BACKGROUND: Many dementia and cardiovascular disease (CVD) cases in older adults are attributable to modifiable vascular and lifestyle-related risk factors, providing opportunities for prevention. In the Healthy Aging Through Internet Counselling in the Elderly (HATICE) randomized controlled trial, an internet-based multidomain intervention is being tested to improve the cardiovascular risk (CVR) profile of older adults. OBJECTIVE: To design a multidomain intervention to improve CVR, based on the guidelines for CVR management, and administered through a coach-supported, interactive, platform to over 2500 community-dwellers aged 65+ in three European countries...

Spontaneous tumors regression has been associated with microbial infection for 100s of years and inspired the use of bacteria for anticancer therapy. Dr. William B. Coley (1862-1936), a bone- sarcoma surgeon, was a pioneer in treating his patients with both live bacterial-based and mixture of heat-killed bacteria known as "Coley's toxins." Unfortunately, Coley was forced to stop his work which interrupted this field for about half a century. Currently, several species of bacteria are being developed against cancer...

The immune system and the kidneys are closely linked. In health the kidneys contribute to immune homeostasis, while components of the immune system mediate many acute forms of renal disease and play a central role in progression of chronic kidney disease. A dysregulated immune system can have either direct or indirect renal effects. Direct immune-mediated kidney diseases are usually a consequence of autoantibodies directed against a constituent renal antigen, such as collagen IV in anti-glomerular basement membrane disease...

Dendritic cell (DC)-mediated T cell tolerance deficiencies contribute to the pathogenesis of autoimmune diseases such as type 1 diabetes. Delivering self-antigen to dendritic-cell inhibitory receptor-2 (DCIR2) + DCs can delay but not completely block diabetes development in NOD mice. These DCIR2-targeting antibodies induce tolerance via deletion and anergy, but do not increase islet-specific Tregs. Because low-dose IL-2 (LD-IL-2) administration can preferentially expand Tregs, we tested whether delivering islet-antigen to tolerogenic DCIR2 + DCs along with LD-IL-2 would boost islet-specific Tregs and further block autoimmunity...

The need for species identification and taxonomic discovery has led to the development of innovative technologies for large-scale plant identification. DNA barcoding has been useful, but fails to distinguish among many species in species-rich plant genera, particularly in tropical regions. Here, we show that chemical fingerprinting, or 'chemocoding', has great potential for plant identification in challenging tropical biomes. Using untargeted metabolomics in combination with multivariate analysis, we constructed species-level fingerprints, which we define as chemocoding...

A microfluidic platform combined with a deterministic model accounting for surface ligands reveals new insights into the nanocrystal formation process. The comparison of on-line kinetic information with model predictions enables the derivation of temperature-dependent kinetic parameters for the CdSe model system. This fully generalizable approach represents a step forward toward a quantitative prediction of the nanocrystal size distribu-tion, enabling the control and optimization of process performance and material properties...

We summarize work on a speciose Neotropical tree genus, Inga (Fabaceae), examining how interspecific variation in anti-herbivore defenses may have evolved, how defenses shape host choice by herbivores and how they might regulate community composition and influence species radiations. Defenses of expanding leaves include secondary metabolites, extrafloral nectaries, rapid leaf expansion, trichomes, and synchrony and timing of leaf production. These six classes of defenses are orthogonal, supporting independent evolutionary trajectories...

William Coley, between 1895 and 1936, treated hundreds of cancer patients using infusions of fever inducing bacerial extracts. Similar experiments were done by Klyuyeva and co-workers in the 1940ies in Russia using trypanosoma extracts. Many remissions and cures were reported. We have conjectured that pathogen associated molecular pattern substances (PAMP) are the molecular explanation for the beneficial treatments in both groups. We could show that a combination of PAMP can eradicate solid tumours in cancer mice if applied several times...

Defining the primary cognitive endpoint is a major decision for Alzheimer's disease preventive trials. As an example for further trials we present in detail the three-year cognitive decline in the placebo group of MAPT trial, a randomized controlled trial (RCT) using a cognitive composite score (MAPT-PACC). Participants were dementia-free adults 70 years or older, with subjective memory complaints. Our findings as expected showed subjects with older age (>75), higher beta amyloid brain deposition, APOE-ε4 allele carriers, with low RBC DHA+EPA levels and higher CDR level are at higher risk of cognitive decline...

The current study examined child maltreatment re-offending in United States Air Force (USAF) families. In a clinical database containing 24,999 child maltreatment incidents perpetrated by 15,042 offenders between the years 1997 and 2013, 13% of offenders maltreated a child on more than one date (i.e., they re-offended). We explored several offender demographic characteristics associated with who re-offended and found that civilians re-offended at a similar rate as active duty members, males re-offended at a similar rate as females, and younger offenders were more likely to re-offend than older offenders...

The Beyond Ultrasound First Forum was conceived to increase awareness that the quality of obstetric and gynecologic ultrasound can be improved, and is inconsistent throughout the country, likely due to multiple factors, including the lack of a standardized curriculum and competency assessment in ultrasound teaching. The forum brought together representatives from many professional associations; the imaging community including radiology, obstetrics and gynecology, and emergency medicine among others; in addition to government agencies, insurers, industry, and others with common interest in obstetric and gynecologic ultrasound...

We demonstrate molecular similarity to be a surprisingly effective metric for proposing and ranking one-step retrosynthetic disconnections based on analogy to precedent reactions. The developed approach mimics the retrosynthetic strategy defined implicitly by a corpus of known reactions without the need to encode any chemical knowledge. Using 40 000 reactions from the patent literature as a knowledge base, the recorded reactants are among the top 10 proposed precursors in 74.1% of 5000 test reactions, providing strong quantitative support for our methodology...

BACKGROUND: Although bariatric procedures are commonly performed in clinical practice, long-term data on the comparative effectiveness and safety of different procedures on sustained weight loss, comorbidities, and adverse effects are limited, especially in important patient subgroups (eg, individuals with diabetes, older patients, adolescents, and minority patients). OBJECTIVE: The objective of this study was to create a population-based cohort of patients who underwent 3 commonly performed bariatric procedures-adjustable gastric band (AGB), Roux-en-Y gastric bypass (RYGB), and sleeve gastrectomy (SG)-to examine the long-term comparative effectiveness and safety of these procedures in both adults and adolescents...

INTRODUCTION: African American mothers and other mothers of historically underserved populations consistently have higher rates of adverse birth outcomes than White mothers. Increasing prenatal care use among these mothers may reduce these disparities. Most prenatal care research focuses on prenatal care adequacy rather than concepts of quality. Even less research examines the dual perspectives of African American mothers and prenatal care providers. In this qualitative study, we compared perceptions of prenatal care quality between African American and mixed race mothers and prenatal care providers...

OBJECTIVES: Elevated total plasma homocysteine is a risk factor for Alzheimer's disease (AD) and there is some evidence that omega-3 polyunsaturated fatty acids (n-3 PUFAs) can modulate the effects of homocysteine-lowering B vitamins on AD related pathologies. Hence we investigated the relationship between total plasma homocysteine and cortical β-amyloid (Aβ) in older adults at risk of dementia. The role of erythrocyte membrane n-3 PUFAs (omega 3 index) on this relationship was also explored...

The molecular components of the postsynaptic density (PSD) in excitatory synapses of the brain are currently being investigated as one of the major etiologies of neurodevelopmental disorders such as schizophrenia (SCZ) and autism. Postsynaptic density protein-95 (PSD-95) is a major regulator of synaptic maturation by interacting, stabilizing and trafficking N-methyl-d-aspartic acid receptors (NMDARs) and α-amino-3-hydroxy-5-methyl-4-isox-azoleproprionic acid receptors (AMPARs) to the postsynaptic membrane...

Fatigue is a common symptom in the elderly and has also been associated with impaired cognition in older adults. Hence, we sought to explore the cross-sectional relationship between fatigue and cerebral β-amyloid (Aβ) in 269 elderly individuals reporting subjective memory complaints from the Multidomain Alzheimer Preventive Trial. Standard uptake value ratios (SUVRs) were generated by [18 F] florbetapir positron emission tomography (PET) using the cerebellum as a reference. Cortical-to-cerebellar SUVRs (cortical-SUVRs) were obtained using the mean signal from the frontal cortex, temporal cortex, parietal cortex, precuneus, anterior cingulate, and posterior cingulate...

Oscillatory flow reactors provide a surface energy-driven approach for automatically screening reaction conditions and studying reaction mechanisms of bi-phasic nanocrystal ligand exchange reactions. Sulfide and cysteine ligand exchange reactions with as-synthesized CdSe quantum dots (QDs) are chosen as two model reactions. Different reaction variables including the new-ligand-to-QD ratio, the size of the particles, and the original ligand type are examined systematically. Based on the in-situ obtained UV-Vis absorption spectra during the reaction, we propose two different exchange pathways for the sulfide exchange reaction...
