Microbial Safety of Dairy Manure Fertilizer Application in Raspberry Production
Dairy manure, a by-product in the dairy industry, is also a potential source of nutrients for crops. However, improper application of biological soil amendments of animal origin can be a source of contamination with enteric foodborne pathogens. A 2-year field study was conducted to evaluate impacts of dairy manure fertilizer application on the microbial safety of red raspberry (Rubus idaeus L) production. Fertilizers, including a standard synthetic fertilizer (CON), straight lagoon raw manure (SL), anaerobically digested liquid effluent (DLE), compost (COM) and dairy manure-derived refined fertilizers including ammonium su...

Raspberry (Rubus idaeus L.) fruit extract decreases oxidation markers, improves lipid metabolism and reduces adipose tissue inflammation in hypertrophied 3T3-L1 adipocytes
In this study, we investigated the ability of raspberry fruit extract (RBE) to mitigate adipose tissue dysfunction using hypertrophied 3T3-L1 adipocytes. The obtained results showed that RBE decreased intracellular ROS generation in hypertrophied adipocytes by enhancing expression of antioxidant defense enzymes SOD, catalase, and GPx, and inhibiting an oxidant enzyme NADPH oxidase 4. Moreover, RBE reduced lipid accumulation accompanied by increased lipid mobilization. RBE significantly inhibited LPL, aP2, FAS and PLIN mRNA expression, and enhanced the expression of HSL. Furthermore, RBE exhibited a high anti-inflammatory p...

What do we know about raspberry leaf?
Background: Midwives and women have been using raspberry leaf (Rubus idaeus) to help birth since at least the 6th Century. Recent surveys tell us that raspberry leaf use is still prevalent all over the world. Research from Melbourne identified that over a third of Australian women are taking herbal supplements to help their birth, with the most common being Raspberry Leaf. While there is a long history of anecdotal use, women are taking Raspberry Leaf in their pregnancy without any clinical evidence for efficacy or safety. (Source: Women and Birth)

A New Protocol for Molecular Detection of Cyclospora cayetanensis as Contaminants of Berry Fruits
Cyclospora cayetanensis is a coccidian parasite that has been associated with foodborne outbreaks of gastrointestinal illnesses. Raspberries have been implicated as vehicle of infection in some of these outbreaks. Most of the molecular techniques used for the detection of parasites commonly use the 18s rRNA as a target gene, which is highly conserved. The conserved nature of 18s rRNA gene among coccidia means that there is potential for cross-reactivity from primers intended to target this gene in C. cayetanensis with the same gene in related coccidia. This provides an additional challenge in developing a specific detectio...

Effects of Black Raspberries and Their Constituents on Rat Prostate Carcinogenesis and Human Prostate Cancer Cell Growth In Vitro.
Abstract Prostate cancer patients often use dietary supplements, such as black raspberries, which are a rich source of compounds with antioxidant and anticancer activity, particularly on gastrointestinal cancers. Feeding black raspberries inhibited mammary cancer induction in rats and growth of cancer cells in nude mice, indicating systemic bioavailability of bioactive compounds. We tested whether feeding black raspberries and its constituents would inhibit prostate cancer development. However, we did not find preventive effects in two rat prostate carcinogenesis models, even though the berry anthocyanin metabolit...

The effect of potato protein (PP) (as a foaming agent), maltodextrin (MD) (as a foam stabilizer), and microwave power on the product characteristics was investigated. The puree contained 18%–20% higher content of anthocyanins and ascorbic acid than unprocessed raspberries. The retention of ascorbic acid and anthocyanins increased with increasing concentrations of MD and PP. Both drying methods resulted in 66%–81% retention of ascorbic acid and 53%–84% retention of to...

Dietary administration of black raspberries modulates arsenic biotransformation and reduces urinary 8-oxo-2'-deoxyguanosine in mice.
Abstract Arsenic in drinking water is a worldwide public health problem due to its pathogenic induction of oxidative stress in various organ systems. Phytochemicals present in polyphenolic-rich fruits such as black raspberries (BRBs) have diverse health benefits, including antioxidation and modulation of enzymes in xenobiotic metabolism. We used a mouse model combined with a standardized BRB-rich diet to investigate the impact of BRB consumption on arsenic biotransformation. We observed a significant reduction of urinary 8-oxo-2'-deoxyguanosine (8-oxodG) together with elevated levels of methylation and urinary exc...

Abstract Consumption of certain berries appears to slow postprandial glucose absorption, attributable to polyphenols, which may benefit exercise and cognition, reduce appetite and/or oxidative stress. This randomised, crossover, placebo-controlled study determined whether polyphenol-rich fruits added to carbohydrate-based foods produce a dose-dependent moderation of postprandial glycaemic, glucoregulatory hormone, appetite and ex vivo oxidative stress responses. Twenty participants (eighteen males/two females; 24 (sd 5) years; BMI: 27 (sd 3) kg/m2) consumed one of five cereal bars (approximately 88 % carbohydrate)...

Thorny problem
Publication date: 7 July 2018Source: New Scientist, Volume 239, Issue 3185Author(s): I am puzzled by brambles, raspberries and blackberries. They have sweet, juicy fruit, presumably so they will be eaten by animals who will spread their seeds. But they also have prickles. What's the good of that? (Source: New Scientist)

Rubus idaeus L. (red raspberry) blocks UVB-induced MMP production and promotes type I procollagen synthesis via inhibition of MAPK/AP-1, NF-κβ and stimulation of TGF-β/Smad, Nrf2 in normal human dermal fibroblasts
In this study, we demonstrated that RI could reverse this damage via increasing procollagen synthesis and blocking MMPs, inflammatory factors expression. The studies of molecular mechanism indicated RI could inhibit MMPs expression via inactivating MAPK/AP-1, NF-κβ pathway and accelerate type I procollagen synthesis through activating the TGF-β/Smad pathway. Furthermore, RI reduced UVB-enhanced ROS via promoting Nrf2 nuclear location and enhancing the expression of cytoprotective antioxidants.
