Abstract

A deadly and debilitating disease, colorectal cancer (CRC), is rapidly becoming a significant threat to public health. However, current therapeutic approaches are still hampered by various side effects. Due to its benefits and remarkable apoptotic impact on cancer cells, plant-derived flavonoids now garner interest as candidates for cancer therapy. Isoquercitrin, a flavonoid commonly found in fruit plants, especially mangoes, is notable due to its ability to inhibit cancer development through various mechanisms. This review aims to highlight the use of isoquercitrin extracted from mango peels in inhibiting CRC carcinogenesis. A literature search was done on Pubmed, Proquest, and Google Scholar using inclusion and exclusion criteria, and a narrative review was synthesised using the evidence gathered. Validity assessment was done through the the Office of Health Assessment and Translation (OHAT) and Oxford Center for Evidence-Based Medicine (CEBM) critical assessment tools. Evidence suggested that isoquercitrin is promising as adjuvant therapy in CRC. It may inhibit overaccumulation of cytoplasmic β-catenin and its translocation into the nucleus, thus downregulating the expression of target proto-oncogenes leading to carcinogenesis of colon crypts. Isoquercitrin concentration in mango peel is abundant, 557.7 mg/kg in dried mango peel and 31.0 mg/kg in pure extracts. A pharmacology study approved that a daily intake of 5.4 mg/kgBW of isoquercitrin has an effective anticancer effect. This substance has good oral bioavailability and is well-tolerated but inhibits the metabolising enzymes CYP1A1 and CYP1B1. In conclusion, isoquercitrin is a potential adjuvant in inhibiting CRC growth with minimum costs and side effects.

Abstract

The Supreme Court of the Republic of Indonesia issued a Supreme Court Circular Letter (SEMA) Number 2 of 2023 concerning the Prohibition of Registration of Interfaith Marriages. However, the rules reap the pros and cons. Various international agreements on civil, political, economic, social and cultural rights as well as conventions on the elimination of discrimination against women have given men and women the right and freedom to marry without any religious restrictions. The purpose of this writing will be to answer the formulation of the problem, namely to find out the complexity of recording interfaith marriages from a human rights perspective with material for analysis of the Supreme Court Circular Letter Number 2 of 2023. The research method in this paper uses normative law with a statutory and conceptual approach. The results of the research show that there is SEMA No. 2 of 2023 guided by the Marriage Law No. 1 of 1974 (Marriage Law) which has a standard that regulates the complete rejection of the legality of marriage for all religions and beliefs. Even though these various international conventions are contradictory, it needs to be understood that Indonesia has rules regarding marriage which are contained in Law Number 1 of 1974 which should be the main legal rule (lex specialist) in its implementation. Meanwhile, the rules or norms contained in international conventions conflict with Law Number 1 of 1974. Therefore there is no legal problem with the existence of Law No. 1 of 1974 is different from the Universal Declaration of Human Rights as a fundamental instrument of human rights.

Abstract

This article was written based on the discovery that there was waqf land that was originally built as a prayer room. The waqf land was located on a hill. However, the prayer room that had been built was demolished by the waqf's grandson and moved to another location. A house was built on the site of the demolished prayer room. The author used qualitative research methods, employing descriptive methods. The data collection tools were observation, interviews, and documentation. Since this study analyzed the transfer of waqf land functions based on Law No. 41 of 2004, the author used a normative legal and empirical legal approach in this paper. From the research findings, it can be concluded that first, the views of the surrounding community regarding the conversion of waqf land indicate that some members of the community are unaware of the laws governing waqf land. This suggests that the community's understanding of waqf land is still limited, as evidenced by some members of the community converting the function of waqf land. Second, the waqf land was originally built as a mosque. The location of the endowment land is on a hill, but the mosque that had been built was demolished by the endower's grandchild and relocated to another place. The site of the demolished mosque was then built into a house by the endower's grandchild. Third, an analysis of Law No. 41 of 2004 on the conversion of the function of waqf land states that waqf land that has been donated as waqf is prohibited from being changed in status or transferred in any form except through an exchange intended for public interest in accordance with the general spatial plan outlined in Law No. 41 of 2004 on Waqf, Articles 1 and 2.

Abstract

This research aims to understand nikah fasid (invalid marriage) and its implications for iddah (waiting period) from the perspective of the Shafi’i school of thought. When a marriage is declared fasid or invalid, it leads to various legal consequences, including issues related to the status of children, mahram relationships, and one significant aspect—iddah. Iddah is a mandatory waiting period during which a woman is prohibited from remarrying, intended to confirm the emptiness of the womb, as an act of devotion, or as mourning for the deceased husband. Iddah is a prescribed obligation following a valid marriage. In the case of a fasid marriage, the implications differ, and this issue is often overlooked. This study uses a qualitative method with a library research approach and employs descriptive-analytical analysis. The primary data sources are Shafi’i fiqh books, while general fiqh books serve as secondary sources. The findings show that an invalid marriage has no legal effect if no sexual intercourse has occurred. However, if intercourse has taken place within the fasid marriage, iddah becomes obligatory for the woman.

Abstract

This study explores economic neglect as a dimension of domestic violence within Indonesian divorce cases, analyzed through the lens of Fatima Mernissi’s Islamic feminist framework. Mernissi’s framework is particularly relevant in Muslim-majority contexts, as it critically challenges patriarchal interpretations of Islamic legal norms that continue to shape family law adjudication. Using a qualitative design that integrates juridical-normative and socio-legal approaches, the study analyzes 16 divorce decisions issued by five Religious Courts in Indonesia between 2016 and 2025. The findings reveal that economic neglect never occurs in isolation: 100% of cases intersect with other forms of violence, including psychological, physical, and social abuse. Three patterns of economic neglect are identified: total neglect (37.5%), partial neglect (43.75%), and neglect accompanied by economic exploitation (18.75%). However, only 18.75% of the cases culminated in the imposition of full economic sanctions, reflecting the limited enforcement of women’s economic entitlements. Significant regional disparities were also found, with courts in East Java demonstrating greater consistency than those in other regions. The study proposes legal reforms, including explicit recognition of economic neglect as an autonomous form of domestic violence in Article 9 of the Act of the Republic of Indonesia Number 23 of 2004 concerning the Domestic Violence Elimination Law (UU PKDRT) and reformulation of Articles 80 and 84 of the Compilation of Islamic Law (KHI). These reforms are intended to reinforce enforceable post-divorce economic responsibilities, advance substantive justice, and foster greater consistency in judicial practice at the national level.

Abstract

Neprilysin (NEP) is a zinc-dependent metallopeptidase, considered a key therapeutic target in heart failure management. Efficient identification of potent NEP inhibitors remains a challenge in drug discovery. The aim of this study was to develop a quantitative structure–activity relationship (QSAR) model using 2D Mordred molecular descriptors and Random Forest algorithms to predict the inhibitory potency (pIC50) of drug candidates. A curated dataset of compounds with experimentally determined IC₅₀ values (in nM) against NEP was preprocessed and converted to pIC50. Mordred was used to calculate 2D molecular descriptors, and descriptors with missing values were excluded. The dataset was split into training, internal validation, and external test sets. A Random Forest regression model was trained using 500 estimators, and model performance was evaluated using R2, root mean square error (RMSE), mean absolute error (MAE), and concordance correlation coefficient (CCC), while a binary classification model was also constructed. Feature importance, residual analysis, and chemical space visualization were conducted to assess model interpretability and reliability. The regression model demonstrated moderate to strong predictive performance, with R2 of 0.286, RMSE of 0.949, MAE of 0.723, and CCC of 0.532 in the internal validation. External validation showed improved generalization, with R2=0.659, RMSE=0.858, MAE=0.630, and CCC=0.763. Binary classification revealed an accuracy of 0.953, precision of 1.000, recall of 0.943, and an F1-score of 0.971, indicating strong discriminative ability in classifying inhibitory versus non-inhibitory compounds. Top contributing descriptors included ATSC2p (feature importance=0.0505), GATS2p (0.0408), and SaasC (0.0317). Principal component analysis (PCA) and Williams plots confirmed that test compounds lie within the model’s applicability domain, with no major outliers in leverage or residual distribution. The developed Random Forest-based QSAR model demonstrates strong predictive power and interpretability for identifying NEP inhibitors. This study provides a valuable tool for virtual screening and highlights the relevance of 2D structural features in governing NEP inhibitory activity. It is the first dedicated QSAR analysis of neprilysin inhibition using Mordred descriptors with rigorous internal and external validation.
