BACKGROUND: Family planning research has not adequately addressed women's preferences for different contraceptive methods and whether women's contraceptive experiences match their preferences. METHODS: Data were drawn from the Women's Healthcare Experiences and Preferences Study, an Internet survey of 1,078 women aged 18-55 randomly sampled from a national probability panel. Survey items assessed women's preferences for contraceptive methods, match between methods preferred and used, and perceived reasons for mismatch...

The brain can reproduce memories from partial data; this ability is critical for memory recall. The process of memory recall has been studied using autoassociative networks such as the Hopfield model. This kind of model reliably converges to stored patterns that contain the memory. However, it is unclear how the behavior is controlled by the brain so that after convergence to one configuration, it can proceed with recognition of another one. In the Hopfield model, this happens only through unrealistic changes of an effective global temperature that destabilizes all stored configurations...

The application of membrane adsorbers instead of classical packed bed columns for protein fractionation is still a growing field. In the case of egg white protein fractionation, the application of classical chromatography is additionally limited due to its high viscosity that impairs filtration. By using tangential flow membrane adsorbers as stationary phase this limiting factor can be left out, as they can be loaded with particle containing substrates. The flow conditions existing in tangential flow membrane adsorbers are not fully understood yet...

OBJECTIVE: To assess multiple dimensions of long-acting reversible contraception (LARC) knowledge and perceived multi-level barriers to LARC use among a sample of college women. STUDY DESIGN: We conducted an Internet-based study of 1982 female undergraduates at a large mid-western university. Our 55-item survey used a multi-level framework to measure young women's understanding of, experiences with intrauterine devices (IUD) and implants and their perceived barriers to LARC at individual, health systems and community levels...

The characteristics of neural network activity depend on intrinsic neural properties and synaptic connectivity in the network. In brain networks, both of these properties are critically affected by the type and levels of neuromodulators present. The expression of many of the most powerful neuromodulators, including acetylcholine (ACh), varies tonically and phasically with behavioural state, leading to dynamic, heterogeneous changes in intrinsic neural properties and synaptic connectivity properties. Namely, ACh significantly alters neural firing properties as measured by the phase response curve in a manner that has been shown to alter the propensity for network synchronization...

BACKGROUND: Educational interventions may be a strategy to increase human papillomavirus (HPV) vaccination among female university students, but studies to date have shown mixed results. This study evaluated the effect of MeFirst, an individually tailored, online educational intervention, on HPV vaccine-related knowledge, vaccination intention, and uptake among previously unvaccinated female university students. METHODS: All female students aged 18-26 years who reported being unvaccinated against HPV at a midwestern university were invited via email to enroll...

BACKGROUND: The aim of this paper was to determine the effects of using intermittent hand cooling during high intensity, intermittent training on thermoregulatory, performance and psychophysical variables in elite level swimmers in a training pool (30.5±0.5 °C). METHODS: Randomized cross-over design. Following a standard warm-up, ten male swimmers (20.3±3.2 years) were instructed to maintain the fastest 100-m time (on average) for an 8 x 100 m freestyle swimming set performed either in a training pool with cooling (TPC) or a training pool with no-cooling (TPNC)...

Acetylcholine (ACh) is a regulator of neural excitability and one of the neurochemical substrates of sleep. Amongst the cellular effects induced by cholinergic modulation are a reduction in spike-frequency adaptation (SFA) and a shift in the phase response curve (PRC). We demonstrate in a biophysical model how changes in neural excitability and network structure interact to create three distinct functional regimes: localized asynchronous, traveling asynchronous, and traveling synchronous. Our results qualitatively match those observed experimentally...

BACKGROUND: Notably absent from research and public and policy dialogue on the Affordable Care Act (ACA) and reproductive health care are women's perspectives and a broader understanding of factors that shape ACA attitudes. We investigated social, reproductive, and attitudinal factors associated with women's disagreement with the passage of the ACA. METHODS: Data were drawn from the Women's Health Care Experiences and Preferences Study, our population-based internet survey of 1,078 randomly sampled United States women ages 18-55 years conducted in September 2013...

OBJECTIVE: We characterized US women's preferred and usual sources of reproductive health care. STUDY DESIGN: Data were drawn from the Women's Health Care Experiences and Preferences Study, an Internet survey of 1078 women aged 18-55 years randomly sampled from a national probability panel. We described and compared women's preferred and usual sources of care (women's health specialists including obstetricians-gynecologists and family-planning clinics, primary care, other) for Papanicolaou/pelvic examination, contraception, and sexually transmitted infection (STI) services using χ(2), logistic regression, and kappa statistics...

INTRODUCTION: It is unclear how the Patient Protection and Affordable Care Act (ACA) will influence women's use of reproductive health care sources, including family planning clinics, which have traditionally played a key role in safety net services. We explored women's intended sources of care for contraception, pelvic exam/Pap test, and sexually transmitted infection (STI) testing services following passage of the ACA. METHODS: Data were drawn from a study of U...

We study the synchronization of neuronal networks with dynamical heterogeneity, showing that network structures with the same propensity for synchronization (as quantified by master stability function analysis) may develop dramatically different synchronization properties when heterogeneity is introduced with respect to neuronal excitability type. Specifically, we investigate networks composed of neurons with different types of phase response curves (PRCs), which characterize how oscillating neurons respond to excitatory perturbations...

Understanding spontaneous transitions between dynamical modes in a network is of significant importance. These transitions may separate pathological and normal functions of the brain. In this paper, we develop a set of measures that, based on spatio-temporal features of network activity, predict autonomous network transitions from asynchronous to synchronous dynamics under various conditions. These metrics quantify spike-timing distributions within a narrow time window as a function of the relative location of the active neurons...

Understanding the mechanisms underlying distributed pattern formation in brain networks and its content driven dynamical segmentation is an area of intense study. We investigate a theoretical mechanism for selective activation of diverse neural populations that is based on dynamically shifting cellular resonances in functionally or structurally coupled networks. We specifically show that sub-threshold neuronal depolarization from synaptic coupling or external input can shift neurons into and out of resonance with specific bands of existing extracellular oscillations, and this can act as a dynamic readout mechanism during information storage and retrieval...

Our population-based survey of 1078 randomly sampled US women, aged 18 to 55 years, sought to characterize their understanding of and attitudes toward the Affordable Care Act (ACA). Most women, especially socially disadvantaged groups, had negative or uncertain attitudes toward the ACA and limited understanding of its health benefits, including its relevance for their own health service coverage and utilization. Our findings are important for continued research, policy, and practice, with implications for whether, when, and how improved coverage will translate to improved access and outcomes for US women...

Many networks are embedded in physical space and often interact with it. This interaction can be exemplified through constraints exerted on network topology, or through interactions of processes defined on a network with those that are linked to the space that the network is embedded within, leading to complex dynamics. Here we discuss an example of such an interaction in which a signaling agent is actively transported through the network edges and, at the same time, spreads passively through space due to diffusion...

A period of sleep over the first few hours following single-trial contextual fear conditioning (CFC) is essential for hippocampally-mediated memory consolidation. Recent studies have uncovered intracellular mechanisms required for memory formation which are affected by post-conditioning sleep and sleep deprivation. However, almost nothing is known about the circuit-level activity changes during sleep that underlie activation of these intracellular pathways. Here we continuously recorded from the CA1 region of freely-behaving mice to characterize neuronal and network activity changes occurring during active memory consolidation...

OBJECTIVE: To assess differences in receipt of prescription contraception among women with and without chronic medical conditions. METHODS: This observational study used 3 years of administrative claims records for insured women aged 21-45 years who were enrolled in a commercial insurance company in Michigan between 2004 and 2009. Women were considered to have a chronic medical condition if they had at least two claims for one of the following conditions, in order of prevalence in our study population: hypertension, asthma, hypothyroidism, diabetes, obesity, rheumatoid arthritis, inflammatory bowel disease, or systemic lupus erythematosus...
