Item Metadata only Antifertility effect of sulfanilamide on ultrastructure and motility of epididymal spermatozoa in rats(Mahidol University. Mahidol University Library and Knowledge Center, 2023) Siriwan Prapong; Chumpol Pholpramool; Praset Sobhon; Pawinee Piyachaturawatincreased after SN treatment. Vital staining of the cauda sperm also confirmed this finding. Examination by TEM revealed various lesions of the sperm structure including disruption of the sperm plasma membrane producing free exposure of the outer denseItem Metadata only Purification and characterization of fluorescent probes from blue green algae(Mahidol University. Mahidol University Library and Knowledge Center, 2024) Luckana Laousoontornsiri; Dhirayos Wititsuwannakul; Pichit Tosukhowong. Phycocyanin was found as major components upon disruption of spirulina platensis by repeated freeze-thawing of the cell mass. The blue-green algae is abundant in natural water source and serves as a suitable staring terial. The deep blue supernate afterItem Metadata only Ultrastructural and immunocytochemical studies of the tegument and cytoskeleton of Opisthorchis viverrini(Mahidol University. Mahidol University Library and Knowledge Center, 2023) Wandee Apinhasmit; Prasert Sobhon; Suchart Upatham; Chaitip Wanichanon. The roles of the cytoskeleton are tested by treating adult parasites with colchicine and cytochalasin B. Following a short incugation period (10-20 min), colchicine disrupts some microtubules which, in ture, affect the transport of dense granules fromItem Metadata only Identification of RNA-processing abnormalities of the PKD1 gene in Thai families with autosomal dominant polycystic kidney disease(Mahidol University. Mahidol University Library and Knowledge Center, 2023) Wanna Thongnoppakhun; Prapon Wilairat; Pa-thai Yenchitsomanus; Mathurose Ponglikitmongkol; Chintana Sirinavinthe deletion did not disrupt the donor or acceptor splice site or branch site in this intron. As the result of exon 43 skipping, the translated polycystin-1 would have in-frame deletion of 97 amino acids in the transmembrane (TM) and loop regions, confirming
