This paper investigates the 3D microscopic structure of exvivo human cardiac muscle. Usual 3D imaging techniques such as DMRI or CT do not achieve the required resolution to visualise cardio-myocytes, therefore we employ X-ray phase contrast micro-CT, developed at the European Synchrotron Radiation Facility (ESRF). Nine tissue samples from the left ventricle and septum were prepared and imaged ...

In order to assess the extrapulmonary effects of multiwall carbon nanotubes (MWCNT), deposition of MWCNT and histopathologic changes in lung-associated lymph nodes (LALN) were examined in MWCNT-administered rats. At the age of 13 wk, male F344 rats were intratracheally instilled with MWCNT at a dose of 0 (vehicle), 40 or 160 μg/rat. The rats were sacrificed on Day 1, 7, 28 or 91 after instillat...

Herbal drug technology includes all the necessary steps for the conversion of botanical materials into medicines, where standardization and quality control are essential analytical tools to assure the correct identification of drugs. Advances in microscope technology and improvements in light and scanning electron microscopes have increased the accuracy and capabilities of microscopy as a mean ...

The cell membrane functions as a semi-permeable barrier, allowing a very few molecules across it while fencing the majority of organically produced chemicals inside the cell. Electron microscopic examinations of cell membranes have led to the development of the lipid bilayer model (also referred to as the fluid-mosaic model). The most common molecule in the model is the phospholipid, which has ...

BACKGROUND The development of asymptomatic gross or microscopic hematuria is relatively common in children. OBJECTIVE To evaluate the clinical importance of hematuria in children and the necessity for such an evaluation using a defined diagnostic protocol. DESIGN The protocol included a personal and family history, physical examination and blood pressure determination, and a set of comprehe...

The aim of this study was to prospectively evaluate endoscopic ultrasonography and microscopic examination of duodenal bile in the diagnosis of cholecystolithiasis not detected by conventional ultrasonography. Forty five consecutive patients (26 females, 19 males, mean age: 50 years) with suspected cholecystolithiasis and at least two normal transcutaneous ultrasonography examinations were incl...

OBJECTIVE The aim of this study was to investigate several macroscopic and microscopic features of placenta in cases with impaired gestational glucose tolerance. METHODS Seventy-five gm World Health Organization criteria for the diagnosis of gestational diabetes and impaired gestational glucose tolerance were followed during the period June 1999 through to June 2000, at the Maternity Hospital...

Nosema ceranae as a fungal parasite has been reported from the Apis mellifera in all continents. It causes reduced longevity, depopulation, decreased production, and colony losses honeybee colonies. This study aimed to determine prevalence of N.ceranae apiaries Mazandaran province. In this study, we randomly selected 320 hives thirty-two collected twenty old honeybees apiaries. The samples were...

BACKGROUND AND OBJECTIVES In Iran, anaplasmosis is normally diagnosed with traditional Giemsa staining method. This is not applicable for identification of the carrier animals. The aim of this study was to compare the detection of Anaplasma marginale in two different numbers of microscopic fields (50 and 100) using conventional Giemsa staining method compared with the PCR-RFLP technique. MATE...
