\n\nMethods: We performed a retrospective analysis of 71 cases

with coccidioidomycosis involving the CNS seen from 1996 to 2007 at a referral medical center in southern Arizona.\n\nResults: The only presenting symptom found in the majority of patients was headache. Those who were immunocompromised (most commonly HIV/AIDS and chronic steroid therapy) were at increased risk, but diabetics were not at increased risk. There was a preponderance of males (2:1) and people of Hispanic, African, and Asian (especially Pacific Isles) background. CSF anticoccidioidal antibody and culture were frequently negative on presentation, but in these cases, the serum antibody test was usually positive. Imaging studies were helpful in two thirds of cases, most commonly demonstrating basilar meningitis or hydrocephalus, which frequently required ventriculoperitoneal shunting. Most were treated with fluconazole, ML323 and prognosis was good for most of those who remained on treatment.\n\nConclusions: Coccidioidal meningitis remains a diagnostic challenge, but the diagnosis can usually be made successfully when coccidioidal serum and CSF antibodies and cultures are combined with appropriate imaging studies.

“Under physiological

conditions, angiogenesis is regulated by the local balance between endogenous stimulators and inhibitors of this process. In pathological states such as chronic inflammation and tumor growth, there is an imbalance between endogenous stimulator and inhibitor levels, leading to an “angiogenic switch”. Various inhibitors of angiogenesis, including angiostatin, endostatin and thrombospondins,

are B-Raf mutation found in the body. It is uncertain why the body possesses so many inhibitors, and also how these inhibitors interact to overcome the effects of angiogenesis stimulators. This review summarizes the present knowledge about endogenous inhibitors of angiogenesis. (C) 2008 Elsevier Ltd. All rights reserved.”
“Fuelled by the generalized degradation of freshwater ecosystems, the development of tools to assess their ecological status has been the focus of intensive research in the last decades. Although fish are one of the key biological quality elements used to describe the ecological status of rivers, fish metrics that accurately respond to disturbances in Mediterranean trout type streams are still lacking. In these systems, multimetric indices are not optimal indicators because of their low species richness and abundances, thus alternative approaches are needed. Since carrying capacity defines the potential maximum abundance of fish that can be sustained by a river, its relationship with actual density (D/K ratio) could be an accurate indicator of population conservation status and consequently of the ecological status of the river.
