BACKGROUND: Cardiac resynchronization therapy (CRT) in chronic heart failure has been shown to improve mortality and morbidity. However, comprehensive data are not available as concerns how circulating biomarkers reflecting different organ functions, such as serum uric acid, blood urea nitrogen (BUN), albumin, cholesterol, or various liver enzymes, change over time as a consequence of CRT. The aim of this prospective study was to overview these possible changes. METHODS: A total of 20 routine laboratory parameters were measured in 122 control subjects and in 129 patients with chronic heart failure before CRT, 6 months, and 2 years later...

Microglia play a pivotal role in the maintenance of brain homeostasis but lose homeostatic function during neurodegenerative disorders. We identified a specific apolipoprotein E (APOE)-dependent molecular signature in microglia from models of amyotrophic lateral sclerosis (ALS), multiple sclerosis (MS), and Alzheimer's disease (AD) and in microglia surrounding neuritic β-amyloid (Aβ)-plaques in the brains of people with AD. The APOE pathway mediated a switch from a homeostatic to a neurodegenerative microglia phenotype after phagocytosis of apoptotic neurons...

INTRODUCTION: Inertial measurement units (IMUs) positioned on various body locations allow detailed gait analysis even under unconstrained conditions. From a medical perspective, the assessment of vulnerable populations is of particular relevance, especially in the daily-life environment. Gait analysis algorithms need thorough validation, as many chronic diseases show specific and even unique gait patterns. The aim of this study was therefore to validate an acceleration-based step detection algorithm for patients with Parkinson's disease (PD) and older adults in both a lab-based and home-like environment...

Excessive reactive oxygen species (ROS) can damage proteins, lipids, and DNA, which result in cell damage and death. The outcomes can be acute, as seen in stroke, or more chronic as observed in age-related diseases such as Parkinson's disease. Here we investigate the antioxidant ability of a novel synthetic flavonoid, Proxison (7-decyl-3-hydroxy-2-(3,4,5-trihydroxyphenyl)-4-chromenone), using a range of in vitro and in vivo approaches. We show that, while it has radical scavenging ability on par with other flavonoids in a cell-free system, Proxison is orders of magnitude more potent than natural flavonoids at protecting neural cells against oxidative stress and is capable of rescuing damaged cells...

Melanoma cells share many biological properties with neural crest stem cells. Here we show that the homeodomain transcription factor Msh homeobox 1 (MSX1), which is significantly correlated with melanoma disease progression, reprograms melanocytes and melanoma cells towards a neural crest precursor-like state. MSX1-reprogrammed normal human melanocytes express the neural crest marker p75 and become multipotent. MSX1 induces a phenotypic switch in melanoma, which is characterized by an oncogenic transition from an E-cadherin-high non-migratory state towards a ZEB1-high invasive state...

The purpose of this study was to examine the effects of focus of attention cues on movement coordination and coordination variability in the lower extremity. Twenty participants performed the standing long jump under both internal and external focus of attention conditions. A modified vector coding technique was used to evaluate the influence of attentional focus cues on lower extremity coordination patterns and coordination variability during the jumps. Participants jumped significantly further under an external focus of attention condition compared with an internal focus of attention condition (p = ...

BACKGROUND/OBJECTIVES: Breastfeeding may protect against excessive weight gain during infancy. However, the breast milk components responsible for this effect are unknown. We examined the variation of three breast milk hormones (adiponectin, leptin and insulin) according to maternal characteristics and determined their association with infant body composition. SUBJECTS/METHODS: We studied a representative subset of 430 breastfed infants in the CHILD birth cohort...

PURPOSE: In March 2013, regulatory warnings concerning the potential risks of domperidone caused considerable media attention in the Netherlands. The aim of the study was to assess the effect of regulatory warnings and the resulting media hype on the frequency of electrocardiogram (ECG) monitoring of inpatients using domperidone. We also studied the effect on the frequency of prescribing domperidone by physicians. METHODS: A 2-centre, observational, retrospective cohort study was performed...

B cell receptor (BCR) signaling is key for survival of chronic lymphocytic leukemia (CLL) cells, and BCR signaling inhibitors are clinically active. However, relapse and resistance to treatment require novel treatment options. In order to detect novel candidate therapeutic targets, we performed a genome-wide DNA methylation screen with custom arrays and identified aberrant promoter DNA methylation in 2192 genes. The transcription factor NFATC1 that is a downstream effector of BCR signaling was among the top hypomethylated genes and was concomitantly transcriptionally upregulated in CLL...

Chordoma is a rare tumor of notochordal origin, currently principally treated by surgery and/or irradiation. Here, we describe the clinical outcome of 3 consecutive patients with metastatic and locally advanced chordoma, treated with different immunotherapeutic approaches. All patients presented fast growing tumors and failure of standard therapies. One was treated with a tumor-based vaccine, the 2 others with anti-PD1 antibodies, all with impressive clinical and radiological responses. We therefore propose that chordoma is an immunogenic tumor and thus that translational and clinical research is necessary to develop rationally designed immunotherapy approaches...

Synthetic modification of cyclosporin A at P3-P4 positions led to the discovery of NIM258, a next generation cyclophilin inhibitor with excellent anti-hepatitis C virus potency, with decreased transporter inhibition, and pharmacokinetics suitable for coadministration with other drugs. Herein is disclosed the evolution of the synthetic strategy to from the original medicinal chemistry route, designed for late diversification, to a convergent and robust development synthesis. The chiral centers in the P4 fragment were constructed by an asymmetric chelated Claisen rearrangement in the presence of quinidine as the chiral ligand...

The familiarity effect (FE) refers to the phenomenon that it is easier to find an unfamiliar element on a background of familiar elements than vice versa. In this study, we examined the FE in texture segmentation while recording event-related brain potentials with the aim to find out which processing stages were influenced by familiarity. In two experiments, with different levels of texture homogeneity, the N1, the N2p and the P3 components were investigated. It was found that the FE in texture segmentation is associated with a modulation of the early N1 and of the intermediate N2p component for homogeneous textures...

REVIEW
Rupert Langer, Karen Becker
Neoadjuvant therapy has been successfully introduced in the treatment of locally advanced gastrointestinal malignancies, particularly esophageal, gastric, and rectal cancers. The effects of preoperative chemo- or radiochemotherapy can be determined by histopathological investigation of the resection specimen following this treatment. Frequent histological findings after neoadjuvant therapy include various amounts of residual tumor, inflammation, resorptive changes with infiltrates of foamy histiocytes, foreign body reactions, and scarry fibrosis...

The study goal was to examine the links of parent knowledge of children's behavior to diabetes outcomes and to test a mediational model that focused on psychological distress and self-care behavior. We recruited 132 adolescents (average age 12) and followed them to average age 23. At age 23 (n = 107), we conducted in-person interviews with these emerging adults to measure parent knowledge, psychological distress, self-care behavior and glycemic control. We used structural equation modeling to test our hypotheses with these cross-sectional data...

Positive and negative feedback learning is essential to optimize behavioral performance. We used the two-way active avoidance (TWA) task as an experimental paradigm for negative feedback learning with the aim to test the hypothesis that neuronal ensembles activate the activity-regulated cytoskeletal (Arc/Arg3.1) protein during different phases of avoidance learning and during retrieval. A variety of studies in humans and other animals revealed that the ability of aversive feedback learning emerges postnatally...

A 54-year old female, retired due to progressive cognitive decline, was diagnosed with early-onset Alzheimer's dementia. Conventional medication therapy for dementia had proven futile. Initial evaluation revealed a non-verbal female seated in a wheelchair, dependent on 2-person assist for all transfers and activities of daily living (ADLs.) She had been either non-responsive or actively resistive for both ADLs and transfers in the 6 months prior to assessment. Following a total of 17 one hour therapy sessions over 19 weeks in a warm water therapy pool, she achieved ability to tread water for 15 minutes, transfers improved to moderate to-maximum assist from seated, ambulation improved to 1000' with minimum-to-moderate assist of 2 persons...

Dysfunction of the central nervous system (CNS) in neurodegenerative diseases or after brain lesions seriously affects life quality of a growing number of elderly, since the adult CNS lacks the capacity to replace or repair damaged neurons. Despite intensive research efforts, full functional recovery after CNS disease and/or injury remains challenging, especially in an aging environment. As such, there is a rising need for an aging model in which the impact of aging on successful regeneration can be studied...
