Calcium cobaltite (CCO) thermoelectric ceramics in Ca3Co4O9 and Ca2.95Ba0.05Co4O9 compositions were produced by a simplified chemical route developed this study. Undoped sintered at 1193 K for 12 h presented bulk density equivalent to 77% of the theoretical density, one highest values ever found conventionally undoped calcium cobaltite. The presence barium improved densification, reaching 80% d...

The bone mineral density increments in patients with sporadic primary hyperparathyroidism after parathyroidectomy have been studied by several investigators, but few have investigated this topic in primary hyperparathyroidism associated with multiple endocrine neoplasia type 1. Further, as far as we know, only two studies have consistently evaluated bone mineral density values after parathyroid...

The influence of the growth hormone/insulin-like growth factor-1 (GH/IGF-1) axis on the expression of low voltage-activated (LVA) calcium current in atrial tissue was investigated using spontaneous dwarf (SpDwf) rats, a mutant strain that lacks GH. Atrial myocytes from SpDwf rats express LVA and HVA calcium currents and the calcium channel alpha-1 subunit genes, CaV1.2, CaV2.3, CaV3.1, and CaV3...
