Antrodia cinnamomea is a Taiwanese medicinal mushroom with high antioxidant and polysaccharide content. The objective of this study is to investigate developmental toxicity of A. cinnamomea in pregnant Sprague-Dawley rats. Animals were daily gavaged with A. cinnamomea mycelium at dosage levels of 0 (reverse osmosis water), 50, 150, and 500 mg/kg from gestation day (GD) 6 to 15. All dams were sacrificed on GD 20 and were subjected to cesarean section. Fetuses were examined for external, visceral, and skeletal abnormalities. All copulated females survived until the end of the study. No significant differences were recorded in body weight change, food consumption, and maternal gestational parameters. Only two fetal malformations were noted in 970 fetuses from the treatment groups. Some variations, such as enlarged fontanel, split sternebrae, absent sacral, absent caudal vertebral centra, absent thoracic centra, absent 13th-14th ribs, and fused ribs, were found during the skeletal examination, but no treatment-induced abnormalities occurred. No dose dependency was observed in any of the developmental variations. Overall observation of foetal malformations from rats given A. cinnamomea mycelium during pregnancy demonstrates that this material is not teratogenic at doses up to 500 mg/kg. It is concluded that A. cinnamomea BCRC 35398 mycelium has no teratogenic effects in female rats and is safe to be used as a functional food ingredient.

Background: Endocrine-disrupting chemicals (EDCs) interfere with the endocrine system and negatively impact reproductive health. Biochanin A (BCA), an isoflavone with anti-inflammatory and estrogen-like properties, has been identified as one such EDC. This study investigates the effects of BCA on transcription, metabolism, and hormone regulation in primary human granulosa cells (GCs), with a specific focus on the activation of bitter taste receptors (TAS2Rs).

In order to investigate the causes of population degradation and resource decline, this thesis investigated the ecotoxicological effects of heavy metal Cu(Ⅱ) on the embryonic development of Sepiella maindroni. Results indicate significant effects of Cu(Ⅱ) concentrations on the developmental toxicity, teratogenicity, and lethality of S. maindroni embryos.

Background/objectives: Water-soluble vitamins, comprising the B-complex vitamins and vitamin C, are essential for normal growth, cellular metabolism, and immune function in pediatric populations. Due to limited storage in the body, these vitamins require consistent intake to prevent deficiencies. Pediatric populations, particularly infants and young children, face a heightened risk of both deficiency and, in rare cases, toxicity due to varying dietary intake and increased developmental needs.

Amphotericin B (AmB) is a commonly utilized antifungal agent, which is also recommended for the treatment of certain neglected tropical diseases, including leishmaniasis. However, its clinical application is constrained because of its poor oral bioavailability and adverse effects, prompting the investigation of alternative drug delivery systems. Polymeric nanoparticles (PNPs) have gained attention as a potential drug delivery vehicle, providing advantages such as sustained release and enhanced bioavailability, and could have potential as AmB carriers.
