(1) On Midway Island in the Hawaiian chain, a bolus , or mass of chewed food, coughed up by one bird included many identifiable objects.(2) The cardiac sphincter opens because of increasing pressure in the esophagus from the food bolus .(3) Peering then through the glass, which demarcated the realms wherein we exist, I felt the bolus of grief form in my gullet.(4) A low power laser warms the targeted tissue and releases a bolus of photosensitizer.(5) The goal is a reduction in the resting pressure to allow passage of the food bolus into the stomach.(6) Treatment was given intravenously as a bolus for the lowest two doses and as a 30-minute infusion for the two highest doses.(7) This may be due to a large bolus of concentrated solute reaching the myocardium.(8) Subsequently, the bolus is transferred to the digestive tract where it is chemically reduced.(9) Our analysis shows that the two weak stages in the system are drugs that require multiple step preparation and administration of doses as a bolus .(10) I said, nonchalantly gulping down a bolus of fear.(11) Unfortunately, the bacon lump was much larger than I expected, and as a half-chewed bolus disappeared down my throat, I realised I wouldn't be able to swallow it.(12) The tongue directs the bolus of chewed food to the pharynx as an initial step in the involuntary reflex swallowing mechanism.(13) Of the eight legs injected with a single 30-ml bolus of dye, seven developed high pressures and one did not.(14) During summer and autumn, jays routinely make hundreds of food caches per day, placing each saliva-coated bolus in a separate arboreal site.(15) Typically, local anesthetics and opiates, alone or in combination, are administered through the epidural catheter as an infusion or a bolus to provide analgesia.(16) The drug bolus was followed by continuous infusion of 50 g/kg/hour until the experiment ended at 48 hours.
