Canine TSH may be measured at 30 minutes as part of a TRH stimulation test in the diagnosis of secondary hypothyroidism. Normal dogs should increase cTSH by at least 0.4 ng/mL. Total T3 (TT3) â The analysis of TT3 is of little value in the diagnosis of hypothyroidism principally because of the high prevalence of cross-reacting T3 autoantibodies (T3AA) in hypothyroid dogs.
The forward (leading) edge of the sail is called the luff, which, in a mainsail, is parallel to the mast. The aft (back) edge of a sail is called the leech (also spelled leach), which is opposite the luff, and forms the hypotenuse of the triangle.
A paddle is an implement for manually moving and guiding a small boat. A paddle consists of a shaft with a broad flat surface, called a blade, on one or both ends. The area where the blade joins or tapers into the shaft is called the throat. Paddles differ from oars in that they are used without oar locks, the attachments that clamp the oars to a boat.
