Polypoidal Intestinal Metaplasia and Dysplasia of the External Urethral Meatus
Urethral mucosa with intestinal metaplasia and dysplasia is a rare occurrence. To date only a single case has been reported in a male with long-standing urethral stricture. We present a 33-year-old female with polypoid intestinal metaplasia and dysplasia

Instabilities of monolayered epithelia: shape and structure of villi and crypts [PDF]
We study theoretically the shapes of a dividing epithelial monolayer of cells lying on top of an elastic stroma. The negative tension created by cell division provokes a buckling instability at a finite wave vector leading to the formation of periodic arrays of villi and crypts.

Intestinal apoptotic changes linked to metabolic status in fasted and refed rats [PDF]
Intestinal apoptosis and expression of apoptosis inducers - the cytokines TNFalpha, TGFbeta1 - and the intestinal transcription factor Cdx2, were studied according to two different metabolic and hormonal phases which characterize long-term fasting: the long period of protein sparing during which energy expenditure is derived from lipid oxidation (phase

Dynamics of primary cilia in endothelial and mesenchymal cells throughout mouse lung development
Abstract Cilia are specialized structures found on a variety of mammalian cells, with variable roles in the transduction of mechanical and biological signals (by primary cilia, PC), as well as in the generation of fluid flow (by motile cilia). Their critical role in the establishment of a left–right axis in early development is well described, as well ...

Targeting the Tumor Microbiota in Cancer Therapy Basing on Nanomaterials
Intra‐tumoral microbiota, which is a potential component of the tumor microenvironment, has been emerging as a key participant and driving factor in cancer. This article reviews the latest progress in this field, including the microbial community within tumors and its pro‐cancer mechanisms, as well as the anti‐tumor strategies targeting intra‐tumoral ...

Urachal Villous Adenoma Coexistent With Urachal Carcinoma: A Case Report
ABSTRACT Introduction Urinary tract villous adenomas are uncommon, urachal villous adenomas being especially rare. While their malignant potential remains uncertain, villous adenomas may have malignant components. Here, we present a case of the coexistence of a urachal villous adenoma and urachal carcinoma. Case Presentation We report the case of an 86‐

Lower Risk of Gastric Atrophy and Intestinal Metaplasia in Patients with MALT Lymphoma despite Infection [PDF]
Background/Aims Atrophic gastritis and intestinal metaplasia are sequential consequences of chronic Helicobacter pylori (H. pylori) infection. These conditions are well known to increase the risk of gastric adenocarcinoma development.
