Influence of Perceived Helicopter Parenting, Critical Thinking Disposition, Cognitive Ability, and Learning Motivation on Learning Behavior among Nursing Students.

The purpose of this study was to determine the influence of perceived helicopter parenting, critical thinking disposition, cognitive ability, and learning motivation on learning behavior in nursing students in South Korea. The participants in this study were 149 sophomore nursing students from two universities using convenience sampling. The two universities were similar in terms of type, curricula, and size.

Multimodality Radionuclide Imaging in a Patient With Hereditary Paraganglioma-Pheochromocytoma Syndrome.

Hereditary paraganglioma (PGL)-pheochromocytoma (PCC) syndrome is a genetic disorder caused by a mutation of the tumor suppressor gene SDHD that results in a predisposition for head and neck PGLs and PCCs. We present a case of a 33-year-old woman where F-FDG PET/CT showed areas of increased uptake in both the adrenal and cervical regions, consistent with PCCs and PGLs, respectively. Further imaging revealed that PCCs were I-MIBG avid, whereas the PGLs were In-octreotide avid.

Excess phosphoinositide 3-kinase subunit synthesis and activity as a novel therapeutic target in fragile X syndrome.

Fragile X syndrome (FXS) is an inherited neurologic disease caused by loss of fragile X mental retardation protein (FMRP), which is hypothesized to mediate negative regulation of mRNA translation at synapses. A prominent feature of FXS animal models is exaggerated signaling through group 1 metabotropic glutamate receptors (gp1 mGluRs), and therapeutic strategies to treat FXS are targeted mainly at gp1 mGluRs. Recent studies, however, indicate that a variety of receptor-mediated signal transduction pathways are dysregulated in FXS, suggesting that FMRP acts on a common downstream signaling molecule.
