The aim of this paper is to present several popular methods for in vitro culture of osteocytes and osteocyte cell lines. Osteocytes are located extremely suitably within the calcified bone matrix to sense mechanical signals, and are equipped with a multitude of molecular features that allow mechanosensing. However, osteocytes are more than specialized mechanosensing cells. Several signaling mol...
Background and Aim: Tuberculosis is an infectious disease with worldwide distribution. Based on WHO report one third of people are affected with mycobacterium tuberculosis. Today, the traditional bacteriological methods are only available using diagnostic methods for detection of tuberculosis. Innovation of a simple and efficient method for the diagnosis of tuberculosis is one of the most impor...
No association was found between inflammatory bowel disease and infection with C. trachomatis or C. psittaci when patients were tested for the presence of these organisms using immunohistological, cell culture isolation, and serological techniques.
A human osteogenic sarcoma cell culture is useful in the immunofluorescence serological test for detecting human cytomegalovirus antibody. These sarcoma cells are chronically infected with human cytomegalovirus and provide a constant number of immunofluorescence-positive cells.
BACKGROUND. Blood culture-negative endocarditis (BCNE) may account for up to 31% of all cases of endocarditis. METHODS. We used a prospective, multimodal strategy incorporating serological, molecular, and histopathological assays to investigate specimens from 819 patients suspected of having BCNE. RESULTS. Diagnosis of endocarditis was first ruled out for 60 patients. Among 759 patients with BC...
Serological tests for tuberculosis are inaccurate and WHO has recommended against their use. Although not used by the Revised National TB Control Programme (RNTCP), serodiagnostics are widely used in the private sector in India. A root-cause analysis was undertaken to determine why serological tests are so popular, and seven root causes were identified that can be grouped into three categories:...
there is less published research about how teachers in efl contexts respond to students who are relatively less mature and less competent l2 writers. while writing researchers have examined various issues concerning peer and teacher response in writing-oriented classes, little research has centered on the effect of collaborative tasks particularly dictogloss on writing skills. output collaborat...
Background and Aims: The aim was to determine the role of dominant serovars of Listeria monocytogenes (L. monocytogenes) in spontaneous abortions, using isolation methods and polymerase change reaction (PCR). Materials and Methods: A total of 258 samples comprising of placental tissue, vaginal swabs and blood were collected from 123 patients with spontaneous abortion. L. monocytogenes was iden...
An accelerated, direct immunofluorescent-antibody procedure was developed for the detection of Salmonella in food products. This method includes pre-enrichment and selective enrichment but eliminates many of the washing and smear treatments present in existing methods. Commercially available fluorescein-conjugated somatic antiserum was used in comparing this method with conventional culture, bi...
Background: Cervical cancer is the second leading cause of cancer death among women. In this cancer, the effects of prevention, early diagnosis and treatment more than other cancers decrease the mortality rate. In 1970 human papilloma virus (HPV) was introduction as major etiologic factor of cervical cancer. Different studies throughout the world revealed strong correlation between HPV and canc...
