13. Pituitary metastasis of lung neuroendocrine carcinoma: case report and literature review
SUMMARY Metastasis to the pituitary gland is an unusual situation in clinical practice, but the frequency thereof is increasing due to the increased survival of cancer patients, and greater availability of imaging. In most cases, they are found between the sixth and seventh decades of life, as determined in image examination of patients with known malignant

14. Industry withdrawal from psychiatric medication development
Between 1950 and 1969, on a serendipitous basis, psychiatric drug development flourished. However, there has been a steep decline in the development of new medication classes. Instead of new molecular entities, slight molecular modifications producing “me-too” drugs attempted to garner market share. With failing profitability, industry is now withdrawing

15. Estudo da ativação de áreas hipotalâmicas e do tronco encefálico após o exercício físico agudo em ratos. / Pontomeduallry and hypothalamic areas activated after exercise in rats.
Durante o exercício físico existe uma intensa mobilização encefálica promovendo a tensão muscular, alterações circulatórias e respiratórias. A hipótese é que áreas encefálicas envolvidas no controle cardiorrespiratório participam no exercício físico agudo. Foram utilizados ratos Wistar divididos em grupo exercício e grupo repouso. Houve red

16. Effect of the ketamine/xylazine anesthetic on the auditory brainstem response of adult gerbils
The auditory brainstem response (ABR) is a test widely used to assess the integrity of the brain stem. Although it is considered to be an auditory-evoked potential that is influenced by the physical characteristics of the stimulus, such as rate, polarity and type of stimulus, it may also be influenced by the change in several parameters. The use of anestheti

17. Correlação clínico-laboratorial e de imagem do lúpus eritematoso sistêmico e da esclerose múltipla no HC/FM/UFG em Goiânia/Goiás de 2009 a 2010: ênfase nas manifestações neurológicas / Correlation of clinical-laboratorial and image of lupus erythematosus and multiple sclerosis in HC/FM/UFG at Goiânia/Goiás, 2009 to 2010: emphasis on neurological manifestations
Systemic Lupus Erythematosus - LES is an autoimmune disease involving multiple systems. In the Central nervous system-SNC is one of his more severe manifestations. One of the frames of Lupus neuropsychiatric - LES-NP, is a Demyelinating Syndrome - SD. SD in rare cases, may be the first manifestation of LES, resembling multiple sclerosis - MS in their symptom

19. O uso de células-tronco adultas em modelos experimentais de crises convulsivas. / The use of adult stem cells in experimental models of seizures.
In Brazil, it is estimated that epilepsy affects from 2% of the population, about three million people at different ages and social classes. The use of antiepileptic drugs is the most common form of seizure control, although about 50- 70% of patients with epilepsy are refractory to medication. Because of difficulties in finding effective treatments, it is cr

20. Expression of DLK1 and MEG3 genes in porcine tissues during postnatal development
The Drosophila-like homolog 1 (DLK1), a transmembrane signal protein similar to other members of the Notch/Delta/Serrate family, regulates the differentiation process in many types of mammalian cells. Callipyge sheep and DLK1 knockout mice are excellent examples of a fundamental role of the gene encoding DLK1 in muscle growth and fat deposition. DLK1 is loca

21. POLIOENCEFALOMALACIA EM RUMINANTES / POLIOENCEPHALOMALACIA IN RUMINANTS
In the first portion of this thesis, epidemiology, clinical signs and distribution of lesions in the brain of thirty one cases of polioencephalomalacia (PEM) in cattle from the Southern (13 cases) and Midwestern (18 cases) Brazil were studied. Morbidity (0.04%-6.66 %), mortality (0.04%-6.66 %), and lethality (50%-100%) rates were similar in both regions stud

22. O complexo nuclear vestibular do sagui (callithrix jacchus): caracterização citoarquitetônica e neuroquímica
Para os vertebrados, manter o equilíbrio corporal contra o campo gravitacional e ser capaz de orientar-se no ambiente são aspectos fundamentais para a sobrevivência, nos quais é essencial a participação do sistema vestibular. Como parte deste sistema, o complexo nuclear vestibular é a primeira estação central que, ao integrar várias informações (

23. Stem cell factor protects against neuronal apoptosis by activating AKT/ERK in diabetic mice
Neuronal apoptosis occurs in the diabetic brain due to insulin deficiency or insulin resistance, both of which reduce the expression of stem cell factor (SCF). We investigated the possible involvement of the activation of the MAPK/ERK and/or AKT pathways in neuroprotection by SCF in diabetes. Male C57/B6 mice (20-25 g) were randomly divided into four groups

24. Congenital hidranencephaly and cerebellar hypoplasia in water buffaloes / Hidranencefalia e hipoplasia cerebelar congênita em búfalos Murrah
Hereditary hydrancephaly and cerebellar hypolasia are reported in Murrah buffalos. Six calves, one female and 5 male out of 128 born between 2004 and 2008 in a farm in southern Brazil were affected. All affected calves were offspring from the same bull. No affected buffaloes were observed in the descendants of other three bulls used in the farm. Main clinica
