Neuropeptidome regulation after baculovirus infection. A focus on proctolin and its relevance in locomotion and digestion

2020

AbstractBaculoviruses constitute a large group of invertebrate DNA viruses, predominantly infecting larvae of the insect order Lepidoptera. During a baculovirus infection, the virus spreads throughout the insect body producing a systemic infection in multiple larval tissues. Some behavioral and physiological changes in lepidopteran larvae have been described following a baculovirus infection and those changes could be connected with alterations in the host’s central nervous system (CNS). As a main component of the CNS, neuropeptides are small protein-like molecules functioning as neurohormones, neurotransmitters or neuromodulators. These peptides are involved in regulating animal physiology…

A proctolin-like peptide is regulated after baculovirus infection and mediates in caterpillar locomotion and digestion

2022

Baculoviruses constitute a large group of invertebrate DNA viruses, predominantly infecting larvae of the insect order Lepidoptera. During a baculovirus infection, the virus spreads throughout the insect body producing a systemic infection in multiple larval tissues, included the central nervous system (CNS). As a main component of the CNS, neuropeptides are small protein-like molecules functioning as neurohormones, neurotransmitters, or neuromodulators. These peptides are involved in regulating animal physiology and behavior and could be altered after baculovirus infection. In this study, we have investigated the effect of Spodoptera exigua multiple nucleopolyhedrovirus (SeMNPV) infection …

Chiral hemicucurbit[8]uril as an anion receptor: selectivity to size, shape and charge distribution

2017

A novel eight-membered macrocycle of the hemicucurbit[n]uril family, chiral (all-R)-cyclohexanohemicucurbit[8]uril (cycHC[8]) binds anions in a purely protic solvent with remarkable selectivity. The cycHC[8] portals open and close to fully encapsulate anions in a 1 : 1 ratio, resembling a molecular Pac-Man™. Comprehensive gas, solution and solid phase studies prove that the binding is governed by the size, shape and charge distribution of the bound anion. Gas phase studies show an order of SbF6− ≈ PF6− > ReO4− > ClO4− > SCN− > BF4− > HSO4− > CF3SO3− for anion complexation strength. An extensive crystallographic study reveals the preferred orientations of the anions within the octahedral cav…

Volatile components of Centaurea calcitrapa L. and Centaurea sphaerocephala L. ssp. sphaerocephala, two Asteraceae growing wild in Sicily

2006

The volatile components of the flowerheads of Centaurea calcitrapa L. (C.c.) and Centaurea sphaerocephala L. ssp. sphaerocephala (C.s.) were obtained by hydrodistillation and identified by GC and GC–MS. Altogether 96 components were identified, 66 in C. calcitrapa and 68 in C. spaerocephala, mostly fatty acids (32.8%, C.c. and 44.2%, C.s.) and hydrocarbons (32.3%, C.c. and 15.9%, C.s.). 9,12-Octadecadienoic acid (15.8%, C.c.) and hexadecanoic acid (30.7%, C.s.) were the most abundant fatty acids; tricosane (8.0%, C.c.) and heptacosane (4.9%, C.s.) were the main hydrocarbons. Sesquiterpenes were also present as hydrocarbons (10.1% for 14 components in C.c. and 9.2% for 13 components in C.s.)…

Alpha-lipoic acid: molecular mechanisms and therapeutic potential in diabetes.

2015

International audience; Diabetes is a chronic metabolic disease with a high prevalence worldwide. Diabetes and insulin resistance are associated with the development of cardiovascular and nervous diseases. The development of these disorders reflects complex pathological processes in which the oxidative stress caused by reactive oxygen species (ROS) and reactive nitrogen species (RNS) plays a pivotal role. It is widely accepted that diabetes impairs endothelial nitric oxide synthase (eNOS) activity and increases the production of ROS, thus resulting in diminished NO bioavailability and increased oxidative stress. Alpha-lipoic acid (LA) possesses beneficial effects both in the prevention and …

Molecular dynamics of electrosprayed water nanodroplets containing sodium bis(2-ethylhexyl)sulfosuccinate

2013

The behavior of aqueous solutions of sodium bis(2-ethylhexyl)sulfosuccinate (AOTNa) subject to electrospray ionization (ESI) has been investigated by molecular dynamics (MD) simulations at three temperatures (350, 500 and 800 K). We consider several types of water nanodroplets containing AOTNa molecules and composed of a fixed number of water molecules (1000), N(AOT)(0) AOT(-) anions (N(AOT)(0) =  0, 5, 10) and N(Na)(0) sodium ions (N(Na)(0) =  0, 5, 10, 15, 20): in a short time scale (less than 1 ns), the AOTNa molecules, initially forming direct micelles in the interior of the water nanodroplets, are observed in all cases to diffuse nearby the nanodroplet surface, so that the hydrophilic …

Tohtoriopiskelija julkaisufoorumeilla: kokemuksia puheviestinnän väitöskirjaa tekevien artikkelipajasta

2010

Artikkelissa esitellään tohtoriopiskelijoille järjestettyä artikkelipajaa. Sen tarkoituksena oli tarjota evästystä sekä väitöskirjaan sisältyvien artikkeleiden että post doc -julkaisujen suunnitteluun ja julkaisufoorumien tutkiskeluun. Taustalla oli kokemus siitä, että artikkeliväitöskirjan ohjausprosessi poikkeaa monin tavoin monografiaväitöskirjan ohjauksesta. Vaikka tohtoriopiskelija sopii ohjaajansa kanssa väitöskirjaan tulevista artikkeleista, voidaan julkaisemiseen liittyvää oppimista tukea yhteisesti järjestettävällä artikkelipajalla. nonPeerReviewed

Pave Frans – bedring, men ingen løsning for en kirke i krise

2020

Kritiske ytringer om pave Frans framsettes som regel på konservativt og tradisjonalistisk katolsk hold. Denne artikkelen sikter på å presentere en progressivt fundert kritikk av det nåværende pontifikatet. Frans krediteres for gode intensjoner, pastoralt lederskap og motstand mot klerikalistiske holdninger. Men da han ikke har maktet – og kanskje heller ikke tilstrekkelig klart ønsket – å endre kirkens utdaterte hierarkiske struktur, er han ingen løsning på de store utfordringene Den katolske kirke lenge har stått overfor. Artikkelen har et aktuelt og kritisk sikte, og den preges i større grad av normative vurderinger enn mange andre faglige bidrag i dag.

Strategies to Improve the Potential Functionality of Fruit-Based Fermented Beverages

2021

It is only recently that fermentation has been facing a dynamic revival in the food industry. Fermented fruit-based beverages are among the most ancient products consumed worldwide, while in recent years special research attention has been granted to assess their functionality. This review highlights the functional potential of alcoholic and non-alcoholic fermented fruit beverages in terms of chemical and nutritional profiles that impact on human health, considering the natural occurrence and enrichment of fermented fruit-based beverages in phenolic compounds, vitamins and minerals, and pro/prebiotics. The health benefits of fruit-based beverages that resulted from lactic, acetic, alcoholic…
