Graphene oxide–silver (Ag–GO) nanocomposite has emerged as a vital antibacterial agent very recently. In this work, we report a facile one step route of Ag–GO nanocomposite formation excluding the aid of surfactants and reductants and was successfully applied to negative Escherichia Coli ( E coli ) to investigate antibacterial activity by varying doze concentration. The successful formation of Ag–GO nanocomposite via facile one step route was confirmed using Fourier transform infrared spectroscopy (FTIR) and Raman Spectroscopy. The absorption spectra (peak ~ 300 nm) for GO and the (peak ~ 420 nm) for silver nanoparticles were observed. XRD study confirmed the formation of Ag–GO nanocomposite while atomic force microscopy (AFM) showed crumbled GO sheets decorated with Ag nanoparticles. It was observed that the functional groups of GO facilitated the binding of Ag nanoparticles to GO network and enhanced the antibacterial activity of the nanocomposite.

Nicardipine is a calcium channel blocker employed to manage hypertension and angina. It is primarily metabolized in the liver; therefore, hepatic impairment patients may experience drug accumulation, potentially resulting in adverse events. This research aims to design physiologically based pharmacokinetic (PBPK) model capable of accurately predicting the exposure of nicardipine in healthy individuals as well as hepatic and renal impairment patients. An extensive literature review was conducted to retrieve relevant articles and pharmacokinetic (PK) parameters of nicardipine, for integration into the PK-Sim ® program. The modeling approach incepts with the development of healthy PBPK model, which is subsequently extrapolated to diseased populations to assess the alignment of anticipated and reported concentration-time profiles. The precision of the model was then evaluated through visual predictive checks, mean observed–predicted ratios, and average fold error across relevant PK parameters, which adhered to the predefined 2-fold threshold. The observed exposure of nicardipine in Child-Pugh A was found to be ~ 1.5-fold greater than in a healthy population, highlighting the necessity of dosage adjustment in the cirrhotic population. The developed PBPK models have effectively elucidated the PK alterations of nicardipine in healthy and diseased populations, thus the insights gained from these models can inform tailored dosing regimens for enhancing therapeutic efficacy.

This study explores the influence of forecasted earnings to price ratio (E/P) and ROE to explain the part of the variation in the Shanghai Stock Exchange (SSE) returns. The study analyzed the explanatory capacity of fundamental, risk, and combined valuation approaches variables on comparative mode between static and dynamic models with the induction of un-balanced panel data estimation. A linear dynamic panel technique is being undertaken to forecast the variables. The research findings indicate that the forecasted E/P ratio and ROE significantly explain the variation in SSE stock return and remain highly statistically significant after incorporating risk proxy variables. Moreover, the author also confirms the existence of size, momentum, liquidity, and dividend yield in the Shanghai Stock Exchange. The study introduces the fundamental valuation approach to the Chinese market based on its unique features and designs a log-linear model, which comprises forecasted E/P and ROE in addition to current E/P as an estimator for future stock returns. The incorporation of Driscoll and Kraay standard errors (DKSE) and Panel Corrected standard error (PCSE) under static while difference and system GMM under the scope of dynamic panel estimation is considered to be another contribution of the study.

Background In drug development, few molecules from a large pool of early candidates become successful medicines after demonstrating a favourable benefit-risk ratio. Many decisions are made along the way to continue or stop the development of a molecule. The probability of pharmacological success, or PoPS, is a tool for informing early-stage decisions based on benefit and risk data available at the time. Results The PoPS is the probability that most patients can achieve adequate pharmacology for the intended indication while minimising the number of subjects exposed to safety risk. This probability is usually a function of dose; hence its computation typically requires exposure–response models for pharmacology and safety. The levels of adequate pharmacology and acceptable risk must be specified. The uncertainties in these levels, in the exposure–response relationships, and in relevant translation all need to be identified. Several examples of different indications are used to illustrate how this approach can facilitate molecule progression decisions for preclinical and early clinical development. The examples show that PoPS assessment is an effective mechanism for integrating multi-source data, identifying knowledge gaps, and forcing transparency of assumptions. With its application, translational modelling becomes more meaningful and dose prediction more rigorous. Its successful implementation calls for early planning, sound understanding of the disease-drug system, and cross-discipline collaboration. Furthermore, the PoPS evolves as relevant knowledge grows. Conclusion The PoPS is a powerful evidence-based framework to formally capture multiple uncertainties into a single probability term for assessing benefit-risk ratio. In GSK, it is now expected for governance review at all early-phase decision gates.

Background: Although parenting interventions are effective in improving parenting practices and child development, most are developed within Western cultural frameworks that may not align with South Asian collectivist values and family structures. The extent to which cultural adaptation influences the effectiveness of parenting interventions in South Asian populations remains unclear. Aim: To systematically review the effectiveness of parenting interventions on child developmental outcomes, parenting outcomes, and parental health among South Asian families, and to examine whether the depth of cultural adaptation, assessed using Bernal’s Ecological Validity Model (EVM), is associated with intervention effectiveness. Methods: A systematic review and meta-analysis were conducted. We systematically searched CINAHL, MEDLINE, Science Direct, PsychINFO, PubMed, and Cochrane library. Data were extracted from six electronic databases up to August 2023. Quality and risk of bias were appraised using the Revised Cochrane Risk of Bias Tool for Randomized Trials for the quantitative studies and the Critical Appraisal Skill Program (CASP) checklist for the qualitative studies. Results: Seventeen studies (fifteen quantitative, two qualitative) involving 8088 participants were included; ten studies contributed data to meta-analysis. Parenting interventions were associated with moderate improvements in parenting knowledge (SMD = 0.51, 95% CI 0.25 to 0.76) and small improvements in parental involvement (SMD = 0.36, 95% CI 0.00 to 0.72). Significant reductions in parental depression (SMD = −0.77, 95% CI −1.20 to −0.34) and disability symptoms (SMD = 0.82, 95% CI 0.68 to 0.96) were observed, though effects on post-natal depression (SMD = 0.15, 95% CI −1.00 to 1.30) and physical quality of life (SMD = −0.27, 95% CI −1.22 to 1.75) were non-significant. For children, large improvements were found in cognitive (SMD = 0.84–1.48), language (SMD = 0.79, 95% CI 0.25 to 1.33), and social development (SMD = 0.54, 95% CI 0.16 to 0.91), but not in emotional or motor development. Sensitivity analyses indicated larger effects for studies demonstrating deeper cultural adaptation. Qualitative findings highlighted maternal empowerment, improved mental wellbeing, and the importance of family support and culturally congruent facilitators for engagement. Overall certainty of evidence was rated as low due to high heterogeneity, risk of bias, and imprecision. Discussion: Culturally adapted parenting interventions show promising benefits for parenting practices, parental mental health, and child developmental outcomes among South Asian families, particularly when adaptations extend beyond surface-level changes. However, evidence quality is low and inconsistent, highlighting the need for more rigorous trials and clearer reporting of cultural adaptation to optimize effectiveness.

Objectives were to determine the effects of supplementing increasing amounts of choline ion on hepatic composition and mRNA abundance in pregnant dry cows subjected to a fatty liver induction protocol. Holstein cows (35 primiparous and 41 multiparous) at mean (± standard deviation) of 211 ± 9.9 days of gestation were blocked by body condition (3.59 ± 0.33) and assigned to receive 0, 6.45, 12.90, 19.35, and 25.80 g/day of choline ion as rumen-protected choline (RPC) as a top-dress for 14 days. Cows were fed for ad libitum intake on days 1 to 5 and restricted to 30% of the required net energy for lactation from days 6 to 14 of the experiment. Hepatic tissue was sampled on days 5 and 14 and analyzed for concentrations of triacylglycerol and glycogen, and mRNA abundance was investigated. Orthogonal contrasts evaluated the effects of supplementing RPC (0 g/day vs. rest), and the linear, quadratic, and cubic effects of increasing intake of choline ion from 6.45 to 25.80 g/day. Results are depicted in sequence of treatments from 0 to 25.8. During feed restriction, RPC reduced the concentration of hepatic triacylglycerol by 28.5% and increased that of glycogen by 26.1%, and the effect of increasing RPC intake on triacylglycerol was linear (6.67 vs. 5.45 vs. 4.68 vs. 5.13 vs. 3.81 ± 0.92% wet-basis). Feeding RPC during feed restriction increased abundance of transcripts involved in choline metabolism ( CHKA , PLD1 ), synthesis of apolipoprotein-B100 ( APOB100 ), and antioxidant activity ( GPX3 ), and decreased the abundance of transcripts involved in hepatic lipogenesis ( DGAT2 , SREBF1 ) and acute phase response ( SAA3 ). Most effects were linear with amount of choline fed. Changes in hepatic mRNA abundance followed a pattern of reduced lipogenesis and enhanced lipids export, which help explain the reduced hepatic triacylglycerol content in cows fed RPC. Choline exerts lipotropic effects in dairy cows by altering transcript pathways linked to hepatic lipids metabolism.

Fracture energy (Gf) studies provide us with means to assess the variation in ductility of concrete. This paper presents the results of fracture energy studies conducted on 18 mixes of M60 Grade concrete consisting of rubcrete (0%, 5%, 10%, 15% of crumb rubber), steel fibre reinforced rubcrete (0.25%, 0.5%, 0.75%, 1% steel fibres and 0% and 15% crumb rubber) and polypropylene fibre reinforced rubcrete (0.1%, 0.2%, 0.3% polypropylene fibres and 0% and 15% crumb rubber) using three-point bend beam tests on 60 × 100 × 500 mm specimens as per TC 50 FMC (1985). Results indicated an enhancement of fracture energy with an increase in rubber content.

Identifying sources of variance that contribute to residual feed intake (RFI) can aid in improving feed efficiency. The objectives of this study were to investigate immune cells phenotype and bioenergetic measures in CD4 + T cells in low feed efficient (LE) and high feed efficient (HE) dairy cows. Sixty-four Holstein cows were enrolled at 93 ± 22 days in milk (DIM) and monitored for 7 weeks to measure RFI. Cows with the highest RFI (LE; n = 14) or lowest RFI (HE; n = 14) were selected to determine immune cells phenotype using flow cytometry. Blood was sampled in the same LE and HE cows at 234 ± 22 DIM to isolate peripheral blood mononuclear cells, followed by magnetic separation of CD4 + T lymphocytes using bovine specific monoclonal antibodies. The metabolic function of isolated CD4 + T lymphocytes was evaluated under resting and activated states. An increased expression of CD62L + cells within CD8 + T lymphocytes and CD21 + B lymphocytes was observed in HE cows compared to LE cows. CD4 + T lymphocytes of HE cows exhibited an increased mitochondrial and glycolytic activity in resting and activated states compared to LE cows. These data suggest that immune cells in HE cows exhibit an increased metabolic function, which might influence nutrient partitioning and utilization and serve as a source of variation in feed efficiency that warrants future investigation.

PurposeTo describe 5-fluorouracil (5FU) pharmacokinetics, myelotoxicity and respective covariates using a simultaneous nonlinear mixed effect modelling approach.MethodsThirty patients with gastrointestinal cancer received 5FU 650 or 1000 mg/m2/day as 5-day continuous venous infusion (14 of whom also received cisplatin 20 mg/m2/day). 5FU and 5-fluoro-5,6-dihydrouracil (5FUH2) plasma concentrations were described by a pharmacokinetic model using NONMEM. Absolute leukocyte counts were described by a semi-mechanistic myelosuppression model. Covariate relationships were evaluated to explain the possible sources of variability in 5FU pharmacokinetics and pharmacodynamics.ResultsTotal clearance of 5FU correlated with body surface area (BSA). Population estimate for total clearance was 249 L/h. Clearances of 5FU and 5FUH2 fractionally changed by 77%/m2 difference from the median BSA. 5FU central and peripheral volumes of distribution were 5.56 L and 28.5 L, respectively. Estimated 5FUH2 clearance and volume of distribution were 121 L/h and 96.7 L, respectively. Baseline leukocyte count of 6.86 × 109/L, as well as mean leukocyte transit time of 281 h accounting for time delay between proliferating and circulating cells, was estimated. The relationship between 5FU plasma concentrations and absolute leukocyte count was found to be linear. A higher degree of myelosuppression was attributed to combination therapy (slope = 2.82 L/mg) with cisplatin as compared to 5FU monotherapy (slope = 1.17 L/mg).ConclusionsBSA should be taken into account for predicting 5FU exposure. Myelosuppression was influenced by 5FU exposure and concomitant administration of cisplatin.

Wheat ( Triticum aestivum L.) is one of the most significant crops and the backbone of food security worldwide. However, low wheat production remains a substantial concern in global agricultural systems. It can be attributed to several factors, including adverse climatic conditions, plant disease and poor soil quality. Recent efforts have explored bioinoculant applications as a promising approach to enhance wheat yield, trying to mitigate constraints essential for future wheat production and global food security. This study tested talc powder, wheat biochar, sugarcane bagasse biochar, and farmyard manure as carriers with two endophytic bacterial strains, Burkholderia phytofirmans PsJN and Bacillus spp. MN54 was applied to three wheat varieties (Ujala-16, Zincol-16, and Fathejang-16). The data was recorded at the seedling and maturity growth stages of plants. A pot experiment revealed significant improvements in plant growth following bioinoculant application compared to controls. Notably, the combination of sugarcane bagasse biochar with Bacillus sp. MN54 exhibited the most pronounced effects, promoting internodal length, spike length, tiller number per plant, grain yield per plant, and spikelets per spike. Additionally, talc powder with Bacillus sp. MN54 increased peduncle length, tiller number per plant, and spike length in Fathejang-16. These findings offer valuable insights into optimizing bioinoculant formulations for improved agricultural practices, adapting to climate change, and contributing to ensuring global food security.
