Abstract

Objectives
Pain affects about one in every five persons and is considered a major global health burden. Hyphaene thebaica (Arecaceae), is a medicinal plant used in Cameroon, fruit pulp are macerated and orally administered in traditional medicine to treat various ailments, including hypertension, pain, and inflammation. This study aimed to evaluate the pain-killing effect of fruit pulp extracts of H. thebaica in mice.

Methods
Aqueous (AEHT) and methanol (MEHT) extracts were prepared from fruit pulp of H. thebaica, followed by a qualitative phytochemical analysis. The extracts were given orally at doses of 100, 200, and 400 mg/kg in acute pain models such as acetic acid, formalin, hotplate, and capsaicin. Control groups included distilled water (negative), and diclofenac, morphine, ruthenium red, diazepam (positive). Naloxone pretreatment was used to assess opioid pathway involvement. Locomotor and sedative effects were evaluated using rota-rod and open-field tests. Acute toxicity was assessed at 2,000 mg/kg.

Results
Phytochemical tests revealed saponins, flavonoids, tannins, and phenols. Both extracts greatly decreased the writhing induced by acetic acid. MEHT inhibited both phases of formalin-induced pain (p<0.01). Both extracts significantly inhibited hotplate-induced nociception (p<0.001), partially reversed by naloxone, except for MEHT. In the capsaicin test, extracts produced a remarkable reduction of paw licking time (p<0.01). No motor coordination alteration or acute toxicity effects were observed.

Conclusions
The findings demonstrated the analgesic activity of AEHT and MEHT, mediated by the stimulation of opioids and blockage of vanilloid receptors pathways.
Experimental investigation on bacterial concrete by using Cantabro loss and UPV
Authors: Syed Riyaz , Pollayi Hemaraju 
Published: February 2025

Abstract
The use of bacterial concrete has become popular as a way to fix fractures in a variety of constructions, including pavements, pipelines, canal linings, bridges, and reinforced concrete buildings. Concrete constructions frequently have cracks that let water and other chemicals in, weakening the structure and compromising reinforcement. Henk Jonkers came up with the idea of bacterial concrete to solve this issue. Concrete cracks were sealed experimentally using calcium lactate and Bacillus subtilis. The bacteria that were chosen were those that could thrive in alkaline conditions. M20 and M40-grade concrete mixes substituted river sand and crushed stone sand for fine aggregate with varying proportions of B. subtilis and calcium lactate. At various curing ages, the study looked at how bacteria affected abrasion resistance. For various mixtures, empirical relationships were proposed between various concrete properties and bacterial content.

Authors: Duan Xue 
Published: February 2025

Abstract
Due to the complexity and dynamism of animated scenes, frame prediction in animated videos is a challenging task. In order to improve the playback frame rate of animated videos, an innovative convolutional neural network combined with convolutional gated recursive unit method is used to refine the synthesized stream in frame prediction of animated videos. The obtained results indicated that the average prediction accuracy of the proposed model was 99.64%, and the training effect was good. The peak signal-to-noise ratios on the three datasets were 31.26, 36.63, and 22.15 dB, respectively, and the structural similarities were 0.958, 0.886, and 0.813, respectively. The maximum Learned Perceptual Image Patch Similarity of the proposed model was 0.144. This indicates that the model has achieved excellent performance in prediction accuracy and visual quality, which can successfully capture complex dynamics and fine details in animated scenes. The contribution of this study is to provide a technical support for improving the accuracy of frame prediction in animated videos, which will help promote the intelligent development of the animation production field.
Stochastic improved Simpson for solving nonlinear fractional-order systems using product integration rules
Authors: Fareed Aisha F. , Semary Mourad S. 
Published: February 2025

Abstract
This research introduces a novel and robust numerical approach, the stochastic improved Simpson Method, specifically developed to solve Itô and Stratonovich stochastic nonlinear system of differential equations with fractional order. By extending the classical Simpson’s one-third rule with the explicit product integration rectangle rule, the proposed method efficiently handles fractional derivatives of orders between 0 and 1, based on the Caputo derivative. The novelty of this approach lies in its enhanced accuracy and stability in addressing the unique challenges posed by both Itô and Stratonovich systems, outperforming traditional numerical techniques. Rigorous order analysis, conducted with Mathematica 12 software, demonstrates the robustness and precision of the method. Its effectiveness is further validated through four distinct numerical case studies, highlighting its superior performance in solving stochastic nonlinear system of differential equations with fractional order.
Continua and orientations of packing-repacking and unpacking ideational metaphor for knowledge construction
Authors: Zhou Nana 
Published: February 2025

Abstract
This article constructs the multidimensional paradigm to specify the continuum of ideational metaphor by virtue of metaphoricity. Metaphoricity is redefined as a relative term measured by the amount of grammatical metaphor and the rank-shift to delineate the continuum of metaphorization. As an expression is packed and repacked by ideational metaphor, its semantic density increases in implicitness. But its context-dependency declines since ideational metaphor smashes its iconic relation with the reality, which to a certain extent weakens semantic gravity. The orientation towards the nucleus can be instantiated to illustrate the direction of metaphorization. In contrast, as a metaphorical expression is unpacked, its semantic density decreases by releasing the inter-stratal tension between grammar and semantics. Its context-dependency strengthens by rebuilding its iconicity with the reality, which reinforces semantic gravity. An element with the lower nuclearity to Center may be unpacked at the initial stage. This article provides an academic lens for knowledge construction in English teaching and learning.

Authors: Major Josh , Wild Klaire , Elfar Annes , Dennis Brody , Oldham Eli , Hagood Alex , Paul Eli , Checketts Jake X. , Ford Alicia Ito , Vassar Matt 
Published: February 2025

Background:
Orthopaedic surgery is a critical field, impacting global health-care expenditure and patient outcomes. Despite substantial research funding, issues of transparency and reproducibility persist, undermining the credibility of published in-print findings. Data-sharing initiatives aim to address these challenges by promoting accessibility and enhancing research reliability. We aimed to assess the landscape of data-sharing practices within the field of orthopaedic surgery, focusing on the top orthopaedic journals from 2020 to 2023.

Methods:
Original research articles from 10 of the top orthopaedic journals were screened and analyzed for data-sharing statements (DSSs). Furthermore, we identified variables that were influential on the inclusion of DSSs in orthopaedic clinical studies, and thematically analyzed DSS content to identify prevalent themes. Lastly, corresponding authors were contacted to assess their willingness to share their data.

Results:
Of the 1,084 reviewed articles, only 14% included a DSS. The Journal of Bone & Joint Surgery demonstrated the highest proportion of articles with a DSS. Over time, clinical trials exhibited an increasing trend in DSS adoption, contrasting with consistently low rates among cohort studies. Thematic analysis identified the gatekeeper role and conditional data availability as predominant themes in orthopaedic DSSs. Of the 115 emails sent to corresponding authors, only 22 (19.1%) yielded responses, and of those who responded, only 12 (54.5%) expressed a willingness to share their data.

Conclusions:
Our findings underscore a substantial disparity in data-sharing practices across orthopaedic journals, highlighting the need for standardization and mandates for DSSs. Adopting the Transparency and Openness Promotion (TOP) Guidelines can enhance accountability and foster a culture of open science within the field. By addressing these shortcomings, orthopaedic journals can improve research reproducibility and advance scientific knowledge effectively.
Pinpointing Amazon forest tipping in global warming and deforestation pathways

Published: February 2025

Abstract

Humanity is putting unprecedented pressures on the Amazon forest systems due to global warming, deforestation, land-use change as well as large-scale infrastructure projects. Since the Amazon forest may possess a tipping point beyond which detrimental changes are self-propelling, these pressures could lead to system-wide state changes across major parts of the Amazon forest. We apply a dynamical systems model to assess the tipping risks and cascading transitions in the Amazon forest systems under different shared socio-economic emission and land-use change pathways (SSPs). For these emission scenarios, we constructed the according atmospheric moisture transports within the Amazon forest using a state-of-the-art moisture tracking model. Without deforestation, we find a critical threshold of 3.7-4.0°C of global warming where adaptive capacities of the forest may be surpassed such that around a third of the Amazon forest loses stability. However, when taking into account deforestation, our simulations robustly find a near system-wide tipping point of the Amazon forest (62-77% of the area) between 1.5-1.9°C of global warming and deforestation between 22-28%. These are values that humanity may reach already within the first half of this century, and possibly as early as in the 2030ies. Importantly, the large majority of the observed tipping events in our model (87-99%) are caused by knock-on effects from increasing drought intensities, leading to long-ranging and self-propelling cascading effects on scales of hundreds to thousands of kilometres. Overall, our results underscore the necessity to keep global warming to below 1.5°C as well as stop deforestation (around 15%) and restore these areas to avoid high tipping risks across the Amazon forest.
Do pilot free trade zones promote green transformation? Evidence from a quasi-natural experiment
Authors: Sun Yanan , Jiang Luyao , Hu Yuru , Yang Jie 
Published: February 2025

Abstract

With institutional innovation as its core mission, pilot free trade zones are important channels that accelerate the green transformation of enterprises, a process essential for achieving sustainable development. Based on a quasi-natural experiment of pilot free trade zone policies, this research selects panel data of China’s A-share listed companies from 2008 to 2022 to empirically test the impact of these policies on the firms’ green transformation by using a multi-period difference-in-differences method. The findings show that pilot free trade zone policies significantly promote their green transformation. An effect test notes that these policies affect enterprises’ green transformation via financing constraints and green innovation level. Heterogeneity test results present that compared to enterprises and state-owned enterprises (SOEs) in the central and west regions, the green transformation effect of these policies on enterprises and non-SOEs in the east region is more significant. This paper offers valuable policy suggestions for promoting high-quality development of pilot free trade zones and guiding enterprises’ green transformation that contributes to sustainable and socially responsible growth.
Ultrasound Insights: Necrotic Choroidal Melanoma Presenting as Neovascular Glaucoma and intraocular inflammation
Authors: Yang Ye , Wu Xishi , Fang Wei 
Published: February 2025

Abstract

This report describes a case of necrotic choroidal melanoma in a 69-year-old woman presenting with neovascular glaucoma (NVG) and intraocular inflammation. Ultrasonographic evaluation, including B-scan and color Doppler imaging, revealed vitreous opacities, intraocular calcifications, necrotic areas without intralesional blood flow, and vascular bud-like signals at the scleral wall. These ultrasonographic findings provided critical diagnostic clues, distinguishing the condition from inflammatory intraocular diseases. Histopathology confirmed necrotic choroidal melanoma with over 50% necrosis and no evidence of orbital invasion. This case underscores the importance of ultrasonography in identifying necrotic choroidal melanoma presenting with NVG and inflammation.
Comparison of Ethanol-Iohexol Mixture and Ethanol-Lipiodol Suspension in Rabbit Renal Artery Embolization
Authors: Zhou Zijun , Jiang Hua , Liu Zhenyin , Zhang Jing , Li Haibo 
Published: February 2025

Abstract

Objective
To evaluate the efficacy and safety of an ethanol-iohexol mixture (EIM) as an endovascular embolic agent using a rabbit renal artery embolization model.
Methods
Thirty rabbits were randomly assigned to the EIM group or the ethanol-lipiodol suspension (ELS) group. Each rabbit underwent renal artery catheterization, followed by embolization with 1 mL of either EIM or ELS. Digital subtraction angiography (DSA) was performed immediately and five minutes post-embolization to assess vascular occlusion. Liver and kidney function tests were conducted at multiple time points (day 3, week 1, and week 2 post-embolization) to evaluate safety. After two weeks, the rabbits were sacrificed, and kidney specimens were collected for histopathological examination.
Results
Both EIM and ELS achieved effective and sustained vascular occlusion without evidence of collateral artery formation or recanalization. EIM was easier to inject and spread rapidly, whereas ELS, due to its higher viscosity, was more difficult to administer and separated within one minute. DSA imaging confirmed faster visualization of the embolization effect in the EIM group. Histopathological analysis confirmed thrombosis in the renal arteries of both groups, with no significant difference in the timing of occlusion. Liver function markers (ALT, AST) and kidney function markers (BUN, UA, β2-MG, Cystatin C) exhibited transient elevations post-embolization but returned to baseline over time.
Conclusions
Both EIM and ELS demonstrated effective and sustained renal artery embolization without recanalization. EIM, as a water-soluble, non-separating mixture, was easier to inject and provided rapid embolization, whereas ELS, with its higher viscosity, required greater injection force and exhibited phase separation. Despite differences in handling properties, both embolic agents achieved comparable vascular occlusion, with transient and reversible changes in liver and kidney function, indicating acceptable safety profiles.
