Effects of elastic anisotropy on strain distributions in decahedral gold nanoparticles.

Metallic nanoparticles exhibit exceptional optoelectronic properties with applications in plasmonics, biosensing and nanomedicine. Recently, new synthesis techniques have enabled precise control over the sizes and shapes of metal nanoparticles, occasionally leading to morphologies that cannot be properly characterized using standard techniques. An example is five-fold-twinned decahedral Au nanoparticles, which are intrinsically strained as a result of their unique geometry.

Comparison of the efficacy and tolerability of dexketoprofen and ketoprofen in the treatment of primary dysmenorrhea.

Dexketoprofen, the pure S(+)-enantiomer of ketoprofen, is a promising new analgesic, but few clinical trials have yet examined its efficacy and tolerability. In this study, patients with a history of primary dysmenorrhea were treated with dexketoprofen doses of 12.5 and 25 mg, ketoprofen 50 mg, and placebo using a randomized, four-way crossover design.

Evaluation of the fibrinolytic system in full-term neonates.

Plasminogen activity and antigen, euglobulin fibrinolytic activity, tissue-type plasminogen activator activity and antigen urokinase-type plasminogen activator antigen, plasminogen activator inhibitor-1 activity and antigen, plasminogen activator inhibitor-2 antigen, tissue-type plasminogen activator/plasminogen activator inhibitor complexes, alpha 2-antiplasmin, histidine-rich glycoprotein, and fibrinogen/fibrin degradation products were measured in blood samples taken from the umbilical vein of 100 healthy full-term newborns. Results were compared with a control group of 30 healthy adults. The overall fibrinolytic activity assessed on fibrin plates was significantly increased (P < 0.

[Birth weight in twins (author's transl)].

Birth weight of 1,134 twin pairs have been studied in the Maternity "La Paz" (Madrid) along years 1969-74. Mean weight among twin pairs of the like sex is 2,493.78 +/- 20.
