In 2012, the Washington raspberry (Rubus idaeus) industry received a special local needs (SLN) 24(c) label to apply Vydate L(®) (active ingredient oxamyl) to nonbearing raspberry for the management of Pratylenchus penetrans. This is a new use pattern of this nematicide for raspberry growers; therefore, research was conducted to identify the optimum spring application timing of oxamyl for the suppression of P. penetrans. Three on-farm trials in each of 2012 and 2013 were established in Washington in newly planted raspberry trials on a range of varieties...

In this manuscript, we have introduced a novel method to improve the catalytic activity of metal nanoparticles via optimizing the support structure. To this end, raspberry-like γ-Fe2O3/crackled nitrogen-doped carbon (CNC) capsules were prepared by a two-step method. Compared with traditional magnetic capsules, in γ-Fe2O3/CNC capsules, the γ-Fe2O3 nanoparticles were embedded in a CNC shell; therefore, they neither occupied the anchoring sites for metal nanoparticles nor came into contact with them, which was beneficial for increasing the metal nanoparticle loading...

We report a case of clear cell carcinoma (CCC) of the ovary with plasma cell-rich inflammatory stroma, a recently proposed subtype of CCC, and present the cytological findings. The patient was a 48-year-old woman, who was incidentally found to have a right ovarian tumor during the preoperative work-up for an early-stage adenocarcinoma of the uterine cervix. Cytological examination of an imprint smear of the ovarian tumor and peritoneal washing revealed solid cell clusters of irregular, often dendritic shapes, which were intermingled with many inflammatory cells...

Aberrant methylation of DNA is a common event in the development of cancers, including squamous cell carcinoma (SCC) of the human esophagus. In the present study, we determined: (a) whether aberrant DNA methylation also occurs in the development of N-nitrosomethylbenzylamine (NMBA)-induced tumorigenesis in the rat esophagus, a model of human esophageal SCC; and (b) if so, whether dietary black raspberries (BRBs) are capable of preventing this aberrant DNA methylation. A diet containing 5% BRBs inhibited the development of NMBA-induced tumors in the rat esophagus...

Drosophila suzukii Matsumura (Diptera: Drosophilidae) is an invasive pest in North America and Europe that attacks soft-skinned ripening fruit such as raspberries, blackberries, and blueberries. Little is known regarding the specific cues D. suzukii utilizes to locate and select host fruit, and inconsistencies in trap performance indicate the need for the development of improved monitoring and management techniques for this insect. Our studies focused on identifying attractive visual cues for adult D. suzukii and incorporating these cues into a potential attract-and-kill tactic for D...

Heterocoagulation of colloid particles with opposite surface charge has been used for the preparation of composite microspheres with specifically designed suprastructure, such as those with raspberry-like surface morphology and core-shell microspheres, which are difficult to achieve through other techniques. Here we report our investigation on the heterocoagulation of cationic polystyrene (PS) particles with anionic poly(methyl methacrylate) (PMMA) particles by a novel technique, i.e., by following online the evolution of the light transmittance in the process with practically no disturbance of the dispersion and no post-treatment for the samples...

Ellagic acid is a natural anti-oxidant phenol found in numerous fruits and vegetables, in particular pomegranate, persimmon, raspberry, black raspberry, strawberry, peach, plumes, nuts (walnuts, almonds), and wine. The anti-proliferative and anti-oxidant properties of ellagic acid have prompted research into its potential health benefits. The aim of this chapter will be to summarize potential benefits of ellagic acid supplementation in chronic diseases.

Ileostomy studies provide a unique insight into the digestion of foods, allowing identification of physiologically relevant dietary phytochemicals and their metabolites that are important to gut health. We previously reported an increase of components, including novel triterpenoids, in ileal fluids of 11 ileostomates following consumption of raspberries using nontargeted LC-MS(n) techniques in combination with data deconvolution software. The current study focused on components that consistently decreased postsupplementation...

SCOPE: Ileostomy studies provide a unique insight into digestion of food, allowing identification of physiologically relevant dietary phytochemicals and their metabolites important to gut health. We previously reported the consistent increase of components in ileal fluids of ileostomates after consumption of raspberries with use of non-targeted LC-MS(n) techniques and data deconvolution software highlighting two major unknown components (m/z 355 and 679). METHODS AND RESULTS: In-depth LC-MS(n) analyses suggested that the ileal m/z 355 components were p-coumaroyl glucarates...

Belowground tri-trophic study systems present a challenging environment in which to study plant-herbivore-natural enemy interactions. For this reason, belowground examples are rarely available for testing general ecological theories. To redress this imbalance, we present, for the first time, data on a belowground tri-trophic system to test the slow growth, high mortality hypothesis. We investigated whether the differing performance of entomopathogenic nematodes (EPNs) in controlling the common pest black vine weevil Otiorhynchus sulcatus could be linked to differently resistant cultivars of the red raspberry Rubus idaeus...

This paper presents a facile and flexible synthesis platform for various 3D porous gold-iron nanostructures based on selective laser heating of colloidal nanoparticles and selective acid treatment. The presented approach allows to create porous gold-based nanostructures with different morphologies. In addition, for the first time, our studies indicate that various nanoarchitectures (brain-like, flower-like, cage-like, or raspberry-like structures) can be obtained by varying the experimental conditions such as size of Au and Fe3O4 nanoparticles, solvent, laser fluence, and irradiation time...

Patterning of colloidal particles with chemically or topographically distinct surface domains (patches) has attracted intense research interest. Surface-patterned particles act as colloidal analogues of atoms and molecules, serve as model systems in studies of phase transitions in liquid systems, behave as 'colloidal surfactants' and function as templates for the synthesis of hybrid particles. The generation of micrometre- and submicrometre-sized patchy colloids is now efficient, but surface patterning of inorganic colloidal nanoparticles with dimensions of the order of tens of nanometres is uncommon...

Neuroinflammation is an integral part of the neurodegeneration process inherent to several aging dysfunctions. Within the central nervous system, microglia are the effective immune cells, responsible for neuroinflammatory responses. In this study, raspberries were subjected to in vitro digestion simulation to obtain the components that result from the gastrointestinal (GI) conditions, which would be bioaccessible and available for blood uptake. Both the original raspberry extract and the gastrointestinal bioaccessible (GIB) fraction protected neuronal and microglia cells against H2O2-induced oxidative stress and lipopolysaccharide (LPS)-induced inflammation, at low concentrations...

Genomic sequencing technology is moving rapidly from the research setting into clinical medicine but significant technological and interpretive challenges remain. Exome sequencing (ES) in its recent clinical application provides a genetic diagnosis in about 25 per cent of cases (Berg 2014). While this diagnostic yield is substantial, it also indicates that in a majority of cases, patients are receiving negative results (i.e. no explanatory genetic variant found) from this technology. There are a number of uncertainties regarding the meaning of a negative result in the current context of ES...
