Obesity increases the risk of various diseases. Black rice, renowned for its high anthocyanin content, is considered a potential functional food for preventing metabolic disorders. The current study investigated the effects of black rice crunch (BRC) on body weight and haematological profiles in obese rats. Rats were fed with high-fat diet to induce obesity and supplemented with different concentrations of BRC for 4 and 8 weeks. The results showed that high-fat diet effectively induced obesity, as evidenced by significant increase in body weight. Importantly, 75% BRC supplementation resulted in significant weight reduction in obese rats. Further analysis revealed an increase in erythrocyte numbers in obese groups supplemented with 75% BRC, but no significant changes in haemoglobin concentration or haematocrit percentage. Further investigation showed that 75% BRC led to a decrease in mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), and mean corpuscular volume (MCV), potentially affecting the size and concentration of haemoglobin within erythrocytes. The total leucocytes count increased with the high-fat diet, while BRC supplementation alone did not have significant impact. Lymphocyte percentage remained stable across the groups, indicating minimal influence of the dietary interventions. Neutrophil percentage varied initially but was not specific to BRC or the high-fat diet. Platelet count and distribution width were not significantly influenced, but mean platelet volume (MPV) increased after 8 weeks of BRC treatment, suggesting larger platelet sizes associated with obesity. Overall, the study provides important insights into the effects of BRC supplementation on body weight and haematological parameters related to obesity.

Coronavirus Disease-19 (COVID-19) is a disease caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), this disease began to emerge at the end of 2019 and has become a pandemic to this day. Vaccination can play an important role to prevent the spread of the disease, so there are many vaccine developments, including DNA vaccines. Delivery systems such as chitosan can increase the effectiveness of vaccines. The purpose of this study was to optimize and evaluate the pEGFP-N1-S1 formula with a chitosan delivery system as a DNA vaccine candidate. Plasmids were cloned in E.coli DH5Î± and extracted for further evaluation with restriction enzymes and sequencing. The EGFP-N1-S1 plasmid was then formulated with chitosan nanoparticles with a mass ratio of Plasmid DNA:chitosan of 1:0.1; 1:0.2; 1:0.3; 1:0.4; 1:0.5; 1:0.6 and 1:0.7. The isolated plasmid has a concentration of 2182.32 ng/L and a purity of 1.911. Restriction results showed that the S1 gene (684 bp) was successfully inserted into the pEGFP-N1 plasmid (4813 bp). DNA:chitosan mass ratio of 1:0.6 is the optimal formulation for DNA to bind with chitosan perfectly.

Electro Capacitive Cancer Therapy (ECCT) is an electric field-based cancer therapy method using intermediate frequency (150 kHz) and low intensity (18 Vpp). High Mobility Group Box 1 (HMGB1) is a cytokine related to damage-associated molecular patterns (DAMPs) secreted by dead cells. The expression of Programmed Death Ligand 1 (PD-L1) is ligand present on the surface of tumor cells and its expression is associated with the increase in the number CD8+ T lymphocytes. This study aims to examine the effect of ECCT exposure on the expression of HMGB1 and PD-L1 genes on the breast tumor, brain, and liver tissues of Rattus norvegicus (Berkenhout, 1769). The tissues were obtained from the previous studies stored in RNAlater (-20˚C). Female rat tissues of the previous study from four treatment groups, namely the control group (NINT), non-DMBA-induction with therapy (NIT), DMBA-induction with non-therapy (INT), and DMBA-induction with therapy (IT). Gene expression was analyzed using the RT-qPCR. Statistical t-test with a p<0.05 significance level was performed using GraphPad Prism 9.4.0 software. The result shows HMGB1 and PD-L1 mRNA genes were both significantly expressed in breast tumor samples. The liver and brain samples of normal rats did not show any significant changes in the activity of these genes after exposure to the electric field. This study indicates that exposure to electric fields may trigger the expression of HMGB1 and PD-L on the rat’s breast tumor samples. This study also provides information related to the safety of ECCT in healthy organs of female rats, especially the brain and liver.Keywords: ECCT, breast tumor, HMGB1, PD-L1, IFN- γ.

Pemberian pakan eksogen awal merupakan hal yang penting dilakukan dalam kegiatan pembenihan ikan laut, termasuk ikan kerapu macan (Epinephelus fuscoguttatus). Peralihan dari pakan endogen ke pakan eksogen merupakan fase kritis bagi kelangsungan hidup larva ikan kerapu macan pada stadia awal. Keberadaan pakan eksogen dapat berpengaruh terhadap aktivitas enzim pencernaan dan pertumbuhan larva. Penelitian ini bertujuan untuk mengevaluasi peranan pakan eksogen awal terhadap aktivitas enzim pencernaan dan pertumbuhan larva stadia awal. Dua perlakuan yang diujicobakan adalah larva diberi pakan eksogen dan larva tidak diberi pakan eksogen. Pakan eksogen awal yang diberikan berupa zooplankton rotifer Brachionus rotundiformis. Parameter yang diamati adalah aktivitas enzim pencernaan yang meliputi protease, amilase dan lipase; penyerapan pakan endogen; dan pertumbuhan larva yang meliputi panjang total dan bobot tubuh. Hasil penelitian menunjukkan bahwa aktivitas enzim pencernaan larva umur 3 hari yang tidak diberi pakan awal adalah lebih tinggi dibandingkan dengan larva yang diberi pakan eksogen awal. Pakan endogen habis terserap pada larva umur 3 hari. Panjang total larva pada kedua perlakuan adalah cenderung sama, sedangkan bobot tubuh pada larva yang diberi pakan awal lebih besar dibandingkan yang tidak diberi pakan. Hasil penelitian ini menunjukkan bahwa pemberian pakan eksogen awal berpengaruh terhadap aktivitas enzim pencernaan dan pertumbuhan larva ikan kerapu macan pada stadia awal.

Jembrana disease, caused by the Jembrana virus, leads to high mortality (30%) and abortion (49%) in cattle, making vaccination essential. In this study, a multiepitope vaccine was designed using immunogenic TM and CA proteins. Predicted cytotoxic T lymphocyte, helper T lymphocyte, and linear B-cell epitopes were linked with flexible linkers, and the 50S L7/L12 ribosomal protein was added as a TLR4 agonist. In silico analysis confirmed the construct as non-allergenic, antigenic, and thermostable (aliphatic index 85.44), with 94.2% of residues in favored Ramachandran regions. Docking analysis revealed strong binding to TLR4 (−66 kcal/mol), and molecular dynamics simulations validated the structural stability. Immune simulations revealed increased antigen and antibody levels (IgM early, IgG1/IgG2 after day 15), progressive CD4+ T-helper expansion, transient CD8+ T-cell peaks, elevated IFN-γ and IL-2, and strong dendritic cell activation through MHC I and II pathways. These findings indicate the vaccine effectively stimulates humoral and cellular responses, supporting its potential as a promising candidate against the Jembrana virus.

Breast cancer is the most common cancer that causes death in women in the world. Cancer development is facilitated by the inhibition of apoptosis and induction of angiogenesis. Current cancer therapy still encounters problems in the form of recurrence, resistance, and side effects of drugs. Non-contact static electric field therapy, electro capacity cancer therapy (ECCT) with medium frequency, is a therapy developed to inhibit the proliferation of tumor cells. This study aimed to determine the mRNA expression of p53, Apaf-1, survivin related to apoptosis and NF-κB, bFGF and TSP-1 related to angiogenesis in rat breast tumor tissue after ECCT frequency of 150 kHz. Breast tissue samples and rat breast tumor nodules stored in RNA later at -20°C were used. The tissue was obtained from the non-induction non-therapy (NINT) group, induction non-therapy (INT), non-induction therapy (NIT), and induction therapy (IT). mRNA expression of p53, Apaf-1, NF-κB, bFGF and TSP-1 were analyzed using qRT-PCR and calculated with the Livak formula. Data were analyzed using one-way Anova and post-hoc LSD. The results showed that, mRNA expression of p53, Apaf-1 and TSP-1 in the IT group increased significantly, and mRNA expression of survivin and bFGF decreased significantly compared to the INT group. However, the expression of NF-κB mRNA in the IT group remained the same as in the INT group. In conclusion, ECCT with a frequency of 150 kHz upregulates p53, Apaf-1 and TSP-1 mRNA expression and downregulates survivin and bFGF mRNA expression but have no effect on NF-κB mRNA expression in rat breast tumor tissue.

Breast cancer remains one of the most prevalent malignancies worldwide. The use of combinations of natural products is increasingly recognized as a promising strategy for cancer treatment. Turmeric rhizome (Curcuma longa L.) and soursop leaves (Annona muricata L.) are two natural materials known for their anticancer potential. This study aimed to identify the phytochemical constituents of turmeric rhizome and soursop leaf extracts and to evaluate the anticancer activity of their combination against T47D breast cancer cells. Turmeric and soursop leaves were extracted with 96% ethanol using the maceration method. Raw material standardization was performed by measuring water content, ethanol-soluble content, and water-soluble content. The extract was standardized by thin-layer chromatography. T47D and Vero cell lines were used in this study. Compound identification was performed using Liquid Chromatography–Quadrupole Time-of-Flight Mass Spectrometry (LC/Q-TOF-MS). The candidate combination ratio was determined using the simplex lattice design approach in Design Expert 13 software. Cytotoxicity and antiproliferative effects were assessed using the MTT assay, while antimetastatic potential was evaluated through the scratch assay. Apoptosis and cell cycle arrest were analyzed by flow cytometry. IC_50 data were analyzed using one-way ANOVA, and post hoc testing was performed using Tukey’s multiple-comparison test. Antiproliferation and scratch assay data were analyzed using two-way ANOVA followed by the Bonferroni test. Apoptosis and cell cycle assay data were analyzed using one-way ANOVA followed by the Tukey post hoc test. Phytochemical profiling indicated the existence of fifteen chemicals in both turmeric rhizome and soursop leaf extracts. The candidate combination ratio of turmeric rhizome to soursop leaf extracts was 1:21, exhibiting cytotoxic activity with an IC50 value of 32.2 ± 2.5 ug/mL. The combined extract was associated with antiproliferative, anti-migratory, and pro-apoptotic responses and induced G2/M phase cell cycle arrest in T47D cells.
