Transport and storage of fresh and frozen gastric biopsy specimens for optimal recovery of Helicobacter pylori.
The viability of Helicobacter pylori in vitro and in gastric biopsy specimens was determined. Recovery rates were 94, 87, and 77% from biopsy specimens in Portagerm pylori in cooled containers after 1, 2, and 3 days of transport, respectively (n = 307), and 97% if stored and shipped in glycerol broth at -70 degrees C (n = 232).
متن کاملFrozen section of skin specimens.
CONTEXT Skin cancers are the most common malignancies in this country. Treatment of these tumors often involves assessment of margins, which may be performed by frozen section. OBJECTIVE This article discusses indications for frozen section, various approaches to gross examination of specimens, Mohs micrographic surgery, diagnostic pitfalls, methods to improve diagnostic accuracy, and special...
متن کاملWithin-person variability in urinary bisphenol A concentrations: measurements from specimens after long-term frozen storage.
BACKGROUND Bisphenol A (BPA) is an estrogenic contaminant of food and water associated with adverse developmental effects in laboratory animals. BPA has recently been linked to morbidity in adult humans, but studies of developmental effects in humans are methodologically more difficult. The ability to measure BPA in urine samples after long-term storage could aid in such studies. Because the ha...

متن کاملElectron microscopy of frozen hydrated biological specimens.
The use of frozen hydrated specimens for molecular structure determination is limited primarily by radiation damage. The radiation damage effect in frozen hydrated catalase crystals has been measured in terms of the loss of electron diffraction. The results show an improvement for this type or:specimen relative to wet hydrated or to glucose embedded catalase crystals at room temperature. Bright...
