REIS, DONALD J., AND MICHEL C&NOD. Central neural reguhlion of carotid baroreceptor reflexes in the cat. Am. J. Physiol. sag(6) : m67-1279. 1965. -Reflex changes of the mean aortic blood pressure (BP) to carotid sinus stretch or carotid occlusion in anesthetized vagotomized cats were observed following ablation or electrical stimulation of brain. Decerebration produced augmentation of the depre...

Beginning with the work of Longet (1847) there has accumulated an impressive mass of evidence which indicates that the indispensable mechanism for the neural control of respiration is localized in the reticular formation of the caudal half of the medulla (Brown-Sequard, 1860; Gad and Marinesco, 1893; Bechterew, 1885; Kohnstamm, 1900; etc.). Although there have appeared sporadic assertions that ...

Aspergillus fumigatus is a life-threatening and increasingly frequent pathogen of the immunocompromised. Like other filamentous fungi A. fumigatus grows in a highly polar manner, adding new cell wall to the apical region of hyphae. mAbs were raised against isolated A. fumigatus cell walls. Fifteen antibodies bound reproducibly to isolated cell walls in ELISAs and to the walls of intact cells in...

Six inbred lines of Zea mays expressing different soluble (cytosolic) malate dehydrogenase (sMDH) zymogram phenotypes were analyzed genetically. sMDH was found to be coded for by unlinked duplicated loci in four of these inbred lines. The remaining two lines were found not to possess these duplicated loci. Furthermore, the duplicated loci, sMdh1 and sMdh2, have been found to be located on diffe...

Neuronal activity influences protein synthesis and neuronal growth. Availability of nutrients, especially leucine and arginine, regulates the mammalian target of rapamycin (mTOR) pathway that controls cell growth. We show that NMDA receptor activation markedly reduces arginine transport by decreasing surface expression of the cationic amino acid transporters (CAT) 1 and 3. Depletion of CAT1 and...
