In vitro propagation, also known as micropropagation, has become the most widely employed method for blackberry propagation, as it overcomes the limitations of the traditional asexual propagation methods (mainly layering and cutting). In this context, synthetic seed technology represents a strategy to enhance the productivity of in vitro propagation and facilitates the exchange of plant materials between laboratories, contributing to germplasm conservation. This study aimed to identify the most suitable vegetative propagule for the encapsulation of blackberry...

BACKGROUND AND AIMS: The softening of ripening fruit involves partial depolymerisation of cell-wall pectin by three types of reaction: enzymic hydrolysis, enzymic elimination (lyase-catalysed) and non-enzymic oxidative scission. Two known lyase activities are pectate lyase and rhamnogalacturonan lyase (RGL), potentially causing mid-chain cleavage of homogalacturonan and rhamnogalacturonan-I (RG-I) domains of pectin respectively. However, the important biological question of whether RGL exhibits action in vivo had not been tested...

BACKGROUND: Aboriginal and Torres Strait Islander people are ageing with high rates of comorbidity, yet little is known about suboptimal prescribing in this population. AIM: The prevalence of potentially suboptimal prescribing and associated risk factors were investigated among older patients attending primary care through Aboriginal Community Controlled Health Services (ACCHSs). METHODS: Medical records of 420 systematically selected patients aged ≥50 years attending urban, rural and remote health services were audited...

Blackberry crude polysaccharides (BCP) was added to chicken breast to inspect the intermolecular interaction with myofibrillar protein (MP). The influence of BCP on the thermal transformation behavior and protein micro-structure during temperature rise period was studied. The results showed that the interaction between BCP and MP was mainly affected by the concentration of BCP and heating temperature. The results of infrared spectrophotometer and nano-particle/zeta potentiometer showed that a BCP-MP complex was generated through hydrogen bond and electrostatic interaction, which could promote the transformation of MP from β-folding to β-Angle transformation...

INTRODUCTION: Poor sleep is associated with numerous adverse health outcomes. Berries are rich in micronutrients and antioxidants that may improve sleep quality and duration. We determined the association of berry consumption and sleep duration and sleep difficulty among adult participants in NHANES. METHODS: We analyzed the diet of US adults aged ≥ 20 y using two non-consecutive 24 h recalls from the National Health and Nutrition Examination Survey 2005 to 2018 ( N = 29,217)...

The goal of this research was nutritional evaluation through the phytochemical analysis of blackberry and raspberry leaves, the screening of their biological activity (antioxidant capacity and inhibition of lipid peroxidation), and the investigation of the effect of in vitro gastrointestinal digestion (GID) of blackberry and raspberry leaves on the bioaccessibility of polyphenol subclasses. The concentrations of the analyzed liposoluble antioxidants were higher ( p < 0.05) in blackberry leaves compared to raspberry leaves, while a significant ( p < 0...

Metabolic syndrome (MetS) is a complex disease that includes metabolic and physiological alterations in various organs such as the heart, pancreas, liver, and brain. Reports indicate that blackberry consumption, such as maqui berry, has a beneficial effect on chronic diseases such as cardiovascular disease, obesity, and diabetes. In the present study, in vivo and in silico studies have been performed to evaluate the molecular mechanisms implied to improve the metabolic parameters of MetS. Fourteen-day administration of maqui berry reduces weight gain, blood fasting glucose, total blood cholesterol, triacylglycerides, insulin resistance, and blood pressure impairment in the diet-induced MetS model in male and female rats...

OBJECTIVE: In Australia, breast screening is offered free every two years to women aged 50-74 years. Women aged ≥75 are eligible to receive a free mammogram but do not receive an invitation. This study aimed to explore the motivations and behaviours of women living in Australia aged ≥75 years regarding ongoing breast cancer screening given the public health guidance. METHODS: Sixty women aged ≥75 were recruited from metropolitan, regional, and rural areas across Australia to participate in a descriptive qualitative study...

To investigate the protective effect of blackberry anthocyanins (BA), tea polyphenols (TP), and their binary mixture on the oxidative stability of edible oils during storage, BA, TP, and their binary mixture were added to lard and olive oil. The changes in peroxide value (PV), thiobarbituric acid reactive substances (TBARS), acid value (AV), and scavenging capacity of DPPH and ABTS•+ of oil samples were evaluated during accelerated storage. BA were found to have a remarkable capability to enhance antioxidant properties, delay lipid oxidation, and inhibit the deterioration both of lard and olive oil at high-temperature processes...

BACKGROUND: Across the care economy there are major shortages in the health and care workforce, as well as high rates of attrition and ill-defined career pathways. The aim of this study was to evaluate current evidence regarding methods to improve care worker recruitment, retention, safety, and education, for the professional care workforce. METHODS: A rapid review of comparative interventions designed to recruit, retain, educate and care for the professional workforce in the following sectors: disability, aged care, health, mental health, family and youth services, and early childhood education and care was conducted...

Several viruses are transmitted by eriophyid mites (Acariformes: Eriophyoidea) including blackberry leaf mottle-associated emaravirus (BLMaV) (Emaravirus rubi). BLMaV is transmitted by an unidentified eriophyid species and is involved in blackberry yellow vein, a devastating disease in the southeastern United States. In this study, we assessed the eriophyid mite Phylocoptes parviflori as a vector of BLMaV and clarified its taxonomic status as it was previously synonymized with Phyllocoptes gracilis. P. parviflori can efficiently transmit BLMaV...

Berry production is increasing worldwide each year; however, high production leads to labor shortages and an increase in wasted fruit during harvest seasons. This problem opened new research opportunities in computer vision as one main challenge to address is the uncontrolled light conditions in greenhouses and open fields. The high light variations between zones can lead to underexposure of the regions of interest, making it difficult to classify between vegetation, ripe, and unripe blackberries due to their black color...

Anti-oxidant, -inflammatory, and -carcinogenic activities of bioactive plant constituents, such as anthocyanins, have been widely discussed in literature. However, the potential interaction of anthocyanin-rich extracts with routinely used chemotherapeutics is still not fully elucidated. In the present study, anthocyanin-rich polyphenol extracts of blackberry (BB), bilberry (Bil), black currant (BC), elderberry (EB), and their respective main anthocyanins (cyanidin-3- O -glucoside, delphinidin-3- O -glucoside, cyanidin-3- O -rutinoside, and cyanidin-3- O -sambubioside) were investigated concerning their cytotoxic and DNA-damaging properties in murine CT26 cells either alone or in combination with the chemotherapeutic agent SN-38...

Retention of care support workers in residential aged care facilities and home-based, domiciliary aged care is a global challenge, with rapid turnover, low job satisfaction, and poorly defined career pathways. A mixed-methods systematic review of the workforce literature was conducted to understand the factors that attract and retain care staff across the aged care workforce. The search yielded 49 studies. Three studies tested education and training interventions with the aim of boosting workforce retention and the remaining 46 studies explored opinions and experiences of care workers in 20 quantitative, four mixed-methods and 22 qualitative studies...

Kefir is a fermented dairy product claimed to confer many health-promoting effects, but its acidic taste is not appealing to some consumers. Therefore, the aim of this study was to enhance the functional and sensorial quality attributes of kefir through fortification with encapsulated blackberry juice (EBJ). The blackberry juice was successfully encapsulated via freeze-drying using lentil protein isolate (LPI) as the carrier. The encapsulated blackberry juice showed good physicochemical, functional, and morphological properties, as well as microbiological safety for use as a food additive...

Blackberries are abundant in substances that have antioxidative and other effects, and technologies for enhancing the effectiveness of their incorporation into the body are being developed. The effectiveness of such substances has been investigated in various models, including rodent ischemia models. While a test substance can be administered either before or after an event, healthy foods are generally pre-administered prophylactically in experiments. Pre-administration may have the potential to elevate the blood concentration of the active substance sufficiently prior to the event and/or induce adaptive changes in the ischemic tolerance of the recipient through long-term pre-administration...

Bacillus cereus is estimated to be responsible for 1.4-12% of all food poisoning outbreaks worldwide. The objective of this study was to investigate the toxigenic potential of 181 isolates of B. cereus previously recovered from different types of berries and berry products (strawberries, raspberries, blackberries, and blueberries) by assessing the presence of enterotoxin genes ( hblA , hblC , hblD , nheA , nheB , nheC , and cytK ) and an emetic toxin cereulide synthetase gene ( ces ). The cytotoxic activity on Caco-2 cells was also evaluated for the two isolates containing the gene cytK ...

Electronic cigarettes (e-cigarettes) have gained popularity; however, evidence for their safety with chronic use is lacking. Acute e-cigarette exposure induces systemic oxidative stress in users and contributes to vascular endothelial dysfunction through reduction in nitric oxide (NO). Polyphenols, abundant in blackberries (BL), mitigate cardiovascular damage. We aimed to determine whether BL was protective against e-cigarette-induced cardiopulmonary detriments. Mice were fed a diet supplemented with or without 5% freeze-dried BL (w/w) for 16 weeks...

We propose a modification of terbium-sensitized luminescence (TSL) by means of the introduction of nanoparticles to improve the sensitivity and selectivity of the analytical methods. TSL detection is usually based on the complexation between fluorescent organic compounds (the analytes) and terbium. The organic compound is then excited, and, after an energy transfer towards terbium, the latter emits the luminescence signal. Here, the modification consists of the introduction of nanoparticles (carbon quantum dots, CQDs) into the system...

Blackberry fruit contains high levels of nutrients and phenolic compounds. Blackberry pomace accounts for 20~30% of its whole fruit during processing and is generally treated as fertilizer. Blackberry pomace has many seeds that contain carbohydrates, polyphenols, flavonoids, pectin, protein, and other bioactive nutrients. However, its functional properties and seed protein compositions have not been reported. We used a single-factor experiment, response surface, and Osborne isolate method to extract protein isolate, albumin, globulin, glutelin, and prolamin from blackberry seeds for the first time and evaluated their characteristics and functional properties...
