High selenium diet attenuates pressure overload-induced cardiopulmonary oxidative stress, inflammation, and heart failure

Selenium (Se) deficiency is associated with the development of Keshan disease, a cardiomyopathy associated with massive cardiac immune cell infiltration that can lead to heart failure (HF). The purpose of this study was to determine whether high Se diet can attenuate systolic overload-induced cardiopulmonary inflammation and HF. Briefly, transverse aortic constriction (TAC)-induced cardiopulmonary oxidative stress, inflammation, left ventricular (LV) dysfunction, and pulmonary remodeling were determined in male mice fed with either high Se diet or normal Se diet. High Se diet had no detectable effect on LV structure and function in mice under control conditions, but high Se diet significantly protected mice from TAC-induced LV hypertrophy, dysfunction, increase of lung weight, and right ventricular hypertrophy. As compared with mice treated with normal Se diet, high Se diet also reduced TAC-induced LV cardiomyocyte hypertrophy, fibrosis, leukocyte infiltration, pulmonary inflammation, pulmonary fibrosis, and pulmonary micro-vessel muscularization. In addition, high Se diet significantly ameliorated TAC-induced accumulation and activation of pulmonary F4/80+ macrophages, and activation of dendritic cells. Interestingly, high Se diet also significantly attenuated TAC-induced activation of pulmonary CD4+ and CD8+ T cells. Moreover, we found that TAC caused a significant increase in cardiac and pulmonary ROS production, increases of 4-hydroxynonenal (4-HNE) and 3-nitrotyrosine (3-NT), as well as a compensatory increases of LV glutathione peroxidase 1 (GPX1) and 4 (GPX4) in mice fed with normal Se diet. Above changes were diminished in mice fed with high Se diet. Collectively, these data demonstrated that high Se diet significantly attenuated systolic pressure overload-induced cardiac oxidative stress, inflammation, HF development, and consequent pulmonary inflammation and remodeling.

Divergent Immediate and Delayed Effects of Juvenile Exposure to Doxorubicin on the Thymus in C57BL/6 Mice.

The understanding of alterations within the immune system following doxorubicin (DOX) chemotherapy, and subsequent restoration, in childhood cancer survivors remains limited. This investigation endeavors to elucidate the immediate and delayed changes in thymic immune cell populations and their phenotypes in response to clinically relevant low doses of DOX in a juvenile mouse model. Male mice underwent a regimen of repeated low-dose DOX intraperitoneal injections at 4 mg/kg/week for three consecutive weeks. One week after the last dose of DOX, a subset of mice was euthanized to assess the immediate effects of DOX administration. A second subset of mice was euthanized five weeks after the last DOX dose to evaluate the delayed effects. Thymic samples were collected for multiparameter flow cytometry analysis to evaluate alterations in immune cell composition and phenotype. Additionally, quantitative real-time polymerase chain reaction (qRT-PCR) was employed to measure gene expression of- cytokines and senescence markers. One week following DOX administration, DOX treatment resulted in significant decline in thymus weight, with notable alterations in immune cell subpopulations. Reduced frequencies of mature CD3+CD4+ and CD3+CD8+ T cells were observed, along with changes in proliferation and exhaustion markers. Gene expression analysis revealed upregulation of Foxn, Pax1, Ifnγ, and Il7 alongside decreased Il6 and Il17 expression. Furthermore, Cdkn1a (p21Cip1) expression was elevated, suggesting immunosenescence. Five weeks following DOX administration, delayed effects of DOX treatment manifested in rebound increase in thymus weight and altered frequencies of CD4+ and CD8+ T cell subsets, with distinct patterns of proliferation and exhaustion observed. Notably, central memory CD4+ T cells exhibited significant decrease in frequency, while naive and effector memory CD4+ T cells showed reduced proliferation (Ki67+) and PD1 expression. Similar trends were observed in CD8+ T cell subsets, indicating selective effects of DOX on T cell differentiation and function. Although expression of thymus-related genes was normalized, p21Cip1 gene expression remained elevated. DOX treatment elicits a multifaceted influence on immune cell subsets and thymic weight. Immediate effects included thymic atrophy and reductions in mature T cell populations, while delayed effects showed rebound thymic hyperplasia and selective changes in CD4+ and CD8+ T cell subsets. Notably, both central memory and effector memory T cells exhibited reduced proliferation and exhaustion, suggesting unique impacts of DOX on immune cell function. The enduring elevation in p21Cip1 gene expression 5 weeks after DOX treatment suggests an immunosenescent phenotype. These observations collectively illuminate the formidable task of preserving immune competence and overall well-being in childhood cancer survivors subjected to DOX therapy.

Անուղղակի ծախսումների մասին տեղեկատվության կառավարման մեխանիզմների կատարելագործումը շինմոնտաժային աշխատանքներ կատարող կազմակերպություններում / Improving indirect cost allocation in construction organisations

The issue of the indirect cost allocation is not new, but it is becoming more relevant due to the increase in the relative weight of indirect cost in the production cost in organizations. This is due to automation of production processes and other reasons. Often, a single basis is used for the indirect cost allocation in organizations, but the choice of a single allocation basis for all resources and calculation objects cannot accurately reflect all causal relationships, that is why the process is conditional. Based on the professional literature and in accordance with the characteristics of the studied organizations, an indirect cost grouping was made for the organizations performing construction works and an approach of costing based on Activity-Based Costing was proposed. According to the author, the proposed approach can improve the financial information management mechanisms, and especially information about indirect cost, therefore also cost, and other indicators calculated based on it, in organizations.

Mechanisms of adaptation of the hypothalamic-pituitary-adrenal axis in male mice under chronic social defeat stress

The hypothalamic-pituitary-adrenal axis (HPA) plays an important role in the mechanisms of adaptation to chronic stress. A model of chronic social defeat stress (CSDS), based on the experience of defeat in daily agonistic interactions, causes the development of a depressive-like state in mice, which is often accompanied by an increase in blood corticosterone levels. In this work, we assessed what changes occur in the central (hypothalamus) and peripheral (adrenal glands) parts of the HPA axis under the influence of chronic social stress, which can affect the regulation of corticosterone synthesis and its level in the blood. The experience of chronic social stress causes an increase in the relative weight of the adrenal glands, an increase in the expression level of Crh gene in the hypothalamus and the expression of the genes for the corticosterone synthesis enzymes Star, Cyp11a1, Cyp11b1 in the adrenal glands. At the same time, in the hypothalamus the expression of Fkbp5 and Nr3c1 decreases and the expression of Crhbp increases, and in the adrenal glands the expression of the Mc2r and Hsd11b1 genes decreases, which is ultimately aimed at reducing the amount of corticosterone secreted by the adrenal glands, and thus limiting the glucocorticoid response. Thus, chronic stress leads to an imbalance of the activating and stabilizing mechanisms of HPA axis regulation and a possible inadequate response to additional stress stimuli.

Systematic review of randomised controlled clinical trials examining effectiveness of contingent financial rewards for smoking cessation during pregnancy: intention-to-treat and causal effects on birthweight.

Objective: To examine birth weight change caused by adding financial rewards for smoking cessation compared to no rewards for pregnant women. To estimate the average expected birth weight change for those who quit because of rewards. This study updates a previous systematic review and refocuses the outcome from smoking cessation to birth weight.Eligibility Criteria: Trials with an experimental design allowing treatment effects to be attributed to rewards were included. Trials involving non-pregnant participants, or with no report of magnitude, treatment duration, timing or where most rewards were contingent on another behaviour (e.g., treatment attendance) were excluded.Information sources: Medline, PsycInfo, Embase, Cochrane (Central Register of Controlled Trials, Tobacco Addiction Group Specialised Register and Database of Systematic Reviews), and PubMed searched to 5th December 2023.Risk of bias: Risk of bias and certainty of evidence used Cochrane 'Risk of bias 2' and GRADE assessments.Synthesis of results: Primary analysis estimated Intention-To-Treat (ITT) mean birthweight difference when randomised to offer of rewards versus control. Within-trial estimates and standard errors were derived from mean, standard deviation, and sample size data provided, or from publications. Pooled ITT estimates used common (fixed) and random effects models. Secondary analyses used trial team supplied data to derive Complier Average Causal Effect (CACE) estimate of smoking cessation on birth weight, and a standard error. Estimates were pooled using common and random effects models. Similar analyses were applied to low birth weight (<2500g), birth weight for gestational age z-scores, and small for gestational age (<10 th percentile). Included studies: Primary analysis included 8 trials (2351 participants) from the UK (2 trials, 1475 participants); France (1 trial, 407 participants), and the US (6 trials, 469 participants). Secondary analysis included 7 trials as data retrieval from one US trial (51 participants) was not possible.Synthesis of results: Primary ITT analysis (2351 participants) estimated a mean 46.3g (95% CI: 0.0 to 92.6) birth weight increase when offered financial rewards for smoking cessation. Secondary CACE analysis (2239 participants) estimated a mean 206.0g (95% CI: -69.1 to 481.1) increase for smokers who quit because of rewards. There was no effect on low birth weight (<2500g), or birth weight adjusted for gestational age, though less babies were born small for gestational age, particularly if cessation was because of rewards (CACE risk difference -17.7%; 95% CI: -34.9% to -0.4%). Limitation of evidence: Sample size led to imprecision - maximum 2351 participants. A single trial of 3712 participants would give 80% power at 5% significance to show a 46g increase from 3.1kg to 3.146kg with 0.5kg standard deviation in both groups. Consistency - trials where smoking cessation increased (7 of 8) all showed a mean birth weight increase. In one trial smoking cessation fell as did birth weight. Bias is unlikely as 3 of 4 trials with no birth weight data showed increased cessation consistent with higher mean birth weight. Interpretation: Trials of contingent financial rewards for smoking cessation have previously been shown to more than double pregnancy quit rates. We have uncovered a significant (46g) population level increase in mean birth weight, driven by a clinically important mean increase (206g) for those who quit because of financial rewards associated with a reduction in Small for Gestational Age births.

Therapeutic Effects, Side Effects, and Adverse Effects of Neuropsychiatric Drugs in the Context of Treating Cancer-Related Anorexia With Olanzapine and Mirtazapine.

Drugs have actions that may be classified as therapeutic effects and side effects; side effects are actions that do not contribute to therapeutic benefit. Some side effects are neutral; others, experienced as undesirable or unpleasant, are recorded as adverse effects. Some drug actions are therapeutic for some disorders and adverse for others; or therapeutic during acute illness and adverse during maintenance treatment. As an example, anticholinergic action may be adverse when a tricyclic antidepressant is used to treat depression but therapeutic when the drug is used to treat irritable bowel syndrome with diarrhea. In clinical practice, side or adverse effects of a drug may be leveraged to manage troublesome symptoms. As an example, the sedative effect of a low dose of trazodone may be useful for some patients with insomnia. With this background, studies have examined whether the increase in appetite and weight associated with olanzapine and mirtazapine may be effective against anorexia and cachexia associated with cancer and cancer chemotherapy. The subject is important because cachexia may be present in 30%-50% of patients with cancer (with higher prevalence in patients with more advanced cancer) and because the presence of cachexia is associated with a higher risk of disease progression and mortality. Many randomized controlled trials (RCTs) have examined pharmacologic interventions such as progestins, corticosteroids, anamorelin, and medical cannabis for cancer related cachexia; most results have been disappointing. A recent RCT found that olanzapine (2.5 mg/d for 12 weeks) improved appetite, weight, other nutritional parameters, and quality of life in patients with locally advanced or metastatic cancer treated with chemotherapy. Another RCT, however, found that mirtazapine (30 mg/d for 8 weeks) brought no nutritional or anthropometric gain in patients with cancer and anorexia. It is concluded that olanzapine but not mirtazapine merits further investigation in patients with cancer who have anorexia and cachexia.

Duration, not timing during the photoperiod, of far-red application determines the yield increase in tomato

Supplementary far-red light may increase fruit yield in greenhouse tomato cultivation. Apart from end-of-day applications, research has focussed on the effects of far-red light during the entire photoperiod, while few studies focused on the timing of far-red application. In this study, we assessed the impact of timing and duration of far-red application on fruit yield and quality in a high-wire tomato crop. Two commercial tomato cultivars were grown under 226 μmol m−2 s−1 of red and white supplementary LED lighting. Far-red light (63 μmol m−2 s−1) was additionally supplied during either the first or the second half of the photoperiod. These treatments were compared to a negative control, where no far-red light was supplied, and a positive control, where far-red light was supplied during the whole photoperiod. A yield component analysis was conducted to identify the parameters responsible for changes in fruit yield. We determined that fruit yield, total fruit dry weight and fruit production per unit of supplementary PAR light (400–700 nm) increased linearly with the duration of far-red application. Fruit yield was increased to a similar extent whether far-red was supplemented in the first or in the second half of the photoperiod. While different light treatments included 0, 14, or 28 % far-red in their cumulative supplementary photon flux density, there were no significant differences in their fruit production per unit of supplementary radiation (400–800 nm). Supplementary far-red increased fruit dry weight per unit of cultivation area by 23 % to 25 % as a result of increasing both plant dry weight (10 % to 12 %) and dry weight partitioning to the fruits (10 % to 14 %). The increase in fruit yield was less than the corresponding increase in total fruit dry weight due to a simultaneous increase in fruit dry matter content. Total soluble solids and pH of the fruits were hardly affected by far-red application. We concluded that supplementary far-red increased tomato fruit yield without compromising fruit quality, with this increase being determined by the duration of far-red application, not by its timing during the photoperiod.

Dual Phytochemical/Activity-Guided Optimal Preparation and Bioactive Material Basis of Orthosiphon Stamineus Benth. (Shen Tea) against Nonalcoholic Fatty Liver Disease.

Orthosiphon stamineus Benth. (OSB) is a popular plant used for making "Shen tea" or "Java tea". It has been demonstrated with antioxidant, anti-inflammatory, and hepatoprotective activities. However, its potential beneficial effects and bioactive material basis for nonalcoholic fatty liver disease (NAFLD) has not been convincingly studied. In the present work, we conducted dual phytochemical/activity-guided extraction optimization and component fractionation of OSB, and evaluated its beneficial effects on NAFLD. Flavonoids and polyphenols (caffeic acid/protocatechuic acid derivatives) were determined as the dominant phytochemicals in OSB. The extraction process for these phytochemicals was optimized by using response surface methodology. Noticeably, flavonoids showed a stronger correlation with the antioxidant activities of OSB than polyphenols. Likewise, the flavonoid-rich fraction of OSB exerted antioxidant activities stronger than those of other fractions. As expected, in vitro and in vivo studies demonstrated that the flavonoid-rich fraction effectively attenuated weight increase, improved lipid metabolism, alleviated hepatic steatosis, and reversed hepatic inflammation. Importantly, this fraction showed equivalent beneficial effects to the total extract of OSB, suggesting that flavonoids were the main bioactive constituents of OSB. The action mechanism was indicated as direct antioxidant effect through chemical interaction with free radicals and indirect mitochondria-mediated antioxidant defense. Our research offers bioactive substances for further exploitation and expands the potential application of OSB.

Combined analysis of gut microbiota and metabolomics in high-fat model mice fed with Chlorella pyrenoidosa peptides

Chlorella pyrenoidosa peptides (SISISVAGGGR, T1) can effectively alleviate obesity and related metabolic disorders in high-fat mice. However, their lipid-lowering mechanism is still unclear. This research endeavor sought to delve into the potential mediators of T1 anti-obesity in high-fat mice through macrogenomics analyses combined with untargeted metabolomics analyses. The results showed that T1 alleviated HFD-induced increases in body weight, epididymal fat weight, TG, LDL, AST, TNF-α, and IL-1β levels, and increased HDL level. Moreover, T1 reversed the HFD-induced gut microbiota dysbiosis. Specifically, T1 resulted in a massive proliferation of Bacteroides, Parabacteroides, and Alistipes, as well as increased levels of metabolites such as DL-arginine, N-stearoyl GABA, and decreased levels of 7α,24(S)-dihydroxy-4-cholesten-3-one, and hexadecanedioic acid. Correlation analysis showed that T1 alleviated HFD-induced obesity metabolic syndrome and associated inflammation by modulating specific gut microbiota and related metabolites. This provides new ideas for the treatment of diet-induced obesity and related metabolic disorders.

Comparative evaluation of adverse drug reactions for tenofovir alafenamide and tenofovir disoproxil fumarate using the FAERS Database: a disproportionality analysis.

Tenofovir alafenamide (TAF) and tenofovir disoproxil fumarate (TDF) are widely used nucleoside reverse transcriptase inhibitors (NRTIs), necessitating a thorough understanding of their safety profiles to ensure optimal patient care and treatment adherence. We employed statistical methods including the reporting odds ratio (ROR), proportional reporting ratio (PRR), Bayesian Confidence Propagation Neural Network (BCPNN), and Multi-Item Gamma Poisson Shrinker (MGPS) to compare and evaluate the safety profiles of these NRTIs. TAF was significantly associated with weight increase (ROR: 6.43; 95% CI: 5.93-6.96) and specific psychiatric disorders. TDF showed a notable signal for renal disorders and product-related issues, including product dose omission (ROR: 3.53; 95% CI: 3.22-3.87). Additionally, the study highlighted differences in safety signals related to pregnancy outcomes, with TAF having a higher ROR for maternal exposure (ROR: 7.83; 95% CI: 7.06-8.69) and TDF for fetal exposure (ROR: 4.51; 95% CI: 3.93-5.18), underscoring the need for cautious use in pregnant women. The comparative analysis also identified signals for osteonecrosis (ROR: 108.81; 95% CI: 106.25-111.43) and bone loss (ROR: 714; 95% CI: 685.49-743.68) for TAF and TDF, respectively, highlighting the importance of bone health considerations in treatment plans. These findings underscore the importance of personalized antiviral therapy and patient safety.

Antimicrobial characteristics of endophytic Aspergillus terreus and acute oral toxicity analysis

BackgroundEndophytic fungi produce biologically robust metabolites suitable for diverse applications, which support the increasing exploration of these fungi. The study aimed to investigate the in vitro antimicrobial properties of the metabolites of endophytic fungus Aspergillus terreus which isolated from the leaves of Psidium guajava plants while the acute oral toxicity was assessed in vivo. ResultsA. terreus (OR125572) was successfully isolated for the first time from P. guajava. The ethyl acetate extract of A. terreus exhibited antibactericidal effects against Enterobacter aerogenes with a minimum inhibitory concentration of 18.75 mg/ml in contrast to 75.00 ± 0.0, 37.50, and 37.50 mg/ml, respectively against Staphylococcus aureus, Escherichia coli, and Bacillus sphaericus were 75.00 ± 0.0, 37.50, and 37.50 mg/ml, respectively. Analysis of the crude extract obtained from A. terreus by GC-MS revealed a total of 32 distinct compounds. The major components included 1,2-benzenedicarboxylic acid, di-iso-octyl ester; hexyl oxecan-2-one and phenol. The acute oral toxicity study found no symptoms of toxicity and no mortality until the 14th d, suggesting that the LD50 value of A. terreus extract might exceed 1 ml/kg. The group receiving 0.5 ml/kg of A. terreus extract experienced a 42.9% increase in body weight, while administration of varying dosages resulted in a significant reduction in MCV levels. There was also a significant increase in the proportion of monocytes across all treated groups. ConclusionsThe study demonstrated the potential of A. terreus as a source of antimicrobial and other bioactive compounds, with relatively low acute toxicity.How to cite: Shehabeldine AM, Abdelaziz AM, Abdel-Maksoud MA, et al.

Capsaicin Reduces Obesity by Reducing Chronic Low-Grade Inflammation.

Chronic low-grade inflammation (CLGI) is associated with obesity and is one of its pathogenetic mechanisms. Lipopolysaccharide (LPS), a component of Gram-negative bacterial cell walls, is the principal cause of CLGI. Studies have found that capsaicin significantly reduces the relative abundance of LPS-producing bacteria. In the present study, TRPV1-knockout (TRPV1-/-) C57BL/6J mice and the intestinal epithelial cell line Caco-2 (TRPV1-/-) were used as models to determine the effect of capsaicin on CLGI and elucidate the mechanism by which it mediates weight loss in vivo and in vitro. We found that the intragastric administration of capsaicin significantly blunted increases in body weight, food intake, blood lipid, and blood glucose in TRPV1-/- mice fed a high-fat diet, suggesting an anti-obesity effect of capsaicin. Capsaicin reduced LPS levels in the intestine by reducing the relative abundance of Proteobacteria such as Helicobacter, Desulfovibrio, and Sutterella. Toll-like receptor 4 (TLR4) levels decreased following decreases in LPS levels. Then, the local inflammation of the intestine was reduced by reducing the expression of tumor necrosis factor (TNF)-α and interleukin (IL)-6 mediated by TLR4. Attenuating local intestinal inflammation led to the increased expression of tight junction proteins zonula occludens 1 (ZO-1) and occludin and the restoration of the intestinal barrier function. Capsaicin increased the expression of ZO-1 and occludin at the transcriptional and translational levels, thereby increasing trans-endothelial electrical resistance and restoring intestinal barrier function. The restoration of intestinal barrier function decreases intestinal permeability, which reduces the concentration of LPS entering the circulation, and reduced endotoxemia leads to decreased serum concentrations of inflammatory cytokines such as TNF-α and IL-6, thereby attenuating CLGI. This study sheds light on the anti-obesity effect of capsaicin and its mechanism by reducing CLGI, increasing our understanding of the anti-obesity effects of capsaicin. It has been confirmed that capsaicin can stimulate the expression of intestinal transmembrane protein ZO-1 and cytoplasmic protein occludin, increase the trans-epithelial electrical resistance value, and repair intestinal barrier function.

Effects of a Specialized Oral Nutritional Supplement with Dietary Counseling on Nutritional Outcomes in Community-Dwelling Older Adults at Risk of Malnutrition: A Randomized Controlled Trial.

This study investigated the effects of oral nutritional supplements (ONSs) along with dietary counseling (DC) in community-dwelling older adults at risk of malnutrition. In this randomized controlled trial, 196 older adults who were at risk of malnutrition, as identified by the Malnutrition Universal Screening Tool (MUST) were randomly assigned to receive ONSs twice daily with DC (intervention) or DC-only (control) for 60 days. Primary outcome was change in body weight from baseline to day 60. Nutritional status, energy, and macronutrient intakes were measured. A significant larger weight gain was observed in the intervention compared to the control from baseline to day 60 (1.50 ± 0.22 kg, p < 0.0001). The intervention group also showed a significantly greater increase in weight at day 30 (p < 0.0001). Intakes of energy and macronutrients were significantly higher in the intervention group compared to the control group at both days 30 and 60 (all p < 0.0001). The odds of achieving better nutritional status were significantly higher in the intervention group than in the control group (OR:3.9, 95% CI: 1.9, 8.2, p = 0.0001). ONS supplementation combined with DC significantly improved body weight and nutritional outcomes in community-dwelling older adults at risk of malnutrition.

The association between preterm birth and the supplementation with vitamin D and calcium during pregnancy

Although vitamin D (VD) supplementation or calcium supplementation during pregnancy has become publicly accepted and part of health care behavior, the effect of co-supplementation on preterm birth remains unclear. To explore whether the supplementation with vitamin D and calcium during pregnancy is associated with preterm birth. The study was the baseline survey from the birth cohort in Jinan, which was built at one month after the baby birth. Preterm birth and monthly VD and calcium supplementation during pregnancy were obtained by the questionnaire. The logistic model was conducted to exam the association. The distributed lag nonlinear model was applied to explore the critical window for the supplements. Preterm birth occurred in 4.4 % (285/6501) of the study subjects with single live births and the rates were 39.7% and 82.6% for single VD supplementation or calcium supplementation in pregnancy. The adjusted OR (95% CI) for preterm birth was 1.428 (1.115-1.829) related to VD and 0.883 (0.652-1.216) related to calcium. It is interesting to note that the increased risk of preterm birth with VD supplementation during pregnancy was only seen in pregnant women who supplemented with calcium (OR was 1.600) and had a significant increase in preterm birth weight (P=0.040). Besides, supplementation VD with calcium during pregnancy from the 3rd to 6th month during pregnancy was associated with preterm birth (OR3rd=1.216, 95% CI: 1.119-1.320; OR4th=1.275, 95% CI: 1.152-1.411; OR5th=1.279, 95% CI: 1.130-1.446; OR6th=1.208, 95% CI: 1.076-1.356). Moreover, birth weight mediated 10.8% of the total effect of supplementation on preterm birth. Women who supplemented with VD among taking calcium during pregnancy were more likely to experience preterm birth, and birth weight partly mediates the effect. The critical window for association between supplements and preterm birth may be from the 3rd to 6th weeks of pregnancy.

The Value of Hay Provided in Different Phases of Alfalfa Development

This article presents the results of research on the study of the chemical composition, digestibility, energy value of hay from alfalfa-rump grass mixture, harvested by the method of active aeration in different phases of alfalfa development, the productive properties of hay of different quality when fattening bulls in the dry steppe zone of the Nakhchivan. The amount of digestible energy decreased as the plants aged. Its highest concentration (12.8 MJ per 1 kg of dry matter) was observed during the budding phase. Then a decrease in this indicator was recorded by 0.8 MJ in the flowering phase and by 1.5 MJ during seed formation. The same pattern was noted for the content of metabolic energy in hay. Thus, the greatest amount was in hay harvested during the budding phase — 8.3 MJ per 1 kg. During the flowering phase, the amount of metabolic energy in 1 kg of hay decreased by 0.4 MJ, and seed formation by 1.2. Thus, the coefficient of digestibility of dry matter was higher than similar indicators during later harvesting by 4.01 and 7.05%, respectively. Crude protein in early harvested hay was digested better than in hay prepared in the phase of flowering and the beginning of alfalfa seed formation, by 11.83 and 18.03%, crude fiber — by 3.0-3.26%. A significant difference was also noted in digestion of raw fat. The digestibility of this substance decreased noticeably as plants aged. A decrease in the digestibility of nitrogen-free extractives was observed in hay during the seed formation phase. Calculations carried out on the basis of actual material obtained in the experiment show that when feeding hay harvested at the beginning of alfalfa budding, the yield of bull calves (increase in live weight) per 1 hectare of harvested area increases by 27.6% compared with harvesting in the flowering phase and 3.1 times in the seed formation phase.

Literature Review: Pengaruh PMT Pangan Lokal Pada Balita sebagai Upaya Pencegahan Stunting

The high prevalence of stunting is a global problem of great concern. Efforts to reduce stunting are to provide additional food to children locally to improve their nutritional status. The purpose of making this literature review is to find out the effectiveness, influence, success of the program, and efforts to provide additional food to stunted toddlers. This literature review uses several sources, namely Sinta accredited journals related to supplementary feeding which can be searched using google scholar and the SINTA database. Based on the findings of 16 studies of supplementary feeding made from local food in stunted toddlers, there was an increase in body weight and height when supplementary feeding was given for at least 30 days. Tempeh, rebon shrimp, and moringa are local foods that are easily available and relatively cheap. They also have high nutritional value. After being given tempe, rebon shrimp, and moringa, as local foods, the toddler's height increased significantly.

Investigating metabolic syndrome markers and body mass index changes in patients with acne vulgaris treated with isotretinoin: A prospective study.

Acne vulgaris is a common inflammatory skin disease that occurs during puberty, affecting approximately 85% of young adults and may persist into adulthood. The pathophysiology of acne is multifactorial, involving hormonal, inflammatory, and immune mechanisms. Isotretinoin is widely used for treating severe cystic acne or recurrent acne. This medication is considered a pharmacological option that significantly reduces sebum secretion, leading to a reduction in the size of sebaceous glands. It also induces a lack of differentiation in sebaceous cysts, resulting in a decrease in lipid accumulation. This research is a prospective study. Patient contact details were obtained directly from those visiting the dermatology clinic, and they were monitored for a duration of 3 months. Essential data was gathered through patient examinations and inquiries at the clinic, including the prescription of tests prior to initiating isotretinoin treatment. Furthermore, follow-up tests and examinations were performed within the initial and third months post-treatment commencement. Sixty-two patients participated in the study, selected through non-probability (convenience) sampling. The therapeutic dose taken by patients was 20 mg of isotretinoin daily (n = 49) or every other day (n = 13). Among the participants, six patients experienced a decrease of 3 units or more in HDL levels, while 16 patients saw an increase of 3 units or more in LDL levels, 3 months after beginning the treatment. Additionally, the triglyceride (TG) levels increased by 9 units or more in six individuals, and the blood sugar (BS) levels increased by 5 units or more in nine individuals, 3 months after treatment initiation. Moreover, one person's waist circumference increased by 1.5 cm 3 months after treatment began. The average weight of the individuals at the end of the treatment rose from 60.74 kg to 61.12 kg. However, this weight increase was not statistically significant. (p > 0.05). In general, the results of our study show that the use of oral isotretinoin as a treatment option for the management of acne vulgaris can be effective when administered at the correct dosage, offering a safe and low-complication option.

Cooperation dynamics in multi-issue repeated social dilemma games with correlated strategy.

In the real world, individuals are often involved in collaboration on multiple issues, and these issues may interact with each other. Given the complexity of the interaction, we establish a multi-issue repeated game model, in which individuals participate in multiple social dilemma games simultaneously and repeatedly, and strategies in different issue games are correlated and reactive. We explore the cooperation dynamics of strategies in the population from a multiobjective perspective, in which an individual's preference for each issue is described by a weight vector, and heterogeneous preferences of individuals in the population are also considered. Through simulations on two-issue games, we find that compared to the uncorrelated case, the correlated strategy can significantly promote cooperation in both games regardless of which issue players prefer. Under the condition of homogeneous preference, an increase in the payoff weight of a given issue decreases the level of cooperation in that issue, and the optimal condition to sustain cooperation to the maximum extent is when the payoff weights of all issues are equal. Moreover, under the condition of heterogeneous preference, there exists an optimal proportion of players with different preferences under which the cooperation rate can reach its highest level in the population. This work highlights individual trade-offs on different issues when engaging in multiple games simultaneously and further enriches the research of evolutionary games from a multiobjective and correlated strategy perspective.

Bayesian analysis of the effects of some identified risk factors of systolic pressure among pregnant women in Ogbomoso, Oyo State

Unhealthy condition during pregnancy is a function of abnormal Systolic Blood Pressure (SBP). Therefore, this becomes a threat to women and health policy makers on how to reduce the consequence of high SBP. To overcome this challenge, appropriate model must be specified to capture some identified clinical-genetic factors for SBP in pregnant women when the informative prior to these factors is not sufficiently available. The aim of the study is to develop a Bayesian Logit (BLM) to calculate probabilities of different SBP outcomes among pregnant women in LAUTECH Teaching Hospital, Oyo State. The results shows that age, packed cell volume and genotype increase the likelihood of having High Systolic Blood Pressure (HSBP), while blood group and occupation increase the likelihood of having low Systolic Blood Pressure (LSBP) among pregnant women. Also, the probabilities of increase in height and weight cause a systematic change in the SBP among pregnant women. The study concludes that the identified clinical and genetic risk factors contribute to the likelihood of having HSBP and LSBP among pregnant women in Ogbomoso, Oyo State.

Modeling changes in the quality attributes of couscous cooked with ohmic heating

Kinetic studies on the quality alters of couscous are crucial to the suitable design of ohmic heating treatment. Hence, it was targeted to build mathematical models to forecast the changes in quality attributes of couscous cooked using ohmic heating (OH) in the present study. In addition, the average power and total energy for cooking couscous with OH at a voltage gradient of 17 V/cm were determined. Three dissimilar kinetic models—zero, first, and second—were fitted to the data. Our findings showed that, for the ohmic heating system, as cooking time increased, energy consumption increased while heating system efficacy declined. The best model to reflect the changes in color parameters was the second-order model, while the zero-order model best fit the experimental data observed for the cooking loss, moisture content, and weight increase (%). For all TPA parameters, however, neither model yielded the greatest fit.
