The present study was carried out to determine the efficacy of the apex preservation technique in the management of benign prostatic hyperplasia (BPH) complications following surgery.For this purpose, the PubMed, Embase and Cochrane Library electronic databases were widely searched for controlled trials published up to 2025.The ROBINS-I tool was used to assess the risk of bias in the included studies.Funnel plots and Egger's regression test were applied for publication bias in the present study.GRADEpro was used to assess the quality of evidence.The results revealed that the surgery duration of the preserving technique was significantly shorter [mean difference (MD), -9.82; 95% confidence interval (CI), -13.91 to -5.73; P<0.00001].The preserving technique method was associated with a lower incontinence rate (relative risk, 0.18; 95% CI, 0.07 to 0.46; P=0.0004).Blood loss in the preserving technique group was also less (MD, -65.37; 95% CI, -121.97 to -8.77; P=0.02).On the whole, as demonstrated herein, preserving the prostatic apex is also more time-efficient, leading to a markedly lower risk of developing complications such as blood loss and quicker urinary continence recovery following catheter removal.This leads to improved patient satisfaction, while maintaining similar International Prostate Symptom Score, quality of life and peak urinary flow rate values.Therefore, further research is required in order to fully determine the clinical effects of prostatic apex preservation in BPH surgery in minimizing the rate of complications.

Garcinia atroviridis (GA) is widely used in Southeast Asia, but its anticancer potential is less studied than that of other Garcinia species. This work aimed to investigate the flavonoid constituents of GA and their molecular mechanisms against lung cancer using an integrated systems pharmacology and experimental approach. Phytochemical profiling was performed by LC–HRMS, and flavonoid-associated targets were predicted using SwissTargetPrediction. Lung cancer–related genes were collected from GSE19188 and GeneCards, with overlapping targets identified through Venn analysis. Protein–protein interaction (PPI) analysis defined hub genes, while molecular docking and dynamics simulations assessed ligand–target interactions. Finally, cytotoxicity of the GA ethanolic extract was evaluated in A549, H460, and BEAS-2B cells after 72 h treatment. Our investigation revealed the presence of 5 major flavonoids, including icariin. Network analysis revealed 142 overlapping targets, with SRC, HSP90AA1, CTNNB1, PIK3R1, and AKT1 emerging as hubs. Docking showed strong binding affinities, particularly between quercetin-3β-D-glucoside and SRC, which was confirmed by stable molecular dynamics simulations. In vitro, GA extract reduced the viability of A549 and H460 cells with lower IC₅₀ values than in BEAS-2B. GA exerts selective anticancer effects against lung cancer primarily through targeting SRC, with supportive modulation of HSP90AA1, CTNNB1, PIK3R1, and AKT1. These findings position SRC as the key mechanistic anchor and highlight GA as a promising source for multi-targeted cancer therapy.

The identity crisis experienced by the nation of Judah during the Babylonian exile represents a profound challenge to faith and religious identity. The cultural pressure of Babylon, expressed through the changing of names, the imposition of unclean food, and the demand to worship foreign gods, threatened the continuity of the people’s covenant relationship with God. This study aims to analyze the identity crisis of the nation of Judah in the Book of Daniel and to explore its relevance for contemporary Christians who face the influence of globalization, technological advancement, social media, and secular culture. The research employs a qualitative, historical approach, using secondary data from biblical commentaries, theological journals, and scholarly articles obtained through Google Scholar. The results show that the steadfast faith of Daniel and his companions serves as a timeless model for Christians to maintain spiritual integrity amid modern pressures. Strengthening spiritual discipline, fostering faith communities, and applying pastoral counseling are essential strategies to preserve Christian identity in the age of globalization.

Abstract This study aims to describe the GBI Antiokhia Medan congregation's understanding of the doctrine of God's grace and examine how this understanding is relevant to their spiritual growth. This study employed a qualitative, descriptive-phenomenological approach through in-depth interviews with several GBI AM congregation members. Two biblical texts form the the theological foundation of the study : Ephesians 2:1-10 and Romans 5:1-11, which emphasize that salvation is received solely by God’s grace. The findings indicate that, in general, the congregation understands grace as an undeserved gift from God. However, some members still tend to associate it with human efforts to "repay" that grace through good deeds. Analysis from a Reformed-Evangelical theological perspective highlights that a proper understanding of grace fosters a humble, grateful, and Christ-centered spirituality. Based on these findings, the study recommends that spiritual formation programs at GBI Anthiokia Medan emphasize grace as the foundation principle for the congregation's spiritual growth. Keywords: grace; spiritual growth; Reformed-Evangelical; Ephesians 2; Romans 5. Abstrak Penelitian ini bertujuan untuk mendeskripsikan pemahaman jemaat GBI Antiokhia Medan terhadap doktrin kasih karunia Allah dan menelaah bagaimana pemahaman tersebut relevan terhadapa pertumbuhan rohani mereka. Penelitian ini menggunakan pendekatan kualitatif deskriptif-fenomenologis melalui wawanara mendalam dengan sejumlah jemaat GBI AM. Dua teks Alkitab yang menjadi dasar teologis penelitian adalah Efesus 2:1-10 dan Roma 5:1-11, yang menekankan bahwa keselamatan adalah anugerah semata. Hasil penelitian menunjukkan bahwa secara umum jemaat memahami kasih karunia sebagai pemberian Allah yang tidak layak diterima. Namun sebagian anggota masih cenderung mengaitkannya dengan usaha manusia untuk “membalas” kasih karunia dengan perbuatan baik. Analisis dari perspektif teologi Reformed-Injili menegaskan bahwa pemahaman kasih karunia yang benar melahirkan spiritualitas yang rendah hati, penuh rasa syukur, dan berpusat pada Kristus. Penelitian ini merekomendasikan agar pembinaan rohani di GBI Antiokhia Medan menekankan kasih karunia sebagai fondasi utama dalam pertumbuhan rohani jemaat. Kata Kunci: kasih karunia; pertumbuhan rohani; Reformed-Injili; Efesus 2; Roma 5

This study investigates the development of biodegradable nonwoven fabrics utilizing Alpinia purpurata pseudo-stem fibres, bonded with poly lactic acid (PLA) through a thermal bonding process. Given the underutilization of Alpinia purpurata fibres, this research explores their potential for sustainable textile applications. The fibres were extracted via decortication and blended with PLA at varying mass ratios (90/10, 80/20, 70/30), followed by comprehensive characterization. Evaluations included fabric mass per unit area, thickness, air permeability, tensile strength, elongation, wetting time, moisture regain and surface morphology. The results indicate that increasing PLA content enhances tensile strength but reduces air permeability and water absorption. Conversely, a higher proportion of Alpinia purpurata fibres improves breathability and moisture regain. These findings demonstrate that Alpinia purpurata fibres, in combination with PLA, can produce nonwoven fabrics with tunable properties, offering promising potential for environmentally friendly textile applications.

Background: Optimal breast milk production meets infants’ nutritional needs, crucial in stunting prevention. Many postpartum mothers face insufficient milk production, which can affect infant weight gain and increase the risk of stunting. The innovation of combining oxytocin massage with Foxy Oil is expected to enhance breast milk volume, frequency of wet diapers, and infant weight gain—key indicators in stunting prevention. Methods: This study used a quasi-experimental design with purposive sampling, involving 60 postpartum mothers: 30 in the intervention group and 30 in the control group. Statistical analyses were conducted using SPSS 26 for univariate and bivariate data. Data normality was tested using the Kolmogorov-Smirnov test and bivariate analysis with the Mann-Whitney test. Breastfeeding optimisation was assessed based on breast milk volume, number of wet diapers, and infant weight over one month in the working area of Tanjung Morawa Community Health Centre. The husband or a close family member performed an Oxytocin massage twice daily for 10–15 minutes. Results: Bivariate analysis after oxytocin massage showed significant effects on breast milk volume (p = 0.000), number of wet diapers (p = 0.000), and infant weight (p = 0.039). The analysis indicates that the combination of Foxy Oil and oxytocin massage positively affects breast milk production, frequency of wet diapers, and infant weight gain. Conclusion: Foxy Oil's innovation, combined with oxytocin massage, can be widely applied in midwifery practice to support successful exclusive breastfeeding and contribute to stunting prevention.

This study systematically reviews existing literature on job-crafting in organizational settings over the past decade. It examines the impact of job crafting on employee and organizational performance, explores internal and external influencing factors, and identifies research gaps. Additionally, it develops a conceptual framework illustrating job crafting’s determinants and outcomes, offering recommendations for future research and practical applications. A systematic literature review (SLR) was conducted using the PRISMA framework to ensure a rigorous selection process. The review focused on Scopus-indexed peer-reviewed articles published between 2013 and 2023. A multi-stage filtering process narrowed the dataset, ultimately selecting 13 highly cited studies for in-depth analysis. Job crafting enhances job satisfaction, employee well-being, and organizational commitment. Key internal factors include self-efficacy, motivation, and job autonomy, while external factors such as social support and leadership styles also play crucial roles. However, barriers such as high job demands, role ambiguity, and lack of organizational support limit its effectiveness. Despite its benefits, research on practical interventions and implementation strategies remains scarce. This study synthesizes insights from high-impact literature to provide a structured framework for future research. It emphasizes the need for empirical studies on job-crafting interventions across different industries and work environments.
