Evaluation of the agri-food supply chain risks: the circular economy context

PurposeCircular supply chains (CSC) are particularly important for the agri-food sector, which faces strict requirements generated by increased food consumption as a consequence of world population growth, changes in lifestyle, development of consumer society and increasing health awareness. Recent disruptive factors have placed the vulnerability of agri-food supply chains in the spotlight. Therefore, the purpose of this paper was to identify the most manageable groups of risks in order to ensure the smooth operation of agri-food circular supply chains.Design/methodology/approachSeven main risk groups were evaluated in relation to nine criteria. To solve this multi-criteria decision making (MCDM) problem, a novel MCDM model, which integrates the best-worst method (BWM) and the COmprehensive distance-Based RAnking (COBRA) method in a grey environment, was developed.FindingsThree risks were singled out, namely, product features risks, logistics risks and managerial risks. The obtained risks are those whose management would create the most positive effects for the stakeholders and help them achieve their primary goals regarding the circularity of agri-food supply chains.Originality/valueThis study investigates the main characteristics of the CSC in the agri-food sector, identifies, simultaneously explores and ranks all main risk groups associated with them and expands the possibilities for solving these kinds of problems by developing a novel MCDM model. It also identifies the most significant risks, both for individual stakeholders and for all stakeholder groups together.

Effect of integrated sustainable land management technologies on households’ food security in the North Gojjam sub-basin, Blue Nile River

Integrated Sustainable Land Management (ISLM) is progressively viewed as a key strategy to boost food security in Ethiopia and feed its growing population. By understanding this logical ground, this paper examines the effect of ISLM technologies adoption on household food security. The study relies on cross-sectional household-level data collected from 414 randomly selected household heads across three districts to analyze this issue. An Endogenous Switching Regression (ESR) model coupled with the Full Information Maximum Likelihood (FIML) technique was applied to analyze the required data. The finding shows that the adoption of ISLM technologies has significantly increased food security. It specifically increases food consumption expenditure in households by ETB (national currency in Ethiopia; as of August 2021, 1 ETB is equal to approximately USD $0.02) 38.3 (27%) when compared to households that do not adopt groups. Similarly, it increases the adopter households’ dietary diversity by 14.5%. Furthermore, it plays a significant role in reducing the food gap period by one and a half months per year and the food insecurity access scale by 46% points in the north Gojjam sub-basin for those who adopted versus those who did not adopt. The policy implication is that the adoption of ISLM technologies can improve rural household food security and may be used as a means of reducing rural poverty. As a result, the adoption of ISLM technologies should have been promoted in the study area and elsewhere by inspiring land users by accessing external agricultural inputs at the right time and place to increase small-scale land productivity.

Theory of consumer behavior in the restaurant business

Over the past two years, the food industry has faced many challenges. The situation around the world was repeated as the pandemic led to the cessation of the restaurant business and the introduction of quarantine restrictions. Although most restaurants have reopened and customers are returning, the industry is still facing challenges.As the pandemic progressed, consumers learned to cook more meals at home, leading to increased food consumption and a refusal to visit restaurants. Consumer behavior is a complex topic, it involves many different factors and aspects that influence each other and are interrelated, but these differences are often discussed separately. The restaurant business should provide quality services, a good brand image and improve the quality of food, in order to ensure customer loyalty.

Complementary lateral hypothalamic populations resist hunger pressure to balance nutritional and social needs

Animals continuously weigh hunger and thirst against competing needs, such as social contact and mating, according to state and opportunity. Yet neuronal mechanisms of sensing and ranking nutritional needs remain poorly understood. Here, combining calcium imaging in freely behaving mice, optogenetics, and chemogenetics, we show that two neuronal populations of the lateral hypothalamus (LH) guide increasingly hungry animals through behavioral choices between nutritional and social rewards. While increased food consumption was marked by increasing inhibition of a leptin receptor-expressing (LepRLH) subpopulation at a fast timescale, LepRLH neurons limited feeding or drinking and promoted social interaction despite hunger or thirst. Conversely, neurotensin-expressing LH neurons preferentially encoded water despite hunger pressure and promoted water seeking, while relegating social needs. Thus, hunger and thirst gate both LH populations in a complementary manner to enable the flexible fulfillment of multiple essential needs.

The impact of COVID-19 quarantine on lifestyle indicators in the United Arab Emirates.

COVID-19 is a virus that has spread rapidly and brought economic and social crises all around the world. The current study aimed to investigate the impact of COVID-19 quarantine on dietary habits, physical activity, food purchasing, smoking, and sleeping patterns in the United Arab Emirates. A cross-sectional study was conducted using an online questionnaire between November 1st, 2020 and the end of January 2021. Citizens and residents of the UAE aged ≥ 18 years old were asked to complete an anonymous electronic questionnaire created via Google Forms and distributed on various platforms, such as WhatsApp, Twitter, and email. A total of 1682 subjects participated in the study. The results included that during the COVID-19 lockdown, more participants (44.4%) reported an increase in weight. This gain seems to be linked to increased food consumption [(Adjusted Odd Ratio) AOR = 1.68, 95% (Confidence Interval) CI = 1.12, 2.54, p = 0.022], decreased physical activity (AOR = 2.25, 95% CI = 1.58, 3.21, p < 0.001), and increased smoking (AOR = 1.90, 95% CI = 1.04, 3.50, p = 0.038). The groups that were most likely to gain weight included those who consumed more cereals (AOR = 1.67, 95% CI = 1.08, 2.57, p = 0.011), had an increased desire for sweets (AOR = 2.19, 95% CI = 1.50, 3.19, p < 0.001), and an increased desire for food (hunger) (AOR = 2.19, 95% CI = 1.53, 3.14, p < 0.001). In contrast, those who exercised more were more likely to lose weight (AOR = 0.61, 95% CI = 0.44, 0.86, p < 0.001) as well as those who slept over 9 h a day (AOR = 1.90, 95% CI = 0.45, 0.88, p = 0.006). Overall, it is essential to promote healthy habits and methods of healthy diet maintenance during stressful and unusual times when people might find it difficult to put effort into their health.

Sex-specificity of the C. elegans metabolome

Recent studies of animal metabolism have revealed large numbers of novel metabolites that are involved in all aspects of organismal biology, but it is unclear to what extent metabolomes differ between sexes. Here, using untargeted comparative metabolomics for the analysis of wildtype animals and sex determination mutants, we show that C. elegans hermaphrodites and males exhibit pervasive metabolomic differences. Several hundred small molecules are produced exclusively or in much larger amounts in one sex, including a host of previously unreported metabolites that incorporate building blocks from nucleoside, carbohydrate, lipid, and amino acid metabolism. A subset of male-enriched metabolites is specifically associated with the presence of a male germline, whereas enrichment of other compounds requires a male soma. Further, we show that one of the male germline-dependent metabolites, an unusual dipeptide incorporating N,N-dimethyltryptophan, increases food consumption, reduces lifespan, and accelerates the last stage of larval development in hermaphrodites. Our results serve as a foundation for mechanistic studies of how the genetic sex of soma and germline shape the C. elegans metabolome and provide a blueprint for the discovery of sex-dependent metabolites in other animals.

Effects of central FGF21 infusion on the glucose homeostasis in rats (brain–pancreas axis)

Introduction Glucose homeostasis is a physiological process mediated by a variety of hormones. Fibroblast growth factor (FGF) 21 is a protein expressed in the liver, adipose tissue, muscle and pancreas and exerts actions in multiple targets including adipose, liver, pancreas and hypothalamus. The aim of this study was to examine the possible involvement of FGF21 in pancreatic and central control of glucose by measuring reflective changes in the release of insulin and glucagon. Methods Thirty adult male Wistar Albino rats were divided; Control, PD + aCSF, PD + FGF21 groups (n = 10). Effects of intracerebroventricular (icv) FGF21 administration to pancreatic denervated (PD) rats. Agouti-related protein (AgRP), Pro-opiomelanocortin (POMC) levels and blood glucose homeostasis were investigated. Results Administration of FGF21 to 3rd ventricle increased food consumption but body weight didn’t change significantly. AgRP level increased, pancreatic insulin levels increased, and glucagon level decreased. Conclusion Central FGF21 administration is effective in regulating blood glucose homeostasis by increasing the amount and efficiency of insulin and changing glucose use.

Changing Food Consumption Pattern and Influencing Factors in Bangladesh.

Food consumption is an important bridge between human beings and the natural ecosystem. The change in food consumption quantity and quality can reflect the relationship between them. This study aims to explore food consumption characteristics and the drivers of food consumption patterns in Bangladesh with a fragile ecology and polluted environment. This research selected food consumption in Bangladesh as the object, food consumption data were obtained from the Food and Agriculture Organization of the United Nations, and the data of influencing factors mainly were acquired from the World Bank. The following results were conducted: The total and per capita food consumption showed increase as a whole, but per capita food consumption experienced decline in the middle of the research period. Food consumption patterns were divided into three types: the first type of cereal-sugar-aquatic with low food consumption quantity and few kinds of food from 1961 to 1971, the second type of cereal-sugar-oil-aquatic with increasing food consumption quantity and food kinds from 1972 to 1997, and the third type of cereal-aquatic-tuber-sugar-fruit-vegetable-meat with increasing food consumption quantity and more various kinds of food from 1998 to 2020. The characteristics of food consumption in different periods were influenced by a series of factors. The influence of economic factors was higher than other factors, relatively. According to this study, the characteristics of food consumption patterns and the relationship between food consumption and influencing factors can provide a scientific reference for the adjustment policy makers taking local food demand and natural resources conservation into consideration to achieve a sustainable development.

Increasing Food Consumption With an Antecedent and Reinforcement-Based Treatment Generalized Via Telehealth

We report a case with a 7-year-old girl with autism spectrum disorder and anxiety disorder who had severe restrictive eating leading to various medical concerns raised by her pediatrician. Following medical consultation and a descriptive functional assessment, a therapist implemented behavioral intervention consisting of a visual cue, choice, and differential reinforcement of alternative behaviors. The intervention was focused on both in-home meals and telehealth consultation during mealtimes, as the COVID-19 pandemic necessitated moving to remote consultation for continued treatment. The success of this study has long-standing implications for the benefits of positive feeding interventions and telehealth as well as parental training strategies.

Impact of Natural Disaster on Health of Children: Empirical Evidence from Nepal’s Earthquake

This study estimates the impact of the 2015 Nepal earthquake on the health of children: weight, height, and body mass index (BMI). It uses two rounds of data related to Nepal Demographic Health Surveys (NDHS) before and after the earthquake, i.e., in 2011 and 2016. The study combines child-related information and household-level data from NDHS with the earthquake data available at the district level to identify the impact of earthquakes on children’s health. By focusing on children between 0 to 5 years of age and using the difference-in- difference framework as an identification strategy, results show that the BMI increased for children living in affected areas. This increase in BMI is primarily driven by an increase in their weight. The study further shows that the BMI of children increases in earthquake-affected areas because of the increased food consumption. The study underscores the importance of being selective in the type of food-aid distributed as well as changing the consumption behavior of children during the post-disaster periods.

Nutritional Behaviour of Adolescents and the Impact of Covid-19 on A Diet in Saudi Arabia

Background In recent decades, changes in food consumption among adolescents in Arabic speaking countries, including The Kingdom of Saudi Arabia (KSA), has resulted in increased burden of overweight and obesity. COVID-19 related restrictions have further impacted lifestyle and diet among adolescents in KSA. Aim The present study aimed to assess the knowledge, attitude, behaviour and dietary patterns of adolescents and the impact of the COVID-19 pandemic related restrictions on these behaviours. Methods A cross-sectional study was conducted in six intermediate schools among 1500 adolescents (11-15 years) via an anonymous online survey. The Chi Square test was used to compare gender stratified nutritional knowledge, attitude and behaviour of adolescents and the impact of COVID-19 related restrictions. To determine the factors associated with nutritional change during COVID-19 lockdown, logistic regression was employed using the categorisation of nutritional change during COVID-19 restrictions versus no change in univariate and multivariate analyses. Results A good level of nutrition-related knowledge and attitude was demonstrated both by female and male students, with 66% and 57% of participants scoring above the median of the total possible knowledge and attitude score, respectively. After adjusting for all variables, higher nutrition knowledge score predicted students to be less likely to report increased food consumption during COVID-19 restrictions, whereas students with higher nutrition attitude scores and with a higher risk of increased food consumption were more likely to increase food consumption during COVID-19 restrictions. Conclusions Unhealthy dietary habits among Saudi adolescents are of paramount public health concern and the COVID-19 restriction period exacerbated the pre-pandemic nutrition-related unhealthy behaviours. Therefore, school-based interventions aiming to promote healthy lifestyles and the wellbeing of Saudi adolescents and use of qualitative recall dietary diary is also crucial to develop programs that prevent unhealthy lifestyles in adolescents in Saudi Arabia.

Intranasal ondansetron microemulsion counteracting the adverse effects of cisplatin: animal study

BackgroundCisplatin is considered one of the most effective and commonly used chemotherapeutic drugs, but despite its high therapeutic effectiveness, most patients treated with cisplatin suffer from nausea and vomiting, neurotoxic side effects, and cerebral psychiatric disorders such as depression. Therefore, the aim of the current work was to explore whether a selective 5-HT3 receptor antagonist (Ondansetron) administered via the oral route or intranasally in microemulsion form would alleviate cisplatin’s adverse effects.MethodsThe selected ondansetron microemulsion was characterized in vitro for particle size, polydispersity, zeta potential, morphology, and nasal permeation, and in vivo in terms of anti-emetic and antidepressant activity, with the assessment of biochemical markers in brain homogenates.ResultsResults revealed that both orally administered ondansetron and intranasally administered microemulsion were able to counteract the pica effect by increasing food consumption, water intake, and decreasing kaolin intake. They were also able to increase BDNF, normalize IL-6, increase serotonin, and normalize NOx, MDA, GSSH/GSH as well as 8OHdG levels in rats’ brain homogenates. The intranasal ondansetron microemulsion displayed superiority compared to oral conventional ondansetron in terms of increasing food intake, reduction of stomach content, and normalization of serotonin turnover.ConclusionOndansetron microemulsion can be administered by an alternative route of administration (intranasal) rather than oral, for patients on cisplatin chemotherapy.Graphical

Disconnect between sympathetically-induced hunger suppression and consumption among highly restrained eaters following stress

Despite emphasis on findings suggesting restrained eaters increase food consumption under stress, unrestrained eaters' reduction in intake is more robust. Early proposals asserted unrestrained eaters significantly reduced intake after certain threats due to the hunger-inhibiting effects of autonomic influences, presuming unrestrained eaters are more responsive to these effects and restrained eaters rely less on physiological cues for eating. However, scant empirical evidence has substantiated these claims. This study examined whether a sequence exists whereby stress elicits autonomic activation, autonomic activation impacts hunger, and hunger then impacts eating, with dietary restraint altering the hunger-intake link. It was hypothesized that sympathetic nervous system activation would be greatest when ongoing safety from stress was uncertain, sympathetic activation would be linked to reduced hunger, and lower hunger would be associated with attenuated intake. Restraint, conceptualized via Hagan et al.’s (2017) latent restraint factors, was hypothesized to reduce the association between hunger and intake. Female participants (n = 147) were randomized to a stress + certain safety, stress + uncertain safety, or control condition. Sympathetic nervous system activity was recorded prior to a bogus taste test, which quantified ad libitum consumption of highly-palatable snack foods post-stress. Only the stress + uncertain safety condition exhibited greater sympathetic nervous system activity than the control condition. A significant index of moderated serial mediation emerged for Preoccupation with Dieting and Weight-Focused Restraint in the stress + uncertain safety condition. Though sympathetic activation decreased hunger similarly regardless of dietary restraint, only less restrained individuals significantly decreased intake. More restrained individuals ate more despite experiencing lower hunger. The disconnect between hunger and intake in more restrained eaters suggests that focus on enhancing attunement to hunger may yield greater benefit than enhancing restraint. 281 words.

Research on the Impact of Farmland Transfer on Rural Household Consumption: Evidence from Yunnan Province, China

By constructing the analytical framework of “farmland transfer—farmland function—income structure—rural household consumption”, based on the sample data of 537 rural households in 50 villages in Yunnan Province of China, this paper uses the OLS model to explore the impact of farmland transfer on rural household consumption and uses an intermediary effect model to further explore its internal transmission mechanism. The research finds that: (1) Farmland transfer (farmland transfer-out or farmland transfer-in) can stimulate rural household consumption. (2) The coefficient of farmland transfer-out to non-food consumption is 0.118, which is greater than its coefficient of food consumption of 0.016; the rural households of farmland transfer-out are more willing to increase non-food consumption expenditure, which is conducive to the optimization of their consumption structure. (3) The coefficient of farmland transfer-in to food consumption is 0.028, which is greater than its coefficient to non-food consumption of 0.009; the rural households of farmland transfer-in are more willing to increase food consumption expenditure, which is not conducive to the optimization of their consumption structure. (4) Rural household consumption expenditure will show a downward trend with the increase in the age of the head of the rural household, and the consumption structure will also show a deterioration. (5) The more family assets rural households have, the stronger their consumption expenditure capacity, which is conducive to optimizing their consumption structure. (6) The results of the intermediary effect model show that farmland transfer affects rural households’ consumption and consumption structure by affecting rural households’ income under different livelihood modes. Accordingly, the paper puts forward some suggestions on establishing the benefit coordination mechanism of farmland transfer, improving the non-agricultural employment mechanism of the rural surplus labor force, raising the expected return on farmland investment, increasing the proportion of household income saved appropriately and strengthening the social security mechanism in order to further promote the orderly transfer of farmland, improve the consumption capacity and consumption level of rural households, expand rural domestic demand and promote rural consumption upgrading.

Acylated Ghrelin Receptor Agonist HM01 Decreases Lean Body and Muscle Mass, but Unacylated Ghrelin Protects against Redox-Dependent Sarcopenia.

Sarcopenia, the progressive loss of muscle mass and dysfunction, universally affects the elderly and is closely associated with frailty and reduced quality of life. Despite the inevitable consequences of sarcopenia and its relevance to healthspan, no pharmacological therapies are currently available. Ghrelin is a gut-released hormone that increases appetite and body weight upon acylation, which activates its receptor GHSR1a. Recent studies have demonstrated that acyl and unacylated ghrelin are protective against acute pathological conditions of skeletal muscle. We hypothesized that both acyl ghrelin receptor agonist (HM01) and unacylated ghrelin ameliorate muscle atrophy and contractile dysfunction in oxidative stress-induced sarcopenia. HM01, unacylated ghrelin, or saline was delivered via osmotic pump. HM01 increased food consumption transiently, while the body weight remained elevated. It also decreased lean body mass and muscle mass of wildtype and Sod1KO. In contrast, unacylated ghrelin ameliorated loss of muscle mass by 15-30% in Sod1KO mice without changes in food consumption or body weights. Contractile force was decreased by ~30% in Sod1KO mice, but unacylated ghrelin prevented the force deficit by ~80%. We identified downregulation of transcription factor FoxO3a and its downstream E3 ligase MuRF1 by unacylated ghrelin. Our data show a direct role of unacylated ghrelin in redox-dependent sarcopenia independent of changes of food consumption or body weight.

Beyond productivity, does the adoption of agricultural technologies improve food consumption and reduce poverty? Empirical evidence from Benin

ABSTRACT Beyond productivity, does the adoption of agricultural technologies improve food consumption and reduce poverty? To provide answers to this, the paper used data from the household survey on the Comprehensive Food Security and Vulnerability Analysis (CFSVA) carried out in 2017 in Benin. Five agricultural technologies were considered in this study. First, an extended ordered probit model was estimated to analyze the impact of technology choice sets on food consumption groups (poor, limit and acceptable). Second, an extended probit model is employed to assess the impact on poverty status. The results show that the adoption of multiple technologies increases food consumption and reduces poverty among agricultural households in Benin. Combinations of technologies that enhance both food consumption and poverty status are irrigation and herbicide, irrigation and chemical fertilizers and improved seed and chemical fertilizers. Therefore, policy interventions should help farming households gain access to these improved technologies to improve food security and reduce poverty.

A Retrospective Consecutive Controlled Case Series of Underspoon: A Modified-Bolus Placement to Address Behavior That Interfere With Swallowing.

Children diagnosed with pediatric feeding disorder (PFD) or avoidant/restrictive food intake disorder (ARFID) may present with comorbid oral-motor delays that often contribute to their failure to consume an adequate volume and/or variety of foods. Once the food enters the mouth, these children may exhibit additional problematic behavior such as expulsion and packing that further averts oral intake. Previous research has evaluated the impact of modified-bolus placement methods, including flipped spoon and NUK® brush, in comparison to upright spoon on expulsion and packing. Whether responses are due to performance or skill deficits, researchers hypothesize that modified-bolus placement may assist with reducing the response effort associated with swallowing. This retrospective consecutive controlled case series assessed the clinical application of an additional modified-bolus placement method, underspoon, to increase food consumption and decrease problematic behavior that interfere with mouth clean for children with PFD or ARFID.

A study on water intake and food consumption in animals treated with Thyroxine followed by Bauhinia Purpurea and Withania Somnifera - Original Research

Background: There has been a tremendous range of interest in drugs obtained from medicinal plants that are believed to be safer with significant efficacy in the treatment of thyroid disorders Objective: to observe the water intake and food consumption in animals treated with Thyroxine followed by Bauhinia Purpurea and Withania Somnifera. Materials and Methods: A total of 30 adult female Albino rats of Wistar Strain weighing 150-230 grams were utilized for the present study. The animals were maintained and the protocol was approved by the Institutional Animal Ethical Committee (No.878/ac/05/CPCSEA/23/11) from Raghavendra Institute of Pharmaceutical Education &amp; Research (RIPER), Anantapur, Andhra Pradesh. The animals were divided into 5 groups and each group consisted of 6 animals in our study Results: The mean water intake rate was significantly decreased (25.94+0.42) in the rats treated with thyroxine (0.5 mg/kg b.w) followed by Bauhinia purpurea (150mg) and Withania somnifera (1000mg) when compared control group was 29.44+0.27. The food consumption rate was significantly increased in the rats treated with Thyroxine(0.5 mg/kg b.w) 21.33+1.71 when compared to the control group in our study Conclusion: The animals treated with thyroxine alone showed increased food consumption compared with other experimental and control groups, whereas water intake was significantly higher in control animals than other experimental groups.

Preclinical comparison of antinociceptive effects between ibuprofen, diclofenac, naproxen, and acetaminophen on acid-stimulated body stretching and acid-depressed feeding behaviors in rats.

Pain is a major problem that burdens the health and economy of societies worldwide. Nonsteroidal anti-inflammatory drugs (NSAIDs) are over-the-counter medications that are widely indicated for mild to moderate pain conditions. Clinically, the selection of a medication among this class is mainly based according to both patient's and doctor's previous experiences. Herein, we studied differences in therapeutic efficacies among the most commonly prescribed NSAIDs and acetaminophen in inflammatory pain rat model. Body stretching and food consumption behaviors were assessed after intraperitoneal administration of lactic acid. Initially, different concentrations of lactic acid were evaluated in adult male rats in both behavioral models. Acid concentrations of 1.8 and 3.2% were selected to assess the effects of ibuprofen, diclofenac, naproxen, and acetaminophen in body stretching and feeding behaviors, respectively. In the feeding study, food restriction for 1-24 h prior to feeding studies was assessed at first, and 24 h was selected for further tests. Acetaminophen (100 mg/kg), diclofenac (10 mg/kg), ibuprofen (10-32 mg/kg), and naproxen (3.2-10 mg/kg) significantly decreased acid-stimulated body stretching. Likewise, acetaminophen (100 mg/kg), diclofenac (10 mg/kg), and ibuprofen (32 mg/kg) increased food consumption significantly after 3.2% lactic acid. There were no significant differences between different test drugs efficacies in both stretching and feeding behaviors. In conclusion, feeding behavior provides a good appraisal for pain and analgesic drugs in preclinical studies. There were comparable efficacies between all tested medications in both lactic acid-stimulated body stretching and -depressed feeding behaviors.

The effect of infection risk on female blood transcriptomics

Defenses against pathogens can take on many forms. For instance, behavioral avoidance of diseased conspecifics is widely documented. Interactions with these infectious conspecifics can also, however, lead to physiological changes in uninfected animals, an effect that is much less well understood. These changes in behavior and physiology are particularly important to study in a reproductive context, where they can impact reproductive decisions and offspring quality. Here, we studied how an acute (3 h) exposure to an immune-challenged male affected female blood transcriptomics and behavior. We predicted that females paired with immune-challenged males would reduce eating and drinking behaviors (as avoidance behaviors) and that their blood would show activation of immune and stress responses. We used female Japanese quail as a study system because they have been shown to respond to male traits, in terms of their own physiology and egg investment. Only two genes showed significant differential expression due to treatment, including an increase in the threonine dehydrogenase (TDH) transcript, an enzyme important for threonine breakdown. However, hundreds of genes in pathways related to activation of immune responses showed coordinated up-regulation in females exposed to immune-challenged males. Suppressed pathways revealed potential changes to metabolism and reduced responsiveness to glucocorticoids. Contrary to our prediction, we found that females paired with immune-challenged males increased food consumption. Water consumption was not changed by treatment. These findings suggest that even short exposure to diseased conspecifics can trigger both behavioral and physiological responses in healthy animals.
