The diffraction of x-rays by the crystalline n-paraffins, C(36)H(74), C(44)H(90), and C(94)H(190), was examined at small angles – below seven degrees 2θ – as a function of temperature. The Bragg maxima (00l) that occur at these angles result fro

An adiabatic copper calorimeter was used to determine the heats of vulcanization of pale crepe natural rubber with sulfur for mixtures varying in composition from 0 to 32 per cent added sulfur. The side reaction that produces hydrogen sulfide was avo

The melting temperature of linear polyethylene has been obtained as a function of the time and temperature of crystallization. Recrystallization was minimized by a special melting procedure. By interpreting the melting points as characteristic of a g

The rate of isothermal bulk crystallization of poly(chlorotrifluoroethylene), Tm =221° C, was measured from 170° to 200° C. The intrinsic bulk crystallization, which accurately followed an n = 2 law, was shown to be a result of the injection of pr

In Guatemala, as in many places throughout the world, millions of indigenous people cook over non-ventilated indoor open fires. Indoor air pollution and accidental burns are well-known problems attributed to such fires. Efforts have been made to impr

Intrinsic abnormalities in transplanted eutopic endometrium are believed to contribute to the pathogenesis of pelvic endometriosis. Herein we investigated transcriptomic differences in human endometrial stromal fibroblasts (hESFs) from women with (hE

It is well established that cAMP signaling is an important regulator of the oocyte meiotic cell cycle. Conversely, the function of cGMP during oocyte maturation is less clear. Herein, we evaluated the expression of cGMP-hydrolyzing phosphodiesterases

The phosphodiesterase-11A (PDE11) family consists of four splice variants (PDE11A1-PDE11A4) that contain a conserved carboxyl-terminal (C-terminal) catalytic domain that hydrolyzes cAMP and cGMP; the amino-termini (N-termini) vary in length and amino

The physiological role of phosphodiesterase (PDE)11 is unknown and its biochemical characteristics are poorly understood. We have expressed human His-tagged PDE11A4 and purified the enzyme to apparent homogeneity. PDE11A4 displays K(m) values of 0.97
