OBJECTIVES Abnormalities in neurotrophic systems have been reported in Alzheimer's disease (AD), as shown by decreased serum brain-derived neurotrophic factor (BDNF) levels and association with BDNF genetic polymorphisms. In this study, we investigate whether these findings can be detected in patients with mild cognitive impairment (MCI), which is(More)
There is a growing body of evidence implicating the neurotrophin brain-derived neurotrophic factor (BDNF) in the pathogenesis of schizophrenia. As circulating BDNF levels may reflect the BDNF levels in the brain, we assessed serum BDNF in 40 institutionalized schizophrenic patients and 20 healthy controls. Serum BNDF levels were significantly increased in(More)
Recent evidence suggests that peripheral markers related to oxidative stress, inflammation and neurotrophins may be altered during mood episodes in bipolar disorder. These can be seen as proxies of peripheral toxicity or markers of illness activity. Here we report an en bloc assessment of a set of previously described biomarkers in different mood states (n(More)
BACKGROUND Early life stress has been suggested to mediate vulnerability to affective disorders. Animal models of repeated maternal separation have shown reduced brain-derived neurotrophic factor (BDNF) levels in specific brain regions implicated with hypothalamic-pituitary-adrenal axis and memory formation. In addition, BDNF levels are also reduced in(More)
Gingival overgrowth (GO) is a side effect associated with some distinct classes of drugs, such as anticonvulsants, immunosuppressant, and calcium channel blockers. GO is characterized by the accumulation of extracellular matrix in gingival connective tissues, particularly collagenous components, with varying degrees of inflammation. One of the main drugs(More)
BACKGROUND Inflammatory and immune alterations occur and may be relevant in patients with schizophrenia. Chemokines are a subgroup of cytokines that play a major role in the recruitment of determined subsets of leukocytes into tissues. To date no study has evaluated whether levels of chemokines are altered in patients with schizophrenia. OBJECTIVE To(More)
Biomarkers are important factors in the identification of the frail elderly (higher risk of developing disease) and in assessing the impact of PTI. On the other hand, BDNF has been related to neuroprotection in a series of central nervous system diseases in older age. The levels of BDNF in groups of elderly women classified according to Fried phenotype(More)
Cryptococcus gattii is an emergent human pathogen. Fluconazole is commonly used for treatment of cryptococcosis, but the emergence of less susceptible strains to this azole is a global problem and also the data regarding fluconazole-resistant cryptococcosis are scarce. We evaluate the influence of fluconazole on murine cryptococcosis and whether this azole(More)
