Longxuetongluo Capsule (LTC), which is derived from the total phenolic extract of Chinese dragon's blood, has been proved to be safe as well as effective towards ischemic stroke. However, the effective material basis remains unclear. The present study thereby focused on the clarification of the qualitative and quantitative properties for the phenolic derivatives in LTC. Regarding homolog-focused chemical profiling, the mass fragmentation patterns of the primary subtypes of phenolic compounds such as homoisoflavanones, flavanes, chalcones, and flavonoid oligomers were summarized by assaying authentic references with hybrid ion trap time-of-flight mass spectrometry, and the chemical structures of 124 phenolic compounds, in total, were unambiguously or tentatively annotated in LTC by matching the accurate mass spectral profiles with the proposed mass cracking rules and those reference substances...

Sociological debates on youth engagement with electoral politics play out against a backdrop of supposed 'decline' in civic participation (e.g. Putnam , Norris, ), in turn contextualized by theories of individualization in 'late' or 'reflexive' modernity (Beck, Giddens). However, the enfranchisement of 16 and 17 year olds in the 2014 Scottish Independence Referendum catalysed remarkably high levels of voter turnout among this youngest group, and was accompanied by apparently ongoing political engagement. We explored this engagement among a strategic sample of young 'Yes' voters, in the immediate aftermath of this exceptional political event...

BACKGROUND: Food insecurity contributes to poor health outcomes among people living with HIV. In Latin America and the Caribbean, structural factors such as poverty, stigma, and inequality disproportionately affect women and may fuel both the HIV epidemic and food insecurity. METHODS: We examined factors contributing to food insecurity among women living with HIV (WLHIV) in the Dominican Republic (DR). Data collection included in-depth, semi-structured interviews in 2013 with 30 WLHIV with indications of food insecurity who resided in urban or peri-urban areas and were recruited from local HIV clinics...

BACKGROUND: Research has shown that the modes of leadership and management may influence health outcomes. However, majority of health leaders and managers in many low-income countries are promoted on account of clinical expertise. It has been recognised that these new managers are often ill-prepared for managing complex health systems. In response to this challenge, the Zambian Ministry of Health (MoH) has developed the Governance and Management Capacity Building (GMCB) Strategic Plan (2012-2016), whose overarching goal is to improve health sector governance and create an environment that is result-oriented, accountable and transparent...

Haruo Hosoya, Aapo Hyvärinen
Experimental studies have revealed evidence of both parts-based and holistic representations of objects and faces in the primate visual system. However, it is still a mystery how such seemingly contradictory types of processing can coexist within a single system. Here, we propose a novel theory called mixture of sparse coding models, inspired by the formation of category-specific subregions in the inferotemporal (IT) cortex. We developed a hierarchical network that constructed a mixture of two sparse coding submodels on top of a simple Gabor analysis...

By providing care for loved ones in the home, family caregivers save millions of dollars for our overtaxed healthcare system. Support groups can lighten the psychological burden of caregiving. Nonprofessionally facilitated (or peer) online caregiver support groups can help meet a critical need in healthcare as a low-cost resource for caregivers. Online caregiver peer support groups can promote the health and well-being of family caregivers and, by extension, the patients themselves, resulting in cost-savings for society...

The purpose of this study was to explore factors associated with the use of research evidence in Canadian National Sport Organisations (NSOs). Data were collected via individual semi-structured interviews with 21 representatives from Canadian NSOs. A qualitative description approach was used. Interviews were transcribed verbatim and subjected to an inductive-to-deductive thematic analysis. A research implementation framework (Rycroft-Malone, 2004) was used to organise inductively derived themes into the higher-order categories of evidence (use of evidence, disconnection between research and practice), context (lack of capacity, organisational structure), and facilitation (personal connections with researchers and sport scientists, formal meetings with stakeholders)...

The effect of addition of Curcumin on the adsorption and transport characteristics of a cationic dye, (LDS+), across negatively charged bilayers composed of POPG and DPPG lipids were investigated by the interface selective Second Harmonic (SH) spectroscopic technique. Curcumin induced changes in the SH electric field signal of the LDS+ ions (E2ω (LDS+)) were observed to depend critically on the bilayer acyl chain saturation/un-saturation ratio (S/U). Following earlier works, the increase in the E2ω (LDS+) signal is attributed to the release of the Na+ counter-ions present in the head-group region of the bilayer by Curcumin and the decay of the E2ω (LDS+) signal is attributed to the bilayer intercalated state of Curcumin...

Cells can sense and respond to changes in the topographical, chemical, and mechanical information in their environment. Engineered substrates are increasingly being developed that exploit these physical attributes to direct cell responses (most notably mesenchymal stem cells) and therefore control cell behavior toward desired applications. However, there are very few methods available for robust and accurate modeling that can predict cell behavior prior to experimental evaluations and this typically means that many cell test iterations are needed to identify best material features...

BACKGROUND: Besides the expected warm and joyful thoughts, a new mother can be disturbed by sudden frightening thoughts or images of harm done to her baby: harming intrusions, an obsessive phenomenon. Its high prevalence and possible consequences in functioning and in mother-child bonding makes it desirable that clinicians are well informed regarding the current state of knowledge about harming intrusions. OBJECTIVE: To provide a comprehensive review of all studies that have investigated harming intrusions in postpartum women...
