The Impact

Schistosomiasis remains one of the most important neglected tropical diseases in the world. It mainly affects developing countries, where it often coexists with malnutrition. Despite this, few studies have investigated the relationship between schistosomiasis and malnutrition. Herein, we evaluate the impact of malnutrition on experimental S. mansoni infection. Mice were divided into 5 groups: Control (Ctrl) diet (14% protein and 10% lipids), low-protein 3% (LP 3%), low-protein 8% (LP 8%), low-fat 2.5% (LF 2.5%), and low-fat 5% (LF 5%). Mice were fed with their respective diets and were infected when a difference of approximately 20% in the body weight between mice from any experimental group and mice from the control group was achieved. Nutritional, parasitological, and immunological parameters were assessed either just before infection and/or approximately 50 days later before mice were perfused. Our results showed that the 3% low-protein diet was the only one capable of establishing malnutrition in mice. Mice fed with this diet showed: (i) significant reduction in body weight and serum albumin levels before infection, (ii) decreased levels of all biochemical parameters evaluated before perfusion, (iii) decreased numbers of schistosome eggs trapped in intestines and impaired parasite fecundity, (iv) a delay in the granuloma development with a smaller granuloma area, and (v) reduced levels of IL-4 and IFN-γ in the liver. Our findings demonstrate that low protein supply leads to malnutrition in mice and impacts the cytokine milieu in the liver and granuloma formation. Additionally, the establishment of our murine malnutrition model will enable future studies aiming to better understand the complex relationships between nutrition, immune responses, and infection outcome.

Poultry farming holds a special place in ensuring the products that the consumers demand, it provides the population with essential food products,such as eggs and meat,that contain vital micro and macronutrients, proteins, lipids, and vitamins. Therefore, the issues of rational, economically feasible feeding of meat poultry, namely broiler chickens, are an urgent task. It is also essential to find effective methods of their application in order to correct the natural resistance and immune and biological reactivity of birds. The purpose of this research is to study the effect of the biological stimulant-Nucleostim on the growth and development of chickens, hematological, and immunological parameters of the blood of birds.This Biostimulant is a purified bovine spleen extract containing at least 1 mg / ml of low molecular weight peptides (nucleotides and nucleosides) formed as a result of autolysis, using dry whey and diatomite as fillers. Onthe application ofNucleostim, the gain in live weight of chickens was increased by 9.7%. At the end of the experiment, the livability of the chicks of the experimental group treated with Nucleostimcame up to 88%, compared with the 72% of the control group. The use of biostimulant had a stimulating effect on the liver of chickens confirmed by the research results presented in the article, as well as contributed to the development of the thymus in the setting of general dystrophy. Thus, it improved chicklivability and increased body weight gain. The biological stimulant-Nucleostim as an adaptogenic, anabolic, and immunostimulatory agent is promising for finding new drugs that improve the health and productivity of poultry.

The Impact

Individuals with higher body weight are at a greater risk of having negative body image (Friedman & Brownell, 1995). Yet current body image interventions, such as Cognitive Behavioural Therapy (CBT), are largely tested with individuals with normal weight or individuals with eating disorders. Furthermore, cognitive restructuring, one of the key components of CBT for body image (Alleva et al., 2015), relies on the assumption that negative cognitions or appraisals regarding the body are unbalanced or distorted in some way. However, people with higher body weight are 50% more likely to experience major discrimination based on their weight status and thus may possess some “evidence” from lived experience of weight bias that would lend support to their negative body-related thoughts (Puhl & Brownell, 2001; 2006). The use of compassion-focused approaches might be particularly helpful in overcoming these obstacles. Self-compassion refers to the capacity for mindfully reflecting on one’s own perceived flaws, mistakes, or wrongdoings with kindness and with an appreciation for the inherent imperfection in everyone (Neff, 2013). The present study tested the impact of various thinking strategies for managing negative body image in women with higher body weight after getting on the scale, a commonly distressing body image trigger (Ogden & Evans, 1996). Participants (N = 79) were recruited from the community and screened for moderate body dissatisfaction. They were randomly assigned to receive a single training session in cognitive restructuring (CR), self-compassion (SC), or distraction (Control) strategies after being weighed. Participants in all three of the groups reported improvements in body dissatisfaction and negative affect immediately following the training. Relative to those in the Control group, those participants who received training in CR or SC strategies reported greater improvements in body image, body image flexibility, self-compassion, and cognitive distortions one week after the training. These findings suggest that CR and SC strategies may be helpful in improving the distress associated with being weighed among women with higher body weight. The results may have broader implications for the development of psychosocial interventions focused on improving body image among these individuals.

Introduction. Th e actual problem of modern occupational health is the study of the role of exogenous and endogenous factors in the development of occupational pathology of the bronchopulmonary system. То identify groups at increased risk of developing a dusty pathology of the bronchopulmonary system, it is necessary to conduct a comprehensive study of clinical and genetic factors, as well as to determine the most signifi cant diagnostic markers of the development of this pathology.The aim of the study was to study the genetic status of a set of biochemical and molecular genetic markers, as well as biochemical parameters of blood and respiratory function in coal industry workers with chronic dust bronchitis and persons of the control group.Materials and methods. 115 workers of coal mines from the South of Kuzbass aged from 39 to 58 years were examined in the Clinic of the Institute. Among them — 71 people with a previously established diagnosis of chronic dust bronchitis (the main group) and 44 people of the control group of persons working in the same sanitary conditions, but not having this pathology. A complex of clinical, biochemical and genetic methods of research was used in the study, and functional parameters of the bronchopulmonary system were evaluated. Statistical processing of the results was carried out using IBM SPSS Statistics 22 soft ware. Results. Statistically signifi cant diff erences between biochemical (increase in the concentration of ceruloplasmin and α–1antitrypsin) and immunological parameters (increase in the total number of leukocytes and ESR, increase in the concentration of IgG) in miners with chronic dust bronchitis and coal industry workers without this pathology were revealed. The dependence of the functional changes of the respiratory system with the development of professional pathology is determined. Th e persons of the main group showed a statistically signifi cant decrease in functional parameters (forced exhalation per second and lung capacity), increased respiratory failure. A predisposition to the development of dust bronchitis in the owners of the HP 1–1 genotype and resistance to the formation of this pathology in persons with the HP 2–2 genotype were found. Th e study of GSTT 1 deletion polymorphism revealed that carriers of the GSTT 1 «+» variant are most susceptible to the development of chronic dust bronchitis, and owners of the GSTT 1 variant are» resistant to its formation. Th ere was a positive аssociation with the development of dust bronchitis of the holders of the MM phenotype (MN).Conclusions. When working in similar conditions, some workers have a deviation of biochemical and immunological parameters fr om the norm, as well as a violation of the respiratory system, while others have no changes. Th e response of the body to the impact of certain external adverse factors may be due to genetic predisposition or resistance to the development of the disease.

AbstractCurrent nutritional recommendations are focused on energy, fat, carbohydrate, protein and vitamins. Less attention has been paid to the nutritional demand of one-carbon units for nucleotide and methionine synthesis. Here we investigate the impact of sodium formate supplementation as a nutritional intervention to increase the dietary intake of one-carbon units. A cohort of six female and six male mice received 125 mM sodium formate in the drinking water for three months. A control group of another six female and six male mice was also followed up for the same period of time. Tail vein blood samples were collected once a month and profiled with a haematology Analyser. At the end of the study blood and tissues were collected for metabolomics analysis and immune cell sorting. Formate supplementation has no significant physiological effect on male mice. Formate supplementation has no significant effect on the immune cell counts during the intervention or at the end of the study in either gender. In female mice however, the body weight and spleen wet-weight were significantly increased by formate supplementation, while the blood plasma levels of amino acids were decreased. Formate supplementation also increased the frequency of probiotic bacteria in the stools of female mice. We conclude that formate supplementation induces physiological changes in female mice.

Formate supplementation had no significant effect on the immune cell counts during the intervention or at the end of the study in either gender. In female mice, however, the body weight and spleen wet weight were significantly increased by formate supplementation, while the blood plasma levels of amino acids were decreased. Formate supplementation also increased the frequency of bifidobacteria, a probiotic bacterium, in the stools of female mice. We conclude that formate supplementation induces physiological changes in a gender-specific manner.

Previously, we have found that the addition of L-ascorbic acid to chitosan enhanced the reduction in body weight gain in guinea pigs fed a high-fat diet. We hypothesized that the addition of L-ascorbic acid to chitosan would accelerate the reduction of body weight in humans, similar to the animal model. Overweight subjects administered chitosan with or without L-ascorbic acid for 8 weeks, were assigned to three groups: Control group (N = 26, placebo, vehicle only), Chito group (N = 27, 3 g/day chitosan), and Chito-vita group (N = 27, 3 g/day chitosan plus 2 g/day L-ascorbic acid). The body weights and body mass index (BMI) of the Chito and Chito-vita groups decreased significantly (p < 0.05) compared to the Control group. The BMI of the Chito-vita group decreased significantly compared to the Chito group (Chito: -1.0 kg/m2 vs. Chito-vita: -1.6 kg/m2, p < 0.05). The results showed that the chitosan enhanced reduction of body weight and BMI was accentuated by the addition of L-ascorbic acid. The fat mass, percentage body fat, body circumference, and skinfold thickness in the Chito and Chito-vita groups decreased more than the Control group; however, these parameters were not significantly different between the three groups. Chitosan combined with L-ascorbic acid may be useful for controlling body weight.

Summary. The disbalanced feeding and the uneven distribution of micro- and macroelements in the environment leads to a trace element, in particular hypomelanosis. To accelerate the growth and preservation of young farm animals include in the diet of various biological additives and drugs, which include selenium. For stimulation of weight gain in the livestock industry, as well as for the prevention and treatment of pathological processes in addition to micro - and macrouse amino acids, primarily methionine. The aim of this work was to study the influence of composition of DAFS-25+Polizon on morpho-biochemical parameters of blood and functional state of the liver in fattening bulls of black-motley breed in the conditions of the Republic of Bashkortostan. Experiments using were conducted on bull-calves of black-motley breed of the properties in the properties age from 6 to 15 months. The first experimental group during the experiment was additionally given the composition of DAFS-25+Polizon at a dose of 2 mg/kg, the animals of the control group received a standard diet. To assess the impact of the composition DAFS-25+Polizon on metabolism cattle studied morphological and biochemical indicators of blood and conducted histological examination of the liver. It is established that the use of the composition of DAFS-25+Polizon at a dose of 2 mg/kg increases the number of erythrocytes and hemoglobin in the experimental group and reduces the amount of white blood cells. The serum content of total protein, phosphorus and calcium increases in the group of experimental animals. Microscopic examination of the liver revealed no changes in the structure of the organ and hepatocytes in the experimental group, whereas in the control group hemodynamic disorders and dystrophic changes in liver cells were observed. Thus, the use of the composition DAFS-25+Polizon at a dose of 2 mg/kg of live weight in fattening bulls black-and-white breed contributes to the increase of redox processes in the body, stimulation of metabolism, prevent the development of liver disorders of cellular mechanisms of metabolism, optimizes the structure of the liver, which generally provides higher productivity.

Effect Of Feeding

Background : Female menstrual changes in hormone concentration influence appetite and eating behavior. As well, eating pattern has some influences on menstrual hormonal status. Feeding date palm fruit has been found in our previous report to affect menstrual hormones and some menstrual parameters. Objective: The aim of this research is to study the effect of feeding dates on energy, macronutrient, and fiber intakes, body weight, and body fat%. Additionally, this study aims to find any correlation between menstrual hormone concentration and the above-mentioned parameters. Methods: A convenient sample (n=37) of not-sexually active females aged 20-30 were divided into two groups; one group (dates group) was fed 7 dates and the other served as a control group. The participants of the control group were exposed to the same experimental conditions except for eating dates. Throughout the feeding trial, the volunteers filled a 3-day food record; one menses day and two non-menses days. Results: There was a significant effect of the menstrual status-feeding duration interaction in terms of protein and fat intakes. Additionally, menstrual status, as well as feeding duration, affected energy and macronutrient intakes significantly. Furthermore, feeding duration affected fiber intake significantly. Despite the above-mentioned differences in energy and macronutrient intakes, these effects didn’t affect the body weight and body mass index of the study participants, neither their body fat%. Moreover, we have found significant correlations between nutrient intakes and menstrual hormone concentration. Conclusion : Feeding dates affected energy, macronutrient, and fiber intakes significantly. These effects were related to the changes in menstrual hormone concentration.

This study was initiated on 24 prepubertal Holstein x Kankrej crossbred heifers of nearly identical age (7-9 months) and body weight (130-140 kg) at University farm to evaluate the effect of high plane of nutrition on blood biochemical and minerals profile and the age at puberty. Twelve heifers were managed under routine farm feeding (control) and the rest 12 under ideal optimum feeding regime (treatment) that included extra 1 kg concentrate, 30 g min mix and ad-lib dry fodder. The body weight and ovarian ultrasonography together with blood sampling was carried out at monthly interval from 10 to 18 months of age to study the ovarian dynamics and blood biochemical changes. High plane of nutrition to growing heifers was beneficial in reducing the age of onset of puberty (by 2-3 months) compared to routine farm fed group. The mean plasma total protein and cholesterol concentrations showed a rising trend with significant variations from 10 to 16 months of age, where it got mostly stabilized indicating adult profile. The activity of enzymes GOT and GPT also rose gradually and significantly from 10 months till 14-15 months of age, and thereafter it remained more or less static till 18 months of age. The levels of both these enzymes were higher, with lower protein and cholesterol, in control than the treatment group from 15-16 months of age onwards. The mean plasma levels of both calcium and phosphorus increased gradually and significantly with advancing age till 16-17 months of age, with little higher values in supplemented than a control group. The plasma levels of zinc, iron, copper, and cobalt also showed rising trend with significant differences between 10th and 12th-14th months of age, and from 15th to 18th months of age the levels were statistically the same in all the groups with slightly higher values in the treatment group.

AbstractCombinations of fructose- and fat-rich diets in experimental animals can model the human metabolic syndrome (MS). In rats, the increase in blood pressure (BP) after diet manipulation is sex related and highly dependent on testosterone secretion. However, the extent of the impact of diet on rodent hypophysial-testicular axis remains undefined. In the present study, rats drinking a 10% fructose solution or fed a high-fat (35%) diet for 10 weeks had higher plasma levels of luteinizing hormone (LH) and lower plasma levels of testosterone, without significant changes in circulating follicle-stimulating hormone or the weight of most reproductive organs. Diet manipulation brought about a significant increase in body weight, systolic BP, area under the curve (AUC) of glycemia after an intraperitoneal glucose tolerance test (IPGTT), and plasma low-density lipoprotein cholesterol, cholesterol, triglycerides, and uric acid levels. The concomitant administration of melatonin (25 μg/mL of drinking water) normalized the abnormally high LH levels but did not affect the inhibited testosterone secretion found in fructose- or high-fat-fed rats. Rather, melatonin per se inhibited testosterone secretion. Melatonin significantly blunted the body weight and systolic BP increase, the increase in the AUC of glycemia after an IPGTT, and the changes in circulating lipid profile and uric acid found in both MS models. The results are compatible with a primary inhibition of testicular function in diet-induced MS in rats and with the partial effectiveness of melatonin to counteract the metabolic but not the testicular sequelae of rodent MS.
