Abstract

The decreasing of sensitivity or resistance to tamoxifen occured after long-term treatment in breast cancer. One of the major factor in tamoxifen resistance is over expression of efflux transporter P-glycoprotein (P-gp) and Breast Cancer Resistance Protein (BCRP). Curcumin has known as inhibitor of P-gp and BCRP. The addition of curcumin to the tamoxifen resistant cells is expected to increase the sensitivity of breast cancer cells to tamoxifen. This study aim to know the effect of curcumin in increasing the cell sensitivity to tamoxifen through inhibition of P-gp and BCRP transporter efflux. MCF-7 breast cancer cell line was induced with tamoxifen 1 µM for 10 passage (MCF-7(T)), then cell viability and mRNA expression of P-gp and BCRP were analyzed. To the MCF-7(T) cells, curcumin was given at of 5/10/20 µM with or without tamoxifen for 5 days and cell viability and mRNA expression of P-gp and BCRP were analyzed on day 5th. As positive control, verapamil 50 µM was used as P-gp inhibitor, ritonavir 15 µM and nelfinavir 15 µM were used as BCRP inhibitor. The results showed that MCF-7(T) cells sensitivity to tamoxifen decreased with 11.8 times, the cell viability increased 10.82 fold and mRNA expression of P-gp and BCRP increased 4.04 fold. Then after administration of curcumin with or without tamoxifen for 5 days, the cell viability and the mRNA expression of P-gp and BCRP decreased. As conclusion, curcumin increased the sensitivity of MCF-7(T) to tamoxifen characterized by the decreasing of cell viability and mRNA expression of P-gp and BCRP. However, the administration of combination of curcumin with tamoxifen was more potent than just curcumin. The increased sensitivity was estimated at least partly through the inhibition of P-gp and BCRP mRNA expression by curcumin

Abstract

Objective: This is to compare peripheral and central serum levels of Anti-Mullerian hormone (AMH) in experimental animals for predicting ovarian reserve. Methods: This is an experimental study involving 20 female Sprague-Dawley rats aged 8–10 weeks with normal estrus cycles as the young control group and 5 female rats aged 28–30 weeks as the old control group (n = 5/group): the young control group, the old control group, the 1x cisplatin group, the 2x cisplatin group, and the 3x cisplatin group. After treatment, tissue collection, histological staining, and blood collection through the retro-orbital bleeding (ROB) and heart were performed. Subsequently, measurements of ovarian weight, follicle counting, and levels of AMH and Follicle-stimulating hormone (FSH) were conducted.Results: The serum AMH levels from ROB in the young control, 1x cisplatin, 2x cisplatin, 3x cisplatin, and the old control groups were 1151, 1818, 2782.96, 1381.352, and 1544 ng/mL, respectively. Cisplatin 2x group was significantly (p<0.005) higher compared to the young control. The average concentrations of serum AMH in the ROB and heart were higher in the 2x cisplatin group compared to the other groups. Meanwhile, cisplatin 3x group decreased in level due to the burn out phenomenon. Conclusion: AMH is a preferred marker compared to FSH. Blood collection through the ROB is considered a less invasive alternative technique in the treatment group, requiring serial observation. Keywords: AMH, follicle pool, ovarian aging, ROB

Abstract

Uremic cardiomyopathy is the leading cause of death in patients with chronic kidney disease. Fluid overload and oxidative stress play important roles in its pathogenesis. This study aims to determine the effect of quercetin on uremic cardiomyopathy in 5/6-nephrectomized rats. To our knowledge, its cardioprotective effect on uremic cardiomyopathy induced in rats by 5/6 nephrectomy has not been investigated yet. Uremia was induced surgically in male Sprague-Dawley rats via 5/6 nephrectomy. Quercetin was administered per orally at a dose of 100 mg/kg/day for 8 weeks prior to sacrifice. Meanwhile, captopril was administered at a dose of 10 mg/kg/day. Lipid peroxidation was assessed using TBARS reaction, while GPX activity was determined to explore the endogen antioxidant mechanism. Myocardial fibrosis was analyzed using Massons’ Trichrome staining and the level of NT-proBNP in plasma was measured as a marker of cardiac dysfunction. Nephrectomy 5/6 had no effects on plasma NT– proBNP levels, cardiac and plasma MDA levels, but induced mild myocardial fibrosis and significant increase in cardiac GPX activity in comparison with normal rat (p<0.05). However, administration of quercetin or captopril did not ameleriote those mild myocardial fibrosis and increased GPX activity. Uremic cardiomyopathy induced by 5/6 nephrectomy demonstrated mild myocardial fibrosis but preservation of cardiac function demonstrated by NT-proBNP levels. Increased of GPX activity in the nephrectomized-rats compared to the control rats (p<0.05) suggests induction of antioxidant defense mechanisms that might not be exhausted yet. This condition highlighted a compensatory phase which was unchanged following chronic administration of either quercetin or captopril.

Abstract

Background: In cases of alkali burn, blood serum eyedrops may supply protein and growth factors. A standard preparation protocol is necessary for consistency in epitheliotropic capacity. Objective: We aim to evaluate how post-alkali-burn administration of blood serum eyedrops from different preparation protocols results in different outcomes on rabbits. Methods: This randomized experimental study used three treatments: placebo, non-diluted serum, and 25% concentration serum. We analyzed the corneal haziness, neovascularization degree, histopathological examination of neovascularization scores, and alpha-smooth muscle actin (α-SMA) expression. Results: Twelve rabbits (24 eyes) were split evenly into three treatment groups. On day 14, the group receiving the 25% concentration serum had the least corneal haziness (p = 0.005). No adverse effect was observed on the treated eyes. Histopathologically, no significant difference in neovascularization scores and α-SMA expression was observed. Conclusions: Treatment using the 25% concentration serum resulted in less corneal haziness, smaller defect size, and greater healing rate. There was also no significant difference in histopathological outcomes among the three treatment groups.

Abstract

Plant-derived exosome-like nanoparticles (PDELNs) represent a promising frontier in nanomedicine, offering natural alternatives to synthetic drug delivery systems. These membrane-bound vesicles, typically 30-150 nm in size, contain bioactive compounds and demonstrate potential for cross-kingdom communication with mammalian cells. This objective study is to evaluate PEG-based and ultracentrifugation methods, benchmark hybrid approaches, compare emerging alternatives, and assess their impact on biomedical applications. A systematic analysis of diverse studies employing comparative yield, purity, bioactivity, scalability, and complexity metrics was conducted. A systematic search of 3 databases SciSpace Deep Search; Google Scholar; MEDLINE (2016-2024) following PRISMA guidelines, 52 studies met the inclusion criteria with combined terms : ``plant exosome'' AND (``PEG precipitation'' OR ``polyethylene glycol'' OR ``ultracentrifugation'' OR ``hybrid methods'') AND ``biomedical applications''. Findings indicate that PEG-based precipitation offers higher or comparable yields with greater scalability and cost-effectiveness but lower purity due to protein co-precipitation; ultracentrifugation yields purer exosomes with preserved bioactivity yet is resource-intensive and less scalable; hybrid methods combining PEG precipitation with ultracentrifugation or size-exclusion chromatography balance yield and purity while increasing procedural complexity. Emerging techniques, such as immunoaffinity capture, enhance specificity but face limitations in plant systems. Overall, optimized hybrid protocols improve isolation quality and bioactivity retention, supporting translational potential. These insights underscore the need for standardized, scalable isolation strategies tailored to plant exosomes to advance their clinical and biomedical applications.

Abstract

This study aims to analyze the relationship between physicians’ knowledge of informed consent and the completeness of its implementation in medical procedures. The research employed an observational analytic approach with a cross-sectional design and quantitative methods. The study population consisted of general practitioners, specialists, dentists, and dental specialists working at Banten Provincial General Hospital and Dr. Drajat Prawiranegara Regional General Hospital. A total of 94 physicians were included as respondents. The variables examined included physicians’ knowledge of informed consent, the completeness of its implementation, and respondent characteristics such as age, years of service, and training history. Data were analyzed using the chi-square test with a significance level of p < 0.05. The results indicated a significant association between physicians’ knowledge, years of service, and prior training with the completeness of informed consent implementation. Physicians with good knowledge demonstrated a higher likelihood of complete implementation (OR 10.6; 95% CI 3.7–30.4) compared to those with poorer knowledge. Similarly, physicians with less than five years of service had a higher rate of complete informed consent implementation (78%) compared to those with five or more years of service (57.1%). Moreover, those who had received training were significantly more likely to implement informed consent completely (OR 6.95; 95% CI 1.51-31.94) than those without training experience. In contrast, physician age was not significantly associated with informed consent completeness. In conclusion, enhancing physician knowledge and promoting ongoing training are essential to improving the quality of informed consent practices in clinical settings.
