Booster vaccination after neonatal priming with acellular pertussis vaccine.
2010
After a birth dose of acellular pertussis (aP) and diphtheria (DT)aP-hepatitis B virus (HBV)-inactivated polio vaccine (IPV)/ Haemophilus influenza type b (Hib) at 2, 4, and 6 months, a booster dose of DTaP-HBV-IPV/Hib at 12 to 23 months induced strong anti-pertussis booster responses. Thus, neonatal aP priming did not lead to immune tolerance to pertussis antigens. However, it elicited bystander interference on HBV, Hib, and diphtheria responses.
Innovación docente y TIC desde la perspectiva de la docencia en Derecho
2020
Las tecnologías de la información y la comunicación son un elemento extraordinario para innovar en el ámbito educativo, tal y como ha mostrado la situación generada por el COVID-19. Así, en el ámbito del Derecho son múltiples las posibilidades que se derivan de la implementación de estas herramientas para mejorar el nivel de la enseñanza y facilitar la incorporación de los estudiantes al mundo laboral. Ahora bien, la tecnología no es un fin en sí mismo, por lo que habrá que valorar la introducción de estas herramientas como complemento y no como un sustitutivo de la tarea educativa, especialmente en el ámbito del Derecho, que exige la formación de juristas con una visión integral de la real…
COVID-19 Pandemic: Prevention and protection measures to be adopted at the workplace
2020
Introduction: SARS-CoV-2, identified in Wuhan, China, for the first time in December 2019, is a new viral strain, which has not been previously identified in humans; it can be transmitted both by air and via direct and indirect contact; however, the most frequent way it spreads is via droplets. Like the other viruses belonging to the same family of coronaviruses, it can cause from mild flu-like symptoms, such as cold, sore throat, cough and fever, to more severe ones such as pneumonia and breathing difficulties, and it can even lead to death. Since no effective specific drug therapy has been found yet, nor any vaccine capable of limiting the spread of this pathogen, it is important for way…
Behind the mask: Rethinking the use of face masks while exercising
2021
there is an ongoing global effort against COVID-19 pan-demic. As vaccination is applied globally (predominantly onat-risk populations), various measures such as temporaryself-quarantine, social distancing, increased hand hygiene,and wearing a face mask (FM) proposed by the World HealthOrganization (WHO) and various governments worldwide arestill in place as primary means of preventing further dissemi-nation. In many instances, wearing a FM became mandatorywhen a person is in a closed space while being accompa-nied by others. Many individuals are therefore apprehensivein terms of maintaining their usual physical activity rout-ines and staying safe in the midst of the outbreak. Asa result, it…
Multiorgan Involvement in SARS-CoV-2 Infection: The Role of the Radiologist from Head to Toe
2022
Radiology plays a crucial role for the diagnosis and management of COVID-19 patients during the different stages of the disease, allowing for early detection of manifestations and complications of COVID-19 in the different organs. Lungs are the most common organs involved by SARS-CoV-2 and chest computed tomography (CT) represents a reliable imaging-based tool in acute, subacute, and chronic settings for diagnosis, prognosis, and management of lung disease and the evaluation of acute and chronic complications. Cardiac involvement can be evaluated by using cardiac computed tomography angiography (CCTA), considered as the best choice to solve the differential diagnosis between the most common…
RNA dependent DNA polymerase in cells of xeroderma pigmentosum
1971
Abstract Cells from X.P. ∗ skin contain an RNA dependent DNA polymerase, while in cells from normal skin this enzyme is lacking. This finding stimulates the thought that carcinogenesis in X.P. cells is due to an infection with an oncogenic RNA virus.
Comparative efficacy of Zataria multiflora Boiss., Origanum compactum and Eugenia caryophyllus essential oils against E. coli O157:H7, feline caliciv…
2013
Abstract Ready-to-eat salads using baby-leaf and multi-leaf mixes are one of the most promising developments in the fresh-cut food industry. There is great interest in developing novel decontamination treatments, which are both safe for consumers and more efficient against foodborne pathogens. In this study, emulsions of essential oils (EOs) from Origanum compactum (oregano), Eugenia caryophyllus (clove), and Zataria multiflora Boiss (zataria) were applied by spray (0.8 ml) after the sanitizing washing step. The aim was to investigate their ability to control the growth of potentially cross-contaminating pathogens and endogenous microbiota in commercial baby leaves, processed in a fresh-cut…
A Shock to the System: HIV among Older African Women in Zimbabwe
2018
HIV remains a threat to the ordinary everyday life of older woman in African society. In what can be called “a reality shock,” HIV challenges most of the ordinary everyday endeavors in conservative African societies as it imposes new Western prevention, treatment, and health-management methods over long-held African traditions. The reality of the “Western” HIV epidemic, and its impact on the “African” ordinary everyday life, demands that the infected undergo a paradigm shift in order for them to live harmoniously within their society. This calls for a re-examination of traditional values and a strong sense of responsibility, courage, and determination to remain relevant and not be considere…
Killer toxin-secreting double-stranded RNA mycoviruses in the yeasts Hanseniaspora uvarum and Zygosaccharomyces bailii.
1994
Killer toxin-secreting strains of the yeasts Hanseniaspora uvarum and Zygosaccharomyces bailii were shown to contain linear double-stranded RNAs (dsRNAs) that persist within the cytoplasm of the infected host cell as encapsidated virus-like particles. In both yeasts, L- and M-dsRNAs were associated with 85-kDa major capsid protein, whereas the additional Z-dsRNA (2.8 kb), present only in the wild-type Z. bailii killer strain, was capsid protein, whereas the additional Z-dsRNA (2.8 kb), present only in the wild-type Z. bailii killer strain, was shown to be encapsidated by a 35-kDa coat protein. Although Northern (RNA) blot hybridizations indicated that L-dsRNA from Z. bailii is a LA species,…
Burden of HIV and hepatitis C co-infection: the changing epidemiology of hepatitis C in HIV-infected patients in France.
2015
Équipe UB/CHU (EA) Pôle MERS CT3 Hors Enjeu; International audience; Background & AimsTo better evaluate the HIV-HCV co-infection burden in the context of new effective HCV treatment. MethodsWe reviewed all the epidemiological data available on HCV-related disease in HIV-infected patients in France. Sources of data have been selected using the following criteria: (i) prospective cohorts or cross-sectional surveys; (ii) conducted at a national level; (iii) in the HIV-infected population; (iv) able to identify HCV co-infection and chronic active hepatitis C (HCV RNA positive); and (v) conducted during the period 2003-2012. ResultsThe overall prevalence of HIV-HCV co-infection has decreased fr…
