraints for discrete symmetries.

There is little information about familial aggregation of insomnia; however, this type of information is important to (1) improve our understanding of insomnia risk factors and (2) to design more effective treatment and prevention programs. This study aimed to investigate evidence of familial aggregation of insomnia among first-degree relatives of probands with and without insomnia. Cases (n = 134) and controls (n = 145) enrolled in a larger epidemiological study were solicited to invite their first-degree relatives and spouses to complete a standardized sleep/insomnia survey. In total, 371 first-degree relatives (Mage = 51.9 years, SD = 18.0; 34.3% male) and 138 spouses (Mage = 55.5 years, SD = 12.2; 68.1% male) completed the survey assessing the nature, severity, and frequency of sleep disturbances. The dependent variable was insomnia in first-degree relatives and spouses. Familial aggregation was claimed if the risk of insomnia was significantly higher in the exposed (relatives of cases) compared to the unexposed cohort (relatives of controls). The risk of insomnia was also compared between spouses in the exposed (spouses of cases) and unexposed cohort (spouses of controls). The risk of insomnia in exposed and unexposed biological relatives was 18.6% and 10.4%, respectively, yielding a relative risk (RR) of 1.80 (p = .04) after controlling for age and sex. The risk of insomnia in exposed and unexposed spouses was 9.1% and 4.2%, respectively; however, corresponding RR of 2.13 (p = .28) did not differ significantly. Results demonstrate evidence of strong familial aggregation of insomnia. Additional research is warranted to further clarify and disentangle the relative contribution of genetic and environmental factors in insomnia. © Sleep Research Society 2016.

The name netrin is derived from the Sanskrit Netr, meaning 'guide'. Netrins are a family of extracellular proteins that direct cell and axon migration during embryogenesis. Three secreted netrins (netrins 1, 3 and 4), and two glycosylphosphatidylinositol (GPI)-anchored membrane proteins, netrins G1 and G2, have been identified in mammals. The secreted netrins are bifunctional, acting as attractants for some cell types and repellents for others. Receptors for the secreted netrins include the Deleted in Colorectal Cancer (DCC) family, the Down's syndrome cell adhesion molecule (DSCAM), and the UNC-5 homolog family: Unc5A, B, C and D in mammals. Netrin Gs do not appear to interact with these receptors, but regulate synaptic interactions between neurons by binding to the transmembrane netrin G ligands NGL1 and 2. The chemotropic function of secreted netrins has been best characterized with regard to axon guidance during the development of the nervous system. Extending axons are tipped by a flattened, membranous structure called the growth cone. Multiple extracellular guidance cues direct axonal growth cones to their ultimate targets where synapses form. Such cues can be locally derived (short-range), or can be secreted diffusible cues that allow target cells to signal axons from a distance (long-range). The secreted netrins function as short-range and long-range guidance cues in different circumstances. In addition to directing cell migration, functional roles for netrins have been identified in the regulation of cell adhesion, the maturation of cell morphology, cell survival and tumorigenesis.

Colorectal cancer (CRC), one of the most common cancers of the world, is actually a spectrum of several subtypes, with different molecular profiles, clinico-pathological characteristics and possibly separate pathways of progression. It is estimated that in approximately 25%-35% of cases, a familial component exists, so they are classified as familial CRC (fCRC). However the known hereditary CRC syndromes justify only up to 5%. The rest are attributed to some inherited genetic predisposition passed to offspring through low-penetrance genes, which in the proper environmental setting can bring on tumorigenesis. Furthermore, part of the familial clustering may be attributed to chance. Because of the complexity regarding the etiology of CRC, the clinician is sometimes faced with obscure patient data, and cannot be sure if they are dealing with fCRC or sporadic CRC. The elucidation of what is going on with the as yet "undefined" portion of CRC will aid not only in the diagnosis, classification and treatment of CRC, but more importantly in the proper adjustment of the screening guidelines and in genetic counselling of patients.

Wolfram syndrome (WS) is a rare autosomal recessive progressive neurodegenerative disorder, and it is mainly characterized by the presence of diabetes mellitus and optic atrophy. Other symptoms such as diabetes insipidus, deafness, and psychiatric disorders are less frequent. The WFS1 gene, responsible for the disease and encoding for a transmembrane protein called wolframin, was localized in 1998 on chromosome 4p16. In this report, we present a familial observation of Wolfram syndrome (parents and three children). The propositus was a 6-year-old girl with diabetes mellitus and progressive visual loss. Her family history showed a brother with diabetes mellitus, optic atrophy, and deafness since childhood and a sister with diabetes mellitus, optic atrophy, and bilateral hydronephrosis. Thus, association of these familial and personal symptoms is highly suggestive of Wolfram syndrome. The diagnosis was confirmed by molecular analysis (biology), which showed the presence of WFS1 homozygous mutations c.1113G>A (p.Trp371*) in the three siblings and a heterozygote mutation in the parents. Our observation has demonstrated that pediatricians should be aware of the possibility of Wolfram syndrome when diagnosing optic atrophy in diabetic children. Copyright © 2014 Elsevier Masson SAS.

Interventions to improve communication among family members may facilitate information flow about familial risk and preventive health behaviors. This is a secondary analysis of the effects of an interactive website intervention aimed at increasing communication frequency and agreement about health risk among melanoma families. Participants were family units, consisting of one family member with melanoma identified from a previous research study (the case) and an additional first degree relative and a parent of a child 0–17. Family triads were randomized to receive access to the website intervention or to serve as control families. Family communication frequency and agreement about melanoma prevention behaviors and beliefs were measured at baseline and again at one year post randomization. Intervention participants of all three types significantly increased the frequency of communication to their first degree relatives (Parents, siblings, children; range =14–18 percentage points; all pcommunication about cancer risk.

We investigate the possibility that family symmetry, Gsub(F), is spontaneously broken chiral global symmetry. We classify the interesting cases when family symmetry can result in an automatic Peccei-Quinn symmetry U(1)sub(PQ) and thus provide a solution to the strong CP problem. The result disfavors having two or four families. For more than four families, U(1)sub(PQ) is in general automatic. In the case of three families, a unique Higgs sector allows U(1)sub(PQ) in the simplest case of Gsub(F)=[SU(3)] 3 . Cosmological consideration also puts strong constraint on the number of families. For Gsub(F)=[SU(N)] 3 cosmology singles out the three-family (N=3) case as a unique solution if there are three light neutrinos. Possible implication of decoupling theorem as applied to family symmetry breaking is also discussed. (orig.)

Family oriented innovative programs extend the reach of many traditional out-of-school venues to involve the entire family in learning in comfortable and fun environments. Research shows that parental involvement is key to increasing student achievement outcomes, and family-oriented programs have a direct impact on student performance. Because families have the greatest influence on children's attitudes towards education and career choices, we have developed a Family Science program that provides families a venue where they can explore the importance of science and technology in our daily lives by engaging in learning activities that change their perception and understanding of science. NASA Family Science Night strives to change the way that students and their families participate in science, within the program and beyond. After three years of pilot implementation and assessment, our evaluation data shows that Family Science Night participants have positive change in their attitudes and involvement in science.  Even after a single session, families are more likely to engage in external science-related activities and are increasingly excited about science in their everyday lives.  As we enter our dissemination phase, NASA Family Science Night will be compiling and releasing initial evaluation results, and providing facilitator training and online support resources. Support for NASA Family Science Nights is provided in part through NASA ROSES grant NNH06ZDA001N.

The purpose of this interpretive descriptive study was to describe how eight Black-White couples with school-aged children constructed their interracial family identity through developmental transitions and interpreted race to their children. Within and across-case data analytic strategies were used to identify commonalities and variations in how Black men and White women in couple relationships formed their family identities over time. Coming together was the core theme described by the Black-White couples as they negotiated the process of forming a family identity. Four major tasks in the construction of interracial family identity emerged: (a) understanding and resolving family of origin chaos and turmoil, (b) transcending Black-White racial history, (c) articulating the interracial family's racial standpoint, and (d) explaining race to biracial children across the developmental stages. The findings guide family nurses in promoting family identity formation as a component of family health within the nurse-family partnership with Black-White mixed-race families.
Full Text Available The economic, cultural, and social transformation, growth of women's economic strength as well as the level of their education, and development of ideas of equal rights of women and men on the labour market and in social life cause changes in gender relation in the family. Poles more and more often declare and support egalitarian family, and a new model of a family appears among existing ones – dual-career family.The main aim of the article is to consider the sources of its rise, description of gender positions in marital relation, the division of tasks and responsibilities, possible dilemmas and conflicts, but also emotional, intellectual and social advantages. The analysis were put into context of changes in defining and describing family, and also in context of different family discourses. One of them was underlined the most – egalitarian one as the most approximate to the way of defining and understanding dual-career family model.

Full Text Available The 15-minute family interview is a condensed form of the Calgary Family Assessment and Intervention Models (CFAM and CFIM that aims to contribute to the establishment of a therapeutic relationship between nurses and family and to implement interventions to promote health and suffering relief, even during brief interactions. This study investigated the experience of nurses from the Family Health Strategy (FHS who used the 15-minute interview on postpartum home. The qualitative research was conducted in three stages: participants' training program, utilization of the 15-minute family interview by participants, and interviews with nurses. The data were collected through semi-structured interviews with eight nurses. The thematic analysis revealed two main themes: dealing with the challenge of a new practice and evaluating the assignment. This work shows that this tool can be used to deepen relationships between nurses and families in the Family Health Strategy.
This contribution is an essay about the notion of family identity reflecting shared significant experiences within a family system originating a set of signs used in social communication within and between families. Significant experiences are considered as experiences of events that have an immediate impact on the adaptation of the family in a given socio-ecological and cultural context at a given historical time. It is assumed that family history is stored in a shared "family memory" holding both implicit and explicit knowledge and exerting an influence on the behavior of each family member. This is described as transgenerational family memory being constituted of a system of meaningful signs. The crucial dimension underlying the logic of this essay are the ideas of adaptation as well as self-reproduction of systems.

It is well known that beam position monitors (BPM) utilizing signals from pickup electrodes (PUE) provide good resolution and relative accuracy. The absolute accuracy (i.e. position of the orbit in the vacuum chamber) is not very good due to the various reasons. To overcome the limitation it was suggested to use magnetic centers of quadrupoles for the calibration of the BPM . The proposed method provides accuracy better then 200 microns for centering of the beam position monitors using modulation of the whole quadrupole family

Vast amounts of money are currently being spent on policies aimed at promoting entrepreneurship. The success of such policies, however, rests in part on the assumption that individuals are not ‘born entrepreneurs’. In this paper, we assess the importance of family background and neighborhood...... effects as determinants of entrepreneurship. We start by estimating sibling correlations in entrepreneurship. We find that between 20 and 50 percent of the variance in different entrepreneurial outcomes is explained by factors that siblings share. The average is 28 percent.

Abstract Familial adenomatous polyposis (FAP) is characterized by the development of many tens to thousands of adenomas in the rectum and colon during the second decade of life. FAP has an incidence at birth of about 1/8,300, it manifests equally in both sexes, and accounts for less than 1% of colorectal cancer (CRC) cases. In the European Union, prevalence has been estimated at 1/11,300-37,600. Most patients are asymptomatic for years until the adenomas are large and numerous, and cause rect...
More than 45% of women scientists at top universities in the United States have indicated that their careers have kept them from having as many children as they want, according to an 8 August study, “Scientists want more children,” which appears in the journal PLoS ONE. The study, by sociologists Elaine Howard Ecklund of Rice University and Anne Lincoln of Southern Methodist University, indicates that 24.5% of male scientists surveyed indicated the same concerns. The study also found that among junior scientists, 29% of women indicated concern that a science career would prevent them from having a family; 7% of men indicated the same concern.

Although the majority of gastric carcinomas are sporadic, approximately 10% show familial aggregation, and a hereditary cause is determined in 1%-3% cases. Of these, hereditary diffuse gastric cancer is the most recognized predisposition syndrome. Although rare, the less commonly known syndromes also confer a markedly increased risk for development of gastric cancer. Identification and characterization of these syndromes require a multidisciplinary effort involving oncologists, surgeons, genetic counselors, biologists, and pathologists. This article reviews the molecular genetics, clinical and pathologic features, surveillance guidelines, and preventive measures of common and less common hereditary gastric cancer predisposition syndromes. ©AlphaMed Press.

This paper raises issues about the role of family members in providing support for breast cancer survivors. Data were collected from 400 breast cancer survivors in Peninsular Malaysia through a custom-designed questionnaire fielded at hospitals and support group meetings. The data were analyzed using descriptive statistics. The analyses show that all family members could be supportive, especially in decision making and help with emotional issues. The spouse was the main support provider among the family members (others were children, parents, siblings and more distant relatives). The results also indicated that a significant percentage practiced collaborative decision-making. Breast cancer survivors needed their family members' support for information on survivorship strategies such as managing emotions, health, life style and dietary practice. The family members' supportive role may be linked to the Malaysian strong family relationship culture. For family members to contribute more adequately to cancer survivorship, it is suggested that appropriate educational intervention also be provided to them.

During the NASA-Mir program of the 1990s and due to the challenges inherent in the International Space Station training schedule and operations tempo, it was clear that a special focus on supporting families was a key to overall mission success for the ISS crewmembers pre-, in- and post-flight. To that end, in January 2001 the first Family Services Coordinator was hired by the Behavioral Health and Performance group at NASA JSC and matrixed from Medical Operations into the Astronaut Office's organization. The initial roles and responsibilities were driven by critical needs, including facilitating family communication during training deployments, providing mission-specific and other relevant trainings for spouses, serving as liaison for families with NASA organizations such as Medical Operations, NASA management and the Astronaut Office, and providing assistance to ensure success of an Astronaut Spouses Group. The role of the Family Support Office (FSO) has modified as the ISS Program matured and the needs of families changed. The FSO is currently an integral part of the Astronaut Office's ISS Operations Branch. It still serves the critical function of providing information to families, as well as being the primary contact for US and international partner families with resources at JSC. Since crews launch and return on Russian vehicles, the FSO has the added responsibility for coordinating with Flight Crew Operations, the families, and their guests for Soyuz launches, landings, and Direct Return to Houston post-flight. This presentation will provide a summary of the family support services provided for astronauts, and how they have changed with the Program and families the FSO serves. Considerations for future FSO services will be discussed briefly as NASA proposes one year missions and beyond ISS missions. Learning Objective: 1) Obtain an understanding of the reasons a Family Support Office was important for NASA. 2) Become familiar with the services provided for

Familial hypercholesterolemia (FH) is a genetic disorder of lipoprotein metabolism resulting in elevated serum low-density lipoprotein (LDL) cholesterol levels leading to increased risk for premature cardiovascular diseases (CVDs). The diagnosis of this condition is based on clinical features, family history, and elevated LDL-cholesterol levels aided more recently by genetic testing. As the atherosclerotic burden is dependent on the degree and duration of exposure to raised LDL-cholesterol levels, early diagnosis and initiation of treatment is paramount. Statins are presently the mainstay in the management of these patients, although newer drugs, LDL apheresis, and other investigational therapies may play a role in certain subsets of FH, which are challenging to treat. Together these novel treatments have notably improved the prognosis of FH, especially that of the heterozygous patients. Despite these achievements, a majority of children fail to attain targeted lipid goals owing to persistent shortcomings in diagnosis, monitoring, and treatment. This review aims to highlight the screening, diagnosis, goals of therapy, and management options in patients with FH

Familial exudative vitreoretinopathy (FEVR) is a hereditary disease associated with visual loss, particularly in the pediatric group. Mutations in the NDP, FZD4, LRP5, and TSPAN12 genes have been shown to contribute to FEVR. FEVR has been reported to have X-linked recessive, autosomal dominant, and autosomal recessive inheritances. However, both the genotypic and phenotypic features are variable. Novel mutations contributing to the disease have been reported. The earliest and the most prominent finding of the disease is avascularity in the peripheral retina. As the disease progresses, retinal neovascularization, subretinal exudation, partial and total retinal detachment may occur, which may be associated with certain mutations. With early diagnosis and prompt management visual loss can be prevented with laser photocoagulation and anti-VEGF injections. In case of retinal detachment, pars plana vitrectomy alone or combined with scleral buckling should be considered. Identifying asymptomatic family members with various degrees of insidious findings is of certain importance. Wide-field imaging with fluorescein angiography is crucial in the management of this disease. The differential diagnosis includes other pediatric vitreoretinopathies such as Norrie disease, retinopathy of prematurity, and Coats' disease.
The Nigerian Family Health services project teamed up with the Johns Hopkins University's Population Communication Services to produce songs called "Choices" and "Wait for Me." The songs, which were about sexual responsibility, were performed by popular music stars King Sunny Ade and Onyeka Onwenu and appeared under King Sonny Ade's long playing albums in 1989. Teaching sexual responsibility through song was suggested in focus group discussions. Findings indicated that young people were responsive to messages about sexual responsibility, postponing sex or saying "no," male sexual responsibility, and children by informed choice and not chance among married couples. An impact assessment of the songs was conducted in February, 1991. Survey findings revealed that 64% of urban and 22% of rural respondents recalled having heard the songs and seen the videos. 48% of urban youth discussed the songs with friends, and 27% discussed the songs with sexual partners. 90% of respondents reported agreement with the message that couples should have only the number of children that they can care for, and that couples should practice family planning. The target population that was affected most by the songs was aged less than 35 years. The strategy of using songs to teach youth responsible parenting appears to be a reliable strategy for mass education and mobilization. There is mass support from among members of the National Council for Women's Societies, the Planned Parenthood Federation of Nigeria, and Coca Cola Corporation, as well as the public at large.
Family life education is not just instruction of sex and reproduction, but an attitude of love and values that starts from infancy. A child who comes into the world wanted is already loved. Later on, he himself will give love because his 1st contact in the world was a happy one. Most children will go through thumb sucking and masturbation, which is normal and innocent behavior. Toilet training is another important factor in sex education. According to our attitude the child will learn that this part of his body is good or bad. By the age of 3 or 6, children learn to discover the difference in sex from our attitude to each other, and when parents practice double standards, the child is confused and worried. Children's curiousity for knowledge is insatiable. If parents find they are embarressed by their children's questions about sex, it is better to put off answering than to convey the impression that something is not quite nice. 11-year old females should be prepared for menarche with knowledge, and fathers should explain to their sons about voice changes, night emissions and fantasy dreams. Masturbation is normal during adolescence, and the only harm comes from wrong anxiety about it. If 2 young people wish to have premarital intercourse, we must have the courage to tell them that chastity remains a value whether they accept it or not. Education for family life means taking account of the child's attitudes and sex values as a future marriage partner and parent.

In the European Union, prevalence has been estimated at 1/11,300-37,600. Most patients are asymptomatic for years until the adenomas are large and numerous, and cause rectal bleeding or even anemia, or cancer develops. Generally, cancers start to develop a decade after the appearance of the polyps. Nonspecific symptoms may include constipation or diarrhea, abdominal pain, palpable abdominal masses and weight loss. FAP may present with some extraintestinal manifestations such as osteomas, dental abnormalities (unerupted teeth, congenital absence of one or more teeth, supernumerary teeth, dentigerous cysts and odontomas, congenital hypertrophy of the retinal pigment epithelium (CHRPE, desmoid tumors, and extracolonic cancers (thyroid, liver, bile ducts and central nervous system. A less aggressive variant of FAP, attenuated FAP (AFAP, is characterized by fewer colorectal adenomatous polyps (usually 10 to 100, later age of adenoma appearance and a lower cancer risk. Some lesions (skull and mandible osteomas, dental abnormalities, and fibromas on the scalp, shoulders, arms and back are indicative of the Gardner variant of FAP. Classic FAP is inherited in an autosomal dominant manner and results from a germline mutation in the adenomatous polyposis (APC gene. Most patients (~70% have a family history of colorectal polyps and cancer. In a subset of individuals, a MUTYH mutation causes a recessively inherited polyposis condition, MUTYH-associated polyposis (MAP, which is characterized by a slightly increased risk of developing CRC and polyps/adenomas in both the upper and lower gastrointestinal tract. Diagnosis is based on a

WHY A TASK FORCE ON THE FAMILY? The practice of pediatrics is unique among medical specialties in many ways, among which is the nearly certain presence of a parent when health care services are provided for the patient. Regardless of whether parents or other family members are physically present, their influence is pervasive. Families are the most central and enduring influence in children's lives. Parents are also central in pediatric care. The health and well-being of children are inextricably linked to their parents' physical, emotional and social health, social circumstances, and child-rearing practices. The rising incidence of behavior problems among children attests to some families' inability to cope with the increasing stresses they are experiencing and their need for assistance. When a family's distress finds its voice in a child's symptoms, pediatricians are often parents' first source for help. There is enormous diversity among families-diversity in the composition of families, in their ethnic and racial heritage, in their religious and spiritual orientation, in how they communicate, in the time they spend together, in their commitment to individual family members, in their connections to their community, in their experiences, and in their ability to adapt to stress. Within families, individuals are different from one another as well. Pediatricians are especially sensitive to differences among children-in their temperaments and personalities, in their innate and learned abilities, and in how they view themselves and respond to the world around them. It is remarkable and a testament to the effort of parents and to the resilience of children that most families function well and most children succeed in life. Family life in the United States has been subjected to extensive scrutiny and frequent commentary, yet even when those activities have been informed by research, they tend to be influenced by personal experience within families and by individual and

Family health history about cancer is an important prevention and health promotion tool. Yet, few studies have identified family context factors that promote such discussions. We explored relations among family context (cohesion, flexibility, and openness), self-efficacy, and cancer communication (gathering family history, sharing cancer risk information, and frequency) in a diverse group of women enrolled in a randomized control trial. Baseline survey data for 472 women were analyzed. Average age was 34 years, 59% identified as Black, 31% graduated high school, and 75% reported a family history of any cancer. Results showed that greater family cohesion and flexibility were related to higher communication frequency and sharing cancer information. Women who reported greater self-efficacy were more likely to have gathered family history, shared cancer risk information, and communicated more frequently with relatives. Openness was not associated with communication but was related to greater family cohesion and flexibility. Adjusting for demographic variables, self-efficacy and family cohesion significantly predicted communication frequency. Women with higher self-efficacy were also more likely to have gathered family health history about cancer and shared cancer risk information. Future research may benefit from considering family organization and self-efficacy when developing psychosocial theories that, in turn, inform cancer prevention interventions. PMID:26735646

This qualitative study explored the kinds of worry that family caregivers experience when their older relatives are hospitalized. Little is known about what kinds of worries family caregivers may have in association with the hospitalizations of older relatives. An understanding of the different patterns of family worry may help health care teams intervene more effectively to meet family caregiver's needs by reducing their anxiety. A qualitative descriptive design with Loftland and Loftland (1984) approach for the study of a phenomenon occurring in a social setting was used. A purposeful sample of 10 participants was obtained that included six family caregivers and four nurses. Participants were recruited from two hospitals in the northwest US. Intensive interviews and participant observations were used for data collection, and Loftland and Loftland's (1984) qualitative approach was used for data analysis. Family worry was defined as family caregivers' felt difficulty in fulfilling their roles because of worry. Four categories of family worry were identified as a result of this study: (i) worry about the patient's condition; (ii) worry about the patient's care received from the health care team; (iii) worry about future care for the patient provided by the family caregiver; and (iv) worry about finances. The findings of this pilot study provide nurses with the initial knowledge of the typology of family worry associated with elderly relatives' hospitalizations. The findings of this study may sensitize the nurses to more precisely evaluate family caregivers' worry about their hospitalized elders and provide more effective nursing interventions to improve outcomes of both patients and their family caregivers.
Full Text Available OBJECTIVE: CADASIL (cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy is a systemic vasculopathy that causes various clinical pictures as recurrent ischemic attacks, migrainous headache, pseudo bulbar palsy, epileptic seizures and dementia. Mutations of notch3 gene on chromosome 19 are responsible for the disease. METHODS: The aim of this study is to draw attention to the family history and neuroradiological investigations of a genetically diagnosed CADASIL case. RESULTS: A forty-seven-years-old woman who presented with left hemiparesis was investigated for the cause of stroke as well as her family history. Her mother was reported to have chronic headache. Then inappropriate crying and laughing attacks, behavioral disturbances, urinary incontinency had contributed and she had died at the age of 51 following sudden loss of consciousness. Her father had had four stroke attacks after 45 and before he died at the age of 73 he was unresponsive for the last 10 years. First sibling, 58 years-old female had a history of three stroke attacks and reported forgetfulness. Second sibling, a female, suffered from headache and had died at the age of 37 succeeding two epileptic seizures. Third sibling, 53 years-old female was said to be living bedridden for the last 5 years. Fourth sibling was 51 years-old male and had had a stroke attack at the age of 38. Fifth sibling was 48 years-old female whose speech disorder started 10 years ago. Laughing and crying attacks, incontinency, childish behavior and forgetfulness were also added. Sixth sibling was our patient. Seventh sibling was 45 years-old, male and had no complaints. First, fourth, sixth and seventh siblings were evaluated in systematic, neurological, neuropsychological and neuroradiological perspectives. CONCLUSION: In addition to family history, hyperintensities in temporal polar region and external capsule on flair and T2-weighted MRI supported the diagnosis of

Religion is embedded in the culture of all societies. It influences matters of morality, ideology and decision making, which concern every human being at some point in their life. Although the different religions often lack a united view on matters such contraception and abortion, there is sometimes some dogmatic overlap when general religious principles are subject to the influence of local customs. Immigration and population flow add further complexities to societal views on reproductive issues. For example, present day Europe has recently faced a dramatic increase in refugee influx, which raises questions about the health care of immigrants and the effects of cultural and religious differences on reproductive health. Religious beliefs on family planning in, for example, Christianity, Judaism, Islam and Hinduism have grown from different backgrounds and perspectives. Understanding these differences may result in more culturally competent delivery of care by health care providers. This paper presents the teachings of the most widespread religions in Europe with regard to contraception and reproduction.

The superheavy symmetry breaking of the gauge group in supersymmetrized unified theories is studied. The requirement that supersymmetry be unbroken strongly constrains the possible gauge group breaking, and we systematize such constraints group theoretically. In model building, one issue is whether to permit an adjoint matter superfield with concomitant color exotic fermions. A second issue is that of naturalness which is complicated by the well-known supersymmetry non-renormalization theorems. Both with and without an adjoint matter superfield, the most promising group appears to be SU(9) where three families can be naturally accommodated, at least for low-energy gauge group SU(3) x SU(2) x U(1). With an extra U(1) factor, as advocated by Fayet, the non-renormalization theorem must be exploited. (orig.)

The primary skin lesion usually is grouped papules in an enlarging annular shape, with color ranging from flesh-colored to erythematous. The two most common types of granuloma annulare are localized, which typically is found on the lateral or dorsal surfaces of the hands and feet; and disseminated, which is widespread. Rarely, familial cases of granuloma annulare has been reported. Herein, we report two sisters with annular papules and plaques diagnosed as granuloma annulare with the clinical and pathological findings. [J Contemp Med 2015; 5(3.000: 189-191

Thus, this paper aims to provide a technological solution proposal, the Buscagro: a software application that can be used on mobile devices and towards to enable a better interaction between family farmers and buyers, allowing a greater display of products from the farmer and disclosure of interests of potential buyers. The features of this technology are based on farmers goods data and information products demanded by potential buyers. In this way, the software application performs combinations based on supply and demand data, generating results for producers to have access in how to find buyers and for consumers to find products a greater agility.

Full Text Available Pancreatic cancer’s high mortality rate equates closely with its incidence, thereby showing the need for development of biomarkers of its increased risk and a better understanding of its genetics, so that high-risk patients can be better targeted for screening and early potential lifesaving diagnosis. Its phenotypic and genotypic heterogeneity is extensive and requires careful scrutiny of its pattern of cancer associations, such as malignant melanoma associated with pancreatic cancer, in the familial atypical multiple mole melanoma syndrome, due to the CDKN2A germline mutation. This review is designed to depict several of the hereditary pancreatic cancer syndromes with particular attention given to the clinical application of this knowledge into improved control of pancreatic cancer.

to parents’ daily practices with their child. Contrary to the paradox in existing research between the ideal of gender equality on the one hand, and the differentiated and gender-based division of housework and care on the other, it is argued that changes are accruing even though parents still appear...... to adopt gender-based models when it comes to the day-to-day care and the distribution of domestic chores. Through empirical analyses it is demonstrated how the advent of the child becomes a fulcrum, and also how female and male parents’ expectations, beliefs and practises are rooted in traditional notions...... of complementary gender roles as well as in new understandings of gender equality based on ideals of mutual trust, respect and support. As a result, it is important to investigate how parenthood, family life and parental roles are constantly reflected upon and reproduced, negotiated and transformed through...
Full Text Available INTRODUCTION Stuttering is a functional impairment of speech, which is manifested by conscious, but nonintentionally interrupted, disharmonic and disrhythmic fluctuation of sound varying in frequency and intensity. Aetiology of this disorder has been conceived within the frame of theoretical models, which tend to connect genetic and epigenetic factors. OBJECTIVE The goal of the paper was to study the characteristics of the family functioning of stuttering children in comparison to the family functioning of children without speech disorder, which confirmed the justification of the introduction of family orientated therapeutic interventions into the therapy spectrum of child stuttering. METHOD Seventy-nine nucleus families of 3 to 6 year-old children were examined; of these, 39 families had stuttering children and 40 had children without speech disorder. The assessment of family characteristics was made using the Family Health Scale, an observer-rating scale which according to semistructured interview and operational criteria, measures 6 basic dimensions of family functioning: Emotional State, Communication, Borders, Alliances, Adaptability & Stability, Family Skills. A total score calculated from the basic dimensions, is considered as a global index of family health. RESULTS Families with stuttering children compared to families with children without speech disorder showed significantly lower scores in all the basic dimension of family functioning, as well as in the total score on the Family Health Scale. CONCLUSION Our research results have shown that stuttering children in comparison with children without speech disorder live in families with unfavorable emotional atmosphere, impaired communication and worse control over situational and developmental difficulties, which affect children's development and well-being. In the light of previous research, the application of family therapy modified according to the child's needs is now considered
Full Text Available Family is the most important educational environment. It is in the family that a child discovers the world of values. The opinions and attitude are shaped, traditions are recognized. A properly functioning family fulfils the basic needs for safety, love, security, and trust. Family shapes one's interests as well as securing and organising leisure time for children. The research conducted was to find an answer to the question: How does a family organize the leisure time of its children? The acquired data confirms the hypothesis that family organises the leisure time of its children and allows for the development of interests that foster the development of personality and introduce one to the world of values. Furthermore, a proper organisation of leisure time prevents the demoralisation of children and youth

Neutrino masses in the 100 eV-1 MeV range are permitted if there is a spontaneously broken global family symmetry that allows the heavy neutrinos to decay by Goldstone boson emission with a cosmologically acceptable lifetime. The family symmetry may be either abelian or nonabelian; we present models illustrating both possibilities. If the family symmetry is nonabelian, then the decay tau -> μ + Goldstone boson or tau -> e + Goldstone may have an observable rate. (orig.)

We analyze the families of non-autonomous systems of first-order ordinary differential equations admitting a common time-dependent superposition rule, i.e. a time-dependent map expressing any solution of each of these systems in terms of a generic set of particular solutions of the system and some constants. We next study the relations of these families, called Lie families, with the theory of Lie and quasi-Lie systems and apply our theory to provide common time-dependent superposition rules for certain Lie families.
Full Text Available Under Canada's four-year, $136 million Family Violence Initiative, the federal government is calling upon all Canadians to work in partnerships towards the elimination of family violence - child abuse, violence against women, and elder (senior abuse. Family violence is a complex problem and requires the efforts of all Canadians to resolve it. One of the key themes of the Initiative - a multidisciplinary approach to the problem of family violence - is reflected in the selection and development of projects. Activities funded by the seven federal departments and agencies involved in the Initiative emphasize partnerships with the professional, voluntary, corporate, non-government and government sectors.

In the United States, several states have made policy decisions regarding whether and how to use familial searching of the Combined DNA Index System (CODIS) database in criminal investigations. Familial searching pushes DNA typing beyond merely identifying individuals to detecting genetic relatedness, an application previously reserved for missing persons identifications and custody battles. The intentional search of CODIS for partial matches to an item of evidence offers law enforcement agencies a powerful tool for developing investigative leads, apprehending criminals, revitalizing cold cases and exonerating wrongfully convicted individuals. As familial searching involves a range of logistical, social, ethical and legal considerations, states are now grappling with policy options for implementing familial searching to balance crime fighting with its potential impact on society. When developing policies for familial searching, legislators should take into account the impact of familial searching on select populations and the need to minimize personal intrusion on relatives of individuals in the DNA database. This review describes the approaches used to narrow a suspect pool from a partial match search of CODIS and summarizes the economic, ethical, logistical and political challenges of implementing familial searching. We examine particular US state policies and the policy options adopted to address these issues. The aim of this review is to provide objective background information on the controversial approach of familial searching to inform policy decisions in this area. Herein we highlight key policy options and recommendations regarding effective utilization of familial searching that minimize harm to and afford maximum protection of US citizens.
Full Text Available Small businesses give a lot of possibilities for realization of your own creativity and inventivity. Employment of new family members creates work atmosphere that cannot be felt in other companies. Organizational culture results from the employee cohesion and from their devotion to the organization and to the work, and therefore cannot be achieved in other organizations and with any other motivational techniques. These excellent working conditions are a great base for fulfilling the organizational aims, as well as for united and satisfied family. The work in the family organizations is specific from two aspects: from the advantages that it offers and from the problems that arise from this kind of business. Knowing the conditions in the family business, i.e. knowing the factors that influence the effectiveness and efficiency of family business enables more efficient work. Family business development with change of generation or with the increase in the number of family members brings new moments. In addition, one good story can be transformed in an unpleasant conflict and can get to disunion in the family as well in the business. Knowing the possibilities and threats in connection to the factors that influence the family business enables preventive actions in order to avoid undesirable situations.

Through the collaboration of a network of public and private consultants, we recruited n=181 adolescents diagnosed for EDs (n=61 with AN, n=60 with BN, and n=60 with BEDs and their parents. Mothers, fathers, and youths were assessed through a self-report measure evaluating family functioning, and adolescents completed a self-report questionnaire assessing psychopathological symptoms. Results showed specific family functioning and psychopathological profiles based on adolescents’ diagnosis. Regression analyses also showed that family functioning characterized by rigidity predicted higher psychopathological symptoms. Our study underlines the importance of involving all members of the family in assessment and intervention programs when adolescent offspring suffer from EDs.

Understanding patterns of family response to childhood chronic conditions provides a more comprehensive understanding of their influence on family and child functioning. In this paper, we report the results of a cluster analysis based on the six scales comprising the Family Management Measure (FaMM) and the resulting typology of family management. The sample of 575 parents (414 families) of children with diverse chronic conditions fell into four patterns of response (Family Focused, Somewhat Family Focused, Somewhat Condition Focused, Condition Focused) that differed in the extent family life was focused on usual family routines or the demands of condition management. Most (57%) families were in either the Family Focused or Somewhat Family Focused pattern. Patterns of family management were related significantly to family and child functioning, with families in the Family Focused and Somewhat Family Focused patterns demonstrating significantly better family and child functioning than families in the other two patterns.

Familial risks of glomerulonephritis (acute, chronic and unspecified glomerulonephritis) have not been studied. This study aims to determine the familial risks of glomerulonephritis. Individuals born from1932 onwards diagnosed with glomerulonephritis (acute [n = 7011], chronic [n = 10,242] and unspecified glomerulonephritis [n = 5762]) were included. The familial risk (Standardized incidence ratio = SIR) was calculated for individuals whose parents/full-siblings were diagnosed with glomerulonephritis compared to those whose parents/full-siblings were not. The procedure was repeated for spouses. Familial concordant risk (same disease in proband and exposed relative) and discordant risk (different disease in proband and exposed relative) of glomerulonephritis were determined. Familial concordant risks (parents/full-sibling history) were: SIR = 3.57 (95% confidence interval, 2.77-4.53) for acute glomerulonephritis, SIR = 3.84 (3.37-4.36) for chronic glomerulonephritis and SIR = 3.75 (2.85-4.83) for unspecified glomerulonephritis. High familial risks were observed if two or more relatives were affected; the SIR was 209.83 (150.51-284.87) in individuals with at least one affected parent as well as one full-sibling. The spouse risk was only moderately increased (SIR = 1.53, 1.33-1.75). Family history of glomerulonephritis is a strong predictor for glomerulonephritis, and is a potentially useful tool in clinical risk assessment. Our data emphasize the contribution of familial factors to the glomerulonephritis burden in the community. Key Messages The familial risks (full-sibling/parent history) of glomerulonephritis (acute, chronic and unspecified glomerulonephritis) have not been determined previously. The familial risks of glomerulonephritis were increased among individuals with family history of acute, chronic or unspecified glomerulonephritis. The familial risks of glomerulonephritis were slightly increased among spouses indicating a

Type classes and type families are key ingredients in Haskell programming. Type classes were introduced to deal with ad-hoc polymorphism, although with the introduction of functional dependencies, their use expanded to type-level programming. Type families also allow encoding type-level functions......, now as rewrite rules. This paper looks at the interplay of type classes and type families, and how to deal with shortcomings in both of them. Furthermore, we show how to use families to simulate classes at the type level. However, type families alone are not enough for simulating a central feature...... of type classes: elaboration, that is, generating code from the derivation of a rewriting. We look at ways to solve this problem in current Haskell, and propose an extension to allow elaboration during the rewriting phase....

Adolescence is characterized by an increase in autonomy and the transformation of family relationships. Their experience has different meanings in future quality of life. To analyze the relationship between the sociodemographic variables, of Sexual context and attitudes adopted by teenagers facing sexuality with the organizational culture of the family. Observational descriptive and correlational, transversal study. The non-probabilistic convenience sample consists of 1216 adolescents attending the 9th year of study in Portuguese Public Schools and is part of the project PTDC/CPE-CED/103313/2008, the questionnaire applied was family organizational culture of Nave (2007) and attitudes towards sexuality of Nelas et al (2010). The majority lives in a village (47.5% of boys and 50.0% girls) .12.9%of boys do not use condoms in all relationships, and the same applies to 17.8% of girls. They belong mostly (55.8% boys and 49.5% girls) to a family with poor interpersonal relationships culture. The majority (51.8%) males and (58.9%) females have a family with moderate heuristic culture. Boys and girls (33.6% and 36.9%) both demonstrate a predominantly moderate hierarchy family culture and a moderate social goals family culture as well. Adolescents who have a bad attitude towards sexuality, mostly (43.2%) present a weak interpersonal relationships family culture with statistical significance (χ(2)=32,092, p=0.000) and have moderate hierarchy family culture and also moderate social goals family culture, without statistical significance. The family that loves, welcomes and cares is the same that educates and informs about sexuality, promoting youth empowerment making them safer, healthier and happier.

Full Text Available Abstract Background Chemoreceptor proteins mediate the first step in the transduction of environmental chemical stimuli, defining the breadth of detection and conferring stimulus specificity. Animal genomes contain families of genes encoding chemoreceptors that mediate taste, olfaction, and pheromone responses. The size and diversity of these families reflect the biology of chemoperception in specific species. Results Based on manual curation and sequence comparisons among putative G-protein-coupled chemoreceptor genes in the nematode Caenorhabditis elegans, we identified approximately 1300 genes and 400 pseudogenes in the 19 largest gene families, most of which fall into larger superfamilies. In the related species C. briggsae and C. remanei, we identified most or all genes in each of the 19 families. For most families, C. elegans has the largest number of genes and C. briggsae the smallest number, suggesting changes in the importance of chemoperception among the species. Protein trees reveal family-specific and species-specific patterns of gene duplication and gene loss. The frequency of strict orthologs varies among the families, from just over 50% in two families to less than 5% in three families. Several families include large species-specific expansions, mostly in C. elegans and C. remanei. Conclusion Chemoreceptor gene families in Caenorhabditis species are large and evolutionarily dynamic as a result of gene duplication and gene loss. These dynamics shape the chemoreceptor gene complements in Caenorhabditis species and define the receptor space available for chemosensory responses. To explain these patterns, we propose the gray pawn hypothesis: individual genes are of little significance, but the aggregate of a large number of diverse genes is required to cover a large phenotype space.

It is now well accepted that a woman can conceive from an act of intercourse for a maximum of only about 7 days of her menstrual cycle. The reliability of natural family planning depends on identifying this window of fertility without ambiguity. Several symptomatic markers, cervical mucus and basal body temperature, have been used extensively and with considerable success in most women but failures occur. Ovarian and pituitary hormone production show characteristic patterns during the cycle. Urinary estrogen and pregnanediol measurements yield reliable information concerning the beginning, peak, and end of the fertile period, provided that the assays are accurate and performed on timed specimens of urine. We have developed such enzyme immunoassays for urinary estrogen and pregnanediol glucuronides that can be performed at home. In the early versions of the assays, enzyme reaction rates were measured by eye, but more recently, a simple photoelectronic rate meter has been used. The final problem to be solved is not technologic but whether women are sufficiently motivated to expend the same time and effort each day for 10 days a month, with less cost, on fertility awareness as they spend on making a cup of tea.
Increasing membership of the CERN family featured strongly at the CERN Council meetings this week, with Serbia’s ratification documents being received along with an application for Associate Membership from Ukraine. We also learned that an official application is on its way from Brazil and I can report that discussions are ongoing with several other countries around the world. Serbia joins Israel as an Associate Member in the pre-stage to Membership, and since Yugoslavia was a founder member of CERN in 1954, it was good to welcome Belgrade back. Looking forward, the Council has agreed to set up fast fact finding missions to other applicant countries, so I think it’s fair to say that 2012 will be a year of growth for CERN, fulfilling our mission of science bringing nations together. In a similar vein, it was a pleasure for me to be able to report to the Council an important development at SESAME, the light source for the Middle East established in Jordan on the CERN mode...

There is a large body of research that shows children from non-intact homes show higher rates of juvenile delinquency than children from intact homes, partially due to weaker parental control and supervision in non-intact homes. What has not been adequately addressed in the research is the influence of changes in family structure among individual adolescents over time on delinquent offending. Using the first and third waves of the National Youth Study, we assess the effect of family structure changes on changes in delinquent offending between waves through the intermediate process of changes in family time and parental attachment. Although prior research has documented adolescents in broken homes are more delinquent than youth in intact homes, the process of family dissolution is not associated with concurrent increases in offending. In contrast, family formation through marriage or cohabitation is associated with simultaneous increases in offending. Changes in family time and parental attachment account for a portion of the family formation effect on delinquency, and prior parental attachment and juvenile offending significantly condition the effect of family formation on offending.

Molecular genetic analysis of familial and non-familial cases of conventional renal cell carcinoma (RCC) revealed a critical role(s) for multiple genes on human chromosome 3. For some of these genes, e.g. VHL, such a role has been firmly established, whereas for others, definite confirmation is still pending. Additionally, a novel role for constitutional chromosome 3 translocations as risk factors for conventional RCC development is rapidly emerging. Also, several candidate loci have been mapped to other chromosomes in both familial and non-familial RCCs of distinct histologic subtypes. The MET gene on chromosome 7, for example, was found to be involved in both forms of papillary RCC. A PRCC-TFE3 fusion gene is typically encountered in t(X;1)-positive non-familial papillary RCCs and results in abrogation of the cell cycle mitotic spindle checkpoint in a dominant-negative fashion, thus leading to RCC. Together, these data turn human RCC into a model system in which different aspects of both familial and non-familial syndromes may act as novel paradigms for cancer development.

The Shodagor of Matlab, Bangladesh, are a seminomadic community of people who live and work on small wooden boats, within the extensive system of rivers and canals that traverse the country. This unique ecology places particular constraints on family and economic life and leads to Shodagor parents employing one of four distinct strategies to balance childcare and provisioning needs. The purpose of this paper is to understand the conditions that lead a family to choose one strategy over another by testing predictions about socioecological factors that impact the sexual division of labor, including a family's stage in the domestic cycle, aspects of the local ecology, and the availability of alloparents. Results show that although each factor has an impact on the division of labor individually, a confluence of these factors best explains within-group, between-family differences in how mothers and fathers divide subsistence and childcare labor. These factors also interact in particular ways for Shodagor families, and it appears that families choose their economic strategies based on the constellation of constraints that they face. The results of these analyses have implications for theory regarding the sexual division of labor across cultures and inform how Shodagor family economic and parenting strategies should be contextualized in future studies.

The implications of a recently indicated increase in τ lifetime are discussed. It is stressed that the available experimental constraints (from δρ,ε 3 , and N ν , etc.) are satisfied most naturally if the indicated τ anomaly is attributed to the mixing of the τ family with a heavy vectorlike family Q L, R ' with masses ∼200 GeV to 2 TeV, which is a doublet of SU(2) R and singlet of SU(2) L , rather than with a heavy fourth family with standard chiral couplings. L↔R symmetry would imply that Q L, R ' is accompanied by the parity-conjugate family Q L, R which is a doublet of SU(2) L and singlet of SU(2) R . Two such vectorlike families, together with an increase in τ τ , are, in fact, crucial predictions of a recently proposed supersymmetric composite model that possesses many attractive features, in particular, explanations of the origin of diverse scales and family replication. In the context of such a model, it is noted that 3 an increase in τ τ due to mixing involving vectorlike families will necessarily imply a correlated decrease in neutrino counting N ν from the CERN e + e- collider LEP from 3. Such a decrease in N ν would be absent, however, if the τ anomaly is attributed to a mixing involving a standard fourth family with chiral couplings. Because of the seesaw nature of the mass matrix of the three chiral and two vectorlike families, that arises naturally in the model, departures from universality in the first two families as well as in bar bb and τ + τ - channels (linked to down flavors) are strongly suppressed, in accord with observations
Migration is very often a family affair, and often involves children, directly or indirectly. It may give rise to better quality of life for an entire family, or to bitter disappointment, and may also increase vulnerability to HIV and AIDS. This review, carried out for the Joint Learning Initiative on Children and AIDS, links the literature on "migration", on "HIV and AIDS" and on "families". Three themes are sketched: (1) As both HIV prevalence and circular migration increase, former migrant workers affected by AIDS may return to their families for care and support, especially at the end of life, often under crisis conditions. Families thus lose promising members, as well as sources of support. However, very little is known about the children of such migrants. (2) Following patterns of migration established for far different reasons, children may have to relocate to different places, sometimes over long distances, if their AIDS-affected parents can no longer care for them. They face the same adaptation challenges as other children who move, but complicated by loss of parent(s), AIDS stigma, and often poverty. (3) The issue of migrant families living with HIV has been studied to some extent, but mainly in developed countries with a long history of migration, and with little attention paid to the children in such families. Difficulties include involuntary separation from family members, isolation and lack of support, disclosure and planning for children's care should the parent(s) die and differences in treatment access within the same family. Numerous research and policy gaps are defined regarding the three themes, and a call is made for thinking about migration, families and AIDS to go beyond description to include resilience theory, and to go beyond prevention to include care.

Inadequate social support is an important determinant of postpartum depression (PPD). Social support for pregnant women consists of supports from various sources and can be measured at different gestation periods. Differentiating the effects of social support from different sources and measured at different gestation periods may have important implications in the prevention of PPD. In the family centred Chinese culture, family support is likely to be one of the most important components in social support. The aim of this study was to assess the association of prenatal family support and postnatal family support with PPD. A prospective cohort study was conducted between February and September 2007 in Hunan, China. Family support was measured with social support rating scale at 30-32 weeks of gestation (prenatal support) and again at 2 weeks of postpartum visit (postnatal support). PPD was defined as Edinburgh Postnatal Depression Scale (EPDS) score > or =13. A total of 534 pregnant women were included, and among them, 103 (19.3%) scored 13 or more on the EPDS. PPD was 19.4% in the lowest tertile versus 18.4% in the highest quartile (adjusted odds ratio: 1.04, 95% confidence interval 0.60, 1.80) for prenatal support from all family members, and PPD was 39.8% in the lowest tertile versus 9.6% in the highest tertile (adjusted odds ratio: 4.4, 95% confidence interval 2.3, 8.4) for postnatal support from all family members. Among family members, support from husband had the largest impact on the risk of developing PPD. Lack of postnatal family support, especially the support from husband, is an important risk factor of PPD.
Full Text Available EnglishSocial cohesion can be viewed in terms of common projects and networks of social relations that characterize families, communities and society. In the past decades, the basis for family cohesion has shifted from organic to mechanical or from breadwinner to collaborative model. As in many Western countries, data on family change in Canada point to a greater flexibility in the entry and exit from relationships, a delay in the timing of family events, and a diversity of family forms. After looking at changes in families and in the family setting of individuals, the paper considers both intra-family cohesion and families as basis for social cohesion. Implications are raised for adults, children and publicp olicy.FrenchLa cohésion sociale peut se voir à travers les projets communs et les réseaux desrelations sociales qui caractérisent les familles, les communautés et les sociétés.La base de cohésion familiale est passée d’organique à mécanique, pour utiliserles termes de Durkheim, ou vers un modèle de collaboration plutôt qu’unepartage asymétrique de tâches. Comme dans d’autres sociétés orientales, lafamille au Canada est devenue plus flexible par rapport aux entrées et sortiesd’unions, il y a un délais dans les événements familiaux, et une variété deformes de familles.

At present there is evidence from neutrino oscillation searches that the neutrinos are in fact massive particles and that they mix. If confirmed, this would imply that the conservation of LFN is not exact. Lepton family number violation (LFNV) has been searched for with impressive sensitivities in many processes involving charged leptons. The present experimental limits on some of them (those which the author shall consider here) are shown in Table 1. These stringent limits are not inconsistent with the neutrino oscillation results since, given the experimental bounds on the masses of the known neutrinos and the neutrino mass squared differences required by the oscillation results, the effects of LFNV from neutrino mixing would be too small to be seen elsewhere (see Section 2). The purpose of experiments searching for LFNV involving the charged leptons is to probe the existence of other sources of LFNV. Such sources are present in many extensions of the SM. In this lecture the author shall discuss some of the possibilities, focusing on processes that require muon beams. Other LFNV processes, such as the decays of the kaons and of the τ, provide complementary information. In the next Section he shall consider some sources of LFNV that do not require an extension of the gauge group of the SM (the added leptons or Higgs bosons may of course originate from models with extended gauge groups). In Section 3 he discusses LFNV in left-right symmetric models. In Section 4 he considers LFNV in supersymmetric models, first in R-parity conserving supersymmetric grand unified models, and then in the minimal supersymmetric standard model with R-parity violation. The last section is a brief summary of the author's conclusions

Work-family conflict is a complex, multi-dimensional construct. When families decide to continue their professional career, work and family role matching demands efforts and causes strain. Results of a qualitative research show that having and taking care of pre-school and primary-school age children is one of main conflict reasons. Child-care arrangements have an important impact on parents’ experiences of work and their career paths. Job tenure and involvement into work-team are lower stres...

Adoption studies were intended to separate genetic from environmental "causal" factors. In earlier adoption studies, psychiatric diagnostic labels for the adoptive parents were used as a proxy for the multiple dimensions of the family rearing environment. In the Finnish Adoption Study, research design provided the opportunity to study directly the adoptive family rearing environment. For this purpose 33 sub-scales were selected creating what we call Oulu Family Rating Scale (OPAS, Oulun PerheArviointiSkaala). In this paper, the manual for scoring of these sub-scales is presented.

Trends in popular belief about same-sex relationships have undergone noteworthy change in the United States over the last decade. Yet this change has been marked by stark polarizations and has occurred at varying rates depending upon regional, community, racial, religious, and individual family context. For queer youth and their families, this cultural transformation has broadened opportunities and created a new set of risks and vulnerabilities. At the same time, youth's increasingly open and playful gender fluidity and sexual identity is complicated by unique intersections of class, race, religion, and immigration. Effective family therapy with queer youth requires practitioner's and treatment models that are sensitive to those who bear the burden of multiple oppressions and the hidden resilience embedded in their layered identities. We present case examples of our model of family therapy which addresses refuge, supports difficult dialogs, and nurtures queerness by looking for hidden resilience in the unique intersections of queer youths' lives. These intersections provide transformational potential for youth, their families and even for family therapists as we are all nurtured and challenged to think more complexly about intersectionality, sexuality, and gender. © 2015 Family Process Institute.

Promotion of family planning in countries with high birth rates has the potential to reduce poverty and hunger and avert 32% of all maternal deaths and nearly 10% of childhood deaths. It would also contribute substantially to women's empowerment, achievement of universal primary schooling, and long-term environmental sustainability. In the past 40 years, family-planning programmes have played a major part in raising the prevalence of contraceptive practice from less than 10% to 60% and reducing fertility in developing countries from six to about three births per woman. However, in half the 75 larger low-income and lower-middle income countries (mainly in Africa), contraceptive practice remains low and fertility, population growth, and unmet need for family planning are high. The cross-cutting contribution to the achievement of the Millennium Development Goals makes greater investment in family planning in these countries compelling. Despite the size of this unfinished agenda, international funding and promotion of family planning has waned in the past decade. A revitalisation of the agenda is urgently needed. Historically, the USA has taken the lead but other governments or agencies are now needed as champions. Based on the sizeable experience of past decades, the key features of effective programmes are clearly established. Most governments of poor countries already have appropriate population and family-planning policies but are receiving too little international encouragement and funding to implement them with vigour. What is currently missing is political willingness to incorporate family planning into the development arena.

To distinguish families of Mutong correctly and direct effective and safe clinical administration. Comparison among families of Mutong on Herbs, Taxology, Clinic, Pharmacology and Toxicology. 1. There are mainly three families of Mutong: Lardizabalaceae, Ranunculaceae, Aristolochiaceae, which were all included in China Pharmacopeia in 1963. However only Mutong of Ranunculaceae and Aristolochiaceae family have been included in China Pharmacopeia since 1977, but Mutong of Lardizabalaceae family has not been included in China Pharmacopeia ever since. 2. It was Mutong of Lardizabalaceae family that was used mainly through the ages without toxic records, and Mutong of Aristolochiaceae e.g. Caulis Aristolochia manshuriensis (CAM) was not put down in writing of past ages but is mainly used today with toxicity repeatedly. 3. CAM contain aristolochic acid and aristololactam with high toxicity, which plays an uncertain role in diuresis with poor bactericidal power. Mutong of Lardizabalaceae family e.g. Akebia trifoliata (Thunb.) Koidz. var. australis (Diels) Rehd (ATKV) don't contain aristolochic acid and aristololactam, which has low toxicity and plays a certain role in diuresis with high bactericidal power. It may be quite safe to use ATKV instead of CAM in clinics. So we suggest that ATKV should be reused as first Mutong in China Pharmacopeia revised edition in order to ensure a correct understanding of the facts and reveal Mutong in its true colors, and CAM should be used as second Mutong strictly according to the rules in China Pharmacopeia revised edition.

This paper reports a familial amyloid polyneumpathy (FAP) family in China. This family being investigated had 69 members of five generations. From the third generation, there have been 16 patients. The age of onset was about 3 to 5 decades. The initial symptoms were autonomic nerve symptcans, such as impotence, dyspepaia and diarrhoea, associated with the sensory loss of lower extremities. As the disease progressed. the upper extremities and motor ability were also involved. The duration of disease course wasabout 8-10 years, most patients died of infection and cacbexia. Sural biopsy in 3 patients had showed positive Congo red staining. From the clinical view, this FAP family is similar to FAP I found in Japan. Thetrue classification, however, should be confirmed by further genetic analysis.

Cranial neuropathy is usually idiopathic and familial cases are uncommon. We describe a family with 5 members with cranial neuropathy over 3 generations. All affected patients were women, indicating an X-linked dominant or an autosomal dominant mode of inheritance. Our cases and a review of the literature suggest that familial idiopathic cranial neuropathy is a rare condition which may be related to autosomal dominant vascular disorders (e.g. vascular tortuosity, sclerosis, elongation or extension), small posterior cranial fossas, anatomical variations of the posterior circulation, hypersensitivity of cranial nerves and other abnormalities. Moreover, microvascular decompression is the treatment of choice because vascular compression is the main factor in the pathogenesis. To the best of our knowledge, this is the first report of familial cranial neuropathy in China.
Full Text Available Introduction comprises the information on two main forms of same sex families, civic partnership (same sex partnership and same sex marriage. Countries and various status modalities of legal regulations are mentioned. The main part of the text is dedicated to presentation of the findings of the most recent research on various aspects regarding children of same sex partnerships. It comprises presentations grouped in four main chapters: acceptance of same sex partnerships, acceptance of legal recognition of the same sex partnerships, family plans of homosexual teenagers, and raising children within and by the same sex partners. Also the real life cases mirroring legal changes through their life destinies are presented, such is e.g. the Irish way to legalization of the same sex partnerships. In addition, a love story of two women crowned by giving birth of their four children is mentioned. Reasons against and negative reactions the author puts under the title Homophobia. In the Concluding remarks, the author presents the most recent examples of legal changes happened in Norway, Ecuador, and in the American states of California and Connecticut. It was also stated that in European countries of low birth rate, the same sex families are inevitably identified as one of demographically valuable source of creating and raising children, which is worthy to be supported, rather than being hindered without reason and discriminated. Although different than a model of heterosexual family, same sex partnerships neither are harrowing to traditional family values, nor reflex of any kind of promiscuous, antisocial behavior, avoidance of parenthood, and negation of family. Quite opposite, these families are an outcome of endeavors of homosexuals not to be deprived of family, parenthood and all of other values of stabile, monogamous, emotional/sexual socially accepted and legally recognized and regulated conventional family. .

Parental empowerment signifies parents' sense of confidence in managing their children, interacting with services that their children use and improving child care services. High empowerment is associated with parents' resilience to demands and their confidence to make decisions and take actions that positively affect their families. Most families with children access various healthcare and education services. Professionals working in these services are therefore ideally placed to reinforce parental empowerment. However, little is known about the characteristics associated with parental empowerment within a generic sample of parents or in the context of basic child care services. The aim of this study was to assess how family characteristics are associated with maternal and paternal empowerment in the family, in service situations and in the service system. Parental empowerment was measured among 955 parents (mothers = 571; fathers = 384) of children aged 0-9 years using the Generic Family Empowerment Scale. Family characteristics were assessed through questions on children, parents and the life situation. Associations between empowerment and family characteristics were evaluated using one-way analysis of variance and t-test. Parental empowerment was predicted by multiple linear regression analysis. Parents' concerns related to their parenting, such as whether they possessed sufficient skills as a parent or losing their temper with children, as well as experiences of stress in everyday life, were negatively associated with all dimensions of maternal and paternal empowerment. Both determinants were more common and more significant in empowerment than child-related problems. Promoting parental self-confidence and providing appropriate emotional and concrete support for everyday functioning may reinforce parental empowerment, thereby enhancing families' well-being and coping, as well as improving their access to required services and timely support.

Family planning (FP) has been promoted in China through improvements in maternal and child health (MCH) which have affected people's attitude toward childbearing. A case study of FP in Taicang County of Jiangsu Province, China is given. Total population is 446,620; natural increase is 10/1000. 99% of births have been planned in recent years. Contraceptive prevalence has reached 92.71%. Contraceptive awareness has opened people up to health education in general. The community participates in management of human wastes, improvement of water supplies, and parasite control in rural areas. MCH was begun in the early 1980s with premarital examinations, prenatal examinations, postnatal visits, and physical checkups. A systematic program has established in 1983. A pilot program integrating FP, MCH, and parasite control operated between 1984 and 1986, in 7 townships was established and MCH was institutionalized. Increases occurred in comprehensive care for women from 49.1% in 1984 to 78.3% in 1986. Children's coverage rose from 78.2% to 85.9%. Perinatal mortality dropped from 30.2/1000 to 20.8/1000. Neonatal mortality declined from 21.3/1000 to 17.3/1000. Infant mortality also decreased from 31.6/1000 to 21.5/1000. Integration of programs throughout the county was achieved after 1987. 99% of women used the MCH handbook. Between 1987 and 1990, the perinatal, neonatal, and infant mortality rate dropped to 12.9/1000, 9.5/1000, and 14.7/1000, respectively. MCH achievements are attributed to a strengthening of the MCH network to improve access and improve MCH workers' level of professional skill, to the availability of premarriage and couples of reproductive age services and child care, and to the contribution of research. Careful monitoring during pregnancy helped reduce the incidence of difficult labors for high risk women from 17.55 in 1984 to 11-15% in recent years. 99.9% deliver in hospitals. There were no maternal deaths in 1989 or 1990. Neonatal tetanus has been

NMDA receptors, which regulate synaptic strength and are implicated in learning and memory, consist of several subtypes with distinct subunit compositions and functional properties. To enable spatiotemporally defined, rapid and reproducible manipulation of function of specific subtypes, we engineered a set of photoswitchable GluN subunits ('LiGluNs'). Photo-agonism of GluN2A or GluN2B elicits an excitatory drive to hippocampal neurons that can be shaped in time to mimic synaptic activation. Photo-agonism of GluN2A at single dendritic spines evokes spine-specific calcium elevation and expansion, the morphological correlate of LTP. Photo-antagonism of GluN2A alone, or in combination with photo-antagonism of GluN1a, reversibly blocks excitatory synaptic currents, prevents the induction of long-term potentiation and prevents spine expansion. In addition, photo-antagonism in vivo disrupts synaptic pruning of developing retino-tectal projections in larval zebrafish. By providing precise and rapidly reversible optical control of NMDA receptor subtypes, LiGluNs should help unravel the contribution of specific NMDA receptors to synaptic transmission, integration and plasticity.

Full Text Available Nowadays the understanding of the institute of marriage and its importance in the society has changed. Marriage is no longer assumed to be a commitment for a lifetime. As the principle of equality has replaced hierarchy as the guiding principle of family law it gave more grounds for family disputes and it became socially acceptable to leave marriages that are intolerable or merely unfulfilling. The aim of this article is to suggest an alternative dispute resolution method-mediation as a worthy option for resolving family conflicts.

We present a model for the unification of fermion families based on the gauge symmetry SO(15). It is a minimal SO(n) model which can accommodate the known fermions within a single irreducible representation. The model predicts four ordinary fermion families and four families of mirror fermions. The latter have V + A weak interactions, and their mass scale is predicted to be 10 2 GeV/c 2 . We argue that radiative corrections to the fermion masses can cause non-negligible mixing between ordinary and mirror fermions. The implications of these mixings for the weak interaction phenomenology and solar neutrinos are discussed. (orig.)
The results of a survey of 111 clinical psychologists in the Republic of Ireland along with some comparable data from US and UK surveys were used to address a series of questions about the link between family therapy and clinical psychology.

Prior research has demonstrated the benefits of family-supportive organization perceptions (FSOP) for reducing stress, increasing satisfaction, and increasing worker commitment; however, less research has studied health outcomes or possible differences in the effects of FSOP based on worker characteristics. The present study examined relationships between FSOP and health outcomes, as well as how those relationships may depend on work schedule and family differences. Using a sample of 330 acute care nurses, the findings indicated that FSOP predicted several health and well-being outcomes obtained 9 months later. Further, the relationships between FSOP and the outcome variables depended on some work schedule and family differences. In terms of family differences, FSOP was most strongly related to life satisfaction for those who cared for dependent adults. The relationship between FSOP and health outcomes of depression, musculoskeletal pain, and physical health symptoms were generally significant for workers with dependent children, but not significant for workers with no children. Regarding schedule differences, the relationship between FSOP and life satisfaction was significant for those on nonstandard (evening/night) shifts but not significant for standard day shift workers; however, there were no differences in FSOP relationships by number of hours worked per week. The findings demonstrate that FSOP may benefit some employees more than others. Such differences need to be incorporated into both future work-family theory development and into efforts to document the effectiveness of family-supportive policies, programs, and practices.

In this review, we examine the effects of family economic security policies (i.e., minimum wage, earned income tax credit, unemployment insurance, Temporary Assistance to Needy Families) on child and family health outcomes, summarize policy generosity across states in the USA, and discuss directions and possibilities for future research. This manuscript is an update to a review article that was published in 2014. Millions of Americans are affected by family economic security policies each year, many of whom are the most vulnerable in society. There is increasing evidence that these policies impact health outcomes and behaviors of adults and children. Further, research indicates that, overall, policies which are more restrictive are associated with poorer health behaviors and outcomes; however, the strength of the evidence differs across each of the four policies. There is significant diversity in state-level policies, and it is plausible that these policy variations are contributing to health disparities across and within states. Despite increasing evidence of the relationship between economic policies and health, there continues to be limited attention to this issue. State policy variations offer a valuable opportunity for scientists to conduct natural experiments and contribute to evidence linking social policy effects to family and child well-being. The mounting evidence will help to guide future research and policy making for evolving toward a more nurturing society for family and child health and well-being.

Full Text Available In Mexico, the arrangement of clinical practice has been influenced by a decision-making process that seeks to improve health indicators, thus transforming the patient into a number. Family medicine has been practiced within the limits of an institutional biomedical model where the health-disease process is approached from a biologist perspective. On the other hand, collective health understands this process as stemming from the collective sphere and includes social and biological perspectives, giving an important standing to society. Likewise, it puts policy as a determinant in bettering social health bringing together public policy with health matters. Family medicine must become the axis around which health needs are catered to, together with social conditioning factors that affect families and individuals. This leads to a trans-disciplinary approach to communities set free from a mere biomedical profile. In this context, collective health provides theoretical support to the upcoming debate on family medicine.

We have compared chromosome-specific genes in a set of 18 finished Vibrio genomes, and, in addition, also calculated the pan- and core-genomes from a data set of more than 250 draft Vibrio genome sequences. These genomes come from 9 known species and 2 unknown species. Within the finished...... chromosomes, we find a core set of 1269 encoded protein families for chromosome 1, and a core of 252 encoded protein families for chromosome 2. Many of these core proteins are also found in the draft genomes (although which chromosome they are located on is unknown.) Of the chromosome specific core protein...... families, 1169 and 153 are uniquely found in chromosomes 1 and 2, respectively. Gene ontology (GO) terms for each of the protein families were determined, and the different sets for each chromosome were compared. A total of 363 different "Molecular Function" GO categories were found for chromosome 1...

Many organizational change efforts don’t live up to their expectations, with inefficiencies in the interaction process between organizational actors as one of the main potential reasons for this failure. Therefore, this paper will focus on the impact of interaction processes on change within the specific organizational context of family firms. Family firms are particularly interesting for organizational change research since they have several unique characteristics that may facilitate or hind...
Full Text Available The aim of this paper is to review some approaches to family agriculture and the process of commercialization, as well as seek contemporary theoretical contributions to understand that form of social production with markets. It is a theoretical essay and as main conclusion it is highlighted the important contributions of the New Institutional Economics and New Economic Sociology, which, through the concepts of institutions and rooting, explain the relationship of family agriculture with markets.

Abstract Background Chemoreceptor proteins mediate the first step in the transduction of environmental chemical stimuli, defining the breadth of detection and conferring stimulus specificity. Animal genomes contain families of genes encoding chemoreceptors that mediate taste, olfaction, and pheromone responses. The size and diversity of these families reflect the biology of chemoperception in specific species. Results Based on manual curation and sequence comparisons among putative G-protein-...

Abstract In the United States, several states have made policy decisions regarding whether and how to use familial searching of the Combined DNA Index System (CODIS) database in criminal investigations. Familial searching pushes DNA typing beyond merely identifying individuals to detecting genetic relatedness, an application previously reserved for missing persons identifications and custody battles. The intentional search of CODIS for partial matches to an item of evidence offers law enforce...

This article is intended to describe the current hegemonic masculinity within the Roma family structure in the Czech Republic, with regard to changes related to developments in the majority society and the current socioeconomic situation of the Roma. The theoretical context of this article is based on the paradigm of masculine hegemony as it exists and has existed in the Roma families. Data for the study came from semi-structured interviews with 30 Roma females and 30 Roma males living as couples, in three Czech cities. The main finding reveals a dichotomy between the traditional roles of Roma women, i.e. care for the family and the household, and the present functions, i.e. contributing to the family income through social benefits. We observed a decline in the traditional role of Roma men, who were often unemployed. We related the change in the roles of men to the "non-functionality of the men", contributing to the emerging potential for emancipation of Roma women. However, the traditional patriarchal Roma family is structured such that men are given the main decision making powers, which has slowed changes in marginalized Roma families. Additionally, social pressures against women as well as socially conditioned pressures that act to preserve hegemonic masculinity, have largely prevented the realization of the potential for emancipation of Roma women, or if a woman tries to leave her non-functioning husband.

National medical organizations recommend that during prenatal counseling sessions, healthcare providers discuss how having a child with Down syndrome (DS) might impact the family unit. Few studies, to date, have surveyed families about their life experiences. For this investigation, we examined 41 family attitudes, which were obtained from mailed questionnaires completed by 1,961 parents/guardians, 761 brothers/sisters, and 283 people with DS who were members of six DS non-profit organizations, chosen for their size, ethnic/racial diversities, and geographic distribution throughout the United States. About 83% of families reported to all being proud of the family member with DS, and 87% reported to all feeling love for the member with DS. Younger siblings (ages 9-11) were more likely to feel embarrassed by their sibling with DS if their parents/guardians also did. If one or more parents/guardians felt that their children without DS did have a good relationship with their child with DS, siblings were more likely to report that they loved and liked their brother/sister with DS. Overall, our data demonstrate that positive themes tend to dominate within modern-day families who have members with DS, although challenges were not insignificant for some. © 2015 Wiley Periodicals, Inc.
Full Text Available There is considerable overlap between Le Play's mid-eighteenth-century household model map and the regional TFR map of central-southern Europe in the 1980s. The author examines the overall structure of relationships involved in Le Play's typology and observes that both the stem-family and the unstable family area in the Southern Europe are marked by a small, close-knit network of strong ties, with kinship predominance. Vice versa, the social support hinges upon a network of kin in the stem-family area, upon an alliance among different kindred units in the unstable Mediterranean area. All this leads to formulating a hypothesis of a tri-partite model for Western European relationship models. How can we explain the relationship between family predominance as anthropological embedding and family collapse as demographic reaction? The author reconsiders this question in the light of Festinger's cognitive dissonance theory and Elder's 'principle of accentuation': different, regionally rooted, family and kinship patterns "react" in contact with an appropriate reagent, such as the macro-process of modernisation, generating different patterns of today's demographic behaviour.
Full Text Available The paper presents an overview of research findings on influence of family environment, especially parental behaviour, on child's development. Contemporary authors question early socialization researchers' claims that family characteristics and parental behaviour have important influence on behaviour of their children. Later researchers examined the size and durability of possible effects of family environment on child development. In addition, they focused on establishing whether it is actually the parental behaviour that influences child's development or, on the contrary, parental behaviour represents mainly a reaction to child's characteristics. Behaviour genetic studies have provided evidence that many traditional measures of family environment, including measures of parental behaviour, show genetic influence, thus reflecting genetically influenced child characteristics. Behaviour geneticists also suggest that environmental influences on child (personality development include predominantly non-shared environment, i.e. individual child's specific experiences, his/her own perceptions and interpretations of objectively same events. Based on empirically determined significant genetic effects on most behavioural traits and inconclusive results of studies on effects of family environment on child development some authors believe that it is not the parents, but rather genetic factor and/or peers who have the key role in child development. With respect to findings of behaviour genetics numerous recent studies of relations between family environment and child development involve child specific measures of (extrafamilial environment and examine the interactions between characteristics of an individual and those of his/her environment.

To understand the family's experience of a child who uses a cochlear implant (CI). Specifically, to identify the difficulties, changes, and feelings entailed by deafness and the use of the CI; the coping strategies; and to understand the role of the family for the child with a CI. Qualitative research, using Symbolic Interactionism and Straussian Grounded Theory as the theoretical and methodological frameworks, respectively. Data collection instrument: semi-structured interview. A total of 9 families (32 individuals) participated in the study. The children's ages ranged from 6 to 11 years old (mean = 8.9 years old). Their experience is described in the following categories: Having to fight for results, Coping with difficult situations, Recognizing that you are not alone, Learning to overcome, and Having one's life restored by the implant. Cochlear implantation changes the direction of the child and the family's life by restoring the child's opportunity to hear and to obtain good results in her personal, social, and academic development. Even after implantation, the child continues to experience difficulties and requires the family's mobilization in order to be successful. The family is the principal actor in the process of the child's rehabilitation.

Family-centered rounds (FCR) are recommended as standard practice in the pediatric inpatient setting; however, limited data exist on best practices promoting family engagement during rounds. To identify strategies to enhance family engagement during FCR using a recognized systems engineering approach. In this qualitative study, stimulated recall interviews using video-recorded rounding sessions were conducted with participants representing the various stakeholders on rounds (15 parents/children and 22 healthcare team [HCT] members) from 4 inpatient services at a children's hospital in Wisconsin. On video review, participants were asked to provide strategies that would increase family engagement on FCR. Qualitative content analysis of interview transcripts was performed in an iterative process. We identified 21 categories of strategies corresponding to 2 themes related to the structure and process of FCR. Strategies related to the structure of FCR were associated with all five recognized work system elements: people (HCT composition), tasks (HCT roles), organization (scheduling of rounds and HCT training), environment (location of rounds and HCT positioning), and tools and technologies (computer use). Strategies related to the FCR process were associated with three rounding phases: before (HCT and family preparation), during (eg, introductions, presentation content, communication style), and after (follow-up) FCR. We identified a range of strategies to enhance family engagement during FCR. These strategies both confirm prior work on the importance of the content and style of communication on rounds and highlight other factors within the hospital work system, like scheduling and computer use, which may affect family engagement in care.

We have found in our clinic a 28.1% prevalence of familial chondrocalcinosis among 149 family members of 32 patients with calcium pyrophosphate dihydrate deposition disease. The clinical and radiological characteristics of these familial chondrocalcinosis patients were similar to those of the Chiloes with familial chondrocalcinosis previously reported. No significant clinical or radiological differences were detected between our sporadic and familial chondrocalcinosis patients. Our findings support the hypothesis that the Chiloes familial chondrocalcinosis was carried to Chile by Spanish immigrants.
