This study aimed to develop and validate a questionnaire that investigates sugar-related eating behaviour, excessive consumption, and addictive-like eating. This questionnaire was validated using a rigorous process assessing content validity, face validity, reliability testing, feasibility testing, and construct validity. Spearman’s correlation coefficients and Cronbach’s alpha were used to assess reliability. Feasibility testing was used to further validate and confirm the scoring/categorisation of ‘low’, ‘medium’, and ‘high’ scorers for use in future research. Exploratory factor analysis and reliability analysis were used to determine underlying latent factors and assess construct validity. Content validity was assessed by health professionals (n = 16), face validity was assessed by the lay public who had no expertise in nutrition or addiction (n = 20). Reliability (n = 54), repeat reliability (n = 50), and feasibility (n = 113) testing were assessed with a sample from the lay public. Spearman’s correlation coefficients were in the range of 0.58–0.91 and were statistically significant (P < 0.001), indicating good temporal stability within the questionnaire. Cronbach’s alpha coefficients were in the range of 0.62–0.93, indicating good internal consistency. Feasibility testing confirmed the use of calculating an ‘average total score’ from the data set and splitting the data set into tertiles: low, medium, and high scorers. Exploratory factor analysis confirmed three latent factors: F1: Compulsive Eating; F2: Comfort Eating; and F3: Withdrawal. Results suggest the questionnaire is highly reliable and was successfully validated. This questionnaire can be used in research to investigate problematic and addictive-like eating behaviour and its effects on ill health.

Allosteric communication is established by networks through which strain energy generated at the allosteric site by an allosteric event, such as ligand binding, can propagate to the functional site. Exerted on multiple molecules in the cell, it can wield a biased function. Here, we discuss allosteric networks and allosteric signaling bias. Networks are graphs specified by nodes (residues) and edges (their connections). Allosteric bias is a property of a population. It is described by allosteric effector-specific dynamic distributions of conformational ensembles, as classically exemplified by G protein-coupled receptors (GPCRs). An ensemble describes the likelihood of a specific (strong/weak) allosteric signal propagating to a specific functional site. A network description provides the propagation route in a specific conformation, pinpointing key residues whose mutations could promote drug resistance. Efficiency is influenced by path length, relative stabilities and allosteric transitions. Through specific contacts, specific ligands can bias signaling in proteins, for example, in receptor tyrosine kinases (RTKs) toward specific phosphorylation sites and cell signaling activation. Thus, rather than the two – active and inactive – states, and a single pathway, we consider multiple states and favored pathways. This allows us to consider biased allosteric switches among minor, invisible states and observable outcomes. Within this framework, we further consider signaling strength and duration as key determinants of cell fate: If weak and sustained, it may induce differentiation; If bursts of strong and short, proliferation.

Planamandibulus nevadensis n. gen n. sp. is a newly discovered exceptionally preserved Laurentian phosphatocopid crustacean described from the upper Windfall Formation (Furongian, Stage 10) in Nevada. Planamandibulus nevadensis has closest affinity with the Baltic and Avalonian taxon Cyclotron. Its occurrence in sedimentary facies associated with dysoxia on the Laurentian paleocontinent fills in a gap in the global distribution of phosphatocopid crustaceans, facilitating a paleoenvironmental synthesis of this Cambrian group. We assess 75 taxa from nine paleocontinental areas spanning Cambrian stages 3 to 10 (~521–486.9 Ma). Comparison of these data with paleoclimate model simulations suggests that phosphatocopid distribution is explained partly by biogeography and ocean temperature patterns. Dabashanella species (e.g., D. hemicyclica Huo et al., 1983) are found across the low paleolatitude (<35°) paleocontinents of East Gondwanan (Australia), South China, and the central Asian terranes, spanning marine shelf carbonates to deeper marine black shale lithofacies, but are absent from mid- and high-paleolatitude sites, suggesting a warmer water preference. A similar warm-water preference is inferred for endemic taxa (e.g., Ulopsis, Parashergoldopsis) of East Gondwana, and perhaps for the newly described Laurentian Planamandibulus. By contrast, the mid- to high-paleolatitude paleocontinents Baltica and Avalonia are characterized by Veldotron, Cyclotron, Bidimorpha, Waldoria, Vestrogothia, Falites, and Trapezilites species, which occur in deep-shelf, cooler-water settings, typically below storm wave base. Hesslandona species sensu lato occur in mid-depth (likely above storm-wave base) warm tropical marine waters but are more typically found in deeper shelf and cooler waters in mid to high paleolatitudes. Phosphatocopids are also associated with sedimentary deposits characteristic of low environmental oxygen concentrations; this is emphasized by a peak in occurrences in the Guzhangian (Miaolingian) and Paibian (Furongian) stages, around the interval of the Steptoean Positive Carbon Isotope Excursion (SPICE) and its associated expansion of anoxic water masses onto shallow marine shelves. Our data compilation and data–model comparison support the environmental preference of phosphatocopids for low-oxygen, but not anoxic, water masses, and the new occurrence of Planamandibulus is consistent with this pattern.

Acute effects of a daily dose of red wine may cause deterioration of visual function; however, there is limited information on healthy individuals. This study aims to investigate acute effects of daily red wine consumption on visual function and retinal microvasculature in healthy young adults through a randomised self-controlled design and to explore the molecular mechanisms using an animal model. In healthy young adults’ study, twenty-seven adults with follow-up at baseline, 0·5 h and 2 h after consuming 300 ml of either red wine or water underwent blood biochemistry, visual function, morphology and blood flow of retinal and choroidal vasculatures, and cerebral blood flow (CBF) evaluation. Acute red wine consumption caused abnormal changes in retinal function (multifocal visual electrophysiology) that preceded changes in vision. Macular vessel diameter index (VDI) increased significantly at 0·5 h but decreased significantly at 2 h, despite increased regional CBF following red wine consumption, which was consistent with increased choroidal thickness and decreased retinal thickness. Animal experiments conducted on Brown Norway rats demonstrated a significant decrease in retinal VDI and vessel area density (VAD) associated with increased reactive oxygen species production following red wine administration, as well as decreased endothelial nitric oxide synthase (eNOS) and increased endothelin-1 (ET-1) levels in the retina. Consequently, red wine consumption caused abnormal changes in retinal function and microvascular constriction in healthy young adults, and an animal model suggested that the underlying mechanism may involve the regulation of eNOS and ET-1 levels in the retina. These findings imply the potential detrimental effects of drinking habits on individuals with retinal ischaemic diseases.

Family meals are positively associated with healthier diets among children and parents. We aimed to deepen the understanding of these relationships by exploring the associations between shared meals and dietary quality among children, fathers and mothers. A subset of parent-child dyads (296 children aged 3–6 years, 103 fathers, 293 mothers) from the DAGIS Intervention baseline assessment was included in this cross-sectional study. The parents reported how often they shared meals with the child and filled in a food frequency questionnaire assessing their child’s and their own food consumption. A Healthy Food Intake Index (HFII) describing dietary quality was calculated for all family members. We used linear regression to investigate the associations between shared meals and the HFII of the children, fathers and mothers. Models were adjusted for child’s age and gender, parent’s age and educational level and number of children in the household. Children whose fathers reported less frequently sharing a weekend lunch with the child had a lower HFII (B estimate –1·58, 95 % CI –2·66, –0·50). The association remained close to statistical significance with adjustments (B estimate –0·99, 95 % CI –2·17, 0·19). A less frequently shared weekend lunch was also borderline significantly associated with lower HFII among the fathers (adjusted model, B estimate –1·13, 95 % CI –2·30, 0·04). Fathers should be encouraged to share meals with their family, since it might have a role in the dietary quality of both children and fathers. Future studies should recognise fathers as important contributors to a healthy home food environment.

A Doppler Sonic Detection and Ranging (SODAR) wind-profiling system was deployed at Jang Bogo Station, Antarctica, during the summer of 2017. The parameters measured by the SODAR system were wind speed and direction averaged for 15 min from 30 m above the surface to 500 m aloft. Additionally, wind measurements obtained from the nearby walk-up tower and automatic weather station (AWS) were also used for additional data and comparison, respectively. The analysis and comparison used hourly average for consistency. The mean wind speed obtained from the SODAR measurement is highly correlated with those from the walk-up tower and the AWS measurements. All three measurements recorded westerlies during all strong wind events but varied during calm periods. The measurements also reveal that Jang Bogo Station experiences lower wind speeds compared to the nearest katabatic confluence region (Inexpressible Island), where the maximum airflow usually occurred. From the hourly averaged data, SODAR only detected a maximum wind speed of 18.1 m s−1. There were 238 occurrences of strong wind events equal to or above 10.8 m s−1 (Beaufort scale 6) from 10 May to 31 October 2017. These occurrences were recorded in 50 out of 175 days analysed in this study. From 10 to 12 June 2017, predominantly south-westerly-westerly winds were recorded at the surface and aloft during two strong wind events. Based on this case study, the boundary layer during calm and strong wind periods was also analysed.

Minimum tillage potato production with rice straw mulching was widely promoted in Vietnam during the 2010s for efficient land use in the winter fallow season. This study evaluates the current adoption status 15 years after its introduction by a qualitative case study consisting of desk review, phone interviews and in-depth interviews, and field observation. Findings reveal that the original practice has been discontinued after initial adoption, primarily attributed to the adoption of rice harvesters and power tillers. The reasons for discontinuation differ from those for other conservation agriculture practices like zero tillage maize or wheat production, emphasizing the importance of tailored approaches for each crop and locality. Some farmers have adapted the method to fit their specific conditions in which the principles of conservation agriculture have been maintained. Those findings underscore the need for continual refinement of agricultural innovations along with socioeconomic and agroecological changes. Drawing on insights from the case of Vietnam, the study proposes a scaling strategy for South Asia where there is increasing interest in promoting potato zero tillage rice straw mulching.

Children with moderate acute malnutrition (MAM) have an increased risk of iron deficiency, anaemia and death from infectious diseases. The iron-regulating hormone hepcidin is increased in inflammation and may be important in regulating iron metabolism in children with MAM. Asymptomatic malaria has previously been associated with elevated s-hepcidin. We assessed the association between inflammation, iron status, anthropometry and malaria and serum hepcidin (s-hepcidin) and evaluated the effect of food supplementation on s-hepcidin in a secondary analysis in 1019 children with MAM from a randomised intervention trial in Burkina Faso. Children received 12 weeks of supplementation of 500 kcal/d as either corn–soy blend (CSB) or lipid-based nutritional supplements (LNS). S-hepcidin was measured at baseline and after 12 weeks. At baseline, correlates of s-hepcidin were determined using Tobit regression. The effect of supplementation was determined using mixed effects Tobit regression. Children with iron deficiency had 82 % (95 % CI 76, 87) lower s-hepcidin than those without, whereas children with acute infection and inflammation had elevated s-hepcidin. Children with symptomatic malaria had 103 % (95 % CI 32, 210) higher s-hepcidin than afebrile children without detectable malaria, while children with recent or asymptomatic malaria had 51 % (95 % CI 35, 63) lower s-hepcidin. S-hepcidin increased 61 % (95 % CI 38, 87) after 12 weeks of food supplementation with 22 % higher (95 % CI 2, 45) concentration in those who received LNS compared with CSB. Expectedly, morbidity and inflammation were associated with higher, and iron deficiency with lower, s-hepcidin. Further studies are needed to corroborate the finding of decreased s-hepcidin in malnourished children with asymptomatic malaria.

The majority of dogs in US animal shelters are of mixed breed. Many animal shelters still use visual identification to assign breed labels, despite research indicating it to be largely inaccurate. Some shelters now include personality descriptions in conjunction with, or instead of, breed labels. However, little is known about the interaction between these factors. Thus, the aim of this study was to experimentally evaluate the impact of breed labels and descriptions on the perceived adoptability of dogs. Participants, recruited both in-person at a shelter and online, were shown ten dog photos, and indicated how likely they were to adopt the dog. The photos were randomly presented under four conditions: (1) photo only; (2) photo with breed label; (3) photo with description; and (4) photo with both a breed label and description. Overall, descriptions significantly increased perceived adoptability, while breed labels decreased it. Certain breed labels, such as ‘Chihuahua mix’, ‘Chow mix’, ‘Jack Russell Terrier mix’, ‘Miniature Pinscher mix’, and ‘Terrier mix’, negatively impacted adoption ratings, while ‘Lab mix’ had a positive effect. Descriptions like affectionate, calm, eager to make you proud, easy-going, friendly, lively, non-dominant, and sociable improved perceived adoptability, whereas energetic reduced adoptability. There were no significant interactions between breed labels and descriptions. Additionally, there was substantial individual participant variability in adoption interest across photos. These findings suggest animal shelters might increase adoption interest in dogs by removing breed labels and including positive descriptions in dog adoption profiles. Such changes may contribute to improved animal welfare by reducing shelter length of stay.

Creatine is a vital bioenergetic compound that remains largely overlooked within food systems despite its well-established role in human health and performance. Unlike creatinine – a downstream breakdown product of creatine metabolism commonly measured as a biomarker of kidney function – creatine functions as an energy buffer, facilitating the rapid regeneration of ATP in tissues with high metabolic demands such as skeletal muscle, brain and heart. Although a portion of daily creatine requirements is met through endogenous synthesis, dietary intake – primarily from animal-source foods – remains essential to maintain optimal physiological levels. Emerging evidence indicates that suboptimal creatine status, or creatine insufficiency, may be widespread, particularly among vegetarians, vegans, older adults, individuals with chronic illness and those with increased energy needs. This paper examines the evolving role of creatine across four domains: its natural occurrence in foods, incorporation into fortified food products, use as a dietary supplement and potential future classification as a pharmaceutical agent. Special emphasis is placed on differences in regulatory status, intended use, dosage, labelling and public health implications. In light of mounting evidence that creatine insufficiency may contribute to adverse outcomes – including impaired cognition, reduced muscular performance and vulnerability to stressors – integrating creatine into food policy and nutrition strategies represents a promising, scalable and preventive approach to improve population health.

Despite being one of the most critical agricultural inputs, chemical fertilizers are often misused by farmers in developing countries due to limited knowledge of proper nutrient management. Understanding current fertilizer application practices is essential for improving efficiency and enhancing crop productivity. This study examines the adoption and determinants of the 4R nutrient stewardship principles (also referred to as best management practices) – applying the right fertilizer source, at the right rate, at the right time, and in the right place (4Rs) – among major cereals (rice and maize) and vegetables (cauliflower) in Nepal. Using a multivariate probit model, we analysed data from 926 surveyed households across 11 districts. Our findings reveal that only 30% of farmers used the right fertilizer source supplying nitrogen (N), phosphorus (P), and potassium (K), while just 7% applied these nutrients at the right time. Additionally, 19% of farmers placed fertilizers correctly, and only 6% applied nitrogen at the right rate. Key factors influencing right nutrient management practices include gender, age, educational level of the household head, access to credit, smartphone ownership, and proximity to cooperative offices. Farmers with small landholdings, more years of farming experience, access to smartphones, and those who borrow agricultural loans are more likely to apply the right rate of nitrogenous fertilizers. The factors contributing to excessive use of nitrogenous fertilizers vary by crop type. Given the low adoption rates of 4R soil nutrient management practices, agricultural policies in Nepal should prioritize promoting these best management practices to enhance fertilizer efficiency, optimize yields, and improve long-term soil health.

Diagnosis of cases of Mycoplasma mastitis is particularly challenging due to their unique biological characteristics, which complicate diagnosis and treatment. Hence, accurate and quick diagnostic tests for early detection of Mycoplasma mastitis are essential to initiate appropriate interventions or culling. The objective of this research is to estimate the diagnostic performance of the molecular microarray assay (MMA) against bacterial culture for the diagnosis of bovine intramammary infections (IMI) with Mycoplasma spp., using a gold standard approach and the Kappa agreement coefficient. A total of 395 quarter milk samples were collected from cows in 31 dairy herds with conventional milking systems in California, USA. Following dairy personnel practices, milk samples were collected from the lactating cows showing abnormal milk characteristics and shipped within 24 hours to the laboratory for bacterial culture and MMA examination. Milk samples with positive growth were confirmed via PCR test to eliminate misdiagnosis of Acholeplasma spp. Eighty-seven cows (22%) were positive for Mycoplasma spp. IMI and the test accuracy was 88.4%. The sensitivity of MMA was 90.8% (95% CI (Confidence Interval): 82.68–95.95), and the specificity was 87.66% (95% CI: 83.46–91.12). The positive predictive value of MMA in these herds was 67.52% (95% CI: 60.51–73.83), and the negative predictive value was 97.12% (95% CI: 94.57–98.49). Calculated Kappa coefficient was 0.70 (95% CI: 0.618–0.778). The high estimates of sensitivity and specificity of MMA suggest its usefulness as a routine and quick test for accurate diagnosis of Mycoplasma spp. IMI in dairy cows. Our findings indicate that MMA holds promise for enhancing the detection of Mycoplasma spp. and could potentially revolutionize diagnostic practices in the dairy industry and supports udder health management.

This study evaluated the effect of different medium-chain to long-chain fatty acid (MCFA:LCFA, M:L) ratios on growth performance, intestinal function, antioxidant capacity and gut microbiota in piglets. A total of 250 piglets were randomly assigned to five groups with five replicates, each containing ten pigs. The diets, containing varying amounts of MCFA-rich coconut oil and LCFA-rich soyabean oil, resulted in M:L ratios of 0, 2·1, 4·2, 8·8 and 33·8 %. Results showed that both final body weight and average daily weight gain increased as the M:L ratio increased (P < 0·05), while the 8·8 % M:L ratio diet exhibited the lowest feed:gain ratio (P < 0·05). As the M:L ratio increased, the contents of superoxide dismutase and glutathione peroxidase were increased, and MDA was decreased in serum (P < 0·05). The 8·8 and 33·8 % M:L diets improved ileal and jejunal morphology (P < 0·05), as indicated by greater villus height and villus height:crypt depth ratios. Furthermore, increasing M:L ratios from 0 to 33·8 % increased expression of tight junction proteins occludin and ZO-1 in the jejunum (P < 0·05). The 33·8 % M:L ratio reduced microbial α-diversity (P < 0·05), while 8·8 % M:L diet significantly increased the abundance of beneficial bacteria (e.g. Lactobacilli, Prevotella) and decreased harmful bacteria (e.g. Escherichia-Shigella, Enterococcus) in the cecum (P < 0·05). In summary, our study found that 8·8 % of dietary M:L ratios significantly improved growth performance, likely through modulating intestinal function, antioxidant activity and gut microbial composition.

To reveal the community structuring mechanism of the pebble interstitial macrofauna, we examined the community structure and its relationship with abiotic environmental factors on a pebble beach in Honshu, central Japan (northwest Pacific). Throughout the year-round survey, we found 66 species from 18 classes in 9 phyla, most of which were either endemic or undescribed species. This is a noticeably higher species diversity compared to the common theory (quite low biodiversity) for pebble beaches and also indicates independence from other environments. Moreover, the communities were divided into five groups through clustering, which were significantly explained by sediment particle size and tidal level using RDA (Redundancy Analysis). However, their interpretabilities were moderate, suggesting that the community structure was moderately controlled by environmental factors. This could be owing to the optimization of the benefit of interspecific ecological niche isolation and the cost of recovering from the disturbance. Consequently, the present study reveals the presence of diverse and unique macrobenthic communities that inhabit the pebble beach environment in Japan and are controlled by the abiotic environmental characteristics of microhabitats.

This study investigated yeast diversity and physicochemical changes during the production of Kargı Tulum cheese, a traditional Turkish cheese. Samples were collected at six key stages, from raw milk to the final product, and analysed for parameters including pH, titratable acidity, dry matter, fat, salt, protein, water-soluble protein and maturation index. During ripening, pH values ranged from 3.03 ± 0.017 to 3.70 ± 0.017, while titratable acidity increased from 0.91% ± 0.16% to 3.33% ± 0.17%. Dry matter and fat content increased significantly, reaching 50.41% ± 1.56% and 33.50% ± 5.41%, respectively. Salt content ranged from 0.58% ± 0.08% to 3.03% ± 0.58%, and protein content from 3.70% ± 0.93% to 20.63% ± 1.16%. The maturation index increased from 5.54% ± 0.71% to 16.26% ± 4.35%, indicating ongoing proteolysis. A total of 42 yeast isolates were phenotypically characterized and grouped by sugar fermentation ability, growth and salt tolerance. Internal transcribed spacer region sequencing identified key yeast species, including Kazachstania unispora, Pichia fermentans, Kluyveromyces lactis, Pichia membranifaciens and Geotrichum candidum. These species play significant roles in cheese maturation, contributing to flavour and texture. The results emphasize the importance of indigenous yeast populations in traditional cheese production and offer insights for improving fermentation and ripening processes to enhance cheese quality.

To determine the long-term effects of transition milk (TRANS), 30 female Holstein calves were allocated to two feeding groups (n = 15/group) after colostrum intake, receiving either 12 L of TRANS of their dam or 12 L of milk replacer (MR) per day. After 5 d of differential feeding, all calves received 12 L of MR/d. Until calving, heifers were weighed monthly. After calving, BW was recorded twice daily after milking. Body condition (BCS) and back fat thickness (BFT) were scored biweekly. Milk yield was recorded twice daily until d 200 in milk. Milk composition (protein, fat, and lactose), as well as somatic cell count (SCC) were analysed biweekly. Blood samples were taken 3 weeks before calving, at the day of calving and 3 weeks thereafter. Oxidative status was assessed as ferric reducing ability of plasma (FRAP) for antioxidative capacity, and as reactive oxygen metabolites via the dROM assay. Oxidative damage of lipids was measured via the thiobarbituric acid-reactive substances (TBARS) assay; peroxidized proteins were assessed using the advanced oxidation protein products (AOPP) assay. Performance until first insemination did not differ between the groups, as well as BW development until the first weeks of lactation. From week 7 of lactation onwards, TRANS had less BW than MR heifers but tended to have a higher BCS. Milk yield and composition did not differ between both treatments. Marker for oxidative stress showed typical patterns of increasing antioxidants before calving and increase in prooxidants after calving in both treatment groups. The results indicate that feeding TRANS in the first 5 days of life had no long-term effects on performance in the first lactation, except for lower postpartum BW in heifers fed TRANS than MR, under the current rearing and management conditions.
