A small uncharged cyclopeptide scaffold inspired by a natural product and designed to undergo postfunctionalizations was used as a new transmembrane vector. A bioactive and fluorescent triazole aminocoumarin was bound to this carrier to facilitate its moving across cell and subcellular membranes, and this led to an increase in its cell toxicity.

REVIEW
Gádor-Indra Hidalgo, María Pilar Almajano
Red fruits, as rich antioxidant foods, have gained over recent years capital importance for consumers and manufacturers. The industrial extraction of the phenolic molecules from this source has been taking place with the conventional solvent extraction method. New non-conventional extraction methods have been devised as environmentally friendly alternatives to the former method, such as ultrasound, microwave, and pressure assisted extractions. The aim of this review is to compile the results of recent studies using different extraction methodologies, identify the red fruits with higher antioxidant activity, and give a global overview of the research trends regarding this topic...

Transport measurements in inverted InAs/GaSb quantum wells reveal a giant spin-orbit splitting of the energy bands close to the hybridization gap. The splitting results from the interplay of electron-hole mixing and spin-orbit coupling, and can exceed the hybridization gap. We experimentally investigate the band splitting as a function of top gate voltage for both electronlike and holelike states. Unlike conventional, noninverted two-dimensional electron gases, the Fermi energy in InAs/GaSb can cross a single spin-resolved band, resulting in full spin-orbit polarization...

This report aims to augment what is already known about emotional distress in Type 2 diabetes, by assessing the predictive value of illness perception clusters and relationship quality on four subcategories of Diabetes Distress.162 individuals with Type 2 diabetes responded to a postal questionnaire assessing demographics, depression, diabetes distress, illness perceptions and relationship quality. Long-term blood glucose was retrieved from participants' General Practitioner. Three illness perception clusters emerged from the data, capturing three subgroups of participants sharing similar illness perception schemas...

In Europe extracts from Viscum album L., the European white-berry mistletoe, are widely used as a complementary cancer therapy. Viscumins (mistletoe lectins, ML) have been scrutinized as important active components of mistletoe and exhibit a variety of anticancer effects such as stimulation of the immune system, induction of cytotoxicity, reduction of tumor cell motility as well as changes in the expression of genes associated with cancer development and progression. By microarray expression analysis, quantitative RT-PCR and RT-PCR based validation of microarray data we demonstrate for the Viscum album extract Iscador Qu and for the lectins Aviscumine and ML-1 that in glioma cells these drugs differentially modulate the expression of genes involved in the regulation of cell migration and invasion, including processes modulating cell architecture and cell adhesion...

Foreign and self-cytoplasmic DNA are recognized by numerous DNA sensor molecules leading to the production of type I interferons. Such DNA agonists should be degraded otherwise cells would be chronically stressed. Most human APOBEC3 cytidine deaminases can initiate catabolism of cytoplasmic mitochondrial DNA. Using the human myeloid cell line THP-1 with an interferon inducible APOBEC3A gene, we show that cytoplasmic DNA triggers interferon α and β production through the RNA polymerase III transcription/RIG-I pathway leading to massive upregulation of APOBEC3A By catalyzing C→U editing in single stranded DNA fragments, the enzyme prevents them from re-annealing so attenuating the danger signal...

BACKGROUND: Although dietary flavonoid intake has been associated with less weight gain, there are limited data on its impact on fat mass, and to our knowledge, the contribution of genetic factors to this relation has not previously been assessed. OBJECTIVE: We examined the associations between flavonoid intakes and fat mass. DESIGN: In a study of 2734 healthy, female twins aged 18-83 y from the TwinsUK registry, intakes of total flavonoids and 7 subclasses (flavanones, anthocyanins, flavan-3-ols, flavonols, flavones, polymers, and proanthocyanidins) were calculated with the use of food-frequency questionnaires...

The increasing numbers of aging and chronically ill prisoners incarcerated in Western nations is well-documented, as is the growing need for prison-based palliative and end-of-life care. Less often discussed is specifically how end-of-life care can and should be provided, by whom, and with what resources. One strategy incorporates prisoner volunteers into end-of-life services within a peer-care program. This article reports on one such program based on focused ethnographic study including in-depth interviews with inmate hospice volunteers, nursing staff, and corrections officers working in the hospice program...

A current challenge in the treatment of peritoneal carcinomatosis is the inability to detect, visualize, and resect small or microscopic tumors of pancreatic, ovarian or mesothelial origin. In these diseases, the completeness of primary tumor resection is directly correlated with patient survival, and, hence, identifying small sub-mm tumors (i.e., disseminated disease) is critical. Thus, new imaging techniques and probes are needed to improve cytoreductive surgery and patient outcomes. Highly-fluorescent rhodamine-labeled expansile nanoparticles (HFR-eNPs) are described for use as a visual aid during cytoreductive surgery of pancreatic carcinomatosis...

BACKGROUND: Large quantities of blackberry seeds are produced as a pomace during the processing of juice and jam production - this by-product is a very interesting raw material both for oil manufacturing and as a source of bioactive compounds. In this work the composition, yield and antioxidant activity of three types of Rubus fructicosus pomace extracts isolated by liquid-extraction using solvents of different polarity, as well with supercritical CO2 fluid extraction have been compared...

BACKGROUND: There has been increasing interest in the use of selected non-Saccharomyces yeasts in co-culture with Saccharomyces cerevisiae. In this work, three non-Saccharomyces yeast strains (Metschnikowia viticola, Metschnikowia fructicola and Hanseniaspora uvarum) indigenously isolated in Denmark, were used in sequential fermentations with S. cerevisiae on three cool-climate grape cultivars Bolero, Rondo and Regent. During the fermentations, the yeast growth was determined as well as key oenological parameters, volatile compounds and sensory properties of finished rosé wines...

BACKGROUND: Increasingly, the experiences and perceptions of parents who decline vaccination are the subject of investigation. However, the experiences of clinicians who encounter these parents in the course of their work has received little academic attention to date. This study aimed to understand the challenges faced and strategies used when general practitioners and immunising nurses encounter parents who choose not to vaccinate their children. METHODS: Primary care providers were recruited from regions identified through the Australian Childhood Immunisation Register (ACIR) as having higher than national average rates of registered objection to childhood vaccination...

Anger in the context of psychosis has a significant impact on treatment outcomes and serious implications for risk management. Understanding mechanisms underlying anger will improve interventions and inform strategies for prevention. This study is the first to examine the relationships between anger and key theoretical drivers across different phases of the psychosis continuum. A battery including measures of theory of mind, attachment, hostile attribution bias, paranoia and anger was administered to 174 participants (14 ultra-high risk, 20 first-episode, 20 established psychosis, 120 non-clinical participants)...
