This study aimed to examine the comprehension performance difference between children who participated in an augmented reality-based environmental education activity and those who participated in an activity based on coloring pages. The study involved 94 participants, including 47 in the experimental group and 47 in the control group. The researcher-developed Life Cycle Test, consisting of 9 open-ended questions on the water cycle, plant life cycle, and food chain, was used for data collection. In the first phase, children in both groups were asked questions from the Life Cycle Test, and their responses were recorded. Both groups then participated in a coloring activity, with the control group receiving explanations from the teacher about their colored pages and being asked the test questions. In contrast, the experimental group received explanations about using augmented reality applications and 3D visuals before answering the test questions. The pre-test data showed no significant difference in Life Cycle Test scores between the two groups. However, post-test results revealed that the augmented reality intervention better supported children’s understanding than the explanations based on coloring pages. The study’s findings suggest that augmented reality applications can be a powerful tool for enhancing children’s understanding of environmental concepts in early childhood education. Full article

Autism Spectrum Disorder (ASD) is a developmental disorder that comes with co-occurring eating behavior such as limited food varieties, selective food intake, and repetitive eating patterns, contributing to significant challenges for their parents. Many parents find mealtimes difficult and develop anxiety or stress about their child’s nutrition, health, and overall well-being. Hence, parents must equip themselves with the correct awareness and nutrition knowledge. An online open-ended semi-structured interview was conducted among fifteen parents from the community-rehabilitation program center to explore their understanding of nutrition’s importance and the possible coping strategies when facing challenges. The interview sessions were recorded, followed by three researchers’ coding processes. Data were then subjected to thematic analysis. The interview sessions suggested that the parents were aware of the autism trait eating behavior and had a general knowledge about nutrition. However, it was quite challenging when it came to preparation. Nevertheless, the parents are able to manage the challenges with unique kinds of coping strategies. In addition, a complete educational dietary intervention program including psychosocial aspects for parents is recommended for better effectiveness. Full article

Ulcerative colitis patients often attribute their symptoms to specific dietary products. Therefore, even though there are no specific dietary recommendations, these patients commonly have dietary restrictions, often with no consultation from their physician or dietitian, as they believe that they may be beneficial for them. The aim of the study was to analyze the nutritional value of diets and food choices in Polish female ulcerative colitis individuals, in comparison with a pair-matched control sample. The study was conducted on a group of 44 Polish female ulcerative colitis individuals being in remission and 44 individuals within a pair-matched control sample, matched by their age and concurrent diseases, excluding those resulting from ulcerative colitis. The analysis of the diet was based on the self-reported data, including 3-day dietary records (to assess the intake of nutrients and food products), as well as the simple open-ended question about food products excluded from their diet. It was stated that Polish female ulcerative colitis individuals were characterized by a lower energy value of diet (p = 0.0043), accompanied by the higher proportion of total protein (p = 0.0128) than the pair-matched control sample. As a result of a lower energy value for ulcerative colitis individuals, the intake of numerous nutrients was also lower (p < 0.05); however, after recalculation per 1000 kcal, ulcerative colitis individuals were characterized by higher total protein (p = 0.0121), starch (p = 0.0009), and vitamin B₆ intake (p = 0.0319), as well as lower alcohol intake (p = 0.0464). Similarly, as a result of a lower energy value for ulcerative colitis individuals, the intake of numerous foods was also lower (p < 0.05); however, after recalculation per 1000 kcal, ulcerative colitis individuals were characterized by higher meat (p = 0.0058) and potatoes intake (p = 0.0052), as well as lower legumes (p = 0.0301), chocolate sweets (p = 0.0165), and alcoholic beverages intake (p = 0.0062). For chocolate sweets (p = 0.0134) and alcoholic beverages (p = 0.0091), ulcerative colitis individuals were characterized by a higher frequency of declaration of dietary exclusion. At the same time, ulcerative colitis individuals were characterized by a lower frequency of meeting the recommended intake for magnesium (p = 0.0005), iron (p = 0.0189), vitamin E (p = 0.0389), and vitamin B₁ (p = 0.0032). It was concluded that even in remission, there is a risk of inadequate consumption, not meeting the recommended intake, and nutritional deficiencies in the population of female ulcerative colitis patients.

This is an observational study of interstitial glucose (IG) concentrations, IG variability and dietary intake under free-living conditions in 46 females with obesity but without diabetes. We used continuous glucose monitoring, open-ended food recording and step monitoring during regular dietary intake followed by a low-energy diet (LED). Thirty-nine participants completed both study periods. The mean BMI at baseline was 43.6 ± 6.2 kg/m². Three weeks of LED resulted in a mean weight loss of 5.2% with a significant reduction in diurnal IG concentration but with greater glycemic variability observed during LED. The mean 24 h IG concentration decreased from 5.8 ± 0.5 mmol/L during the regular diet period to 5.4 ± 0.5 mmol/L (p < 0.001) during LED, while the mean amplitude of glycemic excursion increased from 1.5 ± 0.7 to 1.7 ± 0.7 mmol/L (p = 0.031). The positive incremental area under the curve at breakfast was significantly larger for LED compared to regular diet. The daily fiber intake and the glycemic index of breakfast meals were significantly associated with the glycemic variability during regular dietary intake. In conclusion, the 24 h mean IG concentration was lower but with more pronounced glycemic variability during LED compared to a regular diet. Full article

The foraging and consumption of wild food plants is a long-standing tradition in many parts of the world and their importance in promoting food security has become more widely debated in recent years. The current study aimed to document, analyze, and interpret the traditional knowledge of non-cultivated vegetables among four Pathan tribes (Alisher Khel, Hadarzai, Haji Khel, and Umarzai) living in the Gadoon Valley, Swabi District, Khyber Pakhtunkhwa, NW Pakistan, and to evaluate how these practices vary among the considered tribal communities. A total of 104 informants were interviewed via a semi-structured, open-ended questionnaire and group discussions. The field survey was conducted from October 2018 to November 2020. Information about local names, growth habit, used plant parts, food/cooking details, medicinal perceptions, availability season, and market prices were collected. The field survey recorded 51 non-cultivated vegetables belonging to 24 botanical families, for which the frequently used plant parts included young leaves, stems, and flowers. The greatest number of use reports was recorded for Colocasia and the highest cultural index value was recorded for Rumex dentatus; the dominant botanical families were Asteraceae and Fabaceae (six species each). Seven species were found to be sold at local and regional markets. Cross-cultural analysis among the four considered tribes showed that the largest number of species was reported by members of the Hadarzai and Umarzai tribes, although most of the quoted wild vegetables were homogenously gathered among all considered communities, with some more idiosyncratic plant uses among the Umarzai group, who have likely been less affected by the erosion of traditional knowledge or possibly have had less access to traded cultivated vegetables. The novelty of the data was assessed by comparing it with the previously published wild food ethnobotanical literature of Pakistan, which showed fifteen new wild vegetables not yet reported in the NW of the country. The recorded food biocultural heritage should be seriously considered in future local development projects aimed at fostering environmental sustainability and food security. Full article

The aquaculture of macroalgae for human consumption and other high-end applications is experiencing unprecedented development in European countries, with the brown algae Saccharina latissima being the flag species. However, environmental conditions in open sea culture sites are often unique, which may impact the biochemical composition of cultured macroalgae. The present study compared the elemental compositions (CHNS), fatty acid profiles, and lipidomes of S. latissima originating from three distinct locations (France, Norway, and the United Kingdom). Significant differences were found in the elemental composition, with Norwegian samples displaying twice the lipid content of the others, and significantly less protein (2.6%, while French and UK samples contained 6.3% and 9.1%, respectively). The fatty acid profiles also differed considerably, with UK samples displaying a lower content of n-3 fatty acids (21.6%), resulting in a higher n-6/n-3 ratio. Regarding the lipidomic profile, samples from France were enriched in lyso lipids, while those from Norway displayed a particular signature of phosphatidylglycerol, phosphatidylinositol, and phosphatidylcholine. Samples from the UK featured higher levels of phosphatidylethanolamine and, in general, a lower content of galactolipids. These differences highlight the influence of site-specific environmental conditions in the shaping of macroalgae biochemical phenotypes and nutritional value. It is also important to highlight that differences recorded in the lipidome of S. latissima make it possible to pinpoint specific lipid species that are likely to represent origin biomarkers. This finding is relevant for future applications in the field of geographic origin traceability and food control. Full article

Cats employ vocalizations for communicating information, thus their sounds can carry a wide range of meanings. Concerning vocalization, an aspect of increasing relevance directly connected with the welfare of such animals is its emotional interpretation and the recognition of the production context. To this end, this work presents a proof of concept facilitating the automatic analysis of cat vocalizations based on signal processing and pattern recognition techniques, aimed at demonstrating if the emission context can be identified by meowing vocalizations, even if recorded in sub-optimal conditions. We rely on a dataset including vocalizations of Maine Coon and European Shorthair breeds emitted in three different contexts: waiting for food, isolation in unfamiliar environment, and brushing. Towards capturing the emission context, we extract two sets of acoustic parameters, i.e., mel-frequency cepstral coefficients and temporal modulation features. Subsequently, these are modeled using a classification scheme based on a directed acyclic graph dividing the problem space. The experiments we conducted demonstrate the superiority of such a scheme over a series of generative and discriminative classification solutions. These results open up new perspectives for deepening our knowledge of acoustic communication between humans and cats and, in general, between humans and animals. Full article

Faced with the novelty of a ²¹²Pb-labeled monoclonal antibody (mAb) for clinical translation, concerns were expressed by the Food and Drug Administration (FDA) regarding ²¹²Pb prematurely released from the mAb-chelate conjugate. The objective of this study was to simulate the worst case scenario of such a failure. Groups of Balb/c mice (n = 9–20) were administered ²¹²Pb by intraperitoneal (0.0925–1.85 MBq) or intravenous (0.0925–1.11 MBq) injection and then euthanized at 7 or 90 days to assess acute or chronic effects. Weights were recorded prior to injection of the ²¹²Pb and at the end of the observation periods. Blood samples were collected for clinical chemistry and blood cell analysis. Thirty tissues were harvested and formalin fixed for histopathological examination. Treatment related effects of the ²¹²Pb were observed in the bone marrow, spleen, kidneys and the liver. Histological alterations in these organs were considered mild to moderate, indicating low grade toxicity, and not considered severe enough to affect function. This data was presented to the FDA and determined to be acceptable. The clinical trial with ²¹²Pb-TCMC-trastuzumab was approved in January 2011 and the trial opened at the University of Alabama at Birmingham (UAB) in July. Full article
