Muscle characteristics of lower limb in association with physical activity in candidates of total knee arthroplasty with knee osteoarthritis

Background&AimsThis study aimed to clarify the association between physical activity (PA) and physical functions, including both muscle quantity and quality of ankle plantar flexor muscles in patients with knee osteoarthritis (OA). MethodsA retrospective cohort study was conducted with ninety-two patients with knee OA. PA, leg muscle cross-sectional area (CSA), knee strength, passive knee angle, and knee pain of the affected side were assessed. PA was assessed by the 2011 Knee Society scoring system. CSA of the quadriceps and ankle plantar flexor muscles on the affected side was measured using a computed tomography image. Based on muscle attenuation assessed with Hounsfield units (HU), the muscle quality of targeted muscle was divided into 4 groups as follows: fat tissue (-190 to -30 HU), very low-density muscle (-29 to -1 HU), low-density muscle (0 to 34 HU), and normal-density muscle (NDM, 35 to 100 HU). The CSA was obtained for each of the 4 groups. Univariate and multivariate linear regression analyses were performed to determine the factors associated with PA. ResultsThe regression analysis revealed that higher PA was independently associated with the NDM CSA of ankle plantar flexor (β = 0.51), higher knee extension strength (β = 0.28), and milder knee pain (β = -0.29) after adjustment with age, sex, height, weight, and body mass index. ConclusionThe present study suggested that NDM CSA of ankle plantar flexor in addition to knee function is one of the factors determining the PA in patients with knee OA.

A Study on the Allelopathic Effects of Wild Barley (Hordeum spontaneum) Residue Incorporated with Soil on Growth of Some Plant species

This study examines the allelopathic effects of wild barley (Hordeum spontaneum) on the growth and yield of bread wheat (Triticum aestivum), barley (Hordeum vulgare), and wild barley (Hordeum spontaneum). The experiment was conducted in a greenhouse at Shamamar-Hawler/ Kurdistan Region of Iraq using a complete randomized factorial design (CRD) within 3 replications. The roots, shoots, and seeds of wild barley were dried, powdered, and added to the soil at different concentrations (0%, 10%, 20%, 30%, and 40%) in 500 g pots. Each pot was planted with 5 seeds, which were later reduced to 3 seedlings. Growth parameters such as shoot and root lengths, dry weights, number of tillers, weight of spikes, seeds number per plant, and biological yield was measured. The results indicated significant effects of wild barley residues on the studied crops. Wheat showed the highest roots, shoots and total lengths were (29.56 cm, 17.05 cm and 46.58 cm, respectively) and the highest shoots and roots dry weights were (0.24 g and 0.30 g). Barley showed the highest number of stems (1.96) but the lowest shoots and dry weights of roots were (0.11 g and 0.23 g). Wild barley had the highest biological weight and harvest index (HI). Among the plant parts, seed extracts significantly enhanced growth parameters, while roots and shoots extract had the greatest inhibitory effects as wild barley residue concentrations increased. Nevertheless, the HI showed a decline as the concentrations increased, suggesting a detrimental effect on growth efficiency. The study shows the potential of wild barley as a bio-herbicide, emphasizing its allelopathic effects. This suggests that agricultural practices should be carefully considered to maximize the efficiency of crops. Incorporating these results into precision agriculture can greatly improve crop management and increase yield.

Unlocking vinpocetine's oncostatic potential in early-stage hepatocellular carcinoma: A new approach to oncogenic modulation by a nootropic drug.

The development of new drugs for the inhibition of hepatocellular carcinoma (HCC) development and progression is a critical and urgent need. The median survival rate for HCC patients remains disappointingly low. Vinpocetine is a safe nootropic agent that is often used to enhance cognitive function. The impact of vinpocetine on HCC development and progression has not been fully explored. Our main objective was to investigate the possible inhibitory role of vinpocetine in rats exposed to diethylnitrosamine. We observed that vinpocetine increased the survival rate of these rats and improved the ultrastructure of their livers. Additionally, vinpocetine reduced the liver weight index, mitigated liver oxidative stress, and improved liver function. In both in vitro and in vivo settings, vinpocetine demonstrated antiproliferative and apoptotic properties. It downregulated the expression of CCND1 and Ki-67 while exhibiting anti-BCL-2 effects and enhancing the levels of Bax and cleaved caspase-3. Vinpocetine also successfully deactivated NF-κB, STAT3, and HIF-1α, along with their associated transcription proteins, thereby exerting anti-inflammatory and anti-angiogenic role. Furthermore, vinpocetine showed promise in reducing the levels of ICAM-1 and TGF-β1 indicating its potential role in tissue remodeling. These findings strongly suggest that vinpocetine holds promise as a hepatoprotective agent by targeting a range of oncogenic proteins simultaneously. However, further approaches are needed to validate and establish causal links between our observed effects allowing for a more in-depth exploration of the mechanisms underlying vinpocetine's effects and identifying pivotal determinants of outcomes.

SYNTHESIS AND CHARACTERIZATION OF POLYEPICHLOROHYDRIN DIOLS

Polyepichlorohydrin (PECH) is a functional polymer with high value in energy materials. Cationic ring-opening polymerization of epichlorohydrin (ECH) with a diol initiator and Lewis or protic acids catalyst, proceeds through an activated monomer mechanism (AM) allowing control of the polymer's average molecular weight and polydispersity index. In the present investigation, PECH diol was synthesized under the catalysis of boron trifluoride etherate, with the ECH monomer:ethylene glycol as an initiator molar ratio of 1:0.045, achieving a low molecular weight nM = 1935 g/mol, low polydispersity index PDI = 1.25, predominantly in the linear chain configuration with the terminal hydroxyl group.

Serum autotaxin positively associates with hypertension in postmenopausal women: a single center study in China.

Autotaxin is an adipokine involved in metabolic disorders. The aim of the current study was to evaluate serum autotaxin levels in hypertensive postmenopausal women and establish a relationship between autotaxin and other comorbidities in this special group. This single-center study included postmenopausal women who received annual health examinations at the First Affiliated Hospital, College of Medicine, Zhejiang University in Zhejiang, China. The metabolic and demographic characteristics of the subjects, including age, sex, height, weight, blood pressure, and biochemical indices, were collected. The serum autotaxin level was measured via ELISA. The Kolmogorov-Smirnov test, Student's t test, Mann-Whitney U test, χ2 test, receiver operating characteristic (ROC) curve analysis, Spearman correlation analysis and multivariate logistic regression analysis were adopted for statistical analysis. This pilot observational study included 25 hypertensive postmenopausal women and 25 age-matched normotensive controls. Hypertensive patients presented significant metabolic disturbances with greater comorbidities such as nonalcoholic fatty liver disease, obesity, overweight, diabetes, hypertriglyceridemia and hyperuricemia (P < 0.05), impaired renal health with higher uric acid levels (P < 0.001), and slightly elevated creatinine levels (P = 0.156) with lower estimated glomerular filtration rates (eGFRs) (P = 0.195). The serum autotaxin level was markedly greater in the hypertensive group (239.0±59.6 ng/ml vs. 192.7 ± 49.0 ng/ml; P < 0.01) and was positively associated with systolic blood pressure; diastolic blood pressure; and alanine transaminase, triglycerides (TG), creatinine, and uric acid levels and inversely associated with the eGFR (P < 0.05) among postmenopausal women. Serum autotaxin levels positively predicted hypertension, with an AU-ROC of 0.750 [95% confidence interval (CI): 0.613-0.888] and a Youden index of 0.480 at a cutoff of 225 ng/ml. In the multivariate logistic regression analysis, after adjustment for demographic and metabolic parameters (including age, BMI, ALT, TB, uric acid, FBG, TG, LDL and creatinine), autotaxin (ATX) remained independently positively correlated with the risk of hypertension [odds ratio: 1.016, 95% CI 1.001-1.031; P < 0.05). Among postmenopausal women, the serum autotaxin level is significantly elevated in the hypertensive group compared with age-matched normotensive controls. ATX is related to multiple metabolic disorders and renal health, suggesting that autotaxin has potential as a multiorgan therapeutic target for cardiovascular-metabolic-renal disorders.

Tracking Smart Beta indices during different market phases: A “smarter” option for passive investors?

PurposeThis study aims to examine whether tracking Smart Beta (SB) indices during bullish, bearish and stagnant market phases is a better choice for passive investors compared to Cap-Weighted (CW) indices. As investors’ strategies differ with market movements, this study analyses how single-factor and multi-factor SB indices perform during different market phases, in relation to CW indices. It also attempts to determine which SB factors are more suitable for investors in these phases.Design/methodology/approachUsing various return and risk indicators, this study analyses how SB indices perform vis-à-vis CW indices during bullish, bearish and stagnant phases. The authors also evaluate the upside and downside participation advantage of SB indices and assess their ability to capture upside returns and limit downside risk. The authors attempt to determine the cyclical or defensive nature of SB indices using Average Participation values.FindingsThis study found that SB indices outperform CW indices during the bearish and stagnant phases. Multi-factor SB indices have lower risk levels in all market phases, providing downside protection to risk-averse investors. Dividend, Low Volatility, Quality and multi-factor SB indices are defensive portfolios offering better payoffs during the down market phases, while Alpha, Beta, Equal Weight and Value SB indices provide higher payoffs during the up-market phases.Originality/valueTo the best of the authors’ knowledge, this is the first study that examines the performance of single-factor and multi-factor Indian SB indices in different market phases. It determines the suitability of various factors to passive investors during these phases and also identifies whether SB indices are cyclical or defensive.

Impact of body weight and body mass index on clinical outcomes of edoxaban therapy in atrial fibrillation patients included in the ETNA-AF-Global registry

Abstract Background In atrial fibrillation (AF) patients (pts) receiving non-vitamin K antagonist oral anticoagulant therapy, extreme body weights, both obesity and low body weight, may impact clinical outcomes. Purpose To determine the impact of body weight and body mass index (BMI) on clinical outcomes in AF pts receiving edoxaban from the Global ETNA program (Europe [NCT02944019], Japan [UMIN000017011], Korea/Taiwan [NCT02951039], Hong Kong [NCT03247582] and Thailand [NCT03247569]). Methods ETNA-AF-Global, a multinational, prospective, observational study collected demographic and clinical outcomes data for AF pts receiving edoxaban. In this subanalysis, pts were categorised into the following body weight groups: ≤60kg, &amp;gt;60 to 80kg (reference body weight), &amp;gt;80 to ≤100kg and &amp;gt;100kg; and BMI groups: &amp;lt;18.5kg/m², ≥18.5 to &amp;lt;25.0kg/m² (reference BMI), ≥25.0 to &amp;lt;30.0kg/m², ≥30.0 to &amp;lt;40.0kg/m² and ≥40.0kg/m². Clinical outcomes at 2-year follow-up were compared across body weight and BMI groups. Results 26,805 pts were included in this analysis. Mean ± standard deviation body weight was 72.2 ± 18.1kg and mean BMI was 26.4 ± 5.0kg/m². 43.7% of pts were categorised into the &amp;gt;60 to 80kg reference body weight group. [other groups: ≤60kg, 28.1%; &amp;gt;80 to ≤100kg, 21.7%; &amp;gt;100kg, 6.5%] and 40.0% of pts into the ≥18.5 to &amp;lt;25.0kg/m² reference BMI group [other groups: &amp;lt;18.5kg/m², 3.0%; ≥25.0 to &amp;lt;30.0kg/m², 37.3%; ≥30.0 to &amp;lt;40.0kg/m², 18.0%; ≥40.0kg/m², 1.7%]. Clinical outcomes are shown in Fig. 1 as unadjusted hazard ratios vs. reference group according to weight and in Fig. 2 according to BMI. Among body weight groups, pts weighing ≤60kg had the highest annualised rates of any stroke or systemic embolic event (SEE; 1.24%), ischemic stroke (0.97%), all-cause death (3.96%), major bleeding events (1.49%), and major bleeding or clinical-relevant non-major (CRNM) bleeding events (3.45%). Pts in the reference body weight group had the lowest annualised rates of all-cause death (2.81%). Annualised rates of major bleeding, major bleeding or CRNM bleeding events and any stroke or SEE were lowest in pts weighing &amp;gt;100kg. Among BMI groups, annualised rates of all effectiveness and safety outcomes were highest in pts with a BMI &amp;lt;18.5kg/m². Pts in the ≥25.0 to &amp;lt;30.0kg/m² BMI group had the lowest annualised rates of all-cause death (2.85%) and pts in the ≥18.5 to &amp;lt;25.0kg/m² BMI group had the lowest annualised rates of CV death (0.73%). Conclusions In the Global ETNA-AF program, clinical outcomes varied between different body weight and BMI subgroups. These findings highlight the need to consider the clinical implications of low body weight and/or low BMI, as AF pts who belong to these categories may be at higher risk of adverse outcomes during long-term anticoagulant treatment.Figure 1.Figure 2.

Elevation of circulating FGF23 in chronic kidney disease promotes atrial fibrosis through the AKT pathway

Abstract Background The relationship between chronic kidney disease (CKD) and atrial fibrillation (AF) remains unclear. Elevated level of fibroblast growth factor 23 (FGF23) is highly associated with increased cardiovascular disease and mortality in patients suffering from CKD. In recent years, studies have shown that FGF23 promotes cardiac hypertrophy through FGFR4, suggesting that FGF23 may be an important bridge between the heart and kidney. Purpose In this study, we sought to use a well-established rat model of CKD to further characterize the effects of CKD on AF and to identify potential drivers of CKD-induced AF. Methods 14 SD rats were randomly selected to undergo 5/6 nephrectomy and fed for 15 weeks to establish a CKD model, while the SHAM group (8 rats) underwent the same surgery without removing kidney tissue. Body weight, blood pressure, renal function, cardiac ultrasound, epicardial electrocardiography, and pathological indices were monitored in both groups. Gene sequencing was performed on the left atria to search for differentially expressed genes. Rat atrial fibroblasts were selected for further mechanism exploration. We chose TGF-β to stimulate fibroblasts to mimic the process of fibrosis in vivo, and then administered FGFR inhibitors to explore the downstream molecular mechanisms. Results Systolic blood pressure and creatinine were elevated in the CKD group. Compared with the SHAM group, the incidence of AF was significantly higher, left atrial diameter was significantly larger, and epicardial electrical markers showed that left atrial electrical conduction velocity was significantly slower and conduction heterogeneity was significantly increased in the CKD group. Pathologic staining of the left atrium showed significant fibrosis in the CKD group. Consistent with previous findings, FGF23 was significantly elevated in CKD rats. Transcriptomic sequencing revealed that FGFR4 expression was significantly upregulated in the left atrium of CKD rats, The results in rat atrial fibroblasts showed that blocking FGFR4 expression inhibited TGF-β-induced fibrosis and was mediated by the AKT pathway. Conclusions The mechanism of CKD-induced AF is that CKD promotes both structural and electrical remodeling of the atria. Further investigation of its possible downstream molecules revealed that elevated FGF23 in the CKD circulation promotes the development of atrial fibrosis by binding to FGFR4 through the AKT pathway.

Effect of incremental exercise training interventions in a Cardiac Rehabilitation Program following myocardial infarction

Abstract Background Exercise-based cardiac rehabilitation is recommended after myocardial infarction (MI) to improve prognosis, quality of life and control of cardiovascular risk factors. However, the specific impact of different exercise training interventions remains incompletely understood. Purpose To study the health outcomes of three incremental exercise training interventions during a Cardiac Rehabilitation Program (CRP) following MI. Methods We implemented a post-MI Phase 2 CRP in 2022. After initial exercise testing, a 3-month, individualized aerobic and strength ambulatory training program was provided by Cardiologists and Physical Medicine and Rehabilitation physicians (Group 1, n=58). Additionally, a subset of patients received one session of supervised teaching of aerobic and strength training by physiotherapists (Group 2, n=19), and another subset received 8-20 sessions of in-hospital supervised training (Group 3, n=13). Exercise testing was repeated at the end of Phase 2 and peak oxygen consumption (peak VO2) was measured. We analysed quality of life (SF-36), depression (PHQ2), anxiety (GAD2), adherence to Mediterranean diet (PREDIMED) and pharmacological treatment (Morisky-Green), and weekly physical activity (IPAQ). Health outcomes were compared at the beginning and after Phase 2 CRP. Results The cohort comprised 90 patients who completed Phase 2 CRP (mean age 61.2±10.8 years, 84.4% male and 47.8% smokers). Reductions in systolic blood pressure (-10.3±13.8mmHg), LDL cholesterol (-60.7±35.4mg/dL), weight (-2.8±6.6kg, -3±7.8%) and body mass index (-1±2.2) were attained (p&amp;lt;0.05). Smoking abstinence was accomplished in 88.4% of smokers and most patients achieved an LDL&amp;lt;55mg/dL (81.1%). Improvements in quality of life (SF-36 +10.4±19.4 points, p&amp;lt;0.001) and anxiety and depression symptoms (PHQ2 -0.5±1.6 points and GAD2 -0.6±1.6 points, p&amp;lt;0.01) were noted. An increase in peak VO2 (+5.12±5.44ml/kg/min, +23.5±27.4% from baseline, p&amp;lt;0.001) and predicted functional capacity (+13.4±23.8%, p&amp;lt;0.001) was achieved. Patients increased their reported weekly physical activity by 2520.3±2935.4 METS/week (+132% from baseline, p&amp;lt;0.001) and most of them were adherent to Mediterranean diet (91.1%) and pharmacological treatment (95.6%). Patients achieved similar health outcomes regardless of their exercise training group, except for patients in Group 3, who experienced a more pronounced improvement in peak VO2 (+8.1±6.4ml/kg/min, +37.8±34.7% from baseline; p&amp;lt;0.05) and a trend towards higher increase in predicted functional capacity (+21.7±19.2%, p&amp;lt;0.25) and greater weight loss (-5.5±9.4kg, -5.9±9.6%; p&amp;lt;0.2). Conclusions Supervised in-hospital training during a Phase 2 CRP provides superior physical fitness improvements and more pronounced weight loss in MI patients. However, a Phase 2 CRP based on ambulatory training provides similar benefits regarding other health outcomes, such as control of cardiovascular risk factors and quality of life amelioration.Exercise training interventions in a CRP

Clinical impact of Sarcopenia on long-term mortality in patients undergoing coronary bypass grafting

Abstract Background Sarcopenia is an aging-related condition characterized by loss of skeletal muscle mass and is an indicator of subclinical atherosclerosis. The relationship between sarcopenia and long-term clinical outcomes in patients with advanced coronary artery disease who have undergone coronary artery bypass grafting (CABG) is not fully understood. This study aimed to evaluate the prognostic implications of sarcopenia in patients undergoing CABG. Methods A total of 2,810 patients who underwent CABG were derived from the Samsung Medical Center institutional registry from 2007 to 2017 and classified according to the presence of sarcopenia. The skeletal muscle index (SMI) was calculated as L3 muscle area (cm2)/height (m)2 on computed tomography. Sarcopenia was defined as SMI ≤45 cm2/m2 in men and ≤38 cm2/m2 in women. The primary outcome was all-cause mortality during follow-up. Results The median follow-up was 8.7 years, and 924 patients (32.9%) had sarcopenia. Patients with sarcopenia were older and more frequently women. SMI was significantly correlated with age (R=-0.34, P&amp;lt;0.001), weight (R=-0.56, P&amp;lt;0.001), and body mass index (R=-0.52, P&amp;lt;0.001). SMI was significantly associated with risk of death on a restricted cubic spline curve (HR=1.04 per-1 decrease, 95% CI 1.03-1.05, P&amp;lt;0.001). Patients with sarcopenia had a higher incidence of long-term mortality than those without sarcopenia (survival rate 41.4% vs. 62.8%; adjusted HR=1.18, 95% CI 1.03-1.36, P=0.02). Subgroup analysis showed that the prognostic implication of sarcopenia on long-term survival was more evident in men (adjusted HR=2.01, 95% CI 1.72-2.35) than women (adjusted HR=1.28, 95% CI 0.98-1.68) (interaction P=0.006). Conclusions Sarcopenia, defined by SMI on computed tomography, was associated with long-term mortality after CABG. These results provide contemporary data to allow the evaluation of physical frailty in patients with advanced coronary artery disease before surgery.

NIpple Position to Pinpoint Localization of Chest Drain Insertion in FEmale Trauma Patients: The NIPPLE-Trial-A Landmark Study.

Background: The insertion of chest drains (CD) in trauma patients is a lifesaving, albeit high-risk intervention. Safe insertion of CD in settings where aids like ultrasound are not available relies on a landmark technique defining the so-called triangle of safety. The inferior margin of this triangle is identified by nipple height, which is thought to correspond to the fifth intercostal space (ICS). Training manikins are modeled after a lean male body and oftentimes insinuating jokes fuel uncertainty about the height of the nipple as a reliable landmark in female trauma patients. This study aims to prove that the nipple can be considered a safe landmark for CD insertion in women: even if larger breasts follow the force of gravity, it should not act towards the direction of the feet, but to the sides of the thorax in a flat-lying trauma patient. Methods: An online questionnaire was designed and distributed amongst female surgeons. Epidemiological data (age, nr of pregnancies, history of breastfeeding) was collected. Height, weight, and body mass index (BMI) were reported. Chest circumference and underbust girth were self-measured. The nipple position in relation to the ICS was measured by the women while lying in a supine position. Results: 237 female surgeons completed the questionnaire. Nine questionnaires were excluded due to incomplete data sets. 20 women were excluded due to previous breast surgery. Thus, 208 participants (or 416 nipples) were included in analysis. In supine position, both nipples were located in the 5th (±0.8) intercostal space. Age, BMI, height, weight, and status post-pregnancy had no significant impact on nipple position. Interestingly, a history of breastfeeding correlated with lower nipple position. Conclusions: The nipple is a safe landmark for identifying the correct insertion position of chest drains in supine-lying female trauma patients.

Evaluation of Field Performance of Groundnut Varieties through Different Vigour Tests

A field experiment was carried out to evaluate the field performance of groundnut varieties through different vigour tests during Rabi, 2023-24 at S.V. Agricultural College, Tirupati, Acharya N.G. Ranga Agricultural University, Andhra Pradesh. The experimental material consisted of 10 groundnut varieties Narayani, Dharani, Dheeraj, TCGS-1694, Nithya Haritha, Kadiri-9, Kadiri-6, Kadiri Amaravathi, Kadiri-1812 and TAG-24 collected from different sources. In the preliminary experiment seed multiplication was done and the multiplied seed was used for conducting six vigour tests namely Germination test, speed of germination test, Seedling vigour index-Ⅰ, Seedling vigour index-Ⅱ, Accelerated ageing test, Electrical conductivity test in the laboratory using Completely Randomised Design with four replications. The multiplied seed was used for evaluating field performance using Randomised block design with three replications. Significant differences were found among the varieties based on vigour levels. Results with respect to field experiment showed that growth parameters i.e. field emergence percentage, days to 50 % flowering, days to maturity, number of branches per plant, number of pods per plant, pod yield per plant, kernel yield per plant, pod yield per plot, plant height, shelling percentage, 100 seed weight and harvest index varied significantly among different varieties based on different vigour levels. Varieties with higher vigour had shown higher field emergence percentage. Among the ten varieties Kadiri-6 had shown highest field emergence percentage. Significant correlation was observed among laboratory and field experiments. Vigorous varieties were able to perform better in terms of some of the field parameters and among all the vigour tests performed speed of germination test had high correlation with field emergence.

Fabrication and Optimization of a Silodosin In Situ-Forming PLGA Implants for the Treatment of Benign Prostatic Hyperplasia: In Vitro and In Vivo Study

Objectives: Lower urinary tract symptoms (LUTSs) related to benign prostatic hyperplasia (BPH) are common in older men, and alpha-adrenoceptor blockers continue to be a key part of managing these symptoms. This study aimed to formulate injectable poly (lactic-co-glycolic acid) (PLGA) in situ-forming implants (ISFIs) loaded with silodosin (SLD) to address symptoms associated with BPH. This method, which ensures prolonged therapeutic effects of SLD, is intended to decrease dosing frequency and improve treatment outcomes, leading to better patient adherence. Methods: An appropriate solvent with favorable PLGA solubility, viscosity, and in vitro release profile was selected. Additionally, an I-optimal design was employed as an optimization technique. An in vivo study in albino male rats was conducted to investigate prostate-specific antigens (PSAs), prostate weight and prostatic index, histopathology, and SLD pharmacokinetics. Results: The optimized formulation showed experimental values of 29.25% for the initial burst after 2 h and 58.23% for the cumulative release of SLD after 10 days. Pharmacokinetic data revealed that the SLD–ISFI formulation had lower Cmax and higher AUC values than subcutaneous (SC) pure SLD and oral commercial SLD capsule, indicating the controlled-release impact and improved bioavailability of the ISFI systems. SLD–ISFI produced a marked drop in the prostatic index by 2.09-fold compared to the positive control. Serum PSA level decreased significantly from 0.345 ± 0.007 to 0.145 ± 0.015 ng/mL after SLD–ISFI injection compared to the positive control. Conclusions: This study indicated that the optimized SLD–ISFI formulation proved its efficacy in managing BPH.

Immunostimulation Signaling via Toll-like Receptor 2 Activation: A Molecular Mechanism of Lactococcus lactis OTG1204 In Vitro and In Vivo.

The immune system's defense against pathogens involves innate and adaptive responses, crucial in maintaining overall health. Immunosuppressed states render individuals more susceptible to potential diseases, indicating the need for effective strategies to bolster immune functions. Although the immunostimulatory effects of various probiotics have been studied, the specific effects and molecular mechanisms of Lactococcus lactis OTG1204 (OTG1204) remain unknown. In this study, the aim was to investigate the molecular mechanisms of OTG1204 in RAW 264.7 macrophages, the key effector cells of the innate immune system involved in host defense and inflammatory responses. Additionally, in this study, the effects of OTG1204 on cyclophosphamide (CTX)-induced immunosuppression states were investigated, thereby demonstrating its potential as an immune stimulant. To assess the macrophage activation ability and underlying mechanisms of OTG1204, RAW 264.7 cells were utilized with transfection, enzyme-linked immunosorbent assay, and quantitative real-time PCR analyses. Furthermore, to evaluate the immunostimulatory effects under immunosuppressed conditions, CTX-induced immunosuppression mice model was employed, and analyses were performed using hematoxylin and eosin staining, flow cytometry, and microbiota examination. OTG1204 activated RAW 264.7 macrophages, leading to increased production of nitric oxide, prostaglandin E2, and cytokines. This immune activation was mediated through the upregulation of toll-like receptor 2, which subsequently activated the nuclear factor-κB (NF-kB) and mitogen-activated protein kinase (MAPK)/activator protein 1 (AP-1) pathways, thereby stimulating the immune response. In CTX-treated mice, OTG1204 recovered body weight, spleen, and mesenteric lymph node indices, and natural killer cell activity. It re-established populations of innate and adaptive immune cells and activated T cells to secrete cytokines. We also examined the gut barrier integrity and microbiota composition to assess OTG1204's impact on intestinal health, as these factors play a significant role in immune enhancement. OTG1204 enhanced gut barrier integrity by upregulating mucin 2 and tight junction proteins and modulated the gut microbiota by restoring the Firmicutes/Bacteroidetes balance and reducing the abundance of Actinobacteria and Tenericutes. These results suggest that OTG1204 may serve as an effective probiotic for immune enhancement and gut health management by targeting the NF-κB and MAPK/AP-1 pathways, with minimal side effects.

Irrigation suitability assessment of urban wastewater for sustainable agriculture: a case study of Musi river, India

In urban areas with dense populations and high water demands, effective management of water resources is crucial for sustainable development. It includes optimizing water usage and recycling wastewater to balance supply and demand. Urban rivers, which now carry sewage year-round due to increased urban water consumption, are increasingly used for irrigation in peri-urban regions. This study aims to assess the suitability of an urban stream for irrigation compared to catchment groundwater, using hydrochemical parameters to evaluate water quality indices. Analysis of major ion distribution from upstream to downstream reveals a significant increase of TDS (r2 = 0.65; p < 0.001) in the surface water and a decrease (r2 = 0.93; p < 0.001) in groundwater samples. The calculated Weighted Arithmetic-Water Quality Index (WA-WQI) indicates that around 85% and 75% of surface water and groundwater samples from the Musi river are classified as very poor to unsuitable for any use, highlighting critical pollution levels. Based on irrigation suitability indices, only 16% of the surface water samples and 60% of the groundwater samples are suitable for irrigation. The nitrate concentration increased from less than 10 mg l−1 in the upstream region to over 100 mg l−1 in the urban stretch. Nitrogen-Phosphate-Potassium (NPK) ratios across the basin are exceptionally higher, representing crops irrigated using the Musi river water might not require fertilizer applications. The adoption of fertilizer application concerning supplied water hydrochemistry, particularly the NPK ratio, might limit the excess usage of fertilizer and benefit farmers. Additionally, this practice may also limits the excess input of nitrate to the groundwater in the Musi river basin.

Assessment of the Scholastic Performance and Cognitive Functions in Malnourished Children of Primary and Secondary Class Students

Abstract Background: Malnutrition is the consequence of a combination of deficiencies in protein, carbohydrates, and micronutrients. It includes undernutrition, overnutrition, and micronutrient deficiencies. Malnutrition is associated with both structural and functional pathology of the brain and reflects in poor scholastic performance and less cognitive functions in children. Aim: The aim of the study was to assess the scholastic performance and cognitive functions in malnourished children of primary and secondary classes studying in a school. Methodology: The study was conducted on 375 school children of primary and secondary classes. The nutritional status was assessed using the World Health Organization growth charts and classified based on their weight, height, and body mass index with malnutrition considered with values &lt;−2 standard deviation for the age group. The scholastic performance was assessed using the school annual examination records and classified as good or poor scholastic performance with cutoff mark criteria of 50%. The cognitive function was assessed using the child mini–mental state examination (MMSE) test with the mean score for the age group. The scholastic performance and cognitive function were compared between the normal and malnourished groups. The variables were compared with respect to age, gender, standard, and P value obtained to see its significance. The variables were compared between the two groups in each class and test results were obtained. The correlation between each of the variables was also done. Results: Malnourished children were more in the primary classes (30%) than the secondary classes (13.2%). The scholastic performance in the normal group was increased than the malnourished group in both primary and secondary classes. The cognitive function based on the child MMSE score was also more in the normal group than in the malnourished group in both primary and secondary classes. There was a positive correlation between scholastic performance and cognitive function. Conclusion: The study results showed that the scholastic performance and cognitive function were decreased in the malnourished group than the normal group in both primary and secondary classes, implying that malnutrition affects the functionality of the brain and can cause long-term effects like poor cognition.

Clinician Staffing and Quality of Care in US Health Centers

Health centers are vital primary care safety nets for underserved populations, but optimal clinician staffing associated with quality care is unclear. Understanding the association of clinician staffing patterns with quality of care may inform care delivery, scope-of-practice policy, and resource allocation. To describe the association of clinician staffing models and ratios with quality-of-care metrics in health centers. This cross-sectional study of US health centers used data from the 2022 Health Resources and Services Administration Uniform Data System (UDS). Clinician staffing ratios, expressed as the fraction of full-time equivalents (FTEs) per 1000 visits of physicians, advanced practice registered nurses (APRNs), and physician associates (PAs) to total clinician FTEs at each health center. Percentage of eligible patients receiving the corresponding service or outcome for 14 individual clinical quality metrics collected by the UDS, including infant immunizations; screening for cancer, depression, tobacco use, hypertension, HIV, and glycated hemoglobin levels; weight and body mass index (BMI) assessment; and appropriate statin, aspirin, and/or antiplatelet therapy. This analysis of 791 health centers serving 16 114 842 patients (56.6% female) identified 5 clinician staffing models: balanced (similar FTEs of physicians, APRNs, and PAs; 152 [19.2%] of health centers), higher FTEs of APRNs than physicians (174 [22.0%]), higher FTEs of physicians than APRNs (160 [20.2%]), approximately equal FTEs of physicians and APRNs (263 [33.2%]), and large scale (42 [5.3%]). Adjusted linear models showed positive associations between physician FTEs per 1000 visits and cervical (β, 14.9; 95% CI, 3.1-26.7), breast (β, 15.7; 95% CI, 3.2-28.1), and colorectal (β, 18.3; 95% CI, 6.0-30.6) cancer screening. Generalized additive models showed nonlinear positive associations beginning at a physician FTE ratio of 0.45 (95% CI, 0.02-6.22) for infant vaccinations, 0.39 (95% CI, 0.05-2.21) for cervical cancer screening, 0.39 (95% CI, 0.02-1.67) for breast cancer screening, 0.47 (95% CI, 0.00-5.76) for HIV testing, and 0.70 (95% CI, 0.18-19.96) for depression in remission; APRN FTE ratio of 0.45 (95% CI, 0.17-7.46) for adult BMI assessment; and PA FTE ratio of 0.16 (95% CI, 0.11-3.88) for infant vaccinations. Staffing models were not associated with 7 of the 14 metrics analyzed. In this cross-sectional study of health centers, physician FTE ratio was associated with higher performance in cancer screening, infant vaccinations, and HIV testing; APRN FTE ratio was associated with higher performance in preventative health assessments; and PA FTE ratio was associated with higher performance in infant vaccination. These findings suggest that targeted staffing strategies may be associated with quality of care in certain domains and that tailored approaches to health center staffing based on community-specific needs are warranted.

Delphinidin or α-amyrin attenuated liver steatosis and metabolic disarrangement in rats fed a high-fat diet.

Non-alcoholic fatty liver disease (NAFLD) is a liver pathology concomitant with metabolic disarrangement. This study assessed the therapeutic impacts of delphinidin, an anthocyanin, or α-amyrin, a pentacyclic triterpenoid, on NAFLD in rats and the underlying mechanisms involved. NAFLD was established by feeding a high-fat diet (HFD) for 10 weeks, either alone or in combination with delphinidin (40 mg/kg, oral) or α-amyrin (20 mg/kg, oral). Delphinidin or α-amyrin ameliorated the metabolic and histopathological perturbations induced by HFD. These compounds markedly attenuated NAFLD-induced hepatic steatosis, as evidenced by a substantial decrease in body weight, insulin resistance, and liver and adipose tissue indices. Alongside normalization of the atherogenic index, both improved HFD-mediated abnormalities in serum lipids, liver enzymes, leptin, and ghrelin levels. Moreover, their intervention activated the NFE2 like bZIP transcription factor 2 and heme oxygenase 1 pathways and abrogated HFD-triggered activation of mitogen-activated protein kinase 1 signaling. These remedies inhibited hepatic apoptosis and modulated the gene expression of lipogenic enzymes. Furthermore, histological analysis corroborated the suppression of lipid accumulation and amelioration of hepatic architecture in the treated rats. Our findings highlight the hepatoprotective value of delphinidin or α-amyrin against NAFLD and related metabolic diseases through their insulin-sensitizing, anti-inflammatory, antioxidant, and antiapoptotic effects.

Associations of different genotypes with the meat productivity of sheep

Identification of the potential to increasthe agricultural production of farm animals has become possible through the use of genomic selection methods. It is advisable to improve breeding and pedigree qualities of local breeds, since these have the best adaptability to the features of the natural and geographical conditions in a given area. He controlled slaughter of animals with different genotypes allowed us to determine their meat qualities, such as biological value, slaughter yield and slaughter weight. The ratio of slaughter weight and pre‐slaughter weight gives the slaughter yield in percent.PCR (polyamino acid chain reaction) using specific synthesised sets of oligonucleotides in the genotyping of experimental sheep populations was carried out in order to study the allelic variants of the CAST and GH genes.When studying the indices characterising body weight in sheep which have different genotypes, significant increases in the indices could be observed before the periods of driving to summer pastures (17.2 kg) and during lambing (25.8 kg). The lowest indices were noted during driving both from winter pastures to summer pastures and from summer pastures to winter pastures (30.5 kg).In the period before driving, the live weight index was higher in the CASTMM genotype by 5.8 %; upon arrival in the mountains the difference was 6.1 %; during lambing — 4.7 %; before leaving for winter pastures — 8.4 % and upon arrival at winter pastures — 9.5 %.

Coated oregano essential oil and cinnamaldehyde compounds supplementation improves growth performance, enhances immune responses, and inhibits cecal Escherichia coli proliferation of broilers.

Plant essential oils are unstable due to high volatility and easy oxidation, while microencapsulation provides a potentially effective strategy for increasing the stability of natural essential oils and preserving their function. This study examined the effects of feeding coated oregano essential oil and cinnamaldehyde (COEC) compounds on growth, immune organ development, intestinal morphology, mucosal immune function, and the cecal microbiota populations of broilers. Three hundred one-day-old male Arbor Acres broiler chicks were organized into 5 groups: 1) negative control fed basal diet alone (NC), 2) positive control receiving basal diet plus 50mg/kg of chlortetracycline (CTC), 3) basal diet plus 150mg/kg COEC (COEC150), 4) plus 300mg/kg COEC (COEC300), and 5) plus 450mg/kg COEC (COEC450). The supplement trial was continued for 42 d. The results showed that CTC, COEC300, and COEC450 treatments decreased the feed conversion ratio of broilers both in the starter and whole experiment phases, increased the height of jejunal villi at 21 d and the number of goblet cells and IgA-producing cells at 21 or 42 d compared with NC group (P < 0.05). Members of the COEC300 treatment group had a higher thymus weight index and jejunum length index than birds of NC or CTC groups at 21 d (P < 0.05). CTC and all COEC treatments decreased malondialdehyde content in jejunal mucosa at 42 d (P < 0.05). The population of Escherichia coli (E. coli) in the cecal digesta at 21 d was lower in the CTC, COEC300, and COEC450 treatment groups compared with the NC group (P < 0.05). In contrast to the CTC group, COEC supplementation dose-dependently accelerated body weight gain, improved jejunal morphology, decreased malondialdehyde content in jejunal mucosa, increased numbers of jejunal goblet cells and IgA-producing cells, and decreased the E. coli population in cecal digesta at 21 or 42 d (P < 0.05). Thus, we concluded that feeding broiler chickens with 300 or 450mg/kg in antibiotic-free diets can improve growth performance, enhance immune responses, and inhibit the proliferation of cecal pathogenic bacteria.
