Although the majority of subjects were referred to our centre from other hospitals, PET/CT examinations and extraction procedures were all performed at a single centre.
Two biopsy specimens were obtained from the distal esophagus at 1 cm above the gastroesophageal junction under endoscopic examination in 18 patients (6 each with normal esophagus, reflux esophagitis, and Barrett's esophagus) and used for histological examination and DNA extraction.
Blood samples were taken from each study participant in the clinical examination and stored at +4°C until DNA extraction using a DNA extraction kit (PUREGENE ®DNA Purification Kit; Gentra Systems, Plymouth, MN, USA).
Outcomes are assessed using self-report questionnaires, joint examinations, analysis of x-rays, pressure algometry and extraction of data from hospital records.
The labor wards have equipment related to vacuum extraction, stitching, vaginal examination and delivery trays.
Affected status was determined by a history of cataract extraction or ophthalmologic examination, and the affected individuals all presented with bilateral congenital nuclear cataracts, which consisted of a central nuclear opacity affecting the embryonic and fetal nucleus of the lens, while the cortex remained transparent.
Primary tumours were fixed in 4% paraformaldehyde and embedded in paraffin for histological examination and cryopreserved for RNA and protein extraction.
With regularly scheduled oral examination and teeth scaling, which increased during our study period, other procedures such as root canal and extraction generally decrease.
Physical examination, serum extraction, complete blood cell count, electrolyte, sputum bacilloscopy, chest X-ray, and HIV test were carried out in the same institution.
Distraction and extraction.
