Conformational dynamics of active site loops 5, 6 and 7 of enzyme Triosephosphate Isomerase: A molecular dynamics study

2018

AbstractTriosephosphate Isomerase is a glycolytic enzyme catalyzing the interconversion of Dihydroxyacetone phosphate to Glyceraldehyde-3-phosphate. The active site is comprised of three distinct loops loop-6, loop-7 and loop-8. Based on loop-6 and loop-7 conformation we describe the enzyme as Open TIM and Closed TIM. Various NMR, X-ray crystallography and QM/MM simulation techniques have provided glimpses of individual events of what is essentially a dynamic process. We studied the conformational changes of two distinct loops (loop-6 and loop-7) enveloping the active site, in the presence of natural substrate, reaction intermediates and inhibitor molecules, by means of microsecond atomisti…

At the height of the crisis, the international monetary system is powerless to reduce theinstability of exchange rates, the imbalance of the current account of balance ofpayments, instability of exchange rates and the development of speculation in financialmarkets the and the asymmetry between net exporters countries and net deficits countries.This thesis, which had the merit of opening new tracks in order to understand thecomplex relationships between global imbalances and the actual system, showed thatthese global imbalances are intrinsically linked to the failures of the internationalmonetary structure. To stop the deterioration of global imbalances, we propose that thesystem turns towar…

Periodontal status and the incidence of selected bacterial pathogens in periodontal pockets and vascular walls in patients with atherosclerosis and a…

2022

The aim of the study was to examine the periodontal status of patients with atherosclerosis and abdominal aortic aneurysms. The occurrence of 5 periodontopathogens was evaluated in periodontal pockets and atheromatous plaques together with specimens from pathologically changed vascular walls of aortic aneurysms. The study comprised 39 patients who qualified for vascular surgeries. Patients with periodontitis and concomitant atherosclerosis or aneurysms were enrolled in the study. Periodontal indices were evaluated, and subgingival plaque samples were examined together with atheromatous plaques or specimens from vascular walls to identify, by polymerase chain reaction (PCR), the following pe…

Benzo-Fused Periacenes or Double Helicenes? Different Cyclodehydrogenation Pathways on Surface and in Solution

2019

Controlling the regioselectivity of C-H activation in unimolecular reactions is of great significance for the rational synthesis of functional graphene nanostructures, which are called nanographenes. Here, we demonstrate that the adsorption of tetranaphthyl- p-terphenyl precursors on metal surfaces can completely change the cyclodehydrogenation route and lead to obtaining planar benzo-fused perihexacenes rather than double [7]helicenes during solution synthesis. The course of the on-surface planarization reactions is monitored using scanning probe microscopy, which unambiguously reveals the formation of dibenzoperihexacenes and the structures of reaction intermediates. The regioselective pl…

Probing the Merits of Different Event Parameters for the Identification of Light Charged Particles in CHIMERA CsI(Tl Detectors With Digital Pulse Sha…

2013

We investigated the merits of different event parameters in the identification of Light Charged Particles (LCPs) with CsI(Tl) scintillators read out by photodiodes at high incident energy (400 MeV/u). This investigation is made possible by digital signal processing the output signals. As in the conventional analogue case, the digitized signals allow the discrimination of light charged particles by computing the fast and slow components. In addition other identification parameters as the rise time of the output pulses of the CsI(Tl) come out nearly for free. Aim of this paper is the investigation of novel identification plots and the probe of their merits, in particular at relativistic energ…

Risk committee complexity and liquidity risk in the European banking industry

2021

Abstract The present study aims to investigate how bank governance characteristics are related to liquidity risk by analysing board composition, gender, and the risk committee. A dynamic panel data model is employed on a sample of European banks during the period after the financial crisis (from 2011 to 2017). Furthermore, we collect information about the profiles of the directors on the boards of banks, thereby creating five categories of risk committee members. To address the endogeneity issue, a generalised method of moments two-step estimator is implemented. The findings highlight that the fundamental role of the risk committee adequately shields banks against general liquidity risks. M…

Uloga glazbe u dubrovackom pastoralnom teatru u 16. stoljecu. (The Role of the Music in the Pastoral Theatre in Dubrovnik during the Sixteenth Centur…

2004

The 16th-century pastoral plays in Dubrovnik (Ragusa), like the Italian ones which inspired them, are marked by the strong presence of sounds, songs and choruses to increase the fantastical and sentimental emphasis of the performances. Their evolution, from Dzore Drzic eclogues to the pastorals of Antun Sasin, and through Mauro Vetranovic's "Orfeo", is characterized by the acquisition of a Petrarchian language in the Croatian pieces of Nikola Naljeskovic. In the Dubrovnik pastoral plays, unlike the Italian ones, the presence of shepherds, nymphs, and rustic men (the "vlasi", Engl. Walachians or Morlacks) as well as the fantastic and comic elements, is constant. Music supports a narrative fu…

Necrotizing periodontitis in the context of Takayasu s disease: report of a case

2011

Necrotizing periodontitis is characterized by gingival necrosis with bleeding and pain, and alveolar bone attachment loss. The disease is associated to spirochete and Prevotella intermedia infection, as well as to a series of bacterial infections, with an altered local host immune response and tissue destruction. We present the case of a 40-year-old woman with inflammatory vasculitis of the aorta and its main branches, known as Takayasu’s disease. In the course of treatment of the latter, she developed necrotizing periodontitis. In this case local factors such as abundant bacterial plaque accumulation secondary to a lack of tooth brushing, and the administration of methotrexate, may have pl…
