    The purpose of this study was to assess local diagnostic reference levels (LDRLs) for full-field digital mammography (FFDM) and digital breast tomosynthesis (DBT) mammography in India. Data from 1500 women were collected from five different mammography facilities in major cities in Tamil Nadu, India. The mean of mean glandular dose were used to arrive at an LDRL. The noted mean compressed breast thickness was 55.26 ± 3.4. The recorded mean MGDs for the five centres were 3.1 ± 0.1 and 3.8 ± 0.2 mGy for FFDM and DBT, respectively. The 75th percentile value for all five centers is 3.3 and 4.0 mGy for FFDM and DBT, respectively. The LDRLs found in the current study were also compared with those from earlier studies conducted in other nations, such as the United Kingdom, Malaysia, Morocco, and Ghana. The present study is the first of its kind to determine the LDRL for the FFDM and DBT scanners operating in the Tamil Nadu region, India, and is proposed as a starting point that will allow professionals to evaluate and optimize their practice. Furthermore, similar studies in other regions of India are necessary in order to establish National DRLs.

    Colorectal cancer (CRC) remains a leading cause of death globally despite the improvements in cancer treatment. Autophagy is an evolutionarily conserved lysosomal-dependent degradation pathway that is critical in maintaining cellular homeostasis. However, in cancer, autophagy may have conflicting functions in preventing early tumour formation versus the maintenance of advanced-stage tumours. Defective autophagy has a broad and dynamic effect not just on cancer cells, but also on the tumour microenvironment which influences tumour progression and response to treatment. To add to the layer of complexity, somatic mutations in CRC including tumour protein p53 (TP53), v-raf murine sarcoma viral oncogene homolog B1 (BRAF), Kirsten rat sarcoma viral oncogene homolog (KRAS), and phosphatase and tensin homolog (PTEN) can render chemoresistance by promoting a pro-survival advantage through autophagy. Recent studies have also reported autophagy-related cell deaths that are distinct from classical autophagy by employing parts of the autophagic machinery, which impacts strategies for autophagy regulation in cancer therapy. This review discusses the molecular processes of autophagy in the evolution of CRC and its role in the tumour microenvironment, as well as prospective therapeutic methods based on autophagy suppression or promotion. It also highlights clinical trials using autophagy modulators for treating CRC, underscoring the importance of autophagy regulation in CRC therapy.

    The color of skin lesions is a crucial diagnostic feature for identifying malignant melanoma and other skin diseases. Typical colors associated with melanocytic lesions include tan, brown, black, red, white, and blue-gray. This study introduces a novel feature: the number of colors present in lesions, which can indicate the severity of skin diseases and help distinguish melanomas from benign lesions. We propose a color histogram analysis, a traditional image processing technique, to analyze the pixels of skin lesions from three publicly available datasets: PH2, ISIC2016, and Med-Node, which include dermoscopic and non-dermoscopic images. While the PH2 dataset contains ground truth about skin lesion colors, the ISIC2016 and Med-Node datasets lack such annotations; our algorithm establishes this ground truth using the color histogram analysis based on the PH2 dataset. We then design and train a 19-layer Convolutional Neural Network (CNN) with different skip connections of residual blocks to classify lesions into three categories based on the number of colors present. The DeepDream algorithm is utilized to visualize the learned features of different layers, and multiple configurations of the proposed CNN are tested, achieving the highest weighted F1-score of 75.00 % on the test set. LIME is subsequently applied to identify the most important features influencing the model's decision-making. The findings demonstrate that the number of colors in lesions is a significant feature for describing skin conditions. The proposed CNN, particularly with three skip connections, shows strong potential for clinical application in diagnosing melanoma, supporting its use alongside traditional diagnostic methods.

    Indonesia generates approximately 7.8 million tons of plastic waste annually, which 4.9 million tons is mismanaged. Presently, there is significant concern on microplastics (MPs) pollution in aquatic environment. The research on the prevalence of MPs in river systems are comparatively lower than the studies conducted on marine systems. The primary goal of this research was to look into the prevalence of MPs in the river water of Mahakam of Tenggarong City, Indonesia. To adequately represent this area, a meticulous selection method was used to find five separate sampling locations, with two stations at each location, positioned 200 m apart on opposite sides of the river. According to the study's findings, MPs has been observed in the range of 19.2 ± 1.8 to 58.5 ± 3.5 particles/l. Based on the MPs type, fragments (43.4 %) were the most common type of MPs found in water samples. Furthermore, 44.6 % of the MPs had size smaller than 1000 μm. The prevalent hues observed in the water samples were transparent and black, composing 75.6 % of overall formation. The determination of microplastic polymers employed Attenuated Total Reflection-Fourier Transform Infrared (ATR-FTIR) spectroscopy, revealing the presence of various type, such as polyethylene (PE) and polypropylene (PP).

    Current alcohol-based sanitizers present safety concerns and are not suitable for all applications. To address the issue, biopolymer hydrogels offer a safer, sustainable alternative due to biocompatibility, biodegradability, and customizable properties. In present study, carboxymethyl cellulose (CMC) was prepared from Durian fruit rind, a tropical fruit byproduct rich in polysaccharides and combined with the synthetic polymer Carbopol to form a hydrogel with homogenization technique. Rambutan (Nephelium lappaceum) leaf extract (RLE) as an antibacterial agent was analyzed for functional, morphological, antibacterial, and structural properties. Phytochemical analysis of RLE confirmed the presence of antibacterial compounds, while Minimum Inhibitory Concentrations (MIC) were 33.3 μg/mL for Escherichia coli and 28.5 μg/mL for Staphylococcus aureus. Additionally, Scanning Electron Microscopy showed significant disruptions in bacterial cell walls. Hydrogel incorporated RLE was produced with improved properties confirmed through viscosity, FT-IR, Disc-diffusion assay and spread plate method analysis. In general, Rambutan leaf extract significantly improves the antibacterial properties of biopolymer-based hydrogels, hence offering a promising, eco-friendly alternative to alcohol-based sanitizers.

    To mitigate adverse effects of ocean warming on coral reef degradation, resource managers increasingly explore management and regulation of local stressors to strengthen coral resilience and recovery. Comprehensive assessments and monitoring efforts offer a holistic understanding of reef dynamic ecosystems. In this study, we documented the distribution of benthic foraminiferal assemblages surrounding Pulau Redang, Malaysia, and assessed their potential for monitoring coral reef health using the Foraminifera in Reef Assessment and Monitoring (FoRAM) Index. Undeveloped (R1-R3) and developed (R4-R6) reef sites revealed distinct differences in reef conditions. Foraminiferal distribution showed Amphistegina lessonii (14-34%) as the dominant species, followed by Calcarina hispida (21%) and Calcarina mayori (19%). The Q-mode cluster analysis classified the distribution of foraminiferal assemblages in Pulau Redang into four sub-groups based on the reef ecological conditions. Group A1 and A2, represent the foraminiferal assemblage on the undeveloped west side of the island where live coral cover was >30%. Meanwhile, Group B1 and B2 represent the assemblage found in developed coastal regions with low live coral cover (≤20%). Additionally, the CCA results revealed a substantial influence of substrate type on the distribution of benthic foraminifera in the reef environments of Pulau Redang. FoRAM index consistently yielded high values across the study area despite varying coral reef conditions, probably due to the prevalence of Calcarina mayori in mesotrophic reefs (R4-R6), potentially distorting FoRAM values and providing a misleading indicator of reef conditions. The Modified Foram Index (MFI), calculated by excluding calcarinids, classified R3, R4, and R6 as less conducive for reef growth, aligning better with observed reef conditions. We recommend calibrating the FoRAM Index, particularly in mesotrophic reefs where calcarinids dominate foraminiferal assemblages, to enhance its precision and reliability for coral reef health monitoring and assessment within the region.

    The microwave brain imaging (MBI) system is an emerging technology used to detect brain tumors in their early stages. Multi-class microwave-based brain tumor (MBT) identification and classification are crucial due to the tumor's patterns and shape. Manual identification and categorization of the tumors from the images by physicians is a challenging task and consumes more time. Recently, to overcome these issues, the deep transfer learning (DTL) technique has been used to classify brain tumors efficiently. This paper proposes a Fine-tuned Feature Extracted Deep Transfer Learning Model called FT-FEDTL for multi-class MBT classification purposes. The main objective of this work is to suggest a better pathway for brain tumor diagnosis by designing an efficient DTL model that automatically identifies and categorizes the MBT images. The InceptionV3 architecture is utilized as a base for feature extraction in the proposed FT-FEDTL model. Thereafter, a fine-tuning method is applied to the additional five layers with hyperparameters. The fine-tuned layers are attached to the base model to enhance classification performance. The MBT data are collected from two sources and balanced by augmentation techniques to create a total of 4200 balanced datasets. Later, 80 % images are used for training, 20 % images are utilized for validation, and 80 samples of each class are used for testing the FT-FEDTL model for classifying tumors into six classes. We evaluated and compared the FT-FEDTL model with the three traditional non-CNN and seven pretrained models by applying an imbalanced and balanced dataset. The proposed model showed superior classification performance compared to other models for the balanced dataset. It attained an overall accuracy, recall, precision, specificity, and Fscore of 99.65 %, 99.16 %, 99.48 %, 99.10 %, and 99.23 %, respectively. The experimental outcomes ensure that the proposed model can be employed in biomedical applications to assist radiologists for multi-class MBT image classification purposes. The Anaconda distribution platform with Python 3.7 on the Windows 11 OS is used to implement the models.

    Non-alcoholic fatty liver disease (NAFLD) is one of the most common chronic metabolic liver diseases worldwide. Perillaldehyde (4-propyl-1-en-2-ylcyclohexene-1-aldehyde, PA) is a terpenoid compound extracted from Perilla, which has effective pharmacological activities such as anti-inflammatory, antidepressant, and anticancer. This study aimed to explore the pharmacological effects of PA in intervening with NAFLD and reveal its potential mechanisms. Firstly, we identified the core targets of PA intervention therapy for NAFLD through network pharmacology and molecular docking techniques. After that, in vitro animal experiments such as H&E and Masson staining, immunofluorescence, immunohistochemistry, and Western blot were conducted to validate the results network effectively pharmacology predicted. Network pharmacology analysis suggested that PPAR-α may be the core target of PA intervention in NAFLD. H&E and Masson staining showed that after low-dose (50 mg/kg) PA administration, there was a noticeable improvement in fat deposition in the livers of NAFLD mice, and liver tissue fibrosis was alleviated. Immunohistochemical and immunofluorescence analysis showed that low dose (50 mg/kg) PA could reduce hepatocyte apoptosis, decrease the content of pro-apoptosis protein Bax, and increase the expression of anti-apoptosis protein Bcl-2 in NAFLD mice. Western blot results confirmed that low-dose (50 mg/kg) PA could increase the expression of PPAR-α and inhibit the expression of NF-κB in NAFLD mice. Our study indicated that PA could enhance the activity of PPAR-α and reduce the level of NF-κB in NAFLD mice, which may positively affect the prevention of NAFLD.

    BACKGROUND: Chronic urticaria (CU), in both inducible and spontaneous forms, is associated with a substantial burden in the Asia-Pacific region (APAC). Patient-centred care recognises patients desire to be involved in decisions regarding their health. Although patient-centred approaches have previously not been studied in the context of CU management, they have demonstrated benefits in the management of other chronic conditions.

    METHODS: Information and opinions regarding the barriers and solutions to the implementation of patient-centred approaches to the management of CU were gathered from a group of 13 expert dermatologists and allergist/immunologists from APAC through surveys and a face-to-face meeting.

    RESULTS: Barriers identified there included a lack of awareness of CU amongst patients, delays in consulting healthcare providers, financial constraints, and low adherence. Particular issues raised included a lack of suitable online information for patients (83% of experts), and patients accessing oral corticosteroids without a prescription. Compliance issues were also identified as key reasons for inadequate responses to treatments (67% of experts). Solutions proposed by the authors were improving patients' knowledge about their condition (92% strongly agree, 8% agree), physicians' consideration of patient characteristics when choosing treatments (92% strongly agree, 8% agree), implementing shared decision-making (85% strongly agree, 15% agree), and using patient-reported outcome measures (70% strongly agree, 23% agree).

    CONCLUSION: Expert opinion within APAC supports the use of patient-centred approaches to improve the management of CU. We provide several recommendations focusing on patient education and involvement in disease management as well as disease monitoring methods that can be implemented by physicians in APAC.

    BACKGROUND: Breastfeeding for the first six months and complementary feeding until twelve months are crucial for child growth. A mother's knowledge, attitude, and practice (KAP) on infant feeding significantly impact infant development.

    OBJECTIVE: To assess mothers' KAP toward breastfeeding and complementary feeding.

    METHODOLOGY: A cross-sectional study of 200 mothers with 18- to 24-month-old children at six suburban health clinics in Malaysia. Data were collected via a self-explanatory questionnaire and analyzed using descriptive statistics, chi-square, and Spearman's Rho.

    RESULTS: Most mothers had good KAP: 72.5 % had good knowledge, 75.5 % had a positive attitude, and 87 % had good practice. Factors such as maternal age (30-39), multiparity, and vaginal delivery were associated with KAP. Significant positive correlations were found between knowledge and attitude (r = 0.591) and attitude and practice (r = 0.525).

    CONCLUSIONS: Continued education on breastfeeding and complementary feeding is essential for improving infant feeding practice, and enhancing child development, potentially reducing healthcare costs.

    Ectoparasites cause serious problems during the aquaculture production of food fishes. In this study, we set out to develop and test protocols for maintenance and sampling European catfish (Silurus glanis L., 1758) stocks infected with a gill monogenean, Thaparocleidus vistulensis (Siwak 1932) Lim 1996. When we compared the feasibility of two cohabitation-based parasite culture systems (i.e., static vs. flow-through), we found that the life cycle of T. vistulensis was completed in both habitats. In our experience, static tank systems with regular water exchange allowed better daily quality control of the parasite culture than continuous flow-through systems. We investigated the microhabitat preference of T. vistulensis on the gills of infected European catfish. A balanced distribution on the two lateral gill sets and a decreasing trend in parasite numbers from anterior gill holobranches towards the posterior ones was observed. Using these results, we developed a minimally invasive sampling protocol to estimate the parasite load of individuals. The biopsy aimed at four sectors (#6, #7, #10, and #11) situated within the distal and middle zones of the first holobranch on the left side, encompassing both rows of filaments. Biopsy-based estimates of parasite loads were validated by comparing them to full parasite counts of the same individuals and showed statistically significant correlations. Our biopsy-based method is designed to identify experimental animals with similar parasite loads and create groups of hosts with comparable burdens. This setup is expected to generate reduced between-group differences for expensive experiments (e.g., high throughput transcriptomic or epigenetic studies). We propose that the biopsy-based pre-sorting procedure should be considered in similar experiments with other cultured fish species and their gill monogeneans following a thorough fine-tuning of the experimental conditions.

    BACKGROUND: The fungus comb is a unique structure inside termites' nests that facilitates the growth of Termitomyces sp. as a nutrient source for the termites. It is known to possess immunomodulatory properties that boost the immune system.

    AIM: The objective of this study was to assess the impact of ethyl acetate extract of fungus comb (EAEFC) on the inflammatory reaction in the spleen of mice induced by intraperitoneal injection of lipopolysaccharide (LPS).

    METHODS: An experimental study was conducted using a post-test-only control group design with male BALB/C mice (n = 24). The mice were divided randomly into four groups, each comprising six mice, and administered substances via gavage. Groups I and III were administered a solution of 5% dimethyl sulfoxide (DMSO) in distilled water, while Groups II and IV were given 500 mg/kg BW EAEFC dissolved in 5% DMSO. On the fifteenth day, Groups I and II received intraperitoneal injections of 5 ml/kg BW saline, while Groups III and IV were injected with 10 mg/kg BW LPS dissolved in saline. After three hours, the mice were euthanized and splenic immunohistology was examined under a light microscope. The results were expressed as mean ± standard deviation, while the group differences were assessed statistically.

    RESULTS: The expression of interleukin (IL)-1, furin, and activated NK cell was significantly higher in the inflamed model after EAEFC supplementation, while the extract suppressed IL-10.

    CONCLUSION: EAEFC was found to alter cytokine expression in the spleen in response to inflammation.

    BACKGROUND: Consumer awareness of food adulteration is increasing nowadays. Motivated by economic gain, unethical meat producers try to blend halal meat such as beef with non-halal meat like rat meat (RM).

    AIM: This study aims to develop a real-time polymerase chain reaction (RT-PCR) analysis method to analyze the presence of RM in beef meatballs.

    METHODS: This research was carried out in the following stages: primer design, DNA isolation, analysis of DNA isolates, the optimization of primer annealing temperature, primer specificity test, sensitivity, and repeatability. The validated RT-PCR method was then used to analyze the marketed meatball samples.

    RESULTS: The result showed that the designed primer targeting on ND2 gene set rat mt-DNA (forward: ACTCCATATCTCTCACCATATTTCC; reverse: GGGTTAGGGTACTTAGGATTGTTAG), had good specificity at an optimal annealing temperature of 56.3oC over the other eight species. The developed RT-PCR method produces a limit detection value of 195.31 pg, coefficient of determination (R 2) for linearity of 0.983, amplification efficiency (E) of 100%, and CV value for amplification response of 1.8%. The result showed that the developed RT-PCR method did not detect the presence of RM DNA in eight marketed beef meatball samples.

    CONCLUSION: The developed method meets the acceptance criteria for RT-PCR and can be used as a halal authentication method to identify the presence of RM in beef meatballs.

    BACKGROUND: An intravaginal device (IVD) made from polyethylene plastic and copper wire, integrated with a radio frequency identification (RFID) chip, was developed as a biocompatible contraceptive and identity device for cats.

    AIM: This study evaluates the local and systemic biocompatibility of IVD in five non-pregnant female cats.

    METHODS: The IVD was successfully inserted into the vaginal lumen after estrogen administration. Radiographic imaging confirmed the IVD's position, which lasted up to two days post-insertion.

    RESULTS: Systemic response, assessed through hematological examinations on days 0, 1, and 3 post-insertion, showed no significant changes in erythrogram and leukogram parameters. Local response, evaluated through vulvar inspection and vaginal cytology on days 0, 1, 3, and 7, revealed no neutrophil infiltration in 4 out of 5 cats, indicating compatibility with vaginal tissue. Furthermore, epithelial cell profile changes were observed, showing an increase in superficial cells, which is typical during the estrus phase.

    CONCLUSION: These findings suggest that the IVD is biocompatible and suitable for use as a contraceptive and identity device in cats. However, further long-term studies are necessary to evaluate the device's prolonged efficacy and potential for contraception failure prevention by mating trials.

    STUDY DESIGN: Prospective and retrospective studies.

    OBJECTIVE: The aim of this study was to evaluate the clinical effects and accuracy of three-dimensionally (3D)-printed patient-specific surgical plates used for mandibular defect reconstruction.

    METHODS: This study included patients who underwent mandibular defect reconstruction with vascularized autogenous bone grafts between January 2012 and August 2021. They were divided into experimental (fixation with 3D-printed surgical plates) and control (fixation with conventional surgical plates) groups. Flap survival rate, postoperative complications and patient self-evaluated facial appearance were compared. Mandibular reconstruction accuracy evaluation included postoperative position deviation of the whole mandible, transplanted bone graft, lower mandibular border, mandibular condyle, and mandibular angle on the reconstructed side compared to baseline.

    RESULTS: This study included 20 patients (14 males, six females; age, 39.45 ± 11.69 years), ten each in the experimental and control groups. The mean follow-up was 16 ± 22.05 (range, 6-99) months. All procedures were successful, no plate-related complications (breakage, loosening, or exposure of the surgical plates) were reported, and all patients were satisfied. The groups were statistically similar in th e position deviation of the whole mandible, transplanted bone graft, mandibular condyle, and mandibular angle, but the position and morphology of the lower mandibular border on the reconstructed side in the experimental group were better than those in the control group (P = 0.016).

    CONCLUSIONS: 3D-printed patient-specific surgical plates could be applied in mandibular reconstruction safely and effectively, simplifying the surgical procedure, shortening the preoperative preparation times, achieving satisfactory outcomes, and improving the clinical effects and accuracy of individualized mandibular reconstruction.

    Myocardial infarction (MI), a widespread cardiovascular issue, mainly occurs due to blood clot formation in the coronary arteries, which reduces blood flow to the heart muscle and leads to cell death. Incorporating exercise into a lifestyle can significantly benefit recovery and reduce the risk of future cardiac events for MI patients. Non-coding RNAs (ncRNAs) play various roles in the effects of exercise on myocardial infarction (MI). ncRNAs regulate gene expression, influence cardiac remodeling, angiogenesis, inflammation, oxidative stress, apoptosis, cardioprotection, and cardiac electrophysiology. The expression of specific ncRNAs is altered by exercise, leading to beneficial changes in heart structure, function, and recovery after MI. These ncRNAs modulate molecular pathways that contribute to improved cardiac health, including reducing inflammation, enhancing angiogenesis, promoting cell survival, and mitigating oxidative stress. Furthermore, they are involved in regulating changes in cardiac remodeling, such as hypertrophy and fibrosis, and can influence the electrical properties of the heart, thereby decreasing the risk of arrhythmias. Knowledge on MI has entered a new phase, with investigations of ncRNAs in physical exercise yielding invaluable insights into the impact of this therapeutic modality. This review compiled research on ncRNAs in MI, with an emphasis on their applicability to physical activity.

    Recently, species clustering within Dickeya zeae has been identified as complex, encompassing validly published names, including D. oryzae and D. parazeae, with some strains potentially delineating new species. In this study, genomes of strains isolated from a bacterial heart rot outbreak in pineapple (Ananas comosus var. comosus) on Oahu, Hawaii, along with two strains from pineapple in Malaysia, were sequenced. Orthologous average nucleotide identity (ANI) and digital DNA-DNA hybridization (dDDH) values among the sequenced genomes ranged from 98.93-99.9% and 91.8-99.9%, respectively, supporting the classification of seven strains within the same species. Comparisons of ANI and dDDH values between these seven strains and type strains of D. zeae, D. parazeae, and D. oryzae ranged from 94.4-95.9% and 57.2-66.5%, respectively. These values fall below the proposed boundaries for new species designation, supporting the delineation of a novel species. Phylogenetic analyses, including 16S rRNA, gapA, multi-locus sequence analysis (MLSA) of 10 housekeeping genes, whole-genome, and pangenome analyses, were concordant and revealed a distinct monophyletic clade, separating these strains from other members of the D. zeae complex, with D. oryzae as the closest relative. Notably, a nitrogen fixation gene cluster comprising 28 genes, similar to the Klebsiella spp. nitrogenase gene cluster, was found in the genome of the seven pineapple strains. Based on polyphasic approaches, including ANI, dDDH, biochemical, physiological, and phylogenomic analyses, we propose the reclassification in a new species of the five pineapple strains from Hawaii A5391, A5410T, A5611, A6136, and A6137, together with the two pineapple strains from Malaysia CFBP 1272 and CFBP 1278, previously classified as D. zeae. We propose the name Dickeya ananae sp. nov. for this taxon, represented by the type strain A5410T (= ICMP 25020T = LMG 33197T).

    The number of patients with inflammatory bowel disease (IBD) is increasing worldwide. Since IBD is a chronic disease that seriously affects patients' life quality, preventing and alleviating IBD with natural and less side effect substances has become a research hotspot. Food-derived bioactive peptides have been an attractive research focus due to their high efficiency and low toxicity. This paper comprehensively summarizes food-derived peptides with intestinal health effects, focusing on peptide sequences with IBD-regulatory effects and emphasizing the effects of their structure and physicochemical properties such as peptide length, amino acid composition, and net charge on their function. We also analyzed its regulatory mechanisms, mainly in 5 aspects: modulating the intestinal microbiota, decreasing intestinal epithelial permeability, increasing antioxidant ability, regulating the expression of inflammatory cytokines, and targeting signaling pathways. This review will help establish novel, efficient screening methods for IBD-regulatory peptides and contribute to further research and discovery of them.

    The genomics and genetic information of Malaysian rice (Oryza sativa L.) is currently limited. It was necessary to conduct genome resequencing of these rice accessions exhibiting different responses to salinity stress. The sequencing was carried out using the Illumina NovaSeq X platform with 30× sequencing coverage to pinpoint variants between salinity tolerant and sensitive rice accessions. The discovery of single nucleotide polymorphisms (SNPs) is crucial for the development of DNA markers associated with salinity tolerance traits. The genome sequence data (FASTQ format) for these accessions have been deposited to the European Nucleotide Archive (ENA) database under the accession number PRJEB71716.

    Religious beliefs have a significant impact on consumer preferences, particularly in relation to food choices. Islam, like other religions, imposes specific dietary guidelines, notably regarding meat and meat products. However, ensuring compliance with halal standards across the entire meat and meat products supply chain presents considerable challenges. Instances of non-compliance, including improper slaughtering techniques, mislabeling, adulteration, and contamination, have caused concerns about the authenticity of halal status. To address these concerns, this review explores recent advancements in halal authentication methods and technology, focusing on practical objectives aimed at addressing non-compliance issues. It categorizes methods into four main areas of non-compliance concerns, providing a unique perspective compared to earlier reviews that primarily examined the progression of analytical methods. This classification offers a comprehensive analysis of the field's current status, facilitating the identification of research gaps and strategic recommendations for enhancing future halal authentication methods. Through the implementation of this novel approach, the review seeks to promote the development of a more robust framework for evaluating halal meat and meat products, safeguarding consumer trust and ensuring adherence to religious dietary guidelines in the future.
