The concentration of radon-222 in air was measured during a flight from Miami to Barbados to Dakar and return; concentrations ranged from 1 to 55 picocuries per standard cubic meter of air and were highest in areas of dense haze, which were present along most of the flight path across the Atlantic Ocean. The haze is attributed to dust originating from the arid regions of western Africa. Radon-2...

Methods Ten HIV-1 ESN in HIV-discordant couples were enrolled at the Fann University hospital, Dakar, Senegal. Thirty HIV-1 infected patients (10 HIV-1 non transmitted partners in discordant coupes and 20 HIV-1 infected partners in HIV-concordant couples) and 10 HIV-negative unexposed subjects were included as controls. Levels of CD107a and b, and CD107a/b+IFN-g+ in CD8+ T cells sub-set were me...

Strain FF9T was isolated in Dakar (Senegal) from a blood-culture taken from a 16-month-old child. MALDI-TOF analysis did not allow for identification. After sequencing, strain FF9T exhibited 98.18% similarity with the 16SrRNA sequence of Paenibacillus uliginis. A polyphasic study of phenotypic and genomic analyses showed that strain FF9T is Gram variable, catalase-positive, and presents a genom...

Strain FF10(T) (= CSUR P1489 = DSM 100884) was isolated from the oral cavity of a lizard (Varanus niloticus) in Dakar, Senegal. Here we used a polyphasic study including phenotypic and genomic analyses to describe the strain FF10(T). Results support strain FF10(T) being a Gram-positive coccus, facultative anaerobic bacterium, catalase-negative, non-motile and non-spore forming. The sequenced ge...

Coronavirus infectious disease 2019 (COVID-19) pandemic is a global public health issue due to new coronavirus called severe acute respiratory syndrome virus 2 (SARS-Cov-2).

Abstract. There has been a proliferation of contemporary art biennials in the past 20 years, especially cities outside North America and Europe. What represent to their host what is represented at these events reveal great deal about significance this proliferation. The biennial platform entails formalistic notions representation with regards place branding or selection artists as emissaries co...
