Abstract

Background: Smoking cessation lowers blood serotonin levels and triggers withdrawal symptoms such as anxiety. Citrus aromatherapy is known to produce a calming effect through elevated serotonin levels, potentially easing nicotine withdrawal symptoms. Objective: This study aimed to determine the effect of citrus aromatherapy on blood serotonin (5-HT) levels in male Wistar rats undergoing a smoking cessation protocol. Methods: This experimental study used a post-test only control group design with 24 male Wistar rats randomly divided into 4 groups. The normal group received standard feed for 36 days. The negative control, citrus aromatherapy, and fluoxetine groups received standard feed for 7 days, were exposed to cigarette smoke (14 cigarettes/day) for 28 days, then received their respective treatments for 7 days. On day 37, blood was collected to measure serotonin (5-HT) levels using ELISA, and data were analyzed using One Way ANOVA followed by Post Hoc LSD. Results: Mean serotonin (5-HT) levels were 12.70 ± 0.19 ng/ml in the normal group, 5.87 ± 0.23 ng/ml in the negative control group, 10.49 ± 0.22 ng/ml in the citrus aromatherapy group, and 9.88 ± 0.21 ng/ml in the fluoxetine group. All four groups differed significantly from one another (One Way ANOVA, F=1054.890; p<0.001; Post Hoc LSD, p<0.001 for all pairwise comparisons), with the citrus aromatherapy group even surpassing the fluoxetine group. Conclusion: Citrus aromatherapy significantly affected blood serotonin (5-HT) levels in male Wistar rats undergoing a smoking cessation protocol.

Abstract

Background: Mild Cognitive Impairment (MCI) is a transitional stage between normal cognitive aging and dementia that carries a considerable annual risk of progression if left untreated, making early intervention particularly important for institutionalized older adults, who face a higher risk of cognitive decline due to limited activity. Objective: This study aimed to examine the effectiveness of Group Cognitive Stimulation Therapy (GCST) on cognitive function among older adults with MCI in nursing homes. Methods: A quasi-experimental design with a pretest-posttest non-equivalent control group was used, involving 60 older adults (30 intervention, 30 control) recruited through purposive sampling in nursing homes in Semarang between October and December 2024. The intervention group received GCST for 16 sessions over 8 weeks, while the control group continued routine nursing home activities. Cognitive function was assessed using the Montreal Cognitive Assessment (MoCA). Results: Baseline MoCA scores were comparable between groups (21.3 ± 2.4 vs 21.5 ± 2.2; p = 0.728). After the intervention, the mean MoCA score increased to 25.1 ± 2.6 in the intervention group compared with 21.3 ± 2.3 in the control group, a mean difference of 3.8 points (95% CI 2.56-5.04; Cohen’s d = 1.55; p < 0.001). Conclusion: GCST produced a significant and substantial improvement in cognitive function among institutionalized older adults with MCI, supporting its consideration as a low-cost, non-pharmacological component of routine nursing home care, although confirmation through larger, multi-site randomized trials with longer follow-up remains warranted.

Abstract

Background: Alzheimer’s disease (AD) is the leading cause of dementia in older adults, yet early biological confirmation remains challenging in primary care. The plasma amyloid-β42/β40 ratio has emerged as a minimally invasive marker of cerebral amyloid burden. Objective: This study evaluated the diagnostic potential of the plasma amyloid-β42/β40 ratio for early AD detection in elderly primary-care patients and examined its relationship with cognitive performance. Methods: A case-control study was conducted among 20 elderly participants (≥65 years) from community health centres (Puskesmas) in Semarang, Indonesia, including 10 patients with clinically diagnosed AD and 10 age- and sex-matched cognitively healthy controls. Plasma amyloid-β42 and amyloid-β40 were measured using ELISA. Cognitive function was assessed using the MMSE and MoCA. Statistical analyses included independent t-tests, Pearson correlation, ROC analysis, and Firth bias-reduced logistic regression. Results: The plasma amyloid-β42/β40 ratio was significantly lower in the AD group than in controls (0.115 ± 0.005 vs 0.138 ± 0.004; p<0.001), as was amyloid-β42 concentration (35.3 ± 3.1 vs 43.3 ± 2.6 pg/mL; p<0.001). The ratio showed strong correlations with MMSE (r=0.984, p<0.001) and MoCA (r=0.988, p<0.001) scores. ROC analysis demonstrated complete group separation (AUC=1.000) at a cut-off ≤0.126, with 100% sensitivity and specificity. Each 0.01-unit decrease in the ratio was associated with increased AD odds (Firth-adjusted OR=25.79; 95% CI 1.79–372.64; p=0.017). Conclusion: The plasma amyloid-β42/β40 ratio showed strong discrimination between AD and healthy ageing and closely reflected cognitive impairment. However, the small sample size and complete separation require validation in larger, diverse cohorts before clinical implementation.

Abstract

Background: Burns are skin injuries caused by heat exposure that can damage the epidermis, dermis, and even the hypodermis, while also affecting connective tissue, muscle, cutaneous nerves, and blood vessels, thereby disrupting the body's homeostasis. Objective: This study aimed to determine the effect and effective concentration of ethanol extract of skipjack bone (Katsuwonus pelamis) on the epithelialization capacity of burn-induced rats. Methods: Twenty-five rats were divided into five groups: a negative control (KN, distilled water), a positive control (K+, 0.9% NaCl), and three treatment groups (K1, K2, K3) given ethanol extract of skipjack bone at concentrations of 40%, 60%, and 80%. Second-degree burns were induced using a 2 mm iron plate heated to 60°C and applied for 30 seconds on the dorsal skin of the rats. The test preparations were applied topically twice daily for 14 days; erythema score and wound morphology were recorded daily. This was a true experimental study using a pretest-posttest control group design, analyzed using one-way ANOVA and the LSD post-hoc test. Results: One-way ANOVA showed no significant difference in erythema score among the five groups on day 14 (F(4,20) = 0.529; p = 0.716), and the LSD post-hoc test found no significant difference between any pair of groups. Nevertheless, macroscopic observation showed that the 80% concentration group (K3) exhibited earlier scar tissue resolution and epithelial regeneration by day 14 than the 40% and 60% groups. Conclusion: Ethanol extract of skipjack bone showed an indicative effect on the macroscopic appearance of burn wound healing, but did not significantly alter erythema score at the sample size used in this study (n = 5 per group). The 80% concentration showed the most pronounced descriptive trend and warrants further testing with a larger sample size and histopathological examination.

Abstract

Background: Acute respiratory infection (ARI) is a common upper respiratory illness among toddlers, typically starting with fever, cough, nasal congestion, and sore throat, and it can progress to bronchitis, sinusitis, laryngitis, or pneumonia when poorly managed. Aim: This study aimed to examine the effect of peppermint oil inhalation on ARI symptoms in toddlers. Methods: This quantitative study used a one-group pretest-posttest quasi-experimental design without a control group, involving 16 toddlers aged 4 years with non-pneumonia ARI in the working area of Puskesmas Kedungmundu, Semarang. The independent variable was peppermint oil inhalation (3 drops on a dry tissue, twice daily for 5 minutes, over seven consecutive days), while the dependent variable was an ARI symptom score covering four components, cough, nasal congestion, mucus production, and discomfort, rated on a 0-4 scale using an observation sheet. Data were analysed with the Wilcoxon signed-rank test after Shapiro-Wilk testing indicated a non-normal distribution. Results: Symptom scores fell from a pretest median of 2.00 (range 1-4) to a posttest median of 1.00 (range 0-2), a statistically significant reduction (p<0.001); 15 of 16 respondents (93.8%) improved. Conclusion: Peppermint oil inhalation was associated with a reduction in ARI symptoms among 4-year-old toddlers, although the absence of a control group limits causal interpretation and calls for confirmation in more rigorous trial designs.

Abstract

Background: Astaxanthin is a high-value carotenoid with various applications, one of which is in biomedical science. Haematococcus pluvialis is considered the most promising source of natural astaxanthin as it can accumulate up to 5% of its dry weight under stressful conditions. Aim: This narrative review aims to provide a comprehensive synthesis of the biological properties, cultivation challenges, and therapeutic applications of astaxanthin from H. pluvialis in biomedical science. Methods: Articles were collected through searches of the PubMed, ScienceDirect, and Google Scholar databases using combinations of the keywords “astaxanthin,” “Haematococcus pluvialis,” “biomedical,” “cultivation,” and “therapeutic,” prioritising articles published between 2014 and 2024; relevant sources were selected narratively without a formal systematic review protocol. Results: Astaxanthin exhibits neuroprotective, anti-inflammatory, anti-cancer, and cardioprotective effects underpinned by its unique molecular structure and amphiphilic nature. Nevertheless, low bioavailability, high production costs, and the slow growth rate of H. pluvialis remain major obstacles to its clinical translation. Conclusion: Astaxanthin from H. pluvialis represents a multifunctional agent with significant clinical potential, warranting further studies to optimise its bioavailability and therapeutic efficacy.

Abstract

Background: Tea (Camellia sinensis) contains caffeine that is widely used in the beverage, food, and pharmaceutical industries, making the selection of an appropriate isolation method essential for obtaining caffeine with optimal yield and purity. Aim: This study aimed to isolate and purify caffeine from tea leaves using two extraction methods, soxhletation and boiling, and to compare the yield and purity of caffeine produced by each method. Methods: Caffeine was extracted through two pathways: soxhletation with an ethanol-water solvent (70:30 v/v) for 6 hours and boiling with distilled water for 90 minutes, followed by chloroform solvent extraction for the boiling filtrate, then crystallization and recrystallization. Purity was assessed by how closely the melting point of the crystals matched the literature value for pure caffeine. Results: The boiling method produced a yield of 0.38% with a melting point of 235°C, close to the literature value (234–236°C), while the soxhletation method produced a yield of 0.008% with a melting point of 210°C. Crystals from the boiling method were white-green, whereas those from soxhletation were orange-brown. Conclusion: The boiling method proved superior to soxhletation in both yield and purity of the caffeine obtained, making it the more suitable choice for caffeine isolation from tea leaves under the conditions of this study.
