A new species of Solanum from the Australian "andromonoecious bush tomato clade" of Solanum subgenus Leptostemonum is described. Solanum jobsonii Martine, J.Cantley, & L.M.Lacey, sp. nov. is part of the S. eburneum Symon species group. It most closely resembles S. eburneum and S. watneyi Martine & Frawley of the northwestern part of the Northern Territory, but is separated geographically from t...

Cerebrospinal fluid-borne metastases were demonstrated by metrizamide myelography in 20 children with primary intracranial tumors, posterior fossa medulloblastomas being the most common. The lumbosacral region was affected most often, with nerve root thickening, nodularity, and irregularity of the thecal sac. Cord cloaking, nodularity, and meningeal disease were common in the cervical and thora...

Quasar source counts at millimeter and sub-millimeter wavelengths will be important for phase and delay calibration as well as focus and pointing observations. Some of these observations can be done at low frequencies, but some observations will need to be done at the target frequency. Having a good knowledge of the high frequency quasar source counts will help us with the ALMA calibration plan...

portant causes of dementia, which are second only to Alzheimer’s disease in the elderly. Based on clinical observations, patients with vascular dementia often show a series of mental disorders, such as personality alterations, memory deficits, and thinking variations. The main pathophysiologic changes in the disorders include neuronal damage, hippocampal sclerosis, abnormal glial cell activatio...
