Association between lipid accumulation product and the risk of colon cancer in adults: A population-based study.

The purpose of this study was to look into any potential connections between the occurrence of colon cancer and the condition of the body of lipid accumulation product (LAP) index. Using data from the 2009-2018 National Health and Nutrition Examination Survey (NHANES), we performed a cross-sectional analysis with 24,592 individuals. Utilizing multivariate logistic regression modelling, the relationship between LAP levels and colon cancer risk was investigated. Subgroup analysis, trend test, interaction test, and stratified smoothed curve were also carried out. LAP levels and colon cancer risk were positively correlated after controlling for potential covariates (OR = 10.56, 95% CI: 2.40-46.53), the findings of trend tests are statistically significant. In particular groups, subgroup analysis revealed a positive connection between LAP levels and the risk of colon cancer. The association between LAP levels and colon cancer risk was shown to be M-shaped in the group under 60 years old, inverted V-shaped in the female and no-diabetes groups, and inverted L-shaped in the smoking and no-hypertensive groups, according to stratified smoothed curve fitting. According to our findings, there is a strong correlation between LAP levels and the risk of colon cancer.

Association of dietary acid load with inflammatory markers, oxidative stress, and clinical features in patients with knee osteoarthritis

Knee osteoarthritis (KOA) is a prevalent chronic condition characterized by inflammation and oxidative stress, particularly in individuals over 40. Dietary factors, specifically dietary acid load (DAL), may influence these pathological processes. However, the relationship between DAL and inflammatory markers, oxidative stress, and clinical features in patients with KOA remains unexplored. This cross-sectional study involved 147 participants aged 40 and above diagnosed with moderate to severe bilateral primary KOA. Dietary intake was assessed using a validated food frequency questionnaire, and DAL was quantified using Potential Renal Acid Load (PRAL) and Net Endogenous Acid Production (NEAP) indices. Clinical symptoms were evaluated using the WOMAC Index. Biochemical markers of oxidative stress and inflammation were measured from serum samples. Higher PRAL and NEAP scores were associated with increased levels of thiobarbituric acid reactive substances (TBARS) and total oxidant status (TOS), indicating elevated oxidative stress. Additionally, serum levels of inflammatory markers, including TNF-α and hs-CRP, positively correlated with higher DAL scores. Clinical assessments revealed that increased PRAL scores were related to greater severity of symptoms as measured by the WOMAC Index. This study demonstrates a significant association between dietary acid load and markers of inflammation and oxidative stress in KOA patients. These findings suggest that dietary modifications aimed at reducing acid load may serve as a beneficial adjunctive strategy in managing KOA and improving patient outcomes.

Growth, productivity, quality and profitability of organic finger millet under cultivar and nutrient management options

Cultivars and nutrient management determine productivity and quality of the organic finger millet. A field trial was carried out during the kharif season 2022 at Binjhagiri, Bhubaneswar, Odisha comprising the four cultivars of finger millet and four nutrient management practices through organic manure combinations with split plot design replicated thrice. The four cultivars namely, C1- ‘Arjuna’, C2- ‘Bhairabi’, C3- ‘Chilika’ and C4- ‘Kalua’ were assigned to the main plots. Recommended dose of nitrogen (RDN) such as 50 kg ha-1 was supplied through varying percentage of organic manures namely, farmyard manure (FYM), neem oilcake (NOC) and vermicompost (VC). Four nutrient management practices such as N1- FYM (RDN100), N2- FYM (RDN40) + NOC (RDN30) + VC (RDN30), N3- FYM (RDN50) + NOC (RDN25) + VC (RDN25), N4- FYM (RDN60) + NOC (RDN20) + VC (RDN20) were assigned to the sub-plots. Combination of the treatments viz., C3N2, C4N2, C3N3 and C4N3 excelled over the others for grain and protein yields and profitability, but treatment combination C4N2 was the most promising considering the parameters like grain yield (2.10 tha-1), net return (Rs. 36940 ha-1), protein yield (165.75 kg ha-1), calcium yield (7.34 kg ha-1) and iron yield (0.137 kg ha-1). There was significant positive correlation of grain yield with all growth-yield parameters, except test weight, whereas regression analysis indicated 70.86, 85.21 and 73.45% contribution of tillers hill-1, dry matter production and leaf area index at harvest, respectively, to variations in grain yield. The organic finger millet growers should cultivate cv. ‘Kalua’ with application of FYM+NOC+VC @ 4.35+0.34+0.6 t ha-1 for achieving maximum yield and grain quality.

The Impact of Credit Policy Environment on Agricultural Output in Nigeria

The growth of the agriculture sector is a key factor in the survival of the Nigerian economy. However, the production and productivity of this sector have been lower than expected recently. The country is now a net importer of some crops that were previously produced in large quantities. Hence, with the aim to identify factors that influence the sector, the study specifically establishes the relationship between the agricultural sector growth proxy by the agricultural production index and the credit policy variables in Nigeria. The research utilized the flexible autoregressive distributed lag (ARDL) approach to determine the presence of co-integration. The estimated long-run and short-run models demonstrated the best, most efficient, and unbiasedness qualities. The findings revealed that loans from commercial banks and the Agricultural Credit Guarantee Scheme Fund (ACGSF) have a significant positive impact on the agricultural sector's growth in the long run. Conversely, the long-run agricultural growth exhibited a negative relationship with the domestic credit to the private sector and lending interest rate. This finding underscores the importance of boosting commercial bank loans to the agricultural sector and increasing credit volume from the Agricultural Credit Guarantee Scheme Fund. Furthermore, it highlights the necessity of introducing more financial incentives to attract domestic private investments and lowering the lending interest rate on agricultural credit within the country.

ПРИМЕНЕНИЕ МЕТОДА СИМПЛЕКСНЫХ РЕШЕТОК ПРИ МОДЕЛИРОВАНИИ РЕЦЕПТУРЫ ИМБИРНОГО ПЕЧЕНЬЯ

The aim of the study is to optimize the recipe composition of enriched gingerbread cookies (using oatmeal and convection-dried arbutus powder) using a second-order simplex model. The spectral surface of the regression made it possible to determine the dependence of the plastic strength index of products on the percentage of bulk raw materials. An increase in plastic strength, within the studied limits of changes in prescription components by more than 15 %, leads to irreversible rheological changes in the structure of the product. It was established that the content of such mineral elements as potassium, calcium, phosphorus and magnesium increased. The increase in the content of potassium, calcium and phosphorus was insignificant (up to 25 %), magnesium – by 70 %. The developed cookies contain dietary fiber, the share of which was increased by 17 %. Taking into account the fact that the total content of phenolic compounds in 100 g of arbutus powder is 49.8 mg of EGC, its introduction into the recipe (in the amount of 9.5 % by weight of flour) will satisfy the daily need for biologically active food components by 5.8 %. The developed mathematical model made it possible to determine the optimal ratio of prescription components. On the local section of the simplex, the indicator of the plastic strength of the biscuit was evaluated. Using the expected response trace plot, data were obtained for a new type of biscuit, which includes 71.5 % wheat flour, 19 % oatmeal and 9.5 % convection-dried arbutus powder.

Catalytic transesterification of rapeseed oil under supercritical fluid conditions and physical properties of the reaction product

This research examines the transesterification reaction of rapeseed oil with ethanol in the presence of heterogeneous catalysts - Al2O3 and CaO/Al2O3 with 2% mass impregnation of CaO. The experiments were carried out at a molar ratio of ethanol: rapeseed oil of 18:1 (volume ratio ≈ 1:1) at temperatures of 608, 623 K, and a pressure of 20 MPa for up to 30 minutes in a flow-type unit. The state’s selected pressure and temperature parameters correspond to the supercritical fluid conditions. The results are presented for kinematic viscosity (T=313 K, P=0.1 MPa), density (T=288÷323 K, P=0.1 MPa), refractive index (T=298 K, P=0.1 MPa) of the transesterification reaction product. A quantitative assessment of the target product was carried out using chromatographic analysis. We have established the influence of temperature and duration of the reaction process on its efficiency. We present the strength characteristics of the catalysts used before and after the experiments. During attrition, the initial Al2O3 catalyst lost weight by 0.4 ± 0.1%. The mechanical crushing strength along the generatrix was 7.1 ± 0.3 N/mm. The strength of catalysts after carrying out the transesterification reaction under supercritical fluid conditions decreases, on average, by 24-28%. The use of heterogeneous catalysts Al2O3 and CaO/Al2O3 with 2%wt. impregnation of CaO showed an increase in the fatty acid ethyl esters concentration in the transesterification reaction product compared to the reaction carried out without the use of catalysts.

Mare's and Cow's Milk Fortified with Flaxseed Oil Through Freeze-Drying Microencapsulation: Physicochemical and Nutritional Properties.

The microencapsulation via freeze drying of flaxseed oil in cow and mare milk was analyzed. The physicochemical and nutritional properties of the four obtained freeze-dried powder products were comparatively analyzed: microencapsulated and fortified with flaxseed oil cow milk (CMFO) and mare milk (MMFO), as well as pure cow milk (CM) and pure mare milk (MM). The moisture content, water activity, particle size distribution (PSD), loose and tapped bulk densities, flowability, color, and fatty acid profiles of the freeze-dried powders as well as the PSD of reconstituted emulsion droplets were investigated. For both types of milk, the fortified products achieved lower moisture content and water activity, higher loose and tapped bulk densities, better flowability, and lower particle sizes for the reconstituted emulsion droplets. The PSDs of the powders and reconstituted emulsion droplets showed significantly lower levels for the mare milk products than the cow milk products. The atherogenic index (AI) and thrombogenic index (TI) of cow milk products were three and six times higher than those for mare milk products, respectively. In both types of milk, fortified products did not show differences in their AI and TI values, except for the TI for cow milk (where CMFO < CM). The hypercholesterolemia fatty acid index (HcFA), hypocholesterolemic acids (DFAs), hypercholesterolemic acids content (OFA), and n-6/n-3 fatty acid ratio showed greater health benefits from mare milk products. Fortification with flaxseed oil showed increased health-promoting properties in the case of the DFA and OFA parameters (for mare milk) and n-6/n-3 ratio (for cow milk).

Agricultural Transformation and its Contribution to Economic Development in South Asian and African Countries

Agricultural transformation is central to economic development, driving modernization, productivity enhancement, and integration into broader economic systems. This study compares South Asia and Africa, analyzing their distinct trajectories influenced by sustainable practices, policy reforms, and technological advancements. In South Asia, agricultural employment declined sharply, with Bangladesh dropping from 80% in 1973 to 35% in 2023, and India from 70% to 37%. Africa saw a more gradual decline, from 70% to 48% during the same period. Productivity improvements highlight regional progress, with agricultural productivity growth rising in Bangladesh (3.3% to 4.1% by 2023) and Kenya (3.3% to 4.1%), while manufacturing productivity surged in Kenya (6.6%) and India (5.2%). South Asia's growth leverages high-yield crops and market integration from the Green Revolution, while Africa focuses on climate-smart agriculture, diversification, and community-based solutions to address climate vulnerabilities and infrastructure gaps. Both regions emphasize sustainability as a resilience strategy. Using a four-stage paradigm of agricultural transformation, the study underscores the significance of transitioning from subsistence to high-value, technology-driven agriculture for economic diversification and resilience. By analyzing labor productivity, GDP per capita, and crop production indices, the research demonstrates agriculture's critical role in fostering sustainable development and economic growth across both regions.

ATKB-PID: an adaptive control method for micro tension under complex hot rolling conditions

At present, the parameters of the controllers in hot rolling roughing microtension control systems are not adaptively adjustable to variations in working conditions, which compromises both width accuracy and production stability. To address this issue, this paper introduces an ATKB-PID adaptive micro tension control method. This method incorporates a linear attention layer and utilizes a K-Nearest Neighbors (KNN) algorithm to predict the optimal learning rate and inertia coefficient under actual operating conditions. Furthermore, an objective function is tailored to production indices to enhance model performance. Comparative experiments with both established and recently introduced controllers demonstrate that the proposed ATKB-PID method exhibits a smaller steady-state error and quicker adjustment time. The ATKB-PID control method is well-suited for the complex and dynamic microtension control demands in thermal roughing processes, showing promising application potential.

Fruit Quality and Production Parameters of Some Bitter Cherry Cultivars

Bitter cherries (Prunus avium var. sylvestris Ser.) represent a valuable raw material in the traditional Eastern European food industry with high potential within the horticultural chain and circular economy in the context of global food security due to exceptional nutritional properties. The present study was carried out in the period 2022–2024 and had as its main purpose the evaluation of the fruit quality and production indices of some bitter cherry cultivars suitable for the technological norms specific to industrial processing. Five bitter cherry cultivars (C1-Amaris, C2-Amar Maxut, C3-Amar Galata, C4-Silva, C5-Amara) were studied and analyzed in terms of fruit quality—morpho-physiological and organoleptic traits, and physical and chemical parameters—and general productivity—tree vigor, fruiting, and yield indices. The results highlighted a wide variability in the physical characteristics of bitter cherries, with an average weight between 3.3 and 4.9 g and the color of the skin varying from yellow with redness to dark red and blackish. Regarding the chemical attributes, antioxidant activity was relatively higher in fruits with a more intense bitter taste (89.3 μg Trolox·g−1 f.w for C2 and 89.1 μg Trolox·g−1 f.w. for C4 and C5), a fact also found in the content total of polyphenols (with a maximum value of 743.2 mg GAE·100 g−1 f.w at C2). Total soluble solids content had an average value of 20.51°Brix and titratable acidity of 0.85 g malic acid·100 g−1 f.w. The influence of local environmental factors on the productivity of bitter cherry cultivars was highlighted by significant statistical differences (p &lt; 0.05) between cultivars. Thus, the resistance to frost in the full flowering phenophase had an average value of 86.69%, and regarding the resistance to fruit cracking, the highest percentage was found in C1, with 99.79% unaffected fruits. The productivity index per tree had an average value of 0.24 kg per cm2 trunk cross-section area. The physico-chemical properties of the fruits and the productivity of bitter cherry cultivars support the possibility of their efficient use in processing and the food industry, yielding high-quality products with nutraceutical value.

Association between five novel anthropometric indices and erectile dysfunction in US adults from NHANES database

Erectile Dysfunction (ED) is the leading cause of sexual dysfunction affecting hundreds of millions of men worldwide, and has been described as an important public health problem. The association of five novel anthropometrics related to obesity, lipids and glucose with ED remains unclear. To investigate the association of lipid accumulation products index (LAP), triglyceride glucose index (TyG), waist triglyceride index (WTI), weight-adjusted-waist index (WWI) and a body shape index (ABSI) with ED. Cross-sectional data from the NHANES were used. Participants were adults aged 20–85 y from 2001 to 2004. The analysis of logistic regressions, smooth curve fitting, subgroup analyses and generalized addition model were performed to examine the relationship between five novel anthropometric indicators and the prevalence of ED. An overall 1413 adult men were included in the study. After adjusting for confounding factors, the results of multiple regression analysis showed, ED positively correlated with LAP(OR = 1.0031, P < 0.05), TyG(OR = 1.2981, P < 0.05), WTI(OR = 1.4220, P < 0.05), WWI(OR = 1.6043, P < 0.001), and ABSI(OR = 1.6211, P < 0.05). Smoothed curve fitting and subgroup analyses proved the stability of the relationship. This cross-sectional study showed a positive correlation between these five novel anthropometric indicators (LAP, TyG, WTI, WWI, ABSI) and ED. Further studies are needed to explore their association better and the underlying mechanisms.

Lipid Accumulation Product Outperforms BMI and Waist Circumference in Metabolic Disorders.

Background and Objective: Obesity is a global health issue intricately linked to metabolic syndrome (MetS), insulin resistance, and dyslipidemia. Anthropometric indices, particularly those measuring central obesity, have emerged as more reliable predictors of these metabolic disorders than general obesity indices such as body mass index (BMI). However, the relative predictive power of these indices remains debated, particularly across sexes. This study aimed to evaluate the discriminative performance of various anthropometric measures, including lipid accumulation product (LAP), BMI, waist circumference (WC), and visceral adiposity index (VAI), in predicting insulin sensitivity, β-cell function, MetS, and dyslipidemia using National Health and Nutritional Evaluation Survey III (NHANES III) data. Methods: A cross-sectional analysis of 3,706 adults from the NHANES III database was conducted. Anthropometric indices were compared against insulin sensitivity Homeostasis Model Assessment (HOMA)-S, β-cell function (HOMA-B), metabolic syndrome (MetS) status, and dyslipidemia. Receiver-operating characteristic (ROC) curves and linear regression models were used to identify thresholds for predicting metabolic abnormalities. Results: LAP emerged as the most discriminative index across all outcomes, outperforming BMI and WC, particularly in predicting insulin sensitivity and β-cell function in males. In females, BMI was superior in predicting β-cell function. VAI demonstrated the strongest association with dyslipidemia but was less effective in predicting insulin resistance. Conclusion: LAP significantly outperforms conventional anthropometric indices in identifying insulin resistance and MetS, highlighting its potential as a screening tool for cardiometabolic risk. Gender differences in the predictive abilities of these measures suggest that BMI may retain value in assessing β-cell function in females. VAI should be considered when screening for dyslipidemia but is less effective for insulin resistance.

Эффективность ЕАЭС как гарантия стабильного развития региона

The work examines issues related to the effectiveness of the functioning of the Euro-Asian Economic Union (EAEU), consisting of five countries: the Russian Federation, Kazakhstan, Belarus, Armenia and Kyrgyzstan. An assessment was made of GDP production indicators and product production indices, both for the EAEU as a whole and among its participants. The dynamics of indicators of both the total permanently resident population of the union and residents of rural areas was studied. An analysis of the values of the indicators of the share of agricultural products in the total volume of all produced products of the EAEU was carried out.

Biosecurity Practices for Reducing Antimicrobial Use in Commercial Broiler Farms in Korea

Farm biosecurity is valuable for reducing the indiscriminate use of antimicrobials. However, its relationship with antimicrobial usage can be difficult to assess because of multiple factors. This study evaluated the impact of biosecurity practices on productivity, frequency of antimicrobial use, and development of antimicrobial resistance. Among factors related to biosecurity, mortality rate <2% within one week of age, survival rate >98%, and production index >350 in farms in which: bedding was not reused or only reused once, regular advice and biosecurity training was provided by poultry veterinarians, distinctions between clean and dirty areas were strictly enforced at all times, workers used farm biosecurity manuals, or disinfection guidelines were fully implemented, including cleaning before introducing new flocks and daily disinfection throughout growth, were significantly higher than those in farms without these measures (p < 0.05). The absence of biosecurity practices increased antimicrobial use to one (25.7%), two (39.2%), and three (25.7%) times (p < 0.05). In farms that implemented biosecurity practices, the antimicrobial administration was significantly increased to two times (44.2%) (p < 0.05), with only 17.4% of farms using antimicrobials three times. The prevalence of environmental Escherichia coli resistant to multiple cephalosporins and chloramphenicol, which are not used on broiler farms, was significantly reduced by biosecurity practices (p < 0.05). Our findings indicate that improved biosecurity practices decrease antimicrobial use, decrease the incidence of antimicrobial-resistant bacteria, and help to eliminate resistant bacteria in farm environments.

Industrial Production vs. Goods GDP: Two Sides of the Same Coin?

Since the early 2000s, there has been a growing divergence between the index of industrial production (IP) and the goods component of GDP—hereafter, goods GDP—breaking the close correlation the two series had maintained in earlier decades (figure 1). This note revisits the factors behind this divergence and provides a novel quantification of their role.

The relationship between business competition and welfare in Indonesia.

This research freshly investigates the effect of business competition on national welfare in Indonesia. This research uses business competition index data obtained from the Indonesia Competition Commission (KPPU) and welfare indicators data collected from the Indonesian Bureau of Central Statistics (BPS) at the economic sectoral and provincial levels for the period 2018-2020. The relationship between business competition and welfare is estimated using pooled regression model combining year, economic sector, and province. This research also uses business competition index applying both same weights for all dimensions of competition and the weights derived from principal component analysis. This research finds that business competition has a positive effect on welfare as represented by gross regional domestic product, regional productivity, productivity growth, wages, and human development index. Furthermore, the regions with high scores on the competition index mostly come from Java Island. Therefore, Indonesian government must encourage the mainstreaming of business competition in all provinces in Indonesia.

Association of CVAI, LAP and SMI with risk of haematological toxicity after immunochemotherapy in patients with DLBCL: a retrospective study.

The occurrence of adverse events after immunochemotherapy in patients with diffuse large B-cell lymphoma (DLBCL) frequently affects the course of chemotherapy, leading to a further decline in quality of life and survival. The primary objective of this study was to investigate the association between Chinese visceral adiposity index (CVAI), lipid accumulation product (LAP) index and skeletal muscle mass index (SMI) at initial diagnosis and the risk of haematological toxicity following immunochemotherapy in patients with DLBCL. Retrospective, single-centre study. CVAI, LAP and SMI were calculated by combining clinical data of the patients. This study included 213 patients, of whom 117 (55%) patients experienced grades 3-4 haematological toxicity after immunochemotherapy. Participants were divided into four groups (Q1, Q2, Q3, Q4) based on the quartiles of CVAI, LAP and SMI. In the fully adjusted model, the risk of grades 3-4 haematological toxicity in group with the highest CVAI and LAP was reduced by 75.1% (OR: 0.249, 95% CI: 0.102-0.606, p = 0.002) and by 77.3% (OR: 0.227, 95% CI: 0.095-0.542, p = 0.001) compared to the group with the lowest CVAI and LAP. For SMI, the risk of grades 3-4 haematological toxicities in the group with the highest SMI was reduced by 62.9% compared with the lowest SMI group in the unadjusted model. The multivariable-adjusted restricted cubic spline curves and subgroup interaction analyses further confirmed the robustness of these findings. The results indicate that DLBCL patients with relatively high CVAI, LAP and SMI at initial diagnosis have a lower risk of severe haematological toxicity following chemotherapy. Therefore, CVAI, LAP and SMI at initial diagnosis are reliable and effective biomarkers for predicting severe haematological toxicity after immunochemotherapy in DLBCL patients. This is a retrospective study, and no registration on ClinicalTrials.gov.

INFLUENCE OF MEDICINAL PLANTS AND VITAMIN E ON PRODUCTIVE PERFORMANCE AND SOME PHYSIOLOGICAL PARAMETERS OF BROILER CHICKENS UNDER HEAT STRESS

This study was aimed to evaluate the influence of adding dietary three medicinal plants and vitamin E on productive performance, serum physiological parameters, immunity and antioxidant status of broiler chickens under heat stress (34 - 38) C° for 35 days. A total of 600 Ross one day old broiler chicks were distributed randomly into eight treatments with five replicates 15 birds per each replicate as follows: T1: broiler were fed standard ration (negative control); T2: 50 mg vitamin E /kg ration (positive control); T3: 5g Dill powder /kg ration; T4: 10g Dill powder /kg ration; T5: 5g Adiantum powder /kg ration; T6: 10g Adiantum powder /kg ration; T7: 5g Crataegus powder /kg ration and T8: 10g Crataegus powder /kg ration. Live body weight, feed intake, feed conversion ratio and mortality rate were measured at weekly intervals. There was a significant effect of medicinal plants on live body weight at 35 day. However, non-significant difference was noticed on feed intake, significant differences on feed conversion ratio, mortality and livability%. Regarding male chickens, T3 treatment had significantly higher carcass yield as well as each of T3 male and T4 female had higher dressing percentage. Furthermore, higher production index was found in T4 while, high value of economic figure was shown in T5 as well as significant effect on serum thyroid hormone T3,T4, corticosterone hormone and enhanced total antioxidant capacity and stable malondialdehyde all helped to reduce oxidative stress as well as boost antibody titers of ND and IBD compared with T1. It can be concluded that the supplementation of medicinal plants to broiler´s diet had a beneficial effect on most of broiler performance, improving immunity, resistance characteristics and oxidative stress particularly in T4 (Dill10g/kg) under heat stress.
