This study investigated the effects of color shade and curing time on the degree of conversion (DC) and microhardness of colored compomers. A total of 162 samples (81 for DC, 81 for microhardness) were prepared, with nine samples per color group (gold, blackberry, green, pink, orange, lemon, blue, silver) and for the control. Samples were subdivided into three polymerization subgroups (3 s/3200 mW/cm2, 10 s/1000 mW/cm2, 20 s/1000 mW/cm2). The DC was analyzed via fourier transform infrared spectroscopy (FTIR) and microhardness was measured using Vickers testing. Statistical analysis included two-way ANOVA and Spearman correlation (α = 0.05). The colored compomers demonstrated a significantly lower DC compared to the control group (p ≤ 0.001). Among the tested colors, green exhibited the lowest DC (33.3%), while orange showed the highest (51.0%). A significant difference in DC was observed across curing times (p = 0.005), with the 3 s and 20 s groups exhibiting significantly higher conversion rates than the 10 s group. Microhardness values exhibited significant variation depending on the color (p < 0.001). Gold compomers demonstrated the lowest microhardness, whereas silver compomers showed comparable performance with the control group (p = 0.154). A moderate correlation between DC and microhardness was observed overall (ρ = 0.42, p = 0.003). However, the observed relationships were color-dependent: orange displayed a strong positive correlation (ρ = 0.78), whereas pink revealed no meaningful association (ρ = −0.15). Color and curing time critically influence compomer performance. High-intensity short curing is viable for lighter colors, while darker colors require extended curing. Customized protocols are essential to optimize clinical outcomes in pediatric dentistry. Full article

Background: Blackberry seed oil (BSO), obtained from Rubus spp. Xavante cultivar via supercritical CO2 extraction, contains bioactive lipids and antioxidants, but its cosmetic application is limited by poor solubility and stability. Nanoencapsulation with poly(ε-caprolactone) (PCL) can overcome these limitations. Methods: BSO was characterized by Ultra-High-Performance Liquid Chromatography coupled with electrospray ionization quadrupole time-of-flight mass spectrometry and incorporated into PCL nanocapsules (NCBSO) using the preformed polymer deposition method. Physicochemical properties, stability (at 4 °C, room temperature, and 37 °C for 90 days), cytotoxicity, and collagen production were assessed in human fibroblasts. Additionally, a predictive in silico analysis using PASS Online, Molinspiration, and SEA platforms was performed to identify the bioactivities of major BSO compounds related to collagen synthesis, antioxidant potential, and anti-aging effects. Results: NCBSO showed a nanometric size of ~267 nm, low polydispersity (PDI < 0.2), negative zeta potential (−28 mV), and spherical morphology confirmed by FE-SEM. The dispersion remained stable across all tested temperatures, preserving pH and colloidal properties. In particular, BSO and NCBSO at 100 µg.mL−1 significantly enhanced in vitro collagen production by 170% and 200%, respectively, compared to untreated cells (p < 0.01). Superior bioactivity was observed for NCBSO. The in silico results support the role of key compounds in promoting collagen biosynthesis and protecting skin structure. No cytotoxic effects were achieved. Conclusions: The nanoencapsulation of BSO into PCL nanocapsules ensured formulation stability and potentiated collagen production. These findings support the potential of NCBSO as a promising candidate for future development as a collagen-boosting cosmeceutical. Full article

Optimized in vitro cultivation offers a sustainable solution to enhance blackberry (Rubus spp.) production while reducing pathogen contamination during propagation. This study developed and validated protocols for in vitro cultivation and ex vitro acclimatization of the Tupy, Brazos, and Kiowa cultivars at the Instituto Tecnológico Superior de Los Reyes, Michoacán. A 20 min treatment with 2% sodium hypochlorite (NaOCl) reduced contamination by below 10% and achieved explant survival rates exceeding 95%. Temporary Immersion Systems (TIS) with four to six immersion cycles of 5 min each maximized survival (above 95%) while minimizing necrosis and hyperhydricity and increasing fresh mass. Shoot development was significantly enhanced with 2 mg L−1 6-benzylaminopurine, and 1 mg L−1 indole-3-butyric acid promoted optimal root formation. Acclimatization success rates exceeded 90% in covered trays compared to significant losses in uncovered trays during early stages. These protocols enabled robust plant development and yields exceeding 10 t ha −1 during vegetative and reproductive stages, providing a scalable framework for sustainable blackberry production and broader applications in crop propagation.

Dietary polyphenols’ role in early life is not clear. While accumulating studies show both beneficial and deleterious effects of maternal consumption of these bioactive compounds on offspring’s adult health, very few studies have focused on the impact of paternal consumption. In addition, the potential interaction of combined parental polyphenol consumption is still not known. Thus, the aim of the present study was to investigate the effects of maternal (gestation/lactation) and/or paternal (preconception) blackberry polyphenol (anthocyanins, ellagitannins, and quercetin) methanolic extract consumption on C57BL/6 female mice offspring. Blackberry polyphenol consumption by fathers improved their sperm production and increased fertility. Blackberry polyphenol consumption by fathers, but not mothers, increased their plasma antioxidant capacity. All parental interventions decreased offspring perinatal mortality, with combined fathers’ and mothers’ polyphenol consumption exerting the most pronounced effects. Paternal or maternal polyphenol consumption decreased plasma total antioxidant capacity in the female offspring. On the other hand, combined parental consumption had opposing effects on the offspring. Only maternal polyphenol interventions increased glucose tolerance in the female offspring. These data only partially confirm our hypothesis that combined paternal and maternal polyphenol intervention would lead to better outcomes in the offspring. These results further show that blackberry polyphenols’ effects on offspring health depend on whether their consumption occurred through the father, mother, or both. This suggests that in order to promote long-term health in descendants, nutritional interventions, including those with polyphenols, should target not only the mother but also the future father.

Silver nanoparticles, with various uses in pharmacy, cosmetics, sanitation, textiles, optoelectronics, photovoltaics, etc., that are provided by worldwide industrial production, estimated to hundreds of tons annually, are finally released in the environment impacting randomly the biosphere. An alternative synthesis approach could be implemented by replacing chemical reductants of silver with natural antioxidants ensuring production and utilization sustainability with focus on environmental pollution diminishing. We synthesized silver nanoparticles by using plant extracts, aiming to offer antimicrobial products with reduced impact on the environment through sustainable green-chemistry. Fresh extracts of lemon pulp, blueberry and blackberry fruits as well as of green tea dry leaves were the sources of the natural antioxidants able to ensure ionic silver reduction and silver nanoparticle formation in the form of colloidal suspensions. The four samples were characterized by UV–Vis spectrophotometry, scanning electron microscopy, dark field optical microscopy, X-ray diffractometry, dynamic light scattering, which evidenced specific fine granularity, plasmonic features, standard crystallinity, and good stability in water suspension. Antimicrobial activity was assayed using the agar diffusion method and the bacteria kill-time technique against Staphylococcus aureus and Escherichia coli. In both cases, all silver nanoparticles revealed their adequacy for the aimed purposes, the sample synthesized with green tea showing the best efficiency, which is in concordance with its highest contents of polyphenols, flavones and best total antioxidant activity. Various applications could be safely designed based on such silver nanoparticles for sustainable chemistry development. Full article

Ecological determinants of avian population dynamics are essential for effective wildlife management and conservation. Black and grey francolins are classified as being of least concern by the IUCN and are an ecologically significant bird in the northern regions of Pakistan. Although habitat degradation and overhunting have adversely affected their populations, research on the population structure and habitat preferences of the Totali Game Reserve, Buner District, Pakistan, remains limited. The present study applied distance sampling via the line transect method to estimate population densities and the quadrat method to assess vegetation characteristics across three distinct habitats. A statistical analysis revealed significant variations in densities across the three habitat types—agricultural lands, agroforests, and pasturelands—with both species exhibiting distinct preferences for pastureland ecosystems. Seasonal trends indicated that autumn represented the peak period for the population, driven by post-breeding surges and optimal habitat conditions. Moreover, both species demonstrated a strong affinity for habitats dominated by specific plant species, including hopbush, raspberry, barberry, and blackberry, which provide a critical resource for food, foraging, nesting, and shelter. These findings highlight the ecological importance of pasturelands and specific vegetation types for supporting the survival of these species. Furthermore, conservation efforts should prioritize the preservation and restoration of pastureland ecosystems and incorporate rigorous monitoring programs to guide adaptive management strategies aimed at mitigating population declines.

Micropropagation of blackberry (Rubus spp.) has emerged as a key technique for large-scale production of genetically uniform, disease-free plants. This review summarizes more than half a century of in vitro blackberry culture research, covering fundamental aspects such as establishment, proliferation, rooting, acclimation, genetic stability and conservation. Optimization of culture media, plant growth regulators and environmental conditions has significantly improved the efficiency of micropropagation. Recent advances, including bioreactors, cryopreservation and biostimulants, have further improved plant growth and stress tolerance. In addition, studies on bioactive compounds in micropropagated blackberries highlight their potential nutritional and pharmaceutical applications. Despite progress, challenges such as microbial contamination, somaclonal variation, and response variability among cultivars remain critical areas for future research. The integration of nanotechnology, alternative culture systems (i.e., bioreactors), synthetic seed technology should represent the future research trend of blackberry micropropagation, ensuring sustainable production and conservation of genetic resources.

The objective of the present study was to determine the effect of mixed plant extracts on chemical (pH, total volatile base nitrogen (TVB-N), trimethylamine nitrogen (TMA), thiobarbituric acid reactive substances (TBARS), biogenic amines, relative fatty acid composition) and microbiological quality indicators of vacuum-packed fish burgers stored at 0 ± 2 °C over 13 days. Three mixtures of common juniper by-product and blackberry leaves extracts (JB), Padina pavonica and prickly juniper needles extracts (PCJ), and blackberry leaves extract with catechin and vanillic (BCV) were tested. At the end of storage, TVB-N (15.38–20.03 mg/100 g) and TMA (10.64–15.63 mg/100 g) of burgers with extracts were significantly lower than those of the control group (22.77 mg TVB-N/100 g, 18.37 mg TMA/100 g). The TBARS values in the control burger reached 2.62 ± 0.02 µmol malondialdehyde (MDA)/100 g, while in burgers with extracts, final values were in the range of 0.62 ± 0.01 to 0.80 ± 0.02 µmol MDA/100 g. The extracts showed no effect on biogenic amine formation (tryptamine, putrescine, and cadaverine levels increased during the storage, being the lowest in BCV) or microbial counts, with the exception of the Pseudomonas sp. counts that were significantly lower in JB and PCJ in comparison to the control, reaching 4.1, 4.1, and 5.0 log CFU/g in JB, PCJ, and control, respectively.

Fiber is one of the most important ingredients of fruit that has an influence on the gastrointestinal tract and biochemical parameters of blood. Fiber has texturizing functions in food processing. The fiber’s properties (water-binding capacity, swelling, and oil-holding capacity) and polysaccharide composition obtained from raspberry and blackberry fruit, juice, and pomace, divided into seed and seedless fractions, were determined. The seedless fraction contains more hemicelluloses and homogalacturonan with higher water-binding capacities, swelling, and oil-holding capacities, and the seeds contain more cellulose, and their physical abilities are much lower. Water-binding capacities were from 2.7 to 14.9 g/g, swelling from 3.3 to 11.1 mL/g, and oil-holding capacities from 8.0 to 16.5 g/g. The sequential extraction of fruit fiber showed that the main fraction was the Residue, followed by the weak alkali extractable pectin (DASP) and the hemicellulose (CASP). Water-extractable pectin (WSP) and chelating-agent extractable pectin (ChSP) both constituted 8–9% of AIS each. In the pomace, the main fraction was the Residue (40% AIS), followed by CASP (16% AIS), DASP and ChSP (6–7% AIS), and WSP and WR (3% AIS). While seeds are composed mostly of Residue (52–57% AIS vs. 24–36% AIS in seedless), the seedless part shares of CASP hemicelluloses were higher (24–28% AIS vs. 12–15% in seeds). In the seedless part, there was also more water-soluble pectin (WSP) (4–5% vs. 2–3% in seeds). Seedless fraction is rich in hemicellulose and has higher water-binding properties and oil-holding capacities compared to seeds, and that is why it could be a source of functional berry polysaccharides.

This study investigates the potential of blackberry juice fortified with whey as a carrier for transporting and protecting lactic acid bacteria (LAB). The interactions between whey proteins and the juice were examined to assess their impact on probiotic stability and protection during storage and passage through the gastrointestinal tract. Additionally, the study explored how this combination influences the antioxidant properties of the product. The results indicated that the blackberry juice and whey protein mixture provided moderate protection to Lacticaseibacillus rhamnosus GG compared to the positive control (inulin), suggesting that whey proteins may enhance probiotic viability. Proteolytic analysis revealed progressive protein hydrolysis during fermentation, leading to the release of bioactive peptides, indicating the formation of compounds with potential functional benefits. Moreover, samples inoculated with LAB exhibited higher antioxidant activity than those without inoculum. This research demonstrates the promise of fermented blackberry juice fortified with whey proteins as an effective probiotic delivery system. It opens new possibilities for developing functional foods to promote intestinal health and overall well-being. Full article

The Australian Royal Commission into Aged Care Quality and Safety has highlighted the chronic shortages of labour to provide care for those aged 65 and over in rural and remote areas of Australia. This descriptive cross-sectional study compares the availability of care provision in metropolitan regions with that in rural and remote regions. We analysed the 2021 Australian Census, grouped according to Aged-Care-Planning Region (ACPR), and investigated the numbers of people aged 65 years and over with different levels of care need, both in residential care and in-home. The available workforce in each ACPR was also examined in detail, using occupational classifications reported in the Census, and shortages of doctors, nurses, allied health and other care workers were identified. Overall, an additional 492,416 care hours were needed per week (or 12,958 full-time equivalent (FTE) care workers) in order to bring remote community ACPRs to parity with provision in metropolitan ACPRs. A further 95,342 FTE workers were needed in rural ACPRs to bring these areas to parity with metropolitan ACPRs. Our findings underscore the ongoing disparities in aged care workforce availability between metropolitan, rural, and remote regions of Australia. Addressing these workforce shortages is crucial to ensuring equitable access to care for older Australians, regardless of their geographical location. The implementation of targeted strategies to enhance workforce recruitment, retention, and training in these underserved areas is essential to bridge the gap and improve the quality of care provided to older adults in rural and remote communities. Such strategies could include targeted recruitment campaigns and incentives for professionals to relocate; further capacity for clinical placements and supervision in rural areas; tailoring funding and employment models for rural needs; and strengthening vocational education in regional areas.

Significant advances in winemaking equipment and processes, as well as a deeper understanding of the role of yeast, have significantly improved wine quality throughout history. This paper examines critical aspects related to the use of commercial wine yeast starter cultures in the fermentation of grape and fruit wines, with a focus on berry wines and blackberry wine, which is the most predominant berry wine in Croatia. While the production of grape wines remains the most significant, fruit wines are gaining importance due to their composition, which contains a variety of bioactive compounds. Although spontaneous fermentation is still preferred by some winemakers, controlled or inoculated fermentation, based on the use of wine yeast starter cultures, is predominantly employed in modern winemaking. The selection of suitable yeast strains for grape wines is easier than for fruit wines, as the broader availability of commercial yeasts for grape wines contrasts with the limited selection offered for fruit wine production due to the smaller fruit wine market. The selection of Saccharomyces and, more recently, non-Saccharomyces yeast strains with desirable characteristics are crucial for the production of high-quality wines. Selection criteria for wine yeasts have evolved to meet modern consumer preferences and focus on technological properties, secondary flavor development and health effects. Full article

This study aims to develop and evaluate pH-sensitive food packaging films, based on starch and enriched with aqueous wild blackberry extract (Rubus sp.). The extract was selected for its high anthocyanin content due to color changes in different pH environments. Extract analysis revealed a dry matter content of 23 mg/mL and a polyphenol concentration of 21.10 mg GAE/g (dry extract), with high antioxidant activity, measured to be an 86.57% DPPH radical neutralizer. Films were produced with wild blackberry extract at concentrations of 0%, 5%, 10%, and 15%. The analyses determined the barrier, mechanical, physical, and intelligent properties of biodegradable films. The introduction of the extract resulted in a substantial rise in water content (9.6–21.36%), swelling capacity (35.27–43.06%), dissolution rate in water (288.05–459.89%), and permeability to water vapor (1.99–3.69 × 10−10 g/(Pa × m × s)). The bioactive compounds in the extract enhanced the films’ antimicrobial and antioxidant properties, with the highest effectiveness observed in the film containing 15% extract. These starch-based films, enriched with aqueous wild blackberry extract, demonstrated strong potential for packaging foods prone to pH changes during fermentation, such as fruits, dairy products, meat, and fish.

The blackberry (Rubus fruticosus) is a red fruit with great potential as a functional food thanks to its composition, which is rich in antioxidants. This work focused on the study of two byproducts of blackberry (skins and seeds) after juice production, with the aim of characterizing them and studying their bioactivity. The phenolic composition and antioxidant capacity of the products, determined by ABTS, as well as their colonic fermentation fractions, were analyzed. In addition, their genotoxicity and effect on the intestinal microbiota were evaluated after in vitro gastrointestinal digestion and fermentation. Blackberry byproducts, namely skin and seeds, are rich in phenolic compounds, especially the skin, which is rich in anthocyanins and presents an antioxidant capacity that makes it potentially usable as a functional ingredient. All the fermented samples present in vitro genoprotective activity and a modulation effect on the intestinal microbiota, promoting the growth of Bifidobacterium and Lactobacillus and reducing the abundance of the Clostridia XIVa cluster and Faecalibacterium prausnitzii. A similar effect was observed for the skin and seeds. The results provide insights into the digestive properties and health benefits of blackberry byproducts after consumption. Full article

There are a multitude of raspberry and blackberry varieties, and each of them develops differently depending on environmental factors and cultivation technology, so much research is needed to see which variety has the best yield in a desired area. This paper studied the growth under natural soil and specific climate conditions in the Bucharest–Ilfov region of Romania of a raspberry plantation and a blackberry plantation, both in their first year of vegetation. The studied interval, the period of June to October 2024, was established from the beginning of the ripening of the first fruits to the late ripening of the fruits. The study analyzed the correlations between the vegetative and productive parameters of the raspberry variety “Delniwa” and the blackberry variety “Thornfree” on productivity per plant. During the study period, good shoot formation was observed, with an average height of 1400 mm for raspberries and 3474 mm for blackberries (r = 0.99 to raspberries and r = 0.98 to blackberries); a good development of the average stem diameter of 8.54 mm for raspberries and 12.78 mm for blackberries (r = 0.96 la zmeur si r = 0.89 la mur), of the number of ripe fruits harvested (r = 0.68 to raspberries and r = 0.58 to blackberries), all of which are correlated with increased productivity of 820 g/plant for raspberries and 2050 g/plant for blackberries. The experimental data were statistically analyzed using linearized, polynomial and hyperbolic models to identify the relationships between the studied variables and to highlight growth variations and fruit production in raspberries and blackberries throughout the season. In the first year of vegetation, both crops recorded constant growth but with different rhythms: raspberries showed constant fruit production, with a peak in June–July and a slight resumption in September, while blackberries had high production at the beginning of summer, followed by a significant decrease in August. The results obtained support farmers who grow raspberries and blackberries under similar natural pedo-climatic conditions, contributing to crop planning and production optimization. Full article
