Evaluating Dietary Red Lentil Screenings on Performance, Antioxidant Status, Caecal Environment, and Intestinal Morphometric Features in Rabbits

Among the goals of global environmental policies, one is to achieve a critical rethinking of the agro-industrial production chain aimed at enhancing its sustainability and resilience while addressing its environmental impact. Lentils are widespread worldwide and are consumed as part of traditional dishes, and their health-promoting benefits are currently well recognized. Their industrial processing for human consumption implies the generation of different by-products which can be used as promising alternative feedstuff. Calling for the future sustainable development of rabbit farming, the present study questions the dietary inclusion of red lentil screenings (RLS) as an upcycling strategy for this by-product, as well as to ease the challenges faced by the rabbit-farming system. A total of 120 male Bianca Italiana breed growing rabbits aged 42 days were allotted to three dietary treatments containing different levels of RLS: 0 (RLS0), 5 (RLS5), or 10% (RLS10), respectively, for 6 weeks. At 84 days (slaughter age), meat, plasma, and intestinal samples were collected. The RLS inclusion showed no adverse effects on growth performance. However, significant differences were found in the meat fatty acid profile, where both RLS5 and RLS10 groups showed reduced C18:0 percentage and higher MUFA content owing to an increase in C18:1 n-9; moreover, RLS5 showed a significant increase in C16:1 trans. On the other hand, only RLS10 recorded a significant reduction in the PUFA total content due to decreased single unsaturated fatty acid (C18:2 n-6; C20:3 n-6; C22:5 n-3). Dietary RLS significantly decreased serum total cholesterol, LDL, and HDL, along with an enhancement of the overall serum antioxidant capacity. The results regarding the rabbit caecal characteristics and microbial population were found to be similar among the groups. However, referring to histomorphometric measurements, both RLS5 and RLS10 groups displayed significant increases in villus height and an improved villus height to crypt depth ratio. In conclusion, up to 10% RLS in the diets rabbits can be considered an effort-effective feeding strategy to modulate rabbit meat fatty acid profiles, to enhance the endogenous antioxidant capacity, and to improve the serum lipid profile and intestinal morphology.

Endurance Exercise Training Alters Lipidomic Profiles of Plasma and Eight Tissues in Rats: a MoTrPAC study.

Endurance exercise training (ExT) induces metabolic, structural, and functional adaptations via lipidomic modifications, yet the systematic elucidation of lipidome alterations in response to ExT remains incomplete. As a part of the Molecular Transducers of Physical Activity Consortium (MoTrPAC), we leveraged non-targeted and targeted lipidomics for the systematic discovery of lipid alterations in the brown adipose tissue, heart, hippocampus, kidney, liver, lung, skeletal muscle gastrocnemius, subcutaneous white adipose tissue, and plasma in response to 1, 2, 4 or 8 weeks of ExT in 6-month-old male and female Fischer-344 rats. This study demonstrates that these tissues, each with distinct lipidomic features, underwent dynamic, sexually dimorphic lipid remodeling. Exercise trained animals showed reduced whole-body adiposity and improved cardiorespiratory fitness, along with enhanced utilization of lipid stores and dynamic triacylglycerol remodeling compared to sedentary controls in all tissues except hippocampus. They also showed modifications in phospholipids, lysophospholipids, oxylipins, and ceramides in several tissues. Coordinated changes across tissues reflect systemic tissue communication, with liver-plasma-heart connection potentially playing a key role in systemic lipid metabolism during ExT. These data will improve our understanding of lipid-associated biological processes underlying the health-promoting benefits of ExT.

Unlocking the Cardiovascular Benefits of Walnuts: Insights on Molecular Mechanism From Animal Studies.

The health-promoting benefits of walnut consumption are substantially ascribed to its fatty acid (FA) profile, which is rich in polyunsaturated FA with an exceptionally high n-3 to n-6 ratio. There are also phytonutrients in walnuts that are linked to health welfare. This review article integrates all studies on the effects of walnuts on the cardiovascular system performed on experimental animals, and thus is a source of data on the mechanisms underlying the observed effects. These studies, which are very diverse in experimental design, indicate that a diet enriched with walnuts or treating animals with walnut extract or chemical constituents of walnuts, has many favorable effects on heart and vascular system function. The cardiovascular effect of walnuts depends on the metabolic status of the organism. Among the cardiovascular effects of walnuts is that they improve the FA profile in the circulation and heart in favor of n-3 polyunsaturated FAs. In addition, a favorable effect on triglyceride and cholesterol status, which reduces cardiovascular disease risk, is observed. Intake of walnuts promotes FA catabolism and has anti-inflammatory, antioxidant, and antiarrhythmic effects. Walnuts also have a beneficial effect on vascular tone, accompanied by a decrease in blood pressure and reduced risk for atherosclerosis. In conclusion, studies on experimental animals encourage the consumption of walnuts as a simple, convenient approach to improve cardiovascular health.

Glycosylation of chrysin with β-d-glucose tetraacetate (LQFM280) enhances its in vitro and in vivo neuroprotective effects against the toxicity induced by 3-nitropropionic acid.

Chrysin (CHR) is a naturally occurring flavonoid found in the human diet, recognized for its potential in preventing neurodegenerative diseases. However, its limited water solubility restricts its bioavailability and therapeutic applications. To address this issue and bolster the neuroprotective properties of CHR for potential nutraceutical or medicinal use, we investigated a novel compound, LQFM280, formed by conjugating CHR with β-d-glucose tetraacetate. We conducted both in vitro (using SH-SY5Y cells, mutant STHdhQ111/Q111 cells, and wild-type STHdhQ7/Q7 cells), and in vivo (mice) neurotoxicity experimental model induced by 3-nitropropionic acid, which mimic biological changes akin to Huntington's disease in humans. Compared to non-glycosylated CHR, LQFM280 showed superior in vitro effects in preventing neurotoxicity caused by increased mitochondrial vulnerability due to mutant huntingtin. In vivo findings demonstrated that LQFM280 has heightened efficacy in mitigating weight loss, memory and locomotor impairment, oxidative stress, and disruptions in the antioxidant defense system, as well as succinate dehydrogenase, and cholinesterase activities induced by 3-nitropropionic acid. These findings underscore the significant enhancement of chrysin's neuroprotective effects through glycosylation with β-d-glucose tetraacetate, positioning it as a promising candidate for use as a nutraceutical or food supplement to promote health benefits.

Exploring the pathways of urban green space exposure on respiratory health: An empirical study in Nanjing, China

Pathways of association between green space (GS) exposure and respiratory health continue stimulating scholars' research interest. However, the mechanisms underlying the multidimensional association between GS exposure and respiratory health remain to be clarified. Therefore, this study aimed to construct a research framework for exploring the mechanisms affecting the hypothesized pathways (physical activity, air pollution) based on the dynamic quantification of multidimensional exposure indicators (spatial and visual exposure). This study used urban green spaces in Nanjing, China, as sample sites for a pilot experiment. The parallel mediating effect of GS exposure on respiratory health through physical activity and air pollution was explored by partial least squares (PLS) modeling, and the effect of differences in GS exposure levels on this parallel mediating model was explored. The results showed that a dynamic monitoring system of multiple indicators is more conducive to characterizing the actual GS exposure of the population. Promoting physical activity and reducing air quality were both mediating pathways affecting GS exposure and respiratory health, with physical activity being the most critical mediating variable, accounting for 43.06 % and 51.02 % of the total indirect effects, respectively. And variables such as age, BMI, and gender do not affect the mechanism. The respiratory health-promoting benefits of performing short-term exposure in urban green spaces had a lagged effect of at least 4 hours. The results of this study will help environmental epidemiologists to elucidate the pathways and mechanisms by which the green space system affects respiratory health and provide evidence for local governments to implement efficient and respiratory-healthy green space planning and design.

IntroductionMental disorders among young adults are a major health challenge. Mindfulness-based stress reduction (MBSR) has in previous research shown positive effects on mental health. However, research evaluating MBSR for young adults with mental disorders is insufficient and qualitative research exploring experiences of the programme is scarce. The aim of this study was to explore experiences of MBSR as a supplementary treatment in psychiatric outpatient care among young adults with moderate to severe mental disorders, from a short- and long-term perspective. MethodEleven young adults (aged 18–27 years) who had participated in an MBSR programme were interviewed approximately three months or two years later. The analytic method was Grounded Theory. ResultsThe analysis resulted in a theoretical model including one core category and five categories. The model illustrated a learning process, explaining the participants’ short- and long-term experiences of learning to pay attention to the body, regulate emotions, a change of attitude towards oneself, and still using skills two years after the programme. DiscussionThe MBSR programme was experienced as a learning process which improved the longstanding ability to cope with emotional stress in daily life. Tailoring MBSR to individual needs may further enhance its effectiveness. ConclusionThe experienced short- and long-term health-promotion benefits of an MBSR programme among young adults with mental disorders support its implementation in psychiatric and primary health care. Future research should investigate how to optimise implementation and tailor to individual needs.

Most of the phytochemical groups were present in the leaves, however majority of the tested compounds had consistent presence throughout the plants in all treatments. The underground stems possessed a greater total phenolic, tannin and proanthocyanidin contents than the leaves and roots under elevated CO2 and temperatures. The leaves had a comparatively better antioxidant activity from the treatment than control. Overall, there was consistency in the antibacterial activity in both control and experimental conditions. The tannins and phenolics had greater concentrations throughout the plants under elevated conditions overall, which could indicate their leading role in plant defence and the improvement and maintenance of the medicinal activity of B. natalensis. The responses of the plant parts of B. natalensis under elevated CO2 and temperatures provides newfound insights on the physiological roles plant organs play on the overall productivity and medicinal activity of the species.

Psoralidin: emerging biological activities of therapeutic benefits and its potential utility in cervical cancer

Cervical cancer (CaCx) is the fourth most prevalent cancer in women contributing to 341,831 annual deaths globally in 2020. Owing to its high mortality rate, the identification of novel inhibitors preventing CaCx progression is of utmost importance. Recent studies have emphasized the use of phytochemicals for cancer prevention due to their low toxicity. Psoralidin, a bioactive compound extracted from the seeds of the medicinal plant Psoralea corylifolia, showcases the potential for promoting health benefits. A range of studies showing anti-inflammatory, anti-oxidant, estrogenic, neuroprotective, anti-diabetic, anti-depressant, antimicrobial, and anti-tumor activities substantiate its promising biological effects. The anti-tumor potential of psoralidin has been well-documented. Its capacity to effectively target cancer stem cells (CSCs) in general adds to its therapeutic potential. Psoralidin carries out its anti-cancer activity by inducing oxidative stress, autophagy, and apoptosis. This unique characteristic suggests its potential to be used as an adjunct molecule in combination with existing treatment to enhance the efficacy of chemo/radiotherapy for treating CaCx. However, low bioavailability and intestinal efflux limit the use of psoralidin in clinical applications. Therefore, further investigation is needed in area of drug delivery and mechanism of action to fully harness the beneficial effects of psoralidin. The present study examines the current understanding of the molecular properties of this coumestan, as well as its various molecular targets with a particular emphasis on its anti-cancer activity. The study will help in designing effective and novel therapeutic interventions for targeting signaling pathways and other regulators involved in mediating CaCx progression, which will eventually help in effective management of CaCx.

Geraniol intake improves age-related malnutrition in mice.

Geraniol is an acyclic monoterpenoid that is abundant in many plants, including rose, lemongrass, and lavender. As geraniol has various beneficial functions, rose oil rich in geraniol is not only used for aromatherapy but also as a supplement to promote health benefits. However, the beneficial effects of geraniol on age-related pathologies are unknown. In this study, we aimed to clarify the effects of geraniol intake on age-related pathologies. We orally administered geraniol to aged mice (age: 24-29 months) five times a week for 4 weeks and sampled their blood and various organs. We investigated age-related changes in the blood and organ samples. Furthermore, we treated HepG2 cells with geraniol and examined the expression level of the ALB gene and the amount of secreted albumin in vitro. Geraniol significantly increased blood albumin, total cholesterol, and red blood cell counts, indicating an improvement in nutritional markers in aged mice. Geraniol also transcriptionally increased the Alb gene expression in the liver of aged mice. Furthermore, treatment with geraniol significantly upregulated the ALB gene expression and the secretion of albumin in the conditioned medium of HepG2 cells. Geraniol increases serum albumin levels at the transcriptional level. Geraniol intake can be an effective strategy for age-related malnutrition. Geriatr Gerontol Int 2024; 24: 1233-1240.
