Existence of a common precursor to ACTH and endorphin in the anterior and intermediate lobes of the rat pituaitary

“…Radioimmunoassays for ACTH using antiserum Bertha (with specificity for ACTH (1 1-24)) and antiserum Freddie (with specificity for ACTH (25)(26)(27)(28)(29)(30)(31)(32)(33)(34)(35)(36)(37)(38)(39)) were performed as described [8,20]. Synthetic hACTH(1-39) (from Drs W. Rittel and P.A.…”

“…The profile of immunoactive ACTH present in tissue extracts varies greatly depending on the specificity of the antiserum used. The binding of ''' I-labeled ACTH(1-39) to antiserum Freddie can be fully competed by ACTH(1-39), ACTH(2.5-39), and ACTH (34)(35)(36)(37)(38)(39) [there is no competition by ACTH(l-24)] ; this antiserum will be referred to as an extreme COOH-terminal ACTH antiserum. In anterior pituitary extracts (Fig 2A), the extreme COOH-terminal ACTH antiserum and the ACTH( 1 1-24) antiserum (Bertha) detect approximately the same amount of the two smaller forms of ACTH.…”

Structural Characterization of Sputtered Composite Stabilized ZrO₂ Thin Films

“…ZrO 2 coatings properties are a function of their structure and composition. Zirconia has three stable crystal structures as a function of temperature for atmospheric pressure conditions, a monoclinic phase (m-ZrO 2 ) stable up to 1170 ºC, a tetragonal phase (t-ZrO 2 ) stable between 1170 ºC and 2370 ºC and a cubic phase (c-ZrO 2 ) stable from 2370 to the melting point at 2680 ºC [5,6]. The transformation from a tetragonal to monoclinic structure upon cooling is undesirable for a high temperature protective coating due to an expansion of around 3-4% produced by the increased cell volume, which causes the subsequent failure of the coating by cracking.…”
