| | Antioxidant-oxidant balance in the glomerulus and proximal tubule of the rat kidney -- Gwinner et al. 509 (2): 599 -- ... |
 | | A comprehensive view of the physiological antioxidant- oxidant balance in the glomerulus and proximal tubule would aid in the understanding of oxygen radical-induced injury in glomerular and tubulo-interstitial disease. | | | Results from experiments using chemiluminescence in vital tissues suggest that changes in the antioxidant-oxidant balance have an effect on oxygen radical levels. | | | Compared with the young rats, tubules of 8-month-old rats had significantly higher superoxide anion rates and lower superoxide dismutase activity, whereas NADH- and NADPH-dependent oxidase activities were unchanged. |

| | By expressing G-CaMP in all neurons, we identified the V glomerulus as the only region in the antennal lobe that shows response to CO, which elicits innate avoidance behavior in the T-maze paradigm. | | | By emplying the FLP-out technique to generate flies containing only one labeled PN, we are able to relate the axonal arbor with the glomerulus a given PN innervates. | | | We have begun to map olfactory activity in the fly brain with this imaging technique. |

| | Renal Physiology |
| | (1) The Glomerular hydrostatic pressure is the blood pressure within the glomerulus. | | | There is a 20 mm Hg pressure gradient, between the pressure in the glomerulus and Bowman's capsule, which causes fluid to flow out of the blood (in the glomerulus) and into Bowman's capsule. | | | 2) efferent arterioles are smaller than afferent arterioles; thus, there is an increase in blood pressure within the glomerulus. |

| | THE FILTRATION AND REABSORPTION PAGE |
| | The glomerulus is a high pressure capillary network and is the renal structure responsible for filtration of plasma. | | | Filtration is controlled to some extent by the diameter of the afferent and efferent arterioles; there is very little resistance across the capillary bed in the glomerulus, such that very little hydrostatic pressure is lost between the afferent (60 mmHg) and efferent (55 mmHg) arterioles. | | | The central filtration device is the "glomerulus." While the glomerulus is the central part of the filtration apparatus, it is really not the only part. |

| | PNs that branched in the same glomerulus and were activated by the same pheromone component also showed the strongest coincident responses to each odor pulse. | | | Thus, when two adjacent glomeruli receive their inputs simultaneously, the temporal tuning of output from each glomerulus is enhanced by reciprocal and inhibitory interglomerular interactions. | | | Using the sphinx moth, an insect that meets these specific criteria, we recorded odor-evoked responses simultaneously from pairs of projection neurons (PNs) innervating the same or different glomeruli in the macroglomerular complex (MGC), which is involved in processing pheromonal information. |
