Corrected Serum Ionized Calcium as a Risk Factor Related to Adult Dyslipidemia.

BackgroundDyslipidemia is a significant threat to global public health due to its pivotal role as a cardiovascular disease (CVD) risk factor. Calcium is a critical nutritional element required for electrical signal transduction and muscle and heart function, and calcium supplementation is widespread in the general population. However, associations between serum calcium and serum lipid profiles remain conflicting. Considering ionized calcium [Ca(2+)] is the best measure of active serum calcium and the lack of Ca(2+) analyzers, we aimed to examine the independent and joint associations between serum ionized calcium corrected by albumin ([Ca2+]corr) and the known modifiable risk factors and dyslipidemia.MethodsWe collected physical examination records, including demographic, anthropometric, laboratory tests, and clinical characteristics from individuals who had health checkups in 2019 at the health examination center of the First Affiliated Hospital of China Medical University. Subjects were categorized into Q1–Q4 groups using [Ca2+]corr quartiles, and odds ratios (ORs) with 95% confidence intervals (CIs) for dyslipidemia and associated components were calculated using logistic regression. We also performed non-linear and threshold effect analyses of [Ca2+]corr and triglyceride (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and non-high-density lipoprotein cholesterol (Non-HDL-C) levels.FindingsOf 5,416 individuals aged 18–92 years, multivariable-adjusted models showed that ORs for dyslipidemia increased gradually with elevated [Ca2+]corr levels. Logistic regression analyses demonstrated that [Ca2+]corr levels were associated with the increased odds of dyslipidemia (per 1 mmol/L increase: OR = 3.53, 95% CI: 1.56–8.00, P < 0.001). When compared with individuals in the Q1 group, those in groups Q3 and Q4 had significantly higher dyslipidemia odds (ORQ3 vs. Q1 = 1.20, 95% CI: 1.01–1.42; ORQ4 vs. Q1 = 1.31, 95% CI: 1.10–1.56, all P < 0.05). Furthermore, a linear, positive relationship between [Ca2+]corr levels and dyslipidemia odds was observed (P for non-linear trend = 0.506), and the optimal cut-off point of [Ca2+]corr for dyslipidemia management was 2.26 mmol/L. A modifiable effect of albumin on the relationship between [Ca2+]corr and dyslipidemia odds was also found (P for interaction = 0.014). High [Ca2+]corr levels were positively associated with elevated TC, LDL-C, and Non-HDL-C but inversely associated with decreased HDL-C odds. Moreover, Locally weighted regression (Loess) analyses showed a non-linear, positive relationship between [Ca2+]corr and TG, TC, HDL-C, LDL-C, and Non-HDL-C levels.InterpretationCorrected serum ionized calcium was positively associated with increased odds of dyslipidemia and elevated TC, LDL-C, and Non-HDL-C, but inversely associated with the odds of decreased HDL-C.

The potential of combining laser-induced breakdown spectroscopy and Raman spectroscopy data for the analysis of wood samples

We report on combining the surface analysis technique of Laser-induced Breakdown Spectroscopy (LIBS) with Raman spectroscopy. The combination of both techniques enables to study the chemical composition of the sample in a broader context when combining elemental and molecular information. Obtained elemental and molecular spectra are characteristic for individual biological samples (e.g., organs and cells) and are considered as a fingerprint. In this study, Raman spectroscopy is used for the detection of important molecular complexes in selected wood samples, e.g., accurate lignin and cellulose content on distinct spots of the sample surface. We chose Raman as a standard reference technique that is used for the lignin/cellulose ratio estimation. To complement the molecular information, LIBS technique was employed for the imaging of essential nutrients, e.g., Ca, Na, and K. Consequently, the contribution from both analytical techniques was combined and changes in the molecular content were visually correlated to the abundance of nutrition elements and show a direct dependence between the two signal responses. Thus, we can get specific answers to relation of lignin and cellulose formation with nutrients within the plant tissue. This evidence may then be helpful for the study of the effect of various environmental and stress factors.

Identification of Near Geographical Origin of Wolfberries by a Combination of Hyperspectral Imaging and Multi-Task Residual Fully Convolutional Network.

Ningxia wolfberry is the only wolfberry product with medicinal value in China. However, the nutritional elements, active ingredients, and economic value of the wolfberry vary considerably among different origins in Ningxia. It is difficult to determine the origin of wolfberry by traditional methods due to the same variety, similar origins, and external characteristics. In the study, we have for the first time used a multi-task residual fully convolutional network (MRes-FCN) under Bayesian optimized architecture for imaging from visible-near-infrared (Vis-NIR, 400–1000 nm) and near-infrared (NIR-1700 nm) hyperspectral imaging (HSI) technology to establish a classification model for near geographic origin of Ningxia wolfberries (Zhongning, Guyuan, Tongxin, and Huinong). The denoising auto-encoder (DAE) was used to generate augmented data, then principal component analysis (PCA) was combined with gray level co-occurrence matrix (GLCM) to extract the texture features. Finally, three datasets (HSI, DAE, and texture) were added to the multi-task model. The reshaped data were up-sampled using transposed convolution. After data-sparse processing, the backbone network was imported to train the model. The results showed that the MRes-FCN model exhibited excellent performance, with the accuracies of the full spectrum and optimum characteristic spectrum of 95.54% and 96.43%, respectively. This study has demonstrated that the MRes-FCN model based on Bayesian optimization and DAE data augmentation strategy may be used to identify the near geographical origin of wolfberries.

LOCAL NON-TRADITIONAL RESOURCES AND AGRICULTURAL WASTE AS SOURCES OF NUTRITION ELEMENTS OF PLANTS

The purpose of the study is a search for local cheap sources of biophilic plant nutritional elements and a possibility of production of organomineral fertilizers based on them, which are agronomically effective, environmentally safe and economically feasible. To achieve this goal, field experiments were carried out on the basis of the experimental field of Ulyanovsk State Agrarian University named after P.A. Stolypin and SPK Kolkhoz named after Kalinin, Veshkaimsky district, Ulyanovsk region. The effectiveness of diatomite from Inza deposit and zeolite from the Maina deposit of Ulyanovsk region were studied in field experiments as fertilizers for vegetable crops and millet in pure form, as well as in combination with poultry manure. All experiments were conducted with strict compliance with methodological requirements; analyzes of soil and plant samples were carried out in accordance with relevant state standards. It was found that, high-siliceous rocks such as diatomite and zeolite are of great interest in Ulyanovsk region as sources of plant nutrients, and poultry manure is important agricultural waste. Studies showed that diatomite and zeolite significantly improve soil nutritional regime. Thus, introduction of diatomite into the soil as a fertilizer of millet at a dose of 3 t/ha led to an increase of mineral nitrogen in the arable layer of leached black soil by 1.9 mg/kg, available phosphorus by 7 mg, and potassium by 12 mg/kg of soil. Improvement of soil nutritional regime with introduction of siliceous rocks influenced millet yield: in case of diatomite application at a dose of 3 t/ha, the yield increase was 0.82 t/ha; zeolite at a dose of 0.5 t/ha - 0.33 t/ha ( 13 %). The effectiveness of siliceous rocks increased significantly when combined with poultry manure. Yield of cucumbers increased by 6.8 t/ha, tomatoes by 0.4 t/ha, carrots by 4.9 t/ha, table beetroot by 8.1 t/ha in case of diatomite application in combination with poultry manure compared to variant of its application in pure form.

Unrenowned facts of scientifc heritage of O.O. Izmailsky (devoted to the 170th birth anniversary)

O.O. Izmailsky was the frst to cover the issue of the origin of the Ukrainian steppes, their development stage, causes of droughts. The scientist developed scientifcally substantiated complex of organizational, agrotechnical and reclamation measures to fght droughts and further implemented them in agricultural practice. The experimentalist has shown that droughts are not caused by climate, in particular, annual amount of precipitation, but rather by the nature (cultural condition) of the feld surface and the soil structure. He pointed out the need for snow retention, developed and implemented effective measures for its implementation which are relevant today: fallows, mulching, cutting shafts with snow plows, etc. He recommended using artesian wells, artifcial relief creation, slopes terracing, dams and afforestation to resist drought. The scientist led the supporters of deep plowing promoted and implemented in the farms of Poltava and Kherson oblasts. The scientists warned that the human careless attitude to the progressing drying of Ukrainian steppes might result in turning it into a barren desert in the near future. O.O. Izmailsky proposed to organize a wide network of research felds and stations throughout Ukraine in order to address pressing issues of agriculture. He established the link between droughts and deflationary processes. One of the scientist’s immortal merits is his correct concluding that it is the inability of the sprayer, unstructured and dusty soil to absorb, accumulate and give back water and its nitrogen and ash nutrition elements to plants that cause of draughts and hence crop failures in the southern oblasts rather than the sum of the precipitation that falls during a year. The scientists proved the need for support soil surface in a loose state and deepening of the arable layer to resist drought. He developed a set of measures to fght soil erosion. The scientist considered it is not the climate but the soil surface change that is the main reason for the depletion of the Ukrainian steppes to water. He pointed out that water retention plays an important role in the water regime improving ability, moisture capacity, structural condition, water permeability and other agrophysical soil properties, along with mulching the feld with plant residues. The scientists has also explained the reasons for more humid climate of domestic steppes in the past. He pointed out the ways to create a sustainable, environmentally friendly, economically viable agriculture that are adapted to the steppe landscapes to the largest extent. Key words: steppe, droughts, soil, humidity, steppe agriculture, snow retention, cultural condition, cultivation.

Nutritional components as mitigators of cellular senescence in organismal aging: a comprehensive review.

The process of cellular senescence is rapidly emerging as a modulator of organismal aging and disease. Targeting the development and removal of senescent cells is considered a viable approach to achieving improved organismal healthspan and lifespan. Nutrition and health are intimately linked and an appropriate dietary regimen can greatly impact organismal response to stress and diseases including during aging. With a renewed focus on cellular senescence, emerging studies demonstrate that both primary and secondary nutritional elements such as carbohydrates, proteins, fatty acids, vitamins, minerals, polyphenols, and probiotics can influence multiple aspects of cellular senescence. The present review describes the recent molecular aspects of cellular senescence-mediated understanding of aging and then studies available evidence of the cellular senescence modulatory attributes of major and minor dietary elements. Underlying pathways and future research directions are deliberated to promote a nutrition-centric approach for targeting cellular senescence and thus improving human health and longevity.

Assessment of macro and micro elements present in three commonly eaten vegetables in Nigeria

The study investigated the nutritive elements of four species of Basella and two other commonly eaten vegetables (Amaranthus hybridus and Talinum triangulare). The vegetables are found throughout the year. The mineral compostion of the vegetables was carried out using standard procedures to determine which of these would be of more health benefit to the consumers. Leaves were collected at the initiation of flowering and air-dried under shade for 7 days after which they were kept in an oven at 60oC for 24 hours. These dried materials were mechanically powdered and stored in airtight containers until used for analysis. The phosphorous content of the vegetables ranged from 83.95±0.01 to 136.30±0.01 mg/100g. The potassium content ranged from 733.20±17.7 mg/100g to 4084.20+0.03 mg/100g. Sodium content in the vegetables ranged from 89.25±0.04 to 241.50±0.02 mg/100g. Zinc content ranged from 8.00+2 mg/100g to 28.90+4 mg/100g. The mineral contents of the Basella forms are comparable to Amaranthus hybridus and Talinum triangulare. Overlap observed in the values of the nutrient elements suggests interspecies relationship. Copper was present in Basella rubra and Amaranthus hybridus, while Molybdenum was absent in all. This study revealed that the consumption of these vegetables is dependent on the dietary need of the users.

НОВЫЙ НЕИНВАЗИВНЫЙ СПОСОБ ОЦЕНКИ АЛИМЕНТАРНОЙ ОБЕСПЕЧЕННОСТИ СЕЛЕНОМ IN VIVO

Selenium (Se) is essential trace element in human nutrition. The aim of this study was to assess selenium nutritional status by analyzing Se frequency distribution in the long-term biological indicator tissue of hair (H∙Se) and in the short-term biological indicator tissue of whole blood (WB∙Se). Hair selenium was analyzed in 1073 apparently healthy adult Croats (339 ♂ and 734 ♀) and the whole blood selenium was analyzed in a random subsample of 91 ♂ and 143 ♀. Samples were analyzed by the ICP-MS at the Center for Biotic Medicine, Moscow, Russia. There were no significant gender dependent difference in the selenium adequate linear reference range which was (µg∙g1) for H∙Se 0.078–0.701 and for WB∙Se 0.120–0.200, respectively. Hair selenium concentrations below 0.078 and 0.120 for WB∙Se indicate selenium deficiency. The estimated upper adequate selenium limits for H∙Se and WB∙Se are set at 0.701 and 0.200 µg∙g1, respectively. The linear segment of the generated H∙Se logistic distribution sigmoid curve is considered to represent adequate Se intake range. This adequate selenium intake segment can be itself partitioned by a 60:30:10 percentage ratio into Sparsely adequate (♀ 0.078–0.405, ♂ 0.1740.474), Adequate (Optimal) (♀ 0.4050.573, ♂ 0.474–0.608), and Ample adequate segment (♀ 0.5730.623, ♂ 0.608–0.709). These reference dose data are essential for continuous monitoring of the selenium nutritional status and selenium supplementation medication The noninvasive selenium status assessment is especially important when dealing with a vulnerable segments of human population like pregnant and lactating women, and their infants. The Median Derivatives Bioassay provides a new public health asset for general medical practice.

The most productive of the studied varieties was the Belarusian variety Manifest, which ultimately had the maximum yield of seed material of the first field generation, which plays a paramount role for seed production. When studying the average coefficient of adaptability (Ka) in the conditions of the Pskov region, it was found that the most productive and promising varieties for growing in this region are Manifest and Lileya Belorusskaya with the highest coefficients of adaptability from 1.25-0.02 and with the use of liquid polymer fertilizer at a concentration of 25-30 mg / l.

Study of the responsiveness of new potato hybrids to various doses of mineral fertilizers

Potato is an agricultural crop with a high removal of mineral nutrition elements and is responsive to fertilizers. Therefore, it is necessary to provide a system of mineral fertilizers for it, which contributes to obtaining a high yield with good indicators of the quality of tubers and meeting the standards of sanitary and hygienic control for the content of nitrates in tubers. Studies of new potato hybrids for responsiveness to mineral fertilizers were carried out on experimental fields of the Institute of Agrobiotechnologies FRC Komi Science Center Ural Branch of the Russian Academy of Sciences (Russia, Republic of Komi, Syktyvkar). The object of the study is three mid-season hybrids that passed the competitive test based on the results of a four-year selection selection (2018-2021): 1992-14 (Udacha × Elmundo), 2000-60 (Colette × FZ 1867), 2139-5 (Courage × Aurora ). Hybrids were obtained from FRC Potato named after. A. G. Lorkha (Russia, Moscow region, township Korenevo). The zoned mid-early variety Nevsky was used as a standard. The study was carried out according to the following scheme: control - without fertilizers, dose 1 - N100P80K150, dose 2 - N150P120K225 and dose 3 - N200P160K300. As a result of studying the effect of mineral fertilizers in the cultivation of new promising potato hybrids, the highest complex efficiency of nitrogen, phosphorus and potassium doses in the combination of N100P80K150 was established. The use of this dose of fertilizers made it possible to obtain a significant increase in yield by 20-25% for the studied hybrids and standards, while the fractional composition of tubers changed in favor of the medium and large fractions, the content of dry matter, starch and vitamin C was maintained at the level of the variant without the use of fertilizers, while In this case, there was no excessive accumulation of nitrates in potato tubers.

The Key Role of Nutritional Elements on Sport Rehabilitation and the Effects of Nutrients Intake.

Adequate nutrition is of utmost importance for athletes, especially during rehabilitation after injury in order to achieve fast healing and return to sports. The aim of this narrative review is to define the proper nutritional elements for athletes to meet their needs and facilitate their fast return to sports after surgery or injury, as well as determine the effects of specific nutrients intake. Studies on antioxidants, which are substances that protect against free radicals, for the injured athlete are few and unclear, yet poly-phenols and especially flavonoids might improve healing and inflammation following an injury. Benefits of vitamin C or E on muscle damage are disputable in relevant studies, while optimal levels of vitamin D and calcium contribute to bone healing. Minerals are also essential for athletes. Other supplements suggested for muscle damage treatment and protein synthesis include leucine, creatine, and hydroxymethylbutyrate. Diets that include high-quality products, rich in micronutrients (like vitamins, minerals, etc.) bio-active compounds and other nutritional elements (like creatine) are suggested, while an individualized nutrition program prescribed by a trained dietitian is important. Further studies are needed to clarify the underlying mechanisms of these nutritional elements, especially regarding injury treatment.

The Synergistic Effect of Biochar-Combined Activated Phosphate Rock Treatments in Typical Vegetables in Tropical Sandy Soil: Results from Nutrition Supply and the Immobilization of Toxic Metals.

Sandy soils in tropical areas are more vulnerable to potential toxic elements as a result of their low nutrition. The composite addition of biochar and phosphate material is considered a promising method of immobilizing toxic metals in sandy soils, but the synergistic effects of this process still need to be further explored, especially in typical tropical vegetables. In this study, a pot experiment was conducted to evaluate the agronomic and toxic metal-immobilization effects of single amendments (phosphate rock, activated phosphate rock, and biochar) and combined amendments, including biochar mixed with phosphate rock (BCPR) and biochar mixed with activated phosphate rock (BCAPR), on vegetables grown in tropical sandy soil. Among these amendments, the composite amendment BCAPR was the most effective for increasing Ca, Mg, and P uptake based on water spinach (Ipomoea aquatica L.) and pepper (Capsicum annuum L.), showing increased ratios of 22.5%, 146.0%, and 136.0%, respectively. The SEM-EDS and FTIR analysis verified that the activation process induced by humic acid resulted in the complexation and chelation of the elements P, Ca, and Mg into bioavailable forms. Furthermore, the retention of available nutrition elements was enhanced due to the strong adsorption capacity of the biochar. In terms of cadmium (Cd) and lead (Pb) passivation, the formation of insoluble mineral precipitates reduced the mobility of these metals within the BCAPR treatments, with the maximum level of extractable Cd (86.6%) and Pb (39.2%) reduction being observed in the tropical sandy soil. These results explore the use of sustainable novel cost-effective and highly efficient bi-functional mineral-based soil amendments for metal passivation and plant protection.

Influence of the layland development technology on the water-physical and agrochemical properties of the soil of Central Siberia

Relevance. The disadvantages of steppe nature management include soil degradation, deficiency of mineral nutrition elements and other adverse phenomena. Similar processes are taking place in Siberia. Currently, the re-development of laylands is beginning and soil degradation is again manifested in the steppe regions of Khakassia. For the effective use of land resources, it is necessary to develop a technology for processing soil deposits in the arid steppe zone of the south of Central Siberia.Methods. The study of the effectiveness of soil treatment technologies of the erosive agroecological group of laylands was carried out in the arid steppe agrolandscape region of the Republic of Khakassia, located in the south of Central Siberia. The research was carried out for four years in the feed crop rotation link: a long-term (20-25 years) grain-grass layland — oats (corn) for green mass by the method of field experience of B.A. Dospekhov. Methods of water-physical and agrochemical studies were used in the performance of the work.Results. It is established that on long-term laylands (20-25 years) soil compaction, low moisture content and mineral nutrition elements are noted. The influence of the complex application of continuous herbicides (Tornado 500, Sprut Extra) and processing technology on the water-physical and agrochemical properties of the soil has been revealed. During summer tillage of a long-term layland and introduction of herbicide, there is an accumulation of moisture, nitrate nitrogen. In the arid steppe zone, the technology with tillage of a long-term layland to a depth of 18-20 cm increases the productivity of the feed crop rotation link by an average of 25.5-32.7% compared to technological operations involving small-scale processing (12-14 cm and 14-16 cm).
