Cellular and Molecular Signatures of Oxidative Stress in Bronchial Epithelial Cell Models Injured by Cigarette Smoke Extract

2022

Exposure of the airways epithelium to environmental insults, including cigarette smoke, results in increased oxidative stress due to unbalance between oxidants and antioxidants in favor of oxidants. Oxidative stress is a feature of inflammation and promotes the progression of chronic lung diseases, including Chronic Obstructive Pulmonary Disease (COPD). Increased oxidative stress leads to exhaustion of antioxidant defenses, alterations in autophagy/mitophagy and cell survival regulatory mechanisms, thus promoting cell senescence. All these events are amplified by the increase of inflammation driven by oxidative stress. Several models of bronchial epithelial cells are used to study the molec…

Insect pests of the Herbarium of the Palermo botanical garden and evaluation of semiochemicals for the control of the key pest Lasioderma serricorne …

2020

Abstract The herbaria are scientific tools of great importance that preserve extinct, rare, endemic, and common plant species and also have importance as Cultural Heritage for their historical and esthetical value. Herbaria can be infested by several insect pests feeding on dried plants, and their management is often complicated and difficult as the use of chemical insecticides can have negative drawbacks. This suggests a strong need for alternative control tools such as the use of semiochemicals to develop Integrated Pest Management (IPM) programs. In order to identify the main insect pests that determine the damages on the exsiccata stored in the Palermo Botanical Garden's Herbarium, one …

Essential oil characteristics of wild Sicilian oregano populations in relation to environmental conditions

2014

A study was carried out on the essential oil of Origanum vulgare ssp. hirtum (Link) Ietswaart taken from thirteen wild populations found in different parts of Sicily, Italy. The aim of the study was to evaluate the relationship that exists between essentials oil extracted from Sicilian wild populations of O. vulgare ssp. hirtum (Link) Ietswaart and various weather/climate and topographic factors in order to provide more information on aspects that influence the production potential of this species. The essential oils from the samples were extracted by hydrodistillation and analyzed by a combination of gas chromatography-flame ionization detector (GC-FID) and GC-mass spectrometry (GC-MS); se…

Korelācija starp jaundzimušā Apgares vērtējumu, nabassaites asins gāzu parametriem un KTG

2018

Pētījuma mērķis. Izpētīt vai pastāv ticama sakarība starp KTG pierakstu dzemdībās un jaundzimušā iznākumu, salīdzinot KTG ar nabassaites asins gāzu parametriem un Apgares vērtējumu 5. minūtē. Pētījuma jautājums. Vai balstoties uz KTG pierakstu dzemdībās, būtu pamatoti ņemt nabassaites asinis jaundzimušā veselības stāvokļa izvērtēšanai gadījumos, kad Apgares vērtējums ir labs (>7 ballēm) un nav citu objektīvu datu par iespējamo hipoksiju. Metodika un materiāli. Paula Stradiņa KUS Perinatālās aprūpes centrā divu mēnešu garumā visās dzemdībās ar gestācijas laiku >35+0 nedēļām tika ņemtas asinis no nabassaites asinsvadiem, lai noteiktu skābju-sārmu līdzsvaru tajās.

Myths of Violence and Female Storytelling in Margaret Atwood’s The Handmaid’s Tale and Kate Atkinson’s Human Croquet

2016

Stories of violence and oppression from classical mythology and fairy tales are redeployed in two novels by Atwood (1985) and Atkinson (1997) as archetypal pre-texts that impact on plot and narrative process. Although they are very different in genre and theme, both novels present first-person female narrators who are trapped in a claustrophobic present, and pose the question of the extent to which a story can be told from within the boundaries traced by myth, fairy tales and quasi-mythical literary texts. Clearly indebted to Orwell’s Nineteen Eighty-Four, The Handmaid’s Tale depicts a dystopian world where women live segregated by a male regime. References to the tale of Little Red Cap, cl…

Cigarette smoke increases BLT2 receptor functions in bronchial epithelial cells: in vitro and ex vivo evidence

2013

Summary Leukotriene B4 (LTB4) is a neutrophil chemotactic molecule with important involvement in the inflammatory responses of chronic obstructive pulmonary disease (COPD). Airway epithelium is emerging as a regulator of innate immune responses to a variety of insults including cigarette smoke, the major risk factor for COPD. In this study we have explored whether cigarette smoke extracts (CSE) or soluble mediators present in distal lung fluid samples (mini-bronchoalveolar lavages) from smokers alter the expression of the LTB4 receptor 2 (BLT2) and peroxisome proliferator-activated receptor-α (PPAR-α) in bronchial epithelial cells. We also evaluated the effects of CSE on the expression of i…

Taxonomic complexity in the halophyte Limonium vulgare and related taxa (Plumbaginaceae): insights from analysis of morphological, reproductive and k…

2014

Part of a special issue on halophytes and saline adaptations Background and Aims Limonium is awell-known example of a group of plants that is taxonomically complex due to certain biological characteristics that hamper species’ delineation. The closely related polyploid species Limonium vulgare Mill., L. humile Mill. and L. narbonense Mill. are defined species and can be used for studying patterns of morphological and reproductive variation. The first two taxa are usually found in Atlantic Europe and the third in the Mediterranean region, but a numberof intermediate morphological formsmay be present alongside typical examples of these species. This study attempts to elucidate morphological, …

Los viajes de Maximiliano a España y Brasil: el largo camino hacia el imperio mexicano

1970

En mayo de 1864 Maximiliano de Austria llega a la costa mexicana en el que será su último viaje, que culminará con su ejecución tres años después. Mucho se ha escrito sobre las razones que le impulsaron a aceptar la corona de México, un país tan alejado en todos los sentidos de su entorno cultural, sin embargo, años antes Maximiliano había viajado a España y a Brasil (a España en dos ocasiones) y estas experiencias, si no determinantes, influyeron en gran medida en la decisión del Archiduque, que vio la oportunidad de hacer realidad un sueño que se gestó en su viaje a España y se afianzó durante su estancia en Brasil, como se puede extraer de sus memorias de viaje. In May of 1864, Maximilia…
