The relative tissue selectivity of pulsed field ablation (PFA) allows for the safe delivery lesions even when in close proximity to collateral tissues such as esophagus and phrenic nerve. Frequent coughing spells during PFA left atrium can be frequently seen clinical procedures; there is little insight into mechanism effects on bronchi. To assess effect bronchus swine. Microsecond pulses were d...

There is no satisfactory biomarker yet available for predicting the likelihood of premalignant changes or carcinoma developing in Barrett's or columnar lined oesophagus. In this study we have evaluated the proliferation of squamous epithelium, columnar epithelium from columnar lined oesophagus and gastric columnar epithelium from 23 Barrett's patients using positive immunoreactivity with the mo...

PURPOSE Neosquamous epithelium (NSE) can arise within Barrett's esophagus as a consequence of medical or surgical acid reduction therapy, as well as after endoscopic ablation. Morphologic studies have suggested that NSE can develop from adjacent squamous epithelium, submucosal gland ducts, or multipotent progenitor cell(s) that can give rise to either squamous or Barrett's epithelium, depending...

Proper physiological function of mammalian airways requires the differentiation basal stem cells into secretory or multiciliated cells, among others. In addition, self-renewal ability these is crucial for developing a quick response to toxic agents in order re-establish epithelial barrier airways. Although missions are vital, little known about those mechanism controlling airway regeneration he...

Background & Aims: Leukoplakia is the most common premalignant or potentially malignant lesion of the oral mucosa and its potentiality for malignant transformation is unpredictable. The aim of the present study was to evaluate p53 expression in normal oral epithelium, leukoplakia and oral squamous cell carcinoma. Methods: The standard Biotin streptavaidin peroxidase immunohistochemical staining...

Introduction To evaluate the expression patterns of cytokeratin (K) 12, 13, and 19 in normal epithelium of the human ocular surface to determine whether K13 could be used as a marker for conjunctival epithelium. Methods: Total RNA was isolated from the human conjunctiva and central cornea. Those transcripts that had threefolds or higher expression levels in the conjunctiva than the cornea wer...

Pectins inhibit the growth of C. rodentium in vitro, preventing attachment rodentium to CMT93 epithelial cells. Through these antimicrobial effects, pectins protect epithelium from rodentium-induced barrier dysfunction and damage.

introduction: male infertility frequently occures after spinal cord injury (sci). however little in known about the acute effect of sci on male reproductive function. this study examined the spermatogenic changes during acute phase of sci. material and metods: in experimental groups sci was produced in male rats by t9 laminectomy and spinal cord transsection (n=23, age=70 days). control groups ...
