Greater production demands for ruminants require increased dietary inclusion of high-energy feeds. Grains and oil seeds are most commonly used to enhance diet energy density. However, use of such feeds proportionally increases the amount of dietary phytate phosphorus (P), which the ruminant may not be able to fully utilise. Our objectives for this study were to determine the extent of phytate d...

BACKGROUND AND OBJECTIVES Sentinel lymph node (SLN) mapping is an additional method for improving colorectal cancer nodal staging. The purpose of the study was to define the method's accuracy in nodal staging, its upstaging benefits and to identify the predictive factors for its failure. METHODS Lymphatic mapping was performed using technetium-99m-phytate and patent blue in 52 consecutive col...

Patients with gastroesophageal reflux disease may have disturbances of gastric motility, which could play a role in the pathophysiology of the disease. Recent studies have suggested that the gastric region just below the gastroesophageal junction may have a distinct physiological behavior. We determined whether patients with gastroesophageal reflux disease have abnormal residence of food in the...

In children the demand for calcium is particularly great and since their diet may contain considerable amounts of phytate, which is known to impair calcium absorption in adults (McCance & Widdowson, 1942) and in infants (Hoff-Jorgensen, Andersen, Begtrup & Nielsen, 1946), we have investigated the effect of a diet rich in phytate on the absorption of calcium and phosphorus in two children aged 1...

Phytic acid is a bioactive compound widely distributed in plant foods. Due to its molecular structure, phytic acid has affinity to polyvalent cations, such as minerals and trace elements, and could in this way interfere with their intestinal absorption in man and animals. Most studies in humans have therefore concentrated on the effect of phytate on mineral absorption and deficiencies. Currentl...

Objectives. Studies comparing outcome of single-(99m)Tc-methoxyisobutylisonitrile ((99m)Tc-sestamibi) and dual-tracer (99m)Tc-sestamibi scintigraphy in combination with (123)I before primary surgery of primary hyperparathyroidism (PHPT) are scarce. Methods. We compared (99m)Tc-sestamibi/(123)I and (99m)Tc-sestamibi in a single-centre retrospective series of 269 PHPT patients. The results were r...

Plant materials naturally contain minerals of iron, zinc and calcium [1]. However, plants also contain a compound called phytic acid, which can chelate the minerals and form insoluble complexes. Minerals from plant foods are unavailable for intestinal uptake when they are bound in phytate complexes [24]. Cereal-based diets low in meat, can thereby lead to micronutrient deficiencies of e.g. iron...

In this study, iron absorption from a tempe fermented whole-grain barley meal was measured, and results were compared to in vitro estimation of available iron from an equivalent meal. The tempe meal (TM) was prepared from barley fermented with Rhizopus oligosporus to reduce the phytate content <0.5 mol/g. Boiled barley with preserved phytate content was used as reference meal (BBM). Iron was ad...

Concentrations of Cu, Fe, Zn, Ca, and phytate were measured in dry-milled corn bran, wheat brans, and soybean hulls prior to being baked in bread and after passage through the human GI tract. Significant changes in mineral concentrations in the retrieved remnants compared to the starting materials were as follows: Cu, Fe, and Zn increased by factors of from two to four and Ca increased at least...

Sporadic supply interruptions of select radiopharmaceuticals on the global market require consideration of alternative agents to support continuity of essential nuclear medicine examinations. During an acute shortage of Xenon-133 and technetium-99 metastable (Tc-99m) diethylene-triamine-pentaacetate (DTPA), our institution used aerosolized Tc-99m hydroxymethylene diphosphonate (HDP), a radiopha...
