Both behavioral and neuroimaging evidence support a female advantage in the perception of human faces. Here we explored the possibility that this relationship may be partially mediated by female sex hormones by investigating the relationship between the brain's response to faces and the use of oral contraceptives, as well as the phase of the menstrual cycle. First, functional magnetic resonance...

BACKGROUND Therapy for advanced epithelial ovarian cancer (OC) includes first line platinum/taxane-containing chemotherapy and re-treatment with platinum-containing regimens for disease recurrence in patients likely to respond again. Single-agent, non-platinum, cytotoxic agents are commonly used to treat patients resistant to platinum retreatment, but these agents are associated with dose-limit...

In this paper, the structure of Al2O3 is modified with magnesium to synthesize MgAl2O4 as an oxygen carrier (OC) support. The surface properties and structural stability of the modified support are improved by the incorporation of magnesium in the structure of the support and additionally by narrowing the pore size distribution (about 2.3 nm). Then, iron oxide is impregnated on both an Al2O3 su...

Administration of oral contraceptive (OC) has been associated with body fluid retention and in high doses over a long period, promotes hypertension. This present investigation tests the hypothesis that the dietary calcium supplementation increases salt and water excretion in OC (norgestre/ethinylestradiol) treated 32 female albino rats randomly distributed into four (1-4) groups of 8 rats each:...

BACKGROUND Osteocalcin (OC) is produced by osteoblasts during bone formation, and circulating OC has been used in clinical investigations as a marker of bone metabolism. OC is excreted into urine by glomerular filtration and can be found in urine as midmolecule fragments. METHODS We developed and evaluated three immunoassays (U-MidOC, U-LongOC, and U-TotalOC) for the detection of various mole...

This study aimed to evaluate the efficiency of organic compost produced through composting in development Moringa oleifera seedlings. The experiment was carried out a greenhouse Feira de Santana- BA, Brazil. design randomized blocks (RBD), with seven treatments per block and four replicates. following were tested: commercial substrate; sand (S); S/organic (OC) 80/20; S/OC 60/40; 40/60; 20/80; 0...

Conceptual models suggest that stability of organic carbon (OC) in soil depends on the source of plant litter, occlusion within aggregates, incorporation in organomineral complexes, and location within the soil profile. Density fractionation is a useful tool to study the relevance of OC stabilization in aggregates and in association with minerals, but it has rarely been applied to full soil pro...

We determined the fluxes of total mercury (HgT), total organic carbon (TOC), and dissolved organic carbon (DOC) from five upland/ peatland watersheds at the watershed outlet. The difference between TOC and DOC was defined as particulate OC (POC). Concentrations of HgT showed moderate to strong relationships with POC (I?* = 0.77) when ah watersheds were grouped. Although POC only accounts for 10...

The recent enthusiastic reception of the MIT OpenCourseWare (OCW) project has significantly improved the general awareness of Open Courseware (OC). However, many other lesser known projects and resources can also be classified as OC. The OC movement can potentially provide a vast pool of resources to satisfy diverse needs of Computer Science (CS) educators. However, there are only limited discu...

BACKGROUND AND PURPOSE Literature suggests a small increased risk of ischemic stroke with oral contraception (OC) use. We evaluated the association of stroke and OC use in women on the basis of whether they recalled being advised by a physician not to use OC or to discontinue OC use because of the presence of stroke risk modifiers, and whether such advice resulted in behavioral change. METHOD...
