Isolation of in vivo intermediates in iron sulfur cluster biogenesis
… assembly including the <i>nif, suf,</i> and <i>isc</i> systems. The <i>nif</i> system makes iron-sulfur clusters for nitrogenase production, while both the <i>suf</i> and <i>isc</i> systems provide iron-sulfur clusters for general cellular use. In <i>Azotobacter vinelandii</i> the isc operon …

Perfil epidemiológico e análise microbiológica de infecção de sítio cirúrgico em pacientes humano e animal de companhia
A infecção de sítio cirúrgico (ISC) tem sido apontada como a terceira causa mais comum de infecção nosocomial. Este estudo objetivou determinar o perfil epidemiológico das ISCs e sua associação aos fatores de risco descritos. Trata-se de um estudo transversal, realizado no Hospital São João Batista …

INTRA-MITOCHONDRIAL INJURY DURING ISCHEMIA-REPERFUSION
Cardiac injury is increased following ischemia-reperfusion. Mitochondria are the “effector organelles” that are damaged during ischemia (ISC) when there is no blood flow. Resumption of metabolism by damaged mitochondria during reperfusion (REP) results in increased cell injury. Current therapeutic …

Controlled Expression and Functional Analysis of the Iron-Sulfur Cluster Biosynthetic Machinery in Azotobacter vinelandii
… for the functional analysis of the A. vinelandii isc genes, whose products are involved in the maturation of [Fe-S] proteins. For this analysis the scrX gene, contained within the sucrose catabolic regulon, was replaced by the A. vinelandii iscS, iscU, iscA, hscB, hscA, fdx, iscX gene cluster, …

Development of a New Parallel In-Situ Combustion Simulator
… method for heavy oil, In-Situ Combustion (ISC) shows its great potential accompanied by technological advances in recent years. Reservoir simulation will play an indispensable role in the prediction of the implementation of ISC projects. With the computational complexity, it is imperative …

Ultrafast electron transfer and intersystem crossing in bimetallic molecules
… role in driving ET and intersystem crossing (ISC) on the ultrafast timescale. In this thesis, ultrafast optical and X-ray techniques are used to characterize the ET and ISC dynamics of a prototypical bimetallic FeIICoIII molecule following metal-to-metal charge transfer (MMCT) excitation. …

Pharmacological characterisation of selective Y4 and dual Y2/Y4 receptor agonists: novel targets for putative anti-obesity therapies
… chambers and changes in short-circuit current (Isc) recorded. In addition, receptor specificity of the most promising agonists was dissected using Y1 and Y2 antagonists. Furthermore, an assessment of Y4 receptor desensitisation was made by application of a subsequent addition of the native …

Effects on Campostoma oligolepis Digestive Morphology and Gut Microbiota Composition across a Gradient of Urbanization
… different levels of impervious surface coverage (ISC). Individuals were collected from each sample site in the summer of 2016 between late July and early September. A second round of sampling was conducted in the fall between mid-October and mid-November. The gut length to total length ratio was …

The Hippo Signaling Pathway in Organ Size Control and Regeneraton
… recent identification of intestinal stem cells (ISCs) has made the Drosophila adult midgut an excellent model to study adult stem cell biology. Multiple signaling pathways have been implicated in the regulation of ISC proliferation, self-renewal and differentiation. I obtained evidence that Hpo …

Synthesis and Photophysics of Varied Substituted DPNDs for Potential PDT Applications
… underwent equally non-radiative deactivation and ISC to populate the corresponding triplet manifold. Time-resolved Transient absorption spectroscopy (TAS) confirmed the ISC and triplet formation. Moreover, singlet-oxygen generation using these DPNDs as sensitizers yielded quantum yields (ΦΔ) ≈ …

Investigating how Notch, and JAK/STAT Signaling Synergistically Regulate Intestinal Stem Cell Homeostasis Using Engineered Optogenetic Alleles
… paired with Notch knockdown causes substantial ISC overproliferation, leading to the formation of large ISC tumors spanning the entire midgut. Quantitative assessment of ISC pools confirmed that Notch and JAK/STAT signaling work in a synergistic manner, rather than an additive manner, to …

Perceived risk of inherited susceptibility to cancer
… risk of inherited susceptibility to cancer (ISC) historically has been determined by objective measures, which neither emphasize how people with ISC perceive their risk of cancer, nor address the meaning of being at risk. The few studies of perceived risk of ISC provide sparse data regarding …

I. Kinetic Modeling of Surface Reactions II. Computational Design of Organic Semiconductors
… states with fast T₁ → S₁ intersystem crossing (ISC) and S₁ → S₀ radiative decay. Using molecular dynamics (MD) and the time-dependent density functional theory (TDDFT), we consider conformational variation as a means to sample the parameter space, and then we examine the potential of direct …

The metabolism of iron-sulfur clusters during hydrogen peroxide stress in escherichia coli
… assembly system. E. coli normally relies on the Isc system for cluster assembly; however, when E. coli scavenger mutants were exposed to low-grade H2O2 stress, Suf was needed to maintain dehydratase activities. Experiments showed that Suf repaired damaged clusters in isopropylmalate isomerase but …

Characterization of Palmitic Acid Induced Lipotoxicity in Schwann Cells
… The data show that immortalized Schwann cell (iSC), as well as primary Schwann cell (pSC) cultures exposed to elevated levels of PA induced an apoptotic cell death that is dose and time-dependent. The earliest indication of cellular dysfunction was a decrease in Ca++ levels in the endoplasmic …
