Dinoflagellates play a key ecological role in marine environments, contributing significantly to primary production and, in some cases, causing harmful algal blooms (HABs). They exhibit diverse morphologies and ecological strategies to colonize a wide range of habitats. Research has predominantly focused on HAB-forming species due to their associated health risks, potentially underrepresenting benthic diversity. In this study, we bring the first report of the unarmored benthic dinoflagellate Bispinodinium angelaceum from a sandy-bottom tide pool in Tenerife, Canary Islands. Morphological identification was based on the observation of live cells using light microscopy (LM) to identify diagnostic features such as dorsoventral cell flattening, a centrally located epicone with a circular apical groove, symmetrical cingulum, brownish-yellow lobular chloroplasts, and a U-shaped spinoid apparatus connecting two lateral pyrenoids. B. angelaceum specimens from Tenerife were slightly larger when compared to previous descriptions but exhibited consistent proportions and structural organization which likely reflected methodological rather than taxonomical differences. This new record extends the known geographic range of the species and provides valuable baseline data for future ecological and taxonomic studies of benthic dinoflagellates, emphasizing the need to better explore and document the hidden diversity of non-HAB taxa.
Typically feminine morphological traits in women include a neotenous facial structure with large eyes, full lips, and an oval face shape, and a curvaceous body with large breasts, a narrow waist, and full hips and buttocks. Compared to men, women also show higher second-to-fourth finger (2D:4D) ratios as well as less muscle mass, lower physical strength, and a higher voice pitch. Due to a putative association with oestrogen levels, feminine traits are often claimed to cue women’s reproductive potential. However, the evidence for this is scarce and inconsistent, typically measuring proxies rather than actual fertility outcomes. Here, we report a systematic review of direct fertility measures as a function of morphological traits in women, including breast size, waist-to-hip ratio (WHR), voice pitch, strength, and 2D:4D; no articles were found measuring facial femininity. The review included 19 articles comprising 68 effect sizes (31 samples from 16 countries; total N = 125,062). Our review showed that a less feminine WHR may cue past fertility, and a more feminine 2D:4D may be, at best, weakly associated with fertility. Overall, we conclude that the current evidence base is too weak to support the claim that women’s feminine morphological traits are associated with reproductive potential.
The multilevel dimensions of sustainable diets associating food systems, public health, environmental sustainability, and culture are presented in this paper. It begins by defining sustainable diets as those that are healthful, have low environmental impacts, are affordable, and culturally acceptable. The discussion includes the history of research on sustainable diets, from initial studies focused on environmental impacts to more recent, comprehensive frameworks that integrate affordability, cultural relevance, and nutritional adequacy as key dimensions of diet sustainability. In addition, the paper highlights recent innovations, such as the Planetary Health Diet of EAT–Lancet and the SHARP model, and the conflicts and optimum trade-offs between sustainability and nutrition, particularly within low- and middle-income countries. Case descriptions of Mediterranean Diet with a focus on Traditional Lebanese Diet, and African Indigenous Foods demonstrate culturally confined dietary patterns associated with sustainability objectives. These examples show that sustainable diets are not a single set of prescriptions, but a series of multiple pathways that are shaped by local food environments, ecological belts, and sociocultural heritages. The paper also describes major policy and governance activities necessary to promote sustainable diets. Finally, the paper addresses measurement challenges and advocates for better indicator options to measure sustainable food systems in all their facets and for participatory and context-specific approaches. The discussion concludes that fairer and culturally diverse inclusion strategies, system change, and political determination are imperative in achieving sustainable diets. Diets able to sustain are posited as agents capable of driving the 2030 agenda, enhancing planetary health and social integrity.
Phlebotomine sand flies are found across multiple regions of Thailand, with growing recognition of their role in transmitting zoonotic pathogens. Environmental factors, including climate variability and vector ecology, may influence their distribution and activity, contributing to the potential spread of zoonotic pathogens in Southeast Asia. However, comprehensive data on sand fly distribution in Thailand remain limited. To address this gap, a systematic review was conducted following PRISMA guidelines. Out of 112 records retrieved, 33 met the inclusion criteria and quality assessment for further analysis. As per results, sand flies are widespread in Thailand, with a high level of species diversity comprising 42 species of 6 different genera. However, several provinces lack data on the presence and distribution of sand flies. Eleven species were identified as the overall abundant species throughout the studies from January 2007 to June 2025 and grouped by abundance: low-abundance species (Sergentomyia barguesae, Sergentomyia phadangensis, Sergentomyia barraudi and Sergentomyia indica), abundant but understudied species (Sergentomyia sylvatica, Sergentomyia anodontis and Neopulpus vietnamensis) and most abundant species (Sergentomyia hodgsoni, Sergentomyia gemmea, Sergentomyia iyengari and Sergentomyia khawi). From the most abundant species, S. khawi tested positive for several pathogens, such as Leishmania spp., Trypanosoma spp., Bartonella spp. and orbivirus. Besides, S. khawi has been shown to exhibit human-biting behaviour through the analysis of blood meal. These findings raise concerns about its potential role in pathogen transmission, especially concerning zoonotic pathogens. However, vector competence remains unproven for some of these pathogens, suggesting the need for further research.
Liberia (West Africa) has an extensive (co)burden of urogenital and intestinal schistosomiasis; each largely restricted to more inland areas. Where urogenital schistosomiasis is endemic, as both disease surveillance and case management are nascent, many women may unknowingly be living with Female Genital Schistosomiasis (FGS). Using a recently developed FGS score card, we appraised FGS score card valuations with point-of-care gynaecological and molecular parasitological evaluations as undertaken within typical primary care settings of four Liberian counties. A total of 400 women, 100 participants from each of four endemic inland counties, underwent a cursory gynaecological examination using a speculum for visible FGS lesions, undertaken by a midwife, and provided a urine sample that was examined by centrifugation with microscopy for Schistosoma ova. Urine-sediments in ethanol were later analysed with a high-resolution melt (HRM) real-time (rt) PCR assay to screen for Schistosoma genetic markers. Using a combination of clinical and parasitological information, overall prevalence of UGS and FGS was <10% and a single case of putative FGS-associated co-infection with Schistosoma mansoni was observed. Participant interviews with the FGS score cards provided an insight into at-risk lifestyle and environmental factors, e.g. women who fished regularly were more likely to present with FGS whereas those who lived > 15 km from a local river were less likely to present with FGS. In this resource-poor setting of Liberia, active surveillance for FGS with either clinical or parasitological methods remains challenging such that sole future use of the FGS score card is most pragmatic for primary care.
According to the principles of the European Pillar of Social Rights, everyone should be entitled to an adequate minimum income sufficient for a healthy diet. Studies show that food insecurity remains a concern in Europe, highlighting the need to determine budgets for adequate nutrition, known as Food Reference Budgets. Previous approaches, based on expert-designed Food Baskets or focus group discussions, are often limited by their normative nature and/or low representativeness.
Design:
To address these problems, this study explores Linear Programming as a novel method to calculate Food Reference Budgets for 26 EU member states. To analyse if Linear Programming could be an adequate tool to calculate future Food Reference Budgets, this method was used to design country-specific food baskets that align with consumption habits and healthy diet requirements. The food baskets were then priced at different levels to determine the cost for healthy diets in 26 European Countries.
Setting:
Germany
Participants:
/
Results:
The results show a positive correlation between optimised healthy and current observed diets for most food groups, indicating that country-specific preferences are reflected in the optimised healthy food baskets. Nevertheless, to meet healthy diet requirements, consumption of vegetables, fruit, fish, and dairy must increase compared to the current observed diets.
At a lower price level, the Food Reference Budgets ranged from 2.38 to 5.71 €/day, depending on the country. With a low-price level (20th percentile), costs for healthy diet accounted for between 5.74 % of income in Luxembourg and 29.00 % in Romania, showing the large differences in affordability between countries.
Conclusion:
Overall, it was concluded that Linear Programming could be a promising approach for determining uniform and comparable European Food Reference Budgets and should be discussed in the context of the EU Commission’s efforts to modernise the European minimum income schemes.
A systematic review and meta-analysis was undertaken to predict the effect of prepartum energy level on postpartum energy metabolism and milk production in dairy cows. In this systematic review, the criteria of PRISMA guidelines were followed: in vivo experimental evaluation of diets with different prepartum energy levels; presentation of initial, final, and/or total results; statement of treatment period including the last 21 days of the prepartum of period; and description of dry matter intake (DMI), milk production, blood parameters and feed efficiency data. A descriptive analysis was performed for better visualization of the data, and Pearson's correlation was used between the collected variables and the prepartum energy intake. The acquired data were subsequently analysed, employing a link function in a polynomial regression model. Prepartum energy intake does not influence DMI or energy balance in the postpartum phase. A higher-energy diet prepartum increased feed efficiency postpartum, accompanied by an increase in blood levels of BHB and NEFA. However, it also resulted in a decrease in milk production and blood glucose.
Growing environmental concerns and the rise of pesticide resistance have prompted a critical need to develop alternatives to synthetic chemical insecticides. In this context, mineral-based products offer a promising solution for integrated pest management. This study examines the potential of a granite dust product as a control agent for two-spotted spider mites, Tetranychus urticae Koch (Acariformes: Tetranychidae), on grapevines, Vitis spp. (Vitaceae). Using two-choice repellency, repulsiveness, and no-choice bioassays involving substrate, foliar, and combined applications, the dust was found to effectively deter mites from moving from control leaves to treated leaves in repulsiveness tests; however, in repellency tests, some but not all mites moved from treated leaves to control leaves. Significantly higher mite mortality was observed across all dust treatments in both bioassays than in control treatments, suggesting that contact exposure to the dust and potentially the accumulation of silica in cell walls in plants treated with rock dust as a substrate amendment could render the cell walls resistant to piercing by spider mite mouthparts. The findings improve the understanding of this product’s potential for pest management.
A major driver of the link between poor water, sanitation and hygiene (WASH) and child stunting is hypothesised to be a sub-clinical condition of the small intestine termed environmental enteric dysfunction (EED). This systematic review aimed to collate research investigating the association between biomarkers of EED and child linear growth outcomes. A systematic search of literature was conducted to identify articles that contain a measure of a domain of EED and its association with linear growth outcomes published up to 31 December 2024. Data pertaining to the measure of EED and child linear growth, as well as study characteristics, were extracted and tabulated. A total of eighty-one studies comprising 31 996 children were included, which suggested that all EED domains, including intestinal damage and repair, intestinal absorption and permeability, microbial translocation, intestinal inflammation and systemic inflammation, were associated with child linear growth. Nuances in the measurement of association were apparent and impacted the observation of significant associations. This review found that whilst the role of EED in child stunting is relatively well established, there are challenges faced in measuring biomarkers in relation to linear growth with possible ambiguities. These issues are discussed in detail to provide aid in interpretation of existing studies and to inform future studies of this kind.
The Mediterranean Diet (Med Diet) has long been shown to be associated with lower cardiovascular mortality in epidemiological studies. However, the direct effect of the dietary pattern on cardiovascular risk factors is less clear. Furthermore, the effect of Med Diet interventions in non-Mediterranean populations on cardiovascular and metabolic risk is variable. A Cochrane Review in 2019 concluded there was low to moderate evidence of a modest benefit but noted that there were still ongoing trials. Since 2019, there have been a number of published trials that have not shown a benefit of the Med Diet over other interventions or usual care. It is possible that dietary factors such as quality or quantity of carbohydrate and energy restriction are more important factors, along with the degree of weight loss, than the Med Diet itself. There are also many other factors that influence the uptake and effectiveness of the Med Diet in populations that have a different traditional or habitual diet. This review paper examines a selection of 20 Med Diet intervention trials specifically looking at clinical outcomes of glucose metabolism: fasting plasma glucose, HbA1c, development of type 2 diabetes or need for hypoglycaemic medications, with or without other cardiometabolic risk factors. These trials are a mix of randomised controlled trials, crossover studies and cohort studies of greater than 8 weeks duration with more than 25 participants. There is heterogeneity in study designs and outcomes, making comparison difficult, but there is no clear benefit of the Med Diet presented.
Ring sea anemones (Cnidaria, Actiniaria) engage in symbiotic associations with octocorals by attaching to their branches and surrounding them with tissue junctions, causing a significant reduction of the host’s coenenchyme. They have previously been reported from the North Atlantic, Western Indian, and Pacific Oceans, from 30 m to aphotic depths, colonising species of sea fans and sea pens in potentially parasitic relationships. Here, we report the first record of ring sea anemones from the Saudi Arabian Red Sea mesophotic waters, living on an octocoral host of the family Ellisellidae at 97 m depth. Through morphological and phylogenetic analyses based on the sequencing of the 12S small subunit rRNA region, we confirmed the identification of these ring sea anemones as Peronanthus sp. (Actiniaria, Amphianthidae). While expanding our knowledge on the geographic range of this genus, this finding emphasises the importance of explorations of coral-associated fauna at mesophotic depths, to better understand their diversity, their relationships with their hosts, and their potential ecological roles within these ecosystems.
Armenia is notable for its wild pear diversity, which includes a large number of globally threatened endemic species. Despite progress in recent studies there still remains, however, a lack of data on the distribution and population sizes of some species, and any threats to them. This information is necessary to assess their conservation status and for the planning and implementation of conservation actions. I present the results of fieldwork in the Vayots Dzor province of Armenia on the globally threatened endemic pear species Pyrus daralagezi Mulk., Pyrus hajastana Mulk. and Pyrus gergerana Gladkova. I report new data on distribution, threats and species biology. I inventoried individual trees, discovering five new individuals of P. daralagezi in Herher sanctuary, rediscovering a population of P. hajastana in its locus classicus 52 years after the first record, and finding a new locality for P. gergerana around the village of Artavan. I make recommendations for the further study and conservation of these threatened pear species.
Time-resolved (TR) intrinsic fluorescence of tryptophan (Trp) provides a wealth of information on the structure and localization of proteins and peptides and their interactions with one another, with drugs, lipid membranes, lipid- and surfactant-based drug delivery systems, et cetera. Intrinsic Trp eliminates the need for labeling and avoids the perturbation of the system by the label; introduced Trp is a rather conservative and small label compared to others. Whereas custom-tailored fluorophores are often optimized for a special technique, Trp can be employed to monitor a wide variety of effects. We address interactions of Trp with surrounding molecules, dynamic quenchers and Förster resonance energy transfer (FRET) acceptors that affect the fluorescence decay. Speed and range of angular motion of Trp are characterized by TR anisotropy. Electrostatic interactions of Trp with charged and polar molecules, including water, are monitored by decay-associated spectra (DAS) or TR emission spectra (TRES) and quantified in terms of TR shifts of the spectral center of gravity. This versatility is a great advantage and, at the same time, comes with a complexity of the behavior that can render it a challenge to interpret the data in detail properly. This review provides an overview of applications of TR fluorescence of Trp bulk samples in biomolecular, biophysical, and pharmaceutical studies. The aim is not only to point out the diversity of the read-out of these techniques, but also critically examine their current use. Therefore, we identify most common technical pitfalls and evaluate the degree of reliability of the interpretational approaches. This should aid a more extensive and meaningful use of TR fluorescence of Trp.
The nematode genus Rhabdias comprises over 100 species of parasitic nematodes that infect amphibians and reptiles, with a wide geographical distribution. To date, 25 species have been reported from the Neotropical region. Despite this diversity, few integrative studies, combining morphological and molecular data have been conducted to characterize species within the genus. Therefore, the main objective of the present study is to describe, through an integrative approach, a new species of Rhabdias found parasitizing the lungs of an anuran with a high concentration of skin toxins, Dendrobates tinctorius, from the Brazilian Amazon. The new species of Rhabdias is characterized by an elongated body, uniform cuticular inflation attenuated at the extremities, 4 submedian lips and 2 lateral lips, a cup-shaped buccal capsule, and an elongated tail. The morphology of the buccal capsule in Rhabdias camposi n. sp. is also unique among Rhabdias representatives, as this morphological character is known so far. Thus, we emphasize that a detailed study of this morphological trait for species of the genus will be crucial for species diagnosis. Molecular and phylogenetic analyses were performed using mitochondrial COI gene sequences. We observed that the new taxon is closely related to Rhabdias waiapi, a parasite of Pristimantis chiastonotus. Rhabdias camposi n. sp. represents the 26th species of the genus reported from the Neotropics in amphibians and the first described from a Dendrobates tinctorius host in Brazil.
Frailty is an ageing-related syndrome of physiological decline, heightening vulnerability and increasing risk of adverse health outcomes. Nutritional deficiencies, particularly in vitamins B9, B12 and D, are prevalent among the elderly owing to physiological changes and reduced food intake. Research suggests a correlation between low levels of these vitamins and an elevated risk of frailty. Vitamin B9, crucial for DNA synthesis and cell division, shows potential in frailty prevention, although evidence regarding supplementation remains inconclusive. Similarly, vitamin B12, essential for nerve function and red blood cell formation, presents conflicting findings regarding its impact on frailty prevention. Vitamin D, essential for bone health and muscle function, is linked to frailty risk, yet studies on the efficacy of supplementation yielded mixed results. The mechanisms involving these vitamins, including their roles in DNA methylation and inflammation regulation, highlight the need for further research to clarify their direct impact on frailty prevention. Maintaining optimal levels of vitamins B9, B12 and D may reduce frailty, but older individuals need a complete approach that includes proper nutrition, physical activity and other preventive measures.
This study, conducted under semi-arid conditions during the 2022 and 2023 growing seasons, aimed to assess the effects of plant growth-promoting rhizobacteria (PGPR) in combination with different irrigation levels and water qualities on safflower (Carthamus tinctorius L.) quality parameters. The irrigation levels were based on 0% (I0 - rainfed), 25% (I25), 50% (I50), 75% (I75) and 100% (I100) of Class A pan evaporation. Two irrigation water qualities were used: recycled wastewater (RW) and freshwater (FW). The PGPR treatments were applied at four frequencies: R0 (control), R1 (once), R2 (twice) and R3 (three times) starting after sowing at 10-day intervals. Seed protein content ranged from 12.0% to 18.1%, with the highest values under I100-R3 and the lowest under I0-R0. Protein content increased with irrigation and bacterial application frequency. Oil content varied between 25.2% and 38.6%, peaking under full irrigation with triple PGPR application (I100-R3), and was generally higher in RW-irrigated plots. SPAD (Soil Plant Analysis Development) values which are an indication for chlorophyll content in the plant ranged from 45.1 to 76.3, with RW-I100 treatments showing the highest readings. Stomatal conductance values varied between 40.5 and 122.0 mmol/m2/s¹, increasing with irrigation level. Overall, combining recycled wastewater and PGPR under sufficient irrigation significantly improved safflower’s physiological and biochemical characteristics. The results suggest that this integrated approach enhances oil and protein content while supporting sustainable water use and crop quality improvement in arid and semi-arid regions.
Sub-Saharan Africa (SSA) is currently undergoing rapid urbanisation, a transition that is closely linked to the adoption of sedentary lifestyles and Westernised dietary habits. This shift has contributed to a substantial rise in obesity and diet-related non-communicable diseases (DR-NCDs), placing a significant strain on already burdened healthcare systems. Among the key modifiable risk factors driving this epidemiological transition are changes in dietary patterns. Western-style diets have been shown to promote inflammation and trigger metabolic and immune dysregulation, factors that underlie the development of DR-NCDs. Conversely, many Tanzanian heritage diets incorporate a diverse array of nutrient-rich foods prepared using techniques that minimise the use of oils, sweeteners and preservatives. These diets predominantly use whole grains, legumes and fruits, foods high in dietary fibre and nutraceuticals. Nutraceuticals are known to have both immunomodulatory and metabolic benefits and could potentially counteract the negative effects associated with Western-style diets. However, the limited scientific documentation of these heritage diets endangers future research into their potential health benefits. This underscores the need for targeted efforts to preserve and promote traditional dietary practices. In this review, we summarise the diversity of heritage diets from four distinct tribes in Northern Tanzania – the Maasai, Chagga, Pare and Hadzabe – who have historically exhibited low rates of DR-NCDs but are now experiencing rapid urbanisation and lifestyle changes. We briefly describe the dietary patterns of these tribes and examine the potential links between the declining usage of traditional dietary practices and the rising prevalence of DR-NCDs in Tanzania.
Declining participation by family childcare home (FCCH) providers in the Child and Adult Care Food Program (CACFP) may stem from inadequate tiered reimbursements for nutritious foods. During the COVID-19 pandemic, federal waivers temporarily eliminated tiers and increased reimbursements. We evaluated provider, sponsor and family perceptions of CACFP benefits and challenges in general and regarding the temporary removal of tiers and increased reimbursement rates.
Design:
From September 2023 to February 2024, FCCH providers, CACFP sponsors and CACFP family recipients in California participated in semi-structured interviews about CACFP benefits and challenges, perception of tiers and the COVID-19 waiver, quality of food and business viability. Thematic analysis was conducted using the immersion crystallisation method.
Setting:
Virtual interviews with California providers, sponsors and families.
Participants:
FCCH providers (n 31), CACFP sponsors (n 10) and CACFP family recipients (n 6).
Results:
Providers and sponsors reported that the higher temporary reimbursement rate positively impacted food budgets and quality. Pandemic-era facilitators of CACFP participation included the higher reimbursement rate, tier removal and a hybrid model for monitoring visits. Benefits beyond the pandemic included nutrition education and supporting child food security. Families valued CACFP for providing a variety of high-quality foods. However, barriers to CACFP participation persist, including administrative burden, inadequate reimbursements, strict regulations and the impacts of the pandemic and inflation.
Conclusions:
Increasing CACFP reimbursements while reducing other participation barriers can better support FCCH providers’ and sponsors’ participation. Supporting FCCH CACFP participation and retention can enhance access to healthy and nutritious meals for children from families with low income.
Nutrition education plays a crucial role in improving the nutritional status of pregnant women, yet evidence of its impact in low-income settings like Ethiopia is limited. This study evaluated the effectiveness of facility-based nutrition education and counseling on pregnant women’s knowledge, dietary practices, and Fe-folic acid supplement use.
Design:
A cluster randomised controlled trial was conducted in Addis Ababa, Ethiopia, involving 683 pregnant women across twenty health centres assigned to intervention or control groups. Antenatal care providers in the intervention group received training on pregnancy nutrition and counseling, while the control group continued standard care per national guidelines. A total of 683 pregnant women were enrolled during their first and second antenatal care (ANC) visits. Mixed-effects linear regression was used to evaluate outcomes.
Study setting:
The study was conducted in Addis Ababa, Ethiopia, from August to December 2017.
Participants:
Pregnant women attending ANC follow-ups and healthcare providers working in ANC units.
Results:
The intervention group demonstrated significant improvements in knowledge, including iodised salt use (difference-in-differences (DID) 23 %), correct Fe-folic acid supplementation duration (DID 68 %) and the need for additional meals during pregnancy (DID 49·9 %). Dietary practices improved with higher dietary diversity (DID 32·3 %), increased dairy consumption (MD 1·2 v. –0·1; DID 1·2 per week) and higher Fe-folic acid supplementation (MD 4·9 v. 1·6; DID 3·2 per week).
Conclusion:
Nutrition education and counseling during ANC visits significantly improved pregnant women’s knowledge and dietary practices. Integrating and strengthening these interventions into routine ANC services could effectively enhance dietary intake and health outcomes.
