Complexin 3 Increases the Fidelity of Signaling in a Retinal Circuit by Regulating Exocytosis at Ribbon Synapses
No full textSummaryComplexin (Cplx) proteins modulate the core SNARE complex to regulate exocytosis. To understand the contributions of Cplx to signaling in a well-characterized neural circuit, we investigated how Cplx3, a retina-specific paralog, shapes transmission at rod bipolar (RB)→AII amacrine cell synapses in the mouse retina. Knockout of Cplx3 strongly attenuated fast, phasic Ca2+-dependent transmission, dependent on local [Ca2+] nanodomains, but enhanced slower Ca2+-dependent transmission, dependent on global intraterminal [Ca2+] ([Ca2+]I). Surprisingly, coordinated multivesicular release persisted at Cplx3−/− synapses, although its onset was slowed. Light-dependent signaling at Cplx3−/− RB→AII synapses was sluggish, owing largely to increased asynchronous release at light offset. Consequently, propagation of RB output to retinal ganglion cells was suppressed dramatically. Our study links Cplx3 expression with synapse and circuit function in a specific retinal pathway and reveals a role for asynchronous release in circuit gain control

No full textIsaac Bashevish Singer egy életen át hajtogatta, hogy a bátyja, Joshua nálánál sokkalta nagyobb író volt. Nem hittünk neki, mert nála nagyobbat e műfajban elképzelni nemigen tudtunk, és mert Joshua Singer írása akkor még nem jutott el hozzánk. Aztán kiderült, hogy I. B. Singernek ebben is igaza volt. Attól ő még vitathatatlanul a novella koronázatlan királya marad, hogy kiderült: Joshua Singer valóban nagymestere a regénynek. Az Askenázi fivérek olyan bravúrosan van felépítve, úgy csavarodnak-gabalyodnak egymásba kibogozhatatlanul a szálak, hogy azt a mai napig kevesen tudnák utána csinálni. Majd' hatszáz oldalon végigpereg a századforduló és századelő lengyel zsidóságának döbbenetes élete, elképesztő nyomora, az iparosodás és a vele együtt kivirágzó antiszemitizmus félelmetes légköre. És az öntudatra ébredő munkásosztály létért való küzdelme, a hirtelen meggazdagodás és az ugyanolyan váratlan összeomlás minden téren. Hogy a korral járó érdekekről és érdekellentétekről, érdekházasságokról és egyéb összefonódásokról ne is beszéljünk. Kár, hogy Joshua Singer korán meghalt, hogy nem hagyott ránk annyit, amennyit a bátyja, I. B., de reméljük, hogy azt a keveset most - pótolva a lemaradást - sorra átadhatjuk az olvasónak.

Structure-function relationship studies of the cytochrome bd oxidase of Escherichia coli
No full textThe cytochrome bd oxidase complex is one of two terminal oxidases which are components of the aerobic respiratory chain of Escherichia coli. This membrane-bound oxidase catalyzes the two-electron oxidation of ubiquinol and the four-electron reduction of oxygen to water. Enzyme turnover generates proton and voltage gradients across the bilayer. The oxidase is a heterodimer containing three heme prosthetic groups, b\sb{558}, b\sb{595}, and d. To explain the functional properties of the oxidase, a simple model has been proposed in which the heme prosthetic groups define two separate active sites on opposite sides of the membrane at which the oxidation of ubiquinol (heme b\sb{558}) and the reduction of oxygen to water (hemes b\sb{595} and d) take place. Two histidines, His19 and His186, both in subunit I have been shown to affect the incorporation of the hemes as well as the activity of the oxidase. His19 is proposed to be an axial ligand to either b\sb{595} or d hemes, whereas His186 is believed to be one of the two axial ligands to heme b\sb{558}.This thesis describes a combination of molecular biology, biophysical characterization and use of artificial proteases to try to understand the structure-function relationship of the cytochrome bd oxidase. A novel experiment is described in detail to show proximity relationships between sites on the surface of the two subunits of the oxidase. The artificial protease iron (S)-1- (p-(bromoacetamido)benzyl) -EDTA (Fe-BABE) was conjugated to selective reactive cysteines placed in subunits I and II and then activated with \rm H\sb2O\sb2 and ascorbate, and hydrolysis products were isolated and analyzed. Among other results, we found that residues 39 and 48 both of subunit II are within 12A of residues 255 and 337 of subunit I in the putative quinone-binding domain (Q-loop).Site-directed mutagenesis and biophysical characterization were used: to construct a functional cytochrome bd oxidase devoid of cysteinyl residues, to try to determine the remaining ligands to the heme groups and also to identify residues that are involved in the oxidation and/or binding of ubiquinol. A successful construction of a cysteine-less oxidase is described in detail which appears to have the high-spin heme, heme b\sb{595}, being converted to a low-spin heme upon purification. Also described is some work done in collaboration with members of our laboratory in the determination of the remaining axial ligands to the heme groups. Met393 is proposed to be the second axial ligand to heme b\sb{558} and His19 might be involved in the ligation of heme b\sb{595}.Made available in DSpace on 2011-05-07T14:25:37Z (GMT).

Restructuring the international telecommunication union in a decade of development, 1985-1994 national sovereignty vs. the free flow of information
No full textAlthough the International Telecommunication Union is the oldest existing international treaty organization in the world, it has attracted relatively little scholarly study or media attention aside from recent debates about its proposed role in Internet governance and “bridging the digital divide.” Utilizing the published “Final Acts” of the Union’s periodic conferences, this study explores the history of the ITU—with a particular focus on the decade between the Maitland Report in 1985 and the Union’s most recent restructuring in 1994—in order to illustrate how the Union has evolved, both structurally and in terms of policy and purview, in response to new communications technologies and changing political, economic and social climates. I argue that ITU regulations have historically been the result of political considerations aimed at maintaining the sovereignty principle, the right of each member-state to regulate information networks within its borders. This principle has consistently proven antithetical to the Union’s stated purpose, and has generated further ambiguities and conflicts in recent debates as delegates have attempted to extend it to regulation of the borderless Internet.M.A.Includes bibliographical referencesJoshua Harri
Effect of changes in testing parameters on the cost-effectiveness of two pooled test methods to classify infection status of animals in a herd
No full textMonte Carlo simulation was used to determine optimal fecal pool sizes for identification of all Mycobacterium avium subsp. paratuberculosis (MAP)-infected cows in a dairy herd. Two pooling protocols were compared: a halving protocol involving a single retest of negative pools followed by halving of positive pools and a simple protocol involving single retest of negative pools but no halving of positive pools. For both protocols, all component samples in positive pools were then tested individually. In the simulations, the distributions of number of tests required to classify all individuals in an infected herd were generated for various combinations of prevalence (0.01, 0.05 and 0.1), herd size (300, 1000 and 3000), pool size (5, 10, 20 and 50) and test sensitivity (0.5–0.9). Test specificity was fixed at 1.0 because fecal culture for MAP yields no or rare false-positive results. Optimal performance was determined primarily on the basis of a comparison of the distributions of numbers of tests needed to detect MAP-infected cows using the Mann–Whitney U test statistic. Optimal pool size was independent of both herd size and test characteristics, regardless of protocol. When sensitivity was the same for each pool size, pool sizes of 20 and 10 performed best for both protocols for prevalences of 0.01 and 0.1, respectively, while for prevalences of 0.05, pool sizes of 10 and 20 were optimal for the simple and halving protocols, respectively. When sensitivity decreased with increasing pool size, the results changed for prevalences of 0.05 and 0.1 with pool sizes of 50 being optimal especially at a prevalence of 0.1. Overall, the halving protocol was more cost effective than the simple protocol especially at higher prevalences. For detection of MAP using fecal culture, we recommend use of the halving protocol and pool sizes of 10 or 20 when the prevalence is suspected to range from 0.01 to 0.1 and there is no expected loss of sensitivity with increasing pool size. If loss in sensitivity is expected and the prevalence is thought to be between 0.05 and 0.1, the halving protocol and a pool size of 50 is recommended. Our findings are broadly applicable to other infectious diseases under comparable testing conditions.ID: S0167587710000085; M3: Article; Accession Number: S0167587710000085; Author: Locksley L. McV.

De la culture cherokee et de l'identité amérindienne : un entretien avec Joshua Nelson
No full textInternational audienceProfessor Joshua B. Nelson, a citizen of the Cherokee Nation and a native Oklahoman, is an associate professor of English at the University of Oklahoma, whose work focuses on American Indian literature and film. He is also affiliated faculty with the departments of Film and Media Studies, Native American Studies, and Women’s and Gender Studies.We seized the opportunity of his presence in Europe on a research project to invite him in early April 2023 to the Université de Picardie Jules Verne in Amiens, where we interviewed him about his work.Nelson’s book, Progressive Traditions: Identity in Cherokee Literature and Culture, published in 2014 by the University of Oklahoma Press, sought to dismantle the assimilated/traditional dichotomy in American Indian literary criticism. More recently, he has been coproducer and narrator of the PBS documentary Searching for Sequoyah (directed by James Fortier and coproduced by Native author LeAnne Howe), about the eponymous figure who created the Cherokee syllabary in 1821 and later tried to reunite the various bands of his nation. Nelson was in Europe to retrace the trajectory of two Native American veterans of World War II and Medal of Honor awardees, Ernest Childers (Muscogee/Creek) and Jack Montgomery (Cherokee), about whom he is preparing his own documentary. Childers and Montgomery served in the 45th Infantry Division, headquartered in Oklahoma and comprising a large share of Native American soldiers. Known as the “Thunderbirds,” a legendary Indigenous American creature, the division took part in the campaigns of Sicily, Italy, France, and Germany (it liberated the Dachau concentration camp near Munich) during World War II, before being disbanded in 1968
