Glutamatergic transmission in the nucleus tractus solitarii: from server to peripherals in the cardiovascular information superhighway

Afferent nerves carrying signals from mechanoreceptors in the aortic arch and carotid sinus terminate predominantly in the nucleus tractus solitarii (NTS). Signal transduction and neurotransmission in the NTS are critical for central cardiovascular reflex control, but little was known about either until the late 1970's. None of the numerous neuroactive chemicals found in the NTS had met strict criteria as a neurotransmitter in the baroreflex arc until data suggested that the excitatory amino acid L-glutamate (GLU) might be released from baroreceptor afferent terminals in the NTS. In anesthetized animals microinjection into the NTS of GLU, which can be demonstrated in terminals in the NTS, produces cardiovascular responses like those seen with activation of the baroreceptor reflex. Similar responses occur in awake animals if the chemoreceptor reflex is eliminated; otherwise, in conscious animals responses mimic those of chemoreceptor reflex activation. GLU is released in the NTS upon selective activation of the baroreceptor, and possibly the chemoreceptor, reflex. Responses to selective agonists as well as baroreflex responses are eliminated by GLU antagonists microinjected into the NTS. Non-NMDA (N-methyl-D-aspartic acid) receptors seem to predominate at primary baroreceptor synapses in the NTS while NMDA receptors may be involved at later synapses. Although inhibition of soluble guanylate cyclase attenuates responses to ionotropic glutamate agonists in the NTS, nitric oxide does not seem to play a role in glutamate transmission in the NTS. GLU may also participate in transmission at cardiovascular neurons beyond the NTS. For example, a role has been suggested for GLU in the ventrolateral medulla and spinal cord. Work continues concerning GLU signal transduction and mechanisms that modulate that transduction both at the NTS and at other cardiovascular nuclei

Avaliação do teor de cobre e zinco em carnes cruas, processadas termicamente, resfriadas e congeladas no período de um mês

Para que elementos químicos, como o cobre e o zinco, sejam utilizados pelos sistemas biológicos, é necessário que estejam disponíveis para absorção, sendo assim, apenas a sua abundância na natureza não é fator que garanta a sua absorção. As carnes bovinas e de aves são de grande importância na alimentação, justamente por serem alimentos fonte de proteínas de alto valor biológico e lipídios. Processos de conservação através de refrigeração e congelamento, bem como processamento térmico, podem alterar fisicamente as carnes. Este trabalho tem como objetivo avaliar o comportamento de cobre e zinco em carnes resfriadas e conservadas em temperatura de congelamento por um período de 1 mês, processadas termicamente e in natura. Os teores de cobre e zinco foram determinados através da espectroscopia de absorção atômica. Os dados foram tratados estatisticamente através do teste de Grubs e t de Student. Mesmo com perdas no processamento térmico, e com a conservação em temperatura de congelamento durante o período de 4 semanas, o teor de cobre na maioria das amostras estudadas foi superior a 0,025mg%, e o do zinco superior a 0,3mg% para as amostras de carnes de aves e 0,6mg% para as amostras de carnes bovinas.

Brazilian roasted coffee oil obtained by mechanical expelling: compositional analysis by GC-MS

A preliminary analysis by GC-MS comparing the mass spectrum of the compounds with the Wiley 275 L mass spectral data base was used to identify the fatty acids and mainly, some volatile compounds responsible for the flavor of the roasted coffee oil. The oil was obtained by mechanical expelling of Brazilian beans (Coffea arabica) roasted at 238ºC for 10 minutes. Different sample preparation methodologies such as headspace, adsorbent suction trapping and esterification were used. It was possible to identify pyrazines, pyridines, furan derivatives and other compounds not reported in the literature.

Graduale (MS C.III.36, "Ilmajoen Graduale II")

A very small gradual and hymnary, for the most part copied in the last years of the sixteenth century or in the first quarter of the seventeenth. Assuming that Henricus Jacobi indeed signed his name in the sixteenth century (as Kurvinen reports), some of the manuscript was copied in that century: in lieu of a more accurate indicator the date of the manuscript appears to fall between 1589 and Mathias Benedicti's additions in 1635. The book was kept, perhaps even copied but certainly used, at Ilmajoki from the seventeenth century, and came from there to the University Library.

Antiphonarium (MS A.ö.II.29, Ilmajoen antifonarium)

Complete critical and codicological description of the book and its contents available in the Codices Fennici -database.

Psalterium Davidicum (MS C.IV.24)

Complete critical and codicological description of the book and its contents available in the Codices Fennici -database.

Graduale (MS A.ö.II.55, Ilmajoen graduale)

A graduale (defect) from Ilmajoki. Written in three parts, part I (fols. 1-134) dating probably from the 1540's, part II (fols. 135-140) probably from the 1550's and part III (fols. 141-194) from the 1530's.

Graduale (MS Coll. 762.3)

A Lutheran gradual copied apparently by one scribe at the end of the sixteenth century and probably repaired (fol. 29) in the beginning of the seventeenth century.

Graduale (MS C.ö.III.17)

A Lutheran gradual from Kalanti. As covers used a fragment of the Liturgical calendar of the Diocese of Turku, Saec. XIV 2/2, Diocese of Turku.

Legendarium (MS C.ö.I.1)

Much of the manuscript is taken up by a collection Sunday sermons and by a selection from Legenda Aurea. The manuscript features several scribes and may be a result of compiling text from different sources.

Summa Theologiae (MS Coll. 762.2)

An abridgement or selections from Thomas Aquinas, Summa theologiae. The text strongly modifies and abridges the original.

Sermones de tempore et de sanctis (MS C.ö.I.6)

Complete critical and codicological description of the book and its contents available in the Codices Fennici -database.

Missale (MS C.ö.IV.7, "Oripään missale I")
