194 Effects of combining plant and yeast extracts with essential oils or protected betaine on performance and health of weaned piglets

Abstract To raise piglets without antibiotics and high trace elements levels, favoring immune development and maturation is a potentially successful strategy, as long as over-stimulation of immune system does not harm animal performance. A trial was undertaken to evaluate response of piglet to varied blend of plant and yeast extracts selected for renowned effects on immune system. Weanling piglets (n = 400; 21 d of age), females and castrated males, were allocated to 4 dietary treatments across 80 pens: negative control (NC), blend of plant and yeast extracts for immune stimulation added to NC (B1), essential oils with anti-inflammatory properties added to B1 (B2), protected betaine added to B2 (B3). Pre-starter diets were fed from weaning to d 42, followed by starter diets offered until the end of the trial at d 69. On d 49, coughing and sneezing (CS) were counted per pen in both rooms, and individual fecal samples were taken from 20 piglets per diet, selected at weaning, to assay total peroxidase activity (TPO), a marker of gut inflammation. Statistical analyses were performed on pen data to analyze effects of treatment on piglet growth rate (average daily gain; ADG), feed intake (average daily feed intake; ADFI) and feed conversion ratio (FCR). The model included the effect of weaning weight, treatment, and interactions. Linear contrasts were used to compare B1 to NC, B2 to B1, and B3 to B2. A similar model was applied to individual fecal TPO measurements. Sneezing count frequency was analyzed with Chi² statistics and odd ratio (OR) were computed per treatment. Dietary treatment did not affect CS counts. Compared with NC, B1 reduced initial ADG and ADFI (from d 21 to 42) and increased initial FCR (P < 0.05). In the following period, ADG, ADFI and FCR improved with B1 (P < 0.05), resuming body weight (BW; final BW: 26.8, 26.8, 27.3 and 27.5, P > 0.20, for NC, B1, B2 and B3, respectively). Overall FCR slightly decreased (1.66 vs. 1.64, P < 0.05, for NC and B1 respectively). Compared with B1, B2 increased initial ADG and ADFI (ADG21-42: 0.244 vs. 0.258 kg, P < 0.05, for B1 and B2, respectively), and decreased FCR initial and overall (overall: 1,64 vs. 1.60, P < 0.05, for B1 and B2 respectively). B2 also minimized fecal TPO compared with other treatments (Uּּ•mL-1: 13.7 vs. 21.3 vs. 7.0 vs. 10.1, P < 0.001, for NC, B1, B2 and B3, respectively). B3 did not provide statistical benefit over B2. In this trial, immune stimulation decreased initial growth and reduced feed efficiency. Anti-inflammatory essential oils tempered consequences of gut inflammation and restored performance, while protected betaine did not provide additional benefit.

Exploring the link between hair elemental composition and oral and general health of children in Northern and Central Dagestan Russia

Relevance. This article presents data on the level of trace elements in hair and oral and general health among various age groups of children (from 2 to 17 years) in Northern and Central Dagestan. It also reports findings on the relationship between oral health indicators and the content of such macro- and microelements as Ca, Cu, Mg, Mn, Zn, As, Fe, F. Identifying concentrations of macro- and microelements in hair proves to be a promising diagnostic method and aids in creating personalized prevention programs.Objective. To investigate the correlation between the elemental composition in children's hair and their oral and general health conditions in the cities of Kizlyar and Makhachkala, situated in Northern and Central Dagestan, Russia.Materials and methods. Established methods and physicochemical techniques were utilized for oral health evaluations to determine the quality indicators of drinking water, levels of elemental composition in hair, and methods to assess the general health of children (questionnaires, analysis of medical records of children).Results. A correlation was established between the levels of specific chemical elements in hair, the dental hard tissues, and mixed saliva with the oral and general health complications observed in children. Water analysis in Makhachkala, central part of the Republic of Dagestan, revealed an unbalanced presence of essential chemical elements such as fluoride, iron, manganese, zinc, and sulfates. In 74–84% of the examined water samples, the fluoride content was below 0.5 mg/l, and only 13–25% were within the normal range. The levels of fluoride and iron in hair and mixed saliva indicate shifts in mineral metabolism in children's bodies. Fluoride is crucial for iron absorption, and its deficiency results in significantly decreased absorption rates. A substantial reduction in water fluoride levels, compared to standard values, correlates with high rates of dental caries and iron deficiency anemia in children from Makhachkala, occurring in about 87% of cases (P < 0.05). This relationship is substantiated by the analysis of medical records from children aged 2 to 17 from hospitals in both Northern and Central Dagestan, highlighting the connection between iron deficiency anemia and the low fluoride levels in drinking water. Further studies into the oral health of children have shown that the incidence and severity of caries in deciduous teeth are greater in the Northern than in the Central Zone of Dagestan. Moreover, conditions such as cheilitis, aphthous stomatitis, and desquamative glossitis are frequently observed in children during the stages of temporary tooth occlusion, affecting on average 38.5% of cases, and this prevalence increases to 78.2% during the mixed and permanent occlusion stages.Conclusion. The conducted studies revealed that the drinking water supplied to the Dagestan population has elevated permissible levels of iron and arsenic. Additionally, there is a noted deficiency of fluoride, zinc, and copper, as well as low water hardness. Research into the quality of drinking water and the health impacts on the pediatric population of Dagestan established a correlation (R = 0.593) between unbalanced water, dietary intake, the severity of dental caries, and reduced immunity in children. High levels of arsenic, germanium, and molybdenum in the water and children's hair contribute to cumulative health effects. Environmental pollution is also linked to a rise in oral health issues, iron deficiency anemia, and broader health problems. Analyzing the chemical composition of children's hair serves as a diagnostic tool for detecting and preventing diseases related to deficiencies and excesses of macro- and microelements.

Exposure to Trace Elements Through <i>Rauwolfia vomitoria</i> and <i>Argemone Mexicana,</i> Two Medicinal Plants at Hahotoé-Kpogamé, a Polluted Area in Southern Togo

Background: Herbal drugs and mineral elements are well established for their therapeutic benefits against diseases and nutritional importance in human health. Medicinal plants contain toxic metabolites which, once consumed, become a formidable source of disease. Accumulation of toxic industrial effluents in soil, air and water is continuously increasing due to fast urbanization and intensive environmental pollution. Elements like lead (Pb), cadmium (Cd), uranium (U), arsenic (As) which are not used by the plants directly but accumulate in the plants are detrimental to human health when consumed. This study aims to investigate the level of trace elements through the use of two medicinal plants in a polluted area in southern Togo. The trace elements analysis in the powder of the <i>Rauwolfia vomitoria</i> and <i>Argemone Mexicana</i> leaves, was carried out by the method and protocol described by Acme Laboratory using PerkinElmer ELAN 9000 Inductively Coupled Plasma Mass Spectrometry (ICP- MS). The result of trace elements concentrations (ppm) ranges revealed, as follows: Cadmium (0.8-1.5), Antimony (0.17-0.9), Arsenic (10.85-15.25), Lead (11.31-13.33), Iron (21.02-25.13), Manganese (84.5-140), Calcium (22.39-31.81), Zinc (73.1-82.6), Uranium (0.01-0.04) and Thorium (0.15-1.05) are significantly higher than the World Health Organization maximum permissible limit. These results suggested that the leaves of the two medicinal plants have contaminated by the trace elements. More toxicological activities need to be conduct in the area to find out the toxicity level of contaminants in herbal raw materials in the area.

Evaluating the properties of deinking paper sludge from the Mediterranean area for recycling in local areas as a soil amendment and to enhance growth substrates

AbstractRecycling of paper generates large quantities of paper sludge that is rich in organic matter and can be exploited to counteract organic matter loss in agricultural soils, especially in some geographical areas, such as the Mediterranean. In order for deinking paper sludge (DPS) to be recycled, chemical and physical characterizations are required along with an analysis of possible contaminants. DPS from Italy and Tunisia, resulting from various deinking processes, were analyzed and compared in terms of their chemical properties (pH, OM, total N, C/N ratio, mineral nutrients, and trace metals), surface chemistry [diffuse reflectance infrared Fourier transform (DRIFT) spectroscopy and Fourier-transform infrared (FTIR) spectroscopy], and thermal stability [thermogravimetric analysis (TGA)]. The aim was to improve their use as amendments in soils or growth substrates. Elemental analysis revealed higher carbon concentrations in the Tunisian DPS and similar nitrogen contents, high mineral nutrient levels, and potentially toxic trace element levels below the limits allowed for soil amendment. No evidence was found for the presence of organic pollutants, pathogens, or toxic heavy metals. Surface chemical analysis revealed comparable materials rich in aromatic, phenolic, aliphatic, and polysaccharide structures along with clay minerals and carbonates. The thermal analysis revealed similar decomposition temperatures for the organic matter. Practical implications of the results are discussed, highlighting the similar properties of sludge following ink removal by different processes and the need to integrate the N content in order to be able to employ sludge as an amendment in soil and growing media. Given the similarity of the compositions of the materials, appropriate DPS management is key to improving soil fertility, reducing paper waste disposal, and implementing a circular economy in the Mediterranean, where climate change is having a significant impact.

Serum vitamins and trace elements in vitiligo patients: A systematic review and meta‐analysis of observational studies

AbstractVitiligo is one of the most common pigmentary skin disorders, which significantly impacts the quality of life. The aetiology and pathophysiology of vitiligo are still unclear, but one of the proposed mechanisms is oxidative damage interrupting melanogenesis. The purpose of this study was to demonstrate the serum levels of trace elements and vitamins and to systematically review the evidence comparing vitiligo patients with a healthy group. We comprehensively retrieved all studies related to vitiligo and the serum levels of vitamins and minerals from databases such as PubMed, EMBASE, Scopus, Web of Science, Magiran, SID and ISC up to December 2022. Quality assessment and data extraction were conducted by two independent reviewers. Pooled standard mean differences with 95% confidence intervals were estimated using random‐effects models. Our meta‐analysis revealed no significant differences in serum levels of Vitamin B12 and copper. It was concluded that serum concentrations of Vitamin D, Vitamin E, and zinc were lower in vitiligo patients. Conversely, these patients exhibited higher levels of selenium and folic acid compared with healthy individuals. These results might affect the potential use of vitamin and mineral supplementation in vitiligo treatment.

Distribution of urinary trace element exposure and dietary sources in women over 50 in an agricultural region- A community-based KoGES cohort study

BackgroundThere is a noticeable lack of information on the levels of both non-essential and essential trace elements in women aged over 50. The main objective of this study is to investigate trace element concentrations and explore the influence of sociodemographic factors and dietary sources of exposure in this demographic. MethodsWe analyzed 19 trace elements, including manganese, cobalt, copper, zinc, molybdenum, chromium, nickel, arsenic, strontium, cadmium, tin, antimony, cesium, barium, tungsten, mercury, thallium, lead, and uranium, using ICP-MS and mercury analyzer. Urine samples were obtained from a cohort of 851 women aged over 50 who participated in the 8th KoGES-Ansung study (2017–2018). Multiple linear models were employed to explore associations between urinary trace element concentrations and sociodemographic factors and dietary sources of exposure. We used K-means clustering to discern patterns of exposure to trace elements and identify contributing factors and sources. ResultsOur findings indicate higher concentrations of molybdenum (Mo), arsenic (As), cadmium (Cd), and lead (Pb) in our study population compared to women in previous studies. The study population were clustered into two distinct groups, characterized by lower or higher urinary concentrations. Significant correlations between age and urinary concentrations were observed in Ni. Smoking exhibited positive associations with urinary Cd and As. Associations with dietary sources of trace elements were more distinct in women in the high-exposure group. Urinary antimony (Sb) was positively linked to mushroom and egg intake, As to mushroom and fish, and Hg to egg, dairy products, fish, seaweed, and shellfish. ConclusionsOur study underscores the significant gap in understanding urinary concentrations of trace elements in women aged over 50. With higher concentrations of certain elements compared to previous studies and significant correlations between age, smoking, and specific food sources, it is imperative to address this gap through targeted dietary source-specific risk management.

Metals and metalloid in medicinal plants: occurrence and risk assessment to human health

Aim: This study was aimed at determining the levels of trace elements in six medicinal plants of tropical origin. Methods: The levels of As, Cd, Co, Cu, Fe, Mn, Ni, Pb, and Zn in Albizia glaberrima (AG), Aristolochia ringens (AR), Brysocarpus coccineus (BC), Ipomoea asarifolia (IA), Sansevieria liberica (SL), and Telfairia occidentalis (TO) were determined using an inductively coupled plasma-mass spectrometry. The estimated dietary intakes of the metals, hazard quotients (HQ), and hazard index (HI) were calculated. Results: The highest levels of Cd, Pb, Zn, and Fe were detected in IA. BC had the highest levels of Mn and Ni while AR had the highest levels of Cu, Co, and As. However, the levels of the metals were mostly below the permissible limits in the plants. The estimated dietary weekly intakes (EWIs) were below the provisional tolerable weekly intake for each chemical element. The EWIs range values were 21.566–643.114 µg/kg per day (kg is the unit of body weight), 0.008–1.529 µg/kg per day, 0.6–7.815 µg/kg per day, 67.569–215.889 µg/kg per day, 4.305–185.451 µg/kg per day, 0.225–1.704 µg/kg per day, 1.03–10.2 µg/kg per day, 0.933–2.286 µg/kg per day, and 62.554–854.4 µg/kg per day for Cu, Cd, Pb, Zn, Mn, Co, Ni, As, and Fe, respectively. The HQ values of the elements were less than 1 except for Cu in AR (1.321). The values of lifetime cancer risks exceeded the permissible limit in all the plant materials. Conclusions: The findings from the study revealed that the consumption of TO, SL, and AG for medicinal purposes has no inherent non-carcinogenic toxicity while the consumption of AR, IA, and BC has some risks of non-carcinogenic toxic. However, the six plant materials showed inherent risks of carcinogenic events, as such their use for medicinal purposes must be cautious, maybe by reducing both the ingestion rate and the frequency of intake.

Spatial distribution of trace and rare earth elements of bottom sediments in Lake Ostrowite, Bory Tucholskie National Park, Poland

AbstractLake pollution has attracted concerns worldwide; especially the excessive accumulation of trace elements (TEs) and rare earth elements (REEs) in bottom sediments can pose a serious threat to ecosystem health. However, there is still a knowledge gap on the level of sediment pollution in lakes isolated from the direct impact of pollution sources, their spatial variability, and also on the factors influencing this state. The aim of this study is to investigate the level and spatial variability of TEs and REEs concentrations, as well as to determine their source and the factors determining their distribution in the bottom sediments of Lake Ostrowite. Lake Ostrowite is the largest and deepest water body located in the Bory Tuholskie National Park (in northern Poland), which completely isolates the lake from the direct impact of pollution sources. The study covered analyses of 32 surface samples of bottom sediments. The concentrations of 24 TEs and 14 REEs were determined using inductively coupled plasma mass spectrometry (ICP‐QQQ‐MS). The assessment of the enrichment of bottom sediments in TEs and REEs employed geochemical background values (GBV) that provided the basis for the calculation of relative concentrations and geochemical indices. The determination of their sources and supply routes was based on the cluster analysis and principal component analysis. The obtained results point to the enrichment of the bottom sediments with TEs and REEs. Relative concentration values of TEs and REEs in reference to geochemical background values were in ranges from 0.01 to 7.31, at an average of 0.99, and from 0.03 to 4.29, averaging 1.76, respectively. The enrichment factor values show moderately severe enrichment of sediments at the study sites. This was primarily determined by the concentrations of Ag (from the TEs group) and Lu (from the REEs group). The metal pollution index values showed an approximate spatial distribution of points in terms of the presence of TEs and REEs. The lowest concentrations of TEs and REEs occurred on the eastern shore of the western basin of Lake Ostrowite. TEs and REEs concentrations in sediments are positively correlated with the content of organic matter and depth and negatively correlated with distance of the sampling point from the river outflow from Lake Ostrowite. On the eastern shore of the western basin, TEs and REEs concentrations are additionally shaped by wind, predominantly from the western direction. With water wave action, organic matter is transported to the central part of the western basin, where it is accumulated. Since the lake is isolated from point and nonpoint pollution sources, relevant from a biogeochemical point of view are dry and wet depositions from the atmosphere as well as aquatic vegetation, shoreline vegetation, forest litter, soil, and groundwater.

Comparison of trace elements in peripheral blood and bone marrow of newly diagnosed multiple myeloma patients.

Trace elements are essential micronutrients for the human body. Their roles are indispensable, as they are involved in a wide range of vital biological processes. In this study, we aimed to evaluate alterations in trace elements in the blood and bone marrow serum of patients with newly diagnosed multiple myeloma (NMM). The levels of zinc (Zn), copper (Cu), iron (Fe), manganese (Mn), magnesium (Mg), selenium (Se), arsenic (As), boron (B), nickel (Ni), silicon (Si) and chromium (Cr) were analyzed in the venous blood samples of the patient group comprising 70 patients with NMM (41 males and 29 females) and compared to those in the control group comprising 30 individuals (18 males and 12 females). In addition, trace element levels were analyzed in bone marrow samples from the patient group. Blood and bone marrow serum levels were quantified using inductively coupled plasma optical emission spectrometry. When the blood samples of the patient and control groups were compared: Zn (p = 0.011), Fe (p = 0.008), Mn (p = 0.046), Se (p < 0.001), As (p < 0.001), Ni (p < 0.001) and Cr (p < 0.001) levels were significantly higher in the patient group than in the control group. Higher Zn, Fe, Mn, Se, As, Ni and Cr levels in the NMM patients suggest that alterations of trace elements could be predisposing factor that initiates the malignant process. The relationship between malignancies and trace elements is crucial for the development of adjuvant therapy strategies and preventive medicine and as biomarkers for cancer diagnosis. Therefore, there is a need for studies examining the relationship between hematological malignancies and trace elements.

Distribution, ecological, and health risk assessment of trace elements in the surface seawater along the littoral of Tangier Bay (Southwestern Mediterranean Sea)

In the current study, an environmental assessment of surface seawater in Tangier Bay was conducted by analyzing physicochemical parameters and trace elements, such as As, Cr, Zn, Cd, Pb, and Cu. The results showed mean concentrations (μg/l) of 22.50 for As, 0.46 for Cr, 8.57 for Zn, 15.41 for Cd, 0.23 for Pb, and 1.83 for Cu. While most trace elements met the guidelines, elevated levels of Cd raised concerns about long-term exposure. Pollution indices, including the contamination factor, degree of contamination, and water quality index, indicate the impact of human activities, dividing sites into arsenic‐cadmium contamination, wastewater influence, and low pollution levels. Statistical methods, such as ANOVA, revealed no significant differences in trace element levels across the bay. PCA and HCA revealed that Cr, Cu, and Zn originated from common anthropogenic sources, whereas Pb and Cd originated from distinct sources. As indicates that natural geological processes influence its origin.

Relationships between trace elements and cognitive and depressive behaviors in sprague dawley and wistar albino rats.

Introduction: This study investigates the effects of social isolation on mental health and cognitive functions in Sprague Dawley (SD) and Wistar Albino (WIS) rat strains, prompted by the heightened awareness of such impacts amid the COVID-19 pandemic. This study aims to explore the impact of social isolation on memory, learning, and behavioral changes in middle-aged SD and WIS rat strains and to investigate cortical trace element levels, seeking potential correlations between these levels and the observed behavioral responses to social isolation. Methods: Four groups of 14-month-old male rats were established: control and isolated SDs and WIS rats (CONT-SD, ISO-SD, CONT-WIS, ISO-WIS). Morris Water Maze and Porsolt Forced Swimming tests were conducted for behavioral assessment. Following behavioral tests, rats were sacrificed under general anesthesia, and cortices were isolated for analysis of macro and trace element levels (ICP/MS). Results: In behavioral tests, CONT-SD rats exhibited superior performance in the Morris Water Maze test compared to CONT-WIS rats, but displayed increased depressive behaviors following social isolation, as evident in the Porsolt Forced Swimming test (p < 0.05). ISO-SD rats showed elevated levels of Co and Cu, along with reduced levels of Cs and As, compared to ISO-WIS rats. Moreover, isolation resulted in decreased Cu and Mo levels but increased Rb levels in WIS rats. Comparison of trace element levels in naïve groups from different strains revealed lower Zn levels in the WIS group compared to SD rats. Discussion: The findings suggest that the SD strain learns faster, but is more susceptible to depression after isolation compared to the WIS strain. Increased Co and Cu levels in ISO-SD align with previous findings, indicating potential trace element involvement in stress responses. Understanding these mechanisms could pave the way for preventive treatment strategies or therapeutic targets against the consequences of stressors, contributing to research and measures promoting a balanced diet to mitigate neurobehavioral abnormalities associated with social isolation in the future.

A case-control study on asthma and obese patients: Influence of lifestyle patterns, serum trace elements, heavy metals, and total antioxidants

Background and aimAsthma is a chronic airway hyperresponsiveness disorder and Obese people have greater rates of asthma incidence and prevalence. Obesity, a complex condition, can cause nutritional metabolic problems that change trace elements and minerals. Trace element and antioxidant levels affect asthma aetiology. In this study, we aim to determine the serum levels of trace elements Zn, Fe, Cu, Mg, Co, Ni, Pb, Cd, and Cr, total antioxidants (TAS), and lifestyle that determine specific clinical conditions in asthma and obesity patients from Vellore City (Tamil Nadu, India). MethodsA case-control study to determine the level of the serum trace elements with 838 subjects (n = 242 asthma patients, n = 140 asthmatic obese, n = 185 obese patients, and n = 271 controls) between the ages of 20 and 60 years was carried out. Asthma was diagnosed based on the clinical examination and pulmonary function tests. Trace element levels were determined by atomic absorption spectrophotometry (AAS) in serum, and a DPPH-free radical scavenging assay was used to determine the total antioxidant capacity level in serum. ResultIn asthma male patients, serum levels of Zn, Fe, Cu, Mg, and TAS were significantly lower and Pb, Cd, and Cr significantly higher, whereas in female asthma patients, serum levels of Zn, Fe, Mg, and TAS were significantly lower and Pb significantly higher. In asthmatic obese male patients, Fe, Cu, and TAS were significantly lower, and Pb, Cd, and Co were significantly higher; in asthmatic obese female patients, Zn, Fe, Cu, Mg, and TAS were significantly lower, and Ni was significantly higher. In obese male patients, Zn, Fe, Cu, and TAS were significantly lower and Cd was significantly higher, and in obese female patients, Zn, Fe, Cu, Mg, and TAS were significantly lower. ConclusionThe influence of the level of trace elements, heavy metal, total antioxidant, and the lifestyle patterns, may increase the risk of asthma and obesity.

Risk of Trace Element Imbalance in Cases of Occupational Allergic Diseases

Introduction: The relevance of the study is attributed to the lack of knowledge of the mechanisms of development and specifics of the clinical picture of occupational allergic diseases. Objective: To establish the levels of essential trace elements in biological substrates of patients with occupational allergies. Materials and methods: In 2014–2018, we analyzed zinc and copper levels in urine, blood serum, and lymphocytes of patients with occupational allergic skin and respiratory diseases by the atomic absorption method. Relative risk was calculated using a four-field contingency table. Results: In patients with work-related allergic contact dermatitis and bronchial asthma, zinc and copper concentrations in blood serum increased while urinary excretion of these elements decreased. Quantitative patterns of the concentrations of trace elements in body fluids of the patients with skin and respiratory allergies were unidirectional compared to the reference group. Relative risk values showed that lower levels of copper in urine and zinc in blood serum and lymphocytes, as well as higher serum copper indicated the risk of trace element imbalance in the body. Conclusion: The risk of trace element imbalance due to occupational allergic diseases is associated with impaired copper and zinc balance. Our findings prove that the levels of microelements are additional factors that aggravate the course of occupational allergic disorders.

Dried fish-filled rice ball: A new ready-to-eat product, consumer preferences and nutritional aspects

Due to time constraints, demands for ready-to-eat products are skyrocketing. A traditional Bangladeshi meal such as rice and fish is often found troublesome to be eaten in workplaces while taking excessive preparation time. With this in mind, a nutritious value-added product, namely, rice ball filled with mixed dried small indigenous species (SIS) fish powder was developed in the laboratory. Eight separate compositions of the product were prepared by combining two types of cooked rice, and mixed dried fish stuffing consisting of Amblypharyngodon mola, Puntius sophore and Corica soborna. Four categories of panelists scored the prepared products on the basis of the attributes and overall likings. Statistical tests proved the ball prepared from non-gruelled rice and oven dried fish powder (RB6) to be the preferred one while the products varied in odor, mouthfeel, taste and texture. The study revealed that plain rice now contained more protein (4.73 ± 0.20 % to 7.82 ± 0.15 %) and lipid (1.44 ± 0.20 % to 3.73 ± 0.07 %) due to the addition of dry fish powder. Taking the quality and microbial parameters as well as the trace element level into consideration, the developed product showed negligible quality compromisation while pH was nearly neutral. The present study suggests that dried fish-filled rice ball could be a viable commercial product with high nutritional and quality attributes.

The Determination and evaluation of trace elements in the blood of radiography workers using graphite furnace atomic absorption spectrometry

This study aimed to evaluate the potentially toxic effects of trace elements in the blood of Iraqi medical radiography workers by analyzing them through GF-AAS. The study involved 50 male blood radiography workers from the medical imaging field at Al-Shatrah General Hospital in Thi-Qar City, Iraq. All workers were aged between 35-50 years and had worked for less than 10 years. The study compared these workers with 50 healthy men. The study found a significant increase in the levels of Cu, Pb, Cd, and Ca among radiography workers compared to the healthy control group, while Zn and Se levels decreased significantly. Moreover, Specificity and confidence interval (95%) were estimated via the receiver operating characteristic curve (ROC). The study provided conclusive evidence of disturbances in the levels of trace elements in the blood of radiographer workers, which makes them more susceptible to many diseases because of their radiation exposure. which portends the more preventive measures of radiation. The linear range of Cd, Cu, Zn, Se and Pb in human serum were obtained 0.2-6.0 µg dL-1, 6.0-200 µg dL-1, 8.0-200 µg dL-1, 10-250 µg dL-1, 4-120 µg dL-1 by GF-AAS after dilution samples with DW up to 20 (n=10, RSD&lt; 5%).

Maternal transfer of trace elements to shark eggs and their dietary assimilation efficiencies

Dogfish (Scyliorhinus canicula) transferred trace elements (110Ag, 109Cd, 54Mn and 75Se) from their diet to eggs, and their components (yolk and embryo, case and jelly) at greatly varying rates. Trace element levels in eggs showed positive linear relationships (p < 0.001; r2–0.83-0.91) with their cumulative rates of maternal ingestion over 61 days (maternal-to-egg transfer rates: mTFs). These mTFs varied by 2–3 orders of magnitude, with 54Mn > 110Ag > 75Se > 109Cd, and their range encompassed those previously measured for 60Co, 65Zn, 241Am and 134Cs. For six of the eight trace elements, their mTFs were significantly influenced (p < 0.05; r2 = 0.72) by both their dietary assimilation efficiency and their location within the egg (case). In contrast, both 110Ag and 54Mn greatly exceeded the mTFs predicted by this multiple regression model by one and 2–3 orders of magnitude, respectively, and were predominantly transferred to the egg case. Among elements, contrasting rates of transfer and percentage distributions in egg components imply differing ecotoxicological and radiological detriments to the developing embryo.

Root-exuded specialized metabolites reduce arsenic toxicity in maize

By releasing specialized metabolites, plants modify their environment. Whether and how specialized metabolites protect plants against toxic levels of trace elements is not well understood. We evaluated whether benzoxazinoids, which are released into the soil by major cereals, can confer protection against arsenic toxicity. Benzoxazinoid-producing maize plants performed better in arsenic-contaminated soils than benzoxazinoid-deficient mutants in the greenhouse and the field. Adding benzoxazinoids to the soil restored the protective effect, and the effect persisted to the next crop generation via positive plant-soil feedback. Arsenate levels in the soil and total arsenic levels in the roots were lower in the presence of benzoxazinoids. Thus, the protective effect of benzoxazinoids is likely soil-mediated and includes changes in soil arsenic speciation and root accumulation. We conclude that exuded specialized metabolites can enhance protection against toxic trace elements via soil-mediated processes and may thereby stabilize crop productivity in polluted agroecosystems.

Assessment of trace element and mineral levels in students from Turkmenistan in comparison to Iran and Russia

The objectiveOf the present study was to assess essential trace element and mineral levels in serum, hair, and urine of healthy first-year students from Turkmenistan (n = 73) in comparison to students from Iran (n = 78) or Russia (n = 95). Materials and methodsExamination of foreign students was performed within two days after arrival to Russia during medical examination prior admission to RUDN University. Serum, hair, and urine trace element and mineral levels were assessed with inductively coupled plasma-mass spectrometry (ICP-MS). ResultsThe data demonstrate that the levels of trace elements and minerals in students from Turkmenistan share high similarity to elemental profiles of students from Iran. In comparison to students from Russia, subjects originating from Iran and Turkmenistan are characterized by lower serum cobalt (Co), chromium (Cr), copper (Cu), manganese (Mn), molybdenum (Mo), selenium (Se), vanadium (V), zinc (Zn) levels, higher urinary Cr, Cu, Fe, Mn, V, and Zn, lower urinary Co and hair Mo, Se, and Zn content. Concomitantly, students from Turkmenistan were characterized by lower urinary Cr and Cu, serum Cu and V levels, higher circulating Zn concentration, as well as the lower hair Cr, Cu, iodine (I) and magnesium (Mg) content in comparison to Iranian subjects. The discriminant analysis demonstrated that hair, serum, and urinary trace element and mineral levels contributed to complete discrimination between the groups of students from different countries. ConclusionsThe high similarity of trace element and mineral status of students from Turkmenistan and Iran is expected to be mediated by similar geochemical conditions in the bordering countries.

Integrated transcriptome and proteome analysis reveals the unique molecular features and nutritional components on the muscles in Chinese Taihe black-bone silky fowl chicken.

The Taihe Black-Bone silky fowl chicken (BB-sfc) is a renowned dietary and medicinal chicken globally recognized for its high nutritional and medicinal value. Compared to the local Black-Bone black-feathered chicken (BB-bfc), the Taihe silky fowl chicken has higher levels of amino acids, trace elements, and unsaturated fatty acids in their muscles, which offer anti-aging, anti-cancer, and immune enhancing benefits. Despite this, the unique nutritional components, genes, and proteins in Taihe silky fowl chicken muscles are largely unknown. Therefore, we performed a comprehensive transcriptome and proteome analysis of muscle development between BB-sfc and BB-bfc chickens using RNA-Seq and TMT-based quantitative proteomics methods. RNA-Seq analysis identified 286 up-regulated genes and 190 down-regulated genes in BB-sfc chickens, with oxidoreductase activity and electron transfer activity enriched in up-regulated genes, and phospholipid homeostasis and cholesterol transporter activity enriched in down-regulated genes. Proteome analysis revealed 186 significantly increased and 287 significantly decreased proteins in Taihe BB-sfc chicken muscles, primarily affecting mitochondrial function and oxidative phosphorylation, crucial for enhancing muscle antioxidant capacity. Integrated transcriptome and proteome analysis identified 6 overlapped up-regulated genes and 8 overlapped down-regulated genes in Taihe silky fowl chicken, related to improved muscle antioxidant status. Taken together, this research provides a comprehensive database of gene expression and protein information in Taihe Black-Bone silky fowl chicken muscles, aiding in fully exploring their unique economic value in the future.
