All puffed out: do pufferfish hold their breath while inflated?
The inflation response of pufferfishes is one of the most iconic predator defence strategies in nature. Current dogma suggests that pufferfish inflation represents a breath-holding response, whereby gill oxygen uptake ceases for the duration of inflation and cutaneous respiration increases to compensate. Here, we show that the black-saddled pufferfish (Canthigaster valentini) has an excellent c...
متن کاملChallenges of maintaining breath-hold conformity for breast patients while using the deep inspiration breath-hold technique
Deep inspiration breath-hold (DIBH) is used for whole breast radiotherapy, as a means of providing better dose homogeneity. This can be achieved by lower doses to the organs at risk, less patient movement and better set up. Most patients offered DIBH treatment are left-sided breast cancer, or ductal carcinoma in situ (DCIS) patients, due to the proximity of the heart to the chest wall so it is ...
متن کاملHold your breath!
R egeneration, the process by which an animal restores lost cells or body parts, occurs throughout the animal kingdom, including vertebrates, planarians and cnidarians such as hydra (Tanaka & Reddien, 2011). However, the ability to regenerate varies between species, and within a species it can be different for different body parts. Salamanders, such as axolotls and newts, possess the most impre...
متن کاملCellular Glucose Uptake During Breath-Hold Diving in Experienced Male Breath-Hold Divers
BACKGROUND The physiological and pathophysiological mechanisms that govern diving, both self-contained underwater breathing apparatus (SCUBA) and breath-hold diving (BH-diving), are in large part well known, even if there are still many unknown aspects, in particular about cell metabolism during BH-diving. The scope of this study was to investigate changes in glycemia, insulinemia, and the cate...
متن کاملAdverse events in competitive breath-hold diving.
Medical observations are reported from an eight-day world championship breath-hold diving competition involving 57 participants. The deepest dive was to 75 metres, and the longest breath-hold time exceeded 9 minutes. There were 35 diving-related adverse events witnessed or reported, including transient loss of motor control due to hypoxia, syncope during ascent, hemoptysis, and pulmonary edema....
