Inhibition of expression of natural UAG suppressor glutamine tRNA in HIV-infected human H9 cells in vitro by Avarol.

1988

HTLV-IIIB-infected H9 cells are shown to contain a high level of the natural UAG suppressor glutamine tRNA(UmUG Gln); this tRNA has been demonstrated to be required for the synthesis of Moloney murine leukemia virus (Mo-MuLV)-encoded protease. After cultivation of HTLV-IIIB-infected H9 cells with Avarol at a concentration (1 microgram/ml), previously found to protect the cells against the cytopathic effects of HTLV-III, an almost complete inhibition of the synthesis of the tRNA(UmUG Gln) was observed. Moreover, we obtained some evidence that the processing of the HTLV-III precursor protein p53 to p24 is inhibited by Avarol in infected cells, suggesting that the compound interferes with the …

PHYSICAL ACTIVITY IN ADOLESCENCE LEVELS CHANGES AND FACTORS OF INFLUENCE

2021

Physical activity (PA) is considered a health imperative, so it is understandable that physical inactivity imposes a serious health threat. The fact that alarming decline in physical activity levels (PALs) occurs in adolescence is particularly concerning. Accordingly, the dissertation deals with PA issues among adolescents in regular conditions and during the COVID-19 pandemic. Generally, changes and correlates of the PALs in the period from 14 to 18 years of age and in the period of the COVID-19 pandemic are investigated. Four presented studies analyze the specified problems in adolescents from Croatia and Bosnia and Herzegovina and are among the first studies that examined this issue in S…

Tabaquismo activo y pasivo en personas adultas que viven con una pareja del mismo sexo en España

2018

Abstract Objective To assess the association between current active and passive tobacco smoking and living with a same-sex partner in Spain. Methods We analysed data from two cross-sectional national surveys of the Spanish population 15 years and older (2011-Encuesta Nacional de Salud en España and 2014-Encuesta Europea de Salud en España). Analyses included only people living with their partner. Associations were calculated using multiple logistic regressions adjusting for gender, social class and age. Results Current active and passive smoking were significantly associated with living with same sex partners (odds ratio: 2.71 and 2.88), and particularly strong among women. Conclusions Span…

Exposure of heat-not-burn tobacco effect on the quality of air and expiratory plume

2021

Abstract The increasing interest to avoid the consumption of regular tobacco has lead in the development of several types of devices to decrease the effects of this practice on active and bystanders. In this work, the impact of the use of new heat-not-burn (HnB) devices has been evaluated and compared with that of regular cigarettes and electronic cigarettes (e-cigs). Portable monitoring devices were employed for CO, CO2, particulate matter (PM) and volatile organic compounds (VOCs) to evaluate the quality of indoor air and expiratory plume of both, active and passive, users during these practices. It can be noticed that the levels of VOCs in active HnB smokers expiratory air are five times…

Monitoring of the smoking process by multicommutation Fourier Transform Infrared spectroscopy

2007

Abstract Nicotine was selected as the target molecule for monitoring of the smoking process by multicommutation Fourier Transform Infrared spectroscopy (FTIR). The method involved the use of CHCl3 for on-line extraction of nicotine from tobacco, cigarette filters and tobacco ash from NH4OH alkalinized samples, and absorbance measurement of the characteristic band at 1316 cm−1 in the stopped-flow mode, by obtaining the peak area in the range between 1334 and 1300 cm−1. Under the best operational conditions, the procedure developed provided a detection limit of 0.05 mg mL−1 nicotine, corresponding to 0.5 mg g−1 in the solid sample, a relative standard deviation less than 2.5%, and a sampling …

Determinants of Allergic Sensitization, Asthma and Lung Function: Results from a Cross-Sectional Study in Italian Schoolchildren

2020

Prenatal smoking exposure and early-life respiratory infections are major determinants of asthma during childhood. We investigate the factors influencing allergic sensitization (AS), asthma, and lung function in children and the balance between individual and environmental characteristics at different life stages. 1714 children aged 7&ndash

The complete genome sequence of Lamium mild mosaic virus, a member of the genus Fabavirus

2013

Springer-Verlag Wien 2013 Abstract Lamium mild mosaic virus (LMMV) is the only one of the five members of the genus Fabavirus for which there are no nucleotide sequence data. In this study, the complete genome sequence of LMMV was determined and compared with the available complete genome sequences of other members of the genus Fabavirus. The genome was the largest of the genus but maintained the typical orga- nization, with RNA 1 of 6080 nucleotides (nt), RNA 2 of 4065 nt, and an unusually long 3 0 untranslated region in RNA 2 of 603 nt. Phylogenetic analysis of the amino acid sequences of the protease-polymerase (Pro-Pol) region and the two coat proteins confirmed that LMMV belongs to a d…

Highly Efficient Virus-induced Gene Silencing (VIGS) in California Poppy (Eschscholzia californica): An Evaluation of VIGS as a Strategy to Obtain Fu…

2007

†Background and Aims Eschscholzia californica (California poppy) is an emerging model plant for ‘evo‐devo’ studies from the basal eudicot clade of Papaveraceae. California poppy has a relatively small genome, a short life cycle and, most importantly, it is amenable for transformation. However, since this transformation protocol is time consuming, virus-induced gene silencing (VIGS) was evaluated as a fast method to obtain functional data for California poppy genes. †Methods Commercially available California poppy plants were infiltrated with Agrobacterium tumefaciens carrying the tobacco rattle virus plasmids pTRV1 and pTRV2. pTRV2 contained part of the eschscholzia Phytoene Desaturase (EcP…
