High throughput sequencing of 16S ribosomal RNA gene amplicons is a cost-effective method for characterization of oral bacterial communities. However, before undertaking large-scale studies, it is necessary to understand the technique-associated limitations and intrinsic variability of the oral ecosystem. In this work we evaluated bias in species(More)
Tissue recombinants of embryonic urogenital sinus mesenchyme (UGM) and epithelium of the urinary bladder (urothelium, BLE) of adult rats and mice were grown for 3-30 d in male syngeneic hosts. Short-term in vivo growth indicated that prostatic morphogenesis is initiated as focal outgrowths from the basal aspect of the adult urothelium. The solid epithelial(More)
Prostatic abscess is a rarely described condition and is commonly caused by gram-negative organisms such as enterobacteria. However, as the prevalence of methicillin resistant Staphylococcus aureus (MRSA) increases in the community, unusual infections due to this organism have been recently published. In this report, we describe a patient with diabetes(More)
Tissue recombinants prepared with epithelium of the urinary bladder of adult mice and mesenchyme of the embryonic urogenital sinus were grown as renal capsular grafts in adult male hosts. Under these conditions the bladder epithelium, which is derived embryologically from the urogenital sinus, was induced to form prostate-like acini. The relevance of this(More)
Mesenchyme of the embryonic urogenital sinus induces epithelium of the embryonic urinary bladder to form prostatic acini. The induced glandular epithelium exhibits nuclear androgen-binding sites, as demonstrated autoradiographically. This suggests that the expression of androgen receptor activity in an epithelium is dependent upon the mesenchyme with which(More)
DEVELOPMENT OF THE MAMMALIAN RETINOFUGAL PATHWAYS Sun On Chan, St. John's College, Oxford Submitted for the degree of Doctor of Philosophy (Trinity Term, 1991) The retinofugal pathways in the rat and the ferret have been studied in order to understand how the decussation pattern at the chiasm and the retinotopic maps in the targets are developed. By using(More)
