Bacterial colonization of Hydra hatchlings follows a robust temporal pattern

A Survey about the Temporal Pattern of Stroke Occurrence

Background: Temporal variation of stroke onset is suggested in some studies contained somewhat varieties. It is proposed that some predisposing changes occur in some ascertained times consequently resulted in stroke occurrence in some special times. Objective: To determine the circadian and circaseptan variation of stroke onset. Materials and Methods: This cross sectional study was conducted ...

Bacterial Colonization in Tracheal Tubes of ICU Patients

  Background and Objectives: Nosocomial infections are one of the most important worldwide health and increased patients hospital stay, therapeutic problem and mortality rate. This study was designed to determine the frequency of microorganisms isolated from tracheal tube in patients admitted to ICU Shaheed Mostafa Khomeini Hospital Tehran, Iran, from 2001-2005. Patients and Methods: In this ...

The Oropharyngeal Bacterial Colonization of Patients with Endotracheal Tube

Abstract Background and Objective: Bacterial colonization in upper respiratory airways is one of the major risk factors for the development of the ventilator–associated pneumonia (VAP), which is the most common and serious hospital-acquired infection in intensive care unit (ICU). The aim of this study was to determine the frequency of oropharyngeal microorganisms of patients with tracheal t...

Coloration and pattern of hatchlings of six Pelomedusa species

Pattern of epithelial cell cycling in hydra.

We have investigated the spatial pattern of epithelial cell cycling in a mutant strain of Hydra magnipapillata (sf-1). This strain has temperature sensitive interstitial stem cells and thus polyps containing only epithelial cells can be obtained by growth at the restrictive temperature. Epithelial animals were pulse labeled with the thymidine analog 5'-bromo-2'-deoxyuridine (Brdu) and stained w...
