The Viewpoint by Ran Arieli published below addresses the topic of the physiology of “mixed-gas diving.” You are invited to submit a brief commentary on this Viewpoint, which will be reviewed by Journal editors for possible publication in the Journal of Applied Physiology. Please limit your comment to 250 words and 5 peer-reviewed published references. NON-AIR OR MIXED-GAS DIVING was developed ...

Protein concentrates and by-products produced from ground wheat were analyzed for amino acid composition, protein, starch, fat, fiber, ash, and various neutral carbohydrates. The concentrates contained from 83 to 92% protein (nitrogen X 5.7), 2.1 to 2.6 g of lysine, 2.5 to 3.5 g of total sulfur amino acids per 16 g of nitrogen, 1.5 to 7.4% fat, 0.9% ash, and from 1.8 to 3.9% total carbohydrate....

Understanding toothed whale (odontocete) diving gas dynamics is important given the recent atypical mass strandings of odontocetes (particularly beaked whales) associated with mid-frequency naval sonar. Some stranded whales have exhibited gas emboli (pathologies resembling decompression sickness) in their specialized intramandibular and extramandibular fat bodies used for echolocation and heari...

Purified preparations of diphtheria antitoxin have been obtained by digestion of the toxin-antitoxin complex with trypsin, followed by fractional precipitation with ammonium sulfate. The various fractions obtained in this way are all 90 per cent or more precipitated by diphtheria toxin but combine with different quantities of the toxin. The fraction precipitated between 0.33 and 0.5 saturated a...

the solubility of k2so4 in water at 25°c was determined. comparing the value ofthermodynamic solubility product constant, ksp(th), (ksp(th) = exp (-δgodiss rt) of the mentionedsalt to the value of concentration solubility product, ksp(c) which is obtained from the observedsolubility, s/mol-1, ksp(c) = 4s3, revealed a great difference. the difference can be satisfactorilyexplained using debye- h...

abstract: different techniques have been employed to improve the technological properties of meat. one of the most important techniques is adding proteolytic enzymes which could simultaneously increase the tenderization and solubility of meat proteins. the purpose of this investigation was to study the effect of different levels of the enzyme ficin on ovine and bovine meat and to determine the ...

Sodium metabisulfite (Na2S20S) was used to inactivate trypsin inhibitors in whole and cracked soybeans. Soybeans (400 g) steeped with 1600 ml aqueous O.IM Na2S20S at 30°C and 65°C for 2and 3-h were dehulled, dried, flaked and then defatted with either 6 batch extractions of hexane at ambient temperature or with supercritical CO2 for 15 min at 12,000 PSI and 84°C. The 2-h steep treatment at 65°C...
