RESUMEN
This study aimed to evaluate the impact of supplementing sodium bicarbonate or a commercial blend of buffering agents (BBA) comprising calcareous calcitic, magnesium oxide, calcareous algae, and sodium bicarbonate on the productive, behavioral and metabolic parameters of Holstein cows fed starchy diets. Over a 60-day trial period, thirty-six multiparous cows with an average milk yield of 38.84 ± 9.24 kg/day and 63.74 ± 18.63 days in milk (DIM), were randomly divided into two groups. The control group (n = 18) received a supplementation of 1.1% dry matter (DM) of sodium bicarbonate (Raudi®, Totalmix, Brazil), while the BBA group (n = 18) was administered with 0.5% DM of a blend of buffering agents (Equalizer®, Nutron/Cargill, Brazil). The mean values of ruminal pH (control 6.80 ± 0.06 and BBA 6.77 ± 0.06; P > 0.05) and volatile fatty acid (VFA) production (control: acetate 62.63 ± 1.29%, propionate 22.99 ± 1.07%, butyrate 14.30 ± 0.52%; BBA: acetate 63.07 ± 1.32%, propionate 23.47 ± 1.10%, butyrate 13.70 ± 0.57%), were similar (P > 0,05) between the two groups. The value of faecal pH was higher (P < 0.05) in the BBA group (6.25 ± 0.02) than the control group (6.12 ± 0.02). Animals treated with BBA exhibited lower (P < 0,05) dry matter intake (DMI) (24.75 ± 0.64 kg/day), higher feed efficiency (FE) (1.64 ± 0.03), and reduced feeding frequency (52.89 ± 3.73 n°/day) than the control group (DMI, 26.75 ± 0.62 kg/day; FE, 1.50 ± 0.03; feeding frequency, 66.07 ± 3.64 n°/day). Milk production remained similar across both groups (control, 39.11 ± 0.92 kg/day and BBA, 39.87 ± 0.92 kg/day; P > 0.05). Notably, the control group displayed a higher (P < 0,05) concentration of milk protein (1.21 ± 0.05 kg/day) than the BBA (1.18 ± 0.05 kg/day) group. The study concluded that both treatments effectively buffered the rumen and mitigated the risk of ruminal acidosis. Moreover, the higher faecal pH in the BBA-treated group suggests potential intestinal action attributable to the synergistic effects of diverse additives with buffering properties. Despite a reduced DMI, BBA-treated animals exhibited improved FE.

BACKGROUND: There is a limited understanding of the dynamic influences that shape infant and young child feeding (IYCF) decisions over time. We conducted an innovative qualitative study to reconstruct IYCF trajectories across early life course phases, in the context of the socioecological model (SEM) and the commercial determinants of IYCF. METHODS: Women of different socioeconomic status were interviewed in two large metropolitan areas in Mexico. Our specific goal was to allow us to better understand if and how the commercial milk formula (CMF) marketing influenced breastfeeding decisions in a complex dynamic way involving the individual, relational, community and societal levels. RESULTS: Hospitals, health professionals, and interactions with social media were key category entry points throughout the prenatal, perinatal, early infancy period and beyond. The CMF industry interfered by engaging a wide array of actors across the different layers of the SEM, most prominently the health care system and the workplace. Through its marketing strategies the CMF operates subconsciously and its messages are most effective when health institutions, health care providers, workplace spaces and social norms are weak in their support for breastfeeding. CONCLUSIONS: The cases in our study highlight how, together with a weak breastfeeding counseling system, and health professionals who lack training in breastfeeding and normal infant behavior, lead to the opportunity for CMF marketing to shape infant feeding, and ultimately to the decision to feed formulas that some mothers were not planning to use and cannot afford.

Current international infant and young child (IYC) feeding recommendations consider nutrition and health but not environmental impacts. Only a handful of countries have dietary guidelines that provide quantitative recommendations for food groups of environmental concern. This study aimed to perform a narrative review of the environmental impacts of commercial milk formula compared with breastfeeding and to analyze the degree to which current country-specific IYC feeding recommendations are aligned with sustainable dietary targets. A mixed-methods review was conducted, including the following: 1) a narrative review of the environmental impact of commercial milk formula compared with breastfeeding and 2) a comparison of recommended intake of meats and dairy for children IYC based on country-specific dietary guidelines compared with the EAT-Lancet Commission dietary targets (ELCT) for children 24 mo or older and adults and if the ELCT should be adjusted for the energy needs of IYC. Formula feeding has a greater environmental impact (â¼48% higher carbon footprint) than exclusive breastfeeding. Available country-specific dietary guidelines for meat and dairy products in children IYC are, in general, at or below the upper limits of the ELCT recommended ranges for older children and adults but are in most cases above the upper limit when adjusting for the energy needs of IYC. Exclusive breastfeeding should be protected and promoted not only as the healthier but also as the most sustainable alternative. Available complementary dietary feeding recommendations of nonprocessed meat and dairy fall below current ELCT for older children and adults. Given that IYC require a more nutrient-dense diet than older children and adults and considering the small quantities they consume, we recommend using the unadjusted ELCT as reference for IYC feeding while specific international consumption recommendations are developed for this age group.
RESUMEN
Background: Given the role of commercial determinants on sugar consumption and health, this study aimed to describe lobbying practices of the ultra-processed sugary food and drinks industries in Chile between 2014 and 2022. Methods: Official meetings between ultra-processed sugary food and drinks industries and related commercial actors and Chilean government officials were obtained from the Chilean Lobby Registry. Relevant commercial names were initially identified based on their market share and expanded iteratively based on information from relevant meetings. Qualitative analysis followed a deductive-inductive approach using the Corporate Political Activity Model to identify and classify objectives, framing and action strategies. Findings: From 237 records identified, the Ministries of Health, Social Development, and Economy were the most frequently lobbied. Industry representatives sought to achieve their short- and long-term objectives by targeting a diverse range of authorities, including Ministers and Under-secretaries, using different strategies. Framing strategies focused on presenting sugary food and drinks industries as socially responsible and legitimate policy actors and criticised public health initiatives as 'bad solutions'. Action strategies aimed to influence policymaking and nurture corporate reputations. Interpretation: Extensive lobbying took place by the sugary food and drinks industries between 2014 and 2022, a period when major public health policies were being discussed in Chile. Lobbying strategies varied to meet industry objectives and targeted a diverse range of government institutions including high-ranking officials. Tighter regulations to stop inappropriate industry influence in public health policymaking are urgently required. Funding: Agencia Nacional de Investigación y Desarrollo (Chile)-PhD Scholarship.

RESUMEN
In this study, nine commercial ice creams and four prototypes were assessed. For the sensory analysis, quantitative descriptive analysis (QDA), and temporal dominance of sensations (TDS) methodology were used. According to the QDA results, full-composition ice cream showed significantly higher differences (p < .05) in terms such as vanilla and sweet flavors, brightness, creamy texture and appearance, and viscosity, exhibiting longer melting times. Functional ice creams showed significantly higher differences (p < .05) in terms like viscosity, creamy texture, and appearance. On the other hand, agave fructans in prototype ice creams were found to be able to reduce fat, but not fat and sugar simultaneously, showing a significant decrease (p < .05) in terms such as hardness, crystallized texture, gummy texture, and porosity. Based on the PCA results, the analysis accounted for 75.28% of data variability. Full-composition ice creams and one functional ice cream were related to terms such as viscosity, fatty sensation, creamy texture and appearance, dense, gummy, among others. The rest of the commercial ice creams were related to vanilla and caramel flavor and smell, artificial aftertaste, aerated, porosity, among others. Prototype ice creams were related to hard texture, salty and milk flavor, and crystallized texture. Based on the results of the TDS method, all formulations were found to be significantly dominant (5%) in terms such as vanilla flavor and sweet flavor at the beginning of the test. Formulations containing butyric fat and/or vegetable fat, or agave fructans were significantly dominant (5%) in fatty sensation.

Global warming has significantly altered fish distribution patterns in the ocean, shifting towards higher latitudes and deeper waters. This is particularly relevant in high-latitude marine ecosystems, where climate-driven environmental changes are occurring at higher rates than the global average. Species Distribution Models (SDMs) are increasingly being used for predicting distributional shifts in habitat suitability for marine species as a response to climate change. Here, we used SDMs to project habitat suitability changes for a range of high-latitude, pelagic and benthopelagic commercial fish species and crustaceans (10 species); from 1850 to two future climate change scenarios (SSP1-2.6: low climate forcing; and SSP5-8.5: high climate forcing). The study includes 11 Large Marine Ecosystems (LME) spanning South America, Southern Africa, Australia, and New Zealand. We identified declining and southward-shifting patterns in suitable habitat areas for most species, particularly under the SSP5-8.5 scenario and for some species such as Argentine hake (Merluccius hubbsi) in South America, or snoek (Thyrsites atun) off Southern Africa. Geographical constraints will likely result in species from Southern Africa, Australia, and New Zealand facing the most pronounced habitat losses due to rising sea surface temperatures (SST). In contrast, South American species might encounter greater opportunities for migrating southward. Additionally, the SSP5-8.5 scenario predicts that South America will be more environmentally stable compared to other regions. Overall, our findings suggest that the Patagonian shelf could serve as a climate refuge, due to higher environmental stability highlighting the importance of proactive management strategies in this area for species conservation. This study significantly contributes to fisheries and conservation management, providing valuable insights for future protection efforts in the Southern Hemisphere.

BACKGROUND: The commercialization of non-timber forest products (NTFPs) provides income for rural indigenous households. The integration of NTFPs into formal markets tends to intensify management practices to ensure production and monetary benefits. However, more research is needed to understand the motivations for managing of commercialized species. We examine the influence of social, ecological, and economic factors on traditional management and how they drive the adoption of more or less intensive practices for subsistence and commercially traded NTFPs. METHODS: The study was conducted in the Nahua community of Ixtacxochitla, in the Sierra Negra of central Mexico, where we conducted free lists and semi-structured interviews in 32% of the 88 households to assess socio-ecological variables related to management practices. In addition, we interviewed local traders to assess commercial variables used in a cost-benefit model to calculate the net annual income of commercialized species. Non-metric multidimensional scaling was used to analyze relationships between socio-ecological variables and management practices. We also explored the relationship between management and commercial factors using principal component analysis. RESULTS: We recorded 64 plant and mushroom species of NTFPs used for medicinal, ornamental, ceremonial, and edible purposes, 36 of which are commercialized in the municipal market of Coyomeapan. The commercialized species generated an average annual net income of MXN 67,526 (USD 3924) per family, with five species contributing the most. Species both used for both subsistence and commercialization were managed through incipient in situ gathering, tolerance in ex situ anthropogenic areas, and intensive protection and propagation efforts in ex situ environments. Even the five species with the highest commercial returns were managed across this gradient of practices. Key factors influencing the adoption of more intensive species management practices were feasibility of management, type of species use, ecological abundance, frequency of consumption, and cultural importance. CONCLUSIONS: The intensification of NTFPs management is not solely driven by the commercial value of the products or the level of income generated. Instead, the interaction between socio-ecological and economic factors determines the extent of management practices. The main constraint to the implementation of intensive practices has been the inability to manage species outside their natural habitats, despite their cultural significance and frequent consumption. Understanding the factors involved in the harvesting of NTFPs can serve as the basis for future research aimed at analyzing the conditions for successful and sustainable NTFPs commercialization.

Omega-3 fatty acids, such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), offer numerous health benefits. Enriching these fatty acids in fish oil using cost-effective methods, like lipase application, has been studied extensively. This research aimed to investigate F. solani as a potential lipase producer and compare its efficacy in enhancing polyunsaturated omega-3 fatty acids with commercial lipases. Submerged fermentation with coconut oil yielded Lipase F2, showing remarkable activity (215.68 U/mL). Lipase F2 remained stable at pH 8.0 (activity: 93.84 U/mL) and active between 35 and 70 °C, with optimal stability at 35 °C. It exhibited resistance to various surfactants and ions, showing no cytotoxic activity in vitro, crucial for its application in the food and pharmaceutical industries. Lipase F2 efficiently enriched EPA and DHA in fish oil, reaching 22.1 mol% DHA and 23.8 mol% EPA. These results underscore the economic viability and efficacy of Lipase F2, a partially purified enzyme obtained using low-cost techniques, demonstrating remarkable stability and resistance to diverse conditions. Its performance was comparable to highly pure commercially available enzymes in omega-3 production. These findings highlight the potential of F. solani as a promising lipase source, offering opportunities for economically producing omega-3 and advancing biotechnological applications in the food and supplements industry.

The tomato (Licopersicon esculentum Mill.) is considered to be one of the products with the highest demand due to its nutritional value; however, it is susceptible to infection by fungi during its pre- and postharvest stages. In this research, three commercial products (1% Citrocover, 1% Citro 80, and 0.002% Microdyn) and two coatings based on 1.0% chitosan/0.1% lime or 0.1% orange essential oils were evaluated in vitro and on Saladette tomatoes that were previously inoculated with four postharvest fungi. The application of the commercial citrus-based product Citrocover was highly effective in reducing the in vitro development of Aspergillus flavus, Fusarium oxysporum, and Colletotrichum gloeosporioides, but not Rhizopus stolonifer. The sanitizer Microdyn promoted infections with most fungi. Citrus-based products were effective in reducing infections with A. flavus in the tomatoes during storage. Overall, mycotoxin production was very low for all treatments. The use of commercial citrus-based products and coatings did not alter the weight loss, firmness, or total soluble solid contents of the treated tomatoes. The changes observed were, rather, associated with the normal ripening process of Saladette tomatoes. The commercial citrus-based products satisfactorily controlled the in vitro growth of the fungi Aspergillus flavus, Fusarium oxysporum, and Colletotrichum gloeosporioides.
RESUMEN
BACKGROUND: To the best of our knowledge, studies on the relationship between spectral energy distribution and the degree of perceived twang-like voices are still sparse. Through an auditory-perceptual test we aimed to explore the spectral features that may relate with the auditory-perception of twang-like voices. METHODS: Ten judges who were blind to the test's tasks and stimuli rated the amount of twang perceived on seventy-six audio samples. The stimuli consisted of twenty voices recorded from eight CCM singers who sustained the vowel [a:] in different pitches, with and without a twang-like voice. Also, forty filtered and sixteen synthesized-manipulated stimuli were included. RESULTS AND CONCLUSIONS: Based on the intra-rater reliability scores, four judges were identified as suitable to be included in the analyses. Results showed that the frequency of F1 and F2 correlated strongly with the auditory-perception of twang-like voices (0.90 and 0.74, respectively), whereas F3 showed a moderate negative correlation (-0.52). The frequency difference between F1 and F3 showed a strong negative correlation (-0.82). The mean energy between 1-2 kHz and 2-3 kHz correlated moderately (0.51 and 0.42, respectively). The frequency of F4 and F5, and the energy above 3 kHz showed weak correlations. Since the spectral changes under 2 kHz have been associated with the jaw, lips, and tongue adjustments (i.e. vowel articulation) and a higher vertical laryngeal position might affect the frequency of all formants (including F1 and F2), our results suggest that vowel articulation and the laryngeal height may be relevant when performing twang-like voices.
RESUMEN
BACKGROUND: The exploitative marketing of commercial milk formula (CMF) reduces breastfeeding, and harms child and maternal health globally. Yet forty years after the International Code of Marketing of Breast-Milk Substitutes (The Code) was adopted by WHO member states, many countries are still to fully implement its provisions into national law. Furthermore, despite The Code, worldwide CMF markets have markedly expanded. In this paper, we adopt Brazil as a case study to understand the power of the baby food industry's marketing and corporate political activity, and how this influences the country's 'first-food system' in ways that promote and sustain CMF consumption. METHODS: We used a case study design, drawing data from from documents and key informant interviews (N = 10). RESULTS: Breastfeeding rates plummeted in Brazil to a historic low in the 1970s. A resurgence in breastfeeding from the mid-1980s onwards reflected strengthening political commitment for a national policy framework and breastfeeding protection law, resulting in-turn, from collective actions by breastfeeding coalitions, advocates, and mothers. Yet more recently, improvements in breastfeeding have plateaued in Brazil, while the industry grew CMF sales in Brazil by 750% between 2006 and 20. As regulations tightened, the industry has more aggressively promoted CMF for older infants and young children, as well as specialised formulas. The baby food industry is empowered through association with powerful industry groups, and employs lobbyists with good access to policymakers. The industry has captured the pediatric profession in Brazil through its long-standing association with the Brazilian Society of Pediatrics. CONCLUSION: Brazil illustrates how the baby food industry uses marketing and political activity to promote and sustain CMF markets, to the detriment of breastfeeding. Our results demonstrate that this industry requires much greater scrutiny by regulators.

Corporate influence in policy and decision-making is an important public health concern. This Health Policy paper reviews Ecuador's child malnutrition strategy instruments, approved between 2020 and 2023, to identify how private interests are becoming legally integrated into the public sector. Evidence indicates that recent changes are enabling corporations to promote their brands, gain tax deductions, oversee public policy and set priorities, allocate resources, and decide on implementation of the country's child malnutrition strategy. Further, corporate representatives are active members of an advisory council, free from scrutiny or accountability, while being privy to undisclosed government information. Moreover, a UN agency (the World Food Program) engaged in corporate promotion of highly processed foods, illustrating the breadth of Ecuador's corporate influence scheme. Improved regulations should set clear limits to the influence of food and beverage industries in national nutrition policy, while following transparency laws in the composition and operation of Ecuador's child malnutrition strategy and related efforts.
RESUMEN
Temporary immersion systems (TIS) are technological tools that support plant micropropagation. Given their high efficiency in the in vitro propagation of shoots, a current goal is to update the protocols addressing micropropagation in semisolid culture systems to protocols involving TIS. To this end, different parameters have been evaluated, including TIS types and designs, immersion times, immersion frequencies, and volume of medium per explant, among other characteristics. This has resulted in the improved production of propagules of plants of economic interest and the production of physiologically upgraded plants with high percent survival during acclimatization. TIS are specialized culture flasks that provide countless advantages during the commercial micropropagation of plants.

The cultivation of vanilla (Vanilla planifolia) is of economic interest because vanillin is extracted from the fruits of this species. Vanillin is a natural flavoring highly valued in the food market. However, there is a short supply of propagules available for establishing commercial plantations and good-quality plants with phytosanitary certification. Plant tissue culture represents a viable option to supply large amounts of healthy plants to vanilla producers. In addition, the use of temporary immersion systems will allow commercial scale-up and the establishment of biofactories dedicated to in vitro vanilla propagation. This chapter describes a large-scale micropropagation protocol for vanilla using temporary immersion bioreactors (TIB).

In vitro propagation protocols that include temporary immersion systems are available for the most economically important plant species. However, these have not been established yet for multiple species. Having protocols validated by the scientific community guarantees the success of the mass production of commercial propagules. Besides, adequate TIS parameters should be established for each plant species to improve the efficiency of micropropagation processes. This book compiles basic and applied aspects of temporal immersion systems used for in vitro plant micropropagation, along with several detailed protocols already established, which may be used as a guide by those interested in this technique, including laboratory technicians, scientists, and other professionals.

This study was investigated to assess the effects of different traditional and commercial aqua feed on proximate composition, growth performance and survival rate of Labeo rohita reared in the composite semi-intensive culture system. The aqua feeds of various companies (AMG, Supreme, Aqua, Star Floating, Hi-Pro and Punjab feed) used as commercial feed. Farm made feeds were maize gluten and rice polish. For confidentiality, these feeds were randomly given code labels T1, T2, T3, T4, T5, T6, T7 and T8 which were only known to investigating staffs. There were two replicates for each treatment. In this experiment, higher growth rate was observed in T3 as compared to other treatments. Lesser weight gain was observed in the T1 ( 270.30 ± 0.5 ). The maximum body length ( 19.25 ± 2.19) was found in T3. Similarly, the minimum body length (5.97 ± 2.94) was seen in T2. FCR ratio (2.36 ± 0.01 ) was recorded in T3. Simultaneously, FCR (1.86 ± 0.002 ) was also recorded in T4 that is the perfect ratio for farmers. Higher SGR was noted in T3 (1.62 ± 0.05 ). Overall, T4 showed lesser SGR (1.05 ± 0.001 ). T4 showed the higher crude protein ( 28.66 ± 0.24 % ). In the body composition higher level of fat content was recorded in T3 ( 5.46 ± 0.33 %). These outcomes also proved that the rise in the dietary protein level and lipid content can improve the fish's body crude fats and protein level. Thus, based on growth performance, survival and proximate composition. It is concluded that T3 and T4 may be recommended for commercial culture of L. rohita.
O objetivo deste estudo foi determinar os efeitos de diferentes rações aquáticas tradicionais e comerciais na composição centesimal, o desempenho de crescimento e a taxa de sobrevivência de Labeo rohita criado em sistema de cultivo semi-intensivo composto. Foram utilizadas diversas marcas de ração aquática comercial, das seguintes empresas: AMG, Supreme, Aqua, Star Floating, Hi-Pro e Punjab feed,. As rações, à base de glúten de milho e polimento de arroz, foram produzidas na fazenda. Para fins de confidencialidade, esses feeds receberam aleatoriamente os rótulos de código T1, T2, T3, T4, T5, T6, T7 e T8, que eram conhecidos apenas pelos funcionários da investigação. Houve duas repetições para cada tratamento. Neste experimento, maior taxa de crescimento foi observada em T3 em comparação com outros tratamentos. O menor ganho de peso foi observado no T1 ( 270,30 ± 0,5 ). O comprimento máximo do corpo ( 19,25 ± 2,19) foi encontrado no T3. Da mesma forma, o comprimento mínimo do corpo (5,97 ± 2, 94) foi observado em T2. A razão FCR (2,36 ± 0,01) foi registrada em T3. Simultaneamente, a TCA (1,86 ± 0,002 ) também foi registrada em T4 que é a razão perfeita para os agricultores. Maior SGR foi notado em T3 (1,6 2 ± 0,05 ). De maneira geral, T4 mostrou SGR menor (1,05 ± 0,001 ). T4 mostrou a proteína bruta mais alta (28,66 ± 0,24% ). Na composição corporal, o maior teor de gordura foi registrado no T3 ( 5,46 ± 0,33 %). Esses resultados também mostraram que o aumento do teor de proteína e lipídio na dieta pode melhorar a gordura corporal bruta e o nível de proteína. Assim, com base no desempenho de crescimento, sobrevivência e composição aproximada, conclui-se que T3 e T4 podem ser recomendados para cultivo comercial de Labeo rohita.

Introduction: Breastfeeding (BF) is considered an essential component of optimal care for child health and development. In the past two decades, global data have shown improvements in some, but not all, BF indicators. Despite these positive changes sales and per capita intake of commercial milk formula (CMF) have increased globally. The CMF industry invests millions of dollars in marketing, which targets families and healthcare professionals (HCP). In Mexico, more than half of the mothers (53%) who feed their infants with CMF chose their Brand on the recommendation of HCP. Understanding the reasons behind the current recommendations for the use of CMF by HCP is important for the design of BF interventions. The primary objective of this study was to explore Mexican HCP' beliefs, attitudes, perceptions, and practices about early infant feeding practices, and reasons for recommending CMF. The secondary objective was to explore pregnant women and mother's perceptions of the infant feeding recommendations they received from HCP, and of the factors that influenced their infant feeding decisions. Methods: The study was based on a secondary qualitative data analysis of a WHO/UNICEF multi-country study. We analyzed focus group discussions (FGDs) and in-depth interviews (IDIs) from Mexico. Data were collected through convenience sampling in Mexico City and Guadalajara. HCP (n = 34) analysis was based on IDIs, and pregnant women or mothers of children 0-18 months (n = 74) on FGDs and IDIs. Results: Through a thematic analysis, we identified the socioecology of BF and triangulated HCP and women's accounts. HCP, pregnant women, and mothers recognized that several factors might have influenced their infant feeding decisions including healthcare facilities' policies and maternal work conditions. Although HCP believed that BF is the best way to feed newborns and young children, they routinely recommended CMF. On the other hand, pregnant women and mothers had a strong belief that BF is the best way to feed their babies. However, when women sought support from HCP, the latter often recommended switching to CMF. Discussion: This study highlights the discordance between HCP perceptions and mothers' experiences of HCP recommendations about infant feeding. Our findings support a national call for policy actions.

Scientific evidence exists about the association between neurological diseases (i.e., Parkinson's disease, Alzheimer's disease, amyotrophic lateral sclerosis (ALS), multiple sclerosis, depression, and memory loss) and oxidative damage. The increasing worldwide incidence of such diseases is attracting the attention of researchers to find palliative medications to reduce the symptoms and promote quality of life, in particular, in developing countries, e.g., South America and Africa. Among potential alternatives, extracts of Cannabis Sativa L. are suitable for people who have neurological disorders, spasticity, and pain, nausea, resulting from diseases such as cancer and arthritis. In this review, we discuss the latest developments in the use of Cannabis, its subtypes and constituents, extraction methods, and relevant pharmacological effects. Biomedical applications, marketed products, and prospects for the worldwide use of Cannabis Sativa L. extracts are also discussed, providing the bibliometric maps of scientific literature published in representative countries from South America (i.e., Brazil) and Africa (i.e., South Africa). A lack of evidence on the effectiveness and safety of Cannabis, besides the concerns about addiction and other adverse events, has led many countries to act with caution before changing Cannabis-related regulations. Recent findings are expected to increase the social acceptance of Cannabis, while new technologies seem to boost the global cannabis market because the benefits of (-)-trans-delta-9-tetrahydrocannabinol (Δ9-THC) and cannabidiol (CBD) use have been proven in several studies in addition to the potential to general new employment.
RESUMEN
This study aimed to investigate trends and concerns related to the commercialization of dogs in Brazil. The authors analyzed 1,500 ads for the sale of Miniature Schnauzer, Chihuahua, and German Spitz breeds using the methodology of hedonic price analysis. Marginal and relative values of attributes were calculated for puppy sex, coat, age, pedigree, vaccination and deworming, seller type and region, using ordinary least squares. The most valued attributes for each breed were identified as selling by kennels, pedigree, and coat color. The results suggest that this market niche is willing to pay for guarantees of better dog breeding, which represents an opportunity for the development of certification labels for origin and good practices for kennels. Such labels could become an effective strategy to ensure greater transparency and better welfare standards in the Brazilian dog market. This study also provides valuable insights for the development of guidelines and public policies aimed at improving animal welfare and reducing information asymmetry in the pet market.
RESUMEN
Cryostructured gels, better known as cryogels, are a very important emerging class of biomaterials that have diverse applications in food preservation. This work shows a novel alternative to prepare a cryostructured composite coating made from a blend of xanthan, bovine collagen, and oregano essential oil. The composite coating was suitably applied onto the surface of preservative-free biscuits which were stored for 15 days at 25 ± 2°C and 52% ± 1% relative humidity. The evaluation focused mainly on the changes in the physicochemical, textural, and microbiological characteristics of the biscuits. It was found that the coated samples significantly (p < 0.05) decreased moisture absorption, water activity, and fungal growth. However, the composite coating minimally impacted the quality of biscuits in terms of color, texture profile, and surface microstructure. Overall, the cryostructured composite coating constitutes an advance in technological strategies aimed at the preservation of baked products. This will allow, in the future, the development of novel coatings on bakery products to generate new trends in the conservation of their properties and extension of shelf life. This could be achieved through the implementation of new technologies in the food industry, with the aim of making them more environmentally friendly and contributing to the generation of less plastic waste. PRACTICAL APPLICATION: The study and application of cryogels, as innovative systems in the food industry, allow to expand and diversify the materials that can function as coatings to maintain some quality characteristics, in this case in bakery products, so it is important to analyze their effects and consider them to improve conservation processes.
