    Abstract: This book presents the latest knowledge on the roles of progranulin (PGRN) in normal physiology and pathology and explores the emerging significance of PGRN as a therapeutic target and biomarker in various CNS disorders, including frontotemporal lobe degeneration and other neurodegenerative diseases. Following initial recognition of the importance of PGRN in sexual differentiation of the developing brain and adult neurogenesis, it was subsequently discovered that PGRN acts as a chaperone of lysosomal enzymes and plays a crucial role in maintaining cellular protein homeostasis. It has also been found that sex steroids modulate the expression of PGRN and its trophic effects in the developing CNS and that PGRN directly or indirectly influences neural stem and progenitor cells. Against this background, deeper understanding of the molecular and functional properties of PGRN would provide fresh impetus for the development of mechanism-based therapeutic approaches for multiple disorders. Medications targeting the recovery of lysosomal function appear to hold particular promise in patients with neurodegenerative diseases resulting from PGRN insufficiency. In examining multiple aspects of this fascinating field, the book will be of high value for researchers and graduate students

    Notes: Summary A case of secretory meningioma with numerous meningothelial rosettes is reported. A 66-year-old man with moyamoya disease gradually developed skull deformity, and underwent surgery for the skull tumor overlying the hemisphere. Histological examination disclosed numerous meningothelial rosettes quite similar to those induced by subarachnoid injection of epinephrine and pseudopsammoma bodies described by Kepes. This may be the first case of meningioma associated with numerous rosette formations.

    Notes: Summary The origin of nerve fibers to the superficial temporal artery of the rat was studied by retrograde tracing with the fluorescent dye True Blue (TB). Application of TB to the rat superficial temporal artery labeled perikarya in the superior cervical ganglion, the otic ganglion, the sphenopalatine ganglion, the jugular-nodose ganglionic complex, and the trigeminal ganglion. The labeled perikarya were located in ipsilateral ganglia; a few neuronal somata were, in addition, seen in contralateral ganglia. Judging from the number of labeled nerve cell bodies the majority of fibers contributing to the perivascular innervation originate from the superior cervical, sphenopalatine and trigeminal ganglia. A moderate labeling was seen in the otic ganglion, whereas only few perikarya were labeled in the jugular-nodose ganglionic complex. Furthermore, TB-labeled perikarya were examined for the presence of neuropeptides. In the superior cervical ganglion, all TB-labeled nerve cell bodies contained neuropeptide Y. In the sphenopalatine and otic ganglia, the majority of the labeled perikarya were endowed with vasoactive intestinal polypeptide. In the trigeminal ganglion, the majority of the TB-labeled nerve cell bodies displayed calcitonin gene-related peptide, while a small population of the TB-labeled neuronal elements contained, in addition, substance P. In conclusion, these findings indicate that the majority of peptide-containing nerve fibers to the superficial temporal artery originate in ipsilateral cranial ganglia; a few fibers, however, may originate in contralateral ganglia.

    Notes: Abstract The authors describe the perivascular innervation of cerebral circulation. The different nerve fiber systems can be classified as follows: 1. Sympathetic (noradrenaline, neuropeptide Y), 2. Parasympathetic (acetylcholine, vasoactive intestinal peptide/peptide histidine isoleucine (methionine), 3. Sensory (tachykinins, calcitonin gene-related peptide). Each of these systems is outlined by their basic anatomical and physiological facts. Then, the etiology of cerebral vasospasm after subarachnoid hemorrhage is discussed in relation to the cerebrovascular innervation.
