Abstract

This study investigates the patterns of sperm utilization in female Drosophila melanogaster of the bdp and btx strains through sequential mating with multiple males. The research was conducted as a descriptive observational study without experimental manipulation. Females of each strain were crossed with four different males in a specific order, with a two-day interval between each mating. F1 offspring phenotypes were recorded daily over a six-day period following the final mating. Data were analyzed descriptively and supported by somatic chromosome reconstruction to identify the male origin of each offspring. The results indicate that sperm utilization in D. melanogaster females occurs in both random and non-random patterns. Non-random utilization was observed when offspring were produced exclusively from the first male, with no contribution from subsequent males. For example, in the female btx × male N cross, only N female and N male offspring were produced, indicating that sperm from the first male was preferentially used. In contrast, random sperm utilization was evident in later matings, where offspring from multiple males appeared, suggesting that previously stored sperm remained viable and were used alongside or instead of sperm from later matings. These findings highlight the complexity of post-mating sexual selection in D. melanogaster, particularly the role of female sperm storage and utilization mechanisms. The ability of females to either favor the sperm of a particular male or mix sperm from several males may provide evolutionary advantages in terms of genetic diversity and offspring fitness. This study contributes to a better understanding of reproductive strategies and sperm competition in insects, with potential implications for broader studies in evolutionary biology and genetics.

Abstract

Sepsis is a critical medical condition caused by a systemic immune response to infection and is often associated with severe organ dysfunction and high mortality. Bacterial sepsis, including cases triggered by Escherichia coli, can damage host tissues as the immune response becomes dysregulated. Infections involving E. coli in the digestive tract have become increasingly common. Among the affected organs, the liver plays a key role in metabolic regulation and host defense during sepsis. This study investigated the effect of Paederia foetida L. leaf extract on liver weight in a murine sepsis model. Introducing E. coli induces systemic infection and establishes the sepsis model, a commonly used approach in experimental studies to mimic the clinical features of sepsis. After acclimation, mice received treatments for 14 days across several groups: a normal control (N), a negative control (K–) given distilled water, a positive control (K+) given ciprofloxacin, and three treatment groups receiving P. foetida extract at 100 mg/kg BW (P1), 300 mg/kg BW (P2), and 500 mg/kg BW (P3). The analysis revealed significant differences among groups, with the highest mean liver weight recorded in P1 (1.3750 ± 0.3932). Liver abnormalities included enlargement, increased organ mass, swelling, and thickening of one liver lobe, which may reflect heightened hepatic workload during infection and toxin clearance. Interestingly, the normal group showed greater liver weight than several treatment groups, possibly due to fatty accumulation within hepatic tissue, which can influence overall organ mass.

Abstract

Arctium lappa L. (burdock) root contains phytochemicals—including flavonoids, saponins, and phenolic compounds—reported to exhibit immunomodulatory activity. This study evaluated the safety of Arctium lappa L. root extract through a 28-day post-test experimental design involving male and female Wistar rats. Eight animals were randomized into four groups receiving oral doses of 0, 150, 300, or 450 mg/kg BW/day. Lymphocyte counts were measured using an automated analyzer, and splenic histopathology was assessed on Hematoxylin–Eosin–stained sections using semiquantitative scoring. Lymphocyte values (mean ± SD) showed no significant differences among groups (p > 0.05; small effect size) and remained within physiological limits, with males ranging from 4.14 ± 0.21 to 7.96 ± 0.34 ×10³/µL and females from 2.04 ± 0.18 to 15.43 ± 0.52 ×10³/µL. No necrotic lesions were identified in any dose group. Splenic congestion and extramedullary hematopoiesis were mild to moderate, remaining below 30–50% involvement without architectural disruption. These findings indicated that repeated oral exposure to A. lappa extract up to 450 mg/kg BW/day did not induce structural injury or suppress immune-cell profiles, supporting its preliminary safety for further toxicological and immunopharmacological investigation.
